  In the case of the sliding window of Patent Document 1, it is necessary to increase the horizontal dimension of the sliding window by the amount of sliding movement of the slide hook in the horizontal direction, so that the locking mechanism of the sliding window cannot be reduced in size. It will be.

  The present invention has been provided for the purpose of solving such inconveniences, and it is an object of the present invention to provide a lock-out window locking device that can be downsized while the shoji can be securely locked in a fully closed posture.

  In the present invention, in order to solve such inconvenience, the shoji 4 is arranged in the window frame 3, and the upper part of the shoji 4 moves downward and the lower part of the shoji 4 moves in a direction away from the window frame 3. In the sliding window 1 in which the shoji 4 is opened in an inclined manner, the locking device 15 holds the shoji 4 in a fully closed posture, and includes a locking portion 30 provided in the shoji 4 and a lower frame 3b of the window frame 3. A slide rack 32 supported so as to be slidable in the left-right direction is attached to the horizontal base 31 attached so as to extend in the left-right direction along the axis, and is slidably supported by the horizontal base 31 and is oscillated by the slide rack 32. A hook 33 to be driven, a pressing member 39 that is supported by the horizontal base 31 so as to be slidable in the left-right direction and that pushes and moves the slide rack 32 in conjunction with the opening and closing of the shoji 4, and the slide rack 32 are provided. And the urging means 54 for urging the pressure member 39 side. When the shoji 4 is in the fully closed position, the slide rack 32 swings the hook 33 when the pressing member 39 pushes the slide rack 32. Thus, when the locking portion 30 is locked by the hook 33 and the shoji 4 is opened, the pressing member 39 is moved away from the slide rack 32 and the slide rack 32 is moved to the pressing member 39 side by the biasing means 54. The hook 33 swings away from the locking portion 30.

  Here, the fully closed posture of the shoji 4 includes a state in which the shoji 4 is slightly opened. The case where the horizontal base 31 is directly attached (fixed) to the lower frame 3b of the window frame 3 or the case where it is attached to the lower frame 3b via a member fixed to the lower frame 3b is applicable. Here, the case where the hook 33 is swingably supported on the horizontal base 31 by a shaft provided integrally with the hook 33 or the case where the hook 33 is swingably supported by a shaft provided on the horizontal base 31 is applicable. . The biasing means 54 corresponds to a torsion coil spring or a leaf spring.

  Specifically, the locking portions 30 are provided on both the left and right sides of the shoji 4, and hooks 33, 33, slide racks 32, 32, and pressing members 39, 39 are provided to correspond to the locking portions 30, respectively. 39 and 39 are respectively attached to racks 34 and 35 extending in the left-right direction along the lower frame 3b of the window frame 3, and are configured to slide in opposite directions by the racks 34 and 35 and the pinions 36 and 37. The racks 34 and 35 are arranged one above the other so that one pinion 36 meshes with one rack 34 and the other pinion 37 meshes with the other rack 35. 36 and the other pinion 37 are rotatably supported by the lateral base 31 and mesh with each other.

  Here, not only the positions of the hook 33, the slide rack 32, and the pressing member 39 are matched in correspondence with the position of the locking portion 30, but also the correspondence of their directions and the like is included. When the two pressing members 39, 39 are directly linked to the opening / closing of the shoji 4, and either the two pinions 36, 37 or the two slide racks 32, 32 are linked to the opening / closing of the shoji 4 The case where the members 39 and 39 are interlocked with the opening and closing of the shoji 4 is included.

  The pressing member 39 slides in the left-right direction in conjunction with the opening / closing operation device 12 for opening / closing the swivel window 1 and approaches the slide rack 32 as the shoji 4 is closed. The opening / closing operation device 12 here corresponds to a handle box that winds a wire with a manual handle or a motor, or a device that winds a wire using an actuator such as a pneumatic motor.

  In the present invention, since the hook 33 is swingably supported by the horizontal base 31 attached to the lower frame 3b of the window frame 3, for example, the hook 33 is slid in the left-right direction in conjunction with opening / closing of the shoji 4 The possibility that the hook 33 rattles in the left-right direction or the like is lower than the case where the hook 33 is disposed on the member. As a result, when the shoji 4 is in the fully closed posture, the latching portion 30 can be reliably latched by the hook 33 to lock the shoji 4. In addition, the lock device 15 can be reduced in size by reducing the number of parts as much as the member that slides the hook 33 can be eliminated.

  If the latching | locking part 30, the hook 33, the slide rack 32, and the press member 39 are provided in both right and left sides, the shoji 4 can be locked more reliably. In addition, since the pinions 36 and 37 that mesh with the racks 34 and 35 are meshed with each other, the number of parts is reduced as compared with the case where one pinion 36 and the other pinion 37 are connected with a gear of another member. be able to. As a result, the locking device 15 can be reduced in size while the shoji 4 can be securely locked in the fully closed posture, and the labor of parts management and assembly can be reduced.

  When the pressing member 39 comes closer to the slide rack 56 as the shoji 4 is closed, the positional relationship between the pressing member 39 and the slide rack 56 when the shoji 4 is closed can be visually confirmed. It is possible to easily adjust the swing timing of the hook 54 with respect to the closing operation.

  An embodiment of a swivel window according to the present invention will be described with reference to the drawings. The opening window 1 is attached to an opening formed in an outer wall of a building such as an office building.

  As shown in FIG. 2, the sliding window 1 has a shoji 4 disposed in a window frame 3 framed in a square shape, and the shoji 4 has a plate glass 7 mounted in a frame 6 framed in a square shape. doing. A shoji roller 8 shown in FIG. 1 is arranged on the left and right of the upper end of the shoji 4, and slide rails extending in the vertical direction on the inner surface side of the upper end of the left and right vertical frames 3 a of the window frame 3. 9 is attached. The sliding roller 9 is engaged with the slide rail 9 so as to be movable in the vertical direction.

  As shown in FIG. 1, swinging that can swing in the vertical direction is possible over the upper part of the left and right vertical rods 6 a of the screen 6 and the middle of the window frame 3 in the vertical direction of the left and right vertical frames 3 a. The arms 11 are spanned respectively. The upper part of the shoji 4 moves downward along the slide rail 9 by its own weight, and the lower part of the shoji 4 moves away from the window frame 3 by the swing arm 11 (outside the building) The shoji 4 is opened in an inclined manner (see the states in FIGS. 3 and 4).

  A handle box (opening / closing operation device) 12 shown in FIG. 2 is provided at an appropriate place such as the inner wall of the building, and the handle box 12 is provided with a handle 12a, a ventilation button 12b, and a smoke exhaust button 12c. ing. The shoji 4 is configured to be closed by turning the handle 12a of the handle box 12.

  When the shoji 4 is closed (the state shown in FIG. 1) and the ventilation button 12b of the handle box 12 is pressed, the shoji 4 is opened to a predetermined ventilation posture (the posture shown in FIG. 3). When the shoji 4 is closed or the shoji 4 is opened to the ventilation posture, when the smoke exhaust button 12c of the handle box 12 is pressed, the shoji 4 is in a predetermined smoke taking posture (the posture shown in FIG. 4). ). The opening degree of the shoji 4 in the smoke exhausting posture (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 the natural wind in the open state in the ventilation posture or the smoke exhausting posture, the shoji 4 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 natural wind pressure and the weight of the shoji 4. The shoji 4 may be provided with a balancer (weight) for adjusting the opening. The balancer is preferably disposed on the upper surface of the upper collar 6c of the collar 6, for example.

  Opening and closing devices 13 and 13 are provided on the left and right sides of the opening window 1, respectively. As shown in FIGS. 1 and 3, each opening / closing device 13 includes a vertical base 16 attached so as to extend in the vertical direction along the inside of the building of the vertical frame 3 a of the window frame 3, and the vertical base 16. A fixed pulley 18 that is fixed to the upper end of the door and over which the first wire 17 is hung, and an inclination regulating bracket 20 that is provided so as to protrude from the upper part of the vertical rod 6a of the shoji 4 to the inside of the building. doing. The vertical base 16 is provided with a pair of guide rails 14 and 14 extending in the vertical direction. An opening / closing roller 19 is rotatably disposed on the protruding tip side (inside of the building) of the inclination regulating bracket 20. The opening / closing roller 19 is made of synthetic resin or the like.

  The opening / closing device 13 includes four guide rollers 21 that engage with the guide rails 14 and 14 of the vertical base 16, and is supported by the vertical base 16 so as to be movable up and down. And a pressing bracket 24 having four guide rollers 23 respectively engaged with the guide rails 14 and 14 of the vertical base 16 and supported so as to be movable up and down with respect to the vertical base 16. Have.

  The guide rails 14 and 14 are arranged side by side in the inside / outside direction of the building of the vertical base 16 (left and right direction in FIG. 1). 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 / closing bracket 22 can receive the lower end side (lower portion) of the opening / closing roller 19 of the inclination regulating bracket 20. One end (upper end) of a tension spring 26 (elevating drive means) is engaged with the opening / closing bracket 22, and the other end (lower end) of the tension spring 26 is engaged with the lower end portion of the vertical base 16. The opening / closing bracket 22 is urged downward by the tension spring 26. Note that a plurality of tension springs 26 may be arranged side by side in, for example, the inside and outside 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. Two guide rollers 23 are arranged on each of the upper and lower bracket portions 24a and 24b. In the pressing bracket 24, the upper bracket portion 24 a abuts on the upper end side (upper portion) of the opening / closing roller 19 of the inclination regulating bracket 20 by its own weight, and the inclination regulating bracket accompanying the opening / closing of the shoji 4 is provided. Corresponding to the raising / lowering of the 20 (opening / closing roller 19), the inclination regulating bracket 20 can be raised and lowered together with the inclination regulating bracket 20 in contact with the opening / closing roller 19.

  A contact portion 27 is provided on the inner side of the building at the lower end of the opening / closing bracket 22, and facing the contact portion 27, on the inner side of the building at the upper end of the lower bracket portion 24b of the pressing bracket 24, A contact portion 28 that can contact the contact portion 27 is provided. The contact portion 27 and the contact portion 28 are made of synthetic resin or the like.

  Then, for example, when the shoji 4 is opened by pressing the ventilation button 12b of the handle box 12, the open / close bracket 22 is lowered when the smoke exhaust button 12c of the handle box 12 is pressed. At that time, when the shoji 4 is changed in posture toward the closing direction (inside of the building) by the wind pressure of natural wind (state in FIG. 5), as shown in FIG. 27 abuts on the abutting portion 28 of the lower bracket portion 24 b of the pressing bracket 24 rising together with the inclination regulating bracket 20, and pushes down the pressing bracket 24.

  Then, the upper bracket portion 24a of the pressing bracket 24 comes into contact with the upper end side of the opening / closing roller 19 of the inclination restricting bracket 20, forcibly pushing down the inclination restricting bracket 20, and pushing the shoji 4 outward of the building, As a result, the shoji 4 is opened.

  That is, for example, even if smoke is exhausted during a fire, if the natural wind is strongly applied to the shoji 4 at that time, the shoji 4 changes its posture in the closing direction, and the shoji 4 follows the lowering of the opening / closing bracket 22. It becomes difficult to open. In that case, proper and quick smoke exhaustion is not performed. As a countermeasure, the pressing bracket 24 is forcibly pushed down as described above so that the shoji 4 is surely inclined to the smoke exhausting posture. When the inclination regulating bracket 20 is pushed down to a certain extent by the pressing bracket 24, the shoji 4 is naturally inclined to the smoke exhausting posture by its own weight.

  Further, for example, when the shoji 4 is in the fully closed posture (posture in FIG. 1), the saddle 6 of the shoji 4 strongly adheres to the water stop member 29 provided on the outside of the building of the window frame 3. Even if it is difficult to open, the shoji 4 is pushed to the outside of the building by forcibly pushing down the opening / closing roller 19 of the tilt restricting bracket 20 with the pushing bracket 24 as described above, so that the saddle 6 of the shoji 4 Is separated from the water stop member 29 of the window frame 3. Thereby, the shoji 4 can be opened reliably.

  The sliding window 1 has a lock device 15 that holds the shoji 4 in a fully closed position. The locking device 15 draws and holds (locks) the shoji 4 to an appropriate fully closed state when the shoji 4 is closed.

  As shown in FIGS. 6 and 7, the locking device 15 is provided along the locking portions 30 and 30 provided on the left and right sides of the lower arm 6 b of the shoji 4 on the inner side of the building, and the lower frame 3 b of the window frame 3. And a horizontal base 31 attached to the lower frame 3b, a pair of left and right slide racks 32, 32 supported by the horizontal base 31 so as to be slidable in the horizontal direction, and the slide rack 32. A pair of left and right hooks 33, 33 that are swing-driven by 32 and a lateral base 31 that is slidably supported in the left-right direction and that pushes and moves the slide racks 32, 32 in response to the opening and closing of the shoji 4. And a torsion coil spring (urging means) 54 for urging each slide rack 32 toward the respective pressing member 39 side.

  The locking device 15 has a first rack 34 having one pressing member 39 attached to one end (left side in FIG. 6) and the other pressing member 39 attached to one end (right side in FIG. 6). The second rack 35 has pinions 36 and 37 that mesh with the racks 34 and 35, respectively. Each rack 34 and 35 extends in the left-right direction along the lower frame 3 b of the window frame 3.

  As shown in FIG. 8, the horizontal base 31 is provided with two upper and lower guide rails 43 and 44 extending in the left-right direction along the lower frame 3 b of the window frame 3. A plurality of guide rollers 45 and 46 provided in the racks 34 and 35 are engaged with the guide rails 43 and 44, respectively. The second rack 35 is disposed above the first rack 34.

  As shown in FIGS. 8 and 9, the lower portion of the first pinion 36 is engaged with the first rack 34, and the upper portion of the second pinion 37 is engaged with the second rack 35. Further, the upper part of the first pinion 36 and the lower part of the second pinion 37 are engaged with each other. Thereby, when the first pinion 36 rotates, the second pinion 37 rotates in the opposite direction to the first pinion 36, and the second rack 35 slides in the opposite direction to the first rack 34.

  As shown in FIG. 6, a support base 38 that pivotally supports the pinions 36 and 37 is attached to the center of the horizontal base 31 in the left-right direction. That is, the pinions 36 and 37 are rotatably supported by the lateral base 31 via the support base 38. A pair of left and right drive pulleys 41 and 42 are attached to the support base 38. The left and right drive pulleys 41 and 42 hang the other end sides of the first wires 17 and 17 through direction change pulleys 40 and 40, respectively. The other end of each first wire 17 is fixed to left and right pressing members 39 and 39, respectively. In addition, you may comprise each direction change pulley 40 with a some pulley.

  Each of the locking portions 30 includes a base 30 a attached to the lower arm 6 b of the shoji 4, and a columnar lock pin 30 b provided upright on the base 30 a and locked to the hook 33. have. Each hook 33 is formed in a hook shape on the tip side (outside of the building), and the hook-like tips of the hooks 33 respectively face the center side in the left-right direction of the lower frame 3b (horizontal base 31) of the window frame 3. ing. The hook 33 is swingably supported on a substrate 49 fixed to the horizontal base 31 by a swing shaft 48 provided on the base end side (inside of the building).

  Each slide rack 32 is formed with a recess 32a for engaging a cylindrical engagement pin 51 provided on the proximal end side of the hook 33 toward the inside of the building. Swings according to the slide movement of the slide rack 32. Further, each slide rack 32 is provided with two elongated holes 52, 52 extending in the left-right direction, and two columnar supports provided upright on the substrate 49 in the elongated holes 52, 52, respectively. The pins 53 and 53 are engaged with each other, thereby guiding the movement of the slide rack 32 in the left-right direction. A torsion coil spring 54 is disposed between the slide rack 32 and the substrate 49, and each torsion coil spring 54 attaches each slide rack 32 to the lateral center of the horizontal base 31, that is, the pressing member 39 side. It is fast.

  Each of the pressing members 39 has a base 55 attached to the racks 34 and 35 and a pressing plate 56 standing on the base 55. 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 the slide rack 32 against the urging force of the torsion coil spring 54. Move to the end in the left-right direction. Along with this, the hook 33 swings to a locking posture perpendicular to the shoji 4 as shown in FIG. As a result, the hook 33 engages with the lock pin 30b of the engaging portion 30, and the shoji 4 is drawn and locked in the fully closed position (state shown in FIG. 6).

  When the shoji 4 is opened from the fully closed position, the pressing member 39 moves away 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 tilts in an inclined posture as shown in FIG. 7, and the hook 33 is released from the lock pin 30b (the lock is released). As a result, the shoji 4 is opened.

  One pressing member 39 (on the left side in FIG. 6) has a first pulling pulley 60 and a third pulling pulley 62 on which a second wire 57 fed from the handle box 12 is hung on the base 55. Have. A second pulling pulley 61 is arranged on one substrate 49 (left side in FIG. 6), and the second wire 57 is stretched over the pulling pulleys 60, 61, and 62 in this order. The distal end of the second wire 57 is fixed to the end portion (left end in FIG. 6) of the horizontal base 31.

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

  At that time, the left and right pressing members 39 are positioned on the left and right end sides of the horizontal base 31, and the slide racks 32 are pushed to the left and right end sides of the horizontal base 31 by the pressing members 39. Thereby, each hook 33 is in the locking posture, and the locking pins 30b of the locking portions 30 of the shoji 4 in the fully closed posture are respectively locked.

  In this 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 / closing bracket 22 is pulled downward by the urging force of each tension spring 26, and each pressing member 39 is moved to the lateral base 31 (the lower frame 3 b of the window frame 3) via each first wire 17. Pulled to the center in the left-right direction.

  In this state, the second wires 57 are successively drawn out from the handle box 12 so that the racks 34 and 35 move to the center side in the left-right direction of the horizontal base 31 (lower frame 3b). The member 39 is separated from each slide rack 32. Then, each slide rack 32 moves to the center side in the left-right direction of the horizontal base 31 by the urging force of each torsion coil spring 54. Along with this, the hooks 33 are inclined, so that the locking pins 30b of the locking portions 30 of the shoji 4 by the hooks 33 are released, and the shoji 4 can be opened.

  At this time, the amount of the second wire 57 that is fed out from the handle box 12 is such that the opening / closing roller 19 of each inclination regulating bracket 20 of the shoji 4 is received by each opening / closing bracket 22 (ventilation position: position shown in FIG. 3). ), And the shoji 4 is set to have a height at which the ventilation posture is achieved. As described above, the shoji 4 in the ventilation posture swings to an opening degree corresponding to the wind pressure of the natural wind.

  For example, when the smoke exhaust button 12c of the handle box 12 is pressed while the shoji 4 is in the fully closed posture, the lock of the second wire 57 by the handle box 12 is released as in the case of the ventilation described above. Is done. Then, each slide rack 32 moves to the center side in the left-right direction of the horizontal base 31, and each hook 33 is inclined obliquely outward so that the lock pin of each locking portion 30 of the shoji 4 by each hook 33 is locked. The locking of 30b is released and the shoji 4 can be opened.

  The second wire 57 is fed out from the handle box 12 at that time when the open / close roller 19 of each of the tilt restricting brackets 20 of the shoji 4 is received by each open / close bracket 22 (smoke exhaust position: FIG. 4). Position), the shoji 4 is set to have a height at which the smoke exhausting posture is achieved.

  Further, for example, when the smoke exhaust button 12c is pressed after the ventilation button 12b of the handle box 12 is pressed, the shoji 4 at that time is moved to the closing direction side (inside the building) by the wind pressure of natural wind. Even if the posture is changed, the opening / closing bracket 22 pushes down the pressing bracket 24 rising together with the inclination regulating bracket 20, thereby forcibly opening the shoji 4.

  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, each pressing member 39 is moved to the lateral end of the lateral base 31. Moving. The first wires 17 are pulled by the pressing members 39, and the open / close brackets 22 are raised.

  As the 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 shown in FIG. 1, each pressing member 39 pushes each slide rack 32 toward the left and right ends of the horizontal base 31, thereby causing each hook 33 to swing to the above-mentioned locking position. Then, the lock pins 30b of the respective locking portions 30 are locked in a state of being drawn.

  Thus, since the hook 33 is supported by the horizontal base 31 attached to the lower frame 3b of the window frame 3, for example, the hook 33 is disposed on a member that slides in the left-right direction in conjunction with opening and closing of the shoji 4 The possibility that the hook 33 rattles in the left-right direction or the like is lower than that in the case of doing so. As a result, when the shoji 4 is in the fully closed position, the shoji 4 can be locked by reliably latching the lock pin 30b of the latching portion 30 with the hook 33.

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

  In the above description, the opening / closing devices 13 and 13 are provided on the left and right sides of the opening window 1, but the opening / closing device 13 may be provided only on either the left or right side of the opening window 1. Further, for example, the movable pulley 25 of the opening / closing bracket 22 may be omitted. In this case, one end of the first wire 17 is fixed to the opening / closing bracket 22 via the fixed pulley 18.

  In FIG. 2, the second wire 57 is led out from the lower end side of the facing window 1. However, the second wire 57 may be led out from the upper end side of the facing window 1 using, for example, a pulley. 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 and the lateral base 31 via the first pulling pulley 60.
