Description

Elevator car and method for assembling the car

[0001] The present invention relates to an elevator car and a method for assembling the car.

[0002] A technique for assembling the side panels that make up an elevator car from inside the car is disclosed in Patent Document 1 below. Patent Document 1 describes the process as including "the steps of placing the last side panel on a support part of an assembly tool and moving it near the space between two side panel blocks, fitting the side panel into the space and temporarily holding it at the midpoint in the height direction of the side panel blocks, forming a gap between the bottom of the side panel and the floor, pulling the support part of the assembly tool out of the gap, lowering the side panel from the midpoint to the floor, and connecting the bottom of the side panel to the floor," and also states that both ends of the bottom of the last side panel are fixed to the top of the floor with fasteners such as bolts.

[0003] Japanese Patent Application Laid-Open No. 2016-132555

[0004] However, when fastening the last side panel from inside the car, it is not possible to reach around or see the outside from inside the car, so securing the last side panel using fasteners such as bolts requires considerable experience and skill.

[0005] Therefore, an object of the present invention is to provide an elevator car and a method for assembling the car that allow components to be fixed together without the need for fasteners such as bolts.

[0006] In order to solve the above problem, for example, the configuration described in the claims is adopted. The present application includes multiple means for solving the above problem, and one example is an elevator car including a first member having a groove formed therein, and a second member having a fixed end that fits into the groove and is fixed to the first member by the fit between the fixed end and the groove.

[0007] According to the present invention, it is possible to provide an elevator car and an assembly method for the elevator car, which allow the main parts to be fixed without the need for fasteners such as bolts. Problems, configurations, and effects other than those described above will become clear from the description of the following embodiments.

[0009] Hereinafter, embodiments of the present invention will be described with reference to the drawings. In each drawing for explaining the embodiments and modifications, the same components are given the same reference numerals, and repeated description thereof will be omitted as much as possible.

[0010] <Elevator Car> Figure 1 is an overall configuration diagram of an elevator car 1 according to an embodiment. As shown in this figure, the elevator car 1 has a box shape consisting of a floor 10, a ceiling 20, and side walls formed by a plurality of side panels 30. An opening 30a for passengers to enter and exit the box-shaped car 1 is provided in a portion of the side wall formed by the side panels 30. A frame 40 is fixed to the outer periphery of the car 1 so as to go around the box shape along the floor 10, the side walls formed by the side panels 30, and the ceiling 20.

[0011] A feature of the passenger car 1 having such a configuration is that at least one of the plurality of side plates 30 is fixed to the floor 10 without using fastening members such as bolts. Here, the side plate 30 as a second member that is fixed to the floor 10 as a first member without using fastening members is assumed to be, for example, the side plate that is installed last when assembling the side wall of the passenger car 1.

[0012] Fig. 2 is a diagram for explaining the schematic configuration of the main parts of the passenger car 1, and shows, as an example, a side wall portion facing the opening 30a in the passenger car 1 shown in Fig. 1. As shown in Fig. 2, the passenger car 1 is formed by sequentially fixing a plurality of side plates 30 to the floor 10. For example, in a side wall constituting a single plane made up of three side plates 30, as shown in Fig. 2(1), after the side plates on both sides (hereinafter referred to as adjacent side plates 31) are fixed to the floor 10, the central one is fixed to the floor 10 as the last side plate (hereinafter referred to as final side plate 32).

[0013] Fig. 3 is a diagram for explaining the state in which the side panel 30 is fixed to the floor 10 of the car 1, and is an exploded view of the side wall portion shown in Fig. 2. Below, the configuration of the adjacent side panel 31 and the final side panel 32 and their fixed state to the floor 10 will be described with reference to Fig. 3.

[0014] <Configuration and Fixing State of Adjacent Side Plate 31> The adjacent side plate 31 is formed as a channel steel with flanges 31b protruding in one direction from both long sides of the plate material 31a. This adjacent side plate 31 also has a fixing flange 31c on the short side located below the plate material 31a. The fixing flange 31c protrudes in the same direction as the flange 31b. This fixing flange 31c has multiple bolt holes 31d used for fixing to the floor 10. Note that the adjacent side plate 31 is typically configured with reinforcing material fixed along the longitudinal direction of the plate material 31a, but the reinforcing material is not shown here.

[0015] The floor 10 is composed of a floor member 11 that forms the floor surface and a support member 12 that supports the periphery of the floor member 11, relative to the adjacent side plate 31. The floor member 11 is, for example, configured by sandwiching multiple reinforcing members between two plates. The support member 12 is made of a channel steel having a web 12a, an upper flange 12b protruding from the upper end of the web 12a, and a lower flange 12c protruding from the lower end of the web 12a. The support member 12 is positioned so as to sandwich the floor member 11 between the upper flange 12b and the lower flange 12c, and secures the floor member 11 to the lower flange 12c. There is a gap between the floor member 11 secured to the lower flange 12c and the upper flange 12b. The upper flange 12b has bolt holes 12d at positions corresponding to the multiple bolt holes 31d provided in the adjacent side plate 31.

[0016] 4 is an enlarged side view illustrating the state in which the adjacent side plate 31 is fixed to the floor 10. As shown in this figure, the adjacent side plate 31 is fixed to the upper flange 12b of the support member 12 using a bolt F1. The bolt F1 is inserted through the gap between the floor member 11 and the upper flange 12b and screwed in from below so as to pass through the bolt hole 12d in the upper flange 12b and the bolt hole 31d in the adjacent side plate 31. This operation is performed from inside the car.

[0017] 3, the final side plate 32 has a base material 32' made of a channel steel having flanges 32b protruding in one direction from the long sides of both sides of a plate material 32a, and a fixing member 300 fixed to the base material 32'. The fixing member 300 is a channel steel arranged along the longitudinal direction of the base material 32' on the surface of the base material 32' in the protruding direction of the flanges 32b, and also functions as a reinforcing member for the base material 32'.

[0018] The fixing member 300 is a channel steel with flanges 300b protruding in one direction from the long sides on both sides of the web 300a, and is provided in a state in which the web 300a is fixed to the plate material 32a of the base material 32'. The fixing member 300 is also provided protruding downward from the lower end of the base material 32', and the portion protruding downward from the lower end of the base material 32' serves as a fixed end 301 for the floor 10.

[0019] The fixed end 301 of the fixing member 300 has flanges 300b protruding from the long sides of the web 300a at partially extended lengths, with tip portions 300c on both sides of the extended flanges 300b bent inward to form a lip channel steel. This fixed end 301 is formed into a lip channel shape that fits into a groove 100 formed in the floor 10 by the procedure described below in the method for assembling the car, thereby fixing the final side panel 32 to the floor 10.

[0020] The fixed end 301 is also made of a plastically deformable material. This makes it possible to deform the fixed end 301 and fix the final side plate 32 to the floor 10 during assembly of the car, as described below. Examples of plastically deformable materials include rolled steel plates such as cold-rolled steel plate (SPCC: Steel Plate Cold Commercial) and hot-rolled steel plate (SPHC: Steel Plate Hot Commercial). These materials are used with a thickness (e.g., approximately 1.2 to 1.6 mm) that allows bending without the use of special tools. It is sufficient that at least the tip 300 c of the fixed end 301 of the fixing member 300 is made of a plastically deformable material.

[0021] For this final side panel 32, the support member 12 constituting the floor 10 has a groove 100 at a position corresponding to the fixed end 301 of the fixing member 300 of the final side panel 32. The groove 100 may be formed directly in the upper flange 12b of the support member 12, or may be formed in a plate 12e fixed to the upper flange 12b as shown. This groove 100 has a planar shape into which a lip-channel steel profile is fitted, and by fitting with the fixed end 301 of the fixing member 300 of the final side panel 32, the final side panel 32 is fixed to the floor 10. The support member 12 or plate 12e having the groove 100 is made of a steel material such as SS400 or SGHC plate with an appropriate plate thickness (for example, approximately 2.3 to 3.2 mm).

[0022] Fig. 5 is an enlarged perspective view illustrating the state in which the final side panel 32 is fixed to the floor 10. As shown in Fig. 5, the fixed end 301 of the fixing member 300 on the final side panel 32 is fitted into a groove 100 provided in the support member 12 that constitutes the floor 10, and grips the inner peripheral portion 101 surrounded by the groove 100, thereby fixing the final side panel 32 to the floor 10. The procedure for fitting the fixed end 301 into the groove 100 and gripping the inner peripheral portion 101 with the fixed end 301 will be explained in the next section on assembling the car.

[0023] FIG. 6 is a plan view (part 1) showing the configuration of the fixed end 301 of the fixing member 300 in the final side panel and the groove 100 in the floor. As shown in FIG. 6, the groove 100 is composed of a central groove 100a, side grooves 100b extending from both ends of the central groove 100a approximately perpendicular to the central groove 100a, and tip grooves 100c extending inward from the tips of the side grooves 100b. The web 300a at the fixed end 301 is fitted into the central groove 100a. The flanges 300b at the fixed end 301 are fitted into the side grooves 100b. The tip ends 300c of the flanges 300b at the fixed end 301 are fitted into the tip grooves 100c. In particular, the bent portion from the side grooves 100b to the tip groove 100c has a gently curved shape at the outer periphery bent portion A1. As a result, as will be explained below, when assembling the passenger basket, the tip of the flange 300b is easily bent toward the tip groove portion 100c along the inner wall of the outer circumferential bending portion A1.

[0024] 7 is a plan view (part 2) showing the configuration of the fixed end 301 of the fixing member 300 on the last side panel and the groove 100 on the floor, and shows the state in the middle of assembling the car. As shown in FIG. 7, the central groove portion 100a of the groove 100 has a length [La] that can accommodate the web 300a of the fixing member 300.

[0025] Additionally, the side grooves 100b in the groove 100 have a length [Lb] that can accommodate the flange 300b of the fixed end 301 when linearly extended from the flange 300b to the tip 300c. In other words, the extension length [Lb] of the side grooves 100b, including the opening width [Wa] of the central groove 100a, is longer than the extension length of the flange 300b (including the tip 300c) at the fixed end 301. This allows the linearly extended flange 300b to be inserted into the side grooves 100b when assembling the car, as will be described below.

[0026] The tip groove portion 100c has a length [Lc] sufficient to allow the fixed end 301 to grasp the inner peripheral portion 101 surrounded by the groove 100 when the tip portion 300c of the fixed end 301 is bent along the tip groove portion 100c.

[0027] The width [Wa] of the central groove 100a in the groove 100 is large enough to accommodate the fixed end 301 in two states: when it is linearly extended from the flange 300b to the tip 300c (see FIG. 7) and when the tip 300c is bent along the tip groove 100c (see FIG. 6). The width [Wb] of the side grooves 100b need only be large enough to fit the fixed end 301 from the flange 300b to the tip 300c. Furthermore, as shown in FIG. 6, a larger gap is formed around the outer periphery of the fixed end 301 accommodated in the central groove 100a than the gaps formed in the side grooves 100b and the tip groove 100c. This gap in the central groove 100a allows the fixed end 301 to move within the groove 100 during the basket assembly method described below.

[0028] Furthermore, the width [Wc1] of the proximal end of the distal groove 100c in the groove 100 is large enough to allow the linearly extended distal end 300c to bend along the outer periphery bend portion A1. The width [Wc2] of the distal end of the distal groove 100c is approximately the same as the thickness of the distal end 300c at the fixed end 301. In other words, the opening width of the distal groove 100c is formed so that it narrows from the proximal end on the side of the side grooves 100b toward the distal end. The width [Wc2] of the distal end of the distal groove 100c is preferably large enough so that when the distal end 300c is bent along the outer periphery bend portion A1 and inserted into the distal groove 100c, the distal inner wall of the distal groove 100c can clamp the distal end 300c (see FIG. 6 ).

[0029] <Method of Assembling a Passenger Cage> Figure 8 is a process diagram showing a method of assembling a passenger cage according to an embodiment, and is a perspective view and a plan view showing the procedure for fixing the final side panel 32 to the floor 10 by construction from the inside of the passenger cage 1 when assembling the passenger cage 1 previously described using Figures 1 to 3. However, the base material 32' of the final side panel 32 (see Figure 3) is not shown. Below, as a method of assembling a passenger cage, the procedure for fixing the final side panel 32 between two adjacent side panels 31 in a state where the adjacent side panels 31 are fixed to the support members 12 of the floor 10 will be described with reference to Figure 8.

[0030] First, by working inside the car, the final side panel 32 is lifted onto the top of the support member 12 that forms the floor, as shown in the perspective view (1)-a and plan view (1)-b of Figure 8. At this time, the fixing member 300 is placed on the outside of the car, with the fixed end 301 facing downward. Then, the fixed end 301 is placed in correspondence with the groove 100 provided in the support member 12. In this state, the flange 300b of the fixed end 301 of the fixing member 300 is not bent all the way to the tip 300c, but is extended linearly.

[0031] Next, by working inside the passenger cage, the final side panel 32 is lowered onto the support member 12, and the fixed end 301 of the fixing member 300 is fitted into the groove 100 of the support member 12, as shown in the perspective view (2)-a and the plan view (2)-b of Figure 8. At this time, since the fixed end 301 of the fixing member 300 is not bent, the fixed end 301 is fitted only into the central groove portion 100a and the both side groove portions 100b of the groove 100.

[0032] Next, as shown in the perspective view (3)-a and the plan view (3)-b of Figure 8, the final side plate 32 on the support member 12 is pushed horizontally toward the outside of the car (toward the tip c of the flange 300b of the fixed end 301), moving the final side plate 32 toward the outside of the car. As a result, the fixed end 301 of the fixing member 300 moves toward the tip groove portion 100c in the groove 100 of the support member 12. This action causes the tip portion 300c of the fixed end 301, which is made of a plastically deformable material, to be pressed against the outer peripheral bent portion A1 of the tip groove portion 100c and deform, and is smoothly guided along the outer peripheral bent portion A1 to bend and insert into the tip groove portion 100c. Furthermore, the web 300a of the fixed end 301 reaches the inner wall of the central groove 100a, and the tip 300c of the fixed end 301 is sandwiched between the inner and outer walls of the tip groove 100c. As a result, the fixed end 301 of the fixing member 300 grips the inner wall 101 of the groove 100, and the final side panel 32 having the fixing member 300 is fixed to the floor 10.

[0033] By fixing the final side panel 32 to the floor 10 in the manner described above, a side wall made up of a plurality of side panels 30 is formed on the floor 10, and then, as shown in Figure 1, the ceiling 20 is placed on top of the side wall and each side panel 30 is fixed to the ceiling 20, completing the box-shaped passenger car 1. Thereafter, a frame 40 is provided around the outer periphery of the box-shaped passenger car 1.

[0034] Effect of the embodiment According to the embodiment described above, it is possible to fix the final side panel 32 to the floor 10 without the need for fasteners such as bolts. Moreover, since the final side panel 32 can be fixed to the floor 10 by construction from the inside of the car 1, safety is ensured during the assembly work of the car.

[0035] <<Modification 1>> Fig. 9 is a diagram for explaining Modification 1 of the embodiment. The passenger car 1' shown in this figure differs from the passenger car 1 described using Figs. 1 to 8 in the shape of the support member 12' that constitutes the floor 10, but the other configurations are similar.

[0036] The support member 12' is a steel material with an S-shaped cross section. This support member 12' has a second web 12aa extending parallel to the web 12a from the edge of the upper flange 12b of the channel steel described in the embodiment, and a second upper flange 12bb extending parallel to the upper flange 12b from the edge of the second web 12aa. This support member 12' is arranged to sandwich the floor member 11 between the upper flange 12b and the lower flange 12c, and fixes the floor member 11 to the lower flange 12c.

[0037] The second upper flange 12bb has bolt holes 12d at positions corresponding to the plurality of bolt holes 31d provided in the adjacent side plate 31. Furthermore, the second upper flange 12bb has grooves 100 that mate with fixed ends 301 of fixing members 300 of the final side plate 32. The grooves 100 may be formed directly in the second upper flange 12bb, or may be formed in a plate 12e fixed to the second upper flange 12bb as shown in the figure. The shape of the grooves 100 is the same as that described in the embodiment.

[0038] Even with the configuration of the above variant example 1, as with the structure using the support member 12 of the embodiment, it is possible to fix the final side panel 32 to the floor 10 by construction from the inside of the car without the need for fastening devices such as bolts, thereby ensuring the safety of the car assembly work.

[0039] <<Modification 2>> Fig. 10 is a diagram illustrating Modification 2 of the embodiment, showing an example in which the fixing structure using the groove described in the embodiment is applied to another part. As shown in this figure, the fixing structure using the groove can also be applied, for example, to fixing a component 50 to a car 1. In the illustrated example, a base member 22 and a plate 23 having a groove formed therein are used to fix a box-shaped ceiling component 50 containing a sensor or the like to a support member 21 that supports the periphery of the ceiling 20. In this case, a groove is provided on the surface of the plate 23 facing the ceiling component 50. This groove is the groove 100 configured as described with reference to Figs. 6 and 7 .

[0040] 10 is provided with a fixed end (not shown) that protrudes from the surface facing the plate 23. This fixed end is the fixed end having the configuration described in the embodiment with reference to FIGS. 3 and 5 to 7.

[0041] Even when fixing the ceiling component 50 in this manner, it is possible to fix the ceiling component 50 to the support member 21 of the ceiling 20 without requiring fasteners such as bolts.

[0042] The present invention is not limited to the above-described embodiments and modifications, and includes various other modifications. For example, the above-described embodiments have been described in detail to clearly explain the present invention, and are not necessarily limited to those including all of the described configurations. Furthermore, it is possible to replace part of the configuration of one embodiment with the configuration of another embodiment, or to add the configuration of another embodiment to the configuration of one embodiment. Furthermore, it is possible to add, delete, or replace part of the configuration of each embodiment with other configurations.
