Description

  The present invention relates to an elevator pushbutton switch that receives an operation input by an elevator user, and relates to a waterproof pushbutton switch that prevents water from entering a lamp base that constitutes a switch portion.

Elevators installed on large ships and elevators installed outdoors such as stations, or indoor elevators are constantly exposed to the risk of water intrusion for cargo and kitchens, so a waterproof structure is desired. .
Generally, the pushbutton switch is used in a state where the pushbutton portion is exposed from the mounting hole of the front panel. Therefore, when cleaning the elevator or outdoor elevators, there is a risk of water intrusion from between the pushbutton and the cover of the pushbutton during stormy weather. There is a problem that the light source for use is short-circuited.

  Therefore, in order to prevent water and dust from entering the switch portion inside the button with an elevator push button switch, for example, an annular seal member as shown in JP 2006-331813 A is interposed. There is something. Further, as disclosed in Japanese Patent Application Laid-Open No. 10-149735 of Patent Document 2, a rubber dustproof and cushioning material is fitted to the lower part of the key switch, and a plate-like dustproof and cushioning material is interposed on the upper surface of the switch mounting plate. Can be seen.

  However, when the seal member found in Patent Document 1 is interposed, the seal member itself must be further waterproof, and the seal member itself is complicated, such as changing the thickness of the member between the movable seal portion and the fixed seal portion. It is expensive. Furthermore, in the means found in Patent Documents 1 and 2, in an elevator installed outdoors or the like, the seal material in the pushbutton switch is likely to deteriorate due to the influence of temperature, weather, etc., and it is difficult to maintain waterproofness, and long-term stability. Such use is not expected and requires maintenance.

  Accordingly, the present invention is intended to provide a waterproof pushbutton switch for an elevator that can maintain waterproofness with a simple configuration without greatly changing the structure of the pushbutton switch and can withstand long-term use.

  In order to achieve the above object, the present invention comprises a push button portion mounted on a push button mounting base having a transparent button top and a flat diamond plate and a dial plate, and a lamp base disposed on the lower surface thereof. A push button switch comprising a switch portion having a built-in contact portion main body, characterized in that a transparent silicon watermark plate is closely attached between the push button portion and the contact portion.

  The invention according to claim 2 is that the watermark plate is interposed in a stepped manner in the contact portion main body, the outer periphery thereof is in close contact with the inner wall of the stepped portion, and the pressing frame plate is laminated on the upper surface thereof. Features.

  According to the present invention, the watermark plate is a transparent plate made of silicon, which is in close contact with the inside of the contact portion main body and serves as a packing that prevents water from entering the lamp base of the internal base. Transmits the light from the LED mounted on the lamp base and illuminates the button top. Furthermore, since the watermark plate is made of flexible silicon, the switch presser plate in the contact body is pushed down in the state of the surface when receiving the pressing force of the pushbutton, contributing to the smooth operation of the switch. can do. Further, according to the present invention, the push button portion and the switch portion can be separated, and only the button portion can be replaced when the button portion becomes dirty or damaged.

It is a cross-sectional surface showing the pushbutton switch of the present invention. It is a disassembled perspective view which shows the components structure of a pushbutton part. It is a disassembled perspective view which shows the components structure of a switch part.

  Hereinafter, the present invention will be described in detail with reference to the illustrated embodiments. FIG. 1 shows a longitudinal section of the structure of a waterproof pushbutton switch (hereinafter simply referred to as “pushbutton switch”) according to an embodiment of the present invention, where 1 is a pushbutton switch attached to a surface plate 2. The push button switch 1 is roughly divided into a push button part A and a switch part B. In the push button portion A, a push button 3 made of a transparent material having a button top 31 exposed on the surface plate 2 is formed by laminating a flat and transparent diamond plate 4 and a dial plate 5 inside the support frame 30. The base 32 is supported by the push button mounting base 7 with the mounting frame base 6 interposed therebetween. Reference numeral 8 denotes a cover member of the push button 3.

  A switch part B is connected to the lower surface of the push button part A to constitute a push button switch 1 as a whole. A contact portion main body 9 is attached to the lower surface of the mounting frame base 6 of the push button portion A. The contact portion main body 9 has a transparent connecting button 10 placed on the upper surface, and a transparent silicon watermark plate 11 is interposed in close contact with a step portion 9 a inside the contact portion main body 9 by a presser frame plate 12. The outer periphery of the watermark plate 11 is provided in close contact with the inner wall 9b of the step portion 9a. The silicon watermark plate 11 prevents external water or the like from entering the switch portion B from the push button portion A.

  In addition, a transparent switch pressing plate 13 is interposed in the contact portion main body 9 in contact with the silicon watermark plate 11, and a spring 15 is interposed so that the bottom surface 13 a of the switch pressing plate 13 contacts the lamp base 14. Is stored and stored. The lamp base 14 includes an internal base 17 having a lighting LED 16 attached to the bottom of the contact portion main body 9.

  A return spring 18 is interposed between the push button part A and the switch part B. In other words, a plurality of springs 18 are interposed in the stepped portion 9a of the contact portion main body 9 to urge the push button 3 in a direction to return against the pressing force.

Next, the operation of the push button switch of the present invention will be described.
When the elevator user presses the button top 31 of the push button 3, the connection button 10 accommodated in the push button 3 is resisted against the spring 18 by the push button base 32 supported by the push button mount 7. The convex surface 10a formed at the bottom center of the bottom surface presses against the surface of the watermark plate 11 passed to the contact portion main body 9 constituting the switch portion B.

  When the watermark plate 11 is pressed, the switch pressing plate 13 housed on the lower surface is pressed and lowered, and its bottom surface 13a comes into contact with a switch circuit (not shown) of the internal base 17 in the lamp base 14, and the light source LED 16 is connected. Make it emit light.

  The light emitted from the LED 16 passes through the transparent switch press plate 13, the transparent watermark plate 11, and the transparent connection button 10 to reach the transparent push button 3, and illuminates the button top 31. That is, the light emission of the LED 16 passes through the transparent diamond plate 4 through the dial plate 5 inside the push button 3 and reaches the button top 31.

  When the push button 3 is released, the push button portion A is returned by the spring 18 in the reverse direction, and the push button portion A and the contact portion main body 9 of the switch portion B are separated. The energization of the internal base 17 in the lamp base 14 is released, and the light emission of the LED ends.

  In the present invention, the transparent silicon watermark plate 11 is passed to the step portion 9a in the contact portion main body 9 and the periphery thereof is brought into close contact with the inner wall 9b of the step portion 9a, and the presser frame plate 12 is laminated thereon. As a result, the watermark plate 11 acts as a packing against the ingress of water from the outside, and prevents the ingress of water into the lamp base.

  Further, since the watermark plate 11 is made of a silicon material, it maintains flexibility, and when the push button 3 is pressed, when the press button 3 is pressed against the convex surface 10a at the center of the connecting button 10, the pressing pressure is maintained. Can be evenly distributed and transmitted to the switch pressing plate 13 on the lower surface in a surface contact state, thereby obtaining a smooth operation of the switch.

  Since the watermark plate 11 is made of transparent silicon, it can transmit light emitted from the LED in the lamp base 14 and functions as a waterproof member as well as a translucent member.

  In the present invention, since the push button portion A constituting the push button switch and the switch portion incorporating the lamp base can be separated from each other, when the push button portion is damaged or soiled, the push button portion is left as it is. Can be exchanged only, which can contribute to reducing the cost burden on the user.
