## Abstract

A toy car (1) is provided which has a car box (10) on which two wheels (20) are rotatably mounted. Each wheel (20) has an eccentric disc (21) at the side facing the car box (10). The sidewalls (16) of the car box (10) have longitudinal grooves (27). These are engaged by guide cams of skid places over the corresponding wheel (20). When the car is pulled, the wheels rotate, the eccentric disc (21) moves which causes the skid to reciprocally move. The car thus simulates foot movement.

## Claims

### Claim 1

A toy car comprising:
a box;
a pair of wheels;
an axle rotatably mounted on said box and supporting said wheels on opposite sides of said box;
a first disc and a second disc eccentrically formed on an associated side of said wheels facing said box respectively;
a first pair of skids positioned over said wheels respectively, and reciprocally movable in response to said first and second discs when said wheels are rotated, an outside wall of said skids covering a major part of outside faces of said wheels wherein said skids are guided by horizontal guide elements on sides of said box for horizontal reciprocal motion.

### Claim 2 (depends on 1)

The toy car of claim 1 wherein eccentricities of said discs are offset by an angle of 180 degrees with respect to each other.

### Claim 3 (depends on 1)

The toy car of claim 1 wherein each skid has means for supporting a pin of a joint arm.

### Claim 4 (depends on 3)

The toy car of claim 3 wherein said box has coupling elements on an upper face thereof for connection with other building blocks or figures having mating coupling elements.

### Claim 5

A toy car comprising:
a box;
a pair of wheels;
an axle rotatably mounted on said box and supporting said wheels on opposite sides of said box;
a first disc and a second disc eccentrically formed on an associated side of said wheels facing said box respectively;
a first pair of skids positioned over said wheels respectively, and reciprocally movable in response to said first and second discs when said wheels are rotated, an outside wall of said skids covering a major part of outside faces of said wheels wherein said skids are guided by vertical guide elements on sides of said box for vertical reciprocal motion.

### Claim 6 (depends on 5)

The toy car of claim 5 wherein eccentricities of said discs are offset by an angle of 180 degrees with respect to each other.

### Claim 7 (depends on 5)

The toy car of claim 5 wherein each skid has means for supporting a pin of a joint arm.

### Claim 8 (depends on 7)

The toy car of claim 7 wherein said box has coupling elements on an upper face thereof for connection with other building blocks or figures having mating coupling elements.

### Claim 9

A toy car comprising:
a box;
a pair of wheels;
an axle rotatably mounted on said box and supporting said wheels on opposite sides of said box;
a first disc and a second disc eccentrically formed on an associated side of said wheels facing said box respectively;
a first pair of skids positioned over said wheels respectively, and reciprocally movable in response to said first and second discs when said wheels are rotated, an outside wall of said skids covering a major part of outside faces of said wheels wherein said box includes vertical and horizontal guide elements on each side of said box and wherein said first pair of skids is detachably mounted over said wheels and includes first engagement means for engaging said horizontal guide elements, said toy car further comprising a second pair of skids for a detachable mounting over said wheels in replacement of said first pair of skids, said second pair of skids including second engagement means for engaging said vertical guide elements.

### Claim 10 (depends on 4)

The toy car of claim 4 wherein eccentricities of said discs are offset by an angle of 180 degrees with respect to each other.

### Claim 11 (depends on 4)

The toy car of claim 4 wherein each skid has means for supporting a pin of a joint arm.

### Claim 12 (depends on 11)

The toy car of claim 11 wherein said box has coupling elements on an upper face thereof for connection with other building blocks or figures having mating coupling elements.
