Abstract
An automatic golf ball lifting device is inside the cylindrical cup; when switched-on can remotely, accurately and instinctively know the presence of a “on a hole” golf ball, hence a golf ball on its receiving plate situated approximately 4 inches ground depth, is mechanically raised on the ground level, lifting the golf ball continuously, for faster and easier access; wherein removal of the golf ball prompts the system to automatically lower the top receiving plate to its original position, in preparation for the next ball to be sensed and elevated.
Claims12
An automatic golf ball lifting device for lifting a golf ball within a golf hole comprising:
- a top plate having a diameter sufficient to substantially span a width of a golf hole diameter;
- a lift for moving the top plate between a first position and a second position raised relative to the first position for positioning the top plate at a level of a green surrounding the golf hole;
- a motor operatively connected to the lift for moving the lift between the first position and the second position;
- a load cell in communication with the top plate and motor;
- a printed circuit board configured to:
- receive load signals from the load cell indicative of a golf ball supported or not supported on the top plate, and
- provide actuation signals to operate the motor to move the lift from the first position to the second position when a golf ball is supported on the top plate, and move the lift from the second position to the first position when a golf ball is not supported on the top plate;
- and
- a battery for providing power to the printed circuit board, the motor and the load cell.
