Can not be easily removed. Accordingly, it is possible to obtain the effects of preventing the fall and preventing theft.
Further, in the fourth aspect, since a plurality of magnets are used, not only the attractive force is increased, but also the position is reliably defined and the effect of being difficult to shift is obtained.
According to the fifth aspect of the present invention, since the wall surface to be attached is constituted by an attachment member having a projection shape substantially the same as the projection shape on the wall surface of the housing in the attached state, an effect of being inconspicuous is obtained.

Below, the attachment structure of the housing | casing concerning this invention is demonstrated in detail based on drawing which showed the embodiment.
FIG. 1 is a perspective view of a wireless network device having a housing mounting structure according to the present invention and a mounting member thereof.
In FIG.
Reference numeral 1 denotes a casing of the wireless network device, and 2 denotes an attachment member.
Four circular magnets 3, 3, 3, 3 are fixed to the back surface 11 of the housing 1 with screws. As shown in FIG. 2, a hole is formed in the center of the magnet 3, and a screw 4 is inserted into the hole, and the tip of the screw 4 is screwed into a screw hole formed in the back surface 11 of the housing 1. The magnet 3 is fixed to the back surface 11 of the housing 1.

  The casing 1 is additionally provided with a LAN connector and an antenna necessary for a wireless network device, and a necessary electronic circuit is provided inside.

The mounting member 2 is made of iron, which is a ferromagnetic material, and has a plurality of holes 21 through which screws for fixing to a wall or the like are passed.
Furthermore, in the attached state, four circular convex portions 5, 5, 5, 5 are formed so as to surround the four magnets 3, 3, 3, 3 of the housing 1, respectively. The circular portion 51 surrounded by the convex portions 5 has a flat surface in order to increase the attractive force with the magnets 3.
The four convex portions 5, 5, 5, 5 are formed at positions corresponding to the four magnets 3, 3, 3, 3 in the attached state.

As shown in FIG. 1, an upright piece 22 for screwing is provided on the upper edge of the mounting member 2, and a screwing hole 23 is provided in the upright piece 22.
On the other hand, a screw hole 12 is provided on the upper surface of the housing 1 at a position corresponding to the screw fixing hole 23 in the attached state.

Next, a case where the casing 1 having the above configuration is attached to a wall or the like will be described.
When the casing 1 is attached to a wall of a magnetic material such as an iron plate, it can be attached by being attracted by a magnet without the attachment member 2.
However, when mounting on a non-magnetic wall such as a plate wall or a concrete wall, mounting with a specified mounting position, or mounting so as not to be stolen, the hole 21 of the mounting member 2 is used first. Then, the mounting member 2 is fixed to the wall with screws.
Next, the positions of the four magnets 3, 3, 3, 3 of the housing 1 are matched with the positions of the four convex portions 5, 5, 5, 5 of the mounting member 2, so that each magnet It is adsorbed so as to fit into a recess in the part. As described above, the magnets are attracted so as to be fitted in the concave portions surrounded by the convex portions, so that the relative displacement between the housing 1 and the mounting member 2 is almost eliminated, and the magnets are attached to predetermined positions. .
Further, as shown in FIG. 3 showing a plan view of the mounting state, the mounting screw 6 is passed through the screw fixing hole 23 (see FIG. 1) of the upright piece 22 of the mounting member 2, thereby By screwing into a screw hole 12 (see FIG. 1) formed on the upper surface of the body 1, the housing 1 and the attachment member 2 are attached not only with a magnet but also with a screw 6.
Therefore, since the housing 1 cannot be removed easily, an effect of preventing theft can be obtained. In particular, by making the screw 6 a screw having a structure that cannot be loosened unless a special tool is used, the effect of preventing theft can be further ensured.

The back surface 11 of the housing 1 corresponds to the first member described in the claims, and the magnet 3 corresponds to the magnet described in the claims and the first concavo-convex structure. The member 2 corresponds to the second member described in the claims, and the convex portion 5 corresponds to the second concavo-convex structure described in the claims, and the magnet 3 and the convex portion 5. Corresponds to the position defining structure described in the claims.
Further, the housing screw 1 is passed through the screw fixing hole 23 of the standing piece 22 of the mounting member 2 and screwed into the screw hole 12 formed on the upper surface of the housing 1, whereby the housing 1 is attached to the mounting member 2. The structure to be attached to corresponds to the screwing structure described in the claims.

In the first embodiment of the present invention, as shown in FIGS. 1, 2, and 3, the magnet 3 is fixed to the housing 1, the wall surface to be attached is an iron attachment member 2, and the position restricting structure is an attachment member. 2, the convex part 5 surrounding the magnet was formed. Further, as a screwing structure, the standing piece 22 provided on the attachment member 2 is screwed into the screw hole 12 of the housing 1 with the screw 6.
Further, since the attachment member 2 has a projection shape substantially the same as the projection shape onto the wall surface in the attached state, an effect that the attachment member 2 on the rear surface of the housing 1 is not conspicuous is obtained.

In addition, as a form which implements this invention, it is not limited to the above Example 1, You may fix a magnet to the direction of the attachment member 2. FIG. In addition, when a plurality of magnets are used, it is possible to prevent positional deviation and increase the attractive force, but even a single position-regulating structure can be realized.
Moreover, as a magnetic body, the ferromagnetic body containing iron, cobalt, and nickel is preferable. Moreover, if it is a ferromagnetic body, it does not need to be magnetized, but if it is magnetized to the polarity of the direction to adsorb | suck, still stronger attraction | suction force will be acquired. Although the whole mounting member 2 may be formed of a magnetic material as in the first embodiment, at least only the attracting position corresponding to the magnet may be used.
Further, the screwing structure is not limited to the configuration of the first embodiment, and a standing piece may be provided on the housing and screwed to the mounting member.

Further, the position defining structure is not limited to the structure of Example 1,
For example, you may form the recessed part into which the magnet of the housing | casing in an adsorption | suction state fits in an attachment member. Or a magnet may be fixed to the recessed part formed in the back surface of a housing | casing, and the convex part which fits in the said recessed part may be formed in an attachment member. Further, a concave portion may be formed at the center of the magnet, and a convex portion that fits into the concave portion may be formed on the mounting member. Conversely, the same applies to the case where a magnet is fixed to the mounting member, and the description thereof is omitted.

  The mounting structure of the housing of the present invention can be applied not only to electronic devices but also to mounting of gas alarms, lighting fixtures, and ornaments.
