Description

  The present invention relates to an elevator button switch operated by a passenger and mounted on an in-car operation panel installed in an elevator car, a call button device at a landing, and the like, and an elevator apparatus including them.

  Conventional pushbuttons for elevators have been proposed that have convex characters and symbols as a character display with good visibility for healthy people and good tactile recognition with fingers etc. for visually handicapped people. (For example, refer to Patent Documents 1, 2, and 3).

  For these pushbuttons, metal (for example, stainless steel) is used as the operation surface and resin is used as the convex characters / symbols to improve the anti-tampering property and give a high-class feel. Pushbuttons are known. However, for characters having islands that are separated from the outer periphery and the inner periphery, such as “0” and “8”, the island is not separated from the surrounding metal during molding.

  Conventionally, the method of integrally molding the metal plate and the resin is different in the coefficient of thermal expansion. Therefore, the metal plate is provided with a uniform notch or the like in the portion sandwiched between the resins while improving the adhesiveness. There has been proposed a technique that makes it difficult to be influenced by the above (see, for example, Patent Document 4).

JP 2003-12248 A JP 2004-315097 A Japanese Patent Laying-Open No. 2005-0697900 JP 2002-191508 A

  When the operation surface is a metal push button and a character / symbol is to be formed of a resin, there is a problem in the adhesion between the resin and the metal because the materials are different. Therefore, it is conceivable to use the technique disclosed in Patent Document 4 or the like. However, in the pushbutton in which the operation surface is made of metal and the character / symbol is formed of a resin having a convex shape, the character / symbol is formed when the character / symbol is formed. Considering the size, it is difficult to provide a uniform notch or the like for improving the adhesion because the metal plate cannot be sandwiched between the resin.

  Furthermore, even if a notch hole is provided and the metal is sandwiched with resin, when considering the specifications such as illuminating characters and symbols by irradiating light from the back of the button, the notch hole will pass through the resin. Since it will be exposed, the design will be significantly reduced. Therefore, the conventional technique cannot be applied.

  Similarly, for characters with islands such as “0” and “8”, if the island is not separated from the surrounding metal during molding, the island and surrounding metal will be turned on when the character / symbol is lit. The bridge connecting the two will be exposed and the same problem will occur, and the design will be lowered.

  An object of the present invention is to provide an elevator pushbutton switch and an elevator apparatus that have improved adhesion between a metal that is an operation surface and a resin that forms characters and symbols, and that is excellent in design.

  In order to achieve the above object, the present invention provides a button switch provided in an elevator car or an elevator hall or both an elevator car and an elevator hall, wherein the button switch is a button operation made of metal. A display information hole is provided on the button operating surface of the bottomed cylindrical button switch surface member composed of a surface and a cylindrical portion by removing display information such as numbers, letters, symbols, etc., and the button switch surface The resin is filled so as to cover the inner surface from the back surface side of the member, and the resin is formed from the display information hole of the button switch surface member to protrude from the button operation surface surface side, so that resin formation display information is formed, and the resin The formation display information is generated when the display information hole is punched in the button operation surface. Was profile covered by the resin.

  By integrally molding in this way, part of the metal can be sandwiched between the resins, and the adhesion can be improved. Further, the resin is filled so as to cover the inner surface from the back surface side of the button switch surface member, and the formed island is removed without providing a bridge or the like for connecting the punched island portion to the surrounding metal. According to the information, the part of the island also has an outer shape that covers the drainage generated in the periphery with resin, so the button switch surface member and the resin are firmly attached without providing a bridge, and the island is also firmly held by the resin Is done.

  In addition, since the characters and symbols are punched out, there is no uniform notch or the like by using a resin with high light diffusion efficiency, so that the design is not deteriorated even when the lamp is lit.

  ADVANTAGE OF THE INVENTION According to this invention, the adhesiveness of an operation surface and a character and a symbol can be improved, and the pushbutton switch for elevators which was excellent in the designability, and an elevator apparatus provided with the same can be obtained.

This is operated when the destination floor of the car 1 is designated, the door 2 is opened and closed, and the car 1 is called from the landing.

  In the push button switch 6 in the present embodiment, the button portion 7 is made of metal (mainly stainless steel) in order to improve tamper resistance and to give the design a high-class feeling. Even in this case, it is desirable that the characters / symbols are convex so that visibility and a visually handicapped person can recognize and operate by touch.

  In order to form the button switch surface member 8 with metal and the characters / symbols 9 with resin, it is a means to reduce the manufacturing cost by making the metal and resin as an integral molded product. It is necessary to improve adhesion.

  FIG. 2 is a side view of the pushbutton switch shown in FIG. In the push button switch 6 in the present embodiment, in order to improve the adhesion with the resin, first, the metal forming the button switch surface member 8 which has been flat is subjected to drawing processing to form a cylindrical portion by providing a rise. . That is, the button switch surface member 8 has a bottomed cylindrical shape including a button operation surface and a cylindrical portion made of metal (see a cross-sectional view of FIG. 7 described later). Then, an inverted trapezoidal notch 8a as shown in FIG. 2 is processed in the cylindrical portion of the button switch surface member. The notch 8a is provided at the outer peripheral end of the cylindrical portion of the button switch surface member 8 so as to become narrower toward the end. Further, a display information hole is formed by performing punching processing from the surface side of the button switch surface member 8 according to the shape of display information such as floor letters and opening / closing pictograms. Thereafter, the character / symbol 9 is formed by filling the resin 9a from the back surface of the button switch surface member 8. At this time, the notch 8 a is also filled with the resin 9 a filled on the back surface side of the button switch surface member 8. By forming in this way, the back side of the button switch surface member 8 is filled with resin to cover the inner surface of the back side of the button switch surface member 8, and the resin covering the back side is filled into the notch 8a. It is firmly and integrally fixed so as not to fall off from the switch surface member 8.

  FIG. 3 is a partially enlarged view of a character / symbol portion in the AA cross section shown in FIG. Further, in the present embodiment, when the resin 9a is filled from the back surface of the button switch surface member 8, the resin 9a is projected from the display information hole portion that has been punched out to the front side, and the resin 9a is the resin formation display information. A character / symbol 9 is formed. At this time, the character / symbol 9 which is the resin formation display information formed by the resin 9a is generated around the display information hole when the display information hole is cut out by cutting out the display information such as the character / symbol. The outer shape is covered with the resin 9a up to the sag. With such a configuration, the button switch surface member 8 is sandwiched between the resin 9a filled from the back surface and the characters / symbols 9 formed by the resin 9a formed by projecting the resin 9a to the front surface side as shown in FIG. Further, the adhesion can be improved.

  Here, by punching out the metal from the front surface, the button switch surface member 8 is intentionally generated to be sandwiched with resin, and by filling the resin from the back surface, the molding gates and the like are on the design surface. It can be prevented from appearing. Furthermore, since the sagging sagging 8b is covered with the characters / symbols 9, the button portion 7 is excellent in design. Further, by using a resin having a high light diffusion efficiency, the characters / symbols 9 can be lit uniformly when lit.

  FIG. 4 is a front view of a character having a conventional island and a character having an island according to the present embodiment. As shown in FIG. 4, even in the case of characters with islands such as “0” and “8”, as shown in FIG. Had to have a bridge 80d. However, by integrally molding as described above, as shown in FIG. 4 (b), the character 9b filled with the character island 8c separated by the punching process from the back surface and the characters / symbols which are the resin formation display information 9, the character bridge 80d as shown in FIG. 4A can be eliminated.

  This state is shown in FIG. FIG. 5 is a partially enlarged view of the island portion shown in FIG. In this embodiment, the display information is punched by filling the resin 9a from the back surface while holding the surface of the character island 8c separated by punching so as to be substantially flush with the surface of the button switch surface member 8. The resin 9a is projected from the hole to the front side, and the character / symbol 9 which is the resin forming display information of the outer shape is covered with the resin 9a until the sag when the display information hole of the character / symbol is cut out by the projected resin 9a. Form. By doing so, in addition to the resin 9a and the button switch surface member 8 being firmly integrated, the back surface of the island 8c is supported by the resin 9a, and the periphery of the island 8c is filled from the back surface. 9a and the character / symbol 9 are firmly held.
