The specification of this application describes a target practice system which includes an optical arrangement by which light may be directed from a gun towards a target. The target includes a photosensitive means connected to initiate a scoring display system. The source of light for the gun is located at a point remote from the gun and light from the source is conveyed to the gun through a fiber optical conducting system. The source generates flashes of light in a gas tube which is fired by an electrical signal as an incident to alteration in light flux in an optical subsystem. The subsystem includes a second light source and fiber optic circuitry for conducting light from the second source through the gun and thence to light-sensitive circuitry in which the initiating pulse is generated. Means are provided within the gun for altering the light flow through the gun in response to actuation of the trigger mechanism. In the embodiment described in detail in this specification, the initiating pulse is generated by the secondary optical system upon the occasion of interruption of light flow through the secondary fiber optical circuit.
A multiple laser beam system comprises a laser device which is intended to be attached on or near the barrel of a rifle or the like such that triggering of the weapon activates the laser transmitter and results in the laser device producing a plurality of beams which by means of an adjustable diverging lens on the laser device may be defocused to produce an overlapping pattern. The beams are transmitted sequentially by the laser head assembly while timing of the transmission of the beams is controlled by electronic beam encoding logic. When the weapon is fired a mechanical-to-electrical transducer is energized and generates an electrical signal used to trigger the laser firing sequence. Visual indication means are provided to indicate that the laser timing sequence has been initiated. The light beam is detected by a target having a plurality of light sensing detectors. Whereby an indication of the accuracy of the aim of the weapon may be obtained.
An amusement device including an enclosed housing having viewing windows at each end, a simulated lunar surface extending longitudinally between the ends of the housing and operator-controlled movable objects in the shape of extraterrestrial vehicles for directing and responding to laser beams such that a laser beam duel may be simulated. A dramatic effect is introduced by causing the laser beam to sweep outwardly across the lunar surface to simulate the firing of the laser gun.
A laser sight for a firearm (10) having a recoil spring guide (15) mounts components on the spring guide so that a light beam (18) is directed along the axis of the spring guide. This automatically makes light beam (18) parallel with the barrel (11) of firearm (10). Several mounting alternatives are possible, including a collimating lens (21) arranged on the axis of the spring guide to receive light from a laser diode (20) that is either mounted on the spring guide with the collimating lens or mounted remotely and arranged for directing light to collimating lens (21) via a fiber optic cable (25). These arrangements can also conceal the laser light within the firearm, where it is well protected and not noticeable.
A safety indicator for guns, and particularly shot guns and rifles, utilizing a movable slide member which sets or releases the safety mechanism of the gun. A pair of jewels, in the form of glass or plastic crystals, are mounted in the gun stock to be selectively covered and uncovered when the slide member is moved to one or the other of its two positions, one jewel preferably being red and exposed when the slide member is moved to unlock the trigger. The invention utilizes fiber optic rods to transmit light from an electric bulb which is energized when the safety slide member is moved to trigger unlocking position. Fiber optic rods are also utilized to transmit daylight to both of the jewels.
The invention provides a light sensitive dummy cartridge for insertion into he chamber of a magazine-type weapon. A muzzle collimator is inserted into the barrel in alignment with the cartridge photosensor and the longitudinal axis of the bore. The power supply, audible scoring apparatus, and electrical circuit for the photosensor, moreover, are mounted in a dummy magazine. This combination provides an easy-to-install apparatus for temporarily converting a conventional firearm into a photoresponsive training device.
