Abstract: A sports training device which allows for easy interchanging of weighted inserts. The sports training device includes a body, a handle, a contact zone, a inner chamber, a capping mechanism, and a weighted insert. The weighted insert attaches to the capping mechanism which can be attached the body of the device. The weighted insert is enclosed by the body within the inner chamber. The contact zone of the device can be equipment such as a baseball bat, softball bat, tennis racket, hockey stick, cricket stick, or any equipment used to strike a ball.

Abstract: A sport training apparatus for projecting a ball into the air for training an athlete in the proper technique of hitting or catching the ball. The apparatus includes ball projecting means and a spring connected thereto for movement between a cocked state and an actuated state. The spring is held in the cocked state by a partial vacuum automatically developed within an air chamber which is created when a piston enters a cylinder. To cock the apparatus for use, the ball projecting means is pushed down which, in turn, causes the piston to enter the cylinder and create the air chamber. A check valve is connected to the air chamber to provide unrestricted air exit from the air chamber as the piston enters the cylinder. A pneumatic control release is connected to the air chamber for allowing ambient air to enter the air chamber for releasing some or all of the partial vacuum to actuate the spring thereby causing the ball projecting means to propel the ball into the air where it can be hit or caught by the athlete.

Abstract: An apparatus for baseball batting training. The apparatus includes a rigid-wall cylindrical tube with means to support a baseball at one end thereof. A striker movable within the tube, is latched against a preselected force of a coil spring, and is rapidly urged toward the baseball for impingement therewith to propel the baseball upward a distance corresponding to the preselected force of the spring. When the striker is pushed down, a pin is visually extended and retracted to engage a selected one of a plurality of latching detentes to hold the striker in a cocked position. Upon release of the pin, the spring loaded striker is urged rapidly upward to impact with the baseball and propel the baseball into the hitting zone of a waiting batter. The inside diameter of the rigid-wall tube is larger than the small end of a baseball bat to allow the bat to be pushed into the tube and reset the apparatus for another use.

Abstract: The game includes a multi-sided hollow game box with an opening in the top thereof. A set of selector switches are arranged in a row on each side of the box, and a set of indicators are arranged in a similar row on each side of the box. The selector switches are positioned in registry with the indicators. The opening in the top of the box is provided with means for receiving a game card. The game card has a question printed on it as well as plurality of multiple choice possible answers, only one of which is correct. The game card has the correct answer coded thereon. A code reader is located within the box and is activated by the game card. The code reader is coupled to the indicators to energize those indicators corresponding to the correct answer. The selector switches have lights associated with them and when a switch is actuated its associated light will become energized and remain energized.
