Description

[Detailed Description of the Invention] The present invention relates to a pulling mechanism for a sliding shoji in an aluminum sash.

In sliding shoji made of aluminum sash, a sliding stile is drawn and pressed against the frame surface in order to improve soundproofing and airtightness.
A conventional shoji pulling mechanism will be explained with reference to FIG. are connected to each other via rod 5,
The crescent 6 integrated with the tightening handle 3 is engaged with the crescent receiver 9 provided on the outer stile 8 of the outer shoji 7 by the tightening handle 3, and at the same time, the pull fitting 4 comes into contact with the frame 10 and the inner shoji is closed. 1 to the inside of the frame 10. At this time, the outer shoji 7 is a double-sided stile 2 and 8.
By fitting the smoke return on the inside and outside of the frame, the pull of the inner frame 2 is transmitted to the outer frame 8, and the outer frame 8 is also brought into close contact with the pull frame 10. Because the outer shoji 7 cannot be pulled in by the same amount as the inner shoji 1 due to adjustment errors and shape errors in the chimney return, it has the disadvantage that soundproofing and airtightness cannot be achieved completely.

The present invention aims to solve the above-mentioned drawbacks, and is characterized by the fact that the outer shoji is pulled together, and the amount of the pull is transmitted to the inner shoji, which is pressed against the inner shoji so that it comes into close contact with the frame. .

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 2 is a side view of the main part, and FIG. 3 is a cross-sectional view taken along the line of FIG.
13 is the outer stile of the outer shoji 14, 15
16 is a crescent that rotates together with the tightening handle 15, and 17 is a gear mounted eccentrically on the rotating shaft 18 of the tightening handle 15. It has an arcuate shape similar to the crescent 16, and is positioned in the middle of the crescent 16 as shown in FIG. Although the gear 17 is mounted eccentrically to the rotating shaft 18, if the gear is a cam-shaped gear, it is not necessary to eccentrically attach the gear 17 to the rotating shaft 18.

Numeral 19 is a crescent holder attached to the outer frame 13 of the outer shoji 14, and 20 is a gear provided on the outer frame 13, which meshes with the gear 17. A crank 21 has one end connected to the axis of the gear 20, and is rotatably supported by the crescent receiver 19, and the other end is connected to a slider 22 arranged vertically within the outer frame 13. ing. Reference numeral 23 denotes a pull fitting attached to the upper end of this slider 22, and a slope 24 is formed toward the outside. 2
Reference numeral 5 denotes a pull fitting attached to the lower end of the slider 22, and when the shaft 27 fitted in the elongated hole 26 rises upward, the end of the pull fitting rotates outward via the fulcrum 28 due to the action of a lever. It looks like it's pushing the frame.

Next, the operation of the above configuration will be explained.

Close the outer shoji 14 and the inner shoji 12 and align both frames 13 and 11. Therefore, tighten handle 1
When the crescent 16 is rotated by operating the crescent 16, it engages with the crescent receiver 19, rotates, and gradually draws the outer frame 13 inward. At this time, Crescent 1
The gear 17 rotating together with the gear 1 meshes with the gear 20 as the outer frame 13 is drawn, and the gear 17 rotates with the gear 20.
7 is transmitted, but at that time, the rotation is transmitted to the gear 20 while escaping the deviation of the outer frame 13 by the eccentricity of the gear 17, and the rotation of the gear 20 causes the crank 21 to rotate. Raise the slider 22.

As the slider 22 rises, the slope 24 of the puller fitting 23 at the upper end comes into contact with the frame 29 and pulls the outer shoji 14 inward, while the puller fitting 25 at the lower end rotates to frame the frame at the end. Press 29 to open the outer shoji 1
Pull 4 inward.

In this way, the center of the outer shoji 14 is pulled toward the inner shoji 12 by the crescent 16 and the crescent holder 19, and the upper and lower ends are pulled toward the inner shoji 12 by the pulling fittings 23 and 25 at both the upper and lower ends. By pressing it inward, both frames can be brought into close contact with the frame.

Next, when opening the shoji, turn the tightening handle 15 in the opposite direction to the above, the crescent 16 will rotate along the crescent receiver 19, and the gear 2 will rotate accordingly.
0 is also rotated in the opposite direction to the above by the gear 17,
As a result, the slider 22 descends via the crank 21, the respective pulling fittings 23 and 25 release their pulling action, and both shoji screens can be opened.

According to the present invention having the above structure and function, the outer shoji has a structure in which a pulling fitting is attached to the outer shoji to draw it inward, and the inner shoji is drawn together by the outer shoji and brought into close contact with the frame. As a result, the adhesion of the frames of the inner and outer shoji to each other is improved, and the adhesion to the frame is also improved, resulting in improved soundproofing and airtightness.
