DISPLAY DEVICE Filed Sept. 19, 1958 INVENTOR.

HAELEV E. FREEZE United. S tat5 Pfltm This invention relates to display devices and, more specifically, to a picture display device which is operable to produce a plurality of indicia by its selective operation.

An object of thisinvention resides in the provision-of a picture display device wherein segments of the pictures to be exhibited are printed on movable strips, and the strips are capable of alinement in various positions toprovide a plurality of different pictures utilizing the aforesaid segments in different arrangements. I.

While devices of this general type are often employed as childrens toys, they'are also capable of many other important functions, such as, for example, educational testing machines, advertising display apparatus, and other visual communication machines. r

Another object and advantage of one form of this invention is to provide a device of this general character wherein the movable strips are easily and quickly disconnectable from, and attachable to, their carrying means. This feature allows the provision of a number of different picture strips thereby increasing'the possible forms of utilization of this device as well as the interest span of children playing with the device when it is in use as a toy.

Another object is, in a device of this class, to afford novel and improved control means which are easily actuated, but, at the same time, allow positive positioning of the various pictures.

, Among the further objects of this invention is the provision of a display device of the class described supra,

the display device being non-complex in construction and assembly, inexpensive to manufacture,.and durable in use.

Numerous other and further objects and advantages will become more readily apparent from a consideration of the following specification when read in conjunction with the annexed drawing, in which:

Figure 1 is a front elevational view of a display device constructed and assembled in accordance with the teachings of this invention; 7 r 1 Figure 2 is a vertical detail cross-sectional view of the toy seen in Figure l, the section being taken substantially along the plane of the section line 22 of Figure 1, looking in the direction of the arrows;

I Figure 3 is a detail cross-sectional view of the device, the section being taken substantially along the horizontal 2 housing 12 being designated at 16. The base 14 has a flange 18 projecting upwardly therearound, the flange being adjacent to but spaced from the outer marginal edgesthereof, and the open end of the housing 12 is press fit around the aforesaid flange. The front wall of the main body 12, identified by reference numeral 20, has an arcuate protuberance 22 which is cut out at 24 to form a viewing and access door opening described more fully below, and the base 14 and flange 18 thereof are likewise extended to accommodate the protuberance 22.

A bowed viewing and access door 26 extends across the cut-out portion of the front wall 20 and is hingedly secured thereto at 28, 30. The door 26 is transparent and may be formed of any suitable material, and an intergrally formed handle 32 is formed on the outer side thereof.

The indicia carrying assembly and actuating means are identified by general reference numeral 34 and includes a plurality of picture carrying, nested skirts, having a common rotational axis. In this embodiment of the invention, three skirts have been illustrated, but it should be clearly understood that it is within the scope of this invention to provide any number thereof.

A bottom skirt 36 is seen to include a parabolic main body 38 having an annular rim 40 depending from the outer marginal edge thereof. Also, a substantially cylindrical control shaft 44 having a threaded upper end 45 extends upwardly from the apex of the main body 38.

. A centrally disposed skirt 46 is similar to the bottom skirt 36 and includes a parabolic main-body 48 and a depending rim 50. The control shaft 52 thereof extends upwardly from the apex of the main body 48 and has an axially extending bore 54 through which the control member 44 of thebottom skirt 36 is slidably and rotatably passed. As seen in Figure 2, the upper end of the control 52 is also threaded at 53 for a purpose described below.

The upper skirt 56 has a parabolic main body 58 and depending rim 60 as Well as a cylindrical control shaft 62. The control shaft-62 has a threaded outer end 63 and an axial bore 64 through which the control shaft 52 is slidably and rotatably passed.

Referring to Figures 1 and 2 of the drawing, it willbe seen that the closed end 16 of the housing 12 has a centrally disposed substantially cylindrical boss 66 having a series of circumferentially spaced, pointed depressions 68 formed therein. An annular lower control knob 71 is threadeadly connected to the control shaft 62 and has pointed circumferentially spaced projections 72 which plane of the section line 33 of Figure 1, looking in the Y direction of the arrows;

Figure 4 is an exploded perspective view of the rotating mechanism, and picture carriage means, forming a part of this invention; and

Figure 5 is an exploded view of a modified form of one of the nested skirts and its picture strip, illustrating the means whereby the strip is attached to the skirt.

Proceeding now to a more specific description of the invention, with special reference to Figures 1 through 3 of the drawing, it will be seen that reference numeral 10 is applied to the display device in general. The device 10 has a substantially rectangular main body housing 12 having a pair of opposed open and closed ends and a substantially flat, rectangular base 14, the closed end of the are engageable' in the aforementioned depressions 68, and the opposed upper side thereof has a plurality of spaced radial depressions 79 formed therein; A central control knob 76 is threadedly' connected to the control shaft 52 and is identical in construction to the knob 70 with the single exception that the threaded opening is necessarily of a lesser diameter than the threaded opening of the last named knob. The uppermost knob 78 has a fiat outer end and an opposed inner end which is provided with spaced radial projections 80 for engagement within the depressions in the upper end of the knob 76. The knob 78 is threadedly secured to the upper end of the shaft 44.

Each of the rims 40, 50, and 60 is provided with a series of indicia 82, and it will be noted that the indicia carried by each of the rims are capable of selective alinement relative to each other in order to form completed figures as shown in Figure 1. In this form of the invention, the indicia 82 may be either printed or otherwise aflixed directly on the rims 40, S0, or 60.

In operation, the device is assembled in the manner obvious from the description of its parts and is utilized as follows: When it is desired to change the picture appearing in front of the viewing door 26, this is done by manipulation of the control knobs 70, 76, or 78. It is. obvious that the indica 82 on the rim 40 comprise the leg;

portions of animated characters, while those on the center rim 50 represent the trunks of said characters, and the indicia on the rim 60 portray the heads of such characters. The rotation of the control knobs 70,76, and 78 causes rotation of the corresponding rims. Thus, by collective rotation of all of the knobs, the entire assembled pictures may be rotated, or if desired, by rotation of a selected one of the aforementioned knobs, the leg per-' corresponding depression and thus move upwardly. For; example,if the knob 78 is rotated the projections 80 W11].

rise against-the curved sides leading to the depressions in the knob 76, thus causing the shaft 44 to rise in the bore 54 and to lift and rotate the skirt 36. The knobs are seen to rotate with the cam actionas described above, and the seating of the radial projections in the corresponding depressions of the knobs and the boss causes a positive operation in the rotational movement of the various skirts and in the alignment of the various indicia.

In a modified form of the skirt, illustrated in Figure 5 of the drawing, the skirt 36a has a parabolic main body 38a and depending rim 40a. It is seen that the rim 40a is slotted at 84, and an annular picture strip 86 is provided for surrounding the rim 40a. The strip 86 is split at 88 and has inwardly turned confronting flanges 90, 92 at the split, the flanges being provided for insertion in the slot 84 of the rim 40a. The operation of the modified form is substantially the same as that previously described. However, in the latter case it is possible to substitute various sets of strips 86 on the various lower, central, and upper rims (which are all provided with slots as at 84). The substitution may be accomplished without complete disassembly of the device by merely opening the viewing and access door '26 and disengaging one of the flanges 90 or 2 from the slot 84 and then rotating a selected rim while at the same time withdrawing the strip 86. When a complete rotation has been effected, the other one of the flanges is removed from the slot. The

-foregoing process is merely reversed when another set of picture strips are to be connected to the rims.

It will readily be seen that many different means may be employed for securing the picture strips to the rims in addition to the novel means herein before described. For example, studs, snap fasteners, or other equivalent devices could be employed for this purpose.

Having described and illustrated two embodiments of this invention in detail, it will be understood that the same are offered merely by way of example and that this in vention is to be limited only by the scope of the appended claims.
