This application claims priority to Provisional U.S. Application Ser. No. 62/773,854, filed on Nov. 30, 2018, which is hereby incorporated by reference in its entirety.

BACKGROUND

A tripod-type support is often used to stabilize, support the weight of, and elevate various types of equipment that are mounted to a mounting head. Example equipment typically mounted to a tripod includes support interfaces (for example, a length of a Picatinny (MIL-STD-1913), Weaver, or other type of accessory rail; a HOG SADDLE/PIG SADDLE vice-type mount; or other support interface), optical devices (for example, spotting scopes, telescopes, and cameras) and weapon systems (for example, rifles and grenade launchers). In a situation where there is a single available tripod and multiple pieces of equipment, quickly transitioning from one type of equipment to another can be time-consuming and cumbersome.

SUMMARY

The present disclosure describes a multi-use block (MUB) quick-transitioning (QT) equipment support interface.
In an implementation, a multi-use block (MUB) quick-transitioning (QT) handguard body includes an upper surface of the body configured to engage with and to secure equipment to the body. A channel is configured through the body for maintaining a firearm barrel. A bottom surface is configured with a support mounting interface. A rear surface of the body is configured for attachment to a firearm handguard mounting system. The body is configured with one or more accessory attachment points.
The subject matter described in this specification can be implemented in particular implementations so as to realize one or more of the following advantages. First, in a situation where there is a single available tripod and multiple pieces of equipment (for example, optical devices or firearms), the MUB permits quick transition of the equipment used with the tripod. Second, when using a MUB with a support interface (for example, a HOG SADDLE), a user can quickly transition from one type of equipment to another without having to remove the HOG SADDLE from the tripod. For example, a MUB with an attached spotting scope can be secured in the HOG SADDLE, and when the user is ready to transition to a firearm, the MUB/spotting scope combination can simply be removed from the HOG Saddle and the firearm can be placed into the HOG SADDLE. In some implementations, a user can also leave the MUB installed in the support interface and quickly detach and replace (for example, by using quick-detach (QD) accessory rail mounts secured to the MUB) one type of equipment attached to the MUB with another. Third, the MUB can be used as a boresight tool to permit rough orientation of the MUB/attached equipment in relation to a desired target. For example, a user can orient the MUB by looking at the desired target through a central circular channel defined by the body of the MUB to provide a rough boresight to align the MUB/attached equipment toward the desired target. Fourth, the MUB can be used to mount auxiliary optical or other equipment for use by a user. For example, an optical sighting assembly (such as a low-magnification monocular or a micro-type red-dot sight) or a laser range finder could be mounted in the central circular channel. Fifth, the MUB can be configured to include one or more bubble-type levels to permit a user to level the MUB (and by extension—any attached equipment) on one or more axes when mounted to a tripod. Sixth, in some implementations, the MUB can be configured for use as a handguard for different firearm platforms. Other advantages will be apparent to those of ordinary skill in the art.
The details of one or more implementations of the subject matter of this specification are set forth in the accompanying drawings and the description. Other features, aspects, and advantages of the subject matter will become apparent from the description, the drawings, and the claims.

DETAILED DESCRIPTION

The following detailed description describes a multi-use block (MUB) quick-transitioning (QT) equipment support interface, and is presented to enable any person skilled in the art to make and use the disclosed subject matter in the context of one or more particular implementations. Various modifications, alterations, and permutations of the disclosed implementations can be made and will be readily apparent to those skilled in the art, and the general principles defined may be applied to other implementations and applications, without departing from scope of the disclosure. The present disclosure is not intended to be limited to the described or illustrated implementations, but to be accorded the widest scope consistent with the described principles and features.
A tripod-type support (hereinafter, “tripod”) is often used to stabilize, support the weight of, and elevate various types of equipment that are mounted to a mounting head. Example equipment typically mounted to a tripod includes support interfaces (for example, a length of a Picatinny (MIL-STD-1913), Weaver, or other type of accessory rail; a HOG SADDLE/PIG SADDLE vice-type mount; or other support interface), optical devices (for example, spotting scopes, telescopes, and cameras) and weapon systems (for example, rifles and grenade launchers).
In a situation where there is a single available tripod and multiple pieces of equipment, quickly transitioning from one type of equipment to another can be time-consuming and cumbersome. For example, if a HOG SADDLE is used with a tripod to secure a spotting scope, there is not a convenient way to transition from using the same HOG SADDLE with a firearm. In this situation, the HOG SADDLE must be opened to remove the spotting scope and then the firearm inserted and secured into the HOG SADDLE. In another example, the spotting scope can be attached directly to the tripod. To use the firearm, the spotting scope must be removed from the tripod so that a HOG SADDLE can be attached to the tripod for use with the firearm.
In contrast to the previously described situations, when using a MUB with a HOG SADDLE, a user can quickly transition from one type of equipment to another without having to remove the HOG SADDLE from the tripod. For example, a MUB with an attached spotting scope can be secured in the HOG SADDLE, and when the user is ready to transition to a firearm, the MUB/spotting scope combination can simply be removed from the HOG Saddle and the firearm can be placed into the HOG SADDLE. In some implementations, a user can also leave the MUB installed in the HOG SADDLE and quickly detach and replace (for example, by using quick-detach (QD) accessory rail mounts secured to the MUB) the spotting scope attached to the MUB with a firearm.
The MUB QT equipment support interface (hereinafter “MUB”) typically provides an interface between a tripod and equipment attached to the MUB. In some implementations, the MUB can be directly attached to a tripod mounting head (for example, with a thumbscrew or other type of mounting assembly) or secured with a separate support interface (for example, a HOG SADDLE). As will be appreciated by those of ordinary skill in the art, while this disclosure focuses on the use of a tripod as a support system, any appropriate support system for the described and other equipment consistent with this disclosure is considered to be within the scope of this disclosure.
The MUB is a hollow-core, substantially cuboid-shaped QT equipment interface between equipment and a tripod or a tripod/support interface combination (such as a HOG SADDLE attached to a tripod). The upper surface of the MUB body is configured to permit attachment of a multitude of mounting interfaces, brackets, systems, etc. (for example, Picatinny rail QD accessory bases configured to accept and secure a Picatinny rail attached to a piece of equipment) (hereinafter, “equipment mounting interface”). In some implementations, the MUB body is configured at its base to accept a standard mounting head thumbscrew (for example, as used on a tripod) or to readily accept attachment of a multitude of other mounting interfaces, brackets, or systems (hereinafter, “support mounting interface”). In typical implementations, the MUB is configured to leverage standard thumbscrew-type mounting configurations as a common interface, but other types of common interfaces can be used depending upon the intended use of the MUB.
In typical implementations, the MUB body can be configured to include one or more bubble-type levels to permit a user to level the MUB (and by extension—attached equipment) on one or more axes when mounted to a tripod. In this configuration, the level of attached equipment can be quickly determined.
FIG. 1A is an image 100 a illustrating a MUB mounted in a support interface, according to an implementation of the present disclosure. As illustrated, the lower portion of the MUB 102 is secured within a support interface 104 (a HOG SADDLE). The support interface 104 is attached to a tripod 106. The upper surface of the MUB 102 is engaged with an optical device 108 (a spotting scope) using Picatinny rail QD accessory bases 110 as equipment mounting interfaces.
In the illustrated configuration, the MUB 102 with attached optical device 108 can be quickly removed from the support interface 104 by releasing the vice-type action of the support interface 104, using control knob 112. Once the MUB 102 and optical device 108 are removed, a different MUB 102 with attached equipment, a weapon system, or other types of equipment can be secured by the support interface 104.
Turning to FIG. 1B, FIG. 1B is an image 100 b illustrating a weapon system mounted in the support interface 104 of FIG. 1A, according to an implementation of the present disclosure. As illustrated, weapon system 114 is secured by clamping the forearm 115 of the weapon system 114 in the support interface 104, which is mounted to tripod 106.
Returning to FIG. 1A, alternatively, the MUB 102 can be left secured in the support interface 104 and the optical device 108 removed from the MUB by releasing the Picatinny rail QD accessory bases 110. A different piece of equipment (for example, a different optical device or a weapon system) can then be attached to the secured MUB 102 using the Picatinny rail QD accessory bases 110.
FIG. 2A is an image 200 a illustrating a MUB with an attached optical device mounted directly to a tripod, according to an implementation of the present disclosure. As illustrated, the MUB 102 is directly attached to the tripod 106 (for example, using the previously-described thumbscrew-type mounting assembly). The optical device 108 is, as in FIGS. 1A and 1B, engaged with the upper surface of the MUB 102 using two Picatinny rail QD accessory bases 110 as equipment mounting interfaces.
FIG. 2B is an image 200 b illustrating a weapon system engaged to a MUB that is directly mounted to a tripod, according to an implementation of the present disclosure. As illustrated, weapon system 114 is engaged with the upper surface of the MUB 102 using Picatinny rail QD accessory bases 110 to couple to a length of a Picatinny accessory rail 202 attached to the bottom of the forearm 115 of the weapon system 114. In this configuration, no pressure is exerted on the forearm 115 of the weapon system 114 (for example, with the HOG SADDLE support interface 104 as illustrated in FIG. 1B). Using the Picatinny rail QD accessory bases 110 to attach the weapon system 114 to the MUB 102 can help to avoid damage to the weapon system 114 by eliminating the need to exert pressure on various components of the weapon system 114, maintain the security of the weapon system 114's attachment to the tripod 106 following recoil generated by a number of weapon system 114 discharges, and make removal of the weapon system 114 from the MUB 102, simple and efficient.
FIG. 3A is a top perspective view 300 a of a MUB body, according to an implementation of the present disclosure. As previously stated, the MUB body 302 is a hollow-core, substantially cuboid-shaped QT equipment interface between a piece of equipment and a tripod or a tripod/support interface combination (such as a HOG SADDLE attached to a tripod).
In some implementations, the MUB body 302 can be extruded from various materials, such as metal (for example, 6061/7075 aluminum, titanium, or steel), metal alloys (for example, Inconel), polymer, or composite (for example, carbon fiber). In other implementations, the MUB body can be injection-molded, forged, three-dimensionally printed (for example, using sintering welding), CNC machined from “bar”-type material stock, or generated/configured by other industrial methods consistent with this disclosure.
In some implementations, various manufacturing processes can be used to form the MUB body 302 where one or more components of one or more equipment mounting interfaces (for example, Picatinny rail QD accessory bases 110) or a support mounting interface (for example, refer to FIG. 14 and associated description) can be integrally formed as part of the MUB body 302. This configuration, among other things, can provide lower-cost manufacturing, reduce an overall number of parts, and provide a more stable MUB platform. For example, in a particular implementation, complete equipment mounting interfaces or support mounting interfaces can be formed as part of the MUB body 302, using a direct metal laser sintering (DMLS) or similar process.
In typical implementations, the MUB body 302 can be protected using various finishes appropriate to the material the MUB body 302 is configured of. For example, an aluminum MUB body 302 can be anodized, coated with CERAKOTE, DURACOAT, or paint, or powder coated. Similarly, a steel MUB body 302 can be phosphatized, coated with CERAKOTE, DURACOAT, or paint, or powder coated. Any finish consistent with this disclosure is considered to be within the scope of the disclosure.
The upper surface 304 of the MUB body 302 is flat, parallel or substantially parallel to a lower surface 306 (also see FIG. 3B), and configured with an elevated mounting ridge 308. In typical implementations, the upper surface 309 of the mounting ridge 308 is also parallel or substantially parallel to the lower surface 306 and the sides of the mounting ridge 308 are perpendicular to the plane formed by the upper surface 304. The elevated nature of the mounting ridge 308 is configured to engage with, and to provide lateral support to, an attached equipment mounting interface with respect to the lengthwise axis of the MUB body 302. Mounting ridge 308 is configured to permit attachment of one or more equipment mounting interfaces (not illustrated) using screws or other fasteners. For example, illustrated MUB body 302 is configured to define a plurality of holes 310 along the length of the mounting ridge 308. In typical implementation, some or all of the plurality of holes 310 are threaded to accept commonly sized machine-type screws used to secure an equipment mounting interface to the MUB body 302. As will be appreciated by those of ordinary skill in the art, the MUB body 302 and mounting ridge 308 can be configured in a multitude of ways to permit various fasteners and attachment methods to be used to secure an equipment mounting interface to the MUB body 302. These other configurations, in as much as they are consistent with this disclosure, are considered to be within the scope of this disclosure. Chosen mounting interfaces are configured to accept the shape and height of the mounting ridge 308 (for example, refer to FIG. 11) and then to be secured to the MUB body 302 with the previously mentioned fasteners or attachment methods. In some implementations, the MUB body 302 can be configured with an integral equipment mounting interface (for example, a Picatinny- or WEAVER-type rail, MAGPUL M-LOK or KEYMOD cutouts, or other interfaces) instead of an equipment mounting interface that attaches to the mounting ridge 308.
MUB body 302 also is configured to define a support mounting hole 312. Support mounting hole 312 is used to attach the MUB body 302 to a standard tripod thumbscrew-type mounting configuration (for example, a tripod-type quick-release or other mounting configuration) or to a support mounting interface leveraging the standard thumbscrew-type mounting configuration as a common interface. In typical implementations, the support mounting hole 312 can be configured with a ¼-20 UNC or ⅜-16 UNC Unified Thread Standard (UTS) threads or ⅜-16 UNC threads with a removable ¼-20 UNC thread adaptor. As will be appreciated by those of ordinary skill in the art, the MUB body 302 lower surface 306 can be configured in a multitude of ways to permit various fasteners and attachment methods to be used for attachment of the MUB body 203 to a tripod. These other configurations, in as much as they are consistent with this disclosure, are considered to be within the scope of this disclosure. For example, as illustrated in FIGS. 17 and 18A-18D, the MUB body can be configured with an integral or attached ARCA-SWISS/MANFROTTO interface.
In typical implementations, the MUB body 302 is configured to include one or more bubble-type levels to permit a user to level the MUB 102 (and by extension—any attached equipment) on one or more axes when mounted to a tripod. The MUB body 302 can be configured to define a cylindrical path 314 into which a cylindrical bubble level can be inserted and secured in place to view in a bubble level viewing slot 316. In typical implementations, the cylindrical bubble level can be secured in the cylindrical path 314 using an adhesive in the cylindrical path 314, securing plugs (for example, an epoxy-type adhesive) at each end of the cylindrical path 314, set screws, pins, or a combination of these methods. Other methods of securing the cylindrical bubble level in the cylindrical path 314, in as much as they are consistent with this disclosure, are considered to be within the scope of this disclosure. Although not illustrated, the MUB body 302 can also be configured to support bubble levels along one or more other axes (for example, perpendicular or diagonal to the illustrated cylindrical path 314) of the MUB body 302. In other implementations (not illustrated), one or more bubble levels can be attached (for example, with adhesives or screws) to the exterior of the MUB body 302.
The MUB body 302 is also configured to define a channel 318 along the lengthwise (optical) axis of the MUB body 302. In typical configurations, the channel 318 is configured through the central portion of the MUB body 302. In typical configurations, the channel 318 can be used to roughly boresight the MUB 102 with an attached piece of equipment with respect to a target. For example, a user can mount the MUB 102 with an attached weapon system 114 to a tripod 106. The user can orient the MUB 102 on the tripod 106 by sighting down the channel 318 at a distant target. The user can then switch sighting of the target to an optical device (for example, a rifle scope) associated with the weapon system 114 to engage with the target with precision. In typical configurations, the channel 318 is circular in shape. In other implementations, the channel 318 can be configured in any shape consistent with this disclosure (for example, oval, square, or rectangular).
In other implementations, the channel 318 can be used to mount auxiliary optical, or other equipment for use by a user. For example, an optical sighting assembly (such as a low-magnification monocular or a micro-type red-dot sight) or a laser range finder could be mounted in the channel 318. As will be appreciated by those of ordinary skill in the art, while not implemented, the MUB body 302 (and particularly the channel 318) can be configured (for example, with mounting structures, threaded holes, or structures to support attachment of lengths of accessory rails) to support the addition of the described optical or other equipment. In some implementations, a length of accessory rail can be configured to extend from the interior of the channel 318 and beyond the front or back plane of the MUB body 302. In some implementations, the channel 318 and one or more aspects of the MUB body 302 or other components of the MUB can be configured to act as a handguard for different firearms platforms (such as, semi-automatic, select-fire, bolt, direct gas impingement, piston, electrical, mechanically cranked, air/compressed gas-driven, spring-driven, single-shot, or other types of firearms). In other words, a firearm barrel for directing a projectile and/or other part of a firearm can be inserted into/through the channel 318 and the MUB secured to the firearm (for example, to an upper or lower receiver or mounting point on the barrel) using one or more industry standard or proprietary mounting systems (such as, a delta ring/retaining ring for an AR-15/M-16-type firearm platform, free-float handguard mounting interface integrated with a receiver assembly, or any other type of firearm handguard mounting system as understood by one of ordinary skill in the art). The MUB body 302 is extended/elongated, if necessary, to support different firearm types (for example, rifles or handguns), sizes, or barrel lengths (for example, rifle, carbine, or short-barrel designs). For additional detail with respect to this implementation, refer to FIGS. 17 and 18A-18D.
In some implementations, the MUB body 302 can be configured to permit attachment of optical or other equipment for use by a user. Although not illustrated, the exterior (for example, the sides) of the MUB body 302 can be configured (for example, with mounting structures, threaded holes, or structures to support attachment of lengths of accessory rails) to support the addition of the described optical or other equipment. In some implementations, a length of accessory rail can be configured to extend from the exterior of the MUB body 302 beyond the front or back plane of the MUB body 302.
In typical implementations, the MUB body 302 is configured to define a plurality of cutouts (for example, indicated cutouts 320) on various surfaces of the MUB body 302 (for example, along the left side, right side, and lower surface 306). The removal of material in defining the cutouts 320 helps to reduce overall weight of the MUB body 302 and permits access to interior portions of the MUB body 302. Removal of material to define the plurality of cutouts 320 also defines a plurality of support ribs (for example, indicated support ribs 322). The MUB body 302 can be configured to where support ribs 322 provide necessary strength and stiffness for the MUB body 302 to support particularly desired equipment attached to the MUB 102. As will be appreciated by those of ordinary skill in the art, the illustrated MUB body 302 reflects only one possible configuration. Other configurations consistent with this disclosure are also considered to be within the scope of this disclosure.
FIG. 3B is a bottom perspective view 300 b of the MUB body of FIG. 3A, according to an implementation of the present disclosure. View 300 b illustrates that the lower surface 306 is flat and parallel or substantially parallel to upper surface 304 (and the upper surface 309 of the elevated mounting ridge 308). Although not illustrated, in some implementations, the portion of the MUB body 302 configured with support mounting hole 312 can be configured as recessed. In this configuration, an attached support mounting interface can rest recessed or level with respect to the plane of the lower surface 306 of the MUB body 302 and permit the MUB 102 to rest level against the bottom surface of a support interface 104 (such as a HOG SADDLE).
FIG. 3C is a front view 300 c of the MUB body of FIGS. 3A and 3B with example dimensions, according to an implementation of the present disclosure. Although not illustrated, in the implementation illustrated in FIG. 3C, the MUB body 302 also measures 4.10 in. from the back and front surfaces of the MUB body 302. In other implementations, one or more of the illustrated example dimensions can vary, depending on the desired configuration and use of the MUB 102, equipment to use with the MUB 102, support interface, and other considerations consistent with this disclosure.
FIG. 4 is a left side view 400 of the MUB body of FIGS. 3A-3C, according to an implementation of the present disclosure. Note that the right side view (opposite of the left side view 400) of the MUB body 302 is a mirror image of the left side view 400 and is not illustrated.
FIG. 5 is a back view 500 of the MUB body of FIGS. 3A-3C and 4, according to an implementation of the present disclosure. As illustrated the MUB body 302 has a back surface 501. In typical implementations, the plane formed by the back surface 501 is parallel or at least substantially parallel to the plane formed by the front surface of the MUB body 302 and perpendicular or substantially perpendicular to the planes defined by the upper surface 304 and the lower surface 306. In other implementations, the plane of the back surface 501 can be angled with respect to the typical perpendicular relationship with the planes defined by either the upper surface 304 or the lower surface 306.
The MUB body 302 also has a left side 502 and a right side 504. In some implementations, the bottom corners 506 and 508 of the left side 502 and the right side 504, respectively, are relieved and somewhat rounded. This configuration permits weight saving by removing material from the MUB body 302 and also permits easier insertion of the MUB body 302 into a support interface 104 (for example, a HOG SADDLE). Similarly, the upper portions 510 and 512 of the left side 502 and the right side 504, respectively, are also relieved and angled inward toward the central vertical axis running through the upper surface 304 and the lower surface 306. This configuration also permits weight saving by removing material from the MUB body 302 and making the MUB 102 easier to hold in a user's hand.
FIG. 6 is a front view 600 of the MUB body of FIGS. 3A-3C and 4-5, according to an implementation of the present disclosure. As illustrated the MUB body 302 has a front surface 602. In typical implementations, the plane formed by the front surface 602 is parallel or substantially parallel to the plane formed by the back surface 501 of the MUB body 302 and perpendicular to the planes defined by the upper surface 304 and the lower surface 306. In other implementations, the plane of the front surface 602 can be angled with respect to the typical perpendicular relationship with the planes defined by either the upper surface 304 or the lower surface 306.
FIG. 7 is a top view 700 of the MUB body of FIGS. 3A-3C and 4-6, according to an implementation of the present disclosure. From the top view 700, the angling in of the left side 502 and the right side 504 due to removal of the material from the MUB body 302 at the upper portions 510 and 512 of the left side 502 and right side 504, respectively, is apparent.
FIG. 8 is a bottom view 800 of the MUB body of FIGS. 3A-3C and 4-7, according to an implementation of the present disclosure. From the bottom view 800, the angling in of the left side 502 and the right side 504 due to removal of the material from the MUB body 302 at the bottom corners 506 and 508 of the left side 502 and right side 504, respectively, is apparent.
FIG. 9 is a left side view 900 of an example configured MUB, according to an implementation of the present disclosure. Note that the right side view (opposite of the left side view 900) of the example MUB is a mirror image of the left side view 900 and is not illustrated. As illustrated, the MUB body 902 (for example, a MUB body 302) is finished in a CERAKOTE finish of a flat dark earth (FDE) color. A support screw 904 has been threaded into a support mounting hole (for example, a support mounting hole 312) from the lower surface 905 (for example, lower surface 306) of the MUB body 902. Two equipment mounting interfaces 906 (for example, Picatinny rail QD accessory bases 110) have been secured to the MUB body 902 using a mounting ridge 908 (for example, a mounting ridge 308). The end of an installed horizontal-axis bubble level 910 is also visible at the end of a configured cylindrical path 912 (for example, a cylindrical path 314).
FIG. 10 is a back view 1000 of the example configured MUB of FIG. 9, according to an implementation of the present disclosure. As illustrated, the installed horizontal-axis bubble level 910 can be seen from the back surface 1002 (for example, a back surface 501) of the MUB body 902 through a bubble level viewing slot 1004 (for example, a bubble level viewing slot 316). The engagement between the mounting ridge 908 and an equipment mounting interface 906 is also visible.
FIG. 11 is a front view 1100 of the example configured MUB of FIGS. 9-10, according to an implementation of the present disclosure. From the front surface 1102 (for example, a front surface 602) of the MUB body 902, the engagement between the mounting ridge 908 and an equipment mounting interface 906 is visible.
FIG. 12 is a top view 1200 of the example configured MUB of FIGS. 9-11, according to an implementation of the present disclosure. As illustrated, each equipment mounting interface 906 is secured to the mounting ridge 908 of the MUB body 902 using two screws 1202.
FIG. 13 is a bottom view 1300 of the example configured MUB of FIGS. 9-12, according to an implementation of the present disclosure. Support mounting hole 1302 (for example, a support mounting hole 312) on lower surface 905 (for example, the lower surface 306) of the MUB body 902 can carry a support screw 904 or other screw (not illustrated). Additionally, the ends of installed screws 1202 securing each equipment mounting interface 906 to the mounting ridge 908 are visible from the interior of the MUB body 902.
FIG. 14 is a bottom view 1400 of the example configured MUB of FIGS. 9-13, according to an implementation of the present disclosure. As illustrated, an alternative support mounting interface 1402 (for example, one portion of a two-piece sliding bracket-type support mounting interface) has been secured to the lower surface 905 of the MUB body 902. In this configuration, the alternative support mounting interface 1402 can be coupled with a corresponding second piece (not illustrated) of the example sliding bracket-type support mounting interface that is secured to the mounting head of a tripod. When interfaced together, the completed bracket-type support mounting interface can secure the MUB body 902 to the tripod. Support screw 1404 is used to secure the alternative support mounting interface 1402 to the MUB body 902.
FIGS. 15A and 15B are side views 1500 a and 1500 b, respectively, of an alternate MUB configuration, according to an implementation of the present disclosure. Clamp Assembly 1502 is an equipment mounting interface used to attach an accessory rail (such as, a Picatinny rail) to a MUB. As illustrated, in FIG. 15A, Clamp Assembly 1502 includes Throw Levers 1504 shown in a closed configuration. In some implementations, the Throw Levers 1504 are configured for placement on and to operate on the left side of the MUB and are adjustable (using adjustment screws) to permit a solid and precise fit to an accessory rail. In the illustrated MUB of FIG. 15B, Clamp Assembly Tension Adjustment Screws 1506 of the Clamp Assembly 1502 are configured for placement on, and to operate on the right side of the MUB body. The Clamp Assembly Tension Adjustment Screws 1506 are also used to attach the Throw Levers 1504 to the MUB (for example, using a tension clamp bar threaded on one end to engage with the Clamp Assembly Tension Adjustment Screws 1506). In some implementations, the Clamp Assembly Tension Adjustment Screws 1506 can be turned/adjusted using a screwdriver, such as a Standard or Phillips-type screwdriver.
The alternative MUB configuration also has integrally machined brackets 1508 (here illustrated with two separate brackets) that can be interfaced with tripod-type support systems, such as those by MANFROTTO or REALLY RIGHT STUFF (RRS). Other implementations can include integrally machined brackets of any type of configuration to interface with any support system, clamp, or device. In some implementations (not illustrated) brackets similar to the integrally machined brackets 1508 can be configured to be attached to the bottom of the MUB body (for example, with screws) to permit the MUB to be more flexibly configured for different uses.
Clamp Bar 1510 is biased toward the other side of the MUB body by rotation of the Throw Levers 1504 and is configured to engage with an accessory base (for example, an accessory base 110) and secure it to the MUB body. Clamp Bar 1510 is typically configured as a single piece for strength and to engage with as much of the accessory rail as possible.
FIG. 15C is a side view 1500 c of the alternate MUB configuration of FIGS. 15A and 15B, according to an implementation of the present disclosure. As illustrated, Throw Levers 1504 are shown in an open configuration, which releases tension on the Clamp Bar 1510. As illustrated, integrally machined brackets 1508 can be machined in a manner to lighten the weight and thickness of the integrally machined brackets 1508 and the overall MUB.
FIG. 15D is a top view 1500 d of the alternate MUB configuration of FIGS. 15A-15C, according to an implementation of the present disclosure. As illustrated, Throw Levers 1504 are shown in an open configuration, which releases tension on the Clamp Bar 1510. Tension Clamp Bar 1512 is attached to Throw Lever 1504 and provides a tensioning adjustment increasing/decreasing the distance between the right (fixed) and left (adjustable Clamp Bar 1510) sides of the Clamp Assembly 1502. The right side of Clamp Assembly 1502 is configured to engage with an accessory rail and secure it to the MUB body in conjunction with the Clamp Bar 1510.
FIG. 15E is a back view 1500 e of the alternate MUB configuration of FIGS. 15A-15D, according to an implementation of the present disclosure. As illustrated, Throw Levers 1504 are shown in an open configuration, which releases tension on the Clamp Bar 1510. In some configurations, spring 1514 is positioned on Tension Clamp Bar 1512 to provide a spring bias away from the right side of the Clamp Assembly 1502.
FIG. 16A is a top view 1600 a of a Wing Interface 1602 configured to be attached to the MUB, according to an implementation of the present disclosure. Wing Interface 1602 is configured to attach to the MUB body with the Clamp Assembly 1502 (for example, with a Picatinny rail) and extends horizontal coverage of the MUB to permit multiple devices (for example, laser range finder, camera, optical scope, binoculars, spotting scope, video camera, or telephone) to be attached to the MUB simultaneously and extending horizontally away from the top of the MUB. The illustrated Wing Interface 1602 includes an Adjustment Slot 1604 and Attachment Screw 1606 (for example, ¼ 20 camera thumb-type or other screws). In some implementations, the Adjustment Slot 1604 is configured to be 2 in. in length so that attached devices can be secured at various positions along the surface of the Wing Interface 1602. In some implementations, the Wing Interface 1602 is machined from 6061 aluminum or other materials. The illustrated implementation of the Wing Interface 1602 is symmetrical on either side, but other implementations can have differently sized or shaped side “wings”, recessed circle configurations, or screws, depending on particular operational needs.
The Wing Interface 1602 is configured with recessed circles 1608 (for example, twenty-eight, ½ in. diameter recessed circles) on each end of the upper surface 1610 of the Wing Interface 1602. Although illustrated in parallel rows, the recessed circles 1608 can be configured to be in other configurations/orientations surrounding the adjustment slot 1604. Each recessed circle 1608 can be used to secure (for example, using an adhesive or screw) pucks 1612 (for example, rubber or neoprene). The pucks 1612 provide stability and greater friction between the upper surface 1610 of the Wing Interface 1602 and a secured device. In some implementations, instead of (or in addition to) the recessed circles 1608, the Wing Interface 1602 can be configured with other types of equipment mounting interfaces (for example, MAGPUL M-LOK or KEYMOD cutouts). In some implementations, the adjustment slot 1604 can be omitted on one or both sides of the Wing Interface 1602.
Wing Interface 1602 also includes an Accessory Rail 1614 (for example, an accessory rail 202), such as, a Picatinny rail. The Accessory Rail 1614 is configured engage with a MUB Clamp Assembly (for example, a Clamp Assembly 1502).
FIG. 16B is a bottom view 1600 b of the Wing Interface 1602 of FIG. 16A, according to an implementation of the present disclosure. As illustrated, the Accessory Rail 1614 is attached to the Wing Interface 1602 using an Attachment Screw 1616. In the illustrated implementation, the Accessory Rail 1614 is attached to the Wing Interface 1602 using a Groove 1618 machined into the bottom of the body of the Wing Interface 1602. In the illustrated implementation, the underside of the body of the Wing Interface 1602 is machined in a manner to lighten weight and thickness of the body. In some implementations, the Wing Interface 1602 can be configured to directly attach (that is, omitting the Accessory Rail 1614 Attachment Screw 1616) to a MUB body as previously described or to an elongated MUB body as described in FIGS. 17 and 18A-18D. For example, the Wing Interface 1602 can be configured to interface directly with the previously described mounting ridge 308 (that is, the Groove 1618 can be configured accordingly) or to support one or more Picatinny or other interfaces. In some implementations, an interface (such as, a Picatinny quick-detach clamp) could be attached to Groove 1618 (for example, by screws or other fasteners) to clamp to a Picatinny rail configured as part of the upper surface of the MUB body or the elongated MUB body. In some implementations, the Wing Interface 1602 can omit the Groove 1618 and the interface can be attached to the underside of the Wing Interface 1602 using screws or other fasteners. In some implementations, the bottom surface of the Wing Interface can be configured with an ARCA-SWISS or MANFROTTO interface. In some implementations, the Wing Interface 1602 can be configured with interfaces (in some cases, omitting the Accessory Rail 1614 and Attachment Screw 1616) that include MAGPUL M-LOK, KEYMOD, Picatinny, WEAVER, or other interfaces to permit mounting the Wing Interface 1602 to a MUB body or an elongated MUB body with an appropriate mounting apparatus, as will be appreciated by those of ordinary skill in the art.
FIG. 16C is a side view 1600 c of the Wing Interface 1602 of FIGS. 16A and 16B, according to an implementation of the present disclosure. The illustrated implementation of the Wing Interface 1602 is symmetrical on either side, but other implementations can have differently sized or shaped side “wings” depending on particular operational needs.
FIG. 17 is left side view 1700 of a MUB configured for use as a firearm platform handguard, according to an implementation of the present disclosure. As will be understood by one of ordinary skill in the art, the implementations of FIGS. 17 and 18A-18D can include one or more features or be configured in a manner as described in other portions of this disclosure. An elongated MUB body 1702 is shown configured as a firearm handguard surrounding a firearm barrel 1704 (with attached muzzle device). Length of the elongated body 1702 can depend on, for example, length of the barrel, gas system desired (such as, carbine or mid-length for direct impingement gas systems), piston length, or other factor(s) consistent with this disclosure. In some implementations, the elongated MUB body 1702 can be configured as a “free-float” type handguard (that is, not making contact with a firearm barrel).
The elongated MUB body 1702 is illustrated as configured with two accessory attachment points. Illustrated are MAGPUL M-LOK-type attachment points 1706 and flush cups (that is, QD attachment points) 1708 (also, although not illustrated, corresponding attachment points 1706/1708 are present on the opposite side of the illustrated MUB handguard). In other implementations, one or both of the described attachment points 1706/1708 can be configured into other surfaces of the MUB handguard based on user or other requirements. In addition, other implementations can include other types of attachment point configurations, for example, WEAVER, KEYMOD, Picatinny rail or other standard/proprietary-type attachment points.
The elongated MUB body 1702 is also illustrated as configured an integrated Picatinny accessory rail 1710 machined into the upper surface of the elongated MUB body 1702. As will be appreciated by those of ordinary skill in the art, the illustrated implementation is only one possible implementation of configuration and attachment points. In other implementations, the upper (or other) surface(s) could instead be configured with other types of equipment mounting interfaces (for example, 906 in FIG. 9 or any other mounting system consistent with this disclosure). In some implementations, the MUB handguard can have integrally configured attachment points or attachment points can be attached to the MUB handguard (for example, using screws, clips, bolts, welding, adhesive, or other attachment method).
A MUB handguard implementation retains versatility of other MUB implementations by utilizing, for example, an ARCA-SWISS/MANFROTTO (or other) interface design on the bottom surface. For example, part of the lower surface 1712 can be configured with an ARCA-SWISS interface, while another portion of the lower surface 1712 is configured with a MANFROTTO interface 1716. In some implementations, the ARCA-SWISS 1714/MANFROTTO 1716 interfaces are integrated (that is, machined) into the bottom of the elongated MUB body 1702. In other implementations, the elongated MUB body 1702 can be configured in such a manner to couple with separate ARCA-SWISS/MANFROTTO (or other) interfaces. This particular illustrated an ARCA-SWISS/MANFROTTO interface configuration permits a user to utilize substantially the entire bottom surface 1712 of the MUB handguard for forward and backward adjustment of position. In addition, a user can utilize any tripod, bipod, aircraft mount, or any mounting system that interfaces with previously described MUB implementations.
FIG. 18A is a perspective view 1800 a of a MUB configured for use as a firearm platform handguard, according to an implementation of the present disclosure. Note that in the implementation illustrated in FIG. 18A, the illustrated QD attachment points 1708 vary slightly in configuration from those illustrated in FIG. 17 and FIGS. 18B-18D (that is, raised from the surface of the elongated MUB body 1702). As will be appreciated by those of ordinary skill in the art, any of the described attachment points or other illustrated interfaces may vary (even on a single MUB) depending, for example, on manufacturer, specifications, materials used, particular purpose, or other criteria, but still be used according to particular specifications and purposes of the particular attachment points or other illustrated interfaces. Although not illustrated, in some implementations, rear surface 1802 and front surface 1804 can be configured in such a manner to permit interfacing with one or more firearm handguard mounting systems, as previously discussed.
FIG. 18B is a rear perspective view 1800 b of the MUB of FIG. 18A configured for use as a firearm platform handguard, according to an implementation of the present disclosure.
FIG. 18C is a bottom perspective view 1800 c of the MUB of FIG. 18A configured for use as a firearm platform handguard, according to an implementation of the present disclosure. In some implementations, to reduce overall weight and/or to permit airflow to ensure firearm barrel cooling, portions of the MUB can be configured without material. For example, and as illustrated in FIG. 18C (also refer to FIG. 18A), the elongated MUB body 1702 has material removed in the area of the ARC-SWISS interface 1714 to define openings into the elongated MUB body 1702. Strengthening ribs 1808 can also be defined to retain rigidity for the elongated MUB body 1702. By comparison, FIG. 18B is not illustrated with material removed in all the locations as illustrated in FIG. 18C. A possible configuration of FIG. 18B could also include removal of some of the material as illustrated in FIG. 18C to reduce overall weight, but not enough to define openings into the elongated MUB body 1702.
FIG. 18D is a front perspective view 1800 d of the MUB of FIG. 18A configured for use as a firearm platform handguard, according to an implementation of the present disclosure. In some implementations, the front surface 1804 can be configured as part of a free-floating handguard (that is, not interfacing with any firearm handguard support).
Described implementations of the subject matter can include one or more of the claimed features, alone or in combination.
Particular example implementations of the subject matter have been described. As will be apparent to those skilled in the art, other implementations, alterations, and permutations of the particular implementations are considered to be within the scope of the disclosure and the following claims. While operations are depicted in the drawings or claims in a particular order, this should not be understood as requiring that such operations be performed in the particular order shown or in sequential order, or that all illustrated operations be performed (some operations may be considered optional), to achieve desirable results.
While this disclosure contains many specific implementation details, these should not be construed as limitations on the scope of any invention or on the scope of what may be claimed, but rather as descriptions of features that may be specific to particular implementations of particular inventions. Certain features that are described in the context of separate implementations can also be implemented, in combination, in a single implementation. Conversely, various features that are described in the context of a single implementation can also be implemented in multiple implementations, separately, or in any suitable sub-combination. Moreover, although previously described features may be described as acting in certain combinations and even initially claimed as such, one or more features from a claimed combination can, in some cases, be excised from the combination, and the claimed combination may be directed to a sub-combination or variation of a sub-combination.
Accordingly, the previously described example implementations do not necessarily define or constrain this disclosure. Other changes, substitutions, and alterations are also possible within the scope of this disclosure.
