Description

[Technical field]

[0001] The present invention relates to a distribution board arrangement structure and the like. [Background technology]

[0002] In buildings with many rooms, such as hotels, electricity is often supplied to each room via a distribution board installed in an EPS (Electric Pipe Space), etc. The EPS is an equipment space for installing electrical wiring and piping, but it is kept as small as possible in order to secure large spaces for the rooms and common areas of the building.

[0003] Patent Document 1 describes a method in which the back of a distribution board installed in a compartment provided in a common area of ​​a building is finished to be flush with the wall surrounding the compartment, and when work is to be performed on the distribution board, the distribution board is rotated around an axis of rotation and deployed outside the compartment, thereby making the compartment smaller and expanding the common area. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Publication No. 5-137218 Summary of the Invention [Problem to be solved by the invention]

[0005] As described above, the space of the EPS is limited, so the workability of maintenance and other operations within the EPS is by no means good. In order to improve the workability within the EPS, it is effective to make the position of the distribution board variable as in Patent Document 1, but in Patent Document 1, the distribution board installed in the compartment is rotated to switch its position to the position at the time of work relative to the distribution board, and since the position of the rotation axis of the distribution board is fixed, there is a limit to changing the position of the distribution board.

[0006] The present invention has been made in consideration of the above problems, and aims to provide a distribution board arrangement structure that allows the position of the distribution board to be changed and facilitates work within the equipment space of an EPS, etc. [Means for solving the problem]

[0007] In order to solve the above-mentioned problems, the present invention provides an arrangement structure for arranging a distribution board within the equipment space of a building, characterized in that a support member to which the distribution board is attached moves along a rail, thereby making it possible to switch the position of the support member between a work position for performing work on the distribution board and a storage position retracted from the work position.

[0008] In the present invention, the support member to which the distribution board is attached is moved along a rail, and the position of the support member can be switched between a working position for performing work on the distribution board and a storage position retracted from the working position. In this way, by making the position of the support member (distribution board) variable, the space within the equipment space can be effectively utilized, maintenance work and other work can be easily performed within the equipment space, and the proportion of the equipment space in the building can be reduced. In addition, since the support member moves along the rail, the position of the support member can be changed relatively widely, which contributes to effective use of space.

[0009] The rail is provided, for example, horizontally above or below the support member, and the support member is attached to a slide member along which the support member moves. This allows the support member to which the distribution board is attached to be moved horizontally.

[0010] The slide members may be arranged in a pair with a gap therebetween in the extension direction of the rail, the support member may be attached to both slide members, the slide members may be rotatable within a plane, and the rail may be arranged bent in the plane. This allows the support member to which the distribution board is attached to be moved along the rail and its orientation to be changed.

[0011] The rails may be provided vertically on either side of the support member, the support member moving along each rail. This allows the support member to which the distribution board is attached to be moved vertically.

[0012] It is preferable to have a fixing mechanism for fixing the support member at the working position or the storage position. This allows the distribution board to be securely fixed in the working position or the storage position.

[0013] The fixing mechanism desirably includes a pin and a hole into which the pin is inserted. This allows the support member to be fixed with a simple mechanism. Effect of the Invention

[0014] The present invention can provide a distribution board layout structure that makes it possible to change the position of the distribution board and facilitates work within the equipment space of an EPS or the like. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0016] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

[0017] [First embodiment] Fig. 1 is a diagram showing an arrangement structure 1 according to a first embodiment of the present invention. This arrangement structure 1 is for arranging a distribution board 2 attached to a support member 3 in an equipment space 9 of a building such as an EPS, Fig. 1(a) is a plan view of the equipment space 9, and Fig. 1(b) is a view of the support member 3 as seen from the direction indicated by the arrow a in Fig. 1(a).

[0018] As shown in FIG. 1, the arrangement structure 1 includes a distribution board 2, a support member 3, a rail 4, a slide member 5, and the like.

[0019] The distribution board 2 is a device that branches the electricity transmitted from the distribution board and supplies it to electrical equipment such as indoor outlets and lighting. A cable that transmits electricity from the distribution board and a cable that supplies electricity to the electrical equipment are connected to the distribution board 2. Note that the cables are not shown in Figure 1 and the other figures described below.

[0020] The support member 3 is a plate-like member, and is disposed with its plate surface in the vertical direction. The distribution board 2 is attached to the plate surface of the support member 3. There is no particular limit to the material of the support member 3, as long as it has the strength and rigidity to mount the distribution board 2 and maintain the plate surface in the vertical direction. For example, iron, fiber-reinforced plastic, aluminum, synthetic wood, etc. can be used. The shape of the support member 3 is also not limited to a plate shape, and it is only necessary that the distribution board 2 can be mounted on it.

[0021] The rail 4 is provided horizontally above the support member 3. The support member 3 moves horizontally along the rail 4. The rail 4 has a C-shaped cross section with a slit-like opening on the lower surface.

[0022] The slide member 5 is a member that slides along the rail 4, and in this embodiment, a hoist wheel is used. The slide member 5 has a bearing-like running part 51 that is arranged inside the rail 4, and a shaft part 52 that extends downward from the running part 51 through an opening in the rail 4, and is rotatable within a plane. A pair of slide members 5 are arranged with a gap in between in the extension direction of the rail 4. The support member 3 is attached to the lower ends of the shaft parts 52 of both slide members 5 and supported in a suspended manner, and is arranged floating above the floor part 92 of the equipment space 9.

[0023] The support member 3 with the distribution board 2 attached thereto can be moved along the rails 4 to a position corresponding to the door 91 of the equipment space 9 as shown in Fig. 2. An operator can open the door 91 of the equipment space 9, move the support member 3 from the position shown in Fig. 1(a) to the working position shown in Fig. 2, and perform work on the distribution board 2 from outside the equipment space 9. After completing the work, the support member 3 can be retracted to the storage position shown in Fig. 1(a) and stored.

[0024] In this embodiment, by storing the support member 3 to which the distribution board 2 is attached in the storage position, a space for performing maintenance on other equipment in the equipment space 9 is secured. For example, in the example of Fig. 1(a), by storing the support member 3 in the storage position, a sufficient working space S for the piping P arranged in the equipment space 9 can be secured.

[0025] The arrangement structure 1 may be installed when constructing a new equipment space 9, or may be installed in an existing equipment space 9 as a post-construction work. The arrangement structure 1 may be attached to a gate-shaped frame (not shown) in advance in a factory or the like to form a unit, in which case the frame is brought to the site and installed in the equipment space 9, and the cables are wired, simplifying the work on site. The rails 4 can be supported by being suspended from beams, ceilings, walls, etc. in the equipment space 9, but the beam parts of the frame can also be used as the rails 4, or the rails 4 can be attached to the beam parts of the frame in advance.

[0026] As described above, in the arrangement structure 1 of this embodiment, the support member 3 to which the distribution board 2 is attached is moved horizontally along the rails 4, and the position of the support member 3 can be switched between a work position for performing work on the distribution board 2 and a storage position retracted from the work position. In this way, by making the position of the support member 3 (distribution board 2) variable, the space within the equipment space 9 can be effectively utilized, work such as maintenance within the equipment space 9 can be easily performed, and the proportion of the building that the equipment space 9 occupies can be reduced. In addition, since the support member 3 moves along the rails 4, a relatively large position change of the support member 3 is possible, which contributes to effective use of space.

[0027] However, the present invention is not limited to the above embodiment. For example, in this embodiment, the rails 4 prevent the support member 3 from moving in an unintended direction, and damage to the piping P and the like due to contact with the support member 3 can be prevented, but a fixing mechanism for fixing the support member 3 at the working position or the storage position can be further provided to reliably fix the position of the support member 3 and limit the movement of the support member 3 during an earthquake, thereby preventing damage to the piping P and the like due to contact with the support member 3.

[0028] 3(a) shows an example of the fixing mechanism 6. In this example, the fixing mechanism 6 has a pin 61 provided on the support member 3 and a hole 62 provided in the floor 92 of the equipment space 9. The pin 61 has a protrusion 611 protruding laterally, and by placing this protrusion 611 on one of a pair of left and right protrusion pieces 631 of a holding fitting 63 fixed to the support member 3, the lower end of the pin 61 can be held in a state where it is raised above the floor 92.

[0029] When fixing the position of the support member 3, the pin 61 is rotated to move the protrusion 611 between the pair of protruding pieces 631, and then the pin 61 is lowered as shown in Fig. 3(b) to insert the lower end into the hole 62 in the floor part 92. At this time, the protrusion 611 of the pin 61 is placed on the placement part 632 provided below the protruding pieces 631.

[0030] The arrangement of the rails 4 is not particularly limited, and can be determined according to the planar shape of the equipment space 9 and the positions of the pipes P, etc. For example, as shown in the arrangement structure 1a of Fig. 4(a), the rails 4 may be arranged so as to be bent in a plane. The support member 3 to which the distribution board 2 is attached can be moved from the storage position shown in Fig. 4(a) along the rails 4 as shown in Fig. 4(b) to a working position corresponding to the door 91 of the equipment space 9 as shown in Fig. 4(c), and its orientation can be changed during the movement.

[0031] A worker can open the door 91 of the equipment space 9, move the support member 3, which is in the storage position shown in Fig. 4(a), to the working position shown in Fig. 4(c), and perform work on the distribution board 2 from outside the equipment space 9. After completing the work, the support member 3 can be retreated to the storage position shown in Fig. 4(a) and stored.

[0032] Moreover, a worker who has entered the equipment space 9 can move the support member 3 from the position shown in Fig. 4(a) to the position shown in Fig. 4(c) in the same manner as described above, thereby securing a work space S for performing maintenance on the piping P and the like in the equipment space 9. After completing the maintenance, the worker can retreat the support member 3 to the storage position also shown in Fig. 4(a), store the support member 3, and then go outside.

[0033] In this embodiment, the rails 4 are provided above the support member 3, but as shown in the arrangement structure 1b in Fig. 5, the rails 4 may be arranged above and below the support member 3a. Fig. 5(a) is a plan view of the equipment space 9, and Fig. 5(b) is a view of the support member 3a as seen from the direction indicated by the arrow b in Fig. 5(a).

[0034] In this case, a pair of slide members 5 similar to those described above are also attached to the bottom of the support member 3a with a gap in between in the extension direction of the rails 4. In the example of Fig. 5, the support member 3a is a shelf-like member that houses the distribution board 2 therein, and the rails 4 are provided in two rows above and below the support member 3a.

[0035] A plurality of support members 3a are arranged in the equipment space 9, and each support member 3a (distribution board 2) can move in parallel along the rails 4. The support member 3a to which the distribution board 2 is attached can move from a storage position on the left side of the equipment space 9 shown in Fig. 5(a) to a working position on the right side of the equipment space 9 shown in Fig. 6 by moving along the rails 4.

[0036] FIG. 6 shows a state in which one of the multiple support members 3a has been moved to the working position, but the other support members 3a can be moved from the storage position to the working position in the same way. The worker can move the support member 3a from the storage position shown in FIG. 5(a) to the working position shown in FIG. 6 and perform work on the distribution board 2 from inside the equipment space 9 or outside the equipment space 9. After completing the work, the support member 3a can be retreated to the storage position shown in FIG. 5(a) and stored. Note that in this example, the rails 4 are provided above and below the support member 3a, but the rails 4 can also be provided only below it.

[0037] In this embodiment, the rails 4 are provided in a horizontal direction, but the direction of the rails 4 is not limited to this, and the rails 4 may be provided in a vertical direction, for example. An example in which the rails 4 are provided in a vertical direction will be described below as a second embodiment. In the second embodiment, differences from the first embodiment will be described, and similar configurations will be denoted by the same reference numerals in the drawings and the like, and description thereof will be omitted. Furthermore, the configuration described in the first embodiment can be used in combination with the configuration described in the second embodiment as necessary.

[0038] [Second embodiment] 7 is a diagram showing an arrangement structure 10 according to a second embodiment of the present invention. This arrangement structure 10 also arranges a distribution board 2 attached to a support member 3 in an equipment space 9 of a building such as an EPS, but differs from the arrangement structure 1 of the first embodiment mainly in that the rails 4 are arranged vertically on both sides of the support member 3.

[0039] Fig. 7(a) is a side view of the arrangement structure 10 arranged in the equipment space 9, and Fig. 7(b) is a front view of the arrangement structure 10. The front refers to the side of the arrangement structure 10 on which the distribution board 2 is provided.

[0040] 7, the arrangement structure 10 includes a distribution board 2, a support member 3, a rail 4, a fixing mechanism 7, etc. In this embodiment as well, the distribution board 2 is attached to the plate surface of the plate-shaped support member 3, and both sides of this support member 3 are inserted into grooves of the rail 4 and move up and down along the rail 4.

[0041] In this embodiment, the support member 3 is raised and lowered manually by an operator, but an automatic lifting device equipped with a motor, pulley, etc. may also be used. Also, the above-mentioned slide members 5 may be attached to both sides of the support member 3, and the running parts 51 may run along the rails 4. Other slide members that move along the rails 4 may also be used.

[0042] The support member 3 with the distribution board 2 attached can be moved along the rails 4 to be lowered from the storage position shown in FIG. 7(b) to a lower working position. A worker can lower the support member 3 from the storage position shown in FIG. 7(b) to the working position shown in FIG. 8 and perform work on the distribution board 2. After completing the work, the support member 3 can be moved upward and retreated to the storage position shown in FIG. 7(b). By retreating the support member 3 to the storage position, a space is secured below the support member 3 for performing maintenance on other equipment within the equipment space 9.

[0043] The fixing mechanisms 7 are for fixing the height (position) of the support member 3, and are attached to each rail 4 at intervals in the height direction. Figure 9 shows the fixing mechanism 7, and is a cross section taken along line AA in Figure 7(b).

[0044] 9, the fixing mechanism 7 is, for example, a pin with a head, and has a head 71 and a shaft 72 fixed to the head 71. The shaft 72 of the pin is arranged to pass through holes 41 on both side surfaces of the rail 4 and through hole 31 in the support member 3 from one of the side surfaces of the rail 4 that sandwich the support member 3.

[0045] The tip of shaft portion 72 protrudes from the other side surface of rail 4. A protrusion 721 is provided at the tip, which protrudes from shaft portion 72 and engages with the other side surface of rail 4. The pin is attached to rail 4 by head portion 71 and protrusion 721, and the height of support member 3 is fixed by this pin.

[0046] The fixing mechanism 7 is provided at a height that hits the upper and lower ends of the support member 3 when the support member 3 is in the storage position shown in Fig. 7(b) and the upper and lower ends of the support member 3 when the support member 3 is in the working position shown in Fig. 8. In this embodiment, the lower end of the support member 3 when the support member 3 is in the storage position shown in Fig. 7(b) is at the same height as the upper end of the support member 3 when the support member 3 is in the working position shown in Fig. 8, and the fixing mechanism 7 is provided at three locations in the height direction of each rail 4.

[0047] When the button 711 of the head 71 is pressed, the projection 721 of the shaft 72 retracts into the shaft 72, making it possible to remove the pin. When moving the support member 3 from the working position or the storage position, the pin is removed as described above, and when fixing the support member 3 at the storage position or the working position thereafter, the button 711 of the head 71 is kept pressed while the shaft 72 is passed through the hole 41 of the rail 4 and the hole 31 of the support member 3, and then the button 711 is released to project the projection 721 at the tip of the shaft 72, thereby attaching the pin.

[0048] As described above, in the second embodiment of the arrangement structure 10, by moving the support member 3 to which the distribution board 2 is attached vertically along the rail 4, the position of the support member 3 can be switched between a working position for performing work on the distribution board 2 and a storage position retracted from the working position, thereby obtaining the same effect as in the first embodiment.

[0049] In addition, the fixing mechanism 7 consisting of the pins and holes 31, 41 described above allows the support member 3 to be easily and securely fixed in the working position or storage position, thereby limiting the movement of the support member 3 during an earthquake, etc., and preventing damage to other equipment in the equipment space 9 due to contact with the support member 3.

[0050] The configuration of the fixing mechanism 7 is not limited to the above. For example, the fixing mechanism 7a in Fig. 10(a) fixes the height (position) of the support member 3 by urging the shaft of a pin 73 passed through a hole 41 of the rail 4 toward the support member 3 by a spring 74, and inserting the tip of the pin into a bottomed hole 32 of the support member 3. This makes it easy to fix the position of the support member 3. When moving the support member 3, the pin 73 is pulled from the outside and the tip of the pin is pulled out of the hole 32.

[0051] Also, Figure 10(b) shows a vertical cross section of the side of the support member 3 located in the groove of the rail 4. The fixing mechanism 7b shown in Figure 10(b) is configured such that a bolt 75 (pin) is passed through hole 41 in the rail 4 and hole 31 in the support member 3, and a nut 76 is fastened to one end of the bolt 75 (pin).

[0052] The other end of bolt 75 protrudes outward from rail 4, and a locking piece 751 that rotates under its own weight is attached to this end. Bolt 75 is attached to rail 4 with this locking piece 751 and nut 76, and the height (position) of support member 3 is fixed by bolt 75. When supporting member 3 is to be moved, after detaching nut 76 from bolt 75, bolt 75 can be pulled out from the locking piece 751 side.

[0053] In this case, the support member 3 can be fixed more securely by tightening the nut 76. However, a tool is required to tighten the nut 76, and fixing the support member 3 takes some effort. Note that in order to prevent the support member 3 from moving in the fore-aft direction, a camber (wedge) can be provided between the support member 3 and the side surface of the rail 4 within the groove of the rail 4. The fore-aft direction refers to the direction perpendicular to the plate surface of the support member 3, and corresponds to the left-right direction in Figure 10(b).

[0054] The fixing mechanism 7c in FIG. 10(c) determines the width of the groove of the rail 4 and the thickness of the support member 3 so that the support member 3 can move in the forward and backward directions indicated by the arrow d, and then attaches a hook 77 to the back surface of the support member 3 (the surface opposite the distribution board 2) and hooks this hook 77 onto a bar 78 to fix the height (position) of the support member 3. When moving the support member 3, the support member 3 is lifted slightly and moved forward, and the hook 77 is removed from the bar 78. "Forward" refers to the direction of the distribution board 2 as seen from the support member 3. With this fixing mechanism 7c, the position of the support member 3 can be easily fixed and released by operating the support member 3 while holding it in the hand, eliminating the need to operate a separate member such as a pin.

[0055] Although the preferred embodiment of the present invention has been described above with reference to the accompanying drawings, the present invention is not limited to the above examples. It is clear that a person skilled in the art can come up with various modified or altered examples within the scope of the technical ideas disclosed in this application, and it is understood that these also naturally belong to the technical scope of the present invention.
