【考案の詳細な説明】
本考案はひも引きロールブラインドの滑車装置
の改良に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement of a pulley device for a string-pulling roll blind.
ロールブラインドのひも掛け滑車の外径をケー
スの内径に近づけると、ひもの滑車からの外れは
防止されるが、そのままでは滑車を外さないと、
ひもの掛け替えができないという問題が起きる。 If you bring the outer diameter of the roll blind string pulley closer to the inner diameter of the case, the string will be prevented from coming off the pulley, but if you do not remove the pulley,
The problem arises that the string cannot be replaced.
本考案の課題はケースの内径よりもわずかに小
さい外径の滑車を備えた装置であつて滑車を取外
さなくてもひもを着脱できるものを提供すること
にある。 The object of the present invention is to provide a device equipped with a pulley having an outer diameter slightly smaller than the inner diameter of the case, which allows a string to be attached and detached without removing the pulley.
前記課題を達成するため本考案の装置は滑車の
外周にひもの断面に相当する切欠きを備え、その

4をケース6に固定する。 The apparatus of the present invention will be explained based on the embodiments shown in the drawings. As shown in FIG. 1, a bearing sleeve 3, an elastic plate 4, and a brake drum 5 are sequentially stacked and fixed to a bracket 1 via rivets 2. The inner periphery of the case 6 is rotatably fitted onto the flange-shaped rotating surface 3a of the bearing tube 3, and is held between the elastic plate 4 and the bracket 1. A rotating shaft 7 is fitted into the bearing sleeve 3, and a roll 9 around which a screen 8 is wound is fixed to the rotating shaft. A coil spring 10 is fitted to the brake drum 5, and a cap body 11 is fitted to the coil spring. The cap body 11 is integrally fixed to the rotating shaft 7, and the inner peripheral protrusion of the cap body 11 is inserted between the protrusions at both ends of the coil spring 10. A pulley 12 is fitted to the cap body 11 and rotated together, and a string 13 is hung on the pulley 12. Put the lid 14 on the case 6, and tighten the lid 1 with the screws 15.
4 to the case 6.
滑車12はひも13を直接掛ける環状輪12a
とその環状輪を保持する保持輪12bからなる。
環状輪12aは、第2図及び第3図に示すよう
に、金属板を二枚合わせたものであり、その外周
の一部にひも13の断面よりも少し大きな切欠き
20が設けられる。 The pulley 12 is an annular ring 12a on which the string 13 is directly hung.
and a retaining ring 12b that holds the annular ring.
As shown in FIGS. 2 and 3, the annular ring 12a is made of two metal plates put together, and a notch 20 slightly larger than the cross section of the string 13 is provided in a part of its outer periphery.
第4図に示すように、ケース6の内周と環状輪
12aの外周の空〓の幅はひも13の直径よりも
小さいため、ひも13を全周にわたり滑車12と
ケース6の間から引出したりはめ込んだりするこ
とはできない。 As shown in FIG. 4, since the width of the space between the inner circumference of the case 6 and the outer circumference of the annular ring 12a is smaller than the diameter of the string 13, the string 13 can be pulled out from between the pulley 12 and the case 6 all around the circumference. You can't fit it in.

る。 However, as shown in FIG. 5, when the notch 20 is turned downward, the string 13 is pulled out from the notch 20, and the pulley 12 is rotated once in the direction of the arrow, the string 13
will come off the pulley 12 naturally. Also, as shown in FIG. 6, the string 13 is hung on the notch 20 and
When the string 13 is rotated once in the direction of the arrow, the string 13 is automatically hooked onto the pulley 12. When the pulley 12 rotates in either direction, the protrusion of the cap body 11 integrated with the pulley loosens the coil spring 10 and prevents the braking action, so the pulley 12 can rotate freely.
上記のとおり、本考案の滑車はその外径とケー
スの内径の差が小さいため、使用中、ひもが滑車

とが可能であるから、ひもの取換え作業は著しく
容易になる。 As mentioned above, the pulley of the present invention has the advantage that the difference between its outer diameter and the inner diameter of the case is small, so the string does not come off the pulley during use. Unlike conventional models, it is possible to attach and remove the string while the pulley is attached, making the task of replacing the string significantly easier.
