Description

  The present invention relates to a natural ventilation window in which a shoji can be naturally opened and closed by wind to allow ventilation.

In Patent Document 1, the upper end of the shoji is connected to the eaves frame so as to be movable up and down and rotatable, and a main arm that connects the eaves middle portion of the shoji to the lower portion of the eaves frame, and the middle of the main arm. A natural-ventilated window that has a sub-arm that connects the frame and the frame, and opens so that the shoji rolls out by its own weight when there is no wind or light wind, and closes the shoji by being pushed by wind pressure when the wind is strong It is disclosed.
In the above window, the position of the end of the main arm located at the bottom of the three connecting points to the frame of the shoji is fixed, and the position of the upper end of the shoji and the end of the sub arm is the position of the shoji. It has a structure that ascends and descends as it opens and closes, and it is difficult to increase the maximum opening angle of the shoji because these two guides must be provided adjacent to the vertical frame. .
In addition, since the tip of the main arm is connected to a position higher than the center of gravity of the shoji, this swivel window has a heavy rotation of the shoji, and the center of gravity of the shoji moves up and down as the shoji opens and closes. When opening it, it begins to lightly squeeze due to the dead weight of the shoji, but when closing it needs to raise the center of gravity, which requires a large driving force. Therefore, the reaction in the weak wind was slow.

  The present invention has been made in view of the above-described circumstances, and an object of the present invention is to provide a natural ventilation window capable of increasing the opening angle of the shoji and moving the shoji lightly.

  In order to achieve the above object, a natural ventilation window according to the first aspect of the present invention comprises a shoji, a saddle frame, a main arm and a sub arm. One end of the main arm is connected to the center of gravity of the shoji so that it can rotate freely, and the other end is connected to the upper or lower part of the collar frame so that it can move up and down and turn freely. The sub arm is characterized in that one end is rotatably connected to an intermediate part of the main arm and the other end is rotatably connected to an intermediate part of the frame.

  In the natural ventilation window according to the second aspect of the invention, in addition to the configuration of the first aspect of the invention, the sub-arm has a half length of the main arm, and one end is freely rotatable to the center in the longitudinal direction of the main arm. It is connected and the other end is rotatably connected to the collar frame at the same height position as one end of the main arm.

  The natural ventilation window according to the first aspect of the present invention is such that the position of the other end of the sub arm located in the middle is fixed, and the upper or lower part of the shoji and the main arm are connected to the three shojis provided in the frame. The other end of the door is lifted and lowered with respect to the position to open and close the door, so that the opening angle of the door can be increased. Moreover, since one end of the main arm is connected to the center of gravity position of the shoji, the shoji rotates about the position of the center of gravity, so that the movement of the shoji can be lightened.

  Further, in the natural ventilation window according to the second aspect of the present invention, the sub arm has a half length of the main arm, one end of the sub arm is pivotally connected to the longitudinal center of the main arm, and the other end is connected to one end of the main arm. Since the center of gravity of the shoji does not move up and down when opening and closing, the shoji moves lightly in both the opening and closing directions, and the response to the wind is good.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 8 is a front view of the indoor side of the window using the natural ventilation window of the present invention. This window is a building window. The window frame is constructed by framing the upper frame 11 and the lower frame 12 and the left and right frame frames 2 and 2, and an invisible mesh 13 is installed between the left and right frame frames 2 and 2. The vertical frame 14 is erected between the upper frame 11 and the mesh 13, and a glass panel 15 is fitted into the opening between the mesh 13 and the lower frame 12 to form a fitting window. A natural ventilation window that the shoji 1 opens to the outdoor side is provided in a form of a continuous window at the opening between the frame 11 and the mesh 13. A handle 16 that opens and closes the shoji 1 is provided at the bottom of the right frame 2 as viewed from the room side. In the following description, “right side” and “left side” simply mean the right side and the left side as viewed from the indoor side.

  FIG. 1 shows a state when the shoji 1 is fully opened, and FIG. 2 shows a state where the shoji 1 is closed. FIG. 3 shows a support structure for the shoji 1 to the heel frame 2. The shoji 1 is constructed by assembling an upper rod 17, a lower rod 18, and left and right rods 19, 19 on four sides, and a glass panel 20 fitted therein. As shown in FIGS. 1 and 2, a balance weight 21 is attached at a position closer to the interior side of the upper rod 17, thereby balancing the vertical and front / rear directions of the shoji 1, and the rotation shaft 5 and the center of gravity. The positions of are matched. The rotating shaft 5 is provided near the center of the shoji 1 in the vertical direction. As shown in FIGS. 3 (a) and 3 (b), a horizontal shaft 23 is provided so as to protrude laterally at the upper end of the flange 19, and a bearing 24 is attached to the tip of the horizontal shaft 23. The bearing 24 is guided by a rail 25 provided in the vertical direction on the upper surface of the inner peripheral side prospective surface of the collar frame 2 so as to be movable up and down and rotatable. One end of the main arm 3 is rotatably connected to the rotary shaft 5. A rail 26 is provided in the vertical direction at the lower part of the prospective surface on the inner peripheral side of the collar frame 2, and a slider 22 is guided and held on the rail 26 so as to be movable up and down. 27 is rotatably connected. At the center in the longitudinal direction of the main arm 3, one end of the sub-arm 4 having a half length of the main arm 3 is rotatably connected by a horizontal shaft 28, and the other end of the sub-arm 4 is expected on the inner peripheral side of the frame 2. It is rotatably connected to a horizontal shaft 29 protruding from the surface at the same height as the rotary shaft 5 of the shoji 1. FIG. 3 shows the support structure on the right side of the shoji 1, but the left side is also supported by the stand 14 or the frame 2 in the same manner.

  When there is no wind and no load is applied to the shoji 1, as shown in FIG. 1, the shoji 1 is balanced so as to stand still in an open state of 45 °. When the wind toward the shoji 1 is received, the bearing 24 attached to the upper part of the shoji 1 slides upward along the rail 25 and the slider 22 connected to the other end of the main arm 3 moves to the rail 26 as shown in FIG. Along with this, the shoji 1 rotates with the rotating shaft 5 provided at the center of gravity as a fulcrum and closes. When the wind subsides, the bearing 24 on the upper side of the shoji 1 slides downward, and the slider 22 connected to the other end of the main arm 3 slides upward, and the shoji 1 rotates with the rotating shaft 5 as a fulcrum and opens, as shown in FIG. Return to. When the shoji 1 opens and closes, the rotation shaft 5 (= center of gravity) of the shoji 1 moves horizontally as indicated by an imaginary line 30 in FIG. That is, the center of gravity of the shoji 1 does not move up and down during opening and closing.

  This point will be described with reference to the schematic diagram of FIG. The sub arm 4 is half the length of the main arm 3, one end of the sub arm 4 is connected to the center in the longitudinal direction of the main arm 3, and the other end of the sub arm 4 is attached at the same height position as one end of the main arm 3. In the initial state, ΔACD formed by the main arm 3 and the other end of the sub arm 4 is a right triangle. The position D of the other end of the sub arm 4 is fixed, and the position C of the other end of the main arm 3 is movable up and down. The main arm 3 and the sub arm 4 form two isosceles triangles (ΔABD, ΔBCD). The apex angles θ1 and θ2 of the two isosceles triangles are in a relation of θ1 + θ2 = 180 ° at an arbitrary angle, and therefore the base angles θ3 and θ4 of the isosceles triangles are always in a relation of θ3 + θ4 = 90 °. Therefore, ΔACD is always a right triangle, and it can be seen that the rotation axis 5 (one end A of the main arm) only moves horizontally.

  As described above, the natural ventilation window has the rotating shaft 5 aligned with the position of the center of gravity of the shoji 1, and the rotating shaft 5 does not move up and down during opening and closing, but only moves horizontally. The shoji 1 moves lightly in any closing direction, and the response to the wind is good. Further, the position of the other end of the sub arm 4 (horizontal axis 29) is fixed, and the upper part of the shoji 1 (horizontal axis 23) and the other end of the main arm 3 (horizontal axis 27) slide up and down relative to the position. Therefore, the opening angle of the shoji 1 can be easily set and 45 ° which can be used as a smoke exhaust window. Open up to.

FIG. 10 shows another example of the installation state of the main arm 3 and the sub arm 4. In FIG. 10A, the length of the sub arm 4 is shorter than half of the main arm 3, and the length BC of the other arm C point of the main arm 3 from the connection position B point of the sub arm 4 of the main arm 3 is the length of the sub arm 4. This is the same as the BD. In this case, the position of one end of the main arm 3 serving as the rotation shaft 5 of the shoji 1 is lower at the position A when the shoji 1 is opened than at the position A ′ when the shoji 1 is closed. Therefore, the shoji 1 can be easily opened.
10B, the length of the sub arm 4 is longer than half of the main arm 3, and the length BC of the other end C of the main arm 3 from the connection position B of the sub arm 4 of the main arm 3 is the length of the sub arm 4. This is the same as the BD. In this case, the position of one end of the main arm 3 serving as the rotating shaft 5 of the shoji 1 is lower at the position A ′ when the shoji 1 is closed than at the position A when the shoji 1 is opened. Therefore, the shoji 1 can be easily closed.
In any case, the movement of the shoji 1 can be lightened by matching the position (point A) of the rotary shaft 5 of the shoji 1 with the position of the center of gravity of the shoji 1. Further, by setting BC = BD, the direction of the force to the point C and the point D is opposite to each other, and the slide portion of the other end C point of the main arm 3 moves smoothly.

  This natural ventilation window is provided with a mechanism for opening and closing the shoji 1 and locking it when closed by operating the handle 16, and the structure thereof will be described below. As shown in FIG. 8, a vertical slide bar 31 is provided on the inner peripheral side surface of the right collar frame 2, and a slide portion 49 is provided on the upper surface of the mesh 13 so as to be slidable in the longitudinal direction. As shown in FIGS. 1 and 2, the slide portion 49 has a horizontal slide bar 32 that is slidably mounted in the longitudinal direction on the upper surface of the joint 13, and as shown in FIG. 8, an upper end portion of the vertical slide bar 31 and A right end portion of the horizontal slide bar 32 is connected by a corner drive 33 provided at a corner portion between the collar frame 2 and the mesh 13. Although the structure of the corner drive 33 will be described later, the pushing and pulling force is transmitted at a right angle. A gear 34 is connected to the shaft of the handle 16, and a rack 35 that meshes with the gear 34 is connected to the vertical slide bar 31. The handle 16 rotates downward when the shoji 1 is opened and rotates upward when the shoji 1 is closed. When the handle 16 is rotated to the closed side, the vertical slide bar 31 slides downward, and the horizontal slide bar 32 is pulled to slide to the right as indicated by the arrows in the figure.

  As shown in FIGS. 4 to 6, on the horizontal slide bar 32, a lock pin 48 that is engaged with and disengaged from a lock receiver 36 provided on the lower arm 18 of the shoji 1 is attached. A pin 37 protrudes upward at the tip of the horizontal slide bar 32, and a connecting plate 39 is provided by engaging the pin 37 with a long hole 38 in the left-right direction. The connecting plate 39 is provided with a pin stopper 40 biased by a spring 41. As shown in FIG. 6B, when the shoji 1 is in an open state, the pin 37 is positioned at the left end of the long hole 38. The pin stopper 40 is locked to the pin 37. When the side slide bar 32 is pulled to the right when the shoji 1 is closed, the release block 42 for releasing the locking of the pin stopper 40 with the pin 37 and the connecting plate 39 are connected to the blind 13. A stopper 43 for stopping at the position is provided.

As shown in FIG. 4, a corner drive 44 is provided at the corner between the invisible eye 13 and the collar frame 2. The corner drive 44 has a cylindrical guide member 44a bent into an L shape and a sliding member 44b inserted into the guide member 44a. The corner drive 44 slides in a state where the sliding member 44b is guided by the guide member 44a. By moving, the push-pull force can be transmitted at a right angle. The end of the sliding member 44b on the side of the side 13 is connected to the connecting plate 39 described above, and the shoji closing arm 45 is attached to the end of the sliding member 44b on the side of the collar frame 2. The corner drive 44 and the connecting plate 39 constitute an interlocking member 50. The shoji closing arm 45 is a substantially L-shaped vertically long bar-like member, and is installed so as to follow the inner peripheral side surface of the collar frame 2.
When the handle 16 is operated to the close side and the horizontal slide bar 32 is pulled rightward, the shoji closing arm 45 moves downward via the interlocking member 50, and as shown in FIG. Pushing down 22 closes shoji 1. Although the shoji 1 opens and closes naturally according to the wind conditions, such a shoji closing arm 45 can close the shoji 1 in any state.
As shown in FIG. 5, a lower portion of the rail 26 of the frame 2 has a biasing member 47 that biases the slider 22 upward by the force of the spring 46 when the shoji 1 is closed, and the handle 16 is opened. When the shoji closing arm 45 is moved upward, the slider 22 is pushed up by the urging member 47 to open the shoji 1.
4 to 6 show a mechanism for opening / closing and locking the left shoji 1, the right shoji 1 is configured in the same manner. The left side sliding bar 32 for the shoji 1 and the right side sliding bar 32 for the shoji 1 on the right side are connected by a connecting material across the vertical 14, and the left and right shoji 1, 1 are opened / closed and locked together. This can be done simultaneously with two handles 16.

The operation of each part when closing and locking the shoji 1 will be described in more detail with reference to FIG. When the handle 16 is operated to the closed side, as shown in FIG. 7A, the horizontal slide bar 32 is pulled rightward, and the pin stopper 40 is locked to the pin 37 at this time. The sliding member 44b of the corner drive 44 is also pulled together via 39, and accordingly, the shoji closing arm 45 pushes down the slider 22, so that the shoji 1 is drawn indoors. Thereafter, just before the shoji 1 is completely closed, as shown in FIG. 7 (b), the pin stopper 40 comes into contact with the release block 42, and at the same time as the shoji 1 is completely closed, as shown in FIG. The plate 39 comes into contact with the stopper 43 and is prevented from moving, and the pin stopper 40 rides on the release block 42 and the engagement with the pin 37 is released. By continuing to operate the handle 16 thereafter, the horizontal slide bar 32 is further pulled rightward, and as shown in FIG. 7 (d), the pin 37 moves in the long hole 38, so that the connecting plate 39 and the shoji closing arm 45 connected thereto do not move, only the horizontal slide bar 32 and the lock pin 48 fixed thereto slide to the right, and the lock pin 48 engages with the lock receiver 36 during this time. The shoji 1 is locked.
When the shoji 1 is opened, the reverse operation is performed, and only the horizontal slide bar 32 slides to the left until the lock pin 48 is removed from the lock receiver 36, and the pin stopper 40 is engaged with the pin 37 in the middle. The shoji closing arm 45 is pushed upward through the connecting plate 39 and the corner drive 44, and the shoji 1 is opened by the action of the urging member 47.

  As described above, the natural ventilation window can close and lock the shoji 1 with one action of the handle 16. Moreover, the horizontal slide bar 32 is attached to the connecting plate 39 of the interlocking member 50 so as to be slidable in the longitudinal direction of the invisible 13, and the shoji 1 is closed by the action of the pin stopper 40, the release block 42 and the stopper 43. By the way, after the shoji closing arm 45 and the connecting plate 39 are stopped, only the horizontal slide bar 32 and the lock pin 48 fixed thereto slide to complete the locking. Thus, the shoji 1 can be locked stably without applying excessive force. Release of the lock and release of the shoji 1 can also be performed with one action of the handle 16. Further, the shoji closing arm 45 is provided so as to follow the saddle frame 2, and the shoji 1 is drawn by pushing the slider 22 along the saddle frame 2 with the shoji closing arm 45, so the shoji closing arm 45 is not conspicuous. In addition, since an arm for drawing the shoji 1 is not separately provided between the lower arm 18 of the shoji 1 and the invisible 13, the design can be improved and the shoji 1 can be opened widely, and even when the shoji 1 is in any open / closed state. The shoji 1 can be closed.

  The present invention is not limited to the embodiments described above. The shoji can be provided with a balance weight on the heel, or on both the upper heel and the heel. The rotation axis of the shoji may be in a position shifted vertically with respect to the vertical center of the shoji. In this case, adjustment is made with a balance weight so that the center of gravity of the shoji comes to the position of the rotation shaft. Further, the shoji is not limited to the one in which glass is fitted, but can be a box-like panel formed of a metal plate or the like. A fence frame includes a vertical. The natural ventilation window of the present invention may be upside down from that of the embodiment, that is, open so that the shoji falls to the outside of the room.
