Abstract

A crossbow, which exhibits a support (2), provided with the arrow guide, and a bow (3) which can be drawn by a string (4), is made ready for shooting by drawing device (19, 22). The drawing device consists of a draw lever (19) rotatably mounted in support (2) of the crossbow and a pusher (22) pivoted on the latter, a pusher which works with shooting slide (14) connected to string (4). On the upper side of support (2) a centrally running longitudinal groove (11, 26) is provided in which drawing device (19, 22) can be inserted in its rest position.

Claims

1. A crossbow comprising a support (2) having a shoulder stock (1) at one end thereof and another end defining a front end, a bow (3) mounted on said support (2) and having a bow string (4), a shooting slide (14) slideably mounted on said support (2) and attached to said bow string (4), a trigger mechanism in said support adjacent said shoulder stock end and having means (8) engageable with said shooting slide for retaining said shooting slide in a cocked position, means (15) on said support adjacent said trigger mechanism for defining an arrow guide, a draw lever (19) having a first end pivotably mounted on said support to pivot about a horizontal axis (20) transverse to the longitudinal axis of said support and a second end disposed at said front end of said support in a rest position, a pusher member (22) having a first end pivotably connected to said draw lever and having a second end extending away from said front end of said support and engageable with said shooting slide, said support having means therein below a path of an arrow from said arrow guide for receiving said draw lever and pusher member whereby said draw lever and pusher member are recessed within said support below said path of an arrow when in the rest position.

2. Crossbow according to claim 1, wherein the draw lever end, resting on support (2), is designed in the shape of a fork.

3. Crossbow according to claim 1 wherein said receiving means comprises a longitudinal groove (11, 26), in said support running approximately centrally, at least partially receiving said draw lever (19).

4. Crossbow according to claim 3 wherein pusher member (22) is provided with an extension projecting beyond pivoting axis (23), said extension which, with draw lever (19) inserted, engages a stop (29) in said longitudinal groove (11, 26) to limit pivoting movement of pusher member (22).

5. Crossbow according to claim 4, and further comprising a resilient support element (30) in said longitudinal groove (11, 26) in the shooting direction behind pivoting axis (23) of pusher member (22), to raise said pusher with the second end from the stop, when draw lever (19) is released, to the level of shooting slide (14).

6. Crossbow according to claim 1, wherein the end of pusher member (22) opposite end (41) acting on shooting slide (14) is pivoted in a recess (21) on draw lever (19) extending lengthwise from its swivel support side end so that, with drawing device (19, 22) inserted, draw lever (19) and pusher member (22) are placed at least approximately parallel to the arrow shooting path.

7. Crossbow according to claim 1 wherein the distance between pivoting axis (23) of pusher member (22) on draw lever (19) and swivel axis (20) of draw lever (19) is at least half of the distance of shooting slide (14), connected to string (4), from trigger device (8).

8. Crossbow according to claim 1 wherein the front end of support (2) comprises a locking device (28) acting on recessed draw lever (19).

9. Crossbow according to claim 1 and means on said support for defining the movement path of the shooting slide (14).

10. Crossbow according to claim 9, wherein the movement path of shooting slide (14) is disposed under arrow guide (15).

11. Crossbow according to claim 1 wherein said second end (24) of pusher member (22) and front end (25) of shooting slide (14) are shaped complementary to one another.

12. Crossbow according to claim 1 wherein the draw lever is formed from at least two lever arms (41, 44) connected by a link, in which first lever arm (41), exhibiting the free end of the draw lever, and second lever arm (44) resting on swivel axis (20) of the draw lever are bent before their common axis (43) for connecting to support (2).

13. Crossbow according to claim 12, wherein pusher member (22) is connected to first lever arm (41).

14. Crossbow according to claim 1 wherein support (2) has a nonmetallic shaft.

15. Crossbow according to claim 1 wherein stock (1) and support (2) are constructed as one piece.
