发明名称 COMPOUND BOWS WITH MODIFIED CAMS
摘要 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.

主权项 1. 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, the wide body cam assembly comprising a main sheave and a collector sheave located on opposite sides of a cable sheave, the main sheave spaced apart from the cable sheave by a first distance; a dual wheel assembly pivotally coupled to the second limb near an outer end thereof, the dual wheel assembly comprising 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 positioned substantially within a plane defined by the main sheave; a first bowstring portion having a nock point thereon for necking an arrow, the first bowstring portion extending from the main sheave of the wide body cam assembly to the feed out sheave of the dual wheel assembly and a second bowstring portion extending from the collector sheave of the wide body cam assembly to the take in sheave of the dual wheel assembly; and, a cable having a first end coupled to the cable sheave of the wide body cam assembly and a second end comprising a split portion coupled to a pair of attachment points on or near the outer end of the second limb on either side of the dual wheel assembly wherein the first distance is sufficient to permit arrows knocked on the first bowstring portion extending between the main sheave and the feed out sheave to be fired from the bow free from interference by a cable extending within a plane defined by the cable sheave without the use of a cable guard.
