Definitions

  • wheeled luggage includes one or more wheels integral with the frame of the luggage.
  • a retractable or foldable handle is provided to allow the luggage to be pushed or pulled along the ground. This alleviates the need for the user to carry and thus support the entire weight of the luggage.
  • a retractable panel has been provided which includes an extra wheel or two. The retractable panel is automatically deployed by pulling up on the handle. The extra wheels can be casters in order to increase the maneuverability of the luggage. Examples of such items are disclosed in United States Patent Nos. 5,519,919 and 5,568,848.

Abstract

On décrit un bagage comprenant une première série de roulettes (44, 46), et une deuxième série de roulettes (52, 54) pouvant être déployées ou non. Ledit bagage inclut une poignée (26) pouvant être placée en position rentrée ou en position sortie. L'utilisateur peut choisir de déployer ou non la deuxième série de roulettes même lorsque la poignée se trouve dans la position sortie. On décrit également un dispositif d'arrêt amélioré, ainsi qu'un système de roulettes (200). On décrit enfin un mécanisme à panneaux et roulettes pouvant fonctionner séparément soit avec un bagage, soit avec d'autres articles tels que chariots, diables ou landaus de bébé.
