Traditional devices that use flexible “spreader bands” (like those found in roller blinds or gates) lack stiffness, are difficult to manufacture, and don’t scale well. They struggle with linear pushing and pulling movements, often require bulky casings, and can’t easily form reliable, rigid structures.
Core Features
This invention introduces a device made of spreader bands, structural elements, and gripping/encompassing elements. The spreader bands can shift between two shapes:
- A flat, rectangular shape when stored or coiled.
- A curved, stiffened shape when deployed, where they lock onto structural elements using the encompassing grips.
A transfer device (with guides and gears) makes it simple to move between these states.
Inventive Step
The novel insight is using the natural “pincer-like” spreading motion of the bands’ edges as they curve. This motion allows the bands to automatically grip and lock around structural elements, creating a rigid, rod-like structure without needing extra casings or heavy supports. This mechanism can also integrate gears or teeth, making it driveable and more versatile than prior designs.
Tangible Benefits
- Strong yet compact: Folds away flat, stiffens when needed.
- Versatile: Works for roller blinds, garage doors, awnings, or even industrial rods.
- Simple to manufacture: Elements can be glued, snapped, or molded in place.
- Scalable: Can be built with single or multiple bands for strength.
Broader Impact
By creating lightweight, scalable rigid structures from rollable components, this invention opens doors for smarter home systems, more efficient industrial machinery, and space-saving transport solutions. Its adaptability also suggests potential in sustainable design—reducing material waste while enabling products that are stronger, lighter, and easier to install.
