[Conventional example]

 Conventionally, as a backpack belt locking metal fitting of this type of bag, Japanese Utility Model Laid-Open No. 61-55825 has been proposed as a "back bag ring". This conventional example has a structure as shown in FIG. 6, and in the scope of claims for utility model, “a mounting member 4 having a pipe portion 1 and base ends 5 ′, 6 of the pipe portion 1 are provided. 'Is composed of a trapezoidal frame body 5 and a stop rod body 6 which are rotatably fitted in an overlapping state. The tip end of the stop rod body 6 projects outward from the tip end of the frame body 5 in the fitted state. The back ring for a bag, characterized in that it is adapted to be engaged with the front end of the frame body 5. "

In this conventional example, the other end of the backpack belt B (indicated by the one-dot chain line in FIG. 6) whose one end is connected to the bag body is passed through the back ring, and then the other end is attached to the bag body. Rather than connecting them, the backpack belt B first connects both ends to the bag, and then the center part thereof is folded in two as shown in FIG. The backpack belt B can be securely locked by inserting the stop rod 6 into the two-folded portion through the, and the reverse operation can be performed to detach the backpack belt B. It is easy to operate and has received the most attention recently.

[Problems to be solved by the device]

 However, the above-mentioned conventional example has a problem that when the bag carrying the back ring is carried on the back, the triangularly pointed stop rod 6 faces the direction of the user's back, which may give a discomfort to the back. It was a thing. That is, since the mounting member 4 shown in FIG. 6 is fixed to the back plate of the bag, the stopper rod 6 having a triangular tip is directed toward the person carrying the bag.

[0007] However, since the frame 5 and the stop rod 6 are in a state in which the tip end side is slightly tilted upward with respect to the back plate when in use, in the unlikely event that a bag using this back ring is carried on the back, Even if you fall down, you do not have to worry about injuring your back with the rod 6, but if you exercise violently while carrying your back, the bag will shake greatly on your back, called "dancing," so sometimes you will find a triangle-shaped rod. The tip of 6 collides with the user's back and gives a feeling of strangeness. In addition, there is also a problem that there is no danger if the conditions such as pushing the bag strongly from the back in such a state that the bag is shaking greatly on the back are not completely eliminated.

Therefore, the present invention has been made to solve the above problems, and does not give a sense of discomfort even if the part facing the back of the user should collide with the back of the user, and it is a safe bag shoulder strap. The purpose is to provide a fastener.

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, in order to solve the above-mentioned problems, the structure of the present invention, which is based on the above-mentioned utility model registration claim, is provided with a long parallel side portion 11 of the first trapezoidal first body 10. The mounting board 20 in the form of two folds is connected so that the longer parallel side portion 11 is wound in the folded portion 22, and the upper and lower flat surface portions 21 and 21 of the mounting board 20 overlap each other. Pierces through the rivet holes 23, 23, 23 penetrating therethrough, and on the ring main body 10, the length of the lower side portion 32 is equal to or greater than the length of the shorter horizontal side portion 12 of the first body 10. The second annular body 30 having the triangular contour shape is overlapped so that the lower side portion 32 overlaps the shorter parallel side portion 12 and the lower side portion 32 and the parallel side portion 12 are combined with each other. Connect the upper part of the ring body 30 with a spring 40 that urges it toward the first body 10 side. On the upper part of the second annular body 30, a belt engaging portion 31 bent in a hook shape is provided on the side opposite to the first body 10, and the lower side portion 32 and the parallel side portion 12 have a spring 40. Including the above, the technical means of enclosing with the cover cylinder 41 is taken.

[Action]

 Next, the operation of the present invention will be described. As shown in FIG. 1, the backpack belt metal fitting of the bag of the present invention is attached to the upper central part of the back plate of the bag 50 by fixing its mounting substrate 20 by tacking or the like. It should be noted that locking rings 52, 52 called D rings are attached to both lower sides of a back plate 51 of the bag 50. Separately from the bag 50, a backpack belt B having eggplant rings B1 and B1 at both ends is prepared.

According to the present invention, when the mounting substrate 20 is fixed to the back plate 51, the first parallel body 10 is connected so that the longer parallel side portion 11 is wound inside the folded-back portion 22. The first body 10 has a function of being attached to the back plate 51 so as to be able to move back and forth.

Since the second ring member 30 is connected to the shorter parallel side portion 12 of the first member 10 by the spring 40, the second ring member 30 is always attached with the spring 40. Although it is in close contact with the first body 10 due to the force, it exerts an action of being attached to the first body 10 so as to be able to lie down and up.

Therefore, in order to attach the backpack belt B to the bag 50, first, the eggplant rings B1 and B1 at both ends of the backpack belt B are locked to the locking rings 52 and 52. Then, the first body 10 is lifted from the back plate 51, and the central portion of the backpack belt B is folded in half and inserted from below. At this time, the second annular body 30 is lifted from the first body 10 against the urging force of the spring 40, and the two-folded portion at the center of the backpack belt B is pulled out from the inside of the first body 10. When the second annulus 30 is made to be inserted in the ring and both ends of the backpack belt B are pulled to both sides, as shown most clearly in "Fig. 5", the backpack belt B is in the first part. From below the hypotenuse part 13 on one side of the body 10 to above the second ring body 30 and below the hypotenuse part 13 on the other side of the first body 10, to form the first body 10 and the second ring body 30. It is locked by and.

Further, since a belt locking portion 31 bent in a hook shape is provided on the upper side of the second annular body 30 on the side opposite to the first body 10, the locking is performed as described above. One side of the backpack belt B is locked by the belt locking portion 31 and serves to prevent the locking from being disengaged.

When the bag 50 is carried on the back, a load is applied to push down the tip of the second ring body 30 (the left end of “FIG. 5”) and lift the lower side portion 32 of the second ring body 30. Since the lower side portion 32 of the first part body 10 and the lower side portion 32 of the second ring body 30 are covered by one cover cylinder body 41, they are not separated from each other by a predetermined amount or more, and they are connected to each other. The spring 40 has a function of preventing the spring 40 from being damaged or falling off.

The cover tubular body 41 has a large contact area even if it comes into contact with the back, so that the cover tubular body 41 does not give an uncomfortable feeling.
