Abstract: Golf putting practice devices and methods are described that can be used to practice putting indoors on a flat surface or in an opening in the floor. For example, some example golf putting practice devices described herein may include a ball receptacle, a frame, and a ramp. The ball receptacle has one or more walls defining a cavity sized to receive a golf ball. The frame has multiple openings to allow a flow of air when the device is placed over an opening in the floor, such as a duct outlet of a forced air circulation system. The ramp of the device may be adjustable between different lengths.

Abstract: A golf putting practice device adapted to serve as a substitute for a floor vent that fits into a floor duct of a forced air circulation system of a building and includes a cup shaped ball receiving enclosure and at least one flat support plate member extended outwardly from the ball receiving enclosure. A bottom of the receiving enclosure includes a ball return mechanism that ejects a ball from such enclosure. A plurality of apertures are formed in the support plate member to allow for air flow through the plate.

The front wall of the ball receiving enclosure includes a notched portion that provides a golf ball open access to the enclosure when the device is installed into a floor duct. A plurality of apertures are formed in the support plate member to allow for air flow through the plate.
