Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a structure of an elevator button, and more particularly to a structure of an elevator button that is strong against a strong pressing operation and is less likely to generate noise.

[0002]

[Prior art]

 A general elevator control panel has a structure in which a plurality of floor buttons 11 are provided side by side on a panel 10, as shown in FIG. As shown in FIGS. 3, 4, and 5, the conventional button includes a mounting frame 12, a button body 13, a spring 14, and a circuit board 15. The touch switch 20 having the structure shown in FIG. 4 is mounted on the circuit board 15. The touch switch 20 has a contact 23 and an operation knob 22. When the button body 13 is pushed with a finger, the pushing convex portion 21 pushes the operation knob 22 of the touch switch 20, the contact 23 is closed, and when the finger is released, the button body 13 is returned by the spring 14.

[0003]

[Problems to be solved by the invention]

 However, in the case of the conventional button, when the button body 13 is strongly pressed, the force of the strong pressing may be transmitted to the touch switch 20 at once and the touch switch 20 may be damaged. Further, when the button body 13 is returned by the spring 14 by releasing the finger, the frame-shaped surface around the button body 13 may collide with the inner surface of the mounting frame 12, and unnecessary sound may be generated. There was

Therefore, an object of the present invention is to provide an elevator button structure that solves the above problems.

[0005]

[Means for Solving the Problems]

 The invention of claim 1 has a mounting frame, a button body, a return spring, and a circuit board, and at the bottom side of the button body, four small convex bodies of appropriate height are provided, and the button body is provided. It is configured such that small convex bodies are uniformly arranged and provided on four planes outside the main body.

According to the second aspect of the present invention, a point Braille sentence for the blind is provided directly on the surface of the button body.

[0007]

[Embodiment of the invention]

 As shown in FIG. 1, the structure of the improved elevator button comprises a mounting frame 30, a button body 31, a return spring 32, and a circuit board 33. On the bottom side of the button body 31, four small convex bodies 301 of appropriate height are formed near each corner.

Further, on the four outer planes of the button body 31, small convex bodies 302 are uniformly arranged, two on each plane. Even when the button body 31 is strongly pushed and receives a strong and large pressure, the small convex body 301 on the bottom side of the button body 31 first comes into contact with the circuit board 33, so that the circuit board 33. An appropriate buffer space is formed between the bottom surface 303 of the button body 31 and the bottom surface 303. Therefore, the bottom surface of the button body 31 will not be pushed at once and the touch switch 20 of the circuit board 33 will not be damaged. Therefore, the ability to withstand impact is greatly improved compared to the conventional one, and the service life is extended.

When the fingertip is released from the button body 31 and the button body 31 is returned by the force of the spring 32, the small convex bodies 302 on the four outer planes of the button body 31 come into contact with the inner surface of the mounting frame 30. Therefore, the button body 31 and the mounting frame 30 are in point contact with each other, so that noise and noise are significantly reduced as compared with the case where the surfaces contact each other. Therefore, the structure of the improved elevator button according to the present invention has higher quality than the conventional one.

In addition, a point Braille sentence 304 for the blind is formed directly on the surface of the button body 31. Therefore, a blind person can know the number of floors by touching the surface of the button body 31 and will not accidentally push the button body on a floor different from the target floor. Therefore, the improved elevator button structure according to the present invention is more convenient than the conventional one when it is used by a physically handicapped person.

The surface of the button body 31 is made of stainless steel. Therefore, the structure of the improved elevator button is more durable and can withstand high temperatures than ever before. Further, the circuit board 33 is covered with a waterproof glue material. Therefore, the structure of the improved elevator button according to the present invention has a higher insulation effect and higher waterproofness than the conventional one.

[0012]

[Effect of the invention]

 As described above, according to the first aspect of the invention, since the four small convex bodies of appropriate height are provided on the bottom side of the button body, the four small convex bodies of appropriate height are buffered. By acting so, even if it is strongly pressed, it becomes difficult for the impact to be transmitted, and it is possible to prevent damage to the switches and the like.

Further, since the small protrusions are uniformly arranged and provided on the four flat surfaces on the outside of the button body, when the button body is restored by the force of the spring, the button body and the mounting frame are attached. The contact with the point is a point contact, which produces a good silencing effect and prevents noise and noise. According to the second aspect of the present invention, the point body for the blind is provided directly on the surface of the button body. Therefore, the blind person can also know the floor number by touching the surface of the button body, and the wrong Therefore, the button body on the floor different from the intended floor will not be pressed. Therefore, when it is used by a physically handicapped person, it is more convenient than before.
