Problems solved by technology

[0003] However, in the prior art, the guide wheels are mostly set in a horizontal manner, so there will be a large angle turning when the stay rope goes around the guide wheel and extends down to the curtain, which will easily cause an increase in frictional resistance , so that the smoothness of the curtain during the opening and closing process will be affected

Embodiment Construction

[0016] Please see first figure 1 The curtain 10 shown in the figure comprises an upper rail 12, a curtain 14 located below the upper rail 12, and four stay cords 16 extending from the upper rail 12 to the curtain 14, and the rope guide device 18 of the present invention mainly One set is arranged at both ends of the upper rail 12, and each set of guide rope devices 18 is used in conjunction with two stay ropes 16. Since the structures of the two sets of guide rope devices 18 are identical, only one set will be described here. see again figure 2 and image 3 , The rope guiding device 18 of the present invention includes a guide wheel seat 20 , two first guide wheels 30 , and two second guide wheels 40 .

[0017] The guide wheel base 20 has a rectangular bottom wall 21 , two opposite end walls 22 , an inner side wall 23 , and an outer side wall 24 . The two ends of the top surface of the bottom wall 21 respectively have a bearing part 25 protruding upwards, and the bearing p...

Abstract

A rope guiding device for a curtain includes a guiding wheel base and a first guiding wheel; a pull rope inlet and a pull rope outlet perpendicular to the pull rope inlet are formed in the guiding wheel base; the first guiding wheel is arranged on the guiding wheel base and is positioned on an intersection between the extension direction of the pull rope inlet and the extension direction of the pull rope outlet; and an included angle of less than 90 degrees is formed between the axial direction of the first guide wheel and the extension direction of the pull rope outlet. Accordingly, the rope guiding device can reduce the turning angle of the pull rope so as to reduce the fraction resistance acted on the pull rope, and the smooth degree of opening-closing of a curtain sheet can be improved.

Description

technical field [0001] The invention relates to curtains, in particular to a rope guide device for curtains. Background technique [0002] The curtain of the curtain is mainly driven by the pull rope of the retractor. Usually, one or more sets of guide wheels are set at the turning point where the pull rope extends from the retractor to the curtain, and the pull rope is wound around these guide wheels. Afterwards, the wheel can produce an angle turning, and then drive the curtain to open and close. [0003] However, in the prior art, the guide wheels are mostly set in a horizontal manner, so there will be a large angle turning when the stay rope goes around the guide wheel and extends down to the curtain, which will easily cause an increase in frictional resistance , so that the smoothness of the curtain in the opening and closing process will be affected jointly. Contents of the invention [0004] The main purpose of the present invention is to provide a rope guide devi...
