BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to mounting devices for lights attached to a firearm and particularly to adjustable positioning of rail-mounted lights on a firearm.
2. Related Art
Historically, it has been difficult for even skilled marksmen to coordinate a hand held flashlight with a firearm at night. The modern two handed handgun shooting technique requires the support hand to wrap around the hand which controls the firing of the weapon in order to substantially control the weapon during firing. The user must relinquish some control of the handgun if the support hand is used to hold or even switch on and off a light while firing. In recent years the industry has improved upon this skill by incorporating a mounting rail with locking indentions, into the frame of the firearm, inline with and just below the barrel of the firearm. A specially designed light module is attached to the firearm using the integral mounting rail on the firearm. The light module is secured to the firearm's mounting rail just forward of the front of the trigger guard on pistols and near the front of the hand guard or fore stock of shoulder firearms. A light pressure switch is mounted to the grip of the firearm in some designs and in other designs the switches are incorporated into the light module itself. In the later designs, the light modules have momentary and on/off toggle switches incorporated into the rear of such modules. These switches are operated usually with the support hand and must be ambidextrous in design. The toggle type switches require practice and training in order for someone to become proficient with the module while firing the firearm at night while maintaining control of the firearm. In the above referenced designs, the light module is relatively expensive and in some cases, costs near the cost of the firearm. In most designs, the installation and removal of the light unit is not user friendly and a majority of the users dedicate the light module to the firearm. A specially designed holster is then required to fit the firearm with light attached. Common sense and proper training would prevent the user from using the dedicated light in a no risk illumination scenario and therefore a secondary flashlight is required for such uses. The substantial disadvantages of the prior art device require a new approach.

DETAILED DESCRIPTION OF THE PRESENT INVENTION
Objective
The present invention is directed toward an inexpensive device that can use a simple end cap, push button switch operated flashlight such as the Coast “Tac Torch”. The Tac Torch or similarly designed light is first adjusted and locked into place. Then the device with light installed is easily and quickly slipped onto the integral mounting rails of the firearm. The unit is secured in place by rotating the light either to the right or left side of the frame of the firearm. A right hand shooter, using a modern two handed shooting technique, would position the light to the left of the frame and vice versa for a left handed shooter. The device, after adjustment, would align the end cap switch of the light such that it can be operated by the thumb of the support hand without affecting the necessary two handed grip. The shooter can engage the push button for momentary illumination or can depress it all the way for the on position. The device can easily and quickly be removed from the firearm so that in cases where it is used with a handgun, the handgun can be quickly reholstered in a standard holster. Because of the simple nature of the device, the operator could use the detached device as a standard flashlight, eliminating the need of having to carry a second light. A further design objective of this invention is the incorporation of a simple belt clip to the device itself so that it can be easily stored on the user's belt when it is detached from the firearm.
Introduction
The adjustable rail light mount is composed of two main components. One component secures the small cylindrical flashlight and the second component mates to the integral rail portion of the frame of a handgun or the fore grip of a shoulder firearm. The two components cooperate via an extended arm adjacent the light component and held to the frame mating component by a pivoting axle. The axle has one or more small lobes or detent bosses that match indentions in the receiver portion of the light component so that the light can be indexed in position. A locking tab is incorporated on either side of the extended arm of the light component in such a way that when the light component is pivoted in full position to the right or left, the locking tab is aligned with a locking slot provided by the firearm. This secures the device on the firearm so that it cannot come off during use. Through the use of a frictional lock, the light component is held in position to the right or the left in such a way to align the push button switch with the user's support thumb. The light can be adjusted fore and aft in the light component so that the user can activate the push switch by the support hand thumb without disturbing the modern two handed shooting technique. An added feature is a belt clip incorporated into the light component so that it can be easily stored on the user's belt when the mount and/or light is detached from the firearm.
Construction
With respect now to the drawings, FIGS. 1-3 illustrate the adjustable rail light mount 10 in accord with the present invention and is shown rotated and locked to the left for a right hand grip (FIG. 1); rotated and locked to the right for a left hand grip (FIG. 2); and a releasable center position below the gun (FIG. 3).
FIG. 4 illustrates the light mount 10 being installed on a firearm 11 having a standard integral rail portion 12 as understood in the art.
FIG. 5 illustrates the components of the rail light mount. A conventional flashlight frictionally carried in rotatable light mount 14 and is secured into place by tightening screw 13. The light mount rail body 16 engages a rail 12 having a rail slot 12A and cooperates with a locking axle 17 for selectively rotatably connecting a light mount 14 to rail body 16, as will be discussed more fully hereinafter.
Light carrier 14 (FIGS. 6-13) includes a cylindrical body 18 having a interior space 19 to slidably mount light 15. Inwardly directed flange 20 limits forward movement of light in body 18. Flanges 24 and 24A are spacedly opposed and respectively have a passage 21 and aligned threaded passage 21 A through which screw 13 extends and tightens light carrier 14 around light 15.
A laterally extending post portion 22 includes a passageway 23 with axis 23A therethrough for receiving locking axle 17 which is secured to body 16. Post portion 22 includes front and rear surface 34, 35 respectively.
Rail body 16 (FIGS. 14-20) includes an arcuate opening 36 for selectively receiving either of flanges 33 therethrough into rail slot 12A. A space 27 defined between subtending flanges 26 has respective interior surface 26A both aligned around axis 23B. Post 22 closely fits within space 27 and is rotatable to three positions (FIGS. 1-3). Body 16 includes a rail channel 40 defined by walls 38 and bottom 39 that works with all standard pistol or Picatinny rails (see FIG. 18 and enlarged portion in FIG. 20). Rear surfaces 43 of body 16 are formed to rest against most trigger guards (FIG. 16).
Grooves 41 in rail body 16 are aligned and cooperate with grooves 37 in body 18 for selectively positioning mount 14 as shown in FIGS. 1-3.
FIGS. 21-26 illustrate the mount 14 and rail body 16 connected together and mounted on a standard rifle Picatinny rail 42.
FIGS. 27-32 illustrate locking axle 17 having an elongated body 30 with a front portion 44 and a rear portion 45. Front portion 44 includes an arcuate surface 46. The locking tab 29 has an inclined surface 47 that is undercut or flush with rear surfaces 43 of rail mount 16 so as not to interfere with contact with the trigger guard. Three detent bosses 48 extend substantially the length of body 30. A rear detent boss 49 extends outwardly a greater distance than bosses 48 and the bottom groove 41 is deeper than the other grooves 41 to accommodate boss 49.
FIG. 33 illustrates the release position for the rail mount in that rail locking tab 33 is not engaged in slot 36 and rail slot 12A. When the light mount 10 is in a down center position, the mount 10 may be easily and rapidly removed from the firearm 11.
FIG. 34 illustrates rail locking tab 33 extending through slot 36 and into rail slot 12A when the mount 10 is rotated to place rotational light carrier 14 on the right side. When moved to the left the other tab 22 also will fit into slot 36 and slot 12A. In both cases, the mount 10 is held in a manner to prevent forward or rearward movement of the mount 10 with respect to the firearm.
The rotation of carrier 14 causes detent bosses 48 to move in aligned grooves 37 and 41 when carrier 14 is rotated and lock carrier 14 in a selected position. Locking tab 29 fits within walls 26B (FIG. 15).
Operation
The light mount 10 is assembled as shown in FIG. 5. Locking axle 17 is installed by having a tapered end portion 49 being press fit into rear passageway 26A in rail mount in rail mount 16 after the upper portion of light carrier 14 is placed in the space 27 of body 16 to align both axes 23A and 23B. Light 15 is inserted into carrier 14 either before or after the installation of light carrier 14 into rail mount 16. Screw 13 moves flanges 24 toward each other to frictionally engage a light 15 at a desired location and to dispose the light switch at the desired location as shown in FIG. 43. Rail body 16 is then slipped onto rail mount 12 (FIG. 4) or 42 (FIGS. 21-26).
Carrier 14 can then be rotated to either the right or left with a locking tab 33 preventing mount 10 from moving forward when light operating button 32 is depressed by a user. The mount 10 can be moved to the down center position for quick removal if desired.
As discussed hereinabove, mount 10 is easily installed or removed form gun rail 12, 42. FIGS. 35-39 illustrate a belt clip 50 employed to carry the mount 10 when it has been removed from a firearm 11.
Clip 50 includes a cylindrical body member 51 that can be compressed via a screw 52 through a passageway 53 and a threaded passageway 54 as well understood in the art. Integral arm member 55 includes a curved end portion 56 to engage a belt in the space between the top portion 57 of body 51 and the underside surface of arm member 55.
FIGS. 40-42 illustrates the versatility of clip 50 being attached to a representative flashlight 15 not mounted in a carrier 14.
FIG. 43 illustrates the use of the light mount of FIGS. 1-34 carrying belt clip 50. The relative dimensions and positioning of clip 50, light 15 and carrier 14 may be varied on the desires of the user. This also shows the positioning of the trigger hand and other hand of the user in operating the light switch and pulling the trigger in a two-handed stance of the user.
While the invention has been described with respect to certain specific embodiments, it will be appreciated that many modifications and changes may be made by those skilled in the art without departing from the spirit of the invention. It is intended, therefore, by the appended claims to cover all such modifications and changes as fall within the true spirit and scope of the invention.
