Problems solved by technology

[0003] However, since the control box 7 must be fixed on the upper surface of the car 1 after the car frame 2 is assembled, and the components of the car 1 should be connected to the car frame 2, there is such a conventional elevator car. The problem is that the assembly efficiency is low due to the many steps required to assemble the elevator car on site
[0004] In addition, in the conventional elevator car, since the control box 7 must be placed at a position that does not interfere with the upper frame 5 of the car frame 2, not only is it difficult to arrange components above the car 1, but also Can interfere with maintenance / overhaul due to the limited space on the upper surface 6 of the car 1 for the operator to enter during maintenance / overhaul

Embodiment Construction

[0017] As a way to solve the above-mentioned problems, the invention of the present patent application is constructed so that, after providing a car frame for supporting the car, that is, a lower frame for supporting the bottom surface of the car and standing upright from each side of the lower frame A pair of side frames protruding ground and an upper frame for connecting the pair of side frames above the car, and in an elevator car in which a control box containing a control panel for controlling a motor is provided on the upper part of the car , the control box is embedded in the upper frame, so that the upper frame forms a part of the wall of the control box.

[0018] In the present invention, since the control box can be embedded in the upper frame during the assembly process of the elevator car, the step for installing the control box above the car is no longer necessary. In addition, since the control box is embedded in the upper frame, it is no longer necessary to prov...

Abstract

A main body (17) of controller box (16) is attached to the lower surface of upper frame (15) of car frame (11) such that it can slide freely, and upper frame (15) is configured such that it constitutes a part of a wall of controller box (16).

Description

technical field [0001] The invention of this patent application relates to an elevator car that can be raised or lowered by means of ropes. Background technique [0002] As shown in FIGS. 6 and 7 , a car frame 2 in an elevator car is generally arranged to surround a car 1 , and the car 1 is supported by the car frame 2 . The car frame 2 is constructed to have: a lower frame, not shown, which supports the bottom surface of the car 1; a pair of side frames 3 and 4, which protrude upright from each side of the lower frame; 1 above the upper frame 5 connecting the pair of side frames 3 and 4. In addition, a control box 7 is fixed on the upper surface 6 of the car 1, and a control panel (not shown) for controlling a motor that can open and close the car door is accommodated in the box body 7 . [0003] However, since the control box 7 must be fixed on the upper surface of the car 1 after the car frame 2 is assembled, and the components of the car 1 should be connected to the ca...
