[0008] The embodiments of the building components described herein will be explained below with reference to Figures 1 to 9. The embodiments described below represent one aspect of the disclosure and are not limiting, and can be modified at will within the scope of the technical concept of the disclosure. In addition, the scale of each component in the following drawings differs from that of the actual structure in order to make the components easier to understand.

[0009] [First embodiment of joinery] The overall configuration of the joinery 1 will now be described. As shown in Figure 1, the joinery 1 comprises a frame 2 attached to an opening 1A formed in the wall of a building, sliding screens 10A, 10B and a screen door 20 that can slide horizontally on the frame 2, and an interlocking device 30. The frame 2 has an upper frame 3, a lower frame 4, and left and right vertical frames 5, and is formed in the shape of a rectangular frame.

[0010] In the following description of the joinery 1 installed in a building opening, viewed from the inside, the vertical direction is referred to as the vertical direction, and the horizontal direction as the horizontal direction. The direction perpendicular to the horizontal direction and aligned with the indoor / outdoor direction is referred to as the depth direction.

[0011] The joinery 1 consists of an inner shoji screen 10A and an outer shoji screen 10B, both housed within the frame 2 in the depth direction, for opening and closing the opening 1A. The shoji screen 10A is located on the indoor side, and the shoji screen 10B is located on the outdoor side, opening and closing the opening 1A horizontally. The shoji screens 10A and 10B are sliding shoji screens.

[0012] Shoji screens 10A and 10B each have an upper frame 11, a lower frame 12, and left and right vertical frames 13 and 14, and are formed in a rectangular frame shape. The vertical frame 14 in shoji screen 10A corresponds to the door-edge frame located on the door-edge side of shoji screen 10A. In the following description, the vertical frame 14 in shoji screen 10A will be referred to as the door-edge frame 14. In Figure 1, the illustration of the vertical frame 14 in shoji screen 10B is omitted. Inside shoji screens 10A and 10B, for example, glass is housed.

[0013] The screen door 20 is positioned on the exterior side of the shoji screen 10B. The screen door 20 is slidable in the left-right direction. The screen door 20 can face the shoji screens 10A and 10B in the depth direction. The screen door 20 has an upper frame 21, a lower frame 22, and left and right vertical frames 23 and 24, and is formed in a rectangular frame shape.

[0014] The interlocking device 30 can link the opening of the screen door 20 to the opening of the sliding door 10A, and can also link the closing of the screen door 20 to the closing of the sliding door 10A. The interlocking device 30 can be switched between being linked and not linked to the opening and closing of the sliding door 10A and the opening and closing of the screen door 20 by operating the operating unit 38.

[0015] As shown in Figure 2, the interlocking device 30 includes a device main body 31, a magnet 32, and a magnetic body 33. The device main body 31 is provided on the leading stile 14 of the shoji 10A. The magnet 32 corresponds to a connecting member. The magnet 32 is provided on one of the shoji 10A and the screen door 20. The magnetic body 33 corresponds to a member to be connected. The magnetic body 33 is provided on the other of the shoji 10A and the screen door 20. The magnet 32 is provided on the device main body 31 disposed on the shoji 10A. The magnetic body 33 is provided on the indoor side of the vertical stile 24 of the screen door 20. As will be described later, the magnet 32 and the magnetic body 33 are separated from each other when the operating portion 38 is at the first position P1. The magnet 32 and the magnetic body 33 are brought into a connected state when the operating portion 38 is at the second position P2.

[0016] As shown in Figures 2 and 3, the device main body 31 includes a fixing member 35, a moving member 36, a link mechanism 37, and an operating portion 38. The fixing member 35 is disposed inside the vertical stile 14. The fixing member 35 is in the shape of a square cylinder extending in the left-right direction. The fixing member 35 is fixed to the vertical stile 14 at both ends in the left-right direction. The fixing member 35 has a long groove 35A penetrating in the up-down direction and extending in the left-right direction, a long groove 35B penetrating in the depth direction and extending in the left-right direction, and a long groove 35C penetrating in the depth direction and extending in the left-right direction.

[0017] The moving member 36 is provided on the outdoor side relative to the vertical stile 14 and on the indoor side relative to the vertical stile 24 of the screen door 20. The moving member 36 has a U-shape in a cross section orthogonal to the left-right direction, opening toward the indoor side. On the outdoor side of the moving member 36, the magnet 32 is fixedly provided at a position facing the magnetic body 33.

[0018] The link mechanism 37 includes links 39, 40 and joints 41, 42, 43, 44. The joint 41 is a shaft extending in the vertical direction and is provided on the right side of the fixed member 35. The joint 42 is a shaft extending in the vertical direction and is provided on the left side of the moving member 36. The joint 43 is a shaft extending in the vertical direction and is provided on the left side of the fixed member 35 relative to the joint 41. The joint 43 is fitted into the long groove 35A of the fixed member 35 so as to be movable in the left-right direction. The joint 44 is a shaft extending in the vertical direction and is provided on the right side of the moving member 36 relative to the joint 42.

[0019] The link 39 and the link 40 are each in the form of a flat plate extending linearly, and are arranged to cross in an X shape when viewed in the vertical direction. The link 39 is arranged on the upper side, and the link 40 is arranged on the lower side.

[0020] An indoor-side end of the link 39 is inserted into the fixed member 35 through the long groove 35C. The link 39 is rotatably coupled to the joint 41 at the indoor-side end thereof. An outdoor-side end of the link 39 is inserted into the moving member 36 through the opening. The link 39 is rotatably coupled to the joint 42 at the outdoor-side end thereof.

[0021] An indoor-side end of the link 40 is inserted into the fixed member 35 through the long groove 35C. The link 40 is rotatably coupled to the joint 43 at the indoor-side end thereof. An outdoor-side end of the link 40 is inserted into the moving member 36 through the opening. The link 40 is rotatably coupled to the joint 44 at the outdoor-side end thereof.

[0022] The operating section 38 extends in the depth direction. The outdoor end of the operating section 38 is inserted into the interior of the fixing member 35 from the long groove 35B. The operating section 38 is connected to the joint 43 at its outdoor end in a state where it is rotatable and maintains an orientation extending in the depth direction. The indoor end of the operating section 38 protrudes and is exposed to the indoor side from the long groove 14A that extends in the left-right direction and is formed in the indoor wall portion of the vertical frame 14.

[0023] As shown in Figure 4, when the operating unit 38 of the above-described interlocking device 30 is in the first position P1 to the left of the long groove 14A, which is further to the left than the position shown in Figure 2, the link mechanism 37 moves the joints 42 and 44, which are connected to the outdoor ends of links 39 and 40, to the indoor side as the distance in the left-right direction between joints 41 and 43, which are connected to the indoor ends of links 39 and 40, increases. As joints 42 and 44 move to the indoor side, the moving member 36 and the magnet 32 ​​move to the indoor side in the depth direction. As the magnet 32 ​​moves to the indoor side in the depth direction, the magnet 32 ​​and the magnetic material 33 can be separated. As the magnet 32 ​​separates from the magnetic material 33, the connection between the sliding door 10A and the screen door 20 is released, so the opening and closing of the sliding door 10A and the opening and closing of the screen door 20 can be made unlinked.

[0024] When the operating unit 38 is operated to move it to the second position P2 in the long groove 14A, which is to the right of the first position P1 shown in Figure 4, as shown in Figure 2, in the link mechanism 37, the distance in the left-right direction between joints 41 and 43, which are connected to the indoor ends of links 39 and 40, becomes shorter, causing joints 42 and 44, which are connected to the outdoor ends of links 39 and 40, to move to the outdoor side. As joints 42 and 44 move to the outdoor side, the moving member 36 and the magnet 32 ​​move to the outdoor side in the depth direction. As the magnet 32 ​​moves to the outdoor side in the depth direction, the magnet 32 ​​and the magnetic material 33 can be brought into contact. As the magnet 32 ​​comes into contact with the magnetic material 33, the magnet 32 ​​and the magnetic material 33 become magnetically attached, and the shoji screen 10A and the screen door 20 become connected, allowing the shoji screen 10A and the screen door 20 to move together as a single unit. Because the shoji screen 10A and the screen door 20 can be moved as a single unit, the opening and closing of the shoji screen 10A and the opening and closing of the screen door 20 can be synchronized.

[0025] In the building fixture 1 of this embodiment, by switching the position of the operating unit 38 between a first position P1 and a second position P2, it becomes possible to easily switch between the opening and closing of the sliding door 10A and the opening and closing of the screen door 20, which face each other in the depth direction, between non-interlocking and interlocking.

[0026] In the building fixture 1 of this embodiment, the second position P2 is positioned away from the first position P1 in the opening and closing direction of the sliding door 10A and the screen door 20. As a result, the operating direction for switching between the non-interlocking and interlocking of the sliding door 10A and the screen door 20 is the same as the opening and closing direction of the sliding door 10A and the screen door 20, allowing the operating direction to be selected without hesitation when operating the operating unit 38.

[0027] [Second embodiment of the joinery] A second embodiment of the joinery will be described with reference to Figures 5 to 8. In these figures, elements identical to those in the first embodiment shown in Figures 1 to 4 are denoted by the same reference numerals, and their descriptions are omitted.

[0028] As shown in Figures 6 and 7, the sliding door 10B includes an interlocking device 30 having an operating unit 38, a lock operating unit 45, and a sliding door operating unit 50. The interlocking device 30, the lock operating unit 45, and the sliding door operating unit 50 are arranged sequentially from bottom to top on the indoor side surface 13A of the door frame 13.

[0029] The interlocking device 30 is installed inside the door frame 13. The second position P2 of the operating unit 38, which interlocks the opening and closing of the sliding door 10A with the opening and closing of the screen door 20, is positioned lower in the vertical direction than the first position P1 of the operating unit 38, which decouples the opening and closing of the sliding door 10A from the opening and closing of the screen door 20. The operating direction of the operating unit 38 for switching between interlocking and decoupling the opening and closing of the sliding door 10A and the opening and closing of the screen door 20 is vertical.

[0030] As shown in Figure 8, the door frame 13 has a locking mechanism 60 that can protrude to the left. The locking mechanism 60 locks the sliding door 10B when it protrudes from the door frame 13 and unlocks the sliding door 10B when it retracts into the door frame 13. The locking mechanism 45 is located at the position of the locking mechanism 60 in the vertical direction. The locking mechanism 45 is movable in the left-right direction. For example, when the locking mechanism 45 is moved to the left, it moves the locking mechanism 60 to the locked position, and when it is moved to the left, it moves the locking mechanism 60 to the unlocked position.

[0031] The shoji screen operating unit 50 allows the shoji screen 10B to be opened and closed independently when operated. The shoji screen operating unit 50 is operated when opening and closing the shoji screen 10B in a state independent of the screen door 20.

[0032] In the door 1 of this embodiment, the interlocking device 30, the lock operating unit 45, and the sliding door operating unit 50 are all located on the surface 13A of the door frame 13, thus shortening the operation time. In the door 1 of this embodiment, the operating direction of the operating unit 38 is vertical, which allows the left-right dimension of the door frame 13 to be shortened and made thinner.

[0033] [Third embodiment of joinery] A third embodiment of the joinery will be described with reference to Figure 9. In this figure, elements identical to those in the second embodiment shown in Figures 5 to 8 are denoted by the same reference numerals, and their descriptions are omitted.

[0034] In the third embodiment of the building fixture 1, as shown in Figure 9, a motor 70, an operating switch 71, a lock operating switch 72, and a control unit CONT are provided. When the motor 70 is driven under the control of the control unit CONT, it can switch between the first position P1 and the second position P2 of the operating unit 38 in the interlocking device 30. When the motor 70 is driven under the control of the control unit CONT, it can switch between locking and unlocking the lock unit 60 in the lock operating unit 45.

[0035] The control unit switch 71 outputs an operation signal to the control unit CONT when the control unit 38 is operated. For example, the control unit switch 71 can be configured to use two switches, "interlocked" and "non-interlocked," and output the signal of the selected switch to the control unit CONT, or it can be configured to use a "switch" switch as the control unit switch 71, and when selected, switch the state before the switch selection to another state.

[0036] The lock operation switch 72 outputs an operation signal to the control unit CONT when the lock operation unit 45 is operated. For example, the lock operation switch 72 can be configured to use two switches, "lock" and "unlock," and output the signal of the selected switch to the control unit CONT, or it can be configured to use a "switch" switch as the lock operation switch 72, and when selected, switch the state before the switch selection to another state.

[0037] The control unit CONT drives the motor 70 based on the signal output from the operation switch 71 to switch the operation unit 38 in the interlocking device 30 between the first position P1 and the second position P2. The control unit CONT drives the motor 70 based on the signal output from the lock operation switch 72 to switch the lock unit 60 in the lock operation unit 45 between locking and unlocking.

[0038] In the building fixture 1 of this embodiment, when switching between "interlocked" and "non-interlocked" states of the interlocking device 30 and switching between "locked" and "unlocked" states of the lock unit 60 is performed electrically, the interlocking device 30 and the lock operating unit 45 are located together, making it easy to construct a switching system.

[0039] Preferred embodiments of this disclosure have been described above with reference to the attached drawings, but it goes without saying that this disclosure is not limited to these examples. The shapes and combinations of the components shown in the above examples are just examples and can be modified in various ways based on design requirements, etc., without departing from the spirit of this disclosure.

[0040] For example, in this embodiment, the interlocking device 30 is provided on the door frame 14, but the configuration is not limited to this. The interlocking device 30 may also be provided on either the upper frame 11 or the lower frame 12.

[0041] In this embodiment, a configuration in which the magnet 32 ​​is provided on the shoji screen 10A and the magnetic material 33 is provided on the screen door 20 is illustrated, but the configuration is not limited to this. A configuration in which the magnet 32 ​​is provided on the screen door 20 and the magnetic material 33 is provided on the shoji screen 10A is also possible.

[0042] In this embodiment, the connecting member is a magnet 32 ​​and the connected member is a magnetic material 33, illustrating a configuration in which the shoji screen 10A and the screen door 20 are connected by magnetic force. However, the system is not limited to this configuration. For example, the connecting member may be a convex portion provided on either the shoji screen 10A or the screen door 20 that protrudes in the depth direction, and the connected member may be a concave portion provided on the other of the shoji screen 10A or the screen door 20 that is recessed in the depth direction. Because the connecting member is a convex portion and the connected member is a concave portion, when the operating unit 38 moves from the first position P1 to the second position P2, the convex portion and the concave portion fit together, connecting the shoji screen 10A and the screen door 20 in the depth direction, and allowing the opening and closing of the shoji screen 10A and the opening and closing of the screen door 20 to be linked.

[0043] In this embodiment, a configuration in which switching is performed by sliding both the operating unit 38 and the lock operating unit 45 is illustrated, but the configuration is not limited to this, and for example, a configuration in which switching is performed by a push-button may also be used.
