Embodiment Construction

[0012] According to the drawings, the suitcase 1 includes an upper frame 2 and a lower frame 3, which are fixedly mounted on an upper shell 4 and a lower shell 5, respectively.

[0013] Only one of the upper frame 2 and the lower frame 3 is described here, which means that, in a preferred embodiment, both the frames 2 and 3 of the suitcase 1 have all the features described below.

[0014] From figure 2 and image 3 It can be seen that the frame 2 contains a plurality of corner areas 6, four in this embodiment.

[0015] Two consecutive corner regions 6 define a side 7 of the suitcase 1 . In other words, each corner region 6 is a frame portion having a much smaller radius of curvature than the adjacent sides (which do not need to be absolutely straight) ).

[0016] The frame 2 comprises a generally U-shaped base (not visible in the figures) to which the edge 8 of the casing 4 is glued. The base also includes a plurality of components for guiding the edge 8 to insert itself...

Abstract

The present invention relates to a suitcase (1) comprising a first shell (4) and a second shell (5) articulated to each other, at least one frame fixedly connected to the first and second shell (4, 5), in which the frame, formed by injection molding has an overall structural strength which is higher than the prior art frames.

Description

technical field [0001] The present invention relates to a suitcase and a method of making a suitcase frame. Background technique [0002] Suitcases for holding clothes and / or personal items are known in the art. For example, the applicant's European patent EP 1867246 discloses a suitcase comprising two frames hinged together with corresponding shells connected thereto to define the interior volume of the suitcase. [0003] A rigid frame with a constant cross-section is basically extruded. However, the manufacturing method of injection molding can produce such products at a lower cost. [0004] However any injection molded frame will necessarily lack complete uniformity which is reflected in the final product as structural weaknesses. This structural defect can only be corrected by increasing the size of the frame itself, but doing so increases the weight of the frame. [0005] In view of the prior art described above, the object of the present invention is to provide a s...
