Description:
BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates generally to firearms and more particularly to firearm sighting devices. Even more specifically the present invention concerns a pivot mount by which a particular firearm sighting device, such as an optical or laser sighting device is releasably mounted to the sight mounting rail of a tactical firearm by a locking lever operated clamp mechanism and, when so mounted, a sight support portion of the mount is pivotally moveable between an operative position at which the sighting device is useable for the purpose of sighting on a target and an inoperative position at which the sighting device is positioned out of the normal line of sight of the firearm. The present invention also concerns a pivot mount for a firearm sighting device or other firearm related implement that is adapted for manual unlocking and pivotal movement, without necessitating the use of any tools or other equipment.  . . . .

Abstract:
A pivot mount base is assembled to or removed from the sight mounting rail of a firearm by a lever actuated cam energized rail clamping mechanism. The pivot mount base supports and provides for rotational and linear movement of a pivot shaft. A pivot shaft locator pin extending transversely through the pivot shaft is adapted to be selectively received in position controlling relation by pairs of aligned shaft location receptacles defined by the pivot mount base. A sight support device is fixed to the pivot shaft and serves to retain a firearm sighting device. The sight support device and sighting device are moveable between an operative position where the sighting device can be used to sight the firearm on a target and an inoperative position where the sighting device is positioned laterally offset from its operative position. The sight support device is pivotally mounted by the pivot shaft and is spring energized to sec . . . . More
Claims:
I claim:

1. A pivot mount mechanism for a firearm sighting device, comprising: a mount base adapted to be secured in substantially fixed relation on a firearm and defining pivot shaft location depressions, said mount base defining spaced sections each defining a pivot shaft bore; a pivot shaft being supported by said mount base and being rotationally and linearly moveable relative to said mount base and defining pivot shaft location surfaces disposed for pivot shaft rotational positioning engagement with said pivot shaft location depressions, said pivot shaft having end portions pivotally mounted for rotational and linear movement within said pivot shaft bores; a sight support member being fixed to said pivot shaft and being rotationally and linearly moveable with said pivot shaft and being rotationally and linearly moveable between said spaced sections of said mount base, said sight support member supporting a firearm sighting device; said pivot shaft being selectively pos . . . .
