DETAILED DESCRIPTION OF EMBODIMENTS
Attention is made to the annexed drawings showing an example of a collapsible
suitcase according to this disclosure, generally designated 10, deployable
between a
collapsed position (Figs. 1A ¨ 1C and 3A to 3E), and an expanded position
(Figs. 2A to
2F and 4A to 8).
The suitcase 10 comprises a back shell 12 and a front shell 14, both shells 12
and 14 made of a non-pliable, rigid material, such as molded polymeric resins,
composite materials etc. The back shell 12 is configured with a substantially
flat back
base 18 and a perimetric back wall 20 extending upwards therefrom. The front
shell 14
is configured with a substantially flat front base 24 and a perimetric front
wall 26
extending upwards therefrom.
A flexible perimetric side wall 30 of the suitcase is made of flexible
material
such as fabric, synthetic materials e.g. flexible plastic, rubber, etc., with
or without
reinforcements, is attached, e.g. by stitching, welding, adhering, etc., in
this specific
example, along a back edge 32 thereof to a perimetric edge 34 of the
perimetric back

wall 20, with a front edge 38 of the perimetric side wall 30 articulated to a
perimetric
edge 40 of the perimetric front wall 26 at articulation portion 27 (better
seen in Figs.
5A-6), and the front edge 38 of the perimetric side wall 30 is engageable with
the
perimetric edge 40 of the perimetric front wall 26 by a zipper fastener 42
(Figs. 2A to
2C) extending along the entire front edge 38 excluding the articulation
portion 27. The
zipper fastener 42 comprising a front zipper tape 44 attached to the
perimetric edge 40
of perimetric front wall 26, and a back zipper tape configured at the front
edge 38 of the
perimetric side wall 30 (said back zipper tape can be integral with or
integrated with the
front edge 38 of the perimetric side wall 30). A pair of zipper pull tabs 45
is provided,
for closing/opening the zipper 42. It is noted that although the specific
example refers to
articulation of the flexible perimetric side wall 30 to the perimetric front
wall 26 of the
front shell, this is but a mere example; it is to be understood that this
disclosure also
encompasses alternative arrangements in which the flexible perimetric side
wall can be
articulated to the perimetric back wall by via an articulation portion and a
zipper
arrangement located at the perimetric edge of the back perimetric wall.
Whilst not illustrated, the suitcase can be configured with an expansion
mechanism, by configuring a zipper over a flexible gusset portion at the
perimetric side
wall 30, whereby opening said zipper enlarges the width of the perimetric side
wall 30,
and closing said zipper contracts the perimetric side wall 30.
It is appreciated that one or both the front base 24 and the back base 18 can
comprise one or more closable openings (not shown), wherein the one or more
closable
openings can facilitate access into the space of the suitcase. Such closable
openings can
be in addition or instead a fastener at the perimetric side wall.
Either or both the front base and the back base can comprise one or more soft
portions (not shown). Said soft portions can be integrated with the rigid
shell or they
can be applied thereto by a closure system, e.g. a zipper fastener,
facilitating access to
the inside space of the suitcase
A pair of wheels 48 is articulated at a bottom portion of the back shell 12,
said
wheels 48 can be free swivel wheels or roller wheels, with a flat support base
50
comprising an outside portion 50A and an inside portion 50B, the latter
fixedly disposed
within the suitcase, as will be discussed hereinafter.
The suitcase is further configured with a telescopic handle disposed at the
back
shell 12, said handle comprising, in the present example, two telescopic rods
60 (e.g.
CA 03107400 2021-01-22
WO 2020/031173 PCT/IL2019/050866
- 11 -
seen in Figs. 1B, 2B, 2D) and a handle 62 disposed at the top end of the
telescopic rods.
The telescopic handle is manipulable between a retracted position (Figs. 1B,
2B, 2D,
etc.) and an extracted position (Fig. 8) used for rolling along the suitcase
10. The
arrangement is such that at the retracted position of the telescopic handle,
the handle 62
is received within a depression 64 at a top back face of the back shell 12,
thus it does
not project above and behind the surface of the back shell 12. Likewise, the
telescopic
rods 60 are each received within a support guide tube 63 which in turn is
fixedly
secured within a longitudinal recess 65 at the back base 18, such that the
guide tubes 63
are flush with the back surface of the back base 18 (i.e. the recesses project
at an inside
face 19 of the back base 18).
As an alternative (not shown), the guide tubes can be configured at the inside
face 19 of the back base 18, with the telescopic rods extending through a
suitable
opening at the top portion of the perimetric back wall 20 of back base 18.
Further noted, the perimetric side wall 30 is configured at a top portion
thereof
with a carrying handle 31 and with a side carrying handle 33 (Fig. 8). Said
carrying
handles can be made of pliable material or they can be rigid. However, as they
are
configured over the outside face of the perimetric side wall 30, they collapse
inwards
upon folding the suitcase, as will be discussed herein after. Furthermore, the
perimetric
side wall 30 can be configured with one or more storage pockets, at an outside
face
(designated 37A) and/or an inside face (designated 37B) of the perimetric side
wall 30.
The perimetric side wall 30 is further configured at bottom portion at the
outside face thereof with one or more support pieces 66, whereby at the
expanded
position of the suitcase 10, when placed at its upright position, it is
supported by the
wheels 48 and said one or more support piece 66, maintaining the suitcase
level and
stable. Though one or more support pieces 66 are made of rigid material, at
the
collapsed position of the suitcase they are fully received within the space of
the suitcase
and do not project or interfere.
In order to render the suitcase stability and maintain a substantially
rectangular
shape at its expanded position, one or more rigid support boards, collectively
designated
70, are articulated at inside portions of the back shell 12 (seen in Figs. 5A
to 8) . The
rigid support boards 70 are made of non-pliable material, and are articulated
at an inside
face of the perimetric back wall 20 (or to the inside face 19 of back wall 18)
through a
flexible connecting pivot 72 (Figs 7A and 7B), wherein at the expanded
position said
CA 03107400 2021-01-22
WO 2020/031173 PCT/IL2019/050866
- 12 -
rigid support boards 70 are be disposed flush against corresponding portions
of the
perimetric side wall 30. The support boards 70 are detachably attachable to
inside face
of the corresponding the perimetric side wall 30 through a detachable
fastening
mechanism, e.g. a hook and pile fastener (VelcroTm), snap fasteners, etc.
A bottom rigid support board 70 extends at a bottom base of the suitcase 10,
and
is configured such that at the collapsed position said bottom support board 70
is
disposed substantially parallel to the back base 18 and flush against the
inside face 19,
and at the expanded position said bottom support board 70 is disposed
substantially
normal to the back wall 18 and flush against a corresponding inside bottom
portion of
the perimetric side wall 30. Likewise, additional support boards (top and side
support
boards) are be configured, at a top base and side walls of the suitcase 10,
and are
configured such that at the collapsed position said additional support board
is disposed
substantially parallel to the back base, and at the expanded position said
support board
can be disposed substantially normal to the back wall and flush against
corresponding
inside top portion and side wall portions of the perimetric side wall 30.
At the expanded position the one or more support boards reinforce the flexible
perimetric side wall and impart the suitcase, at the expanded position, with
stability and
secure the overall rectangular shape of the suitcase 10.
An important feature of the suitcase according to the present disclosure is
the
ratio of thickness between the expanded position and the fully collapsed
position of the
suitcase 10. Thus, the arrangement is such that the planar footprint of the
front shell 14
is slightly greater than a planar footprint of the back shell 12, whereby at
the collapsed
position (Figs. 1A- 1C and 3A to 3E) the perimetric front wall 26 accommodates
the
perimetric edge 34 of the perimetric back wall 20, and wherein the thickness T
of the
suitcase 10 at the collapsed position corresponds with a height H) of the back
shell 12
and a thickness t of the front base 24.
The term footprint refers to the planar size of the shell members. It is thus
noticeable that the front shell 14 is larger than the back shell 12, and at
the collapsed
position at least a portion of the perimetric back wall 20 is enveloped by the
perimetric
front wall 26, giving rise to a space S extending between an inside face 19 of
the back
base 18 and an inside face 29 the front base 24, said space having a height h
substantially corresponding with a height of the perimetric back wall 20, and
further
wherein at the collapsed position said space S entirely accommodates the
perimetric
CA 03107400 2021-01-22
WO 2020/031173 PCT/IL2019/050866
- 13 -
side wall 30, as well as all other components discussed hereinabove, e.g.
inside portion
50B member of wheel supports, longitudinal recess 65, etc. At the collapsed
position
the perimetric edge 34 of the perimetric back wall 20 substantially bears
against the
inside face 29 of front base 24.
The expanded position of the suitcase gives rise to an expanded storage space
S', extending between inside face 19 of the back base 18 and an inside face 29
the front
base 24, with the perimetric side wall 30 fully expanded, wherein said
expanded storage
space S' has a thickens corresponding with the accumulated height of the
perimetric
back wall 20 with the height of the perimetric front wall 26 and the width of
the
perimetric side wall 30.
Collapsing the suitcase 10 from its expanded position into its collapsed
position,
takes place by detaching the one or more support boards 70 from the inside
face of the
perimetric side wall 30 and folding said support boards 70 inwards, in
direction of
arrows 79, deposing the support boards 70 against the inside face 19 of the
back wall
18. Then the perimetric side wall 30 can be folded inwardly into the space S'
and then
the two shells 12 and 14 are pressed against each other until the fully
collapsed position
is obtained, wherein the perimetric edge 34 of the perimetric back wall 20
substantially
bears against the inside face 29 of front base 24. Deploying the suitcase 10
into its fully
expanded position takes place in a reverse sequence, namely, first the two
shells 12 and
14 are displaced away from one another causing the perimetric side wall 30 to
fully
span and stretch out, whereupon the one or more support boards 70 are flipped
outwards
(in a direction opposite arrows 79), securing the support boards 70 to the
inside face of
the perimetric side wall 30, whereby the suitcase 10 is ready for use.
According to one particular example, the overall thickness of the suitcase, at
its
expanded position, can conform with the guidelines set by the International
Air
Transport Association (IATA) for cabin baggage/hand luggage/carry-on luggage
size,
defining a maximum thickness (depth) of 25 cm (10 inches), whereas at the
collapsed
position the thickness can be configured not to exceed about 6 cm. This,
however, is a
particular example and it is appreciated that the disclosure applies to any
size of
suitcase.
