Abstract
A compound archery bow includes a power cable arranged to be taken up at one end by a pulley member and is coupled at the other end to the bow by (i) a pair of spaced-apart flexible secondary power cables connected to a transverse coupling member, and (ii) the power cable being connected to the transverse coupling member at any one of multiple cable positions along the transverse coupling member between the secondary power cables. Performance characteristics of the bow can be optimized with respect to the transverse position of the power cable on the transverse coupling member.
Claims26
A compound archery bow comprising:
- (a) a substantially rigid riser;
- (b) a first resilient bow limb extending from a first end portion of the riser;
- (c) a second resilient bow limb extending from a second end portion of the riser;
- (d) a first pulley member mounted on and rotatable relative to the first bow limb around a first transverse rotation axis, wherein the first pulley member includes a first draw cable groove and a power cable take-up mechanism;
- (e) a second pulley member mounted on and rotatable relative to the second bow limb around a second transverse rotation axis, wherein the second pulley member includes a second draw cable groove;
- (f) a draw cable engaged with the first and second draw cable grooves and arranged to rotate the first and second pulley members as the bow is drawn and the draw cable is let out from the first and second draw cable grooves;
- (g) a power cable (i) engaged to be taken up by the power cable take-up mechanism of the first pulley member as the bow is drawn and the first pulley member rotates and (ii) coupled to the bow so as to cause deformation of one or both bow limbs as the power cable is taken up;
- and
- (h) a transverse coupling member and a pair of flexible, transversely spaced-apart secondary power cables, wherein (i) the transverse coupling member is connected to the bow by the pair of transversely spaced-apart flexible secondary power cables, (ii) the power cable is connected to the transverse coupling member at any one of multiple cable positions along the transverse coupling member between the pair of secondary power cables, and (iii) the coupling member and the pair of secondary power cables are arranged so as to couple the power cable to the bow.
