Abstract
Abstract The fifth wheel is periodically pivoted into and out of contact with the supporting surface for performing wheel stands during forward movement of the vehicle by a spring motor driven rotating crank and lever system. The front wheels of the vehicle are adjustably mounted on the side rails for changing the length of the wheel base to accommodate various body styles and models.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
164 words
In a chassis for a wheel-stand toy vehicle, a spring motor mounted on the chassis for driving the rear wheels thereof; a fifth wheel movable between a retracted position out of engagement with a supporting surface and a projected position in engagement with a supporting surface; pivoted arm means; means rotatably mounted the fifth wheel on one end of the arm means; means pivotAlly mounting the other end of the arm means on the vehicle chassis forward of the center of gravity of the vehicle; a lever rigidly fixed at one end thereof to the arm means and extending outwardly therefrom, a rotating crank operably connected with the spring motor for rotation therewith; and a connecting rod rotatably connected at one end thereof to the crank and pivotally connected at the other end thereof to the outer end of the lever for moving the fifth wheel between the retracted and the projected positions as the vehicle is being driven forward by the spring motor.
Claim 2
Dependent Claim
164 words
In a chassis for a wheel-stand toy vehicle, a spring motor mounted on the chassis for driving the rear wheels thereof; a fifth wheel movable between a retracted position out of engagement with a supporting surface and a projected position in engagement with a supporting surface; pivoted arm means; means rotatably mounted the fifth wheel on one end of the arm means; means pivotAlly mounting the other end of the arm means on the vehicle chassis forward of the center of gravity of the vehicle; a lever rigidly fixed at one end thereof to the arm means and extending outwardly therefrom, a rotating crank operably connected with the spring motor for rotation therewith; and a connecting rod rotatably connected at one end thereof to the crank and pivotally connected at the other end thereof to the outer end of the lever for moving the fifth wheel between the retracted and the projected positions as the vehicle is being driven forward by the spring motor.
Claim 3
Dependent Claim
26 words
A chassis for a wheel-stand toy vehicle according to claim 1 in which the rotating crank is connected to the winding shaft of the spring motor.
Claim 4
Dependent Claim
60 words
A chassis for a wheel-stand toy vehicle according to claim 2 in which the spring motor is mounted adjacent to rear end of the vehicle, the arm means is pivotally mounted closely adjacent the front end of the vehicle, and means provided for mounting the vehicle front axle on the forward portion of the chassis in adjusted position longitudinally thereof.
Claim 5
Dependent Claim
55 words
A chassis for a wheel-stand toy vehicle according to claim 3 in which the vehicle side rails are formed of wire, and the means adjustably mounting the vehicle front axle comprises a bracket having a first opening therein embracing each of the side rails, and a transverse opening therein mounting the vehicle front axle therein.
Claim 6
Dependent Claim
56 words
A chassis for a wheel-stand toy vehicle according to claim 4 in which said arm means is formed of wire and is of generally V-shaped configuration, said other end of the arm means is the free ends of the V-shaped wire, one free end of the wire being pivotally mounted on each of the side rails.
Claim 7
Dependent Claim
65 words
A chassis for a wheel-stand toy vehicle according to claim 2 in which the spring motor includes reduction gearing between the winding shaft thereof and the drive connection with the vehicle wheels, the driving wheels of the vehicle being rotated a plurality of times for each single rotation of the crank whereby the vehicle travels a substantial distance in the driven direction between each wheel-stand.
Claim 8
Dependent Claim
72 words
In a chassis for wheel-stand toy vehicle powered by a spring motor and having a pair of substantially parallel side rail members, a front axle support means adjustably mounted on each of the front rails adjacent the front end thereof for movement longitudinally thereof for securing the front axle of the vehicle in adjusted position relative to the rear axle thereof, and means securing the front axle support means in adjusted position.
Claim 9
Dependent Claim
72 words
In a chassis for wheel-stand toy vehicle powered by a spring motor and having a pair of substantially parallel side rail members, a front axle support means adjustably mounted on each of the front rails adjacent the front end thereof for movement longitudinally thereof for securing the front axle of the vehicle in adjusted position relative to the rear axle thereof, and means securing the front axle support means in adjusted position.
Claim 10
Dependent Claim
51 words
In a chassis for a wheel-stand toy vehicle according to claim 7 in which the side rails are formed of wire and the front axle support means each comprises a bracket having a first opening formed therein mounting the vehicle front axle, and a transverse opening therein embracing a side rail.
Claim 11
Dependent Claim
39 words
In a chassis for a wheel-stand toy vehicle according to claim 9 in which the bracket includes an integral sleeve in which the transverse opening is formed and the sleeves are soldered in adjusted position to the side rails.
Claim 12
Dependent Claim
25 words
In a chassis for a wheel-stand vehicle according to claim 1 wherein means is carried by the chassis for supporting a toy vehicle body thereon.
