Description

Technical Field

[0001] The present invention relates to the technical field of curtains, and particularly relates to a vertically height-adjustable accordion curtain. Background Art

[0002] Curtains are essential household items, mostly made of cloth, linen, yarn, aluminum sheets, wood, metal materials, etc., and have the functions of shading, heat insulation and adjusting indoor light. The lifting of the folding curtain of a conventional accordion curtain is controlled by the lifting of the lower rail, that is to say, the folding curtain rises from the bottom up. Therefore, when sitting next to a window, if one hopes that the sunlight can enter from the upper side of the window to increase the brightness, and also hopes to use the folding curtain to cover the lower side of the window to prevent the sunlight from shining on the body or protect privacy, the demand cannot be achieved by a conventional accordion curtain. Summary of the Invention

[0003] The purpose of the present invention is to provide a vertically height-adjustable accordion curtain, which adjusts the vertical height of the folding curtain from above or below to meet different usage requirements.

[0004] The above technical purpose of the present invention is achieved by the following technical solutions: a vertically height-adjustable accordion curtain, including four mounting codes distributed in a rectangular shape, two bead chains respectively arranged between two mounting codes on the same side and extending along the vertical direction, two tracks distributed vertically and with both ends respectively close to the two bead chains, a folding curtain arranged between the two tracks, and four height adjusters respectively arranged at both ends of the two tracks and used for fixing at any height of the adjacent bead chain.

[0005] The further setting of the present invention is: an opening limit groove extending along the length direction is arranged on the track, the opening limit grooves of the two tracks are close to each other, and limit strips for inserting into the opening limit grooves of the two tracks are respectively arranged at the upper and lower ends of the folding curtain.

[0006] The further setting of the present invention is: the height adjuster is a sealing clip with one end inserted and fixed at the end of the track and used for clamping the bead chain, the clamping part of the sealing clip faces the indoor direction after the accordion curtain is installed, and the sealing clip covers the opening limit groove.

[0007] The further setting of the present invention is: anti-slip strips arranged in a row are arranged on the part of the sealing clip for clamping the bead chain.

[0008] The further setting of the present invention is: the cross-sectional structure at any position along the length direction of the track is the same, and the track is made of PVC material.

[0009] A further setting of the present invention is as follows: The bead chain includes a drawstring and a plurality of beads arranged at intervals on the drawstring. The mounting code includes an "L"-shaped base, and an adjusting seat adjustably arranged at one end of the base and forming a clamping area with the base. A cavity for embedding one end of the bead chain is formed on the adjusting seat. A clamping groove for embedding a part of the drawstring located between two beads and communicating with the cavity is formed on the end face of the adjusting seat away from the base. An end cover for covering the cavity is arranged on the adjusting seat.

[0010] A further setting of the present invention is as follows: The adjusting seat is sleeved on one end of the base. A plurality of fastening grooves extending along its length direction are arranged at one end of the base. The adjusting seat is made of plastic. A fastening claw integrally arranged on the adjusting seat is embedded in any one of the fastening grooves. A lifting plate integrally arranged on the fastening claw is deformed to disengage from the fastening groove during the upward lifting process.

[0011] A further setting of the present invention is as follows: During the process of the two tracks gradually approaching from the farthest distance, the folding curtain remains in a state of not interfering with the bead chain.

[0012] A further setting of the present invention is as follows: During the process of the two tracks gradually moving away from the closest distance, the folding curtain remains in a state of interfering with the bead chain. The folding end protruding from one side of the folding curtain abuts against the beads of the bead chain.

[0013] In summary, the present invention has the following beneficial effects:

[0014] 1. A height adjusting member for fixing at any height of the bead chain is provided between the end of the track and the bead chain, and a folding curtain is arranged between the two tracks. Thus, when the fixed height of the two tracks is changed, the folding curtain cloth can be unfolded along with the tracks; ultimately, sunlight can enter from the upper side of the window to increase the brightness, and at the same time, the folding curtain is used to cover the lower side of the window to prevent irradiation on the human body or protect privacy, so as to meet different usage requirements;

[0015] 2. Limit strips for being inserted into the opening limit grooves of the two tracks are respectively arranged at the upper and lower ends of the folding curtain cloth, so that the installation of the folding curtain cloth can be realized;

[0016] 3. The sealing clip is clamped on the bead chain. Thus, by changing the height at which the sealing clip is clamped on the bead chain, the height of the two tracks can be adjusted, so as to realize the adjustment of the up and down height of the folding curtain. By the clamping and fixing method of the sealing clip and making the clamping part of the sealing clip face the indoor side, finally, the effect of simple operation is achieved; at the same time, the sealing clip covers the opening limit groove, which can prevent the limit strip from falling off;

[0017] 4. Anti-slip strips are arranged on the part of the sealing clip for clamping the bead chain, so as to have an anti-slip effect during clamping. When the beads of the bead chain are embedded in the gap between two adjacent anti-slip strips, the clamping area can be increased, thus improving the clamping stability.

[0018] 5. The track is made of PVC material. At this time, the length of the track can be cut according to actual needs, which has the function of facilitating the adjustment of the width of the pleated curtain.

[0019] 6. One end of the bead chain is embedded in the cavity of the adjusting seat, and the drawstring part between two beads is embedded in the card slot for fixation. At this time, the installation height difference between the upper mounting code and the lower mounting code on the same side can be adjusted.

[0020] 7. During the upward lifting process of the lifting plate, the clamping claw can be separated from the clamping groove, so as to change the position of the adjusting seat fixed on the base, thereby realizing the adjustment of the width of the clamping area formed between the base and the adjusting seat, which is convenient for installation.

[0021] 8. During the process of the two tracks gradually approaching, the folding curtain does not interfere with the bead chain. At this time, the smoothness during the height adjustment process of the two tracks can be ensured.

[0022] 9. During the process of the two tracks gradually moving away from the closest distance, the folding curtain remains in a state of interfering with the bead chain. At this time, although the smoothness will be affected due to the interference between the folding curtain and the bead chain when adjusting the height of the track, the folding end protruding from one side of the folding curtain abuts against the beads of the bead chain. The height at which the folding end protruding from one side of the folding curtain abuts against the beads can be manually adjusted, and the beads support the folding curtain, avoiding the situation that the top folding part is loose and the bottom folding part is tight under the action of gravity, and improving the aesthetics during use.

The adjusting seat 12 is sleeved on one end of the base 11, and a plurality of fastening grooves 111 extending along its length direction are arranged at one end of the base 11. The adjusting seat 12 is made of plastic, and a fastening claw 124 embedded in any one of the fastening grooves 111 is integrally arranged on the adjusting seat 12, and a lifting plate 125 that deforms the fastening claw 124 and disengages it from the fastening groove 111 during the upward lifting process is integrally arranged on the fastening claw 124. Figure 3

[0032] As Figure 3 and Figure 4 shown, the bead chain 2 includes a pulling rope 21 and a plurality of beads 22 arranged at intervals on the pulling rope 21. A cavity 121 for embedding one end of the bead chain 2 is formed on the adjusting seat 12, a clamping groove 122 for embedding a part of the pulling rope 21 located between two beads 22 and communicating with the cavity 121 is formed on the end face of the adjusting seat 12 away from the base 11, and an end cover 123 for covering the cavity 121 is arranged on the adjusting seat 12.

[0033] As Figure 3 and Figure 4As shown in the figure, an opening limiting groove 31 extending along the length direction is provided on the track 3, and the opening limiting grooves 31 of the two tracks 3 are close to each other. Limiting strips 41 for plugging into the opening limiting grooves 31 of the two tracks 3 are respectively provided at the upper and lower ends of the folding curtain 4. The two tracks 3 are made of PVC material, the length of the limiting strip 41 is the same as the width of the folding curtain 4, and the limiting strip 41 is also made of PVC material.

[0034] As Figure 3 and Figure 4 shown, the folding curtain 4 is made of fabric and is folded into a continuous zigzag shape.

[0035] As Figure 3 and Figure 4 shown, the height adjusting member 5 is a sealing clip 51 with one end plugged and fixed at the end of the track 3 and used for clamping on the bead chain 2. The sealing clip 51 covers the opening limiting groove 31; and the part of the sealing clip 51 for clamping faces the interior after the folding curtain is installed; at the same time, the part of the sealing clip 51 for clamping the bead chain 2 is integrally provided with anti-slip strips 511 arranged in a row, and the cross-section of the depression formed between adjacent anti-slip strips 511 is arc-shaped to increase the contact area with the beads 22.

[0036] As Figure 1 and 2 shown, at the same time, during the process of the two tracks 3 gradually approaching from the farthest distance, the folding curtain 4 remains in a state where it does not interfere with the bead chain 2.

[0037] Implementation effect: A height adjusting member 5 for fixing at any height of the bead chain 2 is provided between the end of the track 3 and the bead chain 2, and a folding curtain 4 is provided between the two tracks 3. Thus, when the fixed height of the two tracks 3 is changed, the folding curtain can be unfolded along with the track 3; finally, the purpose of allowing sunlight to enter from the upper side of the window to increase the brightness and using the folding curtain 4 to cover the lower side of the window to prevent irradiation of the human body or protect privacy can be achieved to meet different usage requirements.

[0038] Embodiment 2: An up-and-down height adjustable folding curtain, as Figure 5 shown, the difference from Embodiment 1 is that during the process of the two tracks 3 (refer to Figure 1During the process of gradually moving away from the closest distance, the folding curtain 4 remains in a state of interference with the bead chain 2, and the folded end protruding from one side of the folding curtain 4 abuts against the beads 22 of the bead chain 2. At this time, although the smoothness will be affected due to the interference between the folding curtain 4 and the bead chain 2 when adjusting the height of the adjusting track 3, the folded end protruding from one side of the folding curtain 4 abuts against the beads of the bead chain 2, and the height of the folded end protruding from one side of the folding curtain 4 abutting against the beads 22 of the bead chain 2 can be manually adjusted. The folding curtain 4 is supported by the beads 22 to avoid the situation where the top folded part of the folding curtain 4 is loose and the bottom folded part is tight under the action of gravity, and the aesthetics during use is improved. At the same time, because the folding curtain 4 can be deformed, the bead chain 2 will not be deformed due to excessive extrusion of the bead chain 2 during the lifting and lowering of the two tracks 3.
