Description

  The present invention relates to an elevator operation panel installed in an elevator car or an elevator hall.

  In an elevator car or an elevator hall, an elevator operation panel having operation buttons for a user to perform basic operations such as opening / closing an elevator door, designating a destination floor, and calling a car is installed. The operation button is formed of a translucent resin, and lights up when pressed to notify the user whether or not an input operation has been accepted.

  In the panel of the elevator operation panel, these operation buttons are inserted and arranged in the opening of the panel. By selectively pressing these operation buttons, the user opens / closes a door, designates a destination floor, calls a car, and the like.

On the back side of each operation button, a switch box unit including switches, LEDs, lamps, and the like is disposed so as to face the back side of each operation button. A storage box that integrally stores these switch box portions is attached to a sleeve wall of an elevator car or an elevator hall wall. A panel is arrange | positioned in the storage box front surface (for example, refer patent document 1).
JP2004-182371

  However, since the operation buttons are generally held only by the panel, when the panel is removed from the sleeve wall of the elevator car for inspection work etc., the operation button will not be pressed and will fall off from the panel. . On the other hand, a structure in which a button holding frame that holds a series of operation buttons independent of the panel is arranged between the panel and the switch box is conceivable, but even if only one button is removed, the button holding frame must be removed. Goodbye. Of course, since the panel or button holding frame is removed from the vertical sleeve wall, other operation buttons may fall. Further, in the case of a general circular operation button, it is easy to cause a rotational deviation during long-term use or attachment work, and it is difficult to recognize the inclination of the sign, letters, and numbers.

  In addition, there is a structure in which buttons are individually fixed, a circular button is provided with an anti-rotation claw, and the back side of the button is square, but the manufacture of the buttons is complicated and the fixing method is also complicated.

  It is an object of the present invention to obtain an elevator operation panel that prevents the operation buttons from falling off and falling off from the panel, and also prevents rotation even with a circular button, thereby making it possible to improve the efficiency of inspection work such as adjustment and maintenance. Is.

One embodiment of the present invention is an operation button provided to face the switch box;
A panel having a button opening for inserting and holding the operation button, and a switch box operable by pressing the operation button;
An elevator operation panel is provided between the switch box and the panel, and includes an adhesive sheet that adheres to the back surface of the panel and the operation button and holds the operation button.

  According to the present invention, it is possible to prevent the operation button from falling off or dropping out from the panel, and even a circular button is prevented from rotating. Therefore, the efficiency of inspection work such as adjustment and maintenance can be improved.

  Embodiments of the present invention will be described below with reference to the drawings. The present embodiment is an example in which the present invention is applied to an elevator operation panel for a car installed in an elevator car, that is, a car operation panel. As shown in FIG. 1, the car operation panel 10 is installed on a sleeve wall 22 on the side of the car door 21, and is used when a passenger in the car 20 performs an operation such as a predetermined floor stop. As shown in FIGS. 2 and 3, the car operation panel 10 is attached to the opening attachment portion 23 provided in the sleeve wall 22 so that the opening front of the switch box 12 fixed in the storage box 11 faces the inside of the car 20. It is closed and installed by the panel 13.

  As shown in FIG. 4, the switch box 12 includes a switch 14 and a light source unit 15 such as an LED or a lamp. The switch box 12 includes a display 30 (FIG. 2) that displays the current position of the car with a floor number. The switch box holder 11a is fixed and stored. The switch 14 includes a switch for instructing opening / closing of the car door 21, a switch for designating a destination floor, and various switches for adjusting the environment in the car.

  On the panel 13 side, an operation button 16 having translucency is arranged in a state separated from the switch, and the switch operates when pressed. The operation button 16 includes buttons on which various information is written such as door opening / closing buttons 16a and 16b, floor number buttons 16c to 16f, and emergency buttons (not shown). . Although a circular operation button is shown here, it may be a square or the like.

  A light-transmitting single-sided adhesive sheet 17 made of a thin synthetic resin is interposed between the panel 13 and the switch box 12. The adhesive sheet 17 is arranged so that the adhesive surface faces the operation button 16 side. The adhesive sheet 17 is arranged so as to cover all the operation buttons, and adheres to the back surface of the operation buttons 16. As the single-sided pressure-sensitive adhesive sheet, for example, a transparent polypropylene film coated with an acrylic resin-based pressure-sensitive adhesive can be used. For example, the film thickness may be about 0.07 mm, and the adhesive strength may be about 0.5 (N / 20 mm).

  That is, the panel 13 is provided with a button opening 13 a that projects and holds the operation button 16 on the front surface so as to be slidable in the pressing direction. When the operation button 16 is pressed, the operation button 16 is pressed and the sheet 17 is interposed. Then, the light diffusion plate 18 in the switch box 12 is pushed and the switch 14 is operated. Then, the light source unit 15 emits light and a command signal is sent to a control device (not shown) that controls the entire elevator. In addition, the information display unit of the operation button is illuminated by the light emitted from the light source unit 15 through the diffusion plate 18, the adhesive sheet 17 and the operation button 16. Since the spring 19 is installed in the switch box 12, the pressed operation button 16 is pushed back through the light diffusion plate 18 by the restoring force of the spring and returns to the initial position. Since the adhesive sheet 17 is thin and flexible as described above, the operation of the operation buttons and the switch operation are not affected.

  Further, the adhesive surface 17a of the adhesive sheet 17 is adhered to the panel back surface 13c and the operation button back surface 16a in a state where it can be peeled relatively easily and without tearing. Therefore, all the operation buttons fitted to the panel 13 are not detached from the panel 13 even if the panel 13 is turned over.

  Then, when the panel 13 of the car operation panel 10 on the sleeve wall 22 forming the vertical surface of the car 20 is removed, the operation buttons 16 are removed together with the panel 13, and these operation buttons 16 are held on the panel 13 by the adhesive sheet. Can be kept. Therefore, the operation button 16 does not fall and fall apart. Further, since the positional relationship between the operation button 16 and the panel 13 is kept constant, the operation button 16 is not rotated even if it is circular. In addition, since the adhesive sheet 17 can be easily replaced, it can be easily replaced even if the adhesive sheet 17 is contaminated or deteriorated.

  Of course, a plurality of adhesive sheets can be arranged for each operation button, or several can be arranged together. By adhering individual pressure-sensitive adhesive sheets to the back of the operation button and the vicinity of the back of the panel, even if a specific operation button is damaged, only the pressure-sensitive adhesive sheet of the corresponding operation button may be removed and replaced.

  Furthermore, in order to facilitate the arrangement of the adhesive sheet, it is desirable that the back surface 16a of the operation button 16 is substantially flush with the panel back surface 13c.

  The present invention can be applied not only to an elevator operation panel for a car having a relatively large number of operation buttons, but also to an elevator operation panel for an elevator hall.
