US4155554A — Miniature target tank

Claim 1

Independent Claim 328 words

A three-wheeled miniature target vehicle comprising in combination: a vehicle body structural component consisting of a sheet metal box (13), and an elongated tube (15) extending from the box in a forward direction; ground wheel means comprising a pair of live powered rear wheels (14) having fixed axis drive axles extending into the box, and a single front steered wheel (14) having a caster leg (72) swivel-connected to the forward end of the aforementioned tube; means for powering and steering the vehicle comprising a servo-activating radio receiver (50), a propulsion servo motor and propulsion motor means (36) controlled by said servo motor, a steering servo motor (52), and battery means arranged to energize said radio receiver, two servo motors and propulsion motor means; said receiver, two servo motors and propulsion motor means being disposed entirely within the sheet metal box, and said box being formed of armor plate for shielding the box contents against damage by bullets fired at the vehicle; the means for steering the vehicle further comprising a force-transmitting connection between the steering servo motor and the aforementioned caster leg at the forward wheel; said force-transmitting connection comprising a first crank arm (64) driven by the steering servo motor, a second crank arm (68) connected to the caster leg, and an elongated connecting rod (66) operatively connecting the two crank arms, said rod being disposed within said tube whereby the tube protects the rod against damage by bullets fired at the vehicle; and an expendable ornamental shell simulating the external contour of a military vehicle; said shell including a roof section resting on the vehicle body component, and a downwardly-extending skirt section circumscribing the ground wheel means; the aforementioned tube (15) having its rear end anchored to the box at a point midway between the box front and rear walls; said tube extending forwardly from its anchorage point through a notch in the box front wall so that the tube and box form one rigid assembly.

Claim 2

Dependent Claim 328 words

A three-wheeled miniature target vehicle comprising in combination: a vehicle body structural component consisting of a sheet metal box (13), and an elongated tube (15) extending from the box in a forward direction; ground wheel means comprising a pair of live powered rear wheels (14) having fixed axis drive axles extending into the box, and a single front steered wheel (14) having a caster leg (72) swivel-connected to the forward end of the aforementioned tube; means for powering and steering the vehicle comprising a servo-activating radio receiver (50), a propulsion servo motor and propulsion motor means (36) controlled by said servo motor, a steering servo motor (52), and battery means arranged to energize said radio receiver, two servo motors and propulsion motor means; said receiver, two servo motors and propulsion motor means being disposed entirely within the sheet metal box, and said box being formed of armor plate for shielding the box contents against damage by bullets fired at the vehicle; the means for steering the vehicle further comprising a force-transmitting connection between the steering servo motor and the aforementioned caster leg at the forward wheel; said force-transmitting connection comprising a first crank arm (64) driven by the steering servo motor, a second crank arm (68) connected to the caster leg, and an elongated connecting rod (66) operatively connecting the two crank arms, said rod being disposed within said tube whereby the tube protects the rod against damage by bullets fired at the vehicle; and an expendable ornamental shell simulating the external contour of a military vehicle; said shell including a roof section resting on the vehicle body component, and a downwardly-extending skirt section circumscribing the ground wheel means; the aforementioned tube (15) having its rear end anchored to the box at a point midway between the box front and rear walls; said tube extending forwardly from its anchorage point through a notch in the box front wall so that the tube and box form one rigid assembly.

Claim 3

Dependent Claim 43 words

The vehicle of claim 1: said tube having a bolt-type anchorage connection (56) with the box; said steering servo motor being suspended from the tube within the box, whereby the tube and steering servo motor can be removed and replaced as a unit.

Claim 4

Dependent Claim 75 words

The vehicle of claim 1: said tube having a bracket at its forward end defining a first upwardly facing mount surface; said box having a flange at its rear end defining a second upwardly facing mount surface; said ornamental shell having roof surfaces thereof adapted to seat on said first and second mount surfaces; and bolt means extending through the shell into the mount surfaces to releasably retain the shell on the vehicle body component.

Claim 5

Dependent Claim 44 words

The vehicle of claim 1: said box including a front wall having a forwardly extending flange at its upper end; and a radio receiver antenna mounted on said flange in a vertical attitude; the ornamental shell having an opening therein for accommodating the antenna.
