DETAILED DESCRIPTION OF THE INVENTION

[0011] Hereinafter, a detailed description will be given of a wall surface installation structure of a collective entrance unit according to one embodiment of the present invention with reference to the drawings.

[0012] FIG. 1 is an explanatory perspective view from the front of the collective entrance device 1 installed on the surface of a wall W. FIG. 2 is an explanatory perspective view from the front of the collective entrance device 1, fixed frame 13, and mounting box 12. FIG. 3 is an explanatory view showing an enlarged view of the bottom edge of the fixed frame 13. FIG. 4 is an explanatory view showing the positional relationship between the sensor board 20 and the magnet 16. FIG. 5 is a block diagram of the collective entrance device 1.

[0013] First, the structure of the collective entrance unit 1 will be described. The collective entrance unit 1 is used as part of a so-called apartment complex intercom system and has a main body case 2 consisting of a front case located at the front and a rear case located at the rear. The upper front surface of the main body case 2 is provided with a speaker 3 and a microphone 4 (shown in FIG. 5) for communicating with an intercom master unit (not shown) installed in each dwelling unit, and a camera unit 5 for capturing images in front of the main body case 2. A touch panel is also provided in the approximate center of the front surface of the main body case 2, serving as an operation unit 6 for allowing a visitor to select the dwelling unit to call and for performing calling operations related to calling a resident. The main body case 2 also houses a control unit 7 that controls the main operations of the collective entrance unit 1, such as communication with the intercom master unit, and a communication unit 8 that communicates audio data and image data captured by the camera unit 5 with the intercom master unit. Such an apartment entrance unit 1 is installed on the surface of a wall W such as the entrance of an apartment building as will be described later, and when a visitor operates the operation unit 6 to specify the apartment to call and performs the call operation, the intercom master unit of the corresponding apartment is called and the camera unit 5 is activated to take a photo of the visitor. 9 is a decorative cover attached to the front of the main body case 2.

[0014] Next, the anti-theft function of the entrance hall unit 1 and the installation structure of the entrance hall unit 1 will be described. A sensor board 20 equipped with a magnetic sensor 11 (shown in FIG. 5) is installed inside the main body case 2 of the multiple entrance device 1, and the sensor board 20 is electrically connected to a main board (not shown) that constitutes the control unit 7. In other words, the control unit 7 is able to detect magnetism using the magnetic sensor 11.

[0015] The above-described collective entrance unit 1 is installed on the surface of a wall W via a mounting box 12 and a fixing frame 13. The mounting box 12 is embedded in the wall as in the past, and has a rectangular box shape with an open front and includes an upper panel, a lower panel, a back panel, and left and right side panels. The box is large enough to accommodate the rear of the main body case 2. Mounting pieces 14 for fixing the fixing frame 13 are provided on the inner surfaces of the left and right side panels of the mounting box 12. The fixing frame 13 is a rectangular metal frame having an upper edge, a lower edge, and left and right side edges, and is large enough to be accommodated within the mounting box 12 with each edge aligned with the inner surface (top, bottom, and left and right side surfaces) of the opening side of the mounting box 12. Fixing pieces 15, 15 are provided on the left and right side edges of the fixing frame 13 for screwing the fixing frame 13 to the mounting pieces 14. Furthermore, fixing holes 18 for screwing the main body case 2 are drilled on both the upper and lower sides of the fixed frame 13. In addition, a magnet holder 17 for holding a magnet 16 is attached to the lower side of the fixed frame 13.

[0016] The installation of the multiple entrance unit 1 on the surface of the wall W using the mounting box 12 and fixing frame 13 can be performed as follows. First, the mounting box 12 is embedded in the wall W, and then the fixing frame 13 is fixed to the mounting box 12. Next, the main body case 2 is fitted into the fixing frame 13, and the main body case 2 is screwed to the fixing frame 13. Finally, the decorative cover 9 is attached to the front of the main body case 2, completing the installation of the multiple entrance unit 1 on the surface of the wall W. In this installed state, the magnetic sensor 11 and the magnet 16 on the sensor board 20 face each other from the front to the back, and the control unit 7 is able to detect the magnetic force of the magnet 16.

[0017] In the collective entrance unit 1 installed as described above, the control unit 7 constantly monitors the magnetism of the magnet 16 using the magnetic sensor 11. Therefore, if, for example, a malicious person attempts to remove the collective entrance unit 1 from the fixed frame 13, the relative positions of the magnetic sensor 11 and the magnet 16 change, and the control unit 7 can detect this situation based on the detection results of the magnetic sensor 11. Therefore, the control unit 7 activates the speaker 3 to sound an alarm, alerting those in the vicinity that there is a risk of theft.

[0018] According to the collective entrance unit 1 and its installation structure configured as described above, a magnet holder 17 for holding a magnet 16 is attached to the fixed frame 13, while a magnetic sensor 11 capable of detecting the magnet 16 is built into the main body case 2 of the collective entrance unit 1 in a position facing the magnet 16. The control unit 7, which controls the main operation of the collective entrance unit 1, constantly monitors the magnetic field of the magnet 16 using the magnetic sensor 11. If the relative positions of the magnetic sensor 11 and the magnet 16 change, for example, because the collective entrance unit 1 is about to be removed from the fixed frame 13, the control unit 7 activates the speaker 3 to sound an alarm. This effectively prevents theft of the collective entrance unit 1 installed on the surface of the wall W. Furthermore, because the anti-theft function utilizes the conventionally known speaker 3 and fixed frame 13, the configuration is streamlined, allowing for low-cost implementation and a more compact collective entrance unit 1.

[0019] In addition, the intercom device and the installation structure of the intercom device according to the present invention can be appropriately modified as needed, not only in terms of the overall configuration of the intercom device, but also in terms of the configuration of the mounting box and fixing frame, etc., within the scope of the spirit of the present invention.

[0020] For example, although the above embodiment describes the installation of a collective entrance unit, the present invention can also be suitably employed as an installation structure for other intercom devices such as intercom slave units, and other intercom devices. In addition, in the above embodiment, the magnet holder is attached to the lower edge of the fixed frame, but the magnet holder may also be attached to the side or upper edge of the fixed frame, or the magnet holder may be attached to the mounting box instead of the fixed frame, or a magnet may be embedded separately in the wall.

[0021] Furthermore, there is no problem with a configuration in which monitoring is performed at multiple locations, such as by attaching magnet holders to the upper and lower sides of the fixed frame. In addition, in the above embodiment, a speaker is provided as the warning means and a warning sound is emitted from the speaker, but the design can be changed as appropriate regarding what kind of member is provided as the warning means, the number of warning means, etc. For example, a dedicated lamp may be provided and the control unit may blink the lamp based on the detection result of the magnetic sensor.
