Abstract
An archery bow assembly is provided including an open sided spacer which is mountable to an axle on an archery bow and removable therefrom without removing the axle entirely or partially from a limb of the archery bow. The spacer can mount on the axle adjacent a cam rotatable on the axle, and can include an outer perimeter and an axle aperture. A recess can extend inward from the outer perimeter to the axle aperture so that the axle aperture and recess form a continuous opening. The spacer can be of a C-shape or E-shape so that it can be frictionally pressed onto the axle and removed therefrom without removing the axle from the limb arms adjacent the cam. Related methods also are provided.
Claims20
An archery bow assembly comprising:
- a limb defining a limb recess;
- an axle joined with the limb, the axle including a first axle end and a second axle end distal from one another;
- a cam rotatably mounted relative to the axle within the limb recess, the cam including a bowstring track;
- an open sided spacer including a body defining a longitudinal axis and an axle aperture that surrounds the longitudinal axis, the axle aperture receiving the axle between the first axle end and the second axle end, the body including an outer perimeter interrupted by a spacer recess that extends inwardly toward the longitudinal axis and the axle aperture so that the spacer recess and axle aperture form a continuous opening, the open sided spacer joined with the axle in the limb recess adjacent the cam, distal from the first axle end and from the second axle end;
- wherein the open sided spacer is mountable to the axle and removable therefrom without removing the axle from the limb.
An archery bow assembly comprising:
- a spacer body defining a longitudinal axis and including a thickness between about 0.050 inches and about 0.300 inches, the spacer body defining an axle aperture that surrounds the longitudinal axis and is configured to receive an axle of an archery bow upon which a cam rotatably mounts;
- an outer perimeter extending around the spacer body, the outer perimeter interrupted by a spacer recess that extends inwardly toward the longitudinal axis and the axle aperture so that the recess and axle aperture form a continuous opening,
- wherein the spacer body is mounted to the axle of the archery bow within a limb recess, and removable from the axle without removing the axle from a limb of the archery bow.
A method of using an archery bow assembly, the method comprising:
- providing an axle installed relative to opposing arms of a limb of an archery bow, with a cam rotatably mounted on the axle in a limb recess between the opposing arms, the axle including a longitudinal axis;
- and
- pressing an open sided spacer onto the axle within the limb recess in a direction transverse to the longitudinal axis of the axle such that the axle passes through a spacer recess until the axle enters an axle aperture of the spacer,
- wherein the open sider spacer is installed on the axle without removing the axle from the opposing arms of the limb.
