Plastic adjustable roller skate

摘要

An adjustable roller skate has a front toe platform and a rear heel platform longitudinally behind the toe platform. One of the platforms is formed with a longitudinal extension telescoping in the other platform. Respective front and rear axles carried on the platforms in turn carry respective front and rear wheels. Respective toe and heel retainers on the platforms shaped to engage around the toe and heel of a foot on the skate are secured to this foot by at least one strap engageable over the foot in the retainers. A longitudinal row of teeth is formed on the extension and an elastic tongue is longitudinally nondisplaceable on the other platform and formed with teeth. This tongue is displaceable between a locking position with its teeth engaged in the teeth of the extension and thereby securing the two platforms against relative longitudinal displacement and a freeing position with its teeth out of engagement with the teeth of the extension and the two platforms relatively longitudinally displaceable. A pivotal latch dog is provided on the other platform for displacing the tongue between its positions and for releasably holding it in the locking position.
