JP4690078B2 - Waterproof / dustproof cover for elevator pushbutton and elevator pushbutton device using the same - Google Patents

Description

  The present invention relates to a waterproof / dustproof cover for an elevator push button installed in a place where rainwater or the like easily enters, and an elevator push button device using the same.

As a conventional elevator push button device, for example, a structure in which silicon rubber is sandwiched between the face plate and the push button portion or a structure in which a transparent seal is bonded to the surface of the face plate for waterproofing and dustproofing. Etc.
In addition, as a prior art other than the above, a protective cover part composed of a waterproof / dustproof outer edge body and a transparent protective filter is stuck on the face plate, and a gap filling member is provided between the transparent protective film and the push button part. What was arranged is known (for example, refer to patent documents 1).

Japanese Patent Laid-Open No. 9-315710

The conventional elevator push button device has a problem that the silicone rubber discolors due to aging and the letters on the button become invisible. In addition, there is a problem that the adhesive layer of the transparent seal can be seen and the design property is poor. In addition, in the case where the filter is composed of a transparent protective filter, the filter protrudes to the face plate side and has poor design, and the filter mounting and replacement work is troublesome.
Further, in the above-described conventional apparatus, it is difficult to inexpensively configure a convex character button on the button for all visually impaired persons to touch and discriminate characters. In addition, since the pressing force of the button changes depending on the elasticity of silicon rubber, a transparent seal, and a transparent protective filter, there is a problem that it is difficult to press.

  The present invention has been made to solve the above-described problems. It adds an operational feeling without impairing the design, facilitates the mounting and replacement work on the face plate, and can cope with visually impaired persons. An object is to provide a waterproof / dustproof cover for an elevator push button and an elevator push button device using the same.

The waterproof / dust-proof cover for an elevator pushbutton according to the present invention is provided so as to cover the front face of the button, is made of a flexible resin, has a cross-sectional dome shape with a convex surface side, and has a click feeling that is recessed when pressed. The operation film having a flat edge on the peripheral edge portion, the printed layer on which the characters are printed, the central portion being opened, and the operation film on the front peripheral edge A frame-like base plate on which the peripheral flat portion of the printing layer and the peripheral flat portion of the printed layer are overlapped with each other, and engaging claws that are detachably attached to the face plate are provided on the upper and lower portions of the back surface of the base plate. A positioning boss is provided in the upper and lower portions of the back surface of the back plate and on the outer side of the engaging claw so as to be inserted into the through hole of the face plate and to position the button .

  The elevator pushbutton device according to the present invention is such that the elevator pushbutton waterproof / dustproof cover constructed as described above is mounted on the periphery of each opening of the face plate so as to cover the front of each button. .

  According to the present invention, it is possible to provide an elevator pushbutton waterproof / dustproof cover and an elevator pushbutton device using the same, to which an operational feeling is added without impairing the design.

Embodiment 1.
