Reduced friction trigger for a crossbow
First Claim
1. A reduced friction trigger for a crossbow having a draw string for launching arrows, the reduced friction trigger comprising:
- a catch moveable between a closed position that retains the draw string in a drawn configuration and an open position that releases the draw string to a released configuration position such that after firing the crossbow the catch is biased to the open position;
a sear moveable between a de-cocked position and a cocked position coupled with the catch at an interface to retain the catch in the closed position such that after firing the crossbow the sear is retained by a detent in the de-cocked position by the catch, the sear being biased to the cocked position by a sear biasing force;
a dry fire lockout moveable between a disengaged position upon engagement of an arrow with the draw string, and a lockout position that blocks the sear from moving to the de-cocked position when an arrow is not engaged with the draw string, such that after firing the crossbow the dry fire lockout is retained in the disengaged position by the sear while being biased to the lockout position;
a low friction device at the interface of the catch with the sear when the sear is in the cocked position; and
a trigger assembly located at a proximal end of the crossbow having a trigger positioned to move the sear from the cocked position to the de-cocked position to fire the crossbow.

Abstract
A reduced friction trigger for a crossbow including a catch moveable between a closed position that retains the draw string in a drawn configuration and an open position that releases the draw string to a released configuration position such that after firing the crossbow the catch is biased to the open position. A sear is moveable between a de-cocked position and a cocked position coupled with the catch at an interface to retain the catch in the closed position such that after firing the crossbow the sear is retained in the de-cocked position by the catch, the sear being biased to the cocked position by a sear biasing force. A low friction device is located at the interface of the catch with the sear. A force sufficient to overcome frictional forces at the interface to release the catch to the open position is less than the sear biasing force.

16. A reduced friction trigger for a crossbow having a draw string for launching arrows, the reduced friction trigger comprising:
-
a catch moveable between a closed position that retains the draw string in a drawn configuration and an open position that releases the draw string to a released configuration position such that after firing the crossbow the catch is biased to the open position; a sear moveable between a de-cocked position and a cocked position coupled with the catch at an interface to retain the catch in the closed position such that after firing the crossbow the sear is retained by a detent in the de-cocked position by the catch, the sear being biased to the cocked position by a sear biasing force; a dry fire lockout moveable between a disengaged position upon engagement of an arrow with the draw string, and a lockout position that blocks the sear from moving to the de-cocked position when an arrow is not engaged with the draw string, such that after firing the crossbow the dry fire lockout is retained in the disengaged position by the sear while being biased to the lockout position; a low friction device comprising one or more of a roller pin or ball bearings that engages with a recess in the sear at the interface when the sear is in the cocked position; and a trigger assembly located at a proximal end of the crossbow having a trigger positioned to move the sear from the cocked position to the de-cocked position to fire the crossbow.

17. A reduced friction trigger for a crossbow having a draw string for launching arrows, the reduced friction trigger comprising:
-
a catch moveable between a closed position that retains the draw string in a drawn configuration and an open position that releases the draw string to a released configuration position such that after firing the crossbow the catch is biased to the open position; a sear moveable between a de-cocked position and a cocked position coupled with the catch at an interface to retain the catch in the closed position such that after firing the crossbow the sear is retained by a detent in the de-cocked position by the catch, the sear being biases to the cocked position by a sear biasing force; a dry fire lockout moveable between a disengaged position upon engagement of an arrow with the draw string, and a lockout position that blocks the sear from moving to the de-cocked position when an arrow is not engaged with the draw string, such that after firing the crossbow the dry fire lockout is retained in the disengaged position by the sear while being biased to the lockout position; a low friction device that engages with a recess in the sear at the interface when the sear is in the cocked position, wherein a force sufficient to overcome frictional forces at the interface to release the catch to the open position is less than the sear biasing force; and a trigger assembly located at a proximal end of the crossbow having a trigger positioned to move the sear from the cocked position to the de-cocked position to fire the crossbow. - View Dependent Claims (18)
