Compound bow with improved cam

Abstract

A compound bow comprising a handle portion having a first limb and a second limb extending outwardly therefrom, a wide body cam assembly pivotally coupled to the first limb near an outer end thereof, and a dual wheel assembly pivotally coupled to the second limb near an outer end thereof. The wide body cam assembly comprises a main sheave and a collector sheave located on opposite sides of a cable sheave. The main sheave is spaced apart from the cable sheave by a first distance sufficient to permit arrows to be fired from the bow free from interference by a cable without the use of a cable guard. The dual wheel assembly comprises a feed out sheave and a take in sheave separated by a second distance which is larger than the first distance. The feed out sheave is positioned substantially within a plane defined by the main sheave.

Description

technical field [0001] Generally, the present invention relates to the field of compound archery bows. More specifically, certain embodiments of the present invention relate to single cam type synthetic archery sport bows. Background technique [0002] Typically, a composite archery sporting bow has a bowstring on which an arrow rests, and in addition to the bowstring, one or more sections of cord also extend between the arms of the bow. Such cord portions (sometimes referred to as "power cords") typically lie at least partially at or near the operating plane of the bowstring. Therefore, the power rope may interfere with archery. [0003] In order to provide sufficient room for arrows, it is common practice to mount a rope guard on the bow so as to engage the center section of the power rope and move the center section laterally a sufficient distance to one side of the bowstring operating plane to avoid interference with the arrow . One disadvantage associated with conve...

AI Technical Summary

Problems solved by technology

One disadvantage associated with traditional rope guards is that they induce a lateral component relative to the force exerted by the power rope against the bow arm as the center of the power rope moves laterally from its straight position

This lateral moment not only reduces the accuracy of the arrow's flight, but it can also cause the arms, cams, wheels and / or handle to twist, greatly shortening their lifespan

Traditional rope guards can also cause power ropes to be installed or removed from cams and wheels at an angle

Sometimes this can cause the power cord to move out of the cam and / or wheel
