Problems solved by technology

The problem with these solutions is that it is difficult for a person to open the suspended ceiling, because the more screws he / she opens, the more the roof panel tends to open at the same time, and often the more it warps downwards unevenly
It is also difficult for one person to fix the suspended ceiling back into place
A disadvantage of this solution is also that the fixing of the fixing elements can be easily forgotten during the fixing phase, in which case the fixing of the suspended ceiling is weakened and the suspended ceiling can suddenly fall down on the passengers of the elevator due to vibrations and other forces overhead
Another problem is that if the fixed elements are only supported by the surface below them, the fixed elements can generate noise when the elevator is running, which noise is caused by various vibrations of the elevator car

Embodiment Construction

[0028] figure 1 A simplified schematic side view showing the top of an elevator car 1 with a suspended ceiling 3 of the elevator car 1 equipped with a locking device 5 and a light source 4 according to the invention, which act as a lock The action of the closing means or fixing means, the suspended ceiling opens from its first edge and is equipped with hinges 6 on its second edge, it is seen in its normal position, indicated by the solid line, ie its upper position, and by The part indicated by the dashed-dotted line is lowered. The bottom edge of the roof of the elevator car 1 is marked with reference numeral 2 . The locking of the suspended ceiling 3 into its normal working position is achieved by means of a locking device 5, which is provided on the top surface of the suspended ceiling 3, near the edge on the opposite side of the hinge 6 of the suspended ceiling 3, and is provided On the side edges of the suspended ceiling 3 there are a total of two locking devices, one o...

Abstract

The object of the invention is a method and an arrangement for opening and closing a suspended ceiling or corresponding of an elevator car and also a locking device. The suspended ceiling or corresponding is supported in place at least partly by one or more locking devices. In the method the suspended ceiling or corresponding is opened from its locking and lowered away from its position and fixed again into its position. In the opening phase of the suspended ceiling the locking devices supporting the suspended ceiling are pre-tuned into a state where the suspended ceiling continues to stay in place in the upper position and after pre-tuning the suspended ceiling is released from its locking by lifting the suspended ceiling first upwards and after this by letting the suspended ceiling lower downwards.

Description

technical field [0001] The object of the present invention is a method and a device for opening and closing a suspended ceiling or equivalent of an elevator car and a locking device. Background technique [0002] In the following, the method, the device and the locking device according to the invention are collectively referred to as the solution according to the invention. [0003] The ceiling of the elevator car, ie the suspended ceiling, often includes a number of light sources for illuminating the elevator car. The lamps of these light sources must be replaced from time to time. In addition, the space between the suspended ceiling and the car roof often includes various equipment that requires periodic maintenance. For this purpose, access to the space between the suspended ceiling and the cabin roof is actually absolutely necessary. Doors are often arranged from below, in which case the ceiling of the car must be able to be lowered to some extent to be able to get in...
