Abstract
Abstract A traction cleat for a snowmobile drive belt which provides for resistance to slippage in both the longitudinal and transverse direction relative to the snowmobile and which comprises a base with longitudinal, latitudinal, and vertical dimensions, and a plurality of projections which (1) are integral with said base, (2) all extend in the same and vertical direction from said base, and (3) are spaced along the longitudinal dimension of said base, said projections being aligned longitudinally relative to said base such that there are at least two longitudinal alignments of projections with the projections of at least one of said alignments being at an angle of less than 90* relative to the longitudinal-latitudinal plane of said base; and a drive belt with said cleats attached thereto.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
102 words
A cleat for a traction drive belt of a snowmobile comprising a channel-shaped structure having a substantially planar base; a pair of legs formed integral with and extending outwardly from said base on oppositely disposed longitudinal sides of said base, at least one of said legs and the outer edge thereof having an undulating configuration along the longitudinal length thereof; and at least one projection integrally formed with and extending from at least one leg having said undulating configuration at the edge of said leg opposite to that contacting said base, said projection extending beyond the outer edge portion of said leg.
Claim 2
Dependent Claim
102 words
A cleat for a traction drive belt of a snowmobile comprising a channel-shaped structure having a substantially planar base; a pair of legs formed integral with and extending outwardly from said base on oppositely disposed longitudinal sides of said base, at least one of said legs and the outer edge thereof having an undulating configuration along the longitudinal length thereof; and at least one projection integrally formed with and extending from at least one leg having said undulating configuration at the edge of said leg opposite to that contacting said base, said projection extending beyond the outer edge portion of said leg.
Claim 3
Dependent Claim
28 words
The cleat of claim 1 in which each of said legs has an undulating configuration and there are a plurality of projections extending from each of said legs.
Claim 4
Dependent Claim
29 words
The cleat of claim 2 in which each of the oppositely disposed longitudinal sides of said base are formed into a plurality of smooth curves in the longitudinal direction.
Claim 5
Dependent Claim
63 words
The cleat of claim 3 in which the outer faces of said legs extending from said base undulate with the curved sides at the junction area of said base and legs, the undulating faces extending to the outwardly extending edges of said legs so that said legs and edges thereby undulate toward and away from a longitudinally extending plane normal to said base.
Claim 6
Dependent Claim
27 words
The cleat of claim 4 in which the offset distance of adjacent undulations from said plane are greater than the thickness of the material of said legs.
Claim 7
Dependent Claim
49 words
A traction drive belt comprising a belt with a plurality of the traction cleats of claim 1 attached thereto, said traction cleats being spaced along the longitudinal dimension of the belt with the longitudinal side of said base of said cleats corresponding to the lateral dimension of the belt.
Claim 8
Dependent Claim
49 words
A traction drive belt comprising a belt with a plurality of the traction cleats of claim 2 attached thereto, said traction cleats being spaced along the longitudinal dimension of the belt with the longitudinal side of said base of said cleats corresponding to the lateral dimension of the belt.
Claim 9
Dependent Claim
49 words
A traction drive belt comprising a belt with a plurality of the traction cleats of claim 3 attached thereto, said traction cleats being spaced along the longitudinal dimension of the belt with the longitudinal side of said base of said cleats corresponding to the lateral dimension of the belt.
Claim 10
Dependent Claim
49 words
A traction drive belt comprising a belt with a plurality of the traction cleats of claim 4 attached thereto, said traction cleats being spaced along the longitudinal dimension of the belt with the longitudinal side of said base of said cleats corresponding to the lateral dimension of the belt.
Claim 11
Dependent Claim
49 words
A traction drive belt comprising a belt with a plUrality of the traction cleats of claim 5 attached thereto, said traction cleats being spaced along the longitudinal dimension of the belt with the longitudinal side of said base of said cleats corresponding to the lateral dimension of the belt.
