Crossbow
First Claim
1. A crossbow trigger mechanism, comprising:
- a trigger housing for receiving a bowstring of a crossbow;
a bowstring catch mounted with respect to the housing and adapted to releasably engage a crossbow bowstring brought within the trigger housing;
a trigger adapted to releasably engage the bowstring catch, the trigger being further adapted to be selectively actuated by a user so as to cause the trigger to release the bowstring catch, thereby causing the bowstring catch to release a crossbow bowstring; and
a ball disposed between the bowstring catch and the trigger, the ball being adapted to bear and react to forces arising between the bowstring catch and the trigger during at least one of the trigger engaging the bowstring catch and the trigger releasing the bowstring catch;
wherein the ball is at least partially contained within a socket or sleeve; and
wherein the socket or sleeve extends from an end portion of the bowstring catch.

Abstract
A crossbow includes a trigger mechanism having a trigger housing for receiving a bowstring of a crossbow and a bowstring catch mounted with respect to the housing and adapted to releasably engage a crossbow bowstring brought within the trigger housing. The crossbow further includes a trigger adapted to releasably engage the bowstring catch, the trigger being further adapted to be selectively actuated by a user so as to cause the trigger to release the bowstring catch, thereby causing the bowstring catch to release a crossbow bowstring. Optionally, the crossbow may include a ball disposed between the bowstring catch and the trigger, the ball being adapted to bear and react to forces arising between the bowstring catch and the trigger during at least one of the trigger so engaging the bowstring catch and the trigger so releasing the bowstring catch.

5. A crossbow trigger mechanism, comprising:
-
a trigger housing for receiving a bowstring of a crossbow; a bowstring catch moveably mounted with respect to the housing and adapted to releasably engage a crossbow bowstring brought within the trigger housing; and a trigger, the trigger including a first trigger element adapted to releasably engage the bowstring catch, and a second trigger element adapted to rotate relative to the first trigger element and to be selectively actuated by a user to engage and impart an urging force to the first trigger element for rotating the first trigger element relative to the bowstring catch, and thereby causing the first trigger element to release the bowstring catch; wherein the first trigger element includes a reaction surface, the second trigger element includes a camming surface, and the second trigger element is adapted, while rotating relative to the first trigger element, to engage the first trigger element, and to rotate the first trigger element relative to the bowstring catch, via the camming surface imparting an urging force to the reaction surface; wherein the first trigger element includes a first body and a roller rollably mounted to the first body, wherein the reaction surface of the first trigger element is a curved reaction surface of the roller; wherein in rotating the first trigger element relative to the bowstring, the roller is caused to roll across the camming surface, and to roll relative to the first body of the trigger; wherein each of the camming surface and the reaction surface exhibits a geometry; and wherein the respective geometries of the camming surface and the reaction surface are respectively sized and shaped to match one another and functionally cooperate in allowing a user of the crossbow trigger mechanism to exert a pulling force of a substantially constant magnitude on the second trigger element, from an initial application by the user of a pulling force to the second trigger element, to an ultimate release of the bowstring catch by the first trigger element. - View Dependent Claims (6, 7, 8, 9, 10, 11, 12, 13)

14. A crossbow trigger mechanism, comprising:
-
a trigger housing for receiving a bowstring of a crossbow; a bowstring catch mounted with respect to the housing and adapted to releasably engage a crossbow bowstring brought within the trigger housing; and a dry fire stop including a first projection adapted to engage the bowstring catch for limiting a rotation of the bowstring catch away from a crossbow bowstring with which the bowstring catch is releasably engaged, and a second projection adapted to extend into a path of a crossbow bolt being loaded into the trigger housing such that as such crossbow bolt is loaded into the trigger housing, the crossbow bolt rotates the dry fire stop relative to the bowstring catch by impinging on and displacing the second projection away from the bolt loading path, thereby disengaging the first projection of from the bowstring catch and allowing rotation of the bowstring catch away from a crossbow bowstring with which the bowstring catch is releasably engaged; wherein the bowstring catch includes a recessed pocket positioned on an upper portion of the bowstring catch for receiving the first projection of the dry fire stop to facilitate the first projection engaging the bowstring catch. - View Dependent Claims (15)
