Definitions

• the present invention relates generally to a laser beam pointing device intended to be fixed to a firearm to facilitate pointing at a target. It relates in particular to an improved construction method and in particular an axial positioning device for the laser generator.
• a laser pointing or aiming device is in the form of an elongated housing in which are housed a laser generator, a source of electrical energy for supplying the laser generator and an axial positioning device for adjust the axial position of the laser generator inside the housing in order to orient the axis of the laser beam so that at a predetermined distance from the weapon on which the pointing device is fixed, the axis of the laser beam coincides with the axis of the gun barrel.
• a pointing or aiming device with a laser beam facilitates aiming, in particular when the shooter is operating in poor lighting conditions, the laser beam reproduces the slightest trembling of the weapon.
• an adjustment of the laser beam is only valid for a well-determined distance because the laser beam has a perfectly straight path while the projectile has a curved path. Adjusting the beam as a function of the distance from the target is therefore a particularly delicate problem which calls for very fine adjustment.
