Apparatus for releasably locking an adjustable luggage handle

摘要

There is provided a wheel handle whose functional length is easily extended or shortened with respect to a wheeled luggage case. The wheel handle includes a handle grip mounted atop a pair of longitudinal tubes or rods slidable axially through a bezel fixed upon the luggage case. A mechanism including a minimal number of moving parts permits the user to lock and unlock the position of the extendible/collapsible wheel handle with the press of a spring-biased button. The button movement actuates a helical cam, which rotates a cam follower. Rotation of the cam follower extends or retracts a pair of sliding pins engageable into holes in the longitudinal handle tubes. With the button depressed against the force of the spring, the pins are withdrawn to allow adjustment of the effective handle length. Releasing the button, while the pins are aligned with a selected pair of apertures in the tubes allows the force of the spring to restore the button to its rest position, with the pins engaged into tube apertures to releasably lock the luggage handle in place.
