Description

Building materials

[0001] The present disclosure relates to building materials.

[0002] Doors with fire-resistant certification specifications are known in the art. Fire-resistant certified doors are required to have flame-blocking performance that prevents flames from spreading to the unheated side (outside the room) for a certain period of time in the event of a fire.

[0003] Japanese Patent Application Laid-Open No. 2007-146586

[0004] In the event of a fire, the pressure difference between the inside and outside of the door may exert a force in the opening direction. If the door is locked, it will remain in the closed position, preventing flames from spreading to the unheated side (either the inside or the outside of the room). However, if the door is unlocked due to reasons such as forgetting to lock it, the pressure difference between the inside and the outside of the room may cause the door to open, even if the door is in the closed position, and flames may spread to the unheated side (either the inside or the outside of the room). In particular, if the latch mechanism used to hold the door in the closed position is a roller latch or other device with weak holding power, the risk of the door opening in the event of a fire increases.

[0005] The present disclosure aims to provide a fixture that can reliably keep a door locked when in the closed position.

[0006] The present disclosure relates to a fixture comprising: an openable and closable door body provided at an opening in a building; an electric lock for locking and unlocking the door body; a control unit for controlling the locking and unlocking operation of the electric lock so that it automatically locks after unlocking; and a power supply path for supplying power to the electric lock via the control unit, wherein the power supply path includes at least a first power supply path connected to a regular power source and a second power supply path connected to a backup power source.

FIG. 2 is a perspective view showing a state in which the door body of the fitting of an embodiment is positioned in the open position. FIG. 3 is a perspective view showing the surface of the sleeve portion facing the door body. FIG. 4 is a perspective view showing a lock receiving portion and a latch receiving portion provided on the door body. FIG. 5 is a diagram showing how a roller latch engages with the latch receiving portion. FIG. 6 is a diagram showing a schematic configuration of an electric lock system in a fitting of an embodiment. FIG. 7 is a flowchart showing an example of the operation of an electric lock system in a fitting of an embodiment. FIG. 8 is a diagram showing a schematic configuration of an electric lock system in a fitting of another embodiment.

[0008] An embodiment of the fittings of the present disclosure will be described in detail below with reference to the drawings. In the following description, the lateral direction of the door body 3 and the sleeve portion 4 is referred to as the left-right direction X. The left-right direction X is the width direction of the door body 3 and the sleeve portion 4. In the left-right direction X, one side is defined as X1 (the right side in FIG. 1 ), and the other side is defined as X2 (the left side in FIG. 1 ).

[0009] 1 and 2, the fitting 1 of this embodiment comprises a frame 2 fixed to an opening in a building, a door body 3 (door body) arranged so as to be able to open and close within the frame 2, and a sleeve 4 arranged on the door end side of the frame 2. The fitting 1 is installed as an entrance to a building. The fitting 1 locks and unlocks the door body 3 using an electric lock 5.

[0010] The frame body 2 is provided along the four periphery of the opening of the building. As shown in Figures 1 and 2, the frame body 2 is framed in a rectangular shape by an upper frame 21 and a lower frame 22 as horizontal frames, a vertical frame 23 arranged on one side X1 in the left-right direction X, and a vertical frame 24 arranged on the other side X2 in the left-right direction X. Within the frame body 2, a door body 3 and a sleeve 4 are arranged adjacent to each other in the width direction. The door body 3 is arranged on one side X1 in the left-right direction X. The sleeve 4 is arranged on the other side X2 in the left-right direction X.

[0011] The door body 3 is a front door. The door body 3 is heavier and more substantial than an interior door body. The door body 3 is a swing door that can be opened and closed by rotating around the rotation axis of a hinge 25 provided on a vertical frame 23 on one side X1 in the left-right direction X. The door body 3 is installed in a so-called outward-opening state, which means that it rotates from a closed state toward the outside of the room.

[0012] The door body 3 is formed in the shape of a generally rectangular plate that is long in the vertical direction. As shown in Figure 2, an exterior handle 26 is attached to the exterior surface of the door body 3. An interior handle 27 is attached to the interior surface of the door body 3. The exterior handle 26 and the interior handle 27 are formed to extend in the vertical direction near the end of the door tip side (the other side X2) of the door body 3.

[0013] The exterior handle 26 and the interior handle 27 are formed in a generally U-shape with an opening on the side of the door body 3. The upper and lower ends of the exterior handle 26 and the interior handle 27 are connected to the exterior or interior surface of the door body 3.

[0014] The exterior handle 26 and the interior handle 27 constitute gripping portions that are gripped by a user who opens or closes the door body 3. When the user pushes or pulls the door body 3 to open or close the door body 3, the user grips the exterior handle 26 or the interior handle 27.

[0015] The exterior handle 26 and the interior handle 27 are fixed handles that are immovably fixed to the door body 3. The exterior handle 26 and the interior handle 27 are fixed to the exterior or interior surface of the door body 3 in a manner that does not move relative to the door body 3 so that the door body 3 can be opened and closed. The exterior handle 26 and the interior handle 27 are not provided with a mechanism for releasing the roller latch 7 (latch portion). For example, conventional fittings have been known that have a mechanism that can release the latch portion in conjunction with the handle. In contrast, neither the exterior handle 26 nor the interior handle 27 has a mechanism for releasing the latch portion in conjunction with the handle. Therefore, in the fitting 1 of this embodiment, the roller latch 7 (latch portion) cannot be released even if a user pushes or pulls the exterior handle 26 or the interior handle 27.

[0016] 2, the exterior handle 26 has a grip bar 261 (vertical member) extending in the vertical direction, and a pair of end support portions 262 protruding from the upper and lower ends of the grip bar 261 toward the door body 3. The grip bar 261 is grasped when opening or closing the door body 3 from the exterior side.

[0017] Similar to the configuration of the exterior handle 26, the interior handle 27 has a grip bar 271 (vertical member) extending in the vertical direction and a pair of end support portions (not shown) protruding from the upper and lower ends of the grip bar 271 toward the door body 3. The grip bar 271 is grasped when opening or closing the door body 3 from the interior side.

[0018] In this embodiment, the grip bar 261 of the exterior handle 26 and the grip bar 271 of the interior handle 27 are formed in a straight line extending vertically, for example, with a length of 80% to 100% of the vertical length of the door body 3, when viewed from inside or outside the room.

[0019] 1 and 2, the sleeve portion 4 is disposed adjacent to the door body 3 within the frame 2. When the door body 3 is in the closed position, the sleeve portion 4 is disposed on the door leading side (the other side X2) of the door body 3. When the door body 3 is in the closed position, the sleeve portion 4 is disposed opposite the end face 3a of the door body 3 on the door leading side.

[0020] The sleeve 4 is a sub-door that can be opened and closed by rotating around the rotation axis of a hinge 41 provided on the vertical frame 24 on the other side X2 in the left-right direction X. The sleeve 4 is installed in a so-called outward-opening manner, rotating from a closed state toward the outside of the room (the front side of the paper in Figure 1). The sleeve 4 is normally fixed in a closed state. The sleeve 4 is used in an open state when it is necessary to widen the opening inside the frame body 2 to load or unload large items, such as when moving.

[0021] The sleeve portion 4 is provided with two electric locks 5, an authentication unit 6, and a roller latch 7 (latch unit). The two electric locks 5 are provided spaced apart above and below the sleeve portion 4. As shown in Figure 1, the electric locks 5 and the authentication unit 6 are configured to be operable by power supplied from a regular power supply unit 9 via a control unit 8.

[0022] As shown in Figure 3, each electric lock 5 comprises a box lock portion 51 having a hook-shaped dead sickle portion 511, a cylinder portion 52 having a keyhole 521 formed at the tip, and a thumb turn portion (not shown).

[0023] The box lock unit 51, cylinder unit 52, and thumb turn unit (not shown) are provided in the sleeve unit 4. The cylinder unit 52 is provided on the outdoor side of the sleeve unit 4. The thumb turn unit, not shown, is provided on the indoor side of the sleeve unit 4. The box lock unit 51 is used both when locking and unlocking electrically and when locking and unlocking manually.

[0024] The dead sickle portion 511 is provided so as to be able to protrude from the end surface 4a of the sleeve portion 4 toward the door body 3. The dead sickle portion 511 is formed in a sickle shape with the tip protruding upward when locked. The dead sickle portion 511 is able to engage with the lock receiving portion 28 (see Figures 2 and 4) provided on the end surface 3a on the door leading side of the door body 3.

[0025] The dead sickle portion 511 is configured to be movable between a protruding position where it engages with the lock receiving portion 28 of the door body 3 to lock it and a retracted position where it disengages from the lock receiving portion 28 and unlocks it, driven by a motor (not shown) provided in the box lock portion 51. The dead sickle portion 511 is configured to be movable between the protruding position and the retracted position by a user opening or closing the door body 3 by rotating the keyhole 521 of the cylinder portion 52 from the outside of the room or by rotating a thumb turn portion (not shown) from the inside of the room. The dead sickle portion 511 is also configured to be movable by operating a portable authentication device, card key, or the like carried by the user, as will be described later.

[0026] As shown in Figures 1 and 2, the authentication unit 6 is provided in the sleeve section 4. The authentication unit 6 includes an authentication function unit 61. As shown in Figure 1, the authentication function unit 61 is exposed and located on the exterior side of the sleeve section 4. The authentication function unit 61 has an authentication button. When a user brings a portable authentication device and presses the authentication button on the authentication function unit 61, or when a user presses the authentication button on the authentication function unit 61 and holds up an authentication card key, the authentication unit 6 wirelessly receives authentication signals from the portable authentication device and card key to authenticate the user. When the authentication unit 6 authenticates the user, it transmits the authentication signal to the control unit 8. The control unit 8 interprets the authentication signal transmitted from the authentication unit 6 and, if certain conditions are met, drives the motor (not shown) of the electric lock 5. This moves the dead sickle portion 511 of the box lock unit 51 to the storage position, unlocking the door body 3. When the door body 3 is unlocked, the user can open or close the door body 3 by grasping the exterior handle 26 or the interior handle 27 and pushing or pulling the door body 3.

[0027] As shown in FIG. 3, the roller latch 7 is disposed at the end of the sleeve 4 on the door body 3 side, between two electric locks 5 disposed apart in the vertical direction.

[0028] The roller latch 7 is a latch that does not interlock with the exterior handle 26 or the interior handle 27. The exterior handle 26 and the interior handle 27 are not provided with a mechanism for releasing the latch. Because the roller latch 7 is not interlocked with the exterior handle 26 or the interior handle 27, the exterior handle 26 or the interior handle 27 cannot release the roller latch 7 when the door body 3 is in the closed position. For example, the roller latch 7 will not be released just by a user gripping the exterior handle 26 or the interior handle 27.

[0029] As shown in Figures 3 and 5, the roller latch 7 has a cylindrical roller portion 71 that extends in the vertical direction. The roller portion 71 is rotatable around a rotation shaft 72 that extends in the vertical direction. The roller portion 71 is provided on the end surface 4a of the sleeve portion 4 in a state where it is biased toward the door body 3. The end surface 4a of the sleeve portion 4 is the surface that faces the end surface 3a on the door leading side of the door body 3 when it is in the closed position. The roller portion 71 is provided so as to be able to protrude from the end surface 4a of the sleeve portion 4 toward the door body 3.

[0030] When the door body 3 is closed, the roller portion 71 is biased to protrude toward the door body 3. A latch receiving portion 29 (see FIGS. 2 and 4) is provided on the leading end surface 3a of the door body 3. The roller portion 71 protruding toward the door body 3 engages with the latch receiving portion 29 (see FIGS. 2 and 4) to hold the door body 3 in a closed state. In this state, when a user applies a force to the door body 3 that is greater than the force with which the roller portion 71 holds the door body 3, the engagement of the roller portion 71 is released, allowing the door body 3 to be opened. As shown in FIGS. 4 and 5, the latch receiving portion 29 is formed as a semicircular recess from the leading end surface 3a of the door body 3 and extends in the vertical direction.

[0031] When opening the door body 3 from the exterior side, after unlocking it with the electric lock 5 from the state shown in Fig. 1, the exterior handle 26 is pulled toward the user. When a force greater than the force holding the door body 3 is applied to the door body 3, the roller latch 7 disengages from the latch receiver 29, and the door body 3 opens as shown in Fig. 2. When closing the door body 3, as shown in Fig. 5, the door body 3 is moved to the closed position, and the roller latch 7 engages with the latch receiver 29. This closes the door body 3. As will be described later, after the door body 3 is closed, the door body 3 is automatically locked by the electric lock 5.

[0032] As shown in Fig. 1, the fixture 1 further comprises a control unit 8 that controls various electrical operations of the fixture 1, a normal power supply unit 9 that receives power from a normal power supply, a standby power supply unit 10 that constitutes a standby power supply, and a door detection unit 11 that detects the door body 3 that is placed in the closed position. As shown in Fig. 6, the electric lock system is made up of the electric lock 5, authentication unit 6, control unit 8, normal power supply unit 9, standby power supply unit 10, and door detection unit 11.

[0033] The control unit 8, the backup power supply unit 10, and the door detection unit 11 are arranged inside the sleeve 4. The control unit 8 and the backup power supply unit 10 may be arranged inside the exterior wall W of the building. The control unit 8 and the backup power supply unit 10 may be arranged inside or outside the building. The normal power supply unit 9 is arranged inside the exterior wall W to the side of the door fixture 1. The normal power supply unit 9 may be arranged inside or outside the building.

[0034] The control unit 8 and the regular power supply unit 9 are electrically connected by a first wiring L1. The control unit 8 and the backup power supply unit 10 are electrically connected by a second wiring L2. The control unit 8 and the electric lock 5 are electrically connected by a third wiring L3. This allows the control unit 8 to supply power supplied from the regular power supply unit 9 via the first wiring L1 or power supplied from the backup power supply unit 10 via the second wiring L2 to the electric lock 5 via the third wiring L3.

[0035] The first wiring L1, the second wiring L2, and the third wiring L3 form a power supply path that supplies power to the electric lock 5. In this power supply path, the first wiring L1 and the third wiring L3 form a first power supply path connected to a normal power source, and the second wiring L2 and the third wiring L3 form a second power supply path connected to a backup power source.

[0036] The control unit 8 and the authentication unit 6 are electrically connected by a fourth wire L4. The control unit 8 and the door detection unit 11 are electrically connected by a fifth wire L5. This allows the authentication unit 6 and the door detection unit 11 to be supplied with power necessary for their operation via the control unit 8. The control unit 8 receives an authentication signal from the authentication unit 6 via the fourth wire L4 and a detection signal from the door detection unit 11 via the fifth wire L5.

[0037] As shown in Fig. 6, the utility power supply unit 9 includes a plug 91 and a converter 92. The utility power supply unit 9 receives power from a utility power source via the plug 91. The utility power source may be, for example, a 100V commercial power source for home use. The converter 92 converts the 100V AC current supplied via the plug 91 into a DC current of a voltage required for the operation of the electric lock 5, authentication unit 6, control unit 8, and door detection unit 11. The DC current converted by the converter 92 is supplied to the control unit 8 via a first wiring L1.

[0038] As shown in FIG. 6 , the standby power supply unit 10 includes a plug 101 and a power storage device 102. The power storage device 102 has a medium capable of storing and discharging electricity, such as a lithium-ion battery. The power storage device 102 is configured to normally receive and store power from a utility power source via the plug 101. The power storage device 102 may also normally receive and store power from a power generation device (not shown), such as a solar panel or a wind power generation device, installed outside the building. In the event of a power outage in which the utility power source is cut off, the power storage device 102 functions as a standby power supply that supplies direct current by discharging. The direct current from the power storage device 102 is supplied to the control unit 8 via a second line L2.

[0039] As shown in Fig. 6, the control unit 8 has a switching unit 81. In the control unit 8, the first wiring L1, the second wiring L2, and the third wiring L3 are electrically connected to the switching unit 81. The switching unit 81 has a function of switching the power supply path to the electric lock 5 to power supply from the standby power supply unit 10 when power supply from the normal power supply unit 9 is stopped due to a power outage or the like. When power supply from the normal power supply is stopped, the switching unit 81 switches the power supply path to the electric lock 5 from the first power supply path formed by the first wiring L1 and the third wiring L3 to the second power supply path formed by the second wiring L2 and the third wiring L3.

[0040] The switching unit 81 has a transformer unit 81a. The transformer unit 81a transforms the DC current from the standby power supply unit 10 that is input to the switching unit 81. The transformer unit 81a converts the DC current from the standby power supply unit 10 into a voltage required for the operation of the electric lock 5, authentication unit 6, and door detection unit 11. The transformer unit 81a increases or decreases the voltage of the DC current from the standby power supply unit 10 to a voltage required for the operation of the electric lock 5, authentication unit 6, and door detection unit 11.

[0041] The door detection unit 11 is composed of a sensor that detects the door body 3 when it is in the closed position. Specifically, the door detection unit 11 is composed of a non-contact sensor such as a photoelectric sensor that can detect the door body 3 when it is in the closed position, or a contact sensor such as a limit switch. As shown in Figures 1 and 2, the door detection unit 11 is provided inside the sleeve 4. The door detection unit 11 may be provided on the upper frame 21, the lower frame 22, or the vertical frame 23 on the X1 side of the door body 3 in the left-right direction X.

[0042] The door detection unit 11 of this embodiment is configured with a non-contact sensor. As shown in FIG. 3 , the door detection unit 11 has a detection function unit 11a, which is a sensor surface exposed on the end surface 4a of the sleeve portion 4. When the door body 3 is in the closed position and the end surface 3a of the door body 3 on the door leading side is positioned opposite the end surface 4a of the sleeve portion 4, the detection function unit 11a detects the end surface 3a of the door body 3 and transmits a detection signal to the control unit 8. When the door body 3 is open, the detection function unit 11a does not detect the end surface 3a of the door body 3, and therefore the door detection unit 11 does not transmit a detection signal to the control unit 8.

[0043] The control unit 8 is configured with a processor that controls the locking and unlocking operations of the electric lock 5 according to a predetermined program. The control unit 8 controls the locking and unlocking operations of the electric lock 5 using the function of the processor so that the electric lock 5 automatically locks after being unlocked. The control unit 8 uses the function of the processor to determine whether a detection signal is input from the door detection unit 11 and to determine whether the door main body 3 is open or positioned in the closed position. When a detection signal is input from the door detection unit 11 after the door main body 3 has been opened by the unlocking operation of the electric lock 5, the control unit 8 uses the function of the processor to determine that the door main body 3 has been closed and positioned in the closed position, and then causes the electric lock 5 to lock and automatically lock the door main body 3.

[0044] Next, the operation of the fitting 1 will be described with reference to the flowchart shown in Fig. 7. Normally, AC current is supplied to the fitting 1 from the utility power source via the plug 91 of the utility power supply unit 9.

[0045] While AC current is being supplied from the normal power supply unit 9 (step S1; NO), the control unit 8 continues normal operation of controlling the power supply to the electric lock 5 using the first power supply path formed by the first wiring L1 and the third wiring L3 based on signals sent from the authentication unit 6 and the door detection unit 11, and controlling the locking and unlocking operation of the door body 3 (step S2).

[0046] While normal operation continues, the control unit 8 continues to monitor in step S1 whether or not power is being supplied from the normal power supply unit 9. If power supply from the normal power supply is stopped due to a fire or the like while normal operation is being performed, the control unit 8 detects in the switching unit 81 that the supply of DC current from the normal power supply unit 9 has stopped (step S1; YES).

[0047] When the power supply from the normal power source is stopped, the control unit 8 switches the power supply path for supplying power to the electric lock 5 from the first power supply path formed by the first wiring L1 and the third wiring L3 to the second power supply path formed by the second wiring L2 and the third wiring L3 using the switching unit 81 (step S3).

[0048] After the power supply path is switched from the normal power source to the standby power source, the control unit 8 determines whether the electric lock 5 is in the unlocking operation state (step S4). If the control unit 8 determines that the electric lock 5 is not in the unlocking operation state (step S4; NO), the door body 3 is locked and held in the closed position, so the door body 3 will not open due to the pressure difference between the inside and outside of the room caused by a fire, and the flame-blocking performance of the fitting 1 will be maintained.

[0049] After the power supply path is switched from the normal power source to the standby power source, if the control unit 8 determines that the electric lock 5 is in an unlocking operation state (step S4; YES), it determines that there is a possibility that the door body 3 is open. Therefore, the control unit 8 determines whether the door body 3 is closed or not based on the presence or absence of an input of a detection signal from the door detection unit 11 (step S5).

[0050] When the door body 3 is closed by a user, the door detection unit 11 detects the door body 3 in the closed position and transmits a detection signal to the control unit 8. The control unit 8 determines that the door body 3 is closed based on the detection signal from the door detection unit 11 (step S5; YES). The control unit 8 then supplies power from the backup power supply unit 10 to the electric lock 5 via the second power supply path, causing the electric lock 5 to lock (step S6). As a result, the door body 3 is locked and held in the closed position, so that the door body 3 will not open due to a pressure difference between the inside and outside of the room caused by a fire, and the flame-blocking performance of the fitting 1 is maintained.

[0051] In the above embodiment, the power storage device 102 of the standby power supply unit 10 provided in the fixture 1 is used as the standby power supply that supplies DC current to the electric lock 5 via the second power supply path, but the standby power supply may also be a portable external power supply 13, as shown in Fig. 8. In this case, the second power supply path has a standby power supply power port 12 for supplying power from the portable external power supply 13. In Fig. 8, parts with the same reference numerals as in Figs. 1 and 6 indicate parts with the same configuration, and therefore the above explanations are used to refer to those parts, and their explanations will be omitted below.

[0052] Backup power supply inlet 12 is configured to be connectable to portable external power supply 13 via cable 13a. Backup power supply inlet 12 is configured to be able to supply power from portable external power supply 13 to the second power supply path via cable 13a. As portable external power supply 13, a mobile battery, a mobile terminal such as a smartphone or a tablet terminal, a hand-crank generator, a portable solar panel, etc. can be used. Backup power supply inlet 12 may also be configured to be able to supply power wirelessly from portable external power supply 13.

[0053] The backup power supply feed port 12 and the portable external power supply 13 may be arranged inside the sleeve 4, on the outdoor side or indoor side of the sleeve 4, or inside the exterior wall W of the building, on the outdoor side of the exterior wall W, or inside the building. The backup power supply feed port 12 and the portable external power supply 13 may be provided in the building fixture 1 together with the backup power supply unit 10.

[0054] According to this embodiment, the following effects are achieved.

[0055] (1) A fixture 1 includes a door body 3 that can be opened and closed and is installed at an opening in a building, an electric lock 5 that locks and unlocks the door body 3, a control unit 8 that controls the locking and unlocking operation of the electric lock 5 so that it automatically locks after unlocking, and a power supply path that supplies power to the electric lock 5 via the control unit 8, wherein the power supply path includes at least a first power supply path (first wiring L1 and third wiring L3) that is connected to a regular power source and a second power supply path (second wiring L2 and third wiring L3) that is connected to a backup power source.

[0056] According to the above (1), the door body 3 can be reliably kept locked when it is in the closed position. Since the door body 3 will not remain unlocked due to a user forgetting to lock the door, security is improved and the flame-blocking performance of the door body 3 in the event of a fire is maintained.

[0057] (2) The fixture 1 described in (1) above has a switching unit 81 that switches the power supply path from the first power supply path (the first wiring L1 and the third wiring L3) to the second power supply path (the second wiring L2 and the third wiring L3) when the power supply from the normal power source is stopped.

[0058] According to (2) above, if the power supply from the normal power source is stopped, the power supply path can be switched to the second power supply path from the backup power source, so that even in the event of a power outage, the door body 3 can be reliably locked after unlocking.

[0059] (3) In the fitting 1 described in (1) or (2) above, the backup power supply is arranged inside the fitting 1.

[0060] According to (3) above, a configuration that allows power to be supplied to the electric lock 5 from a backup power source can be easily formed simply by constructing the building fixture 1.

[0061] (4) In the fitting 1 described in any one of (1) to (3) above, the backup power source is a power storage device 102 that stores electricity supplied from a normal power source.

[0062] According to the above (4), the power storage device 102 can be kept in a fully charged state at all times, so there is no risk of a power shortage occurring when power is supplied from the standby power source.

[0063] (5) In the fitting 1 described in any one of (1) to (4) above, the second power supply path (the first wiring L1 and the second wiring L2) has a backup power supply power supply port 12.

[0064] According to (5) above, by using the backup power supply port 12, power can be supplied to the electric lock 5 from a portable external power source or the like via a second power supply path (first wiring L1 and second wiring L2), thereby improving convenience.

[0065] The present disclosure is not limited to the above-described embodiments, and includes modifications, improvements, etc. within the scope that can achieve the object of the present disclosure.

[0066] For example, at least one of the electric lock 5, authentication unit 6, control unit 8, backup power supply unit 10, and door detection unit 11 that constitute the electric lock system may be provided on the door body 3 side.

[0067] In the above embodiment, the fitting 1 has a door body 3 (door body) and a sleeve 4, and the latch portion is provided on the sleeve 4, but this is not limited to this. For example, the latch portion may be provided on the door body 3 (door body). Also, the fitting 1 may have only a frame 2 (door frame) and the door body 3 (door body), and may not have a sleeve 4. In this case, the latch portion may be provided on the door body 3 (door body) or on the frame 2 (door frame).

[0068] In the above embodiment, the latch unit that is not linked to the handle is configured by the roller latch 7, but is not limited to this. For example, the latch unit may be configured by a magnetic latch. A magnetic latch is a latch that uses magnetic force to hold the door body 3 closed when the door body 3 is closed, and when a force greater than the magnetic holding force is applied to the door body 3, the magnetic holding force is released, allowing the door body 3 to be opened.

[0069] In the above embodiment, the latch portion that is not linked to the handle is configured to be released by applying force to the door body 3 (door frame body) like the roller latch 7, but is not limited to this. The latch portion does not have to be linked to the handle. In this case, for example, the handle is not provided with a mechanism for releasing the latch portion, and a latch release button or the like is provided on the fixture separately from the handle. The latch portion is configured to be released when the latch release button is pressed.

[0070] The latch portion may be a normal latch portion that releases the closed state of the door body 3 when a user grips or rotates the handle of the door body 3 .

[0071] In the above embodiment, the sleeve portion 4 is provided and this sleeve portion 4 constitutes the facing portion, but this is not limited to this and the sleeve portion 4 may not be provided. For example, if the sleeve portion 4 is not provided, the facing portion may be formed by the vertical frame of the frame body or the wall of the building. In this case, the latch unit and the electric lock 5 may be provided on the vertical frame of the frame body or the wall of the building.

[0072] In the above embodiment, the sleeve portion 4 as the facing portion is configured as a sub-door that can be opened and closed, but the present invention is not limited to this. The sleeve portion 4 as the facing portion may be configured to be unable to be opened and closed.

[0073] In the above embodiment, the handle is configured as a handle having a vertical member extending in the vertical direction, but is not limited to this. For example, the handle may be formed in the shape of a door knob that protrudes from the surface of the door body (door body), or in the shape of a handle that is recessed from the surface of the door body (door body).
