Abstract

A reach-adjustable lever assembly mounted to a handlebar for actuating one of a gear-change and braking device. The lever assembly generally including a support member, a lever pivotably connected to the support member and a reach adjust mechanism. The reach adjust mechanism includes a follower, a cam and a cam seat for retaining the cam in a current user-selectable position. The follower is fixedly supported on one of the support member and the lever and the cam is rotatably supported on the other of the support member and the lever. The cam has a plurality of user-selectable positions. The lever is rotatably biased toward a rest position to position the cam against the follower. The cam and the follower are configured to provide a different rest position of the lever for each of the user-selectable positions.

Claims

1. A reach-adjustable lever assembly mountable to a handlebar for actuating one of a gear-change and a braking device, the reach-adjustable lever assembly comprising:

a support member;

a lever pivotably connected to the support member; and

a reach adjust mechanism including;

a follower fixedly supported on one of the support member and the lever;

a cam rotatably supported on the other of the support member and the lever, the cam having a plurality of user-selectable positions; and

a cam seat for retaining the cam in one of the plurality of user-selectable positions, the cam seat including a post supported on the other of the support member and the lever, the post having an engaging portion and a non-engaging portion, the cam alternatively positionable on the post by a sliding axial movement of the cam along the post from one to the other of the engaging and non-engaging portions, the engaging portion shaped for retaining the cam in the current user-selectable position by preventing rotation of the cam when positioned thereon, the non-engaging portion shaped for permitting rotation of the cam between the user-selectable positions, the cam biased toward the engaging portion,

the lever rotatably biased toward a rest position to position the cam against the follower, the cam and the follower configured to provide a different rest position of the lever for each of the user-selectable positions.

2. A reach-adjustable lever assembly according to claim 1, wherein the follower is fixedly supported on the support member and the cam is rotatably supported on the lever.

3. A reach-adjustable lever assembly according to claim 2, wherein the cam includes a non-circular inner surface matingly engageable with a complimentary-shaped non-circular outer surface of the engaging portion of the post to prevent relative rotation between the cam and the post.

4. A reach-adjustable lever assembly according to claim 3, wherein a spring biases the cam toward the engaging portion of the post.

5. A reach-adjustable lever assembly according to claim 4, wherein a retaining ring retains the cam on the post.

6. A reach-adjustable lever assembly according to claim 5, wherein the spring is positioned between the cam and the one of the support member and the lever.

7. A reach-adjustable lever assembly according to claim 1, wherein the follower is fixedly supported on the lever and the cam is rotatably supported on the support member.
