Patent ID: 8336246

Claim:
A rail attachment mechanism for securing an auxiliary device to a rail of a weapon, comprising: a mounting structure; a cam secured to the structure and rotatable about a first axis of rotation; and a jaw rotatable about a pin secured to the structure, the pin having a second axis parallel to the first axis, the cam being in contact with a first end of the jaw and rotation of the cam causing a second end of the jaw to come into contact with a surface of a rail of a weapon to squeeze the rail in a direction perpendicular to the first axis of rotation of the cam, the pin being disposed between the first end of the jaw and the second end of the jaw, further comprising a movable portion slidably coupled to the handle, the movable portion has a feature that cooperates with a feature on the structure to prevent rotation of the handle from a “locked” position to an “unlocked” position.
