てきている。[Detailed description of the invention] Recently, as a slat lifting device for Venetian blinds, it has been installed on a drive shaft 1 suspended in a head box 3 for rotational driving, and screwed into a screw hole 12 in a drum mounting plate 11 of a bracket 10. The spiral cylindrical winding drum 2 rotates forward and backward with the rotation of the drive shaft 1, winds up and unwinds the lifting cord 4 whose upper end is attached to the winding drum 2, and moves the lifting cord 4 downward. As the lifting cord 4 is wound and unwound, the portion of the winding drum 2 around which the lifting cord 4 is wound is also moved around the drive shaft 1. The sleeve mounting plate 13 of the mounting bracket 10 rotates with the winding drum 2.
A slat elevating device for Venetian blinds, which is configured to move in and out as the screw is advanced and retracted, into a rotating sleeve 5 rotatably supported by the slat has been widely used.

コード４が巻取ドラム２周面の螺旋溝１４に順序
よく整列巻取り巻戻しされるものである。 That is, in the above-mentioned slat elevating device, the drive shaft 1 is rotated to move the portion of the winding drum 2 around which the elevating cord 2 is wound in and out of the rotating sleeve 5, and the elevating cord 4 is wound around the winding drum 2. When lifting and lowering the slat by attaching and unwinding, a load P due to the weight of the slat (or bottom rail) is always applied vertically downward to the lifting cord 4, and this load P is applied to the lifting cord 4. The cord 4 is stretched tightly without being slackened in the middle, so that the cord 4 is wound and unwound in order in the spiral groove 14 on the circumferential surface of the winding drum 2.

のトラブルが発生していたものである。 However, especially when lowering the slat by rewinding the lifting cord 4, one end of the slat (for example, the left end) collides with an obstacle and the lowering is stopped at that position. When the drive shaft 1 (i.e., the winding drum, etc.) continues to rotate, only the other slat (e.g., the right end) will descend further downwards, while the one that has stopped (e.g., the left end) will only move the lifting cord 4 more and more. When the lifting cord 2 is unwound and unwound, it becomes sagging or tangled, and the winding state of the lifting cord 2 around the circumferential surface of the winding drum 2 becomes disordered. The winding drum 2 may not be in a horizontal position horizontally, but may move up and down tilted to one side, resulting in an extremely unsightly appearance, or the lifting cord 4 may not be wound correctly, causing the winding drum 2 to fall on the rotating sleeve 5. Various troubles have occurred, such as the winding drum 2 not being able to move in and out, and the rotation of the drive shaft 1 also stopping.

行えるようにしたものである。 Therefore, the present invention is designed to prevent the slat from colliding with an obstacle during the lifting and lowering operation of the slat.
At the same time as the load P that had been applied to the lifting cord 4 due to the weight of the slats suddenly decreases, the rotation of the rotating sleeve 5, that is, the drive shaft 1, is automatically stopped, and the load is removed by removing obstacles, etc. When P is returned to its normal load, the rotary sleeve 5 and the like automatically become rotatable again, so that correct lifting and lowering operations of the slat can be performed with the slat always being horizontal horizontally.

ものである。 The configuration of the present invention will be explained below with reference to its embodiments.A spiral cylindrical drum is attached to a drive shaft 1 suspended in a head box 3 for rotational driving, and screwed into a screw hole 12 of a drum mounting plate 11 of a bracket 10. The winding drum 2 was rotated by the rotation of the drive shaft 1 while being screwed forward and backward, and the lifting cord 4 whose upper end was attached to the winding drum 2 was wound back and suspended below the lifting cord 4. As the slats are raised and lowered, and as the lifting cord 4 is wound and unwound, the portion of the winding drum 2 on which the lifting cord 4 is wound is also attached coaxially to the drive shaft 1, and is connected to the winding drum 2. In a Venetian blind slat elevating device configured to move in and out of the rotating sleeve 5 rotatably supported on the sleeve mounting plate 13 of the rolling bracket 10 as the screw advances and retreats, one of the circumferential surfaces of the rotating sleeve 5 is provided. For example, one or more engaging recesses 6 are provided in the circumferential surface of the opening to form a ratchet part 6', and an engaging piece 7 is installed directly under the ratchet part 6' using an arbitrary material such as a leaf spring. The engaging piece 7 is installed so that it can be elastically moved up and down vertically to a predetermined dimension using a bullet 8.
For example, a guide portion 9a is provided on a part of the drum mounting plate 11 of the bracket 10, and a guide portion 9b is provided diagonally above the guide portion 9a, for example, on the inner surface of the drum mounting plate 11 of the bracket 10.
(for example, a small roller), and the lifting cord 4 whose upper end is wound around the winding drum 2 is hung from the guide part 9b to the guide part 9a in order, and the slat is suspended from the hanging part,
The load P of the slat bends the ammunition 8 and guides the guide part 9.
In other words, the engaging piece 7 is in the lowered position.
尚、１５はスラツトの角度変換用テープを示
す。 Note that 15 indicates a tape for changing the angle of the slat.
上記の構成において、
正常作動時には、昇降コード４に常時荷重Ｐが
垂直下方に加わつているため、ガイド部９ａ即ち
係合片７が弾機８を屈縮して下降位置にあるが、
駆動軸１を回転してスラツトの昇降操作を行う過
程で、スラツトの下端が障害物に衝突する等して
停止すると、昇降コード４がたるむなどして上記
荷重Ｐが瞬時に減少し或は無くなるため、弾機８
が弾発復元してガイド部９ａ即ち係合片７が上昇
して、回転スリーブ５のラチエツト部６′に接触
し、その係合凹部６に係合する。 In the above configuration, during normal operation, since the load P is always applied vertically downward to the lifting cord 4, the guide portion 9a, that is, the engagement piece 7 bends and contracts the ammunition 8 and is in the lowered position.
In the process of rotating the drive shaft 1 to raise and lower the slat, if the lower end of the slat collides with an obstacle and stops, the lifting cord 4 will become slack and the load P will instantly decrease or disappear. Because of this, ammunition 8
The guide portion 9a, that is, the engagement piece 7 rises to come into contact with the ratchet portion 6' of the rotary sleeve 5 and engage with the engagement recess 6 thereof.
この係合片７と係合凹部６の係合によつて、ま

動軸１が停止し同軸上の巻取ドラム２も停止し
て、手動の場合は昇降操作ができなくなり、電動
の場合は通常、駆動軸１の回転は原動力とフリク
シヨンクラツチで伝達されているので、該クラツ
チが停止トルクで外れる。 Due to the engagement between the engagement piece 7 and the engagement recess 6, the rotation of the rotary sleeve 5 is first stopped, and the drive shaft 1 and the winding drum 2 on the same axis are also stopped. In this case, the elevator cannot be raised or lowered, and in the case of an electric drive, the rotation of the drive shaft 1 is normally transmitted through a motive force and a friction clutch, so the clutch is disengaged due to the stopping torque.
従つて、スラツトの一方端が障害物に衝突する
等で停止すると、直ちに回転スリーブ５の回転が
停止すると共にスラツト昇降装置全体（左、右両
方共）が停止するので、スラツトの水平状態が一
方に傾いたり、或は荷重のないまゝ昇降コード４
が巻取り巻戻しされて前述のようなトラブルが発
生するのを未然に防止しうる。 Therefore, when one end of the slat stops due to collision with an obstacle, etc., the rotation of the rotating sleeve 5 immediately stops, and the entire slat lifting device (both left and right sides) stops, so that the horizontal state of the slat is changed to one side. If the lifting cord 4 is not tilted or has no load,
It is possible to prevent the above-mentioned troubles from occurring due to the winding and unwinding of the film.

転スリーブ５は回転自在となつて駆動軸１が回転
し、原状通り自由に昇降コード４の巻取り巻戻し
を行つて、スラツトの昇降操作を行いうるもので
ある。 If the above-mentioned obstruction is removed, the slat hangs down normally again, and a load is applied to the lifting cord 4, the ammunition 8 is bent and contracted again by the load, and the engagement piece 7 is lowered. The engagement with the engagement recess 6 is disengaged, and the rotary sleeve 5 becomes freely rotatable, and the drive shaft 1 rotates, freely winding and unwinding the lifting cord 4 in its original state, and lifting and lowering the slat. It is possible to do this.
上記の如く、本考案における係合凹部６と係合
片７の係脱はスラツトによる垂直荷重をそのまゝ
垂直方向に作用して行うものであるから、構成簡
潔な上に係脱作用がシヤープかつ適確に行われる
特長があり、極めて効果的にスラツトの水平維持
作用を遂行しうる利点がある。 As mentioned above, the engagement and disengagement between the engagement recess 6 and the engagement piece 7 in the present invention is performed by applying the vertical load from the slat directly in the vertical direction, so the structure is simple and the engagement and disengagement action is sharp. It also has the advantage of being able to perform the slat leveling action very effectively.
