Abstract
The present invention relates to methods and apparatus that may enable the folding of a multi-point compression powered archery bow. More specifically, the present invention relates to a foldable archery bow, powered by multiple compression devices, wherein the upper limb and the lower limb may be drawn independently and released together. In some aspects, the bow may be adjustable for draw weight, draw length, and draw weight let-off at full draw length in a fixable frame that may be folded and unfolded.
Claims16
An archery bow comprising:
- an upper limb;
- a lower limb;
- a grip portion for grasping the archery bow, wherein the grip portion connects the upper limb and the lower limb;
- an upper force capacitor connected to the upper limb, wherein the upper force capacitor allows for an upper let off;
- a lower force capacitor connected to the lower limb, wherein the lower force capacitor allows for a lower let off independent of the upper let off;
- a drawstring connecting the upper force capacitor and the lower force capacitor, wherein a first draw of the drawstring engages the upper force capacitor, a second draw of the drawstring engages the lower force capacitor, and a release of the drawstring releases both the first draw and the second draw;
- an upper eccentric, wherein the drawstring engages the upper force capacitor through a rotation of the upper eccentric;
- a lower eccentric, wherein the drawstring engages the lower force capacitor through a rotation of the lower eccentric;
- and
- a nock located on the drawstring configured to fit an arrow to the drawstring, wherein the nock travels a first distance during the first draw, a second distance during the second draw, and a third distance during the release, and wherein a summation of the first distance and the second distance exceeds the third distance.
