[0018] [First embodiment] Hereinafter, a door device according to a first embodiment of the present invention will be described with reference to Figs.

[0019] As shown in Fig. 1, a door device 100 according to the first embodiment is a device that is installed and used on a door 10 of an existing building. The door 10 is composed of a door 11 and a frame 12. The door 11 is an opening / closing type door that moves outside the surface of the frame 12. The frame 12 is in contact with an opening wall material of the building to which the door 11 is attached. The door 11 of the door 10 is provided with a thumb turn 13 for locking and unlocking the lock, and a locking / unlocking device 20 for driving the thumb turn 13 is installed on the indoor side surface 11b of the door 11.

[0020] As shown in FIG. 2, the locking / unlocking device 20 is a device that is attached to an existing door 11, and includes a housing 21 installed on the indoor side surface 11b of the door 11, and a clamping unit 22 that clamps the thumb turn 13. The housing 21 is fixed to the indoor side surface 11b of the door 11 with double-sided tape, and houses a control board, a motor, and a power transmission mechanism inside. The control board is equipped with a Bluetooth (registered trademark) module, a microcomputer, a driver circuit, and a power circuit that supplies power to these components. The Bluetooth module is a module that functions as a short-range wireless communication unit, and is capable of wireless communication with the authentication device 110 (FIG. 1) provided in the door device 100 of this embodiment. The microcomputer has a built-in CPU and memory, and the CPU executes a program stored in the memory to output a control signal that controls the rotation direction and rotation step of the motor to the drive circuit according to the unlock command received by the Bluetooth module. In this way, the microcomputer functions as a control unit that controls the rotation of the motor. The drive circuit is a circuit that drives the motor, and outputs drive power to the motor based on a control signal input from a microcomputer. The motor rotates based on the power input from the drive circuit. The shaft of the motor is connected to a power transmission mechanism composed of multiple gears, and the output shaft of the power transmission mechanism is connected to the clamping unit 22. As a result, the clamping unit 22 rotates in response to the rotation of the motor, and the thumb turn 13 rotates as the clamping unit rotates.

[0021] Returning to FIG. 1, the door device 100 of this embodiment includes an authentication device 110 capable of communicating with the locking / unlocking device 20, and an installation tool 130 for installing the authentication device 110 on the door 10.

[0022] The authentication device 110 is a device that authenticates people entering or exiting a building through the door 10, and in this embodiment, is composed of a well-known smart device 111 on which an authentication application (hereinafter referred to as an "authentication app") is installed, and a housing 112 that houses the smart device 111.

[0023] The smart device 111 is a smartphone or tablet terminal, and has a touch panel display, a camera module, a Bluetooth (registered trademark) module, and a speaker. The touch panel display functions as a display unit that displays information input from the CPU of the smart device 111. The touch panel display also functions as a position input unit that inputs the touch position to the CPU when a touch operation is performed by the user. The camera module functions as an imaging unit that captures an image of the front side of the smart device 111 based on an imaging command input from the CPU, and inputs the generated image information to the CPU. The Bluetooth module functions as a short-range wireless communication unit that wirelessly communicates with the locking / unlocking device 20. The speaker functions as a sound output unit that generates sound input from the CPU.

[0024] By executing the authentication application, the CPU executes a process of inputting an imaging command to the camera module, a process of detecting a person from the image input from the camera module, a process of performing face authentication based on the face of the detected person, and a process of transmitting an unlock command to the locking / unlocking device 20 via the Bluetooth module if the face authentication is successful. That is, the CPU functions as a camera control unit that inputs an imaging command to the camera module and controls the camera module, a detection unit that detects a person from the image, an authentication unit that authenticates the detected person, and a locking / unlocking control unit that transmits an unlock command to the locking / unlocking device 20 and controls it.

[0025] The smart device 111 is housed in a housing 112 so that the touch panel display and the camera module are exposed. As shown in Fig. 3, a plurality of screw holes 113 are formed on the rear surface of the housing 112.

[0026] As shown in FIG. 1 and FIG. 3, the installation tool 130 of the door device 100 includes an intervening portion 131, a first extending portion 132, and a second extending portion 133, and each of these components is formed of a metal material. The intervening portion 131 is a portion intervening in the gap S between the door 11 and the frame 12, and is formed in a plate shape with a thickness thinner than the gap S. The intervening portion 131 is disposed along the upper surface 11c of the door 11 and formed in a strip shape extending in the horizontal direction. Specifically, it has the same width as the width of the upper surface 11c (thickness of the door 11) and is formed in a strip shape extending the length of the upper surface 11c (width of the door 11). The first extending portion 132 is connected to the end of the intervening portion 131 located on the outside of the room, and the second extending portion 133 is connected to the end of the intervening portion 131 located on the inside of the room.

[0027] The first extension portion 132 is a portion formed in a band shape extending downward from the upper edge of the door 11, and is disposed along the exterior side surface 11a of the door 11. The upper end of the first extension portion 132 is connected to the intermediate portion 131. The lower end of the first extension portion 132 is located in the middle of the door 11 (near the handle). A plurality of mounting holes 134 are formed in the lower end of the first extension portion 132. Each of the mounting holes 134 is formed at a position corresponding to the screw hole 113 of the housing 112 of the authentication device 110. The authentication device 110 is attached to the first extension portion 132 by screwing a plurality of screws 140 into the screw holes 113 of the authentication device 110 through these mounting holes 134.

[0028] The second extension portion 133 is a plate-like portion disposed along the upper edge of the door 11 and the indoor side surface 11b of the door 11. The thickness of the second extension portion 133 is not particularly limited, but is formed to be the same as the thickness of the intermediate portion 131 in this embodiment.

[0029] In the installation tool 130 configured as described above, a U-shaped portion is formed by the upper portion of the first extension portion 132, the intervening portion 131, and the second extension portion 133. The upper portion of the door 11 fits into the U-shaped portion, and the installation tool 130 is attached to the door 11. The installation tool 130 is attached to the door 11 with the authentication device 110 first attached to the first extension portion 132 and the door 11 open. When the door device 100 is installed on the door 11, the door 11 fits into the U-shaped portion, and the intervening portion 131 is interposed in the gap S between the frame 12 and the door 11, so that the door device 100 cannot be removed when the door is closed. In this way, according to the door device 100 of this embodiment, the authentication device 110 can be installed on the door 10 simply by fitting the door 11 of the door 10 into the installation tool 130. In this way, there is no need for construction such as drilling holes in the existing door 10, and it is possible to easily attach and detach the authentication device 110. In addition, since no construction or processing is required for the existing door 10, there is no need to repair it when a tenant moves out of a rental property, and therefore it can be introduced into existing rental properties.

[0030] In addition, in this embodiment, as an attachment structure for attaching the authentication device 110 to the installation tool 130, the screw hole 113 on the back surface of the housing of the authentication device 110, the attachment hole 134 of the first extension portion 132, and the screw 140 fastened to the screw hole 113 through the attachment hole 134 are adopted, and since the attachment structure is a structure in which the attachment operation is performed on the authentication device 110 from the door 11 side of the first extension portion 132, the authentication device 110 cannot be removed from the installation tool 130 unless the installation tool 130 is removed from the door 11. In other words, since the authentication device 110 cannot be removed when the door device 100 is installed on the door 10, the theft of the authentication device 110 can be prevented.

[0031] [Second embodiment]

[0032] As shown in Fig. 4 and Fig. 5, the door device according to the second embodiment is common to the first embodiment in that it includes an authentication device 110 (not shown) and an installation tool 130a. However, the door device of this embodiment is different from the first embodiment in that the mounting position of the authentication device 110 relative to the installation tool 130a is adjustable. The door device of this embodiment is also different in that the authentication device 110 includes an electric wire, and a groove in which the electric wire can be routed is formed in the installation tool 130a. Below, the configuration of this embodiment that is different from the first embodiment will be mainly described, and a description of the points in common with the first embodiment will be omitted as appropriate.

[0033] The installation tool 130a of this embodiment includes an intervening portion 131a, a first extending portion 132a, and a second extending portion 133a, as in the first embodiment, and the authentication device 110 is attached to the lower end of the first extending portion 132a. As described above, in this embodiment, the position at which the authentication device 110 is attached to the first extending portion 132a can be adjusted. Specifically, a plurality of mounting holes 134 are formed in the lower end of the first extending portion 132a. The number of the plurality of mounting holes 134 is greater than the number of screw holes 113 of the authentication device 110. A screw 140 is screwed into the screw hole 113 of the authentication device 110 through any one of the plurality of mounting holes 134. In this manner, first extending portion 132a of the present embodiment has a plurality of mounting holes 134 formed at its lower end, and the mounting holes 134 are provided at a plurality of locations on first extending portion 132a so as to be equally spaced from the lower end upward, making it possible to adjust the mounting position of authentication device 110. In this manner, the plurality of mounting holes 134 function as an adjustment portion that adjusts the mounting position of authentication device 110.

[0034] As described above, the authentication device 110 of this embodiment includes electric wires. The electric wires include a power supply line for supplying power to the authentication device 110 and / or a communication line for communicating with the authentication device 110, and are connected to a connector of a smart device 111 included in the authentication device 110. In order to wire the electric wires to the indoor side, a groove 135 is formed in the installation tool 130a. Specifically, a groove 135 extending vertically is formed on the back surface of the first extension portion 132a. In addition, a vertically long opening 136 is formed on the lower end of the first extension portion 132a in order to lead the electric wires to the groove 135. The electric wires drawn out to the back side of the first extension portion 132a through the opening 136 are wired to the intermediate portion 131a and the second extension portion 133a while being laid inside the groove 135.

[0035] As shown in Fig. 5, grooves 137, 138 are formed in the intermediate portion 131a and the second extending portion 133a. The groove 137 of the intermediate portion 131a is formed on the lower surface side of the intermediate portion 131a. The groove 138 of the second extending portion 133a is formed on the back surface of the second extending portion 133a. In this way, the electric wires are led into the room while being routed through the grooves 135, 137, 138 on the back side of the installation tool 130a, so that the electric wires can be prevented from being exposed to the outside and damaging the appearance of the door device.

[0036] [Third embodiment]

[0037] As shown in FIG. 6, the door device 100b according to the third embodiment includes an authentication device 110 and an installation tool 130b, as in the first and second embodiments. However, the door device 100b of this embodiment differs from the first and second embodiments in that the intervening portion 131b of the installation tool 130b extends long in the thickness direction of the door 11. Since the intervening portion 131b extends long in the thickness direction of the door 11, a space is formed between the second extending portion 133b and the door 11. Therefore, the installation tool of this embodiment includes a spacer 142 disposed between the second extending portion 133b and the door 11.

[0038] Specifically, a screw hole 143 is formed at the lower end of the second extension portion 133b, and the spacer 142 is fixed to the screw hole 143. The spacer 142 includes a screw shaft portion 142a screwed into the screw hole 143 of the second extension portion, a contact portion 142b provided at the tip of the screw shaft portion 142a and contacting the indoor side surface 11b of the door 11, and a knob portion 142c provided at the rear end of the screw shaft portion 142a. When the knob portion 142c is rotated in the screw tightening direction, the contact portion 142b moves linearly toward the door 11 and contacts the indoor side surface 11b of the door 11. In this way, the contact portion 142b contacts the indoor side surface 11b of the door 11, and the second extension portion 133b is supported by the spacer 142. In this embodiment, the spacers 142 are arranged on the left and right of the lower end of the second extension portion 133b.

[0039] In the door device 100b of this embodiment, the intermediate portion 131b extends long in the thickness direction of the door 11, so that it can be attached to doors 11 of various thicknesses. In addition, since the second extension portion 133b is supported by the spacer 142, the installation tool 130b can be stably attached to the door 11.

[0040] [Fourth embodiment]

[0041] As shown in Figure 7, the installation device 130c provided in the door device 100c of the fourth embodiment includes an upper intervening portion 131c interposed in the gap S between the frame 12 and the door 11 at the upper part of the door 10, a lower intervening portion 144 interposed in the gap S between the frame 12 and the door 11 at the lower part of the door 10, a first extension portion 132c arranged on the outside of the door 11 and extending from the upper intervening portion 131c toward the lower intervening portion 144, a second extension portion 133c arranged on the inside of the door 11 and extending downward from the upper intervening portion 131c, and a third extension portion 145 arranged on the inside of the door 11 and extending upward from the lower intervening portion 144.

[0042] The upper intermediate portion 131c in this embodiment has a similar configuration to the intermediate portion 131 in the first embodiment, but may have a similar configuration to the intermediate portions 131a, 131b in the second or third embodiment. Also, the second extending portion 133c in this embodiment has a similar configuration to the second extending portion 133 in the first embodiment, but may have a similar configuration to the second extending portions 133a, 133b in the second or third embodiment.

[0043] The first extension portion 132c in this embodiment is different from the first embodiment in that it extends from the upper end to the lower end of the door 11, but otherwise has the same configuration as the first embodiment. The first extension portion 132c in this embodiment may be provided with a plurality of mounting holes 134, as in the first extension portion 132a in the second embodiment, so that the mounting position of the recognition device 110 can be adjusted. The first extension portion 132c in this embodiment may be provided with an opening 136 through which the electric wire of the recognition device 110 can be inserted, and a groove 135 may be formed on the back surface thereof, as in the first extension portion 132a in the second embodiment.

[0044] In this embodiment, the lower interposed portion 144 has the same configuration as the upper interposed portion 131c. Moreover, the third extending portion 145 is a form in which the second extending portion 133c is turned upside down.

[0045] [Fifth embodiment]

[0046] As shown in FIG. 8, the installation fixture 130d provided for the door device 100d of the fifth embodiment includes a pair of intervening parts 146, 147 interposed in the gap S between the frame 12 (vertical frame) and the door 11 on both sides of the door 10, a first extension part 132d arranged on the outside of the door 11 and extending left and right between one intervening part 146 and the other intervening part 147, a second extension part 133d arranged on the inside of the door 11 and extending from one intervening part 146 along the indoor side surface 11b of the door 11, and a third extension part 145d extending from the other intervening part 147 along the indoor side surface 11b of the door 11, and these configurations correspond to configurations obtained by rotating each of the configurations of the above-mentioned fourth embodiment.

[0047] Although the embodiment of the present invention has been described above, the present invention is not limited to the above embodiment, and may be modified as follows.

[0048] [Variation 1] The intervening portion, the first extension portion, and the second extension portion are formed by pressing (bending) a single metal plate, but these configurations may also be formed by joining separate metal plates by welding.

[0049] [Variation 2] In the first to third embodiments, the first extension portion extends from the upper edge of the door 11 to a position about the middle of the door 11, but it may also be in a form in which it extends only to the upper part of the door 11.

[0050] [Variation 3] In the first to third embodiments, the second extension portion extends downward from the upper edge of the door 11, but the length of the downward extension is not particularly limited, and it may extend only to the upper part of the door 11, or may extend to a position about halfway up the door 11. The second extension portion may extend to the lower end of the door 11 and be connected to the lower intervening portion 144, similar to the first extension portion 132c in the fourth embodiment.
