Description

Technical Field

[0001] This invention relates to the field of curtains, specifically to a fixing structure for Roman blinds, and also to a method for installing curtain fabric based on the fixing structure of Roman blinds. Background Technology

[0002] Roman blinds are a type of curtain decoration, and can be categorized by shape into folding, fan-shaped, and wave-shaped types. Roman blinds create a more intimate and cozy effect and are now commonly used in homes and upscale entertainment and leisure venues such as hotels, enjoying widespread popularity. Roman blinds feature horizontal rods running through the fabric, giving it a crisp and structured look, fully showcasing its texture. Compared to roller blinds, which also have an upward-pulling operation, Roman blinds offer a more layered and sophisticated decorative effect.

[0003] After Roman blinds were introduced to the market, some technical shortcomings gradually became apparent:

[0004] Firstly, the structure lacks stability. Under current technology, the top of the curtain is mainly attached to the bottom of the cover suspended on the building component by Velcro. Although Velcro is convenient, it has poor tensile strength. The curtain can be easily torn off by crosswinds blowing in from outside the window or by children pulling it.

[0005] Secondly, the structure is difficult to install and disassemble. On the one hand, the top of the curtain using existing technology employs a snap-fit ​​structure different from Velcro or is directly sewn onto the cover. While this provides sufficient stability, it makes installation and / or disassembly, as well as washing and / or replacement, difficult. On the other hand, the multiple horizontal rods running through the fabric in the middle of the Roman blind are difficult to install and easily tear the curtain. This is because installing the horizontal rods requires pre-fabricating a sewn fabric ring on the curtain, and then gradually pushing the horizontal rod into the ring from one end. As is well known, the fabric is soft and easily tears during the pushing process. At the same time, the ends of the inserted horizontal rods lack restraint and have the freedom to slide laterally. During the raising and lowering of the curtain and swaying under external disturbances, the horizontal rods easily slip out of the fabric ring and fall off. Furthermore, the counterweights at the bottom of the curtain are generally connected to the curtain by snap-fit ​​or sewn-on methods, which are also difficult to install and disassemble. Summary of the Invention

[0006] In response to the problems raised in the background art, the present invention provides a fixing structure and installation method for Roman blinds, which will be further described below.

[0007] A fixing structure for a Roman blind includes a slot on the cover, with an opening on one side of the slot. An upper locking block is built into the slot, and the upper locking block can be inserted into or removed from the slot through the opening. The curtain fabric is fixed in the slot by the upper locking block.

[0008] Optionally, the cover has a hook at the slot, which deforms into the slot when the upper locking block is engaged. This deformation prevents the upper locking block from sliding out of the slot, thus serving as a limiting mechanism.

[0009] Optionally, there is a gap between the upper card block and the card slot, which is less than the thickness of the curtain fabric. The curtain fabric wraps around the upper card block, along the direction of the gap between the upper card block and the card slot, and fills the gap between the upper card block and the card slot.

[0010] Furthermore, the slot is inclined relative to the vertical curtain, and the bottom is further away from the vertical curtain than the top. This is designed to make it easier to insert the upper locking block into the slot, while increasing the wrap angle of the pull bead on the control head, which can reduce the probability of the pull bead detaching from the control head.

[0011] Furthermore, the upper locking block has a hollow interior. This is intended to reduce the weight of the upper locking block and save manufacturing costs; on the other hand, the hollow interior can serve as a point of force for the finger to rotate the upper locking block out of the slot.

[0012] It also includes a bottom rod hanging at the bottom of the curtain. The top of the bottom rod has an upper groove with an opening, and the side has a side groove extending into the bottom rod. A locking bar is built into the upper groove, and the radius difference between the locking bar and the upper groove is less than the thickness of the curtain. A lower locking block is built into the side groove, and there is a gap between the lower locking block and the side groove wall, which is less than the thickness of the curtain. The bottom of the curtain successively wraps around the locking bar in the upper groove, part of the outer surface of the bottom rod, and the lower locking block in the side groove before exiting the side groove. Under the weight of the lower locking block, the locking bar, and the bottom rod, the curtain experiences friction with each component, and under this friction, it forms a stable whole.

[0013] Optionally, the side groove wall is symmetrically provided with anti-disengagement grooves, and the lower locking block is provided with protruding locking protrusions that fit into the anti-disengagement grooves; the purpose is to prevent the lower locking block from disengaging and sliding out from the side groove through the structure.

[0014] Optionally, the side groove is U-shaped, with a small end and a large end, the opening end of which is the small end, and the lower locking block is locked in the side groove.

[0015] It also includes a crossbar, which is an unclosed tube with a groove. Its inner cavity is provided with a sliding rod. The part of the curtain near the crossbar is folded and located in the inner cavity of the crossbar and wraps around the sliding rod. Both ends of the crossbar are fitted with sleeves, which are provided with a cloth-avoiding groove. The inner wall of the sleeve is provided with a step, and the end face of the crossbar abuts against the surface of the step. The sum of the diameter of the sliding rod and the thickness of the double-layer curtain is greater than the width of the groove of the crossbar.

[0016] Furthermore, a cover is connected to the sleeve, which fits onto the sleeve to make the inside of the sleeve and crossbar invisible to enhance aesthetics and prevent the slide bar from slipping out; the cover is provided with a positioning hole that engages with the slide bar.

[0017] It also relates to a method for installing Roman blinds, including the following steps:

[0018] For the connection between the top of the curtain and the cover, the curtain is first wrapped around the upper clip, and then the bottom of the upper clip, along with the curtain it contacts, is pushed into the clip groove from the opening until the bottom of the upper clip contacts the bottom of the groove. Finally, the end of the upper clip that is still outside the clip groove is pressed into the clip groove.

[0019] To connect the bottom of the curtain to the bottom rod, first wrap the curtain around one end of the clamping bar and insert it into the upper groove from the side. During the pressing process, the clamping bar gradually presses the curtain into the round groove. Then, wrap the curtain around the surface of the bottom rod. Finally, insert the lower clamping block into the side groove until the lower clamping block's protrusion is engaged in the side groove.

[0020] First, place a retainer on the end of the horizontal bar in the middle of the curtain until the end face of the horizontal bar abuts against the stepped surface of the retainer. Wrap the edge of the curtain near the horizontal bar around the sliding rod. Then, pass one end of the sliding rod wrapped with the curtain through the retainer and into the horizontal bar. At this time, the curtain enters the horizontal bar through the fabric avoidance groove. Gradually push the entire sliding rod into the horizontal bar. Finally, place another retainer on the horizontal bar and close the caps of both retainers on the retainers. Position both ends of the sliding rod in the positioning holes of the caps.

[0021] Beneficial effects: Compared with the prior art, the present invention has made structural improvements to the connection between the top of the curtain and the cover, the middle rod insertion, and the bottom connection with the bottom rod, making the Roman blind table of the present invention easy to disassemble without damaging the curtain. The overall practicality and aesthetics are significantly better than existing Roman blinds. Attached Figure Description

Detailed Implementation

[0028] Next, we will combine the appendix Figure 1-5 A specific embodiment of the present invention will be described in detail below.

[0029] Reference Appendix Figure 1-2 A fixing structure for Roman blinds is applied to the cover of Roman blinds for convenient installation or removal of the curtain fabric. It includes a slot 2 located on the cover 1, which is integrally formed by sheet metal cover. There is an opening 3 on the side of the slot, which serves as a channel for the upper locking block 4 to engage or disengage from the slot 2.

[0030] In one embodiment, the cover 1 forms a hook 101 at the slot 2. Its function is that when the upper block 4 is inserted into the slot 2, the upper block 4 squeezes the hook 101 to cause a slight deformation into the slot. This deformation can prevent the upper block 4 from sliding out of the slot, thus playing a limiting role.

[0031] In another embodiment, there is a gap between the upper card block 4 and the card slot wall, which is less than the thickness of the curtain 5. The curtain wraps around the upper card block 4, along the gap between the upper card block and the card slot, and fills the gap between the upper card block and the card slot.

[0032] When installing the curtain fabric onto the housing 1, first wrap the curtain fabric around the upper clamping block. Then, push the bottom of the upper clamping block, along with the curtain fabric it contacts, into the clamping groove through the opening 3 until the bottom of the upper clamping block contacts the bottom of the groove. Finally, press the rounded corner of the top of the upper clamping block, which was previously outside the clamping groove, into the groove. At this point, the curtain fabric is clamped between the upper clamping block and the clamping groove, making the curtain fabric stable under the frictional force between the curtain fabric and the upper clamping block and the clamping groove, as well as the indirect force between the upper clamping block and the clamping groove.

[0033] The slot 2 is inclined relative to the vertical plane, and the bottom is further away from the vertical curtain than the top, which is intended to make it easier to insert the upper locking block 4 into the slot 2; at the same time, it is easy to form a hook 101 at the top of the slot; and considering that the power source for raising and lowering the curtain can be manually pulled by the pull bead 6, for example, in this embodiment, the pull bead and the control head 7 are used to drive the control head to rotate, thereby raising or lowering the curtain. At this time, the inclined slot wall has a guiding effect on the pull bead 6, increasing the wrap angle of the pull bead on the control head, which can reduce the probability of the pull bead detaching from the control head.

[0034] Of course, in a preferred embodiment, while the cover 1 forms a hook 101 at the slot 2, the curtain wraps around the upper card block 4, along the interval between the upper card block and the slot and fills the gap between the upper card block and the slot, so that the upper card block is stabilized by the combined action of the two.

[0035] The upper locking block 4 has a hollow interior, which aims to reduce the weight of the upper locking block and save manufacturing costs. On the other hand, the hollow cavity can serve as a force point for the finger to rotate the upper locking block out of the slot. Simply insert the finger into the upper part of the cavity and apply a pushing force in the direction of the opening 3 to rotate the upper locking block out of the slot.

[0036] In this embodiment, a slot 2 with an opening 3 is integrally formed on the original cover, and the curtain can be fixedly installed on the cover 1 by cooperating with the locking block 4 on the simple component; and disassembly is also convenient, which can be done by applying greater pulling force to the curtain 5, or by directly moving the inner cavity of the locking block 4 to the upper position in the direction of the opening.

[0037] Reference Appendix Figure 1 and 5 A bottom rod 8 for counterweight is hung at the bottom of the curtain. The bottom rod pulls the curtain downwards by its own weight to keep it flat and can maintain stability under external disturbances such as crosswinds. As described in the background art, the bottom rod 8 in the prior art is generally made by sewing a cloth cover onto the curtain to pass through the bottom rod, or by using a clamping mechanism to directly clamp it onto the curtain. However, in this embodiment, based on the purpose of connecting to the top of the curtain and the cover without an independent clamping mechanism, the bottom rod is made of a special-shaped sheet metal part or injection molded part, and is matched with the lower clip 9 to be configured onto the curtain.

[0038] Specifically, the bottom rod 8 has an upper groove 10 with an opening at the top and a side groove 11 extending into the sheet metal bottom rod at the side. A locking bar 12 is built into the upper groove 10, and the radius difference between the locking bar and the upper groove is less than the thickness of the curtain fabric. A lower locking block 9 is built into the side groove, and the distance between the lower locking block and the side groove wall is less than the thickness of the curtain fabric. The free end of the bottom of the curtain fabric first enters the upper groove through the opening on the upper groove, passes around the locking bar, and then exits the upper groove. Then it follows the outer surface of the bottom rod and goes around to the side groove on the other side. After the free end enters the side groove, it wraps around the lower locking block and then exits the side groove. The curtain fabric has friction with each component under the gravity of the lower locking block, the locking bar, and the bottom rod, and forms a stable whole under this friction.

[0039] The side groove 11 has symmetrical anti-disengagement grooves 13 on its groove wall. Correspondingly, the lower locking block 9 has a protruding locking protrusion 14, which fits into the anti-disengagement groove. The purpose is to prevent the lower locking block from disengaging and sliding out of the side groove through the structure. Alternatively, the side groove 11 is U-shaped with a large end and a small end. When the lower locking block 9 is pushed into the side groove, the lower locking block 9 squeezes the opening of the side groove and locks into the side groove, preventing it from disengaging through compression.

[0040] The groove opening of the anti-detachment groove 13 faces the inner cavity of the bottom rod 8, which is designed so that when the lower locking block is installed, the locking protrusion 14 can be locked into the anti-detachment groove with a small deformation, and the cooperation between the locking protrusion and the anti-detachment groove forms a barb structure, which has a better anti-detachment effect.

[0041] During installation, the curtain fabric is first wrapped around the clamping rod 12, and one end is inserted sideways into the upper groove. During the pressing process, the clamping rod gradually presses the curtain fabric into the round groove. Then, the curtain fabric is wrapped around the surface of the bottom rod. Finally, the lower clamping block is inserted into the side groove until the lower clamping block's protrusion is engaged in the side groove. At this point, the curtain fabric is clamped between the lower clamping block and the side groove, ultimately forming a stable whole.

[0042] Reference Appendix Figure 1 and 3 -4. Multiple horizontal rods 15 are threaded through the curtain. A ring is fitted on each horizontal rod. The horizontal rods are connected by a pull line. One end of the pull line is tied to the bottom horizontal rod, and the other end passes through the ring and is hung on the rotating shaft inside the housing. As the rotating shaft rotates, the pull line is wound up or released to achieve the purpose of opening or closing the curtain. The method of raising and lowering the curtain is a conventional technical means, which will not be described in detail in this embodiment.

[0043] In this embodiment, in order to achieve the purpose of convenient installation and removal of the curtain together with the cover and the bottom rod, and at the same time to overcome the risks of the existing horizontal rod easily tearing the curtain and easily slipping out and falling off after being inserted, as described in the background art, this embodiment changes the existing method of inserting the horizontal rod.

[0044] Specifically, the crossbar 15 is an open tube with a groove, and its inner cavity is provided with a sliding rod 16. The part of the curtain near the crossbar is folded and enters the inner cavity of the crossbar through the groove and wraps around the sliding rod 16. The two ends of the crossbar 15 are fitted with a retaining sleeve 17, which has a cloth-avoiding groove 18. The inner wall of the retaining sleeve has a step 19. When the retaining sleeve is fitted on the end of the crossbar, the end face of the crossbar abuts against the step surface. The sum of the diameter of the sliding rod and the thickness of the double-layer curtain is greater than the width of the groove of the crossbar 15, which is intended to prevent the sliding rod from falling.

[0045] A cover 20 is connected to the sleeve 17. The cover can be used to close the sleeve, making the inside of the sleeve and the crossbar invisible to enhance the aesthetics, and also to limit the sliding rod to prevent it from sliding out.

[0046] Furthermore, the cover 20 is provided with a positioning hole 21 for engaging with the slide rod.

[0047] The method for inserting the crossbar in this embodiment is as follows: First, a retainer 17 is fitted onto the end of the crossbar until the end face of the crossbar abuts against the stepped surface of the retainer; then, the edge of the curtain near the crossbar is wrapped around the slide bar; next, one end of the slide bar 16 wrapped with the curtain is passed through the retainer and inserted into the crossbar 15, at which point the curtain enters the crossbar through the fabric groove; thereafter, the slide bar is gradually pushed into the crossbar; finally, another retainer is fitted onto the crossbar, and the caps 20 of the two retainers are closed on the retainers, with both ends of the slide bar positioned in the positioning holes of the caps.

[0048] In this rod-threading method, the diameter of the sliding rod can be smaller than the inner diameter of the horizontal rod. The curtain fabric has the freedom to twist and slide during rod threading, preventing tearing. Furthermore, this method allows for rod threading at any position on the curtain fabric, offering high adaptability. When threading a rod onto another curtain fabric with a pre-fabricated cover, the method is the same as described above, except that the threading position remains constant each time, and the cover is pre-pressed into the horizontal tube.

[0049] As can be seen from the above description, the Roman blind of the present invention has made improvements to the connection between the top of the blind and the cover, the middle rod insertion, and the bottom connection with the bottom rod, which are completely different from the existing connection structures, making the Roman blind of the present invention have a significantly different installation method.

[0050] The installation method of the Roman blind of the present invention includes the following steps:

[0051] For the connection between the top of the curtain and the cover, the curtain is first wrapped around the upper clip, and then the bottom of the upper clip, along with the curtain it contacts, is pushed into the clip groove from the opening until the bottom of the upper clip contacts the bottom of the groove. Finally, the end of the upper clip that is still outside the clip groove is pressed into the clip groove.

[0052] To connect the bottom of the curtain to the bottom rod, first wrap the curtain around one end of the clamping bar and insert it into the upper groove from the side. During the pressing process, the clamping bar gradually presses the curtain into the round groove. Then, wrap the curtain around the surface of the bottom rod. Finally, insert the lower clamping block into the side groove until the lower clamping block's protrusion is engaged in the side groove.

[0053] First, place a retainer on the end of the horizontal bar in the middle of the curtain until the end face of the horizontal bar abuts against the stepped surface of the retainer. Wrap the edge of the curtain near the horizontal bar around the sliding rod. Then, pass one end of the sliding rod wrapped with the curtain through the retainer and into the horizontal bar. At this time, the curtain enters the horizontal bar through the fabric avoidance groove. Gradually push the entire sliding rod into the horizontal bar. Finally, place another retainer on the horizontal bar and close the caps of both retainers on the retainers. Position both ends of the sliding rod in the positioning holes of the caps.

[0054] It should be noted that there is no absolute order among the three steps in the above installation method; they can be completed independently or simultaneously in any order.

[0055] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
