  • Publication number: 20120218741
    Abstract: The present invention is a mounting apparatus for forward illumination devices on firearms, particularly long guns. The invention is mounted on the forward sight mount of a firearm and positions a mounting rail below said sight but above the barrel of the firearm, thereby positioning a light source, or any other device, unobtrusively along the line of sight of the user. Various devices may be mounted in this manner, including pointing devices and illumination devices. In order to provide greater control of the device to the user, power and control switches may be mounted behind the mounting device and closer to the stock, hand guard or grip of the weapon.

  • Publication number: 20080222935
    Abstract: The present invention is an improved multiple piece grip safety for handguns. The safety comprises a fixed main body and two interfacing pivoting members, pivoting about the top and bottom of the grip respectively. The two interfacing pivoting members counteract each other to prevent accidental disengagement of the safety while also providing a more efficient purposeful disengagement.

  • Patent number: 6860053
    Abstract: The present invention discloses a grip fractioning pattern for any object, but specifically designed for handgun and rifle grips. The pattern consists of a series of spaces frusto-conical projections regularly spaced about the surface of the weapon's grip. Alternatively, the series may be interrupted by an interspaced series of pyramids, with their points not extending above the height of the frusto-conical projections. The grip pattern may be utilized in any circumstance where a user desires greater and more comfortable friction when gripping an object.

  • Patent number: 6785994
    Abstract: The invention is a firearm safety indicator that is spring-loaded, thus enabling self-ejection when a firearm's bolt is actuated. To attain this, the indicator comprises a main body and cantilever spring body joined together. A peg extends perpendicularly from the main body. In use, the peg is positioned inside the firing chamber of a firearm through the ejection port. The main body covers the ejection port and the cantilever spring body is therefore compressed to attain proper positioning. The rifle's bolt is then used to engage and hold the peg in place. When actuated, the bolt releases the peg and the spring body is released, thrusting the indicator away from the firearm. Alternately, a metal spring may be utilized in the place of the cantilever spring body.

  • Patent number: 6418656
    Abstract: Gunstock storage assemblies for scope adjustment covers and shotgun chokes are provided. The assemblies utilize the threaded nature of such covers and chokes to provide a secure and convenient storage of the items. For adjustment covers, a cup or shaft is embedded in a gunstock. A washer and retaining mount are inserted towards the inner end of the cup or shaft and are held in place by a screw passing through the mount, washer, and cup and into the gunstock. The mount is male threaded to receive an adjustment cover. For chokes, a female threaded shaft is similarly embedded and is sized to receive a choke. Both cup and shaft may be secured with an adhesive such as epoxy.

  • Patent number: 5816683
    Abstract: A flashlight adapter for a handgun having a base retainer receivable into the interior of a magazine through a distal end thereof. A spring biases the base retainer toward the distal end. The magazine has a flange about the distal end of the magazine. A magazine base is removably engaged on the flange and is secured in its assembled position by protuberances extending from the base retainer being received in apertures in the magazine base. The magazine base has a channel therein for receiving a lightholder for holding a flashlight therein. The lightholder is selectively received within the magazine base.

  • Patent number: 5104185
    Abstract: An armrest assembly (10) disposed for use with a vehicle seat assembly (12) includes a lower bin (18) defining a storage compartment (20) and an upper cover (22) pivotal about the bin (18) by a hinge (24) between a closed position covering the lower bin (18) and an open position opening the storage compartment (20). The armrest (10) includes a container support (40) hingedly connected by support hinge (42) to the armrest (10) and pivotal between a stored position in the compartment (20) and an extended operational position outside the armrest (10). The container support (40) includes a pair of arms (120, 120') defining a pair of opening (132, 132') for receiving at least one beverage container. The arms (120, 120') are independently pivotal (126) to receive different sized containers in each of the openings (132, 132'). The openings (132, 132') further include a pair of slots (142, 142' ) for receiving a handle of the container.
