Description

  The present invention relates to a joinery that regulates deformation of a shoji screen due to heat.

  Provided with a sliding door sliding door inside the sash frame, for example, a sliding door sliding door with a door lock, and with the sliding door closed, the sliding door is locked to the sash frame with the door locking. A sash is known (see, for example, Patent Document 1). Such a sash shoji is excellent in design because, for example, the shoji with a crescent lock does not protrude outward from the summit serving as the door butt.

JP 2011-42935 A

  However, the shoji, which is locked to the sash frame by the door lock, was heated by a fire, etc. At this time, when the cocoon is deformed so as to expand due to heat and the reed extends, each summoning sword moves in the direction of finding, or the summoning cocoon warps. For this reason, there exists a subject that a clearance gap may arise in the door bottom part of the shoji which makes the summoning part of a sliding shoji.

  This invention is made | formed in view of this subject, The place made into the objective provides the fitting which controls the deformation | transformation of a shoji so that a clearance gap may not arise in the site | part on the door butt side of a shoji even if it heats. There is.

  In order to achieve this object, the joinery of the present invention is a joinery having a frame and a shoji that moves so as to be openable and closable with respect to the frame, and when the shoji is closed, the door bottom of the shoji Any one of the first part and the opposite part facing the Tojiri heel in the prospective direction is set as one side part, the other is set as the other side part, and the first member is provided on the one side part. A second member is provided on the side, and the first member is movable relative to the second member as the shoji is opened and closed, and the shoji is heated with the shoji closed. Accordingly, when the first member is deformed and engaged with the second member, the relative movement is restricted.

  According to such a fitting, the first member provided on one side in a state in which the shoji is closed is deformed so as to extend when the shoji is heated and is engaged with the second member, Since the relative movement is restricted, even if the shoji is heated by a fire or the like, there is no significant deviation between the door bottom and the facing portion of the shoji. For this reason, it is possible to prevent a gap from being generated between the door bottom portion and the facing portion.

  Further, since the first member is deformed by being heated and can be engaged with the second member, the first member is not deformed if not heated, and the second member is connected to the first member as the shoji slides. Relative movement is possible. For this reason, when the shoji is not heated, it is possible to slide the shoji so that it can be opened and closed.

  In this joinery, in the state in which the shoji is closed, the first member is spaced apart from the one-side finding surface, and the one-side finding surface from the spacing portion. And the second member has a protruding portion that protrudes toward the one side portion and is disposed in the spaced-apart portion, and the extending portion is It is located on the other side of the projecting part in the prospective direction, and when the shoji is heated, it is arranged at a position facing the second member in the finding direction so as to regulate the relative movement. Preferably, the first member is deformed.

  According to such a joinery, the extending portion of the first member is disposed at a position facing the second member in the direction of finding so as to restrict relative movement when the shoji is heated, so that the shoji is Even if it is deformed so that it is heated and stretched, the extension part contacts the second member, and further deformation in the direction in which the shoji is found is restricted. For this reason, it is possible to suppress a deformation | transformation of a shoji and to prevent a clearance gap between a door bottom part and a facing part of a shoji.

  In this joinery, the first member is an elastically deformable metal member having one end fixed to the one side and the other end provided with the extension, and the one side and the first A gap forming member having a lower melting point than that of the first member is interposed between the extension portion and the extension portion, and the second member is elastically deformed. It is desirable that the gap forming member is melted by heating the shoji and is deformed so that the elastic deformation of the first member is restored.

  According to such a joinery, the first member having one end fixed to one side is elastically deformed with the gap forming member interposed between the extending portion provided on the other end and the one side. Therefore, it is possible to arrange the extension part at a distance from the one side part. Moreover, since the gap forming member has a lower melting point than the door bottom, the facing portion, and the first member, when the shoji is heated, it is melted and the extending portion moves to one side. Thereby, even if it is a case where a shoji is heated and deform | transforms so that it may expand | extend, an extension part and the 2nd member will engage, and the further deformation | transformation to the finding direction of a shoji will be controlled. For this reason, it is possible to suppress a deformation | transformation of a shoji and to prevent a clearance gap between a door bottom part and a facing part of a shoji.

  In this joinery, the first member is an elastically deformable metal member having one end fixed to the one side and the other end provided with the extension, and the one side and the first A heating foam material is interposed between the extending portion and elastically deformed, the second member is disposed between the first member and the one side portion, and the shoji is heated. By doing so, the heated foam material may be foamed and deformed to restore elastic deformation of the first member.

  According to such a joinery, the first member having one end fixed to one side is elastically deformed with the heating foam interposed between the extending portion provided on the other end and the one side. Therefore, it is possible to arrange the extension part at a distance from the one side part. Further, when the shoji is heated, the heated foaming material foams and the density becomes low and becomes brittle. Therefore, the extension portion moves to one side due to the elasticity of the first member. Thereby, even if it is a case where a shoji is heated and deform | transforms so that it may expand | extend, an extension part and a 2nd member will engage, and the deformation | transformation to the finding direction of a shoji will be controlled. For this reason, it is possible to suppress a deformation | transformation of a shoji and to prevent a clearance gap between a door bottom part and a facing part of a shoji.

  In this joinery, the first member is a metal laminated member in which one end is fixed to the one side, the extension is provided at the other end, and two kinds of metals having different linear expansion coefficients are laminated. Of the two types of metals, the metal with the smaller linear expansion coefficient is on the one side, and the metal with the larger linear expansion coefficient of the two types of metals is on the one side. It is arranged on the opposite side, the second member is arranged between the first member and the one side part, and the metal laminated member has the linear expansion coefficient when the shoji is heated. It is good also as changing by difference.

  According to such a joinery, in the first member having one end fixed to one side, the extending portion provided on the other end is disposed with a distance from the one side. In addition, the first member has a metal linear member having a smaller linear expansion coefficient disposed on one side and a metal having a larger linear expansion coefficient disposed on the opposite side to the one side. When the metal is heated, the metal having the larger linear expansion coefficient is bent by extending from the metal having the smaller linear expansion coefficient, and the extension part moves to one side. Thereby, even if it is a case where a shoji is heated and deform | transforms so that it may expand | extend, an extension part and a 2nd member will engage, and the deformation | transformation to the finding direction of a shoji will be controlled. For this reason, it is possible to suppress a deformation | transformation of a shoji and to prevent a clearance gap between a door bottom part and a facing part of a shoji.

  In this joinery, the second end of the door butt portion and the facing portion is provided with a second piece in which the tips of the first pieces respectively projecting in directions facing each other extend in opposite directions in the finding direction. Each of the second pieces provided in the facing portion is located on the opposite side of the facing portion with respect to the second piece provided in the door butt portion when the shoji is closed. The second piece of the first member is disposed in such a manner that the second pieces of the second piece overlap in the prospective direction, and when the shoji is heated, the first member is in a state where the second pieces overlap in the prospective direction. It is desirable to engage with the second member.

  According to such a joinery, when the shoji is heated, the first member locks the second member in a state where each second piece constituting the smoke return overlaps in the prospective direction. For this reason, even if it is a case where a shoji is heated and deform | transforms so that it may extend, the state where each 2nd piece of smoke return has overlapped in the prospective direction is maintained. Therefore, even if the shoji is heated, it is possible to more surely prevent a gap from being generated at the door butt side of the shoji.

  ADVANTAGE OF THE INVENTION According to this invention, it is possible to provide the fitting which regulates a deformation | transformation of a shoji so that a clearance gap may not arise in the site | part on the door butt side of a shoji even if it heats.

The second inner piece 38b and the second outer piece 48b are arranged so as to overlap in the prospective direction.

  In addition, a sealing material 12 made of a soft synthetic resin is provided on the Tojiri side 48 of the shoji 4 from the second outer piece 48 b to the Tojiri side over almost the entire length of the Tojiri 48 in the longitudinal direction. It is provided so as to come into contact with the Tojiri ridge 38.

  As shown in FIG. 3 and FIG. 4, the deformation regulating structure of the shoji in the present fitting 1 includes the first inner piece 38 a and the second inner piece 38 b of the Tojiri heel 38 of the inner shoji 3 and the Tojiri heel of the outer shoji 4. The first outer piece 48a and the second outer piece 48b of 48 are partly cut away. In addition, the surface of the Tojiri heel 38 of the inner shoji 3 that faces the Tojiri heel 48 of the shoji 4 and the restriction member 20 is fixed is heated along the Tojiri heel 38 above and below the restriction member 20. A foam material 30 is provided. Further, the surface of the Tojiri 48 of the outer shoji 4 facing the Tojiri 38 of the inner shoji 3 and the pin 21 is provided on the side opposite to the second outer piece 48b in the direction in which the Tojiri 48 is located. The heated foam material 30 is provided along the Tojiri ridge 48. In addition, in the figure, although the example which provided the heating foam material 30 divided | segmented up and down in the position where the control member 20 and the pin 21 are provided is shown, if the control member 20 and the pin 21 are avoided, It may be provided so as to extend over the entire length of the Tojiri ridges 38 and 48 of the inner shoji 3 and the outer shoji 4, or may be provided so as to connect the upper and lower heating foam materials 30.

  The deformation restricting structure of the shoji according to the present embodiment includes a restricting member 20 as a first member disposed at a site where the first inner piece 38a and the second inner piece 38b of the Tojiri heel 38 of the inner shoji 3 are cut off, The pin 21 as the metal second member arranged at the site where the first outer piece 48a and the second outer piece 48b of the Tojiri 48 of the shoji 4 are excised, the regulating member 20 and the Tojiri of the inner shoji 3 38, and a gap forming member 22 interposed therebetween.

  The restricting member 20 is formed of a metal leaf spring that can be elastically deformed. The two wall portions 20a and 20b are substantially orthogonal to each other, and the horizontal cross section is substantially L-shaped. One of the two L-shaped wall portions 20a, 20b is a fixed wall portion 20a, one end of which is fixed to the door butt heel 38 of the inner shoji 3, and the other end of the fixed wall portion 20a is L-shaped. This is a restriction wall portion 20 b as an extending portion that is formed by bending the pin 21 and engages with the pin 21.

  The fixed wall portion 20a is brought into contact with the door butt side from the first inner piece 38a that is cut off at the one end side of the door butt heel 38, which faces the door butt ridge 48 of the external shoji 4, and the other end side is cut out. It arrange | positions so that it may protrude to the door end side from 1 inner piece 38a, and is screwed to the reinforcement member 10 provided in the hollow part 8a. Further, on the other end side of the fixed wall portion 20a, a U-shaped cutout portion 20c is provided at the center in the up-down direction and is cut out along the finding direction, connected to the restriction wall portion 20b. For this reason, the regulation wall part 20b is divided into two upper and lower sides across the notch part 20c.

  Since the Tojiri heel 38 of the inner shoji 3 is partly cut away from the first inner piece 38a and the second inner piece 38b, the door tip side in the direction of finding is closer to the first inner piece 38a than the first inner piece 38a. In the prospective direction, it is depressed on the side opposite to the external shoji 4. For this reason, when the regulating member 20 having the regulating wall portion 20b bent from the fixed wall portion 20a of the regulating member 20 is simply screwed to the door bottom side of the first inner piece 38a, as shown in FIG. The restriction wall 20b is disposed in the recess, and the fixed wall 20a of the restriction member 20 becomes flat. At this time, the fixed wall portion 20a disposed with the gap S between the Tojiri ridges 38 corresponds to the separation portion.

  As shown in FIG. 6, the regulating member 20 of the present embodiment is provided with a gap forming member 22 between the regulating wall portion 20 b and the Tojiri heel 38 of the inner cot 3, and the thickness of the interposed gap forming member 22. It is elastically deformed. The gap forming member 22 is a block made of, for example, a synthetic resin whose melting temperature is lower than that of the door bottom ridges 38 and 48, the regulating member 20, and the pin 21. The gap forming member 22 is interposed between the upper restriction wall portion 20b and the lower restriction wall portion 20b and the door bottom ridge 38 with the notch 20c interposed therebetween.

  The vertical length of the gap forming member 22 is shorter than the vertical lengths of the upper restriction wall portion 20b and the lower restriction wall portion 20b. The gap forming member 22 interposed between the upper restriction wall portion 20b and the door bottom ridge 38 is positioned above the lower end of the upper restriction wall portion 20b, that is, the upper edge of the notch portion 20c. The gap forming member 22 that is disposed and interposed between the lower regulating wall portion 20b and the door bottom ridge 38 is positioned below the upper end of the lower regulating wall portion 20b, that is, the lower edge of the notch portion 20c. It arrange | positions so that it may adhere and is adhere | attached on the Tojiri ridge 38. For this reason, the distance L1 between the lower end of the upper gap forming member 22 and the upper end of the lower gap forming member 22 is set wider than the vertical width L2 of the notch 20c.

  Further, as shown in FIG. 7, the width W1 in the direction of finding the gap forming member 22 is the width W2 in the direction of finding the regulating wall 20b of the regulating member 20, that is, the thickness of the plate material forming the regulating member 20. Widely formed. The gap forming member 22 is biased from the regulating wall portion 20b toward the door tip side of the inner impeller 3 so that the restricting wall portion 20b is brought into contact with the gap forming member 22 in the vicinity of the edge portion on the door butt side of the inner impeller 3. Are arranged.

  As shown in FIG. 6, the pin 21 enters the notch 20 c provided in the restricting member 20 in a state in which the inner and outer children 3 and 4 are closed, and when the inner and outer children 3 and 4 are opened and closed. The restriction member 20 is provided so as to be relatively movable along the notch 20c.

  One end of the pin 21 is formed with a threaded portion 21a for fixing to the fixing bracket 14 (FIG. 7) fixed to the reinforcing member 10 provided in the hollow portion 8a of the Tojiri 48 of the external shoji 4. The thin shaft portion 21b connected to the screw portion 21a and the thick shaft portion 21c as a protruding portion on the other end side connected to the thin shaft portion 21b.

  The diameter D1 of the thin shaft portion 21b is formed smaller than the vertical width of the cutout portion 20c, and the diameter D2 of the thick shaft portion 21c is larger than the vertical width L2 of the cutout portion 20c and the upper gap It is formed smaller than the distance L1 between the lower end of the forming member 22 and the upper end of the lower gap forming member 22.

  The pin 21 has a screw portion 21a screwed to the fixing bracket 14 and is fixed, and the thick shaft portion 21c is positioned at the tip of the restriction wall portion 20b in which the gap forming member 22 is interposed between the door butt collar 38 and the pin 21. It is formed so as to be located closer to the door bottom. The expected thickness t1 of the thick shaft portion 21c is the distance between the front end of the regulating wall portion 20b with the gap forming member 22 interposed therebetween and the surface of the Tojiri ridge 38 to which the gap forming member 22 is bonded, that is, The gap forming member 22 is formed thinner than the thickness t2.

  For this reason, in the state where the gap forming member 22 is interposed between the restricting member 20 and the Tojiri heel 38 of the inner impeller 3, the pin 21 and the restricting member 20 do not engage with each other. As shown in FIG.8 (c), the inner impingement child 3 and the outer imperial child 4 can open and close the opening 2a by sliding to a finding direction.

  In a state in which the inner shoji 3 and the outer shoji 4 are closed, that is, in a state in which the door rod 7 of the inner shoji 3 and the outer shoji 4 is locked to the frame 2 and the shoji is closed, the thin shaft portion 21b of the pin 21 is The notch 20c of the restricting member 20 enters the thick shaft portion 21c, and the thick shaft portion 21c is positioned on the side of the inner child 3 from the fixed wall portion 20a of the restricting member 20.

  When the inner shoji 3 and the outer shoji 4 are heated by a fire or the like with the shoji closed, in the summoning section, the gap forming member whose melting temperature is lower than that of the Tojiri mushrooms 38 and 48, the regulating member 20 and the pin 21 22 begins to melt. At this time, since the regulation wall portion 20b is in contact with the vicinity of the edge portion of the gap forming member 22, it starts to melt faster. Further, at this time, the regulating member 20 elastically deformed by the interposition of the gap forming member 22 presses the gap forming member 22 melted and softened by the elastic force restored by the regulating member 20, and FIG. As shown to (d), it deform | transforms so that the fixed wall part 20a of the control member 20 may become flat. That is, the restricting member 20 is deformed so that the restricting wall portion 20b is disposed at a position facing the pin 21 in the finding direction so as to restrict the relative movement of the pin 21, and is in a state where it can be engaged with the pin 21. .

  When the restricting member 20 is deformed, the inner shoji 3 or the outer shoji 4, or the inner shoji 3 and the outer shoji 4 are heated together, so that the upper arm, lower arm 6, door toe 7, and The Tojiri ridge 8 is deformed to extend. In particular, the inner shoji 3 and the outer shoji 4 to which the door toe 7 is locked are moved in a direction in which the door butt toe 38 and 48 are separated from the door toe when the upper and lower eyelids 6 are extended. However, when the upper heel and the lower heel 6 extend and the Tojiri heels 38 and 48 move, the pin 21 provided on the Tojiri heel 48 of the external shoji 4 engages with the restriction wall portion 20b of the restriction member 20. By being regulated together, the Tojiri rods 38 and 48 cannot move, and further deformation of the upper and lower rods 6 is regulated.

  At this time, even if the gap forming member 22 does not melt and does not exist at all, the gap forming member 22 is melted to such a degree that the regulating wall portion 20b of the regulating member 20 moves to a position where it can engage with the thick shaft portion 21c of the pin 21. It does not matter if it is made.

  Further, in a state in which the restriction wall portion 20 b of the restriction member 20 can be engaged with the thick shaft portion 21 c of the pin 21, the thick shaft portion 21 c of the pin 21 is positioned closer to the inner pouch 3 than the fixed wall portion 20 a of the restriction member 20. Therefore, the movement of the door butt 48 of the external shoji 4 provided with the pin 21 to the outdoor side is also restricted.

  According to the deformation restricting structure of the shoji according to the present embodiment, the restricting member 20 provided on the Tojiri heel 38 of the inner shoji 3 with the shoji closed is obtained by heating the inner shoji 3 and the outer shoji 4. Since it deform | transforms so that it may extend | expand and it engages with the pin 21 and the deformation | transformation of the subsequent inner impeller 3 and the outer imperial child 4 is controlled, even if the inner imperial child 3 and the outer imperial child 4 are heated by a fire etc., an inner 3 is not greatly displaced between the Tojiri sash 38 and the Tojiri sash 48 of the shoji 4 so that a gap can be prevented.

  In addition, the regulating member 20 having one end fixed to the Tojiri heel 38 of the inner shoji 3 includes a regulating wall portion 20b provided at the other end and the Tojiri heel 38 of the inner shoji 3 on which the regulating member 20 is provided. Since the gap forming member 22 is interposed therebetween and elastically deformed, the restriction wall portion 20b may be arranged at a distance from the door butt heel 38 of the inner shoji 3 where the restriction member 20 is provided. Is possible.

  Since the regulating member 20 is deformed by being heated and melted when the inner shroud 3 and the outer shoji 4 are heated, the regulating member 20 can be engaged with the pin 21, so that the gap forming member 22 is heated. Otherwise, the pin 21 is not deformed, and the pin 21 can be moved relative to the restricting member 20 as the inner and outer obstacles 3 and 4 slide. For this reason, when the inner shoji 3 and the outer shoji 4 are not heated, the inner shoji 3 and the outer shoji 4 can be slidably opened and closed.

  At this time, the gap forming member 22 has a lower melting point than the Tojiri ridges 38 and 48 of the inner and outer children 3 and 4 and the regulating member 20, and therefore melts when the inner and outer children 3 and 4 are heated. Then, the regulation wall 20b moves to the Tojiri side where the regulation member 20 is provided. That is, the restriction wall portion 20b of the restriction member 20 is arranged at a position facing the pin 21 in the direction of finding so as to restrict the relative movement of the pin 21 by heating the inner and outer obstacles 3 and 4. Thereby, even if it is a case where it deform | transforms so that the inner shoji 3 and the outer shoji 4 may be heated and extended, the regulation wall part 20b and the pin 21 will engage, and the finding direction of the inner shoji 3 and the outer shoji 4 Extension to is regulated. For this reason, it is possible to suppress the deformation of the inner shoji 3 and the outer shoji 4 and prevent a gap from occurring in the summing portion of the inner shoji 3 and the outer shoji 4.

  Further, in a state in which the restriction wall portion 20 b of the restriction member 20 can be engaged with the thick shaft portion 21 c of the pin 21, the thick shaft portion 21 c of the pin 21 is positioned closer to the inner pouch 3 than the fixed wall portion 20 a of the restriction member 20. Therefore, the movement of the door shoji 48 to the outdoor side of the shoji 4 is also restricted. For this reason, the inner shoji 3 and the outer shoji 4 are heated, and each Tojiri 38,48 warps, or the lower side of the frame 2 on which the outer shoji 4 is placed is heated and softened. Even if it begins to fall, it is possible to prevent a gap from occurring in the summing portion of the inner shoji 3 and the outer shoji 4.

  In the state where the shoji is closed, the second inner piece 38b of the Tojiri heel 38 of the inner shoji 3 forming the smoke return 13 and the second outer piece 48b of the outer shoji 4 overlap in the prospective direction. For this reason, even if the inner shoji 3 and the outer shoji 4 are heated, when the restriction member 20 and the pin 21 are engaged and the deformation of the inner shoji 3 and the outer shoji 4 is restricted, the smoke return 13 The state where the second inner piece 38b and the second outer piece 48b overlap in the prospective direction is maintained. For this reason, even if the inner shoji 3 and the outer shoji 4 are heated, it is possible to more reliably prevent a gap from being generated between the door butt ridges 38, 48 of the inner shoji 3 and the outer shoji 4.

  In the above embodiment, the gap forming member 22 is a synthetic resin block whose melting temperature is lower than that of the Tojiri ridges 38 and 48, the regulating member 20, and the pin 21, but is not limited thereto. For example, it may be a heating foam material such as thermally expandable graphite which is heated and foamed, similar to the heating foam material 30 provided on the Tojiri heel 38 of the inner shoji 3 and the Tojiri heel 48 of the outer shoji 4. . In this case, when heated and foamed, the foamed portion of the heated foam material has a low density and becomes brittle. At this time, the heating foam material is crushed by the regulating wall portion 20b by the elastic force of the regulating member 20 that is elastically deformed with the heating foam material interposed therebetween, so that the regulating wall portion 20b of the regulating member 20 becomes the door bottom wall 38. Move to the side. Thereby, even if it is a case where the inner shoji 3 and the outer shoji 4 are deform | transformed so that it may be heated and expand | extended, a control wall part and the pin 21 will engage, and it will go to the direction of finding the inner shoji 3 and the outer shoji 4 The deformation of is regulated. For this reason, it is possible to suppress the deformation of the inner shoji 3 and the outer shoji 4 and prevent a gap from occurring in the summing portion of the inner shoji 3 and the outer shoji 4.

  Moreover, in the said embodiment, when the inner shoji 3 and the outer shoji 4 were heated in the state which closed the shoji, the clearance gap formation member 22 melted or foamed and was elastically deformed by the clearance gap formation member 22. The example in which the elastic deformation of the restricting member 20 is deformed so as to be restored and can be engaged with the pin 21 has been described, but is not limited thereto. For example, the restricting member is a metal laminated member in which two types of metals having different linear expansion coefficients are laminated, and the metal having the smaller linear expansion coefficient is the Tojiri heel of the inner cot 3 in which the restricting member is provided. The metal having the larger linear expansion coefficient may be formed on the 38 side so as to be arranged on the Tojiri side 48 side of the shoji 4. In this case, when the inner and outer children 3 and 4 are heated, the metal having the larger linear expansion coefficient is expanded from the metal having the smaller linear expansion coefficient, thereby forming two kinds of metals. The restricting member is bent, and the restricting wall portion moves to the Tojiri side of the inner shoji 3. Thereby, even if it is a case where the inner shoji 3 and the outer shoji 4 are deform | transformed so that it may be heated and expand | extended, a control wall part and the pin 21 will engage, and it will go to the direction of finding the inner shoji 3 and the outer shoji 4 The deformation of is regulated. For this reason, it is possible to suppress the deformation of the inner shoji 3 and the outer shoji 4 and prevent a gap from occurring in the summing portion of the inner shoji 3 and the outer shoji 4.

  In the said embodiment, although the 2nd member which can be relatively moved with the regulating member 20 with the sliding of the shoji was used as the pin 21, it does not restrict to this. For example, a fixed portion fixed to the Tojiri ridge 48 of the external shoji 4, an insertion portion inserted into the notch portion 20c from the end of the fixed portion toward the inner limb, and a restriction member extending from the distal end of the insertion portion The inner wall portion of the 20 fixed wall portion 20a located on the side of the inner limb has a U-shape, and the restriction wall portion 20b and the inner wall portion of the restriction member 20 deformed by heating can be engaged with each other. It doesn't matter.

  In the above embodiment, the description has been given by taking as an example the deformation restricting structure of the shoji, in which the restricting member 20 is provided on the Tojiri 38 of the inner shoji 3 and the pin 21 is provided on the Tojiri 48 of the shoji 4. The member 20 may be provided on the Tojiri heel 48 of the external shoji 4 and the pin 21 may be provided on the Tojiri heel 38 of the inner shoji 3.

  Moreover, in the said embodiment, although demonstrated taking the example of the draw-joint joinery, not only this but the joinery provided with the several sliding door shoji may be sufficient. Moreover, you may provide between the Tojiri sash of the shoji which makes a sliding door, and the vertical bone and wall surface which comprise this FIX window, for example facing this Tosoji heel. The sliding direction of the shoji is not limited to the left-right direction, and may be the up-down direction. In joinery whose sliding direction is the up-down direction, the summon fence and Tojiri-ancho are horizontal reeds whose longitudinal direction is the left-right direction, and the finding direction at that time is the up-down direction.

  According to the above embodiment, the U-shaped notch 20c is formed at the center in the vertical direction with the L-shaped horizontal section, and the restriction member 20 as a piece member has been described as an example. The regulating member may be screwed to the reinforcing member 10 at a distance corresponding to the vertical width L2 of the notch 20c of the above embodiment between the pair of regulating members having a substantially L-shaped horizontal cross section. In this case, the press work etc. for forming a U-shaped notch become unnecessary.

  In addition, the said embodiment is for making an understanding of this invention easy, and is not for limiting and interpreting this invention. The present invention can be changed and improved without departing from the gist thereof, and it is needless to say that the present invention includes equivalents thereof.
