Definitions
- the present invention relates to toy roller coaster assemblies. More particularly, the present invention relates to a toy roller coaster assembly having magnetically attachable track sections, metallic balls for travel thereon, and a variety of structural and audiovisual features.
- Toy roller coaster assemblies are known in the toy and model fields. Such toy assemblies may include a variety of interlocking track pieces, support and connection means for building a roller coaster from the track pieces, and a small object such as a marble or ball, which is conveyed along the tracks of the roller coaster. Assemblies having multiple interchangeable elements are especially desirable, as such toys engage children's creativity and ingenuity. Toy roller coaster assemblies may further include special structural features that enhance their visual appearance and create exciting effects when the ball engages the feature. These features may include, for example, a “loop-the-loop” track section or a ball drop.
- the present invention provides a toy roller coaster assembly with visually striking magnetic features and with an integrated audiovisual system.
- the roller coaster assembly can include magnetically attachable track sections of different shapes, including special track sections such as a “loop-the-loop,” a ball drop, a magnetic bridge, and a magnetic U-turn; metallic balls that travel on the track sections; and an audiovisual system that that produces audio and visual effects when activated by the motion of the balls.
- Joint members can magnetically connect the track sections to each other and to a plurality of vertical supports, thereby facilitating a wide array of possible configurations.
- the audiovisual system can include a controller, a plurality of sensors positioned throughout the roller coaster assembly, and audio and video output devices. The audiovisual system is programmed to output voice and music samples, sound effects, graphic displays, animation sequences and video clips in conjunction with the motion of the balls through the circuit of the roller coaster assembly.

- FIGS. 1 and 2 illustrate a toy roller coaster assembly 10 constructed from multiple basic structural elements; namely, a plurality of track sections 12 , a plurality of columnar vertical supports 14 , and a plurality of joint members 16 , which connect the track sections 12 to each other and to the vertical supports 14 . Also included is a plurality of metal marbles or balls 18 that removably engage the track sections 12 .
- a lift track assembly 20 vertically conveys the balls 18 from the lowest level, or bottom B, of the roller coaster assembly 10 to the highest level, or top T, of the roller coaster assembly 10 .
- each of the track sections 12 comprises a pair of cylindrical rods 22 which are spaced in a parallel formation, so as to allow the balls 18 to roll thereon.
- the rods 22 are preferably made from a plastic material.
- Each rod 22 includes a disk 24 embedded in each of its opposed ends, the purpose of which will be discussed hereinafter.
- Each disk 24 is made from either a magnetic material or a magnetically conductive metal.
- the rods 22 are pre-formed to be straight (see FIG. 3A ), curved (see FIG. 3B ), or looped (not shown), which facilitates similar configurations of the various track sections 12 .
- the rods 22 are preferably vacuum metallized and range in length from approximately two inches to about six inches.
- Each rod 22 can be approximately 1 ⁇ 4′′ in diameter, so as to allow the balls 18 to roll unimpeded thereon (see FIGS. 1 and 2 ), where the balls can be approximately 1 ⁇ 2′′ in diameter.
- each of the joint members 16 includes a pair of spaced parallel cylindrical rods 26 joined together by a connector 28 .
- the joint member 16 is H-shaped, with the connector 28 attached to both rods 26 at their midpoints.
- the rods 26 and connector 28 are preferably monolithically formed, and may be fabricated from the same plastic as the rods 22 of the track sections 12 , or from any other suitable material.
- the rods 26 have a preferred diameter of approximately one quarter inch like that of the rods 22 , so as to allow the balls 18 to roll unimpeded thereon.
- Each rod 26 is provided with a pair of disks 30 , one embedded in each of its opposed ends.
- Each disk 30 is made from either a magnetic material or a magnetically conductive metal. Each disk 30 magnetically engages a corresponding one of the disks 24 on a mating one of the rods 22 , during construction of the roller coaster assembly 10 . More particularly, three combinations are possible when mating one of the rods 22 having the disk 24 and one of the rods 26 having the disk 30 : (1) the disk 24 is made of magnetic material and the disk 30 is made of magnetically conductive metal; (2) the disk 24 is made of magnetically conductive metal and the disk 30 is made of magnetic material, or; (3) both the disk 24 and the disk 30 are made of magnetic material.
- the mating rods 22 , 26 and their respective magnetic disks 24 , 30 must be arranged so as to maintain proper polarity between the magnetic disks 24 , 30 (i.e., N to S or vice versa).
- the connector 28 is flat and thin, and engages a lower surface of the rods 26 .
- the connector 28 is positioned away from the surface of the rods 26 on which the balls 18 roll.
- connector 28 can be positioned away from the inside upper quarter of the rods 26 , the surfaces on which the ball 18 rolls.
- the connector 28 is formed this way so as not to impede the balls 18 when rolling on the rods 26 of the joint member 16 .
- a ball 18 is shown in phantom lines rolling along the joint member 16 without contacting the connector 28 .
- connector 28 could be connected to rods 26 in any number of ways and could extend in any number of shapes.
- connectors shaped as an arch could be affixed to the lowermost point of each rod 26 so as not to occupy any of the space between the rods 26 .
- each of the joint members 16 includes a C-shaped cuff member 32 that extends outwardly from one of the rods 26 .
- Each of the cuff members 32 is dimensioned so as to removably engage a corresponding one of the vertical supports 14 . More particularly, the cuff member 32 is sized and shaped so as to be clipped onto a vertical support 14 to maintain the desired position of the joint member 16 and its associated track sections 12 , during operation of the roller coaster assembly 10 .
- the vertical supports 14 may include guide markings thereon for indicating where to attach one of the cuff members 32 , so as to aid in construction.
- the cuff members 32 are utilized throughout the roller coaster assembly 10 to suspend the track sections 12 between the successive vertical supports 14 , as illustrated in FIGS. 1 and 2 .
- each of the vertical supports 14 has an upper end 34 and a lower end 36 .
- the C-shaped cuff member 32 engages the vertical supports 14 intermediate to the upper and lower ends 34 , 36 thereof (see FIG. 5 ).
- the lower end 36 of each of the vertical supports 14 removably engages a base 38 , which has a plurality of upwardly-extending tubes 40 .
- the tubes 40 are dimensioned so as to have a diameter slightly larger than that of the lower end 36 of each of the vertical supports 14 , so that a secure friction fit is attained when the lower end 36 is inserted into one of the tubes 40 .
- the upper ends 34 of the vertical supports may removably support decorative elements, such as a flag 42 , and/or functional elements, such as a sensor 44 (see FIGS. 1 and 2 ), the purpose of which will be discussed hereinafter.
- the vertical supports 14 are made of clear or translucent plastic, and preferably contain a plurality of LED lights 46 to illuminate the roller coaster assembly 10 for an enhanced aesthetic experience, as shown in FIGS. 5 and 6 .
- the lift track assembly 20 includes an elongate, inclined housing 48 with a top roller 50 and a bottom roller 52 positioned at opposed ends thereof.
- the top roller 50 is positioned adjacent to, or attached to, one of the track sections 12 positioned at the top T of the roller coaster assembly 10 .
- the top roller 50 is preferably barbell-shaped, having a center portion 51 and two side portions 53 on either side thereof (see FIG. 7A ), the purpose of which will be discussed hereinafter.
- the center and side portions 51 , 53 are substantially cylindrical, and the diameter of the side portions 53 is greater than that of the center portion 51 .
- the bottom roller 52 which has a similar barbell shape, engages a C-shaped support 54 at the bottom B of the roller coaster assembly 10 and is positioned adjacent another of the track sections 12 positioned proximate the C-shaped support 54 .
- An endless belt 56 is contained within the housing 48 and is trained over the top and bottom rollers 50 , 52 .
- a battery-operated motor (not shown) contained within the housing 48 drives the rollers 50 , 52 to move the belt 56 in a clockwise direction, as viewed in FIG. 7 .
- Magnets 58 are affixed to the center of the interior surface of the belt 56 , the magnets 58 being narrower than the belt 56 .
- the belt 56 travels under, and in a plane substantially parallel to, an inclined top surface 59 of the housing 48 on which the balls 18 travel.
- the inclined top surface 59 is preferably made of a thin layer of non-magnetically conductive material with low friction-producing properties, such as a smooth plastic.
- the magnets 58 attract the balls 18 through the belt 56 and secure them to the center of the inclined top surface 59 as the balls 18 are conveyed from the bottom B to the top T of the roller coaster assembly 10 with a sliding motion (see arrows A and B in FIG. 7 ). This creates the illusion that the balls 18 are independently rolling up the stationary inclined top surface 59 .
- the roller coaster assembly 10 further includes special track sections or elements, such as a “loop-the-loop” 60 , a ball drop 62 , and a full loop 64 .
- special track sections and elements could include trampolines, bridges, and pendulums. These special track sections may be included with the roller coaster assembly 10 , or made available in an “expansion set” package for purchase and use at a later time.
- the rods that comprise the special track sections or elements have disks embedded in each of their ends like the disks 24 of rods 22 (i.e., they are made of either a magnetic material or a magnetically conductive metal), so that they may engage the respective disks 30 embedded in the corresponding ends of the rods 26 of mating joint members 16 .
- the roller coaster assembly 10 is also provided with an audiovisual system which includes a master controller 66 , a series of the sensors 44 (only one of the sensors 44 being shown being FIGS. 1 and 2 for illustrative clarity), and a plurality of output devices (not shown in FIGS. 1 and 2 , but to be described below).
- the audiovisual system is designed to introduce an array of dynamic audiovisual features to further enhance the use and operation of the roller coaster assembly 10 .
- the controller 66 is electronically programmed with voice and music samples and sound effects.
- the controller 66 preferably incorporates a “flash” memory so as to accept and store additional samples and sound effects from Internet downloads and other sources, such as MP3 and other digital media players.
- the sensors 44 are affixed to the track sections 12 and/or to the vertical supports 14 at various locations on the roller coaster assembly 10 .
- Each sensor 44 preferably corresponds to a predetermined musical or sound element in the controller 66 such as, but not limited to, rhythm, melody, riffs, voice, and sound effects.
- the sensors 44 are triggered by the movement of the balls 18 rolling along an adjacent track section 12 .
- the sensors 44 transmit signals to the controller 66 , which in turn activates an audio output device 68 (not shown) connected to the controller 66 , whereupon the audio output device 68 plays one or more of the programmed voice or music samples or sound effects.
- the controller 66 can control the speed of the lift track assembly 20 , which can determine the frequency by which balls are placed on the track assembly 10 , and the frequency by which the balls pass the sensors.
- FIG. 8 is a schematic diagram of the audiovisual system components of the roller coaster assembly 10 .
- Each sensor 44 is programmed to activate at least one sample or sound effect (via the controller 66 ) when triggered by the motion of the ball 18 . The speed and tempo of the balls 18 also determines which musical or sound element is played. Once triggered, the sensor 44 activates the controller 66 , which in turn plays the programmed sample or sound effect through the audio output device 68 , which may be a speaker, for example.
- a visual element such as a graphic display, animation sequence or video clip, may also be programmed into the controller 66 for playing in response to signals from the sensors 44 .
- the sensor 44 transmits a signal to the controller 66 when triggered by the motion of the balls 18 , whereupon the controller 66 plays a programmed visual element on an attached video output device 70 .
- the video output device 70 may be a video monitor or a computer screen, for example.
- Construction of the roller coaster assembly 10 may begin by connecting the disks 24 on proximate ends of the rods 22 of one of the track sections 12 to the respective disks 30 on the corresponding ends of the rods 26 of one of the joint members 16 .
- at least one of the mating disks 24 , 30 is made of a magnetic material, and the other one is either made of a magnetically conductive metal, or is also made of a magnetic material.
- Another of the track sections 12 may then be similarly connected to the opposite proximate ends of the rods 26 of the same joint member 16 (see FIGS. 1 and 2 ).
- One of the special track sections or elements e.g., the “loop-the-loop” 60 , the ball drop 62 , or the full loop 64 ) may be connected to one of the joint members 16 in a similar fashion.
- the interconnected track sections 12 are then suspended by way of clipping each of the cuff members 32 of the joint members 16 onto a respective vertical support 14 at a point intermediate the upper and lower ends 34 , 36 of the vertical support 14 (the lower ends 36 of the vertical supports 14 should already have been secured within the respective tubes 40 of the bases 38 at this time).
- the top and bottom rollers 50 , 52 of the lift track assembly 20 may then be positioned adjacent to, or attached to the track sections 12 suspended at the top T and bottom B of the roller coaster assembly 10 , respectively (see FIGS. 1, 2 , and 7 ).
- the interchangeability of the various structural elements allows a user to create many different coaster configurations of the roller coaster assembly 10 .
- each of the sensors 44 is secured to one of the track sections 12 or to one of the vertical supports 14 .
- the controller 66 , the audio output device 68 and the video output device 70 are positioned proximate the assembled structural elements, within signal transmission range of the plurality of the sensors 44 (see FIGS. 1 and 2 ).
- the power source(s) for the controller 66 , the sensors 44 , the audio output device 68 , the video output device 70 , and the LED lights 46 is/are activated.
- the battery-powered internal motor of the lift track assembly 20 is started, which rotates the top and bottom rollers 50 , 52 (as indicated by arrows C in FIG. 7 ), moving the belt 56 and the magnets 58 affixed thereto in a clockwise direction, as viewed in FIG. 7 .
- the balls 18 are attracted by the magnets 58 and are dragged onto the inclined top surface 59 of the housing 48 , as indicated by arrow A in FIG. 7 .
- the belt 56 conveys, or slides the magnetically-engaged balls 18 upwardly on the inclined top surface 59 towards the top roller 50 , as indicated by arrow B in FIG. 7 .
- the magnets 58 pass over the center portion 51 of the top roller 50 , while opposite edge portions of the belt 56 ride on the side portions 53 of the top roller 50 (see FIG. 7A ).
- the belt 56 and magnets 58 begin a descent towards the bottom roller 52 .
- the balls 18 reach the top T of the roller coaster assembly 10 and roll onto the adjacent track section 12 , thereby separating the balls 18 from the lift track assembly 20 . Due to gravitational force, the balls 18 then descend along the track sections 12 , as indicated by arrow D in FIG. 7 .
- the balls 18 trigger the sensors 44 , which in turn transmit signals to the controller 66 and play sound samples and effects and/or visual effects and video clips on the audio and video output devices 68 , 70 , respectively.
- the balls 18 negotiate the special track sections along the circuit of the roller coaster assembly 10 to loop, drop, or engage in other unusual movement, further enhancing the visual display. Once the balls 18 complete the circuit, they return to the bottom roller 52 of the lift track assembly 20 , whereupon the circuit may be repeated.
- the present invention provides numerous advantages over conventional toy roller coaster assemblies discussed above. For instance, the inclusion of LED lights 46 and the audiovisual system enhance the aesthetic appearance of the roller coaster assembly 10 , and add a sonic/musical dimension to the action of the balls 18 , making it more attractive to children.
- Another advantage of the present invention is the ability of the controller 66 to mix and match signals from the sensors 44 to an exhaustive selection of voice and song samples, sound effects, graphic displays, animation sequences, and video clips, all of which may be programmed into the controller 66 .
- the extensive variety of audiovisual outputs, combined with the many possible structural configurations make possible a virtually infinite number of variations and combinations of the sight, sound, and operation of the roller coaster assembly 10 .
- FIG. 9 illustrates a toy roller coaster assembly 100 according to another embodiment of the present invention.
- assembly 100 includes various structural elements including a plurality of track sections 120 , a plurality of columnar vertical supports 140 , and a plurality of joint members 160 , which connect the track sections 120 to each other and to the vertical supports 140 .
- a plurality of metal marbles or balls 180 that removably engage the track sections 120 .
- a lift track assembly 200 vertically conveys the balls 180 from the lowest level, or bottom B, of the roller coaster assembly 100 to the highest level, or top T, of the roller coaster assembly 100 .
- lift track assembly 200 lifts the balls 180 vertically straight up, in a direction perpendicular to the horizontal surface on which the assembly 100 sits.

FIGS. 1 and 2 illustrate a toyroller coaster assembly 10 constructed from multiple basic structural elements; namely, a plurality oftrack sections 12, a plurality of columnarvertical supports 14, and a plurality ofjoint members 16, which connect thetrack sections 12 to each other and to thevertical supports 14. Also included is a plurality of metal marbles orballs 18 that removably engage thetrack sections 12. Alift track assembly 20 vertically conveys theballs 18 from the lowest level, or bottom B, of theroller coaster assembly 10 to the highest level, or top T, of theroller coaster assembly 10. - Referring now to
FIGS. 3A and 3B , each of thetrack sections 12 comprises a pair ofcylindrical rods 22 which are spaced in a parallel formation, so as to allow theballs 18 to roll thereon. Therods 22 are preferably made from a plastic material. Eachrod 22 includes adisk 24 embedded in each of its opposed ends, the purpose of which will be discussed hereinafter. Eachdisk 24 is made from either a magnetic material or a magnetically conductive metal. Therods 22 are pre-formed to be straight (seeFIG. 3A ), curved (seeFIG. 3B ), or looped (not shown), which facilitates similar configurations of thevarious track sections 12. Therods 22 are preferably vacuum metallized and range in length from approximately two inches to about six inches. Eachrod 22 can be approximately ¼″ in diameter, so as to allow theballs 18 to roll unimpeded thereon (seeFIGS. 1 and 2 ), where the balls can be approximately ½″ in diameter. - Referring now to
FIGS. 4 and 4 A, each of thejoint members 16 includes a pair of spaced parallelcylindrical rods 26 joined together by aconnector 28. As illustrated inFIG. 4 , thejoint member 16 is H-shaped, with theconnector 28 attached to bothrods 26 at their midpoints. Therods 26 andconnector 28 are preferably monolithically formed, and may be fabricated from the same plastic as therods 22 of thetrack sections 12, or from any other suitable material. Therods 26 have a preferred diameter of approximately one quarter inch like that of therods 22, so as to allow theballs 18 to roll unimpeded thereon. Eachrod 26 is provided with a pair of disks 30, one embedded in each of its opposed ends. Each disk 30 is made from either a magnetic material or a magnetically conductive metal. Each disk 30 magnetically engages a corresponding one of thedisks 24 on a mating one of therods 22, during construction of theroller coaster assembly 10. More particularly, three combinations are possible when mating one of therods 22 having thedisk 24 and one of therods 26 having the disk 30: (1) thedisk 24 is made of magnetic material and the disk 30 is made of magnetically conductive metal; (2) thedisk 24 is made of magnetically conductive metal and the disk 30 is made of magnetic material, or; (3) both thedisk 24 and the disk 30 are made of magnetic material. In the third combination (i.e., the magnetic disk-to-magnetic disk combination), themating rods magnetic disks 24, 30 must be arranged so as to maintain proper polarity between themagnetic disks 24, 30 (i.e., N to S or vice versa). - As shown in
FIG. 4B , theconnector 28 is flat and thin, and engages a lower surface of therods 26. In other words, theconnector 28 is positioned away from the surface of therods 26 on which theballs 18 roll. For example, when viewed in a longitudinal cross-section of therods 26,connector 28 can be positioned away from the inside upper quarter of therods 26, the surfaces on which theball 18 rolls. Theconnector 28 is formed this way so as not to impede theballs 18 when rolling on therods 26 of thejoint member 16. To illustrate this structural feature, aball 18 is shown in phantom lines rolling along thejoint member 16 without contacting theconnector 28. In addition to configuration ofFIGS. 4A and 4B ,connector 28 could be connected torods 26 in any number of ways and could extend in any number of shapes. For example, connectors shaped as an arch could be affixed to the lowermost point of eachrod 26 so as not to occupy any of the space between therods 26. - Referring again to
FIGS. 4 and 4 A, each of thejoint members 16 includes a C-shapedcuff member 32 that extends outwardly from one of therods 26. Each of thecuff members 32 is dimensioned so as to removably engage a corresponding one of the vertical supports 14. More particularly, thecuff member 32 is sized and shaped so as to be clipped onto avertical support 14 to maintain the desired position of thejoint member 16 and its associatedtrack sections 12, during operation of theroller coaster assembly 10. The vertical supports 14 may include guide markings thereon for indicating where to attach one of thecuff members 32, so as to aid in construction. Thecuff members 32 are utilized throughout theroller coaster assembly 10 to suspend thetrack sections 12 between the successivevertical supports 14, as illustrated inFIGS. 1 and 2 . - Referring now to
FIGS. 1, 2 , 5, and 6, each of thevertical supports 14 has anupper end 34 and alower end 36. The C-shapedcuff member 32 engages thevertical supports 14 intermediate to the upper and lower ends 34, 36 thereof (seeFIG. 5 ). Furthermore, thelower end 36 of each of thevertical supports 14 removably engages abase 38, which has a plurality of upwardly-extendingtubes 40. Thetubes 40 are dimensioned so as to have a diameter slightly larger than that of thelower end 36 of each of thevertical supports 14, so that a secure friction fit is attained when thelower end 36 is inserted into one of thetubes 40. The upper ends 34 of the vertical supports may removably support decorative elements, such as aflag 42, and/or functional elements, such as a sensor 44 (seeFIGS. 1 and 2 ), the purpose of which will be discussed hereinafter. The vertical supports 14 are made of clear or translucent plastic, and preferably contain a plurality ofLED lights 46 to illuminate theroller coaster assembly 10 for an enhanced aesthetic experience, as shown inFIGS. 5 and 6 . - Referring now to
FIGS. 1, 2 , 7, and 7A, thelift track assembly 20 includes an elongate,inclined housing 48 with atop roller 50 and abottom roller 52 positioned at opposed ends thereof. Thetop roller 50 is positioned adjacent to, or attached to, one of thetrack sections 12 positioned at the top T of theroller coaster assembly 10. Thetop roller 50 is preferably barbell-shaped, having acenter portion 51 and twoside portions 53 on either side thereof (seeFIG. 7A ), the purpose of which will be discussed hereinafter. The center andside portions side portions 53 is greater than that of thecenter portion 51. Thebottom roller 52, which has a similar barbell shape, engages a C-shapedsupport 54 at the bottom B of theroller coaster assembly 10 and is positioned adjacent another of thetrack sections 12 positioned proximate the C-shapedsupport 54. Anendless belt 56 is contained within thehousing 48 and is trained over the top andbottom rollers housing 48 drives therollers belt 56 in a clockwise direction, as viewed inFIG. 7 .Magnets 58 are affixed to the center of the interior surface of thebelt 56, themagnets 58 being narrower than thebelt 56. Thebelt 56 travels under, and in a plane substantially parallel to, an inclinedtop surface 59 of thehousing 48 on which theballs 18 travel. The inclinedtop surface 59 is preferably made of a thin layer of non-magnetically conductive material with low friction-producing properties, such as a smooth plastic. Themagnets 58 attract theballs 18 through thebelt 56 and secure them to the center of the inclinedtop surface 59 as theballs 18 are conveyed from the bottom B to the top T of theroller coaster assembly 10 with a sliding motion (see arrows A and B inFIG. 7 ). This creates the illusion that theballs 18 are independently rolling up the stationary inclinedtop surface 59. - Now referring to
FIGS. 1 and 2 , theroller coaster assembly 10 further includes special track sections or elements, such as a “loop-the-loop” 60, aball drop 62, and afull loop 64. Other special track sections and elements could include trampolines, bridges, and pendulums. These special track sections may be included with theroller coaster assembly 10, or made available in an “expansion set” package for purchase and use at a later time. The rods that comprise the special track sections or elements have disks embedded in each of their ends like thedisks 24 of rods 22 (i.e., they are made of either a magnetic material or a magnetically conductive metal), so that they may engage the respective disks 30 embedded in the corresponding ends of therods 26 of matingjoint members 16. - Still referring to
FIGS. 1 and 2 , theroller coaster assembly 10 is also provided with an audiovisual system which includes amaster controller 66, a series of the sensors 44 (only one of thesensors 44 being shown beingFIGS. 1 and 2 for illustrative clarity), and a plurality of output devices (not shown inFIGS. 1 and 2 , but to be described below). The audiovisual system is designed to introduce an array of dynamic audiovisual features to further enhance the use and operation of theroller coaster assembly 10. More particularly, thecontroller 66 is electronically programmed with voice and music samples and sound effects. Thecontroller 66 preferably incorporates a “flash” memory so as to accept and store additional samples and sound effects from Internet downloads and other sources, such as MP3 and other digital media players. Thesensors 44 are affixed to thetrack sections 12 and/or to thevertical supports 14 at various locations on theroller coaster assembly 10. Eachsensor 44 preferably corresponds to a predetermined musical or sound element in thecontroller 66 such as, but not limited to, rhythm, melody, riffs, voice, and sound effects. Thesensors 44 are triggered by the movement of theballs 18 rolling along anadjacent track section 12. Once triggered, thesensors 44 transmit signals to thecontroller 66, which in turn activates an audio output device 68 (not shown) connected to thecontroller 66, whereupon theaudio output device 68 plays one or more of the programmed voice or music samples or sound effects. In an embodiment of the present invention, thecontroller 66 can control the speed of thelift track assembly 20, which can determine the frequency by which balls are placed on thetrack assembly 10, and the frequency by which the balls pass the sensors. - Reference is now made to
FIG. 8 , which is a schematic diagram of the audiovisual system components of theroller coaster assembly 10. Eachsensor 44 is programmed to activate at least one sample or sound effect (via the controller 66) when triggered by the motion of theball 18. The speed and tempo of theballs 18 also determines which musical or sound element is played. Once triggered, thesensor 44 activates thecontroller 66, which in turn plays the programmed sample or sound effect through theaudio output device 68, which may be a speaker, for example. - Still referring to
FIG. 8 , a visual element, such as a graphic display, animation sequence or video clip, may also be programmed into thecontroller 66 for playing in response to signals from thesensors 44. As in the production of the sample or sound effect described above, thesensor 44 transmits a signal to thecontroller 66 when triggered by the motion of theballs 18, whereupon thecontroller 66 plays a programmed visual element on an attachedvideo output device 70. Thevideo output device 70 may be a video monitor or a computer screen, for example. - Construction of the
roller coaster assembly 10 may begin by connecting thedisks 24 on proximate ends of therods 22 of one of thetrack sections 12 to the respective disks 30 on the corresponding ends of therods 26 of one of thejoint members 16. As previously described, at least one of themating disks 24, 30 is made of a magnetic material, and the other one is either made of a magnetically conductive metal, or is also made of a magnetic material. Another of thetrack sections 12 may then be similarly connected to the opposite proximate ends of therods 26 of the same joint member 16 (seeFIGS. 1 and 2 ). One of the special track sections or elements (e.g., the “loop-the-loop” 60, theball drop 62, or the full loop 64) may be connected to one of thejoint members 16 in a similar fashion. - The interconnected track sections 12 (and/or special track sections) are then suspended by way of clipping each of the
cuff members 32 of thejoint members 16 onto a respectivevertical support 14 at a point intermediate the upper and lower ends 34, 36 of the vertical support 14 (the lower ends 36 of thevertical supports 14 should already have been secured within therespective tubes 40 of thebases 38 at this time). The top andbottom rollers lift track assembly 20 may then be positioned adjacent to, or attached to thetrack sections 12 suspended at the top T and bottom B of theroller coaster assembly 10, respectively (seeFIGS. 1, 2 , and 7). The interchangeability of the various structural elements allows a user to create many different coaster configurations of theroller coaster assembly 10. - Once the structural elements of the
roller coaster assembly 10 have been interconnected as described above, the audiovisual system components may be set up. More particularly, each of thesensors 44 is secured to one of thetrack sections 12 or to one of the vertical supports 14. Thecontroller 66, theaudio output device 68 and the video output device 70 (some or all of which may be contained in one housing), are positioned proximate the assembled structural elements, within signal transmission range of the plurality of the sensors 44 (seeFIGS. 1 and 2 ). - In operation, the power source(s) for the
controller 66, thesensors 44, theaudio output device 68, thevideo output device 70, and the LED lights 46 is/are activated. The battery-powered internal motor of thelift track assembly 20 is started, which rotates the top andbottom rollers 50, 52 (as indicated by arrows C inFIG. 7 ), moving thebelt 56 and themagnets 58 affixed thereto in a clockwise direction, as viewed inFIG. 7 . Once on thetrack section 12 at the bottom B of theroller coaster assembly 10, theballs 18 are attracted by themagnets 58 and are dragged onto the inclinedtop surface 59 of thehousing 48, as indicated by arrow A inFIG. 7 . Thebelt 56 conveys, or slides the magnetically-engagedballs 18 upwardly on the inclinedtop surface 59 towards thetop roller 50, as indicated by arrow B inFIG. 7 . During such movement of thebelt 56, themagnets 58 pass over thecenter portion 51 of thetop roller 50, while opposite edge portions of thebelt 56 ride on theside portions 53 of the top roller 50 (seeFIG. 7A ). - Immediately after negotiating the
top roller 50, thebelt 56 andmagnets 58 begin a descent towards thebottom roller 52. Simultaneously, theballs 18 reach the top T of theroller coaster assembly 10 and roll onto theadjacent track section 12, thereby separating theballs 18 from thelift track assembly 20. Due to gravitational force, theballs 18 then descend along thetrack sections 12, as indicated by arrow D inFIG. 7 . During their descent along thetrack sections 12, thejoint member 16 and the other structural elements, theballs 18 trigger thesensors 44, which in turn transmit signals to thecontroller 66 and play sound samples and effects and/or visual effects and video clips on the audio andvideo output devices balls 18 negotiate the special track sections along the circuit of theroller coaster assembly 10 to loop, drop, or engage in other unusual movement, further enhancing the visual display. Once theballs 18 complete the circuit, they return to thebottom roller 52 of thelift track assembly 20, whereupon the circuit may be repeated. - It should be appreciated that the present invention provides numerous advantages over conventional toy roller coaster assemblies discussed above. For instance, the inclusion of
LED lights 46 and the audiovisual system enhance the aesthetic appearance of theroller coaster assembly 10, and add a sonic/musical dimension to the action of theballs 18, making it more attractive to children. - Another advantage of the present invention is the ability of the
controller 66 to mix and match signals from thesensors 44 to an exhaustive selection of voice and song samples, sound effects, graphic displays, animation sequences, and video clips, all of which may be programmed into thecontroller 66. The extensive variety of audiovisual outputs, combined with the many possible structural configurations make possible a virtually infinite number of variations and combinations of the sight, sound, and operation of theroller coaster assembly 10. - It will be understood that the embodiment described herein is merely exemplary, and that a person skilled in the art may make many variations and modifications without departing from the spirit and scope of the invention. Such variations, for example, include the sizes and materials of the various structural components of the
roller coaster assembly 10. Themagnets 58 affixed to thebelt 56 in thelift track assembly 20 may be embedded within thebelt 56 instead or on a side ofbelt 56 opposite to the side on which the magnets are shown inFIG. 7 . Additional structural and audiovisual features, including those not discussed in the foregoing detailed description, may be available in a compatible but separate expansion package or packages. Sound and/or video cards, amplifiers and other components may also be incorporated into the audiovisual system. These and all other such variations and modifications are intended to be included within the scope of the invention. -
FIG. 9 illustrates a toyroller coaster assembly 100 according to another embodiment of the present invention. As shown,assembly 100 includes various structural elements including a plurality oftrack sections 120, a plurality of columnarvertical supports 140, and a plurality ofjoint members 160, which connect thetrack sections 120 to each other and to the vertical supports 140. Also included is a plurality of metal marbles orballs 180 that removably engage thetrack sections 120. Alift track assembly 200 vertically conveys theballs 180 from the lowest level, or bottom B, of theroller coaster assembly 100 to the highest level, or top T, of theroller coaster assembly 100. In this embodiment,lift track assembly 200 lifts theballs 180 vertically straight up, in a direction perpendicular to the horizontal surface on which theassembly 100 sits. - Referring to
FIGS. 9 and 10 , each of thetrack sections 120 comprises a pair ofrods 220 that are spaced apart from each other in a parallel formation a distance sufficient to hold theballs 180 and allow theballs 180 to roll over and in between therods 220. The rods can be held together by at least one connecting member, such asend connector 280 orintermediate connector 281, as shown inFIG. 10 . Theconnectors rods 220 without obstructing the travel of aball 180 over therods 220. As shown best inFIG. 10 , in this embodiment, the upper surface ofconnector 280 in betweenrods 220 has the shape of a partial cylinder. The channel created by this partial cylinder enables aball 180 to pass over theconnector 280 without obstruction. Theconnectors rods 220 using other shapes and configurations, as described above with reference toconnector 28 ofFIGS. 4A and 4B . - In one implementation of the present invention, track
sections 120 are assembled magnetically, with at least one magnet or ferromagnetic element disposed at each end of a track section. Preferably, as shown inFIG. 10 , amagnet 240 is disposed at the end of eachrod 220. In this example,magnets 240 are cylindrical magnets and are embedded in the hollow bodies of theconnectors 280 that connect the ends ofrods 220.Covers 241 retain the magnets within thehollow connectors 280. - The
rods 220 are pre-formed in any number of shapes and sizes suitable for conveyingballs 180, including straight sections, curved sections, and circular or looped sections. Therods 220 are preferably made of plastic over which a thin layer of metal is deposited by vacuum metallization. A transparent topcoat can be applied over the metallic coating to improve its abrasion resistance and protect it against environmental influences, such as humidity. Therods 22 can range in length from approximately two inches to approximately six inches. Eachrod 22 can be, for example, ¼″ in diameter, which can accommodate an approximately ½″ diameter ball without impeding the ball. - In magnetically assembling
coaster assembly 100,track sections 120 can be connected directly to each other. Alternatively, tracksections 120 can be connected usingjoint members 160, which also enable the connection oftrack sections 120 tovertical supports 140 to achieve different elevations for each of thetrack sections 120. As shown inFIG. 10 , an exemplaryjoint member 160 includes two spaced apart projectingmembers 320 connected by aconnector 283. In this example, projectingmembers 320 are C-shaped so as to partially wrap around avertical support 140. These C-shapedmembers 320 can be configured to tightly snap aroundvertical supports 140 by an interference fit, to secure thejoint member 160 on thevertical support 140 without sliding down. - Alternatively or in addition to the interference fit, the C-shaped
members 320 can include aprojection 321 configured to engage cooperatingprojections 323 on a vertical support (as shown inFIG. 9 ). In this manner, the hook-shapedprojection 321 can hang on theprojections 323 of the vertical supports 140. Thevertical supports 140 can be generally rectangular in shape as shown inFIG. 9 , with pairs ofprojections 323 located at incremental elevations to enable a variety of configurations for supporting and joiningtrack sections 120. Eachvertical support 140 is removably connected to abase 380, which is of a dimension and stiffness suitable for supporting thevertical supports 140 upright along with the joinedtrack sections 120. - As shown in
FIG. 10 , ajoint member 160 magnetically couples twotrack sections 120. As such,joint member 160 can be magnetic or ferromagnetic, depending on the particular magnetic or ferromagnetic elements provided in the ends of thetrack sections 120. In one embodiment,joint member 160 provides ferromagnetic surfaces to which magnetic ends of thetrack sections 120 magnetically bond. To provide a superior bond, however,joint member 160 can contain at least one magnet. As shown inFIG. 10 ,magnets 284 can be disposed in the hollow body of theconnector 283, with acover 285 holding themagnets 284 withinconnector 283. Theconnector 283 ofjoint member 160 can be sized and shaped similarly to theconnectors 280 of thetrack sections 120, which provides continuous surfaces that enable a substantially seamless connection between the components, enabling aball 180 to roll over each component without obstruction. To provide the magnetic bond, the polarities of the magnets in thetrack sections 120 andjoint member 160 alternate, as shown inFIG. 10 .Joint member 160 may be fabricated from the same plastic astrack sections 120, or from any other suitable material. -
FIGS. 11A and 11B illustrate alift track assembly 200 according to an embodiment of the present invention. As shown,lift track assembly 200 rests on a base 201 from which it extends vertically upward.Balls 180 enter thelift track assembly 200 through aball separator assembly 202 and magnetically bond to magnets revolving within the assembly, which carry theballs 180 up theassembly 200 and deliver the balls to a highest track section 120 (seeFIG. 9 ). As shown in the exploded view ofFIG. 11B , this exemplarylift track assembly 200 includesmotorized pulleys 203, anendless belt 204 routed around thepulleys 203, a plurality ofmagnets 205 affixed to thebelt 204 bymagnet holders 206, belt housing covers 207, and assembly end caps 208.Magnet holders 206 are affixed to thebelt 204 by adhesive, for example. In turn,magnets 205 are affixed to the magnet holders by, for example, adhesive, injection molding, or an interference fit. Themagnets 205,magnet holders 206, andbelt 204, and the means by which they are fastened to each other, are flexible enough to travel around the radius of thepulleys 203. Alternatively, instead of usingseparate magnets 205, thebelt 204 itself could be made of a flexible magnetic material. In addition,belt 204 could be configured as described above in reference to the embodiments ofFIGS. 7 and 7 A. - Lift
track assembly 200 could operate withbelt 204 and itsmagnets 205 exposed. However, to provide the visually striking appearance ofballs 180 magically traveling up a vertical column, an embodiment of the present invention covers thebelt 204 with belt housing covers 207.Covers 207 can be made of a thin, smooth non-magnetic material that does not interfere with the magnetic coupling between the magnetic belt and the ferromagnetic balls, and enables theballs 180 to freely travel. By using a magnet and a ball (as opposed to some other toy vehicle), the ball freely rolls over the cover and contributes to the illusion that the toy object is rolling upward by itself. To complete the finished appearance ofassembly 200 and protect its moving parts,assembly 200 can also includeend caps 208. - An embodiment of the present invention provides a
ball separator 202 that controls the passage ofballs 180 ontolift track assembly 200. As shown in the exploded view ofFIG. 12 ,ball separator 202 includes a track section 1200, aball spacer 1206, aball separator magnet 1208, aball separator cap 1210, and aball arch 1212. Track section 1200 can be configured similarly to the track sections described above, including a pair of spaced apart rods joined by aconnector 1202, which has magnets for joining track section 1200 to other track sections or joint members. Track section 1200 is configured to slope down towards the bottom oflift track assembly 200. In this embodiment, track section 1200 has at its end opposite connector 1202 abase 1204 that is positioned near the bottom oflift track assembly 200.Base 1204 can attach to liftbase 201 to maintain a distance and alignment appropriate for magnetically transferringballs 180 fromball separator 202 to lifttrack assembly 200. - Proximate to the exit end of track section 1200, ball arch 1212 is connected to the pairs of rods of the track section 1200.
Ball arch 1212 spans the rods and is sized and shaped to lightly contact theballs 180 as they pass through the arch 1212. The friction created by this light contact slows the balls down and prevents them from bumping into each other and interfering with the transfer of balls onto thelift track assembly 200. The size, shape, and material of the ball arch 1212 can be adjusted to provide the friction appropriate for good operation of theball separator 202. - Beyond the arch 1212, ball spacer 1206 is pivotably connected to track section 1200 so that it can pivot into and out of the path of the balls, for example, pivoting from below, from the side, or from above the ball path. In this example, ball spacer 1206 pivots from below the rods and can rise into the path of the balls.
Ball spacer 1206 containsball separator magnet 1208 and is preferably biased (e.g., by a spring or by gravity) to remain below the rods. When a ferromagnetic ball passes over themagnet 1208, the magnetic attraction between the ball and themagnet 1208 lifts the projecting member of the ball spacer 1206 above the rods, which separates the ball from the other balls lined up behind the ball waiting to enter thelift track assembly 200. When thelift track assembly 200 pulls the ball off of theball separator 202, the ball spacer 1206 pivots back down, which removes the projecting member from the ball path and allows the next ball to pass over the rods and above themagnet 1208. This process then repeats for each ball. As shown inFIG. 12 ,ball separator 202 can include acap 1210 at its exit end for covering the ball spacer 1206 andmagnet 1208, and for providing a connection to thelift base 201. - Referring again to
FIG. 9 , toyroller coaster assembly 100 can include special track features such as a loop-the-loop 600, atrampoline 602, amagnetic U-turn 606, and amagnetic bridge 604. These components can be incorporated in the track sections ofassembly 100 and provided with magnetic couplings as described above fortrack sections 120. For example, as shown inFIG. 9 , atrack section 120 can include a pair of rods formed in afull loop 640. As another example, atrack section 120 can include a pair of rods having an integrally formedtrampoline 602, with the rods shaped to deliver a ball off of the rods, onto the trampoline, and then back onto the rods. In other words, the ball leaves the pair of rods, bounces on the trampoline, and lands back on a lower part of the pair of rods. The trampoline can be made of a thin elastic membrane, such as a sheet of rubber. -
FIG. 13 illustrates amagnetic bridge 604 according to an embodiment of the present invention. As shown,magnetic bridge 604 includes two pairs ofrods 1300 connected by a singlemagnetic rod 1302. Twobrackets 1304 supportmagnetic rod 1302 over the pairs ofrods 1300, preferably centered longitudinally in between the rods.Brackets 1304 can be in the shape of an arch or half of an arch, under whichballs 180 can pass.Brackets 1304 each include at least onemagnet 1306, retained inside the housings of thebrackets 1304 by acap 1308. Themagnets 1306 transfer magnetism to therod 1302 to makerod 1302 magnetic, so that theferromagnetic balls 180 adhere torod 1302. As shown inFIG. 13 , the open ends of the pairs ofrods 1300 are curved away fromrod 1302, which facilitates the transfer of theballs 180 to and from therod 1302. Thus, for example, looking at a ball traveling through themagnetic bridge 604 ofFIG. 13 from left to right, a ball passes underneath thebracket 1306 on the left, magnetically adheres to and rolls along the rod 1302 (as shown inFIG. 9 , for example), drops off of therod 1302 at thebracket 1306 on the left, and lands on the pairs ofrods 1300 on the right, continuing to roll along the track assembly. Alternatively, instead of having a rod magnetically charged by separate magnets,rod 1302 itself could be made of magnetic material. -
FIG. 14 illustrates an exploded view of themagnetic U-turn 606 shown inFIG. 9 , according to an embodiment of the present invention. As shown,magnetic U-turn 606 includes arod section 1400, amagnet 1402, anupper connector 1404, alower connector 1406, and caps 1408.Rod section 1400 can include a pair of spaced apart, U-shaped rods, held together by amagnet housing 1410.Magnet 1402 is disposeinside magnet housing 1410.Lower connector 1406 attaches to the lower ends of the rods and provides a cover overmagnet housing 1410.Upper connector 1404 attaches to the upper ends of the rods. - Upper and
lower connectors 1406 can include magnetic or ferromagnetic components for connectingmagnetic U-turn 606 to other track sections as described above.Caps 1408 can seal such components insideconnectors Connectors magnetic U-turn 606 tovertical supports 140, such as the C-shapedmembers 1412 shown inFIG. 9 . - In operation,
magnetic U-turn 606 transfers a ball traveling on an upper track section in one direction, to a lower track on which the ball travels in the opposite direction. As the ball travels onto therod section 1400, themagnet 1402 holds the ball against the rods as ball rolls around the U-turn. When the ball rolls around to the lower part of therod section 1400, the magnetic attraction diminishes and allows the ball to drop from the rods while it is still traveling in generally the reverse direction. The ball drops from the lower part of therod section 1400 and lands on a lower track section (such assection 1414 inFIG. 9 ) to continue on in the track assembly. In this manner, U-turn 606 provides a visually interesting effect in which the ball appears to steer itself around the U-turn to an upside down position, and then jump from underneath the U-turn to the next track section. - As shown in
FIG. 9 , an embodiment of the toyroller coaster assembly 100 can include acontroller 250, which can control the speed oflift track assembly 200 and can provide audiovisualeffects using sensors 251, as described above in reference tocontroller 66 ofFIG. 1 .Controller 250 can control the pace of the balls and can generate audiovisual effects in response toballs passing sensors 251. A user can also customize the timing and content of the effects by placing sensors at different locations throughout theassembly 100, and by supplying personal digital media content to thecontroller 250. For example, a user can download digital music to a flash memory in thecontroller 250, or can plug an MP3 player or other digital music player into thecontroller 250. - In one aspect of the invention,
controller 250 plays background music while theassembly 100 is in operation, with thelift track assembly 200 revolving and lifting balls to the highest track section. The user can then add beats or other musical effects to the background music by placingsensors 251 along the track, which activate the beat or effect when a ball passes by. The user can change the background music and the music effects using thecontroller 250. Thecontroller 250 can also provide a “shuffle mode” in which the user's musical settings are randomly reconfigured. -
Controller 250 can include an integrated speaker, a headphone jack and headphones, lights, and a display panel, for generating the audiovisual effects.Sensors 251 can be magnetic, optical (e.g., infrared), or mechanical (e.g., spring lever switch), or can use any other means appropriate for detecting the passing balls. - In a further aspect of the present invention, a toy roller coaster assembly includes track sections formed from bendable, repositionable rods. In this manner, a user can create any desired track configuration as long as two corresponding pairs of rods are shaped to adequately carry the balls. The bendable rods can be separate pieces that are joined by connectors (such as the embodiment of
FIGS. 3A-4B ) or can include integral connectors that enable the bending of an entire track section (such as in the embodiment ofFIGS. 9 and 10 ). For example, with integral connectors, the entire track section can be twisted into helical shapes. To enable repositioning, the rods of this embodiment can be made of a material that flexes and bends, yet maintains sufficient sturdiness and rigidity in its new position. - In a further aspect of the present invention, the
balls 180 are magnetic in addition to or instead of the components of the toy roller coaster assembly. For example, in one embodiment, a lift track assembly could provide a ferromagnetic belt that attracts and carries magnetic balls. As another example, magnetic balls could adhere to the ferromagnetic rods of a track section. - The foregoing disclosure of the preferred embodiments of the present invention has been presented for purposes of illustration and description.
