The ring 6 can also release some pieces, the pieces biased by the spring structure maintaining a closed ring shape. In addition to the spring structure, the ring 6 may be connected with a screw structure to form a ring shape.

Next, the holding fitting 10 will be described in detail with reference to FIGS. 3 to 6. FIG. 3 shows a perspective view of the holding fitting 10 together with the ring 6. FIG. 4 is a schematic front view showing the internal structure of the holding fitting. 5 and 6 are perspective views showing the holding fitting 10. FIG.

The holding fitting 10 shown in FIGS. 3 to 6 includes an upper gripping part 20 and a lower gripping part 50 formed of metal, each having an upper gripping part housing 21 and a lower gripping part housing each having a sawtooth-shaped gripping function of various sizes at the tips thereof. It has a body 51.

The upper gripping part housing 21 and the lower gripping part housing 51 are provided with an arcuate space to make it easier to grip a pipe or the like when the holding fitting 10 is closed. Further, the upper grip part housing 21 and the lower grip part housing 51 are provided with first protrusions 23 and 53 which are protrusions having a trapezoidal cross section. At the tips of the first protrusions 23, 53, second protrusions 22, 52 having smaller sawtooth-like protrusions are provided. The second protrusions 22 and 52 are in an engaged state in the closed state.

The upper grip part housing 21 and the lower grip part housing 51 are provided with a hole passing through the center of the first projections 23 and 53 and a screw groove. It is provided with a rotation adjustment part 80 for adjusting the interval between the gripping parts each having a threaded part 82 that is screwed into the threaded groove. The rotation adjustment unit 80 includes a threaded portion 82 at the tip of a cylindrical support 81, and the threaded portion 82 is threaded into a threaded groove provided at the center of the first projections 23, 53.

The rotation adjustment unit 80 moves up and down along the threaded groove by gripping a cylindrical rotating rod 83 inserted into a hole penetrating the upper part and rotating the column. Then, by adjusting the interval between the respective rotation adjustment parts 80, it is possible to adjust the interval at which the gripping is performed.

The rotation adjustment unit 80 flattens the position of ABC by adjusting the position of B to the position of the second protrusions 22 and 52 (arrow β) with respect to the position of ABC shown in FIG. be able to. Normally, the flat portion is a small area of the second protrusions 22, 52, but by adjusting the position of the rotation adjustment unit 80, AB can be adjusted to be flat. As shown, it can also be fixed to a flat part of the piece 4 of the steel frame 2.

In this way, the rotation adjustment section 80 can change the position and interval at which it is held, depending on the shape of the part to be held. Although the rotation adjustment parts 80 are provided in a symmetrical pair near the center so that they can be sandwiched from above and below, they may be provided in a plurality of pairs or only one. Furthermore, if there is only one rotation adjusting section 80, the tip can be arranged within the range indicated by the arrow β.

In the upper grip part 20, as shown in FIG. 4, an upper grip part housing 21 is fixed by caulking 35 to an upper grip housing 25 formed by bending metal. The lower grip part 50 pivots the lower grip part housing 51 on the support shaft 36 of the upper grip housing 25, and also supports the lower grip part housing 51 of the lower grip part housing 61 formed by bending metal on the support shaft 37. It is pivoted on.

The lower grip part housing 51 includes a first hook part 54 and a second hook part 55, which are penetrating holes. The first hook part 54 and the second hook part 55 can hook the ring 6 shown in FIG. 3.

The lower grip part housing 51 can be rotated in the direction of the arrow α about the support shaft 36, so that it can be in a closed state or an open state. In addition, one end of the spring spring 31 serving as a biasing means is inserted into a support hole 65 that passes through the lower grip housing 51 and is hooked thereon, and the other end is bent inside the upper grip housing 25 and hooked on the support piece 26 . It is being The spring spring 31 always pulls the lower grip housing 51 toward the upper grip housing 25.

As shown in FIGS. 3 to 5, the lower grip portion 50 includes an arc-shaped handle portion 61 made of bent metal. Further, the lower grip portion 50 pivotally supports an arc-shaped release handle 63 made of bent metal on a support shaft 62 of a handle portion 61 .

An opening/closing adjustment piece 48, which is a metal piece, is pivotally supported on a support shaft 66 of the handle portion 61. The opening/closing adjustment piece 48 is inserted into the upper grip housing 25 and comes into contact with the tip of the adjustment bolt 27. The opening/closing adjustment piece 48 is always in contact with the tip of the adjustment bolt 27 by the spring spring 31.

The tip of the upper grip housing 25 forms a cylindrical grip portion 29 formed in a cylindrical shape. The cylindrical grip portion 29 has a threaded groove formed therein. The thread groove and the thread groove 28 of the adjustment bolt 27 are screwed together. By rotating the adjustment bolt 27, it moves left and right, and the opening/closing adjustment piece abutment portion 69 at the tip of the opening/closing adjustment piece 48 is moved.

Moreover, the opening/closing adjustment piece 48 moves the support shaft 37 left and right as it moves. As the support shaft 37 moves from side to side, the lower grip housing 51 can be rotated about the support shaft 36 in the direction of the arrow α, so that it can be in a closed state or an open state.

In this way, by changing the stroke of the adjustment bolt 27, even when the lock mechanism section 41 fixes the handle section 61, the opening/closing adjustment piece 48 moves and the lower grip section housing 51 rotates. It is possible to adjust the interval between grips.

Further, the release handle 63 is in contact with the side 47 of the opening/closing adjustment piece 48, and by rotating it around the support shaft 62, the side 47 of the opening/closing adjustment piece 48 is pushed up, and the opening/closing adjustment piece 48 is pushed up. As a result, the position of the support shaft 37 changes, and it is possible to change the lower grip part housing 51 to the open state to the maximum extent possible.

The release handle 63 is constantly pushed in the direction of the handle part 61 by the spring 68, and even if the locking mechanism part 41 is released, the opening/closing adjustment piece 48 does not move the release handle 63 against the force of the spring 68. It won't stay open unless it is.

Further, by grasping the handle portion 61, the position of the support shaft 37 is changed, and the support shaft 37 is rotated around the support shaft 62, so that the lower grip portion housing 51 can be changed to the closed state to the maximum extent possible.
The upper grip housing 25 includes a locking mechanism 41 so that the lower grip housing 51 can always be kept in a closed state. The locking mechanism section 41 is fixed to the upper grip housing 25 via a fixing piece 43 using fixing means 42 such as screws, welding, and caulking.

The locking mechanism section 41 is made of an arc-shaped metal or the like, and has a roller-shaped roller section 44 made of metal, rubber, or the like at its tip. The locking mechanism section 41 has a cylindrical cross section and an arc shape, but the shape is not limited to this, and it may be in the shape of a piece, as long as it has a structure that can be fixed so that the handle section 61 does not open.

Next, FIGS. 7 and 8 show another embodiment using the holding fitting 10. The same reference numerals are given to parts having the same configuration as those described above, and explanations thereof will be omitted. The holding fitting 10 holds a pipe 8 having a cylindrical cross section between an upper grip housing 21 and a lower grip housing 51.

At this time, by retracting the tip of the rotation adjusting section 80 described above to the inside of the upper gripping section housing 21 and the lower gripping section housing 51, the holding fitting 10 is moved into the upper gripping section housing 21 and the lower gripping section housing 51. Since the space can be provided in the arc shape to the maximum extent, it is possible to sandwich pipes such as scaffolding or objects with a thickness such as a rectangular prism between the first protrusions 23 and 53.

Note that the space formed by the upper grip part housing 21 and the lower grip part housing 51 is not limited to an arcuate shape, but may be circular, trapezoidal, square, polygonal, or the like. This makes it possible to easily match the shape of the object to be fixed.

Further, the holding fitting 10 is not limited to the safety belt 1, but can be used for the steel frame 2 or the pipe 8 of a scaffold as a hanging fitting for hanging a loaded load or a human scaffold.
Since it can be clamped and fixed according to the shape of the place to be fixed, it can be used not only for the safety belt 1 but also for various purposes and places.
