Shock-absorption device of piston mechanism in simulation gun
A simulation gun in which an air current is ejected by an operation of a piston mechanism portion to fire a bullet, a piston stop which is movable relative to a piston mechanism portion is provided, the piston stop is attached to one constituent member of the piston mechanism portion to absorb an impact force accompanying the operation of the piston mechanism portion, and shock-absorption means is provided between the piston stop and the other constituent member of the piston mechanism portion.
1. A shock-absorption device of a piston mechanism in a simulation gun in which an air current is ejected by an operation of a piston mechanism portion to fire a bullet,
wherein a piston stop which is movable relative to the piston mechanism portion is provided,
wherein the piston stop is attached to one constituent member of the piston mechanism portion to absorb an impact force accompanying the operation of the piston mechanism portion, and
wherein shock-absorption means is provided between the piston stop and the other constituent member of the piston mechanism portion,
wherein the simulation gun is a gas gun which ejects gas to the bullet by the piston mechanism portion and moves a piston mechanism and a bolt backward by a differential pressure valve mechanism built in the piston mechanism, and
wherein a mass of the piston mechanism portion which moves backward is weighed to a mass of the bolt as the impact force.
