Picatinny mountable bayonets

Abstract

A bayonet mounting fixture can adapt a rifle having a mounting rail to also have a bayonet mount. Previously, bayonets were often mounted to a firearm by passing the barrel through a hole in the guard and then attaching the rear end of the bayonet to a bayonet mount or mounting lug further back. The bayonet mounting fixture can have a forward mount and a rear mount attached to the mounting rail. The forward mount has a round piece that can go inside the hole in the bayonet's guard. The rear mount can have a mounting lug to which the rear end of the bayonet is attached.

DETAILED DESCRIPTION

(25) The particular values and configurations discussed in these non-limiting examples can be varied and are cited merely to illustrate at least one embodiment and are not intended to limit the scope thereof. In general, the figures are not to scale.

(26) A bayonet mounting fixture can adapt a rifle having a mounting rail to also have a bayonet mount. Previously, bayonets were often mounted to a firearm by passing the barrel through a hole in the guard and then attaching the rear end of the bayonet to a bayonet mount or mounting lug further back. The bayonet mounting fixture can have a forward mount and a rear mount attached to the mounting rail. The forward mount has a round piece that can go inside the hole in the bayonet's guard. The rear mount can have a mounting lug to which the rear end of the bayonet is attached.

(27) FIG. 1 illustrates a bayonet mounting fixture 101 attached to the mounting rail 102 of a firearm 104 in accordance with aspects of the embodiments. Note that only the barrel and forward grip 103 of the firearm 104 are visible in FIG. 1. The illustrated forward grip 103 is a quad grip with four mounting rails 102, of which three are visible. The mounting rails 102 are Picatinny style mounting rails with recoil grooves 111. A forward mount 107 has a round piece 105 and a forward clamp 106. A rear mount 110 has a mounting lug 108 and a rear clamp 109.

(28) FIG. 2 illustrates a bayonet 201 attached to a bayonet mounting fixture 101 that is attached to the mounting rail 102 of a firearm 104 in accordance with aspects of the embodiments. The illustrated bayonet mounting fixture 101 is the same as that of FIG. 1. The guard 202 of the bayonet 201 is around the round piece 105. The latching mechanism 203 of the bayonet 201 is attached to the mounting lug 108 of the rear mount 110.

(29) FIGS. 3-6 illustrate a rear clamp assembly 300 in accordance with aspects of the embodiments. The illustrated rear clamp assembly 300 has a rear clamp body 303 integrally formed with mounting lug 108. Other embodiments can attach the mounting lug and rear clamp body using other means. The rear clamp body 303 has a nut recess 301 and a bolt groove 302. A nut 601 can fit in the bolt recess 301. A bolt threaded into nut 601 would have its shank and some threads passing along the bolt groove 302. Some embodiments can have a threaded hole instead of the nut 601 and nut recess 301. A jaw groove 501 can interface with a clamp jaw 701 to help guide the clamp jaw into the clamp body as the clamp is tightened. Rail groove 502 engages with the angled sides of a Picatinny rail to prevent the clamp from being pulled from the rail.

(30) FIG. 7 illustrates a clamp jaw 701 in accordance with aspects of the embodiments. The clamp jaw 701 has a hole 702 through which the threads and shank of a bolt can pass, as illustrated in FIG. 8.

(31) FIG. 8 illustrates a clamp jaw 701 with a nut 601 and bolt 801 in accordance with aspects of the embodiments. The threads and shank of bolt 801 have been passed through hole 702 and nut 601 threaded onto bolt 801. The clamp jaw 701, bolt 801, and nut 601 of FIGS. 7-8 can be used with either the rear mount 110 or forward mount 107 to clamp the mount to the mounting rail.

(32) FIG. 9 illustrates a rear mount 110 in accordance with aspects of the embodiments. Bolt 801 is installed in clamp jaw 701 and rear clamp body 303 such that tightening bolt 801 causes clamp jaw 701 to tighten into rear clamp body 303. The shank 902 of bolt 801 is shown in bolt groove 302. Without loss of generality, only the unthreaded shank 902 is shown with the understanding that the threads of bolt 801 may also lie with the bolt groove 302.

(33) FIGS. 10-11 illustrate a forward mount body 1101 in accordance with aspects of the embodiments. Round piece 105 is bolted to rear clamp body 1102 by a bolt 1004 sunk into hole 1005. The round piece 105 can be integrally formed with the forward clamp body 1102, but is illustrated as bolted on because it may be desirable to provide differently sized round pieces to adjust for differently sized attachment bores in bayonets. It can be seen from the figures that the clamping elements of forward clamp 107 and those of rear clamp 110 can be substantially similar with similar nut recesses, bolt grooves, and jaw grooves such that clamp jaw 701 can be used with forward mount 107.

(34) FIG. 12 illustrates a forward mount 107 and a rear mount 110 installed on a mounting rail 102 in accordance with aspects of the embodiments. The mounting rail 102 is the lowest rail on a forward grip 103.

(35) FIG. 13 illustrates a bayonet mounting fixture 1401 attached to the mounting rail 102 of a firearm 104 in accordance with aspects of the embodiments. Forward mount 1402 and rear mount 1403 are attached to one another by bridge 1404. FIGS. 14 and 16 provide a closer view of bayonet mounting fixture 1401 where it can be seen that forward mount 1402 is substantially similar to forward mount 107 and that rear mount 1403 is substantially similar to rear mount 110. FIG. 15 illustrates the bayonet of FIG. 2 attached to bayonet mounting fixture 1401 of FIGS. 13-14.

(36) FIGS. 17-18 illustrate a bayonet 1801 with Picatinny mounts in accordance with aspects of the embodiments. The bayonet 1801 has a blade 1802, handle 1803, hand guard 1804, and butt plate 1805. The hand guard 1804 and butt plate 1805 incorporate clamping mechanisms similar to those illustrated in FIGS. 3-11. A tang 1901 is illustrated as passing the full length of handle 1803, those practiced in the art of weaponry know this is a full tang embodiment. Without loss of generality, a shorter tang that ends within the handle can be used instead.

(37) FIGS. 19-20 illustrate a guard 1804 of a bayonet 1801 with Picatinny mounts in accordance with aspects of the embodiments. Guard clamp body 2002 is similar to the clamp bodies of FIGS. 3-11 with similar rail groove 502, nut recesses, bolt grooves, and jaw grooves such that tightening bolt 801 causes guard 1804 to clamp onto a mounting railed. Tang 1901 can pass through tang hole 2003 and into handle 1803. Handle interface 2004 provides for a smooth transition from handle 1803 to quillon 2001.

(38) FIGS. 21-22 illustrate a butt plate 1805 of a bayonet 1801 with Picatinny mounts in accordance with aspects of the embodiments. Butt clamp body 2202 is similar to the clamp bodies of FIGS. 3-11 with similar rail groove 502, nut recesses, bolt grooves, and jaw grooves such that tightening bolt 801 causes butt plate 1805 to clamp onto a mounting railed. Tang 1901 can pass through tang hole 2003 from handle 1803 and pinned or otherwise fixed in place to thereby assemble the bayonet. Those skilled in the art of weaponry know other techniques for assembling partial tang and full tang knives or bayonets. Butt interface 2201 provides for a smooth transition from handle 1803 to butt plate 1805.

(39) FIG. 23, labeled as Prior Art, illustrates a bayonet guard 2301 of a prior art bayonet. FIG. 23 is taken from FIG. 5 of U.S. Pat. No. 5,594,967 which has been included herein by reference and is intended to illustrate the attachment bore 2303 of bayonets that can be attached to bayonet mounting fixtures 101 and 1401. The illustrated bayonet guard 2301 has a tang hole 2302 similar to tang hole 2003 of guard 1804.

(40) It will be appreciated that variations of the above-disclosed and other features and functions, or alternatives thereof, may be desirably combined into many other different systems or applications. Also, that various presently unforeseen or unanticipated alternatives, modifications, variations or improvements therein may be subsequently made by those skilled in the art which are also intended to be encompassed by the following claims.
