## Abstract

An apparatus for one-handed operation of archery equipment may facilitate drawing and firing of an arrow from a bow. The apparatus may comprise a release aid having jaws for selective engagement and disengagement of a bowstring and a trigger mechanism operable to open and close the jaws. Head gear may be configured for attachment to the head of an archer and may be coupled to the release aid with a connection mechanism such that the archer may resist a tension in the bowstring with the headgear. An alternative apparatus comprises an automatic drawbar and engagement head such that an archer may manipulate drawbar controls to draw and release an arrow from a bow.

## Claims

### Claim 1

A method for operating an apparatus for drawing and firing an arrow from a bow, comprising:
providing an apparatus including:
a drawbar coupled to the bow, the drawbar selectively moveable between an extended configuration and a retracted configuration;
an engagement head supported by the drawbar;
a power unit operatively connected to the drawbar; and
a first drawbar control and a second drawbar control operatively connected to the power unit;
activating the first drawbar control such that the drawbar is moved from the retracted to the extended configuration when the engagement head is in an engaged configuration such that the bow may be drawn;
activating the second drawbar control such that the drawbar is moved from the engaged configuration to the release configuration when the engagement head is in a release configuration such that an arrow may be fired from the bow.

### Claim 2 (depends on 1)

The method according to claim 1, wherein the first and second drawbar controls are accessible by a hand on an extended forward arm of an archer.

### Claim 3 (depends on 1)

The method according to claim 1, wherein one of the first and second drawbar controls is accessible by a hand on an extended forward arm of an archer, and the other of the drawbar controls is configured for activation by the mouth of the archer.

### Claim 4 (depends on 1)

The method according to claim 1, further comprising a sensor electrically coupled to a control circuit, the senor configured to detect the presence or absence of an arrow from the bow, the control circuit electrically coupled to the power unit and configured to prevent accidental movement of the drawbar from the retracted configuration to the extended configuration in the absence of an arrow from the bow.

### Claim 5 (depends on 4)

The method according to claim 4, further comprising a maintenance override implement to permit the drawbar to move from the retracted configuration to the extended configuration in the absence of an arrow, and to prevent accidental movement of the engagement head from the engagement to release configuration.

### Claim 6 (depends on 1)

The method according to claim 1, wherein the drawbar is coupled to a riser of the bow.

### Claim 7 (depends on 1)

The method according to claim 1, wherein the drawbar is coupled to a cable guard of a compound bow.

### Claim 8 (depends on 1)

The method according to claim 1, wherein at least one of the drawbar, power unit and drawbar controls is selectively removable from the bow.
