BACKGROUND OF THE INVENTION
The present invention relates to a wall-hanging structure for a wall-hanging device in which a wall-mounted device is provided with a dharma hole for wall-mounting and attached to the wall.
[0002]
[Prior art]
Conventionally, two Dharma holes for wall hanging are provided in the wall hanging device by an injection molding method or the like, and the wall hanging device is attached to the wall by being hooked on two screws embedded in the wall. When a dharma hole is provided in a wall-hanging device, an inner wall is provided on the whole so that the inside of the device cannot be seen from the outside by a dharma hole to prevent entry of foreign matter. Also, since a certain distance between the two dharma holes is necessary, a cavity having a distance greater than the distance between the two dharma holes must be formed between the inner wall and the outer wall. Foreign matter such as screws from the dharma hole is once dropped into the hollow housing so as not to get caught anywhere, and discharged to the outside, so this hollow portion is a housing considering the size of the foreign matter Had to be a long and large space in the outer wall.
[0003]
[Problems to be solved by the invention]
In a wall-hanging device subject to design restrictions, or from the ease of injection molding, there has been a demand for a structure that reduces the volume of the cavity as described above, which has nothing to do with the original function.

[0007]
First, a charger 8 for a conventional cordless telephone cordless handset will be described with reference to FIG. FIG. 6 (1) shows a central cross-sectional view of the charger 8 in which portions not related to the present invention are omitted. FIG. 6 (2) shows a rear view of the charger 8. When the charger is attached to the wall, screws 93 and 94 are attached to the wall in advance. Next, the charger is pressed against the wall so that the heads of the screws 93 and 94 are inserted into the Dalma holes 91 and 92 provided on the back surface of the charger, respectively, and further pulled downward, the screw body becomes the Dalma hole 91 and The charger is fixed to the wall by engaging the head of 92.
[0008]
In general wall-mounted devices, the screws are often pulled together when the device is removed from the wall. In the conventional charger 8 described here, the screws 93 and 94 are pulled out from the wall by the charger. The screws 93 and 94 enter the cavity 90 of the charger 8 and fall further downward. In this way, screws or other foreign substances are prevented from entering the charger. However, providing the hollow portion 90 to the extent that the screw is not caught inside the charger is limited in size and design if it is a small device.
[0009]
The structure of the charger of the present invention will be described below.
First, the configuration of the lower cover will be described. 2 and 1, the lower cover 2 is provided with a dharma hole 21 on the upper side from the center of the back surface and a dharma hole 22 on the lower end of the back surface. As shown in FIGS. 1 and 2, the lower part of the dharma hole 21 is a recess 23 for introducing a screw head. The lower part of the Dharma hole 22 is cut out, the inside is surrounded by the inner wall 44, and is shielded from the inside of the charger.
In FIG. 4, in the lower cover, the recessed outer wall combined lower rib 4 that constitutes the recessed portion 23 is a parallel wall portion 41 that is substantially parallel to the rear surface of the lower cover, and is perpendicular to the rear surface. And two vertical wall portions 43. The central portion of the upper end of the parallel wall portion 41 is a convex portion.
[0010]
The lower end of the upper rib 3 of the upper cover 1 has a shape that matches the upper end of the lower rib 4 that also serves as a concave outer wall of the lower cover 2. That is, the parallel plate portion 31 of the upper rib that is substantially parallel to the back surface of the upper cover and the two vertical plate portions 33 of the upper rib that are perpendicular to the back surface are substantially parallel to the back surface of the lower cover. This is a structure that engages with the parallel wall portion 41 of the lower rib serving as a concave outer wall and the vertical wall portion 43 of the lower rib serving as a concave outer wall that is perpendicular to the rear surface.
Further, the lower end of the parallel plate portion 31 of the upper cover is a recessed portion 32 so as to fit into the convex portion 42 of the parallel wall portion 41 of the lower cover.
In this way, when the upper cover 1 and the lower cover 2 are overlapped, the two vertical plate portions 33 of the upper rib are in contact with the inner side of the lower cover rear wall, so The hole portion penetrating into the inside is completely closed by the upper rib of the upper cover 1.
[0011]
Moreover, as shown in FIG. 1, the inside of the dharma hole 22 in the lower cover 2 is surrounded by the inner wall 44 and does not communicate with the inside of the charger.
[0012]
The upper cover 1 and the lower cover 2 are joined with tapping screws from the lower cover side at two places as shown in FIG.
When attaching to the wall, insert the charger's Dharma holes into the heads of the two wood screws attached to the wall in advance, and then place the charger slightly downward so that the head of the Dharma hole hits the screw body. Pull to complete the charger wall mounting.
[0013]
【The invention's effect】
As described above, the above configuration is adopted so that screws or dust that has been accidentally pulled out when the charger is pulled out from the wall will not enter the wall-mounted device from inside the dharma hole, thus reducing the space for wall mounting. In addition to gaining design freedom, injection molding can also be simplified.
