Description

  The present invention relates to a joinery and an interlocking device, and more particularly to a joinery in which two shojis are opened and closed in conjunction with each other, and an interlocking device used for the joinery.

An interlocking sliding door that has two or more doors (paper shojis) provided adjacent to the frame body in the prospective direction as a fitting used for doorways, etc. It has been known.
In this sliding door, there is a conventional example in which a guide rail is provided on a frame body, the inner door and the outer door are movably guided by the guide rail, and an interlocking roller that contacts the guide rail and the outer door is provided on the inner door. (Patent Document 1).

This patent document 1 is provided with a support means for directly contacting the peripheral surface of the interlocking roller with the inner plate surface of the outer door and the horizontal portion of the guide rail. The supporting means is held by a mounting board provided in the depth direction of the inner door, a movable holder rotatably provided on a pivot provided on the mounting board, and a movable holder so as to be linearly movable in the axial direction. And a biasing spring that biases the roller shaft of the interlocking roller. In Patent Document 1, in order to bring the interlocking roller into contact with the inner plate surface of the outer door and the horizontal portion of the guide rail that are orthogonal to each other, the roller shaft is inclined at an inclination angle of 45 degrees and the tip of the roller shaft is orthogonal. Attached to the intersection of the guide rail and the inner plate surface of the outer door.
In such Patent Document 1, when a gap occurs in the interval between the outer door and the inner door, the interlocking roller urged by the urging spring moves in the axial direction, and the pivot is the center of rotation. The working holder rotates. For this reason, the interlocking roller continues to contact both the guide rail and the outer door.

Japanese Patent No. 4545808

However, in Patent Document 1, if the distance between the outer door and the inner door is shifted due to the deflection of the outer door in the expected direction, the inclination angle of the roller shaft changes. When the inclination angle of the roller shaft changes, the crossing angles of the axial direction to which the urging force of the urging spring is applied and the inner plate surface of the outer door with which the interlocking roller abuts and the abutting surface of the guide rail are different. become. For this reason, the frictional force acting between the interlocking roller and the inner plate surface of the outer door and the frictional force acting between the interlocking roller and the guide rail change, and the interlocking roller does not roll correctly.
Therefore, in patent document 1, when an interlocking roller does not roll correctly, there exists a possibility that an inner door and an outer door may not interlock | cooperate correctly.

  An object of the present invention is to provide a joinery and an interlocking device capable of reliably interlocking a plurality of shojis even when one of the plurality of shojis swings in a prospective direction.

  The joinery of the present invention includes a frame, at least two shojis of a first shoji and a second shoji that are slidably supported by the frame, and the opening and closing movement of the first shoji. An interlocking device that interlocks the second shoji, a prospective surface portion of the summoning portion of the second shoji with the first shoji is formed with a long hole along the prospective direction, An attachment shaft that is rotatably supported by the long hole of the prospective surface portion and is movable in the longitudinal direction of the long hole, a frame to which the attachment shaft is attached, a rotation shaft that is rotatably supported by the frame, and A roller having a rotation axis perpendicular to the axis, a retaining member for preventing the attachment shaft from coming out of the elongated hole, and a biasing member in the direction in which the frame rotates with the attachment shaft as a rotation axis, Different circumferential surfaces along the axis of rotation. In two places, characterized by comprising said abutment surface of the first sliding door, and a biasing member for abutting respectively on the facing surface that faces the contact surface of the frame.

According to the present invention, the roller of the interlocking device attached to the second shoji is opposed to the contact surface of the first shoji and the frame as the first shoji is opened and closed. Interlocked by rotating in contact with the surface.
At this time, the first shoji may swing (move) in the expected direction due to an opening / closing operation or other causes. When the first shoji swings, the dimension between the contact surface of the first shoji that the roller of the interlocking device contacts and the opposing surface of the frame changes.
In the present invention, since the roller is rotated about the mounting shaft by the urging member, the first shoji swings in the prospective direction, and the first shoji between the contact surface of the first shoji and the opposing surface of the frame body Even if the dimensions change, the peripheral surface of the roller abuts against the abutting surface and the opposing surface at two different locations along the axial direction. When the peripheral surface of the roller is in contact with only one of the contact surface and the opposing surface and not the other, the mounting shaft attached to the frame is moved in the longitudinal direction of the long hole by the biasing force of the biasing member. The roller moves along the direction, and the peripheral surface of the roller always comes into contact with the contact surface and the facing surface.
Therefore, even if the first shoji swings, the first shoji and the second shoji are reliably interlocked with each other because the roller abuts against the first shoji and the frame without spinning.
Further, since the attachment shaft of the interlocking device moves in the expected direction in the elongated hole, when the distance between the contact surface of the first shoji and the opposing surface of the frame is changed, the attachment shaft is applied. It can be moved to the center position of the contact surface and the opposing surface. For this reason, each frictional force which acts on a roller, a contact surface, and an opposing surface can also be made the same, and a roller can rotate smoothly and can make a 1st shoji and a 2nd shoji interlock | cooperate reliably.
In addition, since the attachment shaft of the interlocking device moves in the prospective direction in the long hole, even if the first shoji swings in the prospective direction, the second shoji does not move in the prospective direction. For this reason, it does not contact excessively with the guide roller etc. which guide the 2nd shoji, can prevent the increase in force required for opening and closing operation, and can also prevent the opening and closing operability from deteriorating.

  In the joinery of the present invention, the interlocking device is configured such that the peripheral surface of the roller is separated from both the first shoji and the frame body against the urging of the urging member; It is preferable to provide a switching mechanism that allows the biasing member to be biased so that the peripheral surface of the roller is switched to a contact state in which the peripheral surface of the roller contacts the first shoji and the frame.

According to such a configuration, when the roller slips with respect to the first shoji due to sudden opening and closing of the first shoji and the first shoji moves more than necessary with respect to the second shoji. The switching mechanism can easily return the first shoji to the correct position with respect to the second shoji.
That is, in order to return the first shoji to the correct position with respect to the second shoji, the second shoji is stopped and only the first shoji is moved. Since the shoji and the portion of the frame facing the first shoji are biased, secondly, a load is applied to move only the first shoji while the shoji is stationary. In order to eliminate this load, it is necessary to hold the roller with its peripheral surface away from both the first shoji and the frame. It becomes complicated.
Therefore, in the present invention, even if the peripheral surface of the roller is separated from both the first shoji and the frame by the switching mechanism, and the first shoji is operated, the movement of the first shoji I didn't get to the second shoji. Therefore, since it is not necessary for the operator to work while holding the roller, the first shoji can be easily returned to the correct position with respect to the second shoji.
After the first shoji and the second shoji are returned to the correct positions, the roller is switched to the contact state by the switching mechanism. Then, the peripheral surface of the roller comes into contact with both the first shoji and the frame by the urging of the urging member. Therefore, when the first shoji is operated, the movement is transmitted to the second shoji, and the interlocking device operates normally.

In the joinery of the present invention, it is preferable that the switching mechanism includes a hook that is rotatably attached to the prospective surface portion and is locked to the frame.
According to such a configuration, it is possible to easily switch between the separated state and the contact state by rotating the hook. Since the hook can be easily manufactured by processing a plate material, the structure of the switching mechanism can be simplified.

In the joinery of the present invention, the second shoji includes a vertical rod having the prospective surface portion and a finding surface portion orthogonal to the prospective surface portion, and the retaining member is disposed across the prospective surface portion with respect to the frame. The plate has an insertion hole through which the mounting shaft is inserted, the plate is locked to the finding surface portion, and the biasing member is connected to the mounting shaft and one end portion locked to the plate. It is preferable to include a coiled spring member having a second end portion to be locked and a spiral portion that is connected to the one end portion and the other end portion and passes through the attachment shaft.
In such a configuration, the finding surface portion is sandwiched between the plate and the frame, so that the interlocking device can be prevented from being detached from the second shoji. In addition, since the coiled spring member has one end locked to the plate and the other end locked to the mounting shaft, and the mounting shaft is inserted into the spiral portion, the coiled spring member can be installed in a space-saving manner. Can be realized.

The interlock device according to the present invention includes an attachment shaft supported by a hole formed in the attached surface portion, a frame to which the attachment shaft is attached, and a frame that is rotatably supported by the frame and orthogonal to the axis of the attachment shaft. A roller having a rotation axis, a retaining member that prevents the mounting shaft from coming out of the hole of the mounted surface portion, and a bias that biases the frame along the circumferential direction of the mounting shaft against the retaining member. And a biasing member.
Such an interlocking device is attached to the attached surface portion of the second shoji that interlocks with the opening and closing movement of the first shoji. At this time, the urging member can be provided between the retaining member and the mounting shaft, and there is no need to lock the urging member to the attached surface portion. For this reason, it suffices to process only the hole into which the attachment groove is inserted in the attached surface portion to which the interlocking device is attached, and the processing cost of the attached surface portion can be reduced.

  In the present invention, even if one of the plurality of shojis swings in the expected direction, the plurality of shojis can be reliably linked.

  Here, the outdoor surface 11E of the upper collar 11 of the first shoji 10 and the indoor surface 3E of the seamless 3D of the upper frame 3 face each other with the interlocking device 20 in between. Accordingly, the outdoor surface 11E of the upper collar 11 forms a contact surface with which the interlock device 20 contacts the first shoji 10, and the inner surface 3E of the invisible 3D faces the interlock device 20 with which the upper frame 3 contacts. The surface is configured.

A specific configuration of the interlocking device 20 is shown in FIGS. 4 is an exploded perspective view showing a state in which the interlocking device 20 is attached to the vertical rod 14, FIG. 5 is a side view of the interlocking device 20, FIG. 6 is a plan view of the interlocking device 20, and FIG. is there.
As shown in FIG. 4, the interlocking device 20 is attached to the prospective surface portion 341 of the vertical fence (outside summon basket) 34 of the second shoji 30.
The vertical rod 34 is formed of an aluminum extruded shape having a substantially rectangular tube shape, and includes a prospective surface portion 341 and indoor and outdoor finding surface portions 342. And the prospective surface part 341 is a to-be-attached surface part to which the interlock device 20 is attached, and the long hole 343 is formed along the prospective direction (horizontal direction).

  The interlocking device 20 includes a frame 21 disposed along the prospective surface portion 341, a roller 22 rotatably provided on the frame 21, an attachment shaft 23 fixed to the back surface portion of the frame 21, and a retaining member. A plate 24 and a torsion spring 25 as a coiled spring member which is an urging member are provided.

The frame 21 is formed by bending a long metal plate material into a U-shape, and connects a pair of support piece portions 211 that rotatably support the roller 22 and these support piece portions 211. Connecting portion 212 to be connected. For this reason, the support piece part 211 is extended in the direction orthogonal to the connection part 212.
The mounting shaft 23 is attached to the back surface of the connecting portion 212, that is, the back surface of the connecting portion 212 opposite to the surface facing the roller 22. Specifically, the attachment shaft 23 is attached to the center (center of gravity) position of the connecting portion 212.

The roller 22 includes a shaft portion 221 that is rotatably supported by the pair of support piece portions 211, and first and second roller bodies 222 and 223 provided side by side in the axial direction of the shaft portion 221. And have. The roller bodies 222 and 223 are formed of an elastic material such as rubber and are fixed to the shaft portion 221. For this reason, the shaft portion 221 and the roller bodies 222 and 223 rotate integrally with the frame 21.
In addition, the rotation axis 22 </ b> C of the roller 22 is parallel to the longitudinal direction of the connecting portion 212, and thus is orthogonal to the axis 23 </ b> C of the attachment shaft 23.
The roller main bodies 222 and 223 have a maximum diameter smaller than the dimension between the seamless 3D indoor surface 3E of the upper frame 3 and the outdoor surface 11E of the upper collar 11 of the first shoji 10. Designed to be

  The attachment shaft 23 is inserted into the elongated hole 343 of the prospective surface portion 341 of the vertical rod 34 so as to be rotatable and movable in the longitudinal direction (expected direction). In other words, the mounting shaft 23 is inserted into the elongated hole 343 so that the axial center 23C thereof faces in the horizontal direction, and is prevented from being detached by the plate 24 described later. Further, a locking groove 230 for locking the end of the torsion spring 25 is formed on the tip surface of the mounting shaft 23.

The plate 24 is a retaining member that prevents the attachment shaft 23 from coming out of the long hole 343.
The plate 24 is a flat L-shaped plate member, and has a substantially rectangular base portion 241 formed with an insertion hole 240 through which the mounting shaft 23 is inserted, and a contact extending from the one end portion of the base portion 241 in a right angle direction. Part 242. A locking portion 243 that locks the end of the torsion spring 25 is formed on the base portion 241 by cutting and raising.

A torsion spring 25 as a coil spring member (biasing member) is interposed between the mounting shaft 23 and the plate 24.
The torsion spring 25 includes one end 251 locked to the locking portion 243 of the plate 24, the other end 252 locked to the locking groove 230 of the mounting shaft 23, the one end 251 and the other end 252. And a spiral portion 253 wound in a coiled shape. The spiral portion 253 is inserted through the mounting shaft 23.
The torsion spring 25 applies a biasing force that relatively rotates the mounting shaft 23 and the plate 24 in directions opposite to each other. As a result, when the abutting portion 242 of the plate 24 abuts on the finding surface portion 342 of the vertical rod 34 and the plate 24 is prevented from rotating, the mounting shaft 23 rotates clockwise in FIG.
When the mounting shaft 23 rotates clockwise in FIG. 1, the upper roller body 222 contacts the outdoor surface 11E of the upper arm 11 of the first shoji 10, and the lower roller body 223 is seamless 3D. It contacts the interior surface 3E. In the plate 24 illustrated in FIG. 7, the solid line is in a state before being mounted inside the vertical rod 34 (before the torsion spring 25 is bent), and the imaginary line is mounted inside the vertical rod 34. The rear state (after the torsion spring 25 is bent) is shown. In a state where the plate 24 is mounted inside the vertical rod 34, the torsion spring 25 bends as much as the plate 24 is rotated 90 degrees. Therefore, when the plate 24 is used as a reference, the torsion spring 25 causes the plate 24 to move in the circumferential direction of the mounting shaft 23 so that the mounting shaft 23 and the frame 21 rotate counterclockwise in FIG. Energize along.

  In the interlock device production factory, the interlocking device 20 fixes the mounting shaft 23 to the connecting portion 212 of the frame 21, and the roller 22 is rotatably attached to the support piece portion 211 to form a unit. Then, the unitized frame 21, roller 22, and mounting shaft 23 are shipped together with the plate 24 and the torsion spring 25. At this time, the plate 24 may be inserted into the attachment shaft 23 and the torsion spring 25 may be shipped with the attachment shaft 23 and the plate 24 attached, or the plate 24 and the torsion spring 25 may be shipped without attachment. .

The interlocking device 20 is attached to the joinery 1 at a production factory for the joinery 1 or at a construction site.
In order to attach the interlocking device 20 to the prospective surface portion 341 which is the attached surface portion of the joinery 1, as shown in FIG. 4, the attachment shaft 23 of the interlocking device 20 is connected to the prospective surface portion 341 of the vertical rod 34 of the second shoji 30. Is inserted into the long hole 343. Further, the plate 24 is inserted from the open end face of the vertical rod 34, and the plate 24 is attached to the mounting shaft 23. Further, a torsion spring 25 is interposed between the plate 24 and the mounting shaft 23. When the torsion spring 25 is interposed between the plate 24 and the mounting shaft 23, a biasing force in the circumferential direction of the mounting shaft 23 is applied to the plate 24 and the frame 21. In this state, the frame 21 is rotated in the circumferential direction around the mounting shaft 23 by the urging of the torsion spring 25, and the roller body 222 of the roller 22 comes into contact with the outdoor surface 11 E of the upper saddle 11 of the first shoji 10. The roller body 223 comes into contact with the 3D indoor surface 3E of the upper frame 3.

  In the fitting 1 in which the interlock device 20 is provided in the second shoji 30, when the first shoji 10 is opened and closed, the roller body 222 rolls along the upper arm 11 of the first shoji 10, and this rolling The lower roller body 223 to which is transmitted rolls along the invisible 3D indoor surface 3E of the upper frame 3 so that the second shoji 30 opens and closes at half the speed of the first shoji 10.

Here, as shown in FIG. 8, the first shoji 10 may swing in the expected direction due to wind pressure or a force applied during the opening / closing operation. When the first shoji 10 swings, the dimension between the outdoor surface 11E of the upper collar 11 of the first shoji 10 and the indoor surface 3E of the seamless 3D of the upper frame 3 increases, but the torsion spring 25 is attached. Due to the force, the roller 22 continues to be urged in the circumferential direction P1 about the mounting shaft 23, the roller body 222 located above contacts the outdoor surface 11E, and the roller body 223 contacts the indoor surface 3E. Maintain the state.
If only one of the upper and lower roller bodies 222, 223 is in contact with the first shoji 10 or the invisible 3D, but the other is not in contact with the first shoji 10 or the invisible 3D, By the biasing of the torsion spring 25, the mounting shaft 23 is displaced in the prospective direction P2 along the long hole 343, so that the roller body 222 is surely brought into contact with the first shoji 10 and the roller body 223 is seamless 3D. Abuts securely. In FIG. 8, the circumferential direction P1 of the mounting shaft 23 around which the roller 22 rotates is clockwise. However, by changing the urging direction of the torsion spring 25, the counterclockwise direction is set, and the roller body 222 is seamless 3D. The roller body 223 can be brought into contact with the first shoji 10.

According to this embodiment, there are the following effects.
(1) A long hole 343 is formed in the finding surface portion 342 of the vertical rod 34, the mounting shaft 23 is inserted into the long hole 343, the mounting shaft 23 is prevented from being detached by the plate 24, and the mounting shaft is secured by the torsion spring 25. Since the frame 21 is urged in the direction of rotation about the axis 23, the roller body even if the first shoji 10 is swung in the expected direction and the dimension between the first shoji 10 and the invisible 3D changes. 222 can be brought into contact with the first shoji 10 and the roller body 223 can be brought into contact with the invisible 3D. Accordingly, the roller main bodies 222 and 223 can always be brought into contact with the first shoji 10 and the invisible 3D, and even if the first shoji 10 is swung in the expected direction, the roller 22 does not run idle. Therefore, the first shoji 10 and the second shoji 30 can be reliably interlocked with each other.

(2) Moreover, since the attachment shaft 23 can move in the prospective direction along the longitudinal direction of the long hole 343, the attachment shaft 23 is moved to the center of the outdoor surface 11E of the first shoji 10 and the indoor surface 3E of the seamless 3D. Can be placed in position. Therefore, the frictional forces acting on the roller bodies 222 and 223 and the outdoor surface 11E and the indoor surface 3E can be made the same, and the roller 22 rotates smoothly so that the first shoji 10 and the second shoji 30 are surely and smoothly. Can be opened and closed in conjunction with.

(3) In addition, since the mounting shaft 23 of the interlocking device 20 moves in the expected direction in the elongated hole 343, even if the first shoji 10 swings in the expected direction, the second shoji 30 moves in the expected direction. There is nothing. For this reason, the guide portion 32A does not excessively contact the guide roller 5B that guides the second shoji 30, and an increase in force required for the opening / closing operation can be prevented, and a decrease in opening / closing operability can also be prevented.

(4) Since the torsion spring 25 is interposed between the mounting shaft 23 and the plate 24, it is not necessary to cut and raise the end of the torsion spring 25 to engage the vertical rod 34. For this reason, it suffices to process only the elongated hole 343 in the vertical bar 34, and the manufacturing cost of the joinery 1 can be suppressed.

(5) One end 251 of the torsion spring 25 is locked to the locking portion 243 of the plate 24, the other end 252 is locked to the locking groove 230 of the mounting shaft 23, and the spiral portion 253 is fixed to the mounting shaft 23. Since it is the structure inserted, the structure of a biasing member can be simplified and arrangement space can also be made small.

(6) The plate 24 is composed of an L-shaped plate member having a base portion 241 and a contact portion 242, and the plate 24 is prevented from rotating by contacting the contact portion 242 with the finding surface portion 342 of the vertical rod 34. Is going. For this reason, even if the plate 24 and the mounting shaft 23 move in the prospective direction along the long hole 343, the contact angle of the contact portion 242 with the finding surface portion 342 changes somewhat, but the contact state, that is, the rotation preventing state Therefore, the rotation prevention of the plate 24 can be realized with a simple configuration.

[Second Embodiment]
Next, a fitting 1A according to a second embodiment of the present invention will be described with reference to FIG.
FIG. 9 is an enlarged cross-sectional view showing the upper part of the joinery 1A. In FIG. 9, the first shoji 10 shows only the upper arm 11.
The interlocking device 20A of the second embodiment is different from the interlocking device 20 of the first embodiment in that a switching mechanism 26 is provided. Since the other configuration is substantially the same as that of the first embodiment, the switching mechanism 26 will be described.

The switching mechanism 26 includes a hook 26 </ b> A disposed below the frame 21, and a screw portion 26 </ b> B that rotatably attaches the hook 26 </ b> A to the prospective surface portion 341.
The hook 26 </ b> A is a metal fitting whose one end is rotatably attached to the prospective surface portion 341 of the second shoji 30 by the screw portion 26 </ b> B and whose other end can be locked to the support piece portion 211 of the frame 21.
And the axial part 221 of the roller 22 can be orient | assigned to a perpendicular direction by latching the support piece part 211 of the flame | frame 21 with the other end of hook 26A. For this reason, the peripheral surface of the roller 22 resists the urging force of the torsion spring 25 and becomes a separated state (position indicated by a solid line) separated from both the first shoji 10 and the invisible 3D.
On the other hand, when the hook 26A is removed from the support piece portion 211, the urging force of the torsion spring 25 is allowed, and the circumferential surface of the roller 22 is in contact with the first shoji 10 and the invisible 3D (in phantom lines). Position).

In the second embodiment, the same effects as in the first embodiment can be obtained, and the following effects can be obtained.
(7) The interlocking device 20A has a separated state in which the circumferential surface of the roller 22 is separated from both the first shoji 10 and the invisible 3D against the bias of the torsion spring 25, and the bias of the torsion spring 25 And a switching mechanism 26 for switching between the contact state in which the peripheral surface of the roller 22 contacts the first shoji 10 and the invisible 3D.
For this reason, even if the roller 22 slips with respect to the first shoji 10 due to a sudden opening and closing of the first shoji 10 and the first shoji 10 moves more than necessary with respect to the second shoji 30, The switching mechanism 26 can easily return the first shoji 10 to the correct position with respect to the second shoji 30.
In particular, if the hook 26A is locked to the support piece 211 of the frame 21, the operator does not need to move the first shoji 10 while holding the frame 21 by hand. Workability at the time can be improved.

(8) Since the switching mechanism 26 includes a hook 26A having one end pivotably attached to the prospective surface portion 341 and the other end locked to the support piece portion 211 of the frame 21, only the hook 26A is rotated. Thus, the switching operation can be easily performed.

Note that the present invention is not limited to the above-described embodiments, and includes other configurations that can achieve the object of the present invention, and includes the following modifications and the like.
For example, in each of the above embodiments, the roller 22 has a structure in which the two roller main bodies 222 and 223 are mounted side by side in the axial direction of the shaft portion 221. However, in the present invention, the roller 22 is configured by a single cylindrical member. You may do. However, if the two roller main bodies 222 and 223 are arranged side by side on the shaft portion 221 as in the above embodiments, the volume of the entire roller can be reduced, so that the amount of elastic material used for the roller 22 is reduced. can do. By reducing the elastic material, the manufacturing cost of the roller 22 can be reduced and the weight can be reduced, so that the roller 22 can be rotated smoothly.

In each of the above embodiments, the urging member is the torsion spring 25. However, the urging member of the present invention is not limited to the torsion spring. For example, the engagement protrusion provided on the plate 24 and the mounting shaft 23 are provided. It is good also as elastic members, such as rubber | gum interposed between the protrusions for latching provided in the surrounding surface. Further, as the urging member, a spring other than the torsion spring 25 may be used.
Further, in the above embodiment, the one end 251 of the torsion spring 25 is locked to the plate 24, but the one end 251 of the torsion spring 25 is engaged with the inside of the vertical rod 34 of the second shoji 30. It is good also as a structure.

  Furthermore, the position where the roller 22 rolls in the first shoji 10 is not limited to the position where it contacts the outdoor surface 11E of the upper collar 11 and the indoor surface 3E of the seamless 3D. For example, when the lower frame having a rail for guiding the respective shojis 10 and 30 is provided on the joinery frame 2, the interlocking device 20 may be disposed at a position where the lower frame 12 and the lower frame abut.

  The switching mechanism 26 is not limited to the configuration of the second embodiment. That is, the switching mechanism 26 allows the separated state in which the circumferential surface of the roller 22 is separated from both the first shoji and the invisible 3D against the bias of the torsion spring 25 and the bias of the torsion spring 25. As long as the peripheral surface of the roller 22 is switched to the contact state in which the first shoji 10 and the invisible 3D are in contact with each other, the specific configuration is not questioned. For example, the switching mechanism includes a slider member that can be advanced and retracted to a forward position where the support piece portion 211 of the frame 21 is locked and a retracted position separated from the support piece portion 211, and the slider member is locked to the forward position or the retracted position. The structure which has the latching member to perform may be sufficient.

Moreover, in the said embodiment, although the maximum diameter dimension of the roller 22 was set smaller than the dimension between the indoor surface 3E of the seamless 3D of the upper frame 3, and the outdoor surface 11E of the upper collar 11 of the 1st shoji 10. When the switching mechanism 26 is not used, the maximum diameter dimension of the roller 22 may be the same as the dimension between the inner surface 3E of the seamless 3D and the outer surface 11E of the upper collar 11.
In this case, when the switching mechanism 26 is not used, the peripheral surfaces of the two roller bodies 222 and 223 are in contact with both the invisible 3D and the upper collar 11, and the shaft portion 221 extends vertically. Become.
On the other hand, when the first shoji 10 is swung in the prospective direction and the distance between the two is widened, the shaft portion 221 is inclined and one of the two roller bodies 222 and 223 hits the upper arm 11 of the first shoji 10. The other is in contact with the invisible 3D.

In addition, the joinery of the present invention is not limited to the windbreak room joinery of each of the embodiments described above, and the entrance joinery other than the windbreak room, the bathroom entrance joinery, and further, the room, storage, warehouse, etc. You may use the fitting of this invention for an entrance / exit or a window.
Further, a wall body (planar body) or a door pocket may be provided in place of the fixture of the present invention and the fixed shoji (third shoji 40) of the above-described embodiment, and substantially overlaps with the wall body and two sheets. A configuration in which the shoji is opened or a configuration in which the two shojis are housed in the door pocket and opened is possible.
