Abstract
A dry fire prevention safety mechanism for crossbows having a trigger mechanism which releases a bowstring to discharge an arrow. A spring-loaded catch arm is pivotally connected to the crossbow and has a hook at one end and a ramp portion at the opposite end which extends into an arrow seating well. When an arrow is positioned to be discharged, the ramp portion is abutted by the arrow which disengages the hook from the trigger and enables operation of the crossbow.
Claims8
A safety mechanism for preventing dry fire of a crossbow having a bow mounted on a crossbow stock and a trigger mechanism for releasing a bowstring to discharge an arrow, said safety mechanism comprising:
- a catch arm pivotally connected to said crossbow stock, said catch arm having a first catch element for releasably engaging a second catch element of said trigger mechanism to prevent operation thereof, and an arrow contacting surface which pivots said first catch element out of engagement with said second catch element when an arrow is positioned to be discharged;
- and
- resiliently biasing means for urging said first catch element to releasably engage said second catch element of said trigger mechanism when no arrow is positioned to be discharged.
