Description
RELATED APPLICATIONS
[0001] This application is a .sctn.371 application from
PCT/FR2015/050199 filed Jan. 29, 2015, which claims priority from
French Patent Application No. 14 50947 filed Feb. 7, 2014, each of
which is incorporated herein by reference in its entirety.
FIELD OF THE INVENTION
[0002] This invention relates to luggage with a folding structure
that varies between a folded arrangement with a compact volume for
storage and an expanded arrangement of the usage volume.
[0003] The invention is particularly useful in its application to
the building of luggage with four wheels and a telescopic
handle.
BACKGROUND OF THE INVENTION
[0004] Currently, there is no known luggage system with a folding
structure that can satisfactorily vary the volume of luggage with
four wheels and a telescopic handle.
[0005] Wheeled luggage with a telescopic handle is generally made
up of a floor and lateral frames combined with a polypropylene
sheet shaped to form a C.
[0006] That design of the floor and the lateral frames makes it
possible to maintain the spacing, rigidity and co-planarity of the
four wheels, while allowing effective guidance with the telescopic
handle.
[0007] Document WO2013/028974 describes folding luggage comprising
a lower surface with a rigid front part and a rigid rear part. Said
rigid front and rear parts are connected so as to move from a
configuration that is substantially co-planar to one that is
substantially perpendicular. A locking mechanism is arranged to
lock said rigid front and rear parts in said substantially
co-planar configuration. The folding luggage comprises an upper
surface comprising a front part and a rear part. Said front part
and said rear part of the upper surface are arranged so as to move
from a substantially co-planar configuration to a substantially
perpendicular configuration. That folding luggage comprises a rear
surface, a left-hand lateral surface, a right-hand lateral surface
and a front surface. The luggage may be in an unfolded
configuration while in use, and in a folded configuration for
storage. In said unfolded configuration, said front and rear parts
of the bottom surface are locked in said substantially co-planar
configuration and said front and rear parts of the upper surface
are positioned in said substantially co-planar configuration. In
said folded configuration, said front and rear parts of the bottom
surface are placed in said substantially perpendicular
configuration, and said front and rear parts of the upper surface
are positioned in said substantially perpendicular
configuration.
[0008] The luggage locking mechanism described in document
WO2013/028974 is located at the middle of the lower surface, so
that the transmission of forces on the sides, that is to say
between the two front and rear left-hand wheels and the two front
and rear right-hand wheels are unbalanced.
[0009] The locking system presented there is not satisfactory, as
it does not allow adequate locking of the front and rear rigid
parts in relation to each other under heavy loads.
[0010] The locking system presented there is also not satisfactory
for withstanding a throwing test, because the rigid front and rear
parts do no remain co-planar.
[0011] Lastly, the locking system is not satisfactory while
rolling, because the rigid front and rear parts also do not remain
co-planar, as a result of which the transmission of force from top
to bottom of the product is imperfect, and rolling is
imperfect.
OBJECT AND SUMMARY OF THE INVENTION
[0012] A first aim of the invention is to propose new luggage with
a folding structure, the structure of which makes it applicable to
wheeled luggage and luggage without wheels.
[0013] A second objective of the invention is to propose new
luggage with a folding structure, where the structure is
lightweight and offers high rolling quality and stability
comparable to luggage with non-folding structure.
[0014] A third aim of the invention is to offer new luggage with a
folding structure where the selected volume can be maintained, even
while rolling.
[0015] The object of the invention is luggage with a folding
structure that can take a compact form for storage and an expanded
form of the usage volume, of the type with an access side and a
bottom opposite said access side, wherein said bottom is edged with
four lateral sides, characterized in combination by the fact that
one lateral side has a folding structure and is suitable for being
held rigidly using at least one lateral holding means.
[0016] Because the folding structure is suitable for being held
rigidly by lateral holding means, rolling stability and the
co-planarity of the wheels are achieved in an application of the
invention for building wheeled luggage.
[0017] According to other alternative characteristics of the
invention: [0018] at least one of the two lateral sides is
associated with at least one stiffening panel. [0019] at least one
stiffening panel is suitable for turning towards the bottom of the
luggage. [0020] the luggage with a folding structure has at least
one front wheel and at least one rear wheel mounted on the lateral
side with a folding structure and suitable for being held rigidly
by at least one lateral holding means. [0021] the lateral locking
means comprise a rigid means for joining at least one front wheel
and at least one rear wheel mounted on the lateral side with a
folding structure and suitable for being held rigidly by at least
one lateral holding means. [0022] the lateral side with a folding
structure that is suitable for being held rigidly by at least one
lateral holding means makes up a floor with two rigid parts joined
to each other by a hinge, wherein each of them bears at least one
front wheel and at least one rear wheel. [0023] the lateral side
that makes up the floor has two rigid parts and at least one
joining rod that makes it possible to stiffen the folding floor.
[0024] each joining rod that stiffens the folding floor joins the
wheel casings to create a rigid link between the two wheels and to
keep them co-planar. [0025] at least one joining rod rotates around
a fixed point located close to one of the wheels between two main
positions: a first folded position that does not join the wheels
and an unfolded position that creates the link with another wheel.
[0026] each joining rod may be mounted inside the folding suitcase.
[0027] the assembly for the fastening, movement and holding of a
joining rod can be mounted directly inside the suitcase on an
interior wheel casing. [0028] at least one stiffening panel
suitable for turning towards the bottom of the luggage can be
articulated at the bottom of the luggage.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0034] By reference to FIGS. 1 to 4, identical or functionally
equivalent elements are given identical reference numbers.
[0035] The structure of the luggage with a folding structure
according to the invention described by reference to FIGS. 1 to 4
is particularly advantageous for the construction of luggage with
four wheels, so as to ensure smooth rolling in all the arrangements
corresponding to a given volume, while retaining the properties of
resistance to impacts, the use and the carrying of the wheeled
luggage with a non-folding structure according to the prior
art.
[0036] The invention makes it possible to vary the volume of
wheeled luggage in a simple and ergonomic manner, with no
disassembly or particular manipulation, to fold the floor for
storage and provide a rigid and continuous floor for rolling. That
volume variation makes it possible to reduce the thickness of the
luggage for the purpose of storage when it is not in use.
[0037] In usage mode, the folding floor does not collapse under the
weight of the load, particularly at the folding line: the invention
thus makes it possible to assemble a system with four wheels on the
floor and ensure perfect rolling in the four-wheeled mode.
[0038] In FIG. 1, luggage with a folding structure according to the
invention is luggage with wheels R and a telescopic handle T
comprising a bottom 1, a floor 2 and a top 3.
[0039] Two lateral sides 4 extend from the bottom 1, between the
floor 2 and the top 3
[0040] An access side 5 with a zip fastener is opposite the bottom
1 and edges the lateral sides 4, the floor 2 and the top 3.
[0041] The floor 2 is a floor that folds between an arrangement
with a compact volume for storing the luggage represented in FIG. 1
and an arrangement with a large volume represented in FIG. 2.
[0042] The floor 2 comprises two parts: a rigid front part 2a and a
rigid rear part 2b articulated by a hinge 2c.
[0043] The hinge 2c may be made by stitching textile enclosures
made integral with the rigid parts 2a and 2b of the floor 2, so
that the front part can rotate towards the inside of the
product.
[0044] The rigid parts 2a and 2b of the floor 2 are folded
substantially at right angles in the arrangement with a compact
storage volume, to reduce the thickness of the floor 2.
[0045] The rigid parts 2a and 2b of the floor 2 each have two
wheels R placed laterally in the vicinity of the lateral sides
4.
[0046] The front part 2a of the floor 2 is thus a rigid part, which
carries two casings 6 that support the wheels R.
[0047] The rear part 2b of the floor 2 is also a rigid part, which
carries two other casings 6 that support the wheels R.
[0048] The top 3 of the luggage with wheels R and a telescopic
handle T is generally made of a polypropylene sheet with a C-shaped
arrangement that extends the bottom 1 and makes up a return. The
top 3 has an opening that makes it possible to mount the telescopic
handle T.
[0049] The invention also extends to an unrepresented alternative
of luggage with a top 3 that can be folded between an arrangement
with a compact volume for storing the luggage represented in FIG. 1
and an arrangement with a large volume represented in FIG. 2. The
top 3 of this unrepresented alternative luggage with a folding
structure according to the invention may to that end comprise a
front part and a rear part that can be folded substantially at
right angles in the arrangement with the compact volume for
storage. The front and rear parts of the top 3 may be complementary
near the lateral sides 4, to make up a substantially rigid top
3.
[0050] The lateral sides 4 extend from the bottom 1, between the
floor 2 and the top 3, and are associated with stiffening panels 4a
suitable for turning towards the bottom of the luggage.
[0051] Those rigid pivoting panels 4a are mounted inside the
structure of the luggage with a folding structure, to make up
stiffening frames in the arrangement with a large volume
represented in FIG. 2.
[0052] The stiffening panels 4a are fixed to the rear or bottom 1
of the luggage with a folding structure and are not fixed on their
other sides, in order to be able to rotate so as to be folded
inside the structure of the luggage with a folding structure.
[0053] These stiffening panels 4a thus turn inside the structure of
the luggage with a folding structure, in the arrangement with a
compact volume for storing the luggage represented in FIG. 1.
[0054] The pair of rigid turning panels 4a are thus folded on top
of each other in the arrangement with the compact volume for
storing the luggage 1 represented in FIG. 1.
[0055] The stiffening panels 4a are made by means of a textile
enclosure and are preferably edged by continuous rigid frames that
hold them and keep them from being deformed inside the luggage with
a folding structure.
[0056] The invention described by reference to luggage with a
folding structure and four wheels R and a telescopic handle T also
extends to suitcases with two wheels, with or without lateral
frames, and luggage with soft folding structures such as duffel
bags. The stiffening panels 4a may comprise elements other than
lateral frames, such as glass fiber rods, which may or may not be
removable.
[0057] In FIG. 2, the luggage with a folding structure 1 according
to the invention is represented in its arrangement with a large
usage volume.
[0058] In that arrangement with a large usage volume, the front
part 2a is co-planar with the rear part 2b of the floor 2.
[0059] The front part 2a and rear part 2b are joined by the
articulation 2c.
[0060] Lateral locking means 2d are mounted alternatively on the
front part 2a or the rear part 2b, near the casings 6 that support
the wheels R.
[0061] The locations of the lateral locking means 2d are preferably
made in the internal parts 6a of the support casings 6 of wheels
R.
[0062] The lateral locking means 2d may be made of any rigid
material, such as glass fiber, steel or rigid plastic.
[0063] The spacing between the lateral locking means 2d of the
front part 2a and the rear part 2b of the floor 2 avoids the
concentration of stresses in the middle of floor 2. Thus, that
avoids building up diverted flexion at the middle of the floor 2
and deforming the rolling plane at the locations of the support
housings 6 of the wheels R, as the forces are distributed over a
greater width, corresponding to the interior edges of the floor
2.
[0064] In the arrangement with the large usage volume, the front of
each stiffening panel 4a is fixed and held at a front edge of the
lateral side 4 by a Velcro (registered trademark) tape or press
studs.
[0065] The rear of each stiffening panel 4a is fixed and held at
the rear of each lateral side 4 by a hinge 4c, which may be made by
stitching a textile enclosure made integral at the rear of each
lateral side 4.
[0066] In the movement towards the arrangement with a large volume,
each stiffening panel 4a is guided by the hinge 4c made integral at
the rear of each lateral side 4. The rigid turning panels 4a thus
open outward and are articulated on the rear side of the luggage,
so that the rigid turning panels 4a take up positions that are
substantially parallel in the arrangement with a large volume.
[0067] Because at least one of the two lateral sides is associated
with at least one stiffening panel that is adapted to turn towards
the bottom of the folding luggage, the force is transmitted evenly
from the top of the luggage to the bottom and rolling is
improved.
[0068] Thus, thanks to the invention, the luggage with a folding
structure has a stable and rigid structure in the arrangement with
a large volume: the lateral parts 4 are stabilized by rigid turning
panels 4a in the arrangement with a large volume.
[0069] In FIG. 3, a locking means for luggage with a folding
structure according to the invention in the folded arrangement with
a compact volume for storage is represented.
[0070] The front part 2a and rear part 2b are joined by the
articulation 2c.
[0071] Lateral locking means 2d are mounted in this example on the
rear part 2b, near the support casings 6 of the wheels R.
[0072] The locations of the lateral locking means 2d are made and
directly incorporated into the internal parts 6a of the support
casings 6 of wheels R.
[0073] The lateral locking means 2d comprise elongated elements 7
in rigid material, such as glass fiber, steel or rigid plastic.
[0074] The elongated elements 7 in rigid material are mounted to
rotate between a free position that is substantially parallel to
the bottom 1 and a forced position that is substantially
perpendicular to the bottom 1.
[0075] In the free position substantially parallel to the bottom 1,
the elongated elements 7 in rigid material do not exceed the
articulation line 2c.
[0076] If there are several elongated elements 7 in rigid material,
the elongated elements 7 in rigid material may be articulated on
the front or the rear of the floor 2 of luggage with a folding
structure according to the invention.
[0077] When the elongated elements 7 in rigid material are
articulated on the rear as shown, the rigid turning panels 4a have
downward-turned indents to allow them to pass above the internal
parts 6a of the support casings 6 of the wheel R of the luggage
with a folding structure.
[0078] When the elongated elements 7 of the rigid material are
articulated at the front of the luggage with a folding structure,
near the access opening 6, the rigid turning panels 4a may not have
backward-turned indents.
[0079] In FIG. 4, each elongated element 7 in rigid material is
locked in two housings 8a, 8b, so as to thus make up a rigid
co-planar holding link for the front part 2a and rear part 2b
joined by the articulation 2c.
[0080] The locations of the housings 8a, 8b are preferably located
on the internal parts 6a of the support casings 6 of wheels R.
[0081] That co-planar rigid holding link thus allows the smooth
rolling of the luggage with a folding structure, four wheels R and
a telescopic handle T.
[0082] Each elongated element 7 in rigid material is embedded in
the housings 8a, 8b integral with the front half floor 2a and rear
half floor 2b, so that no force is applied on the axis of rotation
of the elongated element 7 in rigid material.
[0083] The invention also covers the unrepresented alternative in
which at least one elongated element 7 in rigid material is mounted
to rotate between a free position that is substantially parallel to
the bottom 1 and a forced position that is substantially
perpendicular to the bottom 1 in the front half floor 2a.
[0084] The invention also covers the unrepresented alternative
comprising only one elongated element 7 in rigid material that is
mounted to rotate between a free position that is substantially
parallel to the bottom 1 and a forced position that is
substantially perpendicular to the bottom 1.
[0085] The invention also covers the unrepresented alternative
comprising more than two elongated elements 7 in a rigid material
mounted differently, to make up a rigid holding link that is
co-planar with the front part 2a and rear part 2b of the floor
2.
[0086] The essential feature is that the invention provides a
lateral rigid linking means between a front wheel R and a rear
wheel R on the same side. That rigid link is provided by the two
rods 7 that link the interior wheel casings 6a and stiffen the
folding floor 2. In the unfolded position, the invention makes it
possible to link the front wheel R with the corresponding rear
wheel R, in order to create a rigid link between the two wheels R
and make them co-planar.
[0087] The invention simply provides for two rods or rigid links 7
which link, in the unfolded position, directly and rigidly a zone
near the front wheel R to a zone near the corresponding rear wheel
R.
[0088] Thus, at least one rod 7 rotates around a fixed point
located close to one of the wheels R, and can thus occupy two main
positions: one folded position that does not link the wheel casings
and is parallel to the bottom 1 of the suitcase, and an unfolded
position that creates a link with another wheel on the other half
floor and is perpendicular to the bottom 1 of the suitcase.
[0089] The invention thus makes it possible, in the unfolded
position, to ensure the perfect transmission of force between the
front and rear of the luggage, and hold the front and rear wheels
on the same plane, to allow perfect rolling in the four-wheel
mode.
[0090] In the preferred embodiment of the invention, the rod system
7 is placed inside the folding suitcase, and the system for
fastening, rotating and holding the rods 7 is integrated directly
on the interior wheel casings 6a inside the suitcase.
[0091] A first housing 6a for the wheel R, for example the rear
housing at the back of the suitcase, bears the rod 7 mounted around
an axis of rotation.
[0092] An additional housing 8a that catches the rod 7 in the
unfolded position is provided to prevent the transmission of forces
to the point of fastening and the axis of rotation of the rod
7.
[0093] A second housing 6a for the wheel R, for example the front
housing of the suitcase, bears a housing 8b that holds and locks
the rod 7 on the other half floor in the unfolded position.
[0094] The invention also covers the unrepresented alternative in
which at least one elongated element 7 in rigid material is
integrated into an exterior housing 6b of the wheel R.
[0095] The invention also covers the unrepresented alternative in
which at least one elongated element 7 in rigid material, which is
not directly integrated in an interior or exterior wheel casing, is
mounted nearby, directly or by means of an added part, particularly
in the case of manufacturing by injection in several pieces.
[0096] In order to implement the invention, the user starts by
unfolding the floor 2, then fastens the rods 7 to the casings 6a.
Lastly, the user makes the rigid turning panels 4a rotate from the
inside to the outside and the front of the luggage with a folding
structure.
[0097] During that movement of rotation, the bottom of the rigid
turning panels 4a could hit or be blocked by the wheel casings 6a,
on the surfaces of housings 8a, 8b, protruding from the floor
2.
[0098] If the presence of the housings 8a, 8b that hold the rod 7
on the interior casings 6a raises volume problems during
manipulation, rigid turning panels 4a that are slightly shorter
than the internal height of the suitcase are provided.
[0099] The bottom parts of the rigid turning panels 4a do not touch
the bottom of the product and are indented so as to pass above the
housings 8a, 8b of the interior casings 6a of the wheels R during
rotation
[0100] In that case, each interior casing 6a of a wheel R comprises
a raised edge 9, which is set against the rigid frame of the
turning panel 4a. That edge 9 does not merely hold a rigid frame of
a mobile turning frame 4a correctly, but it also makes up for the
shorter height of the rigid frame of the turning panel 4a and
supports it at the proper height.
[0101] In order to reinforce the rigidity and stability of the
luggage with a folding structure according to the invention in all
the arrangements corresponding to a selected volume, it is
advantageous to provide additional means for locking the rigid
frames of the turning panels 4a for stiffening, so as to hold the
stiffening frames in position in their arrangement for the
transmission of vertical and lateral forces.
[0102] The invention described by reference to several particular
embodiments is not limited in any way to those embodiments, but
covers all modifications of shape and all alternative embodiments
as part of the attached claims.
[0103] Thus, the luggage according to the invention may comprise at
least one stiffening panel (4a) that is mobile in another manner,
for example at least one stiffening panel (4a) that is suitable for
pivoting to the front or towards the access side of the
luggage.
[0104] Thus, the luggage according to the invention may comprise at
least one lateral holding means (2d) that may be articulated in
another manner, for example at least one folding means such as a
second floor, the axis of articulation of which is transversal to
the axis of the hinge of the lateral side (2) with a folding
structure that makes up a floor (2) with two rigid parts (2a, 2b)
joined to each other by a hinge.
