Laser aiming system for weapons
First Claim
1. An aiming system for attachment to a weapon having an elongate barrel which comprises:
- a laser for projecting a beam of coherent light onto a target to indicate the impact point of a projectile fired from the weapon; and
apparatus mounting said laser on said weapon in a manner such that the laser is free for limited longitudinal movement relative to the weapon generally parallel to said barrel,said apparatus including a pneumatic buffer device for cushioning said laser from shock upon recoil of the weapon, which comprisesa cylinder held in fixed relation to the aiming device, anda piston disposed within said cylinder for longitudinal movement therein, said piston being operably connected to said weapon and having a valve mechanism operable in response to fluid pressure within the cylinder.

Abstract
A laser aiming system for attachment to a conventional firearm such as a pistol, rifle or shotgun is disclosed, which system utilizes a laser to project a beam of a coherent light onto a target at a given range to indicate the impact point of a projectile fired from a weapon. The laser aiming system includes a laser tube, a self-contained power supply module and apparatus for mounting the laser to the weapon whereby the recoil force developed during firing of the weapon will not be injurious to the laser. The mounting apparatus includes a track fixed relative to the firearm with a carriage that is slidable thereon to provide limited longitudinal reciprocating movement of the laser relative to the weapon. A pneumatic device is operably disposed between the carriage and the weapon to absorb and dissipate the energy of recoil. Compression springs are provided and disposed on opposite sides of the carriage to yieldably resist longitudinal movement of the carriage and return it to an intermediate position on the track after recoil. An attachment mechanism releasably secures the mounting apparatus to the weapon.

5. An apparatus for mounting an aiming device to a weapon having an elongate barrel, comprising:
-
a mechanism for providing the aiming device with longitudinal movement relative to the weapon; attachment means adapted to secure said mechanism to the weapon; and a pneumatic buffer device operatively connected to said mechanism for absorbing recoil energy to cushion the aiming device from shock upon recoil, said pneumatic device comprising a piston cylinder held in fixed relation to the aiming device, a piston disposed within said cylinder, having a valve mechanism operable in response to fluid pressure within said cylinder to release fluid contained therein, and a rod extending through said cylinder with said piston secured thereon, said rod being held in fixed relation to the weapon. - View Dependent Claims (6, 7, 8, 9)

10. An apparatus for mounting a laser being used as an aiming device to a weapon having an elongate barrel, comprising:
-
an elongate guide having attachment means formed thereon to secure said guide in fixed position relative to the weapon and substantially parallel to the elongate barrel of the weapon; a carrier adapted to embrace said elongate guide for longitudinal reciprocating movement relative to said guide; holding means having clamps for embracing the aiming device, said holding means being attached to said carrier for pivotal movement in the vertical and horizontal planes of the weapon relative to the barrel of the weapon; windage and elevation adjustment mechanism connected between said holding means and said carrier for positioning said holding means relative to the weapon to sight in the aiming device at the desired target range; a pair of compression springs disposed about said guide at opposite ends of said carrier to yieldably resist movement of said carrier relative to said guide and urge said carrier to intermediate position between opposite ends of said guide; and a pneumatic buffer device arranged to absorb recoil energy and cushion the aiming device from shock, said pneumatic buffer device comprising a piston cylinder connected to said carrier; a rod extending through said cylinder affixed to the elongate guide by a clamp; a piston disposed in said cylinder and secured on said rod, said piston having fluid release ducts formed therein; an end cap movable along said rod and urged into abutment with said piston by a spring to seal off the fluid release ducts, said end cap serving as a valve mechanism to release fluid from said cylinder through the air release ducts in said piston in response to fluid pressure build-up within said cylinder.
