## Abstract

An endless track particularly useful in conjunction with a light-weight track vehicle. The novel track includes endless belt and a plurality of cleats fastened to and spaced about the endless belt. The cleats include rollers to provide the vehicle with agility, ease of operation and reduced turning power.

## Claims

### Claim 1

An endless track for a track vehicle, comprising:
endless belt means; and
a plurality of cleat means fastened to and spaced about said endless belt means, each of said cleat means including roller means oriented for rotation about an axis parallel to the longitudinal axis of said endless belt and traction increasing elastomeric pad means mounted transversely and forwardly of said roller means, said endless belt means comprising an inner layer of hook-loop-type fasteners and an outer layer bonded thereto, said outer layer including a length of a suitable strong flexible material and a short length of complementary hook-loop-type fasteners, said inner and outer layers being the same length, wherein the opposing free ends of said bonded layers are overlapped to connect said hook-loop-type portions to form said endless belt means.

### Claim 2 (depends on 1)

An endless track according to claim 1, wherein said cleat means is in the form of an E-shaped body including a base and three upstanding flanges integral with said base and defining leading and trailing compartments, wherein said pad is attached to the free end of the leading flange and wherein said roller means is located in said trailing compartment.

### Claim 3 (depends on 2)

An endless track according to claim 2, wherein said roller means comprises a pair of horizontally aligned rubber surfaced rollers extending somewhat proud of the free ends of said flanges such that the roller surface and the pad surface are in substantially the same plane.

### Claim 4 (depends on 3)

An endless track according to claim 3, wherein said upstanding flanges are trapezium shaped.

### Claim 5 (depends on 1)

An endless track according to claim 1, wherein said outer layer includes a plurality of substantially equally spaced upstanding loop means and wherein the base of said cleat means includes a central transverse opening, such that said loop means extends through said opening and further comprising wedge means for retaining said loop means in said opening to fasten said cleat means to said endless belt means.

### Claim 6 (depends on 1, 5)

An endless track according to claim 1 or 5, wherein said strong flexible material is nylon.

### Claim 7 (depends on 1, 2, 5)

An endless track according to claim 1, 2 or 5, wherein said cleat means are constructed of a suitable hard plastics material.

### Claim 8 (depends on 1, 2, 5)

An endless track according to claim 1, 2 or 5, wherein said cleat means are constructed of polycarbonate.

### Claim 9 (depends on 1)

An endless track according to claim 1 in which the pads are mounted stationary in relation to the rollers.
