Description

[Detailed description of the invention] In recent years, with the development of electronic components, telephones are becoming smaller and lighter. Furthermore, telephones, which were conventionally produced separately into desk-top and wall-mounted types, are now being used as dual-purpose telephones in consideration of productivity and economy.

When changing from tabletop use to wall-mounted use, at least the following parts must be prepared as additional supplies. That is, 1. Handset/receiver holder for preventing the handset from falling off. 2. Mounting bracket for attaching the telephone to a wall surface. The present invention relates to the mounting structure of the mounting bracket described in 2 and the telephone housing.

The conventional mounting structure consists of a mounting bracket 1 and an auxiliary mounting bracket 2, as shown in Fig. 1. When installing, first fix the mounting bracket 1 to the wall surface, and then attach the protrusion 3 provided at the upper end of the mounting bracket 1. The phone is inserted into the mounting hole provided in the lower casing of the phone, the phone casing is pulled down in the direction of arrow A, and the mounting bracket 1 and the auxiliary mounting bracket 2 are fastened and fixed. This structure requires a large number of parts and requires complicated installation work.

FIG. 2 shows that the mounting bracket 5 is fixed to the wall, the protrusion 6 provided on the mounting bracket 5 is inserted into the lower phone housing 8, and the lower phone housing 8 is pulled down in the direction of arrow A. Horizontal protrusion 7 provided on the upper end of the side plate of
This is a structure in which the phone housing 8 is fixed by bending the phone housing 8 toward the phone housing. This structure requires a special tool to bend the horizontal protrusion 7 inward, and not only is the workability poor, but the tool may also damage the telephone during the work.

Both the mounting aid 2 shown in FIG. 1 and the horizontal protrusion 7 shown in FIG. 2 are used to prevent the phone from falling off when a force is accidentally applied in the direction opposite to the direction of arrow A when the phone is in use.

The present invention has been proposed in view of the above-mentioned points, and aims to prevent the attached telephone from rattling and falling off by a simple configuration of the bottom surface of the lower housing of the telephone and the mounting bracket.

An embodiment of the present invention will be described below with reference to the drawings.

As shown in FIG. 3, the mounting bracket 9 is composed of a back plate 9-1 and side plates 10 bent at right angles from both ends of the back plate 9-1. A hole 13 is provided for attaching the phone to a wall, and locking portions 11 are provided at the upper and lower sides of the side plate 10 for locking the phone case, respectively, and locking portions 11 are provided at approximately the center of the upper and lower sides of the side plate 10. A cutout-like recess 12 is provided.

Next, referring to the synthetic resin molded phone case, as shown in FIG.
A slight protrusion 16 having an inclined surface is provided at a position facing the notch recess 12 when the mounting bracket 9 is fitted and locked to the bottom surface 14 of the lower housing of the telephone.

Next, the installation of the mounting bracket 9 will be explained.
As shown in FIG. 5, fix the mounting bracket 9 to the wall using the hole 13 of the mounting bracket 9, insert the locking part 11 into the insertion hole 15 of the lower housing 14, and pull down the lower housing 14 in the direction of arrow A. . At this time, as shown in FIG. 6, the side plate 10-1 in the vicinity of the notch-like recess 12 presses the inclined surface 16a of the slight protrusion 16, and the lower casing that is pressed is indicated by the dotted line in the figure. It becomes inwardly bent due to elastic deformation.

The side plate 10-1, which moves upward while pressing the inclined surface 16a, climbs over the protrusion 16 and reaches the protrusion 1.
6, the protrusion 16 fits into the notch-shaped recess 12 and is locked.

When the fitted and locked state is reached, even if the lower housing 14 is accidentally pushed up in the direction opposite to the direction of arrow A, the vertical surface 16b of the protrusion 16 cannot easily go over the side plate 10-1, and the attached telephone falls off. There's nothing to do.

As mentioned above, the mounting structure of the wall-mounted telephone according to the present invention allows the telephone user to easily change the installation in a short time without using any special tools, and is also highly economical. It is effective.
