  • Patent number: 6938534
    Abstract: A bolt locking assembly for a weapon simulator, the weapon simulator having a bolt affixed to a firearm housing providing recoil to the user. The bolt is connected to a piston housed in a piston chamber inside the housing. A gas supply provides a compressed gas or fluid into the piston chamber to generate movement and recoil of the piston. After the weapon simulator has been fired a predetermined number of times, the bolt locking assembly will obstruct operation of the bolt and piston. The bolt locking assembly includes a lock actuator port engaging the piston chamber, a locking apparatus positioned within the housing proximate the bolt, and a lock channel between said lock actuator port and said locking arm, wherein the lock channel directs gas to said locking apparatus to actuate said locking apparatus and fix the bolt in place.

  • Patent number: 5947738
    Abstract: A simulated weapon includes a pressure switch within the simulated weapon's barrel. The pressure switch responds to pressure changes within the weapon barrel to activate a light emitter. In response, the light emitter emits a beam of light that simulates weapon fire by indicating the aim of the simulated weapon. Pressure changes within the barrel are induced by a conventional air cartridge that emits a blast of air when struck by the firing pin of the simulated weapon. The user can thus produce the simulated fire by activating the simulated weapon's trigger to trip the hammer and drive the firing pin into the air cartridge. In another embodiment, the simulated weapon activates a nonlethal pyrotechnic round. Simulated fire is produced in response to detection of the recoil, force, or pressure change produced by the pyrotechnic round. The simulated weapon may be a pistol, rifle or any other conventional hand held weapon.

  • Patent number: 5857854
    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.

  • Patent number: 5823511
    Abstract: A system for exerting a force, for instance a vertical upward lifting force of a predetermined tension vs. time waveform on a suspended object is useful in training the operators of shoulder-supported rocket launchers. The system includes an actuator for generating a required tensile force, a non-stretchable line or cable for connecting the object to the actuator and an overhead guide supported on an overhead support structure. The cable passes over the guide means defining a portion of the cable directly supporting the object. The position of the guide is controlled, in a response to a deviation from verticality of the portion of the cable with suspended object, before the activation of the actuator so that the verticality of the object lifting force is maintained. In operation, a predetermined force is exerted on the object regardless of whether the object moves as a result of the force.

  • Patent number: 5569085
    Abstract: A gun game machine wherein the player can hold a model gun in the hand away from an machine casing. This gun game machine comprises a bullet hitting optical detection unit installed in the model gun for detecting a simulated bullet hitting position, a sliding cover provided on an exposed outward portion of the gunbarrel of the model gun and slidable in the longitudinal direction of the gunbarrel section, and a cover driving means for instantaneously moving the sliding cover at high speed. The model gun and the game machine casing may be coupled to each other by means of a flexible cable containing electric conductors. The sliding cover makes a long reciprocating motion similar to the so-called blow-back movement of an actual gun, so that the player can feel a similar reaction or impact corresponding to the firing of the actual gun. This simulated firing operation also serves to attract spectators to the game.

  • Patent number: 5257937
    Abstract: For training persons having to fire missiles from the shoulder, a simulator is proposed which comprises a simulated launch or firing tube (10), which carries a front, releasable or jettisonable mass (12) and a rear releasable or jettisonable mass (14) at its ends. These masses are held by electromagnets (34, 36). When the person firing or firer presses the trigger (18), the rear mass (14) is ejected to the left followed, with a time lag (.DELTA.t), by the front mass (12). Thus, the load relief and site and bearing movements felt by the firer during a real launch are restored.

  • Patent number: 5201658
    Abstract: An artillery simulator apparatus is provided including a gun tube which is swingably mounted to a rotatable cab. During simulator recoil and counter-recoil, the gun tube is held in fixed position while the breech moves under computer control from an "in battery" position to a recoil position and then back to the "in battery" position. Breech recoil speed and stroke are controlled to simulate actual M109 breech performance based on propelling charge, type round, and gun tube elevations. A double acting hydraulic cylinder is attached to the breech to drive the breech in the recoil and counter-recoil directions. During recoil and counter-recoil, the hydraulic cylinder is positively driven by fluid from the same hydraulic source. The simulator includes sensors for determining the type of round placed in the breech, the round fuse type and run time setting, the firing primer, as well as the level of propelling charges in the breech.

  • Patent number: 4829877
    Abstract: An accessory for converting a small bore firearm into a safe theatrical stage prop providing both aural effects of the "report" of detonated gunpowder and visual effects of discharged "gunsmoke" and "recoil" motion imparted to the body of a user, is constructed with a central passage 20 partially obstructed by a dimensionally conforming cylindrical mass 36. Effluent in the form of expanding gases of detonated gunpowder enter central passage 20 via proximal orifice 16, impart forward motion in a preferred direction to cylindrical mass 36 and, as movement of mass 36 exposes connecting passages 30, the effluent bypasses the central portion of passage 20 via passages 22 and exits the barrel 10 of the accessory via distal orifice 18. Motion imparted to mass 36 first by the expanding effluent and then in a reverse direction by compressed spring 40, simulates the visual effect of "recoil" upon detonation of a blank cartridge of ammunition.
