Abstract

An ice scratcher for attachment to a snowmobile has a first ice scratcher end, a second ice scratcher end opposite the first ice scratcher end, a first coil spring having a first spring axis disposed at or near the first ice scratcher end, a first elongated member having a first end connected to the first coil spring, a second coil spring connected to a second end of the first elongated member, the second coil spring having a second spring axis, and a second elongated member having a first end connected to the second coil spring and a second end at or near the second ice scratcher end. Alternative embodiments of the ice scratcher are disclosed. A snowmobile having the ice scratcher is also disclosed.

Claims (27)

1. An ice scratcher for attachment to a snowmobile comprising:

a first ice scratcher end;

a second ice scratcher end opposite the first ice scratcher end;

a first coil spring having a first spring axis disposed at or near the first ice scratcher end;

a first elongated member having a first end connected to the first coil spring;

a second coil spring connected to a second end of the first elongated member, the second coil spring having a second spring axis, the second spring axis being offset from the first spring axis; and

a second elongated member having a first end connected to the second coil spring and a second end at or near the second ice scratcher end.

2. The ice scratcher of claim 1 , wherein the first and second elongated members form a V-shape.

3. The ice scratcher of claim 1 , wherein, in a direction parallel to the first spring axis, the first elongated member is disposed between the first and second coil springs, and the second coil spring is disposed between the first and second elongated members.

4. The ice scratcher of claim 1 , wherein the first and second spring axes are generally parallel to each other.

5. The ice scratcher of claim 1 , wherein, when the ice scratcher is attached in an operative position to a snowmobile at rest, the second end of the second elongated member is disposed forwardly of the first spring axis, and the first spring axis is disposed forwardly of the second spring axis.

6. The ice scratcher of claim 1 , wherein, when the ice scratcher is attached in an operative position to a snowmobile at rest, the first elongated member extends downwardly and rearwardly from the first coil spring to the second coil spring and the second elongated member extends downwardly and forwardly from the second coil spring toward the second ice scratcher end.

7. The ice scratcher of claim 1 , wherein the second elongated member is bent at a bend point, the second elongated member having a first portion between the first end of the second elongated member and the bend point and a second portion between the bend point and the second end of the second elongated member;

wherein, when the first and second springs are unstressed, a first angle between the first portion and the first elongated member is greater than a second angle between the second portion and the first elongated member.

8. The ice scratcher of claim 1 , wherein the first elongated member, the second elongated member, the first coil spring and the second coil spring are integrally formed.

9. A snowmobile comprising:

a frame including a tunnel;

at least one ski operatively connected to the frame;

a seat disposed on the tunnel;

an engine connected to the frame;

an endless track disposed at least in part under the tunnel and operatively connected to the engine;

a suspension assembly operatively connected to the track; and

at least one ice scratcher according to claim 1 operatively connected to one of the frame and the suspension assembly, the at least one ice scratcher having an operative position where the second ice scratcher end of the at least one ice scratcher is in contact with a surface on which the snowmobile operates at a position laterally outward of the endless track.

10. The snowmobile of claim 9 , further comprising at least one bracket connected to the tunnel;

wherein the first ice scratcher end of the at least one ice scratcher is connected to the at least one bracket.

11. The snowmobile of claim 9 , wherein the at least one ice scratcher is selectively movable to a stowed position where the second ice scratcher end of the at least one ice scratcher is spaced from the surface on which the snowmobile operates.

12. The snowmobile of claim 9 , wherein the at least one ice scratcher includes a left ice scratcher operatively connected to a left side of the one of the frame and the suspension assembly and a right ice scratcher operatively connected to a right side of the one of the frame and the suspension assembly.
