Can be prevented from sliding in the longitudinal direction, and the housing can be maintained in the tightening position.

  In addition, according to the present invention, the tightening force can be concentrated on the flexible bodies disposed at a plurality of positions separated in the longitudinal direction of the tightening member, and the tightening force can be increased. Can be made more difficult to slide in the longitudinal direction, and the housing can be further maintained in the tightening position.

  Further, according to the present invention, the convex base portion of the flexible body is fitted and held in the insertion groove, and the convex contact portion protrudes from the inner surface of the tightening member, so that the holding force of the flexible body is increased. In addition, the amount of protrusion of the flexible body from the inner surface of the fastening member can be reduced, and the flexible body can be reduced in size.

  Further, according to the present invention, one or the other flexible plate portion of each of the flexible bodies can be bent toward the inner surface side of the fastening member corresponding to the peripheral surface of the housing, and the fastening axis can be slightly shifted. Therefore, it is possible to easily tighten the casing whose axis is shifted from the tightening axis.

  Further, according to the present invention, it is possible to prevent the flexible body inserted from one end of the insertion groove from being pulled out by the retaining body, and it is possible to easily attach the flexible body so that it is not accidentally pulled out. it can.

  Further, according to the present invention, the ridge contact portion of the flexible body provided on the inner surface of each of the tightening members is in contact with the peripheral surface of the housing, and the ridge contact portion is tightened in a bent state.

The supported portions 632 and 632 have a flat plate shape with a circular through hole formed in the center. The supported parts 632 and 632 are arranged obliquely below and to the right of the fastener 62 in FIG. 11, and are arranged obliquely to the left in FIG.

  The supported portions 632 and 632 are in contact with the outer surfaces of the protruding plate portions 612 and 612 at one end portion of the bowl-shaped member 61. The pivot portion 64 is inserted through the through holes formed in the supported portions 632 and 632 and the protruding plate portions 612 and 612, respectively. In other words, the supported portions 632 and 632 (and extending the attachment portion 63) and the protruding plate portions 612 and 612 (and extending the hook-like member 61) are connected by the pivot portion 64.

  The pivot portion 64 is fixed to the protruding plate portions 612 and 612 and is not fixed to the supported portions 632 and 632. For this reason, the supported portions 632 and 632 can rotate around the pivot portion 64. Specifically, the pivot portion 64 is fitted in a through hole formed in each supported portion 632, and exceeds the frictional force acting between the inner surface of the through hole and the peripheral surface of the pivot portion 64. When an external force is applied, the supported portions 632 and 632 rotate.

Between the fixed portion 631 and the supported portions 632 and 632, flat arm portions 633 and 633 projecting from the fixed portion 631 are interposed. A part of each arm part 633 is provided integrally with one side part of the front side of the fixed part 631 (or the other side part of the rear side), and a supported part 632 is provided integrally with the other part of the arm part 633. ing.
As described above, the fixed portion 631 that is one side of the attachment portion 63 is fixed to the support body 3 included in the fastening tool 62. The supported portions 632 and 632 on the other side of the attachment portion 63 are rotatably supported by one end portion of the flange-shaped member 61.

When the supported parts 632 and 632 rotate, the fixed part 631 swings around the pivot part 64 via the arm parts 633 and 633. As a result, the fastener 62 swings around the pivot 64. That is, the tightening tool 62 is swingably attached to one end of the hook-shaped member 61.
The pivot 64 may be fixed to the supported parts 632 and 632 and not fixed to the protruding plate parts 612 and 612. Even in this case, the supported portions 632 and 632 are still rotatably supported at one end portion of the bowl-shaped member 61.

  In the connecting tool 6 as described above, the fastening tool 62 attached to the upper end of the hook-like member 61 fastens the casing 91, and the fastening tool 62 attached to the lower end of the hook-like member 61 holds the casing 92. By tightening, the casings 91 and 92 which are objects to be tightened are connected to each other.

  When the fastening members 1, 2 of the fastening tool 62 fasten the housing 91 (or the housing 92), the flexible body 4 provided on the inner surface of each of the fastening members 1, 2 is the circumference of the housing 91 (or the housing 92). The surface can be brought into contact with the flexible body 4 while being bent. For this reason, it is possible to eliminate the sliding movement of the casing 91 (or the casing 92) in the longitudinal direction in the tightened state. Therefore, the casing 91 (or the casing 92) can be maintained in the tightening position.

By the way, the fasteners 60 and 62 have the same configuration except for the presence or absence of the attachment shaft 31. For this reason, if the attachment shaft 31 is configured to be detachably screwed to the bottom portion 32a by a screw portion formed at the base end (that is, the side opposite to the tip having the screw portion 31a), the fastening tool 60 is provided. , 62 can be composed of parts common to each other.
If the fixed portion of the attachment portion 63 is fixed to one end portion of the hook-shaped member 61 and the supported portion is rotatably supported by the fastener 60, the support 3 of the fastener 60 is: The design must be changed to a configuration that can hold the pivot that is to be the center of rotation. In this case, the number of common parts is reduced.

Next, the fence 9 will be described with reference to FIGS. 9 and 10.
The fence 9 includes two housings 91 and 92, two support legs 93 and 93, and two connectors 6 and 6.
Each of the casings 91 and 92 is made of a metal circular tube. The casings 91 and 92 have the same dimensions.
Both left and right ends of the casings 91 and 92 are supported by support legs 93 and 93.
Each support leg 93 has a plate shape made of synthetic resin. The support leg 93 includes support portions 931 and 932 that support the housings 91 and 92.

Each of the support portions 931 and 932 has a cylindrical shape in which the axial length direction is along the left-right direction. The positions of the support portions 931 and 932 in the front-rear and left-right directions are the same, but the positions in the vertical direction are different. Specifically, the support portion 931 is disposed on the upper end portion of the support leg 93, and the support portion 932 is disposed on the center portion in the vertical direction of the support leg 93. The casings 91 and 92 are inserted through the support portions 931 and 932.
A single support leg 93 cannot be placed vertically on the ground G. However, by arranging the two support legs 93 and 93 facing each other, and further fitting both ends of the casing 91 into the support portions 931 and 931 and fitting both ends of the casing 92 into the support portions 932 and 932 The support legs 93 and 93 are stably placed vertically on the ground G.

By being supported by the support legs 93, 93, the casings 91, 92 are separated in the vertical direction and are arranged in parallel with each other in a posture along the horizontal direction.
When the fence 9 is not provided with the couplers 6 and 6, for example, when an external force is applied to the casings 91 and 92, the casings 91 and 92 may be unnecessarily deformed.
Therefore, the middle portions of the casings 91 and 92 are connected to each other by connecting tools 6 and 6.
The fence 9 is configured symmetrically. For this reason, below, the left side connector 6 shown in FIG. 9 is demonstrated.

The tightening tools 62 and 62 included in the connector 6 fasten the casings 91 and 92. However, the tightening position where the tightening tool 62 attached to the upper end portion of the hook-shaped member 61 tightens the housing 91 is the tightening position where the tightening tool 62 attached to the lower end portion of the hook-shaped member 61 tightens the housing 92. It is located on the left side. Therefore, the longitudinal direction of the flange-shaped member 61 is inclined with respect to both the longitudinal directions of the casings 91 and 92. As a result, the connector 6 functions as a bracing member that reinforces the casings 91 and 92.
For example, only one fence 9 as described above is placed on the ground G in the vicinity of the construction site, or a plurality of the fences 9 are juxtaposed so as to prohibit entry of a survivor to the construction site. Can be used as a possible rail.

Here, instead of the support leg 93 described above, it is considered to support the housings 91 and 92 using two new support legs having different vertical separation distances of the support portions 931 and 932.
In this case, it is not necessary to connect the casings 91 and 92 using a new connecting tool having a different length in the longitudinal direction of the hook-shaped member 61 instead of the connecting tool 6 described above.

This is because if the fastening members 62 and 62 are swung to adjust the inclination angle of the longitudinal direction of the casings 91 and 92 with respect to the longitudinal direction of the saddle member 61, the casings 91 and 92 are connected by the connecting tool 6. Because it is possible. Specifically, if the separation distance between the casings 91 and 92 is long (or short), the longitudinal direction of the saddle-shaped member 61 is closer to (or parallel to) the side closer to the right angle with respect to the longitudinal direction of the casings 91 and 92. The inclination angle may be adjusted.
That is, the connecting tool 6 can be shared by a plurality of types of fences having different vertical distances between the casings 91 and 92.

By the way, when the casings 91 and 92 are arranged non-parallel, the vertical separation distance in the vicinity of the left end portion of the casings 91 and 92 is different from the vertical separation distance in the vicinity of the right end portion. Even in such a case, if the fasteners 62, 62 of each connector 6 are appropriately swung, the connector 6 disposed near the left end of the casings 91, 92 and the region near the right end are disposed. The connecting tool 6 can be shared.
Similarly, even when the casings 91 and 92 are arranged at twisted positions, the casings 91 and 92 can be connected without any problem using the connecting tools 6 and 6.
As described above, the connector 6 can follow changes in the vertical distance between the casings 91 and 92, changes in the posture of the casings 91 and 92, and the like.

The embodiment disclosed this time is to be considered as illustrative in all points and not restrictive. The scope of the present invention is not intended to include the above-described meanings, but is intended to include meanings equivalent to the claims and all modifications within the scope of the claims.
In addition, as long as the effect of the present invention is obtained, the fastening tools 60 and 62, the connecting tool 6, and the fence 9 may include components that are not disclosed in the first and second embodiments.
