Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to an electronic device that can be used as both a desktop type and a wall-mounted type, for example, a desktop stand mounting device in a base unit of an intercom.

(B) Conventional technology In an electronic device that can be used as both a desktop type and a wall-mounted type, as represented by an intercom base unit, when used as a desktop type, a desktop stand was attached to the bottom of the electronic device. 3 and 4 show a conventional desk stand mounting structure. FIG. 3 is an exploded perspective view as seen from the bottom of the electronic device. Reference numerals 1a, 1b, 1c, and 1d denote a plurality of mounting holes provided on the bottom 2 and engaging portions provided on the tabletop stand 3. 4a, 4
The tabletop stand is fixed to the bottom 2 by inserting b, 4c, and 4d. The reason for providing a large number of engaging portions is to obtain the required fixing strength. Further, not only the engaging portion but also the one which is further fixed by using screws 5a and 5b as shown in FIG.

On the other hand, when it is used as a wall-mounted type, a wall-mounted mounting member is used without using a desk stand. The wall-mounting mounting member is fixed to the wall surface with a screw or the like, and is provided in the wall-mounting mounting member in a mounting hole different from the mounting hole used when mounting the tabletop stand provided at the bottom of the electronic device. It is fixed to the wall surface by inserting and engaging the engaging portion.

(C) Problems to be Solved by the Invention In the mounting structure for the tabletop stand described in the related art, a large number of mounting holes and engaging portions are required in addition to the mounting member for wall hanging in order to obtain the fixing strength. . Providing a large number of mounting holes at the bottom of the electronic device means inserting the engaging part of the tabletop stand into more of the electronic device, affecting the storage space of the circuit board, etc. in the electronic device, This will hinder the miniaturization, especially the thinning.

(D) Means for Solving the Problems In order to solve the above problems, the present invention provides a first and a second mounting hole provided in a bottom portion of an electronic device and a first mounting hole that engages with the first mounting hole. In the direction different from the engaging portion of the wall mounting member having the engaging portion and the hole for inserting the first screw member screwed into the wall surface and the engaging portion of the wall mounting member in the second mounting hole. It has a 2nd engaging part which engages, and a desk stand which has a leg part which separates the bottom of the above-mentioned electronic equipment from a table top, The 1st engaging part of the mounting member for the wall hangings, and the table stand And a second screw member for connecting the wall mounting member and the desk stand in a state where the second engaging portion is engaged with the first and second mounting holes, respectively.

(E) Operation Therefore, according to the present invention, the wall mounting member and the desk stand are engaged with the bottom of the electronic device and cannot be disengaged together.

(F) Embodiment An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is an exploded perspective view of an intercom master unit according to an embodiment of the present invention as seen from the bottom, and FIG. 2 is a completed assembly diagram thereof. The x, y, and z arrows in the figure indicate the directions of the three-dimensional space. In FIG. 1, 11 is an intercom base unit 10
, 12 is a metal wall mounting member, and 13 is a tabletop stand which is a plastic molded product. On the bottom 11 is a power cord 14 that supplies a power audio signal to the intercom base unit 10.
Connection terminal for connecting to various peripheral devices
And the engaging portions 16a, 16 provided on the wall mounting member 12
First mounting holes 17a, 17b, 17c, 17 engaging with b, 16c, 16d
d and the engaging portions 18a, 18 provided on the tabletop stand 13
Second mounting holes 19a and 19b that engage with b are provided. When using the intercom base unit 10 as a desktop type,
Attach the tabletop stand 13. To mount the desktop stand 13, first mount the wall mounting member 12. Engagement part 16
After inserting a, 16b, 16c, and 16d into the first mounting holes 17a, 17b, 17c, and 17d, respectively, slide the wall mounting member 12 in the positive x direction to mount it on the wall as shown in FIG. The mounting member 12 and the bottom portion 11 are engaged with each other, and the movement in the y direction and the z direction is restricted. By engaging the engaging portions 18a, 18b provided on both sides of the tabletop stand 13 with the second mounting holes 19a, 19b, movement in the x direction and the z direction is restricted. Since the mounting holes 19a and 19b in FIG. 1 are provided at positions close to the side surface of the intercom master unit 10, the engaging portions 18a and 18b are avoided by avoiding the circuit board (not shown) provided near the bottom 11. Is inserted.
Furthermore, the screw hole 20 provided in the wall mounting member 12 and the screw
When the table-top stand 13 and the wall-mounting attachment member 12 are joined together by using 21, the state shown in FIG. 2 is obtained.

Therefore, the desk stand 13 is restricted in movement in the y direction,
Since the wall mounting member 12 is restricted in the movement in the x direction and further coupled by using the screw 21, it does not move together in the xy plane and thus does not come off from the bottom portion 11. That is, the tabletop stand 13 includes the engaging portions 16a, 1a of the wall-mounting mounting member 12.
Sufficient fixing strength is obtained with the help of 6b, 16c, 16d.

When the intercom master device 10 is used as a wall-mounted type, the desk stand 13 is not used and only the wall-mounted mounting member 12 is used. Holes 21a, 21b, 21c, 21d in the wall mounting member 12
Is provided and a wood screw (not shown) is inserted in the positive z direction and fixed to the wall surface, and the first mounting holes 17a, 17b,
The intercom base unit 10 is fixed to the wall surface by inserting and engaging the engaging portions 16a, 16b, 16c, 16d into the 17c, 17d.

(G) According to the effect of the invention, according to the invention, the required fixing strength can be obtained even if the engaging portion of the tabletop stand is reduced, and the mounting hole provided at the bottom of the electronic device can be reduced. It is possible to reduce the influence on the storage space of the circuit board or the like in the electronic device. Further, since it is mounted together with the wall mounting member, the wall mounting member is not lost, and the effect is great.
