[0031] The car room 10 includes 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 of the car room 10. The front panel 12 and the three side panels 13 are vertically arranged around the floor panel 14.

[0032] An entrance and exit are provided on the front panel 12. A car door constituting the door unit 8 is provided in an openable and closable manner at the entrance and exit of the front panel 12. A threshold is provided at the lower portion in the vertical direction of the front panel 12. The car door of the door unit 8 is movably supported on the threshold.

[0033] [Side panel]

[0034] use Figure 2 and Figure 3 , the side panel 13 as an example of an embodiment will be described.

[0035] As described above, the side panels 13 constitute the four sides of the car chamber 10, excluding the front panel 12 on which the door unit 8 is installed. The side panels 13 are composed of a plurality of (in this embodiment, for example, three) side walls 20. Adjacent side walls 20 are arranged at an angle of 180° when viewed from above, and are formed on the same plane. Furthermore, the side panels 13 have joints 40 between adjacent side walls 20.

[0036] As described above, the side wall 20 is a flat plate-shaped member that constitutes the side panel 13 and is vertically disposed relative to the floor panel 14. A fastening portion 20A that is bent toward the outside of the car chamber 10 is formed on the side of the side wall 20 that faces the joint portion 40. A plurality of cam locking screws 51 are provided on the side wall 20. The number of cam locking screws 51 provided on the side wall 20 is not particularly limited and is preferably determined based on the required strength of the side panel 13 when assembled.

[0037] The cam lock screw 51 has a head that engages with a groove formed on the side circumference of a cam lock nut 52 (described later) and a threaded portion that is secured to the fastening portion 20A via the nut. Rotating the cam lock nut 52 tightens the cam lock screw 51 and cam lock nut 52, securing the side wall 20 and the joint 40. The threaded portion of the cam lock screw 51 is secured to the fastening portion 20A via the nut, so that the head of the cam lock screw 51 protrudes toward the joint 40.

[0038] In addition, the cam lock screw 51 is sometimes also called a joint shaft, a cam lock bolt, etc. In addition, the cam lock nut 52 is sometimes also called a cam lock member.

[0039] As described above, the joint portion 40 is provided between adjacent side walls 20 and is vertically erected relative to the floor panel 14. The joint portion 40 is formed with a fitting hole 40A into which the cam lock nut 52 fits, and an insertion hole 40B into which the head side of the cam lock screw 51 is inserted. The fitting hole 40A is preferably countersunk.

[0040] The cam lock nut 52 has a head with a cross hole and a groove formed on the side surface that engages with the head of the cam lock screw 51. The cam lock nut 52 is inserted into the fitting hole 40A of the joint 40 with its head facing the interior of the car chamber 10.

[0041] The side panels 13 facing the car chamber 10 (the side walls 20 and the joints 40 facing the car chamber 10 ) may also be covered with a sheet having design properties.

[0042] According to the car chamber 10, the cam locking screw 51 and the cam locking nut 52 can be tightened by rotating the cam locking nut 52 from inside the car chamber 10, thereby fixing the side wall 20 and the joint portion 40. Therefore, during renovation work such as elevator modification or replacement, it is no longer necessary to enter the gap between the hoistway and the car chamber 10 to tighten the adjacent side walls 20 to each other as in the past, which can significantly shorten the assembly time of the elevator car chamber 10.

[0043] Furthermore, by dividing the side panel 13 into a plurality of side walls 20, the side walls 20 can be easily carried into the hoistway. This can shorten the time required to assemble the car room 10 during elevator construction.

[0044] [Other embodiments]

[0045] use Figure 4 and Figure 5 , the side panel 13 as another example of the embodiment will be described.

[0046] As described above, the side panels 13 constitute the four sides of the car chamber 10, excluding the front panel 12 on which the door unit 8 is installed. The side panels 13 are composed of a plurality of (three in this embodiment) side walls 20. Furthermore, joints 40 are provided between the side walls 20 forming the side panels 13. In other words, joints 40 are provided between the side walls 20 forming the side panels 13. The angle between the side walls 20 when viewed from above is 90°, but this angle may be any angle between 90° and 180°.

[0047] A plurality of cam locking screws 51 are provided on the side wall 20. The number of cam locking screws 51 provided on the side wall 20 is not particularly limited and is preferably determined based on the required strength of the elevator compartment 10 when assembled into the elevator compartment 10. Furthermore, a fastening portion 20A is formed on one side of the side wall 20 forming a corner, bent 90 degrees toward the outside of the elevator compartment 10. The threaded portion of the cam locking screw 51 is secured to the fastening portion 20A by a nut, and the head of the cam locking screw 51 is arranged to protrude toward the joint portion 40.

[0048] As described above, the joint portion 40 is provided between adjacent side walls 20 and is vertically erected relative to the floor panel 14. The joint portion 40 is formed with a fitting hole 40A into which the cam lock nut 52 fits, and an insertion hole 40B into which the head side of the cam lock screw 51 is inserted. The cam lock nut 52 is fitted into the joint portion 40 with its head facing the interior of the car chamber 10.

[0049] According to the car chamber 10, the cam locking screw 51 and the cam locking nut 52 can be tightened by rotating the cam locking nut 52 from inside the car chamber 10, thereby fixing the side walls 20 and the joint portion 40. Thus, the side walls 20 can be fixed to each other from inside the car chamber 10. As a result, the time required to assemble the elevator car chamber 10 can be significantly shortened during renovation work such as elevator reconstruction or replacement.
