DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT(S)

Referring to the drawings, a multi-function flashlight assembly, designated generally as 100, is configured for attachment to a weapon 104, such as a firearm, preferably, a handgun. In the illustrated embodiment of FIG. 1, the unit 100 is mounted to a rail interface 108 disposed on a lower receiver portion 112 of the handgun 104 at a position forward of the trigger guard 116. In certain embodiments, the rail interface 108 is a dovetail interface such as a Picatinny interface, e.g., a MIL-STD-1913 or STANAG 2324 rail interface.

Unless specifically stated otherwise, terms used herein denoting direction or orientation, such as left, right, front, rear, forward, rearward, upper, lower, horizontal, vertical, etc., are taken from the perspective of an user operating the unit 100 when the unit is mounted on a weapon, such as the handgun 104 as illustrated in FIG. 1.

As best seen in FIGS. 2 and 3B, the unit 100 includes a rail clamp interface 120 for mounting to the rail interface 108. The rail clamp interface 120 assembly includes a fixed clamping member 124 affixed to a flashlight main housing 128 on one transverse side of the flashlight housing 128. The rail clamp interface assembly 120 further includes a movable clamping member 132 disposed on the opposite transverse side of the flashlight housing 128.

A rod 136 extends through an opening 140 in the fixed clamping member 124 and an opening 144 in the movable clamping member 132. The rod 124 includes helical threads disposed at least at a distal end 148 of the rod 136. The threaded end 148 of the rod 136 rotatably engages a nut 152 (see FIG. 4) aligned with the opening 144 in the movable clamping member 132. The proximal end of the threaded rod 136 includes an enlarged diameter head 150 configured to engage a tool for rotating the rod 136 to selectively advance or retract the rod 136 relative to the nut 152, depending on the direction of rotation. In certain embodiments, the head 150 may include a tamperproof feature, such as keyed feature configured to engage a custom tool.

The rod 136 is configured to extend within a transverse recoil groove 156 in the rail interface 108. Rotation of the threaded rod 136 in one direction increases the clamping force exerted by the clamping members 124, 132, to secure the flashlight assembly 100 to the rail interface 108 and rotation of the rod 136 in the opposite direction decreases the clamping force for removal of the flashlight assembly 100 from the rail interface 108. In certain embodiments, the nut 152 may be omitted and the bore 144 within the movable clamping member 132 may be tapped with internal threads to receive the threaded end 148 of the rod 136. In certain embodiments, the rail clamp interface assembly 120 may include a cam lock having a lever and a cam surface, e.g., by providing an eccentric pivot axis, to allow for removal and attachment of the flashlight assembly without a tool.

As best seen in FIG. 4, the flashlight main housing 128 includes an opening 160 receiving a flashlight socket 164 which, in turn, receives a flashlight head 168 including a light source 170.
