Embodiment approach 1

[0026] figure 1 It is a perspective view showing the elevator car according to Embodiment 1 of the present invention. exist figure 1 Among them, the car 1 is composed of a car room, a ceiling unit 7 forming the ceiling part of the car room, and guide shoes 8 provided on the ceiling unit 7, wherein the car room has: a lower frame 2, which has an emergency Stopping parts; car floor 3, which is provided on the lower frame 2; columns 4, which are erected at the four corners of the car floor 3; a pair of side walls 5, which form the sides of the car; front walls (not shown), which are arranged opposite to the entrance 10; car doors (not shown), which open and close the entrance 10;

[0027] When the car 1 ascends and descends in the hoistway, the car 1 is guided by guide rails 9 provided in the hoistway by means of guide shoes 8 .

[0028] figure 2 It is a perspective view which shows the ceiling unit 7 which concerns on Embodiment 1 of this invention. exist figure 2 Among ...

Embodiment approach 2

[0074] In Embodiment 1, the horizontal portion 713a of the front beam 713 is positioned higher than the horizontal portion 711a of the side beam 711 and the horizontal portion 712a of the rear beam 712, but may be provided at the same height. Figure 11 It is a perspective view showing the upper frame 71 of this embodiment. Such as Figure 11 As shown, the horizontal portion 713a of the front beam 713 is formed by bending toward the rear side of the car 1 , and the horizontal portion 713a has a screw hole 12 for connecting with the front horizontal portion 723b of the ceiling 72 .

[0075]The lower horizontal portion 711a of the side beam 711 retains the front-rear dimension of the horizontal portion 712a of the rear beam 712 from the rear end surface of the steel material, and retains the front-rear dimension of the horizontal portion 713a of the front beam 713 from the front end surface of the steel material. The amount is formed by bending the central part. Therefore, the...

Abstract

The present invention relates to a light-weight and highly rigid ceiling unit (7) and an elevator car (1) which is provided with the ceiling unit (7). The ceiling unit (7) is provided with a first side beam (711) held by at least one of a plurality of upstanding columns (4) rising from an elevator car floor plate (3); a second side beam (711) held parallel to the first side beam (711) by an upstanding column (4) among the plurality of upstanding columns (4), the upstanding column (4) being different from the upstanding column (4) holding the first side beam (711); a rear beam (712) for connecting the rear ends of the first and second side beams (711, 711); and a ceiling plate (72) held such that the lower surface thereof is in contact with the first and second side beams (711, 711) and with the rear beam (712).

Description

technical field [0001] The invention relates to a roof unit and an elevator car with a roof unit. Background technique [0002] Conventional elevators have a car frame supported by hoisting machine ropes, and the car frame is composed of a lower frame, uprights, and an upper frame. In addition, a car chamber through which passengers enter and leave is held inside the car frame. Since the car frame and the car chamber are different structures, it is necessary to ensure strength separately. For example, the upper frame of the car frame needs to be strong enough to withstand the offset load acting on the car floor of the car room, and the ceiling of the car room needs to be able to withstand the riding of maintenance workers or heavy parts during installation or maintenance. the bearing strength. In conventional elevators, it was necessary to ensure the strength of the upper frame and the ceiling separately, resulting in an increase in the number of parts and an increase in ...
