| 20090217564 | Antidismantling Device for Hand-Guns - An antidismantling device for preventing dismantling of a hand-gun when a cartridge is present in the barrel ( | 09-03-2009 |
| 20100000137 | Handheld single shot firearm - A firearm with a stock having an exterior contour that is generally symmetric with respect to opposing end portions, a front edge portion and at least a portion of opposing side surfaces. A barrel extends through the front edge portion of the stock. Two safety release buttons are diametrically opposed to each other with respect to a barrel bore centerline axis and are exposed at a front edge portion of the stock. Two firing mechanism release buttons are each exposed at an exterior surface of the stock at a respective one of the opposing end portions. The firing mechanism actuation buttons are diametrically opposed to each other with respect to the barrel bore centerline axis. Firing of the firearm requires both of the safety release buttons to be depressed thereby allowing either of the firing mechanism actuation buttons to be depressed for firing the firearm. | 01-07-2010 |
| 20100139142 | FIREARM WITH LOADED / UN-LOADED IDENTIFICATION SYSTEM - An article including an article including a firearm including a safety that moves between a safe position that does not permit firing of the firearm and a fire position that permits firing of the firearm, the firearm further including a light indicator, and a loaded chamber indicator in electrical communication with the light indicator, wherein when the safety moves to the fire position, the light indicator emits a first distinct color if a round is loaded in a chamber of the firearm, and the light indicator emits a second distinct color if a round is not loaded in the chamber of the firearm. | 06-10-2010 |
| 20100192438 | METHOD FOR INDICATING LOADED FIREARM CHAMBER PISTOL WITH LOADED CHAMBER INDICATOR - A pistol including a loaded chamber indicator to identify the presence of a cartridge loaded in the firing chamber. The pistol may generally include a barrel, a receiver attached to the barrel thereby defining a barrel-receiver assembly, and a chamber associated with the barrel-receiver assembly. An indicating element is provided which in one embodiment may be pivotally mounted in the barrel-receiver assembly. The indicating element is displaceable in response to contact by the cartridge from a first position which may in one embodiment correspond to an absence of a cartridge loaded in the chamber, to a second position which may in one embodiment correspond to a presence of a cartridge loaded in the chamber. A biasing member, such as a spring, may be provided to bias the indicating element towards the first position. In one embodiment, the indicating element protrudes outwards from the exterior of the pistol in response to contact by the cartridge rim to provide a visual and tactile indication of a loaded chamber condition to a user of the pistol. | 08-05-2010 |
| 20100229443 | Handgun - A handgun has at least one barrel; a cartridge chamber; a gun lock correlated with the cartridge chamber and provided with a hammer to be cocked against a spring force into a cocked position and with a trigger for releasing the hammer from the cocked position. First and second electric or electronic sensor devices are provided. The first sensor device recognizes whether the hammer is cocked. The second sensor device recognizes whether a cartridge is in the cartridge chamber. At least one light illuminates when the hammer of the gun lock is cocked; when a cartridge is inserted in the cartridge chamber; or when both of these conditions are fulfilled. A mechanical locking and unlocking device acts on the hammer. In a locking position it secures the hammer in the uncocked position. It is electrically operable by a battery and is in the locking position when currentless. | 09-16-2010 |
| 20120297655 | Illuminated Chamber Status Indicator - A self-illuminated chamber status indictor, or simply illuminated chamber status indicator (icsi). The illuminated chamber status indicator makes use of self-illuminating substances. The substances and/or materials could be in the form of radioactive gaseous isotopes, or self-illuminating paint. The illuminated chamber status indicator will leverage in any form of current self-illumination technologies that require no external power source in order to give off light emissions. The illuminated chamber status indicator will use the properties of radioluminescence as a primary, but not exclusive source to create such attributes. | 11-29-2012 |
| 20130180144 | Body Contoured Handgun - A handgun curved to correspond more closely with the contours of a person's body, achieving a comfortable fit when the handgun is worn for any appreciable amount of time on the person's body. The handgun housing is inclusive of a top portion, an intermediate portion, and a grip portion, which may be separately connected or integrally formed parts sharing a radius of curvature to form asymmetric left and right sides, particularly a concave side and a convex side. This asymmetry extends beyond the grip portion and includes at least a portion of the trigger guard and a portion of the magazine securing clip. | 07-18-2013 |
| 20140190051 | Shooter Aim Detection and Warning System - Subject matter disclosed herein relates to an apparatus, device, or method for detecting aim or pointing direction of a firearm, the method comprising detecting a sound signature of a gunshot from the firearm; sensing an aim direction of the firearm substantially at the time of detecting the sound signature of the gunshot; setting a reference direction based, at least in part, on the aim direction; sensing a current aim direction of the firearm; comparing the current aim direction to the reference direction; and initiating an alarm if the current aim direction is beyond a threshold angle of displacement from the reference direction. | 07-10-2014 |
| 20140283426 | Body Contoured Handgun - A handgun curved to correspond more closely with the contours of a person's body, achieving a comfortable fit when the handgun is worn for any appreciable amount of time on the person's body. The handgun housing is inclusive of a top portion, an intermediate portion, and a grip portion, which may be separately connected or integrally formed parts sharing a radius of curvature to form asymmetric left and right sides, particularly a concave side and a convex side. This asymmetry extends beyond the grip portion and includes at least a portion of the trigger guard and a portion of the magazine securing clip. | 09-25-2014 |
| 20150369551 | Illuminated Chamber Status Indicator - A self-illuminated chamber status indictor, or simply illuminated chamber status indicator. The illuminated chamber status indicator makes use of self-illuminating substances. The substances and/or materials could be in the form of radioactive gaseous isotopes, or self-illuminating paint. The illuminated chamber status indicator will leverage in any form of current self-illumination technologies that require no external power source in order to give off light emissions. The illuminated chamber status indicator will use the properties of radioluminescence as a primary, but not exclusive source to create such attributes. | 12-24-2015 |
| 20160018174 | METHODS AND DEVICES FOR SUPERVISION OF FIREARM CHAMBER LOADING - A method of supervising the safe carrying of firearms establishing rules for the situations where live ammunition is allowed to be in the chamber of the firearm. A supervisor checks that a dummy round is in the chamber of the firearm before the supervised person goes on duty outside of direct supervision. The dummy round is designed so that it records occasions when it is removed from the chamber. The recording is designed to last until checked by the supervisor. In some cases the dummy round undergoes changes that make the recording. In other cases the dummy round keeps count of the number of times it is removed from the chamber. In still other cases the dummy round communicates with a device which makes the recording. In each of these cases the system of supervision insures that live ammunition is only chambered when appropriate. | 01-21-2016 |
| 20160076838 | Gun Safety System - A method of multistate labeling a firearm as to the readiness state of the firearm is described. Information as to the readiness state of a firearm is conveyed to a handier of the firearm immediately and accurately regardless of environmental or stress conditions. | 03-17-2016 |
