Description

[Detailed explanation of the idea] The present invention relates to a device for stopping an alarm clock from ringing.

Conventional alarm clock stop devices are integrally molded of plastic material as shown in Figs. A click leg plate 3 is provided in front of the column, and an operating piece 4 is provided vertically at the front end of the main body.

A protrusion 5 is formed on the outer surface of the lower end of the leg plate 3, and the switch body is attached to a central shaft (not shown) that is held between the support columns 2.

) can be rotated around the axis.

The shape of the operating piece 4 of the switch body 1 is a tongue-like piece with flat sides on both sides, and is opposed to the two elastic contact pieces 6, 6 for the switch, as shown in FIG. 6 when the switch body is lowered. In this way, the operating piece 4 is inserted between the contact pieces, and the operating piece is gripped by the elastic force of the contact pieces, cutting off the electricity and maintaining the no-squealing state.

Further, when the switch body 1 is lifted up, the contact pieces 6, 6 come into contact again due to their elastic effects and are energized to strike the bell, as shown in FIG.

When the switch body 1 stops ringing, the operation piece 4 is at the contact piece 6°6.
At the same time, the protrusion 5 of the leg plate 3 is locked at the lower end of the click locking plate 8 of the exterior frame T to continue stopping the sound (see FIG. 1).

Also, when the bell is struck, the switch body 1 rises and the protrusion 5 moves to the locking plate 8.
The bell is clicked into the concave groove 9 so that the striking of the bell can be continued (see Fig. 3).

However, the anti-squeal device having the above configuration and operation has a structure in which the protrusion 5 of the leg plate 3 overcomes the locking plate surface 8a between the groove 9 of the locking plate 8 and the lower surface of the locking plate, so the swinging range is If the condition shown in FIG. 8 is repeated without completely swinging the leg plate 3, the leg plate 3 will undergo permanent deformation due to creep fatigue, and the projection 5 will then become unable to click.

That is, as shown in FIG. 9, even if the operating piece 4 is inserted between the contact pieces 6, the operating piece is pushed up by the elastic action of the contact piece, and the squealing operation is not performed.

Also, due to variations in the product of the switch body 1, the contact piece 6
, 6 are out of alignment with the operation piece 4, the operation piece will be pushed up by the elastic pressure of the contact piece as described above, and the squealing function will be impaired.

Therefore, the present invention (i) aims to solve the drawbacks of the above-mentioned anti-squeal device, and is characterized by being equipped with a double locking mechanism.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the alarm clock ring stop device of the present invention shown in FIGS. 1 to 5 will be described.

An engaging portion such as a protrusion 41a is integrally formed outwardly at the tip of the operation piece 41 of the switch body 11, and two elastic contact pieces 61, 61a facing this operation piece are engaged with the protrusion 41a. The locking portion 61b is bent.

Note that the protrusion 41a provided on the operation piece 41 does not necessarily have to be oriented outward, and may be attached to the inside of the operation piece.

Further, as shown in FIG. 5, the operating piece 42 of the switch body 12
Projections may be provided protrudingly on both the inside and outside of the 42 ta t 42 a, and in this case, the contact pieces 62, 62a are provided with locking portions 62b, 62b that engage with the protrusions.

The other configurations are substantially the same as the conventional configurations shown in FIGS. 6-9.

In the anti-squeal device of the present invention constructed as described above, the operation piece of the switch body can click by engaging with the locking part of the contact piece, and the click action is disabled due to the conventional creep phenomenon. The operating piece and the contact piece click together, preventing the operating piece from being pushed up due to the elasticity of the contact piece as in the past, ensuring a sound-stopping operation, and the extremely simple structure has practical effects. is big.
