According to the present invention, the upper part of the shoji 4 disposed in the window frame 3 moves downward and the lower part of the shoji 4 moves in the direction away from the window frame 3 to open the shoji 4 in an inclined manner. And the vertical base 16 provided so as to extend in the vertical direction along the vertical frame 3a of the window frame 3, and the vertical base 16 can be moved up and down. and capable of abutting against the pressing bracket 24 to the upper portion of the regulating bracket 20, the vertical base 16 is vertically movable, opening and closing bracket 22 that are enabled receiving the lower portion of the inclined regulating bracket 20, In a state in which the inclination regulating bracket 20 pushes up the pressing bracket 24 in a state where the shoji 4 is open and the attitude of the shoji 4 can be changed to the closing direction side according to the wind pressure; There characterized by having a, and a state of opening the sliding door 4 to the flue gas posture by depressing the tilt restricting bracket 20.

As the lifting drive means here, wire rope or rope made of chemical fiber or chain is connected to the opening / closing bracket 22 and the wire rope, rope or chain is driven by motor or manual handle etc. What raises and lowers the bracket 22 and a tension spring etc. correspond. The pressing bracket 24 corresponds to one that abuts on the upper portion of the inclination regulating bracket 20 by its own weight or the like, and includes one in which the inclination pressing bracket 24 abuts on the upper portion to the inclination regulating bracket 20 by a spring. . The wind pressure here corresponds to natural wind and the like. The window frame 3 also includes a side frame and the like. The vertical base 16 corresponds to the case where it is directly attached (fixed) to the vertical frame 3a of the window frame 3, or the case where it is attached to the vertical frame 3a via a member fixed to the vertical frame 3a. More specifically, the inclination regulating bracket 20 has the roller 19 disposed on the projecting tip end side, the pressing bracket 24 abuts on the upper end side of the roller 19, and the opening / closing bracket 22 receives the lower end side of the roller 19 It is characterized by being possible.

  When the raising and lowering drive means lowers the opening and closing bracket 22 to a predetermined smoke exhaust position, the shoji 4 can tilt to a predetermined smoke exhaust position, and the opening and closing bracket 22 descends to the smoke exhaust position. When the shoji 4 is changed in posture in the closing direction by wind pressure, it can be in contact with the pressing bracket 24 to push down the pressing bracket 24.

  The window 1 here can be changed into, for example, a posture (ventilation posture) when the shoji 4 performs ventilation and a posture (smoke emission posture) when smoke is discharged at the time of fire, etc. , And the inclination angle (inclination angle with respect to the window frame 3) in the smoke exhaust posture is larger than the inclination angle of the ventilation posture. The opening and closing bracket 22 corresponds to the case where the pressing bracket 24 is continuously pressed to the smoke exhaust position and the case where the pressing bracket 24 is not pressed to the smoke exhaust position.

  The lifting drive means is connected to the opening / closing bracket 22 via a wire, and by winding the wire, the opening / closing operation device 12 for raising the opening / closing bracket 22 and the opening / closing bracket 22 are biased downward. When the winding of the wire by the opening and closing operation device 12 is released, the opening and closing bracket 22 can be lowered by the biasing force of the extension spring 26.

  The open / close operation device 12 here corresponds to a handle box for winding a wire by a manual handle 12a or a built-in motor, or a device for winding a wire using an actuator such as a pneumatic motor. Here, the case where the opening and closing operation device 12 is connected to the opening and closing bracket 22 only through the wire and the case where the opening and closing operation device 12 is connected through the pulley and other members besides the wire are included.

  In the present invention, when the opening / closing bracket 22 is moved downward by the elevation driving means, for example, the inclination regulating bracket 20 is lowered according to the lowering operation, and the shoji 4 is opened in an inclined manner. The inclination angle of the shoji 4 corresponds to the elevation position of the opening / closing bracket 22. In addition, when the opening / closing bracket 22 is raised by the raising operation by the raising / lowering driving means, the inclination regulating bracket 20 is pushed up (raised) accordingly, and the shoji 4 is closed.

  The inclination restricting bracket 20 is only received by the opening and closing bracket 22, so the opening and closing bracket 22 does not become a load when the inclination restricting bracket 20 is lifted. Accordingly, the shoji 4 can easily move in the closing direction. As a result, the shoji 4 can be properly inclined at an angle corresponding to the wind pressure.

  Moreover, when it is desired to further open the already-opened shoji 4 by the operation of the elevation driving means to a desired inclination angle, for example, the attitude of the shoji 4 may be changed to the closing direction side by wind pressure. In that case, the opening / closing bracket 22 forcibly depresses the pressing bracket 24 which is rising together with the inclination regulating bracket 20 along with the change of the posture, thereby reliably opening the shoji 4 to the desired inclination angle. Can. For example, even if the shoji 4 and the window frame 3 are in close contact with each other in the fully closed state, the shoring 4 can be reliably opened by depressing the pressing bracket 24 by the opening / closing bracket 22.

  When the pressing bracket 24 abuts on the upper end side of the roller 19 of the inclination regulating bracket 20 and the lower end side of the roller 19 can be received by the opening / closing bracket 22, the inclination regulating bracket 20 moves up and down. Even when the opening and closing bracket 22 and the pressing bracket 24 are rubbed, the friction at that time can be reduced. The opening / closing bracket 22 and the pressing bracket 24 do not become the load of raising and lowering of the inclination regulating bracket 20 by that amount, and the shoji 4 can be inclined more surely and quickly at an angle according to the wind pressure.

  Assuming that the opening / closing bracket 22 abuts on the pressing bracket 24 when it is lowered to the smoke exhaust position, the shoji 4 can be reliably opened to the opening degree necessary for smoke emission when a fire or the like occurs. It is possible to smoke properly.

  When the elevation drive means comprises the open / close operation device 12 and the tension spring 26, the means for raising / lowering the open / close bracket 22 can be simplified by that amount.

The opening degree of the shoji 4 in the smoke emission posture (the inclination angle of the shoji 4 with respect to the window frame 3) is larger than the opening degree of the shoji 4 in the ventilation posture. When the shoji 4 receives natural wind in a state of being opened in the ventilation posture or the smoke exhaust posture, the shoji swings to an opening degree corresponding to the wind pressure of the natural wind. That is, the shoji 4 swings at a balanced angle between the wind pressure of the natural wind and the weight of the shoji 4 concerned. In addition, a balancer (weight) may be attached to the shoji 4 for adjusting the opening degree. The balancer is preferably disposed, for example, on the upper surface of the upper collar 6c of the crucible 6.

A moving pulley 25 is disposed on the opening / closing bracket 22, and one end of the first wire 17 is fixed to the upper end of the vertical base 16 via the fixed pulley 18 and the moving pulley 25. The opening and closing bracket 22 can receive the lower end side (lower side portion) of the opening and closing roller 19 of the inclination regulating bracket 20. One end (upper end) of a tension spring 26 (lifting and lowering drive means) is engaged with the opening and closing bracket 22, and the other end (lower end) of the tension spring 26 is engaged with the lower end of the vertical base 16. The open / close bracket 22 is biased downward by the tension spring 26. A plurality of tension springs 26 may be arranged, for example, in the inward and outward directions of the building.

  The pressing bracket 24 is divided into upper and lower parts, and the upper bracket part 24a and the lower bracket part 24b are connected by a connecting part 24c extending in the vertical direction. The two guide rollers 23 are respectively disposed on the upper and lower bracket portions 24a and 24b. The pressing bracket 24 is configured such that the upper bracket portion 24 a abuts on the upper end side (upper portion) of the opening / closing roller 19 of the tilt regulating bracket 20 by its own weight. Corresponding to the elevation of the opening / closing roller 19, the inclination regulating bracket 20 can be raised / lowered in contact with the opening / closing roller 19 of the inclination regulation bracket 20.

  An abutting portion 27 is provided on the lower side of the lower end of the opening / closing bracket 22 so as to face the abutting portion 27 and on the upper side of the lower bracket 24b of the pressing bracket 24 on the inner side of the building, An abutting portion 28 capable of abutting on the abutting portion 27 is provided.

  That is, for example, even if it is intended to emit smoke at the time of fire, if natural wind strongly strikes the shoji 4 at that time, the shoji 4 changes its posture in the closing direction, and the shoji 4 follows the descent of the opening / closing bracket 22 It becomes difficult to open. In that case, appropriate and prompt smoke exhaustion will not be performed. As a countermeasure, as described above, the pressing bracket 24 is forcedly pushed down so that the shoji 4 is surely inclined to the smoke exhaust posture. In addition, if the inclination control bracket 20 is pushed down to a certain extent by the pressing bracket 24, then, the shoji 4 naturally inclines to the smoke exhaust posture by its own weight.

  Also, for example, when the shoji 4 is in the fully closed position (posture in FIG. 1), the weir 6 of the shoji 4 is in close contact with the water blocking member 29 provided on the building exterior side of the window frame 3. Even if it is difficult to open, as described above, by forcibly pressing the opening / closing roller 19 of the inclination regulating bracket 20 by the pressing bracket 24, the shoji 4 is pushed to the outside of the building and the weir 6 of the shoji 4 Separate from the water blocking member 29 of the window frame 3. Thereby, the shoji 4 can be opened reliably.

In addition, you may comprise each direction change pulley 40 by several pulleys.

  Each locking portion 30 has a base 30a attached to the lower rod 6b of the shoji 4 and a cylindrical lock pin 30b provided upright on the base 30a and locked to the hook 33. have. Each hook 33 is formed in a hook shape on the tip side (outer side of the building), and the hook-like tip of each hook 33 faces the center side in the left and right direction of the lower frame 3b (horizontal base 31) of the window frame 3 ing. The hook 33 is swingably supported by a base 49 fixed to the lateral base 31 by a swing shaft 48 provided on the base end side (inward side of the building).

  Each slide rack 32 is formed with a concave portion 32a for engaging a cylindrical engaging pin 51 provided on the base end side of the hook 33 toward the inside of the building, and the hook 33 is engaged by the engagement. Swings in response to the slide movement of the slide rack 32. Also, each slide rack 32 is provided with two long holes 52, 52 extending in the left-right direction, and two cylindrical supports provided upright on the substrate 49 in the long holes 52, 52. The pins 53 are engaged with each other, whereby the lateral movement of the slide rack 32 is guided. A torsion coil spring 54 is disposed between the slide rack 32 and the substrate 49, and the slide coil 32 is attached to the center side in the left-right direction of the horizontal base 31, that is, the pressing member 39 side by the torsion coil spring 54. I'm upset.

  Each pressing member 39 has a base 55 attached to the racks 34 and 35 and a pressing plate 56 erected on the base 55. Then, when the shoji 4 is in the fully closed position, the pressing plate 56 of the pressing member 39 abuts against the slide rack 32 and presses it, so that the slide rack 32 resists the biasing force of the torsion coil spring 54 and the horizontal base 31 Move to the left or right end of the Along with that, the hook 33 swings to a locking posture that is perpendicular to the shoji 4 as shown in FIG. Thereby, the hook 33 locks the lock pin 30b of the locking portion 30, and the shoji 4 is drawn and locked in the fully closed position (the state of FIG. 6).

  When the shoji 4 opens from the fully closed position, the pressing member 39 separates from the slide rack 32, and the slide rack 32 moves toward the pressing member 39 by the biasing force of the torsion coil spring 54. Then, the hook 33 swings and inclines to the inclined posture as shown in FIG. 7, and the hook 33 is released from the lock pin 30b (the lock is released). Thereby, the shoji 4 is opened.

  The first pulling pulley 60 and the third pulling pulley 62, in which the second wire 57 fed from the handle box 12 is hung on the base 55, are provided on one pressing member 39 (left side in FIG. 6). Have. The second pulling pulley 61 is disposed on one substrate 49 (the left side in FIG. 6), and the second wire 57 is stretched in the order of the pulling pulleys 60, 61, 62. The tip of the second wire 57 is fixed to the end (the left end in FIG. 6) of the lateral base 31.

  Next, the operation of the tapping window 1 of the present invention will be described. When the shoji 4 is in the fully closed position shown in FIG. 1, each opening and closing bracket 22 is pulled downward by the tension spring 26, while the handle box 12 locks the second wire 57. As a result, each opening and closing bracket 22 is held at a predetermined height position (the position shown in FIG. 1) at which the shoji 4 is in the fully closed position.

  At that time, the left and right pressing members 39 are located at the end of the horizontal base 31 in the left-right direction, and the slide racks 32 are pressed by the pressing members 39 to the end of the horizontal base 31 in the left-right direction. As a result, the hooks 33 are in the locking position, and lock the lock pins 30b of the locking portion 30 of the shoji 4 in the fully closed position.

  In that state, for example, when the ventilation button 12b of the handle box 12 is pressed, the lock of the second wire 57 by the handle box 12 is released, and the second wire 57 can be drawn out from the handle box 12. At that time, each opening and closing bracket 22 is pulled downward by the biasing force of each tension spring 26, and each pressing member 39 is made of the horizontal base 31 (lower frame 3 b of the window frame 3) via each first wire 17. It is pulled to the center side of the left and right direction respectively.

  In that state, the racks 34 and 35 move to the center side in the left and right direction of the horizontal base 31 (the lower frame 3b) by sequentially pulling out the second wire 57 from the handle box 12, and each press is performed along with the movement. The members 39 separate from the slide racks 32, respectively. Then, each slide rack 32 moves to the center side in the left and right direction of the horizontal base 31 by the biasing force of each torsion coil spring 54. Accordingly, the hooks 33 are inclined, and the locking of the lock pins 30b of the locking portions 30 of the shoji 4 by the hooks 33 is released, and the shoji 4 can be opened.

  At that time, the amount of extension of the second wire 57 from the handle box 12 is determined when each opening / closing bracket 22 receives the opening / closing roller 19 of each inclination regulating bracket 20 of the shoji 4 (ventilated position: position in FIG. 3) And the height at which the shoji 4 is in the ventilation posture. The shoji 4 in the ventilated posture swings to an opening degree according to the wind pressure of natural wind as described above.

  Also, for example, when the smoke exhausting button 12c of the handle box 12 is pressed in a state where the shoji 4 is in the fully closed position, the lock of the second wire 57 by the handle box 12 is released as in the case of the ventilation described above. Be done. Then, the slide racks 32 respectively move to the center side in the left-right direction of the horizontal base 31, and the hooks 33 are inclined outward and the lock pins of the locking portions 30 of the shoji 4 by the hooks 33 are inclined. The lock of 30b is released, and the shoji 4 can be opened.

  At this time, the amount of extension of the second wire 57 from the handle box 12 is determined when each opening / closing bracket 22 receives the opening / closing roller 19 of each inclination regulating bracket 20 of the shoji 4 (smoke exhaust position: FIG. Position), the height is set so that the shoji 4 becomes the exhaust smoke posture.

  Also, for example, when the smoke exhausting button 12c is pushed after the ventilation button 12b of the handle box 12 is pushed, the shoji 4 at that time is closed to the closing direction side (interior side of the building) by the wind pressure of natural wind. Even when the posture is changed, the opening / closing bracket 22 pushes down the pressing bracket 24 which is rising together with the inclination regulating bracket 20, whereby the shoji 4 is forcibly opened.

  When the handle 12a of the handle box 12 is turned in a state in which the shoji 4 is open, the second wire 57 is wound into the handle box 12, and accordingly, the pressing members 39 move to the end of the horizontal base 31 in the left-right direction. Moving. The respective first wires 17 are pulled by the respective pressing members 39, and the respective open / close brackets 22 are raised.

  As the respective opening / closing brackets 22 are raised, the opening / closing rollers 19 of the inclination regulating brackets 20 of the shoji 4 are pushed up to close the shoji 4. When the shoji 4 is in the fully closed position of FIG. 1, each pressing member 39 pushes each slide rack 32 to the end of the horizontal base 31 in the left-right direction, thereby swinging each hook 33 to the locking position. Then, the lock pin 30b of each locking portion 30 is locked in a state of being pulled up.

  As described above, since the inclination regulating bracket 20 is only received by the opening / closing bracket 22, the opening / closing bracket 22 does not become a load when the inclination regulation bracket 20 is lifted, and the shoji 4 is easy by that amount. Can move in the closing direction. In addition, when the smoke exhausting button 12c of the handle box 12 is pressed, the opening / closing bracket 22 pushes the pressing bracket 24 down even if the shoji 4 at that time is changed in the closing direction by natural wind pressure. Therefore, in the case of a fire or the like, the shoji 4 can be reliably opened to the opening degree necessary for smoke exhaust.

  In the above description, the other ends of the first wires 17 and 17 of the left and right opening / closing devices 13 and 13 are fixed to the left and right pressing members 39 and 39 via the drive pulleys 41 and 42, for example The other end of the first wire 17 of the opening / closing device 13 may be fixed to the pressing member 39 on the left side. That is, the other ends of the first wires 17 of the left and right opening / closing devices 13 are fixed to the left pressing member 39, respectively. In that case, the drive pulley 42 on the right side of the drive pulleys 41 and 42 can be omitted.

  In the above description, the opening and closing devices 13 and 13 are provided on the left and right sides of the swing-out window 1, respectively. However, the opening and closing device 13 may be provided on either one of the left and right sides of the swing-out window 1. Also, for example, the moving pulley 25 of the opening and closing bracket 22 may be omitted. In that case, one end of the first wire 17 is fixed to the opening / closing bracket 22 via the fixed pulley 18.

  Although the second wire 57 is led out from the lower end side of the swing-out window 1 in FIG. 2, for example, it may be configured to be pulled out from the upper end side of the swing-out window 1 using a pulley or the like. The second pulling pulley 61 and the third pulling pulley 62 may be omitted. In that case, the tip of the second wire 57 is fixed to the substrate 49 or the lateral base 31 via the first pulling pulley 60.

  The opening windows 1 may be arranged in the left-right direction and opened and closed by one handle box 12. In such a case, for example, when one pressing member 39 of each swing-out window 1 is connected by a lever or the like and one of the swing-out windows 1 is opened and closed by the handle box 12, each swing-out window 1 is simultaneously opened and closed. become.
