[0008] (doors and windows) Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In Figures 1 to 6, 1 is a fitting according to an embodiment of the present invention, and the fitting 1 is applicable to a hotel door, but the fitting 1 of the present invention is not limited to a hotel door and can also be applied to an apartment door, etc.

[0009] 1 to 6, the fitting 1 comprises a door body 2, a frame body 3, a sleeve 4, a locking device 5, an electric opening and closing device (electric opening and closing means) 6, an indoor operation button 7 (locking operation means, automatic opening and closing operation means), a human presence sensor 8, an authentication device (authentication means) 9, and a control unit 10. Incidentally, the human presence sensor 8 is adopted as an optional specification that can be attached if requested by the user, and may or may not be provided.

[0010] (Door body) The door body 2 of this embodiment is a hinged door. The door body 2 of this embodiment, which is applied to a hotel door, is opened and closed by rotating toward the inside of the room around a hinge 21. The door body 2 applied to an apartment door is opened and closed by rotating toward the outside of the room. Furthermore, the door body 2 of the present invention is not limited to a hinged door, but can also be applied to various types of door bodies such as a sliding door or a folding door. Furthermore, when the door body 2 is a hinged door, the opening and closing direction is not limited to the outside of the room as in this embodiment, but may of course be toward the inside of the room.

[0011] As shown in Figure 1, the exterior surface of the door body 2 has a flat surface with no protrusions. This type of door body 2 reduces design restrictions imposed by protrusions such as doorknobs, and increases the freedom of exterior design. Furthermore, the door body 2 of this embodiment is a hinged door that opens toward the interior, and when unlocked, it can be opened by pushing the exterior surface, so there is no problem even if the exterior surface is flat.

[0012] On the other hand, as shown in Figures 2 and 3, the indoor surface (opening surface) of the door body 2 is provided with a handle 22 that does not protrude from the surface. For example, the door body 2 of this embodiment has a recess 23 recessed inside the door body 2, and by inserting a hand into this recess 23 and engaging the handle 22 from the inside, the door body 2 can be pulled toward you. In other words, in the unlocked state, the door body 2 can be opened by engaging the handle 22 and pulling it toward you. With such a door body 2, manual opening and closing operations are possible without forming protrusions on the outdoor and indoor surfaces.

[0013] (Frame) As shown in Figures 1 to 4, the frame body 3 is composed of an upper frame 31, a lower frame 32, a vertical frame 33 on the trailing edge side, and a vertical frame 34 on the leading edge side. The door body 2 is disposed on the inner periphery of the frame body 3 and is supported by the vertical frame 33 on the trailing edge side via hinges 21 so as to be able to open and close.

[0014] (sleeve) As shown in FIGS. 1 to 3 and 5, the sleeve portion 4 includes a sleeve portion frame 41 and a sleeve panel .

[0015] The sleeve frame 41 is composed of an upper sleeve frame 41a aligned in series with the upper frame 31 of the frame body 3, a lower sleeve frame 41b aligned in series with the lower frame 32 of the frame body 3, one vertical sleeve frame 41c aligned along the vertical frame 34 on the door end side of the frame body 3, and the other vertical sleeve frame 41d aligned parallel to and spaced apart from the one vertical sleeve frame 41c. The indoor side of the sleeve frame 41 is preferably closed with a panel (not shown).

[0016] The sleeve panel 42 is arranged on the inner periphery of the sleeve frame 41 so as to be aligned to the side of the exterior surface of the door body 2. In this embodiment, the sleeve panel 42 is supported on the sleeve frame 41 via upper and lower pivot shafts 43, 44 so as to be openable and closable, but it may also have a support structure that prevents it from being opened and closed. Normally, the opening and closing of the sleeve panel 42 is restricted by a fixing screw 45, and the opening and closing of the sleeve panel 42 is permitted by removing the fixing screw 45.

[0017] The sleeve panel 42 has a flat surface on the outdoor side, with a rectangular opening 42a formed in the surface. An authentication device 9 is disposed in the opening 42a of the sleeve panel 42. The authentication device 9 is visible from the outdoor side through the opening 42a, but does not protrude from the opening 42a to the outdoor side.

[0018] A permeable sheet 46 is provided on the surface of the sleeve panel 42 facing the outdoor side, and at least a portion of the authentication device 9 is covered with the permeable sheet 46. The permeable sheet 46 is, for example, a colored sheet member with a design such as a wood grain pattern, and for example, the entire authentication device 9 is covered with the permeable sheet 46. In this configuration, during normal times when the authentication device 9 is not activated, the authentication device 9 is concealed by the permeable sheet 46 and is not directly visible. Incidentally, if the permeable sheet 46 is not provided, the authentication device 9 would be visible even during normal times when the authentication device 9 is not activated.

[0019] Even if the transparent sheet 46 covers the entire authentication device 9, when the authentication device 9 is activated, the display content of the authentication device 9 (for example, the display content of a backlit LCD panel) can be seen from outside the room, and the transparent sheet 46 has the property of allowing operation of the touch panel of the authentication device 9 from outside the room. This allows the authentication device 9 to be concealed under normal circumstances, but allows light to pass through during authentication, making it possible for authentication by the authentication device 9 to be performed appropriately. Incidentally, the light-transmitting performance of the transparent sheet 46 varies depending on the function, such as whether it has enough light transmittance to allow the camera of the authentication device 9 to photograph the outside of the room, or whether it does not have this function. It goes without saying that the necessary transparent sheet 46 can be selected and used as appropriate from among the transparent sheets 46 having such functions.

[0020] (locking device) The locking device 5 is an electric or electronic type, and locks and unlocks the door body 2 in response to a signal from the control unit 10. For example, the locking device 5 of this embodiment is composed of a locking device main body 51 provided in the vertical frame 34 on the door end side, and a strike 52 provided at the door end of the door body 2, and the door body 2 is locked when the locking device main body 51 projects a deadbolt (not shown) into the strike 52.

[0021] (Electric switchgear) The electric opening and closing device 6 electrically (automatically) opens and closes the door body 2 in response to a signal from the control unit 10. For example, the electric opening and closing device 6 of this embodiment is composed of an electric door closer consisting of an electric door closer main body 61 provided on the upper part of the interior surface of the door body 2, and an arm mechanism (not shown) extending from the electric door closer main body 61 and connected to the upper frame 31.

[0022] (Indoor operation button) The indoor operation button 7 is provided on the indoor side and functions as an operating tool for the locking device 5 and the electric opening and closing device 6. In this embodiment, the indoor operation button 7 is provided on the indoor surface of the vertical frame 34 on the door end side, but the indoor operation button 7 may also be provided on the indoor surface of the door body 2 or on the indoor surface of a sleeve section (not shown). The indoor operation button 7 functions as an operating tool for the locking device 5 and the electric opening and closing device 6 on the indoor side, and various sensors can be used to replace this function, such as a touch sensor that detects contact with an object such as a finger and is activated, a photoelectric sensor that is activated by blocking the light source between the emitter and receiver, and a proximity sensor that is activated by detecting the proximity of an object such as a finger.When such a sensor is used, it can be installed in an appropriate position (location) as needed, and it can also be configured to automatically open when detected by the installed sensor.

[0023] (Humanity sensor) The human presence sensor 8 detects people outside the room and transmits a human detection signal to the control unit 10. When the human presence sensor 8 is provided, it is built into the sleeve section 4 (sleeve panel 42) and detects hotel guests outside the room. The human presence sensor 8 can be an infrared type, an ultrasonic type, or the like, but it is also possible to take a picture of the outside room with a camera and detect hotel guests based on the captured image.

[0024] (Authentication device) The authentication device 9 is activated when the display unit is touched with an object such as a finger, and a screen display appears. The authentication device 9 then authenticates the key means in response to the screen activation. If the key means is approved, the authentication device 9 sends an approval signal to the control unit 10 to unlock the locking device 5 and open the electric opening / closing device 6. For example, the authentication device 9 of this embodiment includes a display unit (not shown) made of a backlit LCD panel visible from the outside of the room through the opening in the sleeve panel 42, a touch panel (not shown) superimposed on the display unit, a camera (not shown) that captures images of the outside of the room through the opening in the sleeve panel 42, and an authentication control unit (not shown) that controls these to authenticate the key means. Such an authentication device 9 may be configured by installing a dedicated application on a general-purpose device such as a tablet or smartphone.

[0025] The key means may be a two-dimensional code (QR Code (registered trademark), etc.), biometrics (fingerprint, face, etc.), passcode, card key, etc., and in this embodiment, authentication is performed using a two-dimensional code as the key means. For example, a hotel guest obtains a two-dimensional code for the room they will be using when checking in. The two-dimensional code may be read by the hotel guest's smartphone, or may be provided to the hotel guest on paper or card media.

[0026] For example, when the authentication device 9 is started, it displays an authentication start button on the display unit, and displays a two-dimensional code reading screen in response to a touch operation of the authentication start button. Here, when a hotel guest presents a two-dimensional code to the authentication device 9, the authentication device 9 authenticates the two-dimensional code while displaying the two-dimensional code photographed by a camera on the display unit. When the authentication device 9 recognizes the two-dimensional code, it displays an authentication success screen on the display unit and transmits an recognition signal to the control unit 10. Furthermore, when authentication of the two-dimensional code fails, the authentication device 9 displays an authentication failure screen on the display unit, and returns to the two-dimensional code reading screen after a predetermined time.

[0027] The display unit (screen) of the authentication device 9 can be used for purposes other than authentication by displaying pictures, letters, symbols, marks, etc. For example, when the door body 2 opens or closes automatically, a warning message such as "The door will open and close automatically" can be displayed on the display unit of the authentication device 9 to alert hotel guests. In addition, in the event of a disaster such as a fire or earthquake, evacuation guidance can be provided by displaying arrows indicating the evacuation direction on the display unit of the authentication device 9. Furthermore, if messages to be communicated to hotel staff (such as "Please do not disturb me" or "Please clean the room") are displayed on the display unit of the authentication device 9, a door sign plate that can be hung on the door handle becomes unnecessary. Furthermore, abnormalities in the room can be displayed on the display unit of the authentication device 9.

[0028] (control unit) 6, the control unit 10 is connected to a locking device 5, an electric opening and closing device 6, an indoor operation button 7, a human sensor 8, and an authentication device 9. The connections may be wired or may be made via wireless communication.

[0029] The control unit 10 activates the authentication device 9 when it receives an activation signal resulting from touching the display unit of the authentication device 9 or a human detection signal from the human sensor 8. Furthermore, when the control unit 10 receives an approval signal from the authentication device 9, for example, as a result of authenticating a camera image, it causes the locking device 5 to unlock and then opens the electric opening and closing device 6. This allows the hotel guest to enter the room by simply performing a predetermined authentication operation on the authentication device 9 from outside the room, and the door body 2 automatically opens.

[0030] After that, when a predetermined time has elapsed, the control unit 10 causes the electric opening and closing device 6 to perform a closing operation to automatically close the door body 2, and also causes the locking device 5 to perform a locking operation to put the door body 2 in a locked state.

[0031] Furthermore, when the control unit 10 receives an operation signal from the indoor operation button 7, it unlocks the locking device 5 and then opens the electric opening and closing device 6. This allows hotel guests to simply operate the indoor operation button 7, which automatically opens the door body 2 and allows them to leave the room.

[0032] After that, when a predetermined time has elapsed, the control unit 10 causes the electric opening and closing device 6 to perform a closing operation to automatically close the door body 2, and also causes the locking device 5 to perform a locking operation to put the door body 2 in a locked state.

[0033] According to this embodiment configured as described above, the fitting 1 comprises a door body 2, a frame body 3 that supports the door body 2 so that it can be opened and closed, a sleeve panel 42 that is provided on the frame body 3 side so as to be aligned with the side of the exterior face of the door body 2, and an electric or electronic locking device 5 that locks and unlocks the door body 2. Since the door body 2 has a flat surface on at least one of the exterior face and the interior face with no protrusions, and the sleeve panel 42 has a flat surface on the exterior face, design restrictions due to protrusions such as doorknobs are reduced, and the freedom of exterior design can be increased.

[0034] In addition, the fixture 1 is equipped with an authentication device 9 that authenticates the key means in response to the activation of the screen, and unlocks the locking device 5 upon approval of the key means, thereby enabling smooth unlocking operations using the key means.

[0035] Furthermore, the sleeve panel 42 has an opening on its flat surface facing the outside of the room, and the authentication device 9 is provided in this opening, so that the authentication device 9 can be placed without impairing the design of the sleeve panel 42.

[0036] In addition, a transparent sheet 46 is provided on the surface of the sleeve panel 42, and at least a portion of the authentication device 9 is covered with the transparent sheet 46, so that at least a portion of the authentication device 9 is concealed under normal circumstances, but light is transmitted during authentication, allowing authentication by the authentication device 9 to be performed appropriately.

[0037] Furthermore, the door body 2 is a hinged door, and a handle 22 that does not protrude from the surface is provided on the surface of the open side of the door body 2, so that the door body 2 can be opened without providing a protrusion on the surface of the open side of the door body 2.

[0038] In addition, an indoor operation button 7 that can operate the locking device 5 is provided on the indoor surface of the frame body 3, so that the door body 2 can be locked and unlocked by operating it from the indoor side.

[0039] In addition, the fixture 1 further includes an electric opening and closing device 6 that automatically opens and closes the door body 2, and when the authentication device 9 approves the key means, it automatically opens and closes the door body 2, eliminating the need for manual opening and closing of the door body 2.

[0040] In addition, an indoor operation button 7 that can operate the electric opening and closing device 6 is provided on the indoor surface of the frame body 3, so that the door body 2 can be automatically opened and closed by operating it from the indoor side.

[0041] Furthermore, the display unit of the authentication device 9 can display pictures, letters, symbols, marks, etc., and can be used, for example, to display warnings when the door body 2 automatically opens and closes, to display evacuation guidance in the event of a disaster, to display door sign plates in hotels, and to display abnormalities in the room. Incidentally, the authentication device 9 is capable of displaying various types of information on the display unit, such as the warning information, evacuation guidance information, door sign plate information, and abnormality information, as mentioned above. However, the authentication device 9 may be provided with a built-in audio generating means in addition to or instead of such information so that various notifications can be made by audio.

[0042] Of course, the present invention is not limited to the above-described embodiment, and for example, as in the second embodiment shown in Fig. 7 as a control unit, the control unit 10 is connected to the locking device 5 and the authentication device 9, and the locking device 5 is connected to the motion sensor 8, the indoor operation button 7, and the electric opening and closing device 6. Then, when the authentication device 9 is activated, the control unit 10 outputs an unlock signal to the locking device 5 if authentication is confirmed by the authentication device 9 or if there is a signal from the motion sensor 8 or the indoor operation button 7, and further, the locking device 9 that has received the unlock signal can be configured to output an open command to the electric opening and closing device 6.
