The button cap 11 is formed by drawing or bending a metal plate.

  The thickness of the button cap 11 is reduced by reinforcing the molded body 13. In this example, the thickness of the button cap 11 is set to 0.3 mm or less. Thereby, the curvature radius R of the bending part 31 located in the boundary of the surface board part 14 and the side board part 15 becomes small, and a bending part comes to give the elevator user a sharp impression. Thereby, the designability of the button cap 11 is ensured.

  The button cap 11 is provided with a display hole 16 that penetrates the front plate portion 14. For example, the display hole 16 has a predetermined shape such as an arrow, a number, a character, or a symbol, thereby performing a predetermined display for the elevator user. In this example, as shown in FIG.1 and FIG.3, the shape of the display hole 16 is made into the shape of the arrow for selection of the destination direction by an elevator user. The display hole 16 is formed by press punching a metal plate.

  The adhesive layer 12 is provided only on the back surface of the front plate portion 14. Further, the bonding force of the adhesive layer 12 to each of the metal constituting the button cap 11 and the resin constituting the molded body 13 is higher than the bonding force of the molded body 13 to the metal constituting the button cap 11. The adhesive layer 12 is a layer having a predetermined heat resistance that can withstand the injection heat of the resin during the insert molding of the molded body 13.

  Here, FIG. 5 is an enlarged view showing a V portion of FIG. The adhesive layer 12 has a primer layer (first layer) 17 formed on the back surface of the front plate portion 14 and a binder layer (second layer) 18 formed so as to overlap the primer layer 17. The materials constituting the primer layer 17 and the binder layer 18 are different from each other. The bonding force between the primer layer 17 and the binder layer 18 is higher than the bonding force of the molded body 13 to the metal constituting the button cap 11. The primer layer 17 and the binder layer 18 are both transparent resin layers.

  In this example, an adhesive ink (first adhesive ink) that is urethanized by two-component isocyanate curing based on a vinyl chloride copolymer (copolymer of vinyl chloride and vinyl acetate) and a polyester resin as main components. The resin layer formed using the resin layer is a primer layer 17 and the vinyl chloride copolymer resin layer is a binder layer 18. In this example, the thickness of each of the primer layer 17 and the binder layer 18 is 10 μm or more.

  The molded body 13 is provided on the back surface of the button cap 11 in a state of covering the adhesive layer 12. Further, the molded body 13 is integrated with the button cap 11 in close contact with the button cap 11 and the adhesive layer 12 without a gap. Furthermore, the molded body 13 is molded such that a depression is formed on the back side of the button cap 11.

  As shown in FIG. 4, the molded body 13 protrudes into the display hole 16 from the main body portion 19 and the main body portion 19 that are molded along the back surfaces of the front plate portion 14 and the side plate portion 15. And an engagement portion 21 that protrudes from the main body portion 19 toward the inside of the operation button 5 and engages with the button unit 4.

  The fitting portion 20 is in close contact with the inner surface of the display hole 16 and the end surface of the adhesive layer 12 without a gap. The operation button 5 is attached to the button unit 4 when the engaging portion 21 engages with the button unit 4.

  The molded body 13 is made of a translucent resin (transparent or translucent resin). Thereby, the light passing through the position of the display hole 16 among the light illuminated from the light source 9 to the back surface of the operation button 5 reaches the landing side through the molded body 13. On the other hand, light passing through positions other than the display hole 16 out of the light illuminated from the light source 9 to the back surface of the operation button 5 is blocked by the button cap 11. In this example, the resin constituting the molded body 13 is polycarbonate (PC). The resin constituting the molded body 13 is not limited to polycarbonate, and may be, for example, acrylic resin (PMMA) or ABS resin (acrylonitrile / butadiene / styrene copolymer synthetic resin).

  Next, a method for manufacturing the operation button 5 will be described. When the operation button 5 is manufactured, a metallic button cap 11 is prepared in advance by drawing or bending. Thereafter, the adhesive layer 12 having the primer layer 17 and the binder layer 18 is formed on the back surface of the front plate portion 14 of the button cap 11 (adhesive layer forming step).

Thereafter, the first adhesive ink applied to the back surface of the front plate portion 14 is dried to form the primer layer 17 (first layer forming step).

  After the first layer forming step, a second bonding ink different from the first bonding ink is applied to the primer layer 17 in an overlapping manner. The application of the second adhesive ink to the primer layer 17 is performed by pressing a tampon impregnated with the second adhesive ink against the primer layer 17 in the same manner as the application of the first adhesive ink. Thereafter, the second adhesive ink applied over the primer layer 17 is dried to form the binder layer 18 (second layer forming step). In this way, the adhesive layer 12 is formed on the back surface of the front plate portion 14.

  After the adhesive layer forming step, insert molding is performed by injecting a predetermined resin into the mold for the button cap 11 having the adhesive layer 12 formed on the back surface of the front plate portion 14.

Thereby, the molded body 13 can be further prevented from coming off from the button cap 11, and the reliability of the strength of the operation button 5 can be further improved.

  In addition, since the molded body 13 having translucency is provided on the back surface of the button cap 11, the light from the light source 9 on the back side of the operation button 5 can be transmitted from the display hole 16 to the landing side. Thereby, the presence or absence of the registration of the call corresponding to each operation button 5 can be notified to the elevator user of the hall without impairing the design of the operation button 5.

  Further, since the operation button 5 is manufactured by integrating the molded body 13 with the button cap 11 through the adhesive layer 12 by insert molding after the adhesive layer 12 is provided on the back surface of the button cap 11, It can be manufactured easily. Moreover, since the button cap 11 can be reinforced with the molded body 13, the plate thickness of the button cap 11 can be reduced. Thereby, the precision of the bending process of the button cap 11 can be improved easily, and the designability of the button cap 11 can be improved.

  Further, the primer layer 17 is formed by applying the first adhesive ink to the back surface of the button cap 11, and the binder layer 18 is formed by applying the second adhesive ink on the primer layer 17. Thus, since the adhesive layer 12 is formed, the adhesive layer 12 can be easily provided on the back surface of the button cap 11. Further, the molded body 13 can be further prevented from coming off from the button cap 11.
