Snowmobile track cleat stud

Claim 2

A studded cleat for a snowmobile endless driving track, comprising in combination: a. a channellike cleat secured upon the outer surface of the track with the longitudinal dimension of the channel extending along a line transverse to the intended direction of movement of the snowmobile; b. a stud for use with the cleat, comprising: 1. a bottom wall parallelly arranged with respect to the bottom of the channel within the channel; 2. a pair of parallelly disposed sidewalls integrally formed with opposing ends of the bottom wall in a manner to extend outwardly at right angles to the bottom wall in a direction away from the track and along a line transverse to the intended direction of movement of the snowmobile, the length of the stud along a line parallel to the intended direction of motion of the snowmobile being substantially equal to the distance between the channel walls whereby the walls of the channel prevent displacement of the stud on the cleat in a direction parallel to the intended direction of motion of the snowmobile, the height of the stud in a direction at right angles to the bottom of the channel being greater than the depth of the channel such that the sidewalls extend outwardly from the outer surface of the track a greater distance than the channel walls, the sidewalls of the stud further including a portion broadly tapered along a line transverse to the intended direction of motion of the snowmobile whereby the stud may dig into the ice and snow to aid in providing forward motion of the snowmobile and at the same time limit lateral sliding of the snowmobile without sudden or abrupt grabbing in attaining traction; and c. means for securing said stud in said channel.

Claim 3

The device of claim 1 in which at least one sidewall of each stud includes a double taper forming a point along the outer edge of the sidewall furthermost from the track.

Claim 4

a pair of parallelly disposed sidewalls integrally formed with opposing ends of the bottom wall in a manner to extend outwardly at right angles to the bottom wall in a direction away from the track and along a line transverse to the intended direction of movement of the snowmobile, the length of the stud along a line parallel to the intended direction of motion of the snowmobile being substantially equal to the distance between the channel walls whereby the walls of the channel prevent displacement of the stud on the cleat in a direction parallel to the intended direction of motion of the snowmobile, the height of the stud in a direction at right angles to the bottom of the channel being greater than the depth of the channel such that the sidewalls extend outwardly from the outer surface of the track a greater distance than the channel walls, the sidewalls of the stud further including a portion broadly tapered along a line transverse to the intended direction of motion of the snowmobile whereby the stud may dig into the ice and snow to aid in providing forward motion of the snowmobile and at the same time limit lateral sliding of the snowmobile without sudden or abrupt grabbing in attaining traction; and c. means for securing said stud in said channel.

Claim 5

a pair of parallelly disposed sidewalls integrally formed with opposing ends of the bottom wall in a manner to extend outwardly at right angles to the bottom wall in a direction away from the track and along a line transverse to the intended direction of movement of the snowmobile, the length of the stud along a line parallel to the intended direction of motion of the snowmobile being substantially equal to the distance between the channel walls whereby the walls of the channel prevent displacement of the stud on the cleat in a direction parallel to the intended direction of motion of the snowmobile, the height of the stud in a direction at right angles to the bottom of the channel being greater than the depth of the channel such that the sidewalls extend outwardly from the outer surface of the track a greater distance than the channel walls, the sidewalls of the stud further including a portion broadly tapered along a line transverse to the intended direction of motion of the snowmobile whereby the stud may dig into the ice and snow to aid in providing forward motion of the snowmobile and at the same time limit lateral sliding of the snowmobile without sudden or abrupt grabbing in attaining traction; and c. means for securing said stud in said channel.

Claim 6

The device of claim 2, in which: a. the bottom wall includes a hole; and b. the means for securing said stud in said channel comprises at least one rivet.

Claim 7

A one-piece stud for use on a snowmobile endless driving track, either with or without a cleat, comprising: a. a bottom wall having at least four ends parallelly arranged with respect to the surface of the track, the bottom wall including a hole to allow detachment of the stud to the track; b. a first pair of parallelly disposed sidewalls integrally formed with a first pair of opposing ends of the bottom in a manner to extend outwardly at right angles to the bottom wall away from the outer surface of the track and along a line transverse to the intended direction of motion of the snowmobile, the first pair of sidewalls further including a broadly tapered portion, with the tAper extending along a line transverse to the intended direction of motion of the snowmobile; and c. a second pair of parallelly disposed sidewalls integrally formed with a second pair of opposing ends of the bottom wall in a manner to extend outwardly at right angles to the bottom wall away from the outer surface of the track and along a line parallel to the intended direction of motion of the snowmobile, the walls further including a broadly tapered portion, with the taper extending along a line parallel to the intended direction of motion of the snowmobile; whereby the stud may be directly secured to a track member such that if the stud tends to rotate upon the track member, there will always be two side portions substantially parallel to the intended direction of motion of the snowmobile and two side portions substantially transverse to the intended direction of motion of the snowmobile to provide forward traction and to limit lateral sliding of the snowmobile without sudden or abrupt grabbing in attaining traction.

Claim 8

A one-piece stud for use on a snowmobile endless driving track, either with or without a cleat, comprising: a. a bottom wall having at least four ends parallelly arranged with respect to the surface of the track, the bottom wall including a hole to allow detachment of the stud to the track; b. a first pair of parallelly disposed sidewalls integrally formed with a first pair of opposing ends of the bottom in a manner to extend outwardly at right angles to the bottom wall away from the outer surface of the track and along a line transverse to the intended direction of motion of the snowmobile, the first pair of sidewalls further including a broadly tapered portion, with the tAper extending along a line transverse to the intended direction of motion of the snowmobile; and c. a second pair of parallelly disposed sidewalls integrally formed with a second pair of opposing ends of the bottom wall in a manner to extend outwardly at right angles to the bottom wall away from the outer surface of the track and along a line parallel to the intended direction of motion of the snowmobile, the walls further including a broadly tapered portion, with the taper extending along a line parallel to the intended direction of motion of the snowmobile; whereby the stud may be directly secured to a track member such that if the stud tends to rotate upon the track member, there will always be two side portions substantially parallel to the intended direction of motion of the snowmobile and two side portions substantially transverse to the intended direction of motion of the snowmobile to provide forward traction and to limit lateral sliding of the snowmobile without sudden or abrupt grabbing in attaining traction.

Claim 9

The device of claim 4, wherein each sidewall includes a double taper forming a point along the edge of the sidewall furthermost from the track.

Claim 10

The device of claim 6 in which: a. the bottom wall comprises a square; and b. the width of all sidewalls is substantially equal whereby a regular stud is formed which better provides uniformity of performance.
