Jalousie curtain structure and combination method thereof

Abstract

The invention discloses a Venetian blind structure and an assembling method. The Venetian blind consists of a plurality of vanes between an upper beam and a lower beam, a pulling string and a ladder string. The vanes are arranged in parallel below the upper beam at regular interval from each other; the pulling string is positioned on the two sides of the vanes and adjacent to the ladder spring; at least one through-hole is opened on at least one side of each vane which corresponds to the ladder string; a connector is arranged between the ladder string and the vanes to combine the ladder string, the pulling string and the vanes, thus fixing and limiting the position of the vanes and achieving better shielding effect.

Description

technical field [0001] The present invention relates to a venetian blind, more specifically, to a venetian blind structure with better shielding effect and its combination method. Background technique [0002] Traditional venetian blinds generally include a plurality of ladder ropes and pull ropes connected between an upper beam and a lower beam, and a plurality of blades arranged between the ladder ropes in a parallel manner above and below, wherein each A blade will be provided with several perforations in the central part along its long axis direction at an appropriate distance, for a stay rope used to pull the lower beam upwards, and can pass through the corresponding perforations sequentially from top to bottom. The pull rope is used to pull the lower beam to move upwards, and passes through to collect the blades in sequence. The closed state for entry into the room, or the open state for light to enter. [0003] The disadvantage of using this curtain is that even if ...

Problems solved by technology

[0007] However, this type of curtain usually has a considerable diameter due to the stay cords used to carry the blades and the lower beam, and the position where the blades are adjacent to the stay cords is not flexible, so the two adjacent blades are turned up and down. In the overlapping state, the stay cord sandwiched between the overlapping parts of the two blades will hinder the two blades so that they cannot be closely approached, and a gap will be formed between the two blades, so that it blocks the light. The effect is still limited, even if a thinner stay rope is selected, the gap will still be left between the two blades, and the strength of the stay will be insufficient due to the thinner stay rope, so it cannot bear the weight of all the leaves and the lower beam. Furthermore, it is easier for the user to cause damage to his hands when he pulls up the curtain

[0008] Although U.S. Patent No. 5,582,226 discloses a curtain structure in which the stay cord does not pass through the perforation, its two ends pass through the holes on both sides of the blade from top to bottom, and the twisted ladder rope transverse spokes will cause the blade to rotate unsmoothly. situation, and the smooth rotation of the interference vane is more evident after the lower beam of the curtain is pulled up for a certain distance

[0009] The applicant of this case has two other U.S. patents No. 6,729,379 and No. 6,854,504, which provide curtains that are pre-set with loops on the pull cords and pass through to connect with the rods on both sides of each blade. This design can save the general blind type Drawstrings in curtains, but are only particularly suitable for soft blades; as for the curtain structure with rings and hard blades, such as the structure disclosed in U.S. Patent No. 6,192,963, although the rings on the ladder ropes are still used , so that the drawstring can be threaded therein, but this structure still causes the problem that the blades will slip from the side of the curtain
