Abstract
Description
Technical Field
[0001] The utility model relates to the field of rolling blinds, in particular to a blind fabric and a rolling blind comprising the same. Background Art
[0002] In daily life, curtains are used extensively. For example, in windproof roller blinds, the windproof function of the curtains is achieved by the limiting mechanisms on both sides of the curtains and the limiting openings on the side rails. Most of the limiting mechanisms are made of plastic or metal, and are manually or machine rolled when installed on the curtains. In order to ensure the reliability of the installation of the limiting mechanisms, the edges of the limiting mechanisms are usually interference fit with the curtains. Although this interference fit can ensure the reliability of the curtains during operation, it also causes wrinkles in the curtains at the limiting mechanisms during operation, which seriously affects the smoothness and reliability of the curtains during use.
[0003] Ordinary rolling shutters are composed of a power source on the top, a reel, a curtain, a counterweight rail and a side rail. When the curtain needs to rise, the power source rotates and drives the reel to rotate along its own axis, and the curtain begins to wrap around the reel, thereby achieving the purpose of raising the curtain. When the curtain needs to lower, the power source rotates in the opposite direction, and the curtain is released on the reel, and moves downward under the influence of the gravity of the curtain itself and the counterweight rail at the bottom, thereby achieving the purpose of lowering the curtain.
[0004] Ordinary windproof roller shutters work together with guide rods, zippers or bead buckles and side rails. Specifically, the side rails on both sides of the curtain are installed with guide rods, zippers or bead buckles. When the curtain is in the lowered state, the curtain will drive the guide rods, zippers or bead buckles to move together. Since the diameter or thickness of the guide rod, zipper or bead buckle is larger than the side rail opening, it will interfere with the side rail, so that the curtain will not fall off the side rail.
[0005] However, due to problems with the side rail assembly of the curtain or deformation over time, the guide rod, zipper or bead buckle often shifts during the operation of the curtain. In severe cases, the guide rod, zipper or bead buckle will slide out of the side rail, making the curtain unable to work normally. When the guide rod, zipper or bead buckle slides out of the side rail, the roller blind will completely stop working. Utility Model Content

[0029] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present utility model will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.
[0030] This embodiment provides a curtain fabric, Figure 1 is a first schematic diagram of a curtain fabric according to an embodiment of the present utility model, as shown Figure 1 As shown, at least one side of the curtain 10 is provided with a sliding component 20; at least one side of the curtain is provided with a disconnecting portion 30, and the disconnecting portion 30 is arranged between the sliding components 20; when the curtain 10 is rolled up, the disconnecting portion 30 is used to accommodate the sliding component 20.
[0031] In the related art, the windproof function of the curtain is achieved by the limiting mechanisms on both sides of the curtain and the limiting openings on the side rails. Most of the limiting mechanisms are made of plastic or metal products and are rolled manually or by machines when installed on the curtain. In order to ensure the reliability of the installation of the limiting mechanism, the edge of the limiting mechanism is often interference fit with the curtain. Although this interference fit can ensure the reliability of the curtain during operation, it also causes the curtain to wrinkle at the limiting component, which seriously affects the flatness of the curtain. Through the technical solution in the above embodiment, due to the provision of the disconnection part 30, the stress transmission between the surrounding of the limiting component 20 and the edge of the curtain 10 is blocked by the disconnection part, thereby ensuring that the edge of the curtain 10 is flat and wrinkle-free when rolled up. In addition, during the operation of the rolling curtain, the sliding component 20 on at least one side of the curtain can slide in the side rail 4, thereby greatly reducing the resistance of the curtain 10 to the movement of the side rail 4, making the extension and contraction of the curtain smoother, and at the same time, it can cope with more complex application conditions, such as sloped side rails, triangles, trapezoidal curtains, etc.
[0032] As a preferred embodiment, preferably, the sliding component 20 and the disconnecting portion 30 are spaced apart. The spacing distance can be set according to actual needs. For example: the spacing distance between the sliding component and the disconnecting portion is 1 to 100 cm; or the spacing distance between the sliding component and the disconnecting portion is 5 to 20 cm. It should be noted that the sliding component and the disconnecting portion are not necessarily arranged at the same alternating intervals, and also include unequal alternating intervals. Preferably, the sliding component 20 may include one or both of a pulley ball or a sliding ball. It should be noted that the description here is only for illustrative purposes and does not constitute a limitation of the present application. Those skilled in the art can select other components in the relevant technology to set the sliding component as needed. When setting, the minimum diameter size of the sliding component 20, for example, the thickness of the pulley ball or the diameter of the sliding ball is larger than the minimum opening size of the side rail to prevent the sliding component 20 from falling off and sliding out of the side rail 4, so as to avoid the curtain being unable to be used normally due to external force, thereby achieving the role of limiting.
[0033] As a preferred implementation method, Figure 2As shown, the disconnection portion 30 includes an opening of a preset shape. It should be noted that those skilled in the art can set the shape of the opening according to actual needs. As long as the stress transfer around the sliding component 20 can be blocked, the disconnection portion 30 can be used to accommodate the sliding component 20. For example, a U-shaped disconnection portion, a semicircular disconnection portion, a trapezoidal disconnection portion, a shear-type disconnection portion, etc. are all within the technical solution claimed for protection in the present utility model. In practice, the disconnection portion 30 can accommodate part or all of the sliding component 20, and the size of the disconnection portion 30 can be inconsistent. Adaptive adjustment can be made according to actual working conditions or a mixed setting of multiple disconnection portion shapes can be made. Preferably, the opening size of the disconnection portion 30 close to one end of the transmission shaft is smaller than the opening size of the disconnection portion away from one end of the transmission shaft. Through the opening in the preferred embodiment, it can be achieved that (1) when the curtain is rolled up, the sliding components can be arranged in a staggered manner, so that the curtain will not affect the curling shape of other layers of the curtain or cause wrinkles to form when the curtain is rolled up due to the setting of the sliding components causing the thickness of the curtain at the sliding components to be greater than the thickness of the rolled-up curtain itself; (2) when the curtain is in a released state, it is necessary to prevent the curtain from shifting relative to the side rail and causing the curtain to detach from the side rail. The sliding components at the edge of the curtain can cooperate with the side rail to limit the displacement of the curtain and slide out of the side rail to resist external interference, such as wind.
[0034] As another preferred embodiment, the curtain may also include: a reinforcement part for installing the sliding component. It should be noted that reinforcement refers to attaching another layer of material to the surface of the reinforcement part of the curtain to prevent the sliding component from interfering with the side rail during the displacement of the curtain. The curtain will not be damaged due to excessive stress of the sliding component at the installation position. The reinforcement methods include but are not limited to welding, bonding, and sewing. The reinforced materials include but are not limited to curtains, metals, plastics, ceramics, nylon, rubber, polyester, and glass fiber materials. Using the reinforcement part to install the sliding component can increase the installation reliability of the sliding component.
[0035] As another preferred embodiment, the curtain fabric may also include: irregular polygonal curtain fabric, for example, it may be one or more of any curtain fabric shapes that can meet the actual working condition requirements, such as square, rectangle, triangle, parallelogram, trapezoid, etc.
[0036] This embodiment provides a rolling blind. Figure 3 is a schematic diagram of a rolling shutter according to an embodiment of the utility model, Figure 4 is a front view of a rolling curtain according to an embodiment of the utility model, Figure 5 2 is a front view of a curtain according to an embodiment of the present utility model, as shown in FIG. Figure 3 , 4As shown in Figures 1 and 5, the rolling curtain includes: a power source 1, a transmission shaft 2, a guide mechanism 3, a side rail 4 and the curtain 10 in the above embodiment and its preferred embodiment; wherein the curtain 10 is installed on the transmission shaft 2, the power source 1 drives the transmission shaft 2 to rotate, and drives the curtain 10 to move. When the curtain 10 moves, the sliding component 20 on at least one side of the curtain 10 moves in the side rail 4, and the guide mechanism 3 is arranged on the side rail 4. The guide mechanism 3 is usually arranged in a funnel-shaped structure. When the position of the sliding component 20 is not good, such as relative displacement, bending and other special situations that are easy to occur during the use of the curtain, the funnel-shaped design of the guide mechanism can collect and correct the sliding components 20 in the aforementioned bad position, and smoothly guide them into the side rail 4; on the other hand, when the sliding component 20 slips off the side rail 4, the sliding component that has separated from the side rail can be reintroduced into the side rail 4 through the guide mechanism 3.
[0037] As a preferred implementation method, Figure 6 and Figure 7 As shown, the guide mechanism 3 includes: a guide flap 302 . Figure 6 is a schematic diagram of a guide mechanism according to an embodiment of the utility model, Figure 7 It is a schematic diagram of the side rail, guide mechanism and curtain according to an embodiment of the utility model. When the sliding component 20 is separated from the side rail and moves toward the direction close to the transmission shaft 2, it passes through the guide mechanism 3, and the guide flap is flipped up toward the transmission shaft to guide the sliding component 20 onto the transmission shaft; when the sliding component moves in the direction away from the transmission shaft, the sliding component is guided into the side rail through the guide mechanism.
[0038] Preferably, as shown in Figure 7, the guide mechanism 3 includes: an elastic component 305 connected to the guide flap 302, so that the angle between the guide flap 302 and the transmission shaft 2 is less than 90 degrees.
[0039] As a preferred implementation method, Figure 4 , Figure 7 As shown, the guide mechanism 3 may further include a rotating shaft 304 and a limiting component 303 to cooperate with the guide flap 302 to complete the guiding function of the curtain. Figure 7 As shown, when the curtain is rolled up toward the transmission shaft, due to the minimum diameter of the sliding member 20, as shown in Figure 7As shown in , the thickness of the two pulley balls, or the overall diameter of the sliding balls, etc., is larger than the opening 3A of the guide mechanism and the width 4A of the opening between the guide flaps, so the guide flap 302, driven by the curtain, will flip up around the rotation axis 304 in the direction of the transmission shaft, allowing the curtain to pass freely through the guide mechanism, especially when a sliding component 20 slides out of the side rail, the sliding component 20 can freely pass through the guide mechanism to return to the transmission shaft or to any position between the transmission shaft and the guide mechanism. When the curtain is lowered again, the guide flap, driven by the curtain, its own gravity or the action of the elastic component, will flip around the rotation axis 304 in the direction of the curtain release, and will be blocked and positioned by the limit mechanism 303. Because the minimum diameter of the sliding component 20 is larger than the opening 3A of the guide mechanism and the width 4A of the opening between the guide flaps, the sliding component 20 will enter the side rail 4 through the guide mechanism 3, realizing the automatic correction and repair of the rolling curtain.
[0040] Preferably, if Figure 7 As shown, the guide mechanism 3 may also include: an opening 3A for accommodating the passage of the curtain. At least one side of the inner wall of the guide mechanism 3 has an inclined feature for guiding the sliding component 20, wherein, preferably, the width of the opening 3A is the same as the opening size between the flaps in the flap guiding state, and of course, it can also be set to be different, but the width of the opening 4A formed between the opening 3A and the flap guiding state should be smaller than the minimum diameter of the sliding component 20. When the curtain is released, since the sliding component 20 cannot pass through the opening 3A and the opening in the middle of the flap along the direction of curtain release, and the bottom edge of the inclined surface of the guide mechanism is connected with the upper end of the through-length opening of the side rail 4, the sliding component 20 will continuously enter the side rail 4 under the guidance of the guide mechanism 3, especially when a sliding component 20 with poor positioning moves to the guide mechanism 3, the guide mechanism will correct the sliding component with poor positioning, and then guide the sliding component 20 to slide smoothly into the inside of the side rail 4, and play the role of sliding and limiting again.
[0041] This embodiment provides a rolling blind, such as Figure 3 , 4 As shown in 5, the rolling shutter includes a power source 1, a transmission shaft 2, a guide mechanism 3, a side rail 4, and a curtain 10. In the present embodiment, the power source 1 is connected to the transmission shaft 2 and drives the transmission shaft 2 to rotate. The curtain 10 is wound around the transmission shaft 2. The guide mechanism 3 is installed between the side rail 4 and the transmission shaft 2. A sliding component 20 is installed on at least one side of the curtain 10.
[0042] like Figure 7As shown, after the installation of the roller blind is completed, the sliding component 20 on at least one side of the curtain should be installed in the side rail 4. When external force acts on the curtain 10, the curtain 10 will move together with the sliding component 20 on at least one side of the curtain 10. Since the minimum diameter of the sliding component 20 is larger than the minimum opening size of the side rail 4, the sliding component 20 and the side rail 4 will interfere with each other, making it impossible for the curtain 10 to move further out of the side rail, thereby achieving the purpose of limiting and further realizing the windproof effect.
[0043] In actual use, if the sliding component 20 of the curtain 10 is separated from the side rail 4, the sliding component 20 will fail to function, affecting the normal operation of the curtain. At this time, the curtain 10 can be rolled up, and when the separated sliding component 20 moves to the guide mechanism 3, since the guide flap 302 of the guide mechanism 3 can be turned over, the sliding component 20 will pass through the guide mechanism 3 and be rewound onto the transmission shaft 2 (transmission tube). Since the curtain 10 has surface tension, the sliding component 20 can return to the initial position.
[0044] Through this preferred embodiment, the curtain of the roller blind can be ensured to be flat and wrinkle-free when it is rolled up or lowered, and when the curtain is rolled up on the rolling tube, the height of the sliding component will not affect the flatness of the curtain.
[0045] In summary, through the above embodiments and their preferred implementation modes, a curtain and a rolling blind comprising the same are provided, which solves the long-standing technical problems in the related art such as curtain wrinkles during operation of the rolling blind, assembly of the rolling blind and irreparable detachment of the sliding limit components from the side rails due to aging, by arranging sliding components on the curtain and a breaking part on the curtain, thereby improving the reusability, reliability, stability and service life of the rolling blind.
