Abstract
A fall away arrow rest system for use with an archery bow. The arrow rest system includes a launcher that is adapted to support a shaft of an arrow prior to firing the arrow. Upon firing the arrow, the launcher rotates from an upright position to a lowered position to move out of the way by the time the tail region of the arrow passes by the launcher. The arrow rest system includes a rest cord coupled to the arrow rest, the effective length and tension of which determines the timing of the launcher rotating out of the way. The arrow rest system includes a system for adjusting the effective length of and tension in the rest cord to adjust the timing as desired.
Claims19
A fall away arrow rest system for use with a bow, the arrow rest comprising:
- a housing adapted for mounting to a bow;
- a rotatable shaft supported by the housing;
- a launcher coupled to the rotatable shaft and configured to receive a shaft of an arrow;
- a turn knob configured for receiving or coupling with a first end of a cord;
- a gear coupled to the rotatable shaft and including gear teeth;
- a pawl configured to engage with the gear teeth;
- and
- a biasing element that biases the pawl to engage the gear;
- wherein rotating the turn knob in a first direction about an axis of rotation results in rotation of the turn knob about the rotatable shaft without transferring rotation to the rotatable shaft;
- wherein rotating the turn knob in a second direction about the axis of rotation opposite the first direction results in the pawl engaging the gear teeth to transfer rotation of the turn knob to the rotatable shaft.
A fall away arrow rest system for use with a bow, the arrow rest comprising:
- a housing adapted for mounting to a bow;
- a rotatable shaft supported by the housing;
- a launcher coupled to the rotatable shaft and configured to receive a shaft of an arrow;
- a turn knob configured for receiving or coupling with a first end of a cord;
- a first element coupled to the rotatable shaft;
- a second element configured to engage the first element;
- and
- a biasing element that biases the second element to engage the first element;
- wherein rotating the turn knob in a first direction about an axis of rotation results in rotation of the turn knob about the rotatable shaft without transferring rotation to the rotatable shaft;
- wherein rotating the turn knob in a second direction about the axis of rotation opposite the first direction results in the first element and second element interlocking to transfer rotation of the turn knob to the rotatable shaft.
A fall away arrow rest system for use with a bow, the arrow rest comprising:
- a housing adapted for mounting to a bow;
- a rotatable shaft supported by the housing;
- a launcher coupled to the rotatable shaft and configured to receive a shaft of an arrow;
- a turn knob configured for receiving or coupling with a first end of a cord;
- a gear coupled to the rotatable shaft;
- a detent ball biased by a biasing element to engage the gear;
- and
- a set screw threaded through the turn knob and configured to engage the rotatable shaft when tightened;
- wherein rotating the turn knob about the axis of rotation without the set screw tightened results in rotation of the turn knob about the rotatable shaft without transferring rotation to the rotatable shaft;
- wherein rotating the turn knob about the axis of rotation with the set screw tightened results in rotation of the turn knob transferring rotation to the rotatable shaft;
- wherein the detent ball and biasing element are configured to bias the turn knob to one of a number of rotational positions that corresponds to the detent ball residing in a concave profile between adjacent teeth of the gear.
