HG. 9 0501/? FRANC/5 L//VDSTQOM A T TOR/v5 isA United States Patent O 3,263,364 ELECTRICALLY OPERATED TOY AUTO AND GUIDE RAIL Oscar Francis Lindstrom, Great Falls, Mont., assigner of one-half to David I. McKay, Great Falls, Mont. Filed Uct. 3, 1963, Ser. No. 313,690 3 Claims. (Cl. i6-244) My invention relates generally to toys and more particularly to minature vehicles.
Still more specically, my invention relates to and provides a novel electric motor-propelled miniature vehicle and a novel tape for guiding and imparting power thereto.
An important object of my invention is the provision of a novel tape for guiding and imparting power to miniature vehicles having an electric motor operatively coupled to a pair of rear wheels, a pair of dirigible front wheels, and a pair of laterally spaced brush elements associated with the motor which are interposed between the path `of travel of said wheels and which are yieldingly `biased towards each other transversely of said path of travel, said tape being in the nature of a vertically disposed flexible resilient ribbon adapted to be received between said brush elem-ents and formed to define a pair of longitudinally extended parallel electrical conductor elements having insulator means therebetween and one each exposing a brush-engaging surface on opposite sides thereof.
A further object of my invention is the provision of a tape of the type immediately above described which is sufficiently flexible to permit lateral flexation and adjustment on a horizontal supporting surface.
A further object of my invention is the provision of a tape of the class above described wherein said conductor elements and said insulator means are in the nature of laterally disposed laminae.
A still further object of my invention is the provision of novel means on said miniature vehicle associated with said front wheels for transferring electrical energy from said guide tape to said electric motor.
The above and still further objects of my invention will become apparent from the following detailed specification, appended claims, and attached drawings.
Referring to the drawings wherein like characters indicate like parts throughout the several views:
FIG. 1 is a fragmentary view in perspective of my novel guide-track showing my novel vehicle mounted thereon;
FIG. 2 is an enlarged view in longitudinal section taken on the line 2-2 of FIG. l;
FIG. 3 is a plan View as seen from the line 3*.3 of FIG. 2, portions thereof removed;
FIG. 4 is a transverse sectional view taken on the line 4-4 of FIG. 2, on an enlarged scale;
FIG. 5 is a view in transverse section taken on the line 5-5 of FIG. 2, on an enlarged scale;
' FIG. 6 is an enlarged fragmentary view in horizontal section as seen from the line 6-6 of FIG. 2;
FIG. 7 is a transverse sectional View as seen from the line 7 7 of FIG. l, on an enlarged scale;
FIG. 8 is a view in transverse section as seen from the line 8-8 of FIG. l, on an enlarged scale; and
FIG. 9 is an enlarged fragmentary sectional View as seen from the line 9-9 of FIG. 6.
Referring with greater particularity to the drawings, my novel tape, identified in its entirety by the numeral 10, is comprised of laterally spaced upstanding tape sections 11, 12, and 13 in the nature of bonded laminae. Tape sections 11 and 12 are flexible, preferably of resilient metallic strips capable of conducting electrical energy, whereas lamina 13 is a suitable insulating and bonding member.
For a purpose which will hereinafter become apparent, the conductor elements 11, 12 define, respectively, brushengaging opopsite side surfaces 11a, 12a.
Electrical energy, from a source not shown, is supplied to the conductor elements 11, 12 of the tape 1t) by means of suitable lead wires collectively identified by 14 and a cooperating coupler element 1S, as seen particularly in FIGS. l and 8. For the purpose of maintaining the guide tape 10 in a vertically disposed operative position, I provide Iat longitudinally spaced points therealong suitable supporting members preferably in the nature of rubber blocks 15 having central channels 17 cut therethrough for the snug reception of said tape 1li, as illustrated particularly in FIG. 7. However, I wish to emphasize that the tape 10, 'by virtue of its inherent characteristic, is self-supporting when formed either into a circular or serpentine shape.
My novel miniature vehicle adapted to be guided by and derive power from tape 1li comprises a frame or chassis 18 having an electric motor 19 suitably mounted thereon. Suitably journalled in the frame or chassis 18 is a horizontally disposed and transversely extended axle 2li having rear wheels 2l fast on opposite ends thereof. Mounted upon the axle 20 intermediate the wheels 21, for common rotation therewith, is a driver gear 22 which has meshing engagement with an idler gear 23, which in turn has meshing engagement with a drive: gear 24 fast on the output shaft 25 of motor 19.
The dirigible front wheels 26 are journalled on opposite ends of a front axle 27. Axle 27 intermediate the wheels 26 is mounted for rotation on a vertical axis 28.
As shown particularly in FIG. 4, this is accomplished through the medium of an inverted yoke 29, depending opposite ends 30 of which encompass said axle 27 and the intermediate portion of which is provided with an upstanding pivot pin 28 which passes through the lower fork 32 of a bifurcated mounting bracket 33 carried by the frame 13 and is received within a downwardly opening recess or socket 34 in the upper fork 35 of said bracket 33. A collar 31 fast on the pivot pin 23 intermediate the forks 32, 3S maintains the pin 28 in its operative position during removal of the vehicle from the tape 1li. This arrangement obviously permits combination steering and rocking movements to be imparted to the front wheels 26 with a minimum of friction.
Pivotally secured to the intermediate portion of front axle 27 for raising and lowering movements, and projecting longitudinally, preferably forwardly therefrom, is a mounting arm 36. Journalled for rotation about a Vertical axis to the projected forward end of the mounting arm 36 is a depending pivot pin 37. Pivotally secured on the vlower end of pivot pin 37 is a carriage 38, which, as shown particularly in FIG. 6, comprises a pair of laterally spaced longitudinally extended arm elements 39 secured together by means of wall-like cross members 39a. Projecting through opposite end portions of the arm elements 39 are shafts 4t), 41 having guide-wheels 42, 43, respectively, mounted thereon for common rotation therewith. As shown, guide-wheels 42, 43 are formed at their peripheries to define grooves 42a, 43a, respectively, for reception of the upper edge portion 44 of the tape 1). Wheels 42 and 43 are in non-conducting relationship to the metallic strips 11 and 12. Projecting through the intermediate portion of the arm elements 39 and the lower end of pivot pin 37, and journalling same for pivotal movements about a horizontal axis, is a pivot pin 45.
As shown particularly in FIGS. 2, 5, 6, and 9, longitudinally spaced pairs of laterally spaced legs 46, having their upper end portions secured for limited compound sliding and pivotal means, one pair on each wall-like cross member 39a, as indicated particularly in FIG. 9. This is accomplished by means of pivot pins 47 fast on the upper end of each of the arms 46 and slidably, pivotally received in transversely extended slots 48 in said cross members 39a, one each on opposite sides of the transverse center thereof. Extending between the free ends 46a of the arms 46 and secured thereto, as indicated at 49, one each on an opposite side of tape it), is an elongated brush element 50, preferably and as shown having a cylindrical cross section. Yieldingly biasing each pair of arms 46 and the 'brush elements 50 carried thereby toward each other and towards engagement with the brush-engaging surfaces 11a, 12a, of the tape 10 are suitable springs 51, as shown, being of the coil-compres sion type.
Leading from the upper end portions of the legs 46 and having operative connections with the motor 19 are lead wires identified collectively by 52.
When it is desired to operate my novel vehicle, above described, the guide-tape l0 is first placed upon a horizontal supporting surface to define a desired path of travel; thereafter the vehicle is placed thereover with the wheels 21, 26 in straddling relationship to the tape 10. Finally, the carriage 38 is elevated by raising the mounting arm 36 and the guide-wheels 42, 43 are placed in overlying relationship to the upper edge 44 of the track 10 in tandem relationship with the grooves 42a, 43a, receiving said upper edge 44. As this operative relationship is assumed under the action of gravity, the brush elements 50 will be spread apart against yielding bias of the spring 51 so as to come to rest in the operating position of FIG. 9 in engagement with said brush elements Si) one each respectively with a brush-engaging side surface 11a, 12a. Obviously, travelling movements may now be imparted to the miniature vehicle by merely connecting the lead wires 14 to a suitable source of power.
