ない欠点を有する。又st。Conventional technology and its problems It is widely known that detachable legs are attached to military guns to improve shooting accuracy, and many legs dedicated to each gun have been proposed and used. The breech leg must not fall off the gun during combat operations with intense movement, and must be easy to attach and detach. Considering the conventionally used legs from this point of view, there is one (M16) in which the two leg levers are always urged to the open leg state by springs and does not have a locking mechanism for one leg lever. Since this leg does not lock the leg rod, there is a risk of it falling off as described above, and furthermore, when it is removed from the gun and carried, it has the disadvantage that it must be stored in the case against the spring force. Also st.

作部が小さく手袋使用時等の操作性に問題があるもの、
更に銃には着脱する際に特殊な操作を必要とし、緊急時

すべてを満足し得るものはない。ner63 has a locking device, but the operation part is small and there are problems with operability when using gloves, etc.
Furthermore, some guns require special operations when being attached and detached, and some have problems when attached and detached in an emergency (HK), etc. Each type has its own advantages and disadvantages, and there is no one that can satisfy all of them.
問題点を解決するための手段 本願は上記従来使用されている脚の改良に係り。Means to solve problems This application relates to improvements to the legs conventionally used above.
一方の脚杆の枢支基部に銃軸方向に貫通する嵌挿孔と、
該嵌挿孔の一方側の入口にカム溝を設け。An insertion hole penetrating the pivot base of one of the leg rods in the gun axis direction;
A cam groove is provided at the entrance on one side of the insertion hole.
又上記嵌挿孔内には、背面に斜状の引上面と保持面及び
係止片からなる弧状のカムを突設した操作片を取付けた
ロックピンを、カムをカム溝に嵌入するとともに、ばね

して従来の欠点を除いたものである。Further, in the insertion hole, a lock pin is attached with an operation piece having an arc-shaped cam protruding from the back surface consisting of an inclined lifting surface, a holding surface, and a locking piece, and the cam is inserted into the cam groove. A spring biases the insertion hole in the direction of protrusion, and the leg rod on the opposite side is provided with a locking pivot, which is an extension of the pivot piece, so that the insertion hole can be inserted into the insertion hole both when the legs are opened and when the legs are closed. This eliminates the drawbacks of the prior art by locking the locking pivot on a slightly protruding locking pin.

FIG. 1 is a front view of the leg 1 of the present invention seen from the muzzle side with a part (the lower end of the script body to be described later) omitted, and one leg rod 2, 2A is connected to the script body 3, 3A and the leg head 4.4A. Both of them are pivoted so that one main body 3.3A can be folded to the bleaching side via a conventionally known folding mechanism 5. Also, both leg rods 2゜2A have two pivot pieces 7.7 on each of the muzzle and breech sides protruding from the pivot base 6.6A of the single leg head 4, 4A.
A, 8, and 8A are rotatably pivoted by a pivot 9, and both leg rods 2.2A are biased in the leg opening direction by a spring 10 attached to the pivot 9, so that the legs are in the open leg state shown in FIG. The gun barrel (not shown) is gripped by the gripping piece 11 at the upper end of the pentapod head 4, 4A, and the above is the same as the conventional leg. The device is designed to lock in place and firmly maintain the open and closed leg states, and is constructed as follows.

のを制している。In the drawing, reference numeral 12 denotes a fitting hole that passes through the pivot base 6 of the leg head 4 in the gun axis direction, and the breech side is a spring storage chamber 12A, and the muzzle side of the fitting hole 12 has a cam groove 13. In this embodiment, the inner part of the cam groove 13 communicates with the insertion hole 12, and two pairs of cam grooves 13 are drilled at target positions like butterfly wings. It is not limited to what is shown in the drawings as long as it satisfies the following, and the object of the present application can be achieved with a minimum number of pieces. Next, 14 is a lock pin, and the following operation piece 15 is attached to the head of the lock pin 14 on the muzzle side. Two arcuate cams 16 are provided on the back surface (breach side) of the operating piece 15 to correspond to the cam grooves 13. A flat pulling surface 18 connected to the slanted lifting surface 17 and a locking piece 19 slightly protruding from the pulling surface 18 are provided, and the lock pin 14 to which the operating piece 15 is attached is attached to the cam. 16 is inserted into the cam groove 13, and is urged by the spring 20 to protrude toward the breech side of the insertion hole 12, and is inserted into the insertion hole 12. At this time, the tip of the lock pin is inserted into the pivot base. The length of the lock pin 14 is set so that it slightly protrudes toward the breech side of the cam groove 13, and as shown in FIG. 3, and prevents the operation piece 15 from rotating in the counterclockwise direction when viewed in FIG.
最後にロック板21について説明する。ロック板21は
第2図に示すように、上記脚杆2と反対側の脚杆2Aの
ブリーチ側に突設した枢支片8Aを延長して設けられ、
上側前端が弧状の開脚ロック面2LA下側の側縁が閉脚
ロック面21Bとなっている。Finally, the lock plate 21 will be explained. As shown in FIG. 2, the lock plate 21 is provided by extending a pivot piece 8A protruding from the breech side of the leg rod 2A opposite to the leg rod 2,
The leg opening locking surface 2LA has an arcuate upper front end, and the lower side edge thereof serves as a closing leg locking surface 21B.
以上のように構成された本願脚1を使用しない場合、す

脚状態にロックされる。When the legs 1 of the present invention configured as described above are not used, that is, when carried with the legs closed without being attached to a gun,
As shown in FIG. 3, the leg closing surface 21B of the lock plate 21 is attracted to the protruding portion of the lock pin 14, and the biasing force of the spring 1o is suppressed, so that the leg levers 2 and 2A are brought into the closed state without opening. locked.

クピン14はばね20を圧しながら引き上げられ。When mounting the gun on a gun, the lock is released, and the process of releasing the lock will be explained with reference to FIG. FIG. 7A shows the state shown in FIG. 3, that is, the locked state, in which the locking piece 19 hits the side wall 13A of the cam groove 13, and the operating piece 15 does not rotate counterclockwise. From the above, as shown in FIG. 7B, operation piece 1
5 in the clockwise direction, the slanted lifting surface 17 will align with the cam groove 13.
The lock pin 14 engages with the side wall 13A of the lock pin 14 and slides up, whereby the lock pin 14 is pulled up while pressing the spring 20.

ロックを開放した状態に保持される。The tip of the lock pin 14 that has been protruding until now is flush with the side surface on the breech side or slightly inserted into the insertion hole 12 to release the lock, and the leg rod 2.2A is moved to the first position by the force of the spring 10.
Spread your legs as shown. When the operating piece 15 is further turned, the engaging surface 18 rides on the side surface of the leg head 4 (pivot base 6) and engages the locking pin 14, and then the engaging piece 19 engages in the cam groove as shown in FIG. 7C. When the operating piece 15 hits the side wall 13A of the holder 13 and has rotated about 45', the operating piece 15 stops rotating, and the lock pin 14 is held in an unlocked state.
ロックが開放された本願脚1を銃に装着する場合には、
−杯に開脚している脚杆2.2Aを所定角度押し戻して
把持片11を開き、再び脚杆2.2Aを一杯に開脚させ
ることにより装着される。When attaching the unlocked leg 1 to a gun,
- It is attached by pushing back the leg lever 2.2A that is opened to the cup by a predetermined angle to open the gripping piece 11, and then fully opening the leg lever 2.2A again.

ク板21の開脚ロック面21Aを係止してロックする。To release the lock of the leg rod 2.2A of the attached leg 1, the operation piece 15 rotated as described above is turned in the opposite direction, and the operation piece 15 is momentarily moved by the force of the special spring 2o, which is clear from FIG. As shown in FIG. 2, the lock pin 14 engages and locks the open leg lock surface 21A of the lock plate 21.
又銃により脚1を取り外す時のロック開放、更に閉脚し
た脚杆2.2Aのロックは、上記した開放及びロック動
作を繰返すことによって行うことはいうまでもない。It goes without saying that the locking and unlocking when the leg 1 is removed by a gun and the locking of the closed leg rod 2.2A are performed by repeating the above-described opening and locking operations.

Furthermore, it is easy to put on and take off, and the locking mechanism has good operability, so it can be used regardless of usage conditions such as wearing gloves. Furthermore, since the leg rods are locked even when the legs are closed, it has the advantage of being able to be smoothly taken in and out of the storage case when attaching and detaching the carrying case, or on the bleach side (back side) of the operating piece.
