Description

Building fixtures and entrances and exits, as well as building fixtures with authentication devices and methods for attaching authentication devices

[0001] The present disclosure relates to a building fixture including a door frame and a door body provided inside the door frame so as to be openable and closable. The present disclosure also relates to a building fixture to which an authentication device is attached.

[0002] Normally, an outdoor handle for manually opening and closing the door body from the outdoor side and an indoor handle for manually opening and closing the door body from the indoor side are attached to the building fixture.

[0003] Some building fixtures include a locking and unlocking mechanism, a cylinder, and a thumb turn. The locking and unlocking mechanism is configured to be able to be locked and unlocked when the door body is closed. The cylinder is configured to be manually operable from the outdoor side using a key to lock and unlock the locking and unlocking mechanism. The thumb turn is configured to be manually operable from the indoor side to lock and unlock the locking and unlocking mechanism.

[0004] Furthermore, some of such building fixtures include, in addition to these cylinders and thumb turns, an electric locking and unlocking device configured to be able to operate the locking and unlocking mechanism electrically.

[0005] In many building fixtures with authentication devices, the authentication device is attached to the outdoor wall surface.

[0006] Japanese Patent Application Laid-Open No. 2021-31978, Japanese Patent Application Laid-Open No. 2021-31978, Japanese Patent Application Laid-Open No. 2024-115366<s

[0007] The present inventors are promoting the development of building fixtures with excellent design quality. In particular, the aesthetics of the outdoor side of the building fixture is important. Therefore, it is preferable that the degree of design freedom of the outdoor side of the building fixture is high.

[0008] The present disclosure has been made in view of the above circumstances, and a first object thereof is to improve the degree of design freedom of the outdoor side of the building fixture.

[0009] In addition, the present inventors have focused on the following improvement points regarding a building fixture including such an electric locking and unlocking device. That is, in such a building fixture, since there is no need to manually operate the locking and unlocking mechanism, the cylinder and the thumb turn can be eliminated. Thereby, the degree of design freedom of the building fixture can be improved.

[0010] However, removing the cylinder exposes the part of the locking / unlocking mechanism that would normally connect to the cylinder, from inside the door / window frame to the outside. Therefore, if a specific part of the door / window frame on the outside is damaged, it becomes possible to access this part of the locking / unlocking mechanism from the outside using a tool or similar device. This makes the lock easier to pry open.

[0011] Furthermore, removing the thumbturn exposes the part of the locking / unlocking mechanism that is supposed to connect to the thumbturn, on the interior side of the door. As a result, if a designated part on the exterior side of the door is damaged, it becomes possible to access the part of the locking / unlocking mechanism that is supposed to connect to the thumbturn from the outside using a bent or broken tool. This makes the lock easier to pry open.

[0012] This disclosure is made in view of the above circumstances and has a second objective: to eliminate at least one of the cylinder and the thumbturn without making the lock easier to pry open.

[0013] Furthermore, in the case of building fixtures equipped with such authentication devices, the authentication device protrudes from the exterior wall surface. This detracts from the appearance of the exterior side of the fixture. For this reason, the present disclosers considered providing a recessed storage compartment on the exterior side of the fixture and housing the authentication device in that compartment.

[0014] However, even in this case, the disclosers noted the following area for improvement: the exposure of parts of the authentication device that do not require visual inspection still results in an unsightly exterior appearance of the building fixture.

[0015] In the above explanation, we described the case where the authentication device is installed on the exterior side of the door or window, but similar problems arise when the authentication device is installed on the interior side of the door or window.

[0016] This disclosure is made in view of the above circumstances, and its third purpose is to improve the appearance of building components equipped with authentication devices.

[0017] To achieve the first objective, the joinery of this disclosure comprises a door frame and a door body installed inside the door frame so as to be openable and closable, wherein the door body is equipped with an electric opening and closing device configured to be openable and closable electrically, and at least on the exterior side of the door body there is no door handle for manually opening the door body.

[0018] To achieve the second objective, the joinery of this disclosure comprises a door frame, a door body provided inside the door frame so as to be openable and closable, and a locking / unlocking mechanism configured to be lockable and unlockable when the door body is closed, wherein the joinery comprises an electric locking / unlocking device configured to be electrically operable for the locking / unlocking mechanism, and a shielding plate provided at a position that overlaps in front of the locking / unlocking mechanism when viewed from a predetermined side, either the exterior or interior side, when the joinery is locked.

[0019] To achieve a third objective, the authentication device attached to the building component of the present disclosure is an authentication device attached to a building component, wherein the building component is provided with a storage compartment having a window, the authentication device is longer in a predetermined direction than the window, the authentication device comprises a first part and a second part arranged in the predetermined direction, and the authentication device is housed in the storage compartment such that, in a front view of the building component from the front of the window, the first part of the authentication device is visible and the second part of the authentication device is not visible.

[0020] The authentication device mounting method of this disclosure is an authentication device mounting method for mounting an authentication device to a building fixture, comprising a preparation step of preparing a building fixture having a storage compartment with a window, and an authentication device unit including the authentication device, wherein the authentication device is longer than the window in a predetermined direction, the authentication device comprises a first authentication device part and a second authentication device part arranged in the predetermined direction, the authentication device has a back plate attached to it that protrudes from the authentication device, and the authentication device mounting method further comprises a storage step of storing the authentication device unit in the storage compartment by passing it through the window from the front of the window, and a fixing step of fixing the tip of the back plate to the building fixture, wherein the authentication device is stored in the storage compartment such that, in a front view of the building fixture from the front of the window, the first authentication device part is visible and the second authentication device part is not visible.

[0022] The embodiments of this disclosure will be described below with reference to the drawings. However, this disclosure is not limited in any way to the embodiments described below, and may be implemented with appropriate modifications without departing from the spirit of this disclosure.

[0023] [First Embodiment] As shown in Figure 1, the joinery 100 comprises a door frame 10, a side panel 20, and a door body 60.

[0024] In the following, as shown in Figure 6, the thickness direction of the door body 60 is referred to as the "door thickness direction Y". The side facing from the outside to the inside in the door thickness direction Y is referred to as the "indoor side Y-", and the side facing from the inside to the outside in the door thickness direction Y is referred to as the "outdoor side Y+". In the following, the width direction of the door body 60 is referred to as the "door width direction X". The side facing from the leading edge to the trailing edge of the door body 60 in the door width direction X is referred to as the "trailing edge side X-", and the side facing from the trailing edge to the leading edge of the door body 60 in the door width direction X is referred to as the "leading edge side X+".

[0025] As shown in Figure 2, the joinery 100 is configured to be lockable and unlockable when the door body 60 is closed. Hereinafter, the state in which the joinery 100 is locked will be referred to as the "locked state". Unless otherwise specified, the positional relationships in the following description are those as viewed in the locked state.

[0026] The tail end X- of the door body 60 is rotatably attached to the door frame 10 via hinges or the like. Therefore, the door body 60 is installed inside the door frame 10 so as to be able to open and close. The side portion 20 is installed inside the door frame 10, on the tail end X+ side of the door body 60.

[0027] As shown in Figure 6, the door body 60 includes an exterior surface material 63 and an interior surface material 67 arranged side by side in the door thickness direction Y. The door body 60 also includes a tail-side vertical frame 65a, an upper frame 65b, a leading-side vertical frame 65c, and a lower frame 65d, as shown in Figure 2. The tail-side vertical frame 65a extends vertically at the tail-side X- end of the door body 60. The upper frame 65b extends in the door width direction X at the upper end of the door body 60. The leading-side vertical frame 65c extends vertically at the leading-side X+ end of the door body 60. The lower frame 65d extends in the door width direction X at the lower end of the door body 60.

[0028] As shown in Figure 6, a strike plate 662 and a tumbler 667 are provided at the leading edge X+ end of the door body 60.

[0029] As shown in Figure 3, the door 100 includes a box lock 30 and an electric locking / unlocking device 40 within the side section 20. The box lock 30 includes a locking / unlocking mechanism 35 and a box body 31 that houses the locking / unlocking mechanism 35. The locking / unlocking mechanism 35 is configured to lock and unlock the door 100 when the door body 60 is closed.

[0030] Specifically, the locking / unlocking mechanism 35 includes a rotatable rotating part 354 and a locking / unlocking part 356 that switches between locking and unlocking in conjunction with the rotation of the rotating part 354. An outdoor opening 313 is provided on the outdoor Y+ surface of the box body 31 to allow a cylinder to be connected to the rotating part 354 of the locking / unlocking mechanism 35. An indoor opening 317 is provided on the indoor Y- surface of the box body 31 to allow a thumbturn 47 to be connected to the rotating part 354 of the locking / unlocking mechanism 35.

[0031] The electric locking / unlocking device 40 is configured to allow the locking / unlocking mechanism 35 to be operated electrically. In this embodiment, the electric locking / unlocking device 40 is located inside the thumbturn 47, which will be described later. That is, the electric locking / unlocking device 40 is part of the thumbturn 47, and the thumbturn 47 is an electric thumbturn. However, instead, the electric locking / unlocking device 40 may be located, for example, inside the box body 31. That is, the electric locking / unlocking device 40 is part of the box lock 30, and the box lock 30 may be an electric box lock.

[0032] As shown in Figure 2, the joinery 100 is equipped with an electric opening and closing device 90. This electric opening and closing device 90 is configured to allow the door body 60 to be opened and closed electrically. Specifically, the electric opening and closing device 90 of this embodiment is configured such that an electric opener for electrically opening the door body 60 and an electric closer for electrically closing the door body 60 are integrally provided. However, instead, the electric opening and closing device 90 may also include an electric opener and an electric closer provided separately.

[0033] With the above configuration, the door / window 100 is configured to be automatically lockable and unlockable, and automatically openable and closable.

[0034] Specifically, as shown in Figure 1, for example, an authentication device 25 is installed on the exterior side Y+ of the door 100. When the authentication device 25 authenticates that the person on the exterior side Y+ of the door 100 is a registered resident or other person, the electric locking / unlocking device 40 automatically unlocks the door 100, and then the electric opening / closing device 90 automatically opens the door body 60. This allows the person on the exterior side Y+ of the door 100 to enter. After that, the electric opening / closing device 90 automatically closes the door body 60, and then the electric locking / unlocking device 40 automatically locks the door 100.

[0035] For example, on the interior side Y- of the door 100 shown in Figure 2, there is a switch (not shown). When this switch is pressed by a person inside the room, the electric locking / unlocking device 40 automatically unlocks the door 100, and then the electric opening / closing device 90 automatically opens the door body 60. This allows the person inside the room to exit. After that, the electric opening / closing device 90 automatically closes the door body 60, and then the electric locking / unlocking device 40 automatically locks the door 100.

[0036] However, instead of the above, for example, the electric locking / unlocking device 40 may be configured to lock and unlock the door 100 and the electric opening / closing device 90 may be configured to open and close the door body 60 based on the operation of a remote control or the like.

[0037] Based on the above, the joinery 100 shown in Figure 1 basically does not require a cylinder, thumbturn, exterior handle, or interior handle.

[0038] However, in the event of an emergency such as a power outage, a thumbturn 47 and an indoor handle 87 are provided on the indoor side Y- of the door 100, as shown in Figure 2, so that the door can be manually unlocked and opened from the indoor side Y-. On the other hand, as shown in Figure 1, neither a cylinder nor an outdoor handle is provided on the outdoor side Y+ of the door 100, from the viewpoint of design and other considerations.

[0039] In this embodiment and the following embodiments, "cylinder" refers to a mechanism for manually operating the locking / unlocking mechanism 35 from the outside Y+ using a key. "Thumbturn" refers to a mechanism for manually operating the locking / unlocking mechanism 35 from the inside Y-. "Outside handle" refers to a handle for manually opening and closing the door body 60 from the outside Y+. "Inside handle" refers to a handle for manually opening and closing the door body 60 from the inside Y-. Note that "outside handle" and "inside handle" may be read as "door handle".

[0040] Next, the first problem to be solved in this embodiment will be explained. As mentioned above, in this embodiment, as shown in Figure 3, there is no cylinder. As a result, if it remains as is, that is, without the shielding plate 38 shown in Figure 3 which will be described later, the part of the rotating part 354 of the locking / unlocking mechanism 35 that is supposed to connect to the cylinder will be exposed to the outside Y+ by the outside opening 313 of the box body 31. As a result, if the part of the sleeve 20 that is located outside Y+ of the box lock 30 is destroyed, it will be possible to access the part of the rotating part 354 of the locking / unlocking mechanism 35 that is supposed to connect to the cylinder from the outside Y+ of the sleeve 20 using a jig or the like. As a result, the lock will be easily pried open.

[0041] To solve this problem, the joinery 100 of this embodiment is equipped with a shielding plate 38 as shown in Figure 3. As shown in Figure 5, this shielding plate 38 is attached to the exterior Y+ surface of the box body 31 so as to cover the exterior opening 313. As a result, as shown in Figure 5, the shielding plate 38 overlaps the locking / unlocking mechanism 35 when viewed from the exterior Y+ side. This shielding plate 38 makes it difficult to pry open the lock.

[0042] Next, a second problem to be solved in this embodiment will be described. As described above, as shown in Figure 3, a cylinder is not provided in this embodiment. Therefore, the thumbturn 47 cannot be fixed to the cylinder 43 while connected to the locking / unlocking mechanism 35. Therefore, as it is, the thumbturn 47 cannot be fixed to the box lock 30.

[0043] To solve this problem, in the present embodiment, the thumb turn 47 is fixed to the shielding plate 38 instead of the cylinder while being connected to the locking and unlocking mechanism 35. Therefore, even when there is no cylinder as in the present embodiment, the thumb turn 47 can be fixed to the mortise lock 30 without any problem.

[0044] Next, a third problem to be solved in the present embodiment will be described. As described above, as shown in FIG. 1, an outdoor handle is not attached to the door body 60 of the present embodiment. Therefore, the indoor handle 87 shown in FIG. 2 cannot be fixed to the outdoor handle. Therefore, as it is, the indoor handle 87 cannot be fixed to the door body 60.

[0045] To solve this problem, as shown in FIG. 2, the fitting 100 of the present embodiment includes a back plate 70 inside the door body 60. The indoor handle 87 is fixed to the back plate 70. Therefore, even when there is no outdoor handle as in the present embodiment, the indoor handle 87 can be fixed to the door body 60 without any problem.

[0046] Next, the shielding plate 38 shown in FIG. 5 will be described in more detail. This shielding plate 38 is made of metal.

[0047] On the outdoor side Y+ surface of the box body 31, a plurality of protrusions 318 protruding in the outdoor side Y+ direction are provided. The shielding plate 38 is provided with holes 381 for each of these protrusions 318. By the engagement of the plurality of protrusions 318 and the holes 381, the shielding plate 38 is positioned in the vertical direction and the door width direction X.

[0048] As shown in Fig. 4, a long hole f1a extending in the vertical direction is provided on the室内側Y− surface of the box body 31. As shown in Fig. 5, a long hole f1b extending in the vertical direction is also provided on the室外側Y+ surface of the box body 31. The shielding plate 38 is provided with a hole f1c. The shielding plate 38 is fastened to the box body 31 by a fastening member F1 passing through these long holes f1a, f1b and the hole f1c. More specifically, for example, the fastening member F1 is a male screw, and the hole f1c of the shielding plate is a female screw. The fastening member F1 passes through the long holes f1a, f1b of the box body 31 and is screwed into the hole f1c of the shielding plate 38. However, alternatively, the fastening member F1 may be a screw, and the hole f1c of the shielding plate 38 may be a mere hole other than a female screw. Thus, the shielding plate 38 is fixed to the box body 31.

[0049] As shown in Fig. 5, when viewed from the室外側Y+ side, a plurality of holes f2 are provided in the portion of the shielding plate 38 that overlaps in front of the outdoor side opening 313. As shown in Fig. 3, a fastening member F2 originally for fixing the thumb turn 47 to the cylinder and a fastening member slightly shorter than that are fastened to these holes f2. More specifically, for example, the fastening member F2 is a male screw, and the hole f2 of the shielding plate 38 is a female screw. However, alternatively, the fastening member F2 may be a screw, and the hole f2 of the shielding plate 38 may be a mere hole other than a female screw. Thus, the thumb turn 47 is fixed to the shielding plate 38 in a state of being connected to the locking and unlocking mechanism 35.

[0050] Next, the back plate 70 shown in Fig. 2 will be described in more detail. As shown in Fig. 2, when viewed from the室内側Y− side, the back plate 70 is provided one by one in the portion behind the upper part and the portion behind the lower part of the indoor handle 87.

[0051] As shown in Figure 6, each backing plate 70 is provided on the inside of the door body 60, that is, between the exterior surface material 63 and the interior surface material 67. The backing plate 70 comprises an interior metal portion 77, a connecting portion 75, and an exterior metal portion 73. As shown in Figure 6, the interior metal portion 77 extends along the interior surface material 67. The exterior metal portion 73 extends along the exterior surface material 63. The connecting portion 75 connects the end of the exterior metal portion 73 on the door edge side X+ to the end of the interior metal portion 77 on the door edge side X+. Therefore, the backing plate 70 has an opening on the door tail side X-.

[0052] As shown in Figure 7, the backing plate 70 further comprises an indoor-side Y- resin material 78 and an outdoor-side Y+ resin material 72. In this embodiment, there are two indoor-side Y- resin materials 78 and one outdoor-side Y+ resin material 72, but there may be only one or three or more indoor-side Y- resin materials 78, or two or more outdoor-side Y+ resin materials 72. Each of these resin materials 78, 72 extends in the vertical direction and the door width direction X.

[0053] The resin material 78 on the indoor side Y- is attached to the indoor side Y- surface of the indoor side portion 77. Specifically, as shown in Figure 8, the indoor side portion 77 is provided with a plurality of elongated holes f3 extending in the door width direction X. As shown in Figure 9, the resin materials 78 are attached to the indoor side portion 77 by engaging projections F3 provided on each resin material 78 on the indoor side Y- with their respective elongated holes f3. Similarly, the resin material 72 on the outdoor side Y+ is attached to the outdoor side Y+ surface of the outdoor side portion 73. Specifically, as shown in Figure 10, the outdoor side portion 73 is also provided with a plurality of elongated holes f6 extending in the door width direction X. As shown in Figure 6, the resin material 72 is attached to the outdoor side portion 73 by engaging projections F6 provided on each resin material 72 on the outdoor side Y+ with their respective elongated holes f6. As shown in Figures 7 and 9, notches 785 and 725 are provided in the vertical center of each resin material 78 and 72. The hole f7a in the indoor side 77 shown in Figure 7, which will be described later, is exposed by this notch 785.

[0054] As shown in Figure 7, a hole f5 is provided in the connecting portion 75. As shown in Figure 6, the connecting portion 75 is fixed to the door-side core material 68, which extends vertically along the door-side vertical frame 65c, by a fastening material F5 that passes through the hole f5. The fastening material F5 is a screw or bolt, etc.

[0055] As shown in Figure 7, the backing plate 70 described above is divided into an indoor backing plate 70i and an outdoor backing plate 70o. The indoor backing plate 70i includes an indoor Y- resin material 78, an indoor portion 77, and an indoor portion 75i of the connecting portion 75 as part of the connecting portion 75. On the other hand, the outdoor backing plate 70o includes an outdoor portion 75o of the connecting portion 75 as the part of the connecting portion 75 other than the indoor portion 75i, an outdoor portion 73, and an outdoor Y+ resin material 72. The outdoor Y+ portion of the indoor portion 75i of the connecting portion and the indoor Y- portion of the outdoor portion 75o of the connecting portion are overlapped in the door width direction X.

[0056] As shown in Figure 6, one of the connecting section's interior side portion 75i and the connecting section's exterior side portion 75o is provided with an elongated hole f4b extending in the door width direction X. The other of the connecting section's interior side portion 75i and the connecting section's exterior side portion 75o is provided with a hole f4a communicating with the elongated hole f4b. The connecting section's interior side portion 75i and the connecting section's exterior side portion 75o are connected to each other by fasteners F4 passing through the elongated hole f4b and the hole f4a. Note that there are two of each of these elongated holes f4b, holes f4a, and fasteners F4, spaced apart in the vertical direction, as shown in the fasteners F4 in Figure 7. In this way, the interior side back plate 70i and the exterior side back plate 70o are connected to each other. Each fastener F4 is a screw or bolt. The dimension of the back plate 70 in the door thickness direction Y can be adjusted within the range of the elongated hole f4 shown in Figure 6.

[0057] As shown in Figure 7, the connecting portion 75 is provided with a bypass portion 756. The bypass portion 756 extends toward the door tail side X-, extends toward the exterior side Y+ from its tip, and extends toward the door edge side X+ from its tip. As shown in Figure 6, a trapdoor 667 is provided inside the bypass portion 756.

[0058] As shown in Figure 8, an inclined portion 74 is provided between the outdoor portion 73 and the connecting portion 75, extending in a direction oblique to both the door width direction X and the door thickness direction Y. A protruding portion 754 is provided in the portion of the connecting portion 75 that is located on the outdoor side Y+ from the hole f5, projecting outwards Y+. As shown in Figure 10, the inclined portion 74 is provided with an opening 744 for forming the protruding portion 754.

[0059] As shown in Figure 11, the upper and lower parts of the indoor handle 87 are provided with bases 86 that protrude outwards Y+. As shown in Figure 6, these bases 86 are fixed to the indoor side portion 77 of the backing plate 70 by fasteners F7 such as screws or bolts. Specifically, for example, a boss 85 is attached to the base 86 by fasteners F8 and F9 such as screws or bolts. The boss 85 has a hole f7c. The surface material 67 has a hole f7b that communicates with the hole f7c of the boss 85. The hole f7b of the surface material 67 communicates with a hole f7a of the indoor side portion 77 of the backing plate 70 through a notch 785 in the resin material 78. The bases 86 are fixed to the indoor side portion 77 of the backing plate 70 by the aforementioned fasteners F7 that pass through these holes f7a, f7b, and f7c. In this way, the indoor handle 87 is fixed to the backing plate 70.

[0060] The configuration and effects of this embodiment are summarized below.

[0061] As shown in Figure 3, the door 100 is equipped with an electric locking / unlocking device 40. This eliminates the need for a cylinder. This improves the design freedom of the exterior side Y+ of the door 100. For example, the exterior side Y+ of the door 100 shown in Figure 1 can be made into a clean design with fewer protruding structures.

[0062] However, simply removing the cylinder would make the lock easier to pry open, as mentioned in the first problem above. In this embodiment, as shown in Figure 5, a shielding plate 38 is provided in a position that overlaps with the locking / unlocking mechanism 35 when viewed from the outside Y+. This shielding plate 38 makes it difficult to pry open the lock. Moreover, as shown in Figure 1, the absence of the cylinder, which is the original target for prying, also makes it difficult to pry open the lock.

[0063] As described above, according to this embodiment, by eliminating the cylinder and providing the shielding plate 38, the degree of design freedom of the exterior side Y+ of the door 100 can be improved without making the lock easier to pry open.

[0064] The locking / unlocking mechanism 35 shown in Figure 3 is housed inside the box body 31. As shown in Figure 5, the box body 31 is provided with an outdoor opening 313 that exposes the locking / unlocking mechanism 35 to the outdoor side Y+. This outdoor opening 313 is originally intended to allow the cylinder to be connected to the locking / unlocking mechanism 35, and is unnecessary in this embodiment. The shielding plate 38 is attached to the box body 31 so as to cover this outdoor opening 313. Therefore, a standard box lock 30, that is, a box lock 30 with a cylinder that can be connected, can be used as is or without significant structural modifications.

[0065] As shown in Figure 3, the thumbturn 47 is fixed to the shielding plate 38, not to the cylinder, while connected to the locking / unlocking mechanism 35. Therefore, even in the absence of a cylinder as in this embodiment, the thumbturn 47 can be attached to the locking / unlocking mechanism 35 without any problems.

[0066] As shown in Figure 1, a side panel 20 is provided on the side of the door body 60. A box lock 30 and a shielding plate 38 are provided within the side panel 20. Therefore, the thumbturn 47 shown in Figure 2 can be placed on the side panel 20 instead of the door body 60. This improves the aesthetic design of the interior side Y- of the joinery 100.

[0067] As shown in Figure 2, the door 100 is equipped with an electric opening and closing device 90. Therefore, as shown in Figure 1, the exterior handle can be eliminated. This improves the design freedom of the exterior Y+ of the door 100. For example, the exterior Y+ of the door 100 can be designed to be clean and uncluttered with fewer protruding structures.

[0068] While the door 100 does not have an exterior handle, as shown in Figure 2, it does have an interior handle 87. Therefore, even in emergencies such as power outages, the door 100 can be opened manually from the interior Y-. In addition, the door body 60 can be closed manually from the interior Y- in case of strong winds or for security purposes.

[0069] As shown in Figure 2, a backing plate 70 is provided inside the door body 60. The interior handle 87 is attached to the door body 60 by being fixed to this backing plate 70, rather than to the exterior handle. Therefore, even in the case of not having an exterior handle as in this embodiment, the interior handle 87 can be attached to the door body 60 without any problems.

[0070] As shown in Figure 6, the indoor portion 77 of the backing plate 70 extends along the indoor surface material 67. The outdoor portion 73 extends along the outdoor surface material 63. The connecting portion 75 connects the door-edge side X+ end of the indoor portion 77 to the door-edge side X+ end of the outdoor portion 73. As a result, the backing plate 70 opens toward the door-end side X-. By shaping the backing plate 70 to conform to the inside of the door body 60 in this way, the backing plate 70 is less likely to curl up when the door body 60 is opened and closed manually using the indoor handle 87.

[0071] Furthermore, the connecting portion 75 is fixed to the door-side core material 68. This makes it even more difficult for the backing plate 70 to curl up.

[0072] As shown in Figure 7, the backing plate 70 is divided into an indoor backing plate 70i and an outdoor backing plate 70o. The indoor backing plate 70i includes an indoor portion 77 and an indoor portion 75i of the connecting portion 75. The outdoor backing plate 70o includes an outdoor portion 75o of the connecting portion 75, which is the part of the connecting portion 75 other than the indoor portion 75i, and an outdoor portion 73. The indoor portion 75i and the outdoor portion 75o of the connecting portion are connected to each other. By dividing the backing plate 70 in this way, the backing plate 70 can be manufactured more easily than when the entire backing plate 70 is formed as a single piece.

[0073] As shown in Figure 7, the interior side portion 75i and the exterior side portion 75o of the connecting section are overlapped in the door width direction X. As shown in Figure 6, one of the interior side portion 75i and the exterior side portion 75o of the connecting section is provided with an elongated hole f4b extending in the door thickness direction Y. The other of the interior side portion 75i and the exterior side portion 75o of the connecting section is provided with a hole f4a. The interior side portion 75i and the exterior side portion 75o of the connecting section are connected to each other by fasteners F4 that pass through the elongated hole f4b and hole f4a. As a result, the dimension of the backing plate 70 in the door thickness direction Y can be easily adjusted within the range of the elongated hole f4b.

[0074] As shown in Figure 7, the avoidance portion 756 of the connecting portion 75 extends toward the door tail side X-, extends from its tip toward the door thickness direction Y, and extends from its tip toward the door edge side X+. As shown in Figure 6, a trowel stopper 667 is provided inside the avoidance portion 756. This prevents interference between the connecting portion 75 and the trowel stopper 667. As a result, the backing plate 70 can be positioned at the same height as the trowel stopper 667. This improves the flexibility of the dimensions and position of the interior handle 87.

[0075] [Second Embodiment] Next, a second embodiment will be described with reference to Figure 12. The following embodiments will be described based on the first embodiment, focusing on the differences, and explanations of the same or similar aspects as the first embodiment will be omitted as appropriate.

[0076] As shown in Figure 12, the box body 31 in this embodiment does not have the "outdoor opening 313" as described in the first embodiment shown in Figure 3. Therefore, the box body 31 in this embodiment shown in Figure 12 houses the locking / unlocking mechanism 35 so as not to be exposed to the outdoor side Y+.

[0077] In other words, in this embodiment, the shielding plate 38 is integrally formed with the box body 31. That is, in this embodiment, the shielding plate 38 is the part of the box body 31 that is on the outdoor side Y+ from the locking / unlocking mechanism 35.

[0078] According to this embodiment, the number of parts in the joinery 100 can be reduced by integrally forming the shielding plate 38 with the box body 31.

[0079] [Third Embodiment] Next, a third embodiment will be described with reference to Figures 13 to 15. As shown in Figure 14, the door 100 of this embodiment does not have a thumbturn and an interior handle, but instead has a cylinder 43 and an exterior handle 83, as shown in Figure 13.

[0080] In this embodiment, as shown in Figure 15, an electric locking / unlocking device 40 is provided inside the box 31. That is, the electric locking / unlocking device 40 is part of the box lock 30, and the box lock 30 is an electric box lock.

[0081] As shown in Figure 15, the shielding plate 38 is attached to the box body 31 so as to cover the indoor opening 317. Therefore, when viewed from the indoor side Y- in the locked state, the shielding plate 38 overlaps the front of the locking / unlocking mechanism 35. The cylinder 43 is fixed to the shielding plate 38 while connected to the locking / unlocking mechanism 35. This fixing structure is substantially the same as that of the thumbturn 47 in the first embodiment.

[0082] The outdoor handle 83 shown in Figure 13 is fixed to the back plate 70 in substantially the same way as the indoor handle 87 in the first embodiment.

[0083] According to this embodiment, as shown in Figure 15, the door 100 is equipped with an electric locking / unlocking device 40. This eliminates the need for a thumbturn. As a result, the design freedom of the interior side Y- of the door 100 shown in Figure 14 can be improved. This allows for a cleaner design of the interior side Y- of the door 100, for example, with fewer protruding structures.

[0084] However, simply removing the thumbturn would lead to the following problem. Specifically, if the part of the sleeve portion 20 shown in Figure 15 that is located on the outside Y+ side, rather than around the box lock 30, is destroyed, it becomes possible to access the part of the locking / unlocking mechanism 35 that is originally intended to connect to the thumbturn from the outside Y+ side using a bent jig or the like. As a result, the lock becomes easier to pry open. In this embodiment, however, a shielding plate 38 is provided at a position that overlaps with the locking / unlocking mechanism 35 when viewed from the inside Y- side. This shielding plate 38 makes it difficult to pry open the lock.

[0085] As described above, according to this embodiment, as shown in Figure 14, by eliminating the thumbturn and providing the shielding plate 38, it is possible to improve the design freedom of the interior side Y- of the door 100 without making the lock easier to pry open.

[0086] The locking / unlocking mechanism 35 shown in Figure 15 is housed inside the box body 31. The box body 31 is provided with an interior opening 317 that exposes the locking / unlocking mechanism 35 to the interior side Y-. This interior opening 317 is originally intended to allow a thumbturn to be connected to the locking / unlocking mechanism 35, and is unnecessary in this embodiment. The shielding plate 38 is attached to the box body 31 so as to cover this interior opening 317. Therefore, a standard box lock 30, that is, a box lock 30 with a specification that allows a thumbturn to be connected, can be used as is or without significant structural modifications.

[0087] As shown in Figure 15, the cylinder 43 is fixed to the shielding plate 38, not to the thumbturn, while connected to the locking / unlocking mechanism 35. Therefore, even in the absence of a thumbturn as in this embodiment, the cylinder 43 can be attached to the locking / unlocking mechanism 35 without any problems.

[0088] [Fourth Embodiment] Next, the fourth embodiment will be described with reference to Figure 16. In this embodiment, not only is there no cylinder and outdoor handle on the outdoor side Y+, but there is also no thumbturn and indoor handle on the indoor side Y-. Therefore, the shielding plate 38 consists of an outdoor shielding plate 38 and an indoor shielding plate 38. The outdoor shielding plate 38 closes the outdoor opening 313, similar to that of the first embodiment. The indoor shielding plate 38 closes the indoor opening 317, similar to that of the second embodiment. The outdoor shielding plate 38 overlaps in front of the locking / unlocking mechanism 35 when viewed from the outdoor side Y+. The indoor shielding plate 38 overlaps in front of the locking / unlocking mechanism 35 when viewed from the indoor side Y-. In this embodiment as well, similar to that of the third embodiment, an electric locking / unlocking device 40 is provided inside the box body 31. That is, the box lock 30 is an electric box lock.

[0089] According to this embodiment, the degree of design freedom can be improved on both the outdoor side Y+ and the indoor side Y-.

[0090] [Fifth Embodiment] Next, a fifth embodiment will be described with reference to Figure 17. The entrance 300 of this embodiment includes the door 100 of the first embodiment and a second door 200 separate from the door 100. The second door 200 is provided in the vicinity of the door 100 and, for example, leads to the same entrance. In this embodiment, as shown in Figure 17, the door 100 and the second door 200 are provided side by side on the door width X side, but other arrangements are also possible.

[0091] The second door / window 200 is a standard door / window that is manually locked, unlocked, and opened and closed. Therefore, the second door / window 200 is equipped with a cylinder 243 and an exterior handle 283 on the exterior side Y+, and a thumbturn 247 and an interior handle 287 on the interior side Y-.

[0092] According to this embodiment, even during a power outage, it is possible to enter and exit the room through the second door 200 without any problems. Furthermore, it is also possible to use the door 100 only at predetermined times, such as when guests are visiting, and use the second door 200 at all other times.

[0093] [Modified Embodiments of the First to Fifth Embodiments] The above embodiments can be implemented with modifications as follows, for example. In each embodiment, the door body 60 shown in Figure 1, etc., may be a sliding door instead of a swing door. In each embodiment, the box lock 30 and the shielding plate 38 may be provided inside the door body 60 or the door frame 10 instead of inside the side portion 20.

[0094] [Sixth Embodiment] As shown in Figure 18, the authentication device-equipped door α180 includes a door α150 and an authentication device unit α100. The door α150 is installed between the exterior and interior of a room. The authentication device unit α100 is attached to the door α150.

[0095] Hereafter, the exterior side will be referred to as "front Fr," and the interior side as "rear Rr." Also, the left side as viewed from front Fr will be referred to as "left Lh," and the right side as viewed from front Fr will be referred to as "right Rh." In the following, "front Fr" may be read as "front," "rear" as "back," and "up and down direction" as "specified direction."

[0096] As shown in Figure 18, the joinery α150 comprises a door frame α110, a side section α120, and a door body α130. The door body α130 is installed inside the door frame α110 so as to be openable and closable. The side section α120 is installed inside the door frame α110 to the left Lh of the door body α130. The side section α120 is provided with a storage section α127 in which a window α128 is installed. Hereinafter, the view of the joinery α150 from in front of the window α128 Fr will be referred to as the "front view".

[0097] As shown in Figure 20, the authentication device unit α100 includes an authentication device α50, a back plate α60, and a case α70.

[0098] As shown in Figure 23, the authentication device α50 comprises an authentication device body α30 and a back plate α40 that abuts against its rear surface. The back plate α60 abuts against the back plate α40 and protrudes to the right Rh from the authentication device α50. As shown in Figure 19, the authentication device α50 is housed inside the case α70.

[0099] As shown in Figure 1, the authentication device body α30 is longer vertically than the window α128. The authentication device body α30 comprises an authentication device first part α31 and an authentication device second part α38 arranged vertically. Specifically, the majority of the authentication device body α30 is the authentication device first part α31, and the authentication device second part α38 is located below the authentication device first part α31. Therefore, the authentication device unit α100 is housed in the storage section α127 in such a way that the authentication device first part α31 is visible from the front, but the authentication device second part α38 is not.

[0100] As shown in Figure 19, the case α70 comprises a first case part α71 that houses the first authentication device part α31, and a second case part α78 that houses the second authentication device part α38. The first case part α71 is provided with a case window α711 that allows the first authentication device part α31 to be seen within the window α128. A flange α71p is provided in a ring shape in a front view on the portion of the first case part α71 that is located around the case window α711, projecting toward the opposite side of the case window α711.

[0101] As shown in Figure 26, the backing plate α60 is mounted lower to the authentication device α50, that is, the vertical center of the backing plate α60 is closer to the second authentication device part α38 than the vertical center of the authentication device α50. More specifically, the backing plate α60 is mounted to the second authentication device part α38 such that at least a part of it is directly behind the second authentication device part α38. As a result, as shown in Figure 27, the authentication device unit α100 is configured to be able to be stored in the storage part α127 by passing it through the front of the window α128 Fr from the window α128 during installation work on the joinery α150. As shown in Figure 28, the right end of the backing plate α60 is fixed to the sleeve part α120.

[0102] Next, a method for attaching the authentication device unit α100 to the joinery α150 shown in Figure 18 will be described. The authentication device attachment method of this embodiment includes a preparation step shown in Figure 25, a storage step shown in Figures 26 and 27, and a fixing step shown in Figure 28. In the preparation step S1, as shown in Figure 25, the joinery α150 and the authentication device unit α100 are prepared in the stage before the authentication device unit α100 is attached to the joinery α150. In the subsequent storage step S2, the authentication device unit α100 shown in Figure 26 is passed from the front Fr of the window α128 through the window α128 as shown in Figure 27 and stored in the storage section α127. In the subsequent fixing step S3, as shown in Figure 28, the right end of the back plate α60 is fixed to the sleeve section α120. By doing so, the joinery α180 with the authentication device shown in Figure 1 is constructed.

[0103] Next, this embodiment will be described in more detail.

[0104] The right end of the door body α130 shown in Figure 18 is rotatably attached to the door frame α110 via hinges or the like. An exterior handle α95 is attached to the left end of the front surface of the door body α130. An interior handle (not shown) is attached to the rear surface of the door body α130, at the part Rr behind the exterior handle α95.

[0105] As shown in Figure 28, the sleeve portion α120 comprises two front and rear surface plates α121 and α126, and two left and right vertical core members α122 and α124. The front surface plate α121 extends along the front surface of the sleeve portion α120. The rear surface plate α126 extends along the rear surface of the sleeve portion α120. The left vertical core member α122 extends along the left side surface of the sleeve portion α120. The right vertical core member α124 extends along the right side surface of the sleeve portion α120. The sleeve portion α120 may be a sub-door that can be opened and closed, or a fixed sleeve portion that cannot be opened and closed.

[0106] In this embodiment, the authentication device α50 shown in Figure 18 is a facial recognition device. However, it may be another authentication device such as a fingerprint recognition device. In this embodiment, when the authentication device α50 authenticates that the person standing in front of the door α150 Fr is a registered person such as a resident, the door α150 is automatically unlocked.

[0107] As shown in Figure 20, the first authentication device part α31 protrudes forward Fr than the second authentication device part α38. For example, a camera α34 and a display α33 are provided on the front surface of the first authentication device part α31.

[0108] The back plates α40 and α60 shown in Figure 23 are both metal plates. On the other hand, the case α70 is made of resin. Specifically, in this embodiment, the case α70 includes PC (polycarbonate) and ABS resin.

[0109] As shown in Figure 21, wiring W1 is connected to the authentication device body α30. A projection α45 is provided at the lower end of the back plate α40, which protrudes forward Fr. A hole α46 is provided in the projection α45 for passing the wiring W1 through.

[0110] As shown in Figure 20, the first case part α71 comprises a left side part α712, an upper part α713, a right side part α714, a lower part α715, and a rear part α716. The left side part α712 extends along the left side of the first authentication device part α31. The upper part α713 extends along the upper surface of the first authentication device part α31. The right side part α714 extends along the right side of the first authentication device part α31. The lower part α715 extends along the lower surface of the first authentication device part α31. The lower surface of the first authentication device part α31 refers to the lower surface of the portion that protrudes forward Fr from the upper end of the second authentication device part α38. The rear part α716 extends along the upper rear surface of the first authentication device part α31. The portion enclosed by the front end of the left side portion α712, the front end of the upper portion α713, the front end of the right side portion α714, and the front end of the lower portion α715 constitutes the aforementioned case window α711. Outside of this, the aforementioned annular flange α71p, as seen in the front view, is provided.

[0111] As shown in Figure 23, the second case part α78 comprises a left side part α782, a front part α781, and a right side part α784. The left side part α782 extends along the left side of the second authentication device part α38. The front part α781 extends along the front of the second authentication device part α38. The right side part α784 extends along the right side of the second authentication device part α38.

[0112] As shown in Figure 22, the back plate α60 comprises a first back plate part α61, a second back plate part α62, a third back plate part α63, and two upper and lower fourth back plate parts α64. The first back plate part α61 is attached to the lower rear surface of the authentication device α50. More specifically, as shown in Figure 22, the first back plate part α61 is attached to the lower rear surface of the first authentication device part α31 and the rear surface of the second authentication device part α38 via the back plate α40. As shown in Figure 22, this first back plate part α61 extends along the rear surface of the authentication device α50. The second back plate part α62 extends rearward Rr from the right end of the first back plate part α61. The third back plate part α63 extends rightward Rh from the rear end of the second back plate part α62. The upper back plate fourth section α64 extends posteriorly Rr from the upper right end of the back plate third section α63. The lower back plate fourth section α64 extends posteriorly Rr from the lower right end of the back plate third section α63.

[0113] As shown in Figure 24, two engaging recesses αf1 are provided at the upper end of the rear surface of the authentication device body α30, spaced apart from each other on the left and right. Two engaging claws αF1 are provided at the upper end of the back plate α40, which engage with these two engaging recesses αf1. Multiple projections F2 are provided on the lower part of the rear surface of the authentication device body α30, projecting to the rear Rr. Multiple holes αf2a are provided in the back plate α40 through which these multiple projections αF2 are inserted, and which engage with these multiple projections αF2. The back plate α40 is attached to the rear surface of the authentication device body α30 by the engagement of these multiple projections F2 and the multiple holes αf2a, and by the engagement of the two engaging claws αF1 and the two engaging recesses αf1.

[0114] As shown in Figure 24, the first part of the back plate α61 is provided with multiple holes αf2b that engage with multiple protrusions αF2 of the authentication device body α30. Through the engagement of these multiple protrusions αF2 and the multiple holes αf2b, the back plate α60 is positioned relative to the rear surface of the authentication device α50, as shown in Figure 23. In this state, the authentication device α50 is housed inside the case α70. Two holes αf3c are provided side by side in the vertical direction at the lower part of the rear surface portion α716 of the first part of the case α71.

[0115] As shown in Figure 24, the upper part of the first back plate α61 is provided with two upper and lower holes αf3b that communicate with the two upper and lower holes αf3c of the rear surface portion α716 of the first case portion α71. The lower part of the first back plate α61 is also provided with two upper and lower holes αf3b. These two lower upper and lower holes αf3b are used when the back plate α60 is made to protrude to the left Lh from the authentication device α50, the opposite of the case in this embodiment. The back plate α40 is provided with two upper and lower holes αf3a that communicate with the two upper and lower holes αf3b at the top of the back plate α60. These two upper and lower holes αf3a of the back plate α40 are for housing the front end of the fastener F3 that is fastened to the two upper and lower holes f3b at the top of the back plate α60, and are larger than the two upper and lower holes αf3b at the top of the back plate α60.

[0116] As shown in Figure 23, the two fasteners αF3, such as screws or bolts, pass through the holes αf3c in the rear surface portion α716 of the first case portion α71 and are fastened to the holes αf2b in the back plate α60, thereby fixing the back plate α60 and the case α70 to the authentication device α50, as shown in Figure 22.

[0117] In the preparation step S1 shown in Figure 25, the wiring W2 inside the joinery α180 is connected to the wiring W1 of the authentication device α50 from the window α128. In the storage step S2, first, as shown in Figure 26, the fourth backing plate α64 and the third backing plate α63 of the authentication device unit α100 are inserted into the storage section α127 from the window α128. Then, as shown in Figure 27, the authentication device unit α100 is tilted so that the lower side is the rear Rr side and inserted into the storage section α127. Then, as shown in Figure 28, the right end of the backing plate α60 is fastened to the right vertical core material α124 of the sleeve section α120 with two fasteners F4, one above and one below.

[0118] Specifically, as shown in Figure 24, the upper and lower fourth sections α64 of the backing plate are each provided with α-holes f4b. As shown in Figure 28, the vertical core member α124 on the right side of the sleeve section α120 is provided with two upper and lower holes αf4a that communicate with the holes αf4b in the upper and lower fourth sections α64 of the backing plate. Each of these holes αf4a is an elongated hole extending in the front-to-back direction. The backing plate α60 is fastened to the vertical core member α124 by fastening two fasteners αF4, such as screws or bolts, through the holes αf4a in the vertical core member α124 and fastening them to the holes αf4b in the fourth section α64 of the backing plate.

[0119] The configuration and effects of this embodiment are summarized below.

[0120] As shown in Figure 1, the authentication device α50 is longer vertically than the window α128. The authentication device α50 consists of a first authentication device part α31 and a second authentication device part α38 arranged vertically. As a result, the authentication device α50 is housed in the storage section α127 in such a way that the first authentication device part α31 is visible from the front, while the second authentication device part α38 is not. Therefore, the appearance of the building fixture α180 with the authentication device is better than when the entire authentication device α50 is visible from the front.

[0121] As shown in Figure 28, the authentication device α50 has a back plate α60 attached to it that protrudes to the right Rh from the authentication device α50. The tip of the back plate α60 is fixed to the sleeve portion α120. As a result, the authentication device unit α100 can be simply fixed inside the storage portion α127.

[0122] As shown in Figure 26, the back plate α60 is mounted lower to the authentication device α50. Therefore, as shown in Figure 27, the authentication device unit α100 can be stored in the storage section α127 by passing it through the front of the window α128 Fr.

[0123] As shown in Figure 19, the authentication device unit α100 includes a case α70 that houses the authentication device α50 inside. The case α70 is provided with a case window α711 that allows the first part α31 of the authentication device to be seen through the window α128. Thus, the case α70 protects the authentication device α50 while the case window α711 allows the first part α31 of the authentication device to be seen. Furthermore, a flange α71p is provided in an annular shape in a front view on the portion of the case α70 located around the case window α711, projecting toward the opposite side of the case window α711. As shown in Figure 28, this flange α71p can conceal the gap between the authentication device unit α100 and the inner surface of the window α128.

[0124] Furthermore, when installing the authentication device unit α100 onto the joinery α150, the flange α71p prevents the authentication device unit α100 from being inserted too far into the storage compartment α127. Moreover, since the case α70 contains PC and ABS resin, there is no need to worry about the flange α71p being damaged even if the authentication device unit α100 is strongly pressed towards the rear Rr side during the installation process.

[0125] As shown in Figure 19, case α70 comprises a first case section α71 that houses the first authentication device section α31, and a second case section α78 that houses the second authentication device section α38. The first case section α71 protrudes forward Fr of the second authentication device section α38. By the length of this protrusion, the second authentication device section α38 can be positioned rear Rr of the window α128. As a result, the second authentication device section α38 can be efficiently housed in the storage section α127.

[0126] As shown in Figure 23, the authentication device α50 comprises an authentication device body α30 and a back plate α40 that abuts against the rear surface of the authentication device body α30. The back plate α60 abuts against the back plate α40. Therefore, the back plate α60 can be attached to the authentication device α50 using the back plate α40.

[0127] As shown in Figure 18, the storage section α127 and the window α128 are provided on the side section α120. Therefore, the authentication device α50 is attached to the side section α120. As a result, the appearance of the joinery α180 with the authentication device can be improved compared to when the authentication device α50 is attached to the door frame α110 or the door body α130.

[0128] As shown in Figure 27, in the storage process S2, the authentication device unit α100 is passed through the window α128 from the front Fr and stored in the storage section α127. As shown in Figure 28, in the subsequent fixing process S3, the tip of the backing plate α60 is fixed to the joinery α150. From the above, the authentication device unit α100 can be easily attached to the joinery α150.
