Retractable wheel mechanism

摘要

A wheel retraction mechanism for use on travel luggage, the retraction mechanism causing the extension and retraction of one or more wheels upon relative movement of two adjacent members. The members comprise two engaging actuation surfaces which, upon relative longitudinal movement, create a movement in a different direction, which can be used to extend or retract wheels from a piece of travel luggage.

主权项

1. A wheel retraction mechanism for wheeled travel luggage, comprising:
a primary member having a first actuation surface extending from or along a longitudinally extending surface of the primary member; a secondary member, located substantially parallel to the primary member, the secondary member having a second actuation surface extending from or along a longitudinally extending surface of the secondary member; and at least one wheel, attached to the primary or the secondary member; wherein the second actuation surface engages the first actuation surface and is shaped so it is able to slide along the length of the first actuation surface, and the first actuation surface is shaped whereby relative longitudinal motion between the primary and secondary members results in rotation of at least one of the primary and the secondary members about its longitudinal axis, and wherein the first actuation surface is a slot, and the second actuation surface is a projection for engaging the slot.
