Description

Description: TECHNICAL FIELD The present invention relates to a desk-top wall-mounted telephone including a handset and a main body.

(Prior Art) A conventional desk-top wall-mounted telephone (hereinafter referred to as a telephone) will be described with reference to FIGS. 3 to 5.

FIG. 3 is a cross-sectional view of an essential part showing a state in which a conventional telephone is used for desk use, and the telephone is composed of a handset 1 including a transmitter and a receiver, and a main body 2 on which the handset 1 is placed. The handset 1 has an engaging recess 1b formed on the inner outer wall of the handset portion 1a, which is required when it is used for wall hanging. The body 2 is formed with a mounting recess 2a into which the handset portion 1a of the handset 1 is fitted, and is always rotated counterclockwise by a spring device (not shown) from a square hole 2b provided on the inner side thereof. Hook switch 3 with protruding switch button 3a
Is provided. The hook switch 3 is
It is mounted on a printed circuit board 4 built in the main body 2.
Further, mounting recesses 2c are formed at positions corresponding to the engaging recesses 1b of the handset 1 so as to be aligned with the mounting recesses 2a.

The operation when the telephone configured as described above is used for desk use will be described. Handset 1 handset
When it is placed on the main body 2 so that 1a fits into the mounting recess 2a, the switch button 3a is pushed down, and the hook switch 3 becomes OF.
When the handset 1 is lifted, the switch button 3a goes up, and the hook switch 3
Is turned on and you can talk.

FIG. 4 is a cross-sectional view of an essential part showing a case where the telephone is used for hanging on a wall. The difference from the desk-top use shown in FIG.
That is, the supporting piece 5 is fixed to the mounting recess 2c with the screw 6.

The operation when the telephone having such a structure is mounted on a wall and used will be described.

So that the engaging recess 1b is locked to the supporting piece 5 of the main body 2,
When the handset 1 is hung on the main body 2, the handset unit 1a pushes the switch button 3a, the hook switch 3 is turned off, and the call is disconnected. When the handset 1 is detached, the switch button 3a is lifted by the spring device, and the call state is established.

(Problems to be Solved by the Invention) However, in the above-mentioned configuration, when the handset 1 is used for wall hanging, as shown in FIG.
Since the handset 1 is lowered from above along the main body 2 when it is hung on, the height cannot be increased so that the outer bank 2d of the mounting recess 2a does not become an obstacle. Therefore, when used as a tabletop, as shown in FIG. 5, when the handset 1 is placed on the main body 2, the handset 1 easily comes off, and even if the hook switch 3 is in the OFF hook state, it is not noticed.
There was a problem that I was in a call.

The present invention solves the above problems and provides a desk-top telephone that is easy to use and has a handset that is not displaced when used as a desk-top.

(Means for Solving the Problems) In order to solve the above-mentioned problems, the present invention provides an engaging projection that protrudes from a lower surface of the main body facing the mounting recess, and a lower end of the mounting recess when mounted on the main body. A guide part for hooking the outer bank and projecting an inclined surface bulging inward with a roundness from the inside of the mounting recess, and an arm part having an engagement hole for fitting with the engagement protrusion when mounted on the main body. And an outer wall adapter that can be detached from the main body by elastically deforming the arm so that the engaging hole is disengaged from the above-mentioned engaging protrusion, and when used as a tabletop, the outer wall adapter When attached to the main body and used for wall hangings, do not attach the outer wall adapter to the main body.

(Operation) With the above configuration, when used as a tabletop, the handset is guided by the inclined surface as the inclined surface projects from the mounting recess by the guide portion of the attached outer wall adapter. Can be easily placed on the mounting dent of the main body, and even if the handset is misplaced, it can be checked at a glance by placing it on the guide part and preventing the handset from hanging halfway it can. Also, when used for wall hangings, the outer wall adapter can be removed, so there is no obstacle when hanging the handset on the main body.

(Embodiment) An embodiment of the present invention will be described with reference to FIGS. 1 and 2.

FIG. 1 is a cross-sectional view of essential parts showing a state in which the desk-top wall-mounted telephone according to the present invention is used for desk-top use. The same components as those of the conventional example shown in FIG. 3 are designated by the same reference numerals and the description thereof will be omitted.

In the figure, the difference between the telephone according to the present invention and the conventional example is that the outer wall adapter 7 which can be freely attached and detached by elastic deformation is mounted on the outer bank 2d of the main body 2. Others are the same as the conventional example shown in FIG.

Two engaging projections 2e for attaching the outer wall adapter 7 are formed on the lower surface of the main body 2 facing the mounting recess 2a.

The outer wall adapter 7 attached to the outer bank portion 2d of the main body has a half-moon shaped guide portion 7a having a circular arc shape whose lower end is along the outer bank portion 2d of the main body 2 and having an inclined surface which is rounded and bulges inward.
At the center of the back surface thereof, two engaging holes 7b that fit into the engaging protrusions 2e of the main body 2 are formed, and an elastic C-shaped arm portion is formed.
It is composed of 7c and.

In order to attach the outer wall adapter 7 having such a configuration to the main body 2, as shown in FIG. 1, the lower end of the guide portion 7a is recessed for mounting.
When it is hung on the outer bank 2d of 2a and pushed in by rotating the arm 7c counterclockwise, the arm 7c elastically deforms and gets over the engaging protrusion 2e, and the engaging hole 7b fits into the engaging protrusion 2e. Then, it is fixed as shown in FIG.

The operation when the telephone having such a configuration is used for desktop will be described with reference to FIGS. 2 (a) and 2 (b).

When the handset 1 is placed on the main body 2, as shown in FIG. 2 (a), even if the position of the handset portion 1a does not coincide with the mounting recess 2a, it is guided by the guide portion 7a of the outer wall adapter 7. Then, the mounting recess 2a is accommodated, and the switch button 3a is pushed in to disconnect the call.

Further, when the handset portion 1a is placed on the guide portion 7a, the handset 1 is raised from the main body 2 so that the half-hanged state of the handset 1 can be easily visually recognized.

When the telephone is used for hanging on a wall, when the tip of the arm portion 7c of the outer wall adapter 7 mounted on the main body 2 is raised, the engaging hole 7b is disengaged from the engaging protrusion 2e of the main body and can be removed. Furthermore, if the mounting recess 5 is attached to the supporting piece 5,
Like the conventional example shown in FIG. 4, it can be used by hanging it on the wall surface.

In this embodiment, the outer wall adapter 2 is used to attach the outer wall adapter 2d, but it goes without saying that a separate engagement protrusion may be provided.

(Effects of the Invention) As described above, according to the present invention, when used as a tabletop, an outer wall adapter is attached, and the inclined surface of the guide portion is projected from the inside of the mounting recess, whereby the handset is set. Even if they are placed out of position, the slanted surface of the guide part will place them in the mounting dents and turn off the hook switch. When the handset rests on the guide of the outer wall adapter, it can be confirmed at a glance that the handset was not placed correctly. Further, when used for wall hangings, the outer wall adapter can be easily removed, and it does not prevent the wall hangings from being used.
