Abstract

A crossbow that enables arrows to be shot with simple operation is provided. The crossbow includes a bow stock that has a fitting recess for a cylinder formed between a front end and a rear end thereof, a bow that is attached to the front end of the bow stock thereacross, and has a string tensioned between both ends thereof, a wire catch that is rockably provided at the rear end of the bow stock to hook the tensioned string, a trigger that is provided at the rear end of the bow stock to cock the wire catch that has hooked the string and to release the cocking of the wire catch by triggering, thereby shooting an arrow, a cylinder that is rotatably fitted in the fitting recess of the bow stock, and has a plurality of arrow grooves formed at predetermined angular intervals in an outer peripheral surface thereof so as to extend in a longitudinal direction, and has arrows slidably inserted in the plurality of arrow grooves, respectively, and a rotation operating mechanism that rotates the cylinder at every predetermined angle, and locates one arrow groove in front of the wire catch.

Claims

1. A crossbow that shoots arrows by triggering, comprising:

a bow stock that has a fitting recess for a cylinder formed between a front end and a rear end thereof;

a bow that is attached to the front end of the bow stock thereacross, and has a string tensioned between both ends thereof;

a wire catch that is rockably provided at the rear end of the bow stock to hook the tensioned string;

a trigger that is provided at the rear end of the bow stock to cock the wire catch that has hooked the string and to release the cocking of the wire catch by triggering, thereby shooting an arrow;

a cylinder that is rotatably fitted in the fitting recess of the bow stock, and has a plurality of arrow grooves formed at predetermined angular intervals in an outer peripheral surface thereof so as to extend in a longitudinal direction, and has arrows slidably inserted in the plurality of arrow grooves, respectively;

a rotation operating mechanism that rotates the cylinder at every predetermined angle, and locates one arrow groove in front of the wire catch;

a cocking device composed of pallets that hook the string of the bow on the wire catch; and

an operating mechanism that makes the pallets slide rearward along the bow stock;

wherein the rotation operating mechanism is operated by the operating mechanism of the cocking device so as to rotate the cylinder by a predetermined angle;

the rotation operating mechanism has an operating lever that is rockably provided on a side surface of the rear end of the bow stock, the operating lever has a front end fitted in one arrow groove of the cylinder, and is kicked by the operating mechanism of the cocking device to rotate the cylinder by a predetermined angle, and the operating lever is separated from the arrow groove in which its front end has fit, and fits in the next adjacent arrow groove.

2. The crossbow according to claim 1,

wherein the rotation operating mechanism is operated by the operating mechanism of the cocking device so as to rotate the cylinder by a predetermined angle.

3. The crossbow according claim 2,

wherein the rotation operating mechanism has an operating lever that is rockably provided on a side surface of the rear end of the bow stock, the operating lever has a front end fitted in one arrow groove of the cylinder, and is kicked by the operating mechanism of the cocking device to rotate the cylinder by a predetermined angle, and the operating lever is separated from the arrow groove in which its front end has fit, and fits in the next adjacent arrow groove.
