Abstract
A weapons simulator in which the rifle barrel is modified as a cylinder provided with a piston designed for movement therein, to provide a recoil effect. The rifle barrel itself serves as the cylinder and the piston is arranged for sliding motion therein, to provide the recoil effect, while actuating a rifle bolt mechanism. An end of the piston is provided with O-rings to seal it against the inside walls of the barrel. A portion of the barrel inside walls is conically shaped, defining a gap which the O-rings do not seal. Travel of the piston end through this barrel portion enables rapid compressed air exhaustion via the gap, simulating recoil. The conically-shaped barrel portion also guides piston re-entry into the cylinder, during a retraction motion of the rifle bolt mechanism.
Claims24
A recoil simulator for a weapon comprising:
- a rifle barrel having a sealing plug disposed therein proximate an exit end thereof, said barrel being formed with an inlet opening behind said plug for entry of compressed air therein;
- and
- a piston rod and cylinder arranged for sliding motion one with respect to the other, a gap being developed therebetween during a portion of said sliding motion, said cylinder being in fluid communication with said barrel inlet opening, said sliding motion being arranged to actuate a rifle bolt firing mechanism,
- such that when said compressed air is directed to flow within said rifle barrel, said piston and cylinder sliding motion simulates a rifle bolt firing action, and rapid release of said compressed air via said piston and cylinder gap simulates recoil.
A method of operating a recoil simulator for a weapon comprising the steps of:
- providing a rifle barrel having a sealing plug disposed therein proximate an exit end thereof, said barrel being formed with an inlet opening behind said plug for entry of compressed air therein;
- providing a piston rod and cylinder arranged for sliding motion one with respect to the other, a gap being developed therebetween during a portion of said sliding motion, said cylinder being in fluid communication with said barrel inlet opening, said sliding motion being arranged to actuate a rifle bolt firing mechanism;
- and
- directing compressed air to flow within said rifle barrel, such that said piston and cylinder sliding motion simulates a rifle bolt firing action, and rapid release of said compressed air via said piston and cylinder gap simulates recoil.
