When wiring or piping wiring materials such as cables and signal lines, or piping materials such as electrical conduits and water supply pipes along the installation route, place the support that accommodates and supports the wiring and piping materials in the support section in the installation direction. They are placed at predetermined intervals. When installing wiring and piping materials, multiple wiring and piping materials are often laid in parallel along walls, floors, etc., so it is necessary to lay multiple wiring and piping materials in line. In some cases, a plurality of supports are connected in parallel. FIG. 8 shows a support device described in Patent Document 1, and this support device allows multiple wiring/piping materials to be placed vertically along a wall surface etc. by arranging a plurality of supports vertically in parallel along a wall surface, etc. Can be installed in parallel.

As shown in FIGS. 8(a) and 8(b), the support described in Patent Document 1 is provided with a fixing part 63 having a screw insertion hole 62 in the upper part and a holding protrusion having a screw insertion hole 64 in the lower part. 65 are provided. Further, below the bottom wall 66, a protrusion 67 is provided which can be fitted into and locked into the screw insertion hole 62 of the fixing part 63.

In order to vertically connect one support 60 and the other support 61, one is inserted into the screw insertion hole 62 of the fixing part 63 of the other support 61, as shown in FIGS. Place the other support 61 on one support 60 in the direction of the arrow so that the protrusion 67 of the support 60 fits into it, and insert the protrusion 67 into the screw insertion hole 62 of the fixing part 63, so that the two Assemble the supports up and down. Thereafter, a screw is inserted into the screw insertion hole 62 of the fixing part 63 of one support 60 to fix it to the wall surface 50, and a screw is inserted into the screw insertion hole 64 of the holding protrusion 65 of the other support 61. and fix it to the wall surface 50.

However, in the support described in Patent Document 1, the other support 61 can only be assembled in the vertical direction from the back side of the bottom wall 66 of one support 60, that is, from the wall surface 50 side. After installing the support 60 on the wall, it was not possible to connect and install the other support 61 below the support 60. That is, the two upper and lower supports could not be fixed to the wall surface 50 unless they were assembled together.

Also, after connecting the two supports vertically and fixing them to the wall surface 50 by inserting a screw into the screw insertion hole 62 of the upper fixing part 63, insert the screw into the screw insertion hole 64 of the lower holding protrusion 65. If the cable is supported by the receiving part 68 before fixing it to the wall surface 50, the cable will block the front of the screw insertion hole 64 and get in the way, making it difficult to insert the screw into the holding protrusion 65. It was difficult to fix screws into the holes 64. This is the same when fixing only one support, and after fixing the fixing part 63, the cable is supported by the receiving part 68, and then the screw is fixed to the screw insertion hole 64 of the holding protrusion 65. was difficult to work with.

Therefore, the present invention can be installed and fixed by connecting it later to something that is fixed to a structure, and in a structure that has fixing parts on both the upper and lower sides, the wiring can be fixed after being fixed to the structure with the upper fixing part. - It is an object of the present invention to provide a connecting device that can fix a screw to a lower fixing part without any problem even when the piping material is supported.

Hereinafter, a connecting device according to an embodiment of the present invention will be described based on the drawings. In the following, the vertical direction in FIG. 1 will be described as the vertical direction of the actual product.

In FIGS. 1 and 2, a wiring/piping material support (hereinafter simply referred to as "support") includes a base 10 having fixing parts at both ends with screw insertion holes for fixing to a structure; A wiring/piping material support section (hereinafter simply referred to as "support section") extending from 10 is provided. As shown in FIG. 3, the support 1 has both fixing parts fixed to the structure with screws, and one of the fixing parts is attached to the other support 1A. The screw 40 is overlapped with the other fixed part 15 in the insertion direction, and the other support 1A is aligned with the direction of alignment of both fixed parts, and the other fixed part 15 is fixed to the structure with the screw. The screw can be connected without interfering with the head 41 of the screw 40 inserted into the other fixed part 15 of the support 1A, and is inserted into the screw insertion hole 16 of the other fixed part 15 in the connected state. 40, it can be fixed to a structure. In this embodiment, a wall surface 50 of a building is exemplified as a structure, and a cable is exemplified as a wiring/piping material. Each component will be explained in detail below.

In FIGS. 1 and 2, the base 10 has a pair of side walls 12 erected on both left and right sides of a vertically long rectangular plate-shaped bottom wall 11, and is fixed to the upper end along a wall surface 50. A fixing part 13 is provided with a screw insertion hole 14 that can be fixed with a screw. Furthermore, a fixing part 15 is provided at the lower end of the base 10 and has a screw insertion hole 16 that can be fixed with a screw for fixing along the wall surface 50.

At the upper end of the base 10, as shown in FIG. 4, a hook 17 is provided for vertically connecting the supports 1 to each other. As shown in FIGS. 1, 2(c), and 4(e), the hooking portion 17 is attached to each of a pair of side wall portions 12, 12 that protrude in a hook shape toward the support portion 30 at the upper end portion of the base portion 10. A pair of flange-like hooking pieces 18, 18 are formed to protrude from the upper end in directions facing each other. The hooking portion 17 is formed to have a substantially C-shaped cross section, and a hooked portion 33, which will be described later, can be inserted into the internal space thereof. A slit-shaped gap is formed between the pair of hook pieces 18, 18 of the hook part 17, and the gap constitutes a receiving space 20 into which a reinforcing wall 32, which will be described later, is fitted. It is formed to have approximately the same size as the plate thickness of No. 32. In addition, the gap 19 between the hooking piece 18 and the bottom wall portion 11 shown in FIG. It is now possible to do so.

Furthermore, a pair of flange-shaped hook pieces 21, 21 are provided at the intermediate portion of the base 10 so as to protrude from the tip of each side wall portion 12 in a hook-like manner in directions facing each other. As shown in FIG. 6, the pair of hook pieces 21, 21 constitute a second hook portion 22 for laterally connecting the supports 1 to each other. The gap between the pair of hooking pieces 21, 21 of the second hooking part 22 for horizontal coupling constitutes a receiving space 24 for horizontal coupling into which a reinforcing wall 36 for horizontal coupling, which will be described later, is fitted. The interval is formed to be approximately the same size as the plate thickness of the reinforcing wall 36. In addition, the gap 23 between the hooking piece 21 and the bottom wall portion 11 shown in FIG. The second latched portion 35 is press-fitted into the second latched portion 35 .

Here, the gap L between the fixing part 13 at the upper end of the support 1 and the fixing part 15 at the lower end of the other support 1A, shown in FIG. 4(d), is larger than the height of the head 41 of the screw 40. formed to the dimensions. This prevents the head 41 of the screw 40 inserted into the fixing part 15 at the lower end of the other support 1A from interfering with the fixing part 13 at the upper end of the support 1 after the two supports are connected. Ru.

On the other hand, the support section 30 extends horizontally from the bottom wall section 11 at a lower portion of the base section 10 and above the fixing section 15 at the lower end. The support portion 30 is formed into an arcuate plate shape, and has a mounting surface 31 for supporting the cable. A reinforcing wall 32 that hangs downward is provided below the mounting surface 31. Further, on the lower end side of the reinforcing wall 32, a hooked portion 33 is provided that extends horizontally and is capable of hooking the hooking portion 17 at the upper end. The plate thickness of the latched portion 33 is formed to be slightly larger than the gap 19 between the latching piece 18 of the latching portion 17 and the bottom wall portion 11, so that the latched portion 33 is elastically inserted into the interior of the latching portion 17. It can be press-fitted into the space, and the latched portion 33 is held between the latching portions 17 so that the two supports are vertically connected.

A vertical wall 34 is formed on the distal end side of the mounting surface 31, and the vertical wall 34 is slightly inclined with respect to the base 10 in a direction in which the upper part becomes narrower. A second hooked portion 35 for horizontal connection in the shape of an L-shaped plate is protruded from the vertical wall 34 , and a gap between the second hooked portion 35 and the vertical wall 34 is formed by the second hooked portion 22 . The plate thickness is the same as or slightly smaller than that of the stopper piece 21. Furthermore, a rectangular plate-shaped reinforcing wall 36 is provided between the second hooked portion 35 and the vertical wall 34 at the widthwise intermediate portion, and the thickness of the reinforcing wall 36 is equal to that of the pair of hooking pieces. It is formed to have approximately the same size as the gap between 21 and 21.

Next, a method of fixing the support 1 formed in this manner to the wall surface 50 while vertically connected to another support 1A fixed to the wall surface 50 will be described.
As shown in FIG. 3(a), the other support 1A is attached to the wall surface 50 by inserting screws 40 into the screw insertion holes 14 of the fixing part 13 at the upper end and the screw insertion holes 16 of the fixing part 15 at the lower end. Fixed. Therefore, with respect to this other support 1A, the reinforcing wall 32 is inserted into the receiving space 20 so that the hook portion 17 of the support 1 is brought close to the reinforcing wall 32 of the other support 1A from below. Next, as shown in FIG. 3(b), the hooking portion 17 of the support 1 is horizontally slid toward the base 10 to insert the hooked portion 33 into the internal space of the hooking portion 17. After insertion, the gap 19 between the latching piece 18 of the latching part 17 and the bottom wall part 11 is slightly smaller than the plate thickness of the latched part 33, so the latched part 33 has a gap between the latching piece 18 and the bottom wall part 11. 11, and the ends of the base portions 10 of both supports are overlapped in the insertion direction of the screw 40, that is, from the right direction to the horizontal left direction in FIG. 3(b). Thereafter, by inserting the screw 40 into the screw insertion hole 16 of the fixing part 15 at the lower end of the support 1 and tightening the screw, the support 1 can be attached to other parts as shown in FIG. 3(c) and FIG. It is fixed to the wall surface 50 while being vertically connected to the support 1A. The support 1 and the other support 1A connected in the vertical direction constitute a connection device 2.

At this time, the fixing part 13 at the upper end of the support 1 is connected without interfering with the head 41 of the screw 40 inserted into the screw insertion hole 16 of the fixing part 15 at the lower end of the other support 1A. . Note that since the hooking part 17 of the support 1 is hooked in a direction close to the wall surface 50, even if the fixing part 13 at the upper end slightly interferes with the head 41 of the screw 40, the fixing part 15 at the lower end By fixing it, it is possible to stably fix it to the wall surface 50, although it is slightly inclined. Therefore, the gap between the fixing part 13 at the upper end of the support 1 and the fixing part 15 at the lower end of the other support 1A does not need to be strictly larger than the height of the head 41 of the screw 40.

Here, in the support 1 connected in this way, the support 1 also corresponds to the hanging body in the claims, and the other support 1A also corresponds to the base body and the wiring/piping material receiver in the claims. However, a device in which these are connected corresponds to a connecting device in the claims. Further, the reinforcing wall 32 also corresponds to a wall portion in the claims, the hanging portion 17 and the receiving space 20 also correspond to a connecting portion, and the supporting portion 30 also corresponds to a wiring/piping material receiving portion, The gap between the fixing part 13 at the upper end of the support 1 and the fixing part 15 at the lower end of the other support 1A also corresponds to the head accommodation space.

Next, a plurality of supports may be connected in the vertical direction and then fixed to the wall surface 50.
As shown in FIG. 5(a), the reinforcing wall 32 of the other support 1A is inserted from below into the receiving space 20 of the support 1, and the hook part of the support 1 is 17 is horizontally slid toward the base 10 side of the other support 1A, and the hooked portion 33 of the other support 1A is inserted into the internal space of the hook 17. After insertion, as shown in FIG. 5(b), the latched portion 33 of the other support 1A is held between the latching piece 18 of the latching portion 17 of the support 1 and the bottom wall portion 11, and both The ends of the base 10 of the support are connected in an overlapping state in the insertion direction of the screw 40.

At this time, a gap is formed to accommodate the head 41 of the screw 40 between the fixing part 13 at the upper end and the fixing part 15 at the lower end of the other support 1A. Moreover, the relative positions of the screw insertion holes of the overlapping upper end fixing part 13 and the lower end fixing part 15 of the other support 1A match. Therefore, the screw insertion hole 14 of the fixing part 13 at the upper end of the other support 1A, the fixing part 13 at the upper end of the support 1 that overlaps and communicates, and the fixing part 15 at the lower end of the other support 1A. The screws 40 are inserted into a total of three locations, including the screw insertion holes 16 and 16 of the fixing part 15 at the lower end of the support 1, and tightened. As a result, as shown in FIG. 5(c), the support 1 is fixed to the wall surface 50 while being vertically connected to the other support 1A.

Next, the operation of the support tool 1 of this embodiment will be explained.
The support 1 has a fixing part 13 at the upper end of the other support 1A fixed to the wall surface 50 with screws, and a fixing part 15 at the lower end of the other support 1A in the insertion direction of the screw 40. Since it is possible to connect with the head 41 of the screw 40 inserted into the fixing part 15 at the lower end of the other support 1A in a superposed state, the other support fixed to the wall surface 50 can be connected. It can be connected to the tool 1A later and fixed to the wall surface 50.

Further, the support 1 has fixing parts with screw insertion holes at both the upper and lower ends of the base 10, and the support part 30 extending from the base 10 is located above the fixing part 15 at the lower end. Even after fixing the cable to the wall surface 50 with the upper fixing part and supporting the cable with the support part 30, the cable does not get in the way of fixing and does not interfere with the screw insertion hole 16 of the fixing part 15 at the lower end. It can be fixed to the wall surface 50 by inserting the screw 40 without having to do so.

As described above, the support 1 can also be fixed to the wall surface 50 after being assembled with another support 1A. In this case, the relative positions of the screw insertion holes of the overlapping upper end fixing part 13 and the lower end fixing part 15 of the other support 1A match. Therefore, both screw insertion holes communicate with each other, and the screw 40 can be inserted in a state where it is connected to the other support 1A.

Furthermore, by simply inserting the reinforcing wall 32 into the receiving space 20 and sliding the hooking part 17 of the supporter 1 toward the base 10 side with respect to the hooked part 33 of the other supporter 1A, the supporter 1 can be easily assembled to another support 1A.

By the way, although the above-mentioned embodiment describes the connecting device 2 in which two supports are connected in the vertical direction, the support device 1 of this embodiment can also be made into a connecting device 3 that connects in the horizontal direction. .

As shown in FIG. 6(a), the other support 1A is fixed to the wall surface 50 by inserting screws 40 into the respective screw insertion holes of the fixing part 13 at the upper end and the fixing part 15 at the lower end. With respect to the second hooked portion 35 of the other support 1A, the second hook 22 of the support 1 is reinforced from above in the receiving space 24 in proximity to the reinforcing wall 36 of the other support 1A. Insert wall 36. Next, the second hook part 22 of the support 1 is slid vertically downward, and the second hook of the other support 1A is inserted into the gap between the hook piece 21 of the second hook part 2 and the bottom wall part 11. Insert the stop 35. After insertion, the gap between the hooking piece 21 of the second hooking portion 22 of the support 1 and the bottom wall portion 11 is slightly smaller than the thickness of the second hooked portion 35 of the other support 1A. The second latched portion 35 of the support 1A is held between the latching piece 21 of the second latching portion 22 of the support 1 and the bottom wall portion 11, and is held between the bottom wall portion 11 of the base 10 of the support 1. The vertical walls 34 of the other support 1A are laterally overlapped. Thereby, as shown in FIG. 6(b), the support 1 is laterally connected to the other support 1A fixed to the wall surface 50.

Here, as shown in FIG. 6, the distal end side of the supporting portion 30 as a whole is slightly raised upward, and the vertical wall 34 is slightly inclined with respect to the base portion 10 in a direction in which the upper portion becomes narrower. The reason why the support portion 30 is tilted in the state before the cable is placed is due to the weight of the cable placed on the placement surface 31 when a plurality of supports are successively connected in the horizontal direction. This is to prevent the support part 30 from tilting downward with the base 10 as a fulcrum and destabilizing the holding of the cable. , each support is maintained in a horizontal straight position.

By the way, the two supports of the above embodiment can be connected by a locking means for locking the locking part and the locked part, and in this embodiment, the locking part 17 is the locking part. The latched portion 33 corresponds to the latched portion. However, when carrying out the present invention, the locking means is not limited to the locking means in which the locking portion 17 of this embodiment locks on the hooked portion 33.

Further, in the support 1 of the above embodiment, after inserting the reinforcing wall 32 into the receiving space 20 by bringing the hooking part 17 close to the reinforcing wall 32 of the other supporting tool 1A from below, as shown in FIG. As shown in , by sliding the hooking portion 17 horizontally toward the base 10 side of the other support 1A and hooking the hooking portion 17 on the hooked portion 33 of the other support 1A, Although it is connected to another support 1A, when carrying out the present invention, before or by sliding the hook part 17 in the horizontal direction, the hook part 17 is connected to the other support member 1A. The reinforcing wall 32 may be inserted into the receiving space 20 and connected after being hooked onto the hooked portion 33 of the support 1A. For example, as shown in FIG. 7, a reinforcing wall 32 that hangs downward is provided on the lower side of the support part 30 near the base 10, and a reinforcing wall 32 that is longer than the reinforcing wall 32 extends horizontally from the lower edge of the reinforcing wall 32. Assuming that a hooked portion 33 is provided, first the hooking portion 17 of the support 1 is hooked to the hooked portion 33 of the other support 1A by horizontal sliding, and then the hooking portion 17 of the support 1 is hooked on the hooked portion 33 of the other support 1A, and then further horizontally slid. By inserting the reinforcing wall 32 of another support 1A into the receiving space 20 of the support 1, the connection may be made.

Although the surface of the bottom wall portion 11 facing the fixing portion 15 at the lower end of the other support 1A in the fixing portion 13 at the upper end in the above embodiment is formed as a flat surface, the present invention is not limited to this. Rather, a recessed surface is formed partially on the bottom wall 11 to expand the gap between the fixing part 13 at the upper end and the fixing part 15 at the lower end of the other support 1A, so that the head 41 of the screw 40 It may be possible to more reliably avoid interference with.

In addition, the head accommodation space of the above embodiment may be formed by the base body or the wiring/piping material receiver and the hanging body, or may be formed by the base body or the wiring/piping material receiver. It may be formed by only a hanging body or only a hanging body.

Furthermore, the fixing portion at the upper end or lower end of each support of the above embodiments has a projecting piece extending laterally to either the left or right or both at the upper end or lower end of the rectangular plate-shaped bottom wall portion 11. , this protruding piece may be provided with a screw insertion hole. In this case, since there is nothing above the fixing part, it is easy to fix the screw 40.

The support 1 of the above embodiment can be attached to the hooked part 33 of the other support 1A from the insertion direction of the screw 40, that is, from the front of the support 1. 1A can be fixed to the wall surface 50 and then additionally connected thereto. Any type of material may be used as long as it can be connected from the front.

In addition, in the above embodiment, two supports are connected and fixed to the wall surface 50, but the present invention can be similarly applied to a case where three or more supports are connected in three or more stages. I can do it.

The support 1 of the above embodiment is provided with the second hooking portion 22 and the second hooked portion 35 in order to be able to connect in the lateral direction, but when implementing the present invention, these are It does not necessarily have to be provided.
