Description

  The present invention relates to a mechanism for automatically controlling opening and closing of a continuous window.

  Conventionally, in various buildings, high windows for ventilation in rooms with high ceilings, and lighting provided on the roof of rooms where windows cannot be installed on the walls, so-called high lights as top lights, etc. are not directly reachable. Some of the windows have a configuration that can remotely open and close the windows. Recently, it is equipped with a drive control mechanism that automatically opens and closes the continuous window by detecting the outdoor and indoor environmental conditions such as weather and temperature changes such as wind and rain, etc., and also linked with the open / close drive control of the continuous window Some have a lock control mechanism that automatically locks and releases the closed window.

  For example, when a closing direction driving force is sequentially transmitted to each window to obtain a closed window state, by providing a window closing detection means for the window that is closed last, and receiving a closing signal from the detection means, There is a configuration in which a lock control mechanism is instructed to start locking after all windows are closed, and after all windows are locked, a signal indicating a lock completion state is displayed (for example, see Patent Document 1).

Japanese Patent Laid-Open No. 9-41796

  However, in the conventional lock control mechanism as described above, even when the windows other than the window to be detected for closure are not completely closed for some reason, the locking drive by the lock control mechanism is started. Therefore, there is also a risk that there is a window that is not completely closed by the continuous window and remains unlocked without being noticed by the management user.

  If all such windows should be closed and locked, and there are actually windows that are not closed and not locked as described above, there is a security risk. Not only does this occur, for example, in an environment where strong winds are blowing, the window is blown by strong winds and forced to open beyond the mechanical strength of the control mechanism. There was also a risk that the window itself was damaged. Moreover, such a sudden accident can occur even in a normal full window open state.

  In view of the above-described problems, an object of the present invention is to provide a control mechanism that can open and close a window that is more reliable and safer than conventional ones. In particular, an object of the present invention is to provide a control mechanism capable of obtaining a reliable closed lock state of a continuous window. Another object of the present invention is to provide an open / close control mechanism for a continuous window that can avoid damage and breakage of the drive system and the window itself against an impact generated suddenly by a strong wind or the like.

  In order to achieve the above object, the continuous window opening / closing control mechanism according to the invention described in claim 1 is pivotally supported so that the left and right vertical shafts can rotate at the substantially middle height position between adjacent vertical windows. In the open / close control mechanism of the continuous windows in which a plurality of windows are arranged side by side, a drive mechanism that controls the rotation of each window to open and close, and the opening and closing of the windows by the drive mechanism, A lock mechanism that locks each window and releases the lock before starting the window opening drive, a sensor unit that measures a predetermined environmental situation, and a setting for opening and closing that is predetermined from the measurement information by this sensor unit A closing detection means for detecting a closing completion state of each of the plurality of windows. The control unit is in a closed window operation When the detection signal of closing completion of all windows cannot be obtained from the closing detection means, a temporary opening operation is commanded to cause the locking mechanism to unlock, and the drive mechanism rotates all windows in the opening direction. Then, the redo operation of restarting the closing operation is repeated.

  Further, the continuous window opening / closing control mechanism according to the invention described in claim 2 is the continuous window opening / closing control mechanism according to claim 1, wherein the closing detection means is a proximity installed for each corresponding window frame of each window. It is characterized by having a sensor.

  Furthermore, the continuous window opening / closing control mechanism according to the invention described in claim 3 is the continuous window opening / closing control mechanism according to claim 1 or 2, wherein the sensor section includes a wind speed sensor, a rain detection sensor, and a temperature / humidity sensor. At least one of them.

  According to a fourth aspect of the present invention, there is provided the continuous window opening / closing control mechanism according to the first aspect, wherein the window opening / closing control mechanism is in contact with a predetermined portion of the window at a predetermined opening angle position of each window. A shock-absorbing member that absorbs an impact by elastic contraction at the time of collision of the predetermined portion is provided.

  Further, the continuous window opening / closing control mechanism according to claim 5 is the open window opening / closing control mechanism according to claim 4, wherein the buffer member is at an opening angle position slightly larger than an opening angle at which the buffer member abuts against a predetermined portion of the window. The shock absorber is provided with an impact sensor that abuts against the ridge of the window when the cushion member contracts and detects an impact at the time of the collision of the ridge, and the controller detects an impact force that is equal to or greater than a preset value by the impact sensor. Command to close the window.

  According to the continuous window opening / closing control mechanism of the present invention, in the closing operation, the incomplete state of the closing lock can be confirmed, and a more reliable closing state can be obtained. There is an effect that security problems can be avoided, and safer open / close control can be performed.

  In addition, the use of a buffer member and an impact sensor can prevent accidents such as impact and breakage due to sudden strong winds when the window is opened, thereby ensuring higher safety.

  In the present invention, in the mechanism for automatically controlling the opening and closing of the continuous windows, the closing detection means for detecting the closed completion state is provided for every window of the continuous windows during the closing operation, and the completion of the closing of all the windows is detected. Until the window is opened, the window closing operation is repeated until the window is closed.Therefore, when closing and locking the window, there are some windows that have not been partially closed. Such a situation is avoided, and the window can be reliably closed.

  Therefore, an unclosed window left unattended by the user or administrator even though the continuous window has not been partially closed / locked is struck by a gust of wind, etc. Risks such as damage to yourself and of course security risks are also avoided.

  As the closing detection means in the present invention, one using a proximity sensor is simple. In order to detect the closed state of all windows, this proximity sensor may be installed for each corresponding window frame of each window.

  In addition, if any of the windows has failed due to an accident or some abnormalities and it is impossible to obtain a closed state, it will be closed from the closing detection means regardless of how many times the opening and closing operation is repeated. A completion state detection signal cannot be obtained. Therefore, the number of repetitions of the opening and closing redo operation is set to about several times in advance, and the number of repetitions is counted at the same time as the repeated opening and closing redo operation starts. If the closed state is not detected after the set number of times is counted, an abnormal signal is generated. However, it is desirable to have a configuration that encourages human inspection.

  Further, in the continuous window opening / closing control mechanism according to the present invention, the control unit detects a predetermined setting value for opening / closing from the measurement information by the sensor unit that measures a predetermined environmental situation, and based on the detection result, the drive mechanism And an opening / closing operation command to the lock mechanism.

  The environmental conditions detected by this sensor unit include the presence or absence of rain, the strength of the wind, and the indoor and outdoor temperatures and humidity. That is, when detecting the presence or absence of rain, a window closing operation is commanded when it rains, and a window opening operation is commanded when the rain stops. Also, a window closing operation is commanded when the wind becomes stronger than a certain level, and a window opening operation is commanded when the wind weakens. Also, if the room is too hot or steamy compared to the outside, a window opening operation is commanded.If the room is too cold compared to the inside, a window closing operation is commanded. The opening / closing drive can be controlled in accordance with changes in these environmental conditions so as not to be blown in and to maintain a comfortable indoor temperature and humidity.

  The configuration of the sensor unit may include at least one of a rain sensor that detects the presence or absence of rain, a wind speed sensor that measures wind intensity, an outdoor or indoor temperature / humidity sensor, and the like.

  Furthermore, if a buffer member is provided that abuts against a predetermined portion of the window at a predetermined opening angle position of each window and absorbs the impact at the time of collision of the predetermined portion by elastic contraction, the normal open state of the continuous window In this case, even if a strong wind suddenly occurs and each window is strongly lifted, the window does not open to an angle that would cause damage to the opening / closing drive system, and the window collides with the buffer member at an appropriate opening angle position. At the same time, since the shock at that time is absorbed, even if sudden strong winds occur, damage and breakage of the opening / closing drive system of each window and the window itself are prevented.

  In addition, as a site | part which such a buffer member contact | abuts, any part of a window may be sufficient, However, The structure which contact | abuts to a window ridge | strength is desirable. In addition, a window vertical frame is the easiest to attach as the fixing portion of the buffer member. In this case, it is simple and preferable in design to have a configuration in which the buffer member is in contact with a vertical rod close to the window vertical frame.

  Moreover, depending on the case, it is conceivable that a strong force is applied so that the shock can no longer be absorbed. Therefore, if the sensor is further equipped with a sensor to detect the impact, and if a certain level of impact is detected, the control unit will promptly issue a closing window command. This eliminates the possibility of damage and breakage of the drive system and the window itself.

  In this case, as the impact sensor, the shock absorbing member abuts against the window ridge when the shock absorbing member contracts at an opening angle position slightly larger than the opening angle where the buffer member abuts against a predetermined portion of the window, and detects an impact at the time of collision of the ridge If the structure is installed, the shock absorbing member absorbs the impact at the time of collision with the strongly struck window portion to some extent, and the impact at that time can be detected by the collision with the window ridge.

  Such a configuration in which the buffer member and the impact sensor are provided is particularly effective for a building in which strong wind cannot be detected by the wind speed sensor depending on the location environment or the like. In other words, for a continuous window that cannot be detected by strong winds and remains open, the shock is alleviated by the cushioning member even if it is hit by strong winds, or once it is shocked by the shock sensor even if it receives a very strong hit. Since the window closing operation is performed promptly if the detection is detected, safe opening / closing control can be performed even for a continuous window of a building where it is difficult to detect the wind speed as described above.

  It is easy to install the impact sensor for one of the windows, and control the opening and closing of the entire window based on the impact detection result of this one impact sensor. It is good also as a structure which installs with respect to each window and can detect an impact for every window. In this case, if the control unit instructs the closing operation of all windows when a strong impact is detected by at least one or a set number or more of impact sensors, a more reliable measure against strong winds can be obtained.

  Further, when the opening / closing drive mechanism is designed so that each window can be individually controlled to open / close, the window closing operation based on the detection result of the impact sensor can also be performed individually for each window.

  In addition, as a configuration of a drive mechanism and a lock mechanism that performs a rotational drive for opening and closing a window according to a command from the control unit of the present invention, a window opening and closing operation and a lock / release operation are automatically performed according to a command from the control unit. The drive mechanism and the lock mechanism that have been conventionally used for the open / close mechanism of the continuous window can be widely used as long as they are configured to proceed in conjunction with each other.

  A natural ventilation window is an example of a window in which the above-described continuous window opening / closing control mechanism according to the present invention is effective. This natural ventilation window includes, for example, a wind type that uses wind pressure applied to the outer wall of the building, which is located in a light wind or no wind condition below a predetermined value, or on the leeward side of the building. By opening the window whose atmospheric pressure is lower than the inside, the air inside is discharged to the outside by the negative pressure, and ventilation is naturally performed. In this case, exhaust from the leeward side is more efficiently promoted by closing the window located on the windward side where the wind is received and the pressure inside the building is lower than the outside.

  Even in such a wind-type natural ventilation window, according to the opening / closing control mechanism of the present invention, the window opening operation is performed on the window located on the leeward side in the light wind or no wind state based on the detection result of the wind speed sensor or the like. To open the window up to a predetermined angle, command the window closing operation to the window located on the windward side where the wind pressure is applied, can be set to the window closing state, and is in the window opening state When it is detected that the window is raining or suddenly strong winds are generated, the window closing operation can be performed promptly, and a reliable locking state is obtained in conjunction with this.

  The use of the continuous window opening / closing control mechanism of the present invention is not limited to the above-described wind-type natural ventilation window, but is effective, for example, in a gravitational method using a difference in air density due to a temperature difference between the inside and outside of the room. This is due to the fact that the interior of a building is usually hotter than the outside due to the presence of various heat sources, and because the air in the room expands and becomes lighter, the air pressure is higher than the outside of the room. By opening a window provided in the upper part of the wall, indoor air is discharged to the outside and ventilation is performed naturally. In this case, if the window provided in the lower part of the wall is also opened, the outside air equivalent to that discharged from the upper window is taken into the room.

  Even in such a gravity type natural ventilation window, according to the opening / closing control mechanism of the present invention, when a pressure difference due to a temperature difference between the indoor and the outdoor is detected by a detection means such as a temperature sensor, the window opening operation is performed. To open the window at a predetermined angle, and if it detects that it has rained or sudden strong winds have occurred, it will immediately close the window in the open state. In conjunction with this, a reliable locking state can be obtained.

  Of course, it goes without saying that the continuous window opening / closing control mechanism of the present invention is not limited to the natural ventilation window as described above, but can be widely used for various continuous windows such as other ventilation windows and lighting windows.

  As an embodiment of the present invention, an open / close control mechanism will be described below, taking as an example the case of a continuous window composed of four windows in two columns and two rows. FIG. 1 is a schematic configuration diagram of a continuous window according to the present embodiment, where (a) is a front view and (b) is a longitudinal sectional view. FIG. 2 is a schematic circuit diagram showing the open / close control mechanism of the continuous window according to the present embodiment. FIG. 3 is a flowchart showing a basic window opening / closing operation by the control unit of the present embodiment, and FIG. 4 shows an opening / closing redo operation based on the detection result from the closing detection means by the control unit.

  FIG. 5 is a longitudinal sectional view showing a drive mechanism for opening and closing a window in the present embodiment, and FIG. 6 is an explanatory view showing a lock mechanism in the present embodiment. FIG. 7 is a partial enlarged view showing a shock-absorbing member in this embodiment, and FIG.

  As shown in the front view of FIG. 1, the continuous window opening / closing control mechanism according to the present embodiment is measured from a sensor unit (not shown) that measures an external environmental condition for the continuous window 1 composed of four windows 2. The drive mechanism and the lock mechanism are actuated by a command from the control unit based on the result, and the opening and closing is automatically controlled. Further, each window lower frame is positioned at a position opposite to the lower arm 4 of each window 2. A closing detection means using the installed proximity sensor 20 is provided, and a reliable full window closing state is obtained during the closing operation.

  As the opening / closing drive mechanism used for the continuous window 1 in this embodiment, for example, as shown in FIG. 5, the weight 6 provided on the indoor side of the upper collar 5 of the window 2 and the rotation of the electric motor as the drive source. It can be configured by using a rotation mechanism of the opening and closing arm 8 that is driven by the movement transmitted.

  Each window 2 is pivotally supported between adjacent vertical window frames so that the left and right vertical gutters can rotate at almost the intermediate height position, and the weight of the weight 6 causes the upper gutter 5 to move downward in the room. It is energized by. Therefore, by this urging, in the natural state, the lower part from the shaft support part 7 of each window 2 is lifted upward on the outdoor side, and the open state of the window is obtained.

  On the other hand, the open / close arm 8 is installed on the indoor side of the vertical frame of each window, and a roller R rotatably provided at the tip of the open / close arm 8 abuts the vertical rod 3 of each window 2 on the indoor side. The window 2 can be closed by pressing the vertical shaft 3 with the roller R against the downward force of the weight 6 from the indoor side to the outdoor side above the shaft support portion 7.

  The open / close arm 8 has the other end attached to the window vertical frame at a height position close to the shaft support 7 of the window via the drive shaft 9, and the tip end side rotates as the drive shaft 9 rotates. It moves. The rotation of the drive shaft 9 is due to a rotational motion transmitted through a gear mechanism (not shown) from the longitudinal axis 10 connected to the rotation shaft of an electric motor (not shown) as a drive source.

  Accordingly, when the motor is driven by the window opening operation command from the control unit, the rotational movement in the window opening direction is transmitted, and the distal end of the opening / closing arm 8 rotates in the indoor direction. As a result, the roller R holding the vertical rod 3 of the window 2 to the outside of the room moves backward to the indoor side, and the upper part of the window 2 rotates to the indoor side by the weight of the weight 6 of the upper rod 5 along with this. Window opening starts.

  When the rotation of the opening / closing arm 8 is further advanced, the roller R at the leading end turns downward from the shaft support portion 7 of the window and comes into contact with the lower side of the vertical rod 3 of the window 2. In the window opening operation command by the control unit, the motor drive is controlled so that the rotation of the opening / closing arm 8 stops when the roller R reaches the height position of the predetermined window full opening angle, and the opening / closing drive is performed. It is assumed that the driving of the whole mechanism is stopped. Accordingly, it is assumed that the roller R stopped at the predetermined height position supports the lower portion of the window 2 at the height position, and the window opening operation is completed in the support state.

  Further, when the window closing operation is instructed from the control unit, the rotational motion transmitted by the motor drive is switched to the reverse rotation from that during the window opening operation, and the drive shaft 9 is reversely rotated via the vertical axis 10 and the gear mechanism. As a result of rotation, the tip of the opening / closing arm 8 and the roller R start to rotate backward from the support state of the lower part of the vertical shaft 3 of the window 2 to the indoor side. When the rotation of the open / close arm 8 by the drive shaft 9 is advanced, the roller R turns upward from the shaft support portion 7 of the window, and the vertical shaft 3 of the window 2 that is inclined inwardly by the weight of the weight 6. Then, while further pushing back the upper part of the vertical rod 3 to the outdoor side, the vertical rod 3 rotates until it substantially follows the vertical line. Thus, the motor drive is controlled so that the vertical hook 3 becomes almost vertical and the lower hook 4 reaches the window lower frame to stop, and the drive of the entire opening / closing drive mechanism is stopped. At this time, the window 2 is in a closed state, and the window closing operation is completed.

  On the other hand, each window 2 is also locked / released by a lock mechanism in conjunction with the opening / closing operation of the window. As the lock mechanism, for example, as shown in FIG. 6, the lock unit 14 that reciprocates along the window width direction mainly inside the housing 13 installed along the window lower frame, A rotating motion by a motor drive transmitted from the engagement portion 17 formed on the indoor side of the lower collar 4 and the orthogonal transmission mechanism 11 using a gear or the like from the vertical axis 10 extends in the horizontal direction to the housing 13. And a hexagonal horizontal shaft 12 that is transmitted to a screw shaft (not shown) that is connected to the inside.

  Here, the lock unit 14 is screwed with a screw shaft in the housing 13, and a longitudinal direction parallel to the window lower frame is formed in the housing along the screw shaft by the rotation of the screw shaft accompanying the rotation of the hexagonal shaft 12. It reciprocates a predetermined distance along the direction. The lock unit 14 includes a catch portion 15 having a hook shape extending from the upper side of the housing in the outdoor direction, and a protrusion 16 provided on the outside of the outdoor space below the housing.

  Further, the engaging portion 17 of the lower collar 4 has a catch receiver 18 having a cross-sectional closing bracket (") shape for receiving the tip hook of the catch portion 15 of the lock unit 14, and a substantially inverted U-shaped cross section for receiving the protrusion 16. A projection receiver 19 having a shape is provided.

  The lock unit 14 stays in the retracted position on one side in the longitudinal direction in the housing 13 in the window open state, and when the axial rotation of the vertical axis 10 starts with the start of the window closing operation, the orthogonal transmission mechanism 11. The rotational movement is transmitted to the hexagonal horizontal shaft 12 through the shaft, the screw shaft in the housing 13 also rotates, and the lock unit 14 moves along the screw shaft from the retracted position to the other side in the housing longitudinal direction.

  When the window closing operation further proceeds and immediately before the window 2 is closed, the lower collar 4 of the window 2 is almost in proximity to the window lower frame 5, and the lock unit 14 also starts to match the engaging portion 17 of the lower collar 4, The mutual engagement begins. That is, in FIG. 6B, the lock unit 14 moves from the upper side to the lower side of the drawing, the catch portion 15 is received by the catch receiver 18, and then the protrusion 16 is received by the protrusion receiver 19.

  In the present embodiment, the receiving area of the catch receiver 18 is widened with respect to the catch portion 15, and the start timing of the reception is set a predetermined time before the start timing of receiving the protrusion 16 into the protrusion receiver 19. Thus, even if the window 2 is rolled and urged in the opening direction immediately before the engagement state between the protrusion 16 and the protrusion receiver 19 is obtained, the window is opened by the catch portion 15 and the catch receiver 18 that are already in the engagement state. Since 2 is caught, locking is surely advanced.

  Therefore, when the window 2 is in the closed state and the window closing operation is completed, the lock unit 14 is in an engaged state between the catch portion 15 and the catch receiver 18 as shown in the enlarged sectional view of FIG. After being pushed, the projection 16 and the projection receiver 19 reach the engaging position, and the movement along the screw shaft is also stopped. In the engaged state between the lock unit 14 and the engaging portion 17, the movement of the lower collar 4 of the window 2 in the window opening direction is restricted, and locking is completed.

  On the other hand, when the window opening operation is started, the shaft rotational movement in the direction opposite to that during the window closing operation of the vertical axis 10 is transmitted to the hexagonal horizontal shaft 12 via the orthogonal transmission mechanism 11, and the screw shaft is the reverse shaft. With this rotation, the lock unit 14 starts moving to the retracted position side. As a result, immediately after the window opening operation is started, the protrusion 16 is first disengaged from the engagement position with the protrusion receiver 19, and then the catch portion 15 is disengaged from the engagement state with the catch receiver 18. The locked state is released, and the lower arm 4 can move in the window opening direction, and the window opening operation proceeds. Thereafter, the movement of the lock unit 14 proceeds with the progress of the window opening operation, and at the end of the window opening operation, the lock unit 14 reaches the retracted position and stops moving.

  As described above, the opening / closing operation by the drive mechanism of the window 2 and the locking / releasing operation by the lock mechanism can be interlocked by the vertical axis 10 and the hexagonal horizontal axis 12 that are connected to each other. In addition, in the continuous window in which the plurality of windows 2 are arranged in parallel, the drive mechanism installed for each window 2, the adjacent vertical axes 10 of the lock mechanism, and the hexagonal horizontal axes 12 are connected to drive the motor. It is sufficient to adopt a configuration that sequentially transmits the rotational motion due to.

  Further, in the continuous window opening / closing control mechanism according to the present embodiment, the control unit that commands the opening / closing operation as described above is obtained from an external sensor unit that measures a predetermined environmental situation as shown in the circuit diagram of FIG. The measurement information is detected on the control panel by a predetermined setting value for opening and closing, and based on the detection result, the electric motor (M1) of each continuous window whose control plate is the drive source of the drive mechanism and the lock mechanism. , M2, M3) for instructing an opening / closing operation.

  Sensors for judging window opening and closing include wind sensors that measure wind speed, rain sensors that measure rainfall, external temperature and humidity sensors that measure outside air temperature and humidity, and temperature and humidity at indoor reference positions. An internal temperature / humidity sensor to measure is common.

  For example, in the case of a wind sensor, if the installation value is set to an instantaneous wind speed of 10 m / s, the opening and closing control of the continuous window using measurement information from these sensors is performed when a higher instantaneous wind speed is detected. The operation is commanded to close the window and prevent damage due to strong wind intrusion or slamming impact on the window. Also, in the case of a rain sensor, the set value is set to, for example, 0.2 mm / h, and there is more rainfall than this. At the time of detection, control is performed to instruct the closing window movement s to close the window. Further, the temperature / humidity sensor can be controlled to adjust the air conditioning and the opening / closing of the window in association with the installation value of a comfortable or required temperature and humidity conditions.

  The window opening / closing control is performed, for example, in the process shown in the flowchart of FIG. 3 by the processing operation in the control panel that controls the window opening / closing operation based on the detection result from the measurement information of each sensor in which each set value is determined. Natural ventilation operation can be performed.

  According to this flow, when a measured value equal to or higher than the set value as described above is detected from any of the sensors, the control unit commands a window closing operation, and a measured value lower than the set value is predetermined. When the time is continued, the operation flow is returned to the start again, and the window opening operation command or the duration of the closed window state is determined according to the comparison result with the measurement value setting conditions from each sensor, and the automatic operation is automatically performed. Ventilation operation by open / close window control is possible.

  In addition to the above-described configuration, the continuous window opening / closing control mechanism according to the present embodiment includes a closing detection unit that detects the closed state of each of the windows, thereby reliably closing the continuous window and increasing safety. It is possible to secure sex.

  That is, as shown in FIG. 1, the proximity sensor 20 is installed as a closing detection means of each window 2 at a window lower frame position facing the lower side 4 interior side of each window 2, and as shown in FIG. 2, When the proximity state of the lower eyelid 3, that is, the closed state of the window 2 is obtained from each proximity sensor 20, a closing completion detection signal is transmitted to the control unit (control panel). It is assumed that the closing operation is completely completed when the control unit receives this closing completion detection signal from all the proximity sensors 20.

  Furthermore, when the closing completion detection signal is not sent even if one of the proximity sensors 20 is sent, the control unit may not be able to obtain the closing state and the locking is not completed among the windows 2 of the continuous window. Judgment is made and a window closing operation is instructed according to the flowchart shown in FIG. This means that if even one of the proximity sensors 20 does not detect the completion of closing, it is assumed that the closing lock of the continuous window is incomplete, and the reopening / closing operation is performed by opening the window once and closing it again. The process is repeated until a closing completion detection signal is obtained from the sensor 20.

  For example, if the window cannot be closed due to accidental dust trapped at the start of the window closing operation or being blown by the wind just before the lock is completed, it can be closed by repeating the redo operation once or twice. Complete status is obtained.

  However, if the window itself, its drive mechanism, lock mechanism, etc. breaks down or breaks due to an abnormal situation such as some accident, and it is impossible to obtain a closed completion state, the reopening / closing operation is repeated many times. Even if it repeats, the closing completion detection signal cannot be obtained from the proximity sensor 20 corresponding to the window 2 in question.

  Therefore, the number of repetitions of the redo operation is set in advance, the number of repetitions is counted simultaneously with the start of the re-opening / closing operation, and the closure completion detection signal is obtained for all the proximity sensors 20 even after the predetermined number of repetitions is counted. If not, the control unit may determine that an abnormal situation has occurred and display an abnormal signal.

  As described above, according to the continuous window opening / closing control mechanism of the present embodiment, the closing completion detecting means (proximity sensor) is provided for each window 2, and reopening / closing is repeated until the closing completion state of all windows is detected. Since it repeats the operation, the risk of being left as if the closing of the continuous window has been completed with the incomplete closing lock state is avoided, except when an abnormal situation in which the closing cannot be completed occurs, Window closing control is performed reliably.

  Further, in this embodiment, a buffer member that absorbs an impact is provided so that the window is not damaged or the like due to a sudden wind blow. Furthermore, an impact sensor that detects such a strong impact is provided, and the control unit promptly shifts to the window closing operation based on the detection result of the impact sensor, thereby preventing the window from repeatedly receiving a strong impact. It was.

  For example, as shown in FIGS. 1 and 7, the buffer member 30 has a window 2 in the vicinity of the top of a substantially side-shaped support member 31 attached in the vertical direction of the outdoor vertical frame of each window 2. It is installed so that it may be located in the open side upper side of the vertical gutter 3. The buffer member 30 uses a spring as an elastic mechanism. When the window 2 in an open state is rolled upward by a gust or the like, the buffer member 30 comes into contact with the vertical rod 3 and elastically contracts at the time of the collision. By doing so, the shock can be absorbed.

  Even when the window 2 is squeezed upward with a strong force by the buffer member 30 that absorbs an impact at the time of the collision with the vertical rod 3, the window 2 such as a drive mechanism or a lock mechanism is forcibly lifted beyond a predetermined opening angle. The risk of damage to the surrounding mechanical structure is avoided, and breakage of the window 2 itself is also prevented.

  Further, the impact sensor 40 according to the present embodiment is such that the limit switch 41 of the sensor comes into contact with the substantially central portion of the lower rod 4 when each window 2 is lifted upward so that the vertical rod 3 collides with the buffer member. Is positioned.

  Specifically, it is made of round steel that is horizontally mounted and fixed between the tops of the substantially side-shaped support members 31 installed on the vertical shaft 3 of the window 2 adjacent in the horizontal direction. By attaching to the horizontal member 32, the impact sensor 40 can be installed at a position corresponding to the contact with the lower eyelid 4 at a predetermined opening angle of the window 2. The limit switch 41 is positioned at a position where the lower rod 4 reaches when the vertical rod 3 contracts the buffer member 30 by the stroke distance L that is the maximum contraction amount.

  Therefore, in the control unit, when a shock is detected by the impact sensor 40, a setting is made to promptly close the window, and a strong collision that may not be absorbed by the buffer member 30 is repeated thereafter. You can close the windows before you can.

  As described above, by providing the buffer member 30 and the impact sensor 40, the window 2 itself and the surrounding mechanical structure are damaged or broken even when the continuous window is opened, even if it is subjected to a sudden strong wind. There is no fear, and safer open / close control can be performed.
