Abstract

A two handed bow and a bowstring release mechanism for launching an arrow along a shooting axis includes a riser, a pair of flexible limbs mounted on the riser and a bowstring connected between the free ends of the limbs. A pair of handgrips are pivotally mounted on the riser. The bowstring release mechanism is carried by a harness adapted to be worn by the archer and includes a body member having an elongated bowstring opening for receiving the bowstring and a pair of retaining arms pivotally mounted on the body member to selectively close and open the bowstring opening. A cam and electrically operated plunger operate the retaining arms to selectively close and open the bowstring opening. A retractable arrow rest is mounted on the riser and includes a shaft engaging surface for positioning the arrow along the shooting axis when the bowstring is in its full draw position. The arrow rest is retracted away from the shooting axis by an electrically actuated mechanism such as a solenoid in response to the movement of the bowstring or to a signal delayed from the time that the bowstring is released.

Dependent claims

An archery apparatus for launching an arrow along a shooting axis comprising:

a elongated riser having limb mounting means at each end thereof and an arrow receiving opening therein;
a pair of resilient limb members, each limb member having one end thereof secured on a respective limb mounting means of the riser and a free end remote from the riser;
a bowstring connected between the free ends of the limb members and having a nocking point for engagement with the nock of an arrow;
a pair of hand grips for accommodating the left and right hands of the archer;
means for pivotally mounting the hand grips on opposite sides of the riser adjacent the arrow receiving opening, the mounting means being constructed and arranged to releasably secure the hand grips in a collapsed non-operating position along the riser in planes substantially parallel to the plane of movement of the bowstring and to releasably secure the hand grips at an acute angle .alpha. to the plane of movement of the bowstring in an operating position;
and
a harness adapted to be worn by the archer and supporting a bowstring release means thereon for selectively holding and releasing the bowstring adjacent the nocking point.

4 more elements

A bowstring release mechanism for use with one or two-handed bow comprising:

a body defining an elongated opening with an entrance for receiving the bowstring, a pair of retaining arms, each arm having first and second ends, a roller mounted on the first end of each arm, the arms being pivoted on the body for movement between a bowstring retaining position in which the rollers mounted on the first ends block the entrance to bowstring receiving opening and engage the bowstring and a bowstring release position in which the rollers mounted on the first ends are removed from the entrance to release the bowstring, and actuating means for selectively applying a force to the second ends, of the retaining arms to pivot the arms so that the rollers mounted on the first ends thereof close the entrance to the bowstring opening and for selectively removing the force from the second ends of the retaining arms to allow the rollers mounted on the first ends of the retaining arms to pivot away from the entrance to the bowstring opening.

In a retractable arrow rest for use with one or two-handed bows including a riser, a pair of resilient limbs having one end thereof secured to the riser and a free end remote from the riser and a bowstring connected between the free ends of the limbs and having a nocking point for engagement with the nock of an arrow, the bow being arranged to launch an arrow along a shooting axis upon release of the bowstring from its draw position, the combination comprising:

an arrow rest bracket mounted on the
an arrow rest bracket mounted on the riser for supporting the shaft of an arrow, the bracket having an upper shaft engaging surface and a lower end;
means for pivotally mounting the lower end of the bracket to the riser;
actuating means responsive to an electrical control signal for retracting the bracket away from the shooting axis;
and
means responsive to the release of the bowstring for generating the control signal.
