Abstract: A practice ball includes a ball having a hole bored partially therein. A flaccid material has a portion thereof disposed in the hole. A retainer is disposed in the hole along with the portion of the flaccid material to restrain the portion of the flaccid material in the hole of the ball.

Abstract: Golf balls with a reduced flight path are disclosed. In some cases, foam incorporated into a middle layer increases impact absorption and reduces a ball's flight path. In other cases, a dimple pattern may be selected to reduce a ball's flight path. In other instances, a parachute or other drag inducer may be deployed as a result of striking the ball to induce drag and minimize the ball's flight path.

Abstract: A golfer training aid for use in teaching a golfer how to square up the face of the golf club at impact resulting in golf shots having substantial accuracy. The device is a one-piece or multi-piece flat-face practice golf ball. The one-piece or multi-piece practice golf ball is shaped with a flat face 2 on one side. (FIG. 1B). The flat face has a 90-degree or right angle cut 4 to the radial portion or circular embodiment 3 of the semi-sphere 1. The importance of this unique feature is that it enables the golfer to position the flat side of the club face with the flat face of the practice golf ball and contact the ball flush and correctly. The flat face practice golf ball helps teach the golfer to hit a variety of controlled fades and a variety of controlled draws, a straight shot, as well as a backspin or descending blow, or a flop shot.

Abstract: A training golf ball apparatus designed to imitate the realistic feel, weight, acoustic and flight characteristic of a real (regulation standard) golf ball, to allow a golfer to practice the sport in a realistic way safely at home, includes mechanized flights concealed within a cavity of the golf ball; a lightweight ball component and a magnetized tee. The device will perform as well as a standard golf ball; give accurate feedback on performance and promote realistic training in the home environment. The device provides the illusion that a lightweight golf ball is of standard weight when it is placed on a tee. For safety reason, the training golf ball apparatus changes aerodynamic properties once leaving the golf tee, and behaves as a lightweight, high aerodynamic drag object once airborne.

Abstract: A training golf ball apparatus designed to imitate the realistic feel, weight, acoustic and flight characteristic of a real (regulation standard) golf ball, to allow a golfer to practice the sport in a realistic way safely at home, includes a mechanized shuttlecock; a lightweight ball component and a magnetized tee. When arranged functionally, the device will perform as well as a standard golf ball; give accurate feedback on performance and promote realistic training in the home environment. The device is engineered in such a way to give the illusion that a lightweight golf ball is of standard weight when it is placed on a tee. For safety reason, the training golf ball apparatus changes aerodynamic properties once leaving the golf tee, and behaves as a lightweight, high aerodynamic drag object once airborne.

Abstract: A practice putting kit and training method for practicing the aiming a golf ball, aiming the putter, and keep returning the putter to a square position to the golf ball. The kit includes a laser golf ball that produces a planar, laser beam of light. Printed on the outer surface of the golf ball is a centrally aligned reference line aligned with the laser. The laser is connected to a control switch, an optional timer, and a battery that enables the golfer to selectively control its activation. The golfer practices aiming the reference line at the target line and then uses the laser to verify if aiming was correct. The kit also includes a stand that holds the golf ball in an elevated position behind the golfer. During use, a standard putter and golf ball is placed in front of the golfer and the stand and laser golf ball are positioned behind the golf ball and aimed at the golf ball so that the laser beam illuminates the top of the golf ball and the target line.

Abstract: A compound ball simulates the performance of a regulation size baseball, softball, and golf ball. It is formed of spherical outer and inner shells dimensioned to abut one another or to provide a spacing between them. The outer shell is formed of molded polymeric material with circular apertures spaced over its surface. The inner shell is gas filled and resiliently rebounds in response to being compressed by the outer shell upon deformation of the outer shell in response to being hit, as by a bat or club. The apertures in the outer shell permit air to pass trough the apertures when the compound ball is in flight. The inner shell provides mass and impact rebound within the outer shell for simulating the action of a regulation ball when thrown, caught, hit or impacts an object. The outer shell may also contain raised dimpling to impart greater aerodynamic drag on the compound ball, further limiting its flight and range, or altering its performance.

Abstract: A simulated golf ball instructional device for use in practicing golf strokes which has a central body portion and two end portions. Each end portion has a length measured along the longitudinal axis of the device substantially equal to the radius of a conventional golf ball. The device has an overall length between about three and about five times the radius of a conventional golf ball. Satisfactory, improved and preferred overall lengths are disclosed, with the preferred overall length being substantially four times of radius of a conventional golf ball. One or both ends of the device have a generally hemispherical shape. The device is formed of a resilient, porous plastic open cell foam and is free of any covering skin that would substantially impede or prevent the passage of air from within the foam structure out into the space surrounding the simulated golf ball when a distorting force is applied to the device by a golf club.
