MODE FOR CARRYING OUT THE INVENTION

[0008] Hereinafter, embodiments of the present disclosure will be described with reference to the drawings. However, the present disclosure is not limited to the following embodiments and can be appropriately modified and implemented without departing from the gist of the present disclosure.

[0009] [First Embodiment] The joinery 80 shown in Figure 1 is installed between the interior and exterior of a room. The joinery 80 comprises a door frame 10, a door body 20, and a side panel 30. The door body 20 is installed inside the door frame 10 so as to be openable and closable. Unless otherwise specified, the positional relationships in the following description refer to the positional relationships when the door body 20 is closed.

[0010] Hereinafter, the exterior side of the door body 20 in the thickness direction will be referred to as "exterior side Y+", and the interior side of the door body 20 in the thickness direction will be referred to as "interior side Y-". Also, the leading edge side of the door body 20 in the width direction will be referred to as "leading edge side X+", and the trailing edge side of the door body 20 in the width direction will be referred to as "trailing edge side X-".

[0011] The side portion 30 is located inside the door frame 10, on the side of the door body 20, specifically on the leading edge side X+ of the door body 20. Hereinafter, an operation including at least one of unlocking and locking will be referred to as "lock operation".

[0012] The door 80 is configured to be lockable both contactlessly and electrically by providing a non-contact sensor 40 and an electric lock operating device 55. Specifically, the door 80 includes, as the non-contact sensor 40, an outdoor Y+ non-contact sensor 40o provided facing the outdoor Y+ as shown in Figure 1, and an indoor Y- non-contact sensor 40i provided facing the indoor Y- as shown in Figure 2. The door 80 also includes an upper electric lock operating device 55 and a lower electric lock operating device 55 as the electric lock operating device 55. However, there may be only one electric lock operating device 55. Note that "electric lock operating device 55" may be read as "predetermined part". A terminal 90 is provided for the door 80. The terminal 90 may be, for example, an operating terminal such as a remote key, or it may be any other terminal. The terminal 90 is carried by the user Ur of the door 80.

[0013] As shown in Figure 1, the outdoor non-contact sensor 40o is provided on the outdoor Y+ surface of the sleeve portion 30. As shown in Figure 2, the indoor non-contact sensor 40i is provided on the indoor Y- surface of the sleeve portion 30. Each non-contact sensor 40 is configured to detect objects such as a person's hand Hd without contact. Specifically, each non-contact sensor 40 is a radio wave sensor. That is, the non-contact sensor 40 emits radio waves, and when a user Ur holds their hand Hd over the non-contact sensor 40, it is detected without contact. When the non-contact sensor 40 detects an object such as a hand Hd, it transmits a detection signal S1, which is a predetermined wireless signal.

[0014] When terminal 90 receives a detection signal S1 from the non-contact sensor 40, it transmits a predetermined wireless signal, which is a command signal S2. When each of the upper and lower electric lock operating devices 55 receives the command signal S2 from terminal 90, it electrically unlocks the door 80.

[0015] Hereafter, the "lock operation triggered by the detection signal S1 from the non-contact sensor 40" as described above will simply be referred to as "non-contact lock operation." This non-contact lock operation is permitted, as described above, provided that the terminal 90 is within communication range of the designated equipment on the door / window 80 side. The "designated equipment on the door / window 80 side" referred to here is the "non-contact sensor 40 and the electric lock operating device 55."

[0016] As shown in Figure 3, an operating unit 60 is provided on the leading edge side of the door body 20, which allows the user to change settings related to contactless lock operation. Note that Figure 3 shows the door body 20 in a slightly open state. The settings related to contactless lock operation here include setting whether to enable or disable contactless lock operation, and setting the reaction distance of the contactless sensor 40. In other words, the operating unit 60 allows the user to select whether to enable or disable contactless lock operation, and to change the reaction distance of the contactless sensor 40.

[0017] Next, the joinery 80 of this embodiment, shown in Figure 1, will be described in more detail. The joinery 80 of this embodiment can be suitably implemented in nursing homes and care facilities. However, it may also be implemented in other buildings such as general residences.

[0018] The tail end X- of the door body 20 is rotatably attached to the door frame by hinges or the like. The side panel 30 may be a smaller door attached to the door frame 10 so as to be openable and closable, or it may be a fixed side panel attached to the door frame 10 so as not to be openable and closable. An exterior door handle 23 is attached to the exterior Y+ of the leading end X+ of the door body 20. Also, as shown in Figure 2, an interior door handle 27 is attached to the interior Y- of the leading end X+ of the door body 20. A door closer 28 is provided on the interior Y- of the upper part of the tail end X- of the door body 20.

[0019] A locking / unlocking unit 50 is provided in the sleeve portion 30. The locking / unlocking unit 50 includes an upper locking / unlocking unit 50u and a lower locking / unlocking unit 50d. The aforementioned upper electric lock operating device 55 is part of the upper locking / unlocking unit 50u, and the aforementioned lower electric lock operating device 55 is part of the lower locking / unlocking unit 50d. Specifically, each upper and lower locking / unlocking unit 50 comprises a locking / unlocking mechanism 54, a cylinder 53, a thumbturn 57, and the aforementioned electric lock operating device 55. The locking / unlocking mechanism 54 is configured to lock and unlock the door 80. The cylinder 53 is configured to allow manual operation of the locking / unlocking mechanism 54 using a key from the outside Y+. The thumbturn 57 is configured to allow manual operation of the locking / unlocking mechanism 54 from the inside Y-. The electric lock operating device 55 is configured to allow electric operation of the locking / unlocking mechanism 54. The electric lock operating device 55 locks the lock at a predetermined timing after the lock has been unlocked by contactless operation.

[0020] As shown in Figure 3, the operation unit 60 includes an upper display unit 63, a lower display unit 64, an upper switch 65, and a lower switch 66. The operation unit 60 is configured so that the numbers displayed on the upper display unit 63 can be changed by the upper switch 65, and the numbers displayed on the lower display unit 64 can be changed by the lower switch 66. Based on the operation of these upper switches 65 and lower switches 66, the operation unit 60 is configured so that the settings related to contactless lock operation can be changed as described above. If contactless lock operation is disabled by this operation unit 60, the electric lock operating device 55 will no longer receive the command signal S2, or will not operate the lock even if it receives the command signal S2.

[0021] The configuration and effects of this embodiment are summarized below.

[0022] The non-contact sensor 40 shown in Figure 1 is configured to detect objects, including a person's hand Hd, without physical contact, and transmits a detection signal S1 based on this non-contact detection. The electric lock operating device 55 uses the detection signal S1 as a trigger to electrically unlock the door 80. As a result, the user Ur can unlock the door 80 simply by holding their hand Hd over the non-contact sensor 40, without having to operate a remote key or anything similar for the door 80. Moreover, it is then automatically locked. Therefore, the operation of the lock on the door 80 is easy to use.

[0023] Contactless lock operation is permitted only if terminal 90 is within communication range of the electric lock operating device 55. Therefore, contactless lock operation is performed only when the person holding hand Hd is carrying terminal 90. This prevents outsiders from entering the indoor Y- from the outdoor Y+. It also prevents situations where a user Ur, etc., leaves the indoor Y+ from the indoor Y- without terminal 90 and gets locked out.

[0024] When terminal 90 receives a detection signal S1 from the non-contact sensor 40, it transmits a command signal S2. When the electric lock operating device 55 receives the command signal S2, it unlocks the door 80. Thus, a configuration that allows non-contact lock operation can be efficiently realized, provided that terminal 90 is within communication range with the equipment on the door 80 side. Moreover, terminal 90 only needs to transmit the command signal S2 when it receives the detection signal S1, so it does not need to transmit signals constantly. As a result, power consumption in terminal 90 is reduced.

[0025] The non-contact sensor 40 emits radio waves, and when the user Ur places their hand HD over the non-contact sensor 40, detection is performed without physical contact. This allows for efficient non-contact detection.

[0026] The non-contact sensor 40 is attached to the side panel 30. This improves the aesthetic design of the joinery 80.

[0027] The control unit 60 shown in Figure 3 is configured to allow the user to select whether to enable or disable contactless lock operation. Therefore, when the user Ur is away from the building for an extended period, security can be further enhanced by disabling contactless lock operation.

[0028] The control unit 60 is configured to allow the reaction distance of the non-contact sensor 40 to be changed. This allows the reaction distance of the non-contact sensor 40 to be adjusted to be just right. As a result, problems such as the door 80 being unlocked simply by a user Ur approaching the non-contact sensor 40, or the door 80 not being unlocked smoothly due to poor sensitivity even when a user Ur holds their hand Hd over the non-contact sensor 40, can be avoided.

[0029] The operating unit 60 is located on the leading edge side of the door body 20. This configuration allows only designated persons, such as those holding the terminal 90, to operate the operating unit 60, thus efficiently realizing such a configuration.

[0030] The non-contact sensor 40 includes an outdoor Y+ non-contact sensor 40o, which is provided facing the outdoor Y+ side as shown in Figure 1, and an indoor Y- non-contact sensor 40i, which is provided facing the indoor Y- side as shown in Figure 2. As a result, non-contact lock operation can be achieved from both the indoor Y- side and the outdoor Y+ side. Consequently, the operability of lock operation from both sides is good.

[0031] [Second Embodiment] Next, the second embodiment will be described with reference to Figure 4. This embodiment will be described based on the first embodiment, focusing on the differences, and explanations of points that are the same as or similar to the first embodiment will be omitted as appropriate.

[0032] In this embodiment, the non-contact sensors 40 are housed inside the sleeve portion 30 on both the outdoor side Y+ and the indoor side Y- so that they are not visible from the outside of the door 80. The location where the non-contact sensors 40 are housed in the sleeve portion 30 may be marked for clarity, or it may be left unmarked for security or aesthetic reasons.

[0033] According to this embodiment, the design of the building component 80 can be improved because the non-contact sensor 40 is not visible from the outside. Furthermore, the non-contact sensor 40 is a radio wave sensor. Therefore, compared to cases where the non-contact sensor 40 is an infrared sensor or the like, the decrease in detection sensitivity due to housing the non-contact sensor 40 inside the building component 80 can be reduced.

[0034] [Modified forms of the first and second embodiments] The above embodiments can be implemented with modifications, for example, as follows.

[0035] After unlocking by contactless operation, instead of the electric lock operating device 55 shown in Figure 1 locking at a predetermined timing, the following may be performed: When the lock is unlocked, if a hand Hd is held over the contactless sensor 40, the lock may be performed using the same mechanism as in the case of unlocking by contactless operation. Alternatively, contrary to the first and second embodiments, only locking may be triggered by a detection signal S1 from the contact sensor 40.

[0036] Either or both of the non-contact sensor 40o on the outdoor side Y+ shown in Figure 1 and the non-contact sensor 40i on the indoor side Y- shown in Figure 2 may be attached to the door body 20 or door frame 10 instead of the sleeve portion 30, or they may be provided outside the door frame 10. Furthermore, the non-contact sensor 40 may be provided only on either the outdoor side Y+ or the indoor side Y-. Specifically, for example, the non-contact sensor 40 may be provided only on the indoor side Y- shown in Figure 2, and an authentication device such as a facial recognition device may be provided on the outdoor side Y+ shown in Figure 1 instead of the non-contact sensor 40.

[0037] In this case, the door / window 80 may not have a terminal 90, and the detection signal S1 from the non-contact sensor 40 may also serve as the command signal S2. That is, in this case, non-contact lock operation is always permitted regardless of the presence or absence of the terminal 90. In this case, the detection signal S1, which also serves as the command signal S2, may be an electrical signal transmitted via wire from the non-contact sensor 40 to the electric lock operating device 55.

[0038] Terminal 90 may transmit a predetermined activation signal instead of the command signal S2. The non-contact sensor 40 may be configured to activate upon receiving the activation signal. In other words, the non-contact sensor 40 may be configured to activate only if terminal 90 is within communication range of the non-contact sensor 40. The detection signal S1 from the non-contact sensor 40 may also serve as the command signal S2 to the electric lock operating device 55. In this case as well, non-contact lock operation is permitted only if terminal 90 is within communication range of the predetermined device on the door / window 80 side. However, the "predetermined device on the door / window 80 side" here refers only to the "non-contact sensor 40," and not to the "non-contact sensor 40 and electric lock operating device 55."

[0039] In addition to or instead of the operating unit shown in Figure 3, settings related to contactless lock operation may be made possible from terminal 90 or other operating terminals. Also, terminal 90 shown in Figure 2 may be a remote key with an authentication key or the like. Furthermore, operating unit 60 shown in Figure 3 may be provided on the visible surface of the side portion 30 shown in Figure 2 on the door body 20 side (X-).

[0040] [Third Embodiment] Next, a third embodiment will be described with reference to Figures 5 to 30.

[0041] As shown in Figure 5, the joinery 100 is installed between the exterior So and the interior Si and is opened and closed electrically. The joinery 100 comprises a door frame 120, a first door body 130, and a second door body 140. Note that "first door body 130" and "second door body 140" may be read as "door body," respectively.

[0042] As shown in Figure 6, the door frame 120 includes a first vertical frame 121, an upper frame 123, a second vertical frame 122, and a lower frame 124. The first vertical frame 121 extends in the vertical direction. The second vertical frame 122 extends in the vertical direction at a position horizontally separated from the first vertical frame 121. The upper frame 123 connects the upper ends of the first vertical frame 121 and the second vertical frame 122. The lower frame 124 connects the lower ends of the first vertical frame 121 and the second vertical frame 122.

[0043] As shown in Figure 6, the first door body 130 is provided on the first vertical frame 121 side inside the door frame 120, and the second door body 140 is provided on the second vertical frame 122 side inside the door frame 120. The first door body 130 is configured to open and close on its end on the first vertical frame 121 side, and opens toward the exterior So side. The second door body 140 is configured to open and close on its end on the second vertical frame 122 side, and opens toward the exterior So side. Therefore, the joinery 100 is a double-opening door toward the exterior So side. Wall sections WL are provided on both sides of the joinery 100. Note that in Figure 6, the first door body 130 is provided relatively to the left and the second door body 140 is provided relatively to the right side when viewed from the interior Si, but conversely, the second door body 140 may be provided relatively to the left and the first door body 130 may be provided relatively to the right side.

[0044] In the following, as shown in Figure 5, the state in which both the first door body 130 and the second door body 140 are closed is referred to as the "closed state". In the following, the hinge side of the first door body 130 is referred to as the "hinged side D1a", and the leading edge side of the first door body 130 is referred to as the "leading edge side D1b". Similarly, the hinge side of the second door body 140 is referred to as the "hinged side D2a", and the leading edge side of the second door body 140 is referred to as the "leading edge side D2b".

[0045] First, the interior Si side portion of the door 100 will be described with reference to Figures 5 to 10. As shown in Figure 7, an airtight seal M is provided around the periphery of the first door body 130 to ensure airtightness between the first door body 130 and the surrounding area when it is closed. Here, "periphery of the first door body 130" includes the first vertical frame 121, the upper frame 123, the lower frame 124, and the second door body 140. Therefore, the airtight seal M is provided in the portions of the first vertical frame 121, the upper frame 123, the lower frame 124, and the second door body 140 that are adjacent to the first door body 130. In addition, an airtight seal M is also provided in the portions of the second vertical frame 122, the upper frame 123, and the lower frame 124 that are adjacent to the second door body 140, as shown in Figure 6. However, for example, between each of the first door panels 130 and the second door panel 140 and the bottom frame 124, a bottom shutter may be provided instead of the airtight material M. The bottom shutter is provided at the lower end of each door panel and is configured to lower in conjunction with the closing of the door panel.

[0046] As shown in Figure 9, the first door body 130 comprises a main part 131 and a sub-part 135. In the closed state, the leading edge D1b end of the main part 131 of the first door body 130 abuts against the airtight seal M of the second door body 140 from the exterior So side. Consequently, the interior Si side surface sf2 of the second door body 140 protrudes more towards the interior Si side than the interior Si side surface sf0 of the main part 131 of the first door body 130.

[0047] When viewed in the closed state, the sub-part 135 is provided on the interior Si side of the first door body 130, relative to the main part 131, and the interior Si side surface of the sub-part 135 constitutes the interior Si side surface sf1 of the first door body 130. Thus, as shown in Figure 10, in the closed state, the interior Si side surface sf1 of the first door body 130 and the interior Si side surface sf2 of the second door body 140 are located on the same virtual plane Vp.

[0048] As shown in Figure 7, the end of the hinge-side D1a in the sub-part 135 of the first door body 130 extends further into the door-edge side D1b than the end of the hinge-side D1a in the main part 131. As a result, in the closed state, a vertically extending gap GPa is formed between the sub-part 135 of the first door body 130 and the first vertical frame 121.

[0049] As shown in Figure 9, a handle 135H is provided at the interior Si side end of the door-edge side D1b of the sub-part 135 of the first door body 130, protruding toward the door-edge side D1b. When closed, a vertically extending gap GPb is formed between the handle 135H and the second door body 140. As shown in Figure 5, this handle 135H is provided over the entire vertical section of the first door body 130. This handle 135H is for manually closing the first door body 130, for example, when the door 100 cannot be closed electrically.

[0050] As shown in Figure 6, a non-contact sensor 40 for unlocking, opening, etc., is provided on the interior Si side. Similar to the first embodiment, when a user holds their hand in front of this non-contact sensor 40, it is detected without contact. In Figure 6, the non-contact sensor 40 is provided on the wall WL, but it may also be provided on the first door body 130 or the second door body 140. The non-contact sensor 40 may also be embedded in the wall WL, the first door body 130, or the second door body 140. In these cases, the non-contact sensor 40 may also be embedded in the electric lock 166 or the thumbturn.

[0051] Next, the exterior So side portion of the door 100 will be described with reference to Figures 9 to 17. As shown in Figure 9, the exterior So side portion of the second door body 140 is provided with a surface material 141o made of steel or aluminum plate. A window Wd is provided at a predetermined position on the surface material 141o, as shown in Figure 11. An operating part 161, as shown in Figure 13, is attached to the window Wd so as not to protrude beyond the surface material 141o towards the exterior So side. The operating part 161 is a part for users such as residents to perform unlocking operations and is equipped with a light-emitting part 161e that can emit light. Note that "operating part 161" may be read as "predetermined part". Hereinafter, as shown in Figure 14, the state in which the light-emitting part 161e is not emitting light will be called the "basic state StB", and as shown in Figure 15, the state in which the light-emitting part 161e is emitting light will be called the "light-emitting state StE".

[0052] As shown in Figure 16, an exterior part Le is provided on the portion of the first door body 130 that is located on the exterior So side of the surface material 141o. This exterior part Le includes a predetermined translucent plate L2 and a predetermined decorative sheet L1. These translucent plate L2 and decorative sheet L1 are provided over the entire exterior So side surface of the first door body 130 and the second door body 140 shown in Figure 9.

[0053] The translucent plate L2 shown in Figure 16 is made of an acrylic plate, glass plate, or the like, and is translucent. The decorative sheet L1 is a sheet decorated with a wood grain pattern or the like, and is provided along the surface of the translucent plate L2. However, instead, as shown in Figure 17, the decorative sheet L1 may be provided along the back surface of the translucent plate L2. This decorative sheet L1 also has enough translucency to transmit light from the light-emitting part 161e.

[0054] As shown in Figure 14, the operating unit 161 is embedded in the part of the second door body 140 that is behind the decorative sheet L1 when viewed from the outdoor So side, and in the basic state StB, it is not visible from the outdoor So side due to the decorative sheet L1.

[0055] On the other hand, when a person approaches the front of the control unit 161, the light illuminates in a state StE. A specific example of this is the detection of a person by means of a motion sensor. However, instead, as shown in Figure 15, a non-contact sensor 40 may also be provided on the outdoor So side. This non-contact sensor 40 is, for example, located on the control unit 161. The light illuminates in a state StE when the user places their hand over the non-contact sensor 40.

[0056] In the illuminated state StE, light from the light-emitting unit 161e passes through the translucent plate L2 and the decorative sheet L1. As a result, information such as numbers for unlocking operations is displayed on the surface of the decorative sheet L1. This operation unit 161 is configured to be touch-operable, for example, by a capacitive touch sensor. As a result, it is configured to allow input of a PIN or the like.

[0057] Therefore, as shown in Figure 15, if a non-contact sensor 40 is provided on the outdoor So side, the operation unit 161 will display information for performing the unlocking operation, triggered by a detection signal from the non-contact sensor 40.

[0058] Next, the structure related to the opening and closing of the door 100 described above will be explained with reference to Figures 6, 9 and 19 to 28. As shown in Figure 9, a projection 131b is provided at the end of the leading edge D1b of the first door body 130 on the exterior So side. In the closed state, this projection 131b is located on the exterior So side of the leading edge D2b of the second door body 140. Therefore, when the first door body 130 is closed in this way, the second door body 140 cannot be opened from the closed state. Furthermore, when the first door body 130 is closed in this way, the second door body 140 cannot be completely closed from the open state.

[0059] As shown in Figure 6, the second door body 140 is provided with a fixing mechanism 156 and an interlocking mechanism 151. In this embodiment, the fixing mechanism 156 is a French bolt. In the closed state, the fixing mechanism 156 is configured to fix the second door body 140 in the closed position. When the first door body 130 begins to open from the closed state shown in Figure 23, as shown in Figure 24, the fixing mechanism 156 is activated by the interlocking mechanism 151, and the fixing of the second door body 140 by the fixing mechanism 156 is released. Also, as shown in Figure 27, when the first door body 130 is open and the second door body 140 is closed, as shown in Figure 28, when the first door body 130 is closed, the fixing mechanism 156 is activated by the interlocking mechanism 151, and the second door body 140 is fixed by the fixing mechanism 156.

[0060] As shown in Figure 22, the door / window 100 includes, in addition to the aforementioned operating unit 161 and non-contact sensor 40, a control device 165, an electric lock 166, a first detection device 163, a second detection device 164, a first opening / closing device 167, and a second opening / closing device 168.

[0061] The first opening / closing device 167 shown in Figure 19 is configured to electrically open and close the first door body 130. On the other hand, the second opening / closing device 168 is configured to electrically open and close the second door body 140. The first detection device 163 shown in Figure 22 detects the degree to which the first door body 130 is open or closed. On the other hand, the second detection device 164 detects the degree to which the second door body 140 is open or closed.

[0062] The control device 165 shown in Figure 22 performs the following operations when a predetermined unlocking operation is correctly performed by the operating unit 161 from the outdoor So side, or when a hand is placed in front of the non-contact sensor 40 on the indoor Si side. Specifically, first, the electric lock 166 is unlocked. Then, the door 100 is opened using the first opening / closing device 167 and the second opening / closing device 168. After a predetermined time has elapsed, the door 100 is closed using the first opening / closing device 167 and the second opening / closing device 168. After that, the electric lock 166 is locked.

[0063] Next, we will explain the "door opening control" as a control method for opening the door 100 by the control device 165. In door opening control, the opening of the first door body 130 is started as shown in Figure 24, and then the opening of the second door body 140 is started as shown in Figure 25. Specifically, if the opening of the first door body 130 shown in Figure 24 is not confirmed by the first detection device 163, the control device 165 will not start opening the second door body 140. After the opening of the first door body 130 is confirmed by the first detection device 163, the opening of the second door body 140 is started as shown in Figure 25. Thus, as described above, the opening of the first door body 130 is started, followed by the opening of the second door body 140.

[0064] Next, we will explain the "door closing control" as a control method for opening the door 100 by the control device 165. In door closing control, as shown in Figure 27, the closing of the second door body 140 is completed first, and then as shown in Figure 28, the closing of the first door body 130 is completed. Specifically, if the completion of the closing of the second door body 140 shown in Figure 27 is not detected by the second detection device 164, the control device 165 pauses the closing operation of the first door body 130. This prevents the closing of the first door body 130 from progressing to completion. Subsequently, if the completion of the closing of the second door body 140 is detected by the second detection device 164, the pause is released, and the closing of the first door body 130 proceeds to completion, as shown in Figure 28. This ensures that, as described above, the closing of the second door body 140 is completed first, followed by the closing of the first door body 130.

[0065] Next, we will provide further details about this embodiment.

[0066] As shown in Figure 5, the electric lock 166 is attached, for example, to the second door body 140.

[0067] As shown in Figure 8 in the closed state, a projection 131a is provided at the end of the hinge side D1a of the first door body 130, on the side facing the exterior So. This projection 131a protrudes toward the adjacent wall WL side. As viewed from the exterior So side, a hinge 139 is provided behind the projection 131a. The first door body 130 is attached to the first vertical frame 121 so that it can be opened and closed by this hinge 139.

[0068] Similarly, as shown in Figure 21, when viewed in the closed state, a projection 141a is provided at the end of the hinge side D2a of the second door body 140 on the outdoor So side. This projection 141a protrudes toward the adjacent wall WL side. When viewed from the outdoor So side, a hinge 149 is provided behind the projection 141a. The second door body 140 is attached to the second vertical frame 122 so that it can be opened and closed by this hinge 149.

[0069] As shown in Figure 9, surface materials 131o and 131i are provided on the exterior So side and interior Si side portions of the main part 131 of the first door body 130. An insulating material (not shown) is interposed between these two surface materials 131o and 131i. The sub-part 135 of the first door body 130 is a single plate in Figure 9, but it may be composed of multiple members. Specifically, for example, the sub-part 135 may include a plate-like portion (not shown) that constitutes the surface portion on the interior Si side, and an interposing portion (not shown) interposed between the plate-like portion and the main part 131. The interposing portion is provided in the shape of a frame that extends along the edge of the plate-like portion. The interior Si side end of the sub-part 135 at the door edge side D1b protrudes outwards from the door edge side D1b, thereby forming the handle 135H.

[0070] The second door body 140, like the first door body 130, comprises a main part 141 and a sub-part 145. Surface materials 141o and 141i are also provided on the exterior So side and interior Si side portions of the main part 141 of the second door body 140, similar to the first door body 130. Insulation material (not shown) is interposed between these two surface materials 141o and 141i. The window Wd shown in Figure 13 is provided on the exterior So side surface material 141o.

[0071] In Figure 9, the sub-part 145 of the second door body 140 is also a single plate, but it may be composed of multiple members. Specifically, for example, the sub-part 145 of the second door body 140 may also include a plate-like portion (not shown) that constitutes the surface portion on the interior Si side, and an interposing portion (not shown) interposed between the plate-like portion and the main part 131.

[0072] As shown in Figure 7, when viewed in the closed state, a projection 121b is provided on the portion of the first vertical frame 121 located to the side of the sub-part 135 of the first door body 130, projecting toward the first door body 130. When viewed from the interior Si side, an airtight seal M is installed behind this projection 121b. Similarly, when viewed in the closed state as shown in Figure 21, a projection 122b is provided on the portion of the second vertical frame 122 located to the side of the sub-part 145 of the second door body 140, projecting toward the second door body 140. When viewed from the interior Si side, an airtight seal M is installed behind this projection 122b. In the same manner as these, an airtight seal M is also provided between the upper frame 123, the lower frame 124 and the first door body 130, and between the upper frame 123, the lower frame 124 and the second door body 140, as shown in Figure 6.

[0073] As shown in Figure 9, when viewed in the closed state, the end of the secondary part 145 of the second door body 140 on the door edge side D2b, on the interior Si side, is provided with a projection 145b that protrudes toward the first door body 130. More specifically, as shown in Figure 9, the portion of the secondary part 145 of the second door body 140 that does not include the projection 145b may be attached to the portion that does not include the projection 145b, or, unlike in Figure 9, the projection 145b may be integrally formed with the secondary part 145. When viewed from the interior Si side, an airtight seal M is provided behind the projection 145b. Also, when viewed from the exterior So side, an airtight seal M is provided in the portion of the second door body 140 that is located behind the projection 131b of the first door body 130.

[0074] As shown in Figure 19, the first opening / closing device 167 is embedded in the upper part of the first door body 130. The second opening / closing device 168 is embedded in the upper part of the second door body 140. However, alternatively, the first opening / closing device 167 may be provided outside the first door body 130, and the second opening / closing device 168 may be provided outside the second door body 140.

[0075] The configuration and effects of this embodiment are summarized below. First, referring to Figures 5 to 10, the configuration and effects of the interior Si-side portion of the joinery 100 are summarized.

[0076] As shown in Figure 9, the main part 131 of the first door body 130 abuts against the airtight material M of the second door body 140 from the exterior So side when it is closed. Consequently, the interior Si side surface sf2 of the second door body 140 protrudes more towards the interior Si side than the interior Si side surface sf0 of the main part 131 of the first door body 130. Therefore, if the interior Si side surface sf0 of the main part 131 were the interior Si side surface of the first door body 130, a step would be created between the interior Si side surfaces sf0 and sf2 of the first door body 130 and the second door body 140. This could potentially degrade the aesthetic appearance of the interior Si side of the joinery 100.

[0077] In this embodiment, as shown in Figure 9, when viewed in the closed state, the first door body 130 has a sub-part 135 on the interior Si side of the main part 131. The interior Si side surface of the sub-part 135 constitutes the interior Si side surface sf1 of the first door body 130. As a result, the difference in height between the interior Si side surfaces sf1 and sf2 of the first door body 130 and the second door body 140 can be reduced, improving the aesthetic appearance of the interior Si side of the joinery 100.

[0078] In particular, in this embodiment, as shown in Figure 10, when the door is closed, the interior Si-side surface sf1 of the first door body 130 and the interior Si-side surface sf2 of the second door body 140 are located on the same virtual plane Vp. As a result, the step difference can be completely eliminated, and the aesthetic appearance can be particularly improved.

[0079] Furthermore, as shown in Figure 9, a handle 135H is formed on the interior Si side end of the door-edge side D1b of the sub-part 135 of the first door body 130, protruding toward the door-edge side D1b. When the door is closed, a gap GPb is formed between the handle 135H and the second door body 140. As a result, the user can grasp the handle 135H through this gap GPb. By forming the handle 135H in a recessed manner in this way, the handle 135H can be made less conspicuous compared to, for example, when the handle 135H is formed to protrude toward the interior Si side. This also improves the aesthetic appearance of the interior Si side of the joinery 100.

[0080] As shown in Figure 7, the end of the hinge-side D1a in the sub-part 135 of the first door body 130 extends further into the door-edge side D1b than the end of the hinge-side D1a in the main part 131. As a result, when the door is closed, a vertically extending gap GPa is formed between the end of the hinge-side D1a in the sub-part 135 of the first door body 130 and the first vertical frame 121. Therefore, even if an object placed in the entrance gets caught between the end of the hinge-side D1a in the sub-part 135 of the first door body 130 and the first vertical frame 121 when closing the first door body 130, there is no risk of it getting pinched. This prevents damage to the object or the first door body 130.

[0081] As shown in Figure 5, the handle 135H is formed along the entire vertical section of the first door body 130. Therefore, users can grip the handle 135H at any point in the vertical direction of the first door body 130. This means that people of all ages, from children to adults, can grip the handle 135H without difficulty.

[0082] Next, referring to Figures 9 to 17, we will summarize the configuration and effects of the exterior So side portion of the door / window 100.

[0083] As shown in Figure 14, when viewed from the exterior So side, the operating unit 161 is embedded in the part of the first door body 130 that is located behind the decorative sheet L1. Therefore, in the basic state StB shown in Figure 14, the operating unit 161 is not visible from the exterior So side due to the decorative sheet L1. This improves the aesthetic appearance of the exterior So side of the joinery 100. Moreover, in the illuminated state StE shown in Figure 15, information such as numbers for unlocking is displayed on the decorative sheet L1 by light passing through the decorative sheet L1.

[0084] Based on the above, in the basic state StB shown in Figure 14, the aesthetics of the outdoor So side are ensured by concealing the operation unit 161 and the information, while in the illuminated state StE shown in Figure 15, the functionality of the operation unit 161 is ensured by making the information visible. Moreover, in the illuminated state StE, the information is displayed as if it were floating on the decorative sheet L1. This enhances the aesthetics and sense of luxury in the illuminated state StE. Furthermore, since the information for unlocking is not displayed on the operation unit 161 unless an action such as approaching the operation unit 161 or placing a hand over the non-contact sensor is performed, security is also improved.

[0085] As shown in Figure 16, a light-transmitting plate L2 is provided in front of the operating section 161. A decorative sheet L1 is provided along the surface of the light-transmitting plate L2, or along the back surface of the light-transmitting plate L2, as shown in Figure 17. This allows the decorative sheet L1 to be positioned neatly and easily in front of the operating section 161.

[0086] As shown in Figure 9, the translucent panel L2 and decorative sheet L1 are provided across the entire surface of the first door body 130 and the second door body 140. Therefore, compared to, for example, the case where the translucent panel L2 and decorative sheet L1 are only in front of the operating section 161 as shown in Figure 15, the incongruity between the area in front of the operating section 161 and its surroundings is eliminated, and the aesthetic appearance of the exterior So side of the door 100 can be further improved.

[0087] As shown in Figure 13, the second door body 140 is equipped with a surface material 141o made of steel or aluminum plate. The surface material 141o is equipped with a window Wd. An operating unit 161 is installed in the window Wd. This allows the operating unit 161 to be seamlessly embedded in the second door body 140.

[0088] Next, referring to Figures 6, 9, and 19-28, we will summarize the configuration and effects of opening and closing the door 100.

[0089] As shown in Figure 29, the first door body 130 is configured to open and close around the end opposite to the second door body 140. The second door body 140 is configured to open and close around the end opposite to the first door body 130. In other words, the door 100 is double-opening. As a result, as shown in Figure 29, when user Ur is on the outdoor So side, which is the opening side of the door 100, the distance Ds that user Ur must move back to a position where it does not interfere with the door 100 is smaller than when the door 100 is single-opening, as in the comparative example shown in Figure 30. Therefore, the burden on user Ur to move back to a position where it does not interfere with the door 100 can be reduced.

[0090] As shown in Figure 9, there is a protrusion 131b, so when the first door body 130 is closed, the second door body 140 cannot be opened from the closed position. In this regard, the door opening control starts opening the first door body 130 as shown in Figure 24, and then starts opening the second door body 140 as shown in Figure 25. Therefore, even when there is a protrusion 131b as shown in Figure 9, the system can handle this without any problems.

[0091] Furthermore, if the first door body 130 closes before the second door body 140 from the state shown in Figure 26, the second door body 140 will not be able to close completely due to the protrusion 131b shown in Figure 9. In contrast, the door closing control completes the closing of the second door body 140 as shown in Figure 27, and then completes the closing of the first door body 130 as shown in Figure 28. Therefore, even when there is a protrusion 131b as shown in Figure 9, the system can handle the situation without any problems.

[0092] The fixing mechanism 156 shown in Figure 6 is configured to fix the second door body 140 in a closed position when it is closed. When the first door body 130 begins to open from its closed position as shown in Figure 24, the interlocking mechanism 151 releases the fixing of the second door body 140 by the fixing mechanism 156 in conjunction with the opening of the first door body 130. This allows the release of the fixing of the second door body 140 by the fixing mechanism 156 to be performed automatically and smoothly in conjunction with the closing of the first door body 130.

[0093] Furthermore, as shown in Figure 27, when the second door body 140 is closed, the interlocking mechanism 151, when the first door body 130 is closed as shown in Figure 28, is linked to the fixing mechanism 156 in fixing the second door body 140. This allows the fixing mechanism 156 to fix the second door body 140 automatically and smoothly in conjunction with the closing of the first door body 130.

[0094] The control device 165 shown in Figure 22, in door opening control, will not start opening the second door body 140 if the start of opening of the first door body 130 shown in Figure 24 is not confirmed by the first detection device 163. Therefore, for example, in a situation where the first door body 130 is being held down by the user for certain reasons and cannot be opened, the problem of trying to forcibly open the second door body 140 can be avoided.

[0095] Furthermore, in door closing control, if the second detection device 164 does not confirm that the second door body 140 shown in Figure 27 has completed closing, the control device 165 will not proceed to the completion of closing the first door body 130. This avoids problems such as the first door body 130 being closed first, preventing the second door body 140 from being completely closed, for example, if the second door body 140 is being held down by the user for certain reasons and cannot be closed.

[0096] [Modified form of the third embodiment] The above embodiments can be implemented with modifications, for example, as follows.

[0097] The handle 135H may be formed in only a portion of the height range of the main body of the door / window 100 shown in Figure 6.

[0098] A handle may be provided on the exterior side of the first door body 130 shown in Figure 11. The operating unit 161 may be embedded in the handle. Alternatively, the operating unit 161 may be embedded in the first door body 130, the door frame 120, or the wall WL instead of the second door body 140.

[0099] Instead of the decorative sheet L1 shown in Figures 16 and 17, a painted portion may be provided on the front or back surface of the translucent plate L2.

[0100] As shown in Figure 18, the light-emitting section 161e may be provided in an area that includes all of the multiple light-emitting sections 161e shown in Figure 15. Furthermore, as shown in Figure 18, a light-shielding sheet L3 having light-blocking properties may be provided on the outdoor So side of the light-emitting section 161e. The light-shielding sheet L3 may be provided with holes L3h in the shape of the light-emitting section 161e shown in Figure 15. Note that, as viewed from the outdoor So side, the light-shielding sheet L3 may be provided behind the light-transmitting plate L2, as shown in Figure 18, or conversely, it may be provided in front of the light-transmitting plate L2.

[0101] As shown in Figure 26, the door 100 may be made to open towards the interior Si side instead of opening towards the exterior So side. Furthermore, in the first door body 130 and the second door body 140, sub-parts 135, 145, etc. may be provided on the exterior So side of the main parts 131, 141, respectively, and the structure on the exterior So side of the main parts 131, 141 may be provided on the interior Si side.

[0102] Instead of operating the control unit 161 shown in Figure 12, the door 100 may be unlocked, opened, etc., based on the operation of a remote control key. Alternatively, instead of the control unit 161, a notification device that provides an answer-back when the door 100 is unlocked may be provided. In this case, the notification device will light up when the door 100 is unlocked. In this illuminated state, the light transmitted through the translucent plate L2 and the decorative sheet L1 will display answer-back information on the surface of the decorative sheet L1.

[0103] Instead of the operating unit 161 shown in Figure 12, an authentication device 161F equipped with a camera 161f as shown in Figure 31 may be provided. In this case, the camera 161f acquires information such as facial information of a person outside So based on the light transmitted through the light-transmitting plate L2 and the decorative sheet L1. The authentication device 161F performs authentication based on that information. The control device 165 controls the locking and opening of the door 100 based on the authentication.

[0104] An operating unit similar to the operating unit 161 shown in Figure 15 may also be provided on the interior Si side as shown in Figure 5, and a decorative sheet may be provided in front of it. This operating unit is, for example, used to change settings such as the opening and closing speed and opening time of the door 100. Furthermore, a non-contact sensor other than the aforementioned non-contact sensor 40 may be provided on the interior Si side. When a hand is placed over this other non-contact sensor, information for changing the setting may be displayed on the decorative sheet by the operating unit.

[0105] As shown in Figure 32, the second door body 140 may be omitted, and the joinery 100 may be made into a single-leaf door where only the first door body 130 opens. [Explanation of symbols]
