cordless lift system

Modern and practical, cordless blinds and shades are an alternative to conventional blinds that need cables to operate. In addition to providing a neat, uncluttered appearance, they remove any possible safety risks related to loose wires. The straightforward yet efficient mechanism of cordless blinds offers precise control over light and privacy together with ease of use.   A spring-loaded or motorized system is the main working mechanism of cordless blinds. The spring mechanism in manual cordless blinds is usually found inside the bottom rail or headrail. Pulling down on the bottom rail causes the spring's tension to be released, enabling the blinds to roll up when you desire to lift them. You only need to press down on the bottom rail to the desired point to drop the blinds. At whatever height, the spring tension aids in keeping the blinds in place.   The cordless lift mechanism developed by our company are different from the wire springs on the market, we apply variable force springs.   SAFETY & CONVENIENCE: The variable force spring design allows the cordless roller shade to stop at any position, providing a better user experience and convenience.  This design eliminates the safety risks associated with traditional pull cords and is especially safe for homes with children and pets. Precise Positioning: Variable force springs ensure precise positioning of the roller shades when moving up and down, with an accuracy of 2mm or less,  which means that users can stop the roller shades in any position as needed, without slipping or bouncing. Durability: Variable force springs typically have a long service life of 10,000 operations or more, while maintaining a low level of force decay (within 5%), which means that the springs maintain their performance even after long periods of use. Cost Effective: Variable force spring systems may be less costly than traditional wire spring systems because it reduces the need for complex components such as deceleration devices, damping devices, etc., which reduces the overall cost. Ease of Maintenance: Due to their simple construction, variable force spring systems are easy to maintain and clean, reducing maintenance costs and effort. Aesthetics: Cordless roller blinds are designed to be more simple and aesthetically pleasing. The spring assembly is usually hidden inside the roller blind and does not detract from the appearance of the curtain. Suitable for a variety of environments: Variable force spring systems can be applied to a variety of sizes and types of windows, including high speed railroads and side window shades on railroad cars, providing a wide range of applications.   These advantages make variable force springs the ideal choice for cordless roller shade systems, improving product market competitiveness and user satisfaction.
