Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a push button operating device for electric equipment used for push button chimes and the like.

[0002]

2. Description of the Related Art As a push button operation device for conventional electric equipment,
For example, taking a push button chime as an example, the products shown in FIGS. 16 and 17 are commercialized. The push button operating device a of this electric device is a box-shaped outer frame cover body c having a push button opening window b.
Further, the push button handle f having the mounting portion e extended is combined with the push operation portion d so that the push operation portion d of the push button handle f is exposed from the push button opening window b of the outer frame cover c. Further, the attachment portion e of the push button handle f is hollowed out at its central portion in order to facilitate elastic deformation at the time of pressing, and the hollowed-out portion g is provided with a pair of left and right protruding downwards on the inner surface of the outer frame cover body c. Of the outer frame cover body c in the hollowed-out portion g, and the inward and horizontal directions are regulated in order to regulate the movement range of the pair of left and right protrusions h, h. A pair of left and right locking projections i, i are formed.

Further, between the push button opening window b of the outer frame cover body c and the push operating portion d of the push button handle f fitted in the push button opening window b, the push operation of the push operating portion d is made smooth. A small gap j for forming is formed in the periphery. Further, a rod-shaped projection m is provided so as to project outward from the inner surface of the outer frame cover body c. The rod-shaped projection m penetrates the push button handle f in the assembled state, and is further attached with the push button handle f facing the outer frame cover body c. An elastic spring (not shown) for biasing is interposed, and a bar-shaped protrusion m
A circular collar body n for pressing a spring is fitted to the tip of the.

The operation of the push-button operating device a of the electric device having the above-mentioned structure will be described. When the push-operating portion d of the push-button handle f is pushed, the push-operating portion d of the push-button handle f resists the urging force of the elastic spring. With the tip of the push button handle f serving as a fulcrum, the contact spring p attached to the back surface of the push operation portion d of the push button handle f moves downward, that is, when the contact spring p moves downward, It contacts a connection terminal (not shown) of the base, which sends a signal to the indoor unit to ring the chime. When the push operation of the push operation portion d of the push button handle f is released, the urging force of the elastic spring is released. Then, the push button handle f returns to the state before the push operation.

[0005]

However, in the conventional structure, the central portion of the mounting portion e of the push button handle f is hollowed out, and the push button opening window b of the outer frame cover c and the push operation portion of the push button handle f are removed. Since a small gap j is formed between the push button handle f and the push operation portion d,
The pushing force is not evenly applied to the pushing operation portion d, and the push button handle f is tilted, so that the pushing amount of the contact spring p changes. Therefore, there is a problem that the operation feeling is bad and contact failure of the contact spring p may occur due to catching on the edge of the opening window b when the pressing operation portion d is pressed.

The present invention has been proposed in view of the above-mentioned problems of the prior art, and has a good operation feeling when a push button handle is pressed, and elastically deforms the push operation portion uniformly. It is an object of the present invention to provide a push button operation device for an electric device, which can be stably pressed without being caught by the contact and causing contact failure.

It has a shape in which the part is cut out in the longitudinal direction, and this cut out part is an elongated spring piece 4d.
Is formed.

Further, since the tip of the other connecting terminal 4a is located below the contact 4b, when the push operation portion 3a of the push button handle 3 is pushed, it is provided at the tip of the contact spring 4c. The contact 4b comes into contact with the tip of the other connection terminal 4a and is turned on. In addition, the push operation portion 3a of the push button handle 3
A concave portion 3f having a circular shape in a plan view for pressing operation is formed on the to facilitate pressing operation with a finger.

On the other hand, a locking projection 2d is provided on the inner surface 2c of the side wall of the outer frame cover body 2 inwardly, and the corresponding portion of the locking projection 2d on the base 4 is continuous with the inclined surface 4f. Since the locking concave portion 4g is provided, by covering the outer frame cover body 2 on the base 4 and pushing it down,
After the locking projection 2d moves along the inclined surface 4f, it is fitted into the locking recess 4g so that the outer frame cover body 2 and the base 4 are connected and fixed.

According to such a structure, the push button handle 3
When the push operation portion 3a, which is the free end, is pushed with a finger, the push button handle 3 is deformed downward with the fixed tip portion 3c as a fulcrum, and at this time, the contact point connected to one of the connection terminals 4a. The spring 4c is pushed downward via the disc spring mechanism 5, and the contact 4b at the tip of the contact spring 4c comes into contact with the tip of the other connecting terminal 4a to be turned on and a chime is sounded, but the push button handle 3 is pushed. When you release your finger from the operating section 3a,
Due to the elastic restoring force of the tongue piece 3b, the contact spring 4c instantly returns to its original position and the contact 4b is turned off.
