Abstract
Abstract A foldable luggage carrying device is disclosed which has relatively moveable frame members which enable the device to be convertible into multiple position for different uses. When used as a luggage carrier a second frame member is moved into position as an extension of the first frame member and luggage is carried on a luggage support at the bottom of the first frame member. The second frame member includes a seat unit and seat back so that if desired a user can place a support or prop on the ground so that the second frame member will be perpendicular to the first frame member to form a seat. If it is desired to carry the unit without luggage, the frame elements are moved into an inoperative position such that the support and both frame members are collapsed and locked together. This results in a compact and easy to carry unit.
