US Patent 9395158 Mounting device for weapon

A mounting device for mounting an accessory to a rail of a weapon including a base portion, a first side portion configured to engage a first side of a rail of the weapon, and a second side portion configured to engage a second side of the rail. The first side portion has an opening defined therein. A movable clamping member is disposed in the opening in the first side portion so as to be movable between a clamping position where it secures the device to the rail and a retracted position. A clamping lever is pivotally interconnected with the first side portion for movement between an open position and a closed position. A link interconnects the clamping lever and the clamping member such that moving the lever from the open position to the closed position moves the clamping member from the retracted position to the clamping position.
