ABSTRACT:
A ball and elastic cord is affixed to a finger band so that the ball may be thrown, retrieved and paddled by a user's hand. A finger band comprising a strip wrapped about and secured to a finger by locking means such as frictional fabric pads hold the cord snugly about a finger. The cord is firmly secured while permitting adjustment of cord length by threading through apertures in stiffened plates on opposite sides of the strip. The ball in one embodiment has a fabric cover internally filled like a bean bag with plastic pellets and contains a semi-spherical internal cup anchor for securing the cord to the ball. An electronic circuit with a spring biased switch responds to a predetermined force threshold on the cord for signalling by audio or visual means identifying different balls to be used in various games. One or more photo-diode lamps thus can identify one of several balls or players directly or by means of shaped decals, etc. A translucent ball cover may respond by fluorescence to light to store the signal after a momentary switch contact. The ball is manipulated in game steps to actuate the signal by the magnitude of force on the ball at the end of a throw or in response to external forces by contact with another player's ball or cord.
