Adjustable three-point arrow rest for a compound archery bow

机译:可调式三点箭架,用于复合弓箭

摘要

A three-point arrow rest includes a yoke, upper and lower apertures extending through the yoke, and upper and lower parallel pivot shafts which respectively extend through the apertures. The lower pivot shaft includes first and second parallel support arms, each of which includes a support ball at a terminal end thereof. The support balls are positioned in closely spaced adjacent relation so they cooperate to receive and support an arrow shaft therebetween. The upper pivot shaft includes a guide arm which includes a guide ball at a terminal end thereof. The guide ball is positioned above and between the support balls so as to form a triangle with the support balls. The arrow rest further includes a cam and spring arrangement on each of the upper and lower pivot shafts for respectively biasing the support balls upwardly to a launching position and the guide ball downwardly to a guide position. The arrow rest still further includes a cam and screw arrangement on each of the upper and lower pivot shafts for respectively adjusting the vertical launching position of the support balls and the vertical guide position of the guide ball. The yoke is mounted onto the handle portion of a bow so that the support balls and the guide ball are generally positioned to receive and support a nocked arrow.
