Fig. 11 is an explanatory diagram showing the intercom master unit 1 from below rear left while it is being fixed to the mounting plate 10. Fig. 12 is an explanatory diagram showing an enlarged view of the hooking portion of the upper hook piece 13 in the cross section taken along line AA in Fig. 1. Fig. 13 is an explanatory diagram showing the cross section taken along line BB in Fig. 1.

[0012] The intercom master unit 1 has a roughly rectangular box-shaped main body case 2, and a monitor unit 3 is provided on the front of the main body case 2. A touch panel is used for the monitor unit 3, and the monitor unit 3 also functions as an operation unit for, for example, responding to calls from an intercom slave unit (not shown). The intercom master unit 1 is installed on a wall surface via a mounting plate 10.

[0013] First, the structure of the mounting plate 10 will be described. The mounting plate 10 is a metal plate formed into a substantially rectangular shape when viewed from the front, and a cable opening 11 is provided at a substantially central location for drawing out a cable (not shown) extending from the wall side to the front of the mounting plate 10. Furthermore, a mounting piece 12 is provided at the left and right parts of the upper edge of the mounting plate 10, protruding forward from the upper edge of the mounting plate 10 and having its tip bent upward. Furthermore, upper hook pieces 13 are provided at the upper ends of both the left and right edges of the mounting plate 10 to protrude outward to the left and right, respectively, for integrating the mounting plate 10 with the main body case 2 of the intercom master unit 1. Furthermore, lower hook pieces 14 are provided at the lower ends of both the left and right edges of the mounting plate 10 to protrude outward to the left and right, respectively, for integrating the mounting plate 10 with the main body case 2 of the intercom master unit 1. In addition, near the upper hook pieces 13, 13 on the mounting plate 10, click holes 16, 16 into which click protrusions 29, 29 described below fit when fixing the intercom master unit 1. The mounting plate 10 is also provided with a plurality of fixing holes 15, 15... for screwing to a mounting box or the like embedded in a wall.

[0014] Next, the structure of the rear side of the main body case 2 will be described. The rear side of the main body case 2 is provided with a mounting recess 21 recessed forward, so that the mounting plate 10 fits into the mounting recess 21 when the main body case 2 is fixed to the mounting plate 10. In addition, upper ribs 22 protruding like eaves toward the rear of the mounting recess 21 are provided at the upper left and right corners of the mounting recess 21. The mounting recess 21 and each upper rib 22 are separated from each other in the front-rear direction by approximately the same amount as the thickness of the upper hook piece 13 in the front-rear direction. The space surrounded by the mounting recess 21 and each upper rib 22 opens downward and inward to the left and right, and forms an upper hook space 23 in which the upper hook piece 13 can be hooked when inserted. Furthermore, click protrusions 29, 29 that fit into the click holes 16, 16 when the main body case 21 is fixed to the mounting plate 10 are provided in the mounting recess 21 at positions adjacent to the upper ribs 22, 22 and protrude rearward.

[0015] Meanwhile, lower ribs 24 that protrude like eaves toward the rear of the mounting recess 21 are provided at the left and right lower corners of the mounting recess 21, similar to the upper ribs 22. The mounting recess 21 and each lower rib 24 are separated in the front-to-rear direction by approximately the same amount as the thickness in the front-to-rear direction of the lower hook piece 14. The space surrounded by the mounting recess 21 and each lower rib 24 opens downward and inward to the left and right, forming a lower hook space 25 into which the lower hook piece 14 can be inserted and hooked.

[0016] Furthermore, at the upper end of the rear surface of the main body case 2, storage recesses 26, 26 are recessed forward into which the mounting pieces 12, 12 can enter when fixed to the mounting plate 10. Furthermore, at the lower end of the rear surface of the main body case 2, fitting recesses 27, 27 are recessed forward into which the folded portions of the mounting pieces 12, 12 can fit when the main body case 2 is placed on the mounting pieces 12, 12 as described below. In addition, a connector 28 to which a cable is connected is provided in the center of the rear surface of the main body case 2.

[0017] Here, a method for mounting the intercom master unit 1 on a wall surface using the mounting plate 10 will be described. First, the mounting plate 10 is oriented so that the mounting pieces 12, 12 are located upward and protrude forward, and is attached to the wall surface by screwing it to a mounting box or the like embedded in the wall, and the cable is drawn forward from the cable opening 11 beyond the mounting plate 10. Next, the intercom master unit 1 is placed on the mounting pieces 12, 12. At this time, as shown in Figs. 8 and 9, the intercom master unit 1 is inverted upside down. That is, the rear surface of the main body case 2 faces forward, and the connector 28 is exposed forward in a temporary placement position, and the bent portions of the mounting pieces 12, 12 are positioned within the fitting recesses 27, 27, and the lower surface of the main body case 2 is placed on the mounting pieces 12, 12. Then, the intercom master unit 1 is supported by the mounting plate 10 at a higher position than when it was installed, and the cable opening 11 and the cable drawn from the cable opening 11 are exposed below the intercom master unit 1.

[0018] Furthermore, while still in the above-mentioned installed state, the drawn-out cable is connected to the exposed connector 28. Finally, after removing the intercom master unit 1 from the mounting pieces 12, 12, the intercom master unit 1 is fixed to the mounting plate 10 in an installation position in which the rear surface of the main body case 2 faces backward, and the installation of the intercom master unit 1 on the wall surface is completed. When fixing to the mounting plate 10, the intercom master unit 1 is in the above-mentioned position, and while the mounting pieces 12, 12 are positioned in the accommodation recesses 26, 26 as shown in Figures 10 and 11, the mounting plate 10 is arranged in the mounting recess 21 so that the upper hook pieces 13, 13 are positioned below the upper hook spaces 23, 23 and the lower hook pieces 14, 14 are positioned below the lower hook spaces 25, 25, respectively. Thereafter, by sliding the intercom master unit 1 downward, the upper hook pieces 13, 13 enter the upper hook spaces 23, 23 and the lower hook pieces 14, 14 enter the lower hook spaces 25, 25, respectively, and the intercom master unit 1 is fixed to the mounting plate 10. In addition, as the intercom master unit 1 is fixed, the click protrusions 29, 29 fit into the click holes 16, 16, so the worker can confirm that the intercom master unit 1 is fixed to the mounting plate 10 by the clicking sensation that is obtained at that time.

[0019] According to the installation structure of the intercom master unit 1 having the above-mentioned configuration, the mounting plate 10 is provided with the placement pieces 12, 12 on which the intercom master unit 1 can be placed higher than when installed and in an upside-down position from when installed. Therefore, by placing the intercom master unit 1 in an upside-down position on the placement pieces 12, 12, the cable can be pulled out forward from below the intercom master unit 1 and connected to the connector 28 on the rear surface of the main body case 2. Therefore, the work of connecting the cable to the intercom master unit 1 can be performed, and the intercom master unit 1 can be installed on the wall more easily than before.

[0020] In addition, since the rear surface of the main body case 2 is provided with storage recesses 26, 26 capable of storing the mounting pieces 12, 12 when installed, the mounting pieces 12, 12 are not exposed around the intercom master unit 1 in the installed state, and the appearance in the installed state is not marred. Furthermore, a bent portion bent upward is provided at the tip of the mounting piece 12 protruding forward from the mounting plate 10, while engaging recesses 27, 27 are provided on the rear surface of the main body case 2 into which the bent portion can fit when placed on the mounting pieces 12, 12. This makes it possible to stabilize the positioning of the intercom master unit 1 on the mounting pieces 12, 12, and makes it even easier to install the intercom master unit 1 on a wall surface.

[0021] In addition, the installation structure of the intercom device according to the present invention is not limited to the above-described embodiment, and the overall configuration of the intercom device and mounting plate, as well as the configuration related to the support means, etc., can be appropriately modified as necessary without departing from the spirit of the present invention.

[0022] For example, in the above embodiment, the mounting piece is provided as a support means on the upper edge of the mounting plate, but the position of the support means may be anywhere as long as it can be supported above the installed position. In addition, in the above embodiment, a supporting piece on which the intercom device can be placed is provided as a supporting means, but the specific configuration of the supporting means can be modified in design as appropriate, and there is no problem in providing, for example, a claw-shaped supporting means that can engage with the intercom device, or a hook-shaped supporting means on which the intercom device can be hung.

[0023] Furthermore, in the above embodiment, a storage recess capable of storing the mounting piece when installed is provided on the rear surface of the main body case of the intercom device, but it is also possible to configure the device so that no such storage recess is provided and the support means remains exposed when installed. Furthermore, in the above embodiment, when the intercom device is supported on the support means, it is not turned upside down, but it is also possible to provide a support means that can support the intercom device not only upside down but also upside down.

[0024] In addition, while the above embodiment describes the installation structure of an intercom master unit, which is an example of an intercom device, the present invention can also be suitably adopted as an installation structure for other intercom devices, such as intercom slave units and entrance group units, so long as they are installed on an installation surface via a mounting plate.
