Abstract
A collapsible sports racket comprising, in accordance with one aspect of the present invention, a shaft having a mounting member extending from one end and a grip handle extending from the other end; a head having a neck with a receptacle for receiving the mounting member; a threaded member slidably disposed along the mounting member for rotational engagement with a threaded collar on the neck so as to releasably secure the head to the shaft; radially disposed projections mounted to the member for restricting rotation of the shaft with respect to the neck along its longitudinal axis upon engagement with the receptacle; and guideways in the receptacle for receiving the projections upon engagement of the mounting member with the receptacle so as to limit longitudinal rotation. In the alternative, the coupling assembly of the present invention comprises a link member pivotally mounted to the mounting member such that the shaft may pivot about the racket head, and a guideaway in the neck adapted for receiving the link member; the link member having pins at one end adapted for pivotal engagement with grooves in the guideway to facilitate the pivotal movement of the shaft about the head.
