Problems solved by technology

However, the extension and retraction of the curtain body of the existing blinds and the control of the inclination angle of the curtain blades are achieved by two independent mechanisms, which is quite inconvenient to use and operate.
Although there are other integrations of the aforementioned two mechanisms to form a single control module, such as the Chinese Taiwan Patent No. M269349 and the Chinese Taiwan Patent No. M356795, the aforementioned single control module directly passes through all the curtain blades with the lifting pull cord, so that The lifting rope is located between the two warp lines of the ladder rope, so when adjusting the inclination angle of the curtain blades, the two adjacent curtain blades will not be able to get a good close effect, so there will be light leakage

Embodiment Construction

[0095] In order to illustrate the present invention more clearly, a preferred embodiment is given and described in detail in conjunction with the accompanying drawings as follows. Please refer to Figure 1 to Figure 4 Shown is a venetian blind 1 according to a preferred embodiment of the present invention, which includes an upper beam 10 , a lower beam 11 , a plurality of curtains 12 , a plurality of ladder cords 13 and a plurality of lift cords 14 . Wherein, each ladder rope 13 includes two two warps 13a arranged along the direction of the upper beam 10 toward the lower beam 11 and a plurality of wefts 13b connecting the two warps 13a, and these wefts 13b respectively support a curtain 12, so that the curtain 12 is suspended between the upper beam 10 and the lower beam 11; the lifting stays 14 are respectively adjacent to a warp 13a and are located outside the curtain 12, and the lifting stays 14 are controlled to change The length is released so that the lower beam 11 moves...

Abstract

The window blind comprises an input mechanism, a frequency modulation output mechanism and an output clutching mechanism. The input mechanism changes a lower beam position, the frequency modulation output mechanism is started at the low-point position of the lower beam to drive the turnover of the curtain sheets between two positions; the output clutching mechanism is driven under the action of the input mechanism to move to the high-point position, or under the action of the input mechanism. The transmission paths of the frequency modulation output mechanism and the output clutching mechanism are provided with stroke delay mechanism to delay the influence time of mutual transmission so as to realize folding and unfolding of the curtain chip angle and curtain body through a single control module.

Description

technical field [0001] The present invention relates to venetian blinds; in particular, it refers to a venetian blind in which the angle of the slats and the opening and closing of the slats are controlled by a single control module. Background technique [0002] Known vertical lift curtains, in order to use the curtain body of the curtain to be folded or unfolded up and down to determine the area that the curtain body can cover, and according to the difference in the shape or appearance of the curtain body, can be roughly divided into: venetian blinds, honeycomb blinds , roller blinds and soft gauze curtains. As the name suggests, the venetian blind has a plurality of horizontally arranged long plate-shaped curtains, and these curtains are suspended between the upper beam and the lower beam by ladder ropes. The shaded area of ​​the curtain can be determined by unfolding the curtain from top to bottom or stacking from bottom to top. According to the habit of most people usi...
