The invention relates generally to an auxiliary (e.g., illumination) device for a weapon and, more particularly, to attaching an auxiliary device to a weapon.
The need to be able to effectively see a target and aim a weapon in the direction of the target is well recognized. Auxiliary devices to facilitate illuminating a target or aiming a weapon, especially under low light conditions, are known. Examples of known auxiliary devices include scopes, illuminators, lasers, aiming lights and combined illuminator/laser units. For convenience, these (and other) devices are generally referred to herein as auxiliary devices. Attaching auxiliary devices to a weapon typically requires separate brackets or other mechanical components, which may necessitate tools, e.g., screwdrivers, coins, hex wrenches or bullets, for attaching the auxiliary device itself or the mechanical component. Alternatively, attaching and detaching the device or mechanical components to the weapon requires partial disassembly or modification of the weapon. Further, such systems typically require use of two hands to mount the device on the weapon, with both hands performing a function beyond merely gripping the weapon. This requirement presents several disadvantages. For instance, the user may be required to remove the trigger hand from the trigger area of the weapon. Moreover, attachment and detachment of these devices can be time consuming and, in law enforcement and military applications, such time may be critical to the safety of the weapon's operator or others.
As a result of these and other problems with conventional devices, the user typically leaves the auxiliary device mounted on the weapon or performs a time consuming operation to mount the device when needed. These alternatives are undesirable. For example, if the device is left mounted on the weapon, it cannot be used independently of the weapon despite the fact that in some situations, it is desirable to illuminate an area without pointing a weapon toward that area. Also, in the context of handweapons, for example, many holsters do not readily accommodate weapons having auxiliary devices mounted thereon. Thus, it is often difficult to holster or carry a weapon having such a device attached to it. This presents special problems for law enforcement officers and others. Additionally, the user may not want to use the device during daylight hours, but may want to attach the device to a weapon at night. Further, the user may want to be able to readily remove the device when it is no longer needed. Moreover, depending on the configuration of the auxiliary device, the user may need to replace its batteries. Preferably, the user should be able to perform this procedure quickly without the need for tools.
Another problem with conventional auxiliary devices is that the device is often wider than the weapon, or the device protrudes beyond the front end of the weapon. In the case of handweapons, a device mounted below the frame may protrude below the trigger guard. These characteristics often result in subjecting the auxiliary device to greater wear and tear because the auxiliary device often contacts various obstructions in the environment where the weapon is being used. For instance, a device extending beyond the end of a barrel of a weapon may collide with doorways, clothing, tree branches, or other objects, tending to tear the device apart from the weapon and possibly damaging, or rendering inoperable, the device or the weapon itself. Another problem is that an assailant may more easily disarm a user by grabbing an auxiliary device which extends substantially beyond the weapon. The danger of these and other problems occurring are greater at night or when ordinary vision is impaired.
Additionally, many prior auxiliary devices, especially illuminators, are bulky. This characteristic also is undesirable.
U.S. Pat. No. 5,430,967 addresses some of these issues for an auxiliary device for a weapon. The device described therein is provided with a clamping mechanism for attaching an auxiliary apparatus to a weapon having a frame. The clamping mechanism has projections which are biased by a flexible member toward corresponding recessed portions formed in the frame of the weapon. A retaining member is also provided. The retaining member may be moved to between an open and a closed position. While the '967 Patent overcomes some of the problems traditionally associated with the attachment of an auxiliary device to a weapon, it too leaves room for improvement.
For example, the existence of a flexible biasing mechanism results in the auxiliary device being somewhat flexibly attached to the weapon. This flexible attachment is not ideal in some circumstances, for example, for use with auxiliary devices requiring precise boresight alignment. Also, the attachment mechanism is relatively bulky, causing the auxiliary device to be relatively wider, resulting in an increase in the size of the device in at least one dimension. Moreover, the engagement of portions of the auxiliary device with the corresponding portions of the weapon is limited by the degree of flexibility of the flexible mechanism. Furthermore, the spring-loaded mechanism also limits the biasing force holding the auxiliary device to a weapon. As a result, this attachment approach may be successful on weapons, such as handweapons, which have relatively modest recoil forces, but may be somewhat less successful on other weapons, such as shotguns, where the greater recoil forces may cause the auxiliary device to dislodge from the weapon.
While lights and other devices primarily have been mounted to weapons, many weapons are not specifically designed to facilitate this. As a result, special brackets and other mounting devices often need to be used. Some weapons have mounting racks, but various drawbacks exist even with these types of devices. In many cases, it is difficult to mount a device to the weapon and/or complex mechanical structures are necessary.
Gun owners may own two or more weapons and the distance from the front of the trigger guard to the transverse slot located along the lower surface of the dust cover may be different for each weapon. This difference in dimension may cause an auxiliary device not to fit on to the weapon because the back end of the auxiliary device contacts the front surface of the trigger guard before a spring-biased mechanism can engage in the transverse slot. Alternatively, the difference in dimension may cause the auxiliary device to unnecessarily extend past the end of the weapon. Auxiliary device manufacturers have typically produced distinct auxiliary devices that are designed for a particular weapon. Gun owners, however, want a single auxiliary device that can be easily mounted to any of their weapons. An alternative to having multiple auxiliary devices is a single auxiliary device with multiple spring-biased mechanisms that can be swapped in when needed. This requires the owner to store a second part and adds to the manufactured cost.
Rail dimensions differ from manufacturer to manufacturer. This can cause an auxiliary device to fit nicely on some weapons and either be too tight or too loose on another weapon.
Other problems and drawbacks with prior approaches exist.
One object of the invention is to overcome these and other drawbacks of known devices.
Another object of the invention is to provide a weapon and auxiliary device system that includes complementary mounting members on the weapon and on the auxiliary device to enable the auxiliary device to be easily and securely attached to the weapon, for example, by relative sliding movement.
Another object of the invention is to provide a weapon and auxiliary device system that includes complementary mounting members on the weapon and on the auxiliary device to enable the auxiliary device to be easily and securely attached to the weapon, for example, by relative sliding movement to a predetermined position, and which further includes a mechanism to fix the auxiliary device in the predetermined position.
Another object of the present invention is to provide an auxiliary device such as an illuminator or aiming light, or combination thereof, with a mechanism for attaching the device to a weapon and particularly a handweapon, such that the actual attachment or removal can be accomplished by a user with one hand, while the second hand is free to grip the weapon.
Another object of the invention is to provide a mechanism for attaching an auxiliary device to a weapon such that the device will maintain or better maintain boresight alignment even after the shocks of repeated weapon fire recoils.
Another object of the invention is to provide a mechanism for mounting an auxiliary device to a weapon without temporary or permanent disassembly or removal of any parts from the weapon to which the device is attached.
Another object of the invention is to reduce or minimize the size of an auxiliary device, for example, by providing an auxiliary device which may be attached to the frame of a weapon such that when the device is attached to the weapon, protrusion of the device beyond the overall dimensions of the weapon is reduced or minimized. Preferably, the width of the auxiliary device does not extend beyond the overall width of the weapon to any appreciable degree. Also, the auxiliary device has minimal or no protrusion beyond the front end of the weapon.
Another object of the invention is to provide a battery operated auxiliary device in which the batteries can be easily and readily replaced and such replacement can be performed without tools.
Another object of the invention is to provide a weapon comprising a frame to which an auxiliary device can be easily attached to and removed from the weapon by a user with one hand, while the second hand is free to grip the weapon (without tools) and when attached will hold boresight alignment to a high degree of precision.
These and other objects may be carried out according to various embodiments of the invention. According to one embodiment, the invention comprises a weapon and auxiliary device system that facilitates attachment of the auxiliary device to the weapon and removal therefrom. Preferably the auxiliary device may be attached to the weapon by relative sliding movement therebetween, to guide the auxiliary device to a predetermined position. According to one aspect of the invention, the system preferably further includes a mechanism for maintaining the auxiliary device in the predetermined position, for example, by providing a mechanism that automatically fixes the position once the predetermined position is reached. One advantage of this combination is that, once mounted, undesired movement of the auxiliary device relative to the weapon (e.g., due to recoil shock caused by firing the weapon) can be reduced or eliminated. Another advantage is that the auxiliary device can be easily mounted to or removed from the weapon with single-handed operation without tools. Various aspects of the invention relate to the system. Other aspects may be used alone on a weapon or an auxiliary device.
According to one embodiment, the auxiliary device comprises a housing with mounting members extending therefrom. The mounting members preferably, but not necessarily, are complimentarily-shaped with respect to mounting members of the weapon to which the auxiliary device is to be attached. Preferably, the mounting members are designed to provide a first positioning mechanism, where one is a male member and the other is a female member, spaced and oriented such that the auxiliary device may be mounted to the weapon by relative sliding movement between the weapon and auxiliary device to a predetermined position.
According to another aspect of the invention, the weapon and auxiliary device are provided with a second positioning mechanism. In one embodiment, the second positioning mechanism includes a male portion and a female portion. For example, a spring-loaded bar at the top of the auxiliary device may project for engagement into a transverse slot in the bottom of the weapon frame to prevent the auxiliary device from sliding forward or aft, e.g., when the weapon fires. Alternatively, the second positioning mechanism may include an opening on the weapon frame and a complementary projection on the auxiliary device that is engagable with the opening. Other alternatives exist. For example, the weapon alone may have a latch that engages a portion of the auxiliary device when in a predetermined position.
In any of the embodiments the male portion of the second positioning mechanism may include a biasing mechanism, e.g., a spring-biased mechanism, whereby the user manipulates a latch, button or other release mechanism which, under the influence of a spring or other biasing device, is typically maintained in a normally locked or a normally unlocked position. The spring-loaded projection may be contoured such that the auxiliary device can slide onto the weapon without having to manually depress the projection.
To remove the auxiliary device from the weapon, the spring biasing the second positioning mechanism is manually depressed (or otherwise moved) to allow disengagement of the second positioning mechanisms. Then, the auxiliary device may be slid forward for removal from the weapon.
In another embodiment, the grooves or tongues along the side of the weapon frame are not parallel to the frame and may or may not be parallel to each other. For example, the grooves can be located at an incline or angle with respect to the axis of the barrel of the weapon. In another embodiment, the grooves or tongues may be replaced by other suitable complementary engaging surfaces which allow relative sliding motion between the frame of the weapon and the auxiliary device.
In another embodiment, the grooves or tongues along the side of the weapon frame may be replaced with a rail along the bottom of the frame. A transverse slot or hole may be located in the bottom or side(s) of the rail.
In another embodiment, the male portion (e.g., bar or pin) is not spring-loaded. Rather it is mechanically moved to engage the female portion (e.g., slot or hole) in the bottom of the weapon frame and is mechanically lowered or allowed by gravity to fall to disengage the slot or hole when removal of the auxiliary device from the weapon is desired.
According to one embodiment of the invention, a weapon frame is provided with a pair of elongated side rails of a predetermined geometry formed along opposite sides of the frame extending from forward of a trigger guard to about the forward most end of the barrel. An auxiliary device comprising a housing is provided with structural members that extend from or form part of the housing, and have a predetermined geometry to enable the auxiliary device to mate with the rails of the weapon for attachment thereto. These structures cooperate to locate and align the auxiliary device at a predetermined position with respect to the weapon.
According to another aspect of the invention, the predetermined position of the auxiliary device with respect to the weapon may be fixed by providing a second positioning mechanism on one or both of the weapon or auxiliary device to prevent or reduce mounted undesired movement of the auxiliary device relative to the weapon (e.g., due to recoil shock caused by firing the weapon). This mechanism may include a female portion and a male portion. For example the female portion may comprise a recess, transverse slot, circular opening or other female portion, formed in the bottom of the frame forward of the trigger guard. The male portion may comprise a pin, bar elongate projection or other male portion on the auxiliary device. The male portion may be biased to at least partially enter the female portion in the weapon frame once the predetermined position is reached. Preferably, the second positioning mechanism may lock the auxiliary device to the weapon frame without manipulation of that mechanism by the person attaching the auxiliary device to the weapon. Alternatively, the second positioning mechanism may tend to prevent the movement of the auxiliary device, without locking it to the weapon frame. In this case, the second positioning mechanism could include, for example, a detent ball mechanism or other structure.
According, to one embodiment, the auxiliary device is slid onto the frame of a weapon (in a first direction) via the first positioning mechanism and a second positioning mechanism is actuated to fix the position of the auxiliary device relative to the frame in at least the first direction. The second positioning mechanism preferably includes one component that moves in a direction perpendicular to the first direction.
Preferably at least a portion of the second positioning mechanism comprises a spring-loaded projection that projects from either the auxiliary device or the weapon, into a portion of the other, without having to manually depress the projection. This facilitates the ease with which an auxiliary device can be reliably secured to a weapon. To remove the auxiliary device from the weapon, the spring biasing the second positioning mechanism is manually depressed (or otherwise moved) to allow disengagement of the second positioning mechanism. Then, the auxiliary device may be slid forward for removal from the weapon.
According to one embodiment, an illumination device has a spring-biased mechanism movable between a first position in which the spring-biased mechanism is engageable in a transverse slot disposed on the frame of a weapon to resist movement along a longitudinal axis and a second position in which the spring-biased mechanism is spaced from the transverse slot so as not to resist movement of the illumination device along the longitudinal axis.
According to another embodiment, the auxiliary device has a spring-biased mechanism that enables it to be secured to weapons having different dimensions from the front of the trigger guard to the transverse slot along the lower surface of the dust cover.
According to another embodiment, the auxiliary device has a rotatable member that can accommodate a range of rail dimensions and has a locking mechanism for preventing rotation of the rotatable member.
According to another embodiment there is provided an illuminator for use with a weapon having a trigger guard. The illuminator may include a housing having a longitudinal axis, the housing at least partially enclosing a battery and supporting a first and a second movable actuator mechanically coupled to the housing. The first actuator moveable in a first general direction, independent of the second actuator, to cause a light emitter coupleable to the battery to turn on and stay on and moveable in a second general direction, independent of the second actuator, to cause the light emitter to turn on as long as the actuator is actuated, and the second actuator moveable in the first general direction, independent of the first actuator, to cause the light emitter to turn on and stay on and moveable in the second general direction, independent of the first actuator, to cause the light emitter to stay on as long as the actuator is actuated.
Other objects, features, and advantages of the embodiments will become readily apparent when the detailed description of the embodiment is read in conjunction with the drawing figures.

According to one embodiment, weapon 20 comprises a weapon frame 21 with rails or grooves 22a and 22b, located in and extending along at least a portion of the weapon frame 21, preferably parallel with an axis 23 of the barrel 24. Preferably, the rails extend from about a trigger guard 30, to substantially the forward most end of frame 21. The weapon frame 21 also preferably includes a slot (or other recess), for example, an elongate transverse slot 25, aligned substantially perpendicular to the rails 22a, 22b. The slot 25 is preferably located between trigger guard 30 and the forward most portion of the frame 21.
Auxiliary device 10, as shown in
The auxiliary device 10 preferably further comprises a projection, e.g., spring-loaded elongated bar 6 (
In the embodiment of
The mating of longitudinal tongues 5a, 5b and grooves 22a, 22b provides alignment of the auxiliary device 10 with the weapon barrel 24 and stability in the horizontal and vertical directions. Additionally, the tongues and grooves constrain the auxiliary device 10 in roll, pitch and yaw relative to the weapon. The second positioning mechanism (e.g., engagement of the transverse bar 6 and slot 25) prevents the auxiliary device 10 from sliding forward or aft during use and particularly during weapon fire due to weapon recoil.
According to another embodiment, male portions (e.g., longitudinal tongues 5a, 5b) may be located on the weapon frame and the female portion (e.g., longitudinal grooves 22a, 22b) may be located on the auxiliary device 10. The geometry of the portions making up the first and second positioning mechanism need not be exactly as disclosed. Various other geometries can be used to accomplish the above-identified objects of the invention.
For example, transverse slot 25 and the transverse bar 6 can be replaced by any other engaging devices position fixers, and/or position fixer receptacles, which tend to prevent relative movement of the auxiliary device 10 with respect to the weapon frame. For instance, a recessed counterbore may be formed in the weapon frame and a pin provided in the auxiliary device 10 such that the pin engages the counterbore when the auxiliary device 10 is installed on the weapon. A spring biased latch may project downwardly from the front portion of the weapon to lock over an edge portion of the auxiliary device, once in a predetermined position, to prevent relative movement. For example, such a latch may fix the position of the auxiliary device between the latch and the trigger guard. In this way, only the weapon needs to be provided with a second positioning mechanism. Other alternatives can be used.
The latching mechanism 66 preferably has at least one end of which is accessible by the weapon operator and may be manually manipulated to overcome the biasing force of cantilevered spring 70. When removing the auxiliary device 10 from the weapon, the user pulls the transverse bar 66 downwardly to overcome the influence of cantilevered spring 70. Cantilevered spring 70 then tends to come into contact with tapered surface 72, at which time transverse bar 66 is freed from slot 25 and the auxiliary device 10 may be slid forwardly and removed from the weapon.
Another aspect of the embodiments of
As will be readily appreciated by those of ordinary skill in the art, the mechanisms for attaching the auxiliary device to the frame of the weapon may take different configurations. In a generic form, the auxiliary device is attached to the weapon frame using a first positioning mechanism and a second positioning mechanism. The first positioning mechanism preferably comprise complementary engaging surfaces on the auxiliary device and weapon frame. In a specific embodiment disclosed above, these complementary engaging features comprise longitudinal tongues 5a, 5b on the auxiliary device and complementary grooves 22a, 22b on the weapon frame 21. Other complementary engaging surfaces on the auxiliary device 10 and weapon frame 21 are readily contemplated by the embodiments of the invention. For example, the relative positioning of the tongues and grooves may be reversed such that the weapon frame 21 is formed with tongues, whereas the auxiliary device 10 is formed with complementary grooves. The first positioning mechanism may comprise other suitable complementary engaging mechanisms.
The second positioning mechanism preferably comprises a device which, under normal conditions, sufficiently retains the auxiliary device in a predetermined position relative to the weapon frame. The second positioning mechanism is preferably designed to secure the auxiliary device against movement when the weapon is subjected to recoil forces and other jarring influences which may be expected to be encountered in use and in the field. The second positioning mechanism in the embodiments has been described with respect to a biased transverse bar 6 which engages with an elongate slot 25 formed in the weapon frame. The second positioning mechanism of this particular embodiment acts to prevent the auxiliary device from movement during use. However, other second positioning mechanisms are within the scope of the invention, including spring biased bars or pins or other structures that engage a feature of the weapon from the side or sides or from below, detent mechanisms, latching mechanisms, locking mechanisms and other suitable mechanisms which releasably secure two relatively sliding parts.
For example, the second positioning mechanism may include the weapon barrel being formed with a recessed counter-bore into which a corresponding biased member, e.g., a ball bearing or a post, formed on the auxiliary device may be inserted. As drawn in
Another aspect of the invention relates to the mounting members, e.g., grooves 22a, 22b, formed along the weapon frame. Preferably, the grooves extend from a point substantially at the trigger guard to the front of the weapon. These grooves 22a, 22b or other mounting members extend along the weapon frame to securely hold and retain the auxiliary device with respect to the weapon and facilitate locating the auxiliary device thereon. This further allows the secure fastening of the auxiliary device to the weapon frame without the use of spring hinges or other such devices which could result in the inadvertent dislocation of the auxiliary device from the weapon frame. The complementary mounting members comprising the first positioning mechanism thus form a rigid and secure mechanism for mounting the auxiliary device to the weapon frame.
In various embodiments depicted, grooves 22a, 22b are depicted as extending substantially parallel to the axis 23 of barrel 24. The invention, however, is not so limited. For instance, grooves 22a, 22b may be positioned at an incline with respect to the longitudinal axis 23 of barrel 24. Alternatively, grooves 22a, 22b may be replaced other suitable engaging surfaces which allow relative sliding motion between the weapon frame 21 and the auxiliary device 10.

As noted in the Background, the distance from the front surface of the trigger guard to the transverse slot located along the lower surface of the dust cover of a pistol may differ from one weapon to the next.
The auxiliary device 800 includes a housing 804 which may have structural members 808 that extend upward from a side of the housing 804 and extend longitudinally along at least a portion of the housing. The structural members 808 may have grooves and/or tongues extending along at least a portion of the auxiliary device 800 that cooperate with rails on the weapon. The housing 804 may house one or more batteries 830 and a source of illumination 832.
A spring biased mechanism may include a spring biased ball bearing or post, a retractable bar, or other structure which engages the transverse slot TS, TS' on the weapon. In each of the foregoing and other embodiments, depending on the application, the spring-biased mechanism may be designed to lock or otherwise secure the auxiliary device with respect to the weapon frame or alternatively may, such as in the case of a detent mechanism, simply act to deter, but not completely prevent, relative movement between the auxiliary device and the weapon frame under abnormal conditions. For example, a detent could be of sufficient retention capability to resist relative movement due to weapon recoil forces but not be so strong as to prevent deliberate removal of the auxiliary device from the weapon, without first “un-locking” it.
However, other second positioning mechanisms are within the scope of the invention, including spring biased bars or pins or other structures that engage a feature of the weapon from the side or sides or from below, detent mechanisms, latching mechanisms, locking mechanisms and other suitable mechanisms which releasably secure two relatively sliding parts.
The spring-biased mechanism 802 may be secured in two or more positions along a top surface of the housing 804 and may be biased in a direction normal to the top surface of the housing 804. By repositioning the spring-biased mechanism 802 along the longitudinal axis LA of the weapon W the user can easily mount the auxiliary device 800 to weapons having differing dimensions from the front surface of the trigger guard TG to the transverse slot TS. The spring-biased mechanism 802 may be capable of being coupled to a first fixturing mechanism 810 for locating the spring-biased mechanism 802 in a first position along the longitudinal axis LA and may be capable of being coupled to a second fixturing mechanism 812 for locating the spring-biased mechanism in a second position along the longitudinal axis LA. The fixturing mechanisms may include, but are not limited to, a slot, opening, pin, or suitable fastener. The first fixturing mechanism 810 may be spaced from the second fixturing mechanism 812 by a distance (d1−d2). The spring-biased mechanism 802 may be metallic, for example, spring steel, plastic, or a combination of metal and plastic. Alternatively, the spring biased-mechanism may be rigid and may be biased by a spring 822, for example a compression or leaf spring.
The spring-biased mechanism 902 may have a first side 902A having a first protuberance 906A spaced a first distance d1 from a first end of the auxiliary device 900 and a second side 902B having a second protuberance 906B spaced a second distance d2 from the first end of the auxiliary device 900. The protuberances 906A, 906B may be sized to fit in a transverse slot TS, TS' respectively along the lower surface of the dust cover of a weapon. The width and profile of the protuberances 906A, 906B may be the same or may be different. The spring-biased mechanism 902 may be biased by a spring 922, here a coiled spring. In other embodiments, the spring can be in the form of a compression, leaf, or cantilever spring. One end of the spring-biased mechanism may be captured by and rotatable about a pin 912 coupled to the housing 904 and may be retained by one or more plates 914 and fasteners 916. The spring-biased mechanism 902 may include one or more end portions 920 for assisting in the removal of the auxiliary device 900 from the weapon. The end portions 920 may extend beyond at least one of the first structural member 908A and the second structural member 908B.

Auxiliary device 1100 includes a housing 1104 which may house a power source, for example, one or more batteries, and a source of illumination, for example an incandescent filament or an LED. The housing 1104 may be molded or machined and have a first structural member 1106A that extends upward from a first side of the housing and extends along at least a portion of a length of the first side of the housing 1104. The first structural member 1106A may extend generally parallel with a longitudinal axis (LA) of the auxiliary device 1100 for engaging cooperating rails on the weapon. When installed, the longitudinal axis of the auxiliary device 1100 may be parallel with the longitudinal axis of the weapon. The housing 1104 may have a second structural member 1106B and a third structural member 1106C. The structural members 1106A, 1106B, 1106C may be fixed so as not to move relative to the housing 1104.
Coupled to the housing 1104 or the second structural member 1106B and the third structural member 1106C may be a rotatable member 1108 for engaging the rail 1102 on the weapon. The rotatable member 1108 may rotate about the longitudinal axis of the auxiliary device 1100 and may be secured, for example, with a pin or suitable fastener 1110 positioned within holes 1110A extending through housing 1104 or structural member 1106B and rotatable member 1108. The rotatable member 1108 may extend along at least a portion of a length of the second side of the housing 1104 and be substantially parallel to the first structural member 1106.
The rotatable member 1108 may be movable from a first “locked” position (see
For example, referring to
A positioning mechanism 1114 may be coupled to the housing 1104 to assist in preventing movement of the auxiliary device along the longitudinal axis of the rail 1102, for example during weapon shock. The positioning mechanism 1114 may be biased by one or more springs 1116 to move the positioning mechanism 1114 in a direction normal to the top surface of the housing for engagement into a cooperating cross slot on the weapon. The positioning mechanism 1114 will be discussed in more detail below. Alternatively, the positioning mechanism may be fixed to or part of the housing 1104.
Rotational positioning of the rotatable member 1108 may be restricted by a locking member 1120. The locking member 1120 may have an axis aligned with the longitudinal axis of the auxiliary device 1100 and have a tapered first end 1120A. The tapered end 1120A of locking member 1120 may be configured to cooperate with a tapered opening 1130 in the rotatable member 1108. Alternatively, the rotatable member 1108 may have a surface that cooperates with the first tapered end 1120A. The tapered end 1120A may be at an angle of less than 45 degrees with the longitudinal axis, for example, 5-30 degrees. A second end 1120B of the locking member 1120 may be coupled to a lever 1122 having a contoured surface 1132. The third structural member 1106C may include an opening 1134. The opening 1134 may include a first portion sized sufficiently large to permit the second end 1120B of the locking member 1120 to move longitudinally, but sufficiently small to stop the tapered end 1120A from passing through the opening and a second end sized sufficiently to permit the tapered end 1120A hide therein. The locking member 1120 may slide or may be guided along a spiral path as it moves longitudinally. A biasing member 1124, a washer 1126, and a retainer 1128 may be assembled to urge the lever 1122 towards the third structural member 1106C.
As the lever 1122 is rotated upward (as shown in
With the tapered end 1120A of the locking member 1120 at least partially withdrawn from the opening 1130 in the rotatable member 1108, the rotatable member 1108 can rotate. To secure the auxiliary device 1100 to the rail 1102, the installer may rotate the lever 1122 upward withdrawing the locking member 1120 from the opening 1130. The auxiliary device may then be positioned along the longitudinal axis of the rail 1102 with the positioning mechanism 1114 aligned with a transverse slot located on the rail 1102. The installer may align the first structural member 1106A with an edge 1102A of the rail 1102 and then rotate the auxiliary device 1100 onto the opposing edge 1102B. As the auxiliary device 1100 is rotated onto the rail 1102, the biasing force of the first biasing member 1112 may be overcome, thereby allowing the lip portion 1108A to rotate outward and around the edge 1102B of the rail 1102. The first biasing member may urge the lip portion 1108A of the rotatable member 1108 to remain in contact with the rail 1102. The lever 1122 may then be rotated downward urging the locking member 1120 into the opening 1130 and the surface of the tapered end 1120A into contact with the inside surface of the opening 130 in the rotatable member 1108, thus preventing rotation of rotatable member 1108. The rotatable member 1108 may be locked into contact with rails in a variety of rotational positions by the locking member 1120. The user may rotate the lever upward to remove the auxiliary device 1100 form the weapon.
In an alternative embodiment, positioning mechanism 1114 with a transverse bar may be removed and replaced with a positioning mechanism 1114B with one or more post or pins. Alternatively, the pin(s) may be fixed to the housing or individually biased relative to the housing.
As noted in the Background, the distance from the front surface of the trigger guard to a transverse slot located along the lower surface of the dust cover of a pistol may differ from one weapon to the next. An asymmetrical positioning mechanism 1114A may be inserted in the housing 1104 (in place of positioning mechanism 1114) perpendicular to the longitudinal axis in either a first orientation or a second orientation (rotated 180 degrees about a vertical axis) depending on the desired distance D (see

The weapon 200 may be a handgun (as shown), a long gun, or shotgun. A set of rails 202 may be disposed in an area forward of a trigger guard 204 extending generally parallel to the longitudinal axis LA of the weapon 200. The tactical illuminator 107 may be coupled to rails 202 in a variety of different ways. For example, the tactical illuminator may utilize the spring-biased mechanism disclosed in issued U.S. Pat. No. 6,574,901, or a conventional rail or trigger guard clamping mechanism.
One or more actuators for controlling the on/off status of the light emitter 170 may extend outwardly from a second end of the tactical illuminator 107. A first actuator 110A may be spaced from a second actuator 110B (see
First and second actuators 110A, 110B may be coupled to cam members 152 to urge portions 154A of conductors 154 into electrical contact with portions 156A of electrical conductor 156. The cam members 152 may have cammed surfaces on opposing sides to provide momentary and constant-on operation and provide tactile feel to actuators 110A, 110B. The end portion 156B of electrical conductor 156 may extend through an opening 162 in second housing portion 122 to provide an electrical connection to a first battery 164 disposed in the housing 108. Electrical conductor 158 may provide an electrical connection between conductors 154 and contact 160, which in turn provide an electrical connection to a second battery 166 disposed in the housing 108.
It has been discovered that it is easier to train a peace officer if a tactical illuminator actuator(s) works the same, regardless of which hand the weapon is in.
