Description

  The present invention relates to a sash including a shoji that moves in the left-right direction in a frame.

As shown in FIG. 11, the sliding sash shoji has a door block 91 made of hard resin attached to a door rod 90. The door-to-door block 91 has an inclined surface 93 that gradually toward the indoor side toward the fence frame 92. When the shoji 94 is closed, the inclined surface 93 abuts against the protruding piece 95 of the shovel frame, The door is drawn to the indoor side.
In the sliding sash, when the outdoor side becomes negative pressure and the shoji 94 is pressurized to the outdoor side, the entire shoji is deformed so as to swell outward. At this time, as shown in FIG. 11 (b), the shoji 94 is inclined to the outdoor side, and the tip of the protruding piece 95 of the eaves frame hits and is pressed against the inclined surface 93 of the door stop block 91. to force F _X of the load F applied to the projecting piece 95 pushes the door leading end along the dispersed inclined surface 93 on the sash plane direction of Tatewaku occurs, the tip of the protruding piece 95 along the inclined surface 93 As shown by the dotted arrow 96 in the figure, there is a problem that the door tip moves obliquely in the direction of the shoji plane, and the door tip is easily detached from the saddle frame 92.

The sliding sash described in Patent Literature 1 has a door-contacting piece 55 attached to a door-toe of a shoji door, an abutting surface 56 in the indoor / outdoor direction, and a diagonal shape for drawing the door-to-door toward the indoor side when closing the shoji. A slope 58 is formed between the surface 57 and the sloped surface toward the outdoor side gradually from the abutment surface toward the inclined surface. 58 is in surface contact with the guide protrusion 31 of the saddle frame to prevent a force from pushing the door tip in the inward direction of the shoji, thereby preventing the door from coming off.
However, this door stop piece cannot suppress the deformation of the shoji and the tilt of the door. If the shoji is bent and the door is tilted to the outside of the door, the door will move in the direction of the shoji. . The slope 58 of the door stop piece is provided continuously with the inclined surface 57 for pulling the door to the indoor side. Since the width of the slope 58 is not so wide, the shoji is strongly pressed to the outdoor side. If the shoji bends greatly, the tip of the guide ridge 31 of the saddle frame is released from the inclined surface 58 and pressed against the inclined surface 57. Then, a force is generated to push the door toward the inside of the shoji, so the door is removed. There is a fear.

  An object of the present invention is to provide a sash that can reliably prevent the door end of the shoji from coming off even when the shoji is strongly pressed to the outdoor side.

  In order to achieve the above object, a sash according to a first aspect of the present invention includes a frame body and a shoji that is housed in the frame body so as to be movable in the left-right direction, and the frame body projects toward the inner peripheral side of the frame. There is a piece, and the shoji has a door-to-door block attached to the door toe, and the door-to-door block has a drawing portion and a receiving portion. It has an inclined surface that draws the door to the indoor side and can be displaced indoors and outwards by elastic force. The receiving part faces the indoor side surface of the protruding piece of the frame frame with a gap, and the drawing part is on the indoor side. It is characterized by receiving the indoor side surface of the protruding piece when it is displaced into the position.

  In the sash according to the second aspect of the present invention, in addition to the structure of the first aspect, the door stop block has a clearance surface facing the interior side surface of the protruding piece on the door bottom side of the receiving portion with a gap. It is characterized by.

  The sash according to the invention described in claim 3 is characterized in that the flank is an inclined surface that goes toward the outdoor side as it goes toward the frame.

  In the sash according to the first aspect of the present invention, when the shoji is pressurized to the outside by negative pressure on the outdoor side or the like, the pulling portion of the door-to-door block is displaced to the indoor side, and accordingly the door of the shoji The tip moves to the outside of the room. Thereby, since the inclination of the door tip of a shoji is suppressed small and the amount by which the door tip moves in the in-plane direction of the shoji also becomes small, it is possible to make it difficult to remove the door tip. Further, when the drawing portion is displaced to the indoor side, the receiving portion of the drawing block receives the indoor side surface of the protruding piece, so that the drawing portion can be prevented from being damaged, and the receiving portion is locked to the protruding piece so that the door tip It can be prevented from coming off.

  Further, in the sash according to the second aspect of the present invention, the door stopper block has a flank facing the interior side surface of the protruding piece on the door bottom side of the receiving portion with a gap therebetween, so that the shoji is pressurized to the outdoor side. When the receiving part receives the indoor side surface of the projecting piece, the flank is separated from the projecting piece, so that it is possible to prevent a force from pushing the door tip inward in the shoji plane. Is more difficult to come off from the protruding piece, and the effect of making it difficult to remove the door can be enhanced.

  In the sash according to the third aspect of the present invention, the shoji is pressurized to the outdoor side and the receiving portion is pressed to the outdoor side as in the second aspect of the present invention by making the flank face an inclined surface toward the outdoor side as it goes toward the frame. When receiving the indoor side surface of the projecting piece, the slope is separated from the projecting piece, preventing a force from pushing the door tip in the direction of the shoji plane and preventing the door from coming off. Furthermore, when the pressure on the outdoor side of the shoji increases, and when the slope comes into surface contact with the indoor side of the protruding piece, there is no force to push the door toward the inside of the shoji, and the door no longer has a room. There is an action to prevent it from leaning outward.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 9 is a cross-sectional view of the sliding sash. In this sliding sash, a frame 25 formed by four-round frames of an upper frame, a lower frame 24, and left and right frame frames 5a and 5b is provided at the building opening of the building. In the frame body 25, the inner shroud 4a and the outer shroud 4b are housed in a frame 25 so as to be movable in the left-right direction along rails 26a, 26b provided in the longitudinal direction of the upper and lower frames. The left and right hook frames 5a and 5b are provided with projecting pieces 6a and 6b that are inserted into the grooves 10 on the outer peripheral side of the door rods 9a and 9b of the inner and outer shojis 4a and 4b so as to protrude toward the inner peripheral side of the frame. Door-to-door blocks 1a and 1b are attached to the door rods 9a and 9b of the inner and outer shoji.

  As shown in FIGS. 2 and 4, the door rods 9 a and 9 b have a groove 10 on the outer peripheral side, a tight material holder 12 is provided on the outdoor wall 11 of the groove 10, and a tight material 13 is provided on the tight material holder 12. Is installed. As for the indoor side wall 14 of the groove | channel 10, the front-end | tip part is bent toward the outdoor side, and the notch 15 is provided in the attachment position of the door stop blocks 1a and 1b as shown in FIG.4 (b). .

FIG. 3 shows a first embodiment of a door-to-door block 1a attached to the door-toe 9a of the inner shoji 4a. The door stop block 1a is integrally formed of a hard resin, and has a plate-like portion 16 disposed at the bottom of the groove 10 of the door-end rod 9a, and a raised portion 17 that rises from the plate-like portion 16 to the door-end side, The plate-like portion 16 and the raised portion 17 form a substantially L-shaped attachment portion 3 in plan view.
Receiving portions 28, 28 are provided at the upper and lower portions of the outdoor side finding surface of the raised portion 17, and the drawing portion 2 is provided between the receiving portions 28, 28. The receiving portion 28 is a vertical surface perpendicular to the indoor / outdoor direction. Further, at the corner portion between the receiving portion 28 and the plate-like portion 16, a backlash stopping portion 20 is formed so as to protrude. A fitting recess 21 that fits with the edge of the indoor side wall 14 of the door rod 9a is provided at the corner on the indoor side of the raised portion 17.
As shown in FIG. 3B, the drawing portion 2 has a U-shaped cut 18 formed in the middle portion in the vertical direction of the raised portion 17, as shown in FIG. 2B and FIG. 3D. In addition, it is formed in the shape of a cantilever leaf spring that extends obliquely outward from the top of the raised portion 17 toward the distal end side of the protruding piece 6a of the flange frame 5a. An inclined surface 7 is provided. The pulling portion 2 protrudes to the outdoor side from the receiving portion 28, and the leading end portion of the pulling portion overlaps with the backlash stopping portion 20 when viewed from above.
An elastic deformation portion 22 for attachment extending obliquely from the plate-like portion 16 to the door end side is provided in the middle portion in the vertical direction on the indoor side of the door stop block 1a. The elastic deformation part 22 for attachment is provided with a fitting part 23 that fits into the notch 15 of the door rod 9a at the tip part.
The door-to-door block 1b for the external shoji 4b is different from the above-mentioned door-to-door block 1a for the internal shroud 4a.

  When the door stop block 1a is mounted in the groove 10 of the door toe 9a, as shown in FIG. 5A, the tip of the plate-like portion 16 is placed between the tight material holder 12 and the groove bottom surface through the opening of the groove 10. If the mounting portion 3 is pushed in toward the groove bottom, the mounting elastic deformation portion 22 is elastically deformed and inserted entirely into the groove 10, and when inserted, as shown in FIG. The elastically deforming portion 22 is restored, and the fitting portion 23 is fitted into the notch 15 of the door-end rod 9a, and the edge of the indoor side wall 14 of the door-end rod 9a is fitted into the fitting recess 21, so that the attachment portion 3 is fixed in the groove 10. As described above, the main door block 1a can be easily mounted in the groove 10 of the door toe 9a from the outer peripheral side of the shoji, and can be stably moved without rattling or moving without screwing or the like. Can be installed inside.

  When closing the inner impeller 4a, as shown in FIG. 2 (a), the protruding piece 6a of the collar frame 5a abuts on the inclined surface 7 of the door-to-door block pulling portion 2, so that the door tip of the inner impeller 4a is moved. When it is gradually drawn toward the room side and the inner impeller 4a is fully closed, as shown in FIG. Stops and prevents the door from rattling. At this time, the tight material 13 attached to the door-end fence 9a is brought into close contact with the outdoor side surface of the protruding piece 6a of the fence frame 5a, thereby preventing the entry of wind and rain from between the door-end fence 9a and the fence frame 5a. There is a gap between the receiving portion 28 and the indoor side surface of the flange frame protruding piece 6a.

  FIGS. 1A to 1C show a state in which the door tip moves when the outdoor side becomes negative pressure and the inner shovel 4a is pressurized to the outdoor side. The pressure P which pushes the inner shoji 4a to the outdoor side is large in the order of (a) to (c). When the pressure P pushing the inner impingement 4a is small, as shown in FIG. 1 (a), as the inner impeller 4a is curved and deformed so as to bulge to the outside, It tilts slightly to the outdoor side with the contact part with the protruding piece 6a as a fulcrum. When the pressure P that pushes the inner shoji 4a becomes larger, as shown in FIG. 1 (b), the door toe bar 9a slightly moves to the left side, and the back stopper 20 of the door stop block 1a is a protruding piece of the bar frame 5a. 6a, and then the pulling portion 2 of the door stop block 1a is pushed by the protruding piece 6a of the frame 5a and is elastically deformed so as to bend indoors, and the door rod 9a moves straight to the outdoor side accordingly. . When the pressure P pushing the inner impingement 4a is further increased, as shown in FIG. 1 (c), the pulling portion 2 of the door stop block 1a is further bent to the indoor side, and the inclined surface 7 is in surface contact with the indoor side surface of the protruding piece 6a. Then, the door toe 9a further moves to the outdoor side, and the receiving portion 28 of the door stop block 1a receives the indoor side surface of the protruding piece 6a. The inclination angle of the door rod 9a hardly changes between (a) to (c). Even if the door toe 9a moves to the outdoor side and the tight material 13 moves away from the protruding piece 6a of the frame 5a, wind and rain are not blown into the indoor side because the outdoor side has a negative pressure.

  Thus, even if the pressure P which pushes the inner impingement 4a becomes large, the draw block 2 is elastically deformed and the door block 1a moves to the indoor side, and the door toe 9a moves to the outdoor side. For this reason, the inclination of the door toe fence 9a can be kept small, and the amount of movement of the door toe in the direction of the shoji plane is also reduced, so that the door toe fence 9a has a function of making it difficult to come off the fence frame 5a. Further, since the inclined surface 7 of the pulling portion 2 is in surface contact with the indoor side surface of the protruding piece 6a of the frame frame, the load F1 applied to the protruding piece from the pulling portion 2 is not dispersed, and the door tip is directed in the direction of the shoji plane. Since the pushing force does not occur, the door is hard to come off from this. Further, the door block 1a is provided with receiving portions 28 above and below the pulling portion 2, so that the pulling portion 2 can be prevented from being bent excessively and the load is distributed to the pulling portion 2 and the receiving portion 28. Therefore, damage to the drawing portion 2 can be prevented. Moreover, it can prevent that a door tip remove | deviates because the receiving part 28 latches to the protrusion piece 6a. Since it is not necessary to provide the receiving portion 28 with the inclined surface 7 for pulling the door to the indoor side, the width of the receiving portion 28 can be increased, thereby increasing the amount of engagement with the protruding piece 6a. It is possible to reliably prevent the door from coming off.

  The same applies to the external shoji 4b. That is, when closing the outer panel 4b, the protruding piece 6b of the collar frame 5b comes into contact with the inclined surface 7 of the drawing portion 2 of the door stop block 1b, and the door tip is drawn indoors. When the outdoor side becomes negative pressure and the external door 4b is pressurized to the outdoor side, the pulling portion 2 of the door stop block 1b is pushed by the protruding piece 6b of the eaves frame 5b and elastically deforms to the indoor side, and the door tip Moves to the outdoor side, and the inclination of the door is kept small, so that the door is less likely to come off from the frame 5b.

FIG. 6 shows a second embodiment of the door block 1 according to the present invention, FIG. 7 is a cross-sectional view of the sliding sash door when the door block 1 is used, and FIG. Similarly, it is a cross-sectional view of the sliding sash door contact portion, and the state when the outdoor side becomes negative pressure and the inner limb 4a is pressurized to the outdoor side (the state of FIG. 1 (c) in the first embodiment) Equivalent).
As shown in FIG. 7, the door stop block 1 a is provided with a slope 8 between the door bottom side of the receiving portion 28 and the backlash stopper 20 toward the outdoor side as it goes toward the flange frame 5 a. The inclination of the slope 8 is about 12 °. Other parts are almost the same as those of the first embodiment. According to this door stop block 1, as shown in FIG. 8, the inner shoji 4a is pressurized to the outdoor side, the pulling portion 2 of the door stop block 1a is displaced to the indoor side, and the receiving portion 28 of the protruding piece 6a When the indoor side surface is received, the inclined surface 8 is separated from the protruding piece 6a, and the tip of the protruding piece 6a is not pressed against the door stop block 1a toward the indoor side, so the load F2 applied to the protruding piece from the receiving portion 28 Is not dispersed and no force is generated to push the door tip in the direction of the shoji plane, so that the door tip can be more reliably prevented from coming off. In addition, since it is not necessary to provide the receiving portion 28 with an inclined surface for drawing the door to the indoor side, the width of the inclined surface 8 can be increased, thereby increasing the amount of engagement with the protruding piece 6a. It is possible to reliably prevent the tip from coming off. When the pressure P that pushes the inner impingement 4a to the outdoor side becomes stronger than the state shown in FIG. 8, the door tip of the inner impingement 4a further tilts outward, and the slope 8 and the indoor side surface of the protruding piece 6a come into surface contact. When the inclined surface 8 comes into surface contact with the indoor side surface of the protruding piece 6a, in addition to the force that pushes the door tip inward in the shoji plane, there is an effect of preventing the door tip from further tilting to the outdoor side.

  In the second embodiment, the slope 8 is inclined at a smaller angle (for example, around 5 °), and the slope 8 comes into surface contact with the indoor side surface of the protruding piece 6a at a stage where the pressure on the outdoor side of the inner impeller 4a is smaller. It can also be done.

  The present invention is not limited to the embodiments described above. The inclined surface of the pulling portion of the door-to-door block may be a curved inclined surface. The drawing part may have a shape extending from the bottom side of the groove on the outer periphery of the door toe toward the door toe. The receiving part of the door stop block may be provided only on either the upper side or the lower side of the attracting part. As shown in FIG. 10, the flank of the pulling block may be formed with a recess on the door bottom side of the receiving portion 28, and a surface perpendicular to the indoor / outdoor direction corresponding to the bottom surface of the recess may be used as the flank 29. The sash of the present invention can also be applied to a one-way sash.
