MONORAIL TOY Filed Sept. 28,1958,
Patented June 25, 1940 UNITED STATES PATENT :OFFlCE 1 Claim.
My invention relates to improvements in toys,
and more particularly to the type in which a small vehicle travels on a monorail. Preferably the vehicle represents flying things as airplanes, 5 birds, butterflies, bat and bird men, Zeppelins,
In one form of the invention the track is made of string, cord, or flexible wire held in two substantially parallel strands, to form a closed loop, by means of reinforcing rigid curved end members, the latter being provided with suitable supports such as handles, by means of which the flexible strands may be held under tension to keep them from sagging appreciably.
In another form the track is made of wire or other light weight material of small cross section but stiff enough to maintain itself with out being held under tension.
In the drawing:
Fig. l is a perspective view of a monorail in the form of a closed loop;
Fig. 2 is a section on the line 2-2 of Fig. 1;
Fig. 3 is a section on the line 3-3 of Fig. 1;
Fig. 4 is a bottom view, on an enlarged scale, 5 of one of the rigid curved ends;
Fig. 5 is a modification of the form shown in Fig. 1;
Fig. 6 is an elevation of a pulley and bracket, comprising part of a toy vehicle; and
Fig. 7 is a perspective view of a toy Bat Man.
In Fig. 1, the monorail I is in the form of a loop or string or cord or other flexible material, and is provided with substantially rigid, curved reinforcements I l at each end of the loop which maintain said ends in semi-circular form. One 'form of reinforcement is shown in Figs. 2,3 and 4 as a sheet of metal bent over on itself in an inverted U-shaped form so as to embrace the string ID somewhat like aclamp. In other words, 40 a channel is formed through which the string may be threaded. The metal reinforcement has a generally semi-circular form to provide smoothly curved ends for the loop or track. As shown in Fig. 3, the parallel arms I 2 of the U-shaped member may be pressed together to clamp the string in place to hold it against slipping, or to clamp one end of the string in case the two parallel strands are made of two single lengths of string.
The reinforcing members l are provided with supporting devices l3 which may be used as handles, which handles may in one form consist of a piece of sheet material, curved as shown in Fig. 4, to fit into the bottom of the slot and either soldered in place, riveted or held frictionally by pressing the side walls l2 of the slot together. The curvature of the handle stiffens it, particularly where it is made of sheet metal. The handles may be held in the hands, or one of them at least may be mounted on a fixed support. For
this purpose one handle may be offset as indicated at M at the left-hand of the loop, so that as the vehicle travels around the semi-circular end of the track it will clear the support. Said handles or supporting brackets may be provided also with openings I5 to enable them to be nailed or screwed to a post, a tree, or other suitable support. It will be understood, of course, that both handles may be provided with the offset l4, if desired or, as shown at the right hand end, an eyelet l6 may be provided, so that if the handle is hooked or tied to a fixed support it will have a tight swivel action, as hereinafter explained.
The vehicle may be constructed in various different forms, one appropriate form being shown in part in Fig. 6, in which a small pulley I1 is mounted in the upper end of a depending U- shaped support I8. The toy, such as representation of an airplane, bird, etc., may be cut out of paper or metal, and secured to the support I8 in any suitable manner, so as to simulate a flying insect I9, shown for example in Fig. 1, or a vehicle in the form of an airplane (not shown) or a Bat Man as in Fig. '7. The arrangement is such that the center of gravity is below the string or wire Ill, and the depending arms of the U- shaped member clear the metal reinforcements H as the vehicle rounds the turns. Various other forms of frames may be used to carry the device which represents the flying object.
Where the handles are held each in one hand, they are held apart so as to maintain the flexible track Ill under tension, and by lowering one end or the other of the track and tilting the same appropriately the vehicle may be caused to run around the loop in one direction or the other.
Instead of holding both handles in the hand, one handle may be tied or hooked to the end of a chair or other convenient object, while the other end is raised or lowered to produce the necessary down grade to propel the vehicle around the course. By using the eyelet l6 iii tying or hooking the device to the stationary object, the necessary swiveling or tilting of the track may be effected by manipulating the handle at the distant end. In such case the U-shaped member l8 clears the eyelet, which is below the level of the track or monorail.
It is also evident that where one end of the monorail loop is secured to a fixed object, the
loop may be made almost indefinitely long, i. e., the track may extend across the room or the length of the lawn, if the device is used outdoors. In Fig. 5 the ends of the loop may be assumed to be of the same construction as those previously described, but the flexible cord or cords lfi cross each other, the handles being so held that one span of the string is above the other. Thus the vehicles may travel on a figure 8 track.
Although one-wheel vehicles are preferable, it is apparent that an additional wheel or wheels may be used, if desired. However, the light weight of the vehicle is one of the features of
