Abstract
Official abstract text for this publication.
In some embodiments, an arrow comprises a shaft, a nock and a structural asymmetry orienting a weak bending axis of the arrow.
First claim
Opening claim text (preview).
1 . An arrow comprising: a shaft; a nock; and a structural asymmetry orienting a weak bending axis of the arrow. 2 . The arrow of claim 1 , comprising a cross-section, a first half of the cross-section shaped differently from a second half of the cross-section. 3 . The arrow of claim 2 , the first half comprising the asymmetry. 4 . The arrow of claim 1 , the asymmetry extending along a length of the arrow. 5 . The arrow of claim 1 , the shaft comprising the asymmetry. 6 . The arrow of claim 5 , the asymmetry formed in an outer surface of the shaft. 7 . The arrow of claim 5 , the shaft comprising a tube, the asymmetry formed in an inner surface of the tube. 8 . The arrow of claim 5 , the shaft comprising a tube and a stiffener, the stiffener comprising the asymmetry. 9 . The arrow of claim 5 , the shaft comprising a plurality of cavities aligned in a lengthwise direction of the arrow. 10 . The arrow of claim 5 , the shaft comprising a groove. 11 . The arrow of claim 10 , an outer surface of the shaft comprising the groove. 12 . The arrow of claim 10 , an inner surface of the shaft comprising the groove. 13 . The arrow of claim 5 , the asymmetry hidden in a sidewall of the shaft. 14 . The arrow of claim 5 , the shaft comprising first fibers and second fibers arranged to provide the asymmetry. 15 . An arrow comprising: a shaft comprising a cavity; a stiffener oriented in the cavity, the stiffener comprising an asymmetrical cross-sectional shape; and a nock attached to the shaft. 16 . The arrow of claim 15 , the nock attached to the stiffener. 17 . The arrow of claim 16 , the nock comprising a notch comprising a notch axis, the stiffener comprising a strong bending axis, the strong bending axis oriented orthogonal to the notch axis. 18 . The arrow of claim 15 , the nock comprising a recess, a portion of the stiffener oriented in the recess. 19 . The arrow of claim 18 , the recess comprising a shape similar to a cross-sectional shape of the stiffener. 20 . The arrow of claim 15 , the stiffener comprising a cross-member that spans a diameter of the shaft.
