Accessory Mount for a Firearm
A firearm accessory mount may include multiple rails, each configured to mechanically couple one or more firearm accessories. Each rail may further have first and second electrically powered rail terminals for providing power to the firearm accessories when coupled to the rails. A switch may be associated with each rail that is selectively engageable to electrically couple or decouple power to that rail. Accordingly, each rail may be selectively powered to control operation of any firearm accessory mounted thereto.
The present disclosure relates to firearm accessories, and more particularly to methods and apparatus for mounting accessories onto firearms.
BACKGROUND OF THE DISCLOSUREVarious types of firearms are known use in military and/or recreational use. Certain types of firearms, such as rifles, have elongated barrels. A variety of firearm accessories have been developed that may be attached to the barrel of a firearm to assist with the primary operation of the firearm or with a secondary or auxiliary operation associated with the firearm. These accessories may perform functions according to the needs of the firearm user and the demands of the use environment. For example, accessories may provide lighting (such as a flashlight), enhanced visual capabilities (such as a night vision scope), image recording (such as a camera), or other functions.
Firearm accessories are typically secured to the firearm barrel using an accessories mount that surrounds all or a portion of the firearm barrel. Conventional firearm accessory mounts typically include means for mechanical attachment to the firearm barrel and a mounting structure, such as a rail, configured to mechanically engage the accessory. Because these mounts merely provide mechanical support, firearm accessories requiring electrical power for operation must typically include their own power source, such as a battery. This not only increases the weight of the accessory, but also may require the user to carry spare batteries specific to the accessory. When multiple accessories are used with a firearm, the user may need to carry multiple different types of spare batteries.
Additionally, some accessories may include a switch to control operation of the accessory. These switches often include extensions that place a user-engageable portion of the switch in a location more convenient to the user during operation of the firearm. These switch extensions add to cost and complexity, and may be easily become entangled with the surrounding environment, thereby leading to safety concerns.
SUMMARY OF THE DESCRIPTIONIn accordance with one aspect of the disclosure, a firearm accessory mount is configured for use with a firearm barrel and a firearm accessory having a first accessory power contact and a second accessory power contact. The firearm accessory mount includes a base configured to mechanically engage the firearm barrel and a first rail coupled to the base and configured to mechanically engage the firearm accessory. A first electrically powered rail terminal is coupled to the first rail and positioned to engage the first accessory power contact of the firearm accessory when the firearm accessory is mounted to the first rail. A second electrically powered rail terminal is also coupled to the first rail and positioned to engage the second accessory power contact of the firearm accessory when the firearm accessory is mounted to the first rail.
In another aspect of the disclosure that may be combined with any of these aspects, a firearm accessory mount is configured for use with a firearm barrel and a firearm accessory having a first accessory power contact and a second accessory power contact. The firearm accessory mount includes a base including an inner wall configured to mechanically engage the firearm barrel. A first rail is coupled to the base and configured to mechanically engage the firearm accessory, the first rail having a length extending along a longitudinal axis and including a head having first and second projections extending laterally in substantially opposite directions along substantially the length of the first rail, a first groove formed in the head, and a second groove formed in the head. A first rail terminal formed of an electrically conductive material is disposed in the first groove and positioned to engage the first accessory power contact of the firearm accessory, while a second rail terminal formed of an electrically conductive material is disposed in the second groove and positioned to engage the second accessory power contact of the firearm accessory. A power source is removably coupled to the base and electrically communicates with the first and second rail terminals of the first rail.
In another aspect of the disclosure that may be combined with any of these aspects, a firearm accessory mount is configured for use with a firearm barrel and a firearm accessory having a first accessory power contact and a second accessory power contact.

DETAILED DESCRIPTIONVarious embodiments of a firearm accessory mount are disclosed herein. The firearm accessory mount may include a rail having first and second electrically powered terminals positioned to engage contacts provided on one or more firearm accessories. The firearm accessory mount may further include a power source, such as a removable battery pack, that electrically communicates with the rail terminals. Accordingly, the firearm accessory mount not only mechanically secures the accessory to the firearm, but also provides power for operating the accessory. As a result, the user need only carry one type of battery to power all accessories, making the firearm accessory mount more convenient to use and reducing the number and/or types of batteries that he or she must carry. In some embodiments, the firearm accessory mount includes multiple rails and a switch for each rail to selectively control power to the rails and, in turn, operation of the attached accessories.
Referring to
The firearm accessory mount 20 may be attached to the barrel 26 of the firearm 22. Referring to
As best shown in
The first rail assembly 40 may include a first rail 50 coupled to the base for mechanically securing an accessory 100 (
The second, third, and fourth rail assemblies 42, 44, 46 may have configurations similar to that of the first rail assembly 40. Accordingly, the second rail assembly 42 may have a second rail 62 including a pedestal 63 and a head 64. Similarly, the third rail assembly 44 may have a third rail 65 with a pedestal 66 and a head 67. Still further, the fourth rail assembly 46 may have a fourth rail 68 including a pedestal 69 and a head 70. Each of the second, third, and fourth rails 62, 65, 68 may have a profile substantially identical to that of the first rail 50, such as a Picatinny, Weaver, or other standard or custom rail profile. Consequently, each of the second, third, and fourth rails 62, 65, 68 may also receive and secure the accessory 100.
Each of the rail assemblies 40, 42, 44, 46 further may provide electrical power to operate the accessory 100. The first rail assembly 40, for example, may include electrically powered, first and second rail terminals 72, 74 to communicate electricity to the accessory 100. The first and second rail terminals 72, 74 may be formed of an electrically conductive material, such as brass, copper, steel, aluminum, conductive elastomer, conductive plastic, conductive para-aramid synthetic fiber, conductive rubber, and conductive fabric. Additionally or alternatively, the rail terminals may be configured to conduct electricity via induction.
As best shown in
The first and second rail terminals 72, 74 may be biased outwardly to ensure contact with the first and second accessory power contacts 104, 106, respectively. For example, a first resilient member 80 may be disposed between the first groove 76 and the first rail terminal 72 to bias the first rail terminal 72 outwardly. Similarly, a second resilient member 82 may be disposed between the second groove 78 and the second rail terminal 74 to bias the second rail terminal 74 outwardly. The first and second grooves 76, 78 are located so that the first and second rail terminals 72, 74 are positioned to respectively engage the first and second accessory power contacts 104, 106. The first and second resilient members 80, 82 outwardly bias the first and second rail terminals 72, 74 to more reliably ensure that the first and second rail terminals 72, 74 make sufficient contact with the first and second accessory power contacts 104, 106 to communicate electricity to the accessory 100.
The second, third, and fourth rail assemblies 42, 44, 46 may be configured similar to the first rail assembly 40 to provide electrical power to the accessory 100. Accordingly, the second rail 62 of the second rail assembly 42 may have first and second rail terminals 84, 86, the third rail 65 of the third rail assembly 44 may have first and second rail terminals 88, 90, and the fourth rail 68 of the fourth rail assembly 46 may have first and second rail terminals 92, 94 (
In some embodiments, the firearm accessory mount 20 may include a power source that electrically communicates with each pair of rail terminals, thereby to electrically power each rail. While any power source, including a power source provided separate from the firearm accessory mount 20, may be used to power the pairs of rail terminals, certain benefits may be achieved by providing the power source integrally with the base 36. In the illustrated embodiment, the power source may be provided as a battery pack 120 (
The battery pack 120 may be detachably coupled to the base 36 to permit removal for recharging and/or replacement by a spare battery pack. To accommodate a removable battery, the base 36 may include a socket 134 configured to slidably receive at least the contact end 124 of the battery housing 122. To reduce wear caused by sliding the battery pack 120 into and out of the socket 134, the battery housing 122 may be formed of a material that is the same, or has substantially the same properties, as the material used to form the base 36.
First and second socket terminals 136, 138 are disposed in the socket 134 and formed of an electrically conductive material. The first socket terminal 136 electrically communicates with each of the first rail terminals 72, 84, 88, 92, such as by first internal wire 140, while the second socket power terminal 138 electrically communicates with the second rail terminals 74, 86, 90, 94, such as by second internal wire 142. Where the base 36 formed by the first and second base halves 36a, 36b, first and second base contacts 144, 146 may be provided to electrically couple segments of the first and second internal wires 140, 142. The first and second socket terminals 136, 138 are positioned to respectively engage the first and second battery power contacts 130, 132 when the contact end 124 of the battery housing 122 is inserted into the socket 134, thereby to communicate electricity from the battery pack 120 to the first and second rail terminals 72, 74, 84, 86, 88, 90, 92, 94.
The battery pack 120 may be rechargeable to permit repeated use. A battery recharging device (not shown) may be configured to engage the first and second battery power contacts 130, 132, thereby to communicate electricity and recharge the power storage cell 128. Alternatively, the battery pack 120 may include a DC jack (not shown) electrically communicating with the power storage cell 128 that is engageable by a wall charger, a solar charger, a portable power pack, a vehicle charger, or other type of battery charger.
The battery pack 120 may further include protection against shorting when exposed to liquid. In the exemplary embodiment, the battery pack 120 may include a circuit protection chip that performs one or more of the following functions: shuts the battery off when a short is detected; protects the battery against overcharging; prevents complete discharge of the battery; maintains a constant charge and discharge of the battery; and protects the battery against power spikes.
The first and second rail terminals of each pair of terminals may be positioned relative to one another to permit operation of the firearm accessory only when in a proper orientation. Certain firearm accessories, such as laser targeting devices, targeting scopes, and night vision scopes, may have a forward end that must be oriented away from the firearm operator. Additionally, the first accessory power contact 104 may have a first polarity, such as a positive polarity, and the second accessory power contact 106 may have a second polarity, such as a negative polarity. The first battery power contact 130 electrically coupled to the first rail terminals 72, 84, 88, 92 may be connected to the positive terminal of the battery pack 120, so that the first rail terminals 72, 84, 88, 92 all have a positive polarity. The second battery power contact 132 electrically coupled to the second rail terminals 74, 86, 90, 94 may be connected to the negative terminal of the battery pack 120, so that the second rail terminals 74, 86, 90, 94 all have a negative polarity. Each first rail terminal 72, 84, 88, 92 may be positioned relative to its respective second rail terminal 74, 86, 90, 94 such that the accessory 100 will operate only when it is attached in the proper orientation. The relative positions of first and second rail terminals may be consistent for each rail 50, 62, 65, 68 so that the accessory 100 will be properly oriented forwardly regardless of which rail it is mounted on.
An alternative embodiment of a firearm accessory mount 200 is illustrated at
Referring to
A first rail terminal 272 is disposed in the first channel 306, while a second rail terminal 274 is disposed in the second channel 308. The first and second rail terminals 272, 274 are formed of an electrically conductive material to provide power to the firearm accessory 100. More specifically, the first and second rail terminals 272, 274 are oriented upwardly and away from the base, thereby permitting access from an area above the first rail 250. This is different from the previous embodiments, in which the rail terminals were oriented downwardly toward a base of the rail. The firearm accessory 100 may have first and second power contacts 104, 106 configured and located to contact the first and second rail terminals 272, 274 when the accessory is mechanically secured to the first rail 250.
The second, third, and fourth rail assemblies 242, 244, 246 may be configured similarly to the first rail assembly 240. Accordingly, as best shown with reference to
The firearm accessory mount 200 provides additional options for providing electrical power to the rail terminals. For example, the firearm accessory mount may include the self-contained battery pack 120 (
The firearm accessory mount 200 further may be configured to permit selective powering of each rail assembly. More specifically, each rail assembly may include a switch that is operable between a closed state, in which the power source is electrically coupled to a rail terminal, and an open state, in which the power source is electrically decoupled from the rail terminal. As best shown in
Firearm accessory mount embodiments are described above that provide electrically powered rail terminals to power accessories. The rail terminals are positioned to engage contacts provided on the firearm accessory when the accessory is mounted on one of the rails, so that each accessory is automatically powered when it is attached to a rail. As a result, the firearm accessory mounts not only mechanically secure the accessory to the firearm, but also communicate electricity to power the accessory. The power source used to deliver electricity to the rail terminals may be integrally provided with the firearm accessory mount. In certain embodiments, the power source is provided as a detachable, rechargeable battery pack. As a result, the user need carry only a single type of battery, and fewer total spare batteries, to power all of the firearm accessories. Additionally, the rail terminals are sufficiently long to simultaneously or individually power multiple connected devices. In still further embodiments, switches may be provided to selectively power each pair of rail terminals, thereby reducing the need for each accessory to provide its own switching system.
While only certain embodiments have been set forth, alternatives and modifications will be apparent from the above description to those skilled in the art. These and other alternatives are considered equivalents and within the spirit and scope of this disclosure and the appended claims.
