Definitions
- the present invention relates to a laser pointer for handgun or long gun, which is compact and modular in design.
- Known laser pointers are in the form of a housing intended to be mounted above the sight of the weapon, under or next to the barrel, with control by cable and microswitches.
- the laser beam is adjusted using two screws projecting from the housing.
- the axis of the laser beam has a parallax which is not negligible relative to the firing axis and the handling of the weapon on which the pointer is mounted requires the use of both hands, it that is to say a hand for controlling the laser and a hand for controlling the trigger of the weapon.
- the subject of the invention is a compact laser pointer whose mechanical design allows mounting on a weapon so that the parallax is greatly reduced.
- a laser pointer characterized in that the la ⁇ ser cell is housed in a laser holder nose mounted on a housing intended to receive a current source, this housing being carried by a support for mounting on a weapon, said support carrying a lever mounted to tilt around a pivot fixed on the support and extending parallel to the axis of the laser holder nose, said lever being arranged so that, when it is in the tilted position, it actuates a contactor which cooperates with a contact so that the cell is energized.
- the aforementioned lever preferably has a shape which presents an arm which is offset laterally relative to the vertical axial plane of the housing. This arrangement has the advantage of allowing the laser and the trigger to be controlled simultaneously and with one hand.
- a second aspect of the invention consists in that the direction of the axis of the laser beam is maintained and adjusted by rods arranged in two orthogonal direc ⁇ tions and clamped between the external surface of the laser cell and the rings having an inner surface off-centered with respect to the axis of the laser cell, the rotation of each of these rings causing the rods to move axially which press against the inner surface of the ring.
- FIG. 1 is an axial sectional view of a mode exemplary execution of the laser pointer according to the invention
- FIG. 2 is a cross-sectional view following line II-II of FIG. 1
- FIG. 3 is a cross-sectional view following line III-III of FIG. 1
- Figure 4 shows a variant of equiva ⁇ slow assembly of Figure 3.
- the laser pointer comprises a nose 1 in which is housed the laser cell 10 which contains the electronic and optical elements, known per se, necessary for the production of 'a laser beam.
- the nose 1 is mounted on a housing 2 which contains the battery or batteries constituting the current source.
- the housing 2 is closed by a cover 3, the opening of which allows the introduction of the current source.
- the laser cell 10 is held by a hardened steel ball joint 11.
- the direction of the axis L of the laser cell 10 that is to say the direction of the axis of the laser beam, is held by rods 12, 13 arranged in two orthogonal directions.
- the direction of the axis of the laser beam is adjusted by moving the rods 12 and 13 axially.
- these rods are tightened between the exterior surface of the laser cell 10 and the interior surface of two rings 14 and 15. As shown in particular in FIG. 3, the interior surfaces of the rings 14 and 15 are decent ⁇ relative to the axis L of the laser cell 10.
- the rods on which the ring rests are displaced axially and consequently move the axis L of the laser beam.
- the rods 12 and 13 can be replaced by balls 16 or springs 17, for example.
- FIG. 4 schematically illustrates these two variants at the same time. Adjustment by off-center rings has the advantage of eliminating the protruding adjustment screws and of reducing the size of the nose while ensuring perfect sealing.
- the housing 2 is carried by a support 4 allowing the mounting of the device on a weapon.
- a lever 5 which can pivot around a pivot axis 6 extending parallel to the axis of the pointer and visible in Figure 2.
- the lever 5 is arranged so that, when it is in tilted position, it actuates a contactor 7a which cooperates with the contact 7b to ensure the energization of the laser cell 10 in order to produce a laser beam.
- a lock 8 makes it possible to block the lever 5 in order to avoid unwanted allu ⁇ mages of the laser.
- the support 4 can be in one piece with the housing 2.
- the lever 5 has a curved shape having an arm which is offset laterally relative to the vertical axial plane of the housing 2. Thanks to this arrangement, the laser pointer according to the invention can be mounted on a weapon in an angular position located at 45 ° with respect to the vertical axial plane of the aiming device of the weapon, thus bringing the axis of the laser beam closer to the firing axis, which reduces parallax. In addition, the laser pointer then leaves the aiming device free.
- control lever 5 can be placed on the side of the barrel of the weapon and be actuated with one hand and at the same time as the trigger of the weapon.
- the lever 5 can also be placed indiffé ⁇ ment to the right or left of the barrel.
- the modular design of the laser pointer according to the invention allows a large number of variants of execution.
- the shape of the housing 1 can be adapted to the batteries provided and the support can be adapted to the weapon models while retaining advanced manufacturing standardization and ensuring great flexibility in mounting depending on the weapon model or according to the user's wishes.
