A new type of windproof roller shutter conceals window screens

Abstract

A novel windproof roller shutter concealed screen window is characterized by comprising a pressing structure, with power structures at both ends of the pressing structure connected to profiles, a screen below the pressing structure, a clamping structure below the screen, windproof structures on both sides of the screen, and the windproof structures connected to the profiles. The profiles are connected by a self-locking structure. By replacing the traditional return spring with a disc spring structure, and using two disc springs instead of one tension spring, the force on both sides of the roller shaft is evenly distributed, improving the durability and reliability of the device. By adopting a π-shaped pressing structure, the pressure cap and screen are pressed into the pressing groove, ensuring the flatness of the screen and the firmness of the connection. By inserting the fork-shaped structure of the windproof component into the slide rail, damage to the screen window can be avoided when the wind is too strong. The C-shaped clamping structure can effectively fix the screen to prevent it from falling off. The self-locking device enables nail-free and quick installation.

Description

Technical Field

[0001] This invention relates to the field of invisible screen technology, and in particular to a novel windproof roller blind concealed screen. Background Technology

[0002] Invisible screens are favored by consumers for their aesthetic appeal and ease of use, and are widely used in construction companies and homes. These screens feature automatically retractable mesh, primarily for ventilation and mosquito prevention. The frame is tightly attached to the window frame; when needed, the mesh is pulled down, and when not in use, it automatically retracts into the screen box. When the window is open, the screen effectively blocks insects and debris; when closed, it rolls up, preventing dust and damage while maintaining window transparency. It also saves space, provides strong sealing, and complements high-end home décor.

[0003] However, existing invisible screen windows suffer from design flaws in their rolling structure. The return spring is directly connected to the fixed shaft, resulting in high axial resistance of the spring. In addition, the wind-resistant structure design within the track is not entirely reasonable, causing the screen to run with high resistance and not be flexible, leading to incomplete retraction. Furthermore, single tension springs are prone to damage after prolonged use and easily lose elasticity after rusting and aging, affecting the use of the screen window.

[0004] Existing retractable screen window roll-up structures still have some problems. In order to maintain structural strength, the roll-up rods are often designed to be quite thick and heavy, and their size is relatively large. As a result, the screen box for storing various parts is often quite large, which affects the overall aesthetics of the retractable screen window and the window's lighting effect. Currently, traditional roll-up rods mostly use round hollow profiles. When the screen window is large and the amount of screen rolled up is large, the length and weight of the roll-up rod often cause bending and deformation, excessive deflection, unstable operation, and shaking. This leads to an imbalance of force on both sides when the screen is rolled back, resulting in unstable operation on both sides and problems such as fraying.

[0005] When existing invisible screen windows and doors are used in the southern coastal areas, they may be damaged by strong winds during typhoons and other weather conditions. This is because the windproof sheet is usually a simple single plastic sheet, which is not firmly connected to the profile and sliding track. During repeated use, especially when the wind reaches a certain intensity, the windproof ability is greatly reduced. The structural strength of the windproof sheet is insufficient, and it is easy to deform, causing the windproof sheet and screen to derail, thus affecting the function.

[0006] Currently, most screen windows are assembled using corner brackets and corner pieces, which means they are fixed together by corner brackets. To fix them, it is often necessary to nail or screw the corner brackets and profiles, or to pre-drill holes and threads. The processing is complicated, and it is inconvenient to disassemble and replace them. During disassembly and assembly, the profiles and parts are easily damaged, affecting the use of the screen window. In addition, this connection method also affects the aesthetics and the overall effect of the screen window.

[0007] Currently, the connection method for the pull beam and mesh clips of invisible screen windows mostly uses fixed mesh clips or plastic sheets for sewing. The process is complicated and cumbersome, requiring more tools and equipment, making it inconvenient for assembly and production. In addition, it often requires nailing for fixation, which is troublesome during replacement and can easily damage the profile or parts. Furthermore, the connection method using plastic sheets is often disposable and cannot be reused, resulting in waste when replacing them. Moreover, ordinary mesh clips or plastic sheets often have a relatively simple structure, making them prone to deformation and damage, which can cause them to detach from the pull beam profile and damage the screen window.

[0008] To address the above issues, a novel windproof roller shutter for concealing window screens is proposed. Summary of the Invention

[0011] Furthermore, the bottom of the yarn box end cover has a self-locking buckle and is connected to the profile through the self-locking buckle. The disc spring has fixed bends on both the inside and outside. The top of the disc spring groove has an opening. The disc spring fits tightly into the opening of the disc spring groove through the fixed bend on the outside. The coupling has a bearing groove on the side near the disc spring groove. The bearing is installed and pressed tightly into the disc spring groove. The coupling has a disc spring fixing ring on the side near the disc spring groove. The disc spring fixing ring has a slot. The internal bend of the disc spring is fixed to the disc spring fixing ring through the slot and is fixed by pressing it into the disc spring groove through the coupling. One end of the coupling is round and the other end is gear-shaped. The middle part of the coupling is disc-shaped. The diameter of the disc-shaped part of the coupling is the same as the diameter of the disc spring groove. The damper is a combination of a one-way damper and a two-way damper. One end of the damper is connected to the connecting shaft in the middle of the disc spring groove in the yarn box end cover. The other end of the damper is gear-shaped.

[0012] Furthermore, the yarn pressing structure includes a yarn winding rod, a yarn pressing groove, a pressure cap, toothed protrusions, and toothed reinforcing beams. The yarn winding rod has a yarn pressing groove on its surface, and the cross-sectional shape of the yarn pressing groove is a groove with protrusions on both sides. A pressure cap is provided above the yarn pressing groove, and the pressure cap is π-shaped. The pressure cap and the yarn pressing groove are connected by two protrusions at the lower end of the π-shape and the groove with protrusions on both sides. The yarn winding rod is a hollow long strip, and there are toothed protrusions inside the yarn winding rod. The yarn winding rod is connected to the gear-shaped end of the damper through the toothed protrusions. The yarn winding rod is also connected to the gear-shaped end of the coupling through the toothed protrusions. Multiple toothed reinforcing beams are evenly distributed on the outer ring of the yarn winding rod.

[0013] Furthermore, the windproof structure includes a double-limiting windproof plate and a guide rail. The guide rail is connected to the profile, and the double-limiting windproof plate is provided inside the guide rail. The double-limiting windproof plate is connected to the mesh by a stitch. The double-limiting windproof plate includes a limiting part, a sliding part, a yarn-pressing positioning part, and a yarn-pressing part. The end of the limiting part is fixedly connected to the sliding part, the sliding part is fixedly connected to the yarn-pressing positioning part, the yarn-pressing positioning part is fixedly connected to the yarn-pressing part, and the limiting part extends into the guide rail.

[0014] Furthermore, the limiting part is fork-shaped, the middle part of the limiting part is connected to the sliding part, the yarn pressing positioning part is protruding, the sliding part is connected to the middle part of the yarn pressing positioning part, and the lower part of the other end of the yarn pressing positioning part is connected to the yarn pressing part.

[0015] Furthermore, the self-locking structure consists of a connecting angle bracket and a self-locking buckle. There are two self-locking buckles, which are fixedly connected to the connecting angle bracket at a 90-degree angle. Each self-locking buckle includes a slot, a tower spring, and a locking button. The slot is inserted into the profile, and the tower spring is installed in the slot. The surface of the slot has an opening, and the locking button is installed in the opening of the slot. The locking button is connected to the tower spring. The profile has an opening, and the locking button extends out from the opening of the profile.

[0016] Furthermore, the yarn clamping structure includes a pressure strip and a yarn clamping strip. The pressure strip is an O-shaped long strip structure with fine teeth on its surface. The yarn clamping strip is C-shaped. The pressure strip and the yarn mesh are pressed into the yarn clamping strip by rollers. The opening diameter of the C-shape of the yarn clamping strip is smaller than the combined thickness of the pressure strip and the yarn mesh. The C-shaped yarn clamping strip is disposed in the tie beam profile and is kept stable in the groove of the tie beam profile by a three-point fixing method.

[0017] The beneficial effects of this invention are:

[0018] This invention replaces the traditional return spring with a coil spring structure, using two coil springs instead of one tension spring. This ensures even force distribution on both sides of the yarn winding shaft, improving the durability and reliability of the equipment. Furthermore, the coil springs eliminate the need for an excessively long fixed shaft for connection and placement; instead, they are integrated into the end cap of the yarn box, resulting in a more compact structure that can accommodate various sizes of screens, offering strong adaptability. By incorporating double-sided dampers, the force balance on both sides of the screen is controlled. Especially during screen rewinding, there is no need to worry about uneven force distribution causing fraying due to differences in speed, force, or angle. The dampers provide damping during both the pulling down and rebounding of the screen, making the opening smoother and allowing for arbitrary stopping upon release. Rewinding is also more uniform, providing better cushioning and preventing fraying or damage caused by excessive speed. The double-sided coil spring structure effectively avoids operational issues caused by the aging of a single return spring. High resistance can prevent screens from moving freely, causing them to jam or fail to retract properly. By using coil springs instead of traditional return springs, the assembly length of the screen and the requirements for profiles and parts can be greatly reduced. A compact coil spring occupies less than one centimeter of space, achieving the size and effect of a return spring that requires nearly half a meter of space. Furthermore, the double coil springs act as a double safety measure, effectively reducing spring aging, rust, breakage, and loss of elasticity, thus improving the reliability and durability of the retractable screen. The double-sided coil spring structure avoids the large number of profiles, parts, fasteners, bearings, and other components required for assembly and fixing traditional retractable screens, greatly simplifying the assembly process and reducing labor time. The identical structure on both sides is easy to operate, and the parts are standardized, significantly reducing production and labor costs while improving the performance and durability of the screen.

[0019] By adopting a unique π-shaped yarn pressing structure, the pressing cap and the pressing groove are separate structures. During assembly, the mesh is placed flat on the pressing groove, and the pressing cap and mesh are pressed directly into the pressing groove using tools such as a hammer, thus achieving a quick installation effect. At the same time, the pressing cap can quickly flatten the mesh without wrinkles, thereby realizing rapid yarn pressing. This design does not require a large amount of equipment, parts, tools, adhesives, etc., and can basically complete the installation with just a hammer. While achieving rapid yarn pressing, it ensures the flatness of the mesh and the firmness of the connection.

[0020] By improving the yarn winding rod, the aforementioned pressure cap and yarn pressing groove are combined into a yarn winding rod, and the structure is strengthened, thus greatly increasing the structural strength of the yarn winding rod and avoiding the occurrence of yarn winding rod breakage, aging and deformation. At the same time, it increases reliability and stability, avoids the problem of excessive deflection when winding yarn, and thus ensures the balance and uniform force on both sides when the screen window is rolled back, avoiding phenomena such as jamming and mesh fraying.

[0021] By improving the yarn winding rod, several toothed reinforcing beams are added to the structure of the yarn winding rod, which can effectively play a role in anti-slip and stability, increase the contact area of ​​the yarn winding rod, increase the amount of yarn wound, increase the strength of the yarn winding rod, reduce the deflection during rotation, and improve the stability during yarn winding.

[0022] By improving the structure of the yarn roller, the strength of the yarn roller can be increased while the diameter and size of the yarn roller can be greatly reduced. It can be made one-third or even half the diameter of ordinary yarn rollers currently on the market. This greatly reduces the size of the screen box and profiles to be installed, realizing the invisible screen design of ultra-thin screen windows and ultra-narrow edge screen windows. This enhances the overall aesthetics of the screen window, reduces light blockage, and greatly improves the lighting effect of the screen window.

[0023] In the assembly of the screen, windproof strips, and sliding rails, the limiting part of the windproof strip is inserted into the sliding rail, the sliding rail is installed in the profile, the sliding part of the windproof strip is placed on the sliding rail, the screen is placed on the pressing part of the windproof strip and abuts against the upper half of the pressing and positioning part of the windproof strip, the screen and the pressing part are sewn together by a sewing machine, windproof strips are installed on both sides of the screen, the limiting part of the windproof strip is installed into the sliding rail, and then fixed to the profile to complete the installation. This can prevent the windproof strips and screen from coming out of the sliding rail when the wind is too strong, which would cause damage to the screen window.

[0024] Among them, the limiting part adopts a fork-type opening structure, which reduces weight while increasing strength. It can be effectively locked into the slide rail to prevent the windproof sheet from coming out of the slide rail. Especially when dealing with typhoons that are prone to occur in the south, it can effectively prevent the windproof sheet and mesh from coming out of the slide rail due to the excessive wind force of the typhoon.

[0025] The fork-shaped opening structure of the limiting part improves the balance and stability of the double limiting windproof sheet, while also increasing strength. It also facilitates yarn winding, reduces the tension of the coil spring during yarn winding, thereby increasing the service life of the screen and improving its performance.

[0026] Sliding part: The length of the sliding part provides a certain adjustment space, which can meet the needs of different adjustment space when the screen window is pushed and pulled, so as to meet the adjustment needs of screen windows of different sizes;

[0027] Yarn pressing and positioning part: The added protruding structure makes it easier to operate when pressing yarn, provides a better positioning point, facilitates the positioning and installation of the yarn mesh, and prevents the yarn mesh from being crooked or not straight during sewing;

[0028] The total length of the three parts—limiting part, sliding part, and yarn pressing and positioning part—is 6mm. The limiting part and the yarn pressing and positioning part are at the same height, both higher than the sliding part connected in the middle, thus forming a double convex point structure, which makes the yarn winding more balanced, the force more even, and the yarn winding smoother.

[0029] The space between the sliding part and the pressing and positioning part ensures that when the mesh is sewn onto the pressing part, there is a certain distance between it and the screen profile and the slide rail. This effectively prevents the mesh from contacting and rubbing against the slide rail during use, thus preventing the mesh from fraying. In other words, the mesh is separated by the pressing and positioning part, completely avoiding friction and damage between it and the profile and the slide rail.

[0030] The yarn pressing and positioning part adopts an asymmetrical design, that is, one side is thick and the other side is thin. When in use, the yarn can be fixed on the thick side, which can prevent some thicker yarn from being higher than the protrusions of the yarn pressing and positioning part, thus preventing friction with the slide rail or profile and causing fraying. In addition, this design can also make the yarn closer to the center, the force is more balanced when rolling the yarn, and the screen window is smoother when pulling down and rolling back.

[0031] The double-limiting structure windproof sheet has been improved and enhanced in terms of structural strength, stability and connectivity compared with the ordinary single-piece plastic windproof sheet. Through the integrated reinforced structure, it effectively prevents the windproof sheet from deforming and falling off due to strong winds, thus improving the service life of the screen window.

[0032] The button-type or snap-locking structure enables a completely nail-free assembly, eliminating the need for pre-drilling holes in corner brackets and profiles, pre-threading, and corner cutting and assembly required by existing assembly methods. This simplifies the processing flow and improves production efficiency. Furthermore, the button-type or snap-locking connection and disassembly allows for one-click assembly or separation, facilitating screen maintenance and mesh replacement. This avoids the damage, deformation, and other issues associated with repeated disassembly and reassembly caused by traditional nail and screw assembly methods. Additionally, the locking points are located at the rear of the screen, invisible from the front, preventing the unsightly impact of traditional drilling methods. The overall structure of the connecting components is more compact, the processing is simpler, operation is more convenient, and the overall effect is more aesthetically pleasing.

[0033] The C-shaped mesh clip features a unique C-shaped structure. Its key feature is that even with slight displacement and deflection during the pulling of the pull beam and mesh, the C-shaped clip remains fixed at three points within the pull beam groove. This three-point positioning method prevents significant rotation or detachment, ensuring the usability and reliability of the screen. Simultaneously, the C-shaped clip and mesh allow for some movement within the pull beam groove, accommodating adjustments and flattening of the mesh. During installation and use, the C-shaped clip requires no sewing or nailing, allowing for natural adjustment. While preventing detachment, it maintains even tension on the mesh based on the applied force. When taut, the clip moves upwards, secured at three points to prevent detachment; when relaxed, it moves downwards to the bottom of the profile groove for easier flattening and reduced tension on the mesh. The C-shaped mesh clip is also more practical, allowing for… With the matching O-ring, various rubber strips or sponge strips can also be used, making it more versatile. Furthermore, the C-shaped yarn clamping strip adopts an integrated structure; the yarn mesh and O-ring are directly pressed into the C-shaped clamping strip using rollers to complete the yarn mesh installation, eliminating the need for sewing, nailing, screwing, or other processes and equipment. Simultaneously, since no sewing or nailing is required, replacing the yarn mesh is much easier. Simply remove the C-shaped clamping strip, yarn mesh, and clamping strip directly from the side of the pull beam groove, and then remove the clamping strip from the side of the C-shaped clamping strip to complete disassembly—all without tools or machinery. Because the C-shaped clamping strip uses rollers to directly press in the yarn mesh, eliminating the need for nailing or sewing, the clamping strip is minimally damaged during repeated use and yarn mesh replacement. The O-ring used can be reused multiple times without affecting the yarn pressing and clamping effect, thus significantly reducing the cost of replacing the yarn mesh and facilitating maintenance and use.

[0052] Furthermore, the windproof structure includes a double-limiting windproof plate and a guide rail. The guide rail is connected to the profile, and the double-limiting windproof plate is provided inside the guide rail. The double-limiting windproof plate is connected to the mesh by a stitch.

[0056] Example 2

[0057] Place the yarn mesh flat on the yarn pressing groove of the yarn winding rod. Place the pressure cap on top of the yarn mesh and the pressing groove, and use a hammer or other tools to tap it to press the pressure cap and yarn mesh together into the pressing groove, completing the fixing and fabrication of the yarn winding rod. Place the coil spring into the coil spring groove, and fit it tightly with the opening of the coil spring groove through the fixing bend on the outside of the coil spring. Insert the folded edge of the inner opening of the coil spring into the slot in the coil spring fixing ring of the coupling for fixing. Install the bearing into the bearing groove in the center of the coupling. Insert the coupling through the central bearing into the connecting shaft in the center of the coil spring groove on the end cover of the yarn box, and fit it tightly with the coil spring groove. Press the coil spring and bearing together. Then insert one end of the damper's drum-shaped opening into... Connect the damper gear-shaped end to the yarn winding rod in the connecting shaft at the center of the disc spring groove on the yarn box end cover. Insert the damper into both sides of the yarn winding rod. Use the toothed convex strip inside the yarn winding rod to fix the gear on the outer ring of the damper, making them mesh together. Connect the yarn winding rod to the coupling. Use the toothed convex strip inside the yarn winding rod to fix the toothed end of the coupling, making them mesh together. The rotation of the yarn winding rod drives the coupling and the outer ring of the bearing to rotate, which in turn drives the disc spring to rotate and store force. Connect the yarn box end covers at both ends to the profiles on both sides through self-locking buckles. Press the locking button and then insert the square self-locking buckle into the profile. When the locking button reaches the opening on the profile, the tower in the empty groove... The spring extends, pushing the locking button out of the profile to complete the self-locking process. The mesh and O-shaped pressure strip are pressed directly into the C-shaped clamping strip using a roller to secure them together. Then, the entire assembly is inserted from the side into the groove of the bottom tie beam profile, completing the fixing and fabrication of the tie beam section. The two sides of the mesh are sewn together with the pressure sections of the windproof panels on both sides using a sewing machine. The limiting part of the windproof panel is inserted into the guide rail, the sliding part of the windproof panel is placed on the guide rail, the mesh is placed on the pressure section of the windproof panel and abuts against the upper half of the pressure positioning part, and the limiting part of the other side of the windproof panel is installed into the guide rail. The guide rail is then fixed to the profiles on both sides, completing the fabrication of the windproof panel section. When connecting the profiles on both sides and the bottom profile, insert the two self-locking buckles with a 90-degree angle fixed on the connecting brackets into the profiles respectively. The structure is the same as the connection method between the screen box end cap and the profile. At this time, the screen assembly is completed. Since the damper uses a combination of unidirectional damper and bidirectional damper, when the screen is pulled down, the unidirectional damper takes effect, and the forces of the dampers on both sides cancel each other out, allowing the screen to stay at any position. If the screen needs to be retracted, just push it upwards lightly. Under the synergistic action of the dampers, the screen will automatically roll back upwards. At this time, due to the action of the dampers on both sides, the operation on both sides is more stable until the screen is completely rolled back.

[0058] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. The various components mentioned in this invention are common technologies in the existing field. Those skilled in the art should understand that the present invention is not limited to the above embodiments.
