BACKGROUND OF THE INVENTION
The present invention relates to a horizontal axis rotary window that opens and closes a shoji with a horizontal axis as a fulcrum.
[0002]
[Prior art]
A conventional horizontal axis rotary window has a bearing mounted at an intermediate height between the left and right vertical frame members constituting the window frame, and a horizontal axis protruding from the shoji cage between the two bearings. The shoji was rotated indoors and outdoors as a fulcrum, and the open state of the shoji was maintained by a curling stop provided between the window frame and the shoji.
[0003]
[Problems to be solved by the invention]
However, in the case of the conventional horizontal axis rotating window, the open state of the shoji is held by the anti-spinning, so when the wind blows, the anti-spinning fixing must be released and the shoji must be closed and fixed by human operation each time the wind blows. There was a problem that could not be.
[0004]
The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a horizontal axis rotation window capable of automatically closing an open shoji by wind pressure.
[0005]
[Means for Solving the Problems]
The horizontal axis rotary window of the present invention supports the shoji in an eccentric state above the middle height of the left and right vertical frame members that constitute the window frame, and attaches a weight to the indoor surface side of the shoji upper arm, and attaches the window frame The rod is supported horizontally so that it can be rotated by a motor on the indoor side of the unit, and the arm that presses the shoji rod from the indoor side is integrated with the rod in a direction perpendicular to the axial support direction of the rod It is characterized by projecting into Furthermore, the horizontal axis rotary window of the present invention is characterized in that the rod is pivotally supported at a height position substantially the same as the pivotal support portion of the shoji.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
First, in the first embodiment of the horizontal axis rotating window 1 according to the present invention, as shown in FIG. 1, the upper part of the left and right vertical frame members 21 and 21 constituting the window frame 2, for example, each vertical frame member 21 is placed from the top to the bottom. A weight 4 is provided on the interior surface side of the shoji upper arm 31 to maintain a balance while the shoji 3 is tilted. As shown in FIG. 3, the opening / closing means 5 that can automatically open and close the shoji 3 is provided on the indoor side.
[0009]
As shown in FIG. 2, the weight 4 is a weight plate 43 having a hat-shaped mounting bracket 41 fixed to the indoor surface side of the upper collar 31 and a bolt B projecting from the mounting bracket 41 toward the interior of the chamber with a hole 42. The weight plate 43 is inserted and adjusted in weight, and the weight plate 43 is securely fixed by tightening with a nut N so as not to be removed from the bolt B. Further, by preparing a number of weight plates 43 having different weights, the weight can be easily adjusted. Reference numeral 44 denotes a case for covering the weight 4 and adjusting the appearance, and reference numeral A is an angle for fixing the case 44 to the upper collar 31.
[0010]
As shown in FIG. 3, the opening / closing means 5 is a bearing 51 at the indoor surface side of the window frame mounting portion, specifically, on the left and right sides of the window frame 2, and at substantially the same height as the pivotal support of the shoji 3. , 51 are respectively provided, and the rod 52 is supported horizontally and rotatably by both bearings 51, 51. A pair of arms 53 are opposed to the left and right side portions of the rod 52, and in the axial support direction of the rod 52. The arm 53 presses the upper or lower portion of the shoji rod 32 from the indoor side by projecting integrally in a direction orthogonal to the rod and rotating the rod 52 by the motor M.
[0011]
Further, as shown in FIG. 4, if the arm 53 is held in a state of being inclined obliquely upward on the indoor side, the movable region of the shoji 3 is set in a range from the closed state to the contact with the front portion of the arm 53. Of course, the shoji 3 does not flutter greatly even when blown by the wind. In addition, if the weight 4 is set so as to widen the opening inclination angle of the shoji 3, the rod 52 is rotated to adjust the holding angle of the arm 53 as shown in FIG. The opening inclination angle of 3 can be narrowed, or vice versa. In addition, by rotating the arm 53 until the shoji 3 comes into contact with the rod 52, as shown in FIG. 12, the shoji 3 can be held in a fully opened state, and the upper outer surface of the shoji 3 can be easily wiped from the room. Is possible.
[0012]
Further, when the upper part of the shoji 3 is vigorously inclined indoors due to wind pressure or the like, in order to reduce the impact of the hook 32 hitting the front part of the arm 53, as shown in FIGS. The intermediate portion of the T-shaped buffer plate 54 is pivotally supported at the front portion, and a spring S is hooked between the base portion of the buffer plate 54 and the intermediate portion of the arm 53.
[0013]
This is because, when the pressure of the shoji 3 inclined toward the buffer plate 54 is smaller than the tension force of the spring S, the buffer plate 54 extends straight from the arm 53 as shown in FIG. One of the front portions of 54 projects from the front portion of the arm 53 to the outdoor side and comes into contact with the flange 32. On the other hand, when the pressure of the shoji 3 exceeds the pulling force of the spring S, the upper part of the buffer plate 54 is inclined indoors with respect to the virtual extension line of the arm 53 as shown in FIG. become. The other end of the buffer plate 54 performs its function when the shoji 3 is fully opened, as shown in FIG.
[0014]
In addition, a roller 55 is pivotally supported on the tip of the arm 53 and the tip of the buffer plate 54 so that the shoji guard 32 abuts on the roller 55 so that the shoji 3 can be closed smoothly. is there.
[0015]
The horizontal axis rotary window 1 described above can be used as follows by using a detection means (not shown) for measuring wind speed and rainfall.
[0016]
When the wind speed or rain amount data exceeding the limit value is measured from the detection means in the open state of the shoji 3, the motor M is rotated forward by a motor drive control device (not shown), and the rod 52 and the arm 53 are integrated with each other. As shown in FIG. 4, the tip of the buffer plate 54 pivotally supported by the arm 53 abuts on the upper part of the shoji guard 32 and presses the collar 32 in the upright direction, as shown in FIG. The shoji 3 is closed as follows.
[0017]
Further, when the data less than the limit value is measured from the detection means in the closed state of the shoji 3, the motor M is reversely rotated by the drive control device, and the rod 52 and the arm 53 are integrally reversed in conjunction with the rotation. Since the force with which the arm 53 presses the shoji 3 is released, the shoji 3 is naturally opened and inclined by the weight 4.
[0018]
Furthermore, the second embodiment of the horizontal axis rotary window 1 has a partial structure of the first embodiment, specifically, a structure in which the shoji 3 is pivotally supported in an eccentric state and a weight 4 is attached to the shoji upper collar 32. In addition, as shown in FIG. 8, the locking device 6 is attached to the indoor surface side of the shoji lower lower fold 33, and the locking means 7 is automatically fitted to and detached from the locking device 6 on the indoor side of the window frame mounting portion. And the shoji 3 is fixed in a closed state.
[0019]
As shown in FIG. 9, the locking tool 6 is fixed to the center part of the inner surface of the lower rod 33 or the left and right side parts so that the inverted L-shaped metal fitting 61 protrudes to the indoor side, and the tip of the protruding part. The pin 62 is erected on the part.
[0020]
On the other hand, as shown in FIGS. 8 and 10, the lock means 7 uses the support means 11 attached to the left and right sides of the indoor surface of the window frame member 22, and the horizontal shaft 71 is substantially abbreviated as the lower rod 33. A horizontal shaft 71 is slidably supported at the same height, a rack 72 is formed at the end of the horizontal shaft 71, and the pinion 73 engaged with the rack 72 is moved by the motor M so that the horizontal shaft 71 is slid. None, the horizontal shaft 71 is fixed with a hook 74 that fits into and out of the pin 62 of the locking tool 6.
[0021]
Further, as shown in FIG. 10, the support means 11 of the horizontal shaft 71 is supported by a pair of guide rollers 13 and 13 so as to sandwich the horizontal shaft 71, and both guide rollers 13 and 13 are covered with a rectangular tube case 12. To do.
[0022]
The horizontal axis rotation window of the present invention is not limited to the above embodiment. For example, in the second embodiment, a structure in which the locking means 7 is manually locked to the locking tool 6 may be used. Moreover, when the horizontal axis rotation window of 1st embodiment is comprised in a continuous window, the rod 52 is provided so that it may continue to each rotation window, and the arm 53 integrally provided in the rod 52 is used for the obstacle of each rotation window. 3 may be opened and closed simultaneously. Furthermore, if a ventilation room is provided in the roof ridge of a meeting place or factory, and the horizontal axis rotating window of the present invention is attached to the four sides of the ventilation room, only the horizontal axis rotating window in one direction is closed in the strong wind, and the other direction Since the horizontal axis rotary window is open, ventilation can be performed well.
[0023]
Further, if the horizontal axis rotation window has a structure in which the second embodiment is added to the first embodiment, each motor M that moves the arm 53 and the lock means 7 is moved in order by the drive control device, thereby opening the shoji in the open state. After forcibly closing 3 with the arm 53, the shoji 3 can be automatically fixed in the closed state by the lock means 7, and after the lock means 7 is removed in the reverse manner, the arm 53 is moved and closed. The shoji 3 in the state can be automatically opened.
[0024]
【The invention's effect】
The horizontal axis rotation window of the present invention pivotally supports the upper part of the shoji in an eccentric state and is provided with a weight on the indoor surface side of the upper shoji, so the upper part of the shoji falls into the indoor side when there is no wind or a breeze It can be opened naturally and the shoji can be held in an open state.However, depending on the wind and wind pressure, the shoji area at the lower part of the shaft support is wider than the shoji area at the upper part. The side part is pushed into the room, and the shoji is naturally closed. As a result, the indoor environment can be kept comfortable.
[0025]
In addition, when the rod is rotated by a motor, the arm provided integrally with the rod pushes the open shoji in the closing direction, so that the opening angle of the shoji can be adjusted and the shoji can be automatically closed. it can. Further, in the state where the shoji is closed, conversely, if the rod is reversed by a motor and the arm integrally provided on the rod releases the force of pushing the shoji, the shoji can be automatically opened by the weight. Therefore, by using the detection means for measuring the wind speed and rainfall, the shoji can be forcibly opened and closed based on the data of the detection means. Furthermore, as in the invention described in claim 2, by supporting the rod at substantially the same height position as the pivotal support portion of the shoji, the function of the arm can be maximized and the shoji can be held in the fully open state. It becomes possible.
