  Hereinafter, the best mode for carrying out the present invention will be described in detail with reference to the drawings.

  1 is an exploded perspective view of a bathroom interphone (secondary master unit) that is a waterproof device, FIG. 2 is a plan view of a case body 10, and FIG. 3B is an assembled cross-sectional view corresponding to the line AA in FIG. It is.

  The case body 10 made of synthetic resin includes a lower case 11 and an upper case 12, and a circuit board 24 on which a total of six switches 13 are mounted is housed in these cases 11 and 12.

  In the upper surface 12a of the upper case 12, switch openings 12b facing the switches 13 are formed.

  As shown in detail in FIG. 2, the switch opening 12b is notched on the three sides of the upper surface 12a in a substantially Ω shape and left as one hinge portion 12c. A movable hinge piece 12d is integrally formed.

  The hinge piece 12d having the same shape as the hinge piece 12d is formed at a total of four positions on the upper surface 12a in correspondence with positions of elliptical push buttons 14 to 17 described later.

  Further, as the switch opening 12b, the three sides of the upper surface 12a are cut out in a substantially U shape and one side is left as a hinge portion 12c so as to correspond to the position of a small circular push button 18 to be described later. The hinge piece 12e that can swing up and down by the elasticity of the synthetic resin is integrally formed.

  Further, referring to FIG. 3 (a), as the switch opening 12b, three sides of the upper surface 12a are cut out in a substantially semicircular shape corresponding to the position of a relatively large circular push button 19 described later. By leaving one side as the hinge portion (first hinge portion) 12c, the first hinge piece portion 12f that can swing up and down by the elasticity of the synthetic resin is integrally formed on the inner side (pressed surface) of the cut.

  The hinge piece portion (first hinge piece portion) 12f is further cut out in a substantially semicircular shape on the three sides of the hinge piece portion (first hinge piece portion) 12f, and the hinge portion (first hinge portion) 12c. By leaving one of the opposite sides as the second hinge portion 12c ′, the second hinge piece portion 12f ′ that can be swung up and down by the elasticity of the synthetic resin is integrally formed inside the cut. Although the second hinge portion 12c ′ is set at a position of 180 degrees with respect to the hinge piece portion (first hinge portion) 12c, it can be set at a range position of about 90 degrees.

  The second hinge piece 12f ′ is formed with a circular light transmitting hole 12g that faces the LED light emitting unit 20 of the circuit board 24 and transmits the light from the LED light emitting unit 20.

  A speaker opening 12 h is formed in the upper surface 12 a of the upper case 12.

  A cover body 22 is attached to the upper surface 12 a of the upper case 12 via a waterproof sheet material 21, and push buttons 14 to 19 facing the button openings 22 a to 22 f of the cover body 22 are formed on the upper surface of the waterproof sheet material 21. It is stuck and fixed. In addition, 22g is an opening for speakers.

  As shown in detail in FIG. 3B, a second hinge is provided on the back surface (surface on the upper surface 12a side of the upper case 12) of the waterproof sheet material 21 corresponding to the position of the relatively large circular push button 19. A ring-shaped escape recess 21a is formed so as to be able to contact only the piece 12f 'and escape so as not to contact the first hinge piece 12f.

  In the bathroom interphone (secondary master) push button structure as described above, the hinge is provided in the switch opening 12b on the upper surface 12a of the upper case 12 corresponding to the position of the relatively large circular push button 19. The first hinge piece portion 12f that can swing up and down is formed by the portion (first hinge portion) 12c, and the second hinge portion 12c ′ is moved up and down inside the first hinge piece portion 12f (the pressed surface). A movable second hinge piece 12 f ′ is formed, and the second hinge piece 12 f ′ is pushed by the push button 19.

  When the push button 19 is relatively large, when the vicinity of the center portion of the push button 19 is pressed (see the arrow b in FIG. 3B), the second hinge portion 12c ′ is mainly used as a fulcrum. The two hinge pieces 12f ′ swing downward (see FIG. 3C).

  When the vicinity of the peripheral portion of the push button 19 is pressed (see arrow c in FIG. 3B), the first hinge piece 12f swings downward with the hinge portion (first hinge portion) 12c as a fulcrum. Therefore, since the distance from the fulcrum does not fluctuate extremely, the push stroke is unlikely to be different, and a good operation feeling can be obtained.

  Further, since the light transmitting hole portion 12g of the LED light emitting portion 20 mounted on the circuit board 24 is formed in the vicinity of the second hinge portion 12c ′ of the second hinge piece portion 12f ′, the light transmitting property of the push button 19 is formed. The symbol part 19a (refer FIG. 1) can be made to shine with LED. In this case, the upper case 12 and the waterproof sheet material 21 are preferably transparent or translucent material. If the material has excellent translucency, the translucent hole 12g is formed as shown in FIG. There is no need to form it.
