In this particular example, the peripheral edge 32 is attached to the peripheral edge 34 of the peripheral wall 20 along the trailing edge 32, and the leading edge 38 of the peripheral side wall 30 is connected to the peripheral edge 40 of the peripheral wall 26 at the connecting portion 27 (FIGS. 5A to 5A). 6), the leading edge 38 of the peripheral side wall 30 is with the peripheral edge 40 of the peripheral wall 26 by a zipper fastener 42 (FIGS. 2A-2C) extending along the entire leading edge 38 except for the connecting portion 27. Engageable. The zipper fastener 42 includes a front zipper tape 44 attached to the peripheral edge 40 of the peripheral front wall 26 and a rear zipper tape configured on the front edge 38 of the peripheral side wall 30 (the rear zipper tape is integrated with the front edge 38 of the peripheral side wall 30). Or can be incorporated into the leading edge 38 of the peripheral side wall 30). A pair of zipper pull tabs 45 are provided to open and close the zipper 42. It should be noted that the specific example refers to the connection of the flexible peripheral side wall 30 to the peripheral anterior wall 26 of the anterior shell, but this is merely an example. It should be understood that the present disclosure also includes an alternative device capable of connecting the flexible peripheral wall to the peripheral posterior wall beside it via a connecting portion located on the periphery of the posterior peripheral wall and a zipper device. ..

Although not shown, the suitcase can be configured with a deployment mechanism by configuring a zipper in the flexible gusset portion of the peripheral wall 30, thereby opening the zipper to the width of the peripheral wall 30. When the zipper is closed, the peripheral side wall 30 contracts.

It is understood that one or both, the front base 24 and the rear base 18 can be provided with one or more closed openings (not shown), one or more closed openings into the space of the suitcase. Can be easily accessed. Such a closureable opening may be added to or replace the peripheral wall fastener.

One or both, front and rear bases can include one or more soft portions (not shown). The soft portion can be integrated with the rigid shell, or the soft portion can be added to the rigid shell by a closure system, eg, a zipper fastener, to the space inside the suitcase. Make access easier.

A pair of wheels 48 are connected to the bottom of the rear shell 12, the wheels 48 can be free-swing wheels or wheels, and the flat support base 50 comprises an outer portion 50A and an inner portion 50B. The inner portion 50B is fixedly disposed in the suitcase as discussed below.

The suitcase is further configured with a telescopic handle disposed on the rear shell 12, which in this example has two telescopic rods 60 (see, eg, FIGS. 1B, 2B, 2D) and a telescopic rod. It is provided with a handle 62 arranged at the upper end of the. The telescopic handle is operable between the retracted position (FIGS. 1B, 2B, 2D, etc.) and the retracted position (FIG. 8) used to advance the suitcase 10. In the retractable position of the telescopic handle, the handle 62 is arranged so as to be accommodated in the recess 64 on the top rear surface of the rear shell 12, so that the handle 62 does not project above and behind the surface of the rear shell 12. Similarly, the telescopic rods 60 are each accommodated within a support guide tube 63 that is more securely secured within the longitudinal recess 65 of the rear base 18, whereby the guide tube 63 is flush with the rear surface of the rear base 18. Above (ie, the recesses project on the inner surface 19 of the rear base 18).

As an alternative (not shown), the guide tube can be configured on the inner surface 19 of the rear base 18, and the telescopic rod extends through a suitable opening at the top of the peripheral rear wall 20 of the rear base 18.

Further noteworthy, the peripheral side wall 30 is configured together with a carrying handle 31 at the top thereof and a carrying handle 33 at the side (FIG. 8). The carrying handle can be made of flexible material or can be rigid. However, since the carrying handle is configured on the outer surface of the peripheral side wall 30, the carrying handle is folded inward when the suitcase is folded, as will be discussed later herein. Furthermore, the peripheral side wall 30 can be configured with one or more storage pockets on the outer surface (indicated by 37A) and / or the inner surface (indicated by 37B) of the peripheral side wall 30.

The peripheral wall 30 is further configured with one or more support parts 66 at the bottom of its outer surface, whereby the suitcase 10 is wheeled when placed in its upright position in the unfolded position of the suitcase 10. Supported by 48 and the one or more support parts 66, it keeps the suitcase horizontal and stable. The support part 66 is made of a rigid material, but in the folded position of the suitcase, the support part 66 is completely accommodated in the space of the suitcase and does not project or interfere.

In that unfolded position, one or more rigid support plates, generally represented by 70, are coupled to the inner portion of the rear shell 12 to provide stability to the suitcase and maintain a substantially rectangular shape. (See FIGS. 5A-8). The rigid support plate 70 is made of a non-flexible material and is connected at the inner surface of the peripheral rear wall 20 (or to the inner surface 19 of the rear wall 18) through the flexible connecting swivel shaft 72 (FIGS. 7A and 7B), and in the unfolded position. The rigid support plate 70 is arranged in close contact with the corresponding portion of the peripheral side wall 30. The support plate 70 is removable and mountable on the inner surface of the corresponding peripheral side wall 30 by a separable fastening mechanism such as, for example, hook and pile fasteners (Velcro ™), snap fasteners and the like.

The bottom rigid support plate 70 extends at the bottom base of the suitcase 10, and in the folded position, the bottom support plate 70 is arranged in close contact with the inner surface 19 substantially parallel to the rear base 18 and is in the unfolded position. The bottom support plate 70 is configured to be arranged substantially perpendicular to the rear wall 18 and in close contact with the corresponding inner bottom portion of the peripheral side wall 30. Similarly, the additional support plates (top and side support plates) are composed of the top base and side walls of the suitcase 10, and at the folded position, the additional support plates are arranged substantially parallel to the rear base. In the unfolded position, the support plate is configured to be arranged so as to be substantially perpendicular to the rear wall and in close contact with the corresponding inner top portion and side wall portion of the peripheral side wall 30.

In the unfolded position, one or more support plates reinforce the flexible perimeter, giving the suitcase stability in the unfolded position and ensuring the overall rectangular shape of the suitcase 10.

An important feature of the suitcase according to the present disclosure is the thickness ratio between the unfolded position and the fully folded position of the suitcase 10. Therefore, the structure is such that the plane occupied area of the front shell 14 is slightly larger than the plane occupied area of the rear shell 12, whereby the peripheral front wall 26 is the peripheral rear wall at the folded position (FIGS. 1A to 1C and 3A to 3E). The peripheral edge 34 of the 20 is accommodated, and the thickness T of the suitcase 10 in the folded position coincides with the height H) of the rear shell 12 and the thickness t of the front base 24.

The term "occupied area" refers to the planar size of a shell member. Therefore, it is clear that the front shell 14 is larger than the rear shell 12, and in the folded position, at least a part of the peripheral rear wall 20 is covered by the peripheral front wall 26 with the inner surface 19 of the rear base 18 and the inner surface 29 front base 24. The space S has a height h substantially equal to the height of the peripheral rear wall 20, and further, in the folded position, the space S is the peripheral side wall 30 and the first. It completely accommodates all other components discussed, such as the members of the inner portion 50B of the wheel support, the longitudinal recess 65, and the like. In the folded position, the peripheral edge 34 of the peripheral rear wall 20 substantially abuts on the inner surface 29 of the front base 24.

At the unfolded position of the suitcase, there is an expanded storage space S'between the inner surface 19 of the rear base 18 and the front base 24 of the inner surface 29, in which the peripheral side wall 30 is fully unfolded, and the expanded storage is described. The space S'has a thickness corresponding to the height of the peripheral front wall 26 and the width of the peripheral side wall 30 and the cumulative height of the peripheral rear wall 20.

Folding the suitcase 10 from its unfolded position to its folded position involves pulling one or more support plates 70 away from the inner surface of the peripheral side wall 30 and folding the support plates 70 inward (in the direction of arrow 79) to support them. This is done by placing the plate 70 against the inner surface 19 of the rear wall 18. The peripheral side wall 30 can then be bent inward into the space S', and then the two shells 12 and 14 are pressed against each other until a fully folded position is obtained, and the peripheral edge 34 of the peripheral wall 20 is , Substantially abuts on the inner surface 29 of the front base 24. Deployment of the suitcase 10 to its fully expanded position is performed in reverse order, i.e., first, the two shells 12 and 14 are moved away from each other and the peripheral side wall 30 is fully expanded and extended. Then, one or more support plates 70 are spread outward (opposite direction of the arrow 79) and the support plate 70 is fixed to the inner surface of the peripheral side wall 30, whereby the suitcase 10 is ready for use.

According to one particular example, the total thickness of a suitcase relates to the size of carry-on baggage / baggage / carry-on bag, which, in its unfolded position, defines a maximum thickness (depth) of 25 cm (10 inches). The guidelines set by the International Air Transport Association (IATA) can be met, while in the folded position the thickness can be configured not to exceed about 6 cm. However, this is a specific example and it is understood that the present disclosure applies to any size of suitcase.
