Summary of the Invention

Problems to be Solved by the Invention

[0006] However, when assembling the car in the hoistway during renewal work such as elevator renovation or replacement, workers need to enter the gap between the hoistway and the car to fasten the fastening portion. However, since the gap between the hoistway and the car is very narrow, it takes a long time to assemble the car.

[0007] Therefore, the present invention aims to provide an elevator car and a method for assembling an elevator car that can significantly reduce the assembly time of the elevator car. [Means for solving the problem]

[0008] The elevator car according to the present invention is characterized in that the side panels of the car are composed of a plurality of side walls, joints are provided between adjacent side walls, and the joints and side walls are fixed together by fastening cam lock nuts provided in the joints to cam lock screws provided in the side walls.

[0009] This configuration allows the side wall and joint to be fixed from inside the elevator car.

[0010] In the elevator car according to the present invention, the angle between adjacent side walls in a plan view is preferably 90° to 180°.

[0011] The present invention relates to an elevator car assembly method in which the side panel of the elevator car is composed of a plurality of side walls, a joint is provided between adjacent side walls, cam lock screws are provided on the side walls, and cam lock nuts are provided on the joint, characterized in that the side walls are fixed to the joint by fastening the cam lock nuts of the joint to the cam lock screws of the side walls.

[0012] This configuration significantly reduces the assembly time for the elevator car. [Effects of the Invention]

MODE FOR CARRYING OUT THE INVENTION

[0015] Hereinafter, an example of an embodiment of the present invention will be described in detail. In the following description, specific shapes, materials, directions, numerical values, etc. are examples for facilitating the understanding of the present invention, and can be appropriately changed according to applications, purposes, specifications, etc.

[0016] [Car cabin] The car cabin 10 according to the embodiment will be described with reference to FIG. 1.

[0017] The car cabin 10 is a box-shaped member constituting the passenger car 5 of the elevator. According to the car cabin 10 of the present invention, although details will be described later, the assembling time of the car cabin 10 during the construction of the elevator can be significantly shortened.

[0018] The elevator is a device that places passengers or luggage on the passenger car 5 and moves the passenger car 5 vertically for transportation. The passenger car 5 has a car cabin 10, a frame 6 that supports the car cabin 10, and a door unit 8 for entering and exiting the car cabin 10 from the landing. The car cabin 10 is supported by the frame 6 via a vibration damping member (not shown).

[0019] The car body 10 has a ceiling panel 11, a front panel 12, three side panels 13, and a floor panel 14. The floor panel 14 is formed in a rectangular shape and serves as the floor surface of the car body 10. Around the floor panel 14, the front panel 12 and the three side panels 13 are erected perpendicular to the floor panel 14.

[0020] An entrance is provided on the front panel 12. A car door that constitutes the door unit 8 is installed on the entrance of the front panel 12 so as to be openable and closable. Also, a door sill is installed at the lower part in the vertical direction of the front panel 12. The car door of the door unit 8 is movably supported by the door sill.

[0021] [Side panel] Using FIGS. 2 and 3, the side panel 13 which is an example of the embodiment will be described.

[0022] As described above, the side panel 13 constitutes the sides other than the front panel 12 where the door unit 8 is provided in the four directions of the car body 10. The side panel 13 is composed of a plurality (in this embodiment, for example, three) of sidewalls 20. Here, the angle in the plan view between adjacent sidewalls 20 is 180°, and they are formed on the same plane. Also, in the side panel 13, a joint 40 is provided between adjacent sidewalls 20.

[0023] As described above, the sidewall 20 is a flat plate member that constitutes the side panel 13 and is erected perpendicular to the floor panel 14. On the side of the sidewall 20 facing the joint 40, a fastening portion 20A bent toward the outside of the car body 10 is formed. A plurality of cam lock screws 51 are provided on the sidewall 20. The number of cam lock screws 51 provided on the sidewall 20 is not particularly limited, and it is preferably determined according to the required strength of the side panel 13 when assembled as the side panel 13.

[0024] The cam lock screw 51 has a head that engages with a groove formed on the side surface of the cam lock nut 52, which will be described later, and a threaded portion that is fixed to the fastening portion 20A by a nut. By rotating the cam lock nut 52, the cam lock screw 51 and the cam lock nut 52 are tightened, and the side wall 20 and the joint 40 are fixed together. The threaded portion of the cam lock screw 51 is fastened and fixed to the fastening portion 20A by a nut so that the head protrudes toward the joint 40.

[0025] The cam lock screw 51 is sometimes called a joint shaft or cam lock bolt. The cam lock nut 52 is sometimes simply called a cam lock.

[0026] As described above, the joint 40 is provided between adjacent side walls 20 and is erected perpendicular to the floor panel 14. The joint 40 has a fitting hole 40A into which a cam lock nut 52 is fitted, and an insertion hole 40B into which the head of a cam lock screw 51 is inserted. It is preferable that the fitting hole 40A has a counterbore formed therein.

[0027] The cam lock nut 52 has a head with a cross-shaped hole and a groove formed on its side surface that engages with the head of the cam lock screw 51 described above. The cam lock nut 52 is inserted into the fitting hole 40A of the joint 40 with its head facing the inside of the elevator car 10.

[0028] The side panel 13 facing the car compartment 10 (the side wall 20 and joint 40 facing the car compartment 10) may be covered with an aesthetically pleasing sheet. This can improve the aesthetic appearance of the interior of the car compartment 10.

[0029] In the elevator car 10, the cam lock nut 52 can be tightened by turning the cam lock nut 52 from inside the car 10, thereby fixing the side wall 20 and the joint 40. This eliminates the need to enter the gap between the hoistway and the car 10 and fasten adjacent side walls 20 together, as was done in the past, during renovation work such as elevator repair or replacement, and significantly reduces the assembly time of the elevator car 10.

[0030] Furthermore, by dividing the side panel 13 into multiple side walls 20, the side walls 20 can be easily transported into the elevator shaft. This reduces the assembly time of the elevator car 10 during construction.

[0031] [Other embodiments] Using Figures 4 and 5, we will describe another example of the embodiment, the side panel 13.

[0032] As described above, the side panel 13 constitutes the sides of the elevator car 10 other than the front panel 12 on which the door unit 8 is provided. The side panel 13 is composed of multiple (three in this embodiment) side walls 20. In addition, joints 40 are provided between the side walls 20 that form the side panel 13. In other words, joints 40 are provided between the side walls 20 that form the side panel 13. The angle between the side walls 20 in a plan view is 90°, but this angle may be any angle from 90° to 180°.

[0033] Multiple cam lock screws 51 are provided on the side wall 20. The number of cam lock screws 51 provided on the side wall 20 is not particularly limited and is preferably determined according to the required strength of the car car 10 when assembled as a car car 10. In addition, the side of the side wall 20 that forms the corner has a fastening portion 20A that is bent 90° toward the outside of the car car 10. The threaded portion of the cam lock screw 51 is fixed to the fastening portion 20A by a nut and is provided so that the head protrudes toward the joint 40.

[0034] As described above, the joint 40 is provided between adjacent side walls 20 and is erected perpendicular to the floor panel 14. The joint 40 has a fitting hole 40A into which the cam lock nut 52 is fitted, and an insertion hole 40B into which the head of the cam lock screw 51 is inserted. The cam lock nut 52 is fitted into the joint 40 with its head facing the inside of the elevator car 10.

[0035] In the elevator car 10, the cam lock screw 51 and the cam lock nut 52 can be tightened by turning the cam lock nut 52 from inside the car 10, thereby fixing the side wall 20 and the joint 40. This allows the side walls 20 to be fixed together from inside the car 10. As a result, the assembly time of the elevator car 10 can be significantly reduced during renovation work such as elevator repair and replacement.

[0036] [Assembly process of the elevator car] The assembly process of the elevator car 10 will be explained using Figure 6.

[0037] In step S11, the frame 6, door unit 8, ceiling panel 11, front panel 12, floor panel 14, side wall 20, and joint 40 are brought into the elevator shaft. In step S12, the side wall 20 and joint 40 are assembled so that the cam lock screws 51 of the side wall 20 and the cam lock nuts 52 of the joint 40 interlock, and the assembly is erected on the floor panel 14.

[0038] In step S13, the cam lock nut 52 is tightened by turning the cam lock nut 52 from inside the elevator car 10, thereby fixing the side wall 20 and the joint 40. In step S14, the front panel 12 is fixed to the side panels 13, which are fixed to each other, and the door unit 8 is assembled to the front panel 12.

[0039] In step S15, the ceiling panel 11 is placed on the front panel 12 and the side panels 13, and the ceiling panel 11 is fixed to the front panel 12 and the side panels 13 from the ceiling side (outside and above the car compartment 10).
