FIG. 7 is a cross-sectional view of the first frame member 2 of the board device 100 according to the first embodiment, taken along the line CC. FIG. 8 is a schematic cross-sectional view of the board device 100 according to the first embodiment, taken along the line AA. FIG. 9 is an enlarged cross-sectional view of the portion where the first recessed portion 4 and the second protruding portion 10 of the board device 100 according to the first embodiment are engaged.

[0011] The panel device 100 comprises a first housing 1 and a second housing 7. The panel device 100 is installed in the elevator machine room. As shown in FIG. 1 , the elevator machine room has a floor 29 and a ceiling 28, and the panel device 100 is installed on the upper surface of an under-panel duct 27 provided above the floor 29. The first housing 1 houses a control panel, which is a control device 34, inside. The second housing 7 houses a power receiving and distribution panel, which is a power receiving and distribution device 35, inside.

[0012] The ceiling 28 is the ceiling surface of the elevator machine room in which the panel device 100 is installed.

[0013] The floor 29 is the floor surface of the elevator machine room in which the panel device 100 is installed.

[0014] The under-panel duct 27 is installed on the floor 29. The inside of the under-panel duct 27 is hollow, and cables (not shown) coming out from the panel device 100 are provided inside the under-panel duct 27. The first housing 1 and the second housing 7 are fixed adjacent to each other on the upper surface of the under-panel duct 27 with bolts or the like (not shown) and arranged.

[0015] The first housing 1 has a first frame member 2 and a first side plate 3 .

[0016] The first frame member 2 is composed of a frame forming a rectangular parallelepiped shape. The first frame member 2 has openings on the side, top, and bottom surfaces of the rectangular parallelepiped shape. The frame forming the first frame member 2 is, for example, a metal plate formed by bending a rod-shaped rectangular flat plate into an L-shape in the short direction. The first frame member 2 has a notch 26 so that the first side panel 3 can be attached without interfering with the first frame member 2. Details of the notch 26 will be described later.

[0017] The first side plate 3 is attached to a side surface of the first frame member 2 and fixed with fixing screws 33. As shown in FIG. 2, the first side plate 3 is attached to one of the multiple side surfaces of the rectangular parallelepiped first frame member 2. Note that FIG. 2 is a schematic view, and components other than the illustrated first side plate 3 and first frame member 2 are not shown. Note that, although the fixing screws 33 for fixing the first side plate 3 to the first frame member 2 are provided in four locations in FIG. 5, this is not limited to this, and more than four locations may be provided. Furthermore, as shown in FIG. 4, the first side plate 3 is configured to be detachable from the first frame member 2.

[0018] The first side panel 3 has a first recess 4 protruding toward the inside of the first frame member 2 and a first flat portion 6. The first recess 4 is formed, for example, by pressing a mold against a flat plate and bending it. The first recess 4 is formed in the first side panel 3 so that the cross-sectional shape of the first recess 4 when cut along a plane parallel to the floor 29 is the same at any cross-sectional position in the vertical direction. The first flat portion 6 is a flat portion of the first side panel 3 other than the area where the first recess 4 is formed. Note that the first recess 4 shown in FIG. 4 is formed vertically from the lower end to the upper end of the flat plate, but this shape is not necessarily limited to this and it may be formed in any part of the flat plate. Furthermore, as shown in FIG. 9, the first inclination angle 30 is the angle between the plane of the first flat portion 6 and the edge of the portion of the first recess 4 protruding toward the inside. Details of the first inclination angle 30 will be described later.

[0019] As shown in FIGS. 5 and 6, the cutout portion 26 is formed in a horizontal portion of the frame of the first frame member 2 that forms a rectangular parallelepiped shape. FIG. 6 is an enlarged side view of the cutout portion in range B shown in FIG. 5, with the top side plate of the first housing 1 and the first side plate 3 omitted. The dotted lines in FIG. 6 are hidden lines that indicate a portion of the first frame member 2 that has been bent in the direction of the depth of the page (horizontal direction). FIG. 7 shows a cross-sectional view of the first frame member 2 at the CC cross section position shown in FIG. 6, viewed from the direction indicated by the arrow in the figure. The first side plate 3 is omitted in FIG. 7. As shown in FIGS. 6 and 7, the first frame member 2 is an L-shaped sheet metal.

[0020] Here, each side forming the rectangular frame of the first frame member 2 is formed from sheet metal obtained by bending a rod-shaped rectangular flat plate into an L shape in the short direction. Furthermore, as described above, of the sides forming the rectangular frame of the first frame member 2, the top and bottom sides of the side surface to which the first side panel 3 is attached have cutout portions 26.

[0021] Here, we will explain the general procedure for manufacturing the sides of the first frame member 2 having the cutout portion 26. First, the flat plate that forms the frame base of the first frame member 2 is a rod-shaped rectangular flat plate, and the plate material in the area corresponding to the cutout portion is partially cut into a square shape and subjected to removal processing. After removal processing, the flat plate is bent to give it a 90-degree angle. In this way, an L-shaped frame having the cutout portion 26 is manufactured.

[0022] 6 and 7 show lengths L1, L2, and L3, which are the dimensions around the cutout of the first frame member. When the frame forming the first frame member 2 is a rod-shaped rectangular flat plate, length L1 corresponds to the length of the portion removed by the aforementioned removal process along the short side of the rectangular flat plate. In FIG. 7, in the cross section of the L-shaped frame, length L2 from the base of the inner periphery of the right-angle bent portion to the edge of the removed portion is greater than the thickness L3 of the flat plate that forms the frame base of the first frame member 2. Having L2 greater than L3 facilitates the right-angle bending of the removed flat plate. When the first side panel 3 is attached to the first frame member 2, the upper and lower portions of the first recess 4 of the first side panel 3 are inserted into the cutout 26, as shown in FIGS. 2 and 5. By forming the notch 26 in the first frame member 2, the first recess 4 can be attached to the first frame member 2 without interfering with it.

[0023] The second housing 7 has a second frame member 8 and a second side plate 9 .

[0024] The second frame member 8 is composed of a frame that forms a rectangular parallelepiped shape. The second frame member 8 has openings on the side, top, and bottom surfaces of the rectangular parallelepiped shape. The frame that forms the second frame member 8 is made of sheet metal, for example, a rod-shaped rectangular flat plate that has been bent into an L shape in the short direction.

[0025] The second side plate 9 is attached to a side surface of the second frame member 8 and fixed with fixing screws 33. As shown in FIG. 3, the second side plate 9 is attached to one of the multiple side surfaces of the rectangular parallelepiped second frame member 8. Note that FIG. 3 is a schematic view, and components other than the illustrated second side plate 9 and second frame member 8 are not shown. Note that the second frame member 8 and the second side plate 9 may be fixed with fixing screws provided in four locations, as in the case of the first housing 1 shown in FIG. 5, but are not limited to this and may be provided in more than four locations.

[0026] Similar to the first side panel 3 shown in Fig. 4, the second side panel 9 is configured to be detachable from the second frame member 8. The second side panel 9 has a second convex portion 10 that protrudes outward from the second frame member 8 and a second flat portion 12. Similar to the first concave portion 4, the second convex portion 10 is formed, for example, by pressing a mold against a flat plate and performing a bending process. The second flat portion 12 is a flat portion of the second side panel 9 other than the area where the second convex portion 10 is formed.

[0027] The second protrusion 10 is formed on the second side panel 9 so that the cross-sectional shape of the second protrusion 10 when cut on a plane parallel to the floor 29 is the same at any cross-sectional position in the vertical direction. Furthermore, by making the cross-sectional shapes of the first recess 4 and the second protrusion 10 the same, the first recess 4 and the second protrusion 10 are mated, and the first housing 1 and the second housing 7 are connected. When the first recess 4 and the second protrusion 10 are mated, a gap 16 is formed between the first recess 4 and the second protrusion 10.

[0028] As will be described later, the second protrusion 10 is formed to have a cross-sectional shape that is slightly smaller than the first recess 4. Furthermore, although the case where the first recess 4 and the second protrusion 10 have the same cross-sectional shape has been described, the first recess 4 and the second protrusion 10 may have different shapes as long as they can be fitted together. For example, the cross-sectional shape of the first recess 4 may be circular, and the cross-sectional shape of the second protrusion 10 may be hexagonal.

[0029] Figure 8 is a schematic cross-sectional view of the board device 100 taken along the line AA in Figure 1. Figure 8 shows a schematic cross-sectional view of the first side plate 3 and the second side plate 9, and does not show the cross-sections of the first frame member 2 and the second frame member 8. The first recess 4 of the first side plate 3 is fitted into and connected to the second protrusion 10 of the second side plate 9.

[0030] The fourth side plate is a flat plate and is attached to one of the multiple side surfaces of the first frame member 2 other than the side surface to which the first side plate 3 is attached. As shown in Fig. 8, a fourth side plate 17, which is a flat plate, is provided on the side surface of the first housing 1 other than the side surface to which the first side plate 3 is provided. However, a door that can be opened and closed freely may be attached instead of the fourth side plate 17.

[0031] The fifth side plate 21 is a flat plate and is attached to one of the multiple side surfaces of the second frame member 8 other than the side surface to which the second side plate 9 is attached. As shown in Fig. 8, the fifth side plate 21, which is a flat plate, is provided on the side surface of the second housing 7 other than the side surface to which the second side plate 9 is provided. However, a door that can be opened and closed freely may be attached instead of the fifth side plate 17.

[0032] As described above, the gap 16 is a space formed between the first recess 4 and the second protrusion 10 when they are mated. FIG. 9 is a schematic cross-sectional view of range D in FIG. 8, omitting parts other than the mating location. Cr in FIG. 9 is the size of the gap 16. Cr is preferably as small as possible within a range exceeding 0 mm and equal to or less than the plate thickness of the first side plate 3 or the second side plate 9. If the protruding height of the second protrusion 10 is L4 and the width of the second protrusion 10 is L5, the dimensions of the second protrusion 10 are, for example, L4 = 30 mm and L5 = 30 mm.

[0033] 9, the first inclination angle 30 is the angle formed between the plane of the first flat portion 6 and the side of the portion of the first recessed portion 4 that protrudes inward. The second inclination angle is also the angle formed between the plane of the second flat portion 12 and the side of the portion of the second protruding portion 10 that protrudes outward. The first inclination angle 30 is formed as a right angle or an obtuse angle, and the second inclination angle is also formed as a right angle or an obtuse angle.

[0034] Next, a method for installing the panel unit 100 according to the first embodiment will be described. The first housing 1 is first lifted by a crane and then placed at a predetermined position above the under-panel duct 27. The second housing 7 is then lifted by a crane and lowered from above so that the second housing 7 touches the upper surface of the under-panel duct 27. When the second housing 7 is lowered, the position of the second housing 7 being lifted by the crane is adjusted so that the first recess 4 and the second protrusion 10 fit together. The first housing 1 and the second housing 7 are mated and connected by inserting the second protrusion 10 into the first recess 4. Note that the first housing 1 and the second housing 7 can be connected simply by inserting the second protrusion 10 into the first recess 4; they do not necessarily need to be fastened together by a fastening means such as a screw. In this way, no additional connecting work is required other than the mating work performed when the second housing 7 is lowered by a crane or the like, and the first housing 1 and the second housing 7 can be easily connected. Alternatively, the second housing 7 may be fixed to the under-board duct 27 first, and then the first housing 1 may be fitted into the second housing 7 while adjusting its position using a crane or the like.

[0035] Next, we will explain the vibration damping operation of the thus configured board device 100. As shown in Figure 8, the first housing 1 and the second housing 7 are connected by the first recess 4 and the second protrusion 10, so that the connection between the first housing 1 and the second housing 7 is easily maintained even when shaking such as an earthquake occurs, and the earthquake resistance of the board device 100 is improved.

[0036] As described above, the panel device 100 according to the first embodiment comprises a first housing 1 having a first frame member 2 forming a rectangular parallelepiped frame and a first side panel 3 attached to one of the multiple sides of the rectangular parallelepiped shape of the first frame member 2; a second housing 7 arranged adjacent to the first housing 1 and having a second frame member 8 forming a rectangular parallelepiped frame and a second side panel 9 attached to the side of the second frame member 8 facing the first side panel 3, the first side panel 3 having a first recess 4 protruding toward the inside of the first frame member 2, and the second side panel 9 having a second protrusion 10 protruding toward the outside of the second frame member 8; and the first housing 1 being connected to the second housing 7 by the first recess 4 and the second protrusion 10 being fitted together.

[0037] According to this configuration, the first housing 1 and the second housing 7 can be easily joined together, and the earthquake resistance of the board device 100 is improved.

[0038] Furthermore, in the panel device 100 according to the first embodiment, the first side plate 3 can be configured to be detachable from the first frame member 2.

[0039] Such a configuration provides the advantage that the board device 100 can be easily assembled.

[0040] Furthermore, in the panel device 100 of embodiment 1, the first frame member 2 has a cutout portion 26 formed in a part of the horizontal frame of the rectangular parallelepiped frame, and the first side panel 3 may be configured so that at least a part of the first recess 4 is inserted into the cutout portion 26.

[0041] According to this configuration, the first frame member 2 and the first side plate 3 do not interfere with each other, and the first housing 1 can be easily assembled.

[0042] <First Modification of First Embodiment> Next, a first modified example of the first embodiment will be described. Fig. 10 is an enlarged cross-sectional view of the portion where the first recess 4a and the second protrusion 10a are mated. In the first modified example, a modified cross-sectional shape of the first recess 4a and the second protrusion 10a will be described.

[0043] The first recess 4a is formed in the first side panel. As shown in Fig. 10, the cross section of the first recess 4a cut by a plane parallel to the floor 29 is formed as a hexagon. Here, the cross section of the first recess 4a can be formed as a polygon, may be a triangle, and is not limited to the exemplified rectangle and hexagon. The cross section of the first recess 4a may also be an arc shape.

[0044] The second protrusion 10a is formed on the second side panel. As shown in FIG. 10, the cross-sectional shape of the second protrusion 10a when cut along a plane parallel to the floor 29 is hexagonal, corresponding to the shape of the first recess 4a. The cross-sectional shape of the second protrusion 10a may be any shape that can fit into the first recess 4a, and may be polygonal, such as triangular, and is not limited to the exemplified quadrangle and hexagon. The cross-sectional shape of the second protrusion 10a may also be arc-shaped.

[0045] The third inclination angle 30a is the angle between the plane of the first flat portion 6a and the side of the portion of the first recessed portion 4a that protrudes inward. The fourth inclination angle is the angle between the plane of the second flat portion 12a and the side of the portion of the second protruding portion 10a that protrudes outward. In the first modification of the first embodiment, the third inclination angle 30a and the fourth inclination angle are both 90 degrees.

[0046] As described above, in the panel device 100a relating to the first variant of embodiment 1, the first recess 4a and the second protrusion 10a may each be configured so that their cross-sectional shapes when cut by a plane parallel to the floor 29 are polygonal.

[0047] According to this configuration, the first side plate and the second side plate can be manufactured using molds of various shapes.

[0048] <Second Modification of First Embodiment> Next, a second modified example of the first embodiment will be described with reference to Fig. 11. Fig. 11 is a schematic cross-sectional view of a board device 100b according to the second modified example at a cross-sectional position at the same height as the AA cross-sectional position. In the second modified example of the first embodiment, a modified example in which recesses or protrusions are provided on unconnected side plates will be described.

[0049] The first side plate has a first recess 4b and a first flat portion 6b. The second side plate 9b has a second protrusion 10b and a second flat portion 12b. As shown in Fig. 11, the first recess 4b and the second protrusion 10b are fitted together, thereby connecting the first housing 1b and the second housing 7b.

[0050] 11, the fourth side plate 17a is attached to one of the rectangular side surfaces of the first housing 1b, which faces the first side plate. A fourth flat portion 20 and a fifth protrusion 19 are formed on the fourth side plate 17a. A fifth recess (not shown) may also be formed on the fourth side plate 17a.

[0051] 11, the fifth side plate 21a is a side plate attached to one of the side surfaces of the rectangular second housing 7b that faces the second side plate. The fifth side plate 21a is formed with a fifth flat portion 24 and a sixth recessed portion 22. The fifth side plate 21a may also be formed with a sixth protruding portion (not shown).

[0052] The cross-sectional shapes of the fifth recess, fifth protrusion 19, sixth recess 22, and sixth protrusion when cut by a plane parallel to floor 29 are trapezoidal, but are not limited to this and may be polygonal such as triangular or arc-shaped.

[0053] Next, earthquake-resistant operation will be described. The fourth side plate 17a, which has the fifth protrusion 19 formed thereon, has improved bending rigidity compared to a side plate made of a flat plate. Similarly, the fifth side plate 21a, which has the sixth recess 22 formed thereon, has improved bending rigidity compared to a side plate made of a flat plate. Therefore, even when shaking occurs due to an earthquake or the like, side plates having recesses or protrusions are less likely to deform.

[0054] As described above, in the panel device 100b according to the second variant of embodiment 1, the first housing 1b, which is configured in a rectangular shape, may have side panels having recesses or protrusions provided on each of multiple side surfaces.

[0055] This configuration allows the first housing 1b and the second housing 7b to be easily joined together, and also has the effect of making the side panels of the board device 100b less likely to deform even when shaking occurs due to an earthquake or the like.

[0056] Embodiment 2 Board devices 100c1 and 100c2 according to a second embodiment will be described with reference to FIGS. 12 and 13. FIG. 12 is a schematic cross-sectional view of board device 100c1 at the same height as the AA cross-section. FIG. 13 is a schematic cross-sectional view of board device 100c2 at the same height as the AA cross-section. In the board device 100 according to the first embodiment, the first side plate 3 has one first recess 4 on the flat plate, and the second side plate 9 has one second protrusion 10 on the flat plate, and the first housing 1 and the second housing 7 are connected together. In the second embodiment, modifications of the first side plate and the second side plate will be described. The following description will focus on differences from the first embodiment, and descriptions of identical or corresponding parts will be omitted as appropriate.

[0057] As shown in Fig. 12, the first side panel of the board device 100c1 has a first recess 4c, a third protrusion 5, and a first flat portion. The third protrusion 5 protrudes toward the outside of the first frame member. When the first recess 4c and the third protrusion 5 are formed on the first side panel, the first flat portion is a flat portion of the first side panel other than the areas where the first recess 4c and the third protrusion 5 are formed.

[0058] As shown in Fig. 12, the second side panel of the board device 100c1 has a second protrusion 10c, a fourth recess 11, and a second flat portion. The fourth recess 11 protrudes toward the inside of the second frame member. When the second side panel has the second protrusion 10c and the fourth recess 11 formed therein, the second flat portion is a flat portion of the second side panel other than the areas where the second protrusion 10c and the fourth recess 11 are formed.

[0059] 12, the first side plate has one first recess 4c and two third protrusions 5. The second side plate has one second protrusion 10c and two fourth recesses 11.

[0060] Here, the number of first recesses 4c on the first side plate does not necessarily have to be the same as the number of second protrusions 10c on the second side plate, or the number of third protrusions 5 on the first side plate does not necessarily have to be the same as the number of fourth recesses 11 on the second side plate. For example, the number of first recesses 4c on the first side plate may be greater than or equal to the number of second protrusions 10c on the second side plate. Similarly, the number of third protrusions 5 on the first side plate may be greater than or equal to the number of fourth recesses 11 on the second side plate.

[0061] As described above, in the panel device 100c of embodiment 2, the first side panel 3c further has a third protrusion 5 protruding toward the outside of the first frame member 2b, and the second side panel 9c further has a fourth recess 11 protruding toward the inside of the second frame member 8b, and the first housing 1c may be configured to be connected to the second housing 7c by not only fitting the first recess 4c and the second protrusion 10c, but also by further fitting the third protrusion 5 and the fourth recess 11.

[0062] According to this configuration, the first housing 1c and the second housing 7c can be easily joined together, and the earthquake resistance of the board device 100c is improved.

[0063] <First Modification of Second Embodiment> Next, a board device 100d according to a first modification of the second embodiment will be described with reference to Fig. 14.
