Definitions

  • the present invention relates to a frame construction for a piece of luggage, preferably for a suitcase shell, according to claim 1 for fastening a liner to the piece of luggage, to a liner for such a frame construction, and to a method for attaching a liner to a suitcase shell by means of such a frame.
  • liners can also be used for partitioning the interior of a piece of luggage in order to separately house different objects.
  • Many ways of securing or attaching liners to a piece of luggage are known.
  • the liners can be adhesively secured or sewn to the piece of luggage.
  • Such a permanent fixation can be advantageous due to the durability of fixation.
  • Another possibility of securing a liner to a piece of luggage is to provide a connection such as a frame to which the liner can be attached and detached easily.
  • EP 2 672 857 teaches to fasten a liner to a stiffening frame of a suitcase shell by means of a T-shaped sliding element that is, with its one edge region, inserted into the stiffening frame and, with its other edge region, attached to the liner. Whereas this type of connection allows the replacing of the liner its mounting is however complicated. In fact, the liner has to be slided in the groove in a rather laborious and labor intensive manner.
  • a frame construction for a piece of luggage preferably for a suitcase shell, comprises a frame, said frame comprising a profile with a profile base and a first profile wall and a second profile wall.
  • a seat for a liner is delimited by opposing first and second inner surfaces of said first and second profile walls, respectively, that face one another.
  • the said first inner surface is provided with a first groove and said second inner surface is provided with a second groove, said first and second grooves facing one another and extending in a longitudinal direction of said profile.
  • the said frame construction further comprises a strip for being inserted into said profile with opposing lateral edge regions in said first and second grooves for fastening said liner being inserted into said seat.
  • the frame construction comprises a frame with a profile having a profiled groove or profile slot, into which a liner can be inserted.
  • Said liner is then secured within the profile by means of the strip.
  • the strip secures the liner within the profile and thus prevents an unintentional removal of the liner.
  • the liner is thereby also removably fastened to the frame construction and as a result easily exchangeable.
  • Said profile can be designed so as to be essentially U-shaped, i.e. with profile walls extending essentially perpendicularly with respect to the profile base. Other designs are however conceivable, too.
  • said profile could likewise be essentially C-shaped, i.e. with essentially curved profile walls.
  • the said first and second grooves can be arranged to be on the same height with respect to a depth of the profile.
  • the first and second grooves can be provided in the respective profile walls at equal distances from the profile base.
  • the strip inserted into the grooves extends parallel to the profile base.
  • the strip preferably extends, when inserted into said first and second grooves, along said longitudinal direction of said frame around substantially the entire frame.
  • the profile extends along the longitudinal direction of the frame and around substantially the entire frame. In this way it is possible to attach the liner to the frame along the entire circumference of the frame, such that the suitcase shell can be completely lined.
  • the strip, and thus also the profile extends only partially and/or in sections along the longitudinal direction of the frame. In this way, it is possible to only partially line the suitcase shell.
  • Said first and second profile walls can extend parallel to one another or can diverge from one another towards their free edge regions or can converge towards one another in the direction of the profile base.
  • Divergent profile walls as well as convergent profile walls are arranged inclined or tilted with respect to one another and with respect to the profile base, respectively.
  • An inclination in the case of divergent profile walls has the advantage that the insertion of the strip is facilitated.
  • An inclination in the case of convergent profile walls has the advantage that the seat has larger dimensions such that the liner is easier accommodated within the seat, while at the same time the profile walls in the region of their free edge regions reduce the insertion opening of the profile such that the liner is held better within the seat.
  • Divergent profile walls preferably include in each case an angle of inclination with respect to the profile base of larger than 90°, preferably between about 92° to 120°, particularly preferably between about 95° to 100°.
  • Convergent profile walls preferably include in each case an angle of inclination with respect to the profile base of smaller than 90°, preferably between about 60° to 88°, particularly preferably between about 80° to 85°.
  • the first and second profile walls can be, in a cross-sectional view of the profile, straight, and/or the first and second profile walls can have the same heights.
  • Straight profile walls are arranged perpendicularly with respect to the profile base and profile walls having the same heights extend from the profile base by the same amount. It is however also conceivable that the profile walls have different heights, i.e. that one of the profile walls extends from the profile base by a lesser amount than the other profile wall.
  • Said first and second grooves and said strip are preferably dimensioned such that, when said strip is inserted into said first and second grooves, a gap is formed between the strip and the first and second inner surfaces, the gap being provided for guiding said liner from within the profile around said strip to an outside of the profile.
  • the gap allows the liner to extend from within the seat of the profile laterally around the lateral edge regions of the strip to the outside of the profile. In this way it is possible to guide the connected liner into the interior of a suitcase.
  • the strip preferably has a height that is slightly smaller than the diameter of the grooves and a width that is slightly smaller than the distance of the first and second profile walls from one another.
  • Such an arrangement especially if the first and second grooves are arranged on the same height with respect to the depth of the profile, has the advantage that in case a pulling force is exerted on one side of the liner the other side of the liner is thereby caused to move along the direction of the pulling force. Thereby, said other side of the liner pushes its associate lateral edge region of the strip against the groove in the profile wall. As a result, the strip and the liner are further clamped in the profile and hence a self-locking provided.
  • the frame can be a single piece element, preferably made from aluminium or plastics. However, it is also possible to form the frame in two or multiple parts, wherein said parts are connected with each other by means of appropriate connecting means such as adhesives or fastening means such as screws or profile pieces.
  • the frame is made of a material giving it stiffness, for example if it is made from aluminium, the frame constitutes a so-called stiffening frame.
  • Such a stiffening frame has an increased stiffness and therefore also an increased stability over a frame manufactured from plastics, for example.
  • the frame construction would likewise correspond to a stiffening frame construction.
  • the frame construction is preferably configured such that, when said liner is inserted into said seat, said strip may be clicked or snapped into said profile from a direction transverse to said longitudinal direction of said profile whilst said liner is pressed into said first and second grooves. It is also preferred that the frame construction is configured such that, when said liner is inserted into said seat, said strip may be slid into said profile along said longitudinal direction of said profile whilst said liner is pressed into said first and second grooves. In order to simplify the insertion of the strip into the grooves of the profile, especially in the case of fastening the strip by clicking or snapping, it is advantageous to form the strip slightly narrower than the distance between the first and second profile walls.
  • the frame construction preferably comprises a further frame, wherein the frame comprises a connection profile and the further frame comprises a further connection profile being designed complementary to the connection profile of the frame, the connection profile and the further connection profile being configured to enter into a preferably positive connection with one another.
  • the frame construction can comprise two frames which preferably in each case comprise a profile as described above. However, it is also conceivable that only one of the frames comprises a profile as described above. It is also preferred that the frames are connectable to one another by means of their complementary connection profiles.
  • the suitcase shells are preferably connected with each other by one or more articulated joints such as hinges.
  • a liner for use with a frame construction as described above comprises at least one region of increased thickness to be inserted into said seat, wherein said region of increased thickness preferably corresponds to at least one fold, and wherein one or more elongated members are preferably arranged at or in said fold, said elongated members being preferably tubes, wires or strings.
  • Said elongated members are preferably fixedly fastened to said liner, preferably by means of stitching, weaving, and/or adhesive.
  • said liner is a single-piece element or is made from different layer materials.
  • said elongated member is dimensioned such that, when inserted, together with said liner, into said seat, the elongated member exerts a self-locking force onto the profile so as to remain in place while said strip is inserted. Hence, it thereby assists the positioning of the liner.
  • the liner preferably corresponds to a fabric or textile which has at least one fold or kink that is inserted into the seat of the profile.
  • the liner can be provided as a single-piece element, e.g. in the form of a textile or fabric formed in one piece and having homogeneous properties throughout the whole liner.
  • a liner being made of a smooth and/or thin fabric which allows for an easy removal of the strip and replacement of the liner.
  • the liner could also be provided as a multi-piece element, e.g. in the form of two or more textile or fabric pieces that are connected such as sewed or glued together. Said two or more textile or fabric pieces can again have the same or different properties. That is, the liner could consist of two textile pieces, one textile piece being thicker or courser or having a different mechanical property than the other textile piece.
  • the liner could comprise a first textile piece forming a first liner area made of a rigid or inelastic material and a second textile piece forming a second liner area made of a soft or elastic material.
  • the inelastic material can be made to extend along the inner surface of the suitcase shell and the elastic material can be made to extend across the interior of the suitcase shell and serve the purpose of a divider or partition that divides the interior space of the suitcase into a first and a second space.
  • both liner materials are made to extend along the inner surface of or across the suitcase shell.
  • the liner comprises a thicker or coarser liner area only in the region of the profile, particularly in the regions of the grooves. In doing so, an area of increased friction is provided in the region of connection between the strip and the profile only, while the remaining parts of the liner can continue to be, e.g. smooth or elastic.
  • the liner can be provided as a single layer material comprising one layer of a single-piece or multi-piece fabric.
  • the liner can be provided as a multi-layer material comprising two or more single-piece and/or multi-piece fabrics.
  • elongate members can be provided in the form of a tube, string or a wire which, together with the liner, extend along substantially the entire profile and thus the frame.
  • a piece of luggage preferably a suitcase, or a suitcase shell, with a frame construction as described above comprising said liner.
  • Said liner extends into said seat and said strip is secured in said first and second grooves whilst the strip presses said liner into said first and/or second groove(s).
  • the liner can comprise at least one fold, said fold being inserted into said seat.
  • One or more elongated members can be inserted into said at least one fold, said elongated members being preferably wires or strings.

  • the fastening element 42' comprises a further retaining structure 415' in the form of a further protrusion, which, when the end portion 101' of the shell 100' is received in the seat 41', presses against the surface 102' of the shell 100' facing said further retaining structure 415', such that an additional fastening of the end portion 101' being received in the seat 41' is effected.
  • the fastening element 42' has an elongate shape with an upper side 418' and a lower side 419', wherein the retaining structures 413', 415' are arranged opposite one another and in each case extend along an entire width WF of the fastening element 42'.
  • the fastening element 412' essentially takes the form of an "L". Furthermore, the fastening element 42' extends, when inserted in the seat 41' of the shell profile 4', partially along the extension direction E of the shell profile. In fact, the fastening element 42' has a width WF that is a small fraction of the extension lengths of the first and second profile walls 44', 45' along the extension direction E. It is therefore conceivable to provide two or more, in particular a plurality of such fastening elements 42' which can be distributed along said extension direction E around substantially the entire frame 1.
  • the fastening element 42' is dimensioned such, that a gap 417' is formed between the profile base 43' and the lower side 418' of the fastening element 42' and that the upper side 419' of the fastening element 42' is essentially flush with the free end 411' of the second profile wall 45' when the fastening element 42' is inserted in the seat 41' of the frame 1'.
  • the free end region 48' of the first profile wall 44' has a retaining structure 416' in the form of a lug extending inwards in the direction of the seat 41', wherein said retaining structure 416', when the end portion 101' of the shell 100' is received in the seat 41', presses against the surface 103' of the shell 100' facing said retaining structure 416' such that an additional fastening of the end portion 101' being received in the seat 41' is effected.
  • the first and second profile walls 44', 45' extend essentially parallel to one another, wherein the second profile wall 45' has a length LP2 which is greater than the length LP1 of the first profile wall 44' along the transverse direction TE.
  • the shell profile 4 has essentially the shape of a "U", wherein the first and second profile walls 44', 45' correspond to the side legs of said "U”, and wherein the side leg associated with the second profile wall 45' is longer than the side leg associated with the first profile wall 44'.
  • the region of the second profile wall 45' that is extended with respect to the first profile wall 44' is arranged offset with respect to the remaining part of said second profile wall 45'.
  • a groove 420' is formed, within which groove 420' the retaining structure 413' of the fastening element 42' can be received.
  • the shell 100' in turn has a curvature 104' dividing the shell 100' into the end portion 101' and a main portion 105', whereby the main portion 105' is arranged off-set with respect to the end portion 101', and wherein the length LP2 of the second profile wall 45' essentially equals the overall length of the end portion 101' and the curvature 104' in the transverse direction TE.
  • the second retaining structure 415' of the fastening element 42' presses against the first surface 102' of the shell 100' in the region of the curvature 104'.
  • the curvature 104' in particular its inclination and its longitudinal extension, is selected in this case such, that the main portion 105' is laterally offset with respect to the end portion 101' of the shell 100' and essentially flush with the first profile wall 44'. In other words, the main portion 105' of the shell 100' and the first profile wall 44' essentially extend in a common plane.
  • the frame construction as described above is not restricted to the suitcase shown in the present figures. Instead, it is conceivable to provide such a frame construction to other types of suitcases, e.g. suitcases without wheels, and in particular to any type of luggage comprising two shells to be interconnected.
