Indoor Putting Practice Box With Gravity-Fed Automatic Ball Return

The patent combines the mat structure with integrated leveling mechanisms (screw jacks or shims) and drainage systems into a single unified apparatus. This merging allows the mat to be elevated and leveled independently of the floor, resolving the contradiction between indoor adaptability and floor levelness by making the levelness feature self-contained within the mat assembly.

The patent creates a scaled-down replica of a real golf hole within the mat structure, complete with a cup that accepts actual golf balls. This copying approach maintains the essential characteristics of a real hole (ball dropping into a cup) while adapting it to indoor practice conditions, thereby preserving authenticity while enabling convenient practice targets.

The patent incorporates an automated ball return system that uses gravity-fed chutes and ramps to automatically return golf balls to the starting position after they exit the hole. This self-service mechanism eliminates the need for manual ball retrieval, allowing continuous practice without interruption and resolving the time loss contradiction.

The patent employs adjustable leveling mechanisms (screw jacks or shims) that allow the mat to be dynamically adjusted to different floor heights and angles. This dynamic adjustment capability enables the putting surface to adapt to uneven floors while maintaining stability during use, resolving the contradiction between fixed stability and adaptive flexibility.
