Abstract

A crossbow with a vibration-damping device has a stock assembly, a bow assembly, a bushing and at least one resilient element. The stock assembly has a front end. The bow assembly is attached to the front end of the stock assembly. The bushing is clamped between the stock assembly and the bow assembly. The at least one resilient element serves as a vibration-damping device and is clamped between the bushing and the bow assembly. By adding the resilient element, vibrations of the bow assembly are greatly reduced, and the bushing can be selectively made of rigid material to keep the structure of the crossbow sturdy.

Claims

1. A crossbow with a vibration-damping device, the crossbow comprising:

a stock assembly (10) having a front end;

a bow assembly (20) attached to the front end of the stock assembly (10);

a bushing (30) clamped between the stock assembly (10) and the bow assembly (20); and

at least one resilient element (40) serving as a vibration-damping device and clamped between the bushing (30) and the bow assembly (20).

2. The crossbow as claimed in claim 1, wherein

the bow assembly (20) has:

a mating block (24) having

two sides;

a rear face;

a bushing recess (242) defined in the rear face; and

two cavities (244) defined in the rear face within the bushing recess (242);

a bow (22) composed of two resilient arms, each resilient arm having a proximal end attached to and extending out from one of the two sides of the mating block (24);

a bowstring (26) connected between the two distal ends of the resilient arms; and

two resilient elements (40) mounted respectively inside the two cavities (244) inside the mating block (24).

3. The crossbow as claimed in claim 2, wherein the bushing (30) is mounted inside the bushing recess (242) and is H-shaped.
