DETAILED DESCRIPTION

[0023] Below, refer to Figure 1 to Figure 6 The elevator car and the elevator according to the embodiment will be described. Note that the same reference numerals are given to common components in the drawings.

[0024] 1. Implementation Example

[0025] [elevator]

[0026] First, refer to Figure 1 The structure of an elevator according to an embodiment example (hereinafter referred to as “this example”) will be described.

[0027] Figure 1 This is a schematic structural diagram showing a structural example of the elevator of this example.

[0028] like Figure 1 As shown, the elevator 1 of this example is installed in an elevator path 110 formed in a building structure. The elevator 1 includes an elevator car 120 that performs an ascending and descending operation in the elevator path 110 and carries people and cargo, a sling 130, a counterweight 140, and a hoist 100.

[0029] The hoisting machine 100 is disposed on the ceiling of the hoisting path 110, and raises and lowers the elevator car 120 by winding the rope 130. In addition, a deflection pulley 150 to which the rope 130 is mounted is provided near the hoisting machine 100.

[0030] The elevator car 120 is mounted on one axial end of the suspension rope 130, and the counterweight 140 is mounted on the other axial end of the suspension rope 130. Therefore, the elevator car 120 is connected to the counterweight 140 via the suspension rope 130. When the hoist 100 is driven, the elevator car 120 and the counterweight 140 are moved up and down. Hereinafter, the direction in which the elevator car 120 and the counterweight 140 are moved up and down is referred to as the up and down direction.

[0031] It should be noted that the structure of the elevator 1 is not limited to the above-mentioned 1:1 rope-type elevator, and various other elevators such as a 2:1 rope-type elevator and a hydraulic elevator can be applied.

[0032] [Elevator car]

[0033] Next, refer to Figure 2 The structure of the elevator car 120 will be described.

[0034] Figure 2 It is a perspective view showing the interior of the elevator car 120 .

[0035] like Figure 2 As shown in FIG. 1 , the elevator car 120 includes a car room 121, a door unit 122, and a lighting device 10. Figure 1 as well as Figure 2 As shown, the cage 121 is formed in a hollow substantially rectangular parallelepiped shape. An entrance 124 with one side open is provided in the cage 121. People and goods enter and exit the internal space of the cage 121 through the entrance 124. A door unit 122 is provided at the entrance 124 so as to be openable and closable.

[0036] The car room 121 includes a car floor 127, side panels 126, and a ceiling 125. The car floor 127 is formed in a substantially rectangular shape. The side panels 126 are arranged around the car floor 127. An entrance 124 is formed in one of the side panels 126 surrounding the car floor 127.

[0037] The ceiling 125 is disposed vertically opposed to the car floor 127. The ceiling 125 is formed in a substantially rectangular shape similarly to the car floor 127. The lighting fixture 10 is provided on the ceiling 125. As the lighting fixture 10, various light sources such as fluorescent lamps, LEDs, and organic ELs are applied.

[0038] [ceiling]

[0039] Next, refer to Figures 3 to 6 The structure of the ceiling 125 will be described.

[0040] Figure 3 It is a perspective view showing the ceiling 125 . Figure 4 It is a perspective view showing a state where an upper cover 13 described later is removed from the ceiling 125 . Figure 5 as well as Figure 6 1 is a cross-sectional view showing the ceiling 125 .

[0041] like Figure 3 as well as Figure 4 As shown in FIG. 1 , the ceiling 125 includes a frame 4, a main body 8, and a lighting fixture 10. The frame 4 is disposed at the outer edge of the ceiling 125 so as to surround the four sides of the ceiling 125. Figure 5 as well as Figure 6 As shown, the frame 4 has a substantially U-shaped cross-section when cut in the vertical direction. A cable 22 electrically connected to the lighting fixture 10 is accommodated in the frame 4 .

[0042] The main body 8 is supported by the frame 4 at the lower part of the frame 4 in the vertical direction. The main body 8 protrudes downward from the frame 4 in the vertical direction. The main body 8 has a recessed portion 12, an upper cover 13, and a reinforcing member 15. The main body 8 is provided with a lighting fixture 10.

[0043] The recessed portion 12 showing the exterior part has a lower cover 12a and a flange portion 12b. The lower cover 12a becomes the exterior surface of the ceiling 125. The lower cover 12a is formed in a flat plate shape. An opening portion 12c is formed in the center of the lower cover 12a. The lighting fixture 10 is arranged in the opening portion 12c of the lower cover 12a. In addition, a flange portion 12b is formed on the outer edge of the lower cover 12a.

[0044] The flange 12b is formed by bending the outer edge of the lower cover 12a multiple times (twice in this example). In addition, a recessed portion that protrudes downward in the vertical direction of the lower cover 12a, which becomes the appearance surface, is formed in the recessed portion 12. The flange 12b protrudes outward from the outer edge of the lower cover 12a. The flange 12b is bonded and fixed to the upper cover 13 by means of an adhesive 17. It should be noted that the flange 12b can also be bonded and fixed to the frame 4 by means of an adhesive 17.

[0045] In addition, in this example, an example of using adhesive 17 to bond and fix the main body 8 and the frame 4 is described, but it is not limited to this, and various other fixing methods such as fastening and fixing using bolts, welding, etc. can also be applied. It should be noted that by using adhesive fixing using adhesive 17, not only can the main body 8 and the frame 4 be easily positioned, but also the fixing operation can be easily performed.

[0046] The upper cover 13 is formed in a flat plate shape. The upper cover 13 is disposed opposite to the lower cover 12a of the recessed portion 12 in the vertical direction. That is, the upper cover 13 is disposed so as to block the upper part of the recessed portion in the recessed portion 12 in the vertical direction. An opening 13c is formed in the center of the upper cover 13. The lighting fixture 10 is disposed in the opening 13c. The bracket 5 is bonded and fixed to the outer edge of the opening 13c by means of an adhesive 17.

[0047] The bracket 5 is arranged so as to surround the opening 13c in the upper surface of the upper cover 13 in the vertical direction. The bracket 5 has a substantially U-shaped cross-section when cut in the vertical direction, similarly to the frame 4. The cover 11 is fixed to the upper part of the bracket 5 in the vertical direction via fixing screws 21.

[0048] The cover 11 is formed in a flat plate shape and blocks the upper and lower openings 13c of the upper cover 13 and 12c of the lower cover 12a. The cover 11 also covers the upper and lower lighting fixture 10 provided in the main body 8.

[0049] In addition, the reinforcing member 15 is accommodated in the entire surface of the recessed portion of the sunken portion 12. The reinforcing member 15 is arranged between the lower cover 12a and the upper cover 13. The reinforcing member 15 is a corrugated plate formed by bending a flat plate-shaped member multiple times. The reinforcing member 15 has a plurality of convex portions 15a protruding upward in the vertical direction and a plurality of concave portions 15b protruding downward in the vertical direction. The plurality of convex portions 15a and the plurality of concave portions 15b are alternately and repeatedly formed.

[0050] The convex portion 15a is a protrusion extending in a direction perpendicular to the direction in which the convex portion 15a and the concave portion 15b are adjacent. In addition, the concave portion 15b is a groove extending in a direction perpendicular to the direction in which the convex portion 15a and the concave portion 15b are adjacent. The convex portion 15a is bonded and fixed to the upper cover 13 by means of an adhesive 17. The concave portion 15b is bonded and fixed to the lower cover 12a by means of an adhesive 17. Therefore, the upper portion (convex portion 15a) and the lower portion (concave portion 15b) of the reinforcing member 15 in the vertical direction are bonded and fixed to the upper cover 13 and the lower cover 12a by means of an adhesive 17.

[0051] By fixing the reinforcing member 15 with the adhesive 17, the thickness of the adhesive layer can be reduced compared to the double-sided tape. As a result, it is possible to suppress the displacement of the upper cover 13 and the reinforcing member 15, and the lower cover 12a and the reinforcing member 15 in the vertical direction and the horizontal direction. As a result, not only the positioning of the reinforcing member 15 relative to the upper cover 13 and the lower cover 12a can be easily performed, but also the fixing operation of the reinforcing member 15 can be easily performed.

[0052] As described above, the reinforcing member 15 is accommodated in the concave portion of the depressed portion 12, and the upper portion of the reinforcing member 15 in the vertical direction is blocked by the upper cover 13. That is, the main body 8 has a closed cross-sectional structure in which the reinforcing member 15 is arranged on the entire surface. In addition, the reinforcing member 15 is bonded and fixed to the upper cover 13 and the lower cover 12a by means of the adhesive 17. As a result, the depressed portion 12, the upper cover 13, and the reinforcing member 15 constituting the main body 8 can be fixed integrally.

[0053] Here, when a load is applied to the reinforcing member 15, the load applied to the reinforcing member 15 is transmitted to the upper cover 13 and the lower cover 12a via the plurality of convex portions 15a and the plurality of concave portions 15b. Therefore, the load applied to the reinforcing member 15 can be dispersed to the upper cover 13 and the lower cover 12a. As a result, it is possible to suppress the local stress concentration on the lower cover 12a, which becomes the appearance surface, and suppress the deformation of the lower cover 12a under the action of the load. It should be noted that the reinforcing member 15 can also be formed by a plurality of members, and there is a discontinuous part in a part. That is, as the reinforcing member 15, in order to transmit the applied load to the upper cover 13 and the lower cover 12a, it is sufficient to be fixed in the upper and lower directions by the upper cover 13 and the lower cover 12a. As a result, it is possible to disperse the local stress and suppress the deformation of the lower cover 12a, which becomes the appearance surface.

[0054] In addition, in the conventional ceiling reinforcement structure, since the reinforcement member is locally arranged, it is necessary to increase the rigidity of one reinforcement member. As a result, in the conventional elevator car ceiling, there is a problem that the weight of the entire ceiling increases due to the locally arranged reinforcement member.

[0055] In contrast, the ceiling 125 of this example is configured as a closed cross-section structure in which the sunken portion 12, the upper cover 13, and the reinforcing member 15 constituting the main body 8 are integrally fixed, so that the applied load is dispersed, thereby improving the rigidity of the ceiling 125 as a whole. As a result, not only the thickness of the reinforcing member 15 can be reduced, but also the thickness of the upper cover 13 and the thickness of the lower cover 12a can be reduced. In addition, by improving the rigidity of the main body 8, the thickness of the frame 4 supporting the main body 8 can also be reduced. As a result, the ceiling 125 can be made lighter.

[0056] It should be noted that the present invention is not limited to the embodiments described above and shown in the accompanying drawings, and various modifications can be made within the scope of the gist of the invention described in the technical claims.

[0057] In the above-described embodiment, the upper cover 13 and the lower cover 12a are each formed of a single flat plate-like member. However, the present invention is not limited thereto, and the upper cover 13 and the lower cover 12a may be formed of a plurality of flat plate-like members.

[0058] Furthermore, an example in which the lighting fixture 10 is arranged in the central part of the main body 8 is described, but the present invention is not limited thereto. For example, a plurality of lighting fixtures may be arranged in a dispersed manner in the main body 8. In this case, it is preferable to cut off a portion of the reinforcing member 15 at a location that interferes with the lighting fixture. Even when a portion of the reinforcing member 15 is cut off, the load applied to the reinforcing member 15 is dispersed to the upper cover 13 and the lower cover 12a. As a result, it is possible to suppress the stress concentration at the end of the reinforcing member 15, and suppress the deformation of the lower cover 12a that serves as the appearance surface.

[0059] It should be noted that, in this specification, words such as "parallel" and "orthogonal" are used, but they do not mean strictly "parallel" and "orthogonal", but may also be a state of "approximately parallel" or "approximately orthogonal" that includes "parallel" and "orthogonal" and is within the range that can exert its function.
