No. 133,589 11 Claims. (Cl. 46-244) This invention relates to electric toys, and more particularly to an electric toy adapted automatically to travel up and down an inclined track.

Among the several objects of this invention may be noted the provision of a toy adapted to be electrically powered up an inclined track, and upon reaching the Lipper end of the track automatically to turn off the electric power, thereby permitting the toy to descend the track to the lower end thereof, whereupon the electric power is again turned on and the toy again climbs up the track; the provision of such a toy having an object, such as a toy race car, which is always headed in the direction of movement of the toy regardless of whether the toy is ascending or descending, i.e., the object is automatically turned substantially 180 at the end of each run; the provision of a toy of the class described including a novel expansible frame which is relatively compact before the toy is set up, but which can be substantially expanded for providing a long track; and the provision of such a toy which is of relatively simple and economical construction and reliable in operation. Other objects and features will be in part apparent and in part pointed out hereinafter'.

The invention accordingly comprises the constructions hereinafter described, the scope of the invention being indicated in the following claims.

In the accompanying drawings, in which one of various possible embodiments of the invention is illustrated,

FIG. 1 is a side view of the toy of this invention show ing the frame thereof expanded;

FIG. 2 is a plan view of FIG. l;

FIG. 3 is a section taken on line 3-3 of FIG. 1;

FIG. 4 is a plan view of the frame of the toy in its collapsed position;

FIG. 5 is an enlarged View in elevation of the power apparatus for the toy;

FIG. 6 is a section taken on line 6 6 of FIG. 5 and FIG. 7 is a perspective view of a plunger of the toy.

Corresponding reference characters indicate corresponding parts throughout the several views of the drawings.

Referring to the drawings, a toy device of this invention is shown to comprise a frame generally indicated at 1, a track or wire means 3, and a movable toy generally designated 5.

Frame 1 includes a central base 7 adapted to rest upon the fioor or ground. A groove 9 is provided in each side of the base 7. Slidably mounted on base 7 are two extension arms 11. Each arm 11 has two parallel side pieces 13, the inner ends of each of which are joined by a bracket 15. Tongues 17 on side pieces 13 are received within grooves 9 of base 7. Screws 19 extend through the brackets 15 and side pieces 13 for clamping the arms 11 rigidly to the base 7. A relatively long upstanding leg 21 is attached to the outer end of one arm 11 and a shorter upstanding leg 23 is attached to the outer end of the other arm 11. Both of the

legs

21 and 23 are supported by triangular brace members 25.

Track 3 is shown in the form of a wire 27. However, it will be understood that track 3 could be of other forms, such as string for example. Wire 27 extends from a point adjacent base 7 along the left arm 11 as viewed in FIG. 1, through a hole 29 at the bottom of leg 21, up the outside of leg 2.1, through a hole 31 in the upper end of leg 21, down to a hole 33 in the upper end of leg 23, down the outside of leg 23, through a hole 35 in the bottom of leg 23, and along the right arm 11 back to a point adjacent ICC base 7. A turnbuckle 37 is attached to the ends of wire 27 for tightening the wire on the frame 1.

The frame 1 and track 3 are shown in collapsed form in FIG. 4. Thus the frame of the toy device may conveniently be reduced in size for storage or shipping. In its expanded position the frame may have a length of 40, for example, and the

legs

21 and 23 may have heights of 12 and 7", respectively, with the

holes

31 and 33 being spaced 1 from the top of the respective legs.

The movable toy 5 is shown in FIG. 1 in solid lines as it appears just as it begins its descent down wire 27, and in dotted lines as it appears just as it begins its ascent up Wire 27. In FIGS. 5-7 the detailed construction of the movable toy is seen more clearly. A body or housing is indicated at 39. Mounted within body 39 is a conventional flashlight battery B and a small motor M. Body 39 comprises two

parts

41 and 43 hinged together at 45 and releasably latched at 46 so that the body may be opened for insertion or removal of battery B and motor M.

Motor M is provided with a power shaft 47 which extends out through body 39. Mounted on shaft 47 is a small roller i9 adapted to be in frictional contact with a larger roller 51. Roller 51 is fixed on one end of a shaft 53 extending through body B. On the other end of shaft 53 is a V-grooved driven wheel 55 adapted to ride on wire 27. Energization of motor M will cause wheel 55 to rotate in a counterclockwise direction as viewed in FIG. 5.

A pair of wheels 57 is attached to the upper portion of body 39 for maintaining the movable toy balanced on the wire 27. A channel C is provided in the upper portion of body 39. An elongate bar or plunger 59 having enlarged heads 61 is slidably mounted within channel C and extends outwardly from each end of body 39. Bar 59 is adapted to be pushed to a first position (solid line position in FIG. 5) when the head 61 on the lower end of the bar engages leg 23, and to be pushed to a second position (dotted line position in FIG. 5) when the head 61 on the left end of the bar engages leg 21.

An electrically conductive plate 63 is embedded in bar 59. Body 39 is provided with two contacts 65 Iand 67 facing channel C. Contact 65 is connected by a wire 69 to one pole MP1 of motor M. Contact 67 is connected by la wire 71 to a pole BPI of battery B. A wire 73 connects the other pole MP2 of the motor M to the other pole BP2 of battery B. When the bar 59 is in its first position, i.e., when pushed to the left as viewed in FIG. 5, plate 63 connects

contacts

65 and 67, thereby energizing the moto-r M for rotating wheel 55. When bar 59 is in its second position, i.e., when pushed to the right as viewed in FIG. S, contacts 65 Iand 67 are disconnected and motor M is deenergized.

Bar 59 is also provided with a rack 75. Rotatably mounted on a post 77 extending up from body 39 is gear 79 in mesh with rack 75. A sleeve 81 extends upwardly from gear 79 and around post 77. Sleeve 81 is attached to the undercarriage of an object O, such as a race car or airplane. As bar 59 moves from the position shown in solid lines in FIG. 5 to the position shown in dotted lines or vice versa, rack causes the object O to be rotated substantially Referring to FIG. 1, and assuming the frame 1 and track 3 have seen setup, the movable toy placed on the track, the motor M deenergized, and the object O is a racing car, operation is as follows:

The movable toy 5 rolls down the inclined track toward leg 23 due to gravity. The head 61 on the right end of bar 59 strikes the upper portion of leg 23 upon arrival of the toy `at the right end of the track and is thereby pushed from a position wherein it extends out from the right side of body 39 to a position wherein it extends` out from the left side of body 39.

Contacts

65 and 67 are thereby connected and motor M is energized to drive wheel 55. During movement of bar 59 from one position to the other as described above, rack 75 causes the gear 79, sleeve 81 `and racing car to be rotated 180, thereby turning the car around to head up the track. Rotating wheel 55 then causes the toy 5 to climb the track toward the upper end thereof. Upon arrival at the upper end of the track, bar 59"is pushed to the right to its original position, thereby deenergizing the motor M and rotating the car 180 so that it faces down the track, whereupon the above process is repeated.

While it is contemplated that the body B and rod 59 be constructed of plastic, it will be understood that other materials may be used without departing from the spirit of this invention. It will also be understood that other types of driving connection may be used between motor M and wheel 55, such as a belt or gear arrangement.

In view of the above, it will be seen that the several objects of the invention are achieved and other -advantageous results attained.

As various changes could be made in the above constructions without departing from the scope of the invention, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.
