Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wall-hanging device used for hanging a wall-hanging device such as an intercom or a telephone set on a wall in a fixed state.

[0002]

2. Description of the Related Art Conventionally, as a wall hanging device of this kind, a structure in which an engaging portion of a wall hanging device is engaged with an engaging claw of a wall hanging tool fixed to a wall, or as shown in FIG.
A configuration is known in which a fixing screw 53 is passed through a screw mounting hole 54 from the front of a case 52 of a wall hanging device 51 and is screwed into a screw hole of a wall hanging tool (not shown) fixed to a wall.

[0003]

However, in the former configuration of the above-mentioned conventional examples, the wall hanging device may easily come off the wall hanging device due to contact with other objects, vibration, etc., and may be damaged. On the other hand, in the latter configuration, the head of the fixing screw 53 is exposed on the surface of the case 52, so that the appearance is poor.

The present invention solves the above-mentioned conventional problems, and prevents the wall-hanging device from easily falling off the wall-hanging device to prevent damage due to dropping.
Another object of the present invention is to provide a wall hanging device for a wall hanging device in which the fixing screw is hidden behind the emergency push button device so that the appearance can be improved.

[0005]

In order to solve the above problems, the present invention is configured to fix a wall hanging device to a wall hanging device by a fixing screw at a position hidden behind the emergency push button device in a closed state. It was done.

As a result, it is possible to obtain a wall-hanging device in which damage caused by dropping the wall-hanging device is prevented and the appearance is improved.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The invention according to claim 1 of the present invention is such that when the emergency push button device that can be opened and closed is closed in the case of a wall-mounted device, it is hidden behind the emergency push button device. The formed screw mounting hole and the wall mounting tool that is fixed to the wall and can temporarily fix the wall mounting device, the screw hole formed at the position corresponding to the screw mounting hole, and the screw mounting hole to the screw. It is equipped with a fixing screw that is screwed into the hole so that the wall-mounted device does not easily come off from the wall-hanging tool unless the fixing screw is removed with a tool. The button device can be hidden behind the button device.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings. 1 to 3 show a wall hanging device of a wall hanging device according to an embodiment of the present invention.
FIG. 3 is a vertical cross-sectional view of the wall hanging device fixed to the wall hanging device, FIG. 2 is a perspective view of the wall hanging device, and FIGS. 3A and 3B are explanatory views of an operation of fixing the wall hanging device to the wall hanging device.

1 to 3, 1 is a wall hanging device such as an intercom and a telephone, 2 is a wall hanging device, 3 is a fixing screw for fixing the wall hanging device 1 to the wall hanging device 2, and 4 is a wall. The wall hangings 2 are made of sheet metal or synthetic resin molding. In the illustrated example, it is made of sheet metal, engaging claws 5 project from the front sides of the four corners, screw mounting holes (not shown) for fixing with screws on the wall 4 are formed, and electrical components 6 are mounted on the front side. Has been done. In the wall-mounted device 1, a case 7 is composed of an upper case 8 and a lower case 9, and an engaging portion (not shown) composed of a hole, a recess or the like capable of engaging with the engaging claw 5 is provided on the back side of the lower case 9. An electric component (not shown) such as a substrate 10 is built in the case 7, and an emergency push button device 13 including an emergency push button 11 and an emergency push button cover 12 is openably supported on the front side. There is. Then, after the emergency push button 11 is pushed, it is opened to release it as shown in FIG. 1 and closed to return the emergency push button 11 to its original position.

In the case 7 of the wall-mounted device 1, the emergency push button device 13 is hidden behind the emergency push button device 13 in a closed state, and the emergency push button device 13 is exposed in the opened state with a screw mounting hole. 14 is formed. A fixing portion 15 is formed on the wall hangings 2 by cutting and raising or the like protruding toward the front side, and a screw hole 16 is formed in the fixing portion 15 so as to correspond to the screw mounting hole 14.

In the above-mentioned structure, the wall-mounted device 1 will be described below.
The wall hanging operation will be described. First, FIG. 1 and FIG.
As shown in (a), the wall hanging device 2 is fixed to the wall 4. Next, the electrical components of the wall-mounted device 1 are replaced by the electrical components 6 of the wall-mounted device 2.
Are electrically connected by means of plugs 17, 18 and sockets 19, 20. Next, the engaging portion of the wall hanging device 1 is attached to the wall hanging device 2
The wall-hanging device 1 is temporarily fixed to the wall-hanging tool 2 by engaging with the engaging claws 5 of. Thereafter, as shown in FIGS. 1 and 3B, with the emergency push button device 13 opened, the fixing screw 3 is screwed into the screw hole 15 of the wall hanging device 2 from the screw mounting hole 14 of the case 7 of the wall hanging device 1. By putting it in, the wall-mounted device 1 can be attached to the wall-mounted device 2
Can be fixed. Emergency button device 13 after fixing
Can be closed and set for normal use.

[0012]

As described above, according to the present invention, the wall-mounting device is fixed to the wall-hanging device by the fixing screw at a position hidden behind the emergency push button device in the closed state. It is possible to prevent the wall-mounted device from easily coming off the wall-mounted device to prevent damage due to dropping, and to hide the fixing screw in the back of the emergency push button device to improve the appearance.
