Description

[Detailed Description of the Invention] Industrial Field of the Invention The present invention relates to an improvement of a negative cord such as a small firearm (hereinafter referred to as a gun), which securely holds a terminal portion of the negative cord and has a long length in an emergency. The adjustment is made easy.

2. Description of the Related Art In the conventional negative cord 1 for a gun, the middle portion of one side of the negative cord is passed through a conventionally known buckle 100 shown in FIG. ) Mounting bracket 12 (Fig. 3)
Through the hole of the buckle, and then bend it toward the buckle side so that its end portion is passed through the buckle 100 again so as to overlap with the intermediate portion of the negative cord. After passing it through, bend it and attach the end 102 to the stopper 102 (Figs. 9 and 10).
(Fig.)

Needless to say, the conventionally known buckle 100 shown in FIG. 11 also has a length adjusting function. However, the buckle 10
If the length is adjusted at 0, two negative strings 1 are inserted into one string through hole 101 of the buckle 100, and since this part is curved, it can be pulled out by hand. Instead, the negative cord 1 is pushed out from the lower side of one side to be retained on the upper surface of the buckle 100, and this retained amount is pulled out to the other side. A typical example of the case where the length of the negative cord 1 of the gun 13 needs to be adjusted is shown in FIG. 8 and a normal case in which the gun 13 is carried on the shoulder as shown in FIG. As described above, there are cases where the gun 13 is worn around the neck to allow the user to shoot with the waist down. In reality, adjustments are made in various other cases. In the above case, the length adjustment in the case of FIG. 7 is carried out by attaching the negative cord 1 to the gun 13 according to a predetermined procedure, and then according to the length of each person's extension or the degree of obesity, to a standard dimension adapted to each person. This is an adjustment and does not require urgency, but the transition from the state of FIG. 7 to the state of FIG. To consider the conventional length adjustment with the buckle 100 from the viewpoint of urgency, at least two operations of pushing and pulling out are performed by two-handed operation, and there is a possibility that the line of sight may be off the target and the target may be lost. , It is not always satisfactory for length adjustment in an emergency.

Next, the conventional fastener 102 shown in FIGS. 9 and 10 will be examined. In the conventional stopper 102, a narrow plate 105 and an operating piece 106 connected to the narrow plate 105 are rotatably pivotally attached to a side plate 104 that is formed by bending a narrow plate 103 and has a projecting piece 107. After passing between the narrow pressure piece 105 and the narrow pressure plate 103, the engaging metal fitting
After passing 15, the bent end portions are again passed under the narrow pressure piece 105 to be overlapped with each other, and the operation piece 106 is pushed down to narrow the pressure between the narrow pressure piece 105 and the narrow pressure piece 103 to stop, and the protruding piece 107 Prevents the negative string 1 from being released from the pressure plate 103 and opening the stopper. However, in the case of the conventional fastener 102, when the canvas negative string 1 is new and lacks flexibility, it is difficult to push down the operation piece 106 by hand, and conversely, when it is opened, a driver or the like can be used. I have to pry up. On the other hand, if it is used and has a high degree of flexibility, the above tool is not required, but the narrow pressure becomes uncertain, and the negative cord 1 slips out of the stopper 102 due to the weight and vibration of the gun 13, and the gun 13 falls off. There is.

Means for Solving the Problems In order to improve the drawbacks of the above-described conventional fastener device, the present invention provides that the fastener has an edge frame having a rectangular planar shape, and the edge frames face each other. The three bridges that divide the sides at approximately equal intervals are bridged, and the two cord through holes formed by the two spaces on the center side formed by these bridges are connected to the middle part of the negative cord. Insert the terminal part of the negative string across the bridges on both sides by inserting it from one side so as to straddle the bridge, and in the two string through holes formed by the two spaces formed by the edge frame and the bridges on both sides. It is configured to be inserted from one side to securely fix the negative string except for the drawbacks of the above-mentioned conventional fasteners, and also has an adjustment function that can adjust the length in one operation in an emergency. It is a thing.

Embodiment Hereinafter, the present invention will be described in detail with reference to the drawings illustrating an embodiment. Reference numeral 3 is a base body of the fastener 2 of the present invention, which is a hollow frame body having a rectangular shape and an outer periphery surrounded by an edge frame 4. The base 3
As shown in FIG. 1, three bridges 6, 7, 8 are bridged at equal intervals between the edge frames 4 of the above, and the above hollow part is divided into four string through holes 9, 9A, 10, 10A. Make up. As shown in FIG. 2, the mounting height of these three bridges 6, 7, 8 is the lowest in the middle bridge 6, and the outer bridges 7, 8 and the edge frame 4 are substantially the same. It is mounted at a height and slightly higher than the bridge 6. The negative metal string 1 is fixed by the above-mentioned stoppers 2 as follows. The intermediate portion on one end side of the negative string 1 is inserted into the above-described conventional buckle 100, and the metal fitting 11 is attached to the terminal portion on the other end side, and when extended, it becomes one strip shape. Attach the end of one end of this negative string 1 to the mounting bracket 12
After inserting the negative cord 1 into the buckle 100 after inserting it into the hole of the gun, and attaching the mounting bracket 12 to the engaging metal fitting 14 provided on the muzzle side of the gun 13, one side of the negative cord 1 is connected to the gun 13. The mounting is the same as the conventional one. Next, after inserting the end of the portion to which the metal fitting 11 is attached into the two inner cord through holes 10 and 10A which are adjacent to each other so as to straddle the bridge 6 in the middle, the end provided to the breech side of the gun 13 is inserted. After passing through the hook 15, bend and bridge 7,8
The other side of the negative cord 1 is attached to the gun 13 by inserting the two cord through holes 9 and 9A on the outside so as to straddle the negative cord 1.
As shown in Fig. 4, the two pieces are overlapped via the bridges 7 and 8, and the terminal part with the metal fitting 11 is located relatively close to the fastener 2 so as not to interfere with the operation due to fluttering. To be installed.

As described above, when the strap 1 is attached to the gun 13 and the strap 1 is adjusted to the length shown in FIG. 7, that is, the reference dimension of each person when carrying normally, the buckle 100 is operated in the same manner as in the conventional case. Adjust the length to suit you. In order to urgently lengthen the negative cord 1 to the length shown in FIG. 8 from the standard size, the negative cords having the stoppers 2 are inserted into the cord through holes 9, 9A, 10 and 10A as described above and overlapped. The lower part of FIG. 1 in FIG. 4 is pulled to the right. Since the negative string 1 of this part only straddles one bridge 6 as shown in the drawing, and this bridge 6 is lower than the other two bridges 7 and 8,
The strap 1 has only a slight resistance to contact the bridge 6, and the double-folded portion can be easily pulled out to the right to make it longer. It has become a length. Further, when the negative cord 1 is adjusted to be shorter, the lower portion of the negative cord 1 in FIG. 4 can be easily pulled by pulling it to the left side, contrary to the above.

The length of the negative cord 1 can be easily adjusted to be short or long by pulling the lower portion of the negative cord 1 inserted through the stopper 2 in the left and right direction. However, on the contrary, the upper part straddles the two bridges 7 and 8, and when it is pulled to the left and right, it is pressed against the lower parts of the edge frames 4 on both the left and right sides, and the resistance is very large. Is impossible, and the end portion of the negative string 1 is firmly fixed by the stopper 2. This fastening is firm and reliable regardless of the old or new of the negative string 1, and when releasing the fastening, that is, when detaching from the gun 13, it is performed by the same operation as the conventional buckle 100 described above.

Next, another embodiment of the present invention shown in FIG. 5 will be described. In this embodiment, the left and right side portions of the edge frame 4 of the fastener 2 are cut by a predetermined size to provide fitting portions 12, and the middle portion of the negative cord 1 is bent as shown in FIG. It is adjusted by fitting it into the stopper 2 from the fitting portion 12, and is used when making a large adjustment at once such as when it is stored in the gun rocker. In the above description of the embodiment of the present invention, only the case where the fastener is used for the negative cord of the gun has been described, but the application of the present invention is not limited to this, and the length needs to be adjusted at the time of use. It is also effective as a fastener for all strings or bands, for example, a band for attaching a parachute.

Effect of the Invention As described in detail above, the present invention bridges three bridges between the two sides of the edge frame to form four string through holes, and connects two bridges on the center side.
Since the middle part of the negative string is inserted through one string through hole and the terminal part of the negative string is inserted through the two string through holes on both outer sides, the terminal part of the negative string can be inserted even when the negative string is loose. The two bridges can be securely attached to the fastener, and the overlapping portions of the negative strings can be made slightly so that the middle part of the negative string can be moved with a slight force with respect to the fastener, and the length of the negative string can be increased. It can be easily adjusted to a desired length instantaneously in one operation, and can be used for emergency length adjustment. Further, when the negative cord is in a tense state, the intermediate portion of the negative cord and the terminal portion of the negative cord can be pressed against each other and firmly fixed to the stopper, so that the negative cord can be surely prevented from slipping out. Further, since the three bridges are bridged between the two sides of the edge frame, it is possible to prevent the failure and damage from being caused by the simple construction of the stopper without the movable part.
