Compound archery bow with extended inverted stroke
First Claim
1. A compound archery bow comprising:
- a riser supporting a member for gripping the bow;
first and second limbs each extending in a forward direction from the riser to a distal end spaced apart from the riser;
pulley means disposed adjacent to the distal end of each limb;
a first cam and a second cam mounted with respect to the riser and rotatable on respective axes of rotation;
a bowstring extending between the pulley means on each limb so that the bowstring may be drawn on a path between a forward position and a rearward position;
one end of the bowstring extending from the pulley means on the first limb to the first cam, and another end of the bowstring extending from the pulley means on the second limb to the second cam;
a first cable extending from the first cam to the pulley means on the first limb, and thence extending to the second limb; and
a second cable extending from the second cam to the pulley means on the second limb, and thence extending to the first limb,whereby drawing the bowstring toward the rearward position rotates the cams and thereby causes the cables to wind onto the cams and compress the limbs, producing limb tension that acts through the cams and pulley means to propel an arrow from the bow when the bowstring is released.

Abstract
An inverted compound archery bow including an extended-capacity cam system having two cams, each cam engaging the bowstring and separate cables extending to limbs of the bow. The bowstring and cables are counter-wound on the cams, producing tension opposite and proportional to the inverse ratio of windings. Drawing the bowstring winds the cables onto the cams, producing limb tension that propels an arrow when the bowstring is released. An arrow rest located between full-draw and rest excursions of the bowstring accommodates the extended draw length of the bow. A bowstring arrestor engages the bowstring at an intermediate-draw position. A slide stabilizes and supports a rear portion of the bow, and a receptacle on the slide engages an adapter for a bowstring release mechanism.

10. A compound archery bow comprising:
-
a riser; limbs extending from the riser to distal ends; a bowstring having at least a portion extending between the distal ends of the limbs so that the bowstring may be drawn along a path between a forward position at rest and a full-drawn position behind the forward position; an arrow rest for supporting an arrow nocked to the bowstring as the bowstring is drawn and before the bowstring is released to propel the arrow, wherein the arrow rest is movable between a support position adjacent the path of the bowstring and an arrow so as to support the arrow before the bowstring is released, and a second position out of the path of the bowstring and the arrow when the bowstring is released for forward movement toward the arrow rest; and the arrow rest being disposed between the forward position and the full-drawn position of the bowstring. - View Dependent Claims (11, 12, 13, 14, 15)

16. A compound archery bow comprising:
-
a riser; limbs extending from the riser to distal ends; a bowstring having at least a portion extending between the distal ends of the limbs for drawing along a path between a forward position at rest and a full-drawn position behind the forward position; a bowstring arrestor associated with the riser for holding the bowstring at an intermediate position between the forward position and the full-drawn position; and an actuator, positioned on a slide rod of the riser, for automatically deploying the bowstring arrestor; the bowstring arrestor being operative to disengage the bowstring and retract from the path of the bowstring in response to drawing the slide rod back from the intermediate position, so that the retracted bowstring arrestor does not interfere with forward movement of the bowstring upon release of the bowstring. - View Dependent Claims (17)

18. An archery bow, comprising:
-
a riser; limbs extending from the riser; a bowstring having at least a portion extending between the limbs for drawing along a path between a forward position at rest and a frill-drawn position behind the forward position; a support member associated with the riser for selective rearward and forward movement laterally offset from the path of the bowstring; an arm laterally extending from the support member for positioning behind the full-drawn position of the bowstring as the support member is moved rearwardly; and the arm having a receptacle to receive and provide lateral support to a release mechanism that draws the bowstring to the full-drawn position while the arm and the support member move rearwardly with the release mechanism; and an adapter engaging the release mechanism and having a tapered portion, wherein the receptacle of the arm having a taper complementary to the tapered portion of the adapter and engaging the adapter as the release mechanism draws the bowstring rearwardly, whereby the adapter maintains the release mechanism in spaced apart relation to the arm so as to prevent unintentional disengagement of the release mechanism from a slide mechanism.
