Description

Technical Field

[0001] This utility model relates to the field of windproof roller shutter technology, specifically to a side rail structure and a windproof roller shutter including the side rail structure. Background Technology

[0002] With the development and maturation of windproof roller blind technology, windproof roller blinds are being used in more and more occasions. The main structural principle of windproof roller blinds is similar to that of indoor window covering roller blinds. However, windproof roller blinds use special accessory construction and processing technology to effectively integrate the curtain fabric and various accessories into a whole. The fabric is rolled up in the cover box. Driven by the motor and counterweighted by the lower rail, the two sides move up and down in the fabric guide components of the side rail, thus achieving wind resistance.

[0003] However, existing windproof roller blinds generally only have a rubber strip in the fabric guide groove of the side rail body to fix the zipper. Since the rubber strip is made of PVC, when the side rail body is exposed to the sun for a long time at high temperatures, the PVC rubber strip is easy to soften. When the fabric is resisting wind pressure, the rubber strip is easily opened due to the large tension on it, which in turn causes the zipper to fall out of the groove, resulting in poor wind resistance. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model proposes a side rail structure and a windproof roller shutter including the side rail structure, which can enhance the wind resistance of the windproof roller shutter.

[0005] The technical solution of this utility model is implemented as follows:

[0006] On one hand, the present invention proposes a side rail structure, including a side rail body and a fabric guiding assembly. The side rail body has a fabric guiding windproof and anti-detachment groove, and the fabric guiding assembly is installed in the fabric guiding windproof and anti-detachment groove. The fabric guiding assembly includes an adhesive strip, a guide member, and a connector. The middle part of the guide member extends outward to form a first limiting groove that matches the size of the adhesive strip, and the adhesive strip is installed in the first limiting groove. The adhesive strip has a second limiting groove for placing the connector, and the connector is installed in the second limiting groove, with one end extending out of the adhesive strip and the guide member in sequence and then connecting to the fabric.

[0007] Preferably, grooves are formed on both sides of the fabric outlet of the first limiting groove, and limiting strips are formed on the adhesive strips corresponding to the positions of the grooves, with the limiting strips being confined within the grooves.

[0008] Preferably, the connector is a T-shaped zipper.

[0009] Preferably, the connector includes a steel strip and a fabric layer wrapped around the steel strip. The steel strip is located in the second limiting groove. After the fabric layer wraps around the steel strip, it extends out of the rubber strip and the guide in sequence and connects with the fabric.

[0010] Preferably, the fabric guiding assembly further includes a fabric guiding component disposed at the starting end of the guide member, the fabric guiding component having an arc-shaped inlet for guiding the fabric in, and the fabric connected at the outlet of the connector being located below the arc-shaped inlet.

[0011] Preferably, the guide member is provided with a plurality of fourth limiting grooves, and one end of the guide material is provided with a plurality of limiting blocks corresponding to the fourth limiting grooves. The limiting blocks are inserted into the fourth limiting grooves to connect the guide material with the guide member.

[0012] Preferably, it also includes an elastic element extending along the length of the side rail body, and the side rail body is provided with a third limiting groove on both sides of the rubber strip for installing the elastic element, and the third limiting groove communicates with the fabric guiding windproof and anti-slip groove.

[0013] Preferably, the side rail body includes a main rail component and a secondary rail component. The secondary rail component is fixed to the main rail component by a detachable connector, and the main rail component and the secondary rail component form the fabric guiding windproof and anti-slip groove.

[0014] Preferably, the main rail component has a connecting hole adapted to the connector, the auxiliary rail component has a mounting portion that abuts against the end of the connecting hole, and the connector passes through the mounting portion into the connecting hole.

[0015] On the other hand, this utility model also provides a windproof roller shutter, including fabric, top cover, lower rail structure and the above-mentioned side rail structure. The two side rail structures are respectively connected to the bottom two sides of the top cover. The two ends of the lower rail structure are movably connected to the side rail structure through the lower rail end cap. The starting end of the fabric is located inside the top cover, and the two sides slide through the side rail structure, and the end can be connected to the lower rail structure.

[0016] Compared with the prior art, the present invention has the following advantages: The fabric guiding component in the edge rail structure of the present invention includes a rubber strip, a guide member and a connector. By installing the rubber strip in the first limiting groove in the guide member that matches the size of the rubber strip, the aluminum alloy guide member can protect the rubber strip by wrapping it. When resisting wind, it avoids the rubber strip from cracking or opening due to thermal expansion and contraction, which would cause the connector connecting the fabric to fall out of the groove. Thus, the edge rail structure of the present invention has a stronger wind resistance effect. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

Furthermore, the terms "first," "second," "third," and "fourth," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0027] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0028] See Figures 1-6 This utility model discloses a side rail structure, including a side rail body 1 and a fabric guiding component 2. The side rail body 1 has a fabric guiding windproof and anti-detachment groove 103, and the fabric guiding component 2 is installed in the fabric guiding windproof and anti-detachment groove 103. The fabric guiding component 2 includes an adhesive strip 201, a guide member 202, and a connector 204. The middle part of the guide member 202 extends outward to form a first limiting groove 2021 that matches the size of the adhesive strip 201, and the adhesive strip 201 is installed in the first limiting groove 2021. The adhesive strip has a second limiting groove 2011 for placing the connector, and the connector 204 is installed in the second limiting groove 2011, with one end extending out of the adhesive strip 201 and the guide member 202 in sequence and then connecting to the fabric 5.

[0029] In this embodiment, a fabric guiding component 2 is provided inside the side rail body 1. The fabric guiding component 2 includes an adhesive strip 201, a guide member 202, and a connector. The guide member 202 is provided with a first limiting groove 2021 for limiting the adhesive strip 201. The size of the first limiting groove 2021 matches the size of the adhesive strip 201 so as to just accommodate and wrap the adhesive strip 201, thereby protecting the adhesive strip 201. When the side rail body 1 is continuously exposed to high temperatures from the sun, since the adhesive strip 201 is well protected in the first limiting groove 2021, the adhesive strip 201 is prevented from cracking or opening due to thermal expansion and contraction when the fabric is windproof, thus preventing the connector 204 connecting the fabric from coming out of the groove, which greatly improves the wind resistance of the side rail body 1.

[0030] Furthermore, the adhesive strip 201 in this application is made of PVC. By setting the adhesive strip 201 in the first limiting groove 2021 of the guide member 2012 limiting strip 202, and since the connector 204 is installed in the second limiting groove 2011 of the adhesive strip 201, noise caused by friction between the connector 204 and the adhesive strip 201 is avoided when the windproof roller shutter is raised and lowered, thus improving the user experience.

[0031] Furthermore, such as Figure 2 and Figure 4 As shown, grooves 2022 are formed on both sides of the fabric outlet of the first limiting groove 2021, and limiting strips are formed on the adhesive strip 201 corresponding to the positions of the grooves 2022, with the limiting strips confined within the grooves 2022. In this embodiment, by setting grooves 2022 on both sides of the fabric outlet of the first limiting groove 2021, the adhesive strip 201 is better confined within the first limiting groove 2021, preventing the adhesive strip 201 from detaching from the first limiting groove 2021 due to thermal expansion and contraction. Even when the fabric is subjected to strong winds, the adhesive strip 201 will not detach from the groove due to cracking or opening.

[0032] In one embodiment, such as Figure 3 and Figure 4 As shown, the connector 204 is a T-shaped zipper, wherein the T-shaped head of the T-shaped zipper is located in the second limiting groove 2011 of the adhesive strip 201 to limit the T-shaped zipper, and the other end of the T-shaped zipper is connected to the fabric.

[0033] In another embodiment, such as Figure 1 and Figure 2 As shown, the connector 204 includes a steel strip and a fabric layer wrapped around the steel strip. The steel strip is located within the second limiting groove 2011. After the fabric layer wraps around the steel strip, it extends sequentially through the adhesive strip 201, the guide 2012 limiting strip, and then connects to the fabric. The fabric and the steel strip can be connected by high-temperature fusion. In this embodiment, because the thickness of the steel strip is much thinner than that of the zipper, when the fabric is rolled up, the thickness of the steel strip after rolling up on the shaft is similar to the thickness of the fabric after rolling up. This results in no significant height difference between the overlapping positions of the steel strips at both ends of the shaft and the overlapping position of the fabric in the middle, preventing the fabric from having a wavy or wrinkled feel. This ensures that the fabric has good flatness and no wrinkles when the user opens the windproof roller blind.

[0034] Furthermore, the width of the steel strip can preferably be 4-6mm. When the fabric is laid down, since the size of the steel strip within the second limiting groove 2011 is less than 1mm, the steel strip has sufficient width to resist wind pressure, and will not derail even if the wind force is strong.

[0035] In this embodiment, the steel strip can be made of stainless steel sheet, which makes the steel strip thinner and lighter, so that when the fabric is recycled, the height of the steel strip after overlapping is basically the same as the height of the fabric after overlapping, and the fabric is smoother.

[0036] Furthermore, such as Figure 5 and Figure 6 As shown, the fabric guiding assembly 2 further includes a fabric guiding component 203 disposed at the starting end of the guide member 202. The fabric guiding component 203 has an arc-shaped inlet 2031 for guiding the fabric 5 into the guide member 202. The fabric connected to the outlet of the connector 204 is located below the arc-shaped inlet 2031. In this embodiment, by providing a fabric guiding component 203 for guiding the guide member 202 at its starting end, and providing an arc-shaped inlet 2031 on the fabric guiding component 203, the fabric 5 can be guided into the side rail body 1 more conveniently to open the fabric 5, and the fabric 5 can also be flattened.

[0037] Specifically, the guide member 202 is provided with a plurality of fourth limiting grooves 2023, and one end of the guide material member 203 is provided with a plurality of limiting blocks 2032 corresponding to the fourth limiting grooves 2023. The limiting blocks 2032 are inserted into the fourth limiting grooves 2023 to connect the guide material member 203 with the guide member 202. In this embodiment, the limiting blocks 2032 are engaged in the fourth limiting grooves 2023, thereby achieving a detachable connection between the guide material member 203 and the guide member 202.

[0038] In this embodiment, the side rail structure also includes an elastic member 3 extending along the length of the side rail body 1. The side rail body 1 also has third limiting grooves 104 on both sides of the rubber strip 201 for mounting the elastic member 3. The third limiting grooves 104 communicate with the fabric guiding windproof and anti-detachment groove 103. The two opposite sides of the elastic member 3 abut against the guide member 202 and the side of the side rail body 1 closest to the fabric 5, respectively. When there is a strong wind, the fabric 5 will gather towards the center when the wind blows. Due to the force of the fabric 5 on the first limiting groove 2021, the bottom of the fabric guiding assembly 2 will directly impact the fabric guiding windproof and anti-detachment groove 103. Therefore, in this invention, elastic members 3 are provided at both the upper and lower ends of the fabric guiding assembly 2 and between the fabric guiding windproof and anti-detachment groove 103. Under the rebound action of the elastic members 3, the fabric 5 can be prevented from gathering towards the center and causing wrinkles, and the fabric guiding assembly 2 can be prevented from directly impacting the mounting groove and generating noise.

[0039] The elastic element 3 is preferably a long strip of sponge pad, because the long strip of sponge pad is flexible and has better resilience, resulting in better noise reduction. Of course, the elastic element 3 can also be made of PVC material or other elastic materials with elastic properties, and this utility model does not impose any restrictions.

[0040] Specifically, the side rail body 1 includes a main rail component 101 and a secondary rail component 102. The secondary rail component 102 is fixed to the main rail component 101 by a detachable fastener 6. The fabric guiding windproof and anti-detachment groove 103 is formed between the main rail component 101 and the secondary rail component 102. In this embodiment, the main rail component 101 and the secondary rail component 102 are detachably connected to facilitate the installation of the side rail. During installation, the main rail component 101 is first fixed, then the adhesive strip 201 is inserted into the first limiting groove 2021 of the guide component 202 and then into the main rail component 101, and finally the secondary rail component 102 is installed, making installation convenient.

[0041] Preferably, the main rail component 101 is provided with a connecting hole 1011 adapted to the fastener 6, and the auxiliary rail component 102 is provided with a mounting portion 1021 that abuts against the end of the connecting hole 1011. The fastener 6 passes through the mounting portion 1021 and is installed in the connecting hole 1011. The fastener 6 is a fixing bolt, and the connecting hole 1011 has an internal thread adapted to the thread of the fixing bolt. After the fixing bolt passes through the mounting portion 1021, the internal thread of the connecting hole 1011 engages with the thread of the fixing bolt, allowing the main rail component 101 and the auxiliary rail component 102 to be tightly connected. Furthermore, the threaded engagement simplifies operation, facilitates assembly and disassembly, and greatly reduces the difficulty of assembling and disassembling the side rail.

[0042] To prevent the fastener 6 from being exposed on the outer wall of the sub-rail member 102, a decorative cover 4 for covering the fastener 6 can be provided on the sub-rail member 102 outside the mounting part 1021. Alternatively, the decorative cover 4 can be replaced with a lampshade, and an LED light can be installed in the space between the decorative cover 4 and the fastener 6, which can serve both as lighting and create a more comfortable environment for the user.

[0043] On the other hand, this utility model also provides a windproof roller shutter, including fabric 5, top cover, lower rail structure and the above-mentioned side rail structure. The two side rail structures are respectively connected to the bottom two sides of the top cover. The two ends of the lower rail structure are movably connected to the side rail structure through the lower rail end cap. The starting end of the fabric 5 is located inside the top cover, and the two sides slide through the side rail structure, and the end can be connected to the lower rail structure.

[0044] In summary, the fabric guiding component in the edge rail structure of this utility model includes a rubber strip, a guide member, and a connector. By installing the rubber strip in the first limiting groove in the guide member that matches the size of the rubber strip, the aluminum alloy guide member can protect the rubber strip by wrapping it. During wind resistance, it prevents the rubber strip from cracking or opening due to thermal expansion and contraction, which could cause the connector connecting the fabric to come out of the groove. This makes the edge rail structure of this utility model have a stronger wind resistance effect.
