Embodiments of the present invention relate generally to firearms, and more particularly, to detachable mounting brackets that enable a plurality of accessories, including field stabilization systems, to be rapidly and securely attached to firearms, and in particular, long guns. Specifically, embodiments of the present invention relate to detachable mounting brackets that enable bipods and tripods to be rapidly and securely attached in tandem to long guns.
Many people have long utilized firearms to shoot projectiles of various sorts. For example, military personnel, law enforcement officers, hunters, and precision target shooters use different types of firearms (or weapons platforms) for different purposes. Commonly, people use firearms, including long guns, in conjunction with a bipod, to assist them in acquiring steadying their aim on a target and to prevent shooter fatigue in the field. There are many different types of tripods, bipods, and even monopods (“stabilizers”) appropriate to match shooting conditions and to provide helpful support and stabilization when acquiring a target. In many instances, stabilizers are mounted to a long gun and never removed.
Conventional stabilizers are typically not suited or designed for many different shooting applications and/or environments, e.g., some stabilizers may be designed for shooting from the prone position, while others are designed for shooting from the sitting, standing, or kneeling positions. It may be desirable, for example, to use a bipod when shooting from a prone position, but change to a taller tripod when shooting from a kneeling or standing position. Thus, some long gun users may wish to utilize different supports on the same firearm due to changes in the intended application, mission, or shooting environment.
Changing the support on a long gun can be a lengthy exercise and can pose equipment adjustment and tooling challenges. Installing bipods on a long gun, for example, may require tools and other special equipment and may require a gunsmith or armorer.
Some manufactures have devised various mounting bracket devices to provide a platform for mounting different shooting supports. Typically, these mounting brackets are rigidly and permanently attached to the forend of a firearm and supports can be attached or mounted to these brackets. Bipods are commonly attached to weapons using a screw-in stud. With advancing technologies these existing mounting brackets cannot accommodate supplemental or multiple supports. Because of the rigid attachments of the mounting bracket, there is no current capability to rapidly attach and detach a tandem mounting bracket to and from a weapon.
Embodiments of the present invention provide an easily attachable and detachable mounting bracket that solves the above-discussed drawbacks. A detachable mounting bracket according to some embodiments of the present invention can be quickly installed and removed in the field by an end-user with or without simple hand tools. Also, a detachable mounting bracket according to some embodiments of the present invention enables users of various weapons platforms to rapidly and securely attach various monopods, bipods, and tripods (“supports”) in tandem via a 1913 Picatinny Rail according to some embodiments. In other contemplated embodiments, the mounting bracket may be attachable to the weapon using a variety of mounting methods including, but not limited to, mounting to one or more QD (quick detachable) studs, a Rail Interface System, a Rail Accessory System, Weaver rails, and the like.
Generally described, a mounting bracket according to some embodiments of the present invention includes a main fixture coupled to side members that define a housing for encapsulating a portion of a weapon. One or more mounting adapters can be coupled to the fixture so that one or more supports can be attached to the bracket in tandem. Two side members can be adapted to be coupled together with a connection device so that the bracket is affixed to and securely attached to a weapon. Preferably, a connection device can be operated without tools enabling users to quickly attach the bracket to and remove the bracket from a weapon and/or support.
Detachable mounting bracket embodiments of the present invention can be attached to various weapons platforms using different methods. These different methods include, but are not limited to, a quick clamp method, a screw closure method, and a vertical interlock clamp. The embodiments of the present invention are discussed in more detail below with reference to the attached figures. It should be understood that the principles of the embodiments of the present invention can be utilized with many different types of firearms, guns, and weapons, including long guns.

Embodiments of the present invention provide a detachable firearm mounting bracket. The bracket can be easily attached to, and removed from, various weapons platforms, thus providing an easy to use mounting bracket for mounting monopods, bipods, tripods, and the like (collectively “supports”). The bracket also enables one or more supports to be attached to a weapon to aid a user in a wide range of environments. For example, the detachable mounting bracket device according to embodiments of the present invention enable users to rapidly attach supports to a shoulder-fired weapon (e.g., sniper rifle) so that the weapon can be used from virtually any position, e.g. prone, standing, kneeling, etc. In addition, users can quickly remove the support to adjust for a change in operational conditions using a detachable mounting bracket in accordance with the present invention.
Referring now to the figures,
As shown in
In an exemplary embodiment, the mounting bracket 100 further comprises a cam-locking lever 120 with a cross axle 125 disposed in a hole 122 in the cam-locking lever 120. A fastener, or cross bar, 130 preferably passes through the tensioning beam 135, the first side members 110, the cam-locking lever 120, and is attachable to the cross axle 125, which can be threaded. The cross bar 130 can be an Allen bolt, Torx bolt, threaded rod, or similar, although other fastening methods are contemplated.
The mounting bracket 100 preferably additionally comprises a plurality of connectors 145. The connectors 145 preferably connect the second side members 115 to the first side members 110 and the tensioning beam 135. The connectors 145 can be disposed in grooves or channels 150 disposed in the main fixture 105. The connectors 145 preferably provide axial alignment between the first side members 110 and the second side members 115. In some embodiments, the second side members 115 can further comprise a tab, or other means, to slideably engage the grooves 150. The tabs can provide additional axial alignment for the second side members 115. The connectors 145 can transmit the tension provided by the cross bar 130 via the tensioning beam 135 to the second side members 115. Finally, the connectors 145, in concert with cross bar 130, serve to locate the mounting bracket 100 longitudinally on the Picatinny rail of the weapon.
The cam-locking lever 120 preferably has a first position and a second position. In the first, or open, position the cam-locking lever 120 can be substantially perpendicular to the first side members 110 and in-line with the cross bar 130. In the first position, tension can be substantially removed from the tensioning beam 135 and thus, the second side members 115. This can allow the user to place the mounting bracket 100 into position on a Picatinny rail of the weapon.
In the second, or closed, position the cam-locking lever 120 can be substantially parallel to the first side members 110 and perpendicular to the cross bar 130. In this position, the camming action of the cam-locking lever 120 creates tension on the cross bar 130, and thus on the tensioning beam 135. The tensioning beam 135, in turn, exerts an inward force on the second side members 115 via the connectors 145. This can allow the user to position and secure the mounting bracket 100 in a desired location on the Picatinny rail of a weapon quickly and securely.
The mounting bracket 100 can be manufactured with various materials. For example, the mounting bracket 100 can be manufactured from a lightweight, high-tensile-strength aluminum. Alternative materials such as, for example and not limitation, titanium, steel, and polymer resin plastic may also be utilized. In addition, one or more materials can be used to manufacture the mounting bracket 100. Different materials can be used to provide a weight savings, increase mounting bracket 100 strength, and/or to vary mounting bracket 100 costs. In addition, the mounting bracket 100 can have an anodized or hard-anodized finish. In some embodiments, the connectors 145, cross bar 130, cam-locking lever 120 and/or cross axle 125 may be replaced by standard machine bolts and nuts. This can reduce cost, though some functionality may be lost (e.g., toolless removal).
In the field, it may be desirable for a user to be able to quickly transition from a prone to a standing shooting position. This, in turn, can require the user to transition from a prone-style bipod to a taller tripod, preferable for shooting from the standing position. Conventionally, this would have taken a considerable amount of time. For example, a Harris bipod is commonly used for shooting from the prone or sitting position. The Harris bipod is typically mounted to a weapon using a factory installed sling stud. On the other hand, a tripod can be mounted using a commercial Manfrotto-style or other quick release adapter. While both solutions offer quick attachment/detachment of their respective supports, they require individual mounting solutions.
Therefore, in an exemplary embodiment, the mounting bracket 100 can allow the user to install a variety of supports and other accessories by simply using the correct adapter on a common bracket 100. The mounting bracket 100 can preferably comprise an adapter mounting groove 205 and a plurality of mounting holes 140. See
In an exemplary embodiment, the mounting bracket 100 can simultaneously mount a Manfrotto-type tripod and a Harris style bipod. Other types of bipods and tripods, for example, can also be mounted using appropriate adapters 210 and 215. In an alternative embodiment, the mounting bracket 100 can mount the commercial Manfrotto-type tripod and an M14 style bipod, simply by changing to the appropriate adapter 305. See
In some embodiments, it may be desirable to mount various mounting adapters in different orientations based on user preference or space requirements. Mounting a Harris-type bipod adapter 405 with the attachment lug 410 facing the user, for example, can place the controls for the bipod closer to the user. In this configuration, the user can adjust the level of the bipod, for example, more easily because the controls are facing the user and are not obscured by the mounting adapter 405. The modularity of the mounting bracket 100 enables accessory mounting adapters to be mounted to the main fixture 105 in a variety of orientations.
