[0002] 17, for example, there is a conventional wiring box 100 that is supported by a support arm 202 of a bracket 200 that is fixed to a pillar P behind a wall (see Patent Document 1). With this wiring box 100, if the position of the box is misaligned with a wall hole formed in the wall, the box can be fixed by loosening the fixing screw 124 from the wall hole, sliding the box along the support arm 202 to adjust the position relative to the wall hole, and then screwing the fixing screw 124 back into the elongated hole 202a of the support arm 202.

[Effects of the Invention]

[0007] According to the invention (support device for an installation body) of claim 1, the installation body includes a hook portion that is hooked and supported on the support arm with its front surface facing the wall, and a position adjustment elongated hole through which an elongated attachment screw extending in a direction perpendicular to the extension direction of the support arm is inserted so that the installation body can be attached to the support arm by an attachment screw screwed into the support arm at a second position obtained by moving the installation body from the first position where it is hooked by the hook portion in a direction perpendicular to the extension direction of the support arm. This allows the installation body to be supported on the support arm by changing between different first and second positions in the direction perpendicular to the extension direction of the support arm. Furthermore, the second position can be selected anywhere within the range of the position adjustment elongated hole through which the attachment screw is inserted.

[0008] Also, claims 1, 6, and 7 According to the invention described in ,beforeThe above-mentioned arrangement has a rotation prevention member mounting portion for mounting a rotation prevention member that prevents the arrangement itself from rotating around the attachment screw inserted into the position adjustment long hole, so that rotation of the arrangement attached to any second position within the range of the position adjustment long hole around the attachment screw can be prevented.

[0009] In addition, claims 1 and 7 According to the arrangement body support device described in ,before The anti-rotation member mounting portion can be mounted from the front side by selecting a different position offset in the extension direction of the position adjustment long hole, thereby preventing rotation of the mounting body mounted at any second position within the range of the position adjustment long hole around the mounting screw.

[0010] Claims 2 and 8 According to the invention described in especially, The mounting body has a first position mounting hole at a position that matches the screw-receiving portion of the support arm to which the mounting screw can be screwed at the first position, separate from the position adjustment slot. The first position mounting hole abuts the mounting screw threaded into the screw-receiving portion and restricts movement of the mounting body itself in a direction perpendicular to the extension direction of the support arm. Therefore, simply hooking the hook portion aligns the screw-in position of the mounting screw, making it easy to screw in the mounting screw. Furthermore, the hook portion prevents rotation of the mounting body itself, even with a single screw, eliminating the need for a rotation prevention mechanism. Furthermore, when the mounting body is not misaligned in the direction perpendicular to the extension direction relative to the wall hole, the first position mounting hole allows mounting while restricting movement in the perpendicular direction. However, when the mounting body is misaligned in the direction perpendicular to the extension direction relative to the wall hole, the position adjustment slot allows for adjustment of the position in the perpendicular direction before mounting.

[0011] Claim 3 According to the invention described in Claim 2In addition to the effects of the invention described above, the attachment screw is temporarily screwed into the first position attachment hole with its tip not protruding too much to prevent it from interfering with the hooking portion when hooking onto the support arm, so there is no need to prepare a separate screw. Also, there is no need to align the attachment screw with the first position attachment hole. Furthermore, the attachment screw can be immediately screwed into the threaded portion of the support arm.

[0012] Claim 4 According to the invention described in especially, The hooking portion has an opening that allows entry into the internal space from a direction perpendicular to the direction in which the support arm extends, and an entry restriction portion that is located deep within the internal space and abuts the support arm to restrict further entry, so it is possible to hook it onto the support arm from a point close to the attachment position to the support arm.

[0013] Claim 4 According to the invention described in especially, In order to change the amount of penetration of the support arm, another penetration restriction portion is provided in the internal space at one or more positions shifted in the penetration direction, and at least the penetration restriction portion located on the front side of the internal space among the another penetration restriction portions is removable, so that removing the penetration restriction portion located on the front side of the internal space allows movement of the support arm to the removed side. Thus, the support arm can support the arrangement by changing between a first position and a second position shifted from the first position in the penetration direction of the support arm into the internal space.

[0014] Claim 5 According to the invention described in claims 1 to 4In addition to the effects of any one of the above inventions, the hook portion allows the support arm to be inserted inward from the tip side in the direction of extension, and can hook onto the support arm inserted inward, and an orthogonal direction movement regulating portion is provided on the inside, on both sides or one side in the orthogonal direction, that abuts to regulate movement in a direction orthogonal to the direction of extension of the inserted support arm, and at least one of the orthogonal direction movement regulating portions provided on both sides or the orthogonal direction movement regulating portion provided on one side is removable, and by removing it, the internal space is expanded to allow movement of the support arm to the side from which it was removed, so that in a configuration in which the hook portion is inserted from the tip side in the direction of extension of the support arm, the arrangement can be supported on the support arm by changing to different first and second positions in the direction orthogonal to the direction of extension of the support arm.

[0015] Claims 7 and 8 According to the invention (arrangement) described in the above, the apparatus comprises a main body having a front surface, and a hook portion that is hooked and supported by the support arm in a state where the front surface faces the wall surface, the hook portion has an internal space where the support arm can be arranged between the main body and the hook portion, an opening that allows entry into the internal space from a direction perpendicular to the direction in which the support arm extends, and an entry restriction portion that is located deep inside the internal space and abuts against the support arm to restrict further entry, and the main body has a first position where the support arm is hooked by the hook portion and abuts against the entry restriction portion. At a second position where the entry restriction portion is moved in a direction away from the support arm, a position adjustment slot is provided through which an attachment screw threaded into the support arm can be inserted, so that when the hook portion is inserted in a direction perpendicular to the extension direction of the support arm, the attachment can be supported on the support arm by changing between different first and second positions in the direction perpendicular to the extension direction of the support arm. Furthermore, the second position can be selected anywhere within the range of the position adjustment slot through which the attachment screw is inserted.

[0016] Claim 9According to the invention (arrangement) described in the above, the arrangement comprises a main body having a front surface, and a hook portion that is hooked onto and supported by the support arm with the front surface facing the wall. The hook portion has an internal space in which the support arm can be placed between it and the main body, an opening that allows the support arm to enter the internal space, and an orthogonal direction movement regulating portion that is located in the internal space and abuts to regulate movement of the entered support arm in a direction perpendicular to the direction of extension. The orthogonal direction movement regulating portion is provided on both sides or one side in the orthogonal direction, and at least one of the orthogonal direction movement regulating portions provided on both sides or the orthogonal direction movement regulating portion provided on one side can be removed by operating from the front side, and the removal expands the internal space to allow movement of the support arm to the removed side. Furthermore, a second orthogonal direction movement regulating portion is formed at the back of the expanded space, which abuts against the support arm that has moved into the space to regulate further movement, so that the arrangement can be supported on the support arm by changing to different first and second positions in the direction perpendicular to the extension direction of the support arm.

[0018] An embodiment of the present invention will be described below 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 is exemplified as an arrangement body according to the present invention (see FIG. 1). Furthermore, a support body according to the present invention is a support body 3 in which the tip ends of support arms 7 are assembled together so as to overlap each other, and the length of which can be changed in accordance with the pitch between structures 5 (see FIG. 12).

[0019] In addition to the wiring box, examples of the arrangement body include a pipe clip, a cable holder, a support body capable of holding a wiring box, etc. In addition to a double-supported support body, a cantilevered support body may also be used as the support body.

[0020] First Embodiment As shown in FIGS. 1 and 2, the installation support device 1 according to this embodiment includes a wiring box 2A disposed behind a wall and a support body 3 for supporting the wiring box 2A. The wiring box 2A is disposed behind the wall so as to face the front side of the wall through a wall hole (through-hole) 4a formed in the wall 4 (see FIG. 6). The support body 3 also includes a fixing portion 6 fixed to a structure 5 behind the wall (e.g., a steel pillar) and a support arm 7 extending from the fixing portion 6 so as to be spaced apart from the structure 5. The extension direction A of the support arm 7 is along the rear surface of the wall (horizontal). The support arm 7 also includes a screw-receiving portion 8 to which a mounting screw 30 (described later) can be attached. The screw-receiving portion 8 is formed in the shape of an elongated hole (or groove) extending in the extension direction A of the support arm 7, and multiple screw-receiving portions 8 are provided along the extension direction A of the support arm 7.

[0021] 1 and 2, the symbol "B" indicates a vertical direction perpendicular to the extending direction A of the support arm 7, and the symbol "C" indicates a front-to-rear direction perpendicular to the extending direction A of the support arm 7. This front-to-rear direction C refers to the front-to-rear direction when the side of the wiring box 2A facing the wall surface is defined as the front.

[0022] As shown in FIGS. 3 to 5 , the wiring box 2A includes a main body 11 having a front surface 11a facing the wall surface, and a hook portion 12A supported by the support arm 7 with the front surface 11a of the main body 11 facing the wall surface. The main body 11 includes a bottom wall 14, a peripheral wall 15 formed of side walls extending upright from the bottom wall 14, and an opening 16 formed opposite the bottom wall 14 and surrounded by the distal end of the peripheral wall 15. The bottom wall 14 is formed with a break-off auxiliary hole 17 for removing the hook portion 12A. The auxiliary hole 17 allows the hook portion 12A to be removed when the bottom wall 14 is secured to the wall surface. The bottom wall 14 is also provided with a screw holding portion 18 for holding a screw for securing a wiring device (not shown). The peripheral wall 15 is also formed with a cable insertion hole 19. Furthermore, device mounting portions 20 for attaching a wiring device are formed on the upper and lower edge surfaces of the opening 16. Furthermore, a recess 21 is formed at the center of the tip of the left and right side walls that make up the peripheral wall 15 to hook the tip of a tool that is inserted through the wall hole 4a when sliding the wiring box 2A supported by the support arm 7.

[0023] The hook portion 12A has an internal space 24 between itself and the bottom wall 14 of the main body 11, in which the support arm 7 can be placed, an opening 25 that allows the support arm 7 to enter (move) relative to the internal space 24 from a direction B (vertical direction) perpendicular to the direction A in which the support arm 7 extends, and an entry restriction portion 26 that is located deep within the internal space 24 and abuts against the edge of the support arm 7 at the tip end in the insertion direction to restrict further entry of the support arm 7, and is generally L-shaped. At the end of the hook portion 12A, a connecting portion 27 that connects to the bottom wall 14 of the main body 11 is provided further back than the entry restriction portion 26 and facing the opening 25. A plurality of hook portions 12A (two in the figure) are provided on the bottom wall 14 of the main body 11, lined up in the extension direction A of the support arm 7. Specifically, the hook portions 12A are disposed on the bottom wall 14 of the main body 11 on both sides in the extending direction A of the support arm 7, with a first position attachment hole 31 (described later) interposed therebetween. It should be noted that instead of a plurality of hook portions 12A, only a single hook portion 12A may be provided.

[0024] The entry restriction portion 26 is formed in a box shape with an open front. The entry restriction portion 26 can be removed by operation from the front surface 11a side (opening 16) of the main body 11. Specifically, the entry restriction portion 26 is joined to the hook portion 12A by a joint 28 that breaks when operated from the front surface 11a side of the main body 11 (for example, by breaking due to pressure or fatigue breakage due to rotational movement). The joint 28 is formed to have a thickness smaller than that of other parts of the hook portion 12A so that it can be easily broken. The joint 28 is also located in the vertical middle of the left and right side walls of the entry restriction portion 26. When the joint 28 breaks, the entry restriction portion 26 is removed from the hook portion 12A, and the internal space 24 expands to allow movement of the support arm 7 toward the removed side (see FIGS. 9(a) and 9(b)).

[0025] In addition, the entry restriction portion 26 may be configured, for example, so that the joint portion 28 is deformed or partially broken so as not to be separated from the hook portion 12A, but to move to a retracted position that allows the support arm 7 to enter the expanded internal space 24.

[0026] As shown in Fig. 6, the wiring box 2A is hooked onto the support arm 7 by the hook portion 12A, and is temporarily held in a first position (normal position) P1 where the support arm 7 abuts against the access restriction portion 26. As shown in Fig. 7, the wiring box 2A is positioned at a second position P2 by moving the access restriction portion 26 in a direction (upward) away from the support arm 7 relative to the first position P1. Furthermore, as shown in Fig. 8, the wiring box 2A is positioned at a different second position P2 in the expanded internal space 24 by removing the access restriction portion 26 and moving the connecting portion 27 of the hook portion 12A in a direction (downward) where it abuts or approaches the support arm 7 relative to the first position P1.

[0027] 4 and 5(b), the wiring box 2A (specifically, the bottom wall 14 of the main body 11) is provided with a first position attachment hole 31 for threading an attachment screw 30 into the threaded portion 8, at a position that coincides with the threaded portion 8 of the support arm 7 at the first position P1 and that is separate from the position adjustment elongated holes 34a and 34b described below. The inner surface of this first position attachment hole 31 abuts against the attachment screw 30 threaded into the threaded portion 8, thereby restricting movement of the wiring box 2A itself in a direction (up-down direction) B perpendicular to the extension direction A of the support arm 7. Specifically, the first position attachment hole 31 is a circular hole that does not extend in the direction (up-down direction) B perpendicular to the extension direction A of the support arm 7.

[0028] As shown in Figure 5(b), the mounting screw 30 is provisionally screwed into the first position mounting hole 31 with its tip not protruding too much so as to prevent it from interfering with the hooking portion 12A when it is hooked onto the support arm 7. In addition, auxiliary holes 32 are connected to both the left and right sides of the first position mounting hole 31 to change the screwing position of the mounting screw 30 in the left-right direction (the direction in which the support arm 7 extends) so as to avoid the position when the gap in the elongated hole between the threaded portions 8, 8 of the support arm 7 overlaps with the position of the first position mounting hole 31 (see Figure 4).

[0029] Note that the mounting screws 30 may be shipped firmly screwed into the first position mounting holes 31, rather than being loosely threaded temporarily. In this case, the mounting screws 30 must be loosened and then screwed into the threaded portions 8 of the support arms 7. The mounting screws 30 may also be threaded into a different portion of the first position mounting holes 31 on the main body 11, or may be temporarily held in the first position mounting holes 31 or in a different portion of the first position mounting holes 31 on the main body 11 by press-fitting, clamping, locking, or the like.

[0030] 3 and 5, the wiring box 2A (specifically, the bottom wall 14 of the main body 11) is provided with position adjustment elongated holes (position adjustment attachment holes) 34a, 34b that extend in a direction (vertical direction) B perpendicular to the extension direction A of the support arms 7 and through which elongated attachment screws 30 can be inserted so that the wiring box 2A can be attached to the support arms 7 with the front surface 11a of the main body 11 facing the wall surface by using attachment screws 30 that are screwed into the threaded portions 8 of the support arms 7. First position attachment holes 31 are located at the ends of the extension directions of the position adjustment elongated holes 34a, 34b. In other words, the position adjustment elongated holes 34a, 34b and the first position attachment hole 31 are offset only in the direction (vertical direction) B perpendicular to the extension direction A of the support arms 7. This improves workability because, when position adjustment in the extension direction A of the support arm 7 is not required, the same position is determined as the screwed portion 8 and only the direction perpendicular to the extension direction A of the support arm 7 needs to be adjusted.

[0031] The wiring box 2A is provided with anti-rotation member mounting portions 37a, 37b for mounting an anti-rotation member 36 (specifically, a screw 36 that can be screwed into the threaded portion 8 of the support arm 7) that prevents the wiring box 2A itself from rotating around the attachment screw 30 inserted through the position adjustment elongated holes 34a, 34b. Of these anti-rotation member mounting portions 37a, 37b, mounting portion 37a is provided on the bottom wall 14 of the main body 11, and mounting portion 37b is provided on the hook portion 12A.

[0032] The anti-rotation member mounting portions 37a, 37b can be positioned at different positions offset in the extension direction of the position adjustment slots 34a, 34b, allowing the anti-rotation member 36 to be attached from the front surface 11a of the main body 11. Specifically, the anti-rotation member mounting portions 37a, 37b are elongated holes extending in the extension direction of the position adjustment slots 34a, 34b. The anti-rotation member 36 attached to the anti-rotation member mounting portions 37a, 37b engages with the support arm 7, thereby preventing rotation of the wiring box 2A itself. Specifically, the screw 36 shown by the solid line in FIG. 7 is inserted into the anti-rotation member mounting portion 37a and threaded into the threaded portion 8 of the support arm 7, thereby preventing rotation of the wiring box 2A itself. The screw 36 shown by the phantom line in FIG. 7 is threaded into the anti-rotation member mounting portion 37b, causing the head and shaft of the screw 36 to abut against the edge of the support arm 7, thereby preventing rotation of the wiring box 2A itself. Furthermore, the rotation prevention member attachment portions 37a, 37b are arranged on both sides of the position adjustment slots 34a, 34b in the extending direction A of the support arm 7.

[0033] The anti-rotation members may be, for example, press-fit members that are press-fit into anti-rotation member mounting portions 37a, 37b or locking members that are locked in place. Furthermore, the anti-rotation member mounting portions may be, for example, through holes that are scattered at multiple positions offset in the extension direction of position adjustment elongated holes 34a, 34b.

[0034] Next, we will explain the operation of the above-configured wiring box support device 1 and wiring box 2A. 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 board or the like erected so as to sandwich the structures 5.

[0035] First, the fixing portion 6 is fixed to a structure 5 behind the wall with screws or the like, and the support 3 is positioned between the structure 5 (see FIG. 1). The support 3 is positioned at a height corresponding to the planned location of the wall hole 4a. Next, with the front surface 11a facing the wall, the wiring box 2A is supported by hooking the hook portion 12A from above onto the support arm 7. Then, the wiring box 2A is temporarily held in the first position P1 where the entry restriction portion 26 abuts against the edge of the insertion tip of the support arm 7 and the opening 16 faces the wall hole 4a (see FIG. 6). At this time, the first position attachment hole 31 and the screw-receiving portion 8 of the support arm 7 are aligned. Furthermore, the wiring box 2A is slidable along the extension direction A of the support arm 7 and can move in the direction (upward) in which the entry restriction member 26 moves away from the support arm 7.

[0036] Next, the wall 4 is erected in front of the structure 5, and a hole 4a is drilled in the wall 4 at a predetermined position using a hole saw or the like from the wall surface space. Generally, when the wall 4 is erected, the structure 5 slides laterally along the runner, so it is expected that the position of the opening 16 of the wiring box 2A supported by the support arm 7 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 jig is inserted through the wall hole 4a to open the wiring box 2A. The position is adjusted by sliding it along the support arm 7.

[0037] When the position of opening 16 of wiring box 2A temporarily held in first position P1 matches the position of wall hole 4a, mounting screws 30 temporarily screwed into first position mounting holes 31 are screwed into threaded portions 8 of support arms 7 by operating through opening 16 via wall hole 4a, thereby permanently fixing wiring box 2A to first position P1 relative to support arms 7 (see FIG. 6). At this time, since entry restricting portions 26 abut against support arms 7, wiring box 2A itself is prevented from rotating around mounting screws 30 as its axis.

[0038] On the other hand, if the position of the opening 16 of the wiring box 2A temporarily held in the first position P1 is shifted downward relative to the position of the wall hole 4a, the wiring box 2A is moved from the first position P1, where the support arm 7 abuts the entry restriction portion 26, in a direction (upward) away from the support arm 7, by operating through the wall hole 4a, to a second position P2, where the positions of the opening 16 and the wall hole 4a are aligned (see FIG. 7 ). In this state, the mounting screws 30 temporarily threaded into the first position mounting holes 31 are removed by operating through the opening 16 via the wall hole 4a, and the mounting screws 30 are inserted into the position adjustment elongated holes 34a and screwed into the threaded portions 8 of the support arms 7, thereby finally fixing the wiring box 2A in the second position P2 relative to the support arms 7. Furthermore, the rotation prevention members 36 are attached to the rotation prevention member attachment portions 37a by operating through the opening 16 via the wall hole 4a, thereby preventing the wiring box 2A from rotating.

[0039] 9(a) and 9(b), if the position of opening 16 of wiring box 2A temporarily held in first position P1 is shifted upward relative to the position of wall hole 4a, a hand or a tool is inserted through opening 16 via wall hole 4a to press entry restriction portion 26 rearward, and the pressing force breaks joint 28, separating and removing entry restriction portion 26 from hook portion 12A. This removal expands internal space 24 to allow movement of support arm 7 toward the removed side, and connection portion 27 of hook portion 12A abuts on support arm 7 that has moved into the expanded internal space 24, restricting further movement (see FIG. 8).

[0040] When the position of opening 16 of wiring box 2A and the position of wall hole 4a are aligned in the state where movement is restricted by connecting portion 27, mounting screw 30 temporarily screwed into first position mounting hole 31 can be removed by operating through opening 16 via wall hole 4a, and the mounting screw 30 can then be inserted through position adjustment elongated hole 34b and screwed into threaded portion 8 of support arm 7, finally fixing wiring box 2A to second position P2 relative to support arm 7 (see FIG. 8). With connecting portion 27 of hook portion 12A abutting against support arm 7, wiring box 2A itself is prevented from rotating about mounting screw 30 as an axis when finally fixed.

[0041] On the other hand, when the position of opening 16 of wiring box 2A is shifted downward relative to the position of wall hole 4a while movement is restricted by connecting portion 27, wiring box 2A is moved, by operating through wall hole 4a, by moving connecting portion 27 of hook portion 12A in a direction (upward) away from support arm 7, to position wiring box 2A at second position P2 where the positions of opening 16 and wall hole 4a coincide (see FIG. 10 ). In this state, by operating through opening 16 via wall hole 4a, mounting screw 30 temporarily threaded into first position mounting hole 31 is removed, and then inserted into position adjustment elongated hole 34b and screwed into threaded portion 8 of support arm 7, wiring box 2A is finally fixed at second position P2 relative to support arm 7. Furthermore, by operating through opening 16 via wall hole 4a, rotation prevention member 36 is attached to rotation prevention member attachment portion 37b, thereby preventing rotation of wiring box 2A itself.

[0042] In addition, the deviation between the position of the opening 16 of the wiring box 2A and the position of the wall hole 4a in the direction perpendicular to the extension direction A of the support arm 7 may occur due to factors such as design changes or misidentification of the drilling position of the wall hole 4a or the installation position of the wiring box 3A.

[0043] As described above, according to the wiring box support device 1 and wiring box 2A of this embodiment, the wiring box 2A includes hook portion 12A that is supported on the support arm 7 with its front surface 11a, which is hooked and faces the wall surface, facing the wall surface, and position adjustment elongated holes 34a, 34b through which elongated mounting screws 30 extending in a direction perpendicular to the extension direction A of the support arm 7 are inserted so that the wiring box 2A can be attached to the support arm 7 with its front surface 11a facing the wall surface by mounting screws 30 that are screwed into threaded portions 8 formed on the support arm 7 at a second position P2 obtained by moving the wiring box 2A from the first position P1 hooked by hook portion 12A in a direction perpendicular to the extension direction A of the support arm 7. As a result, the wiring box 2A can be supported on the support arm by being changed to a first position P1 or a second position P2 that are different in the direction perpendicular to the extension direction A of the support arm 7. Furthermore, the second position P2 can be selected at any position within the range of the position adjustment elongated holes 34a, 34b through which the mounting screw 30 is inserted.

[0044] In addition, in this embodiment, the wiring box 2A has anti-rotation member mounting portions 37a, 37b for mounting an anti-rotation member 36 that prevents the wiring box 2A itself from rotating around the mounting screw 30 inserted into the position adjustment long holes 34a, 34b.Therefore, rotation of the wiring box 2A mounted at any second position P2 within the range of the position adjustment long holes 34a, 34b around the mounting screw 30 can be prevented.

[0045] In addition, in this embodiment, the anti-rotation member mounting portions 37a, 37b are elongated holes extending in the direction in which the position adjustment elongated holes 34a, 34b extend, or have through holes scattered at multiple positions offset in the direction in which the position adjustment elongated holes 34a, 34b extend, and the anti-rotation member 36 can be mounted from the front side by selecting a different position offset in the direction in which the position adjustment elongated holes 34a, 34b extend.The mounted anti-rotation member 36 engages with the support arm 7 to prevent rotation, so that rotation of the wiring box 2A mounted at any second position P2 within the range of the position adjustment elongated holes 34a, 34b around the mounting screw 30 as its axis can be prevented.

[0046] Furthermore, in this embodiment, the wiring box 2A has first-position attachment holes 31 for screwing the attachment screws 30 into the screw-receiving portions 8 at a position different from the position adjustment elongated holes 34a, 34b that coincides with the threaded portions 8 onto which the attachment screws 30 of the support arms 7 can be screwed at first position P1, and the inner surfaces of the first-position attachment holes 31 abut against the attachment screws 30 threaded into the threaded portions 8, restricting movement of the wiring box 2A itself in a direction perpendicular to the extension direction A of the support arms 7. Therefore, simply by hooking the hook portions 12A, the screw-in positions of the attachment screws 30 are aligned, and the attachment screws 30 can be easily screwed in. Furthermore, the hook portions 12A prevent the wiring box 2A itself from rotating, even with a single screw 30, eliminating the need for a rotation-stop structure. Furthermore, when the wiring box 2A is not misaligned in a direction perpendicular to the extension direction A relative to the wall hole 4a, it can be attached in a state where movement in the perpendicular direction is restricted by using the first position attachment hole 31, while when the wiring box 2A is misaligned in a direction perpendicular to the extension direction A relative to the wall hole 4a, it can be attached by adjusting its position in the perpendicular direction using the position adjustment long holes 34a, 34b.

[0047] Furthermore, in this embodiment, the attachment screw 30 is provisionally screwed into the first position attachment hole 31 with its tip not protruding too much to prevent it from interfering with the hook portion 12A when hooking onto the support arm 7, so there is no need to prepare a separate screw 30. Also, there is no need to align the attachment screw 30 with the first position attachment hole 31. Furthermore, the attachment screw 30 can be immediately screwed into the threaded portion 8 of the support arm 7.

[0048] Furthermore, in this embodiment, the main body 11 comprises a bottom wall 14, a peripheral wall 15 consisting of side walls erected from the bottom wall 14, and an opening 16 facing the bottom wall and surrounded by the tip side of the peripheral wall 15, and the internal space 24 is formed in a part of the peripheral wall 15 or on the outside of the bottom wall 14, and the operation of attaching the mounting screw 30 and / or the operation of removing the entry restriction portion 26 can be performed from within the opening 16, so that the operation of attaching the mounting screw 30 and / or the operation of removing the entry restriction portion 26 can be easily performed.

[0049] While the first embodiment exemplifies the hook portion 12A having one entry restriction portion 26 in the internal space 24, the present invention is not limited thereto. For example, as shown in FIG. 16( a), the internal space 24 may be provided with one or more additional entry restriction portions 26 at positions offset in the entry direction to change the amount of entry of the support arm 7, and at least one of the additional entry restriction portions 26 located on the front side of the internal space 24 may be removable. In this embodiment, removing the entry restriction portion 26 located on the front side of the internal space 24 expands the internal space 24 to allow movement of the support arm 7 toward the removed portion. Therefore, the wiring box 2A can be supported on the support arm 7 by changing its position between a first position P1 and a second position P2 offset from the first position P1 in the entry direction of the support arm 7 into the internal space 24.

[0050] Furthermore, in the first embodiment, the hook portion 12A is provided with the removable access restriction portion 26, but the present invention is not limited to this, and for example, as shown in Fig. 16(b), the hook portion 12A may not be provided with the removable access restriction portion 26. Even in this embodiment, the wiring box 2A can be positioned at a second position P2 by moving the connecting portion 27 in a direction away from the support arm 7 relative to a first position P1 where the support arm 7 abuts on the connecting portion 27 of the hook portion 12A.

[0051] <Second embodiment> Next, an installation body support device according to a second embodiment will be described, but components that are substantially the same as those in the installation body support device according to the first embodiment will be designated by the same reference numerals and detailed description thereof will be omitted.

[0052] 11, the present installation body 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 wiring box 2B includes a main body 11 having a front surface 11a that faces the wall surface, and a hook portion 12B that is supported by the support arm 7 in a state in which the front surface 11a of the main body 11 that is hooked and faces the wall surface faces the wall surface.

[0053] The hook portion 12B allows the support arm 7 of the cantilevered support body 3 to be inserted inward from the tip side in the direction of extension, and is capable of hooking onto the support arm 7 inserted inward. On the inside, orthogonal direction movement restricting portions 41 are provided on both sides in the direction orthogonal to the extension direction A of the support arm 7, which come into contact with the support arm 7 so as to restrict movement of the inserted support arm 7 in a direction orthogonal to the extension direction A. Specifically, multiple (two in the figure) orthogonal direction movement restricting portions 41 are provided on one side in the direction orthogonal to the extension direction A of the support arm 7, and one orthogonal direction movement restricting portion 41 is provided on the other side. In addition, connecting portions 42 that connect to the bottom wall 14 of the main body 11 are provided on both ends of the hook portion 12B so as to sandwich the inner space 24. It should be noted that one or more orthogonal direction movement restricting portions 41 may be provided on only one side in the direction orthogonal to the extending direction A of the support arm 7, for example.

[0054] The orthogonal direction movement restricting portion 41 has substantially the same configuration as the entry restricting portion 26 of the first embodiment, and can be removed by operating from the front surface 11a side of the main body 11. By removing this orthogonal direction movement restricting portion 41, the inner space 24 is expanded so as to allow movement of the support arm 7 to the removed side.

[0055] The wiring box 2B is hooked onto the support arm 7 by the hook portion 12B and temporarily held at a first position (normal position) P1 where the support arm 7 abuts against the orthogonal direction movement restricting portion 41. Furthermore, the wiring box 2B positioned at the first position P1 can be positioned at a second position P2 by removing the orthogonal direction movement restricting portion 41 and moving the support arm 7 to the side where it was removed.

[0056] The wiring box 2B (specifically, the bottom wall 14 of the main body 11) is provided with first position attachment holes 31 for screwing attachment screws 30 into the screwed portions 8 at positions that coincide with the screwed portions 8 of the support arms 7 at the first position P1 and that are different from the position adjustment elongated holes 34a, 34b described below. Furthermore, the wiring box 2B (specifically, the bottom wall 14 of the main body 11) is provided with position adjustment elongated holes (position adjustment attachment holes) 34a, 34b, each elongated hole extending in a direction perpendicular to the extension direction A of the support arms 7, through which the attachment screws 30 can be inserted, so that the wiring box 2B can be attached to the support arms 7 with the front surfaces 11a of the main body 11 facing the wall surface at the second position P2 by the attachment screws 30 that are screwed into the screwed portions 8 of the support arms 7.

[0057] When the wiring box 2B is temporarily held at the first position P1, if the position of the opening 16 of the wiring box 2B coincides with the position of the wall hole 4a, the mounting screw 30 temporarily screwed into the first position mounting hole 31 is screwed into the threaded portion 8 of the support arm 7 by operating from the opening 16 via the wall hole 4a, thereby permanently fixing the wiring box 2B to the first position P1 relative to the support arm 7.

[0058] On the other hand, if, when the wiring box 2B is temporarily held at the first position P1, the position of the opening 16 of the wiring box 2B and the position of the wall hole 4a are misaligned in a direction perpendicular to the extension direction A of the support arm 7, the perpendicular direction movement restricting portion 41 corresponding to the misalignment direction is removed by operating from the opening 16 via the wall hole 4a, and the support arm 7 is moved to the side from which it was removed to position it at the second position P2, and the mounting screw 30 temporarily screwed into the first position mounting hole 31 is removed, and the mounting screw 30 is inserted into the position adjustment long holes 34a, 34b and screwed into the threaded portion 8 of the support arm 7, thereby finally fixing the wiring box 2B to the second position P2 relative to the support arm 7.

[0059] As described above, the installation body support device 1 of this embodiment achieves substantially the same effects as the installation body support device 1 of the first embodiment, and the hook portion 12B allows the support arm 7 to be inserted inward from the tip side of its extension direction A, and can hook onto the support arm 7 inserted inward, and on the inside, orthogonal direction movement restricting portions 41 are provided on both sides in the orthogonal direction that abut to restrict movement of the inserted support arm 7 in a direction perpendicular to the extension direction A, and the orthogonal direction movement restricting portions 41 are removable, and by removing them, the inner space 24 is expanded so as to allow movement of the support arm 7 to the removed side.Therefore, in a form in which the hook portion 12B is inserted from the tip side of the extension direction A of the support arm 7, the wiring box 2B can be supported on the support arm 7 by changing to different first position P1 and second position P2 in the direction perpendicular to the extension direction A of the support arm 7. Furthermore, the second position P2 can be selected at any position within the range of the position adjustment elongated holes 34a, 34b through which the mounting screw 30 is inserted.

[0060] Furthermore, in this embodiment, the main body 11 comprises a bottom wall 14, a peripheral wall 15 consisting of side walls erected from the bottom wall 14, and an opening 16 facing the bottom wall and surrounded by the tip side of the peripheral wall 15, and the internal space 24 is formed in a part of the peripheral wall 15 or on the outside of the bottom wall 14, and the operation of attaching the mounting screw 30 and / or the operation of removing the orthogonal direction movement restricting portion 41 can be performed from within the opening 16, so that the operation of attaching the mounting screw 30 and / or the operation of removing the orthogonal direction movement restricting portion 41 can be easily performed.

[0061] <Third embodiment> Next, an installation body support device 1 according to a third embodiment will be described, but components that are substantially the same as those in the installation body support device 1 according to the first embodiment will be designated by the same reference numerals and detailed description thereof will be omitted.

[0062] 12, this wiring box support device 1 includes a wiring box 2C that is installed behind a wall, and a support body 3 that supports the wiring box 2C. This wiring box 2C includes a main body 11 having a front surface 11a that faces the wall surface, and a hook portion 12C that is supported by the support arm 7 with the front surface 11a of the main body 11 that is hooked and faces the wall surface facing the wall surface.

[0063] The hook portion 12C has an internal space 24 in which the support arm 7 can be placed between it and the bottom wall 14 of the main body 11, an opening 25 that allows the support arm 7 to enter (move) relatively into the internal space 24, and an orthogonal direction movement restricting portion 45 that is located in the internal space 24 and abuts against the support arm 7 so as to restrict movement in a direction perpendicular to the direction A in which the entered support arm 7 extends.

[0064] The orthogonal movement restricting portions 45 are provided on both sides in the orthogonal direction. These orthogonal movement restricting portions 45 have substantially the same configuration as the entry restricting portion 26 of the first embodiment and can be removed by operating from the front surface 11a side. Upon removal, the internal space 24 is expanded to allow movement of the support arm 7 toward the removed side. Furthermore, a second orthogonal movement restricting portion 46 is formed at the back of the expanded space 24, which abuts against the support arm 7 that has moved into the space 24 to restrict further movement. Furthermore, connecting portions 47 that connect to the bottom wall 14 of the main body 11 are provided at both ends of the hook portion 12C so as to sandwich the internal space 24.

[0065] Note that one or more orthogonal direction movement restricting portions 45 may be provided, for example, on only one side orthogonal to the extension direction A of the support arm 7. Furthermore, one or more orthogonal direction movement restricting portions 46 may be provided, for example, on both sides orthogonal to the extension direction A of the support arm 7.

[0066] The wiring box 2C is hooked onto the support arm 7 by the hook portion 12C and temporarily held at a first position (normal position) P1 where the support arm 7 abuts against the orthogonal direction movement restricting portion 45. Furthermore, by removing the orthogonal direction movement restricting portion 45, the wiring box 2C temporarily held at the first position P1 is positioned at a second position P2 where the support arm 7 abuts against the second orthogonal direction movement restricting portion 46 or the connecting portion 47.

[0067] The wiring box 2C (specifically, the bottom wall 14 of the main body 11) is provided with a first position attachment hole 31 for threading an attachment screw 30 into the threaded portion 8 at a position that coincides with the threaded portion 8 of the support arm 7 at the first position P1 and is different from the second position attachment hole 48 described below. Furthermore, the wiring box 2C (specifically, the bottom wall 14 of the main body 11) is provided with a second position attachment hole 48 through which the attachment screw 30 can be inserted so that the wiring box 2C can be attached to the support arm 7 with the front surface 11a of the main body 11 facing the wall surface by the attachment screw 30 screwed into the threaded portion 8 of the support arm 7. The first position attachment hole 31 and the second position attachment hole 48 are offset only in the direction perpendicular to the extension direction A of the support arm 7. This improves workability because, when position adjustment in the extension direction A of the support arm 7 is not required, the same position is determined as the screwed portion 8 and only the direction perpendicular to the extension direction A of the support arm 7 needs to be adjusted.

[0068] When the wiring box 2C is temporarily held at the first position P1, if the position of the opening 16 of the wiring box 2C coincides with the position of the wall hole 4a, the mounting screw 30 temporarily screwed into the first position mounting hole 31 is screwed into the threaded portion 8 of the support arm 7 by operating from the opening 16 via the wall hole 4a, thereby permanently fixing the wiring box 2C to the first position P1 relative to the support arm 7.

[0069] On the other hand, when the wiring box 2C is temporarily held at the first position P1, if the position of the opening 16 of the wiring box 2C and the position of the wall hole 4a are misaligned in a direction perpendicular to the extension direction A of the support arm 7, the perpendicular direction movement regulating portion 45 corresponding to the misalignment direction is removed by operating from the opening 16 via the wall hole 4a to expand the internal space 24, and the support arm 7 is positioned at the second position P2 where the second perpendicular direction movement regulating portion 46 or the connecting portion 47 abuts the support arm 7, the mounting screw 30 temporarily screwed into the first position mounting hole 31 is removed, and the mounting screw 30 is inserted into the second position mounting hole 48 and screwed into the threaded portion 8 of the support arm 7, thereby finally fixing the wiring box 2C to the second position P2 relative to the support arm 7.

[0070] As described above, the wiring box 2C of this embodiment comprises a main body 11 having a front surface 11a facing the wall surface, and a hook portion 12C that is hooked and supported by the support arm 7 in a state where the front surface 11a faces the wall surface, and the hook portion 12C comprises an internal space 24 in which the support arm 7 can be placed between the main body 11 and the hook portion 12C, an opening 25 that allows the support arm 7 to move relatively into the internal space 24, and an orthogonal direction movement restricting portion 45 that is positioned in the internal space 24 and abuts against the internal space 24 to restrict movement of the inserted support arm 7 in a direction orthogonal to the direction A in which the inserted support arm 7 extends, and the orthogonal direction movement restricting portion 45 is The support arm 7 is provided on both sides of the intersecting direction and can be removed by operating from the front surface 11a (by operating from the wall surface side through the wall hole 4a), and by said removal, the internal space 24 is expanded to allow movement of the support arm 7 to the removed side.Furthermore, at the back of the expanded space 24, a second orthogonal direction movement restricting portion 46 is formed which abuts against the support arm 7 that has moved into the space 24 and restricts further movement, so that the wiring box 2C can be supported on the support arm 7 by gradually changing between different first and second positions P1 and P2 in a direction orthogonal to the extension direction A of the support arm 7.

[0071] Furthermore, in this embodiment, the main body 11 comprises a bottom wall 14, a peripheral wall 15 consisting of side walls erected from the bottom wall 14, and an opening 16 facing the bottom wall and surrounded by the tip side of the peripheral wall 15, and the internal space 24 is formed in a part of the peripheral wall 15 or on the outside of the bottom wall 14, and the operation of attaching the mounting screw 30 and / or the operation of removing the orthogonal direction movement restricting portion 45 can be performed from within the opening 16, so that the operation of attaching the mounting screw 30 and / or the operation of removing the orthogonal direction movement restricting portion 45 can be easily performed.

[0072] In the third embodiment, the specific stepwise position is determined as the second position P2, but the present invention is not limited to this. For example, instead of or in addition to the second position attachment hole 48, an elongated hole extending toward the expanding side of the space 24 and through which the attachment screw 30 can be inserted may be provided. This allows the intermediate stepwise position to be a non-step second position P2.

[0073] Furthermore, in the above third embodiment, a configuration was exemplified in which the hook portion 12C is inserted from the tip side of the extension direction A of the support arm 7 and is equipped with orthogonal direction movement restriction portions 45, 46, but this is not limited to this, and for example, as shown in Figure 16(a), a configuration in which the hook portion 12C is hooked in a direction perpendicular to the extension direction A of the support arm 7 and is equipped with orthogonal direction movement restriction portions 45, 46 may be adopted.

[0074] The present invention is not limited to the above-described embodiments, and various modifications may be made within the scope of the present invention depending on the purpose and application. While the first to third embodiments illustrate the hook portions 12A to 12C provided on the bottom wall 14 of the main body 11, the present invention is not limited thereto. For example, as shown in FIG. 14, a configuration in which the hook portion 12 is provided on a portion of the peripheral wall 15 may be adopted. This configuration allows the position of the wiring box 2 to be adjusted not only in the horizontal direction A but also in a direction C moving toward or away from the wall. In this configuration, the opening of the hook portion 12 may face either the front side or the rear side.

[0075] Furthermore, in the first to third embodiments described above, the support body 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. 15, a support body 3 may be used that has a support arm 6 that stands vertically from below. Examples of this configuration include a configuration in which a hook portion 12 is provided on the bottom wall 14 of the main body 11, allowing the position of the wiring box 2 to be adjusted in the horizontal direction B in addition to the vertical direction A (see Fig. 15(a)), and a configuration in which a hook portion 12 is provided on a part of the peripheral wall 15 of the main body 11, allowing the position of the wiring box 2 to be adjusted in the direction C moving toward or away from the wall in addition to the vertical direction A (see Fig. 15(b)).

[0076] Furthermore, in the above first to third embodiments, the support body 3 is illustrated as having a plate-shaped support arm 7, but this is not limited to this, and for example, a support body having a screw-shaped or rod-shaped support arm may also be used.

[0077] In addition, in the above-described first embodiment, an example was given of a configuration in which the anti-rotation member mounting portions 37a, 37b and the position adjustment elongated holes 34a, 34b are provided exclusively for the purpose, but this is not limited to this. For example, the anti-rotation member mounting portions may also serve as the position adjustment elongated holes.

[0078] Furthermore, in the above third embodiment, a fixing form in which the arrangement body (wiring box 2C) and the support arm 7 are connected to each other with an attachment screw 31 is exemplified, but this is not limited to this, and for example, the state in which they are simply hooked at the first position P1 may be considered as the final fixation, and the fixing in which the arrangement body (wiring box 2C) and the support arm 7 are connected to each other with an attachment screw 31 may be omitted. Furthermore, for example, if the installation body is a wiring box 2C, the attachment screw 31 is not screwed into the support arm 7, but rather the position of the opening 16 of the wiring box 2C and the position of the wall hole 4a are aligned, and the wiring device can be fixed by clamping the wall 4 between the wiring device and the wiring box 2C using a screw that secures the wiring device screwed into the device mounting portion.
