Apparatuses and Methods for Supporting Bow Limbs

Abstract

The present disclosure generally pertains to apparatuses and methods for supporting bow limbs. In accordance with one exemplary embodiment of the present disclosure, a T-shaped insert is inserted into each prong of a forked limb of an archery bow. An axle on which a cam is mounted passes through each insert in the forked limb. Each such insert helps to redistribute the load exerted by the axle in a manner so that the limb can better withstand the load thereby extending the useful life of the bow.

Description

CROSS REFERENCE TO RELATED APPLICATION[0001]This application claims priority to U.S. Provisional Patent Application No. 60 / 834,713, entitled “Apparatuses and Methods for Supporting Bow Limbs,” and filed on Aug. 1, 2006, which is incorporated herein by reference.RELATED ART[0002]Many conventional archery bows have at least one cam mounted at a respective end of a bow limb. There are generally two types of bow limbs, solid and split. In either case, the end of a bow limb supporting a cam is typically forked such that it has two prongs separated by a gap. An axle passes through each prong, and the cam is mounted on the axle between the prongs. At least one cord is secured to the cam, which rotates when a user pulls the cord. The pulling of the cord also typically deforms the bow limb. The cam can be spring-loaded such that it returns to its original position when the user releases the cord thereby launching a projectile, such as an arrow, that has been positioned against the cord. Rele...

AI Technical Summary

Problems solved by technology

Drawing of the cord by a user to launch projectiles causes significant force to be applied to the bow limb, particularly at the point where the axle passes through the limb.

Repetitive drawing of the cord causes mechanical fatigue at such point eventually resulting in mechanical failure of the bow limb.
