Golf training clubs

Abstract

A spring-loaded hinge for a training golf club comprises first and second hinge members (10, 20) pivoted to each other by a transverse pivot pin (30). Member (10) has a tongue (13) terminating in a generally circular arc (14) having a depression (15) therein, and member (20) has a pair of arms (23, 24) forming a fork between which the tongue (13) of member (10) is received, the pivot pin (30) passing through both arms and the tongue. Member (20) has an axial bore (25) containing a spring-loaded detent element (27) which bears against the circular arc (14) and engages in the depression (15). Member (20) is threaded externally at (43) towards the end opposite the pivot pin (30) and is slotted at (41) in the same region to provide communication with the bore (25) containing the spring (26). A threaded nut (42) engages with the screw thread (43) on the outside of that member (20) and a pin (40) passes through the slots (41) and engages with the end of the spring (26) in the bore (25) and with the nut (40), so that turning the nut (40) adjusts the spring tension. The nut conceals the pin (40) and slots (41), and the nut and the hinge member (20) adjacent thereto are marked (50, 51) to facilitate adjustment to desired settings.
