Description

  The present invention relates to a horizontal axis rotary window that can be ventilated by opening and closing a shoji by wind force.

2. Description of the Related Art Conventionally, a horizontal axis rotating window is known in which a shoji swings in accordance with a pressure difference between indoors and outdoors due to wind to perform natural ventilation. In this window, for example, as described in Patent Document 1, the shoji is pivotally supported by the vertical frame above the center in the vertical direction, and a weight is attached to the indoor side above the shoji. However, when positive pressure is applied to the window in response to the head wind, the shoji is naturally closed because the area below the pivot shaft is large.
In such a window, a cushioning device is installed on the indoor side of the lower part of the vertical frame in order to mitigate the impact of the shoji colliding with the window frame when the shoji is struck by a strong wind and closed vigorously. The cushion device described in Patent Document 1 has a cushion body pivotally supported by a horizontal axis on a base attached to a vertical frame, and the cushion body leans against the shoji when the shoji is closed. When the shoji is opened, the cushion body falls to the outdoor side. The cushion body has a built-in compression spring.When the shoji closes with a strong wind, the shock is absorbed by the compression spring, and when the shoji closes slowly, the tip of the cushion body The cushion body rises while the roller provided contacts the side of the shoji room and rotates, and the compression spring is not compressed and the cushion function does not work.

  In such a window, an arm for forcibly opening and closing the shoji is provided, but the above-mentioned cushion device always projects to the outdoor side from the position of the shoji at the time of closing when the shoji is in an open state. When closing the shoji with the arm, the cushion device may interfere with the closing of the shoji. In other words, when closing the shoji with the arm, it is necessary to move the arm slowly so that the cushion function does not work, and if the strong wind blows while the shoji is slowly closing with the arm, the cushion function will work. In some cases, the shoji bounces back, an excessive force is applied to the arm drive device or shoji, and the shoji cannot be locked normally in the closed state. Furthermore, the above cushioning device has a complicated structure and is fragile to enable the cushion function to work or not to work according to the closing moment of the shoji. And it also gets in the way of cleaning.

  SUMMARY OF THE INVENTION In view of the circumstances described above, the present invention has an object to provide a horizontal axis rotation window that generates resistance when a shoji that is closed by receiving wind is generated and does not generate resistance when the shoji is forcibly closed by an arm. To do.

In order to achieve the above object, a horizontal axis rotation window according to the first aspect of the present invention is a shoji that rotates around a horizontal axis in response to wind, and an arm that is provided on the indoor side of the shoji and controls the opening and closing of the shoji. And a shock absorber provided on the arm, the arm pivoting about a horizontal axis, the shock absorber provided below the pivot shaft of the arm , and above the pivot shaft of the arm When the shoji can be opened and closed according to the wind pressure , the arm protrudes to the position that prevents the shoji from being fully closed by receiving the shoji that rotates to the closing side under the wind. The door is evacuated indoors when the shoji is forcibly closed.

According to a second aspect of the present invention, a horizontal axis rotating window according to the invention is provided with a shoji that rotates around a horizontal axis by receiving wind, an arm that is provided on the indoor side of the shoji and that controls the opening and closing of the shoji, and is provided between the shoji and the arm. The tension elastic body is provided around the horizontal axis, and the tension elastic body is provided at a position above the pivot axis of the shoji and above the pivot axis of the arm. When the shoji is turned to the closing side in response to the wind , the tension elastic body stretches to resist the shoji that tries to close, and when the shoji is forcibly closed by the arm, the tension elastic body naturally It is characterized by shrinking to long.

  According to a third aspect of the present invention, the horizontal axis rotary window has the structure of the second aspect of the invention, wherein one end of the sub-arm is rotatably provided on one of the arm or the shoji, and the other end of the sub-arm is a tensile elastic body. The other end of the tensile elastic body is connected to the other end.

  In addition to the structure of the invention described in claim 1, 2 or 3, the horizontal axis rotation window according to the invention described in claim 4 extends over a position above the pivot axis of the shoji and above the pivot axis of the arm. Further, a tensile elastic body is further provided, and this tensile elastic body is characterized in that it is contracted to a natural length when the shoji is forcibly closed with an arm.

According to the first aspect of the present invention, the horizontal axis rotary window is provided with a buffer portion below the pivot shaft of the arm that controls opening and closing of the shoji, and the buffer portion is located indoors above the pivot shaft of the arm. rotates, in a state where shoji can be opened and closed in response to wind pressure, for receiving a sliding door which rotates the closing side before the wind shoji protrudes to a position that prevents the fully closed, the buffer unit Rutotomoni can absorb the momentum closing shoji, shoji can be prevented from closing to the fully closed position by. On the other hand, when the shoji is forcibly closed by the arm, the buffer portion is retracted to the indoor side, so that it does not resist the closing of the shoji. By providing the arm with a buffer, the structure can be simplified and stable operation can be obtained.

According to a second aspect of the present invention, the horizontal axis rotation window is provided with a tensile elastic body over a position above the pivot axis of the shoji and above the pivot axis of the arm. The tension elastic body can absorb the moment of closing the shoji by resisting the shoji that tries to close and stretch when the tension elastic body is turned to the closing side.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. 1 to 7 show a first embodiment of a horizontal axis rotation window according to the present invention. In this window, as shown in FIG. 4, a window frame 14 is constituted by an upper frame 10, a lower frame 11, left and right vertical frames 12a and 12b, and an intermediate vertical frame 13, and a left vertical frame 12a. The shoji 1 is pivotally supported by the support shaft 2 between the right vertical frame 12b and the intermediate vertical frame 13 and between the right vertical frame 12b and the intermediate vertical frame 13, respectively. The shoji 1 is composed of an upper arm 15, a lower arm 36, and left and right vertical shafts 21, 21 that are assembled into four sides, and a glass 42 is fitted therein. The support shaft 2 supports the shoji 1 in an eccentric state above the intermediate height, and the shoji 1 is provided with a weight 16 on the indoor side of the upper arm 15, and in a windless state, as shown in FIG. It is designed to stand still with 45 ° open. A shoji door opening / closing device 17 for forcibly closing or opening the shoji 1 is provided on the indoor side of the intermediate vertical frame 13.

As shown in FIGS. 1 and 4 to 6, the shoji opening / closing device 17 is provided at the both ends of the pivot shaft 4 and the pivot shaft 4 provided horizontally at substantially the same height as the support shaft 2 of the shoji 1. The left and right arms 3 and driving means 18 for driving the rotating shaft 4 are provided. As shown in FIG. 1, the arm 3 is formed in a shape bent in a “f” shape, and a rubber roller 20 is attached to an upper portion of the arm 19 that extends upward. The shoji 1 is held in a closed state by pushing the upper part 21.
A spring mounting portion 22 is formed on the upper portion of the arm 19 extending upward so as to protrude indoors. A spring connecting member 23 is provided at a position above the support shaft 2 of the vertical shaft 21. A primary spring 24 (corresponding to a tensile elastic body in claim 4) as a primary elastic body is provided across the spring mounting portion 22 and the spring connecting member 23 of the vertical rod 21. As shown in FIG. 1, the primary spring 24 has a natural length when the shoji 1 is closed and held by the arm 3, and no tensile force is generated.
A secondary rubber 5 (corresponding to a buffer portion in claim 1) as a secondary elastic body is provided at the front end of the arm 25 extending below the arm 3 toward the outdoor side. The secondary rubber 5 is located below the support shaft 2 of the shoji 1 and is located farther indoors than the shoji 1 when the shoji 1 is closed and held by the arm 3.
As the driving means 18, as shown in FIG. 5, a linear actuator in which the rod 26 is expanded and contracted by a motor, pneumatic pressure, or the like is used, and the tip of the rod 26 rotates the arm via an L-shaped connecting arm 27. It is connected to the shaft 4 and rotates the rotating shaft 4 as the rod 26 expands and contracts. The drive means 18 is provided so as to be housed in the intermediate vertical frame 13.

When the rod 26 of the driving means 18 is extended, the rotating shaft 4 and the arm 3 are rotated indoors as shown in FIG. 2, and then the secondary rubber 5 is below the support shaft 2 of the vertical shaft 21 of the shoji 1. The shoji 1 opens to push the position outward. The arm 3 stops when the arm 19 extending upward is inclined by 45 ° toward the indoor side, and the shoji 1 is stopped when the shoji 1 is opened by about 45 ° so as to follow the arm 3 (the shoji fully open state). At this time, the primary spring 24 is in a slightly extended state, and the secondary rubber 5 is positioned below the support shaft 2 of the shoji 1 and outside the shoji position 28 when closed. .
In this state, as shown in FIG. 3, when the wind W is applied toward the shoji 1, the shoji 1 tends to close because the area below the support shaft 2 is larger. Then, the primary spring 24 is extended to generate a tensile force F1 that pulls the upper part of the shoji 1 to the indoor side, and resists the shoji 1 that is to be closed. The tensile force F1 increases as the rotation angle of the shoji 1 increases. As shown in FIG. 2, the secondary rubber 5 has a gap between the shoji 1 in the fully opened state, so that the head wind W is weak and irrelevant as long as the closing angle of the shoji 1 is small, but the head wind W is strong to some extent. When the shoji 1 is closed more than a certain angle, as shown in FIG. 3, the shoji 1 is pressed against the collar 21 of the shoji 1 and compressed, and the repulsive force F2 resists the shoji 1 to be closed. Stops closing. The repulsive force F2 increases as the rotation angle of the shoji 1 increases. Further, the secondary rubber 5 also has a function of a cushion that softens the impact of the shoji 1 colliding with the vertical frames 12a, 12b, 13 when the shoji 1 closes vigorously by being blown by the strong head wind W.

FIG. 12 is a graph showing the result of measuring the flow rate of wind taken into the room when the pressure difference inside and outside the room is changed between 0 and 250 Pa in the horizontal axis rotation window described above. As shown in the graph, it can be seen that in the horizontal axis rotary window, a wind having a substantially constant flow rate can be taken into the room in the pressure difference range of 50 to 250 Pa. This is because the primary spring 24 and the secondary rubber 5 resist the shoji 1 to be closed.
When only the primary spring 24 is provided and the secondary rubber 5 is not provided, as shown in FIG. 13, the shoji 1 is completely closed in a strong wind, and the wind cannot be taken into the room. When the primary spring 24 is not provided, the shoji 1 is completely closed even by a weaker wind.
The horizontal axis rotation window of this embodiment is provided with a primary spring 24 between the arm 3 and the shoji 1, and further provided with a secondary rubber 5 at the lower part of the arm, so that the shoji 1 can be opened according to the strength of the wind W. By adjusting the degree, it can function as a constant air volume air supply window that allows a constant air volume to be taken into the room. In general, when the wind gets stronger, the shoji is forcibly closed and switched to mechanical air conditioning, but this horizontal axis rotating window can control the air supply amount regardless of the wind strength, raising the limit of the strong wind. Therefore, the use time of natural ventilation will increase, which can contribute to energy saving.

  When closing the shoji 1 with the arm 3, the rotation shaft 4 and the arm 3 are rotated outward by retracting the rod 26 of the driving means 18, and the rubber roller 20 provided at the upper end of the arm 3 is used to move the upper side of the shovel 21 to the upper side Is closed from inside the room. At this time, since the upper part of the arm 3 moves in a direction approaching the shoji 1, the primary spring 24 contracts to the natural length, while the lower part of the arm 3 moves in a direction away from the shoji, so that the secondary rubber is shown in FIG. 5 evacuates indoors rather than the shoji 1. Therefore, neither the primary spring 24 nor the secondary rubber 5 resists the shoji 1 to be closed.

  A damper device 29 is provided between the vertical frames 12a and 12b and the vertical rod 21 of the shoji 1. As shown in FIG. 7, the damper device 29 has a disk damper 30 attached to the vertical frames 12 a and 12 b, a shaft 30 a of the disk damper 30 and a lower part of the vertical rod 21 are connected by a stay 31, Resistance. This damper device 29 prevents chattering caused by connecting the primary spring 24 to the shoji, suppresses the sudden opening / closing operation of the shoji 1, and supports the realization of a constant air volume.

  The lower frame 11 is provided with a lock device 32 that locks the shoji 1 in the closed state. As shown in FIGS. 1 and 4, the locking device 32 extends and contracts the rod 33 a of the linear actuator 33 that is placed horizontally, so that the slide member 34 provided on the upper surface of the lower frame 11 extends along the longitudinal direction of the lower frame 11. The pin 35 that is slid and projects from the slide member 34 is engaged with and disengaged from a hook 37 provided on the lower arm 36 of the shoji 1. As described above, when the shoji 1 is closed by the arm 3, the secondary rubber 5 is retracted to the indoor side of the shoji 1 and does not resist the shoji 1 to be closed, so that the lock is not required. There is no.

  FIGS. 8-11 has shown 2nd Embodiment of the horizontal axis | shaft rotation window of this invention. In this embodiment, as shown in FIGS. 8 and 11, instead of attaching the secondary rubber 5 to the lower part of the arm 3 as a secondary elastic body, the spring connecting member 38 attached to the upper arm 15 of the shoji 1 and the arm 3. A secondary spring 6 (corresponding to a tensile elastic body in claim 2) is mounted between the spring mounting portions 22 at the upper end. One end of the sub arm 39 is rotatably attached to the spring mounting portion 22, and one end of the secondary spring 6 is connected to the other end of the sub arm 39, and the secondary spring 6 is connected to a spring connecting member 38 provided on the shoji. The other end is connected. The secondary spring 6 has a natural length when the shoji 1 is closed by the arm 3, and the arm 3 is rotated downward. The primary spring 24 is connected to a position above the support shaft 2 of the vertical shaft 21 and the spring mounting portion 22 of the arm 3 as in the first embodiment. In the arm 3, the lower arm 25 extends longer than that in the first embodiment, and a rubber roller 40 is attached to the tip portion thereof.

When the shoji 1 is forcibly opened, the arm 3 is rotated in the clockwise direction in FIG. 8, and the lower shovel 21 is pushed by the lower rubber roller 40 to open the shoji 1. Thereafter, the arm 3 is rotated in a slightly reverse direction, and as shown in FIG. 9, the upper arm 19 is tilted about 45 ° to the indoor side and the lower arm 25 is substantially vertical. Stop in the 45 ° open state (the shoji fully open state). At this time, the lower rubber roller 40 is located on the indoor side from the position 28 of the shoji when closed, the primary spring 24 is slightly extended, and the secondary spring 6 has a natural length. Yes.
In this state, as shown in FIG. 10, when the wind W is applied to the shoji 1, the shoji 1 tends to close because the area below the support shaft 2 is larger. Then, the primary spring 24 is extended to generate a tensile force F1 that pulls the upper part of the shoji 1 to the indoor side, and resists the shoji 1 that is to be closed. Since the secondary spring 6 has the sub arm 39 interposed at the end on the arm 3 side, the counter wind 39 is not stretched and rotated while the head wind W is weak and the closing angle of the shoji 1 is small. When the shoji 1 is strengthened and closes at a certain angle or more and the secondary spring 6 and the sub arm 39 are in a straight line, the shoji 1 is stretched to generate a tensile force F2 that pulls the upper portion of the shoji 1 indoors. That is, the secondary spring 6 does not resist the shoji 1 that closes when the wind W is weak, but resists the shoji 1 that tries to close together with the primary spring 24 when the wind W becomes strong. The same function as the secondary rubber 5 in one embodiment is exhibited.

Similarly to the first embodiment, the second embodiment described above adjusts the opening of the shoji according to the strength of the wind, and functions as a constant air supply window that allows a constant air flow to be taken into the room. be able to.
When the shoji 1 is forcibly closed by the arm 3, the upper part of the arm 3 moves in a direction approaching the shoji 1, so that both the primary spring 24 and the secondary spring 6 are contracted to the natural length. The next spring 6 does not resist the shoji 1 that is to be closed.

  A plurality of mounting holes 41 are provided in the sub arm 39 along the longitudinal direction, and the timing at which the secondary spring 6 begins to extend is adjusted by changing the mounting hole to the arm 3 or the mounting hole of the secondary spring 6. it can. The sub arm 39 can be provided on the shoji 1 side instead of being provided on the arm 3 side, and can be provided on both the arm 3 side and the shoji 1 side. In addition, in order to delay the timing at which the secondary spring 6 starts to extend, the sub arm 39 is not used, but the attachment hole at the end of the secondary spring 6 on the shoji 1 side or the arm 3 side can be formed in a long hole shape. .

  The present invention is not limited to the embodiments described above. The shoji 1 is not limited to the case in which the glass 42 is fitted in a four-sided frame as in the embodiment, but may be a box-shaped panel formed of, for example, a metal plate. Further, the present invention can also be applied to a case in which the shoji 1 is axially supported in an eccentric state below the intermediate height. The shape, mounting position, driving means, and the like of the arm 3 can be changed as appropriate. The horizontal axis rotation window of the present invention does not necessarily function as a constant air volume supply window, and the primary and secondary springs 6 and 24 are not provided between the shoji 1 and the arm 3, and the 2 What provided the next rubber 5 and what provided only one spring between the shoji 1 and the arm 3 may be used.
