Quick acting modular rifle interface

Abstract

The invention relates to quick acting interfaces that allow for easier transportation and maintenance of precision rifles. Embodiments include an interface with an engaging segment and a receiving segment that engage one another and lock together. The engaging segment may have a series of connective bearings that fit into indentations inside the receiving segment. Embodiments allow a firearm to be modulated such that a barrel of the firearm may be disassembled without the need of any specialized equipment and reassembled without impacting the firearm's accuracy or reliability. Embodiments are scalable such that multiple interfaces can be used to adjust the total length of the firearm barrel.

DETAILED DESCRIPTION OF EMBODIMENTS OF THE INVENTION

(12) Embodiments of the disclosure described herein are not intended to be exhaustive or to limit the disclosure to precise forms disclosed. Rather, the embodiments selected for description have been chosen to enable one skilled in the art to practice the disclosure.

(13) Generally, an embodiment of the present invention allows for a firearm to be modulated such that a barrel of the firearm may be disassembled without the need of any specialized equipment, such that the firearm may be transported in a more compact manner. The modulation of the barrel will have negligible effects on the operation of the firearm (i.e., loss of accuracy, firearm malfunction, added weight).

(14) Referring to FIG. 1, a quick-acting modular rifle interface 101 may be seen. The quick-acting modular rifle interface 101 may include a plurality of segments that can be interlocked together. In some embodiments, there may be two segments, while other embodiments may include more segments, for example, three or more segments may be used. FIG. 1 shows a receiving segment 103 and an engaging segment 105 coupled together via a connection mechanism. Receiving segment 103 and engaging segment 105 may be made of any suitable material used in constructing rifle barrels such as stainless steel, steel alloys, carbon steel, chrome molybdenum, or any other material known in the art.

(15) There are multiple places on the rifle that one or more quick-acting modular rifle interfaces 101 could be positioned, some embodiments include where the barrel connects with the rifle receiver and/or one or more places along the barrel. In an exemplary embodiment, the quick-acting modular rifle interfaces 101 may comprise engaging segment 105 that can be permanently affixed to the rifle receiver at a pre-set location.

(16) FIG. 2 shows an exemplary embodiment of the quick-acting modular rifle interface 101 when the device is uncoupled. In at least one embodiment, engaging segment 105 may contain a plurality of connective bearings 201 as the connection mechanism. In other embodiments the connection mechanism may comprise any suitable removable fastener known in the art, including, but not limited to, threaded fasteners, magnets, bolts, pins, pneumatic couplers or the like. In some embodiments, the quick-acting modular rifle interface 101 may include a matching, serialized bolt that has already been head spaced to the barrel. This may allow for the rifle's barrels to be replaced without the necessity of sending it to a specialty shop for replacement and head spacing with special tools, making field replacement of barrels possible. Additionally, because the serialized bolt has already been head spaced and match to the barrel, replacement of the barrel and bolt with a new serialized barrel/bolt combination of a different caliber is possible. A non-limiting example would be to replace a .308 Winchester barrel/bolt combination with a .338 Lapua Magnum barrel/bolt combination.

(17) The quick-acting modular rifle interface 101 may have an engaging segment 105 and a receiving segment 103 that engage one another and lock together. The engaging segment 105 may have a series of connective bearings 201 that fit into indentations (not shown) inside the receiving segment 103. In some embodiments this may have the effect of acting as locking lugs.

(18) In some embodiments, the receiving segment 103 may be include a receiving thread (not shown) threaded in a direction opposite of the thread in the engaging segment 105. The opposing thread may disengage the two segments by retracting the connective bearings 201 into the engaging segment 105 as shown in FIG. 3, allowing the two segments to be separated.

(19) In some embodiments, the engaging segment 103 may include at least two or more cylindrical shaped portions. The portions may comprise separate, distinct outer radii. In one example, as shown in FIG. 2, the engaging segment may comprise four portions (a barrel portion 113, a bearing portion 111, a threaded portion 109, and a connector portion 115).

(20) The retracted connective bearings 201 may be positioned such that the outer surface of the connective bearings 201 may be closer to the center of the cylindrically shaped engaging segment 103 than the outer radius of the bearing portion 111. The retracted connective bearings may make it possible to easily separate the engaging segment 105 from the receiving segment 103. Thus, allowing the barrel to be deconstructed for stowage and transportation.

(21) Referring to FIG. 4, the connective bearings may be positioned to a protruding position. The protruding connective bearings 201 may be disposed such that the extend further from the center of the engaging segment 103 than the outer radius of the bearing portion 111. The receiving segment 103 may be threaded onto the engaging segment 105 where, once in place, the connective bearings 201 may lock into the indentations found in receiving segment 103. Once the connective bearings 201 are engaged, the quick-acting modular rifle interface 101 may sufficiently withstand the shock and other force generating actions associated with firing a precision rifle.

(22) FIG. 5 shows an exemplary version of a rifle that has been fully disassembled and stowed away in a carry case for easy transportation. In some embodiments, the disassembled rifle may be configured to fit in a case smaller than 20×20 in. Other embodiments, allow storage of the disassembled rifle in a case larger than 20×20 in.

(23) While FIG. 1 may only show a connection area of the receiving segment 103 and engaging segment 105, other embodiments may contain a hollow cylindrical extension protruding from the quick-acting modular rifle interfaces 101 defining a barrel extension 601. In some embodiments, the engaging segment 105 and/or the receiving segment 103 may contain a barrel extension 601 as seen in FIG. 6. A barrel extension 601A may be affixed to the receiving segment 103 and a barrel extension 601B (not shown) may be affixed to the engaging segment 105 may be substantially the same size. Barrel extension 601A and 601B may be configured to align when the receiving segment 103 is coupled to the engaging segment 105, such that barrel extension 601A when acting in connection with the barrel extension 601B form the entire barrel of the precision rifle. In some embodiments barrel extension 601A may comprise up to 95% of the total length of the rifle barrel, while in other embodiments, the barrel extension 601A may comprise only 5% of the total length of rifle barrel, or percentage in between. While some quick-acting modular rifle interfaces 101 may comprise barrel to a barrel interface, others may comprise a barrel to receiver interface.

(24) FIG. 7 shows a latitudinal cross-sectional view of one embodiment of a cylindrical quick-acting modular rifle interface 101. The barrel extension 601A may be defined as the hollow circular region with the smallest diameter. In the embodiments where the receiving section 103 and engaging section 105 may be locked together via connective bearings 201. In some embodiments, the receiving segment 103 may be joined to the engaging segment 105 through the use of threaded sections located on each segment. The receiving segment 103 and engaging segment may be rotated to further engage the threads. As the threads become more interconnected by rotating the receiving segment 103 and engaging segment 105, the connective bearings 201 on the engaging segment 105 may protrude from the bearing portion 111 and insert into indentations found in receiving segment 103. The introduction of the connective bearings 201 into the indentations may lock the receiving segment 103 and engaging segment 105 together such that the locking of the segments is able to withstand significant forces associated with the use and handling of a rifle.

(25) Although the invention has been described in detail with reference to certain preferred embodiments, variations and modifications exist within the spirit and scope of the invention as described and defined in the following claims.
