Description

Technical Field

[0001] This utility model relates to the field of pleated blind technology, specifically a pleated blind with an arc track. Background Technology

[0002] In RV living scenarios, curtains are an indispensable functional component. They not only play a vital role in protecting privacy and regulating light inside the vehicle, but also directly affect the overall aesthetics and living experience. However, most RV curtain products currently on the market have numerous shortcomings in design and function.

[0003] First, existing products fall short in terms of light-blocking performance and overall aesthetics. Traditional curtains typically have their fabric ends exposed, preventing a tight fit with the window frame and allowing light to seep in through the gaps, severely impacting their light-blocking effect. Furthermore, their installation often results in poor integration with the car's interior, creating an unsightly appearance.

[0004] Secondly, the problem of limited functionality is prominent. Most existing RV curtains use only one type of uniform fabric, making it difficult to meet the diverse needs of users. For example, users cannot flexibly switch between using the same window when they need to block out light and rest and when they want to maintain ventilation and light, greatly limiting their practicality.

[0005] Furthermore, user experience details are poorly considered. The pulling force of existing curtains is usually fixed, making it impossible to adjust according to individual user habits and feel, resulting in a poor user experience. In addition, the adjustment cords (or pull cords) of curtains are mostly exposed, affecting the overall visual appeal and aesthetics of the product. Moreover, the mechanical components (such as springs) are easily damaged by dust, foreign objects, or accidental contact, shortening the product's lifespan. No solutions have yet been proposed to address these technical issues. Utility Model Content

[0006] To address the problems in related technologies, this utility model proposes a curved track 2-in-100 fold curtain to overcome the aforementioned technical problems in existing technologies. The purpose of this utility model is to fundamentally eliminate the problem of incomplete light blocking caused by side light leakage in traditional curtains, meet different usage needs, allow users to adjust the tightness of the pull cord according to their needs, improve comfort, reduce malfunctions caused by dust intrusion, extend service life, enhance sealing and stability, and ensure smooth and fluid operation of the handle during pushing and pulling.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a curved track 2-in-100 fold curtain, comprising beams, two beams symmetrically distributed, connected by side rails, an outer cover on each beam, a handle on one side of each beam, a PVC sheet, fabric, and a U-shaped rail sequentially arranged between the handle and the beam, the upper and lower ends of the fabric connected to the PVC sheet and the U-shaped rail respectively, the end of the U-shaped rail away from the fabric connected to the handle, the PVC sheet on and connected to the beam, the PVC sheet having several plastic eyelets, each eyelet having a fabric loop, a pull cord inside the side rail, the two ends of the pull cord extending into the interior of each of the two beams, each end of the pull cord having a spring and a cord lock, both the spring and the cord lock being located inside the beam.

[0008] Preferably, magnetic strips are provided on the opposite sides of both handles.

[0009] Preferably, beam end caps are provided on both the left and right sides of the beam.

[0010] Preferably, both ends of the handle are provided with handle caps, which are disposed on the side rail and movably connected to the side rail.

[0011] Preferably, the beam is made of metal and its outer surface is coated with an anti-corrosion layer.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This utility model is a curved track two-in-one 100-fold curtain. By setting two beams connected by side rails, the fabric of the curtain is tucked into the side rails on both sides, which fundamentally eliminates the problem of incomplete light blocking caused by side light leakage in traditional curtains. At the same time, the stable frame formed by the beams and side rails can be perfectly embedded into the window structure of the RV. With the shielding effect of the outer cover and the beam end caps, the product can be integrated with the interior environment of the vehicle, with a clean, neat appearance and good overall integrity. This utility model is a curved track 2-in-100 fold curtain. By setting handles, U-shaped tracks, fabric and PVC sheets, it allows users to select different fabrics for the upper and lower parts to meet different usage needs. By setting rope locks and springs, users can adjust the tension of the pull rope according to their personal habits, thereby obtaining the most comfortable operating force and rebound feel. All precision parts are hidden and protected, which greatly reduces the failure caused by dust intrusion, external impact or daily wear and tear, and significantly extends the service life of the product. This utility model is a curved track 2-in-100 pleated blind. The magnetic strips on opposite sides of the two handles ensure that the blind can be tightly attracted when closed, enhancing the sealing and stability and effectively preventing shaking during vehicle movement. The movable connection between the handle end cap and the side rail ensures that the handle can be smoothly and without jamming during pushing and pulling. The plastic eyelets and fabric rings on the PVC sheet form a durable suspension system, ensuring that the pleated blind can be folded and unfolded neatly and orderly. Attached Figure Description

[0016] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Example

[0017] Please see Figure 1-4This utility model proposes a technical solution for a curved track 100-fold curtain: a curved track 100-fold curtain includes two beams 1, which are symmetrically distributed and connected by side rails 2. Specifically, the two beams 1 and the side rails 2 form a stable overall frame that can be embedded in the interior structure of a motorhome window, blending seamlessly with the interior environment for a clean appearance. An outer cover 3 is provided on the beams 1. Specifically, the beams 1 and the outer cover 3 are detachably connected, and the side rails 2 are curved. The outer cover 3 can conceal the internal structure of the beams 1, ensuring a complete product appearance. Each of the two beams 1 has a handle 4 on one side. Between the handles 4 and the beams 1, a PVC sheet 5, fabric 6, and a U-shaped rail 7 are sequentially arranged. The upper and lower ends of the fabric 6 are connected to the PVC sheet 5 and the U-shaped rail 7, respectively. The end of the U-shaped rail 7 furthest from the fabric 6 is connected to the handle 4. Next, PVC sheet 5 is set on beam 1 and connected to beam 1. Several plastic eyelets 8 are set on PVC sheet 5, and fabric rings 9 are set on plastic eyelets 8. Pull cord 10 is set inside the side rail 2. The two ends of pull cord 10 extend into the interior of the two beams 1 respectively. Both ends of pull cord 10 are set with springs 11 and rope locks 12. Springs 11 and rope locks 12 are set inside the beams 1. Specifically, pull cord 10, springs 11 and rope locks 12 are hidden inside the beams 1 and side rail 2 to enhance aesthetics. The two ends of fabric 6 can be stored in the slide of side rail 2, effectively blocking the channel for light to enter from the gaps on both sides of the curtain, thus achieving a side shading effect. The two fabrics can be set with different materials to meet different usage needs. By setting springs 11 and rope locks 12, the rebound force and damping feel when pulling and closing the curtain can be flexibly adjusted, making the operation more comfortable and smooth.

[0018] Please see Figure 1-4 As shown, magnetic strips 13 are further provided on opposite sides of the two handles 4.

[0019] In this embodiment, the magnetic strip 13 enables the two half-length curtains to be tightly attracted by magnetic force when closed, which enhances the stability and privacy of the closure and further improves the user experience.

[0020] Please see Figure 1-2 As shown, beam caps 14 are further provided on both the left and right sides of the beam body 1.

[0021] In this embodiment, the beam end cap 14 can prevent external impurities from entering the interior of the beam 1, reduce failures caused by dust intrusion, external impact or daily wear, and significantly extend the service life of the product.

[0022] Please see Figure 1-2 As shown, furthermore, handle end caps 15 are provided at both ends of the handle 4. The handle end caps 15 are provided on the side rail 2 and are movably connected to the side rail 2.

[0023] In this embodiment, the handle end cap 15 can seal both ends of the handle.

[0024] Furthermore, beam 1 is made of metal, and the outer surface of beam 1 is coated with an anti-corrosion layer.

[0025] In this embodiment, the beam 1 is made of aluminum alloy or stainless steel to extend its service life, and the anti-corrosion layer can effectively prevent corrosion.

[0026] The working principle of this utility model: Opening and closing process: The user directly holds and pushes and pulls the handle 4. The handle 4 drives the entire fabric 6 and PVC sheet 5 to move together through the U-shaped rail 7. The two sides of the fabric 6 are constrained in the slide of the side rail 2 to ensure that it moves smoothly and steadily without deviation and can be neatly folded or unfolded. When the two handles 4 are pushed to the middle closed position, the magnetic strips 13 on their inner sides attract each other to ensure the tightness and stability of the curtain closure and effectively prevent shaking and gaps caused by vibration during vehicle movement.

[0027] The process of adjusting the operating force: This function is achieved through the pull cord 10, spring 11 and cord lock 12 hidden inside the beam 1. Users can adjust the effective length and tension of the pull cord 10 by operating the cord lock 12, thereby changing the rebound force applied by the spring 11. Users can customize the pulling force and rebound speed required when opening and closing the curtains according to their personal feel, and obtain the most comfortable operating experience.

[0028] Function switching and light-blocking process: The upper and lower parts of the curtain (controlled by two independent handle units 4) can be made of different fabrics 6 (such as blackout fabric for the upper part and light-transmitting mesh for the lower part). Users can operate the upper or lower handles 4 separately to achieve various scene modes such as blackout for the upper part and light transmission for the lower part, which greatly improves practicality. When the curtain is fully closed, the fabric 6 is embedded in the side rail 2, the top is sealed by the beam 1 and the outer cover 3, and the middle is attracted by the magnetic strip 13, forming an all-round blackout system from the edge to the center, which fundamentally eliminates light leakage.

[0029] The entire system is supported by a rigid frame consisting of beam 1 and side rail 2, with all moving parts operating under the guidance and protection of the rails and enclosure. The handle end cap 15 ensures the smooth movement of the handle 4 on the side rail 2, while the beam end cap 14 prevents dust from entering the internal mechanism. This design not only ensures the reliable operation of each functional module but also gives the product a high degree of overall aesthetics and durability.
