Screen Shaft Mounting Bracket With Tooth-Slot Locking

The patent inverts the traditional attachment mechanism by replacing the hook-into-hole configuration with a slot-receiving-tooth configuration. Instead of the shaft holder having hooks that insert into mounting bracket holes, the mounting bracket has locking teeth that engage with slots in the shaft holder. This inversion simplifies the attachment process, eliminates the need for resilient elements, and makes attachment feasible in deep recesses where the inverted geometry allows easier access and engagement.

The patent segments the attachment interface into distinct functional elements: locking teeth on the mounting bracket, slots on the shaft holder, guide teeth for alignment, and a controllable hook mechanism. This segmentation allows each element to perform its specific function efficiently - the locking teeth provide retention, the slots enable engagement, the guide teeth ensure proper alignment, and the controllable hook allows easy attachment and detachment without requiring resilient elements.

The patent extracts and eliminates the resilient element from the attachment mechanism. Instead of using springs or elastic components to provide retention force, the design relies on the geometric engagement between locking teeth and slots. The locking teeth engage with the slots to provide reliable retention without requiring any resilient elements, thereby simplifying the device structure while maintaining or improving retention reliability.

The attachment mechanism is designed to be self-retaining through the geometric interlocking of locking teeth and slots. The configuration of these elements creates inherent retention without requiring additional components like resilient elements. The system serves itself by using the structural geometry to provide both attachment and retention functions, eliminating the need for separate retention mechanisms.
