Description

[Detailed Description of the Invention] The present invention relates to a structure for preventing the hook button of a telephone from falling off.

FIG. 1 is a partial sectional view of a conventional hook button falling-off prevention structure, and FIG. 2 is a perspective view of the hook button. In FIG. 1, 1 is a hook button, 2 is a claw of the hook button 1, 3 is a cover body that holds the hook button 1, 3' is a guide hole for the hook button 1 formed in the cover body 3, and 4 is a cover body 3. A clasp 5 is fixed to support the hook button 1, and a retaining screw 5 fastens the cover body 3 and the clasp 4. The hook button 1 is inserted into the guide hole 3' of the cover body 3, and the claw 2 of the hook button hits the cover body 3, and the hook 4 is pushed into the cover body 3 by narrowing the claw 2 with the cover body 3 at a constant distance. Fix it with screw 5,
The stroke of the hook button 1 is defined by a cover body 3 and a clasp 4. Therefore, the number of parts increases, and when the hook button is mounted on the housing, the housing 3 has to be held upside down before tightening, and this has many disadvantages.

In order to eliminate these drawbacks, the present invention provides a flange-like projection on the top surface of the hook button that extends perpendicular to the movement of the hook button, and a tapered claw with elasticity at the lower end of the side surface of the hook button. , which has a structure in which the body is narrowed, will be explained in detail below.

FIG. 3 is a partial sectional view showing an embodiment of the present invention;
FIG. 4 is a perspective view of the hook button. Reference numeral 21 indicates a hook button, and 22 indicates a collar-shaped projection formed on the upper surface of the hook button 21 and extending in a direction perpendicular to the operation of the hook button 21, that is, extending toward the upper surface of the hook button 21. , 23, 23' are tapered claws formed at the lower ends of both sides of the hook button 21, one or both of which have elasticity, 24 is a cover body for holding the hook button 21, and 25
The body 24 is for inserting the hook button 21.
This is a hole for attaching a hook button. If one claw 23 of the hook button 21 does not have elasticity, the hook button fitting hole 25 of the cover body 24
First, the claw 23 of the hook button 21 is inserted, and then the elastic claw 23' of the hook button 21 is deformed and inserted into the hook button insertion hole 25. In this state, the claws 23, 23' and the protrusion 2
2 and tightly fit the cover body 24 in the hook button fitting hole 25 portion with a predetermined interval. The inserted hook button 21 is prevented from falling by the brim-shaped protrusion 22 on the top surface of the hook button, and the claws 23, 2
3' prevents it from coming off. And the body 24
Narrow the protrusion 22 and claw 23 of the hook button 21,
23'.

Also, both claws 23, 2 of the hook button 21
3' is made elastic, the elastic claws 23, 23' of the hook button 21 are inserted into the hook button fitting hole 25 of the cover body 24 while being deformed at the same time, and restored after insertion. Hereinafter, the flange-shaped projection 22 serves as a stopper, and the claws 23, 23' serve as a stopper.The definition of the operating range is the same as in the case where one of the claws does not have elasticity.

As explained above, in this embodiment, the hook button is provided with a flange-like protrusion to prevent it from falling and a resilient claw, and the resilient claw of the hook button is provided in the hook button insertion hole formed in the cover body. Once inserted, the hook button can be prevented from falling off from the body due to the collar-like protrusion and claws that prevent it from falling. Therefore, there is no need for a fastener to support the hook button or a screw for fastening, and there is an advantage that the hook button can be mounted from the surface of the body.

The present invention uses resilient plastic or the like for the hook button, so the hook button can be easily attached by simply drilling a hole in the cover body, and it provides a hook button that is extremely easy to assemble without using any fastening parts. available for phones.
