Description

Technical Field

[0001] This invention relates to elevators and elevator cars. Background Technology

[0002] Surveillance cameras are sometimes installed in elevator cars for purposes such as crime prevention. To capture the overall condition of the elevator car, these cameras are typically installed on the ceiling. However, if a surveillance camera is installed on the ceiling in a location easily visible to passengers, it can negatively impact the car's appearance.

[0003] Therefore, there are known cars that employ a so-called suspended ceiling, where the ceiling surface visible to passengers is positioned lower than the upper end of the side panels of the car (for example, see Patent Document 1). When the car has a suspended ceiling, a space recessed upwards from the ceiling surface (hereinafter also referred to as a "corner space") can be ensured on the inner side of the side panels and around the ceiling surface. Therefore, by placing the surveillance camera in the corner space, it is difficult for passengers to see the surveillance camera. Thus, the aesthetics of the car can be improved.

[0004] In addition, there are cases where suspended ceilings are used not only to make it difficult for passengers to see the surveillance cameras, but also for various reasons, such as to make it difficult for passengers to see the air vents and ventilation openings located on the ceiling of the car.

[0008] The problem that the invention aims to solve

[0009] However, in the prior art, in order to make the ceiling of the car a suspended ceiling, at least two components (brackets, joint frames, etc.) are installed at the upper end of the side panels, and these two components are used to support the top plate made of a shielding panel, etc. Furthermore, the prior art is a so-called double-layered ceiling with a lower top plate such as a shielding panel arranged below the upper top plate. In order to ensure the desired space between the upper and lower top plates, a spacer is mounted and fixed at the upper end of the side panel, and the upper top plate is installed on top of this spacer. Therefore, the prior art suffers from the difficulty of having a large number of components used to construct the ceiling of the car.

[0010] The present invention was made to solve the above-mentioned problems, and its object is to provide an elevator and a car that can reduce the number of components required to make the ceiling portion of the car a suspended ceiling.

Detailed Implementation

[0027] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. In this specification and the drawings, elements having substantially the same function or structure are labeled with the same symbols, and repeated descriptions are omitted.

[0028] <First Implementation Method>

[0029] Figure 1 This is a simplified diagram illustrating a structural example of an elevator according to the first embodiment.

[0030] like Figure 1 As shown, an elevator is installed on the lifting path of a building structure such as a high-rise building, and has a winch 1, a main rope 2, a car 3, a pair of car pulleys 4A and 4B, a counterweight 5, and a pulley 6.

[0031] The winch 1 is a device used to wind up the main rope 2 to raise and lower the car 3. The winch 1 is located at the top of the elevator shaft. One end and the other end of the main rope 2 are fixed to the top of the elevator shaft. The main rope 2 is wound around a pair of car pulleys 4A and 4B, the winch 1, and the pulley 6. The car 3 is guided by a guide rail (not shown) to rise and fall within the elevator shaft. The pair of car pulleys 4A and 4B are positioned below the car 3. The counterweight 5 is used to achieve mass balance with the car 3. The counterweight 5 rises and falls in the opposite direction to the car 3 when the main rope 2 is wound up by the winch 1. The pulley 6 rises and falls together with the counterweight 5.

[0032] Furthermore, the structure of the elevator is not limited to Figure 1 The structure shown can be adapted to various configurations.

[0033] Figure 2 This is a simplified perspective view showing the structure of the car according to the first embodiment.

[0034] In this embodiment, to clarify the positional relationship of each part of the car 3, when viewed from the elevator landing side, the left-right direction of the car 3 is designated as the X direction, the depth direction of the car 3 as the Y direction, and the height direction of the car 3 as the Z direction. In the lifting path of the car 3, the X and Y directions are parallel to the horizontal direction, and the Z direction is parallel to the vertical direction.

[0035] The car 3 has a car compartment (not shown) that serves as a space for accommodating passengers and cargo. The car 3 has four side panels 11 (11a, 11b, 11c, 11d), a car door 12, a car floor 13, a car ceiling 14, and a car frame 15.

[0036] Four side panels 11 are configured to surround the car compartment. Two of the four side panels 11, 11a and 11b, are arranged in pairs on the left and right sides of the car 3. Furthermore, side panel 11c is located at the front of the car 3, and side panel 11d is located at the rear of the car 3. In the following description, without distinguishing between the individual side panels 11a, 11b, 11c, and 11d, they are collectively referred to as side panels 11.

[0037] A car door 12 is provided at the front of the car 3. The car door 12 is a door that opens and closes as an entrance to the car compartment leading to the car 3. The side panel 11c is located at the front of the car 3, above the car door 12. Furthermore, a sill 16 is installed at the front of the car 3, below the car door 12. A guide groove 16a is formed in the sill 16. The car door 12 is guided by the guide groove 16a of the sill 16 to open and close in the X direction.

[0038] The car floor 13 is located at the bottom of the car 3. Although not shown, the car floor 13 has a base for carrying passengers and goods and a support mechanism for supporting the base.

[0039] The car roof 14 includes a roof panel 17 and a reinforcing frame 18. The roof panel 17 and the reinforcing frame 18 are described in detail below.

[0040] The car frame 15 consists of two longitudinal frames 15a and 15b, an upper frame 15c, and a lower frame (not shown). When viewed from direction A, the car frame 15 is arranged as a long rectangle. The two longitudinal frames 15a and 15b are arranged in pairs on the left and right sides of the car 3. The upper frame 15c is positioned at the top of the car 3, connecting the upper ends of the two longitudinal frames 15a and 15b. The lower frame is positioned at the bottom of the car 3, connecting the lower ends of the two longitudinal frames 15a and 15b.

[0041] Next, the structure of the top plate 17 and the reinforcing frame 18 will be described in detail.

[0042] Figure 3 It is Figure 2The diagram shown is a disassembled perspective view of the car's roof panel and reinforcing frame. Figure 4 It is Figure 3 The enlarged image of part B.

[0043] (Structure of the top slab)

[0044] like Figure 3 As shown, the top plate 17 is composed of a single-piece molded article. A single-piece molded article is a monolithic structure obtained by stamping a steel plate. The stamping process includes shearing to form the shape of the top plate 17, drilling to create openings in the top plate 17, and bending to bend the top plate 17. However, the drilling is not limited to stamping-based drilling; for example, drilling using a drill bit can also be applied.

[0045] The top plate 17 is a component mounted on the side plate 11. The top plate 17 is an integral structure having four mounting portions 21 (21a, 21b, 21c, 21d), four connecting portions 22 (22a, 22b, 22c, 22d), and a canopy portion 23. In the following description, the mounting portions 21a, 21b, 21c, and 21d will be collectively referred to as mounting portions 21 unless it is necessary to distinguish them. The same applies to the connecting portions 22.

[0046] The portion of the top plate 17 extending from the ceiling portion 23, through the connecting portion 22, to the mounting portion 21 is bent into a crank shape. Specifically, the ceiling portion 23 is horizontally positioned, the connecting portion 22 is bent upwards at a right angle at the outer periphery of the ceiling portion 23, and the mounting portion 21 is bent laterally at a right angle at the upper end of the connecting portion 22. Furthermore, the connecting portion 22 rises vertically from the outer edge of the ceiling portion 23, and the mounting portion 21 extends horizontally from the upper end of the connecting portion 22. A height difference D is formed between the ceiling portion 23 and the mounting portion 21 (see reference). Figure 4 It is positioned lower than the mounting part 21. The height difference D between the mounting part 21 and the canopy part 23 is equivalent to the height dimension of the connecting part 22 in the Z direction.

[0047] The four mounting portions 21 are respectively mounted on the upper ends of the corresponding side panels 11. Two of the four mounting portions 21a and 21b are arranged in pairs in the X direction, and two mounting portions 21c and 21d are arranged in pairs in the Y direction. Mounting portion 21a is mounted on the upper end of side panel 11a, and mounting portion 21b is mounted on the upper end of side panel 11b. Mounting portion 21c is mounted on the upper end of side panel 11c, and mounting portion 21d is mounted on the upper end of side panel 11d. Mounting portion 21c is located on the front side of the car 3, and mounting portion 21d is located on the rear side of the car 3. The front side of the car 3 refers to the side where the car door 12 is located in the Y direction.

[0048] Mounting section 21a has two holes h1 and h2, and mounting section 21b also has two holes h3 and h4. Mounting section 21c has four holes h5, h6, h7, and h8, and mounting section 21d has four holes h9, h10, h11, and h12. The number and position of the holes in each mounting section 21a, 21b, 21c, and 21d can be changed as needed. Mounting section 21d has an opening 25. The opening 25 is a rectangular opening that is longer in the X direction. The opening 25 is, for example, an opening for supplying air into the car compartment via a fan (not shown), i.e., an air vent. The fan is a ceiling device mounted on the top plate 17. A ventilation window (not shown) is installed in the opening 25 as needed.

[0049] The four connecting parts 22 connect the corresponding mounting parts 21 to the roof parts 23. Specifically, connecting part 22a connects the mounting part 21a to the roof parts 23, and connecting part 22b connects the mounting part 21b to the roof parts 23. Furthermore, connecting part 22c connects the mounting part 21c to the roof parts 23, and connecting part 22d connects the mounting part 21d to the roof parts 23. Two connecting parts 22a and 22b are arranged in pairs in the X direction, and two connecting parts 22c and 22d are arranged in pairs in the Y direction.

[0050] Furthermore, four connecting portions 22 are formed by bending vertically from the horizontal ceiling portion 23. In this case, two connecting portions 22a and 22b, which stand upright from one end and the other end of the ceiling portion 23 in the X direction (corresponding to the first direction), are respectively designated as first connecting portions, and two connecting portions 22c and 22d, which stand upright from one end and the other end of the ceiling portion 23 in the Y direction (corresponding to the second direction), are respectively designated as second connecting portions. In this case, to avoid interference caused by the bending of the connecting portions, a gap is formed at the joint between the first connecting portions and the second connecting portions. For example, Figure 4 As shown, a gap G is formed at the joint portion 33 between the end of the connecting portion 22b, which corresponds to the first connecting portion, and the end of the connecting portion 22c, which corresponds to the second connecting portion. In this embodiment, the gap G formed at the joint portion 33 between the connecting portions 22b and 22c is oriented towards the X direction. This is also true for the gaps formed at the joint portions between the connecting portions 22b and 22d, the joint portions between the connecting portions 22a and 22c, and the joint portions between the connecting portions 22a and 22d.

[0051] The ceiling section 23 is formed into a square flat plate when viewed from above. The top view shape of the ceiling section 23 can be rectangular or square. Lighting (not shown) is installed on the ceiling section 23. The lighting can be downlight type, LED lighting type, or other types. Furthermore, in... Figure 3 The markings for the holes formed in the ceiling section 23 for installing lighting are omitted.

[0052] (Strengthen the framework structure)

[0053] The reinforcing frame 18 is a component that reinforces the car roof 14 of the car 3. The reinforcing frame 18 is made of steel plate and has high strength (rigidity). The reinforcing frame 18 is installed at the mounting portion 21 of the roof plate 17. Furthermore, the reinforcing frame 18, together with the roof plate 17, is fixed to the upper end of the side plate 11. Figure 2 As shown, a safety barrier 19 is installed on the reinforcing frame 18. The safety barrier 19 is a component used to ensure the safety of workers when they are sitting on the car roof 14.

[0054] The reinforcing frame 18 consists of four frame components 181, 182, 183, and 184. Two frame components 181 and 182 are arranged in pairs in the X direction, and two frame components 183 and 184 are arranged in pairs in the Y direction. Frame component 183 is located at the front of the car 3, and frame component 184 is located at the rear of the car 3. Referring hereafter... Figure 3 The structure of each frame component 181, 182, 183, and 184 is described.

[0055] The frame component 181 is an integral component comprising an upper plate 181a, a lower plate 181b, and a vertical plate 181c. The upper plate 181a and the lower plate 181b are arranged opposite each other in the Z direction. The vertical plate 181c is vertically arranged in the Z direction, connecting the upper plate 181a and the lower plate 181b. The upper plate 181a has two holes h21 and h22, and the lower plate 181b has four holes h23, h24, h25, and h26. The two holes h21 and h22 are located at both ends of the frame component 181 in the longitudinal direction (Y direction). The four holes h23, h24, h25, and h26 are located in the longitudinal direction of the frame component 181 at positions further inward than the two holes h21 and h22.

[0056] The frame component 182 is an integral component comprising an upper plate 182a, a lower plate 182b, and a vertical plate 182c. The upper plate 182a and the lower plate 182b are arranged opposite each other in the Z direction. The vertical plate 182c is vertically arranged in the Z direction, connecting the upper plate 182a and the lower plate 182b. The upper plate 182a has two holes h31 and h32, and the lower plate 182b has four holes h33, h34, h35, and h36. The two holes h31 and h32 are located at both ends of the frame component 182 in the longitudinal direction (Y direction). The four holes h33, h34, h35, and h36 are located in the longitudinal direction of the frame component 182 at positions further inward than the two holes h31 and h32.

[0057] Frame component 183 is a component integrally comprising an upper plate portion 183a, a lower plate portion 183b, and a vertical plate portion 183c. The upper plate portion 183a and the lower plate portion 183b are arranged opposite each other in the Z direction. The vertical plate portion 183c is arranged vertically in the Z direction, connecting the upper plate portion 183a and the lower plate portion 183b. Cutouts 20a and 20b are formed at both ends in the longitudinal direction of frame component 183. Cutout 20a is made so that, when assembling frame components 181 and 183, the end of the lower plate portion 181b of frame component 181 will not interfere with the end of the lower plate portion 183b of frame component 183. Cutout 20b is made so that, when assembling frame components 182 and 183, the end of the lower plate portion 182b of frame component 182 will not interfere with the end of the lower plate portion 183b of frame component 183.

[0058] Two holes h41 and h42 are provided in the upper plate portion 183a, and two holes h43 and h44 are also provided in the lower plate portion 183b. The two holes h41 and h42 are located at both ends of the frame member 183 along its length (X direction). The two holes h43 and h44 are positioned in the length direction of the frame member 183 at a position that is more inward than the two holes h41 and h42.

[0059] Frame component 184 is a component integrally comprising an upper plate portion 184a, a lower plate portion 184b, and a vertical plate portion 184c. The upper plate portion 184a and the lower plate portion 184b are arranged opposite each other in the Z direction. The vertical plate portion 184c is arranged vertically in the Z direction to connect the upper plate portion 184a and the lower plate portion 184b. Cutouts 20c and 20d are formed at both ends in the longitudinal direction of frame component 184. Cutout 20c is made so that when frame components 181 and 184 are assembled, the end of the lower plate portion 181b of frame component 181 will not interfere with the end of the lower plate portion 184b of frame component 184. Cutout 20d is made so that when frame components 182 and 184 are assembled, the end of the lower plate portion 182b of frame component 182 will not interfere with the end of the lower plate portion 184b of frame component 184.

[0060] Two holes h51 and h52 are provided in the upper plate portion 184a, and two holes h53 and h54 are also provided in the lower plate portion 184b. The two holes h51 and h52 are located at both ends of the frame member 184 along its length (X direction). The two holes h53 and h54 are positioned further inward than the two holes h51 and h52 along the length of the frame member 184. The number and position of the holes provided in each frame member 181, 182, 183, and 184 can be changed as needed.

[0061] (Installation structure of the top plate and the reinforcing frame)

[0062] Next, the installation structure of the top plate 17 and the reinforcing frame 18 will be described in detail.

[0063] First, with the car roof 14 of the car 3 constructed, a reinforcing frame 18 is installed on the roof plate 17. At this time, as... Figure 5 As shown, the frame component 181 is mounted to the mounting portion 21a of the top plate 17 using rivet R1, and the frame component 182 is mounted to the mounting portion 21b of the top plate 17 using rivet R2. Figure 5 In this process, the hole h1 in the mounting portion 21a of the top plate 17 is aligned with the hole h24 in the lower plate portion 181b of the frame member 181, and the mounting portion 21a is fixed to the frame member 181 using rivets R1. Furthermore, Figure 5 In the process, the hole h3 of the mounting part 21b provided on the top plate 17 is aligned with the hole h34 of the lower plate part 182b provided on the frame member 182, and the mounting part 21b is fixed to the frame member 182 using rivets R2.

[0064] Furthermore, a receiving portion 31 is integrally formed at the upper end of the side plate 11a, and a clearance hole 31a is provided in the receiving portion 31. The receiving portion 31 is the part that receives and supports the mounting portion 21a of the top plate 17. The clearance hole 31a is a hole used to avoid interference with the rivet R1. Furthermore, a receiving portion 32 is integrally formed at the upper end of the side plate 11b, and a clearance hole 32a is provided in the receiving portion 32. The receiving portion 32 is the part that receives and supports the mounting portion 21b of the top plate 17. The clearance hole 32a is a hole used to avoid interference with the rivet R2. The car compartment 36 of the car 3 is a space surrounded on all sides (in the X and Y directions) by the side plates 11 (11a to 11d) and the car door 12, and sandwiched in the vertical direction (Z direction) by the top plate 17 and the floor (not shown). Furthermore, the inner surfaces of the side panels 11 (11a to 11d) and the inner surface of the top panel 17 become the exterior surface F facing the car compartment 36.

[0065] Furthermore, when mounting frame member 181 to mounting portion 21a of top plate 17, the number of rivets R1 used is not limited to one, and can be set as needed. The same applies when mounting frame member 182 to mounting portion 21b of top plate 17. Rivets can also be used when mounting frame member 183 to mounting portion 21c of top plate 17 and when mounting frame member 184 to mounting portion 21d of top plate 17. Moreover, the components used for mounting frame members 181, 182, 183, and 184 can be components other than rivets.

[0066] Furthermore, although not shown in the figure, both ends of frame member 183 are fixed to one end of frame members 181 and 182 by rivets, and both ends of frame member 184 are fixed to the other end of frame members 181 and 182 by rivets. In this case, one of the two holes h41 and h42 provided in the upper plate portion 183a of frame member 183 is aligned with hole h21 of frame member 181, and the two (181 and 183) are fixed by rivets. The other hole h42 is aligned with hole h31 of frame member 182, and the two (182 and 183) are fixed by rivets. Furthermore, one of the two holes h51 and h52 provided on the upper plate portion 184a of the frame member 184 is aligned with the hole h22 of the frame member 181, and the two (181, 184) are fixed with rivets, and the other hole h52 is aligned with the hole h32 of the frame member 182, and the two (182, 184) are fixed with rivets.

[0067] Next, the top plate 17 is installed onto the side plate 11. At this time, as... Figure 6As shown, the mounting portion 21a of the top plate 17 is mounted to the upper end of the side plate 11a using bolt B1 and nut N1, and the mounting portion 21b of the top plate 17 is mounted to the upper end of the side plate 11b using bolt B2 and nut N2. Figure 6 In this process, the mounting portion 21a of the top plate 17 is placed on the receiving portion 31 of the side plate 11a. Bolt B1 is inserted into the hole h25 of the frame member 181 and the hole h2 of the mounting portion 21a, so that the external thread of bolt B1 engages with nut N1. Nut N1 is a nut (such as a rivet nut) pre-fixed to the receiving portion 31. The frame member 181 is tightened by engaging the bolt B1 inserted in the holes h25 and h2 with nut N1 as described above, thereby fixing it together with the mounting portion 21a of the top plate 17 to the receiving portion 31 of the side plate 11a. Furthermore, Figure 6 In this process, the mounting portion 21b of the top plate 17 is placed on the receiving portion 32 of the side plate 11b. Bolt B2 is inserted into the hole h35 of the frame member 182 and the hole h4 of the mounting portion 21b, so that the external thread of bolt B2 engages with nut N2. Nut N2 is a nut pre-fixed to the receiving portion 32. The frame member 182 is tightened by engaging the bolt B2 inserted in the holes h35 and h4 with nut N2 as described above, thereby fixing it together with the mounting portion 21b of the top plate 17 to the receiving portion 32 of the side plate 11b.

[0068] Furthermore, the frame component 183 is fixed to the upper end of the side plate 11c together with the mounting portion 21c of the top plate 17 using bolts and nuts (not shown), and the frame component 184 is fixed to the upper end of the side plate 11d together with the mounting portion 21d of the top plate 17 using bolts and nuts (not shown).

[0069] Furthermore, among the plurality of holes h1 to h12 provided in the top plate 17 and the plurality of holes h21 to h26, h31 to h36, h41 to h44, and h51 to h54 provided in the reinforcing frame 18, it is possible to change which hole is used for mounting the reinforcing frame 18 to the top plate 17, or which hole is used for mounting the top plate 17 to the side plate 11, as needed. Moreover, the number and position of the holes provided in the top plate 17 and the reinforcing frame 18 can also be changed as needed. Furthermore, the components used for mounting the top plate 17 to the side plate 11 can be components other than bolts and nuts.

[0070] As described above, after the reinforcing frame 18 is installed on the top plate 17, the top plate 17 is installed on the side plate 11, thereby forming a suspended ceiling in the ceiling portion of the car 3. In this case, as... Figure 7As shown, the connecting portions 22 (22a, 22c) bend downward from the mounting portions 21 (21a, 21c), thereby positioning the ceiling portion 23 below the mounting portions 21 (21a, 21c) to form a suspended ceiling. Furthermore, the ceiling surface 23a of the car compartment is formed by the lower surface of the ceiling portion 23.

[0071] In this specification, "suspended ceiling" refers to a ceiling surface 23a of the top plate 17 having a predetermined height difference D (refer to) compared to the upper end of the side plate 11 surrounding the car compartment. Figure 4 and Figure 6 This is a structure positioned at a lower level. If the predetermined height difference D is too small, bending the ceiling plate 17 becomes difficult, and surveillance cameras, air vents, etc., are easily visible from the passenger's perspective. Therefore, the predetermined height difference D is preferably 20mm or more, more preferably 30mm or more, and even more preferably 40mm or more. However, if the predetermined height difference is too large, the ceiling surface 23a of the car compartment becomes lower, raising concerns about a feeling of oppression for passengers. Therefore, the predetermined height difference D is preferably 80mm or less, more preferably 70mm or less, and even more preferably 60mm or less.

[0072] Furthermore, as part of the structure of the top plate 17, the gap formed at the joint portion 33 of the connecting portion 22a and the connecting portion 22c is... Figure 4 The gaps G shown are all configured to face the X direction. Here, as... Figure 8 As shown, when the mounting portion 21a of the top plate 17 is installed on the upper end of the side plate 11a, a corner space 34 is formed between the side plate 11a and the connecting portion 22a. Furthermore, although not shown, when the mounting portion 21b of the top plate 17 is installed on the upper end of the side plate 11b, the same corner space 34 is also formed between the side plate 11b and the connecting portion 22b. In other words, the corner space 34 is a space formed by recessing the left and right sides of the ceiling portion of the car 3 upwards beyond the ceiling surface 23a. On the other hand, as... Figure 9 As shown, with the mounting portion 21c of the top plate 17 installed on the upper end of the side plate 11c, a corner space 35 larger than the aforementioned corner space 34 is formed between the side plate 11c and the connecting portion 22c. Furthermore, although not shown, with the mounting portion 21d of the top plate 17 installed on the upper end of the side plate 11d, the same corner space 35 is also formed between the side plate 11d and the connecting portion 22d. In other words, the corner space 35 is a space formed by recessing the ceiling portion of the car 3 upwards from the ceiling surface 23a on both the front and rear sides. Furthermore, the mounting portion 21d facing the corner space 35 includes the aforementioned opening 25, a hole for mounting a surveillance camera, and a ventilation hole for air exchange.

[0073] In this embodiment, the paired mounting portions 21a and 21b in the X direction correspond to the first mounting portions, and the paired mounting portions 21c and 21d in the Y direction correspond to the second mounting portions. Furthermore, as... Figure 8 As shown, the width dimension, i.e., the first width dimension, of the mounting portion 21a extending from the upper end of the connecting portion 22a along the X direction is set to W1 (mm). Furthermore, although not shown, the width dimension of the mounting portion 21b extending from the upper end of the connecting portion 22b along the X direction is also set to W1 (mm). In contrast, as... Figure 9 As shown, the width dimension of the mounting portion 21c extending from the upper end of the connecting portion 22c along the Y direction, i.e., the second width dimension, is set to W2 (mm), which is larger than W1 (mm) mentioned above. Furthermore, although not shown, the width dimension of the mounting portion 21d extending from the upper end of the connecting portion 22d along the Y direction is also set to W2 (mm). Therefore, by aligning the gap between the joint portion 33 formed between the connecting portions 22a and 22c towards the X direction, i.e., the corner space 34 side, the gap between the joint portion 33 is difficult to see from the passenger's perspective. This is also true for the gaps between the joint portions 22b and 22c, the joint portions 22a and 22d, and the joint portions 22b and 22d.

[0074] <Effects of the First Implementation Method>

[0075] The following effects are obtained from the car 3 and the elevator equipped with the car according to this embodiment.

[0076] In this embodiment, the top plate 17 is a one-piece molded product, which has a mounting portion 21 installed at the upper end of the side plate 11, a canopy portion 23 disposed at a position lower than the mounting portion 21, and a connecting portion 22 connecting the mounting portion 21 and the canopy portion 23. Therefore, components (such as joint frames) for mounting the top plate 17 to the side plate 11 are not required. Thus, the number of components required to make the ceiling portion of the car 3 a suspended ceiling can be reduced. Furthermore, with the reduction in the number of components, the assembly time of the car 3 can be reduced. Also, since the ceiling portion of the car 3 is a single-layer ceiling using the top plate 17, it is not enclosed above the top plate as in a double-layer ceiling. Therefore, the open space ensured above the top plate 17 can be used to install ceiling equipment. Therefore, the flexibility of layout when installing ceiling equipment can be increased. In addition, various specifications, such as LED lighting specifications and downlight specifications, can be accommodated for the lighting equipment installed on the top plate 17. Furthermore, in the case of a double-layered ceiling, since the space between the lower and upper ceiling panels is enclosed, the ceiling equipment needs to be installed on the upper ceiling panel. Therefore, in the case of a double-layered ceiling, the ceiling equipment protrudes upwards, and correspondingly, the height of the car ceiling increases. In contrast, in the case of a single-layered ceiling using ceiling panel 17, the ceiling equipment 37 can be installed on the mounting section 21 and the ceiling section 23, which is one level lower than it (see reference). Figure 6 Therefore, the height dimension of the car ceiling 14, including the ceiling equipment 37, can be kept smaller than that of a double-layered ceiling.

[0077] Furthermore, in this embodiment, the portion of the top plate 17 extending from the ceiling portion 23 via the connecting portion 22 to the mounting portion 21 is bent into a crank shape. This allows for a more unified appearance of the ceiling portion of the car compared to the car described in Patent Document 1. Specifically, in the car described in Patent Document 1, the lower ceiling plate (shield) is supported by a seam frame (shield fixing portion), resulting in a partially protruding structure on the outer periphery of the lower ceiling plate due to the presence of the seam frame. Furthermore, since the lower ceiling plate is made of steel and the seam frame is made of aluminum, the lower ceiling plate and the seam frame have different colors. Therefore, it is difficult to achieve a unified appearance for the car's ceiling portion. In contrast, in the car 3 of this embodiment, the portion from the ceiling portion 23 via the connecting portion 22 to the mounting portion 21 is formed by a single-piece top plate 17. Therefore, it does not result in a partially protruding structure on the outer periphery of the ceiling portion 23, and the entire ceiling surface 23a becomes a flat surface without any unevenness. Furthermore, it allows the ceiling of car 3 to be uniformly colored. Therefore, it gives the ceiling of car 3 a sense of unity.

[0078] Furthermore, in this embodiment, a reinforcing frame 18 is installed on the mounting portion 21 of the top plate 17. This suppresses the phenomenon of the top plate 17 returning to its original shape after bending, i.e., springback.

[0079] Furthermore, in this embodiment, the reinforcing frame 18 is fixed together with the mounting portion 21 of the top plate 17 to the upper end of the side plate 11. As a result, the car roof 14 of the car 3 can have high strength.

[0080] Furthermore, in this embodiment, a safety barrier 19 is installed on the reinforcing frame 18. Therefore, the high strength of the reinforcing frame 18 allows for the secure installation of the safety barrier 19.

[0081] Furthermore, in this embodiment, the gap G formed by the joint portion 33 between the first connecting portion (22a, 22b) and the second connecting portion (22c, 22d) is arranged facing the X direction. Therefore, the gap G of the joint portion 33 is difficult to see from the passenger's perspective. This results in a good appearance for the ceiling of the car 3.

[0082] <Second Implementation Method>

[0083] The elevator car 3 of the second embodiment differs from the first embodiment in the structure of the top plate 17. Specifically, in the first embodiment, the top plate 17 is formed by a single molded piece, but in the second embodiment, as shown... Figure 10 As shown, the top plate 170 is composed of three integrally molded parts. The structure of the top plate 170 will be described in detail below.

[0084] The top plate 170 is composed of a first top plate 171, a second top plate 172, and a third top plate 173. Each of the three top plates is integrally molded. Furthermore, the first top plate 171, the second top plate 172, and the third top plate 173 are arranged in the X direction. Specifically, when viewed from the first top plate 171, the second top plate 172 is positioned on one side of the X direction, and the third top plate 173 is positioned on the other side. That is, the first top plate 171 is positioned between the second top plate 172 and the third top plate 173 in the X direction.

[0085] The first top plate 171 is an integral structure having a canopy portion 190a, two mounting portions 191a and 191b, two connecting portions 192a and 192b, and two connecting portions 193a and 193b. The mounting portions 191a and 191b correspond to the second mounting portions, and the connecting portions 192a and 192b correspond to the second connecting portions. An opening 194 for air supply is provided in the mounting portion 191b. The two connecting portions 193a and 193b are each bent into an inverted L-shape. Furthermore, the mounting portion 191a has two holes h101 and h102, and the mounting portion 191b has two holes h103 and h104. The connecting portion 193a has four connecting holes h105, and the connecting portion 193b has four connecting holes h106.

[0086] The second top plate 172 is an integral structure comprising a canopy portion 190b, three mounting portions 195a, 195b, and 195c, three connecting portions 196a, 196b, and 196c, and a connecting portion 197. The connecting portion 197 is bent into an inverted L-shape. Mounting portions 195a and 195b correspond to the second mounting portions, and mounting portion 195c corresponds to the first mounting portion. Similarly, connecting portions 196a and 196b correspond to the second connecting portions, and connecting portion 196c corresponds to the first connecting portion. Mounting portion 195a has two holes h107 and h108, mounting portion 195b has two holes h109 and h110, and mounting portion 195c has two holes h111 and h112. The connecting portion 197 has four connecting holes h115.

[0087] The third top plate 173 is an integral structure comprising a canopy portion 190c, three mounting portions 197a, 197b, 197c, three connecting portions 198a, 198b, 198c, and a connecting portion 199. The connecting portion 199 is bent into an inverted L-shape. Mounting portions 197a and 197b correspond to the second mounting portions, and mounting portion 197c corresponds to the first mounting portion. Connecting portions 198a and 198b correspond to the second connecting portions, and connecting portion 198c corresponds to the first connecting portion. Mounting portion 197a has two holes h116 and h117, mounting portion 197b has two holes h118 and h119, and mounting portion 197c has two holes h120 and h121. Connecting portion 199 has four connecting holes h122.

[0088] In the top plate 170 constructed with the above structure, the first top plate 171, the second top plate 172, and the third top plate 173 are connected to each other in the X direction, thereby forming a single ceiling surface from the three ceiling portions 190a, 190b, and 190c. At this time, regarding the first top plate 171 and the second top plate 172, the connecting portion 197 covers the connecting portion 193a, so that the connecting portions 197 and 193a are close to each other. In this state, bolts are passed through the connecting holes h105 and h115, and nuts are used to fasten the connecting portions 197 and 193a. Alternatively, rivets are passed through the connecting holes h105 and h115 and riveted. Furthermore, regarding the first top plate 171 and the third top plate 173, the connecting portion 193b is covered over the connecting portion 199, so that the connecting portions 199 and 193b are close to each other. In this state, bolts are passed through the connecting holes h106 and h122 and nuts are used to tighten the connecting portions 199 and 193b. Alternatively, rivets are passed through the connecting holes h106 and h122 and riveted. Thus, the first top plate 171, the second top plate 172, and the third top plate 173 can be connected in the X direction.

[0089] Even when the top plate 170 is composed of three integrally molded parts (first top plate 171, second top plate 172 and third top plate 173), the same effect as the first embodiment described above can be obtained.

[0090] Furthermore, the holes h101-h104, h107-h112, and h116-h121 provided in the mounting portions 191a, 191b, 195a, 195b, 195c, 197a, 197b, and 197c are used to mount the reinforcing frame (not shown) to the top plate 170, or to mount the top plate 170 to the side plate (not shown). In this case, the same reinforcing frame 18 as described in the first embodiment can be used.

[0091] <Variations, etc.>

[0092] The scope of the present invention is not limited to the above-described embodiments, but also includes various modifications and improvements made within the scope that can derive the specific effects obtained by the constituent elements of the invention and their combination.

[0093] For example, in the first embodiment described above, the top plate 17 is composed of one integrally molded article, and in the second embodiment described above, the top plate 170 is composed of three integrally molded articles. However, the number of integrally molded articles constituting the top plate can be two or more.
