Abstract
A golf club or part thereof may include a ball-strike head 1, a hosel 2 having a shank 5 that extends along at least part of, and that engages with, the head, biasing means (eg a spring 9) that provides a locking force that seeks to move the head 1 and hosel apart 2 and, in doing so, causes the head to remain locked in one or other of a selection of loft settings 4. The club or part thereof being such that hand force can be applied to move the head 1 inwards to overcome the locking force to free the head to be turned into another of the loft settings 4. The arrangement is such that subsequent reverse movement of the head will cause it to be locked in that other setting.
Claims18
A golf club or part thereof, comprising:
- a ball-strike head having a toe end;
- a hosel having a shank that extends along at least part of, and that engages with, the head;
- and
- biasing means that provides a locking force that seeks to move the head and hosel apart and, in doing so, causes the head to remain locked in one or other of a selection of loft settings;
- the golf club or part thereof being such that hand force can be applied to move the head inwards to overcome the locking force to free the head to be turned into another of the loft settings, and such that subsequent reverse movement of the head will cause it to be locked in that other setting;
- wherein the head has a series of locking teeth and the hosel has a series of locking teeth, these being arranged such that they intermesh to lock the head in any of the loft settings and subsequently disengage when the head has been moved by hand to overcome the locking force to enable the head to be turned to another of the loft settings;
- and
- the two series of locking teeth are in a male-female engagement wherein the teeth of the hosel are male and the teeth of the head are female, and each set of teeth is formed to have a substantially conical shape and tapers outwards in the direction of the toe end, such that when the golf club is swung in a normal golf swing, a centrifugal force from the swing urges the teeth of the head tighter against the teeth of the hosel resulting in locking effect.

A golf club, comprising:
- a ball-strike head having a toe end and a cone shaped series of locking teeth arranged such that each of these teeth extend in a straight line;
- a hosel having a cone shaped series of locking teeth arranged such that each of these teeth extend in a straight line that compliments the cone shaped series of locking teeth of the head, and a shank that extends along at least part of, and that engages with, the head;
- biasing means that provides a spring locking force that seeks to move the head and hosel apart and, in doing so, causes the head to remain locked in one or other of a selection of loft settings;
- each of said cone shaped series of locking teeth tapers outwards in the direction of the toe end, the two series of locking teeth being arranged such that the cone shape of one sleeve-fits into the cone shape of the other in a meshed male-female relationship to lock them against rotation, and such that when the golf club is swung in a normal golf swing, a centrifugal force from the swing urges the series of teeth of the head tighter against the series of teeth of the hosel resulting in a locking effect, and wherein hand force can be applied to move the head inwards to free the head to be turned into another of the loft settings, and such that subsequent reverse movement of the head will cause it to be locked in that other setting.
1 more element
A golf club or part therefor, having a toe end and a heel end, comprising:
- a) a ball-strike head integral with or secured to a first locking gear comprising splines;
- b) a hosel integral with or secured to a second locking gear comprising splines;
- and
- c) slip gears having a plurality of teeth;
- the club or part therefor being formed such that:
- the head and the hosel engage one another to releasably lock the head in one of a plurality of loft settings;
- a first spring force acts on the locking gears to bias them to engage one another;
- a second spring force acts on the slip gears to bias the teeth of one slip gear to engage with teeth of another;
- hand force can be applied to the head to move it towards the heel of the club against the bias on the locking gears to unlock the head so that it can be hand rotated into another of the loft settings and then released such that the same bias causes the head to be locked in that other loft setting;
- as the head is rotated into said other loft setting at least one of the slip gears rides over another of them to generate a click sound and/or a tactile indication to give a person adjusting the club audible and/or tactile feedback of the adjustment;
- and
- wherein the first spring force that acts on the locking gears and the second spring force that acts on the slip gears is provided by a common spring.
