Height adjustment device for saddles or handlebars

A saddle and/or handlebar height adjustment device, comprising:

• a tubular element having one end fixed to a saddle and/or handlebar and another end coupled to a support element;
• a support element;
• a threaded ring coupling said tubular element to said support element, said threaded ring fixed to one of said tubular element and support element so as to be rotatable, and longitudinally fixed, with respect thereto and threadedly connected to the other of said tubular element and support element so as to be longitudinally adjustable with respect thereto upon relative rotation thereof;
• alignment means provided on said tubular element and support element for maintaining the relative rotational positions of said tubular element and support element upon relative rotation of said threaded ring and said other of said tubular element and support element to which said threaded ring is threadedly connected;
• whereby rotation of said threaded ring relative to said tubular element and support element results in longitudinal movement of said tubular element relative to said support element but no relative rotational movement between, said tubular element and said support element;
• and
• means for providing an audible indication of the longitudinal movement of a discrete distance of said tubular element relative to said support member upon rotation of said threaded ring.

A saddle and/or handlebar height adjustment device, comprising:

• a tubular element having one end fixed to a saddle and/or handlebar and another end coupled to a support element;
• a support element;
• a threaded ring coupling said tubular element to said support element, said threaded ring fixed to one of said tubular element and support element so as to be rotatable, and longitudinally fixed, with respect thereto and threadedly connected to the other of said tubular element and support element so as to be longitudinally adjustable with respect thereto upon relative rotation thereof;
• alignment means provided on said tubular element and support element for maintaining the relative rotational positions of said tubular element and support element upon relative rotation of said threaded ring and said other of said tubular element and support element to which said threaded ring is threadedly connected;
• whereby rotation of said threaded ring relative to said tubular element and support element results in longitudinal movement of said tubular element relative to said support element but no relative rotational movement between said tubular element and said support element;
• said alignment means includes an elongate alignment portion provided on one of the tubular element and support element and an aperture provided in the other of the tubular element and support element, said elongate portion and aperture having corresponding shapes and wherein said aperture receives said elongate portion;
• and
• wherein said elongate alignment portion is provided on said tubular element and said aperture is provided in said support element.
