Portable utility surface

摘要

A portable utility surface appliance disposed on a top surface of a personal articles container engaging upright handles usually used for rolling the container (luggage) behind the traveler. An arrangement of attachments, cantilevers, and resilient leveling regions transform the uneven top-handled surface of the suitcase into a flush, substantially level working surface upon which personal articles, beverages, and electronic devices may be placed. The portable rigid utility surface appliance includes a utility surface adapted to bear on a personal articles container in a substantially horizontal position, a crossmember attached to the utility surface and adapted to extend between parallel uprights extending from the personal articles container, and a pair of opposed, elongated protrusions extending from the crossmember and adapted for simultaneous engagement with the uprights. The appliance further includes a leveling region on underside of the utility surface, to engage an uneven bearing surface on top of the luggage.

主权项

1. A portable rigid utility surface appliance comprising:
a utility surface adapted to bear on a personal articles container in a substantially horizontal position; a leveling region attached to an underside of the utility surface, the leveling region including a deformable granular substance adapted to engage surface discontinuities on an uneven bearing surface for maintaining stability of the utility surface, the leveling region configured to substantially conform to a top surface of the personal articles container for which the leveling region is adapted to engage; a crossmember having a distal end and a proximate end, the proximate end attached to the utility surface and the distal end adapted to extend between parallel uprights extending from the personal articles container; a downward annular slope defined by the crossmember, the downward annular slope extending from the proximate end and sloping below a plane defined by the utility surface, a distance of the downward annular slope based on accommodation of the surface discontinuities by the leveling region; and a pair of opposed, elongated protrusions extending perpendicularly from the crossmember and adapted for simultaneous engagement with the parallel uprights, the parallel uprights extending vertically from the personal articles container, each protrusion configured to engage a respective upright, the protrusions defining a brace extending parallel to a handle connecting an upper end of the parallel uprights; the defined brace and distal end configured for engagement and downward bias from retracted uprights resulting from disposing the handle adjacent to the brace; and the engaged, biased brace providing a cantilever for the utility surface by opposing downward force on the utility surface.
