Quick Coupler Rotary Wedge Mechanism Minimizes Separation Distance

The patent extracts and eliminates unnecessary intermediate components from the coupling mechanism. By using a direct pin reception channel that extends from the open mouth to the closed position, the design removes redundant structural elements that previously increased separation distance, thereby minimizing the gap between work arm and work tool for optimal leverage.

Instead of having the pin travel through a complex multi-stage path, the patent inverts the approach by designing the channel to directly guide the pin from the open mouth to the final closed position in a single continuous path. This reversal of the traditional multi-step engagement process minimizes separation distance and maximizes mechanical efficiency.

The patent merges multiple functions into a single integrated channel structure. The channel simultaneously provides pin guidance, retention, and locking functions that in traditional designs would require separate components. This consolidation reduces the number of parts, simplifies the device, and eliminates wear interfaces between multiple moving components.

The channel structure is designed to perform multiple functions: it guides the pin during engagement, retains the pin in the closed position, and provides the locking mechanism. This multi-functional design eliminates the need for separate guiding elements, retainers, and locks, thereby reducing component count and improving reliability by minimizing wear-prone interfaces.
