Abstract
A trigger mechanism for use in a crossbow having a bowstring, the trigger mechanism comprising a housing, a trigger lever at least partially received in the housing and pivotally mounted thereto, a sliding block comprising a recess formed in a first surface, and a bowstring catch pivotally mounted in the housing. The bowstring catch has a first end configured to retain the bowstring in the housing when the crossbow is in a cocked position, and a second end that is configured to engage with the trigger lever. The sliding block is moveable between a safety on first position that prevents the trigger lever from rotating, a safety off second position where the trigger lever may be rotated, and a disarm position where a second arm of the trigger lever is partially received in the sliding block recess and a first arm of the trigger lever disengages from the bowstring catch.

10. A crossbow and trigger mechanism comprising:
-
a. a body having a first end and a second end and an axis extending from the first end to the second end; b. a first limb comprising a first end coupled to the body first end and a second end; c. a second limb comprising a first end coupled to the body first end and a second end; d. a bowstring having a bowstring first end coupled to the first limb second end and a bowstring second end coupled to the second limb second end; and e. a trigger mechanism operatively coupled to the body intermediate the body first end and the body second end, the trigger mechanism comprising; i. a trigger lever pivotally coupled to the body, the trigger lever comprising; a trigger that partially extends from the body; a trigger first arm; and a trigger second arm; ii. a sliding block that is slidably mounted at least partially within the body; iii. a lever pivotally mounted at least partially in the body, the lever comprising a first end and a second end that is operatively coupled to the body by a spring and an axis that extends from the first end to the second end; and iv. a bowstring catch pivotally mounted at least partially in the body, the bowstring catch having a first end configured to retain the bowstring when the crossbow is in a cocked position and a second end that is configured to engage with the trigger first arm when the crossbow is in the cocked position, wherein when the sliding block is moved into a disarm position; the sliding block engages the lever first end thereby causing the lever to rotate; the lever second end engages the trigger second arm causing the trigger lever to rotate; the trigger first arm moves out of engagement with the bowstring catch second end, thereby allowing the bowstring catch to rotate so that the bowstring can be released from the trigger mechanism without the user having to fire the crossbow, and wherein the sliding block further comprises a recess in a bottom surface, wherein when the sliding block is moved into the disarm position, the sliding block recess aligns with the trigger second arm such that a portion of the trigger second arm is received in the sliding block recess thereby allowing the trigger lever to rotate. - View Dependent Claims (11)

13. A crossbow and trigger mechanism comprising:
-
a. a body having a first end and a second end; b. a first limb comprising a first end coupled to the body first end and a second end; c. a second limb comprising a first end coupled to the body first end and a second end; d. a bowstring having a bowstring first end coupled to the first limb second end and a bowstring second end coupled to the second limb second end; and e. a trigger mechanism operatively coupled to the body intermediate the body first end and the body second end, the trigger mechanism comprising; i. a housing comprising; at least one cavity therein; and a first slot formed through a first side; ii. a trigger lever at least partially received in the housing and pivotally mounted to the housing, the trigger lever comprising a trigger that partially extends out from the housing; iii. a bowstring catch pivotally mounted in the housing and operatively coupled to the trigger lever, wherein a portion of the bowstring catch extends into the first slot; and iv. a disarm mechanism mounted in the housing and operatively coupled to the trigger mechanism, f. the trigger level further comprises; i. a trigger first arm; and ii. a trigger second arm; g. the disarm mechanism further comprises; i. a sliding block at least partially received in the housing; and a lever pivotally mounted in the housing; and h. a spring having a first end coupled to the housing and a second end operatively coupled to one of; i. a portion of the trigger second arm, wherein the spring is configured to bias the trigger second arm so that the trigger first arm engages with the bowstring catch second end; ii. the lever proximate the lever first end, wherein the spring biases an axis of the lever into a substantially perpendicular orientation with respect to a first surface of the sliding block when the lever is in a resting position and when the sliding block moves from the firing first position into the disarm second position, a portion of the trigger second arm is received in a recess formed in the sliding block first surface;
oriii. the bowstring catch so that the spring biases the bowstring catch second end out of engagement with the trigger first arm. wherein the disarm mechanism is configured so that when a cocking rope is used to move the bowstring into a cocked position, the cocking rope is operatively coupled to the disarm mechanism to prevent the disarm mechanism from moving into a disarm position, the bowstring catch comprises a first end configured to retain a bowstring in the housing slot when the crossbow is in a cocked position and a second end that is configured to engage with the trigger first arm when the crossbow is in the cocked position; and the sliding block is moveable between; a firing first position in which the trigger lever can rotate to disengage from the bowstring catch when a user depresses the trigger; and a disarm second position in which; the portion of the disarm mechanism is positioned within the housing first recess; and the sliding block engages a first end of the lever causing a second end of the lever to engage with the trigger second ann so that the trigger lever automatically rotates causing the trigger first arm to disengage from the bowstring catch second end. - View Dependent Claims (14, 15, 16, 19, 20, 21, 24)
