Patent attributes
A training bat apparatus includes a shaft and audible and visual swing quality indicators on the shaft. The audible indicator includes a sound-producing body affixed to a barrel portion of the shaft, and an impact-producing body movably mounted along the shaft so as to strike the sound-producing body and produce a noticeable sound in response to the training bat apparatus undergoing a dry swing relative to a pitched ball. The visual indicator is provided in a radial position along a longitudinal side, and relative to a longitudinal axis, of the shaft for enabling placement of a batter's hands in a given proper tandem grip about a handgrip portion of the shaft. Provision of these indicators and their functioning enable the batter to undergo effective dry batting training using the training bat apparatus in conjunction with a pitcher and catcher undergoing respective pitching and receiving training in a bullpen session.
