Luggage case

Abstract

A luggage case includes a box-shaped frame formed of integrally molded polymeric material, and a retractable handle unit. The box-shaped frame includes a bottom portion having a plurality of openings and a surrounding wall portion upward extended from the bottom portion, and all edges of the box-shaped frame between the bottom portion and the surrounding wall portion are rounded edges. At least one of the rounded edges is provided with a recessed rib portion having two insertion holes provided thereon. The retractable handle unit includes two retractable bars that are inserted into the two insertion holes with two upper ends located outside the box-shaped frame to connect to a transverse grip portion, and two lower ends extended into a holding block located inside and connected to the box-shaped frame. Being supported by the box-shaped frame and the retractable handle unit, the luggage case has reduced weight but good structural strength.

Description

FIELD OF THE INVENTION[0001]The present invention relates to a luggage case, and more particularly to a luggage case that has an integrally molded inner supporting frame and therefore has increased structural strength but reduced weight.BACKGROUND OF THE INVENTION[0002]A traveler often uses a luggage case to conveniently hold personal items and clothes therein. To protect the luggage case against damage during travel, most of the currently available luggage cases are so designed that they have fixed shape and structural strength sufficient to resist forces externally applied thereto. The currently available luggage cases are also internally provided with binding straps or other holding means for holding personal items and clothes in place in the luggage cases.[0003]FIG. 1 is an exploded perspective view of a conventional luggage case, which includes an inner frame 90 and an outer enclosure 91. The inner frame 90 includes an upper shell 92, a lower shell 93, and supporting rods 94 co...

AI Technical Summary

Benefits of technology

The present invention is a luggage case with a reduced weight but increased structural strength. It has an inner supporting frame made up of a holding block, recessed rib, and retractable bars that support the case's designed shape and protect it from deformation. Compared to conventional cases, the luggage case has a simplified but strong frame that is easier to assemble and reduces manufacturing costs.

Problems solved by technology

An excessively heavy luggage case not only increases the user's burden in handling or moving it, but also reduces the quantity of things that can be held therein because all airlines place limit on the weight of luggage one can carry on to a flight with him.
