Abstract: The invention relates to a transporting system for items of luggage, in particular to a so-called wheeled case or trolley with releasable or exchangeable case elements. The transporting system for items of luggage comprises a rolling mechanism (10) and at least one item of luggage or case element (20), the rolling mechanism (10) having a wheel arrangement (11), a pulling device (12) and fastening means (13) for releasably connecting the item of luggage (20) to the rolling mechanism, and is characterized in that the fastening means (13), on the one hand, are connected to the rolling mechanism and, on the other hand, can be fixed in a releasable manner in an interior of the item of luggage (20). The fastening means may comprise, for example, touch-and-close fastener strips (13) which can be introduced into the interior of the item of luggage through slots (22) made in a rear wall (21) of the item of luggage (20), and can be fixed there on a touch-and-close fastener strip.

Abstract: Luggage, including a central part formed two mechanically strong, mutually linked half-frames that support two trays defining the central space of the luggage. A connecting frame (40) is mounted between each half-frame and an associated tray and is fitted with a channel (41) within which the tray is affixed by appropriate fasteners. Using the same central parts and connecting frames, a plurality of diverse suitcases or briefcases may be implemented using other trays such as soft trays and.as a result manufacturing costs may be lowered.

Abstract: The invention relates to a suitcase with interchangeable case-shells, the central part of which (10) includes two stable half-frames (20, 30) bearing one against the other. Said half-frames (20, 30) are used as supports for the two case-shells (41, 42) of the suitcase. Each shell is detachably connected to the half-frame (20, 30) assigned to it. In order to ensure mutual support of the load, each shell (41, 42; 51, 52) edge is extended, at least in partial portions, by a flange (43, 44) the length of which is chosen so as to ensure that, when the suitcase is closed, the flange of the first shell (41; 51) and the flange (44) of the second shell (42; 52) abut against each other.

Abstract: This invention relates to a case with a variable capacity, comprising a central part (10) which has two stable frame halves (20,30) hinged to one another which serve as supports for a single pair of various size sheet pairs (41,42;51,52) defining the interior of the case, the shells (41,42;51,52) being detachably connected to the frame halves (20,30) of the central part (10), so that shells of different depths may be used together with the same central part. The invention also relates to a set of cases, comprising a central part and two or several pairs of shells.
