ABSTRACT:
An article of wheeled luggage having a pair of rear wheels for rolling engagement with an underlying support surface further includes a control rod located in close proximity to the front wall of the luggage and carrying a freely-rotatable front wheel at its bottom end and a pivotally-attached pull-handle at its top end. The control rod extends substantially vertically along at least a portion of the front wall and is axially rotatable so as correspondingly vary the orientation of the front wheel which is maintained in rolling engagement with the support surface. The control rod has a generally L-shaped construction including an upper leg extending along the front wall and a lower leg disposed proximate the bottom wall of the article of luggage, the front wheel being mounted in a predeterminately-fixed orientation on the lower leg. User-controlled variations in the intended direction of movement of the article along the support surface are transferred from the user-grasped pull-handle, through the control rod and to the front wheel to provide effective and substantially effortless steering of the article as the same is moved on and along the support surface.
