  • Patent number: 7731380
    Abstract: A weapon mount tactical light trigger includes a mount for Picatinny rail to clamp to a shotgun or rifle, a light mount to clamp a tactical light, and a principle mount to joint both mounts with a trigger base fixed at the back. Components of the trigger base include a trigger to switch on/off the tactical light, a circular shaft to allocate the trigger on the trigger base and a fixing bolt to keep the trigger and switch of the light to stay connected under normal conditions. When a user presses the trigger with a finger, the trigger pivots on the circular shaft and exerts pressure to the switch of the tactical light. The structure design of the trigger base is according to the principle of leverage; via pressing the trigger, it exerts pressure to the switch to turn on/off the light; as the mechanism design of this creation avoids possible shortfall of wire conduction and enhance the performance stability of the tactical light.

  • Patent number: 7685761
    Abstract: A trigger activating tactical light grip includes a Picatinny rail mount to assemble the grip to the firearm, a tactical light mount to mount the tactical light and a grip to provide a place for holding the gun. In the grip, there is a trigger to initiate movement for a connecting rod, and the connecting rod is to deliver the movement of the trigger, a tunnel for the connecting rod to slide along, a circular shaft to assemble the trigger, and a fixing pin to keep the connecting rod to be contacted with the tactical light switch. When a user provides pressure with a finger on the trigger, it pivots on the circular shaft and leads the connecting rod to slide along the tunnel. As a result, the connecting rod exerts pressure to the switch of the tactical light and then the aim of activating the tactical light is accomplished.

  • Publication number: 20090084016
    Abstract: A trigger activating tactical light grip includes a cramp for Picatinny rail to assemble the grip to the firearm, a light cramp to clamp the tactical light and a grip to provide holding place. Wherein the grip, there is a trigger to lead a connecting rod, a connecting rod to deliver the movement of the trigger, a tunnel for the connecting rod to slide, a circular shaft to assemble the trigger, and a fixing bolt to keep the connecting rod connected with the tactical light switch. When a user gives pressure with a hand to the trigger, it pivots on the circular shaft (fulcrum) and leads the connecting rod to slide along the tunnel. As a result, the connecting rod exerts pressure to the switch of the tactical light and then the aim of activating the light is accomplished.

  • Patent number: 5748181
    Abstract: The present invention is related to a method used in a cursor controlling apparatus for detecting a direction a cursor should move on a monitor which comprises steps of: intermittently receiving a light to obtain a series of different optical quantities; generating a series of voltage signals respectively responsive to the series of optical quantities; and determining a direction by detecting a sequence of the voltage signals. The present invention can reduce manufacturing cost, economize assembling time, and obtain a more accurate direction.
