Abstract

PURPOSE:To simplify the mount structure of a hook level and the assembling by providing a wall part close to a U-shaped notch of a rib. CONSTITUTION:A flange 23d of a handset latch member 23 is screwed to a housing 20 by a screw 24 while a shaft 22b of a hook lever 22 is fitted to a notch 21a of a rib 21. When the member 23 is fixed, a rib 23c is engaged with a notch 22c and a wall part 23b is close to the U-shaped notch 21a of the rib 21 to be in press contact with a shaft 22b. Thus, the shaft 22b is escaped from the U-shaped notch 21a and limited by the wall 23b and the hook lever 22 is in the mount state. Moreover, a printed circuit board 31 with the hook switch 30 fitted thereto is screwed to the housing 20 by a screw 32 and the hook switch 30 is opposite to a main body 22a of the hook lever 22. Even when the hook lever 22 is strongly depressed, the hook switch 30 is not excessively depressed and the hook switch 30 is protected.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vertical telephone handset hanging mechanism, and more particularly to a hook lever mounting structure.

[0002]

2. Description of the Related Art FIG. 7 shows a conventional example.

In the figure, 1 is a telephone housing, 2 is a hook lever, 3 is a handset hanging member, and 4 is a hook switch.

The handset hanging member 3 is screwed and fixed by a screw 5.

The hook lever 2 has its shaft portion 2a fitted and supported in a U-shaped notch portion 6a of a rib 6 integral with the telephone housing 1.

The shaft portion 2a is restricted from coming out of the U-shaped notch portion 6a by a plate member 7 facing the opening of the U-shaped notch portion 6a.

The plate member 7 is fixed by screws 8 with screws.

Reference numeral 9 is a handset.

[0009]

Since the dedicated member (plate member 7) and the screw 8 are used to attach the hook lever 2, the handset hooking mechanism has a correspondingly increased number of parts, and the assembly work. Was troublesome.

Therefore, an object of the present invention is to provide a handset hooking mechanism for a vertically placed telephone which enables simplification of attachment of a hook lever.

[0011]

According to the invention of claim 1, a telephone housing is provided with a rib having a U-shaped notch for supporting a shaft portion of a hook lever, and a handset hanging member is attached to the telephone housing. The hook lever has a wall portion close to the U-shaped cutout when the hook lever is opened, and the shaft portion of the hook lever is prevented from coming out by the wall portion of the handset hook mounted on the telephone housing. The U of the rib
It is configured so as to be supported and attached in the letter-shaped notch.

[0012]

The handset hanging member having the wall portion according to the first aspect of the present invention, by attaching this member, acts so that the hook lever does not fall off.

[0013]

1 and 2 show a handset hanging mechanism for a vertical telephone according to an embodiment of the present invention.

In each drawing, 20 is a telephone housing,
A rib 21 is formed in the vicinity of the inside where the handset hanging member is attached. The rib 21 is formed with a U-shaped notch 21a.

Reference numeral 22 is a hook lever, and as shown in FIG. 3 together, a main body portion 22a and a shaft portion 22b on one end side thereof.
And a notch 22c.

Reference numeral 23 denotes a handset hanging member, which is shown in FIG.
As also shown in, the hanging portion 23a, the wall portion 23b,
It has a rib portion 23c and a screwing flange portion 23d.

The handset hooking member 23 has the flange portion 23d screwed and fixed to the housing 20 by the screw 24 in a state where the shaft portion 22b of the hook lever 22 is fitted in the notch 21a of the rib 21.

When the handset hanging member 23 is fixed, the rib portion 23c engages with the notch 22c, and as shown in FIG. 4, the wall portion 23b comes close to the U-shaped notch 21a of the rib 21 and the shaft 23c. It abuts the portion 22b.

As a result, the shaft portion 2 is formed by the wall portion 23b.
2b is restricted from coming out of the U-shaped notch 21a, and the hook lever 22 is attached.

Further, the printed board 31 to which the hook switch 30 is attached is screwed and fixed to the housing 20 with the screw 32, and the hook switch 30 faces the main body portion 22a of the hook lever 22.

The main body portion 22a projects from the opening 35, and the hanging portion 23a projects from the opening 36.

In the handset hooking mechanism having the above structure, the handset 40 is hooked on the hooking portion 23a while the hook lever 22 is pushed, as shown in FIG.
It is hung vertically.

The hook lever 22 is rotated around a shaft portion 22b which is restricted from coming out of the notch 22c by the wall portion 23b, and the hook switch 30 is pushed by the hook lever 22 to be switched to be turned on.

As shown in FIG. 6, the housing 20
Of these, stopper portions 37 that lock the main body portion 22a of the hook lever 22 and limit the rotation of the hook lever 22 more than a predetermined amount are formed on both sides of the opening 35.

Therefore, even when the hook lever 22 is strongly pushed, the hook switch 30 is not excessively pushed, and the hook switch 30 is protected.

[0026]

As described above, according to the first aspect of the present invention, a dedicated member and screw for attaching the hook lever can be eliminated, and the hook lever can be attached by the dedicated member and screw. In comparison, simplification of the configuration and simplification of the assembling work can be achieved.
