[0003] [Patent Document 1] JP 2014-68237 A Summary of the Invention [Problem to be solved by the invention]

[0004] Conventionally, in the above-mentioned installation work, particularly with regard to connecting the cable, the worker must hold the intercom device in one hand and the cable in the other hand. Therefore, even if a connector is provided at the end of the cable, the work of connecting the cable to the intercom device and the installation work of the intercom device are troublesome. In addition, there is a problem that there is no means for temporarily holding the intercom device when the worker wants to refer to the instruction manual while connecting the cable.

[0005] Therefore, the present invention has been made in consideration of the above problems, and aims to provide an installation structure for an intercom device that allows the intercom device to be installed on a wall surface more easily than before. [Means for solving the problem]

[0006] In order to achieve the above-mentioned object, the invention described in claim 1 of the present invention is an installation structure for installing an intercom device on a wall surface with a mounting plate fixed to the wall interposed between the rear surface of the intercom device and the wall surface, wherein the mounting plate is provided with a fixing portion to which the intercom device is fixed when installed on the wall surface, and a temporary holding portion at a position separate from the fixing portion, capable of temporarily holding the intercom device in an upside-down position compared to when it is installed, and when the intercom device is temporarily held in the temporary holding portion, the mounting plate and the intercom device at least partially overlap in the front-to-rear direction. According to the invention described in claim 1, the mounting plate is provided with a fixing portion to which the intercom device is fixed when the intercom device is installed on the wall surface, and a temporary holding portion at a position separate from the fixing portion, which is capable of temporarily holding the intercom device in an upside-down position from when the intercom device was installed, so that the cable can be connected to the intercom device while the intercom device is temporarily held in an upside-down position in the temporary holding portion, and it is easy to respond to situations such as when the user wants to refer to the instruction manual while connecting the cable, and the intercom device can be installed on the wall surface more easily than before. In addition, when the intercom device is temporarily held in the temporary holding portion, the mounting plate and the intercom device overlap at least partially in the front-to-rear direction, so that the temporarily held intercom device is less likely to come into contact with the wall, and it is possible to prevent the intercom device from being accidentally damaged during the installation work.

[0007] In addition, the invention described in claim 2 is characterized in that, in the invention described in claim 1, the fixing part is a hanging piece that protrudes forward and has a tip bent upward, and when the intercom device is temporarily held in the temporary holding part, the hanging piece abuts against the surface of the intercom device. According to the invention described in claim 2, the fixing part is a hanging piece that protrudes forward and has a tip bent upward, and when the intercom device is temporarily held in the temporary holding part, the hanging piece abuts against the surface of the intercom device, making it extremely unlikely that the temporarily held intercom device will come into contact with the wall, thereby reliably preventing the intercom device from being inadvertently damaged during installation work. Effect of the Invention

[0008] According to the present invention, the mounting plate is provided with a fixing portion to which the intercom device is fixed when the intercom device is installed on the wall surface, and a temporary holding portion at a position separate from the fixing portion, which is capable of temporarily holding the intercom device in an upside-down position from when the intercom device was installed, so that the cable can be connected to the intercom device while the intercom device is temporarily held in an upside-down position in the temporary holding portion, and it is easy to respond to requests such as when the user wishes to refer to an instruction manual while connecting the cable, and the intercom device can be installed on the wall surface more easily than in the past. In addition, when the intercom device is temporarily held in the temporary holding portion, the mounting plate and the intercom device at least partially overlap in the front-to-rear direction, so that the temporarily held intercom device is less likely to come into contact with the wall, and it is possible to prevent the intercom device from being accidentally damaged during the installation work.

FIG. 7 is an explanatory diagram showing the state in which the intercom master unit 1 is placed on the mounting pieces 12, 12 in an upside-down position from the rear diagonally lower left. FIG. 8 is an explanatory diagram showing a cross section taken along line AA 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 synthetic resin plate molded into a substantially rectangular shape when viewed from the front, and has a cable opening 11 at its substantially central location for drawing out a cable (not shown) extending from the wall side to the front of the mounting plate 10. Furthermore, arm pieces 16 that protrude outward on the left and right sides are provided at substantially central locations in the vertical direction on the left and right sides of the mounting plate 10. Each arm piece 16 is provided with a mounting piece 12 that protrudes forward and has a tip bent upward. Furthermore, upper hook pieces 13, 13 are provided at the upper left and right corners of the mounting plate 10 for integrating the mounting plate 10 with the main body case 2 of the intercom master unit 1. Each upper hook piece 13 protrudes forward from the surface of the mounting plate 10 and has a tip bent upward. Furthermore, lower hook pieces 14 for integrating the mounting plate 10 with the main body case 2 of the intercom master unit 1 are respectively provided at the lower left and right corners of the mounting plate 10 so as to protrude forward, and have the same shape as the upper hook piece 13. 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. A mounting recess 21 recessed forward is provided on the rear side of the main body case 2, and the mounting plate 10 fits into the mounting recess 21 when the main body case 2 is fixed to the mounting plate 10. The mounting recess 21 also has upper slits 22, 22 into which the upper hook pieces 13, 13 enter when the main body case 2 is fixed to the mounting plate 10. Each upper slit 22 is a recess recessed forward and extends in the vertical direction. Adjacent to the upper end of each upper slit 22, an upper hook portion 23 is provided, which opens downward, i.e., into the upper slit 22, and can hook the upper hook piece 13 that enters the upper slit 22 as the main body case 2 slides downward.

[0015] Meanwhile, lower slits 24, 24, which are recesses recessed forward like the upper slits 22, are provided extending in the vertical direction within the mounting recess 21 below the upper slits 22. The lower hook pieces 14 can enter into each lower slit 24 when fixed to the mounting plate 10. Also, adjacent to the upper end of each lower slit 24, there is provided a lower hooked portion 25 that opens downward, i.e., into the lower slit 24, and can hook the lower hook pieces 14 that enter the lower slit 24 as the main body case 2 slides downward.

[0016] Furthermore, the mounting recess 21 is provided with storage recesses 26, 26 capable of storing the mounting pieces 12, 12 when the mounting recess 21 is fixed to the mounting plate 10. Each storage recess 26 is a recess recessed forward and extends in the vertical direction, similar to the upper slit 22 and the lower slit 24. In addition, the lower left and right corners of the rear surface of the main body case 2 are provided with forward recessed latching steps 27, 27, and when the main body case 2 is placed on the mounting pieces 12, 12 as described below, the bent portions of the mounting pieces 12, 12 can be latched on the latching steps 27, 27. A connector (not shown) to which a cable is connected is provided at approximately the center of the mounting recess 21.

[0017] Here, a method for mounting the intercom master unit 1 on a wall surface using the mounting plate 10 will be described. First, mounting plate 10 is oriented so that mounting pieces 12, 12 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 cable opening 11 beyond mounting plate 10. Next, intercom master unit 1 is placed on mounting pieces 12, 12, and intercom master unit 1 is temporarily held by mounting plate 10. At this time, as shown in Figures 5 to 7, intercom master unit 1 is inverted. That is, the rear surface of main body case 2 faces forward, and the connector is exposed forward in the temporary holding position, and the bent portions of mounting pieces 12, 12 are hooked to hooked steps 27, 27, and the bottom surface of main body case 2 is placed on mounting pieces 12, 12. Then, intercom master unit 1 is temporarily held on mounting plate 10 at a higher position than when it was installed, i.e., at a different position from when it was installed, and cable opening 11 and the cable pulled out from cable opening 11 are exposed on the lower side of intercom master unit 1. In addition, in this temporarily held state, mounting plate 10 is interposed between monitor unit 3 of intercom master unit 1 and the wall surface in the front-to-rear direction. In particular, upper hook pieces 13, 13 abut against the surface of monitor unit 3, preventing monitor unit 3 from contacting the wall surface.

[0018] Furthermore, while still in the temporarily held state, the drawn-out cable is connected to the connector exposed on the rear surface of the main body case 2. Finally, after removing the intercom master unit 1 from the mounting pieces 12, 12, the rear surface of the main body case 2 is placed in an installation position facing backward, and the intercom master unit 1 is fixed to the mounting plate 10, completing the installation of the intercom master unit 1 on the wall surface. When fixing to the mounting plate 10, the intercom master unit 1 is placed in the above-mentioned position, and while the mounting pieces 12, 12 are positioned in the accommodation recesses 26, 26, the mounting plate 10 is arranged in the mounting recess 21 so that the upper hook pieces 13, 13 are positioned in the upper slits 22, 22 and the lower hook pieces 14, 14 are positioned in the lower slits 24, 24, respectively. Thereafter, by sliding the intercom master unit 1 downward, the upper latch pieces 13, 13 are latched to the upper latched portions 23, 23, and the lower latch pieces 14, 14 are latched to the lower latched portions 25, 25, respectively, and the intercom master unit 1 is fixed to the mounting plate 10.

[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 upper hook pieces 13, 13 and the lower hook pieces 14, 14 to which the intercom master unit 1 is fixed when the intercom master unit 1 is installed on the wall surface, and the placement pieces 12, 12 capable of temporarily holding the intercom master unit 1 in an upside-down position from when the intercom master unit 1 is installed at a position different from the two hook pieces 13, 14. Therefore, in the temporary holding state in which the intercom master unit 1 is placed on the placement pieces 12, 12 in an upside-down position, the work of connecting the cable to the intercom master unit 1 can be performed, and it is also easy to respond to cases such as when the user wants to refer to the instruction manual during the cable connection work. Therefore, the intercom master unit 1 can be installed on the wall surface more easily than in the past. Also, in the temporary holding state in which the intercom master unit 1 is placed on the placement pieces 12, 12, the mounting plate 10 is interposed between the monitor unit 3 of the intercom master unit 1 and the wall surface in the front-rear direction, that is, the mounting plate 10 and the intercom master unit 1 at least partially overlap in the front-rear direction. Therefore, the monitor unit 3 of the temporarily held intercom master unit 1 is unlikely to come into contact with the wall, and it is possible to prevent a situation in which the monitor unit 3 is inadvertently damaged during the installation work.

[0020] In addition, the upper hanging piece 13 protrudes forward with its tip bent upward, and when the intercom master unit 1 is temporarily held on the mounting pieces 12, 12, the upper hanging pieces 13, 13 come into contact with the surface of the intercom master unit 1, particularly the monitor unit 3. This makes it extremely unlikely that the monitor unit 3 of the intercom master unit 1 in the temporarily held state will come into contact with the wall, thereby reliably preventing the monitor unit 3 from being inadvertently damaged during the installation work.

[0021] Furthermore, 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. In addition, a bent portion bent upward is provided at the tip of the mounting piece 12 protruding forward from the mounting plate 10, while a latching step portion 27, 27 is provided on the rear surface of the main body case 2 to which the bent portion can be latched when placed on the mounting pieces 12, 12.This makes it possible to stabilize the placement of the intercom master unit 1 on the mounting pieces 12, 12, making it even easier to install the intercom master unit 1 on a wall surface.

[0022] The installation structure of the intercom device according to the present invention is in no way limited to the above-described embodiment, and the overall configuration of the intercom device and mounting plate, as well as the configuration relating to the fixing portion and temporary holding portion, etc., can be appropriately modified as necessary without departing from the spirit of the present invention.

[0023] For example, in the above embodiment, arm pieces are provided protruding to the left and right from the mounting plate, and a mounting piece is provided on the arm piece as a temporary holding portion, but instead of providing such an arm piece, the temporary holding portion may be provided so as to protrude forward from the central part of the mounting plate, or an arm piece is provided protruding downward from the mounting plate and a temporary holding portion is provided on the arm piece, and the position of the temporary holding portion may be anywhere as long as the mounting plate and the intercom device at least partially overlap in the fore-and-aft direction in the temporary holding state.

[0024] In the above embodiment, the temporary holding portion is provided as a mounting piece on which the intercom device can be placed, but the specific configuration of the temporary holding portion can be appropriately modified in design, and there is no problem if, for example, a claw-shaped temporary holding portion that can engage with the intercom device is provided, or a hook-shaped temporary holding portion on which the intercom device can be hung is provided. Similarly, the fixing portion can also be adopted as a fixing portion having a shape other than the hook piece as in the above embodiment, and when the intercom device is temporarily held by the temporary holding portion, the fixing portion does not necessarily have to abut against the surface of the intercom device.

[0025] 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 without providing such a storage recess and so that the temporary holding portion remains exposed when installed. Furthermore, in the above embodiment, when the intercom device is temporarily held in the temporary holding portion, it is not turned upside down; however, it is also possible to provide a temporary holding portion that can temporarily hold the intercom device not only upside down but also upside down.

[0026] 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 hall collective units, so long as they are installed on a wall surface via a mounting plate.
