Racing Pigeon Foot Ring Pivot Structure Without Metal Pins

The patent integrates the pivot structure directly into the movable member by forming a protruding pivot through injection molding. This merges the previously separate metal pivot component with the movable member itself, eliminating the need for additional metal parts while maintaining the pivoting connection strength between the body and movable member.

The patent changes the material parameter from metal to plastic (via injection molding) and the structural parameter from separate component to integrated feature. This parameter change reduces weight while maintaining functional equivalence of the pivoting connection through proper structural design of the protruding pivot.

The patent combines the pivot function with the movable member through injection molding, eliminating the need for separate metal pivot procurement and assembly. This integration reduces manufacturing steps and costs while maintaining connection reliability through the designed protruding pivot structure that provides stable pivoting.

The movable member is designed to include its own pivot structure (protruding pivot) that performs the connection function. This self-service approach eliminates dependency on external metal pivot components, reducing both manufacturing complexity and cost while ensuring reliable connection through the integrated design.

The patent merges the pivot component with the movable member into a single integrated part through injection molding. This reduces the total component count from four separate pieces to fewer components, simplifying assembly while preserving the detachable and adjustable nature of the foot ring for different pigeon sizes.

The movable member includes its own integrated pivot structure that enables self-assembly with the body without requiring separate metal pivot installation. This self-contained design reduces assembly complexity while maintaining the flexibility to adjust and detach for different application requirements.
