  • Patent number: 9592429
    Abstract: A tennis court ball retainer having a horizontally extending ball gutter along the tennis court back wall which has an upwardly facing channel dimensioned to receive and retain tennis balls. An upright flexible upper backdrop curtain coextends directly above and along the ball gutter for engaging tennis balls striking the upper curtain, thereby dampening the tennis ball impact and directing the engaged tennis balls to fall into the ball gutter for retention. A tennis court floor surface ball retainer is also provided and coextends with and under the ball gutter. The ball gutter extends a uniform distance above the tennis court floor surface and includes an upright flexible lower backdrop curtain coextending below and along the ball gutter for engaging and trapping tennis balls striking this lower curtain by rolling or skidding on the tennis court floor surface.

  • Patent number: 7094158
    Abstract: A compact, low profile golf putting practice apparatus includes a two-part flipper including a longitudinal flipping member and a coaxially mounted base section supporting the flipper member. A torsion spring pivots the flipper from its retracted position into an extended position whereby it propels a ball forwardly from a pocket area, and a powered retractor reversely pivots the flipper from its extended orientation into its retracted orientation. For safety, the two sections of the flipper are normally coupled together for movement as a unit by a resilient coupler which is capable of expanding temporarily when the flipper encounters an obstruction to its movement from the extended orientation to the retracted orientation.
