JPS5851183Y2 - Inspection gate at elevator entrance/exit - Google Patents

Description

[Detailed Description of the Invention] The present invention relates to an inspection port provided on the inside of the tower in the upper frame of the elevator hall entrance.

On the surface of the upper frame of the elevator entrance/exit door facing the elevator hall, position indicator lights, direction lights, etc. are provided to inform passengers of the driving direction of the car, etc.

These are displayed by storing incandescent lights inside and making them blink, but in order to perform maintenance and inspection in case of burnt out bulbs, etc., there is an inspection hole inside the tower above the entrance/exit of the landing.

The structure of a conventional inspection port will be explained with reference to FIGS. 1 and 2.

In Figures 1 and 2, 1 is the upper frame of the entrance/exit of the hall bent into a roughly shaped shape, 1a is the back plate facing the inside of the tower, 2 is the hall position indicator, 3 is the door of the elevator hall, 4 Reference numeral 5 indicates an inspection port provided in the back plate 1a facing the inside of the tower of the upper frame of the landing, 5 a lid covering the inspection port 4, and 6 a screw for attaching the lid 5.

Due to the above structure, the lid 5 fixed to the back plate 1a facing the inside of the tower on the upper frame of the landing can be installed by loosening the screws 6, and then being placed on the top of the car and placed in the landing position. Maintenance and inspection of display unit 2 was being carried out.

Therefore, there were the following drawbacks. - There is a risk of losing the screws 6 that attach the lid 5 because they are removed from the back plate 1a of the upper frame facing the inside of the tower.

＠ Maintenance and inspection are carried out on a car with poor footing, so with such a complex structure, maintenance and inspection takes too much time.

Further, the place where the removed lid 5 can be placed is limited to a very limited place, which is inconvenient.

O Since you have to hold the tool in one hand and grasp the lid 5 with the other hand to remove it, you cannot support your body and it is dangerous to carry out maintenance and inspection by yourself.

This invention was made to eliminate the above-mentioned drawbacks.
This allows maintenance and inspection of the landing position indicator 2 to be performed easily.

Hereinafter, the present invention will be explained with reference to an embodiment shown in the drawings.

In FIG. 3, FIG. 4, and FIG. 5, 15 is a plate-shaped body 15a.
, 15b of the present invention, 7 is a hinge, and one piece 1a of the lid is a hinge.
is fixed to the lower part of the back plate 1a of the upper frame of the entrance facing the inside of the tower, and the other piece 7b is fixed to one end of the plate-like body 15b.

8 is a pin provided on the back plate 1a of the upper frame of the entrance facing the inside of the tower.

Reference numeral 9 is a rivet that connects the plate-shaped body 1 so that the lid 15 can be expanded and contracted.
A long hole 10 is provided in the plate 15a, and the plate 1 is inserted along the plate 15b.
5a is engaged by a rivet 9 so that it can slide.

Further, a daruma hole 11 is provided in the upper part of the plate-shaped body 15a.

Next, the opening/closing operation of the lid according to the present invention will be explained.

In the state shown in FIG. 3, the solid line indicates the state in which the lid 15 is completely closed.

When performing maintenance as the first operation, the plate-like body 15a is pulled up to the position indicated by the two-dot chain line.

In this state, the pin 8 provided on the upper part of the back plate 1a facing the inside of the tower of the upper frame of the entrance, the rivet 9 engaging the plate-like bodies 15a and 15b, and the rivet 9 provided on the plate-like body 15a. The two-dot chain line in FIG. 5 shows the positional relationship between the elongated hole 10 and the Daruma hole 11.

As a second operation, the lid 15 is opened to the position indicated by the two-dot chain line in FIG. 4 using the hinge γ as a fulcrum and placed on the folded part 1b of the landing frame upper frame.

Furthermore, in the third operation 7, the plate-like body 15a is contracted to the position shown by the solid line in FIG. 4, and the opening operation of the lid 15 is completed.

When closing the lid 15, the above operation may be performed in reverse.

It goes without saying that the landing door 3 must be opened as the first stage of maintenance.

With this structure, there is no need to remove the screws that attach the lid each time maintenance is performed, so no tools are required, and during maintenance, the lid can be easily opened by simply placing it on the folded part of the landing frame. If it is shortened, it will not get in the way during maintenance, and maintenance and inspection can be easily performed, and the time for maintenance and inspection can be shortened.

Furthermore, since maintenance can be performed sufficiently with one hand, the body can be supported with the other hand, reducing the risk of maintenance and inspection.

As explained above, the present invention has a structure in which the lid covering the inspection opening is extendable and can be hung on the Zen, so that maintenance and inspection can be carried out safely and quickly.
