  • Patent number: 6397507
    Abstract: An apparatus for a firearm, the firearm having a user hand-gripable barrel portion. The apparatus has a U-shaped member with an outwardly extending cylindrical protuberance swivelably disposed thereto. An elongated handle is detachably secured to the cylindrical protuberance. An elevated contoured member is mountably disposed along the curved portion of the U-shaped member. The elevated contoured member is formed to receive a selected portion of the hand-gripable barrel of the firearm. An elongated strap is connectively disposed to the U-shaped member. The elongated strap traverses the hand-gripable barrel portion of the firearm thereby detachably securing the firearm to the U-shaped member.

  • Publication number: 20020002788
    Abstract: The present optical imaging device comprises an electro-optical recording device, such as a digital still camera, videotape recorder, etc, physically and optically connected to the scope sight of a firearm. The scope may be provided with a half silvered mirror at the eyepiece, which reflects a portion of the image passing through the scope to the axially offset recording device. The user of the firearm and optical system may thus continue to view the image through the scope. Other embodiments provide a small, light weight micro camera fitted to the scope eyepiece, with the camera receiving the image from the eyepiece and providing that image to the user through a rearward viewing screen. A switch may be provided to operate the system upon trigger actuation, or independently of the firearm trigger. The system is particularly valuable in sighting in a weapon or harmlessly capturing an image of an animal.

  • Patent number: 5909002
    Abstract: A buffer assembly for use with firearms such as the M-16 rifle, for reducing the cyclic rate of firing in full-automatic operation. The buffer assembly includes a unit of length selected to stop the bolt carrier at the desired full-recoil position, and a mass movable relative to that unit. When the bolt carrier stops at full-recoil, inertia causes the mass to continue moving rearwardly while further compressing the action spring. The action spring then returns that mass forwardly to contact the fixed portion of the buffer assembly, returning the bolt carrier to battery position. The bolt carrier remains at rest in recoil while the moveable weight slides rearwardly and then returns forwardly relative to the bolt carrier, thereby increasing the cycle time of firing and correspondingly reducing the cyclic rate of fire for the firearm.

    Abstract: The gun storage and rapid removal mount of this invention is for securely retaining a shotgun or the like against unauthorized removal with the mount providing for rapid removal by authorized persons. It comprises a trigger guard cup and a forward lock clamp. The lock clamp engages the barrel and a magazine tube just forward of the shotgun receiver to prevent forward motion of the shotgun in the mount. The trigger guard cup prevents rearward motion. The lock clamp is both lock- and spring-retained. When its lock is released, the gun can be rotated out of the clamp against spring force. The spring also permits reinsertion of the shotgun into position against the spring force.

  • Patent number: 5377438
    Abstract: A device for preventing the accidental discharge of a bullet from a firearm, including an attachment adapted to engage the muzzle end of a firearm barrel, a tubular body coaxially attachable with one of its ends to the barrel via the attachment, the bore of the tubular body is provided with an abutment, a stopper fixedly attachable to the other end of the body and having a central bore of a diameter exceeding the calibre of the firearm, an impact disk slidably disposed in the bore of the tubular body, and energy-absorbing and storing element interposed in the bore between the impact disk and the stopper. Upon the discharge of a bullet, the latter pierces the impact disk while transferring some of its kinetic energy to the energy-absorbing and storing element, causing the bullet to disintegrate into small particles escaping through the bore in the stopper.

  • Patent number: 5343649
    Abstract: A specialized recoil absorber mounted to a gun dampens and absorbs the recoil force of a gun during the firing thereof. The recoil absorber includes a closed, fluid filled cylinder having a first end and a second end. A piston closely fits within the cylinder and slides therein along the cylinders longitudinal axis and a spring is compressed between the piston and the first end. The cylinder defines channels at an outer diametrical surface thereof, the channels having a helical twist centered on the longitudinal axis, whereby the piston rotates as it translates.

  • Patent number: 5339789
    Abstract: A low-recoil gun (10), in particular a compressed-air gun or hand firearm, is proposed, comprising a stock assembly (25) and a barrel assembly (20) displaceable relative to the stock assembly (25) in the longitudinal direction (B) of the gun (10). The barrel assembly (20) can be moved contrary to the direction of fire (A), on the occasion of a discharge, out of a position of readiness to fire. The reverse travel of the barrel assembly (20) due to the discharge is restrained by an locking device (40) capable of being overcome by the recoil energy of the barrel assembly (20). In overcoming the locking device, the barrel assembly (20) performs work, which is deducted from the recoil energy, so that the recoil ultimately transmitted to the gunner is at least substantially reduced. In the gun according to the invention, the axial force required in longitudinal direction (B) of the barrel to overcome the locking device (40) is adjustable.

  • Patent number: 5309660
    Abstract: A cartridge magazine for firearms comprises a key insertable through a slot in the end panel of the magazine for engaging the spring engaged elevator upon which the shells are supported. The slot includes a series of transverse or lateral branches spaced longitudinally on the panel for receiving the key and locking the elevator in position. The magazine thus may be loaded with cartridge shells in stages as defined by the lateral locking branches. After loading is completed, the key may be removed from the magazine and clip so that the latter may be inserted into the firearm with which it is used. In an alternatively preferred embodiment, optional marking means are positioned on top of the magazine for placing an identifying marking on each cartridge shell.

  • Patent number: 5305678
    Abstract: A compensated barrel shroud that encloses and supports a firearm barrel provides a first portion of the shroud for receiving the barrel that extends from the firearm frame to an end of the barrel. There is a second larger inner diameter portion extending from the end of the barrel to a forwardmost outer end of the shroud. The barrel and shroud are screwed together by interengaging threads positioned adjacent the end of the barrel. The end of the shroud has a decreased diameter exit hole defining an expansion chamber within the second larger inner diameter portion. At least one slot is formed along a top surface of the second portion to allow expanding propellant gas from within the second portion to escape. The slot is sized and arranged to provide a downward thrust to the barrel shroud to compensate recoil forces generated in firing a round.

  • Patent number: 5307053
    Abstract: A hunter alert device (9) for use by hunters when hunting wild game consists of transmitter means (21), receiver means (22), an antenna (11), a transceiver controller (20), and an indicator means (12). The device (9) operates by intermittently transmitting a modulated radio frequency signal through antenna (11) and listening for radio frequency signals transmitting from alert devices worn by other hunters. When a signal is detected, the receiver means (22) determines whether the signal is within a predetermined range of the hunter and, if so, activates the indicator means (12) to warn the hunter.
