Description

The present invention relates to an improvement in an elevator hall device that performs hall call registration in an elevator.

It is well known that elevator hall equipment is installed at an elevator hall. Except for special specifications, these devices generally have simple countermeasures against water exposure. Compared with rainwater, condensation, and cleaning water entering the elevator hall equipment, the internal electrical components may fail. The structure is vulnerable to water.

For this reason, a fence is installed in front of the elevator landing door, the floor in front of the landing door is tilted to take measures to prevent water from entering the hoistway, or a cloth that has been squeezed with a maintenance manual, etc. In order to prevent the water from entering inside the elevator hall equipment, such as encouraging the managers to recommend wiping or emptying with water.

In particular, when waterproof performance is required, a method of installing a cover on the entire surface of the elevator hall device as shown in FIG. 6 has been proposed. (Ref. 1)

In the elevator hall 17 in FIG. 6, 12 is a hall wall, an elevator hall door 16 is provided at the opening of the hall wall 12, a hall unit 15 is provided on the hall wall beside the elevator hall door 16, and the hall unit 15 Is provided with a hall indicator 13 and a hall push button 14, and the entire hall unit 15 is covered with a transparent film 18 of a waterproof device 21 of an elevator hall device, and the transparent film 18 is attached above the hall unit 15. It is supplied from a film supply shaft 19 and collected by a film collection shaft 20 attached below the landing unit 15, and the film supply shaft 19 and the film collection shaft 20 are covered with waterproof frames 24A and 24B.

JP 2010-23936 A Japanese Patent Laid-Open No. 7-334082

In an elevator that does not have special waterproof and drip-proof performance added to the elevator hall equipment, if a malfunction occurs due to water being applied to parts inside the elevator hall equipment, the moisture is already present when the broken elevator hall equipment is inspected. There was a problem that the cause was unknown due to evaporation and it took a long time to specify.

Even if it was determined that the failure was caused by water, it was not possible to determine whether it was caused by water entering from the outside or by condensation inside the elevator hall equipment.

In the case of such a failure, if the cause is condensation inside the elevator hall equipment, free repair by the manufacturer can be considered, but if it is caused by water entering from the outside, there is originally a problem with the management method of the administrator. However, although it should be repaired for a fee, it is difficult to identify the cause, or even if it is found that water is the cause, it is difficult to determine whether it is an intrusion from the outside or condensation inside. There were problems such as having to perform free repairs as a complaint.

In particular, if the elevator hall is installed in a building and the hall is not open to the outdoors, there is a low possibility of rainwater entering and there is a high possibility that it is a problem in the management method. The determination of whether water has intruded and where the intrusion route is is an important factor for clarifying the cause and clarifying the responsibility.

Have you ever pasted inside or outside of electrical products that may be used outdoors, such as radios, video cameras, cameras, mobile phones, etc., and the electrical products have been wet, such as being submerged? Labels and seals used to determine whether or not are known. (Ref. 2)

The present invention relates to an elevator landing device provided on a wall surface of an elevator, and a cover that covers an upper portion, a left and right portion, and a rear surface portion, wherein a sheet that changes in state when wet is attached to a rear surface plate of the elevator landing device. Paste inside.

According to the present invention, when an elevator hall device breaks down, first, it is possible to quickly determine whether or not it is a failure due to water, and it is possible to quickly investigate the cause and plan a countermeasure. Second, it is possible to quickly determine whether water has entered the elevator hall equipment from the outside, and there is a sign that water has entered from the outside in an installation environment where it is unlikely that rainwater will enter the elevator hall equipment. If so, there is a high probability that water has entered the elevator hall equipment due to administrative problems, and the location of responsibility can be determined based on clear evidence.

Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 shows an example of an elevator hall device according to the present invention. FIG. 2 shows another example of the elevator hall device according to the present invention. 4 and 5 show a printed circuit according to the present invention.
Parts corresponding to those in FIG. 1 shown in FIG. 2 or FIG. Moreover, about the part corresponding to FIG. 4 shown in FIG. 5, the same code | symbol is attached | subjected and the overlapping description is abbreviate | omitted.

Example 1 will be described with reference to FIG.

In FIG. 1, 1 represents an elevator hall device, 1a is a surface plate, 3 is a button switch, 4 is a water wetness detection sheet, 5 is equipped with a microcomputer for controlling the elevator hall device, an LED dot display for position display, and the like. A printed circuit and 6 is a bracket made of a steel plate or resin, which serves as a reinforcing member for the surface plate 1a of the elevator hall device 1 and mounting members for the printed circuit 5 and the button switch 3.

The water wetting discrimination sheet 4 can be exposed and affixed to the design surface, but the design of the hall is impaired, and the water wetting discrimination sheet 4 reacts even if it is cleaned with a cloth squeezed with water. Therefore, it was difficult to adopt unless a water wetness determination sheet was provided with measures to avoid these problems.

Therefore, in order to avoid deterioration in design and prevent erroneous reaction, the water wetness determination sheet 4 is stuck inside the elevator hall device 1.

The water wetness determination sheet 4 is a well-known sheet that can be determined to have been wetted by being colored by being wetted by water or by bleeding marks or the like previously printed with water-soluble ink.

For example, in FIG. 1, when the surrounding wall of the elevator hall device 1 is cleaned by wiping with water, the upper part of the elevator hall device 1 can be considered as a path for water to enter the interior of the elevator hall device 1. The water that has entered the inside of the device 1 flows down the back surface of the surface plate 1a from the top to the bottom.

As shown in FIG. 1, the water wetting determination sheet 4 is attached to the upper part of the back surface of the front plate 1 a of the elevator hall device 1.

By sticking the water wetting determination sheet 4 to the inside of the elevator hall device 1, it is possible to determine that there is a failure due to water entering the inside of the elevator hall device 1 without damaging the design. it can.

A second embodiment will be described with reference to FIG.

In Example 1, the water wetness determination sheet 4 was used as means for determining whether water had entered the interior of the elevator hall device 1 from the outside.

Example 2 shown in FIG. 2 uses a water wetting determination sheet 9 for determining whether or not condensation has occurred inside the elevator hall device 1.

FIG. 3 shows an enlarged perspective view of a two-dot chain line circle A portion showing the water wetting discrimination sheet 9 and the cover 10 in FIG.

The water wetness determination sheet 9 is attached to the bracket 6, and the cover 10 formed of a resin or a metal plate that can cover the upper, left and right parts, and the back surface of the water wetness determination sheet is attached with a double-sided adhesive tape or the like. Attaching or bonding so as to cover the water wetness determination sheet 9.

Since the lower part of the cover 10 is not closed, the moisture in the gas inside the elevator hall device 1 can freely move back and forth. Will also condense.

Since the water wetness determination sheet 9 is covered with the upper part, the left and right parts, and the back surface part, water entering from the outside does not come into contact with the water wetness determination sheet 9. Therefore, when a failure occurs in the elevator hall device 1, if the water wetting determination sheet 9 covered by the cover 10 is colored or blotted and reacts, there is a high possibility that it has failed due to condensation. It can be judged.

By implementing Example 2 in combination with Example 1, it is possible to determine whether or not water has entered the elevator hall device 1 from the outside and whether or not condensation has occurred inside the elevator hall device 1, It becomes possible to investigate the cause of failure with higher accuracy.

Failure due to flooding of elevator hall equipment is caused by short-circuiting or rusting of internal electrical components, that is, internal circuits of printed circuits and button switches.

Therefore, as shown in Fig. 4, water intrusion occurs at the time of failure by attaching a water wetness detection sheet in the vicinity of a part on a printed circuit or a button switch on which a failure is expected to occur due to short circuit or rusting. It is possible to determine whether or not there has been.

In the printed circuit 5 shown in FIG. 4, reference numeral 22 denotes a printed board, and the LED dot matrix display 7, the microcomputer 8 and the connector 11 are soldered onto the printed board. Reference numeral 9 denotes a water wetness discrimination sheet.

Printed circuits built into elevator hall equipment may be coated with a moisture barrier. The moisture-proof coating is applied by spraying or the like, and sprayed evenly on the surface of the printed circuit.

However, there are cases in which a moisture-proof agent cannot be sufficiently coated on the details of LED dot matrix displays, connectors, and the like that are tall on the printed circuit or inserted and mounted.

In such cases, short-circuiting and rusting often occur in parts that are not sufficiently coated with the moisture-proofing agent.

Therefore, as shown in FIG. 5, between the printed circuit board 22 and a part of the printed circuit 5 that may not be sufficiently coated with the moisture-proofing agent, such as the LED dot matrix display 7, the microcomputer 8, and the connector 11, for example. The water wetness determination sheet 9 is pasted, and at the time of failure analysis, the relevant part is removed and the presence or absence of water wetness is determined.

The fourth embodiment can be pursued as a cause of failure with higher accuracy by being appropriately combined with the first to third embodiments.
