Description

  The present invention relates to a horizontal axis rotary window, and more particularly, to a horizontal axis rotary window in which a shoji receives air to open and close naturally to allow ventilation.

  The present applicant has previously filed a natural ventilation window in which a shoji screen is naturally opened and closed by receiving wind to perform ventilation. This window is a type of horizontal axis rotating window, and supports the shoji in an eccentric state above the middle height of the left and right vertical frame members of the window frame, and attaches a weight to the indoor surface side of the shoji above the pivot point. On the indoor side, a shoji opening / closing device for restricting the opening / closing range of the shoji or forcibly closing or opening the shoji is provided. As shown in FIG. 13, the shoji opening / closing device is provided with a rotating shaft 82 that is rotated by a motor at substantially the same height as the support shaft 81 of the shoji 80, and an opening / closing arm 83 is attached to the rotating shaft, and is attached to the tip of the opening / closing arm. As shown in FIG. 13 (a), when the opening / closing arm 83 is held obliquely upward on the indoor side as shown in FIG. Swing in the range up to contact with the roller 84. When closing the shoji 80, as shown in FIG. 13B, the open / close arm 83 is rotated upward, and the upper side of the shoji 80 is pushed by the roller 84 of the open / close arm to close. Further, in the event of an emergency such as a fire, the open / close arm 83 is inverted to an obliquely downward state on the outdoor side, and the open state is maintained so as to support the shoji 80 from below. A cushion mechanism 85 is provided at the front end of the opening / closing arm 83 to absorb the shock when the shoji 80 is struck by a strong wind and opens to the roller 84 of the opening / closing arm (Patent Documents 1 and 2). reference.).

  A cushion device 86 is provided on the lower side of the vertical frame member of the window frame in order to absorb an impact when the shoji is blown by the wind and closes vigorously. As shown in FIG. 13, the cushion device 86 pivotally supports an arm 87 by a horizontal shaft 88 so as to be swingable, and a rod 89 is urged and held on the arm 87 by a spring 90 toward the outdoor side. As shown in FIG. 13 (a), when the shoji 80 is in a state where it opens and closes naturally, the arm 87 is in a sideways state, and the shoji 80 is struck by a strong wind. When it is attempted to close it with force, the shoji downpile collides with the roller 91 of the cushion device, and the roller 91 is pushed into the room against the spring 90, thereby absorbing the impact when the shoji is closed. On the other hand, as shown in FIG. 13B, when the shoji 80 is slowly closed by the opening / closing arm 83, the cushion device 86 is such that the arm 87 swings around the horizontal shaft 88 while the roller 84 rotates. The shock absorbing function is not exhibited (see Patent Documents 3 and 4).

Further, this type of horizontal axis rotary window is provided with a locking device for locking the shoji in a closed state. In the locking device, the locking means 92 is provided so as to be movable along the lower frame material of the window frame, and a locking tool 93 that engages with the locking means is provided on the inner side of the lower arm of the shoji. Locking / unlocking is performed by moving it with a motor or the like (see Patent Documents 1 and 2).

  When the shoji is closed by the shoji opening and closing device in the horizontal axis rotating window configured as described above, the locking means of the locking device provided on the window frame is moved to a position where it does not engage with the shoji locking device. Then, after closing the shoji with the opening and closing arm, the locking means is moved to engage with the locking tool to lock the shoji. While the shoji is closed with the opening / closing arm, the cushion device does not normally work as described above. However, when a strong wind blows while closing the shoji with the opening / closing arm, the shoji may leave the opening / closing arm and close vigorously, and the cushion device may work. Then, the shoji is pushed back by the cushion device and bounces back, and a cushion mechanism is also provided at the end of the open / close arm, so the locking device performs the locking operation without the shoji properly closed, and the lock is not locked. There was sometimes a problem.

  The present invention has been made in view of the above-described circumstances, and an object of the present invention is to enable a shoji to be securely locked by a locking device in a horizontal axis rotating window that opens and closes naturally when the shoji is subjected to wind. To do.

In order to achieve the above-mentioned object, the invention according to claim 1 is characterized in that the shoji is pivotally supported above the middle height of the left and right vertical frame members of the window frame in an eccentric state, and the indoor surface side of the shoji at the upper part from the pivot support location. A door opening / closing device provided separately from the shoji on the indoor side, a lock device that locks the shoji in the closed state , and the indoor side surface on the lower side of the shoji when the shoji is closed by the wind with a cushioning device which abuts to absorb impact, a shoji abutment cushioning device is moved to a position which does not abut the shoji the cushion releasing device that prevents work the cushioning device, the locking device shoji opening It actuates the cushion releasing device before closing the sash by a device characterized Rukoto. Cushion release tool, in order not to work the cushioning device is one which forcibly moving the sliding door abutting portion of the cushion unit.

  According to a second aspect of the present invention, the cushion release device is provided in the vicinity of the cushion device, the cam member attached to the movable portion of the lock device reciprocally moved by the driving means, and is in contact with the cam member, It is comprised with the interlocking member which moves a contact part. Here, the cam member is a member having a surface inclined with respect to the moving direction of the movable portion of the locking device, and the interlocking member is a cushion that rotates or moves up and down in contact with the cam member. This means something that conveys movement to the shoji contact part of the device. The interlocking member may be provided on the cushion device itself.

The horizontal axis rotation window according to the first aspect of the present invention drives the locking device once before closing the shoji by the shoji opening and closing device , and the cushion releasing device interlocking with the locking device makes the shoji contact portion of the cushion device the shoji. since moving to a position that does not abut to not work the cushioning device, even when the sash is closed fueled by strong winds during closing operation, without shoji it is repelled by the cushioning device, shoji-off in this state By driving the device to close the shoji, and then driving the lock device again to lock the shoji in the closed state, the shoji can be reliably locked by the locking device in the properly closed state.

  According to the second aspect of the invention, since the operation of the cushion release device is performed by the driving means of the lock device, the release operation of the cushion device and the lock operation of the shoji can be reliably performed in series, and the cushion release device Since no special driving means is required for the mechanism, the mechanism can be simplified and the cost can be reduced.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. 1 to 11 show an embodiment of a horizontal axis rotation window according to the present invention, which is a double window. As shown in FIG. 11, this window comprises a window frame 34 composed of an upper frame member 10, a lower frame member 11, left and right vertical frame members 12a and 12b, and an intermediate vertical frame member 12c. The shoji 1 is rotatably supported by the support shaft 5 between the vertical frame member 12a and the intermediate vertical frame member 12c, and between the right vertical frame member 12b and the intermediate vertical frame member 12c. The support shaft 5 supports the shoji 1 in an eccentric state above the intermediate height, and a weight 14 is attached to the indoor side of the shoji upper arm 13, and the shoji 1 is connected to the wind force and the weight 14. It opens and closes naturally due to the balance. On the indoor side of the middle vertical frame member 12c, a shoji opening / closing device 2 for restricting the opening / closing range of the shoji 1 or forcibly closing or opening the shoji is installed. The shoji opening and closing device 2 is configured as one independent unit.

  As shown in FIG. 1 and FIG. 2, the shoji opening / closing device 2 is provided with a bearing 16 opposed to a base 8 having a U-shaped cross section attached to a room side surface of an intermediate vertical frame member 12c with a bolt 15, and a rotating shaft on the bearing 16 4 is horizontally supported, and an opening / closing arm 6 is attached to both ends of the rotating shaft 4, and the opening / closing arm 6 is provided away from the shoji 1. The rotating shaft 4 is installed in parallel with the supporting shaft 5 of the shoji and at substantially the same height, and is rotated by a linear actuator 3 described later. The open / close arm 6 has a U-shape with two arms 7a and 7b opened at an angle of about 135 °, and is attached to the rotary shaft 4 perpendicularly at its refracting portion. Rubber rollers 18a and 18b that abut on the inner side surface of the vertical gutter 17 inside each shoji 1 are pivotally supported at the distal ends of the arms 7a and 7b. As shown in FIGS. 2 and 3, the structure of the attachment portion of the opening / closing arm 6 to the rotary shaft 4 is made of rubber formed by digging a square hole 20 inside a substantially cylindrical case body 19 and forming a rectangular parallelepiped shape there. The end portion 22 of the rotating shaft formed in the shape of a prism is inserted into a square hole 21 provided through the shaft mounting member 9, and the opening / closing arm 6 is attached to the case body 19 with a screw 23. The opening / closing arm 6 is pressed by a cap member 24 attached to the shaft end so that the opening / closing arm 6 and the case body 19 are not detached from the rotating shaft 4. In this way, the rubber shaft mounting member 9 is interposed between the opening / closing arm and the rotating shaft so that torque is transmitted through the rubber shaft mounting member 9, so that the shoji 1 is opened and closed suddenly by the strong wind. Even if it collides with the rubber rollers 18a, 18b of the opening / closing arm, the shaft mounting member 9 absorbs the impact of the collision, and it is possible to prevent noise and failure of the shoji opening / closing device 2 and the like. Instead of the rubber shaft mounting member 9, a metal coil spring or the like may be used.

  A driving arm 25 is fixed to the central portion of the rotating shaft 4, and a distal end portion of a rod 26 that expands and contracts the linear actuator 3 is connected to a distal end portion of the driving arm 25 by a pin 27. The end portion of the linear actuator 3 is pivotally supported on a support fitting 28 by a pin 29 so that the end of the linear actuator 3 can be swung, and the support fitting 28 is attached to the base 8 by a bolt 31 with an angle-shaped attachment fitting 30. A cushion member 32 is sandwiched between the support bracket 28 and the mounting bracket 30, and here again, the shock when the shoji 1 is struck by a strong wind and collides with the rubber roller 18 a of the open / close arm is absorbed. Further, the bolt insertion hole 33 of the mounting bracket 30 is a long hole in the vertical direction, whereby the position of the linear actuator 3 can be adjusted up and down, and the angle of the open / close arm 6 can be easily finely adjusted. The structure of the linear actuator 3 itself does not matter, but for example, a structure in which the rod 26 is expanded and contracted by rotating a screw shaft by a servo motor and moving a nut inserted through the screw shaft can be used.

  The shoji opening and closing device 2 is configured as described above. When the rod 26 of the linear actuator is extended to the maximum, as shown in FIG. 9A, the rubber roller 18a attached to the upper arm 7a of the opening and closing arm 6 is The shoji 1 is closed by coming into contact with the upper side of the support shaft 5 of the scissors 17. When the rod 26 is stopped at the intermediate position and the upper arm 7a of the open / close arm 6 is held obliquely upward as shown in FIG. 9 (b), the shoji 1 is in the rubber state of the upper arm 7a of the arm from the closed state. It swings automatically with the force of wind until it comes into contact with the roller 18a. When the rod 26 is most retracted, as shown in FIG. 9C, the lower arm 7b of the open / close arm 6 protrudes obliquely downward toward the outdoor side, and the rubber roller 18b attached to the arm is provided with a vertical shoji It contacts the lower side of the support shaft of the scissors 17 and holds the shoji 1 in an open state. Further, in the state shown in FIG. 9A, when the rod 26 of the linear actuator is contracted and the rotating shaft 4 is rotated clockwise, the rubber roller 18b attached to the lower arm 7b of the open / close arm is loaded with the shoji 17 The shoji can be rotated by abutting on the lower side, and the closed shoji can be opened. The rotation angle of the rotating shaft 4 from the state of FIG. 9A to the state of FIG. 9C is about 100 °.

  Since the shoji opening / closing device 2 is unitized, assembly at the factory is easy. Moreover, it can be assembled and adjusted in advance at the factory, and can be easily attached to the vertical frame member 12c of the window frame containing the shoji 1 from the indoor side with the bolt 15 at the construction site. Further, before the window frame is carried into the construction site, the shoji opening / closing device 2 can be attached in advance to the vertical frame member 12c of the window frame. In any case, the time required for mounting and adjusting the shoji switchgear can be greatly reduced as compared with the conventional case. Further, if the cover is attached to the base 8 to conceal the linear actuator 3 and the like, the interior design will be good.

  The lower frame member 11 is provided with a lock device 35 that locks the shoji 1 in the closed state. As shown in FIGS. 4 and 8, a rail 36 is attached to the lower frame member 11 at a lower position of the left and right shoji 1, and a slider 37 is slidably guided on the rail. The sliders 37 for the left and right shoji are connected by a connecting bar 38, and slide to the left and right as a whole by extending and contracting the rod 40 of the linear actuator 39. At the center of each slider 37, a lock pin 61 that engages with a locking tool 41 provided on the lower arm of the shoji 1 is attached, and the lock pin 61 moves to the left and right together with the slider 37 to lock the shoji 1. Unlocks automatically. Each slider 37 is provided with a cam member 43 at the end of the left and right vertical frame members 12a and 12b so that the cushion device 42 described below does not work when closing the shoji. As shown in FIG. 7, the cam member 43 has an inclined surface portion 44 that is inclined in the indoor / outdoor direction with respect to the moving direction of the slider 37, and a parallel portion 45. Further, the attachment hole 46 for attaching the cam member 43 to the slider 37 is a long hole in the left-right direction, and the attachment position of the cam member 43 can be adjusted to the left and right.

  On the lower side of the left and right vertical frame members 12a and 12b, there is provided a cushion device 42 for absorbing an impact when the shoji 1 is struck by a strong wind and closed with force. As shown in FIGS. 5, 6, and 7, the cushion device 42 swings an arm 48 around a horizontal shaft 49 parallel to the support shaft 5 of the shoji to the main body portion 47 screwed to the vertical frame members 12 a and 12 b. The rod 50 is supported on the arm 48 by the spring 51 by the spring 51 so as to be able to come in and out, and a rubber roller 52 that abuts against the shoji vertical shaft 17 is supported at the tip of the rod 50. is there. As shown in FIG. 6, when the shoji 1 is open, the arm 48 falls to the outside of the room due to the action of gravity, and the upper angle formed by the rod 50 and the longitudinal direction of the shoji 17 is 90. The arm 48 is supported by the stopper 53 so that the angle is slightly larger than °. As a result, when the shoji 1 is struck by a strong wind and closes vigorously, the shoji 1 pushes the rubber roller 52 into the room against the spring 51 to absorb the shock, and the shoji 1 is opened by the opening / closing arm 6 of the shoji opening / closing device 2. When 1 is closed slowly, the arm 48 falls to the indoor side while the rubber roller 52 is in contact with the shoji vertical shaft 17 and rotates, and the arm 48 leans diagonally against the shoji 1 without almost bending the spring 51. It becomes.

  Thus, the arm 48 normally falls naturally toward the indoor side by closing the shoji 1 with the opening / closing arm 6, but in rare cases, the shoji 1 is hit by the strong wind and collides with the rubber roller 52 during the closing operation. In some cases, the shoji 1 rebounds by the force of the spring, and the locking device 35 is activated before the shoji 1 is properly closed, and the lock is not applied. In order to prevent this, a cushion release device 54 that prevents the cushion device 42 from working when the shoji 1 is closed is provided in the horizontal axis rotation window by forcibly tilting the arm 48 of the cushion device to the indoor side. ing. The cushion release device 54 includes a cam member 43 that slides left and right on the lower frame member 11 described above, and an interlocking member 55 that is swingably provided on the cushion device 42. The interlocking member 55 is formed in a substantially L shape, and its refracting portion is pivotally supported by a pin 57 on a bracket 56 protruding from the main body portion 47. When the cam member 43 moves to the right from the state shown in FIG. 7, the lower lever 58 of the interlocking member 55 is pushed by the inclined surface portion 44 of the cam member 43 to rotate the interlocking member 55, and the other member of the interlocking member 55 is rotated. The pin 60 protruding from the lever 59 pushes up the rubber roller 52 and moves it to a position where it does not contact the shoji 1 as shown in FIG. If the shoji 1 is closed by the shoji opening and closing device 2 in this state, the cushion device 42 does not work, so the shoji 1 can be surely closed and the locking by the locking device 35 is also ensured.

  The operation procedure of the shoji opening / closing device 2 and the locking device 35 when closing the shoji 1 will be described with reference to FIG. 10. FIG. 10 (a) shows the state when the shoji 1 is opened and closed naturally. At this time, the cam member 43 is at a position away from the interlocking member 55, and the cushion device 42 is in a functioning state. When closing the shoji 1, the locking device 35 is once driven before operating the shoji opening / closing device 2, and the slider 37 is moved to the right until the lever 58 of the interlocking member 55 gets over the inclined surface 44 of the cam member 43. Let At this time, as shown in FIG. 10B, the cushion device 42 is in a state where the arm 48 does not function because the arm 48 falls to the indoor side, and the lock pin 61 is not yet engaged with the locking tool 41 of the shoji 1. In this state, the shoji opening / closing device 2 is driven, and the shoji 1 is closed by the opening / closing arm 6. Thereafter, the locking device 35 is driven again, the slider 37 is further moved to the right, and the locking pin 61 is engaged with the locking tool 41 of the shoji 1 as shown in FIG. Lock in closed state. When opening the shoji 1, the above operation is performed in reverse.

  If a large number of double window units described above are installed side by side, a multiple window can be easily configured. In this case, the shoji can be opened and closed independently for each unit of the two continuous windows. Further, when the opening / closing arm 6 of the shoji opening / closing device 2 is provided only on one side of the rotating shaft 4 and the shoji opening / closing device 2 is installed on any two of the three vertical frame members 12a, 12b, 12c, Each shoji 1 can be opened and closed independently. Moreover, if the length of the upper frame material 10 and the lower frame material 11 is lengthened and the number of the intermediate | middle vertical frame material 12c and the shoji switching device 2 is increased, the multi-span window provided with the three or more shoji 1 can be comprised.

The horizontal axis rotation window according to the present invention is not limited to the embodiment described above. The configuration of the window frame is arbitrary, and a single window with only one shoji screen may be used. Moreover, as a structure of the window frame in the case of using it as a continuous window, the vertical frame material of the window frame of the single window may be connected in a vertical manner. FIG. 12 is a cross-sectional view of the periphery of the vertical stand in this case. The window frame 34 is configured for each shoji and is fitted between the left and right vertical 62 from the indoor side, and the vertical frame members 12a and 12b are set up vertically. 62 is engaged with the engaging portion 63 from the indoor side, and the indoor side surfaces of the vertical frame members 12a and 12b are pressed by the base 8 of the shoji opening / closing device 2 attached to the indoor side surface of the vertical 62 with the bolt 15 to The materials 12 a and 12 b are prevented from being detached from the stand 62 .
