ABSTRACT:
An extendible roller skate has a support structure constituted by two mutually telescopic parts. Releasable fixing means are provided for securing the support-structure parts in fixed relative positions corresponding to a desired length of skate. These fixing means comprise a series of notches provided on one support-structure part, and a cooperating toothed member mounted on the other part of the support structure. This toothed member is mounted for movement towards and away from the notches of the notched support-structure part, movement towards the notches being opposed by a spring. A cam-shaped lever is provided to press the toothed member into engagement with the notches. Operation of this lever enables the rapid securing together and release of the two parts of the support structure.
