Description

United States Patent 1191 Perkins DEVICE SIMULTANEOUSLY DISPLAYING PORTIONS OF BOTH SIDES OF AN ENDLESS BELT [76] Inventor: Gary Perkins, 474 N. Milwaukee Ave., Chicago, 111. 60610 [22] Filed: Jan. 10, 1973 [21] Appl. No.: 322,369

[1 11 3,798,809 [4 1 Mar. 26, 1974 255,968 8/1926 Great Britain 40/96 Primary ExaminerF. Barry Shay Attorney, Agent, or Firm-George H. Gerstman [57] ABSTRACT A wheeled toy vehicle or the like is provided, and includes an endless belt having indicia on both sides and roller means and surface guide means about which the belt is trained which are arranged so that the belt moves along a first surface with a first side exposed and along a second overlying surface with the second side exposed. In the illustrative embodiment, the overlying surface is shaped to be suggestive of a bridge, the first side of the belt is printed with water-suggestive indicia and the second side with representations of automobiles so that as the vehicle is pulled, the belt is driven and the impression of automobiles moving over a bridge under which water is flowing is created.

5 Claims, 7 Drawing Figures DEVICE SIMULTANEOUSLY DISPLAYING PORTIONS OF BOTH SIDES OF AN ENDLESS BELT BACKGROUND OF THE INVENTION This invention relates to toys, display devices and the like which employ endless belts to create a desired visual impression.

The use of flat, endless belts printed only on one side to create visual impressions is well-known, as disclosed in US. Pat. No. 843,642. In order to carry more information, the belts have been printed on both sides and twisted so that during movement both sides are exposed, as in the Mobius sheet; see, for example, British Patent Nos. 6,625 of 1894 and 255,968.

I have found that an attractive and useful display is created by providing a wheeled vehicle which, when moved, operates to move an endless belt having a crossover portion so as to display the indicia on both sides of the endless belt, with one side of the endless belt facing the viewer overlying the other side also facing the viewer.

SUMMARY OF THE INVENTION There is provided by virtue of this invention a device, which can be used as a childs pull-toy, that employs a flat, endless belt which is trained about various rollers and guide means so that one portion of the belt moves over another portion in overlying relationship and at right angles thereto. Indicia are provided on both sides of the belt so that as the belt moves, different sides of the belt are exposed when the one portion of the belt passes over the other. It will be appreciated that in addition to use as a pull-toy, such a device can be used as an advertising display or the like.

A more detailed explanation of the invention is provided in the following description and claims, and is illustrated in the accompanying drawings.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a pull-toy made in accordance with the invention;

FIG. 2 is a plan view of the toy shown in FIG. 1;

FIG. 3 is a side elevational view of the pull-toy shown in FIG. 1;

FIG. 4 is an end elevational view of the pull-toy shown in FIG. 1;

FIG. 5 is a bottom plan view of the toy of FIG. 1 with the belt removed;

FIG. 6 is a fragmentary perspective view showing the endless belt and a pair of rollers for changing the direction of movement thereof; and

FIG. 7 is a diagrammatic perspective view showing the endless belt and the direction of its movement.

DETAILED DESCRIPTION OF THE ILLUSTRATED EMBODIMENT Referring to the drawings, the vehicle 10 includes a pull-string 11 attached to an elongated carriage 12 having front and

back ends

14 and 16, respectively, and a planar guide surface 17 therebetween.

Referring to FIG. 5, each end includes a pair of spaced

ears

14a, 14b and 16a, 16b. Front and back rollers l8 and are mounted to the carriage in spaced parallel relation between the ears by shafts 18a and 20a, respectively, which pass through the respective ears and connect to the

wheels

22, 24, 26 and 28.

A curved bridge-like member 30 is centrally mounted to the sides of the carriage to define a second guide surface 30a which extends over and is in overlying relationship with the planar guide surface 17. Each of a pair of spaced

idler rollers

32 and 34 is mounted to the outboard sides of the carriage adjacent the lower ends of the member 30 and between pairs of spaced

ears

36a, 36b, 38a and 38b to which the

roller support shafts

32a and 34a are journaled. The axes of rotation of the side rollers lie in substantially the same plane as the axes of rotation of the end rollers but in a direction transverse thereto.

A pair of parallel, closely spaced, direction-changing

rollers

40 and 42 are journalled for rotation by shafts 40a and 42a to the underside of the carriage 12 and spaced below the planar guide surface 17. The axes of rotation of these rollers lie in substantially the same plane as the axes of the end and side rollers and at about a 45 angle to each of said axes.

An endless belt 44 having

sides

44a and 44b on which water-suggestive indicia and representations of auto mobiles are printed respectively, is trained about the rollers and guides so that side 44a is positioned upwardly as it moves on surface 17 below the overhead guide and the other side 44b is positioned upwardly as it moves over the overhead support 30 at right angles to the lower belt portion.

Beginning at the back end roller 20, the belt is trained thereabout, over the planar surface 17, about the front end roller 18 and to the direction-changing roller 42. The belt is threaded from the underside of roller 42 over the top thereof, to the outboard side roller 34, over the overhead support 30a, over the outer outboard side roller 32 and back to the other directionchanging roller 40. The belt enters this roller from the bottom, passes between the rollers and exits from the bottom side and then extends to the back end roller 20.

In operation, as the vehicle is pulled forwardly, the wheels drive the front and back rollers, which grippingly engage the belt 44, thereby moving it so as to create the impression of automobiles driving over a bridge under which water is flowing.

It is understood that numerous designs can be provided on the sides of the. belt. Furthermore, rather than moving the vehicle it can be stationary with the wheels held against a moving surface. In other arrangements, the belt could be driven directly in a sprocket-andchain-like manner or the roller shafts could be driven directly by a motor. One skilled in the art will appreciate that these and other modifications can be made to the embodiment disclosed herein without departing from the spirit and scope of this invention.
