Document Type and Number:
Japanese Patent JP2002534238
Kind Code:
A
Abstract:
A member (e.g. baseball bat) includes a switch manually operable to obtain the transmission of signals by a transmitter in the member to an apparatus for propelling an element (e.g. ball) toward an individual holding the member. The apparatus includes a receiver for receiving the transmitted signals and includes a housing with a hollow passage. A ramp supported on the housing holds a plurality of the elements for sequential movement into the passage. The element in the passage is supported on one of the fingers of a rotary detainer. The detainer is normally prevented from rotating by a release mechanism coupled to the detainer. The detainer is rotated by the weight of the element when the release mechanism is decoupled from the detainer upon the reception of the transmitted signals. The element then moves downwardly in the passage to a propulsion mechanism which may comprise a pair of rollers for gripping the opposite ends of the element. The rollers are actuated by motors connected in a circuit with a transportable energy source (e.g. battery) so that the motors are energized only when a ball is disposed on a finger in the detainer, thereby prolonging battery life. The element is propelled by the propulsion mechanism toward the individual holding the member so that the individual can practice receiving the element (e.g. hitting the ball). The trajectory of the propelled ball can be adjusted by pivoting the housing relative to a base member which supports the housing and which holds the battery.
