Description

Shutter curtain

Technical Field

The invention relates to the technical field of blind curtains, in particular to a blind curtain.

Background

Blinds can both increase the privacy of a room and present a potential hazard. For example, in a traditional manual blind, a lifting circulating pull rope with a vertical weight handle is arranged on the side surface, and the pull rope is dissociated outside a window body, so that children are easily injured accidentally. In addition, the traditional manually controlled pull rope is easy to damage the window curtain due to different force application sizes and directions of users, and the service life of the window shutter is shortened. The development and change of things are caused by contradictory motions, in order to cancel a pull rope and solve the potential safety hazard caused by the pull rope, spring roller blinds are adopted to replace the pull rope in the market at present, but all upper beams of the curtain are fixed at the top of a window, and only a lower beam can be used for lifting and controlling light. When in daily use, users often want the upper half of the window to transmit light and the lower half to shade light. For example, when getting up, a user may want to have light in a room and better privacy. The window coverings that achieve the above-described objectives or functions are collectively referred to in the industry as day and night curtains. Most of the curtains are made of two different materials, one of the two materials has good light transmission performance and the other material has good light shading performance. However, the curtain is not beautiful enough and the using effect is not ideal enough.

In addition, the upper beam of the blind curtain in the prior art is fixed, and the light needs to be turned on when the light is dark, or the shading area can be adjusted only by adjusting the bottom curtain of the blind curtain.

example 1:

as shown in fig. 1-15,32-33, a window blind includes a frame 511 and a window covering 500 installed in the frame 511. The blind 500 is a blind. The frame 511 includes a left bezel 512, a right bezel 513, an upper bezel 514, and a lower bezel 515. The left frame 512, the right frame 513, the upper frame 514, and the lower frame 515 form a quadrangular frame structure. The window covering 500 is fixedly mounted within the frame 511. A first side groove rail 600 is provided in the left frame 512, and a first slider 508 and a second slider 509 are slidably attached to the first side groove rail 600. A second side groove slide rail 601 is arranged in the right frame 513, and a third slide block 518 and a fourth slide block 519 are slidably mounted on the second side groove slide rail 601. The first sliding block 508 is fixedly installed at one end of the upper cross beam 502 of the blind 500 through a screw or a bolt; the second slider 509 is fixedly installed at one end of the lower rail 200 of the blind 500 by a screw or a bolt; the third slider 518 is fixedly mounted at the other end of the upper cross beam 502 of the blind 500 by a screw or a bolt, and the fourth slider 519 is fixedly mounted at the other end of the lower rail 200 of the blind 500 by a screw or a bolt. The first slider 508 and the second slider 509 are both on one side of the window covering 500, and the third slider 518 and the fourth slider 519 are both on the other side of the window covering 500. The bottom of the headrail 100 is fixedly connected to the top of the upper beam 502 of the window covering 500. The upper beam 502 and the left end of the upper rail 100 are fixedly connected together through a first sleeve 11, and the upper beam 502 and the right end of the upper rail 100 are fixedly connected together through a second sleeve 12. The upper beam 502 and the upper rail 100 can move up and down within the frame 511 by the action of the first slider 508 and the third slider 518. The lower guide rail 200 can be moved up and down within the frame 511 by the action of the second and

fourth sliders

509, 519. The blind 500 is extended or shortened within the frame 511 by the action of the slider, thereby adjusting the shading area of the blind 500. In the present embodiment, the first slider 508, the second slider 509, the third slider 518, and the fourth slider 519 each have a ball 700.

When the handle 113 is rotated, the first magnet of the first link mechanism in the upper rail 100 or the lower rail 200 is attracted to the inner wall of the left frame 512, and the second magnet of the second link mechanism is attracted to the inner wall of the right frame 513. The blind 500 achieves the positioning of the upper cross beam 512 and the upper rail 100 by the first linkage and the second linkage in the upper rail 100. Similarly, a first magnet on the first linkage in the lower rail 200 is attracted to the inner wall of the left frame 512, and a second magnet on the second linkage is attracted to the inner wall of the right frame 513. The blind 500 realizes the positioning of the lower rail 200 by the first link mechanism and the second link mechanism in the lower rail 200. A first screw 114 is screwed into one end of the first screw 103; a first nut 104 is sleeved on the other end of the first screw 103 close to the rotating connecting rod 602. A second screw 151 is screwed into one end of the second screw 7; a second nut 15 is fitted over the second screw 7 at the other end thereof adjacent to the rotating link 602.

Example 21:

unlike embodiment 20, the blind curtain of the present embodiment uses the upper rail 100 or the lower rail 200 with the lock box in fig. 22 and 23.
