Description

[Detailed description of the invention] This invention relates to an entrance/exit door for an elevator car or the like.

Recently, there has been an increasing demand for luxurious and novel design panels for elevator cabs and the like in order to harmonize with the modern design of buildings.

In order to meet this demand, the applicant of this invention previously provided a transparent panel with a pattern engraved on the front side of an opaque panel, and illuminated it by shining light from the edge of the transparent panel with a lighting device. proposed an elevator design panel that entertains passengers by creating a luxurious and fresh design with illuminated patterns and opaque panels. By the way, this design panel is
Since it is necessary to supply power to the lighting equipment, it can be applied relatively easily to fixed objects such as the walls of the car room, but it can also be applied to parts that operate like doors that open and close entrances and exits. There is a problem with the power supply to the lighting equipment.

This idea solves the above-mentioned problems, avoids power supply using flexible cables, and supplies power to the lighting device that illuminates the pattern with the power receiver that comes into contact with the fixed power supply only when the door is fully closed. It is an object of the present invention to provide an elevator entrance/exit door using the above-mentioned design panel, which is highly reliable and has little noise.

An embodiment of this invention will be described below with reference to FIGS. 1 to 5.

In the figure, 1 is the floor of the elevator car 3, 2 is a sill provided on one side of the floor 1, and the sill 2 is provided with a guide groove 2a. 4 is an entrance provided on one side of the car room 3, 5 is a rail fixed above the entrance 4 of the car room 3, 6 is a power supply body fixed above the rail 5, and 6a is made of electrically insulating material. 6b, 6b' are fitting holes drilled horizontally near the tip of the case 6a, 6c, 6c' are power supply contacts provided at the innermost parts of the fitting holes 6b, 6b',
6d and 6d' are power supply cables that supply power to the power supply contacts 6c and 6c', 7 is a suspension wheel equipped with a roller 7a that rolls on the rail 5, 8 is a power receiver fixed to the suspension wheel 7, 8a, 8a' is a finger board made of electrically insulating material, one end of which is fixed to the hanging wheel 7, and the other end of which is connected to the fitting hole 6 of the case 6a of the power supply unit 6.
power receiving parts 8b, 8 slidably inserted into b, 6b'
It has b′. 8c, 8c' are power receiving parts 8b, 8
The power receiving contacts 8d and 8d' provided at the tip of b' are springs and are housed in the power receiving parts 8b and 8b', and press the power receiving contacts 8c and 8c' from the rear.

9 is a sliding door that opens and closes the entrance 4 horizontally;
The upper end is suspended by a hanging wheel 7, and the lower end has a guide groove 2a.
A guide 10 that slides inside is provided to open and close the entrance/exit 4. It should be noted that the opening/closing drive device for the sliding door 9 has been commonly used in the past, so illustration and description thereof will be omitted.

When the sliding door 9 is fully closed, as shown in FIG.
c' are in contact, and springs 8d and 8d' are slightly pressed,
At the same time as generating contact pressure, the power supply contacts 6c, 6
This is to ensure a reliable contact between c' and the power receiving contacts 8c, 8c'.

Reference numeral 11 denotes a box-shaped door made of steel plate, and its surface 11a is finished with a design such as painting. 12 is a design panel made of transparent glass or transparent synthetic resin; 12a;
12c is the upper edge, 12d is the lower edge, 12e and 12f are the side edges, and 13 is a cushioning material such as rubber, which is a cushioning material such as rubber. It is arranged between the design panels 12 and at the four peripheral ends of the door 11 to avoid close contact between the door 11 and the design panel 12. 15 is a lamp chamber made of a light-shielding material arranged at the upper end of the door 11; 16 is a lighting device consisting of a lamp fixed in the lamp chamber 15; 17 is a joint formed of an opaque material such as aluminum; The design panel 12 and the lamp chamber 15 are connected to the door 11. 18 is a reflection device, 18a is a joint 17
An upper reflector plate disposed on the back inclined portion 17b of the
8b to 18d are lower and side reflecting plates disposed between the joint 17, each end 12d to 12f of the design panel 12, and the joint 17, the surfaces of which are mirror-treated and chrome plated, etc., to provide high reflection efficiency. ing. Cables 19 and 19' supply power from the power receiving contacts 8c and 8c' to the lighting device 16, and are fixed to the suspension wheel 7.

In the embodiment configured as described above, when the sliding door 9 is fully closed, the power receiving body 8 comes into contact with the power feeding body 6 and power is supplied to the lighting device 16 through the cable 19.
The lamp lights up. As a result of this lighting, the light emitted from the lamp of the lighting device 16 travels toward the upper reflecting plate 18a, as shown by the broken line in FIG. The light that is refracted in the direction, transmitted downward, illuminates the pattern 12a on the way, and further reaches the bottom end 12d of the design panel 12, and the light that is diffusely reflected by the pattern 12a and reaches the side ends 12e and 12f are reflected from the bottom. plate 18b, side reflection plate 18c,
18d, the pattern 12a is illuminated more clearly, and the pattern 12a and the design of the surface 11a of the door 11 are combined to produce an excellent design effect.

In this lighting device 16, the lamp does not light up when the sliding door 9 is "open" or "closed", that is, while the power supply body 6 and the power reception body 8 are apart.

According to the power supply body 6 and power reception body 8 having the above structure, since the power supply contacts 6c and 6c' are arranged deep in the fitting holes 6b and 6b', if the sliding door 9 is in the "open" state and the power is received, Even if the body 8 is located far away, there is no risk of foreign matter such as dust adhering to the power receiving contacts 8c, 8.
There is no risk of poor contact with c′. In addition, the power receiving contacts 8c, 8c' are pushed by springs 8d, 8d', and when the sliding door 9 is fully closed, they are slightly pressed and come into contact with the power feeding contacts 6c, 6c'.
Even if there is a slight difference in level between c' or the power receiving contacts 8c and 8c', reliable contact can be made.

In addition, the power supply contact 6c, which is constantly under voltage,
Since 6c' is located at the inner part of the holes 6b and 6b', there is no fear that a maintenance worker or the like will come into contact with it, and the occurrence of an electric shock accident can be prevented.

In the above embodiment, the springs 8d and 8d' are provided on the side of the power receiving contacts 8c and 8c', but the same effect can be obtained even if they are provided on the side of the power feeding contacts 6c and 6c'.

Although the sliding door 9 of the car has been explained, it can be applied to the sliding door of the landing in the same way, and especially if it is applied to the main floor of the building (usually the first floor), a luxurious design can be created on the main floor.

As explained above, this idea includes a transparent panel with a pattern on the opaque panel that makes up the door, a lighting device that illuminates this transparent panel, and a power supply contact at the back of the fitting hole in the fixed part of the doorway. The door is provided with a power receiving contact that supplies power to the lighting device at its tip, enters the fitting hole when the door is closed, and comes into contact with the power supply when the door is fully closed. In addition, at least one of the power supply and power reception contacts is equipped with a spring action mechanism, and the electric contact is located deep in the fitting hole and comes into contact with it through the action of the spring, which prevents the adhesion of foreign matter such as dust. To provide a highly reliable and safe elevator entrance/exit door that can prevent accidents such as poor contact and electrical shock caused by contact with maintenance workers.
