As shown in FIGS. 1, 2(c) and 4(e), the hooking portion 17 is provided on each of the pair of side wall portions 12, 12 protruding in a hook shape toward the support portion 30 from the upper end portion of the base portion 10. A pair of flange-shaped latching 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 inner space thereof. A slit-like gap is formed between the pair of hooking pieces 18, 18 of the hooking portion 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 substantially the same size as the plate thickness of 32. A gap 19 between the hooking piece 18 and the bottom wall portion 11 shown in FIG. It is designed to be

Further, a pair of flange-like hooking pieces 21, 21 that are bent like hooks in mutually facing directions protrude from the tip portions of the side wall portions 12 at the intermediate portion of the base portion 10. As shown in FIG. As shown in FIG. 6, the pair of hooking pieces 21, 21 constitute a second hooking portion 22 for connecting the supports 1 together in the horizontal direction. The gap between the pair of latching pieces 21, 21 of the second latching portion 22 for horizontal connection constitutes a receiving space 24 for horizontal connection into which a reinforcing wall 36 for horizontal connection, which will be described later, is fitted.

This prevents the head portion 41 of the screw 40 inserted through the fixing portion 15 at the lower end of the other support 1A from interfering with the fixing portion 13 at the upper end of the support 1 after the two supports are connected. be.

On the other hand, the support portion 30 extends horizontally from the bottom wall portion 11 at a position below the base portion 10 and above the fixing portion 15 at the lower end portion. The support portion 30 is formed in an arc plate shape, and has a mounting surface 31 for supporting the cable. A reinforcing wall 32 is provided below the mounting surface 31 so as to extend downward. Furthermore, the lower end side of the reinforcing wall 32 is provided with a hooked portion 33 that protrudes horizontally and can be hooked by the hooking portion 17 at the upper end. The plate thickness of the hooked portion 33 is formed to be slightly larger than the gap 19 between the hooking piece 18 of the hooking portion 17 and the bottom wall portion 11 , so that the hooked portion 33 can be elastically moved inside the hooking portion 17 . The hooked portion 33 is clamped in the hooking portion 17 so that the two support members are connected vertically.

A vertical wall 34 is formed on the tip 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 portion becomes narrower. The vertical wall 34 is provided with an L-shaped plate-shaped second hooked portion 35 for horizontal connection. The plate thickness is the same as or slightly smaller than that of the stop piece 21 . Furthermore, a rectangular plate-shaped reinforcing wall 36 is provided between the vertical wall 34 and the middle portion in the width direction of the second hooked portion 35, and the plate thickness of the reinforcing wall 36 is It is formed to have substantially the same size as the gap between 21 and 21 .

Next, a method of fixing the supporting member 1 thus formed to the wall surface 50 while vertically connecting it to another supporting member 1A fixed to the wall surface 50 will be described.
As shown in FIG. 3(a), another support 1A is attached to the wall surface 50 by inserting the screws 40 through the screw insertion holes 14 of the fixing portion 13 at the upper end and through the screw insertion holes 16 of the fixing portion 15 at the lower end. Fixed. Therefore, the retaining portion 17 of the supporting tool 1 is placed close to the reinforcing wall 32 of the supporting tool 1A from below, and the reinforcing wall 32 is inserted into the receiving space 20 of the other supporting tool 1A. Next, as shown in FIG. 3B, the hooking portion 17 of the support 1 is horizontally slid toward the base portion 10 side, and the hooked portion 33 is inserted into the inner space of the hooking portion 17 . After insertion, the gap 19 between the hooking piece 18 of the hooking portion 17 and the bottom wall portion 11 is slightly smaller than the plate thickness of the hooked portion 33, so that the hooked portion 33 is separated from the hooking piece 18 and the bottom wall portion. 11, and the ends of the bases 10 of both supports overlap in the direction in which the screws 40 are inserted, that is, in the horizontal left direction from the right direction in FIG. 3(b). After that, by inserting the screw 40 into the screw insertion hole 16 of the fixing portion 15 at the lower end of the support 1 and tightening the screw, the support 1 can be fixed to another part as shown in FIGS. It is fixed to the wall surface 50 while being vertically connected to the support 1A. A connecting device 2 is formed by connecting the support 1 and another support 1A in the vertical direction in this way.

At this time, the fixing portion 13 at the upper end of the support 1A is connected without interfering with the head portion 41 of the screw 40 inserted through the screw insertion hole 16 of the fixing portion 15 at the lower end of the other support 1A. . Since the hooking portion 17 of the support 1 is hooked in a direction close to the wall surface 50, even if the fixing portion 13 at the upper end interferes slightly with the head portion 41 of the screw 40, the fixing portion 15 at the lower end will By fixing it, it can be stably fixed to the wall surface 50 although it is slightly slanted. Therefore, the gap between the fixed portion 13 at the upper end of the support 1 and the fixed portion 15 at the lower end of the other support 1A need not be strictly larger than the height of the head 41 of the screw 40 .

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

Next, the supports can be fixed to the wall surface 50 after connecting a plurality of them in the vertical direction.
As shown in FIG. 5(a), the reinforcing wall 32 of another support 1A is inserted into the receiving space 20 of the support 1A from below, and the hooking portion of the support 1A is inserted. 17 is horizontally slid toward the base portion 10 side of the other support 1A, and the hooked portion 33 of the other support 1A is inserted into the inner space of the hook portion 17. As shown in FIG. After insertion, as shown in FIG. 5(b), the hooked portion 33 of the other support 1A is clamped between the hooking piece 18 of the hooking portion 17 of the support 1 and the bottom wall portion 11. The ends of the base portion 10 of the support are connected to each other in a state of overlapping in the insertion direction of the screw 40 .

At this time, a gap for accommodating the head portion 41 of the screw 40 is formed between the fixing portion 13 at the upper end and the fixing portion 15 at the lower end of the other support 1A. Also, the relative positions of the screw insertion holes of the overlapping fixing portion 13 at the upper end and the fixing portion 15 at the lower end of the other support member 1A match. Therefore, the screw insertion hole 14 of the fixing portion 13 at the upper end of the other support 1A, the fixing portion 13 at the upper end of the support 1 and the fixing portion 15 at the lower end of the other support 1A which overlap and communicate with each other. , and the screw insertion hole 16 of the fixing portion 15 at the lower end of the support 1, screws 40 are inserted 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 action of the support 1 of this embodiment will be described.
The support 1 is screw-fixed to the wall surface 50 so that the fixing portion 13 at the upper end of the support 1A is screwed to the wall surface 50, and the fixing portion 15 at the lower end of the other support 1A is inserted in the direction in which the screw 40 is inserted. In the superimposed state, it can be connected without interfering with the head portion 41 of the screw 40 inserted through the fixing portion 15 at the lower end of the other support 1A. It can be connected to the fixture 1A later and fixed to the wall surface 50 .

Further, the support 1 has fixing portions provided with screw insertion holes at both upper and lower ends of the base portion 10, and the support portion 30 extending from the base portion 10 is positioned above the fixing portion 15 at the lower end. Even after the upper fixing part is fixed to the wall surface 50 and the cable is supported by the supporting part 30, the cable does not interfere with the 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 the screw 40 .

Then, 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 respective screw insertion holes of the fixing portion 13 at the overlapping upper end portion and the fixing portion 15 at the lower end portion of the other supporting member 1A match. Therefore, both screw insertion holes communicate with each other, and the screw 40 can be inserted while being connected to the other support 1A.

Further, the supporting member 1 can be installed simply by inserting the reinforcing wall 32 into the receiving space 20 and sliding the hooking portion 17 of the supporting member 1 toward the base portion 10 with respect to the hooked portion 33 of the other supporting member 1A. can be easily assembled to another support 1A.

By the way, in the above-described embodiment, the connection device 2 that connects two supports in the vertical direction is described, but the support 1 of this embodiment can also be a connection device 3 that connects in the horizontal direction. .

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

Here, as shown in FIG. 6, the tip side of the support portion 30 as a whole is slightly lifted 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 inclined in the state before the cables are placed is that the weight of the cables placed on the placement surface 31 when the plurality of support members are sequentially connected in the horizontal direction. This is to prevent the support portion 30 from tilting downward with the base portion 10 as a fulcrum, thereby preventing the holding of the cable from becoming unstable. , each support is maintained in a horizontal, straight position.

By the way, the two supports in the above embodiment can be connected by means of locking means for locking the locking portion and the locked portion. , and the hooked portion 33 corresponds to the hooked portion. However, when implementing the present invention, the locking means is not limited to the locking means for locking the locking portion 17 to the locked portion 33 of the present embodiment.

In addition, the supporting device 1 of the above-described embodiment is arranged so that the retaining part 17 is brought close to the reinforcing wall 32 of the other supporting device 1A from below and the reinforcing wall 32 is inserted into the receiving space 20, and then, as shown in FIG. As shown in , by sliding the hooking portion 17 in the horizontal direction toward the base portion 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 hooking portion 17 in the horizontal direction, the hooking portion 17 is attached to the other support. The reinforcing wall 32 may be inserted into the receiving space 20 for connection after being hooked on the hooked portion 33 of the support 1A. For example, as shown in FIG. 7, a reinforcing wall 32 hanging downward is provided on the lower portion of the supporting portion 30 near the base portion 10 side, and the lower end edge of the reinforcing wall 32 extends longer than the reinforcing wall 32 in the horizontal direction. Assuming that the hooked portion 33 is provided, the hooking portion 17 of the support 1 is first hooked to the hooked portion 33 of the other support 1A by sliding in the horizontal direction, and then the hooked portion 33 is further slid in the horizontal direction. By inserting the reinforcing wall 32 of the other support 1A into the receiving space 20 of the support 1, the connection may be made.

In addition, the surface of the bottom wall portion 11 facing the fixing portion 15 of the lower end portion of the other support 1A in the fixing portion 13 of the upper end portion of the above-described embodiment is formed to be a flat surface, but it is limited to this. Instead, a recessed surface is partially formed in the bottom wall portion 11, the gap between the fixing portion 13 at the upper end portion and the fixing portion 15 at the lower end portion of the other support 1A is expanded, and the head portion 41 of the screw 40 You may enable it to avoid interference with more reliably.

In addition, the head accommodation space of the above embodiment may be formed by the base body or the wiring/piping material receiving tool and the hanging body in cooperation with each other, or the base body or the wiring/piping material receiving tool It may be formed only by the sole or by the hanging body only.

Further, the fixing portion of the upper end or lower end of each support in the above-described embodiment has a projecting piece extending laterally to one or both of the left and right sides of the upper end or lower end of the rectangular plate-shaped bottom wall portion 11. Alternatively, the projecting piece may be provided with a screw insertion hole. In this case, since there is nothing above the fixing portion, it is easy to fix the screw 40 .

Further, the support 1 of the above-described embodiment is configured such that the hooking portion 17 is hooked to the hooked portion 33 of another support 1A from the direction in which the screw 40 is inserted, that is, from the front of the support 1, so that the other support 1A can be attached to the other support. 1A can be fixed to the wall surface 50 and then additionally connected to it. Anything can be used as long as it can be connected from the front.
