Description

    The present invention relates to a shoji closing device for a window supported by an arm protruding outward from a window frame such as a sliding window, a push-up window, and a natural wind ventilation window, and a window. Here, the natural wind ventilation window refers to a window in which ventilation is performed by opening and closing the shoji naturally depending on the state of the inside air and the wind force applied to the shoji generated by the outside air.

    The upper part of the shoji is pivoted with a pin to the frame of the window frame and is pushed out. The lower end of the arm whose upper end is pivotally attached by a pin to the saddle's collar is fitted with a pin or roller provided in the collar frame by a long hole provided in the arm.

    In order to open and close this shoji, a rod whose one end is pivotally attached to the lower arm by a ball joint, and one end which is connected to the opening / closing drive device by a vertical axis is connected to the other end by a ball joint. An arm is provided.

    In this way, the shoji arm is closed by the lock mechanism while pulling the shoji to the indoor side. The shoji is released by releasing the lock mechanism and extending the character arm. The shoji opening / closing device is provided with an opening / closing drive device on the lower side of the window frame so as to travel on the indoor side.

    Accordingly, the character-shaped arm is always exposed and lacks in design. The clasp-shaped arm is easy to get dirty and difficult to clean. Since the opening / closing drive device makes a business trip from the lower frame to the indoor side, the protruding object protrudes into the room. Therefore, if the character arm and the opening / closing drive device are used for the window, the projecting object is juxtaposed to the room side from the window that is continuously provided, so that the design of the whole room is damaged. Also, in the natural wind ventilation window, the shoji switching device must not disturb the opening and closing of the shoji when the shoji is open, so it is necessary to release the square arm or disconnect the switching drive device from the square arm and disable it .

    Since there is a rounded arm in the window frame, even if a louver or blind is provided, the louver or blind cannot be lowered to the lower frame. When the curtain is provided, the skirt is inflated by the opening / closing drive device, and the design of the curtain is damaged.

    The shoji opening and closing device using the above-mentioned character arm is also used in the sliding window using the rotary sliding mechanism.

The natural wind ventilation window opens with no wind and closes with a positive pressure (pressure applied to the shoji by the wind blowing from the outside toward the window). However, when the wind power fluctuates due to strong winds, the shoji screen closes rapidly with positive wind. Also, the shoji can be opened quickly by negative pressure. The generated sound is particularly loud when the shoji screen closes rapidly. Therefore, a shoji closing device that normally functions as a natural wind ventilation window and closes the shoji when the wind is strong is provided.

Thereby, the airtightness between the shoji 2 and the window frame 1 is measured. The inner surface materials 21c, 22a, and 23a are on one plane parallel to the wall surface when the shoji 2 is closed.

  The shoji 2 has outer inner surface materials 21d and 22b facing the inner side on the outer side than the inner surface materials 21c, 22a and 23a. These are on a plane parallel to the wall surface when the shoji 2 is closed.

  A packing 49 that comes into contact with the outer inner surface material 22b of the upper collar 22 when the shoji 2 is closed is fitted to a strip 12d provided on the door stopper 12b of the upper frame 12. The strips 11e and 12d have a gate shape when viewed from the expected direction, and the packing 49 is also disposed in the same manner.

  When the shoji 2 is closed, the outer side inner members 21d and 22b of the shoji 2 and the upper shochu 22 of the shoji 2 come into contact with the packing 49 to measure water tightness when the shoji 2 is closed. Sealing in a gate shape as described above prevents rainwater and the like from entering between the window frame 1 and the shoji 2.

  When the shoji 2 is closed, a space that is long in the vertical direction is surrounded by the outer peripheral member 21b of the collar 21 of the shoji 2, the packing contact portion 21f of the outer inner member 21d, the inner peripheral member 11a of the vertical 11A, the plate member 11c, and the protrusion 11d.

Both of these are abutted and fixed to the frame 11 and the vertical 11A. In other words, the lower frame 13, the saddle frame 11, and the vertical 11A are configured in a saddle direction member win. The stand 11A extends below the window X. The front surface seen from the inner side of the portion extending downward from the vertical 11A is a wall surface WA (see FIG. 5). It is also possible to connect another window under the window X to form a step window.

  As shown in FIG. 6, the cover 11n has a U-shaped cross section. To attach the cover 11n to the stand 11A, when the cover 11n is slightly inclined substantially vertically and pushed outward from the indoor side into the edge 11q of the plate 11p, the edge 11q is rounded, so the fitting edge The space between 11k and 11k is enlarged by the edges 11q and 11q, and the protrusion 11k1 provided on the fitting edge 11k gets over the edge 11q, so that the edge 11q hits the inclined portion 11k2 of the fitting edge 11k. Therefore, when the cover 11n is pushed outward as it is, the end of the inclined portion 11k2 is fitted to the outside of the edge 11q, and the tip of the fitting edge 11k is fitted to the vertical cut groove 11g.

  If the cover 11n is pushed in so that it is vertical, the cover 11n is locked to the vertical 11A.

  The additional lower frame 13B shown in FIG. 7 is fitted to the lower frame main body 13A by the fitting portion 13a. The additional lower frame 13B is provided with a groove 13b that opens upward. An interlocking rod, which will be described later, is fitted to the groove 13b so as to be movable along the groove 13b.

  In the above, the main arm frame side fixture 18 and the pin 26 are made of stainless steel.

(Buffer stopper)
In this example, when the shoji 2 is closed, a buffer stopper is provided for facilitating the opening of the shoji 2 and mitigating the impact of the shoji 2 that is going to be closed by a strong wind. As shown in FIGS. 1 and 2, a buffer stopper 15 having an arm 15e parallel to the main arm 3 is attached to the vertical frame 11 and the vertical 11A immediately below the main arm 3.

8, 9, and 10 show the buffer stopper 15, FIG. 8 is a side view, FIG. 9 is a front view, and FIG. 10 is a plan view.
A shaft 15c is rotatably provided on a frame side bracket 15b fixed to the protrusion 11d of the vertical 11A with a small screw 15a. The shaft 15c is parallel to the wall surface and faces the horizontal direction. One end of the torsion coil spring 15d extrapolated to the shaft 15c is locked to the shaft 15c, and the other end is fixed to the frame side bracket 15b. The torsion coil spring 15d is fitted in a horizontal circular hole 15b1 parallel to the wall surface of the frame side bracket 15b. A door stop roller 15f is rotatably provided at the tip of an arm 15e whose root is fixed to the shaft 15c. The arm 15e is biased counterclockwise by a spring 15d in FIG.

    In FIG. 8, the torsion coil spring 15d is in a free state when the arm 15e and the door stop roller 15f are in a two-dot chain line state. When the shoji 2 is closed, the door contact roller 15f comes into contact with the packing contact 21f of the shoji 2 and as the shoji 2 is closed, the arm 15e moves to the indoor side (right side) in FIG. When 2 is completely closed, the position becomes a solid line. At this time, the buffer stopper 15 is housed in the space S.

    As will be described later, when the sub-arm pulling device 6 is released, the shoji 2 can be freely opened. At this time, since there is a buffer stopper, the shoji 2 is actuated at the beginning of opening and the shoji 2 is fixed to the window frame 1 or the like. Even if there is, it gives a chance to start opening. Also, when the shoji 2 tries to close rapidly in a strong wind, the door stop roller 15f hits the packing contact material 21f of the shoji 2, and the torsion coil spring 15d is gradually tightened.

(Sub arm mounting configuration)
As shown in FIG. 1 and FIG. 2, a subarm shoji-side attachment 28 having a substantially simple shape is attached to an intermediate portion of the collar 21 of the shoji 2.

It is fixed. This plate is made of stainless steel.

  The upper end of the sub arm 4 is in contact with the fixture 28. The pin 31 is screwed into the sub arm shoji side fixture 28 through the hole at the upper end of the sub arm 4. The upper end of the sub arm 4 is rotatably fitted to the pin 31.

  The sub arm frame side fixture 32 is in contact with the inner peripheral material (the vertical protrusion 11d) in the lower part of the flange frame 11 and the vertical frame 11A. The machine screw 32a that passes through the hole of the fixture 32 is screwed into a not-shown abutting plate provided on the back surface of the inner peripheral member through the inner peripheral member on the side of the collar frame. On the side of the vertical 11A, the sub arm attachment 32 is brought into contact with both sides of the protrusion 11d, and a small screw passing through one of the sub arm attachment 32 and the protrusion 11d is screwed and fixed to the other sub arm attachment 32 ( Neither is shown).

  The sub arm frame side fixture 32 integrally has a pin 32b with a horizontal center line parallel to the wall surface. A hole at the lower end of the sub arm 4 is rotatably fitted to the pin 32b.

  In order to determine the rotation limit when the sub arm 4 is rotated to the outside, a stopper 34 is provided so that the sub arm 4 contacts and does not rotate any further. The stopper 34 is integrally or welded to the sub arm frame side fixture 32, and protrudes on the rotation trajectory of the sub arm 4.

(Main arm and sub arm mounting positions)
The attachment positions of the main arm 3 and the sub arm 4 of this embodiment will be described.

    52 and 53 are schematic longitudinal sectional views of the natural wind ventilation window schematically shown. FIG. 52 shows a state in which the shoji 2 is closed, and FIG. 53 shows a state in which the shoji 2 is opened.

  For dynamic explanation, the pin 17 described above is represented as a main arm shoji side fulcrum 3a, the pin 26 as a main arm frame side fulcrum 3b, the pin 31 as a sub arm shoji side fulcrum 4a, and the pin 32b as a sub arm frame side fulcrum 4b. .

  As shown in FIG. 52, when the shoji 2 is closed, the shoji 2 is upright. The center of gravity CG of the shoji 2 at that time is approximately the center in the vertical direction of the shoji and near the indoor side of the glass surface. The fulcrum 4a is located. The main arm frame side fulcrum 3b and the sub arm frame side fulcrum 4b are located on the indoor side of the plane. Here, the angle that the main arm 3 makes with the plane PL is θ1, and the angle that the sub arm 4 makes with the plane PL is θ2. If the angles formed by the respective arms 3 and 4 counterclockwise from the plane PL with the shoji side fulcrums 3a and 4a as the center are the positive angles, the angles θ1 and θ2 are the positive angles. There is no problem even if the shoji side fulcrums 3a and 4a are outside the plane PL passing through the center of gravity of the shoji, but the frame side fulcrums 3b and 4b must be indoors. In the above description, the angles θ1 and θ2 are both small and θ1> θ2.

  In this example, the center of gravity CG of the shoji 2 is below the main arm shoji side fulcrum 3a and the sub arm shoji side fulcrum 4a. Therefore, the angle α2 formed by the perpendicular line passing through the sub arm 4 and the sub arm shoji side fulcrum 4a when the shoji 2 is opened can be made small.

  Here, looking at the force to open the shoji 2 when the shoji 2 is closed, the weight W of the shoji 2 is W on the fulcrums 3a and 4a under the condition that the shoji side fulcrums 3a and 4a are on the plane PL. / 2 is added. Therefore, when the load W / 2 applied to the fulcrum 3a is decomposed into a force along the main arm 3 and a force orthogonal to the main arm 3, the force orthogonal to the main arm 3 becomes W / 2 · sin θ1. Assuming that the length of the main arm 3 (the distance between the fulcrums 3a and 3b) is L1, the moment M1 = L1 that attempts to rotate the main arm 3 around the frame-side fulcrum 3b by the load of the shoji 2 W / 2 · sin θ1. Further, when the load W / 2 applied to the fulcrum 4a is decomposed into a force along the sub arm 4 and a force orthogonal to the sub arm 4, the force orthogonal to the sub arm 4 becomes W / 2 · sin θ2. Assuming that the length of the sub arm 4 (the distance between the fulcrums 4a and 4b) is L2, the moment M2 = L2 · W that tries to rotate the sub arm 4 around the frame side fulcrum 4b by the load of the shoji 2 / 2 · sin θ2.

  When the shoji 2 is opened, the main arm 3 and the sub-arm 4 rotate counterclockwise about the frame side fulcrums 3b and 4b and stop by contacting the stoppers 18a and 34, respectively. In 53, the stopper is in the position (not shown). In this windless state, ventilation is performed.

The balance of the force when the shoji 2 is opened and the main arm 3 and the sub arm 4 are in contact with the stoppers 18a and 34 is as follows. When the horizontal distance between the main arm shoji side fulcrum 3a and the sub arm shoji side fulcrum 4a is A, and the horizontal distance between the shoji gravity center CG and the main arm shoji side fulcrum 3a is B, the vertical load applied to the shoji side fulcrum 4a of the sub arm 4 is Since P2−P1 = W and P2 · A = BW, P2 = (B / A) · W. Further, an upward force is applied to the main arm shoji side fulcrum 3 a based on the weight of the shoji 2. The upward vertical load P1 = W · (B−A) / A. Therefore, the component perpendicular to the main arm 3 of the load P1 is P1 · sin α1 = (W · (B−A) /), where α1 is the angle between the main arm 3 having the main arm shoji side fulcrum 3a as a vertex and the perpendicular. A) ・ sinα1
Therefore, the moment of M3 = (W · (B−A) / A) · sin α1 · L1 acts on the upper side of the shoji 2 around the main arm frame side fulcrum 3b and a force to close the upper side of the shoji 2 is generated. Yes.

  Here, since the load generated based on the weight of the shoji 2 is downward on the sub arm shoji side fulcrum 4a, a counterclockwise moment M4 is produced on the sub arm 4 so that the shoji 2 is opened.

  The moment M4 for opening the shoji 2 is M4 = P2 · sin α2 · L2 where L2 is the distance between the fulcrums 4a and 4b of the sub arm 4 where α2 is the angle between the direction of the force P2 and the sub arm 4. And it is set so that M3 <M4, and these differences are made small. Therefore, when there is no wind, the shoji 2 does not move in the direction in which the shoji 2 is closed while the shoji 2 is open.

  Considering the above points, the lengths of the main arm 3 and the sub arm 4 and the positions of the fulcrums 3a, 3b, 4a, 4b are set.

  With such a setting, the shoji 2 naturally and gently opens from the closed position when there is no wind. For example, when the wind blows from the outside of the shoji 2 to the shoji 2 surface from the crossing direction, the shoji 2 is closed by the wind pressure. 53, the main arm 3 rotates clockwise around the frame side fulcrum 3b in FIG. 53, and the sub arm 4 rotates clockwise around the frame side fulcrum 4b. Therefore, the shoji 2 closes when the wind is strong. However, when the wind is low, the shoji 2 is in a slightly open state and the outside air is blown into the room. The reason why the shoji 2 is closed also by this breeze is that the fulcrum 4a is above the shoji center of gravity CG, the angle α2 is small, and the wind force applied to the entire surface of the shoji 2 becomes a force toward the indoor side. This is because the main arm 3 is in a balanced state in which the main arm 3 tends to rotate toward the indoor side.

    The shoji 2 does not have an opening / closing device, and naturally opens and closes with wind power of the window.

  In such a natural wind ventilation window, a gust of wind blows during a storm and sudden positive pressure is applied to the shoji 2 from the outside toward the indoor side, or the wind direction changes and suddenly negative pressure is applied to the shoji 2 in the opposite direction. The shoji that has been closed and closed suddenly opens. Therefore, it is necessary to provide a shoji closing device that does not disturb the natural ventilation operation in case of storms or strong winds.

Pulling the above-mentioned sub-arm is effective as a shoji closing device. The sub arm pulling device can close the shoji 2 just by pulling the sub arm.
-Since the position where the pulling force is applied when pulling the sub arm can be selected, the pulling force and the pulling stroke can be selected, and there is flexibility in design. When the lower arm of the shoji is drawn as in the conventional example, a large process is required.
・ Because it can fit between the shoji screen and the window frame, the aesthetics of the window will not be damaged by the shoji closing device.
・ Considering the case where a large number of natural wind ventilation windows are installed in one building, the shoji closing device can be installed at the factory for the window frame with shoji, so productivity is high.

(Spring force)
The spring force of a tension coil spring (hereinafter simply referred to as a spring) 62 of the sub arm pulling device 6 and a tension coil spring (hereinafter simply referred to as a spring) 96 provided in the latch device 20R will be described. As shown in FIG. 11, when the shoji 2 is fully opened, the spring force of the spring 62 is contracted against the resistance applied via the interlocking rod 5. When the spring 62 is contracted, the wire 8 between the first pulley 36 and the sub arm 4 is in a state of being substantially straight or slightly slack without tension. At this time, the spring fixture 94 is pulled to the right end in FIG. 31 through the interlocking rod 5, the wire 80, the interlocking rod 95, and these connecting members, and the spring 96 is extended. At this time, in the direction parallel to the lower frame 13, the latch 20 and the latch receiver 101 need to be separated to a position where they cannot be engaged, and the spring forces of the springs 62 and 96 are large enough to satisfy this requirement. Of course, the interlocking rod 5 is added with the resistance of the handle device described later, and the spring force of the spring 62 is much larger than the spring force of the spring 96.

  The spring force of the spring 96 tensions the wire 80 by pulling the interlocking rod 95 in a state where no tension is applied to the wire 8 (when the interlocking rod 5 is located at a lower limit position where the interlocking rod 5 is pulled down by the handle device described later).

  The pusher 122 is provided in cylindrical holes 124a and 124b of the housing 124 fixed to the mounting frame portion 35e of the guide member 35 by a small screw 123 so as to be able to advance and retract toward the handle 111 along the moving surface of the handle 111. . The pusher 122 has a piston part 122a that slides into the hole 124a, a plunge part 122b that slides into the hole 124b and protrudes to the outside, and a spring seat 122c at the rear part. A compression coil spring 125 is contracted between the spring seat 122 c and the bottom plate 124 d of the housing 124.

  In FIG. 34, when the notch 119 rises from the recess 111d of the receiver 111c at the tip of the handle 111 and moves away from the edge 111c1 of the receiver 111c, the pusher 122 presses the back of the handle 111 with the spring force of the compression coil spring 125. 111 is rotated around the rotation shaft 113 and pushed out. The piston part 122a of the pusher 122 abuts on the step part 124c between the holes 124a and 124b of the housing 124, and the pusher 122 stops. At the stop position of the pusher 122, the concave portion 111d of the receiver 111c at the tip of the handle 111 protrudes outward from the outer surface of the cover 11n to the extent that a human finger can be hooked.

  When the handle 111 is opened by the pusher 122 as shown in FIGS. 34 to 35, the spur gears 114 and 115 in a state where the handle 111 is housed in the case 11n as shown in FIG. Meanwhile, there is no backlash of teeth between the spur gear 115 and the rack 116, and the rotation angle of the handle is small.

(Locking device)
43 to 46 show the locking device.

  As shown in FIG. 45, the joint material 126 abuts on the interlocking rod 5, the joint material 126 and the interlocking rod 5 are inserted, and the machine screw 127 is screwed into the back plate 128 provided in contact with the back of the interlocking rod 5, The joint material 126 and the interlocking rod 5 are fixed. 45, the first material 126a fixed to the inverted L-shaped interlocking rod 5 and the second material 126b fixed to the interlocking arm 131 are integrated with a small screw 126c. The joint material 126 is in contact with the upper end of the interlocking arm 131 and is fixed by welding. The interlocking arm 131 hangs down from a portion fixed to the joint material 126.

  As shown in FIG. 46, the interlock arm 131 passes through the case 133 of the lock device 132. The case 133 is long in the vertical direction and has a hollow rectangular horizontal section and an end plate 133e. A guide hole 133a for movably guiding the interlocking arm 131 is provided in the both end plates 133e.

  As shown in FIG. 47, the interlocking arm 131 after passing through the case 133 is fixed to the joint material 135 attached to the notch case 134 holding the notch 119 with a small screw 137 via a liner 136.

  The handle device has a lock device, and the lock device is provided with a notch device. Here is a description of the notch device.

(Notch device)
The notch device is shown in FIGS.

  The notch 119 is fitted in the notch case 134 so as to freely enter and exit in the vertical direction, and is urged downward by a spring (not shown). The tip of the notch 119 has a slope 119a so that the notch 119 is pushed into the notch case 134 by the edge 111c1 of the receiver 111c when the receiver 111c of the handle 111 moves in the direction of the arrow B in the figure. When the edge 111c1 of the receiver 111c passes the inclined surface 119a, the notch 119 enters the recess 111d of the receiver 111c from the notch case 134 by a spring force (not shown) to hold the handle 111. At this time, the outer surface of the handle 111 and the side surface of the cover 11n are substantially on the same plane with the outer surface of the handle 111 slightly outside.

  As shown in FIGS. 34 and 35, a transparent acrylic plate 143 is provided on the upper edge side of the handle storage hole 11r. In the state where the notch case 134 is lowered and the notch 119 is fitted in the recess 111d of the handle 111 as shown in FIG. 35, the notch case 134 is provided with a “closed” character that can be seen through the transparent acrylic plate 143 (see FIG. 48). ). As shown in FIG. 49, the transparent acrylic plate 143 is supported by the mounting frame portion 35e with a bracket 144. The cover 11n is provided with an opening 11n2 having a transparent acrylic plate at a position corresponding to the transparent acrylic plate 143.

(Continuous lock device)
As shown in FIG. 46, the hollow case 133 is fixed to one flange of the Z-shaped steel-shaped mounting seat 138 with a machine screw 139. This fixing is performed by inserting a machine screw 139 into a back plate 145 that is inserted into the case 133 and is in contact with the side plate 133 c in the case 133. The other flange of the mounting seat 138 is in contact with the mounting frame portion 35 e of the guide member 35 and is fixed by a machine screw 137.

  The push button 140 has a substantially square pressing surface 140a, a portion having the pressing surface 140a is fixed, a square stem 140c smaller than the pressing surface 140a, and a case 133 is fitted to the wall surface so as to be movable in the horizontal direction, and is hollow in the vertical direction. Has a hollow rectangular slide 140d, and a pin portion 140b fixed inside the slide 140d. The stem 140 c slides into the hole 133 a of the case 133. The slide 140 d is in the case 133 and is in contact with the front plate 133 b and the rear plate 133 d facing the case 133. The pin portion 140b is fixed to the inner surface of the side plate 140e of the slide 140d. The pin portion 140b has a fixing portion 140b1 that is fitted into the hole 140f of the side plate 140e and caulked against the side plate 140e protruding from the side plate 140e.

  The small end of the conical coil spring 146 that is inserted into the hole 145a provided in the back plate 145 and is seated on the side plate 133c of the case 133 is inserted into the fixing portion 140b1 of the pin portion 140b and contacts the side plate 140e of the slide 140d. It has been reduced.

  In the push button 140, a pressing surface 140a to be touched with a finger slightly protrudes from the outer surface of the cover 11n and is substantially the same surface. At this time, the short pin portion 140b having a cylindrical shape is fitted into an oval recess 131a that is slightly longer in the vertical direction provided in the interlocking arm 131. Note that a through hole having the same shape may be used instead of the recess. When the shoji 2 is open, the interlocking arm 131 is stretched and biased upward by the spring force of the tension coil spring 62 (see FIGS. 13 and 14) that has been extended. The pin portion 140b just touches the lower side surface of the recess 131a.

  43 and 44, the push button 140 is pushed by the spring 146, the pin portion 140b is fitted in the recess 131a of the interlocking arm 131, the interlocking arm 131 is near the lowering limit, and the spring of the interlocking rod 5 is The interlocking rod 5 is fixed against the upward urging by 62.

    When the push button 140 is pushed against the spring force of the spring 146 in the direction toward the cover 11n, the push button 140 moves and the pin portion 140b is detached from the recess 131a of the interlocking arm 131. The interlocking arm 131 is pulled up together with the interlocking rod 5 by the spring force of the spring 62 (see FIGS. 13 and 14) urging the interlocking rod 5 upward. At this time, the notch case 134 fixed to the interlocking arm 131 also rises together with the interlocking arm 131 and the notch 119 is separated from the handle 111. The character “closed” provided on the notch case 134 that was visible through the transparent acrylic plate 143 moves into the case 11n, and the open character provided on the extension 141b of the cover material 141 is visible through the transparent acrylic plate 143. . Thereby, the shoji 2 can be known in the closed state and the open state.

(Blocking device below the handle device)
50 and 51 show the blocking device. In this example, the handle 111 rotates from the vertical position in a direction in which the tip is separated from the cover 11n toward the indoor side. The handle 111 is at a position offset to the inside of the cover 11n with respect to the rotation shaft 113. Therefore, when the handle 111 is rotated with its tip turned downward, the handle handle 111e is located behind the handle in a state in which the handle 111 is stored in the handle storage hole 11r (see FIGS. 34 to 36) that is the opening of the cover 11n. It is necessary to provide the lower edge 11r1 of the handle storage hole 11r so that at least the handle handle 111e enters the cover 11n rather than the end. The vicinity of the lower edge 11r1 of the handle storage hole 11r is open when the handle 111 is stored in the handle storage hole 11r. Therefore, a blocking device is provided.

    As shown in FIGS. 50 and 51, a flange of an angle steel bracket 148 abuts on the mounting frame portion 35 e of the guide member 35 and is fixed by a machine screw 147. A cover 151 is swingably attached to the bracket 148 by a pin 150 on the bracket 148. The pin 150 is provided close to the back surface of the cover 11n. A torsion coil spring 153 is inserted into a spring mounting shaft 152 planted in the cover 151. One end of the spring 153 is in contact with a spring receiving pin 154 implanted in the bracket 148, and the other end of the spring 153 is in contact with the back portion of the cap 151. The surface 151a of the cover 151 is substantially flush with the outer surface of the handle 111 when the cover 151 covers the lower portion of the handle storage hole 11r. In order to keep the cover 151 on the same surface, the cover 151 is provided with a contact surface 151b. The contact surface 151b is in contact with the inner surface 11n1 of the lower edge 11r1 of the handle accommodation hole.

In the above, the cover 151 is made of stainless steel like the handle pattern 111e.
When the handle 111 is housed in the handle housing hole 11r, the outer surfaces of the handle 111 and the cover 151 are on one plane and slightly protrude from the case 11n. Accordingly, there are no protrusions such as a gymnasium or a tightening handle that may hit the wall surface when a large number of people enter or exit. In addition, it has an excellent appearance in terms of design. Further, since the case 11n is covered with each cover material regardless of whether the handle is opened or closed, the device in the case is difficult to get dirty, and it does not accidentally drop an object in the case, so that maintenance is excellent.

In FIG. 34, when the handle 111 is housed in the handle housing hole 11r and is in a vertical state, the cover 151 is rotated by the spring force of the spring 153 to block the lower part of the handle housing hole 11r. In this state, even if the cover 151 is pushed toward the handle storage hole 11r, the protrusion 111p at the lower end of the handle 111 hits the upper end of the cover 151, and the cover 151 does not rotate into the handle storage hole 11r.
When the lock device 132 is released and the handle 111c at the top of the handle 111 is exposed to the outside as shown in FIG. 35, the handle 111 is rotated outwardly from the cover 11n clockwise in FIG. The handle pattern 111e is in contact with the upper edge of the cover 151 at a position rotated by θ = 12.5 degrees.

  When the handle 111 is further rotated, the handle handle 111e rotates counterclockwise in FIG. 50 toward the cover 11n around the pin 150 against the spring force of the spring 153. At this time, the upper edge of the cover 151 slides against the handle pattern 111e.

    From this point, when the handle 111 is rotated counterclockwise, the upper edge of the cover 151 slides on the handle handle 111e, and the cover 151 is rotated clockwise around the pin 150 by the spring force of the spring 153. 151b hits the inner surface 11n1 of the cover 11n and stops.

  During the operation, the cover 151 closes the opening below the handle housing hole 11r generated below the handle 111 from the beginning.

(Summary of overall action)
In the state where the shoji 2 by the handle device 25 is closed as shown in FIG. 1, the wire 8 pulls the sub arm 4 to the indoor side, and the spring 62 extends. The interlocking rod 5 is in the lower limit position. As shown in FIGS. 30 and 32, the latch 20 is engaged with the latch receiver 101 which is moved left by the spring force of the spring 96 (see FIG. 4), and the shoji 2 is prevented from moving outward.

    44 and 47, the pin portion 140b of the push button 140 of the locking device is fitted in the hole 131a of the interlocking arm 131 that has been lowered together with the interlocking rod 5, and is going to rise by the spring force of the spring 62. The interlocking arm 131 is locked. The notch 119 is engaged with the tip of the handle 111, and the handle 111 is accommodated in the cover 11n along the cover 11n.

When the push button 140 is pushed against the spring force of the spring 146 to open the shoji 2, the pin portion 140b of the push button 140 guided by the case 133 (see FIG. 46) comes out of the hole 131a of the interlocking arm 131. . Then, the spring 62 has the spring force of the spring 96 urging the latch receiver 101, the interlocking rods 5, 95, the sliding resistance between the interlocking arm 131 and these guide members, the rotational resistance of the pulley of the corner drive 70, and the like. Shrinks against this, and pulls up the interlocking rod 5 and the interlocking arm 131. At this time, the interlocking rod 5 rises without its long hole 5d acting on the pair of pins 118 provided on the joint material 117 fixed to the rack 116, and the lower end of the long hole 5d is the lower pin. Close to 118a. The notch 119 causes the interlocking rod 95 and the latch receiver 101 that are disengaged from the handle 111 to move right in the left window of the continuous window in FIG. The handle 111 is pushed by the pusher 122 of the push device 121, and the tip side protrudes from the cover 11n as shown in FIG. At this time, the backlashes of the meshing teeth of the spur gears 114 and 115 and the rack 116 are switched on both sides of the teeth.
As a result, the latch 20 and the latch receiver 101 are released. The window shoji 2 which is a natural wind ventilation window is supported by the main arm 3 and the sub arm 4 and is opened to the outside by its own weight. The sub-arm 4 whose lower end is pivotally attached to the collar frame 11 and the stand 11A with the pin 32b rotates outward about the pin 32b, and pulls the wire 8 coupled to the sub-arm 4. The wire 8 smoothly moves from the pulley 36 in the expected direction by the guides of the pulleys 36 and 37. At this time, even if the shoji 2 is fixed to the window frame 1 side, the shoji 2 is easily opened because the shoji 2 with the buffer stopper 15 closed is biased in the opening direction.

In the state in which the shoji 2 is opened, the shoji 2 changes its opening according to the fluctuation of the wind force applied to the shoji 2 as a natural wind ventilation window. When the opening of the shoji 2 is reduced, the wire 8 between the pulley 36 and the wire coupling member 7 is pushed and proceeds in the direction of arrow A, and the pulley 36 is rotated clockwise and the pulley 37 is rotated counterclockwise. The portion that hangs downward from the pulley 37 faces downward. Since the wire 8 is loosely inserted through the through hole 65 a of the adjustment shaft 65, the wire stopper 66 is directed downward with less resistance and is separated downward from the lower end of the adjustment shaft 65.
In order to close the shoji 2 from the state in which the shoji 2 is opened as shown in FIG. 2, the handle 111 having the tip protruding outward from the cover 11n as shown in FIG. 35 is rotated. When the handle 111 is rotated counterclockwise in FIG. 35, the spur gear 114 rotates together with the handle 111 to rotate the spur gear 115. The spur gear 115 moves the rack 116 downward. The interlock arm 131 and the interlocking rod 5 together with the rack 116 descend against the spring force of the spring 62 and pull down one end of the wire 8 coupled to the upper end of the interlocking rod 5. The other end of the wire 8 moves toward the indoor side, pulls the sub arm 4 and closes the shoji 2. At this time, the buffer stopper 15 is pushed by the flange 21 of the shoji 2 and is rotated indoors.
When the interlocking rod 5 is lowered, the wire 80 coupled to the interlocking rod 5 is pulled by the spring force of the spring 96 to keep the tension. Then, the latch receiver 101 moves leftward by the spring force of the spring 96 in FIG. Therefore, when the shoji 2 is closed, the latch 20 and the latch receiver 101 are engaged.

  When the handle 111 is returned to the original position after the shoji 2 is closed, the rack 116 is lifted through the spur gears 114 and 115. At this time, the backlash between the spur gears 114 and 115 and the rack 116 occurs on the back side in the direction in which the teeth move when the handle 111 is returned to the original position. Then, the pin 118 that rises together with the rack 116 rises in the elongated hole 5d of the interlocking rod 5, and the lower end of the elongated hole 5d is far from the lower pin 118a. The handle 111 is locked to the notch 119 lowered together with the interlocking rod 5 and the interlocking arm 131, and the handle 111 is stored in the handle accommodating hole 11r of the cover 11n.

  In the embodiment, the spring 62 is provided at the upper end position of the first interlocking rod 5, but the spring 62 may be provided at any position of the interlocking arm 131 and the first interlocking rod 5.

  The spring 96 that applies tension to the wire 80 may be provided along the horizontal frame. For example, the machine screw 86 that stops the end of the wire 80 may be pulled by the spring 96.

  In the embodiment, various types of natural wind-ventilated windows have various arms having one end pivotally attached to a shoji sash and the other end directly attached to the sash of the window frame or to a slide provided on the sash frame. Applicable to protruding windows.
