Awning Tiltable Support Device Locking Mechanism

Instead of using complex locking mechanisms to prevent upward rotation, the patent inverts the approach by using elastic extension means that naturally resist both upward and downward movements. The elastic elements are pre-tensioned to provide continuous stabilizing force, eliminating the need for mechanical locks and tiltable support devices while maintaining reliability against wind-induced oscillations.

The patent replaces expensive, complex mechanical locking mechanisms and tiltable support devices with simple, inexpensive elastic extension means. These elastic elements provide sufficient stabilization at low cost, trading off the durability of complex mechanisms for the simplicity and cost-effectiveness of elastic components.

The patent replaces rigid, fixed connection pins with dynamic elastic extension means that allow for adjustable vertical tilt. The elastic elements can be tensioned or relaxed to achieve different angular positions of the articulated arms, providing adaptability while maintaining structural simplicity. This dynamic approach allows the system to adapt to different installation requirements without complex adjustment mechanisms.

The patent enables adjustment of the vertical tilt parameter by modifying the tension or length of the elastic extension means. By changing the physical state (tension, extension) of these elastic elements, the system can achieve different angular positions and adapt to various installation scenarios while keeping the overall structure simple and avoiding complex mechanical adjustment devices.

Instead of spacing the rolling-shutter box from the wall to enable rotation, the patent inverts the approach by allowing the box to be positioned close to or against the wall. The rotational adjustment capability is achieved not by spacing but by using the elastic extension means that can accommodate angular changes without requiring clearance, thereby eliminating rain exposure through the interspace while maintaining adaptability.

The patent introduces elastic extension means as an intermediary between the rolling-shutter box and the articulated arms. This intermediary element allows for rotational adjustment and angular adaptation without requiring the box to be spaced from the wall, thus preventing rain from passing through the interspace while still enabling the necessary movement and positioning flexibility.
