  • Patent number: 4405223
    Abstract: There is disclosed herein an interchangeable left-to-right pistol grip and bracket device onto which a camera and flash unit can be mounted. A camera bracket attaches to either side of the pistol grip body, and the grip includes a strap for encompassing the hand of the user. The strap also is reversible to the side of the grip body opposite that onto which the camera bracket is placed. The top of the body of the grip includes a shoe for receiving a flash unit. The handle of the pistol grip is disposed at an angle with respect to the body thereof and to a mounting flange for the camera bracket, and thereby provides a more comfortable grip when using either a 35 mm SLR or a medium format (single or twin lens reflex) camera. Furthermore, the grip may include a receptacle therein for receiving batteries, as well as appropriate electrical connections to an on/off switch and outlet power plug. This latter arrangement enables additional power to be supplied to a flash unit attached to the pistol grip.
