1 Claim. (@l. 188-409) This invention relates to new and useful improve ments in toy cars for children to ride and propel.

More particularly, the present invention proposes the construction of an improved maneuverable hand-operated toy car which a child can easily and safely use for coasting, pushing and self-propelling.

As a further object, the present invention proposes forming the car with a chassis having a main set of drive wheels and front and rear swivel caster wheels with three different brakes for braking the main wheels. Itis also an object of the invention to provide a hand operated toy car having two main drive wheels with means for driving each wheel independently of the other whereby greater maneuverability is produced.

Another object of the invention proposes constructing one of the brakes as a seat operated brake which will always be on when the seat of the car is unoccupied so as to permit thecar safely to be parked on inclines and in places when it is likely to roll or be pushed.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings, and to the appended claims in which the various novel features of the invention are more particularly set forth.

In the accompanying drawings forming a material part of this disclosure:

Fig. 7 is a view similar to Fig. 5 but illustrating another modification.

Fig. 8 is a side view of the structure shown in Fig. 7.

Fig. 9 is a perspective view of the seat bracket shown in Figs. 7 and 8.

The toy car, in accordance with the first form of the invention shown in Figs. 1 to 5, inclusive, has a chassis 15 which may be made of structural metal members and which preferably is made in the shape shown.

Chassis 15 has a front end 16 and a rear end 17 and a resilient rubber bumper 18 entirely encircles the chassis or frame. A pair of spaced main drive wheels 19 and 20 are rotatably mounted on the ends of a main axle 21 by means of laterally extending tubular hub extensions 19 and 26' respectively. The axle 21 is fixedly mounted on the chassis by brackets 22 between the front and rear ends of the chassis. Front and rear caster wheels 23 and 24 are swivelly mounted on the chassis at the front end 16 and rear end 17, respectively.

2,869,686 Patented Jan. 20, 1959 ice Two pairs of spaced upright crank supports 25, 26, 27 and 28 covered by appropriate shields or covers 27' and 28' are mounted on the'chassis and a pair of pillow blocks 25 and 26 are mounted at the top of the crank supports 25 and 26. Stub axles 29 and 30 rotatably extend through the pillow blocks and crank supports. Crank disc 31 is fixed to the stub axle 29 and crank 32 is fixed to the crank disc. Likewise, a crank disc 33 is fixed to the stub axle 30 and a crank 34 is fixed to the crank disc 33. Cranks 32 and 33 are opposed and disposed for convenient independent operation by a child from a sitting position. A sprocket 35 is fixedly mounted on the hub extension 19' of the drive wheel 19, and a sprocket 36 is fixedly mounted on the stub axle 29. A chain 37 connects the sprockets 35 and 26. Likewise, a sprocket 38 is fixedly mounted on the hub extension 20' of the drive wheel 20, and a sprocket 39 is fixedly mount ed on the stub shaft 30, with a chain 40 connecting these sprockets. This construction permits .independent driving of the drive wheels 19 and 20 by the cranks 32 and 34, respectively.

A seat 41 is pivotally mounted on the floor 42 of the chassis and a seat operated brake 43 is mounted on the chassis adjacent the main wheels and connected with the seat to prevent the main wheels from rotating when the seat is not occupied. The seat and main wheels are loend 52 connected to the chassis and another end 53 to which the brake lever arm 45 is pivotally connected by pin 54. The pivot pin 54 is located between the ends 47 and 48 of the brake lever arm 45.

A resilient member or spring 55 is disposed between the seat 41 and the chassis normally to bias the seat in a tilted position and through the seat and brake lever arms 44 and 45 to force the brake shoe portion 47 of the brake lever arm 45 against one of the main wheels.

The seat 41 is partially enclosed by a seat enclosurej An externally operated brake lever 57 is pivotally mounted. at one end 56 which forms the body of the car.

58 to the chassis at the rear end of the chassis. Adjacent the end 58 of brake lever 57, one end 59 of a connecting rod 6% is attached. A brake bearing block lever 61 is pivotally dependent from the chassis adjacent one of the main wheels, lever 61 having one end 62 pivotally connected to the chassis. The connecting rod 60 has another end 63 connected to the brake bearing block lever for operating that lever by the externally operated brake lever 57.

A foot trip release 64 is pivotally connected to the chassis adjacent the externally operated brake lever 57 for blocking and releasing the lever 57.

A foot brake 65 is mounted on the front end of the chassis adjacent a foot rest 66. The foot brake 65 has a pedal 67 pivotally mounted on the chassis and a tie rod 68 connects the pedal with the brake bearing block lever 61 for pressing the lever 61 against one of the main wheels when the pedal is depressed. A spring 69 normally holds the pedal in unpivoted position and the brake bearing block lever out of contact with the main wheel.

The modification of the invention illustrated in Fig. 6 is characterized by the provision of a frame or chassis 70 having a seat 71 pivotally mounted thereon and a seat operated brake 72. The seat operated brake 72 has a seat lever arm 73, a fixed chassis connecting arm '74 and a brake lever arm 75. The brake lever arm 75 has a brake shoe 76 and a shank member '77, the shank member having an end 78 pivotally connected by pin 79 to the seat lever arm 73 and another end 80 pivotally connected by pin 81 to the brake shoe intermediate the ends 82 and 83 of the brake shoe. The brake shoe 76 is also pivotally connected by pin 81 to the fixed chassis connecting arm 74. A spring 84 connected to the shank member and to the end 83 of the brake normally biases the end 82 of the brake shoe in pivoted position toward the main wheel 85.

A screw member 86 is mounted on the shank member 77. Screw member 86 has a tubular threaded housing 87 fixed to the shank member and a screw 88 with wing nut head 89 fits in the housing and bears against the end 83 of the brake shoe between the spring 84 and pivot pin 81 to counteract as desired the action of the spring and hold the brake shoe away from the Wheel 85. A spring 90 normally biases the seat 71 in the raised tilted position shown.

The modification of the invention illustrated in Figs. 7, 8 and 9 is characterized by the provision of a pipe or tubular frame or chassis 92 preferably made of one-half inch diameter hollow aluminum tubing made in two lengths 93 and 94 and joined together by connector members'95 and 96 at the front and back of the frame respectively.

Swivel caster road steering wheels 97 and 98 are rotatably and swivelly mounted on the connector members and 96, respectively. A seat bracket 99 extends upwardly from the rear connector member 96 and a seat 100 is mounted on the seat bracket, with a back rest 1013. are mounted on the frame lengths 93 and 94 by clamps 103 and are secured to the seat 100 by bolts or screws 104.

Chain guards 101 and 102 house chains 105 and 106 extendnig between sprockets 107 and 108 and 109 and 110. A main axle 111 is fixedly mounted on the frame and main drive wheels 112 and 113 are rotatably mounted on the main axle by means of hub extensions 112' and 113'. Sprockets 107 and 109 are fixedly mounted on the hub extensions, and sprockets 108 and are fixedly mounted on stub axles 114 and 115 rotatably mounted on the supports 101 and 102, respectively. Crank discs 116 and 117 are mounted on the stub axles 114 and 115 respectively, and crank handles 118 and 119 are secured to the crank discs, whereby the drive Wheels 112 and 113 are independently driven.

While I have illustrated and described the preferred embodiments of my invention, it is to be understood Chain guards and crank supports 101 and 102 4 that I do not limit myself to the precise constructions herein disclosed and that various changes and modifications may be made within the scope of the invention as defined in the appended claim.
