Description

Technical Field

[0001] This invention relates to the field of home furnishing technology, specifically to a sewing-free modular curtain assembly. Background Technology

[0002] Existing curtain installation methods typically rely on professional sewing techniques. After purchasing the fabric, users must go through complex processes such as cutting, hemming, high-temperature setting, and sewing hooks before installation. This not only increases costs but also limits users' DIY freedom. Traditional curtains are made to a fixed height. If the window height changes (e.g., from 2 meters to 1.8 meters), the original curtains often become unusable or require re-sewing. In terms of hanging methods, Roman rods (through-rod type) and top-mounted tracks (hook type) usually require different accessories, which are mostly sewn onto the curtain, making it difficult to achieve quick assembly / disassembly and secure hanging. Therefore, there is an urgent need for a curtain installation structure that can adapt to windows of different heights, requires no sewing, and can be quickly adapted to Roman rods or tracks using the fasteners described in this application.

[0017] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0018] Furthermore, in this invention, the use of terms such as "first" and "second" is for descriptive purposes only and does not specifically refer to any order or sequence, nor is it intended to limit the invention. They are merely used to distinguish components or operations described using the same technical terms and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions and features of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. If a combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0019] The present invention provides the following embodiments. Example 1: This embodiment of the invention provides a sewing-free modular curtain assembly, such as... Figures 1-4 As shown, the curtain fabric 19 and several fasteners are included. The curtain fabric 19 is folded and locked to different heights by several fasteners, and the curtain fabric 19 can be quickly adapted to Roman rods or rails by several fasteners. The fasteners include caps 1. The front of the caps 1 is equipped with a piercing needle 7 through an adjustment mechanism. The front side of the piercing needle 7 is a needle tip, and the rear side of the piercing needle 7 is a round rod. The piercing needle 7 is used to pass through the folded multi-layer curtain fabric 19. The front side of the round rod of the piercing needle 7 is provided with an annular groove 8. The annular groove 8 is detachably engaged with a limiting clip. An adjustment hook is detachably installed at the rear end of the caps 1.

[0020] The working principle of the above technical solution is as follows: Curtain fabric 19 is made of fabric with lace trim, retaining the original edge without sewing. If the window is too low and curtain fabric 19 is too high, first fold the top of curtain fabric 19. If the hanging method is a Roman rod: pass the folded top of curtain fabric 19 directly through the Roman rod, and then use multiple fasteners below or above the Roman rod to lock the folded part to prevent the folded part of curtain fabric 19 from slipping off. If the hanging method is a top track: after folding the top of curtain fabric 19, use multiple fasteners to lock the folded part, and then hang the hooks on the fasteners into the sliding rings of the top track. During the installation of the fasteners and curtain fabric 19, the piercing needle 7 is passed through the folded curtain fabric 19. Then, the limiting clip is inserted into the piercing needle 7 and pushed towards the cap 1 until the limiting clip moves to the corresponding position in the annular groove 8, thus engaging the limiting clip with the annular groove 8. This completes the engagement between the limiting clip and the piercing needle 7, fixing the folded curtain fabric 19 between the limiting clip and the cap 1, shaping the folded curtain fabric 19. When it is necessary to wash or replace the curtain fabric 19, the limiting clip is then engaged with the annular groove... 8. Disengage the fastener and pull it away from the cap 1 to separate the cap 1 and its connected piercing needle 7 from the fastener. The folded curtain fabric 19 will then unfold again for easy cleaning. If the curtain fabric 19 needs to be replaced, the removed fastener can be used for the new curtain fabric 19. The quick-release fastener can lock the folded part of the curtain fabric 19, making it suitable for windows of different heights without sewing. The curtain fabric 19 can also be quickly adapted to Roman rods or tracks using the fasteners of this application.

[0021] Example 2: Based on Example 1, as follows Figures 1-6 As shown, the cap 1 has a mounting hole 2 at the rear end of its center, a mounting hole 3 at the middle of its center, and a mounting hole 33 at the front end of its center. The mounting holes 33, 23, and 2 are connected front to back. The diameter of the mounting hole 33 is larger than that of the mounting hole 23, and the diameter of the mounting hole 23 is larger than that of the mounting hole 2. The left and right sides of the mounting hole 23 are symmetrically connected with guide grooves 4. The cap 1 has a positioning hole 5 eccentrically located behind the mounting hole 33. The adjustment mechanism includes a rotating rod 10. The central cylindrical section of the rotating rod 10 is rotatably connected to the mounting hole 2. The front threaded section of the rotating rod 10 is threadedly connected to the threaded hole on the rear side of the round rod of the puncture needle 7. Guide blocks 9 are symmetrically provided on the left and right sides of the round rod of the puncture needle 7. The guide blocks 9 on the left and right sides are slidably connected to the guide grooves 4 on the left and right sides respectively. A limit ring 6 is correspondingly fitted in the mounting hole 33. A through hole 1 for the round rod of the puncture needle 7 to pass through is provided at the center of the limit ring 6.

[0022] The working principle of the above technical solution is as follows: Insert the round rod of the puncture needle 7 into the second mounting hole 3. Set guide blocks 9 on both sides of the round rod of the puncture needle 7. The guide blocks 9 slide along the guide groove 4, so that the round rod of the puncture needle 7 slides along the second mounting hole 3. Rotate the rotating rod 10 in the first mounting hole 2. The rotating rod 10 is threadedly connected to the threaded hole on the rear side of the round rod of the puncture needle 7. When the rotating rod 10 is rotated, it can drive the puncture needle 7 to slide along the guide groove 4. By driving the puncture needle 7 to move back and forth, the distance between the annular groove 8 and the cap 1 in the front and back direction can be adjusted, which is convenient for curtain fabrics 19 of different thicknesses after folding. The setting of the limiting ring 6 is used to block the guide groove 4 and limit the front and back movement of the round rod of the puncture needle 7 and the guide block 9 connected to it.

[0023] Example 3: Based on Example 2, such as Figures 2-5 As shown, the adjusting hook includes a positioning base block 12, and a hook base block 20 is movably provided at the upper end of the positioning base block 12. The hook base block 20 is fixedly connected to the hook 18. A countersunk hole is provided in the middle of the positioning base block 12. The countersunk hole corresponds to the rear head of the positioning rod 13. The front tail of the positioning rod 13 passes through the countersunk hole and the positioning hole 5. The front tail of the positioning rod 13 is provided with a locking hole. The locking hole corresponds to the cotter pin 43. The cotter pin 43 contacts the front end of the limiting ring 6. The lower side of the positioning base block 12 is provided with a fixing hole 41, and an internal toothed ring 17 is fixedly provided in the fixing hole 41. The internal toothed ring 17 meshes with the positioning tooth 16. The positioning tooth 16 is fixedly connected to the rear end of the rotating rod 10. A spring 11 is provided between the rear ends of the positioning base block 12 and the cap 1. The spring 11 is sleeved on the middle cylindrical section of the rotating rod 10. The upper side of the positioning base block 12 is provided with positioning hole 2 42, and the hook base block 20 is provided with a number of positioning holes 3 evenly spaced in the vertical direction. Positioning hole 2 42 and any positioning hole 3 are correspondingly matched with positioning post 14. A connecting plate 15 is fixedly provided between the rear end of positioning post 14 and positioning rod 13.

[0024] The working principle of the above technical solution is as follows: If the suspension method is a top-mounted track: First, fit spring 11 onto the rotating rod 10. Then, insert the fixing hole 41 of the positioning base block 12 into the rotating rod 10. After the positioning base block 12 contacts spring 11, the internal gear ring 17 meshes with the positioning tooth 16. At this time, the rotating rod 10 connected by the positioning tooth 16 cannot rotate. Then, insert the positioning rod 13 into the countersunk hole, so that the head of the positioning rod 13 corresponds to the countersunk hole. The diameter of the rear head of the positioning rod 13 is larger than the diameter of the front tail of the positioning rod 13. At this time, the front tail of the positioning rod 13 passes through the countersunk hole and the positioning hole 5, and inserts the cotter pin 43 into the locking hole, so that the cotter pin 43 contacts the front end of the limiting ring 6. The positioning rod 13 holds the positioning base block 12 and the cap The cap 1 is connected so that the positioning base block 12 cannot move backward and separate from the cap 1, thus preventing the positioning base block 12 from separating from the cap 1. The positioning rod 13 guides the forward movement of the positioning base block 12, preventing the positioning base block 12 and the cap 1 from deflecting relative to each other. When controlling the puncture needle 7 to move back and forth, the positioning base block 12 is pressed. At this time, the positioning base block 12 moves forward and compresses the spring 11 until the positioning tooth 16 and the inner tooth ring 17 disengage. At this time, the positioning tooth 16 can rotate freely, thereby controlling the rotating rod 10 to rotate freely. If the rotating rod 10 is kept fixed, the positioning base block 12 is released, and the positioning base block 12 is driven to return to its original position under the elastic action of the spring 11. The hook base block 20 can move up and down along the positioning base block 12, which is equivalent to adjusting the telescopic length of the hook base block 20. Several positioning holes 3 are set on the hook base block 20 in the vertical direction. The hook base block 20 can adjust the position of the positioning holes 3 by moving. After the positioning hole 22 and the target positioning hole 3 are connected, the positioning pin 14 is inserted into the positioning hole 22 and the target positioning hole 3. At this time, the hook base block 20 cannot move along the positioning base block 12. The length of the hook base block 20 and the positioning base block 12 is adjusted. The hook base block 20 is connected to the hook 18. The hook 18 can be hooked into the sliding ring of the top mounting track. The setting of the connecting plate 15 connects the positioning rod 13 and the positioning pin 14 into one piece. After the positioning base block 12 and the cap 1 are connected, the positioning pin 14 is also fixed in the positioning hole 22 and the target positioning hole 3. That is, when the hook is installed on the cap 1, its length is also adjusted synchronously. If the hanging method is a Roman rod: At this time, there is no need to adjust the hook. Take out the cotter pin (43) from the locking hole, then pull out the positioning hole 13 from the countersunk hole and positioning hole 5, and remove the positioning base block 12 and spring 11 from the rotating rod 10. The disassembly of the adjustment hook is completed. Only the cap 1, the piercing needle 7 and the limit clip are left. Lock the folding part below or above the Roman rod to prevent the curtain fabric 19 at the folding part from slipping off.

[0025] Example 4: Based on Example 1, as follows Figure 2 , Figures 7-11As shown, the limiting clip includes a contact ring 21, with a through hole 22 penetrating through the center of the contact ring 21. A rotating ring 23 is rotatably provided at the front end of the contact ring 21. A through hole 32 is provided at the front end of the rotating ring 23. An installation groove 26 is provided at the rear end of the rotating ring 23. The through hole 32 and the installation groove 26 are connected front to back. A fixing ring 24 is fixedly provided in the through hole 32 and is fixedly connected to the front end of the contact ring 21. A through hole 44 is provided at the front end of the fixing ring 24. A fixing groove 35 is provided at the rear end of the fixing ring 24. The through hole 44 and the fixing groove 35 are connected front to back. A decorative block 25 is fixedly connected to the front end of the fixing ring 24. A through hole 5 40 is penetrating through the center of the decorative block 25. The diameter of the second through hole 22 is the same as that of the round rod of the puncture needle 7. The diameter of the mounting groove 26 is larger than that of the third through hole 32. The diameter of the fixing groove 35 is larger than that of the fourth through hole 34. The second through hole 22, the fourth through hole 34 and the fifth through hole 40 are for the puncture needle 7 to pass through.

[0026] The working principle of the above technical solution is as follows: When the limiting clip is connected to the puncture needle 7, the tip of the puncture needle 7 first contacts the second through hole 22 on the contact ring 21, which facilitates the alignment of the puncture needle 7 with the second through hole 22. As the puncture needle 7 gradually penetrates the second through hole 22, since the diameter of the second through hole 22 and the round rod of the puncture needle 7 are the same, the puncture needle 7 and the contact ring 21 complete the positioning engagement. The two can only move back and forth and will not deflect. As the puncture needle 7 continues to move along the second through hole 22, the puncture needle 7 can finally pass through the second through hole 22, the fourth through hole 34 and the fifth through hole 40, so that the contact ring 21 contacts the curtain fabric 19. The cap 1 and the contact ring 21 clamp the two ends of the folded curtain fabric 19 to prevent the curtain fabric 19 at the fold from slipping off.

[0027] Example 5: Based on Example 4, such as Figures 7-11 As shown, a plurality of fixing blocks 28 are evenly distributed around the outer circumference of the fixing ring 24, and the fixing ring 24 is fixedly connected to the fixing blocks 28. A plurality of arc-shaped blocks 27 are evenly distributed around the circumference of the mounting groove 26, and the mounting groove 26 is fixedly connected to the arc-shaped blocks 27. The plurality of fixing blocks 28 and the plurality of arc-shaped blocks 27 are connected one-to-one by a plurality of springs 29. The plurality of arc-shaped blocks 27 are slidably connected one-to-one with a plurality of guide rods 30. The plurality of guide rods 30 are evenly distributed around the side end of the fixing ring 24, and the guide rods 30 pass through the side end of the fixing ring 24 and are fixedly connected to the retaining bead 31. The retaining bead 31 is correspondingly engaged with the annular retaining groove 8. The rotating ring 23 is evenly distributed with a number of elastic telescopic blocks 37. The elastic telescopic blocks 37 are fixedly connected to the connecting rod 38. The connecting rod 38 is rotatably connected to the roller 39. The roller 39 is fixedly connected to the limiting block 36. The roller 39 makes rolling contact with the outside of the decorative block 25. The limiting block 36 and the decorative block 25 have a gap in the front-back direction.

[0028] The working principle of the above technical solution is as follows: Before the puncture needle 7 passes through through holes 22, 34, and 40, the rotating ring 23 needs to be turned. When the rotating ring 23 rotates, it drives the arc-shaped block 27 to rotate. The rotation of the arc-shaped block 27 pulls the guide rod 30 to slide, compressing the spring 29. Because the sliding surfaces of the arc-shaped block 27 and the guide rod 30 are arc-shaped, they can pull the guide rod 30 away from the fixed ring 24. The guide rod 30 drives the retaining bead 31 to move, so that the retaining bead 31 no longer corresponds to through hole 34. That is, the retaining bead 31 will not interfere with the insertion and engagement of the puncture needle 7 with through holes 22, 34, and 40. Furthermore, when the rotating ring 23 is turned, it drives the elastic telescopic block 37 to rotate. The elastic telescopic block 37 drives the roller through the connecting rod 38. When the rotating ring 23 is not turned, the roller 39 rolls along the outside of the decorative block 25. Several arc-shaped protrusions are provided on the outer circumference of the decorative block 25 (so that the diameter of the decorative block 25 is variable, and the symmetry also plays an aesthetic role). When the rotating ring 23 is not turned, the roller 39 is located at the small end of the diameter of the decorative block 25. As the rotating ring 23 rotates, the roller 39 rolls along the arc-shaped protrusions (gradually moving towards the large end of the diameter of the decorative block 25). The roller 39 drives the limiting block 36 to move, so that the distance between the limiting block 36 and the center of the through hole 40 gradually increases. The elastic telescopic block 37 is stretched. This process is equivalent to the opening of several circumferentially distributed limiting blocks 36, so that the decorative parts (decorative paper or decorative cloth) corresponding to the curtain fabric 19 can be placed on the end face of the decorative block 25 away from the cap 1. When the annular groove 8 on the puncture needle 7 moves back and forth to the corresponding position of the retaining bead 31, the rotating ring 23 is released. Under the elastic action of the second spring 29, the rotating ring 23 rotates in the opposite direction to return to its original position. The rotating ring 23 drives the arc block 27 to rotate in the opposite direction, and the arc block 27 drives the guide rod 30 to slide in the opposite direction. The guide rod 30 drives the retaining bead 31 into the annular groove 8, so that the puncture needle 7 and the limiting clip are engaged. When the rotating ring 23 rotates in the opposite direction, it simultaneously drives the elastic telescopic block 37 to rotate in the opposite direction. The roller 39 rolls in the opposite direction along the outside of the decorative block 25. Under the elastic action of the elastic telescopic block 37, the roller 39 can always be driven to rotate in the opposite direction. Adhering to the outside of the decorative block 25, during this process, the distance between the limiting block 36 and the center of the through hole 40 gradually decreases, which is equivalent to the tightening of several circumferentially distributed limiting blocks 36. The limiting blocks 36 and the decorative block 25 are separated in the front-back direction. The tightening of several limiting blocks 36 presses the decorative piece between the end face of the decorative block 25 and the limiting blocks 36. The shape of the limiting block 36 can be set to the shape of a flower, or it can be set to other shapes that are suitable for the curtain fabric 19, further increasing the aesthetic effect of the end face area of ​​the decorative block 25, and avoiding the limiting clip of this application from conflicting with the style of the curtain fabric 19, thus affecting the overall aesthetic effect of the curtain fabric 19. When disassembling the puncture needle 7 and the limiting clip, simply rotate the rotating ring 23 again to make the retaining bead 31 leave the annular groove 8, and then pull the limiting clip away from the puncture needle 7 to remove the limiting clip. The operation is convenient and quick.

[0029] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
