  • Patent number: 10731935
    Abstract: A takedown mechanism for disassembly of a striker-fired pistol, including a takedown release comprising a spring and a pin disposed in the pistol frame adjacent its rear end, the spring to bias the pin towards the barrel end of the frame and disposed against a hard stop on the frame; a takedown bar having a sear contact surface and movable along the longitudinal axis of the frame from a first position to a second position, wherein the takedown release biases the takedown bar towards the barrel end of the frame, wherein, in the first position, the takedown bar is disposed between the takedown release and the slide stop, wherein longitudinal movement of the takedown bar towards the barrel end is limited by the slide stop, wherein, in the second position, the takedown bar is disposed in a forward position toward the barrel end of the frame to cause the sear contact surface on the takedown bar to contact the second leg of the sear to cause the sear to rotate away from the tab of the pistol striker such that the f

  • Patent number: 10731936
    Abstract: A modular grip panel system for a firearm has a frame to support a pair of grip panels and a backstrap. The system includes a left and right grip panels having pockets, and a backstrap having a boss. The frame has a grip disposed at its rear end having a left and right side bosses to engage the pockets of the grip panels, and a rear surface pocket to receive the backstrap boss. The grip panels are disposed on the side surfaces of the pistol-style grip by insertion of the bosses into the pockets. The backstrap is disposed on the rear surface of grip by insertion of the backstrap boss into the rear surface pocket. When the backstrap is secured to the frame, the boss of grip panels are held in a forwardmost position. The backstrap prevents movement of the left and right grip panels towards the rear end of the frame.

  • Patent number: 8919047
    Abstract: A handle assembly for a door of a vehicle includes a housing, and a grab bar moveably supported by the housing. The grab bar is linearly moveable along a linear path between a retracted position and an extended position. The linear path is disposed on a plane. A motor is attached to the housing, and includes an output rotatable about a rotation axis. The rotation axis is perpendicular to the plane. A scotch yoke mechanism interconnects the output of the motor and the grab bar. The scotch yoke mechanism translates rotational movement of the output into the linear movement of the grab bar to move the grab bar between the extended position and the retracted position.
