Description

[Technical field]

[0001] The present invention relates to an elevator and a car. [Background technology]

[0002] For example, surveillance cameras are sometimes installed in elevator cars for crime prevention purposes. The surveillance cameras are installed on the ceiling of the car to capture the entire interior of the car. When a surveillance camera is installed on the ceiling of the car, if it is placed in a location that is easily visible to passengers in the car, the design will be compromised.

[0003] To address this issue, elevator cars are known that employ a so-called dropped ceiling, in which the ceiling surface of the elevator car that is visible to passengers is positioned lower than the upper end of the side panels of the elevator car (see, for example, Patent Document 1). When an elevator car has a dropped ceiling, a space (hereinafter also referred to as a "corner space") that is recessed above the ceiling surface can be secured inside the side panels and around the ceiling surface. For this reason, by placing a surveillance camera in the corner space, it becomes difficult for passengers to see the surveillance camera. This can improve the design of the elevator car.

[0004] Drop ceilings are not only used to make it harder for passengers to see surveillance cameras, but may also be used for various other reasons, such as making it harder for passengers to see air outlets and vents in the ceiling of the car. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] International Publication No. 2018 / 230161 Summary of the Invention [Problem to be solved by the invention]

[0006] However, in the past, in order to make the ceiling of the car a dropped ceiling, at least two members (brackets, joint frames, etc.) are attached to the upper ends of the side panels, and a top panel consisting of a shielding plate or the like is supported by the above two members. Also, in the past, a so-called double ceiling was formed in which a lower top panel consisting of a shielding plate or the like was placed below the upper top panel, and further, in order to secure a desired space between the upper and lower top panels, a spacer member was placed and fixed on the upper ends of the side panels, and the upper top panel was attached on top of this spacer member. For this reason, in the past, there was a drawback in that a large number of parts were required to construct the ceiling of the car.

[0007] The present invention has been made to solve the above-mentioned problems, and its object is to provide an elevator and a car that can reduce the number of parts required to make the ceiling part of the car a dropped ceiling. [Means for solving the problem]

[0008] The passenger car according to the present invention comprises side panels surrounding a car chamber and a top panel attached to the side panels, the top panel being formed as an integrally molded product having an attachment portion attached to the upper end of the side panels, a ceiling portion disposed at a lower position than the attachment portion with a step provided between the attachment portion and the top panel, and a connection portion connecting the attachment portion and the ceiling portion. An opening is provided in the portion of the attachment portion that contacts the car chamber. The elevator according to the present invention is configured to include the above passenger car. Effect of the Invention

[0009] According to the present invention, the number of parts required to make the ceiling portion of a car into a dropped ceiling can be reduced. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. In this specification and the drawings, elements having substantially the same functions or configurations are denoted by the same reference numerals, and duplicated explanations will be omitted.

[0012] First Embodiment FIG. 1 is a schematic diagram showing a configuration example of an elevator according to a first embodiment. As shown in FIG. 1, an elevator is installed in the hoistway of an architectural structure such as a building, and is equipped with a hoist 1, a main rope 2, a car 3, a pair of under-car pulleys 4A, 4B, a counterweight 5, and a pulley 6.

[0013] The hoist 1 is a device that winds up the main rope 2 to raise and lower the car 3. The hoist 1 is installed at the top of the elevator. One end and the other end of the main rope 2 are fixed to the top of the elevator. The main rope 2 is wound around a pair of under-car pulleys 4A and 4B, the hoist 1, and a pulley 6. The car 3 ascends and descends in the elevator while being guided by a guide rail (not shown). The pair of under-car pulleys 4A and 4B are disposed below the car 3. The counterweight 5 is a weight for balancing the mass with the car 3. When the main rope 2 is wound up by the hoist 1, the counterweight 5 ascends and descends in the opposite direction to the car 3. The pulley 6 ascends and descends together with the counterweight 5. The configuration of the elevator is not limited to the configuration shown in FIG. 1, and various configurations can be adopted.

[0014] FIG. 2 is a schematic perspective view showing the configuration of the car according to the first embodiment. In this embodiment, in order to clarify the positional relationship of each part of the car 3, the left-right direction of the car 3 as viewed from the elevator hall side is defined as the X direction, the depth direction of the car 3 is defined as the Y direction, and the height direction of the car 3 is defined as the Z direction. In the elevator shaft in which the car 3 is arranged, the X direction and the Y direction are parallel to the horizontal direction, and the Z direction is parallel to the vertical direction.

[0015] The car 3 has a car compartment (not shown) that is a space for accommodating passengers and baggage. The car 3 includes 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.

[0016] The four side plates 11 are arranged to surround the car chamber. Of the four side plates 11, two side plates 11a and 11b are arranged in a pair on the left and right sides of the car 3. Side plate 11c is arranged at the front of the car 3, and side plate 11d is arranged at the rear of the car 3. In the following description, when it is not necessary to distinguish between the individual side plates 11a, 11b, 11c, and 11d, they will be collectively referred to as side plates 11.

[0017] A car door 12 is disposed at the front of the car 3. The car door 12 is a door that opens and closes an entrance leading to a car chamber of the car 3. The side plate 11c is disposed above the car door 12 at the front of the car 3. A sill 16 is attached to the front of the car 3 at a position below the car door 12. A guide groove 16a is formed in the sill 16. The car door 12 moves to open and close in the X direction while being guided by the guide groove 16a of the sill 16.

[0018] The car floor 13 is disposed under the passenger car 3. Although not shown, the car floor 13 includes a floor panel on which passengers and baggage are placed, and a support mechanism for supporting the floor panel.

[0019] The car ceiling 14 includes a top plate 17 and a reinforcing frame 18. The top plate 17 and the reinforcing frame 18 will be described in detail later.

[0020] The cage frame 15 is composed of two vertical frames 15a and 15b, an upper frame 15c, and a lower frame (not shown). The cage frame 15 is arranged in a vertically long rectangle when the cage 3 is viewed from the direction A. The two vertical frames 15a and 15b are arranged in pairs on the left and right sides of the cage 3. The upper frame 15c is disposed at the upper portion of the car 3 in a state where the upper ends of the two vertical frames 15a, 15b are connected to each other. The lower frame is disposed at the lower portion (bottom) of the car 3 in a state where the lower ends of the two vertical frames 15a, 15b are connected to each other.

[0021] Next, the configurations of the top plate 17 and the reinforcing frame 18 will be described in detail. 3 is an exploded perspective view of a top plate and a reinforcing frame included in the car shown in FIG. 2, and FIG. 4 is an enlarged view of a portion B in FIG.

[0022] (Top plate configuration) As shown in Fig. 3, the top plate 17 is configured as a single integrally molded product. The integrally molded product is an integral structure obtained by pressing a steel plate. The pressing process includes a shearing process for forming the outer shape of the top plate 17, a punching process for making holes in the top plate 17, and a bending process for bending the top plate 17. However, the punching process is not limited to punching by pressing, and it is also possible to apply punching using a drill, for example.

[0023] The top plate 17 is a member attached to the side plate 11 described above. The top plate 17 is an integral structure having four mounting portions 21 (21a, 21b, 21c, 21d), four connection portions 22 (22a, 22b, 22c, 22d), and one ceiling portion 23. In the following description, when there is no need to distinguish between the individual mounting portions 21a, 21b, 21c, 21d, they will be collectively referred to as mounting portions 21. The same applies to the connection portions 22.

[0024] The top plate 17 is bent in a crank shape from the ceiling portion 23 through the connection portion 22 to the mounting portion 21. Specifically, the ceiling portion 23 is disposed horizontally, the connection portion 22 is bent upward at a right angle at the outer periphery of the ceiling portion 23, and the mounting portion 21 is bent horizontally at a right angle at the upper end portion of the connection portion 22. The connection portion 22 stands vertically from the outer edge of the ceiling portion 23, and the mounting portion 21 extends horizontally from the upper end portion of the connection portion 22. The ceiling portion 23 is disposed at a lower position than the mounting portion 21 with a step D (see FIG. 4) between the ceiling portion 23 and the mounting portion 21. The step D between the mounting portion 21 and the ceiling portion 23 corresponds to the height dimension of the connection portion 22 in the Z direction.

[0025] The four mounting parts 21 are parts that are attached to the upper ends of the corresponding side plates 11. Of the four mounting parts 21, two mounting parts 21a and 21b are arranged in a pair in the X direction, and two mounting parts 21c and 21d are arranged in a pair in the Y direction. The mounting part 21a is attached to the upper end of the side plate 11a, and the mounting part 21b is attached to the upper end of the side plate 11b. The mounting part 21c is attached to the upper end of the side plate 11c, and the mounting part 21d is attached to the upper end of the side plate 11d. The mounting part 21c is arranged on the front side of the car 3, and the mounting part 21d is arranged on the rear side of the car 3. The front side of the car 3 refers to the side on which the car door 12 is arranged in the Y direction.

[0026] The mounting portion 21a has two holes h1 and h2, and the mounting portion 21b has two holes h3 and h4. The mounting portion 21c has four holes h5, h6, h7, and h8, and the mounting portion 21d has four holes h9, h10, h11, and h12. The number and positions of the holes provided in each of the mounting portions 21a, 21b, 21c, and 21d can be changed as needed. The mounting portion 21d has an opening 25. The opening 25 is a rectangular opening that is long in the X direction. The opening 25 corresponds to an opening for sending air into the car by driving a fan (not shown), that is, an air outlet. The fan is a ceiling device mounted on the top plate 17. A louver (not shown) is attached to the opening 25 as needed.

[0027] The four connection parts 22 are parts that connect the corresponding mounting parts 21 and the ceiling part 23. Specifically, the connection part 22a connects the mounting part 21a and the ceiling part 23, and the connection part 22b connects the mounting part 21b and the ceiling part 23. The connection part 22c connects the mounting part 21c and the ceiling part 23, and the connection part 22d connects the mounting part 21d and the ceiling part 23. Of the four connection parts 22, two connection parts 22a and 22b are arranged in a pair in the X direction, and two connection parts 22c and 22d are arranged in a pair in the Y direction.

[0028] The four connection portions 22 are formed by bending vertically from the horizontal ceiling portion 23. In this case, the two connection parts 22a and 22b rising from one end and the other end of the ceiling part 23 in the X direction corresponding to the first direction are respectively defined as first connection parts, and the two connection parts 22c and 22d rising from one end and the other end of the ceiling part 23 in the Y direction corresponding to the second direction are respectively defined as second connection parts. In this case, a gap is formed at the joint between the first connection part and the second connection part to avoid interference caused by bending the connection parts. As a specific example, as shown in FIG. 4, a gap G is formed at the joint 33 between the end of the connection part 22b corresponding to the first connection part and the end of the connection part 22c corresponding to the second connection part. In this embodiment, the gap G formed at the joint 33 between the connection part 22b and the connection part 22c is arranged facing the X direction. The same applies to the gap formed at the joint between connection portion 22b and connection portion 22d, the gap formed at the joint between connection portion 22a and connection portion 22c, and further to the gap formed at the joint between connection portion 22a and connection portion 22d.

[0029] The ceiling portion 23 is formed in a flat plate shape that is quadrangular in plan view. The shape of the ceiling portion 23 in plan view may be rectangular or square. Lighting (not shown) is attached to the ceiling portion 23. The lighting may be a downlight, an LED lighting, or other specifications. Note that in FIG. 3, the hole formed in the ceiling portion 23 for attaching the lighting is omitted.

[0030] (Structure of the reinforcing frame) The reinforcing frame 18 is a member that reinforces the car ceiling 14 of the car 3. The reinforcing frame 18 is made of steel plate and has high strength (rigidity). The reinforcing frame 18 is attached to mounting portions 21 of the top plate 17. The reinforcing frame 18 is also fixed to the upper ends of the side plates 11 together with the top plate 17. As shown in FIG. 2, a safety fence 19 is attached to the reinforcing frame 18. The safety fence 19 is a member that ensures safety when an operator works on the car ceiling 14.

[0031] The reinforcing frame 18 is composed of four frame members 181, 182, 183, and 184. Of these, the two frame members 181 and 182 are arranged in a pair in the X direction, and the two frame members 183 and 184 are arranged in a pair in the Y direction. In addition, the frame member 183 is arranged on the front side of the car 3, and the frame member 184 is arranged on the rear side of the car 3.

[0038] (Top plate and reinforcing frame attachment structure) Next, the mounting structure of the top plate 17 and the reinforcing frame 18 will be described in detail. First, when constructing the car ceiling 14 of the passenger car 3, the reinforcing frame 18 is attached to the top plate 17. At that time, as shown in Fig. 5, a frame member 181 is attached to the mounting portion 21a of the top plate 17 by a rivet R1, and a frame member 182 is attached to the mounting portion 21b of the top plate 17 by a rivet R2. In Fig. 5, a hole h1 provided in the mounting portion 21a of the top plate 17 and a hole h24 provided in the lower plate portion 181b of the frame member 181 are aligned, and the mounting portion 21a and the frame member 181 are fixed by the rivet R1. Also, in Fig. 5, a hole h3 provided in the mounting portion 21b of the top plate 17 and a hole h34 provided in the lower plate portion 182b of the frame member 182 are aligned, and the mounting portion 21b and the frame member 182 are fixed by the rivet R2.

[0039] A receiving portion 31 is integrally formed at the upper end of the side plate 11a, and an escape hole 31a is provided in the receiving portion 31. The receiving portion 31 is a portion that receives and supports the mounting portion 21a of the top plate 17. The escape hole 31a is a hole for avoiding interference with the rivet R1. A receiving portion 32 is integrally formed at the upper end of the side plate 11b, and an escape hole 32a is provided in the receiving portion 32. The receiving portion 32 is a portion that receives and supports the mounting portion 21b of the top plate 17. The escape hole 32a is a hole for avoiding interference with the rivet R2. The car chamber 36 of the car 3 is surrounded on all four sides (X direction and Y direction) by the side plates 11 (11a to 11d) and the car door 12, and is a space sandwiched between the top plate 17 and the floor plate (not shown) in the vertical direction (Z direction). The inner surfaces of the side plates 11 (11a to 11d) and the inner surface of the top plate 17 form a design surface F facing the cab chamber .

[0040] When attaching frame member 181 to attachment portion 21a of tabletop 17, the number of rivets R1 used is not limited to one and may be set as necessary. This also applies to the case of attaching frame member 182 to attachment portion 21b of tabletop 17. Rivets may also be used when attaching frame member 183 to attachment portion 21c of tabletop 17 and when attaching frame member 184 to attachment portion 21d of tabletop 17. Components used to attach frame members 181, 182, 183, 184 may be components other than rivets.

[0041] Although not shown, both ends of the frame member 183 are fixed to one ends of the frame members 181 and 182 by rivets, and both ends of the frame member 184 are fixed to the other ends of the frame members 181 and 182 by rivets. In this case, of two holes h41 and h42 provided in the upper plate portion 183a of the frame member 183, one hole h41 is aligned with the hole h21 of the frame member 181 to fix both (181, 183) with the rivet, and the other hole h42 is aligned with the hole h31 of the frame member 182 to fix both (182, 183) with the rivet. Furthermore, of the two holes h51, h52 provided in the upper plate portion 184a of the frame member 184, one hole h51 is aligned with the hole h22 of the frame member 181 and both (181, 184) are fixed together with a rivet, and the other hole h52 is aligned with the hole h32 of the frame member 182 and both (182, 184) are fixed together with a rivet.

[0042] Next, the top plate 17 is attached to the side plate 11. At this time, as shown in FIG. 6, the mounting portion 21a of the top plate 17 is attached to the upper end of the side plate 11a by a bolt B1 and a nut N1, and the mounting portion 21b of the top plate 17 is attached to the upper end of the side plate 11b by a bolt B2 and a nut N2. In FIG. 6, the mounting portion 21a of the top plate 17 is placed on the receiving portion 31 of the side plate 11a, and the bolt B1 is inserted into the hole h25 of the frame member 181 and the hole h2 of the mounting portion 21a, and the male thread portion of the bolt B1 is engaged with the nut N1. The nut N1 is a nut (such as a pop nut) that is fixed to the receiving portion 31 in advance. The frame member 181 is fixed to the receiving portion 31 of the side plate 11a together with the mounting portion 21a of the top plate 17 by engaging the bolt B1 inserted into the holes h25 and h2 as described above with the nut N1 and tightening it. 6, the mounting portion 21b of the top plate 17 is placed on the receiving portion 32 of the side plate 11b, and the bolt B2 is inserted into the hole h35 of the frame member 182 and the hole h4 of the mounting portion 21b, and the male thread portion of the bolt B2 is engaged with the nut N2. The nut N2 is a nut that is fixed to the receiving portion 32 in advance. The frame member 182 is fixed to the receiving portion 32 of the side plate 11b together with the mounting portion 21b of the top plate 17 by engaging the bolt B2 inserted into the holes h35 and h4 as described above with the nut N2 and tightening it.

[0043] In addition, frame member 183 is fixed to the upper end of side plate 11c together with mounting portion 21c of top plate 17 by bolts and nuts not shown, and frame member 184 is fixed to the upper end of side plate 11d together with mounting portion 21d of top plate 17 by bolts and nuts not shown.

[0044] It should be noted that which of the multiple holes h1 to h12 provided in the top plate 17 and the multiple holes h21 to h26, h31 to h36, h41 to 44, and h51 to h54 provided in the reinforcing frame 18 is used to attach the top plate 17 to the reinforcing frame 18, or which of the holes is used to attach the top plate 17 to the side plate 11, can be changed as necessary. In addition, the number and positions of the holes provided in the top plate 17 and the reinforcing frame 18 can also be changed as necessary. In addition, the parts used to attach the top plate 17 to the side plate 11 may be parts other than bolts and nuts.

[0045] As described above, after the reinforcing frame 18 is attached to the top plate 17, the top plate 17 is attached to the side plate 11 to form a dropped ceiling in the ceiling portion of the car 3. In this case, the dropped ceiling is formed by bending the connection parts 22 (22a, 22c) from the mounting parts 21 (21a, 21c) and protruding downward, as shown in Fig. 7, so that the ceiling part 23 is positioned lower than the mounting parts 21 (21a, 21c). Also, the ceiling surface 23a of the car room is formed by the underside of the ceiling part 23.

[0046] In this specification, a dropped ceiling refers to a structure in which the ceiling surface 23a of the top plate 17 is disposed at a position one step lower than the upper end of the side plate 11 surrounding the car, with a predetermined step D (see Figs. 4 and 6). If the predetermined step D is too small, bending of the top plate 17 becomes difficult, and the surveillance camera, the air outlet, and the like become easily visible to passengers. For this reason, the predetermined step D is preferably 20 mm or more, more preferably 30 mm or more, and even more preferably 40 mm or more. However, if the predetermined step is too large, the ceiling surface 23a of the car may be lowered accordingly, which may cause a feeling of oppression to passengers. For this reason, the predetermined step D is preferably 80 mm or less, more preferably 70 mm or less, and even more preferably 60 mm or less.

[0047] In addition, as a configuration of the top plate 17, the gap formed at the joint 33 between the connection portion 22a and the connection portion 22c is arranged facing the X direction, similar to the gap G shown in FIG. 4. Here, as shown in FIG. 8, when the mounting portion 21a of the top plate 17 is attached to the upper end of the side plate 11a, a corner space 34 is formed between the side plate 11a and the connection portion 22a. Although not shown, when the mounting portion 21b of the top plate 17 is attached to the side plate 11b, a corner space 34 similar to the above is also formed between the side plate 11b and the connection portion 22b. That is, the corner space 34 is a space formed on the left and right sides of the ceiling portion of the car 3, recessed above the ceiling surface 23a. On the other hand, as shown in FIG. 9, when the mounting portion 21c of the top plate 17 is attached to the upper end of the side plate 11c, a corner space 35 larger than the above corner space 34 is formed between the side plate 11c and the connection portion 22c. Although not shown, when the mounting portion 21d of the top plate 17 is attached to the upper end of the side plate 11d, a corner space 35 similar to the above is also formed between the side plate 11d and the connection portion 22d. That is, the corner space 35 is a space formed on the front and rear sides of the ceiling part of the car 3, recessed above the ceiling surface 23a. The mounting portion 21d facing the corner space 35 is also formed with the above-mentioned opening 25, a hole for mounting a surveillance camera, and a vent hole for ventilation.

[0048] In this embodiment, the mounting parts 21a and 21b that are paired in the X direction correspond to the first mounting parts, and the mounting parts 21c and 21d that are paired in the Y direction correspond to the second mounting parts. As shown in FIG. 8, the width dimension of the mounting part 21a extending in the X direction from the upper end of the connection part 22a, i.e., the first width dimension, is set to W1 (mm). Although not shown, the width dimension of the mounting part 21b extending in the X direction from the upper end of the connection part 22b is also set to W1 (mm). On the other hand, as shown in FIG. 9, the width dimension of the mounting part 21c extending in the Y direction from the upper end of the connection part 22c, i.e., the second width dimension, is set to W2 (mm) larger than the above W1 (mm). Although not shown, the width dimension of the mounting part 21d extending in the Y direction from the upper end of the connection part 22d is also set to W2 (mm). For this reason, by arranging the gap formed at seam 33 between connecting portion 22a and connecting portion 22c in the X direction, i.e., toward corner space 34, the gap at seam 33 becomes less visible to passengers. This also applies to the gap formed at seam 33 between connecting portion 22b and connecting portion 22c, the gap formed at seam 33 between connecting portion 22a and connecting portion 22d, and further the gap formed at seam 33 between connecting portion 22b and connecting portion 22d.

[0049] <Advantages of the First Embodiment> The car 3 according to this embodiment and the elevator equipped with the car 3 provide the following advantages.

[0050] In this embodiment, the top plate 17 is configured as an integrally molded product having an attachment portion 21 attached to the upper end of the side plate 11, a ceiling portion 23 disposed at a position lower than the attachment portion 21, and a connection portion 22 connecting the attachment portion 21 and the ceiling portion 23. This eliminates the need for parts (such as joint frames) for attaching the top plate 17 to the side plate 11. This reduces the number of parts required to make the ceiling portion of the car 3 a dropped ceiling. In addition, the reduction in the number of parts reduces the assembly labor of the car 3. In addition, since the ceiling portion of the car 3 is a single ceiling using the top plate 17, the top of the top plate is not closed as in the case of a double ceiling. Therefore, it is possible to install ceiling equipment by utilizing the open space secured above the top plate 17. Therefore, it is possible to increase the degree of freedom of layout when installing ceiling equipment. In addition, it is possible to accommodate various specifications, such as LED lighting specifications and downlight specifications, for the lighting equipment attached to the top plate 17. Furthermore, in the case of a double ceiling, the space between the lower top plate and the upper top plate is closed, so the ceiling equipment needs to be installed on the upper top plate. For this reason, in the case of a double ceiling, the height dimension of the car ceiling is larger by the amount that the ceiling equipment protrudes upward. In contrast, in the case of a single ceiling using top plate 17, the ceiling equipment 37 (see Figure 6) can be installed on the mounting part 21 or the ceiling part 23, which is one step lower than that. For this reason, the height dimension of the car ceiling 14, including the ceiling equipment 37, can be kept smaller than in the case of a double ceiling.

[0051] In addition, in this embodiment, the top plate 17 is bent in a crank shape from the ceiling portion 23 through the connection portion 22 to the attachment portion 21. This allows a sense of unity to be created in 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 top plate (shielding plate) is supported by a joint frame (shielding plate fixing portion), so the outer periphery of the lower top plate is partially protruding due to the presence of the joint frame. In addition, since the lower top plate is made of a steel plate and the joint frame is made of aluminum, the lower top plate and the joint frame have different colors. For this reason, it is difficult to create a sense of unity in the ceiling portion of the car. In contrast, in the car 3 according to this embodiment, the ceiling portion 23 through the connection portion 22 to the attachment portion 21 is formed by the top plate 17, which is an integrally molded product. For this reason, the outer periphery of the ceiling portion 23 does not partially protrude, and the entire ceiling surface 23a is a flat surface without unevenness. In addition, the entire ceiling of the car 3 can be unified in the same color. This allows the ceiling of car 3 to have a sense of unity.

[0052] In addition, in this embodiment, a configuration is adopted in which a reinforcing frame 18 is attached to the mounting portion 21 of the top plate 17. This makes it possible to suppress springback, a phenomenon in which the top plate 17 tries to return to its original shape after bending.

[0053] In this embodiment, the reinforcing frame 18 is fixed to the upper end of the side plate 11 together with the mounting portion 21 of the top plate 17. This allows the car ceiling 14 of the car 3 to have high strength.

[0054] In this embodiment, a safety fence 19 is attached to the reinforcing frame 18. This allows the high strength of the reinforcing frame 18 to be utilized to firmly install the safety fence 19.

[0055] In this embodiment, the gap G formed at the joint 33 between the first connection parts (22a, 22b) and the second connection parts (22c, 22d) is arranged to face the X direction. This makes the gap G at the joint 33 less visible to passengers. This improves the appearance of the ceiling of the car 3.

[0056] <Second embodiment> The car 3 according to the second embodiment is different from the first embodiment in the configuration of the top plate 17. Specifically, in the first embodiment, the top plate 17 is formed by one integrally molded product, but in the second embodiment, as shown in Fig. 10, the top plate 170 is formed by three integrally molded products. The configuration of the top plate 170 will be described in detail below.

[0057] The top plate 170 is composed of a first top plate 171, a second top plate 172, and a third top plate 173. The first top plate 171, the second top plate 172, and the third top plate 173 are each composed of an integrally molded product. The first top plate 171, the second top plate 172, and the third top plate 173 are arranged side by side in the X direction. Specifically, the second top plate 172 is arranged on one side in the X direction as viewed from the first top plate 171, and the third top plate 173 is arranged on the other side in the X direction. That is, the first top plate 171 is arranged between the second top plate 172 and the third top plate 173 in the X direction.

[0058] The first top plate 171 is an integral structure having a ceiling portion 190a, two mounting portions 191a and 191b, two connecting portions 192a and 192b, and two linking portions 193a and 193b. The mounting portions 191a and 191b correspond to the second mounting portion, and the linking portions 192a and 192b correspond to the second linking portion. The mounting portion 191b is provided with an opening 194 for blowing air. The two linking portions 193a and 193b are each bent into an inverted L-shape. The mounting portion 191a is provided with two holes h101 and h102, and the mounting portion 191b is provided with two holes h103 and h104. The linking portion 193a is provided with four linking holes h105, and the linking portion 193b is provided with four linking holes h106.

[0059] The second top plate 172 is an integral structure having a ceiling portion 190b, three mounting portions 195a, 195b, and 195c, three connecting portions 196a, 196b, and 196c, and one connecting portion 197. The connecting portion 197 is bent into an inverted L shape. The mounting portions 195a and 195b correspond to the second mounting portion, and the mounting portion 195c corresponds to the first mounting portion. The connecting portions 196a and 196b correspond to the second connecting portion, and the connecting portion 196c corresponds to the first connecting portion. The mounting portion 195a has two holes h107 and h108, the mounting portion 195b has two holes h109 and h110, and the mounting portion 195c has two holes h111 and h112. The connecting portion 197 has four connecting holes h115.

[0060] The third top panel 173 is an integral structure having a ceiling portion 190c, three mounting portions 197a, 197b, 197c, three connecting portions 198a, 198b, 198c, and one connecting portion 199. The connecting portion 199 is bent into an inverted L shape. The mounting portions 197a, 197b correspond to the second mounting portion, and the mounting portion 197c corresponds to the first mounting portion. The connecting portions 198a, 198b correspond to the second connecting portion, and the connecting portion 198c corresponds to the first connecting portion. The mounting portion 197a has two holes h116, h117, the mounting portion 197b has two holes h118, h119, and the mounting portion 197c has two holes h120, h121. The connecting portion 199 has four connecting holes h122.

[0061] In the top plate 170 having the above-mentioned configuration, the first top plate 171, the second top plate 172, and the third top plate 173 are mutually connected in the X direction, so that the three ceiling parts 190a, 190b, and 190c substantially form one ceiling surface. In this case, for the first top plate 171 and the second top plate 172, the connecting part 193a is placed over the connecting part 197, and the connecting parts 197 and 193a are brought into close contact or close to each other, and in this state, the connecting parts 197 and 193a are fastened by nuts after passing bolts through the respective connecting holes h105 and h115. Alternatively, rivets are passed through the respective connecting holes h105 and h115 and crimped. For the first top plate 171 and the third top plate 173, the connecting portion 193b is placed over the connecting portion 199, and the connecting portions 199, 193b are brought into close contact with or close to each other, and in this state, bolts are passed through the respective connecting holes h106, h122 and the connecting portions 199, 193b are fastened with nuts. Alternatively, rivets are passed through the respective connecting holes h106, h122 and fastened. This allows the first top plate 171, the second top plate 172, and the third top plate 173 to be connected in the X direction.

[0062] Even when the top plate 170 is configured from three integrally molded parts (the first top plate 171, the second top plate 172, and the third top plate 173) in this manner, the same effects as those of the first embodiment can be obtained.

[0063] The holes h101-h104, h107-h112, h116-h121 provided in the mounting portions 191a, 191b, 195a, 195b, 195c, 197a, 197b, 197c are used to attach a reinforcing frame (not shown) to the top plate 170 and to attach the top plate 170 to side plates (not shown). In this case, the reinforcing frame 18 similar to that of the first embodiment can be used as the reinforcing frame.

[0064] <Modifications, etc.> The technical scope of the present invention is not limited to the above-described embodiments, but also includes forms in which various modifications and improvements are made within the scope that can derive specific effects obtained by the constituent elements of the invention and their combinations.

[0065] For example, in the first embodiment described above, the top plate 17 is formed from one integrally molded product, and in the second embodiment described above, the top plate 170 is formed from three integrally molded products, but the number of integrally molded products that make up the top plate may be two or four or more.
