Description

[Detailed Description of the Invention] Industrial Field of the Invention [0007] The present invention is a push-push that can be bent only on one side of a window that is opened and closed by contacting and separating a window frame of a horizontal frame of a shoji screen with respect to the corresponding horizontal frame. The present invention relates to a device that opens and closes by pushing and pulling a pull chain.

Problems to be solved by the conventional technology and device For example, when opening and closing a projecting window that is hinged freely on the upper frame of the shoji on the upper frame of the window frame to the outdoor side with the push-pull chain, An open / close driver supporting a sprocket that accommodates the push-pull chain in a slender box is installed at the center of the lower frame of the window frame in a horizontal position with the rotation axis of the sprocket facing vertically. The tip of the push-pull chain is attached to the center of the lower frame of the shoji, and the sprocket is rotated by the driving force of the motor to push or pull the push-pull chain from the opening / closing drive to open or close the shoji. Common, but for example
When forming a continuous window in which a plurality of such protruding windows are connected in the horizontal direction and driving the opening / closing driver of each window in conjunction with each other,
A horizontal drive shaft driven by a motor is arranged on the lower surface of the open / close driver so as to connect the open / close drivers, and the drive shaft is passed through a conversion device for converting the drive direction from the horizontal direction to the vertical direction. It is necessary to take a structure to connect to the rotating shaft of the sprocket of each open / close driver, and the open / close driver has a structure in which the above-mentioned drive direction conversion device is attached to the lower surface of the open / close drive and has a large vertical thickness. There is a drawback that it is difficult to hide in the lower frame of the frame, and because the push-pull chain is pushed out from the center of the lower frame of the window frame,
Not only is the push-pull chain exposed at the center of the window when the shoji is opened, but it is also annoying that the tip of one push-pull chain is attached to the center of the lower frame of the shoji. Because of this, the shoji tend to rattle when it is opened or closed or when it is fanned by the wind, and the hinged part of the shoji is fragile.

As means for solving the above problems, as a means for solving the above problems, the window opening / closing device of the present invention is configured to be opened / closed by contacting / separating the window frame of the horizontal frame of the shoji with the corresponding horizontal frame. Along the left and right vertical frames of the window frame, the pair of open / close drivers supporting the sprocket that engages with the push-pull chain that can be bent only on one side in the elongated box are rotated. The shaft is installed in a vertical posture parallel to the horizontal frame of the window frame, the tips of each push-pull chain are attached to the left and right sides of the frame of the shoji screen, and each sprocket is connected by a transmission shaft in the horizontal direction. The transmission shaft is connected to the motor.

The operation and effect of the present invention With the above configuration, when the sprocket of both open / close drivers is rotated in the forward direction by the drive of the motor through the transmission shaft, both push-pull chain are pushed out from the open / close driver and The left and right sides of the frame are pushed to open the window,
When both sprockets are rotated in the opposite direction, both push-pull chains are drawn into the opening / closing driver, and the shoji doors are pulled toward the window frame side to close the window. Since it is installed along the vertical frame of the window frame and connected by horizontal transmission shafts, the opening / closing driver should be placed in the vertical frame of the window frame and the transmission shaft in the horizontal frame. It also makes it easier to conceal, and when driving the opening / closing driver of each window as a continuous window, simply connect the opening / closing drivers of the adjacent windows with a horizontal connecting shaft. By putting it in the frame, it is also possible to easily make it a concealed structure, and since the push-pull chain is pushed out from both vertical frames of the window frame, when opening the shoji,
The push-pull chain is exposed at both ends of the window, making the appearance sleek, and the tips of the two push-pull chains are attached to the left and right sides of the frame of the shoji screen. It is well opened and closed, and there is little rattling even if it is blown by the wind, and the supporting parts such as the hinged part of the shoji screen are prevented from being damaged, and it is possible to reliably open and close the shoji screen over a long period of time. There is.

Embodiment An embodiment of the present invention will be described below with reference to FIGS. 1 and 2.

In the figure, reference numeral 1 denotes a projecting window in which an upper frame 2a of a window frame 2 is hinged to an upper frame of a shoji 3 so that it can be freely swung to the outdoor side, below the projecting window 1 and inside a window frame 22. A fixed window 21 in which a fixed shoji (not shown) is fitted is formed in series, and the left and right vertical frames 2b of the protruding window 1 are connected to the vertical frame of the fixed window 21 from their lower ends.
A pair of left and right opening / closing drivers 5 for opening and closing the shoji 3 are housed so as to extend over the upper end portion of 22b. The opening / closing driver 5 is an elongated box 6 as shown in detail in FIG.
The push-pull chain 7 which can be bent only on one side is housed therein, and the sprocket 8 which meshes with the push-pull chain 7 is rotatably supported by the rotary shaft 9. 5 is a vertical posture in which the rotary shaft 9 of the sprocket 8 is oriented along the lower frame 2c of the window frame 2 and the entrance / exit 10 of the push-pull chain 7 is directed to the outdoor side. The tips of the push-pull chain 7 drawn out from the doorway 10 of each opening / closing driver 5 are attached to the lower ends of the left and right vertical frames of the shoji 3 by means of the fixtures 11. .
