Description

Technical Field

[0001] The present invention relates to a disposed body supported by a support arm fixed to a structure inside a wall and a disposed body support device including the same.

Background Art

[0002] Conventionally, for example, as shown in FIG. 17, there is a wiring box 100 supported by a support arm 200 of a support fixed to a pillar inside 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 position of the screw fixing hole 124 of the hook plate 121 matches the position of the horizontally long hole in the middle of the support arm 200, and it can be fixed with fixing screws. However, in this wiring box 100, when using a support arm 200 having a large width (the width in the vertical direction in the figure) due to reasons such as strength and thickness, the support arm 200 cannot be fitted into the recess, so it is necessary to prepare a plurality of wiring boxes 100 having different recess widths.

[0003] Also, for example, as shown in FIG. 18, there is a support body that supports a wiring box B by a slide body 4 fitted to a support arm 1b of a support fixed to a pillar inside a wall (see Patent Document 2). In this support body, it is possible to change the position along the support arm 1b. However, in this support body, due to reasons such as strength and thickness, the slide body 4 cannot be used for a support arm 1b having a large width (the width in the vertical direction in the figure), which is inconvenient.

[0004] Furthermore, for example, as shown in FIG. 19, there is a support body in which the tip ends of support arms 21 and 31 are assembled in a state of overlapping each other, and the length can be changed corresponding to the pitch between pillars (see Patent Document 3). However, in this support body, in order to overlap the support arms 21 and 31, the vertical width of one support arm 31 is larger than that of the other support arm 21. Therefore, in order to use the technologies of Patent Document 1 and Patent Document 2 for this support body, it is necessary to change to different sizes at the positions in the length direction of the support arms 21 and 31, which is troublesome.

[0006] The present invention has been made in view of the above situation, and an object thereof is to provide a disposed body that can be supported by a support arm corresponding to the widths of a plurality of support arms and a disposed body support device including the same.

Means for Solving the Problems

[0007] The invention according to claim 1 (disposed body) is a disposed body supported by a support arm of a support body including a fixing portion fixed to a structure inside a wall, and a support arm extending from the fixing portion so as to be separated from the structure, the disposed body having a main body having a portion along which the support arm is arranged, an engaging portion provided with a space for the support arm to enter between the engaging portion and the main body, a connecting portion connecting the engaging portion and the main body, and an attaching portion attachable to the support arm having a communication portion communicating the space with the outside so that the support arm can be inserted into the space. In the space, an entry restricting portion is provided 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. The entry restricting portion is movable to a retracted position that allows the support arm to enter further back than the position where the support arm is restricted, and the entry range of the support arm into the space is expanded by the movement to the retracted position. The invention according to claim 2 is characterized in that, in the invention of claim 1, the entry restricting portion is formed in a plurality of stages in the insertion direction. The invention according to claim 3 is the invention according to claim 1 or 2, wherein the access control part is joined by a joint part that breaks by pressing from a direction different from the insertion direction, and is movable to a position allowing the access by the breakage. The invention according to claim 4 is the invention according to any one of claims 1 to 3, wherein the insertion direction and the expansion direction are the same. The invention according to claim 5 is the invention according to any one of claims 1 to 4, wherein a mounting hole is formed through which a mounting member that is inserted into an insertion part provided in the support arm and determines a mounting position of the disposed body in the extending direction of the support arm penetrates, and the mounting member screwed into the insertion part is screwed into the mounting hole. The invention according to claim 6 is the invention according to any one of claims 1 to 5, wherein the main body includes a peripheral wall composed of a bottom wall and a side wall standing from the bottom wall, and an opening formed by surrounding at the tip side of the side wall, and the space is formed between the peripheral wall and the engaging part. The invention according to claim 7 is the invention according to claim 6, wherein the along part is the side wall, and the attaching part is characterized in that the connecting part and the communicating part are in opposing positions, and their arrangement direction coincides with the opposing direction of the bottom wall and the opening. The invention (arrangement body support device) according to claim 8 comprises an arrangement body according to any one of claims 1 to 7, a fixing part fixed to a structure inside a wall, and a support body including a support arm extending from the fixing part so as to be separated from the structure and supporting the arrangement body. The support body consists of two types of support bodies, one having a support arm with a relatively narrow width and the other having a support arm with a relatively wide width, which extend from the fixing part with different widths, or the support arm has a portion where the width of the support arm is different in the middle in the extending direction from the fixing part, and includes a portion where a support arm with a relatively narrow width is formed and a portion where a support arm with a relatively wide width is formed. By bringing the narrow-width support arm into contact with the access restricting part, the relative position of the main body or the entire arrangement body with respect to the center in the width direction of the narrow-width support arm, removing the access restricting part with which the narrow-width support arm is in contact, and inserting the wide-width support arm into an expansion space expanded deeper than the removed access restricting part until further access is restricted, the relative position of the main body or the entire arrangement body with respect to the center of the wide-width support arm coincides. The invention (arrangement body support device) according to claim 9 includes an arrangement body according to any one of claims 1 to 7, a fixing part fixed to a structure inside a wall, and a support arm extending from the fixing part so as to be separated from the structure. The support arm is provided with a support body having an insertion part through which a mounting member for determining a mounting position of the arrangement body in the extending direction of the support arm is inserted. The arrangement body is formed with a mounting hole through which the mounting member penetrates. The support body is composed of two types, a support body having a relatively narrow support arm and a support body having a relatively wide support arm, the widths of the support arms extending from the fixing part being different, or the width of the support arm is different halfway in the extending direction from the fixing part, and the support arm has a location where a relatively narrow support arm is formed and a location where a relatively wide support arm is formed. By relatively sliding the arrangement body in the width direction of the support arm as the insertion direction into the space, the arrangement body can be attached to the support arm. By bringing the narrow support arm into contact with the entry restricting part, the positions of the mounting hole and the insertion part provided in the narrow support arm are aligned. When the entry restricting part with which the narrow support arm is in contact is removed and the wide support arm is inserted into an expanded space expanded deeper than the removed entry restricting part until further entry is restricted, the positions of the mounting hole and the insertion part provided in the wide support arm are aligned. The invention (arrangement body support device) according to claim 10 includes an arrangement body according to claim 7, a fixing part fixed to a structure inside a wall, and a support body including a support arm extending from the fixing part so as to be separated from the structure. The support body can be fixed to the structure such that the front-rear direction thereof becomes the insertion direction of the support arm into the space when the side facing the wall surface side of the arrangement body is defined as the front. The position of the opening with respect to the end of the support arm facing the wall surface side can be changed to a first position determined by the support arm coming into contact with the entry restricting part and a second position relatively different from the first position in the front-rear direction by the support arm entering the tip where the entry restricting part has been removed and expanded.

Effect of the Invention

[0008] According to the invention (arrangement body) described in claim 1, a main body having a portion along which the support arm is placed, an engaging portion provided with a space for the support arm to enter between the portion along which it is placed, a connecting portion connecting the engaging portion and the main body, and a communicating portion that allows the space to communicate with the outside and enables the support arm to be inserted into the space, and an attaching portion attachable to the support arm, and in the space, an entry restricting portion is provided 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 restricting portion is movable 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. Thereby, an appropriate insertion length corresponding to the width in the insertion direction of the support arm can be ensured.

[0009] According to the invention described in claim 2, in addition to the effect of the invention of claim 1, since the entry restricting portion is formed in a plurality of stages in the insertion direction, the appropriate insertion length of the support arm can be changed in a plurality of stages.

[0010] According to the invention described in claim 3, in addition to the effect of the invention of claim 1 or 2, the entry restricting portion is joined by a joining portion that breaks by pressing from a direction different from the insertion direction, and since it is movable to a position that allows the entry by the breakage, it can be easily brought into a state allowing entry.

[0011] According to the invention described in claim 4, in addition to the effect of any one of the inventions of claims 1 to 3, since the insertion direction and the expansion direction are the same, it is possible to intuitively determine which part of the support arm to abut against in order to widen the back side in the insertion direction.

[0012] According to the invention described in claim 5, in addition to the effects of the invention according to any one of claims 1 to 4, a mounting hole through which a mounting member that is inserted into the insertion portion provided in the support arm and determines the mounting position of the disposed body in the extending direction of the support arm of the disposed body penetrates is formed, and the mounting member screwed into the insertion portion is screwed into the mounting hole, so that there is no need to separately prepare the mounting member. Further, alignment between the mounting hole and the mounting member is not required.

[0013] According to the invention described in claim 6, in addition to the effects of the invention according to any one of claims 1 to 5, the main body includes a peripheral wall composed of a bottom wall and side walls standing from the bottom wall, and an opening formed by surrounding at the tip side of the side walls, and since the space is formed between the peripheral wall and the engaging portion, a box-shaped disposed body can be supported by the support arm.

[0014] According to the invention described in claim 7, in addition to the effects of the invention according to claim 6, the along portion is the side wall, and the attaching portion is such that the connecting portion and the communicating portion are in opposing positions and their arrangement direction coincides with the opposing direction of the bottom wall and the opening, so that the position of the opening can be changed in the front-rear direction with respect to the support arm installed on the back of the wall.

[0015] According to the invention (arrangement support device) described in claim 8, the support body consists of two types: (1) a support body having support arms extending from the fixed part with different widths and having a relatively narrow support arm, and a support body having a relatively wide support arm; or (2) having a support arm in which the width of the support arm is different in the extending direction from the fixed part, and having a portion where a relatively narrow support arm is formed and a portion where a relatively wide support arm is formed. By bringing the narrow support arm into contact with the entry restriction portion, the relative position of the main body or the entire arrangement with respect to the center in the width direction of the narrow support arm, removing the entry restriction portion with which the narrow support arm is in contact, and inserting the wide support arm into the expansion space expanded deeper than the removed entry restriction portion until further entry is restricted, the relative position of the main body or the entire arrangement with respect to the center of the wide support arm coincides. Thereby, even with the difference in the width of the support arm, the relative position of the main body or the arrangement with respect to the center of the support arm can be made to coincide and stably supported.

[0016] According to the invention (arrangement support device) described in claim 9, the arrangement has an attachment hole through which the attachment member passes, and the support body consists of two types: (1) a support body having support arms extending from the fixed part with different widths and having a relatively narrow support arm, and a support body having a relatively wide support arm; or (2) having a support arm in which the width of the support arm is different in the extending direction from the fixed part, and having a portion where a relatively narrow support arm is formed and a portion where a relatively wide support arm is formed. By relatively sliding the arrangement with the width direction of the support arm as the insertion direction into the space, the arrangement can be attached to the support arm. By bringing the narrow support arm into contact with the entry restriction portion, the positions of the attachment hole and the insertion portion provided in the narrow support arm coincide. When the entry restriction portion with which the narrow support arm is in contact is removed and the wide support arm is inserted into the expansion space expanded deeper than the removed entry restriction portion until further entry is restricted, the positions of the attachment hole and the insertion portion provided in the wide support arm coincide. Thereby, even with the difference in the width of the support arm, the attachment position of the attachment member with respect to the insertion portion of the support arm can be made to coincide.

[0017] According to the invention (arrangement body support device) described in claim 10, when the front side of the support body facing the wall surface side of the arrangement body is defined as the front, the front-rear direction thereof can be fixed to the structure so as to be the insertion direction of the support arm into the space, and the position of the opening with respect to the end of the support arm facing the wall surface side is the first position determined by the support arm abutting against the entry restricting portion, and the support arm enters the tip where the entry restricting portion is removed and expanded. The first position can be changed to a second position that is relatively different from the first position in the front-rear direction. Thereby, the attachment position of the arrangement body in the front-rear direction can be easily changed with respect to the fixed support arm.

Mode for Carrying Out the Invention

[0019] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In this embodiment, as the installation body according to the present invention, a wiring box 2A for installing wiring devices such as switches and outlets on the wall surface is exemplified (see FIG. 1). In addition, as the installation body, in addition to the wiring box, for example, a pipe clip, a cable holder, a support body capable of holding a wiring box, etc. may be adopted.

[0020] <First Embodiment> As shown in FIGS. 1 and 2, the installation body support device 1 according to this embodiment includes a wiring box 2A disposed on the back side of the wall, and a support body 3 for supporting the wiring box 2A. This wiring box 2A is supported by the support arm 7 of the support body 3 so as to face the wall surface side from the wall hole (through hole) 4a formed in the wall 4, and is disposed on the back side of the wall (see FIGS. 6 and 7).

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

[0022] The support body 3 includes a fixing portion 6 fixed to a structure (for example, a column made of steel plate or wood) 5 on the back side of the wall, and a support arm 7 extending from the fixing portion 6 so as to be separated from the structure 5. The extending direction A of this support arm 7 is a direction along the back surface of the wall (horizontal direction). Further, the support arm 7 is provided with an insertion portion 8 through which a mounting member 30 for determining the mounting position of the wiring box 2A in the extending direction A of the support arm 7 is inserted. This insertion portion 8 is formed in a long hole shape (or groove shape) extending along the extending direction A of the support arm 7, and a plurality of them are provided along the extending direction A of the support arm 7. Further, the insertion portion 8 is a screwed portion to which a screw, which is the mounting member 30, can be screwed.

[0023] Note that the insertion part (the part to be screwed) 8 does not necessarily have to be a female screw when a screw is threaded. Further, as the insertion part 8, for example, as long as the wiring box 2A can be attached at a plurality of different positions in the extending direction A of the support arm 7, for example, one or a plurality of long holes or long grooves may be adopted, or further a plurality of round holes may be adopted. Further, as the attachment member 30, in addition to screws, for example, a press-fitting member press-fitted into the insertion part 8 or a locking member locked to the insertion part 8 may be adopted.

[0024] The support 3 has different widths of the support arms 7 extending from the fixing part 6 with a constant width (width in the direction orthogonal to the extending direction A of the support arm 7), and includes two types: a support 3A (see FIG. 6) having a relatively narrow support arm 7A and a support 3B (see FIG. 7) having a relatively wide support arm 7B.

[0025] Note that as the support, for example, as shown in FIG. 16, in the extending direction A from the fixing part 6, the width of the support arm 7 is different in the middle, and a support 3C having a support arm 7 provided with a portion where a relatively narrow support arm 7A is formed and a portion where a relatively wide support arm 7B is formed may be adopted. This support 3C is assembled in a state where the tip sides of the support arms 7A and 7B overlap each other, and its length can be changed corresponding to the pitch between the structures 5. Further, as the support, for example, three or more types of supports with different widths may be adopted. Further, as the support, for example, a support in a double-supported form or a single-supported form can be adopted.

[0026] As shown in FIGS. 3 to 5, the wiring box 2A includes a main body 11 having a running portion 10 along which the support arms 7A and 7B are arranged, and an attachment portion 12A capable of attaching the wiring box 2A to the support arms 7A and 7B. The main body 11 includes a peripheral wall composed of a bottom wall 14 and side walls 15 erected from the bottom wall 14, and an opening 16 formed at the tip side of the side walls 15 and facing the bottom wall 14. A folding auxiliary hole 17 for removing the attachment portion 12A is formed in the bottom wall 14. By means of this auxiliary hole 17, the attachment portion 12A can be removed when the bottom wall 14 is pressed against the wall surface for fixing. Further, a screw holding portion 18 for holding screws for fixing a wiring device (not shown) is provided on the bottom wall 14. Further, a cable insertion hole 19 is formed in the side wall 15. Further, instrument attachment portions 20 for attaching a wiring device are formed on the edge end surfaces on both the upper and lower sides of the opening 16. Further, recesses 21 for hooking the tip of a tool inserted from the wall hole 4a are formed at the center of the tips of the left and right side walls 15 when the wiring box 2A supported by the support arms 7A and 7B is slid.

[0027] The attachment portion 12A includes an engaging portion 23 provided with a space 24 between it and the running portion 10 for the support arms 7A and 7B to enter, a connecting portion 27 connecting the engaging portion 23 and the main body 11, and a communicating portion 25 that allows the support arms 7A and 7B to be inserted by relatively sliding them in a posture along the outer surface along which the support arms 7A and 7B are arranged with the space 24 communicating with the outside. It has a substantially L-shaped plate form. This space 24 is formed between the bottom wall 14 of the main body 11 and the engaging portion 23. Further, the connecting portion 27 is provided facing the communicating portion 25. Further, a plurality (two in the figure) of attachment portions 12A are provided side by side in the extending direction A of the support arms 7A and 7B on the bottom wall 14 of the main body 11. Specifically, the attachment portions 12A are arranged on both sides of the extending direction A of the support arms 7A and 7B with an attachment hole 31 (described later) sandwiched therebetween on the bottom wall 14 of the main body 11. Note that instead of a plurality of attachment portions, only a single attachment portion 12A may be provided.

[0028] In the space 24 of the attachment portion 12A, an entry restricting portion 26 is provided at the rear in the insertion direction F of the support arms 7A and 7B into the space 24, which abuts against the edges on the insertion tip side of the inserted support arms 7A and 7B to restrict further entry. This entry restricting portion 26 is movable (specifically removable) 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 is the same as the expansion direction of the space 24. Further, the connecting portion 27 of the attachment portion 12A restricts the entry of the support arms 7A and 7B at the rearmost position 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 the maximum.

[0029] The entry restricting portion 26 is joined to the engaging portion 23 by a joining portion 28 that breaks (for example, breaks by pressing, fatigue breaks by rotational movement, etc.) by pressing from a direction different from the insertion direction F of the support arms 7A and 7B (see Figs. 3 and 5(c)). By breaking this joining portion 28, it is movable to the retracted position E that allows entry. Also, the joining portion 28 is formed with a smaller thickness than other parts of the engaging portion 23 so as to be easily broken. Further, the joining portion 28 is disposed at the vertical middle portion of the left and right side walls of the entry restricting portion 26. Furthermore, the entry restricting portion 26 is formed in a recessed shape for inserting and locking a tool when removing it.

[0030] Note that as the entry restricting portion, for example, as shown in Fig. 9, an entry restricting portion 26 may be adopted in which the joining portion 28 is deformed or partially broken and is not separated from the attachment portion 12A, and moves to the retracted position E that allows the support arm 7 to enter the expanded space 24. Further, as the entry restricting portion, for example, those formed on the connecting portion 27 or the bottom wall 14 of the main body 11 may be adopted.

[0031] In the wiring box 2C (specifically, the bottom wall 14 of the main body 11), there is formed a mounting hole 31 through which a mounting member 30 inserted into the insertion portions 8 of the support arms 7A and 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 the movement of the wiring box 2A itself in the direction B (vertical direction) orthogonal to the extending direction A of the support arms 7A and 7B. Specifically, the mounting hole 31 is a round hole that does not extend in the direction B orthogonal to the extending direction A of the support arms 7A and 7B. Note that, as the mounting hole 31, for example, the one formed in the engaging portion 23 may be adopted.

[0032] In the mounting hole 31, a mounting member (screw) 30 screwed into the insertion portion 8 is temporarily screwed at a position where its tip does not hinder the insertion into the space 24 between the support arms 7A and 7B (see Fig. 5(b)). Further, on both the left and right sides of the mounting hole 31, when the break of the long hole between the insertion portions 8, 8 of the support arm 7 overlaps the position of the mounting hole 31, auxiliary holes 32 are connected to change the mounting position of the mounting member 30 in the left - right direction (the direction in which the support arm 7 extends) to avoid that position (see Fig. 4).

[0033] Note that, in the mounting hole 31, for example, the mounting member 30 may be shipped in a state where it is firmly screwed in without being temporarily screwed lightly. In this case, it is necessary to loosen the mounting member 30 and then screw it onto the insertion portions 8 of the support arms 7A and 7B. Further, the mounting member 30 may be screwed to another part of the main body 11, or may be temporarily held by press - fitting, clamping, locking, etc. to the mounting hole 31 or another part of the main body 11.

[0034] Next, the operations of the wiring box 2A and the arrangement - body support device 1 with the above - described configuration will be described. Note that a general lightweight partition wall is constructed from a pair of upper and lower runners fixed to the ceiling and the floor, a plurality of structures 5 erected between the runners, and a wall 4 made of gypsum board or the like erected so as to sandwich the structures 5.

[0035] First, fix a fixing part 6 to the structure 5 inside the wall with screws or the like, and arrange support bodies 3A and 3B between the structures 5 (see Fig. 1). These support bodies 3A and 3B are arranged at a height position corresponding to the planned position of the wall hole 4a.

[0036] When supporting the wiring box 2A on the narrow support arm 7A, by relatively sliding (vertically moving) the wiring box in the insertion direction F into the space 24 with the width direction of the support arm 7A as the insertion direction, the attachment part 12A is hooked and supported on the support arm 7A. Then, the wiring box 2A is temporarily held with the entry restriction part 26 abutting against the edge on the insertion tip side of the support arm 7A (see Fig. 6). In this temporarily held state, the mounting hole 31 and the insertion part 8 of the support arm 7A are aligned. Furthermore, the wiring box 2A is slidable along the extending direction A of the support arm 7A.

[0037] Next, erect the wall 4 on the front surface of the structure 5, and drill a wall hole 4a at a predetermined position of the wall 4 from the wall surface space using a hole saw or the like. Generally, when the wall 4 is erected, the structure 5 slides laterally 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 are displaced in the extending direction A of the support arm 7. In such a case, in order to make the opening 16 face the wall hole 4a, insert a hand or a jig through the wall hole 4a and slide the wiring box 2A along the support arm 7A for position adjustment. Then, by operating through the opening 16 via the wall hole 4a, screw the mounting member 30 temporarily screwed to the mounting hole 31 into the insertion part 8 of the support arm 7A to firmly fix the wiring box 2A to the support arm 7A (see Fig. 6).

[0038] On the other hand, when supporting the wiring box 2A on the wide support arm 7B, after removing the access restriction portion 26 and expanding the space 24, the wiring box 2A is relatively slid (moved up and down) with the width direction of the support arm 7B as the insertion direction F into the space 24, so that the attachment portion 12A is hooked and supported on the support arm 7B. Then, the wiring box 2A is temporarily held with the connecting portion 27 abutting against the edge on the insertion tip side of the support arm 7B (see Fig. 7). Thereafter, the wiring box 2A is fixedly attached to the support arm 7B in substantially the same manner as the action of the wiring box 2A temporarily held on the narrow support arm 7A. Note that the removal of the access restriction portion 26 may be performed with the attachment portion 12A hooked on the support arm 7B.

[0039] Here, as shown in Fig. 6, by bringing the narrow support arm 7A into contact with the access restriction portion 26, the relative position of the main body 11 or the entire wiring box 2A with respect to the center in the width direction of the narrow support arm 7A, and as shown in Fig. 7, after removing the access restriction portion 26 with which the narrow support arm 7A is in contact and inserting the wide support arm 7B into the expanded space 24 expanded deeper than the removed access restriction portion 26 until further access is restricted, the relative position of the main body 11 or the entire wiring box 2A with respect to the center in the width direction of the wide support arm 7B coincides. Also, as shown in Fig. 6, by bringing the narrow support arm 7A into contact with the access restriction portion 26, the positions of the mounting hole 31 and the insertion portion 8 provided in the narrow support arm 7A are aligned. Further, as shown in Fig. 7, when the access restriction portion 26 with which the narrow support arm 7A is in contact is removed and the wide support arm 7B is inserted into the expanded space 24 expanded deeper than the removed access restriction portion 26 until further access is restricted, the positions of the mounting hole 31 and the insertion portion 8 provided in the wide support arm 7B are aligned.

[0040] As described above, according to the wiring box 2A of the present embodiment, a main body 11 having a running portion 10 along which the support arms 7A and 7B are arranged, an engaging portion 23 provided with a space 24 between the running portion 10 and the support arms 7A and 7B are inserted, a connecting portion 27 connecting the engaging portion 23 and the main body 11, and a mounting portion 12A attachable to the support arms 7A and 7B having a communication portion 25 communicating the space 24 with the outside and allowing the support arms 7A and 7B to be relatively slidably moved in a posture along the outer surface along which the support arms 7A and 7B are arranged toward the space 24. In the space 24, an entry restricting 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 edges of the inserted support arms 7A and 7B to restrict further entry. The entry restricting portion 26 is movable 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. Thereby, an appropriate insertion length corresponding to the width of the support arms 7A and 7B in the insertion direction F can be ensured.

[0041] Further, in the present embodiment, the entry restricting portion 26 is joined by a joining portion 28 that breaks by pressing 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 the position E that allows entry by breaking, so that the entry allowable state can be easily achieved.

[0042] Further, in the present embodiment, since the insertion direction F of the support arms 7A and 7B into the space 24 and the expansion direction of the space 24 are the same, it is possible to intuitively determine which part of the support arms 7A and 7B to abut against in order to widen the back side in the insertion direction F.

[0043] In addition, in the present embodiment, the main body 11 is formed with a mounting hole 31 through which a mounting member 30 that is inserted into the insertion portions 8 provided on the support arms 7A and 7B and determines the mounting position of the wiring box 2A in the extending direction A of the support arms 7A and 7B penetrates. Since the mounting member 30 screwed into the insertion portion 8 is screwed to the mounting hole 31, there is no need to separately prepare the mounting member 30. Also, alignment between the mounting hole 31 and the mounting member 30 is not required. In particular, in the present embodiment, the mounting member 30 is temporarily screwed into the mounting hole 31 at a position where it does not obstruct the insertion of the support arms 7A and 7B into the space 24, so that the mounting member 30 can be immediately screwed in.

[0044] Further, according to the body support device 1 of the present embodiment, the support body 3 is composed of two types: a support body 3A having a relatively narrow support arm 7A and a support body 3B having a relatively wide support arm 7B, with the widths of the support arms 7 extending from the fixing portion 6 by a certain width being different. By bringing the relatively narrow support arm 7A into contact with the entry restriction portion 26, the relative position of the entire main body 11 or wiring box 2A with respect to the center in the width direction of the relatively narrow support arm 7A is adjusted. Then, the entry restriction portion 26 with which the relatively narrow support arm 7A is in contact 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 contacts another entry restriction portion 26 or the connecting portion 27). At this time, the relative position of the entire main body 11 or wiring box 2A with respect to the center of the relatively wide support arm 7B is the same. As a result, even with the difference in the widths of the support arms 7A and 7B, the relative positions of the main body 11 or the wiring box 2A with respect to the centers of the support arms 7A and 7B can be made to coincide, enabling stable support. On the other hand, if the relatively wide support arm 7B is inserted into the narrow-width space 24 where the entry restriction portion 26 has not been removed, it will not be inserted properly and will become unstable.

[0045] Further, according to the arrangement body support device 1 of the present embodiment, the wiring box 2A has mounting holes 31 through which the mounting members 30 penetrate in the main body 11 or the engaging portion 23. The support 3 has different widths of the support arms 7 extending from the fixing portion 6 with a certain width, and consists of two types: a support 3A having a relatively narrow support arm 7A and a support 3A having a relatively wide support arm 7B. By relatively sliding the wiring box 2A with the width direction of the support arms 7A and 7B as the insertion direction F into the space 24, the wiring box 2A can be attached to the support arms 7A and 7B. By bringing the relatively narrow support arm 7A into contact with the entry restriction portion 26, the positions of the mounting hole 31 and the insertion portion 8 provided in the relatively narrow support arm 7A are aligned. The entry restriction portion 26 with which the relatively narrow support arm 7A is in contact is removed, and when the relatively wide support arm 7B is inserted into the expansion space 24 expanded deeper than the removed entry restriction portion 26 until further entry is restricted (until it contacts another entry restriction portion 26 or the connecting portion 27), the positions of the mounting hole 31 and the insertion portion 8 provided in the relatively wide support arm 7B are aligned. Thereby, even with the difference in width between the support arms 7A and 7B, the mounting positions of the mounting members 30 can be made to coincide with respect to the insertion portions 8 of the support arms 7A and 7B. On the other hand, if the relatively wide support arm 7B is inserted into the narrow-width space 24 where the entry restriction portion 26 has not been removed, the mounting position of the mounting member 30 will not coincide with the insertion portion 8 of the support arm 7B without being fully inserted.

[0046] In the first embodiment, a form including one entry restriction portion 26 in the insertion direction F of the support arms 7A and 7B into the space 24 is illustrated, but it is not limited thereto. For example, as shown in FIG. 15, a form including a plurality of stages (two stages in the figure) of entry restriction portions 26 in the insertion direction F of the support arms 7A, 7B, and 7C into the space 26 may be adopted. According to this form, the appropriate insertion lengths of the support arms 7A, 7B, and 7C can be changed in multiple stages.

[0047] <Second Embodiment> Next, the arrangement body support device of the second embodiment will be described. The substantially same constituent parts as those of the arrangement body support device of the first embodiment are denoted by the same reference numerals and detailed description thereof is omitted.

[0048] As shown in FIG. 10, the wiring box support device 1 includes a wiring box 2B disposed inside the wall and a support 3 for supporting the wiring box 2B.

[0049] The support 3 includes two types: a support 3A having a relatively narrow support arm 7A and a support 3B having a relatively wide support arm 7B, with the widths of the support arms 7 extending from the fixed part 6 with a constant width being different.

[0050] The wiring box 2A includes a main body 11 having a portion 10 along which the support arms 7A and 7B are arranged, and a mounting portion 12B capable of mounting the wiring box 2A to the support arms 7A and 7B. The main body 11 includes a peripheral wall composed of a bottom wall 14 and side walls 15 standing upright from the bottom wall 14, and an opening 16 facing the bottom wall 14 formed by surrounding it on the front end side of the side wall 14. The portion 10 along which is provided on the bottom wall 14.

[0051] The mounting portion 12B includes an engaging portion 23 provided with a space 24 into which the support arms 7A and 7B can enter between it and the portion 10 along which, a connecting portion 27 connecting both ends of the engaging portion 23 and the main body 11, and a communicating portion 25 communicating the space 24 with the outside to enable insertion by relatively sliding the support arms 7A and 7B in a posture along the outer surface along which the support arms 7A and 7B are arranged facing the space 24. This space 24 is formed between the bottom wall 14 of the main body 11 and the engaging portion 23. Further, the connecting portions 27 are provided facing each other with the space 24 therebetween.

[0052] In the space 24 of the attachment portion 12B, an entry restricting portion 26 is provided at the rear in the insertion direction F (extension direction A of the support arms 7A and 7B) of the support arms 7A and 7B into the space 24, which abuts against the edges of the inserted support arms 7A and 7B to restrict further entry. This entry restricting portion 26 is movable (specifically removable) to a retracted position E that allows the support arms 7A and 7B to enter further rearward 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. Further, in the wiring box 2B (specifically, the bottom wall 14 of the main body 11), a mounting hole 31 is formed through which a mounting member 30 inserted through the insertion portion 8 of the support arms 7A and 7B passes.

[0053] Next, the operation of the wiring box 2B and the arrangement body support device 1 having the above configuration will be described. When supporting the wiring box 2B on the narrow support arm 7A, the wiring box 2B is relatively slid from the tip side of the support arm 7A of the support body 3A in the cantilever state with the extension direction A of the support arm 7A as the insertion direction F into the space 24, so as to hook and support the attachment portion 12B with respect to the support arm 7A. At this time, the wiring box 2B is temporarily held with the entry restricting portion 26 abutting against the edge in the width direction of the support arm 7A. Next, after erecting the wall 4 on the front surface of the structure 5 and drilling a wall hole 4a at a predetermined position of the wall 4, 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, by operating through the wall hole 4a from the opening 16, the mounting member 30 temporarily screwed to the mounting hole 31 is screwed into the insertion portion 8 of the support arm 7A to fixedly mount the wiring box 2B with respect to the support arm 7A.

[0054] On the other hand, when supporting the wiring box 2B on the wide support arm 7B, after removing the access restriction portion 26 to expand the space 24, from the tip side of the support 3B in the cantilever state, the wiring box 2B is relatively slid with the extending direction A of the support arm 7B as the insertion direction F into the space 24, so that the attachment portion 12B is hooked and supported on the support arm 7B. At this time, the wiring box 2B is temporarily held with the connecting portion 27 abutting against the edge in the width direction of the support arm 7B. Then, in substantially the same manner as the operation of the wiring box 2B temporarily held on the narrow support arm 7A, the wiring box 2B is fixedly attached to the support arm 7B.

[0055] Here, by bringing the narrow support arm 7A into contact with the access restriction portion 26, the relative position of the main body 11 or the entire wiring box 2B with respect to the center in the width direction of the narrow support arm 7A, and the access restriction portion 26 with which the narrow support arm 7A is in contact are removed, and when the wide support arm 7B is inserted into the expanded space 24 expanded deeper than the removed access restriction portion 26, the relative position of the main body 11 or the entire wiring box 2B with respect to the center in the width direction of the wide support arm 7B coincides. Also, by bringing the narrow support arm 7A into contact with the access restriction portion 26, the positions of the mounting hole 31 and the insertion portion 8 provided in the narrow support arm 7A are aligned. Further, when the access restriction portion 26 with which the narrow support arm 7A is in contact is removed and the wide support arm 7B is inserted into the expanded space 24 expanded deeper than the removed access restriction portion 26, the positions of the mounting hole 31 and the insertion portion 8 provided in the wide support arm 7B are aligned.

[0056] From the above, according to the wiring box 2B and the disposed body support device 1 of the present embodiment, in the form where the insertion direction F of the support arms 7A and 7B into the space 24 is the extending direction A of the support arms 7A and 7B, the same operational effects as those of the disposed box 2A and the disposed body support device 1 of the first embodiment are achieved.

[0057] <Third Embodiment> Next, the disposed body support device of the third embodiment will be described, but the same constituent parts as those of the disposed body support device of the first embodiment are denoted by the same reference numerals and detailed description thereof is omitted.

[0058] As shown in FIGS. 11 and 12, the fixture support device 1 according to this embodiment includes a wiring box 2C disposed inside a wall and a support 3 for supporting the wiring box 2C.

[0059] The support 3 includes two types: a support 3A having a relatively narrow support arm 7A and a support 3B having a relatively wide support arm 7B, with the widths of the support arms 7 extending from the fixed portion 6 at a constant width being different. When the front side is defined as the side facing the wall surface side of the wiring box 2C, the support 3A and 3B are fixed to the structure such that the front-rear direction C thereof becomes the insertion direction F of the support arms 7A and 7B into the space 24.

[0060] The wiring box 2C includes a main body 11 having a running portion 10 along which the support arms 7A and 7B are arranged, and an attachment portion 12C that can attach the wiring box 2C to the support arms 7A and 7B. The main body 11 includes a peripheral wall composed of a bottom wall 14 and side walls 15 standing upright from the bottom wall 14, and an opening 16 facing the bottom wall formed by surrounding at the tip side of the side wall 14. The running portion 10 is provided on the side wall 15.

[0061] The attachment portion 12C has an engaging portion 23 provided with a space 24 for the support arms 7A and 7B to enter between it and the running portion 10, a connecting portion 27 connecting the engaging portion 23 and the main body 11, and a communicating portion 25 that allows the support arms 7A and 7B to be inserted by relatively sliding them in a posture along the outer surface along which the support arms 7A and 7B are arranged with the space 24 communicating with the outside. It has a substantially L-shaped plate form. This space 24 is formed between the side wall 15 of the main body 11 and the engaging portion 23. Further, the connecting portion 27 is provided facing the communicating portion 25.

[0062] In the space 24 of the attachment part 12C, an entry restricting part 26 is provided at the back in the insertion direction F (front-rear direction C) of the support arms 7A and 7B into the space 24, which abuts against the inserted support arms 7A and 7B to restrict further entry. Also, in the attachment part 12C, the connecting part 27 and the communication part 25 are in opposed positions, and their arrangement direction coincides with the opposed direction of the bottom wall 14 and the opening 16. Further, in the wiring box 2C (specifically, the side wall 15 of the main body 11), a mounting hole 31 is formed through which a mounting member 30 inserted through the insertion part 8 of the support arms 7A and 7B passes.

[0063] Next, the operation of the wiring box 2C and the device support apparatus 1 having the above configuration will be described. When supporting the wiring box 2C on the narrow support arm 7A, the wiring box 2C is relatively slid in the front-rear direction C as the insertion direction F into the space 24, so that the attachment part 12C is hooked on and supported by the support arm 7A (see Fig. 12(a)). Then, the wiring box 2C is temporarily held at the first position P1 with the entry restricting part 26 abutting against the edge on the insertion tip side of the support arm 7A. This first position P1 is a position shifted from the front surface part 5a by the thickness of the body edge member 33 to which the opening 16 of the wiring box 2C is fixed to the front surface part 5a facing the wall surface side of the structure 5. Next, after erecting the wall 4 on the front surface of the structure 5 and drilling a wall hole 4a at a predetermined position of the wall 4, if necessary, the wiring box 2C is slid along the support arm 7A to adjust the position so that the opening 16 faces the wall hole 4a. Then, by an operation through the opening 16 via the wall hole 4a, the mounting member 30 temporarily screwed to the mounting hole 31 is screwed into the insertion part 8 of the support arm 7A to fixedly mount the wiring box 2C to the support arm 7A.

[0064] Also, when supporting the wiring box 2C on the narrow support arm 7A, after removing the access control part 26 and expanding the space 24, the wiring box 2C is relatively slid in the front-rear direction C as the insertion direction F into the space 24, so as to hook and support the attachment part 12C with respect to the support arm 7A (see Fig. 12(b)). Then, the wiring box 2C is temporarily held at the second position P2 with the connecting part 27 abutting against the edge on 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 surface part 5a facing the wall surface side of the structure 5 or a position away from the back surface of the wall, and is a position shifted from the first position P1 by the thickness of the body edge member 33. Thereafter, the wiring box 2C is fixedly secured to the support arm 7A in substantially the same manner as the operation of the wiring box 2C temporarily held at the above-described first position P1.

[0065] On the other hand, when supporting the wiring box 2C on the wide support arm 7B, after removing the access control part 26 and expanding the space 24, the wiring box 2C is relatively slid in the front-rear direction C as the insertion direction F into the space 24, so as to hook and support the attachment part 12C with respect to the support arm 7B (see Fig. 12(c)). Then, the wiring box 2C is temporarily held at the first position P1 with the connecting part 27 abutting against the edge on the insertion tip side of the support arm 7. Thereafter, the wiring box 2A is fixedly secured to the support arm 7B in substantially the same manner as the operation of the wiring box 2C temporarily held on the narrow support arm 7A of the above.

[0066] Here, as shown in FIGS. 12(a) and 12(c), by bringing the narrow support arm 7A into contact with the access restricting portion 26, the relative position of the main body 11 or the entire wiring box 2C with respect to the center in the width direction of the narrow support arm 7A, and the access restricting portion 26 with which the narrow support arm 7A is in contact are removed. When the wide support arm 7B is inserted into the expanded space 24 expanded deeper than the removed access restricting portion 26 until further access is restricted, the relative position of the main body 11 or the entire wiring box 2C with respect to the center in the width direction of the wide support arm 7B coincides. Also, by bringing the narrow support arm 7A into contact with the access restricting portion 26, the positions of the mounting hole 31 and the insertion portion 8 provided in the narrow support arm 7A are aligned. Further, when the access restricting portion 26 with which the narrow support arm 7A is in contact is removed and the wide support arm 7B is inserted into the expanded space 24 expanded deeper than the removed access restricting portion 26 until further access is restricted, the positions of the mounting hole 31 and the insertion portion 8 provided in the wide support arm 7B are aligned.

[0067] From the above, according to the wiring box 2C and the disposed body support device 1 of the present embodiment, the same operational effects as those of the disposed box 2A and the disposed body support device 1 of the first embodiment are achieved. The along portion 10 is the side wall 14, and the attachment portion 12C is such that the connecting portion 27 and the communicating portion 25 are in opposed positions, and their arrangement direction coincides with the opposed direction of the bottom wall 14 and the opening 16. Therefore, the position of the opening 16 can be changed in the front-rear direction C (the direction of approaching and separating from the wall surface) with respect to the support arms 7A and 7B installed on the back of the wall. That is, it can be selectively used depending on whether there is a body edge member 33 or not.

[0068] Also, according to the mounting body support device 1 of the present embodiment, when the front-rear direction C of the supports 3A and 3B is defined as the front side facing the wall surface side of the wiring box 2C, the supports 3A and 3B can be fixed to the structure 5 such that the front-rear direction C becomes the insertion direction F of the support arms 7A and 7B into the space 24. The position of the opening 16 with respect to the end of the support arms 7A and 7B facing the wall surface side can be changed to a first position P1 determined by the support arms 7A and 7B coming into contact with the entry restricting portion 26, and a second position P2 that is relatively different from the first position P1 in the front-rear direction C when the support arms 7A and 7B enter the extended end where the entry restricting portion 26 is removed. Thereby, the attachment position of the wiring box 2C in the front-rear direction C (the direction of approaching and separating from the wall back) with respect to the fixed support arms 7A and 7B can be easily changed.

[0069] Furthermore, in the present embodiment, the supports 3A and 3B are fixed to the side surfaces of the column 5 as a structure on the wall back side. The first position P1 is a position shifted from the front surface portion 5a by the thickness of the body edge member 33 to which the opening 16 is fixed to the front surface portion 5a facing the wall surface side of the column 5. The second position P2 is a position where the opening 16 is flush with the front surface portion 5a facing the wall surface side of the column 5 or a position away from the wall back surface, and is a position shifted from the first position P1 by the thickness of the body edge member 33. Therefore, the opening 16 can be arranged at an appropriate position corresponding to the body edge member 33.

[0070] In the third embodiment, the form of hooking the attachment portion 12C from the wall surface side to the support arms 7A and 7B is illustrated, but the present invention is not limited thereto. For example, as shown in FIG. 13, the attachment portion 12C may be hooked to the support arms 7A and 7B from the wall back side. In this form, the first position P1 when the support arm 7A comes into contact with the entry restricting portion 26 is a position where the opening 16 of the wiring box 2C is flush with the front surface portion 5a facing the wall surface side of the structure 5 or a position away from the wall back surface, and is a position shifted from the first position P1 by the thickness of the body edge member 33. Furthermore, the second position P2 when the support arm 7A comes into contact with the connecting portion 27 is a position where the opening 16 of the wiring box 2C is shifted from the front surface portion 5a by the thickness of the body edge member 33. That is, the position of the opening 16 can be changed in the front-rear direction C with respect to the support arms 7A and 7B installed on the wall back side, and can be selectively used depending on whether there is a body edge member 33.

[0071] In the present invention, the embodiments are not limited to the above, and various modified embodiments can be provided within the scope of the present invention according to the purpose and application. That is, in the above first to third embodiments, the support 3 having the support arm 7 extending in the horizontal direction A is exemplified. However, the present invention is not limited to this. For example, as shown in FIG. 14, a support 3 having a support arm 7 standing vertically from below may be adopted. As this form, for example, an attachment portion 12 is provided on the bottom wall 14 of the main body 11, and a form in which the wiring box 2 can be positionally adjusted in the horizontal direction B in addition to the vertical direction A (see FIG. 14(a)), or an attachment portion 12 is provided on the side wall 15 of the main body 11, and a form in which the wiring box 2 can be positionally adjusted in the direction C of approaching and separating from the wall in addition to the vertical direction A (see FIG. 14(b)) can be adopted.

[0072] Further, in the present embodiment, an example is shown in which the mounting holes 31 of the mounting body to which the mounting members (screws) 30 are attached are shared for the support arms 7 having different widths. However, the mounting holes 31 may be provided at different positions according to the support arms 7 of each width and may not be shared.

[0073] Furthermore, in the above first to third embodiments, the support 3 having the plate-shaped support arm 7 is exemplified. However, the present invention is not limited to this. For example, a support 3 having a screw-shaped or rod-shaped support arm 7 may be adopted.

[0074] In addition, in the above first to third embodiments, a fixing form in which the mounting body (wiring boxes 2A to 2C) and the support arm 7 are mutually coupled by the mounting member 30 is exemplified. However, the present invention is not limited to this. For example, a state where the support arm 7 is simply hooked may be regarded as the main fixing, and the fixing in which the mounting body and the support arm 7 are mutually coupled by the mounting member 30 may be omitted. Furthermore, for example, when the mounting body is the wiring boxes 2A to 2C, without inserting (threading) the mounting member 30 into the support arm 7, in a state where the openings 16 of the wiring boxes 2A to 2C and the wall holes 4a are aligned, the wiring fixtures fixed to the appliance mounting portion by screws may be used to sandwich the wall 4 between the wiring fixtures and the wiring boxes 2A to 2C to serve as the main fixing.

A disposed body support device comprising: The support body is composed of two types of support bodies, one having a support arm with a relatively narrow width and the other having a support arm with a relatively wide width, where the width of the support arm extending from the fixing portion is different, or has a support arm in which the width of the support arm is different halfway in the extending direction from the fixing portion, and includes a portion where a relatively narrow support arm is formed and a portion where a relatively wide support arm is formed, By bringing the narrow-width support arm into contact with the entry restricting portion, the relative position of the main body or the entire disposed body with respect to the center in the width direction of the narrow-width support arm, removing the entry restricting portion with which the narrow-width support arm has come into contact, and inserting the wide-width support arm into an expansion space expanded deeper than the removed entry restricting portion until further entry is restricted, and the relative position of the main body or the entire disposed body with respect to the center of the wide-width support arm coincides. A disposed body support device characterized by this.

9. A disposed body according to any one of claims 1 to 7, A support body including a fixing portion fixed to a structure inside a wall, and a support arm extending from the fixing portion so as to be spaced apart from the structure, and an insertion portion through which an attachment member for determining an attachment position of the disposed body in the extending direction of the support arm is inserted is provided in the support arm. A disposed body support device comprising: The disposed body has an attachment hole through which the attachment member passes. The support body is composed of two types of support bodies, one having a support arm with a relatively narrow width and the other having a support arm with a relatively wide width, where the width of the support arm extending from the fixing portion is different, or has a support arm in which the width of the support arm is different halfway in the extending direction from the fixing portion, and includes a portion where a relatively narrow support arm is formed and a portion where a relatively wide support arm is formed, The disposed body can be attached to the support arm by relatively sliding the disposed body with the width direction of the support arm as the insertion direction into the space. By bringing the narrow-width support arm into contact with the entry restricting portion, the positions of the attachment hole and the insertion portion provided in the narrow-width support arm are aligned. When removing the entry restricting portion against which the narrow support arm of the width abuts, and inserting the wide support arm of the width into the expanded space expanded deeper than the removed entry restricting portion until further entry is restricted, the mounting hole and the insertion portion provided in the wide support arm of the width are aligned. A body support device characterized by this.

10. The disposed body according to claim 7, A support body including a fixing portion fixed to a structure inside the wall, and a support arm extending from the fixing portion so as to be separated from the structure, A body support device comprising: When the front-rear direction is defined with the side facing the wall surface side of the disposed body as the front, the support body can be fixed to the structure such that the front-rear direction becomes the insertion direction of the support arm into the space, The position of the opening with respect to the end of the support arm facing the wall surface side, A first position determined by the support arm abutting against the entry restricting portion, The support arm enters the tip where the entry restricting portion is removed and expanded, and the first position can be changed to a second position that is relatively different from the first position in the front-rear direction. A body support device characterized by this.
