DESCRIPTION:
BRIEF SUMMARY
The present invention relates to an optical cartridge adapted to be used in a regular, not-modified weapon to emit a light beam instead of a real projectile. In particular the invention relates to an autonomous optical cartridge for emission of a light signal when the weapon is fired, which cartridge includes at least one battery; a light source adapted to be energized by said battery(ies) so that a visible or an invisible light beam will be emitted; a firing switch adapted to be operated by a trigger acting on the weapon; and control circuits which represent a required interface between the battery(ies) and the light source.
Optical cartridges of the type described above is earlier known e.g. from U.S. Pat. No. 3,471,945 (G. K. Fleury) and a similar solution is also shown in German patent publication DE No.: 34 19 985 A1.
From these publications optical cartridges adapted to be placed in an ordinary weapon and also adapted to emit a light beam when the weapon is triggered, is earlier known. These patents in particular relate to cartridges in which the light beam is delayed a certain period of time to compensate the differences in travelling time between the rather slow projectile and the quite immediately acting light beam. The cartridge according to the be application is also developed to be used together with an optical shooting simulator.
However, all earlier known optical cartridges emit a light beam only when the trigger is operated. Therefore the earlier known light emitting cartridges are not able to show the aiming point movements before and after the shooting moment. The known light emitting cartridges are only active during the shot itself. If a simulator shall give valuable information to the shooter about how to behave to obtain better shooting results in a real shooting situation, the new features of the present invention are of great importance.
Thus the main object of the present invention is to provide a new, optical cartridge for shooting simulators, which cartridge emits an alignment signal or alignment beam at least during parts of the aiming process, so that the shooter also may obtain detailed information of the aiming process, not only the shooting process. In a preferred embodiment the cartridge also exits a specific firing signal when a shot is released, and this firing signal may comprise the alignment signal having an additional signal superimposed thereon, or the firing signal may correspond closely to the alignment signal, but may have e.g. a different frequency. More generally any signal parameter may be changed as long as the firing signal is distinguishable from the alignment signal.
These objects are met by using an optical cartridge designed according to the principles stated in the claims below.
The cartridge according to the present invention in addition to the earlier known elements includes: is loaded with said cartridge, to emit an alignment light signal, and light source at the firing moment and intitiated by the operation of the trigger, so that a firing light signal having a different and distinguishable mode is emitted.
To obtain this the cartridge 1 is connected to the control circuit in such a manner that said circuit 6 first will be energized as the loading switch SW1 is closed to emit a first alignment signal L1, then at the firing moment T.sub.0 initiated by the operation of the firing switch SW2, the cartridge 1 will emit a changed and detectable firing signal L2, and after a predetermined shot duration, only the alignment signal L1 will again be emitted until the loading switch SW1 is opened as the weapon is unloaded.
By constructing the optical cartridge in such a manner that it will emit a light beam of specific characteristics as soon as the cartridge is properly loaded into the weapon, it is obtained a new and valuable component for shooting simulators as this feature allows detection of the aiming point of the weapons barrel as well before as after the shooting.
