Definitions

  • the invention relates to a suitcase comprising a reduced volume folding device, the invention is more particularly, but not exclusively, intended for a flexible or semi-rigid suitcase, provided with 4 wheels for its movement by rolling in vertical position.
  • the ability to fold the bag that is to say significantly reduce its thickness, when it is not used, facilitates the storage of said bag, for example under a cabinet or on a shelf.
  • the driving comfort is largely related to the rigidity of the floor supporting the wheels and taking up most of the weight of the load when the suitcase is upright.
  • the floor must be rigid and ensure the coplanar maintenance of the 4 wheels, it must also be mechanically coupled with the operating handle and ensure the transmission of maneuvering forces to the wheels and loading.
  • the floor is generally the widest element, so that to fold the bag and thus obtain a configuration of reduced thickness for storage, the width of the floor must be reduced in the meaning of the thickness of the bag.
  • the suitcase object of the invention incorporates basic characteristics by improving them
  • the bag targeted by the invention comprises a front face (110) allowing access to the content of the bag, a bottom (120) substantially parallel to the front face, the distance between the bottom and the front face defining the thickness of the bag.
  • the width of the bag is delimited by its side faces (130) and the bag extends vertically between a floor (150) and a ceiling (140).
  • the case has a maneuvering handle (160), preferably telescopic, comprising tubular uprights (161, 162) extending along the bottom (120) and connected to the floor (150).
  • the bag comprises 4 wheels (170) mounted on pivoting bearings along a vertical axis, and which are fixed to the floor (150) of the bag, for rolling in the vertical position.
  • the document US 2015/0327640 describes an example of such a foldable suitcase.
  • the folding is obtained by means of a hinge present in the floor along an axis (151) parallel to the width of the bag.
  • the floor is thus made of two parts, articulated together by this hinge.
  • pivoting reinforcing bars extending between the roller bearings, are installed inside the bag, which bars must be maneuvered during each folding and unfolding .
  • the folding system impacts the empty weight of the bag.
  • WO 2008/100117 describes a foldable suitcase in which is fixed on each textile side wall, and the floor and ceiling stiffening elements comprising at their ends housing for 4 connecting jumpers.
  • Each jumper once installed provides the connection between a side wall and the bottom or ceiling.
  • the walls can be folded towards the bottom as well as the ceiling and the floor.
  • This system of the prior art has the disadvantage of having to handle the link jumpers, at the risk of losing one, and in this case a suitcase can no longer be used.
  • telescopic handle is linked to the rigid bottom of this bag of the prior art and is not directly linked to the floor supporting the wheels, so that such a bag is difficult to maneuver.
  • the invention aims to solve these disadvantages and concerns for this purpose a foldable bag between a configuration of use and rolling and a storage position of reduced thickness, comprising a bottom and an access face to the contents of the bag on its opposite side to the bottom, the bag extending in width between side walls, in thickness between the bottom and the access surface to the contents and vertically between a ceiling and a floor, rolling elements being fixed to said floor, a a floor-and-floor-related operating handle extending along the bottom, wherein the floor comprises a one-piece support structure extending in the width and thickness of the case and wherein the connection between the operating handle and the floor is a pivot connection axis parallel to the width of the bag, comprising indexing the operating handle in the use position and rolling.
  • the folding of the bag is obtained by folding the floor to the operating handle, that is to say towards the bottom, after deindexing, by means of the pivot connection.
  • This operation has the effect of bringing the floor closer to the bottom by bringing them in a substantially parallel configuration to one another.
  • the thickness of the bag is reduced in storage configuration, while maintaining a rigid floor and a single piece, ensuring the rolling comfort of the case in use configuration.
  • the suitcase object of the invention comprises pivoting stiffening panels to stiffen the side walls, said panels extending parallel to the side walls when the bag is in use configuration and rolling, and comprises a device cooperating with the support structure (255) of the floor for holding the pivoting panels in position in this configuration.
  • the stiffening panels maintain the contents of the case substantially aligned with the floor during maneuvers, also promoting the transmission of driving torque in rolling, and improve the comfort of use and maneuverability of the bag in this position.
  • the support structure of the floor is a ribbed perforated structure made of a molded plastic material.
  • the floor is light and rigid, ensuring the coplanar positioning of the wheels.
  • Obtaining the support structure by molding makes it possible to integrate numerous functions into this one-piece structure.
  • the operating handle comprises vertical uprights, said uprights being connected to the floor by sleeves, said sleeves being connected to the support structure of the floor by a pivot connection.
  • the same support structure is adaptable to a set of suitcases, the sections or the heights of the amounts are different.
