FIG. 9 is an enlarged cross-sectional view of a portion where the first recess 4 and the second protrusion 10 of the panel device 100 according to Embodiment 1 are fitted together.

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

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

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

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

[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 surface, upper surface, and lower surface of the rectangular parallelepiped shape respectively. The frame forming the first frame member 2 is, for example, a sheet metal obtained by bending a rod-shaped rectangular flat plate into an L shape in the short side direction. Note that the first frame member 2 has a notch 26 so that the first side plate 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 the 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 plurality of side surfaces of the rectangular parallelepiped-shaped first frame member 2. Note that FIG. 2 is a schematic diagram, and parts other than the illustrated first side plate 3 and first frame member 2 are not shown. Note that the fixing screws 33 for fixing the first frame member 2 and the first side plate 3 are provided at four locations in FIG. 5, but this is not limiting, and they may be provided at more than four locations. Also, 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 plate 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 plate 3 such that the cross-sectional shape of the first recess 4 when cut by 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 plate 3 outside the range where the first recess 4 is formed. Note that the first recess 4 shown in FIG. 4 is formed along the vertical direction from the lower end to the upper end of the flat plate, but is not necessarily limited to this shape and may be formed in a part of the flat plate. Further, as shown in FIG. 9, the first inclination angle 30 is an angle formed by the plane of the first flat portion 6 and the side of the portion protruding toward the inside of the first recess 4. Details of the first inclination angle 30 will be described later.

[0019] As shown in FIGS. 5 and 6, the notch 26 is formed in a part of the horizontal frame of the frame of the first frame member 2 that forms a rectangular parallelepiped shape. Here, FIG. 6 is an enlarged side view of the notch in the range B shown in FIG. 5, and the side plates on the upper surface of the first housing 1 and the first side plate 3 are not shown. The dotted line in FIG. 6 is a hidden line showing a part of the first frame member 2 bent in the depth direction (horizontal direction) of the paper surface. FIG. 7 shows a cross-sectional view of the first frame member 2 as viewed from the direction indicated by the arrow in the figure at the C-C cross-sectional position shown in FIG. 6. In FIG. 7, the first side plate 3 is not shown. 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 of a sheet metal obtained by bending a rod-shaped rectangular flat plate into an L shape in the short side direction. Further, as described above, among the sides forming the rectangular frame of the first frame member 2, the upper and lower sides of the side surface to which the first side plate 3 is attached are provided with notches 26.

[0021] Here, a schematic procedure for manufacturing the side of the first frame member 2 having the notch 26 will be described. First, the flat plate that serves as the base of the frame of the first frame member 2 is a rod-shaped rectangular flat plate, and the plate material at the location corresponding to the notch portion is cut partially in a square shape and removed. After the removal process, the flat plate is bent and a 90-degree angle is imparted. In this way, an L-shaped frame having the notch 26 is manufactured.

[0022] In FIGS. 6 and 7, lengths L1, L2, and L3 are shown, and the lengths L1, L2, and L3 are dimensions around the notch of the first frame member. The length L1 corresponds to the length of the portion removed by the above-described removal process in the short side direction of the rectangular flat plate when the frame forming the first frame member 2 is a rod-shaped rectangular flat plate. In FIG. 7, in the cross-section of the L-shaped frame, the length L2 from the position of the base on the inner circumferential side bent at a right angle to the edge of the removed portion is larger than the plate thickness L3 of the flat plate that serves as the base of the frame of the first frame member 2. Since L2 is larger than L3, it becomes easier to perform a bending process at a right angle on the removed flat plate. When the first side plate 3 is attached to the first frame member 2, as shown in FIGS. 2 and 5, the upper and lower portions, which are part of the first recess 4 of the first side plate 3, are inserted into the notch 26. By forming the notch 26 in the first frame member 2, the first recess 4 can be attached without interfering with the first frame member 2.

[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 forming a rectangular parallelepiped shape. The second frame member 8 has openings on the side surface, upper surface, and lower surface of the rectangular parallelepiped shape. The frame forming the second frame member 8 is composed of, for example, sheet metal obtained by bending a rod-shaped rectangular flat plate into an L shape in the short side direction.

[0025] The second side plate 9 is attached to the 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 plurality of side surfaces of the rectangular parallelepiped-shaped second frame member 8. Note that FIG. 3 is a schematic view, and parts other than the illustrated second side plate 9 and second frame member 8 are not shown. The second frame member 8 and the second side plate 9 may be fixed by four fixing screws as in the case of the first housing 1 shown in FIG. 5, and are not limited thereto, and may be further provided at locations other than four.

[0026] Similar to the first side plate 3 shown in FIG. 4, the second side plate 9 is configured to be detachable from the second frame member 8. The second side plate 9 has a second convex portion 10 and a second flat portion 12 that protrude outward from the second frame member 8. The second convex portion 10 is formed, for example, by pressing a mold against a flat plate and bending it, similar to the first concave portion 4. The second flat portion 12 is a flat portion of the second side plate 9 outside the range where the second convex portion 10 is formed.

[0027] The second convex portion 10 is formed on the second side plate 9 such that the cross-sectional shape of the second convex portion 10 when cut by a plane parallel to the floor 29 is the same at any cross-sectional position in the vertical direction. Also, by making the cross-sectional shapes of the first concave portion 4 and the second convex portion 10 similar, the first concave portion 4 and the second convex portion 10 are fitted together, and the first housing 1 and the second housing 7 are connected. When the first concave portion 4 and the second convex portion 10 are fitted together, a gap 16 is formed between the first concave portion 4 and the second convex portion 10.

[0028] Note that, as will be described later, the second convex portion 10 is formed to have a cross-sectional shape that is slightly smaller than that of the first concave portion 4. Also, although the case where the cross-sectional shapes of the first concave portion 4 and the second convex portion 10 are the same has been described, it is sufficient that the first concave portion 4 and the second convex portion 10 can be fitted together, and they are not limited to the same shape and may have different shapes. For example, the cross-sectional shape of the first concave portion 4 may be circular and the cross-sectional shape of the second convex portion 10 may be hexagonal.

[0029] FIG. 8 is a schematic cross-sectional view of the board device 100 at the A-A cross-sectional position of FIG. 1. In FIG. 8, schematic cross-sectional views of the first side plate 3 and the second side plate 9 are shown, and illustrations of the cross-sections of the first frame member 2 and the second frame member 8 are omitted. The first concave portion 4 of the first side plate 3 is fitted and connected to the second convex portion 10 of the second side plate 9.

[0030] The fourth side plate is a flat plate and is attached to a side surface of the plurality of 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, in the first housing 1, a fourth side plate 17, which is a flat plate, is provided on a side surface other than the side surface on which the first side plate 3 is provided. However, a door that can be opened and closed may be attached instead of the fourth side plate 17.

[0031] The fifth side plate 21 is a flat plate and is attached to a side surface of the plurality of 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, in the second housing 7, a fifth side plate 21, which is a flat plate, is provided on a side surface other than the side surface on which the second side plate 9 is provided. However, a door that can be opened and closed may be attached instead of the fifth side plate 17.

[0032] As described above, the gap 16 is a space formed between the first concave portion 4 and the second convex portion 10 when the first concave portion 4 and the second convex portion 10 are fitted. FIG. 9 is a schematic cross-sectional view in the range D of FIG. 8, and portions other than the fitting portion are omitted. Cr shown in FIG. 9 is the size of the gap 16. Cr is preferably as small as possible within a range that exceeds 0 mm and is 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 convex portion 10 is L4 and the width of the second convex portion 10 is L5, the dimensions of the second convex portion 10 are, for example, L4 = 30 mm and L5 = 30 mm.

[0033] As shown in FIG. 9, the first inclination angle 30 is the angle formed by the plane of the first flat portion 6 and the side of the portion protruding toward the inside of the first concave portion 4. The second inclination angle is also the angle formed by the plane of the second flat portion 12 and the side of the portion protruding toward the outside of the second convex portion 10. The first inclination angle 30 is formed as a right angle or an obtuse angle, and the second inclination angle is similarly formed as a right angle or an obtuse angle.

[0034] Next, a method for installing the board device 100 according to the first embodiment will be described. After the first housing 1 is first lifted by a crane, it is installed at a predetermined position on the under-board duct 27. Next, the second housing 7 is lifted by a crane and lowered from above downward. As a result, the second housing 7 comes into contact with the upper surface of the under-board duct 27. When lowering the second housing 7, the position of the second housing 7 lifted by the crane is adjusted so that the first concave portion 4 and the second convex portion 10 are fitted together. The first housing 1 and the second housing 7 are fitted and connected by inserting the second convex portion 10 into the first concave portion 4. Note that the connection between the first housing 1 and the second housing 7 only needs to be fitted by simply inserting the second convex portion 10 into the first concave portion 4, and the two do not necessarily have to be joined by fixing means such as screws. In this way, since there is no operation of connecting other than the fitting operation during lowering by a crane or the like, the first housing 1 and the second housing 7 can be easily connected. Further, after the second housing 7 is first fixed to the under-board duct 27, the first housing 1 may be fitted to the second housing 7 while adjusting the position with a crane or the like.

[0035] Next, the vibration damping operation in the board device 100 configured as described above will be described. The first housing 1 and the second housing 7 connected as shown in FIG. 8 are fitted together by the first concave portion 4 and the second convex portion 10. Even when shaking such as an earthquake occurs, the connection between the first housing 1 and the second housing 7 is easily maintained, and the seismic resistance of the board device 100 is improved.

[0036] As described above, in the board device 100 according to the first embodiment, the first housing 1 includes a first frame member 2 that forms a rectangular parallelepiped-shaped frame, and a first side plate 3 attached to one of the plurality of side surfaces of the rectangular parallelepiped shape in the first frame member 2. The second housing 7 is disposed adjacent to the first housing 1 and includes a second frame member 8 that forms a rectangular parallelepiped-shaped frame, and a second side plate 9 attached to a side surface of the rectangular parallelepiped shape in the second frame member 8 that faces the first side plate 3. The first side plate 3 has a first concave portion 4 that protrudes toward the inside of the first frame member 2, and the second side plate 9 has a second convex portion 10 that protrudes toward the outside of the second frame member 8. The first housing 1 is connected to the second housing 7 by fitting the first concave portion 4 and the second convex portion 10 together.

[0037] According to such a configuration, the first housing 1 and the second housing 7 can be easily fitted together, and the effect of improving the seismic resistance of the board device 100 can be obtained.

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

[0039] According to such a configuration, the effect that the board device 100 can be easily assembled can be obtained.

[0040] Further, in the board device 100 according to the first embodiment, the first frame member 2 has a notch portion 26 that is a notch in a part of the horizontal frame of the rectangular parallelepiped-shaped frame, and the first side plate 3 may be configured such that at least a part of the first concave portion 4 is inserted into the notch portion 26.

[0041] According to such a configuration, the effect that the first housing 1 can be easily assembled without interference between the first frame member 2 and the first side plate 3 can be obtained.

[0042] <First Modification Example of Embodiment 1> Next, a first modification of Embodiment 1 will be described. FIG. 10 is an enlarged cross-sectional view of a portion where the first concave portion 4a and the second convex portion 10a are fitted together. In the first modification, a modification of the cross-sectional shapes of the first concave portion 4a and the second convex portion 10a will be described.

[0043] The first concave portion 4a is formed in the first side plate. As shown in FIG. 10, the first concave portion 4a has a hexagonal cross-sectional shape formed by a plane parallel to the floor 29. Here, the cross-sectional shape of the first concave portion 4a can be formed as a polygon, may be a triangle, and is not limited to the illustrated quadrilateral and hexagon. Also, the cross-sectional shape of the first concave portion 4a may be an arc shape.

[0044] The second convex portion 10a is formed in the second side plate. As shown in FIG. 10, the cross-sectional shape of the second convex portion 10a when cut by a plane parallel to the floor 29 is formed as a hexagon corresponding to the shape of the first concave portion 4a. Here, the cross-sectional shape of the second convex portion 10a only needs to be a shape that can be fitted with the first concave portion 4a, may be formed as a polygon, for example, may be a triangle, and is not limited to the illustrated quadrilateral and hexagon. Also, the cross-sectional shape of the second convex portion 10a may be an arc shape.

[0045] The third inclination angle 30a is an angle formed by the plane of the first flat portion 6a and the side of the portion protruding toward the inside of the first concave portion 4a. Also, the fourth inclination angle is an angle formed by the plane of the second flat portion 12a and the side of the portion protruding toward the outside of the second convex portion 10a. In the case of the first modification of Embodiment 1, both the third inclination angle 30a and the fourth inclination angle are 90 degrees.

[0046] As described above, in the board device 100a according to the first modification of Embodiment 1, the first concave portion 4a and the second convex portion 10a may be configured such that their cross-sectional shapes when cut by a plane parallel to the floor 29 are each formed as a polygon.

[0047] According to such a configuration, an effect is obtained that the first side plate and the second side plate can be manufactured using molds of various shapes.

[0048] <Second Modification Example of Embodiment 1> Next, a second modification example of Embodiment 1 will be described with reference to FIG. 11. FIG. 11 is a schematic cross-sectional view at a cross-sectional position at the same height as the A-A cross-sectional position of the board device 100b according to the second modification example. In the second modification example of Embodiment 1, a modification example in which a concave portion or a convex portion is provided on the unconnected side plate will be described.

[0049] The first side plate has a first concave portion 4b and a first flat portion 6b. The second side plate 9b has a second convex portion 10b and a second flat portion 12b. As shown in FIG. 11, the first housing 1b and the second housing 7b are connected by fitting the first concave portion 4b and the second convex portion 10b together.

[0050] The fourth side plate 17a is a side plate attached to the side surface of the first housing 1b having a rectangular shape and facing the first side plate, as shown in FIG. 11. A fourth flat portion 20 and a fifth convex portion 19 are formed on the fourth side plate 17a. Further, a fifth concave portion (not shown) may be formed on the fourth side plate 17a.

[0051] The fifth side plate 21a is a side plate attached to the side surface of the second housing 7b having a rectangular shape and facing the second side plate, as shown in FIG. 11. A fifth flat portion 24 and a sixth concave portion 22 are formed on the fifth side plate 21a. Further, a sixth convex portion (not shown) may be formed on the fifth side plate 21a.

[0052] The cross-sectional shape of the fifth concave portion, the fifth convex portion 19, the sixth concave portion 22, and the sixth convex portion when cut by a plane parallel to the floor 29 is a trapezoidal shape, but is not limited thereto, and may be a polygon such as a triangle or an arc shape.

[0053] Next, the seismic operation will be described. The fourth side plate 17a formed with the fifth convex portion 19 has improved bending rigidity compared to a side plate composed of a flat plate. Similarly, the fifth side plate 21a formed with the sixth concave portion 22 has improved bending rigidity compared to a side plate composed of a flat plate. Therefore, even when shaking occurs due to an earthquake or the like, the side plates having concave or convex portions are less likely to deform.

[0054] As described above, in the board device 100b according to the second modification of the first embodiment, on the side surface of the first housing 1b having a rectangular shape, side plates having concave or convex portions may be provided on a plurality of side surfaces respectively.

[0055] According to such a configuration, the first housing 1b and the second housing 7b can be easily fitted together, and further, an effect is obtained in that the side plates of the board device 100b are less likely to deform even when shaking such as an earthquake occurs.

[0056] Embodiment 2. The board devices 100c1 and c2 according to the second embodiment will be described with reference to FIGS. 12 and 13. FIG. 12 is a schematic cross-sectional view at a cross-sectional position at the same height as the A-A cross-sectional position of the board device 100c1. FIG. 13 is a schematic cross-sectional view at a cross-sectional position at the same height as the A-A cross-sectional position of the board device 100c2. In the board device 100 according to the first embodiment, the case where the first housing 1 and the second housing 7 are connected was described assuming that the first side plate 3 has one first concave portion 4 in a flat plate and the second side plate 9 has one second convex portion 10 in a flat plate. In the second embodiment, modified examples of the first side plate and the second side plate will be described. The following description will focus on the differences from the first embodiment, and descriptions of the same or corresponding parts will be omitted as appropriate.

[0057] As shown in FIG. 12, the first side plate of the board device 100c1 has a first concave portion 4c, a third convex portion 5, and a first flat portion. The third convex portion 5 protrudes toward the outside of the first frame member. When the first concave portion 4c and the third convex portion 5 are formed on the first side plate, the first flat portion is a flat portion outside the range where the first concave portion 4c and the third convex portion 5 are formed on the first side plate.

[0058] As shown in FIG. 12, the second side plate of the disk device 100c1 has a second convex portion 10c, a fourth concave portion 11, and a second flat portion. The fourth concave portion 11 protrudes toward the inside of the second frame member. When the second convex portion 10c and the fourth concave portion 11 are formed on the second side plate, the second flat portion is a flat portion other than the range where the second convex portion 10c and the fourth concave portion 11 are formed on the second side plate.

[0059] In the case shown in FIG. 12, the first side plate has one first concave portion 4c and two third convex portions 5. The second side plate has one second convex portion 10c and two fourth concave portions 11.

[0060] Here, the number of the first concave portions 4c of the first side plate and the number of the second convex portions 10c of the second side plate, or the number of the third convex portions 5 of the first side plate and the number of the fourth concave portions 11 of the second side plate do not necessarily have to match. For example, the number of the first concave portions 4c of the first side plate may be formed on the first side plate to be equal to or more than the number of the second convex portions 10c of the second side plate. Similarly, the number of the third convex portions 5 of the first side plate may be formed on the first side plate to be equal to or more than the number of the fourth concave portions 11 of the second side plate.
