  • Patent number: 8915009
    Abstract: Embodiments provide modular illumination systems that may be used with any handgun platform, and are not specific to any make or model. Some embodiments may provide lighting, for instance visible light and/or infrared light for use in low light or dark environments. Also provided in various embodiments are aiming and/or sighting systems that may be equipped with an IR sight or a laser sight, such as a red or green laser. In various embodiments, the illumination modules may couple to the handgun via a mounting member that is integral to the handgun body, and the mounting member may be recessed or otherwise concealed and/or protected by the handgun body. Thus, in various embodiments, no portion of the mounting member (or the corresponding mounting element on the illumination module) is exposed or visible when the illumination module is coupled to the mounting member, and a conventional holster may be used.

  • Patent number: 8256154
    Abstract: The present invention provides a sighting device for a firearm having a trigger guard, a frame with an underside portion forward of the trigger guard, and a handgrip with a front strap. The sighting device has a body having a first portion including an illumination device. The body defines an engagement feature operable term the bubbly connectivity for portion of the trigger guard. The body has an elongated extension portion that extends from the first portion. The extension portion is shaped to underlie a lower portion of the trigger guard from the first portion to the front strap. The extension portion has a free end including a switch, and the extension portion includes a conductor operably connecting the switch to the illumination device.

  • Patent number: 7805876
    Abstract: The present invention overcomes the limitations of the prior art by providing a sighting device for a firearm having a handgrip with a front strap, a back strap, and a free end. The sighting device has a body including a sleeve defining a bore sized to closely encircle at least a portion of the handgrip. The sleeve has a front portion configured to wrap about at least a forward front strap portion of the firearm, and has a rear portion configured to wrap about at least a rear back strap portion of the firearm. A laser device is connected to the body. The body may be an integral element, and may have a switch on the front span. The body may have a removable lock device that engages an upper rear protrusion of the frame, and the device may attach to the firearm without any fasteners engaging the firearm.

  • Publication number: 20090293855
    Abstract: An apparatus for improving an archer's aiming consistency by utilizing a directed light beam device mounted to an archery bow or integrated into the grip of an archery bow. Various embodiments provide an apparatus comprising a directed beam light source such as a laser, a power source for providing power to said light source, an actuation switch for allowing power to flow from said power source to said light source, a circuit for interconnecting said light source, said power source, and said actuation switch, and a jacket adapted to be attached to an archery bow within which said light source, said power source, said actuation switch, and said circuit are disposed, so that, when said jacket is attached to the archery bow said light source directs light forwardly from said bow toward a target and so that, during use, said actuation switch can be actuated by the same hand that is holding the bow in response to the natural motion of drawing the bow string.

  • Publication number: 20040003529
    Abstract: An illumination device for a firearm having a first hand grip position adjacent to a trigger and a second hand grip forward of the first grip position and having a gripping surface. The device has a first hand grip position adjacent to a trigger for a firearm with a second hand grip forward of the first grip position and having a gripping surface. An illumination source is connected to first the hand grip, and has an optical axis. The optical axis is positioned as an elevated level above a major portion of the gripping surface of the second hand grip, or above a horizontal plane defined by the axis of the barrel. The device may be a laser attached to an upwardly protruding portion of a protruding pistol grip, with an integral switch on the grip, or may be part of a conventional rifle butt stock, with the switch located on a narrowed portion of the stock.

  • Patent number: 5706600
    Abstract: A sighting device for a weapon. The device forms an integral part of the handgun and projects a laser beam onto the impact point of the intended target. The device includes a laser assembly that is preferably disposed adjacent the front of the trigger guard of the handgun. In one preferred embodiment, a laser and laser drive circuit are mounted on a flexible circuit board to accommodate movement of the laser with respect to the laser drive circuit during sight adjustments. Preferably, the laser drive circuit comprises MOSFET devices in analog mode which use comparatively low power. A switch assembly is integrally disposed in a crotch formed between the trigger guard and the handgrip. The power supply may be disposed in the bottom of the handgun's magazine which is in electrical contact with the laser sighting device.
