[0004] [Patent Document 1] International Publication No. 2018 / 230161 Brochure Summary of the Invention [Problem to be solved by the invention]

[0005] However, with the technology described in Patent Document 1, lighting fixtures are installed on a lip portion formed by raising both widthwise edges of a steel plate on the tabletop and folding the opposing edges inward. Therefore, the technology described in Patent Document 1 has a problem in that it limits the lighting fixtures that can be installed on the tabletop, and for example, it is not possible to install lighting fixtures that require a relatively large installation area, such as LEDs.

[0006] In consideration of the above problems, the present invention aims to provide a car and elevator that can alleviate the restrictions on the lighting fixtures that can be installed. [Means for solving the problem]

[0007] To solve the above problems and achieve the present object, the elevator car includes a ceiling unit and side panels arranged around the ceiling unit. The ceiling unit includes a central top plate, side top plates, a flat cover, and a lighting fixture. The central top plate has a central top surface portion with a flat surface and is open on the upper side in the vertical direction. The side top plates are arranged on both sides of the central top plate, have side top surfaces with flat surfaces, and are open on the lower side in the vertical direction. The flat cover covers the opening in the central top plate. The lighting fixture is installed on the central top surface portion of the central top plate.

[0008] The elevator also includes a car that moves up and down within the elevator shaft. The car may be any of the above-described cars. [Effects of the Invention]

[0009] According to the car and elevator having the above configuration, restrictions on the lighting fixtures that can be installed can be alleviated. [Brief explanation of the drawings]

[0011] Hereinafter, a car and an elevator according to an embodiment will be described with reference to Fig. 1 to Fig. 5. In addition, common members in each figure are given the same reference numerals.

[0012] 1. Example of implementation 1-1. Example of car configuration First, the configuration of an elevator car according to an embodiment (hereinafter referred to as "this example") will be described with reference to FIG. FIG. 1 is a perspective view showing an elevator car of this example.

[0013] The elevator car 1 shown in Figure 1 moves up and down in a hoistway formed in a building structure. Note that elevators equipped with the car 1 may be of various types, such as a 1:1 roping elevator, a 2:1 roping elevator, a hydraulic elevator, or the like.

[0014] The car 1 is formed in a hollow, approximately rectangular parallelepiped shape. The car 1 includes a ceiling unit 2, a front panel 3 and a side panel 4 that surround the ceiling unit 2, and a floor surface that faces the ceiling unit 2 in the vertical direction. The side panels 4 are arranged on both sides of the ceiling unit 2 in the width direction that is perpendicular to the vertical direction. The front panel 3 is arranged on the front side in the front-to-rear direction that is perpendicular to the vertical direction of the ceiling unit 2 and also perpendicular to the width direction.

[0015] The front panel 3 is provided with a car door 5 that opens and closes the entrance to the car 1, and a door sill 6. The door sill 6 is disposed at the lower end of the front panel 3 in the up-and-down direction. The door sill 6 supports the car door 5 so that it can be opened and closed.

[0016] 1-2. Ceiling unit configuration example Next, the configuration of the ceiling unit 2 will be described with reference to FIGS. Fig. 2 is a plan view showing the ceiling unit 2, as seen from the arrow B shown in Fig. 1. Fig. 3 is an exploded perspective view showing the ceiling unit 2. Fig. 4 is a cross-sectional view showing the ceiling unit 2, as seen from the line AA shown in Fig. 1.

[0017] 2 to 4, the ceiling unit 2 has a first frame 21, a second frame 22, a plurality of flat covers 23, two side top panels 24, 24, a central top panel 25, a central reinforcing member 26, and a side reinforcing member 27. Also, as shown in Fig. 4, the ceiling unit 2 has a shielding plate 30 that serves as a design surface, a shielding plate holding member 33, a lighting fixture 34, and an on-car device 36.

[0018] As shown in Figures 2 and 3, the first frame 21 and the second frame 22 are arranged on both sides of the ceiling unit 2 in the front-to-rear direction. The first frame 21 is arranged on the rear side of the ceiling unit 2 in the front-to-rear direction, and the second frame 22 is arranged on the front side of the ceiling unit 2 in the front-to-rear direction. The first frame 21 and the second frame 22 face each other in the front-to-rear direction. The first frame 21 and the second frame 22 extend along the width direction of the ceiling unit 2. Between the first frame 21 and the second frame 22, a plurality of flat covers 23, two side top plates 24, 24, a central top plate 25, a central reinforcing member 26, and a side reinforcing member 27 are arranged.

[0019] The two side top plates 24, 24 are disposed on both sides in the width direction of the ceiling unit 2. The central top plate 25 is disposed in the center in the width direction of the ceiling unit 2. In other words, the central top plate 25 is disposed between the two side top plates 24, 24.

[0020] The side top panels 24 and the central top panel 25 are formed by bending a flat plate-like member. The side top panel 24 has a side top surface portion 24a, a side surface portion 24b, an opposing edge portion 24c, and a fixing surface portion 24g. The side top surface portion 24a is formed in a substantially rectangular shape with a flat surface. The side top surface portion 24a extends along the front-to-rear direction of the ceiling unit 2.

[0021] A side surface portion 24b is formed at one end in the width direction of the side top surface portion 24a, and an opposing edge portion 24c is formed at the other end in the width direction of the side top surface portion 24a. The side surface portion 24b is located on the outer side in the width direction of the ceiling unit 2, and the opposing edge portion 24c is located on the center side in the width direction of the ceiling unit 2.

[0022] The side surface portion 24b protrudes downward in the vertical direction from the end of the side top surface portion 24a. Similarly, the opposing edge portion 24c protrudes downward in the vertical direction from the end of the side top surface portion 24a. The side surface portion 24b and the opposing edge portion 24c face each other in the width direction of the ceiling unit 2. As shown in FIG. 4, an opening 24d is formed between the side surface portion 24b and the opposing edge portion 24c on the lower side in the vertical direction of the side top plate 24. In other words, the lower side of the side top plate 24 is open in the vertical direction. The vertical length of the opposing edge portion 24c is set to be shorter than the vertical length of the side surface portion 24b.

[0023] Furthermore, the lower end in the vertical direction of the side surface portion 24b is connected to the upper end in the vertical direction of the side panel 4 of the car 1. The side top plate 24 is formed integrally with the side frame of the ceiling unit 2 and the top plate by the side top surface portion 24a and the side surface portion 24b. This makes it possible to reduce the number of parts.

[0024] Furthermore, a side reinforcing member 27 and an over-car device 36 are disposed in the opening 24d in the top side panel 24. That is, the side reinforcing member 27 and the over-car device 36 are disposed between the side surface 24b and the opposing edge 24c. The side reinforcing member 27 is open at the top in the vertical direction and protrudes downward in the vertical direction. This side reinforcing member 27 is fixed to the top side surface 24a. By disposing the side reinforcing member 27 on the top side panel 24, the strength of the ceiling unit 2 can be increased.

[0025] Furthermore, the car-mounted device 36 and the side reinforcing member 27 can be stored inside the side top panel 24. This prevents the car-mounted device 36 from protruding upward from the top surface of the ceiling unit 2 in the vertical direction.

[0026] As the on-car device 36, for example, a camera, a speaker, an air purifier, and various other devices are applied.

[0027] Furthermore, as described above, by forming the side frame and the top plate integrally, the edges connecting the side frame and the top plate can be omitted. This allows for an expansion of the space formed by the side top surface portions 24a, side surfaces 24b, and opposing edges 24c of the side top plate 24. As a result, space for storing the on-car device 36 can be secured.

[0028] Furthermore, the on-car device 36 can be disposed closer to the side surface 24b within the side top panel 24. In other words, the on-car device 36 can be prevented from protruding toward the center of the ceiling unit 2. As a result, the on-car device 36 can be prevented from blocking light from the lighting fixtures 34.

[0029] 3, fixing surfaces 24g are formed on both front-rear end portions of the side top surface 24a, the side surface 24b, and the opposing edge 24c. The fixing surfaces 24g are bent substantially perpendicularly from the ends of the side top surface 24a, the side surface 24b, and the opposing edge 24c. The fixing surfaces 24g face the first frame 21 and the second frame 22. The fixing surfaces 24g are fixed to the first frame 21 and the second frame 22 using fixing screws or the like.

[0030] Furthermore, fixing holes 24e are formed in the side top surface portion 24a, the side surface portion 24b, the opposing edge portion 24c, and the fixing surface portion 24g. Fixing bolts 32 are inserted into the fixing holes 24e to fasten and fix to other members.

[0031] A central top panel 25 is disposed between the opposing edge portions 24c of the two side top panels 24, 24. The central top panel 25 has a central top surface portion 25a, two edge portions 25b, a flange portion 25c, and a fixing surface portion 25g. The central top surface portion 25a is formed in a substantially rectangular shape with a flat surface. The side top surface portions 24a extend along the front-to-rear direction of the ceiling unit 2.

[0032] Edges 25b are formed on both widthwise ends of the central top surface 25a. The edges 25b protrude upward in the vertical direction from the ends of the central top surface 25a. Therefore, an opening 25d is formed between the two edges 25b on the upper vertical side of the central top plate 25. That is, the central top plate 25 is open on the opposite side from the side top plates 24, i.e., on the upper vertical side. The vertical length of the edges 25b is set shorter than the vertical length of the side surface portions 24b of the side top plates 24.

[0033] A central reinforcing member 26 is disposed in the space formed by the central top surface portion 25a and the two edge portions 25b of the central top plate 25. The central reinforcing member 26 is open at the bottom in the vertical direction and protrudes toward the top in the vertical direction. Therefore, the orientation of the central reinforcing member 26 is opposite to that of the side reinforcing members 27 in the vertical direction. Furthermore, by disposing the central reinforcing member 26 on the central top plate 25, the strength of the ceiling unit 2 can be ensured.

[0034] A flange portion 25c is formed on the end of edge portion 25b opposite central top surface portion 25a. Flange portion 25c is bent substantially perpendicularly from edge portion 25b. That is, flange portion 25c protrudes outward in the width direction from the end of edge portion 25b.

[0035] 3, fixing surface portions 25g are formed on both ends of the central top surface portion 25a and the edge portions 25b in the front-rear direction. The fixing surface portions 25g are bent substantially perpendicularly from the ends of the central top surface portion 25a and the edge portions 25b. The fixing surface portions 25g face the first frame 21 and the second frame 22. The fixing surface portions 25g are fixed to the first frame 21 and the second frame 22 using fixing screws or the like.

[0036] Furthermore, fixing holes 25e are formed in the central top surface portion 25a, the edge portion 25b, the flange portion 25c, and the fixing surface portion 25g, respectively. Fixing bolts 32 are inserted into the fixing holes 25e to fasten and fix the unit to other members.

[0037] In addition, multiple flat covers 23 are arranged to cover the opening 25d formed on the upper side of the central top plate 25 in the vertical direction. The multiple flat covers 23 are arranged side by side along the front-to-rear direction of the ceiling unit 2. The flat covers 23 are formed of flat plate-shaped members. The flat covers 23 cover the opening 25d of the central top plate 25, and the side top surface portions 24a of the side top plates 24 can flatten the upper surface of the ceiling unit 2 in the vertical direction. Furthermore, as described above, the car-mounted device 36 is stored within the side top plate 24. This eliminates members protruding upward from the upper surface of the ceiling unit 2. As a result, safety can be ensured when workers work on the upper surface of the ceiling unit 2.

[0038] 4, a plurality of lighting fixtures 34 are installed on the central top surface portion 25a of the central top plate 25 and the flat portions of the side reinforcing members 27. Furthermore, a shielding plate 30 is arranged facing the central top plate 25 and the two side top plates 24 of the ceiling unit 2 in the vertical direction. The shielding plate 30 is made of a material that can transmit light emitted from the lighting fixtures 34. The shielding plate 30 also serves as a light scattering plate that scatters the light emitted from the lighting fixtures 34 and supplies it into the car 1. The shielding plate 30 is held by a shielding plate holding member 33.

[0039] The shielding plate holding member 33 is formed by, for example, a combination of an L-shaped steel member and a channel steel member with a U-shaped cross section. The shielding plate holding member 33 is fixed to the upper end portion in the vertical direction of the side panel 4 or the lower end portion in the vertical direction of the side surface portion 24b of the side top plate 24.

[0040] As described above, by positioning central top plate 25 so that opening 25d of central top plate 25 faces upward, central top surface 25a can be used as an installation surface for installing lighting fixtures 34. This makes it possible to expand the installation surface for installing lighting fixtures 34. As a result, restrictions on the lighting fixtures 34 to be installed can be alleviated, and lighting fixtures 34 that require a wide installation surface, such as LEDs, can be installed.

[0041] Furthermore, the edge 25b of the central top plate 25 and the opposing edge 24c of the side top plate 24 are set to have shorter vertical lengths than the side surface 24b. This ensures sufficient space between the central top surface 25a of the central top plate 25 and the shielding plate 30. As a result, a large lighting fixture 34 can be easily installed.

[0042] Furthermore, the wiring 31 extending from the on-car devices 36 and lighting fixtures 34 arranged on both sides of the width of the ceiling unit 2 is arranged in the space formed by the central top surface portion 25a and two edge portions 25b of the central top plate 25. Furthermore, the opening 25d of the central top plate 25 is closed by the flat cover 23. Therefore, the wiring 31 is stored within the central top plate 25 and the flat cover 23. This prevents the wiring 31 from hanging down in the vertical direction from the central top plate 25 and casting a shadow in the light from the lighting fixtures 34. Furthermore, the wiring 31 is exposed from the upper surface portion of the ceiling unit 2, which prevents the feet of a worker from getting caught on the wiring 31 when working on the upper surface portion of the ceiling unit 2. As a result, a highly safe elevator car 1 can be provided.

[0043] 2. Variations Next, the configuration of a ceiling unit according to a modified example will be described with reference to FIG. FIG. 5 is a cross-sectional view showing a ceiling unit according to a modified example.

[0044] The ceiling unit 2B according to the modified example shown in Fig. 5 differs from the ceiling unit 2 according to the embodiment described above in the width direction of the car 1. Therefore, here, parts common to the ceiling unit 2 according to the embodiment are given the same reference numerals and redundant explanations will be omitted.

[0045] The ceiling unit 2B shown in Fig. 5 has a shorter length in the width direction of the car 1, i.e., a shorter width of the opening, than the ceiling unit 2 shown in Fig. 4. As shown in Fig. 5, the ceiling unit 2B has a plurality of flat covers 23, two side top plates 24B, 24B, a central top plate 25, and a central reinforcing member 26.

[0046] The side top panel 24B has a side top surface portion 24a, a side surface portion 24b, and an opposing edge portion 24c. The width of the side top surface portion 24a is set shorter than the width of the side top surface portion 24a shown in FIG. 4. In the ceiling unit 2B shown in FIG. 5, the side top panel 24B does not have a side reinforcing member 27. However, the space formed by the side top surface portion 24a, the side surface portion 24b, and the opposing edge portion 24c of the side top panel 24B is sufficient. Therefore, even in the ceiling unit 2B according to the modified example, the on-car device 36 can be easily stored within the side top panel 24B.

[0047] The rest of the configuration is the same as that of the ceiling unit 2 according to the embodiment described above, and therefore a description thereof will be omitted. The ceiling unit 2B according to this narrower variant can also achieve the same functions and effects as the ceiling unit 2 according to the embodiment described above.

[0048] The present invention is not limited to the embodiments described above and shown in the drawings, and various modifications can be made without departing from the spirit of the invention as set forth in the claims.

[0049] In this specification, the words "parallel" and "orthogonal" are used, but these do not mean only "parallel" and "orthogonal" in the strict sense, but also include "parallel" and "orthogonal" and may also mean a "substantially parallel" or "substantially orthogonal" state within a range in which the functions can be exerted.
