  • Automatic cordless golf ball return
    Patent number: 5165690
    Abstract: An automatic ball return for practicing golf putting includes a ramp that receives the putted ball, converts the energy of the rolling ball into vertical movement up the ramp, and then through gravity, rolls the ball back down the ramp towards the user. Two legs attached to the ramp are interlocked when the device is in use to provide the proper contour to the ramp, and disengage so the legs and ramp lie flat when the device is to be stored or transported. The ramp includes a target on each end, and the device may be positioned with either leg along the ground allowing either target to be used.
