JP4197290B2 - Ventilation system device for horizontal axis rotation window - Google Patents

Description

    In the present invention, the horizontal axis rotation window can be manually opened and closed with an operation switch, and can be automatically opened and closed in conjunction with various detection sensors. In an emergency, both automatic and manual opening and closing can be forcibly controlled. The present invention relates to a ventilation system device that can be operated.

    The simplest method conventionally used as a ventilation method is a natural ventilation method that opens and closes windows and shoji screens to exchange room air and outside air. At first, it was opened and closed by human operation, but a horizontal axis that tried to ventilate by a natural rotating window with a balance weight protruding from the upper part of the shoji and using the hinge of the shoji as a fulcrum and wind and convection as energy. Although a rotating window (see Patent Document 1) has been provided, it is dangerous if there is no defensive means that can respond immediately to unforeseen circumstances such as gusts, blowing trees, and storms.

    Therefore, a rod is provided on the indoor side of the horizontal axis rotation window, a rotation arm is provided on the rod, and when the window is closed, the window is locked by the rotation arm by the rotation of the rod, and a shoji lock means is provided below the window to double lock. Provides technology to ensure the safety of windows. (Refer to Patent Document 1) Further, as a method of reducing the impact of hitting the window frame by closing with the momentum caused by the strong wind in the open state, a cushion device for a horizontal axis rotating window (for example, refer to Patent Documents 2 and 3), Are known.

Japanese Patent Laid-Open No. 10-102932 FIG. 1 to FIG. Japanese Patent Application Laid-Open No. 2000-8699 FIG. Japanese Patent Laid-Open No. 2002-89129 FIG. 1 to FIG.

    However, since the thing of the patent document 1 supports the rod horizontally on the indoor side of the window frame attaching part as seen in FIG. 3 of the patent document 1, there is a problem that the scenery is lost because the front of the window is crossed. is there. In addition, providing the cushioning device of Patent Document 2 or Patent Document 3 on the horizontal axis rotating window is very effective as one of the defense means that can immediately respond to unforeseen situations such as gusts, blowing of trees, and storms. If the windshield is momentarily blown by a strong wind, the lower side of the rotating window with the eccentric hinge collides with the closing direction and the cushion device is used to reduce the impact. Because it must be installed in the outdoor direction from the fully closed position and as close as possible to the shoji, the transition of the cushion device from the lying down to the leaning up is very possible in the case of an abnormal situation where the shoji collides many times. At that time, when the shoji is fully closed, it will react against the closing as much as it protrudes, increasing the load on the rod rotation motor and causing an obstacle. This time, if the cushion device is placed in a position that is as perpendicular to the shoji as much as possible and the leaning configuration at the time of closing is prioritized, the cushioning device will become the leaning configuration even in abnormal situations where the shoji collides many times. The inconvenience of not playing the role of has occurred many times. In addition, due to the recoil of the cushion when it was suddenly closed, there was an inconvenience that the upper side of the rotating window collided in the open direction.

    Further, in Patent Document 1, detection means for measuring wind speed and rainfall is provided and automatic control of opening and closing of the window is described, but detection of unforeseen situations is not only for wind speed and rainfall but also for fire and smoke. There is also a problem that they are not considered. In addition, when the inventor has experienced that the window has been closed for a long time, the sealing rubber provided between the window frame and the shoji is in close contact with the shoji, so it is easy to open it for the first time. There was a case where the rod rotation motor was damaged without opening.

    Further, as shown in FIG. 3 of the publication of Patent Document 1, the arm is attached to a rod that is horizontally and rotatably supported on the indoor side of the window frame attaching portion, and the rod is rotated by a motor so that the arm is obstructed. Although it is configured to push down vertically, in the case of multiple windows, due to the influence of installation, even if the window is actually assembled despite the production with the same standard, the entrance and exit is slightly shifted or some size There is a difference and the entrance and exit of the adjacent windows are often slightly different, and if you operate multiple arms with one rod, one window is completely closed, but another window opens There are many problems such as this, so fine adjustment of rotation is performed at the rod mounting position (base part) of the arm, but if the arm with a length of 200 mm is shifted by 1 ° at the rod mounting position, the tip is 3.5 mm. Position to. When the window is fully closed, the window is opened and closed with the naked eye, but whether it is aligned or not aligned, whether it is securely closed or open is to determine the difference within a few millimeters, with an angle of 1 ° at the root. The following adjustments are very difficult.

The present inventor has been provided for the purpose of solving such inconvenience. That is, the present invention, the horizontal axis rotation from the stile intermediate the horizontal axis times Domado was horizontally provided equilibrium weight to the indoor side upper rail portion of the sliding door which freely pivots fulcrum hinge provided at the top The window is used as a single window or a set of two windows, and is located at the same height as the hinges of this shoji, and in the indoor side, if it is a single window, it is provided in the vertical frame of the shoji vertical frame.

    First, the rotation restricting device 7 constituting the rotation restricting means of the first embodiment will be described. In FIGS. 1 to 7, the hinges 3 on both sides provided above the intermediate portion of the vertical rod 2 are freely rotated around the fulcrum. On the indoor side of the sliding window 4 on the indoor side at the same height as the hinge of the shoji 4, the two-window vertical portion 6 having the horizontal axis rotating window 1 provided with the balance weight 5 on the indoor upper side of the shoji 4. As the rotation restricting device 7 for both the horizontal axis rotation windows 1, a rotation horizontal axis 8 having a length reaching the adjacent vertical position of both windows is attached by a bearing 9, and a shoji is attached to both ends of the rotation horizontal axis 8. 4 is provided with a restricting arm 10 having a tip position adjustable structure for restricting the opening angle and the opening / closing operation of the opening 4 and as a turning means for turning the turning horizontal shaft 8, the central portion of the turning horizontal shaft 8 is provided. The rotation lever 11 protrudes from the rotation horizontal shaft 8 and the rotation lever 11 so as to rotate synchronously. Further, rollers 12 are provided at both ends of the regulation arm 10 so as to be position-adjustable and rotatable. As shown in FIG. 7, the position adjustable structure is divided into a roller attachment portion 46 and an arm main body portion 47, and the roller attachment portion 46 and the arm main body portion 47 can be rotated by a rotation shaft 48. In order to adjust the position, the fastening bolt 50 is used to adjust the position. After loosening and adjusting so that the roller 12 comes into contact with the vertical rod 2, the tightening bolt 50 may be tightened again.

    On the other hand, as shown in FIG. 3, a window opening / closing electric cylinder mounting bracket 13 is screwed in the vertical portion 6 below the bearing 9, and the window opening / closing electric cylinder mounting bracket 13 is attached to the window opening / closing electric cylinder mounting bracket 13. The bottom part is pivotally supported through a tip 15 and a disc spring 16 so as to be able to swing in the opening / closing direction of the shoji, and the shaft tip of the window opening / closing electric cylinder 14 is pivotally connected to the tip of the turning lever 11 by a connecting shaft. It is supported. The shaft of the window opening / closing electric cylinder 14 is configured such that the position can be controlled by a limit switch (not shown) at three positions of the longest (A position), middle (B position), and shortest (C position). Is operated by.

    Next, the operation of the rotation restricting device will be described. First, when the ventilation opening button of the operation switch 17 is pressed for ventilation, the shaft end of the window opening / closing electric cylinder 14 at the position A in FIG. The switch stops at the B position. Then, the shoji 4 can be rotated from the fully closed position in FIG. 4 to the position indicated by the two-dot chain line in FIG. 5, but the swinging motion is determined by the state of the wind flow and the balance weight 5. .

    This time, the fully open button of the operation switch 17 is pressed to fully open the window regardless of the movement of the wind. Then, the shaft tip of the window opening / closing electric cylinder 14 is further contracted from the B position and stopped at the C position by the limit switch. FIG. 6 shows the window position and its state at that time. The shoji 4 is pressed by the roller 12 on the other side of the restricting arm 10 and fixed without swinging in the fully opened state.

    This time, the fully closed button of the operation switch 17 is pressed to fully close the window. Then, the shaft tip of the window opening / closing electric cylinder 14 extends to the A position successively following the B position if it is in its set position, that is, the C position, and extends to the A position as it is in the B position. 10 is rotated and moved back to the state shown in FIG. 4 from the state shown in FIGS. 6 and 5 and fixed.

    The left and right slide bars 28 of the sliding window shoji are connected to each other by a connecting plate 31 via connecting brackets 30, 30, and an electric cylinder 33 parallel to the slide bar 28 is attached to an electric cylinder mounting bracket 32 attached to one lower frame. The shaft tip of the electric cylinder 33 is pivotally supported by one connecting bracket 30 and a connecting shaft. The axis of the electric cylinder 33 is configured such that the position can be controlled by a limit switch (not shown) at the longest (D position), middle (E position), and shortest (F position). it can.

    Next, the structure of the window closing device 34 constituting the window closing locking means will be described. In FIGS. 1, 10 and 11, the latching tool 26 is provided on the indoor surface side of both shoji screens. A rail 27 is attached in the longitudinal direction, a slide bar 28 is slidably provided in the rail 27, and a surface rotatable lock pin 29 for locking the locking tool 26 on the slide bar 28 is provided. Is provided.

    Next, the operation of the window closing lock device 34 will be described. When the window is fully closed, the lock pin 29 is in the D position in FIGS. When the ventilation opening button of the operation switch 17 is pressed, the electric cylinder 33 is operated, the lock pin 29 is moved from the D position to the E position and stopped, and the window is unlocked. Moves from the A position to the B position, and the lock pin 29 on the slide bar 28 moves from the E position to the F position by the B position arrival signal of the electric cylinder 14 and finally stops. When the fully open button of the operation switch 17 is pushed with the window fully closed, the electric cylinder 33 operates and the lock pin 29 moves from the D position to the E position and stops. The electric cylinder 14 is moved by the E position arrival signal. The lock pin 29 on the slide bar 28 is moved from the E position to the F position and stopped by moving from the A position to the C position and further by the C position arrival signal of the electric cylinder 14.

    When the window is fully open, the electric cylinder 33 does not move even if the ventilation open button of the operation switch 17 is pressed. However, when the fully close button of the operation switch 17 is pressed, the lock pin 29 moves from the F position to the E position. The electric cylinder 14 is moved from the C position to the A position by the E position arrival signal, and the lock pin 29 on the slide bar 28 is moved from the E position to the D position by the A position arrival signal to stop and stop. 26 will lock the window.

    Next, the configuration of the separating device 35 that constitutes the separating means for forcibly separating the close contact between the sealing rubber and the shoji will be described. In FIGS. 1, 10, and 12, the convex bracket 36 is provided on the lower shoji on the indoor side. On the other hand, an extrusion roller 38 that is rotatable on an L-shaped bracket 37 having a long hole parallel to the inclination angle of the convex bracket 36 via a height adjustment block on the slide bar 28 is configured to freely move along the long hole. Further, a spring hinge 39 that continuously pushes the pushing roller 38 to the outdoor side is provided.

    The operation of the separating device 35 will be described. When fully closed, the pushing roller 38 is in the D position in FIG. When the ventilation opening button of the operation switch 17 is pressed, the shaft tip of the electric cylinder 33 moves from the D position to the E position, the electric cylinder 14 moves from the A position to the B position by the E position arrival signal, and slides by the B position arrival signal. Since the bar 28 moves from the E position to the F position, the push roller 38 also moves to the F position. When the extruding roller 38 is in the E position, the lock pin 29 is also in the E position, and the shoji 4 has already been opened. At that time, if the shoji 4 still does not move due to close contact with the sealing rubber, when the pushing roller 38 moves from the E position to the F position, it comes into contact with the convex bracket 36 in the middle and then the convex bracket 36 is placed in the chamber. It will be pushed out and the lower arm of the shoji will be pushed out to the outside of the room, so that the close contact between the sealing rubber (not shown) and the shoji 4 will be forcibly peeled off.

    However, even when the shoji 4 is not in close contact with the sealing rubber and can sufficiently rotate, the push roller 38 moves from the E position to the F position. In the middle of this movement, the extrusion roller 38 reaches the front position of the convex bracket 36, and when the shoji 4 is struck by a gust of wind and collides suddenly, only the distance to be pushed out to the outdoor side directly collides with the extrusion roller 38 and the L-shaped bracket. 37 will be destroyed. Therefore, an elongated hole is provided in the L-shaped bracket 37, and the extrusion roller 38 is configured to be retracted along the elongated hole. If retracted, no effect will be obtained at the time of the next push-out operation, so even if retracted, the spring hinge 39 returns it to its original position. The long hole is provided in parallel to the inclination angle of the convex bracket 36 because the extrusion roller 38 is perpendicular to the convex bracket 36 when moving from the E position to the F position, and the extrusion roller 38 is difficult to retract. When moving from the position to the E position, the push-out roller 38 is unnecessary, so that it is easy to retract.

    Next, the quick-close impact mitigating device 40 constituting the quick-close impact mitigating means will be explained. In FIGS. 1 and 8 to 10, the mounting base 18 is provided on the indoor surface side of the lower part of the vertical frame of both the horizontal axis turning windows 1 and 1. Are fixedly installed, and a cushion body 19 that abuts against the vertical saddle 2 of the shoji 4 is provided on the mounting base 18 so that the horizontal axis 41 and the upper and lower limit restrictors 20 and 21 can swing within a certain angle in the vertical direction. The cushion main body 19 supports the roller part having a bracket 53 provided with a reciprocating shaft 52 that enables the rubber roller 51 to rotate and reciprocate, and the reciprocating shaft 52 of the roller part. Further, the cushion body 19 swings the roller part. And a shock absorbing cushion function by providing a compression coil spring 22 between the reciprocating shaft 52 of the roller part and the bearing of the swinging part 54. Are those which gave, usually during the reciprocating shaft 52 in a position that is most advanced, the tip of the rubber roller 51 foremost is configured to be positioned in the outdoor side of the sash fully closed position. Further, each contact portion is provided with a rubber plate 23 for preventing scratches. The upper limit restricting tool 20 regulates the upper limit of the swing so that the cushion body 19 can return to its original position by its own weight even if the swing angle of the cushion body 19 is lifted to the maximum by the combined action of the impact due to the gust or shoji collision. The lower limit restrictor 21 sets the G position in the figure. Further, the mounting base 18 is changed so that the cushion main body 19 and the shoji vertical shaft 2 come into contact with each other before the shoji 4 reaches the fully closed position so that the cushion main body 19 can be easily stored by making an angle of the cushion main body 19. A displacement lever 24 is provided, and a displacement plate 25 is provided from the slide bar 28 via a connecting bracket. The displacement lever 24 and the displacement plate 25 constitute a storage relaxation device 45 when the quick-close impact relaxation device 40 is stored.

    Next, the storage relaxation device 45 will be described. First, the structure of the displacement lever 24 will be described. As shown in FIGS. 8 and 9, the displacement lever 24 is composed of two plates 42 and 43 and one support shaft 44, and the two plates 42 and 43 are at right angles. A support shaft 44 is provided in the direction perpendicular to the plate 42 at the tip of the plate 42 opposite to the plate 43 that is fixed and attached to the attachment base 18 so as to be rotatable in the window turning direction. Thus, the lower side of the reciprocating shaft 52 of the cushion body 19 is passed. If the two plates 42 and 43 constitute an XY plane, the support shaft 44 is in a three-dimensional Z-axis direction.

    Next, the operation of the storage mitigation device and the quick-close impact mitigation device 40 will be described. In FIG. 8, when the window is open, the cushion body 19 and the plate 43 are in the G position, and the angle of the G position (the swing axis and The lower angle of the extension line of the roller shaft and the longitudinal direction of the shoji warp when fully closed is set to be a right angle or a slightly more acute angle than the right angle. Therefore, when the window is suddenly closed by a gust or the like, the vertical shaft 2 collides with the cushion body 19 and the rubber roller 51 moves backward to absorb the impact by the compression coil spring 22. In relation to the electric cylinder 33, in FIG. 10, the plate 43 constituting the displacement lever 24 is at the F position described on the displacement plate 25 and is in a stopped state. When the window closing operation is performed, the contact position between the displacement plate 25 and the plate 43 sequentially moves from the F position to the E position and then from the E position to the D position. While the plate 43 of the displacement lever 24 is in contact from the F position to the E position of the displacement plate 25 in FIG. 10, the cushion body 19 and the plate 43 are gradually displaced in the swing angle. In FIG. It will be moved to the H position. This is the end of the role of the storage relaxation device.

    When the plate 43 of the displacement lever 24 reaches the parallel portion of the displacement plate 25, the cushion body 19 maintains the H position, and the cushion body 19 is further angularly displaced only when the vertical rod 2 contacts the rubber roller 51 of the cushion body 19. Will reach the I position. As can be seen from FIG. 1, the quick-close impact mitigation device 40 has a right mounting and a left mounting. The vertical portion 6 has a line symmetrical shape, and the displacement lever 24 is also provided at the symmetrical position. However, the displacement direction of the displacement plate 25 is the same for both the left and right windows. When the cushion main body 19 is in the G position, even if the shoji 4 is urged in the closing direction due to gusts or the like, the roller part of the cushion main body 19 moves backward in the axial direction and the compression coil spring 22 acts as a cushion to alleviate the impact. When the impact force disappears, the roller part of the cushion body 19 moves forward and returns to the original position by the restoring force of the compression coil spring 22. The moment when the shoji 4 rotates in the closing direction due to wind and the like is various, so the cushion body 19 escapes not only in the axial direction but also in the swinging direction of the reciprocating shaft 52 and suddenly closes. To alleviate the impact. When it is close to the fully closed position, the pivot angle of the shoji becomes narrow, so that the impact is reduced. Therefore, even when the cushion main body 19 is in the H direction position, the impact is sufficiently mitigated. As a result of being closed, the abutment is brought into contact with the shoji vertical shaft so that the fully closed position of the shoji 4, that is, the cushion body 19 main body reaches the I position without any reaction of the compression coil spring.

    The operation of each device has been described so far. However, each of these devices does not operate separately, but all operate systematically according to a command from the electric operation control device 55. The system operation will be described by associating these separate operations. First, when the shoji 4 is in the fully closed state, the shaft tip of the opening / closing electric cylinder 14 and the rotating lever 11 are in the A position, and the locking separation mechanism is used. The shaft tip of the electric cylinder 33 is in the D position, the cushion body 19 of the sudden closing impact mitigation device is in the I position, and the restricting arm 10 is in the position of FIG.

    When the ventilation opening button of the operation switch 17 is pushed to open the ventilation of the window, the locking electric cylinder 33 is first operated to move from the D position to the E position and stop. That is, the lock pin 29 is released from the locking tool 26 and unlocked. During this time, since the slide bar 28 slides simultaneously, the contact position between the displacement plate 25 and the plate 43 also moves from the D position to the E position. Next, the electric cylinder 14 for opening and closing is operated by a signal from the limit switch at the E position, and the shaft tip of the electric cylinder 14 for opening and closing and the turning lever 11 are moved from the A position to the B position. Along with this, the cushion body 19 of the quick-close impact mitigation device moves from the I position to the H position. When the shaft tip of the electric cylinder 14 for opening and closing stops at the B position, the electric cylinder 33 is operated by a signal from the limit switch at the B position, and the shaft tip moves from the E position to the F position and stops. During this time, the extruding roller 38 extrudes the convex bracket 36, and the adhesion between the sealing rubber and the shoji 4 is peeled off. When the shaft tip of the electric cylinder 33 is moved from the E position to the F position, the contact position between the displacement plate 25 and the plate 43 is also moved from the E position to the F position. Move from the H position to the G position. Accordingly, the shoji 4 swings in a windy manner from the state shown in FIG. 5 until it comes into contact with the cushion main body 19 of the quick-close impact reducing device.

    If an abnormal gust blows during this time, the plate provided at the cushion body 19 of the sudden closing impact mitigation device at the time of sudden closing and at the bottom of the roller 12 at the tip of the regulating arm 10 and the electric cylinder 14 for opening and closing at the time of sudden opening. The impact is relieved by the spring 16.

    Next, when the fully open button of the operation switch 17 is pressed, the shaft tip of the electric cylinder 14 and the rotating lever 11 are moved from the B position to the C position, and the lower roller 12 of the regulating arm 10 is moved as shown in FIG. The shoji 4 is pressed and cannot swing, and the shoji 2 is kept fully open. When the automatic ventilation operation switch 17 is pressed to enter the automatic ventilation state, the open / close electric cylinder 14 moves from the C position to the B position and returns to the normal state.

Next, various detection sensors such as a temperature sensor, a humidity sensor, an air volume sensor, a wind speed sensor, a wind direction sensor, a rain sensor, a rain sensor, a smoke detector, a fire alarm, and the like are provided and linked to the electric operation control device 55. Explain the ventilation system for the case. Each sensor is connected to an electric operation control unit 55 in parallel as shown in FIG. 1 3, the window by a signal from each sensor performs the same operation as pressing the operation switch. There are two types of detection sensors, one that operates immediately when detected, and the other that operates when a normal range is set in advance and is out of the normal range.

    In the former case, the operation is either a fully closed operation or a fully open operation. In most cases, it will be fully closed, but for example, if you install a smoke detector both inside and outside, it will be fully closed to detect abnormal signals from the outside, and smoke will not enter inside. In order to detect the abnormal signal, the operation is to fully open and immediately discharge the smoke from the inside, and a necessary detection sensor must be selected according to the environment of use site. The fully closed operation and fully open operation are as described above.

    In the latter case, a fully automatic ventilation system is constructed, in which data within a certain period of time is accumulated to analyze the data, and the fully open, normal, and fully closed operations are automatically performed according to the result. For example, when a system device is designed by combining a temperature sensor and a wind speed sensor, when the analysis result within the set time is within the set temperature and within the set wind speed, the shaft tip of the electric cylinder 14 automatically operates by selecting the B position and is regulated. The arm 10 stops at the B position and the rotation window 1 swings as usual, and the swinging operation is determined by the state of the wind flow and the balance weight 5. Subsequently, when the analysis result within the set time indicates an abnormality, the same operation as when the fully-closed operation switch 17 is pressed and the same operation as when the fully-open operation switch 17 is pressed are performed. In some cases, it is determined by the original design settings. When the analysis result within the next set time indicates normal, the operation reverse to the previous operation is performed, and the operation of bringing the shaft tip of the electric cylinder 14 to the B position is performed. As described above, the next operation is determined by the analysis result within the set time, and thus the ventilation system apparatus constructs a fully automatic ventilation system.

    The second embodiment is different only in the form of the rotation restricting device of the first embodiment, and the other devices are the same, so the difference in form and operation will be described. The same numbers are used for those performing the same operation and action as in the first embodiment. In the rotation restricting device of the second embodiment, the drive motor is not provided in the vertical part, the direction change bevel gear box 56 is provided in the vertical part, and the motor is installed at a position away from the connecting window via the universal joint 66 and the connecting shaft 57.

As shown in FIG. 17, this motor is provided with a gear 58 on the motor rotation shaft, and a gear 59 is further meshed with the gear 58 to rotate the positioning screw shaft 60 forward and backward, and the dog 61 is meshed with the positioning screw shaft 60. The dog 61 is reciprocated in the direction of the arrow, and the three limit switches are operated by the dog 61, and the position of the fully closed (A position), ventilation open (B position), and fully open (C position) is performed by each limit switch. It is configured as follows. The configuration of the second embodiment will be described. First, in FIGS. 14, 15, and 16, a power box 62 having a function of changing the direction of deceleration and rotation is attached to the bearing mounting position of the first embodiment, and the hexagonal shaft penetrates the side surface of the power box. A rotating horizontal shaft 8 of a hexagonal axis length reaching the adjacent vertical saddle position of both windows is penetrated and fixed in the hole 63, and the opening angle and opening / closing operation of the shoji 4 are regulated at both ends of the rotating horizontal shaft 8. However, a restriction arm 10 having a structure capable of adjusting the position of the tip end portion is provided. A roller 12 made of urethane rubber is used at the tip of the restricting arm, and the restricting arm 10 is divided into a roller attachment portion 46 and an arm main body portion 47 on the tip end side, and the roller attachment portion 46 and the arm main body portion 47 have a rotation shaft 48. The shaft is fixed in advance so that it can be rotated, and an adjustment slot 49 is provided on the roller attachment 46 side, and a bolt hole (not shown) is provided on the arm body 47 side for fine adjustment movement. It is comprised so that it can be integrated by fixing both with the fastening bolt 50 after adjustment. A main body cover 64 provided in the arm main body 47 is provided with a claw notch (not shown) and an urging force accumulating device (not shown) using a lap spring plate. A stopper (not shown) with a notch is passed through the rotating horizontal shaft 8 and is connected to the arm main body so that even if a shoji is struck by strong wind, this biasing force is suddenly opened on the open side. The window is pressed by this urging force even when fully closed.

    The internal structure of the power box is such that a worm is provided on a transmission shaft to which drive is transmitted from a motor, and a worm wheel having a hexagonal shaft through hole 63 provided in the center is engaged with the worm to change the speed reduction and rotation direction. It is what. Both ends of each rotating part form a bearing structure with bearings.

    Next, the operation of the rotation restricting device according to the second embodiment will be described. In FIGS. 14 to 17, when the ventilation opening button of the operation switch 17 is pushed when fully closed, the motor passes through the universal joint 66, the connecting shaft 57, and the bevel gear box 56. When the rotation is applied to the power box 62, the lateral rotation shaft 15 rotates in the opening direction of the restriction arm 10, and the roller 12 at the tip of the restriction arm 10 in the position A in FIG. The shoji 4 is stopped and can be rotated from the fully closed position to the position indicated by the two-dot chain line, but the swinging motion is determined by the state of the wind flow and the balance weight 5.

    This time, the fully open button of the operation switch 17 is pressed to fully open the window regardless of the movement of the wind. Then, the roller 12 at the tip of the restricting arm 10 is further rotated from the B position and stopped at the C position by the limit switch, and the shoji 4 is pressed by the roller 12 at the tip of the restricting arm 10 and remains fully open. Fixed without swinging.

    This time, the fully closed button of the operation switch 17 is pushed to fully open the window. Then, the motor rotates in the reverse direction, and the roller 12 at the tip of the restricting arm 10 rotates backward to the A position sequentially after the B position if it is at the set position, that is, the C position, and reversely returns to the A position as it is at the B position. Rotate. In the restricting arm 10, the roller 12 at the tip first comes into contact with the vertical shaft 3 of the shoji 2 and is pressed thereafter, so that the shoji 2 is gradually closed around the hinge 11. Even if the shoji 2 reaches the A position when fully closed, the horizontal rotation shaft 15 further rotates, and is provided on the claw notch (not shown) provided on the restriction arm 10 and the horizontal rotation shaft 15. When it reaches the position where the notch (not shown) of the stopper just meets, the limit switch for full closing works to stop the motor, and the full closing operation by the restricting arm 10 ends. The urging force is stored by a stacked spring plate (not shown) provided inside the restricting arm 10 from the time when the shoji 2 reaches the fully closed position until the notch portions meet each other.

    Since these all operate systematically in response to commands from the electric operation control device 55, the operation will be described systematically by associating these operations. First, when the shoji 4 is in the fully closed state, the regulating arm 10 The roller 12 is in the position A in FIG. 15, the shaft tip of the electric cylinder 33 for separating the lock is in the D position, and the cushion body 19 of the quick-close impact mitigating device is in the I position.

    When the operation switch 17 for ventilation opening operation is pressed to open the window, the locking electric cylinder 33 is first operated to move from the D position to the E position and stop. That is, the lock pin 29 is released from the locking tool 26 and unlocked. During this time, the slide bar 28 slides simultaneously, so that the contact position between the displacement plate 25 and the plate 43 also moves from the D position to the E position. Next, the opening / closing motor is operated by a signal from the limit switch at the E position, and the roller 12 at the tip of the regulating arm 10 moves from the A position to the B position. Along with this, the cushion body 19 of the quick-close impact mitigation device moves from the I position to the H position. When the roller 12 at the tip of the restriction arm 10 stops at the B position, the electric cylinder 33 is operated by a signal from the limit switch at the B position, and the shaft tip moves from the E position to the F position and stops. During this time, the extruding roller 38 extrudes the convex bracket 36, and the adhesion between the sealing rubber and the shoji 4 is peeled off. When the shaft tip of the electric cylinder 33 is moved from the E position to the F position, the contact position between the displacement plate 25 and the plate 43 is also moved from the E position to the F position. Move from the H position to the G position. Accordingly, the shoji 4 swings in a windy manner from the state in which it is in contact with the roller 12 at the tip of the regulating arm 10 located at the B position until it is in contact with the cushion main body 19 of the quick-close impact mitigation device. If an abnormal gust blows during this time, the impact is alleviated by the cushion body 19 of the sudden-close impact mitigation device when it is suddenly closed, and by the urging force of the lap spring inside the restriction arm 10 when it is suddenly opened.

    Next, when the operation switch 17 for full opening operation is pressed, the roller 12 at the tip of the restricting arm 10 moves from the B position to the C position, and the roller 12 of the restricting arm 10 presses the shoji 4 so that it cannot swing, and the shoji 2 is fully opened. Will hold. When the automatic ventilation operation switch 17 is pressed to set the automatic ventilation state, the roller 12 of the restriction arm 10 moves from the C position to the B position and returns to the ventilation open state.

    Next, the above-described various detection sensors such as a temperature sensor, a humidity sensor, an air volume sensor, a wind speed sensor, a wind direction sensor, a rain sensor, a rain sensor, a smoke sensor, a fire alarm, etc. are provided and linked to the electric operation control device 55. Explain the ventilation system for the case. As shown in FIG. 12, each detection sensor is connected to the electric operation control device 55 in parallel, and the window performs the same operation as when the operation switch is pressed by a signal from each detection sensor. There are two types of detection sensors, one that operates immediately when detected, and the other that operates when a normal range is set in advance and is out of the normal range.

    In the former case, the operation is a unilateral operation of a fully closed operation or a fully open operation. In most cases, it will be fully closed, but for example, if a smoke detector is installed both inside and outside, it will be fully closed to detect abnormal signals from outside, and smoke will not enter inside. In order to detect the abnormal signal, the operation is to fully open and immediately discharge the smoke from the inside, and a necessary detection sensor must be selected according to the environment of use site. The fully closed operation and fully open operation are as described above.

    In the latter case, a fully automatic ventilation system is constructed, in which data within a certain period of time is accumulated to analyze the data, and in accordance with the result, fully open / ventilated / fully closed operations are automatically performed. For example, when a system device is designed by combining a temperature sensor and a wind speed sensor, when the analysis result within the set time is within the set temperature and within the set wind speed, the motor automatically selects the B position and operates at the tip of the restriction arm 10. The roller 12 stops at the B position and the rotating window 1 swings as usual, and the swinging motion is determined by the state of the wind flow and the balance weight 5. Subsequently, when the analysis result within the set time indicates an abnormality, the same operation as when the fully-closed operation switch 17 is pressed and the same operation as when the fully-open operation switch 17 is pressed are performed. Which is determined by the original design settings. Further, when the analysis result within the next set time indicates normal, an operation reverse to the previous operation is performed, and the operation of bringing the roller 12 of the restricting arm 10 to the B position is performed. As described above, the next operation is determined by the analysis result within the set time, and thus the ventilation system apparatus constructs a fully automatic ventilation system.

    In both Example 1 and Example 2, a fully automatic ventilation system is constructed as shown in FIG. 13, but a fully automatic ventilation system can be constructed in the same manner for three or more windows. In FIG. 13, the sensors are not directly connected to the electric operation control device 55, but the system units shown in FIG. 1 are arranged in parallel and arranged in parallel, and a relay is provided in front of them to connect each sensor to this relay. And a signal may be sent from the relay to the electric operation control device 55 of each system unit.
