Description

The present invention relates to an installation body supported by a support arm fixed to a structure behind a wall, and an installation body support device equipped with the same.

17, for example, there is a wiring box 100 supported by a support arm 200 of a support fixed to a pillar behind a wall (see Patent Document 1). In this wiring box 100, the support arm 200 is fitted into a recess formed on the back surface, and the screw fixing hole 124 of the hook plate 121 and the horizontally long hole in the middle of the support arm 200 are aligned, so that the box can be fixed with a fixing screw.
However, with this wiring box 100, when using a support arm 200 with a large width (vertical width in the figure) for reasons of strength, thickness, etc., the support arm 200 does not fit into the recess, so it was necessary to prepare multiple wiring boxes 100 with recesses of different widths.

18, there is a support that supports a wiring box B by a slider 4 fitted to a support arm 1b of a support fixed to a pillar behind a wall (see Patent Document 2). This support can be moved along the support arm 1b to change its position.
However, with this support, due to reasons such as strength and thickness, the sliding body 4 cannot be used for support arms 1b having a large width (vertical width in the drawing), which is inconvenient.

Furthermore, for example, as shown in Figure 19, there is a support in which the tip sides of support arms 21, 31 are assembled in a mutually overlapping state, and the length of the support can be changed in accordance with the pitch between the pillars (see Patent Document 3).
However, in this support body, in order to overlap the support arms 21, 31, the vertical width of one support arm 31 is larger than the other support arm 21. Therefore, in order to use the techniques of Patent Documents 1 and 2 with this support body, it is necessary to change the support arms 21, 31 to different sizes at their longitudinal positions, which is troublesome.

According to the invention (arrangement) described in claim 1, the device includes a main body having an aligning portion along which the support arm is placed, a hooking portion provided with a space between the aligning portion and the hooking portion for the support arm to enter, a connecting portion connecting the hooking portion and the main body, and a connecting portion connecting the space to the outside, allowing the support arm to be inserted into the space, and an attachment portion that can be attached to the support arm. The space is provided with an entry restriction portion at the back in the insertion direction of the support arm into the space, which abuts against the inserted support arm to restrict further entry, and the entry restriction portion can be moved to a retracted position that allows the support arm to enter further back than the position where the support arm is restricted, and the movement to the retracted position expands the entry range of the support arm into the space. This ensures an appropriate insertion length according to the width of the support arm in the insertion direction.

According to the invention described in claim 2, in addition to the effect of the invention described in claim 1, the entry restriction portion is formed in multiple stages in the insertion direction, so that the appropriate insertion length of the support arm can be changed in multiple stages.

According to the invention described in claim 3, in addition to the effects of the invention described in claim 1 or 2, the entry restriction part is joined by a joint that breaks when pressed from a direction different from the insertion direction, and can be moved to a position that allows the entry by the breakage, so that the entry can be easily permitted.

According to the invention described in claim 4, in addition to the effects of any of the inventions described in claims 1 to 3, the insertion direction and the expansion direction are the same, so it is possible to intuitively determine which part the support arm should abut in order to expand the back side in the insertion direction.

According to the invention described in claim 5, in addition to the effects of any of the inventions of claims 1 to 4, a mounting hole is formed through which a mounting member is inserted into an insertion portion provided on the support arm to determine the mounting position of the arrangement in the extension direction of the support arm, and the mounting member is screwed into the insertion portion and is screwed into the mounting hole, so there is no need to prepare a separate mounting member. Also, there is no need to align the mounting hole and the mounting member.

According to the invention described in claim 6, in addition to the effects of any of the inventions described in claims 1 to 5, the main body has a peripheral wall consisting of a bottom wall and a side wall erected from the bottom wall, and an opening formed by surrounding the tip side of the side wall, and the space is formed between the peripheral wall and the engaging portion, so that a box-shaped arrangement can be supported by the support arm.

According to the invention described in claim 7, in addition to the effect of the invention described in claim 6, the side wall is the lining portion, and the attachment portion is arranged such that the connecting portion and the communicating portion are positioned opposite each other and the direction of arrangement of the connecting portion and the communicating portion coincides with the direction of opposition between the bottom wall and the opening, so that the position of the opening can be changed in the front-rear direction relative to the support arm installed behind the wall.

According to the invention (arrangement support device) described in claim 8, the support is composed of two types: (1) a support having a relatively narrow support arm and a support having a relatively wide support arm, in which the width of the support arm extending from the fixed part at a constant width is different, or (2) a support arm having a support arm in which the width of the support arm differs midway in the direction of extension from the fixed part, with a portion where a relatively narrow support arm is formed and a portion where a relatively wide support arm is formed, and by abutting the narrow support arm against the entry restriction portion, the relative position of the main body or the entire arrangement with respect to the center of the width direction of the narrow support arm and the relative position of the main body or the entire arrangement with respect to the center of the wide support arm when the entry restriction portion with which the narrow support arm abuts is removed and the wide support arm is inserted into the expanded space expanded beyond the removed entry restriction portion until further entry is restricted, match. As a result, even if the support arms have different widths, the relative position of the main body or the arrangement with respect to the center of the support arm matches, and stable support can be achieved.

According to the invention (support device for an installation body) described in claim 9, the installation body is formed with an attachment hole through which the attachment member passes, and the support body is composed of two types of supports: (1) a support arm having a relatively narrow support arm and a support arm having a relatively wide support arm, the width of which varies from the fixed part at a constant width, or (2) a support arm having a support arm with a portion where a relatively narrow support arm is formed and a portion where a relatively wide support arm is formed, the width of the support arm varying midway in the direction of extension from the fixed part, and the support arm has a portion where a relatively narrow support arm is formed, and the width of the support arm The mounting body can be attached to the support arm by sliding the mounting body relative to the support arm in the direction of insertion into the space. By abutting the narrow support arm against the entry restriction part, the mounting hole and the insertion part provided on the narrow support arm match in position. When the entry restriction part against which the narrow support arm abuts is removed and the wide support arm is inserted into the expanded space that is expanded further back than the removed entry restriction part until further entry is restricted, the mounting hole and the insertion part provided on the wide support arm match in position. This allows the mounting position of the mounting member to match the insertion part of the support arm even if the support arms are different in width.

According to the invention (installation body support device) described in claim 10, when the side of the installation body facing the wall surface is defined as the front, the support body can be fixed to a structure so that its front-to-rear direction is the insertion direction of the support arm into the space, and the position of the opening relative to the end of the support arm facing the wall surface can be changed to a first position determined by the support arm abutting the entry restriction part, and a second position relatively different in the front-to-rear direction from the first position by the support arm entering the expanded area after the entry restriction part is removed. This makes it easy to change the installation position of the installation body in the front-to-rear direction relative to the fixed support arm.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In this embodiment, a wiring box 2A for installing wiring devices such as switches and outlets on a wall surface will be exemplified as an arrangement according to the present invention (see FIG. 1).
As the mounting body, in addition to the wiring box, for example, a pipe clip, a cable holder, a support capable of holding a wiring box, etc. may be used.

First Embodiment
1 and 2, the installation body support device 1 according to this embodiment includes a wiring box 2A arranged behind a wall, and a support body 3 for supporting the wiring box 2A. The wiring box 2A is supported by a support arm 7 of the support body 3 and arranged behind the wall so that it faces the front side of the wall through a wall hole (through hole) 4a formed in the wall 4 (see FIGS. 6 and 7).

1 and 2, the symbol "A" indicates the extension direction (extension direction) of the support arm 7, the symbol "B" indicates the vertical direction perpendicular to the extension direction A of the support arm 7, and the symbol "C" indicates the front-rear direction perpendicular to the extension direction A of the support arm 7. This front-rear direction C refers to the front-rear direction when the side facing the wall surface of the wiring box 2A is defined as the front.

The support 3 has a fixing part 6 that is fixed to a structure (e.g., a steel or wooden pillar) 5 behind the wall, and a support arm 7 that extends from the fixing part 6 so as to be spaced apart from the structure 5. The direction A in which the support arm 7 extends is along the back surface of the wall (horizontal direction). Furthermore, the support arm 7 is provided with an insertion part 8 through which a mounting member 30 is inserted to determine the mounting position of the wiring box 2A in the extension direction A of the support arm 7. The insertion part 8 is formed in the shape of a long hole (or groove) that extends along the extension direction A of the support arm 7, and multiple insertion parts 8 are provided along the extension direction A of the support arm 7. Furthermore, the insertion part 8 is a screw-receiving part into which a screw, which is the mounting member 30, can be screwed.

The insertion portion (threaded portion) 8 does not strictly need to be a female thread as long as the screw can be attached. The insertion portion 8 may be, for example, one or more long holes or long grooves, or even multiple round holes, as long as the wiring box 2A can be attached at multiple different positions in the extension direction A of the support arm 7. Furthermore, the mounting member 30 may be, in addition to a screw, for example, a press-fit member that is press-fitted into the insertion portion 8 or a locking member that is locked to the insertion portion 8.

The supports 3 have different widths of the support arms 7 (width in a direction perpendicular to the extension direction A of the support arms 7) that extend from the fixed portion 6 at a constant width, and include two types: support 3A (see Figure 6) with a relatively narrow support arm 7A, and support 3B (see Figure 7) with a relatively wide support arm 7B.

As the support, for example, as shown in FIG. 16, a support 3C may be used, which has a support arm 7 with a width that varies midway in the extension direction A from the fixed part 6, with a portion where a relatively narrow support arm 7A is formed and a portion where a relatively wide support arm 7B is formed. In this support 3C, the tip sides of the support arms 7A and 7B are assembled in a mutually overlapping state, and the length can be changed in accordance with the pitch between the structures 5. Also, for example, three or more types of supports with different widths may be used as the support. Furthermore, for example, a double-supported or cantilevered support may be used as the support.

As shown in Figs. 3 to 5, the wiring box 2A includes a main body 11 having an alignment portion 10 along which the support arms 7A and 7B are aligned, and an attachment portion 12A that can attach the wiring box 2A to the support arms 7A and 7B. The main body 11 includes a peripheral wall consisting of a bottom wall 14 and a side wall 15 that stands upright from the bottom wall 14, and an opening 16 that faces the bottom wall 14 and is surrounded by the tip side of the side wall 15. The bottom wall 14 is formed with a folding auxiliary hole 17 for removing the attachment portion 12A. The auxiliary hole 17 allows the attachment portion 12A to be removed when the bottom wall 14 is fixed against a wall surface. The bottom wall 14 is also provided with a screw holding portion 18 that holds a screw for fixing a wiring device (not shown). The side wall 15 is also formed with a cable insertion hole 19. The upper and lower edge end faces of the opening 16 are also formed with device mounting portions 20 for attaching the wiring device. Furthermore, a recess 21 is formed in the center of the tip of the left and right side walls 15 to hook the tip of a tool inserted through the wall hole 4a when sliding the wiring box 2A supported by the support arms 7A and 7B.

The attachment portion 12A has an engagement portion 23 provided with a space 24 between it and the lining portion 10 into which the support arms 7A and 7B enter, a connecting portion 27 connecting the engagement portion 23 to the main body 11, and a communication portion 25 connecting the space 24 to the outside, which allows the support arms 7A and 7B to be inserted by relatively sliding the support arms 7A and 7B toward the space 24 while keeping them aligned along the outer surface along which the support arms 7A and 7B are aligned, and is generally L-shaped. The space 24 is formed between the bottom wall 14 of the main body 11 and the engagement portion 23. The connection portion 27 is provided opposite the communication portion 25. The attachment portion 12A is provided in a plurality (two in the figure) on the bottom wall 14 of the main body 11 in line with the extension direction A of the support arms 7A and 7B. Specifically, the attachment portions 12A are disposed on both sides of the bottom wall 14 of the main body 11 in the extending direction A of the support arms 7A, 7B, sandwiching a mounting hole 31 described below.
It should be noted that instead of multiple attachment parts, only a single attachment part 12A may be provided.

In the space 24 of the attachment portion 12A, an entry restriction portion 26 is provided at the back in the insertion direction F of the support arms 7A and 7B into the space 24, which abuts against the end edge of the inserted support arms 7A and 7B at the insertion tip side to restrict further entry. This entry restriction portion 26 can be moved (specifically, can be removed) to a retracted position E that allows the support arms 7A and 7B to enter further back than the position where the support arms 7A and 7B are restricted (see FIG. 8). By moving to the retracted position E, the entry range of the support arms 7A and 7B into the space 24 is expanded, and the support arms 7A and 7B can be inserted into the expanded space 24. The insertion direction F of the support arms 7A and 7B and the expansion direction of the space 24 are the same. Furthermore, the connecting portion 27 of the attachment portion 12A restricts the entry of the support arms 7A and 7B at the innermost point in the insertion direction F, where the support arms 7A and 7B abut when the entry range of the support arms 7A and 7B is expanded to its maximum.

The entry restriction portion 26 is joined to the engagement portion 23 by a joint 28 that breaks when pressed from a direction different from the insertion direction F of the support arms 7A and 7B (for example, breaks due to pressing, or breaks due to fatigue caused by rotational movement) (see Figures 3 and 5(c)). The breakage of this joint 28 allows movement to a retracted position E that allows entry. The joint 28 is also formed with a smaller thickness than other parts of the engagement portion 23 so that it can be easily broken. The joint 28 is also located in the middle of the left and right side walls of the entry restriction portion 26 in the vertical direction. The entry restriction portion 26 is also formed with a recess into which a tool can be inserted and engaged when removing the entry restriction portion 26.

As an entry restriction section, for example, as shown in FIG. 9, an entry restriction section 26 may be used in which the joint section 28 is deformed or partially broken so as not to be separated from the attachment section 12A, and which moves to a retracted position E that allows the support arm 7 to enter the expanded space 24. Furthermore, as an entry restriction section, for example, a section formed on the connecting section 27 or the bottom wall 14 of the main body 11 may be used.

The wiring box 2C (specifically, the bottom wall 14 of the main body 11) has a mounting hole 31 through which the mounting member 30 inserted into the insertion portion 8 of the support arms 7A, 7B passes (see FIG. 6(c)). The inner surface of this mounting hole 31 abuts against the mounting member 30 inserted into the insertion portion 8, restricting movement of the wiring box 2A itself in the direction B (up and down direction) perpendicular to the extension direction A of the support arms 7A, 7B. Specifically, the mounting hole 31 is a round hole that does not extend in the direction B perpendicular to the extension direction A of the support arms 7A, 7B.
The mounting hole 31 may be formed in the engaging portion 23, for example.

The mounting member (screw) 30 that is screwed into the insertion portion 8 is provisionally screwed into the mounting hole 31 at a position where its tip does not interfere with the insertion of the support arms 7A and 7B into the space 24 (see FIG. 5(b)). In addition, auxiliary holes 32 are connected to both the left and right sides of the mounting hole 31 to change the mounting position of the mounting member 30 in the left-right direction (the direction in which the support arms 7 extend) to avoid the position when the gap in the long hole between the insertion portions 8, 8 of the support arms 7 overlaps with the position of the mounting hole 31 (see FIG. 4).

The mounting member 30 may be shipped in a state where it is firmly screwed into the mounting hole 31, rather than being lightly provisionally screwed in. In this case, it is necessary to loosen the mounting member 30 before screwing it into the insertion portion 8 of the support arms 7A and 7B. The mounting member 30 may also be screwed into a portion of the main body 11 other than the mounting hole 31, or may be temporarily held in the mounting hole 31 or another portion of the main body 11 by being pressed in, clamped, locked, or the like.

Next, the operation of the wiring box 2A and the wiring support device 1 configured as above will be explained. A typical lightweight partition wall is constructed from a pair of upper and lower runners fixed to the ceiling and floor, multiple structures 5 erected between the runners, and walls 4 made of gypsum boards or the like erected so as to sandwich the structures 5.

First, the fixing portion 6 is fixed to the structure 5 behind the wall with a screw or the like, and the supports 3A and 3B are placed between the structures 5 (see Figure 1). The supports 3A and 3B are placed at a height position corresponding to the planned position of the wall hole 4a.

When supporting the wiring box 2A on a narrow support arm 7A, the wiring box is slid (moved up and down) relative to the support arm 7A with the width direction of the support arm 7A being the insertion direction F into the space 24, so that the attachment portion 12A is hooked and supported on the support arm 7A. Then, the wiring box 2A is temporarily held with the entry restriction portion 26 abutting against the edge of the insertion tip side of the support arm 7A (see Figure 6). In this temporarily held state, the mounting hole 31 and the insertion portion 8 of the support arm 7A are aligned. Furthermore, the wiring box 2A can slide along the extension direction A of the support arm 7A.

Next, a wall 4 is erected in front of the structure 5, and a wall hole 4a is drilled in a predetermined position in the wall 4 using a hole saw or the like from the wall surface space. In general, when the wall 4 is erected, the structure 5 slides sideways along the runner, so it is assumed that the position of the opening 16 of the wiring box 2A supported by the support arm 7A and the position of the wall hole 4a will be misaligned in the extension direction A of the support arm 7. In such a case, in order to make the opening 16 face the wall hole 4a, a hand or a tool is inserted through the wall hole 4a to slide the wiring box 2A along the support arm 7A to adjust its position. Then, by operating from the opening 16 through the wall hole 4a, the mounting member 30 provisionally screwed into the mounting hole 31 is screwed into the insertion portion 8 of the support arm 7A, and the wiring box 2A is permanently fixed to the support arm 7A (see FIG. 6).

On the other hand, when the wiring box 2A is supported by the wide support arm 7B, the entrance restricting portion 26 is removed to expand the space 24, and then the wiring box 2A is slid relatively (up and down) with the width direction of the support arm 7B being the insertion direction F into the space 24, so that the attachment portion 12A is hooked and supported by the support arm 7B. Then, the wiring box 2A is temporarily held with the connecting portion 27 abutting against the edge of the support arm 7B on the insertion tip side (see FIG. 7). Thereafter, the wiring box 2A is permanently fixed to the support arm 7B in substantially the same manner as the operation of the wiring box 2A temporarily held by the narrow support arm 7A.
The entry restriction portion 26 may be removed while the attachment portion 12A is hooked onto the support arm 7B.

Here, as shown in Fig. 6, by abutting the narrow support arm 7A against the entry restriction portion 26, the relative position of the main body 11 or the entire wiring box 2A with respect to the center of the width of the narrow support arm 7A coincides with the relative position of the main body 11 or the entire wiring box 2A with respect to the center of the width of the wide support arm 7B when the entry restriction portion 26 with which the narrow support arm 7A abuts is removed and the wide support arm 7B is inserted until further entry is restricted into the expansion space 24 that is expanded further back than the removed entry restriction portion 26. Also, as shown in Fig. 6, by abutting the narrow support arm 7A against the entry restriction portion 26, the positions of the mounting hole 31 and the insertion portion 8 provided on the narrow support arm 7A coincide with each other. Furthermore, as shown in FIG. 7, when the entry restriction portion 26 against which the narrow support arm 7A abuts is removed and the wide support arm 7B is inserted into the expanded space 24 that is expanded further back than the removed entry restriction portion 26 until further entry is restricted, the mounting hole 31 and the insertion portion 8 provided on the wide support arm 7B are aligned.

As described above, the wiring box 2A of this embodiment includes a main body 11 having a lining portion 10 along which the support arms 7A and 7B are aligned, a hooking portion 23 provided between the lining portion 10 and the hooking portion 23 with a space 24 into which the support arms 7A and 7B enter, a connecting portion 27 connecting the hooking portion 23 to the main body 11, and an attachment portion 25 that connects the space 24 to the outside and allows the support arms 7A and 7B to be inserted by relatively sliding the support arms 7A and 7B toward the space 24 while keeping them aligned along the outer surface along which the support arms 7A and 7B are aligned. The space 24 is provided with an entry restriction section 26 that abuts against the edge of the inserted support arms 7A, 7B and restricts further entry at the rear of the space 24 in the insertion direction F of the support arms 7A, 7B, and the entry restriction section 26 can be moved to a retracted position E that allows the support arms 7A, 7B to enter further than the position where the support arms 7A, 7B are restricted. By moving to the retracted position E, the entry range of the support arms 7A, 7B into the space 24 is expanded, and the support arms 7A, 7B can be inserted into the expanded space 24. This ensures an appropriate insertion length according to the width of the support arms 7A, 7B in the insertion direction F.

In addition, in this embodiment, the entry restriction portion 26 is joined by a joint 28 that breaks when pressed from a direction different from the insertion direction F of the support arms 7A and 7B into the space 24, and can be moved to a position E that allows entry by breaking, so that the entry can be easily permitted.

In addition, in this embodiment, the insertion direction F of the support arms 7A and 7B into the space 24 is the same as the expansion direction of the space 24, so it is possible to intuitively determine which part the support arms 7A and 7B should abut in order to expand the back side in the insertion direction F.

In this embodiment, the main body 11 is formed with mounting holes 31 through which mounting members 30 pass, which are inserted into the insertion portions 8 provided on the support arms 7A, 7B to determine the mounting positions of the wiring box 2A in the extension direction A of the support arms 7A, 7B, and the mounting members 30 that are screwed into the insertion portions 8 are screwed into the mounting holes 31, so there is no need to prepare the mounting members 30 separately. Also, there is no need to align the mounting holes 31 and the mounting members 30.
In particular, in this embodiment, the mounting member 30 is provisionally screwed into the mounting hole 31 at a position that is reserved so as not to hinder the insertion of the support arms 7A, 7B into the space 24, so that the mounting member 30 can be screwed in immediately.

In addition, according to the arrangement support device 1 of this embodiment, the support 3 is composed of two types of support arms 7, each of which has a different width, the support arm 7 extending from the fixed portion 6 at a constant width, the support arm 7A being a relatively narrow support arm 7A, and the support arm 3B being a relatively wide support arm 7B. By abutting the relatively narrow support arm 7A against the entry restriction portion 26, the relative position of the main body 11 or the entire wiring box 2A to the widthwise center of the relatively narrow support arm 7A coincides with the relative position of the main body 11 or the entire wiring box 2A to the center of the relatively wide support arm 7B when the entry restriction portion 26 against which the relatively narrow support arm 7A abuts is removed and the relatively wide support arm 7B is inserted into the expanded space 24 expanded deeper than the removed entry restriction portion 26 until further entry is restricted (until it abuts against another entry restriction portion 26 or the connecting portion 27). As a result, even if the support arms 7A, 7B have different widths, the relative positions of the main body 11 or the wiring box 2A to the centers of the support arms 7A, 7B can be aligned and stably supported.
In contrast, if the relatively wide support arm 7B is inserted into the narrow space 24 from which the entry restriction portion 26 has not been removed, it will not be inserted properly and will become unstable.

According to the arrangement support device 1 of the present embodiment, the wiring box 2A has a mounting hole 31 formed in the main body 11 or the engaging portion 23, through which the mounting member 30 passes, and the support body 3 has two types of support arms 7 extending from the fixed portion 6 at a constant width, the support arms 7 having different widths, a support body 3A having a relatively narrow support arm 7A and a support body 3A having a relatively wide support arm 7B, and the wiring box 2A can be attached to the support arms 7A and 7B by sliding the wiring box 2A relatively with the width direction of the support arms 7A and 7B being set as the insertion direction F into the space 24. By abutting the relatively narrow support arm 7A against the entry restriction portion 26, the positions of the mounting hole 31 and the insertion portion 8 provided on the relatively narrow support arm 7A match, and when the entry restriction portion 26 against which the relatively narrow support arm 7A abuts is removed and the relatively wide support arm 7B is inserted into the expansion space 24 expanded further back than the removed entry restriction portion 26 until further entry is restricted (until it abuts against another entry restriction portion 26 or the connecting portion 27), the positions of the mounting hole 31 and the insertion portion 8 provided on the relatively wide support arm 7B match. This makes it possible to align the mounting position of the mounting member 30 with the insertion portions 8 of the support arms 7A and 7B even if the support arms 7A and 7B have different widths.
In contrast, if the relatively wide support arm 7B is inserted into the narrow space 24 from which the entry restriction portion 26 has not been removed, the mounting position of the mounting member 30 will not match with the insertion portion 8 of the support arm 7B due to improper insertion.

In the first embodiment, a configuration in which one entry restriction portion 26 is provided in the insertion direction F of the support arms 7A and 7B into the space 24 is exemplified, but this is not limited thereto. For example, as shown in FIG. 15, a configuration in which multiple stages (two stages in the figure) of entry restriction portions 26 are provided in the insertion direction F of the support arms 7A, 7B, and 7C into the space 26 may be used. According to this configuration, the appropriate insertion length of the support arms 7A, 7B, and 7C can be changed to multiple stages.

Second Embodiment
Next, a second embodiment of the apparatus for supporting an installation body will be described. Components that are substantially the same as those in the apparatus for supporting an installation body of the first embodiment are designated by the same reference numerals and detailed description thereof will be omitted.

As shown in FIG. 10, this wiring support device 1 includes a wiring box 2B that is installed behind a wall and a support body 3 for supporting the wiring box 2B.

The support 3 has two types of support arms 7 that extend from the fixed part 6 at a constant width, each of which has a different width: support 3A has a relatively narrow support arm 7A, and support 3B has a relatively wide support arm 7B.

The wiring box 2A comprises a main body 11 having an alignment portion 10 along which the support arms 7A and 7B are aligned, and an attachment portion 12B that allows the wiring box 2A to be attached to the support arms 7A and 7B. The main body 11 comprises a peripheral wall consisting of a bottom wall 14 and a side wall 15 standing upright from the bottom wall 14, and an opening 16 that faces the bottom wall 14 and is surrounded by the tip side of the side wall 14. The alignment portion 10 is provided on the bottom wall 14.

The attachment portion 12B has an engagement portion 23 provided with a space 24 between it and the lining portion 10 for the support arms 7A and 7B to enter, connecting portions 27 connecting both ends of the engagement portion 23 to the main body 11, and a communication portion 25 that connects the space 24 to the outside, allowing the support arms 7A and 7B to be inserted by relatively sliding them toward the space 24 while keeping them aligned with the outer surface along which the support arms 7A and 7B are aligned. This space 24 is formed between the bottom wall 14 of the main body 11 and the engagement portion 23. Furthermore, the connecting portions 27 are provided opposite each other so as to sandwich the space 24.

The space 24 of the attachment portion 12B is provided with an entry restriction portion 26 that abuts against the edge of the inserted support arms 7A and 7B and restricts further entry, at the back in the insertion direction F of the support arms 7A and 7B into the space 24 (extension direction A of the support arms 7A and 7B). This entry restriction portion 26 can be moved (specifically, can be removed) to a retracted position E that allows the support arms 7A and 7B to enter further back than the position where the support arms 7A and 7B are restricted. By moving to the retracted position E, the entry range of the support arms 7A and 7B into the space 24 is expanded, and the support arms 7A and 7B can be inserted into the expanded space 24. Furthermore, the wiring box 2B (specifically the bottom wall 14 of the main body 11) has an attachment hole 31 through which the attachment member 30 inserted into the insertion portion 8 of the support arms 7A and 7B passes.

Next, the operation of the wiring box 2B and the wiring body support device 1 having the above configuration will be described.
When the wiring box 2B is supported on the narrow support arm 7A, the wiring box 2B is relatively slid from the tip side of the support arm 7A of the cantilevered support 3A with the extension direction A of the support arm 7A being the insertion direction F into the space 24, so that the attachment part 12B is hooked and supported on the support arm 7A. At this time, the wiring box 2B is temporarily held by the entry restriction part 26 abutting against the edge in the width direction of the support arm 7A. Next, the wall 4 is erected on the front side of the structure 5, and the wall hole 4a is drilled at a predetermined position of the wall 4, and then, if necessary, the wiring box 2B is slid along the support arm 7A to adjust the position so that the opening 16 faces the wall hole 4a. Then, the mounting member 30 provisionally screwed into the mounting hole 31 is screwed into the insertion part 8 of the support arm 7A by operating from the opening 16 through the wall hole 4a, and the wiring box 2B is permanently fixed to the support arm 7A.

On the other hand, when supporting the wiring box 2B on the wide support arm 7B, the entry restriction portion 26 is removed to expand the space 24, and then the wiring box 2B is slid relatively from the tip side of the cantilevered support body 3B with the extension direction A of the support arm 7B being the insertion direction F into the space 24, thereby hooking and supporting the attachment portion 12B on the support arm 7B. At this time, the wiring box 2B is temporarily held with the connecting portion 27 abutting against the widthwise edge of the support arm 7B. After that, the wiring box 2B is permanently fixed to the support arm 7B in a manner substantially similar to the action of the wiring box 2B temporarily held on the narrow support arm 7A described above.

Here, by abutting the narrow support arm 7A against the entry restriction portion 26, the relative position of the main body 11 or the entire wiring box 2B with respect to the center of the width of the narrow support arm 7A coincides with the relative position of the main body 11 or the entire wiring box 2B with respect to the center of the width of the wide support arm 7B when the entry restriction portion 26 with which the narrow support arm 7A abuts is removed and the wide support arm 7B is inserted into the expanded space 24 that is expanded deeper than the removed entry restriction portion 26. Also, by abutting the narrow support arm 7A against the entry restriction portion 26, the positions of the mounting hole 31 and the insertion portion 8 provided on the narrow support arm 7A coincide with each other. Furthermore, when the entry restriction portion 26 against which the narrow support arm 7A abuts is removed and the wide support arm 7B is inserted into the expanded space 24 that is expanded further back than the removed entry restriction portion 26, the mounting hole 31 and the insertion portion 8 provided on the wide support arm 7B are aligned.

As described above, the wiring box 2B and the installation support device 1 of this embodiment, in a configuration in which the insertion direction F of the support arms 7A, 7B into the space 24 is the extension direction A of the support arms 7A, 7B, achieves substantially the same effects as the wiring box 2A and the installation support device 1 of the first embodiment.

Third Embodiment
Next, a mounting structure support apparatus according to a third embodiment will be described. Components that are substantially the same as those in the mounting structure support apparatus according to the first embodiment are designated by the same reference numerals and detailed description thereof will be omitted.

As shown in Figures 11 and 12, the installation support device 1 according to this embodiment includes a wiring box 2C that is installed behind a wall and a support body 3 for supporting the wiring box 2C.

The supports 3 have two types of arms 7 that extend from the fixed portion 6 at a constant width, with the arms 7 being different in width: support 3A with a relatively narrow support arm 7A and support 3B with a relatively wide support arm 7B. The supports 3A and 3B are fixed to the structure such that the front-to-rear direction C of the supports 3A and 3B corresponds to the insertion direction F of the support arms 7A and 7B into the space 24 when the side facing the wall surface of the wiring box 2C is defined as the front.

The wiring box 2C comprises a main body 11 having an alignment portion 10 along which the support arms 7A, 7B are aligned, and an attachment portion 12C that allows the wiring box 2C to be attached to the support arms 7A, 7B. The main body 11 comprises a peripheral wall consisting of a bottom wall 14 and a side wall 15 that stands upright from the bottom wall 14, and an opening 16 that faces the bottom wall and is formed by surrounding the tip side of the side wall 14. The alignment portion 10 is provided on the side wall 15.

The attachment portion 12C has an engagement portion 23 provided with a space 24 between it and the lining portion 10 for the support arms 7A and 7B to enter, a connecting portion 27 connecting the engagement portion 23 to the main body 11, and a communication portion 25 connecting the space 24 to the outside, which allows the support arms 7A and 7B to be inserted by relatively sliding them toward the space 24 while keeping them aligned with the outer surface along which the support arms 7A and 7B are aligned, forming a roughly L-shaped plate shape. This space 24 is formed between the side wall 15 of the main body 11 and the engagement portion 23. Furthermore, the connection portion 27 is provided opposite the communication portion 25.

In the space 24 of the attachment part 12C, an entry restriction part 26 is provided at the back in the insertion direction F (front-rear direction C) of the support arms 7A, 7B into the space 24, which abuts against the inserted support arms 7A, 7B to restrict further entry. In addition, in the attachment part 12C, the connecting part 27 and the communicating part 25 are positioned opposite each other, and their arrangement direction coincides with the opposing direction of the bottom wall 14 and the opening 16. Furthermore, the wiring box 2C (specifically, the side wall 15 of the main body 11) has an attachment hole 31 formed therein through which the attachment member 30 inserted into the insertion part 8 of the support arms 7A, 7B passes.

Next, the operation of the wiring box 2C and the wiring body support device 1 having the above configuration will be described.
When the wiring box 2C is supported on a narrow support arm 7A, the wiring box 2C is slid relatively with the front-rear direction C as the insertion direction F into the space 24, so that the attachment part 12C is hooked and supported on the support arm 7A (see FIG. 12(a)). Then, the wiring box 2C is temporarily held in the first position P1 with the entry restriction part 26 abutting against the edge of the insertion tip side of the support arm 7A. This first position P1 is a position where the opening 16 of the wiring box 2C is shifted from the front part 5a by the thickness of the furring strip 33 fixed to the front part 5a facing the wall surface side of the structure 5. Next, the wall 4 is erected on the front side of the structure 5, the wall hole 4a is drilled at a predetermined position of the wall 4, and then the wiring box 2C is slid along the support arm 7A as necessary to adjust the position so that the opening 16 faces the wall hole 4a. Thereafter, the mounting member 30 provisionally screwed into the mounting hole 31 is screwed into the insertion portion 8 of the support arm 7A by operating through the opening 16 via the wall hole 4a, thereby permanently fixing the wiring box 2C to the support arm 7A.

In addition, when the wiring box 2C is supported on a narrow support arm 7A, the entry restriction portion 26 is removed to expand the space 24, and then the wiring box 2C is slid relatively in the front-rear direction C as the insertion direction F into the space 24, so that the attachment portion 12C is hooked and supported on the support arm 7A (see FIG. 12(b)). Then, the wiring box 2C is temporarily held in the second position P2 with the connecting portion 27 abutting the end edge of the insertion tip side of the support arm 7A. This second position P2 is a position where the opening 16 of the wiring box 2C is flush with the front portion 5a facing the front side of the wall of the structure 5 or a position away from the back side of the wall, and is a position shifted from the first position P1 by the thickness of the furring strip material 33. After that, the wiring box 2C is permanently fixed to the support arm 7A in substantially the same manner as the work for the wiring box 2C temporarily held in the first position P1 described above.

On the other hand, when wiring box 2C is supported on a wide support arm 7B, the entry restriction portion 26 is removed to expand the space 24, and then wiring box 2C is slid relatively in the front-to-rear direction C as the insertion direction F into space 24, so that the attachment portion 12C is hooked onto and supported by the support arm 7B (see FIG. 12(c)). Then, wiring box 2C is temporarily held in the first position P1 with the connecting portion 27 abutting against the edge of the support arm 7 on the insertion tip side. After that, wiring box 2A is permanently fixed to support arm 7B in substantially the same manner as the above-mentioned wiring box 2C temporarily held on the narrow support arm 7A.

12(a) and 12(c), by abutting the narrow support arm 7A against the entry restriction portion 26, the relative position of the main body 11 or the entire wiring box 2C with respect to the center of the width of the narrow support arm 7A coincides with the relative position of the main body 11 or the entire wiring box 2C with respect to the center of the width of the wide support arm 7B when the entry restriction portion 26 with which the narrow support arm 7A abuts is removed and the wide support arm 7B is inserted until further entry is restricted into the expansion space 24 that is expanded further back than the removed entry restriction portion 26. Also, by abutting the narrow support arm 7A against the entry restriction portion 26, the positions of the mounting hole 31 and the insertion portion 8 provided on the narrow support arm 7A coincide with each other. Furthermore, when the entry restriction portion 26 against which the narrow support arm 7A abuts is removed and the wide support arm 7B is inserted into the expanded space 24 that is expanded further back than the removed entry restriction portion 26 until further entry is restricted, the mounting hole 31 and the insertion portion 8 provided on the wide support arm 7B are aligned.

As described above, the wiring box 2C and the installation support device 1 of this embodiment provide substantially the same effects as the installation box 2A and the installation support device 1 of the first embodiment, and since the lining portion 10 is the side wall 14 and the attachment portion 12C has the connecting portion 27 and the communicating portion 25 positioned opposite each other and their arrangement direction coincides with the opposing direction of the bottom wall 14 and the opening 16, the position of the opening 16 can be changed in the front-to-rear direction C (the direction moving closer to or away from the back of the wall) with respect to the support arms 7A and 7B installed behind the wall. In other words, it can be used with or without the furring strip 33.

In addition, according to the arrangement support device 1 of this embodiment, the supports 3A and 3B can be fixed to the structure 5 so that the front-rear direction C of the wiring box 2C facing the wall surface is defined as the front, and the position of the opening 16 relative to the end of the support arms 7A and 7B facing the wall surface can be changed to a first position P1 determined by the support arms 7A and 7B abutting the entry restriction portion 26, and a second position P2 that is relatively different from the first position P1 in the front-rear direction C by the support arms 7A and 7B entering the expanded area after the entry restriction portion 26 is removed. This makes it easy to change the mounting position of the wiring box 2C in the front-rear direction C (the direction approaching or moving away from the back of the wall) relative to the fixed support arms 7A and 7B.

Furthermore, in this embodiment, the supports 3A and 3B are fixed to the side of the column 5, which is the structure behind the wall, and the first position P1 is a position where the opening 16 is offset from the front surface 5a of the column 5 by the thickness of the furring strip 33 fixed to the front surface 5a facing the front side of the wall, and the second position P2 is a position where the opening 16 is flush with the front surface 5a of the column 5 facing the front side of the wall or a position away from the back surface of the wall, and is offset from the first position P1 by the thickness of the furring strip 33, so that the opening 16 can be positioned in an appropriate position corresponding to the furring strip 33.

In the third embodiment, the mounting portion 12C is hooked to the support arms 7A and 7B from the front side of the wall, but the present invention is not limited to this. For example, as shown in FIG. 13, the mounting portion 12C may be hooked to the support arms 7A and 7B from the back side of the wall. In this embodiment, the first position P1 when the support arm 7A abuts against the entry restriction portion 26 is a position where the opening 16 of the wiring box 2C is flush with the front portion 5a of the structure 5 facing the front side of the wall or a position away from the back side of the wall, and is a position shifted from the first position P1 by the thickness of the furring strip 33. Furthermore, the second position P2 when the support arm 7A abuts against the connecting portion 27 is a position where the opening 16 of the wiring box 2C is shifted from the front portion 5a by the thickness of the furring strip 33. In other words, the position of the opening 16 can be changed in the front-to-rear direction C relative to the support arms 7A and 7B installed behind the wall, allowing it to be used with or without the furring strip 33.

The present invention is not limited to the above embodiment, and various modifications within the scope of the present invention may be made depending on the purpose and application. In other words, in the above first to third embodiments, the support 3 is provided with a support arm 7 extending in the horizontal direction A, but the present invention is not limited to this. For example, as shown in FIG. 14, a support 3 with a support arm 7 that stands vertically from below may be used. Examples of this form include a form in which an attachment part 12 is provided on the bottom wall 14 of the main body 11, and the position of the wiring box 2 can be adjusted in the horizontal direction B in addition to the vertical direction A (see FIG. 14(a)), and a form in which an attachment part 12 is provided on the side wall 15 of the main body 11, and the position of the wiring box 2 can be adjusted in the direction C approaching and moving away from the wall in addition to the vertical direction A (see FIG. 14(b)).

In addition, in this embodiment, the mounting holes 31 of the mounting body to which the mounting members (screws) 30 are attached are shared for support arms 7 of different widths, but the mounting holes 31 may be provided in different positions for each support arm 7 of each width and may not be shared.

Furthermore, in the above first to third embodiments, a support body 3 having a plate-shaped support arm 7 is exemplified, but this is not limited thereto, and for example, a support body 3 having a screw-shaped or rod-shaped support arm 7 may be used.

In addition, in the above first to third embodiments, a fixing form in which the arrangement (wiring boxes 2A to 2C) and the support arm 7 are connected to each other by the mounting member 30 has been exemplified, but this is not limited to this, and for example, the state in which the arrangement is simply hooked by the support arm 7 may be regarded as the final fixation, and the fixation in which the arrangement and the support arm 7 are connected to each other by the mounting member 30 may be omitted.
Furthermore, for example, when the mounting body is a wiring box 2A to 2C, the mounting member 30 is not inserted (screwed) into the support arm 7, and the opening 16 of the wiring box 2A to 2C is aligned with the position of the wall hole 4a, and the wiring device screwed into the device mounting portion is fixed by clamping the wall 4 between the wiring device and the wiring box 2A to 2C with a screw that secures the wiring device.

This invention is widely used as a technology for supporting a mounting body arranged behind a wall on a support arm in accordance with the width of multiple support arms.

a support body including a fixing portion fixed to a structure behind a wall and a support arm extending from the fixing portion so as to be spaced apart from the structure, the support arm being provided with an insertion portion through which an attachment member for determining an attachment position of the arrangement in the extension direction of the support arm is inserted;
An arrangement support device comprising:
The mounting body has a mounting hole through which the mounting member passes,
The support is
The support arms extending from the fixed portion have different widths, and the support includes two types of support arms, one having a relatively narrow support arm and the other having a relatively wide support arm, or
The width of the support arm varies midway in the direction of extension from the fixed portion, and the support arm has a portion where a relatively narrow support arm is formed and a portion where a relatively wide support arm is formed,
The mounting body can be attached to the support arm by relatively sliding the mounting body with the width direction of the support arm being the insertion direction into the space,
By abutting the narrow support arm against the entry restriction portion, the mounting hole and the insertion portion provided on the narrow support arm are aligned in position,
an insertion hole provided on the wide support arm and an insertion portion provided on the wide support arm are aligned in position when the entry restriction portion against which the narrow support arm abuts is removed and the wide support arm is inserted into an expanded space that is expanded deeper than the removed entry restriction portion until further entry is restricted. The arrangement according to claim 7 ;
A support body including a fixing portion fixed to a structure behind a wall and a support arm extending from the fixing portion so as to be spaced apart from the structure;
An arrangement support device comprising:
The support body can be fixed to the structure such that a front-rear direction of the support body corresponds to an insertion direction of the support arm into the space when a side of the support body facing a wall surface is defined as a front side,
The position of the opening relative to the end of the support arm facing the wall surface is
a first position determined by the support arm abutting against the entry restriction portion;
An arrangement support device characterized in that the first position can be changed to a second position that is relatively different in the fore-and-aft direction by the support arm entering the expanded area after the entry restriction portion is removed.
