- the crank assembly 22 may be free to rotate such that the foot pedals 34 , 36 can move along reciprocating paths that include circular motion.
- a change in the angular position of the frame 14 with respect to the stationary horizontal base 12 also changes the angle of these reciprocating paths that incorporate circular motion.
- Such changes in the angles of the reciprocating paths can also change the workout such that the workout becomes more difficult, easier, or targets different muscle groups.
- the stationary horizontal base 12 may remain in the same angular orientation when the frame 14 pivots with respect to the stationary horizontal base 12 . In such an example, the angular orientation of the stationary horizontal base 12 remains constant regardless of the angle of the frame 14 .
- the length of the stationary horizontal base 12 may be aligned with a length of the function portion of the exercise machine 10 . As the frame 14 pivots with respect to the stationary horizontal base 12 a distance between a rear portion of the exercise machine's functional portion and a rear portion of the stationary horizontal base 12 may increase or decrease depending on the direction that the frame 14 is pivoting. In some examples when the frame 14 is pivoted upwards, the entire weight of the functional portion of the exercise machine (e.g. minus the weight of the stationary horizontal base 12 ) is loaded to pivot connections that are in the front portion of the exercise machine 10 .

Abstract
Description
- This application claims priority to provisional Patent Application No. 61/922,660 titled “Selective Angular Positioning of the Crank of an Elliptical” filed Dec. 31, 2013. This application is herein incorporated by reference for all that it discloses.
- Aerobic exercise is a popular form of exercise that improves one's cardiovascular health by reducing blood pressure and providing other benefits to the human body. Aerobic exercise generally involves low intensity physical exertion over a long duration of time. Typically, the human body can adequately supply enough oxygen to meet the body's demands at the intensity levels involved with aerobic exercise. Popular forms of aerobic exercise include running, jogging, swimming, and cycling among other types of aerobic exercise. In contrast, anaerobic exercise typically involves high intensity exercises over a short duration of time. Popular forms of aerobic exercise include strength training and short distance running.
- Many choose to perform aerobic exercises indoors, such as in a gym or their home. Often, a user will use an aerobic exercise machine to have an aerobic workout indoors. One such type of aerobic exercise machine is an elliptical exercise machine, which often includes foot supports that move in reciprocating directions when moved by the feet of a user. Often, the foot supports will be mechanically linked to arm levers that can be held by the user during the workout. The arm levers and foot supports move together and collectively provide resistance against the user's motion during the user's workout. Other popular exercise machines that allow a user to perform aerobic exercises indoors include treadmills, rowing machines, stepper machines, and stationary bikes to name a few.
- One type of elliptical exercise machine is disclosed in U.S. Pat. No. 8,047,968 issued to Brian C. Stewart. In this reference, an apparatus and method permitting a user to perform simulated climbing and full body exercise is provided. The design includes a frame and a pair of lever arms and a pair of foot platforms and a torso support. The frame is configured to place the operator's center of gravity in a position of falling away from the frame, lever arms, foot platforms and providing a torso support enabling the operator to be supported by hanging from the hands and supported by the feet and torso support. The frame may be rotated through varying angles from vertical permitting the operator's center of gravity to fall away from the frame and allow the operator to hang away from the frame further enhancing the climbing experience. Other types of elliptical exercise machines are described in U.S. Pat. No. 7,618,350 issued to William T. Dalebout and U.S. Patent Publication No. 2012/0190508 issued to Scott Watterson.

FIG. 7 illustrates a cross sectional view of an example of a frame in accordance with the present disclosure. - Throughout the drawings, identical reference numbers designate similar, but not necessarily identical, elements.
- An exercise machine, such as an elliptical exercise machine, includes foot pedals that are mechanically linked together. Such foot pedals are often mechanically linked to arm supports that move with the foot pedals of the elliptical exercise machine. Thus, when any of either the foot pedals or either of the arm supports move, each of the foot pedals and each of the arm supports also move. As a result, when a user moves any of these components, each of these components move together.
- A user can stand on the foot pedals and move his or her feet along a reciprocating path traveled by the foot pedals while moving the arm supports back and forth. A user gets an increased workout when the collective movement of the foot pedals and arm supports is resisted. Often, the resistance to the foot pedal's movement is adjustable. Such resistance may be achieved through any appropriate mechanism. In some examples, a magnetic unit is positioned near a flywheel such that a magnetic force of the magnetic unit resists the movement of the flywheel. To adjust the magnetic resistance force, the magnetic unit may be moved closer to or away from the flywheel. In alternative examples, the magnetic force is proportional to electrical energy applied to the magnetic unit, and the strength of the magnetic field can be adjusted by applying a different level of electrical energy to the flywheel. In yet other examples, tensioning units, compression pads, pneumatic mechanisms, other mechanisms, or combinations thereof are adjusted to change the resistance.
- In lieu of or in addition to the resistance mechanism described above, a workout of an exercise machine may be changed by adjusting an incline of the paths traveled by the foot pedals. The principles described in the present disclosure include an exercise machine where the frame of the exercise machine can pivot with respect to a stationary horizontal base of the exercise machine. As a result, each of the components that are attached to the frame will pivot with the frame. For example, if the flywheel, foot pedals, arm supports, and other components of the exercise machine are attached to the frame, the flywheel, foot pedals, and arm supports also move as the frame pivots. As the frame pivots with respect to the stationary horizontal base, the angle between the stationary horizontal base and the frame changes. The flywheel, foot pedals, and arm supports are moved to corresponding angles with the frame. In situations where the resulting angle causes an increased incline between the frame and the stationary horizontal base, the user may experience an increase in the difficulty of the workout. In some examples, the user may desire to change the incline angle to target different muscle groups.
- For purposes of the present disclosure, the term “resistance mechanism” includes those components that directly interact to cause an added degree of resistance during the user's workout. For example, a resistance mechanism may include a flywheel when the exercise machine has components that can adjustably impose resistance to the movement of the flywheel, such as imposing a magnetic force on the flywheel to prevent the flywheel's rotation. The flywheel is included in the resistance mechanism when other components interact with the flywheel to directly resist the flywheel's movement. For example, braking pads, tensioning elements, fan blades, or other components can be used to directly resist the movement of the flywheel. In such examples, both the flywheel and the components interact to adjustably resist the movement of the flywheel and are included as part of the resistance mechanism.
- For purposes of the present disclosure, the term “stationary exercise machine” include exercise machines that do not propel the exercise machine or otherwise change a location of the user of the exercise machine based on the effort exerted by the user during his or her workout. Such stationary exercise machines may change the incline of the machine or otherwise change the location of the machine based on motors, drivers, actuators, hydraulic systems, or other mechanism that operate independent of the user's workout performance. For example, such functions may be operable by commands given by the user, such as selecting an option through a control module of the stationary exercise machine.
- Particularly, with reference to the figures,
FIGS. 1-2 depict an example of anexercise machine 10, such as an elliptical exercise machine. In the example ofFIG. 1 , the exercise machine is a stationary exercise machine, however, other types of exercise machines may be used in accordance with the principles described herein. Theexercise machine 10 includes a base 12 that is attached to aframe 14 at a firstframe pivot connection 11 and a secondframe pivot connection 13. Alower portion 15 of theframe 14 includes ahousing 16 that supports afirst flywheel 18 and asecond flywheel 20. Thefirst flywheel 18 and thesecond flywheel 20 are attached to one another through acrank assembly 22. Thecrank assembly 22 includes acrank arm 24 that is attached to afirst shaft 26 that is connected to thefirst flywheel 18 on afirst end 28 and attached to asecond shaft 30 that is connected to thesecond flywheel 20 at asecond end 32. - The stationary
horizontal base 12 may be any appropriate base in accordance with the principles described in the present disclosure. In some examples, the stationaryhorizontal base 12 is flat and has a center of gravity that is close to a floor or other type of foundation upon which theexercise machine 10 resides. The stationaryhorizontal base 12 may be made of a continuous beam of metal with a curvature such that multiple portions of the continuous beam are positioned to make the first and secondframe pivot connections lower portion 15 of theframe 14. In other examples, cross bars connect the multiple portions of the stationaryhorizontal base 12. In some examples, the frame includes just horizontally positioned beams that are aligned with the floor or another type of foundation. In yet other examples, the stationaryhorizontal base 12 may include a vertical support member that is intended to carry a vertical load. In some examples, the first and secondframe pivot connections midsection 17 or rear section of the horizontally positioned beams of the stationaryhorizontal base 12. - The
first shaft 26 is attached to an underside of afirst track 33 that supports afirst foot pedal 34, and thesecond shaft 30 is attached to an underside of asecond track 35 that supports asecond foot pedal 36. Thecrank assembly 22 is shaped such that thefirst shaft 26 and thesecond shaft 30 follow reciprocating paths. Consequently, thefirst foot pedal 34 follows the path of thefirst shaft 26, and thesecond foot pedal 36 follows the path of thesecond shaft 30. As a user stands on thefirst foot pedal 34 and thesecond foot pedal 36 for a workout, the user's feet also follow the reciprocating paths of thefirst foot pedal 34 and thesecond foot pedal 36. In some examples, thefirst foot pedal 34 is slidable along the length of thefirst track 33. Likewise, thesecond foot pedal 36 may be slidable along the length of thesecond track 35. Thus, in some examples, thefirst foot pedal 34 and thesecond foot pedal 36 are movable in multiple directions: down the length of the tracks and with the reciprocating paths defined by the travel of thefirst shaft 26 and thesecond shaft 30. - The
first foot pedal 34 is connected to afirst arm support 38 through a firstmechanical linkage 40, and thesecond foot pedal 36 is connected to asecond arm support 42 through a secondmechanical linkage 44. Thefirst arm support 38 is connected to theframe 14 at a firstarm pivot connection 46, and thesecond arm support 42 is connected to theframe 14 at a secondarm pivot connection 48. In the example ofFIGS. 1-2 , the firstmechanical linkage 40 includes afirst bottom section 50 of thefirst arm support 38 connected to a firstfar end 52 of thefirst track 33 at a first joint 54. Likewise, the secondmechanical linkage 44 may include asecond bottom section 56 of thesecond arm support 42 connected to a secondfar end 58 of thesecond track 35 at a second joint 60. - A
control module 62 is connected to across bar 64 that connects afirst post 66 of theframe 14 to asecond post 68 of theframe 14. Thecontrol module 62 may includemultiple buttons 70, adisplay 72, a cooling vent, a speaker, another device, or combinations thereof. Thecontrol module 62 can include a resistance input mechanism 76 that allows the user to control how much resistance is applied to the movement of thefirst foot pedal 34, thesecond foot pedal 36, thefirst arm support 38, and thesecond arm support 42. Thecontrol module 62 may also provide the user with an ability to control other functions of theexercise machine 10. For example, thecontrol module 62 may be used to control a level of a climate control, to control an incline angle between theframe 14 and the stationaryhorizontal base 12, to control speaker volume, to select a preprogrammed workout, to control entertainment through the speakers of thedisplay 72 of thecontrol module 62, to monitor a health parameter of the user during a workout, to communicate with a remote trainer or computer, to control other functions, or combinations thereof. -
FIGS. 3-4 illustrate an example of theexercise machine 10 with aframe 14 rotated up with respect to the stationaryhorizontal base 12. In this example, the first andsecond flywheels second tracks second foot pedals horizontal base 12 as theframe 14 forms a new angle with the stationaryhorizontal base 12. In some embodiments, the entire functional portion of theexercise machine 10 rotates about arotational axis 78 formed by the first and secondframe pivot connections frame 14 to reach a new incline. - The change in angle allows the user to change the difficulty of the workout and/or target different muscle groups by changing the user's incline with respect to the floor or other foundation upon which the
exercise machine 10 resides. The angle change drives an incline change. Thus, in examples where the user is positioned on thefoot pedals frame 14 pivots about the first and secondframe pivot connections foot pedals tracks exercise machine 10 becoming more aligned with a gravitational pull. Thus, an increased amount of gravitational resistance is imposed on the user. - In some examples, the first and
second foot pedals 34. 36 are movably attached to the first andsecond tracks foot pedals tracks crank assembly 22 can be locked so that thefoot pedals tracks tracks foot pedals tracks frame 14 and the stationaryhorizontal base 12, a workout that includes sliding thefoot pedals tracks - In some situations, the
foot pedals tracks foot pedals crank assembly 22 may be free to rotate such that thefoot pedals frame 14 with respect to the stationaryhorizontal base 12 also changes the angle of these reciprocating paths that incorporate circular motion. Such changes in the angles of the reciprocating paths can also change the workout such that the workout becomes more difficult, easier, or targets different muscle groups. - The stationary
horizontal base 12 may remain in the same angular orientation when theframe 14 pivots with respect to the stationaryhorizontal base 12. In such an example, the angular orientation of the stationaryhorizontal base 12 remains constant regardless of the angle of theframe 14. The length of the stationaryhorizontal base 12 may be aligned with a length of the function portion of theexercise machine 10. As theframe 14 pivots with respect to the stationary horizontal base 12 a distance between a rear portion of the exercise machine's functional portion and a rear portion of the stationaryhorizontal base 12 may increase or decrease depending on the direction that theframe 14 is pivoting. In some examples when theframe 14 is pivoted upwards, the entire weight of the functional portion of the exercise machine (e.g. minus the weight of the stationary horizontal base 12) is loaded to pivot connections that are in the front portion of theexercise machine 10. -
FIG. 5 illustrates a view of an example of a secondframe pivot connection 13 in accordance with the present disclosure. In this example, the secondframe pivot connection 13 includes apivot rod 82 that connects the stationaryhorizontal base 12 to theframe 14. Theframe 14 includes ahousing 16 that supports thesecond flywheel 20. Thesecond post 68 is depicted contacting thehousing 16. Theframe 14 can pivot about thepivot rod 82 to change the angle between theframe 14 and the stationaryhorizontal base 12 as illustrated inFIG. 6 . Preferably, as the secondframe pivot connection 13 changes the angle between theframe 14 and the stationaryhorizontal base 12, the firstframe pivot connection 11 also changes its angle by the same amount. -
FIG. 7 illustrates a cross sectional view of an example of aframe 14 in accordance with the present disclosure. In this example, thehousing 16 is partially cut away to illustrate the frame structure within thehousing 16. Theangling mechanism 84 is used to change the angle of theframe 14 relative to the stationaryhorizontal base 12. Thesecond post 68 of theframe 14 includes apiston connection 86 where theangling mechanism 84 can push thesecond post 68 to change the angle. - The
angling mechanism 84 can be arranged such that apiston 88 of theangling mechanism 84 can move along the length of the angling mechanism. As thepiston 88 extends, thepiston 88 pushes against thepiston connection 86 on a single side of thesecond post 68 such that the side of thesecond post 68 moves up with thepiston 88. However, the secondframe pivot connection 13 acts as a fulcrum about which thesecond post 68 pivots. As a result, the incline angle of the functional portion of theexercise machine 10 increases and the angle between theframe 14 and the stationaryhorizontal base 12 also changes. As thepiston 88 retracts, the single side of thesecond post 68 moves down with thepiston 88 and causes the incline angle of the functional portion of theexercise machine 10 to decrease. - The
piston connection 86 may be integrally formed in thesecond post 68. In alternative examples, thepiston connection 86 is formed by an attachment connected to thesecond post 68. Further, theangling mechanism 84 may be positioned to move thesecond post 68, thefirst post 66, another portion of theframe 14, or combinations thereof. Theangling mechanism 84 may be arranged to move theframe 14 any appropriate number of degrees. The range that theangling mechanism 84 is capable of inclining theframe 14 with respect to the stationary horizontal base may be a limited range. For example, theangling mechanism 84 may be arranged to move the frame up to 60 degrees, up to 45 degrees, up to 35 degrees, up to 25 degrees, up to 10 degrees, up to another number of degrees, up to degrees there between, or combinations thereof. - Any appropriate type of
angling mechanism 84 may be used in accordance with the principles described in the present disclosure. For example, theangling mechanism 84 may include a hydraulically driven piston, a pneumatically driven piston, a rotatable piston that moves vertically based on a thread form, another type of piston, a linear actuator, a solenoid, or combinations thereof. In other examples, theangling mechanism 84 does not use a piston. Such examples my use motors, cables, thread forms, non-linear actuators, magnetic forces, electric forces, hydraulic pressures, pneumatic pressures, other types of pressures, gears, screw motors, other types of angling mechanisms, or combinations thereof. In addition to being capable of producing a force sufficient to change the angle between the stationaryhorizontal base 12 and theframe 14, theangling mechanism 84 may also include an ability to maintain the angle. For example, theangling mechanism 84 may be able to hold the weight of theframe 14 in the angled position while the user works out on theexercise machine 10. Further, while the example ofFIG. 7 has been described with reference to theangling mechanism 84 being located outside of thehousing 16, theangling mechanism 84 may be positioned inside thehousing 16 in alternative examples. - The user may cause the angle between the
frame 14 and the stationaryhorizontal base 12 to change with any appropriate mechanism. For example, thecontrol module 62 may include a button, a lever, a touch screen, or another type of mechanism that can be used to receive input from the user about the user's desired angle. In such examples, the user may select any appropriate angle within a range of angles that theexercise machine 10 is capable of producing. In other examples, such an input mechanism is incorporated intofirst arm support 38, thesecond arm support 42, another portion of theframe 14, or combinations thereof. In some examples, a program of a remote device, such as a phone, a laptop, an electronic tablet, a desktop, another type of mobile device, or combinations thereof may be used to control the angle between theframe 14 and the stationaryhorizontal base 12 wirelessly. In yet other examples, theexercise machine 10 may respond to audible or voice recognized commands to change the angle. - As the angle between the stationary
horizontal base 12 and theframe 14 change, the exercise machine's center of gravity may also change. The stationaryhorizontal base 12 may have a shape that is capable of supporting the weight of theframe 14 over multiple positions with different centers of gravity. For example, the stationaryhorizontal base 12 may have a length that is sufficient to support differing centers of gravity. Further, the stationaryhorizontal base 12 may be made of any appropriate type of material that is capable of supporting the frame and associated components over multiple positions. - While the examples above have been described with reference to exercise machines that specifically have multiple flywheels, the exercise machine may include any number of flywheels. For example, the principles described in the present disclosure can be applied to exercise machines that incorporate just a single flywheel or no flywheel at all. Further, while the examples above have been described with specific reference to an elliptical exercise machine that provides a user the ability to both work out by sliding the foot pedals and rotating the crank assembly, the principles described in the present disclosure can be applied to exercise machines that provide just one of these types of aforementioned workouts. Further, while the examples above have been described with reference to elliptical machines, any appropriate type of exercise machine may incorporate the principles described in the present disclosure.
- In general, the invention disclosed herein may provide a user the advantage of targeting different muscle groups during a workout or adjusting the difficulty of a workout. This may be accomplished by changing the angle between the frame and the stationary horizontal base of the exercise machine. When the frame's angle relative to the stationary horizontal base is changed such that the incline of the functional portion of the exercise machine increases, the difficulty of the workout increases for the user. Likewise, when the frame's angle relative to the stationary horizontal base changes such that the incline decreases, the difficultly of the workout is reduced.
- The principles described in the present disclosure can be applied to any appropriate type of exercise machine. For example, these principles may be applied to an elliptical machine, a stationary bike, a striding machine, a stepper machine, another type of exercise machine, or combinations thereof. Further, these principles are well suited for elliptical machines with a single flywheel, no flywheel, or multiple flywheels.
- The entire functional portion of the exercise machine may rotate with the frame as the frame changes position relative to the stationary horizontal base. For example, the arm supports, foot pedals, mechanical linkages, tracks, flywheels, resistance mechanisms, crank assemblies, and other components of the exercise machine may move with the frame as the frame changes positions.
- Further, the user may control the angle between the frame and the stationary horizontal base with an incline controller that is located in a convenient location. For example, the convenient location may be within an arm's reach of the user while the user is standing in an upright position on the foot pedals, such as in an arm support or the control module. In other examples, the incline controller is incorporated in a position that is convenient for the user while the user is standing adjacent to the exercise machine.
- In some examples, the angling mechanism has a capability of producing forces that are sufficient to change the angle between the frame and the stationary horizontal base as well as maintain that angle. In other examples, the angling mechanism is capable of changing the angle while another mechanism is used to maintain that angle.
