Abstract

A sectional honeycomb curtain and a driving apparatus (1) therefor. The apparatus (1) comprises: a first rope winding drum (10) and a second rope winding drum (11) that are arranged side by side on an upper beam (3) of the sectional honeycomb curtain; two driving mechanisms (12) used for respectively driving the first rope winding drum (10) and the second rope winding drum (11) to rotate, and to move froward and backward in an axial direction; two end limiting members (13) that are respectively disposed at the positions of the first rope winding drum (10) and the second rope winding drum (11) close to two ends and are relatively fixed to the upper beam (3); a first driving member (15) and a second driving member (16) that are correspondingly fixed on the first rope winding drum (10) and the second rope winding drum (11), respectively; and a first limiting plate (17) and a second limiting plate (18) that are arranged in parallel between the first driving member (15) and the second driving member (16). The first limiting plate (17) is located at the end close to the first driving member (15), and the second limiting plate (18) is located at the end close to the second driving member (16); moreover, the first limiting plate (17) and the first driving member (15) are fixed in the axial direction and are relatively movable in a circumferential direction, and the second limiting plate (18) and the second driving member (16) are fixed in the axial direction and are relatively movable in the circumferential direction.

Abstract

A take-up device for a curtain includes a pull-cord, a reel mounted to a top beam of the curtain, an actuating mechanism for actuating the reel to rotate to retract or release the pull-cord, and a braking mechanism for braking the pull-cord. The reel defines a winding groove and an actuating slot. The actuating mechanism is a flat spiral-spring assembly. The flat spiral spring assembly includes a wheel arranged in parallel with the reel and a flat spiral-spring. An end of a reed of the flat spiral-spring is wrapped around the wheel, and an opposite end of the reed is fixed in the actuating slot. The top end of the pull-cord is wound on the winding groove, and an opposite end of the pull-cord extends out of the winding groove, extends through the braking mechanism, and then is fixed to a curtain body of the curtain.

Abstract

A pull-cord control device for a curtain without an operating cord, comprising a base (1) and a press plate (2) which is pivotally connected to one end of the base (1) by means of a rotating shaft (42); the side of the base (1), facing toward the press plate (2), is provided with a first friction shaft (11); the side of the press plate (2), facing toward the base (1), is provided with a second friction shaft (21) which is arranged to be staggered with the first friction shaft (11); the end of the press plate (2), being set at a distance farther from the rotating shaft (42), is provided with a fixed rod (41); one end of a pull-cord (3) of a curtain is connected to a cord retracting and releasing device (5) of the curtain, and the other end of the pull-cord (30) passes through the first friction shaft (11) and the second friction shaft (21) and is connected to a curtain body (6) of the curtain after passing the fixed rod (41); when the curtain body (6) moves vertically, the press plate (2) is driven by the pull-cord (3) to rotate around the rotating shaft (42) between a clamping position and a released position relative to the base (1), and when the press plate (2) is positioned in the clamping position, the second friction shaft (21) enables the pull-cord (3) to wind around the first friction shaft (11) and the second friction shaft (21). By means of the pull-cord control device for a curtain without an operating cord, the height of a curtain can be freely adjusted, facilitating the raising and lowering of a curtain.
