The sash 1 has a vertically long pipe 5 arranged in vertical grooves 2 formed in the left and right vertical frames 1a, and the upper end of the pipe 5 is It is fixed to the sash 1 side, a screw plate 8 having a large lead angle is vertically movably inserted into the pipe 5, and a nut member 10 screwed onto the screw plate 8 is rotatably attached to the lower end side of the pipe. A spiral spring 9 is fitted in the outer periphery of the screw plate 8 in the pipe 5, and the upper end of the spiral spring 9 is located near the upper end of the pipe 5.
The lower end of the screw plate 8 is connected to the nut member 10, and the protruding lower end of the screw plate 8 is connected to the shoji 3 through the connecting member 7. And when installing it on the window, the spiral spring 9
Was preliminarily wound and given a constant initial spring pressure, and it was set so that it would not drop by its own weight when the shoji 3 was pulled up to the uppermost position.
かかるカウンタバランス機構では、障子3を下動させ
て行く際にねじ板8に螺合するナット部材10が円滑に回
動して螺旋ばね9を巻き締め操作することを要する。In such a counter balance mechanism, when the shoji 3 is moved downward, the nut member 10 that is screwed into the screw plate 8 is required to smoothly rotate to wind and tighten the spiral spring 9.
問題はこのナット部材10をいかにしてパイプ5の下端
に下方への抜け止めを図って回転のみ可能に支持するか
である。The problem is how to support the nut member 10 at the lower end of the pipe 5 so that the nut member 10 cannot be pulled out downward and can only rotate.
この点につき、従来ではナット部材10をパイプ5内の
下端部に挿嵌した状態で金属製のパイプ5の下端を絞り
加工して下方への抜け止めを図っていた。そのため、こ
の絞り加工が面倒で組み付け作業性に劣り、これらが原
因してコスト高になるところに第1の問題があった。With respect to this point, conventionally, the lower end of the metal pipe 5 is drawn in a state where the nut member 10 is inserted into the lower end portion of the pipe 5 to prevent the metal pipe 5 from coming out downward. Therefore, there is a first problem in that the drawing process is troublesome and the assembling workability is poor, and the cost is high due to these problems.
パイプ5の外面は製品の外観を整えるため、および腐
食防止のために着色処理を施すことが望ましい。しかし
従来方式では絞り加工時のパイプ外表面の損傷を避ける

することが困難になるところにも付随的な問題があっ
た。It is desirable that the outer surface of the pipe 5 be colored to improve the appearance of the product and prevent corrosion. However, in the conventional method, coloring is applied after drawing in order to avoid damage to the outer surface of the pipe during drawing, and the surface coloring of the pipe 5 to which parts such as the nut member 10 are assembled requires a considerable increase in cost. Was there. In order to facilitate the drawing process, it is desirable that the pipe 5 be a round pipe, and it is difficult to make the cross-sectional shape of the pipe 5 arbitrary (for example, hexagonal or octagonal). There was a problem.

おそれがあった。これを防止しようとすると、各部の寸
法に無理を生じるところにも問題があった。Further, it is desirable that the nut member 10 rotate at a fixed position at the lower end of the pipe 5. However, the conventional nut member 10 can move upward only by preventing the nut from falling out. Therefore, the vertical play of the nut member 10 makes it difficult to finely adjust the initial spring pressure of the spiral spring 9. Since the upward pulling force acts on the nut member 10 due to the tightening of the spiral spring 9, the upper end of the screw plate 8 may be disengaged from the nut member 10 when the shoji 3 is lowered to the lower limit. If this is attempted to be prevented, there is a problem in that the dimensions of each part are overwhelmed.
