DETAILED DESCRIPTION OF EMBODIMENTS

Attention is first directed to Figs. 1A to 8C, directed to a foldable suitcase according to the disclosure, generally designated 10. The suitcase 10 comprises a back wall 12, two parallely disposed side walls 14, a base wall 16, a front wall 18 and a top wall 20.

The back wall 12 is made of rigid material, or it can be rigidified by an associated rigid supporting panel articulated thereto, and likewise, the side walls 14 are either made of rigid material or are rigidified by an associated rigid supporting panel, as will be discussed and exemplified herein after. The base wall 16 too is a rigid wall panel.

The two side walls 14 are pivotally articulated to the back wall 12 by a 'living hinge' 24 extending along the common longitudinal back edge of the side walls 14 and the side edges of the back wall 12, whereby the side walls are foldable between an erect position (extending perpendicular to said back wall 12 and parallel to one another; Figs. 1A to 3), and a folded, collapsed position (disposed parallel to one another and flush against at least portions of an inside face 28 of the back wall 12; Figs. 4A-5D). Further noted, the back wall 12 of the foldable suitcase 10 is configured with a telescopic pull/push handle assembly 32, of known design (seen retracted in all Figs., save in Figs 10E and 10F), said telescopic handle assembly 32 is configured with a pair of telescopically retractable legs 34 disposed along the inside face 28 of the back wall 12 (though often concealed by a liner), and configured with a manipulating handle 38 projecting from a top portion thereof.

The rigid base wall 16 is configurable with a wheel set, which in the present example is a set of four double wheeled casters 40 (free rotational about a support pin articulable to the base wall 16), wherein said wheels 40 can be fixedly secured to the external face of the base wall 16, or detachably attachable thereto.

The top wall 20 is a flexible sheet, extending from the flexible front wall 18, and configured with a carrying handle 44, fabricated with the external face of the top face 20.

In the illustrated example, the foldable suitcase 10 is configured such that the entire setup, i.e. all the walls (12, 14, 16, and 20) are made of a continuous, single sheet, and further the top wall 20 continuously extends from a top edge 46 of the front wall 18. Accordingly, respective walls are attached along respective edges in a foldable manner, by so called 'living hinges', wherein the back edges of the side walls 14 are attached to side edges of the back wall 12 along edge 24, a back edge of the base wall 16 is attached to a bottom edge of the back wall 12 along edge 25, a bottom edge of the front wall 18 is attached to a front edge of the base wall 16 along edge 27, and a front edge of the top wall 20 is attached to a top edge of the front wall 18 along top edge 46.

However, it is appreciated that according to another example (not shown) the top wall can extend from a top edge of the back wall, whilst the front wall extends from a front edge of the base wall, and further wherein a front edge of the top wall is engageable by a closure to a top edge of the front wall.

The foldable suitcase 10 further comprises a closure arrangement configured for securing side edges 50 of the base wall 16 to bottom edges 52 of the respective side walls 14 (best realized in Fig. 4C). In the present examples, the closure arrangement is a zipper closure, continuously extending from two respect opposite sides, beginning at bottom back corner of the side walls (locations marked Z1 and Z2 in the drawings), along the bottom edge 52 of the side walls, further along the front edge 56 of the side walls 14, then onto the top edge 58 of the side walls and finally along a top edge portion 62 of the back wall 12, where two opposite zipper clasps 60 meet (location marked F in the drawings; best seen in Figs. 10E and 10F), though it is appreciated that since the closure zipper is continuous, the two zipper clasps can in fact meet at any location along the zipper path.

Once the closure, e.g. zipper, is closed, the foldable suitcase being at the erect position, the structure becomes solid with the side walls 14 and the base wall 16 rigidly extending from the back wall 12, thus obtaining a firm and stable volumetric body.

As mentioned herein before, at least the back wall 12, both side walls 14 and the base wall 16 are rigid, wherein such rigidity is either inherent to each of these wall panels, or imparted thereto by a rigidifying member. A rigidifying member can be attached to a respective panel, either fixedly or detachably, and can thus be pivotally articulated for facilitating manipulation of the suitcase between its erect position and the folded/collapsed position. In the example of Figs. 1 A to 8C, the back wall 12 and the base wall 16 are inherently rigid, whilst the side walls 14 are rigidified by collapsible support side panels 70 (best seen in Fig. 6A at a partially collapsed position; in Fig. 7A at the fully collapsed position; and in Figs. 8A and 8B at the erect position), wherein the support side panels 70 are rigid boards of material that at the erect position can be attached to an inside face of the side walls (e.g. by a hook and pile arrangement or other fastener), thereby supporting the side walls at the erect position and providing rigid walls such that the foldable suitcase can maintain its volumetric shape and stand at an upright position.

The foldable suitcase 10 is configurable between several positions. First is the erect, bodily position (e.g. as depicted in Figs. 1A to 1C). Second is a first collapsed position (e.g. as depicted in Figs. 4A to 4D) wherein the side walls 14 are folded over the back wall 12, whilst the base wall 16, the front wall 18 and the top wall 20 coextend from the bottom end of the back wall 12. At this position, the suitcase is the thinnest (corresponds with the maximal thickness of the back wall 12 and a single side wall 14 flush thereover) and this position can be suitable for storage e.g. by hanging in a closet, etc. Third is a second collapsed position (e.g. as depicted in Figs. 5A to 5D) wherein the side walls 14 are folded over the back wall 12 and in turn the front wall 18 and the top wall 20 are disposed over the folded side walls 14, with the base wall 16 coextending with the back wall 12 and a respective portion of the front wall 18 bearing against the base wall 16. At this position, the thickness of the suitcase corresponds with the accumulated thickness of the base wall 12, and the thickness of a single side wall 14 and the front wall 16, disposed flush over one another. If desired, the foldable suitcase 10 at either of the folded positions can be suspended from a hanger (not shown) and furthermore, a clasping arrangement can be configured (not shown) for retaining the suitcase at a folded position.

With further reference being made to Figs. 9A to 9E, there is illustrated an arresting arrangement according to an embodiment of the disclosure, wherein elements of the suitcase already disclosed hereinabove are identified by same reference numbers. The arresting arrangement is configured for selectively securing the base wall 16 at the erect position a substantially right angle with respect to the back wall 12 (Figs. 9A to 9D).

The arresting arrangement of Figs. 9A to 9E comprises a first locking member 80 articulated at a rear portion of the inside face of the base wall 16, said first locking member 80 being a rigid block member housing a pair of arresting plungers 82 oppositely arranged and spring biased to project laterally from the first locking member 80 through an opening 84, wherein the arresting plungers 82 are manipulable between a normally projecting position (Fig. 9B) and a manually contacted position (Fig. 9D), upon finger squeezing of manipulator slider grips 88 towards one another, in direction of arrows 85. A free end 91 of the arresting plungers 82 in chamfered (slanted) so as to facilitate easy and self-locking with respective locking location 92 configured as an opening at a bottom of second locking members being said telescopically retractable legs 34 of the handle assembly 32, said locking location 92 disposed in register with the arresting plungers 82 at the locked position (i.e. when the base wall 16 is at the erect position).

The arrangement is such that at the erect position (Figs. 9 A to 9D) the arresting plungers 82 are arrested within the locking location 92, thus preventing pivotal displacement of the base wall 16 with respect to the back wall 12. However, upon manipulating the slider grips 88 towards one another, the arresting plungers 82 retract and disengage from the locking locations 92 (Fig. 9C), whereby the base wall 16 can pivotally displace into the collapsed, unlocked position (Fig. 9E). Pivotal displacing (erecting) the base wall 16 into the fully erect position (disposed perpendicular to the back wall 12) entails spontaneous re-engaging of the arresting plungers 82 into the arresting locking locations 92. Arresting the base wall 16 at the erect position (with the arresting arrangement engaged respectively), gives rise to a rigid L-shaped chassis construction for supporting the entire suitcase erect and wherein the suitcase assumes a rigid and stable position rendering it suitable for carrying loads. Even more so, the base wall becomes articulated with the carrying handle assembly by engagement at the bottom portion of the telescopically retractable legs.

With further reference made back to Figs. 1A to 8C and to Figs. 10A to 10F, for exemplifying yet an arresting arrangement configurable for a foldable suitcase 10 according to an example of the disclosure, configured for supporting walls of the suitcase, namely side walls 14 and base wall 16, at an erect position with respect to the back wall

12.

As seen in some of the figures, and best in Fig. 4C, the foldable suitcase 10 is configured with yet an arresting arrangement comprising an arresting member 90 disposed over the base wall 16, at each side thereof, and each having a first edge 93 articulated to the bottom edge 52 of a neighboring side wall 14 through a living hinge, and a second edge 94 articulated through a living hinge along a portion of the base wall 16 and extending from a back corner of the base wall 16 (near location Z1 in the drawings) towards a front edge of the base wall 16, and wherein the length of the first edge 93 of the arresting member 90 does not exceed the depth of the base wall 16.

The arrangement is such that deploying the side walls 14 into the erect position, i.e. pivotal displacement in direction of arrows 95 (Figs. 4C and 10B) entails spontaneous displacement of the base wall 16 into the erect position, as illustrated in Figs. IOC and 10D.

In the illustrated example, the arresting member 90 is an isosceles right triangular member. However, it is appreciated that according to other designs the arresting member can assume other shapes. For example, the arresting member have a section of a triangular member, or be a rigid strap extending between the respective locations as described above.

The triangular arresting member in the illustrated example is an isosceles right triangular, wherein a hypotenuse thereof extending along a fold line 94 of the triangular member (extending from a bottom front corner of a side wall towards a front portion of the base wall).

As can best be seen in Figs. 4A, 4C 10A and 10D, the triangular arresting member 90 illustrated in the drawings is configured out of a rectangle member having a diagonal living hinge extending along a fold line 94 defining two triangular portions 97 and a second triangular portion 99, wherein the first triangular portion 97 overlaps a front-side portion of the base wall 16, and the second triangular portion 99 has a first edge 93 articulated to a bottom edge 52 of a side wall 14 through a living hinge, and a second side thereof is free. The first triangular portion 97 is fixedly secured over a respective portion of the base wall 16, e.g. by riveting, stitching, hook and pile fastener, adhesive, etc.

It is appreciated that a fabric liner can be disposed along at least inside portions of the walls of the foldable suitcase 10. It is appreciated that whilst in the example the back wall and the base wall are rigid, and the side walls are rigid (or rigidified), and that the front wall and the top wall are flexible, however wherein once the foldable suitcase is at the erect position and the closure arrangement is secured, the suitcase assumes a sturdy three dimensional shape, with the flexible walls tensioned between edges of respective rigid walls, thus imparting the suitcase a sturdy erect position. The arrangement is such that the closure arrangement (zipper in the illustrated example) serves to tension the flexible wall portions over the rigid walls and to give rise to the sturdy erect position.
