【考案の詳細な説明】 〔産業上の利用分野〕 本考案は、横型ブラインドのスラットを昇降するために
昇降コードを巻取り巻降ろしするブラインドの昇降コー
ド巻取り装置に関するものである。[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a blind lifting cord winding device that winds and lowers a lifting cord for lifting a slat of a horizontal blind.
横型ブラインドにおいて、昇降コードを巻取ドラムに巻
取り巻き降ろしすることによってスラットの昇降を行な
う型式のものが広く使用されているが、このような型式

ドが前に巻取られたコードの間に挾さまって、巻降ろし
の際にスムースに巻降ろされない場合もある。In horizontal blinds, a type in which an elevating cord is wound up and down on a take-up drum to raise and lower a slat is widely used.However, in the elevating cord winding device of such a type, the elevating cord is wound. When the take-up drum is wound around one place, the take-up diameter increases as the take-up amount of the elevating cord increases, and the take-up speed sequentially increases. In addition, the hoisting and lowering cord may be caught between the previously wound cords and may not be smoothly unwound when unwinding.

るを得ず、従って、その中に巻取ドラムの雄ネジと噛合
う雌ネジを配置することは、益々厄介なことになる。However, in such a structure, a male screw portion is formed along the entire length of the winding drum, and a female screw is formed at one end of the drum receiver that supports the winding drum. The take-up drum must be moved along the thread. However, forming a female screw at one end of the drum receiver requires a troublesome work. In addition, in order to improve the appearance of the blinds, the width of the slats is gradually narrowed, and while the slats with a width of 35 mm were used in the past, the slats with a width of 15 mm are now used. As a result, the head box that supports the blind must be downsized, and the drum receiver built into it must be downsized. Therefore, the female screw that meshes with the male screw of the take-up drum must be placed in it. Becomes more and more troublesome.

昇降コード巻取り装置を提供しようとするものである。The present invention solves the above-mentioned problems in the conventional horizontal blind lifting cord winding device, and is configured to move the winding drum that winds the lifting cord in the axial direction as the winding drum rotates. As described above, it is an object of the present invention to provide a blind lifting cord winding device capable of reducing the size of the head box by eliminating the need to provide a female screw to be screwed onto the winding drum.

しようとするものである。Further, in the conventional winding drum having the thread groove over the entire length, the lifting cord may be wound around the thread portion of the screw, but the present invention eliminates such possibility. The present invention aims to provide a lifting cord winding device for the blind.

ある。As a means for solving the above problems, the present invention mounts a winding drum, which winds an elevating cord for elevating a slat, in the head box of a horizontal blind so as to move in the axial direction with its rotation, A blind lifting cord winding device in which the upper end of a cord is attached to the winding drum, and the lifting cord is wound in a spiral shape on the winding drum as the winding drum rotates. A male screw portion is integrally formed near the end of the winding drum on the side opposite to the lifting cord attachment end of the above, and is attached to the inner wall of the substantially box-shaped drum receiver that is open upward to rotatably support the winding drum. It is an object of the present invention to provide a blind lifting cord winding device characterized in that a rack portion that meshes with the male screw portion is formed.

できる。As described above, according to the present invention, the winding diameter of the lifting cord is sequentially increased by unwinding and winding the lifting cord in a spiral shape on the winding drum as the rotary shaft rotates. Alternatively, the lifting cord can be smoothly moved up and down without the fear that the lifting cord will be caught between the previous lifting cords and be smoothly unwound. However, since there is no thread groove over the entire length of the take-up drum, there is no possibility that the lifting cord will ride on the threads and cut. Further, since it is not necessary to form a female screw that is screwed onto the winding drum on the drum receiver, the entire drum receiver can be formed in a small size, and the entire blind head box can be made compact.
