Abstract: A physical training unit comprising a tethered ball adapted for facilitating practice of a sport swing beneath a basketball hoop. The swinging motion for sporting activities such as baseball, tennis and golf may be addressed by the suspension of a ball from a tether in a configuration simplifying both the installation, removal and retrieval of the tethered ball relative to the hoop.

A tubular member of defined length is inserted over the tether and permits the pivotal actuation of the tether upon impact of the ball by the user and the limited motion thereof due to interaction with the basketball hoop as well as the limited movement of a free end of the tether relative to the tubular member. In this manner, a variety of athletic swings can be practiced from a conventional basketball hoop assembly.

Abstract: A tossing and catching play object in the shape of a ball or flying disc, made of a relatively malleable rubber or plastic material, having animal limb shaped appendages extending outward from the surface of the play object.

Abstract: The tilt switch/incline indicator of the invention consists of a first support member that is connected to the game cabinet in a known orientation. A second member is pivotably supported on the first member and can be fixed relative thereto at angles corresponding to the desired angle of incline of the playfield. The second member supports a pendulum-type tilt switch similar to that used in the prior art. The pendulum acts like a plumb line to give a visual indication to the game operator that the playfield is at the desired angle set at the second member by observing when the pendulum is centered relative to the contact. The mechanism of the invention uses the tilt switch as the level indicator such that the playfield can be positioned at a known angle without requiring a separate level indicator or the recalibration to the tilt switch.

Abstract: A practice golf club is presented. In accordance with the present invention, the practice golf club comprises upper and lower shafts connected by a one-way hinge. The one-way hinge is located near the lower end of the club. The upper shaft has a grip at its upper end and the lower shaft has a head at its lower end.

(i.e., in the reference plane of the club face) to about 45.degree.. During use of this practice club, the hinge will pivot mirroring the correct wrist position of the golfer during a correct golf stroke. Therefore, during the backswing of a correct swing, the hinge will break or pivot and remain so pivoted through most of the downswing as will the golfer's wrist.
