Abstract

There is provided a recoil shock device capable of obtaining the same recoil shock as that in a case where the weight of a piston is increased, without increasing the weight of the piston by separately providing a movable part and a weight of a piston/cylinder. There is also provided a recoil shock device capable of obtaining a recoil shock similar to that in a real gun, without damaging the outer appearance of a gun. In order to drive a weight to obtain imitated recoil, i.e., a recoil shock by operation of a movable part in a piston/cylinder which generates compressed air, a communicating part 31 which is moved in its retreating direction by the movable part 13 is provided, and a recoil spring 35 which receives a force transmitted to the weight 33 via the communicating part 31 by the movable part 13 so as to be in a compressed state is provided. A reaction that accompanies movement of the weight 33 when the recoil spring 35 is compressed and the recoil spring 35 is then extended by its resilient force is transmitted to a main body 37 of the gun.

Claims4

Dependent claims

A recoil shock device in a toy gun, the recoil shock device comprising:

a piston/cylinder unit having a piston spring, a movable part and a fixed part,
a communicating part moving in a retreating direction by movement of the movable part,
the piston spring being compressed by the movement of the movable part in the retreating direction,
a weight, and
a recoil spring receiving a force transmitted to the weight via the communicating part by the movement of the movable part in the retreating direction so that the recoil spring is moved into a compressed state, the recoil spring spacing the weight from engagement with a main body of the gun,
the weight being movable after the recoil spring and the piston spring are compressed and thereafter during release of the compression of the piston spring, the recoil spring being released and extended by a resilient force of the recoil spring, and
a reaction force being transmitted by the weight to the main body of the gun simultaneously with extension of the recoil spring to imitate recoil of the main body of the gun and by the piston spring to create or amplify recoil shock.
