Description

[0001]
[Industrial applications]
The present invention relates to a band fitting, and more particularly, to a band fitting that is used for a band for fixing a human body and that can be connected without being twisted during use.
[0002]
[Prior art and problems]
As a band for fixing a human body, for example, there is a stop band for a survivor brace which is used to prevent a rescuer from falling when the rescuer is suspended by a helicopter or the like in a survivor brace.
[0003]
As shown in FIG. 5, the survivor ring is provided at both ends of the survivor ring body 1 wound around both sides of the rescuer and connected to a sling (not shown) from a helicopter. And a suspension band 2. The survivor ring main body 1 has a structure in which a stop band 3 is provided so that the survivor ring main body 1 wound under both sides is not pulled out.
[0004]
When using such a survivor ring, the survivor brace ring body 1 is passed under both sides of the rescuer, the stop band 3 is wound around the rescuer, and a female stop band fitting 4 provided on the stop band 3 is provided. After locking and fixing the male stopper band metal fittings 5, it is lifted by a sling (not shown) connected to the suspension band 2.
[0005]
As shown in FIG. 6, the band fitting includes a female fastening band fitting 4 having a substantially triangular ring-shaped portion 41 on one side of the stopping band 3, and a male fastening band fitting 4 also having a ring-shaped portion 51 on the other side. 5 are provided. The male stopper band metal fitting 5 has a structure in which a substantially hook-shaped metal fitting body 52 and a rotatable arm 53 urged in the direction of an arrow by a spring are provided on the metal fitting body 52. , And is engaged with a detent claw 521 provided at the tip of the fitting main body 52. For this reason, when the female stopper band metal fitting 4 is brought into contact with the arm 53 and pushed in, the arm 53 is rotated to the ring-shaped portion 41 of the female stopper band metal fitting 4, and the metal fitting body 52 and the arm 53 are connected. The configured ring-shaped portion 51 can pass through.
[0006]
As described above, since the planar triangular ring-shaped female retaining band 4 is fitted to the male retaining band 5, the retaining band 3 and the retaining band are slightly twisted, causing pain to the rescuer's chest. There was a disadvantage of giving.
[0007]
The present invention has been made to solve the above-described problem, and has as its object to provide a band fitting that can be connected without being twisted.
[0008]
[Means for solving the problem]
In order to solve the above-mentioned problems, a band fitting according to the present invention includes a ring-shaped portion similar to a female locking band fitting having a ring-shaped portion, and the ring-shaped portion of the female locking band fitting is connected to a ring of the male locking band fitting. In a survivor ring stop band provided with a male stop band fitting for connecting the two by passing through the shaped portion, a curved portion curved in the vertical direction is formed on a part of the ring-shaped portion of the female stop band fitting, A part of the ring-shaped portion of the male stopper band fitting is fitted into the curved portion.
[0009]
According to the present invention, since a part of the ring-shaped portion of the male retaining band fitting is fitted into a curved portion formed on a part of the ring-shaped portion of the female retaining band fitting, the retaining fitting is held in a horizontal state. This has the advantage that, for example, the rescuer's chest will not be distressed.
[0010]
【Example】
1 is a plan view of a band fitting according to the present invention, FIG. 2 is a front view, and FIG. 3 is a perspective view. As is apparent from these figures, the female retaining band fitting basically includes a substantially triangular ring-shaped portion 41, and one triangular side S from one vertex V of the triangular ring-shaped portion 41. , A curved portion 42 that is curved and rises in the vertical direction is formed.
[0011]
On the other hand, the male stopper band metal fitting 5 has a structure in which a substantially hook-shaped metal fitting body 52 and a rotatable arm 53 urged by a spring so as to rotate in the arrow direction are provided on the metal fitting body 52. The distal end of the arm 53 is engaged with a stopper 521 provided at the distal end of the metal fitting body 52.
[0012]
For this reason, when the female stopper band metal fitting 4 is brought into contact with the arm 53 and pushed in, the arm 53 is rotated to the ring-shaped portion 41 of the female stopper band metal fitting 4, and the metal fitting body 52 and the arm 53 are connected. The configured ring-shaped portion 51 is passed through. Further, since the arm 53 is biased by the spring so as to rotate in the direction of the arrow as described above, after the female stop band fitting 4 is connected, the arm 53 turns in the direction of the stop claw 521, and 521 (see FIG. 4).
[0013]
When the male retaining band fitting 5 and the female retaining band fitting 4 are connected as described above, a part of the shaft of the fitting main body 52 of the male retaining band fitting 5 fits into the curved portion 42. For this reason, the male stopper band metal part 5 and the female stopper band metal part 4 can be connected without being mutually twisted.
[0014]
In the above-described embodiment, the female retaining band fitting 4 is a triangular ring. However, the present invention is not limited to this. Any shape may be used as long as it is basically a ring. Further, the male stopper band metal member 5 is not limited to the one formed by the fishing hook-shaped metal member main body and the rotating arm shown in FIG. Any material may be used as long as it has a ring-shaped portion and a mechanism that allows the female retaining band fitting to be detachable.
[0015]
Also, in this specification, a description has been given of a stopper band metal fitting for a survivor ring, but it is clear that the band metal fitting of the present invention can be widely used as a metal fitting for a band for fixing a human body.
[0016]
【The invention's effect】
As described above, according to the present invention, a part of the ring-shaped part of the male stopper band fitting is fitted into the curved part formed in a part of the ring-shaped part of the female stopper band fitting. There is an advantage that the metal fittings are held in a horizontal state, and the rescuer's chest is not pained.
