Self-actuating, dry-fire prevention safety device for a crossbow
First Claim
1. A self-actuating, dry-fire prevention device for a crossbow of the type having a trigger mechanism to release a bowstring to fire an arrow, the device comprising a movable stop block;
- means to pivot said stop block into releasable locking engagement with the trigger mechanism such that the trigger mechanism is blocked from operating to release the bowstring;
said stop block having at least one arrow contacting surface such that when an arrow is placed into position to be fired, the arrow engages said arrow contacting surface causing said stop block to move out of said locking engagement with the trigger mechanism to allow operation of the trigger mechanism and release of the bowstring.

Abstract
A self-actuating, dry-fire prevention device for a crossbow (10) includes a pivotable stop block (30) and a pivot pin (35) and a spring (41) to pivot said stop block into releasable locking engagement with the crossbow trigger mechanism (15) such that the trigger mechanism is blocked from operating to release the bowstring (43) in the absence of an arrow (40). The stop block (30) has an arrow contacting surface (50, 51) such that when the arrow (40) is placed into position to be fired, the arrow (40) engages the arrow contacting surface (50, 51) causing the stop block (30) to pivot out of locking engagement with the trigger mechanism (15) to allow operation of the trigger mechanism (15) and release of the bowstring (43).

10. A device for preventing an inadvertent activation of a trigger mechanism of a crossbow without an arrow in place comprising a stop block;
- said stop block including a body member to engage a portion of the trigger mechanism;
said body member including an arrow contacting surface which when engaged by the arrow upon placement of the arrow into position to be fired will move said body member out of engagement with the trigger mechanism. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)
- said stop block including a body member to engage a portion of the trigger mechanism;

18. A crossbow having a bowstring comprising a trigger mechanism operable to selectively hold and release the bowstring, a pivotable stop block;
- and means to pivot said stop block into releasable locking engagement with said trigger mechanism such that said trigger mechanism is blocked from operating to release the bowstring;
said stop block having at least one arrow contacting surface such that when an arrow is placed into position to be fired, the arrow engages said arrow contacting surface causing said stop block to pivot out of said locking engagement with said trigger mechanism to allow operation of the trigger mechanism and release of the bowstring. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25)
- and means to pivot said stop block into releasable locking engagement with said trigger mechanism such that said trigger mechanism is blocked from operating to release the bowstring;
