Abstract

A golf swing practice, training and exercising club which is expressly designed for practicing and developing a well-timed rhythmically speed-controlled golf swing. It comprises a shaft having an upper end with a handgrip and which, generally stated, is comparable with a regulation or conventional handle-equipped shaft. The lower end is provided with a specially constructed head, that is, a ball-shaped head of predetermined diameter and weight. The ball has its upper axial portion bored and constructed to accommodate and fasten a shouldered reduced end portion of the shaft. The end portion of the shaft is screwthreaded to coact with a retaining nut located in an enlargement at the lower end of the bore. A counterbored portion constitutes a socket which opens through the bottom of the head and is lined and internally screw-threaded to accommodate insertable and removable weights held in place by a screw-threaded plug. The plug has a kerf to permit the same to be removed by a coin or a screwdriver.

Claims

1. A training club which is expressly designed and adapted for practicing an acceptably timed rhythmically controlled golf swing comprising:

a regulation shaft having an upper end provided with a handgrip and a lower end reduced in cross section and providing a shouldered screw-threaded head mounting shank, a ball-shaped head of predetermined diameter and weight, said ball having a bore including an upper end opening through an upper peripheral surface of said ball and a lower end communicating axially with an enlarged counterbore within said ball, said counterbore providing a socket and opening through a bottom peripheral surface of said ball diametrically opposite to said upper peripheral surface and fully and fittingly lined with an internally screw-threaded sleeve, said shank passing through said bore and having an assembling and retaining nut screwed on a coacting screw-threaded portion of said shank and abutting a bottoming surface of said socket and detachably mounting said head on said shank, variable weight media fitted removably and at will into said socket, and an accessible readily removable closure also mounted on said head, closing an outward open end of said socket and positioning said weight media retentively in a given place within the confines of said socket.

2. The training club defined in and according to claim 1 and wherein said socket is circular in cross section, is of a predetermined depth and transverse cross section, the weight media being characterized by at least one readily insertable and removable weighted disc of requisite material and of a diameter and thickness capable of fitting snugly but nevertheless insertably and removably in said socket, the closure comprising a marginally screw-threaded plug-like disc and said disc being manually screwed into the open end of the socket in such a way as to position and retain the weighted disc in a given functioning position within the confines of the socket.

3. The training club defined in and according to claim 1, and wherein said socket is circular in cross section and is of a predetermined depth and transverse cross section, said wEight media comprising a plurality of readily insertable and removable weighted discs of prescribed outside diameter which are snugly but insertably, selectively and removably fitted in said socket, and said closure comprising a marginally screw-threaded plug-like disc which is screwed into the open end of the socket in a manner to position and captively maintain said weighted discs in a given functioning position in said socket.
