Definitions

  • the present disclosure relates generally to a wheeled luggage article and particularly to a luggage article with a foldable base assembly.
  • Luggage articles and in particular luggage cases conventionally include base assemblies having mounted wheel brackets and wheels to allow the case to be pulled or pushed along with the user.
  • luggage cases may be foldable in order to reduce the volume of the case for storage when not in use.
  • the luggage may be foldable between an orientation for storage and an orientation for use. It is effectively known to use fixed wheel assemblies (non-caster or spinning wheel assemblies) in foldable luggage.
  • caster or spinning-type wheel assemblies are popular for the additional directional control they allow when guiding luggage across a support surface.
  • the design of such luggage presents a particular unique challenge. Specifically, the luggage must be sufficiently robust to withstand use under heavy loading of the case and transport over rough surface. The luggage must also provide sufficient rigidity to reduce or mitigate deflection of the case in the various dimensions. On the other hand, the internal structure of the luggage must also be compact so as to emphasize the weight and volume that the case can carry for a given overall size and weight while simultaneously allowing a small storage volume of the case when folded. Further, a caster or spinning-type wheel assembly is more complicated and structurally challenging to integrate into a luggage case than a simple upright "fixed" wheel assembly. The luggage must also be simple and easy to handle.
  • Documents that may be related to the present disclosure in that they include various foldable wheel brackets include CN201718657 , EP0584135 , EP1718183 , EP2536613 , EP2779860 , US2008135365 , US2010282556 , US2011083933 , US2011162931 , US6478315 , US6604617 , US7246805 , US7849984 , and US8413775 .
  • the present disclosure advantageously provides a foldable yet stable base assembly for a luggage article.
  • the base assembly may have sufficient strength to maintain the luggage article upright when in use.
  • the base assembly may include a foldable portion and a fixed portion, the foldable portion pivotally connected to the fixed portion so the luggage article may be sufficiently collapsed through resilient folding of the luggage article.

As explained below, the luggage article 100 may be formed from a variety of materials and means to allow the luggage article 100 to be resiliently deformable between open and folded positions.
  • the luggage article 100 may be split along an opening line 120 into a lid section 122, which includes the front wall 102, and a base section 124, which includes the rear wall 104.
  • the lid section 122 may be pivotally connected to the base section 124 along a portion of the luggage article 100 via a hinge 126, such as a fabric strip, a piano hinge, discrete hinges spaced apart, or an articulating joint.
  • a closure mechanism such as a zipper 128, may extend along the opening line 120 to releasably secure the lid section 122 to the base section 124.
  • the zipper 128 may be unzipped to allow the lid and base sections 122, 124 to pivot about the hinge 126 to allow access to the interior. While described hereafter as a zipper 128 and a hinge 126, respectively, various types of closure mechanisms and hinge structures are acceptable.

  • the recess 177 and the blocking member 180 may be reversed to move the blocking member 180 into and out of engagement with the recess 177.
  • the force of the spring may be overcome when a user biases the actuator portion 178 to withdraw the blocking member 180 from the recess 177 and disengage the detent 174.
  • the blocking member 180 engages the sliding member 176 of the detent 174 to lock the foldable portion 135 in an open position. As shown in Fig.
  • the blocking member 180 includes a first angled surface 187 that corresponds with and slidably bears against a second angled surface 189 of the lower tab 175A to move the sliding member 176 in a direction opposite the spring biasing direction when the foldable portion 135 is rotated towards the lower arm 142.
  • the angled surfaces 187, 189 create a cam force on the sliding member 176 to auto-align the blocking member 180 and the recess 177 to "click" into engagement.
  • Other locking mechanisms may also be used on or in connection with the base assembly 134 in some examples.
  • the foldable portion 135 in an open position, may extend substantially perpendicular to the fixed portion 137 (e.g., the upper arm 140). As shown, the bottom surface 181 of the foldable portion 135 sits substantially flush with a bottom surface 183 of the fixed portion 137. In some embodiments, a rear end 184 of the foldable portion 135 may abut a forward end 186 of the fixed portion 137 when the foldable portion 135 is in an open position. Furthermore, the foldable portion 135 may be positioned to extend substantially linearly relative to the lower arm 142 of the rear wheel bracket 136A. To further define an open position, the foldable portion 135 and the fixed portion 137 may include corresponding limit surfaces or structures 188 that engage each other to limit the rotation of the foldable portion 135 relative to the fixed portion 137 in at least one direction.
  • the foldable portion 135 may engage a portion of the luggage article 100 (e.g., the upper arm 140 of each rear wheel bracket 136A).

  • the foldable portion 135 may extend substantially parallel to the fixed portion 137 (e.g., the upper arm 140).
  • Other mechanisms may also be used in connection with the foldable portion 135 in some examples to define a folded position of the base assembly 134.
  • a portion of the foldable portion 135 may engage a corresponding portion of the fixed portion 137 to limit the rotation of the foldable portion 135 towards the upper arm 140.
  • the foldable portion 135 of the base assembly 134 may include a base 146 extending at least partially across the bottom end wall 112 towards the front wall 102 of the luggage article 100.
  • the base 146 which may be a panel or an arm, may be one of many components of the bottom end wall 112.
  • an outer surface (e.g., an exterior surface or an interior surface) of the base 146 may be attached to the hard side and/or the soft side outer material of the luggage article 100.
  • the base 146 which may be constructed of polypropylene board, honeycomb panel, or other material or structure suitable to reduce the overall weight of the luggage article 100 and increase the structural rigidity of the base 146, may include a proximal end or edge 148 and a distal end or edge 150.
  • the proximal end or edge 148 may be connected to the foldable portion 135, and the distal end or edge 150 may be connected to the housing or luggage structure to form the lower front edge 118 of the luggage article 100.
  • the base 146 and bottom end wall 112 may move with the foldable portion 135 as the foldable portion 135 pivots at the first pivot axis P.
  • the base 146 extends substantially parallel to the foldable portion 135.
  • each front wheel bracket 136B may be connected to the distal end or edge 150 of the base 146.
  • a gap G may be defined adjacent the lower rear edge 116 of the luggage article 100 and between the base 146 and the rear panel member 156 to allow the base assembly 134 to move between open and folded positions. As explained below, when moving from an open position to a closed position, the gap G may decrease in size to permit the base 146 to be positioned nearer the rear panel member 156 when the base assembly 134 is in a folded position.
  • the base assembly 134 may be moved between open and folded positions to open and collapse the luggage article 100.
  • the base 146 in an open position, may extend substantially perpendicular to the rear wall 104 of the luggage article 100.
  • the foldable portion 135 may be positioned adjacent the lower arm 142 of each rear wheel bracket 136A (e.g., substantially parallel to the lower arm 142).
  • the base 146 in a folded position, may be positioned adjacent the rear wall 104 (e.g., substantially on top of the rear wall 104 and/or the rear panel member 156).
  • the foldable portion 135 may be positioned adjacent the upper arm 140 of each rear wheel bracket 136A when in the collapsed or folded position. In a folded position, the foldable portion 135 may extend at an acute angle to, and preferably substantially parallel to, the fixed portion 137. Additionally or alternatively, because the lower arm 142 is stationary relative to the upper arm 140 of the rear wheel bracket 136A, the foldable portion 135 may extend substantially perpendicular to the lower arm 142 when the base assembly 134 is in a folded position.
  • a user may first actuate the lock system 152 of the rear wheel brackets 136A to selectively unlock the foldable portion 135 of the base assembly 134 relative to the fixed portion 137 as described above.
  • a user may then fold the base assembly 134 by rotating the foldable portion 135 relative to the fixed portion 137.
  • the foldable portion 135 may be rotated towards the fixed portion 137 to substantially collapse the luggage article 100 (see Fig. 4 ).
  • the foldable portion 135 may rotate away from the lower arm 142 of the rear wheel bracket 136A (see Figs. 4 and 6 ).
  • Rotation of the foldable portion 135 towards the fixed portion 137 transversely collapses and/or reduces the size of the gap G between the base 146 and the rear panel member 156 (see Figs. 8 and 9 ).
  • a user may continue to rotate the foldable portion 135 towards the fixed portion 137 until, for example, the foldable portion 135 contacts a portion of the luggage article 100 (e.g., the upper arm 140 of each rear wheel bracket 136A), thereby defining the folded position of the base assembly 134.
  • the foldable portion 135 may not contact a portion of the luggage article 100 to define the folded position of the base assembly 134.
  • the folded position of the base assembly 134 may be defined as when the base 146 contacts the rear panel member 156 or when the terminal end of the bearing member 163 contacts a portion of the fixed portion 137.
  • Opening the base assembly 134 may be accomplished in reverse order as that described above. For example, a user may first pivot the foldable portion 135 away from the fixed portion 137 of the base assembly 134 until the lock system 152 of the rear wheel bracket(s) 136A secures the foldable portion 135 relative to the fixed portion 137, as described above.
  • the lock system 152 may be operable to auto-engage (e.g., the sliding member 176 of the detent 174 auto-engages the blocking member 180 of the lower arm 142) upon rotation of the foldable portion 135 to the open position.
  • the lock system 152 may require manual manipulation to seat the sliding member 176 against the blocking member 180. For instance, once the foldable portion 135 is in a desired position relative to the fixed portion 137, the actuator portion 178 may be manually slid towards the blocking member 180 to seat the sliding member 176 into or against the blocking member 180.
  • Figs. 1-9 illustrate a base assembly 134 having one base 146 interconnecting four wheel assemblies 138
  • the base assembly 134 may include any number of bases, for example two bases 146.
  • each of the two bases 146 may connect one rear wheel bracket 136A to one front wheel bracket 136B.
  • the two bases 146 form independent and parallel arm elements 182.
  • Each arm element 182 may pivot independently from the other arm element 182 to provide a greater number of open and/or folded configurations of the base assembly 134 and/or luggage article 100. As shown in Figs.
  • each arm element 182 which may generally have a substantially rectangular cross section, may be as wide as the rear and/or front wheel brackets 136A, 136B. Each arm element 182 may attach to opposing sides 190 of the rear wheel bracket 136A. In this manner, the arm elements 182 may be stronger and encompass the lock system 152 and/or the first pivot axis P.
  • the front wheel brackets 136B may be pivotally connected to the arm elements 182 such that the front wheel brackets 136B may be rotated between open and folded positions.
  • the front wheel brackets 136B may be pivotally attached to the distal end or edge 150 of the base 146 at a second pivot axis.
  • the second pivot axis may be positioned parallel to the first pivot axis P and adjacent the lower front edge 118 of the luggage article 100.
  • each front wheel bracket 136B may be lockable in the open and/or closed positions.
  • each front wheel bracket 136B may include a lock system 252 similar to the lock system 152 described above with reference to the rear wheel brackets 136A.
  • each front wheel bracket 136B may be configured to include a similar spring-loaded detent 278 that selectively locks and unlocks the front wheel brackets 136B relative to the arm elements 182 (e.g., into or against a similar blocking member 280 in the lower arm 142 of the rear wheel bracket 136A).
  • Other locking mechanisms may also be used on or in connection with the front wheel brackets 136B in some examples.
  • the embodiment shown in Figs. 10 and 11 may be substantially equivalent to those described in Figs. 1-9 .
  • the base assembly 134 and/or luggage article 100 may include strengthening features operable to increase torsional rigidity of the base assembly 134 and/or the luggage article 100.
  • two connection members 154 may join the front wheel brackets 136B to the foldable portion 135 of the rear wheel brackets 136A.
  • terminal ends 155 of each connection member 154 may attach to one front wheel bracket 136B and an adjacent rear wheel bracket 136A (see Fig. 3A , for example).
  • the connection members 154 may extend adjacent the base 146 (e.g., substantially parallel to an edge of the base 146).
  • connection members 154 may increase the torsional rigidity and strength of the foldable portion 135 and/or the bottom end wall 112, especially for luggage articles of increased depth.
  • the connection members 154 may generally be a pultrusion rod having a substantially rectangular or circular cross section.
  • Figs. 2A-7 illustrate a connection member 154 attached to the rear and front wheel brackets 136A, 136B, it is contemplated that the rear and front wheel brackets 136A, 136B can be attached only to the base 146 (i.e., without the connection members 154).
  • pultrusions 160A, 160B may extend vertically from the fixed portion 137 (e.g., from the upper arm 140) to form a frame defining longitudinal corners of the luggage article 100.
  • at least one reinforcement cross member 162 may be attached between the pultrusions 160A, 160B at a location spaced away from the fixed portions 137.
  • Each reinforcement cross member 162 may extend laterally across the rear wall 104 of the luggage article 100 substantially parallel to the first pivot axis P.
  • the frame defined by the pultrusions 160A, 160B and the at least one cross member 162 may be integrated with the front, rear, and side walls 102, 104, 106, 108 of the luggage article 100 as conventionally known.
  • At least one backboard 164 may be connected to the base 146, the rear panel member 156, the pultrusions 160A, 160B, and/or each reinforcement cross member 162.
  • the backboard 164 which may be constructed of a flexible material adapted for resilient deformation, is a component of the rear wall 104 and/or the bottom end wall 112.
  • the backboard 164 may have a first portion 166 extending adjacent the rear wall 104, and a second portion 168 extending adjacent the base 146.
  • the first portion 166 extends generally between the upper rear edge 114 and the lower rear edge 116
  • the second portion 168 extends generally between the lower rear edge 116 and the lower front edge 118 of the luggage article 100.
  • the second portion 168 may be sandwiched with the base 146 and the hard and/or soft outer material to define the bottom end wall 112 (e.g., between the base 146 and the outer material of the luggage article 100).
  • the backboard 164 is one continuous member having an arcuate third portion 170 between the first portion 166 and the second portion 168 that extends arcuately around the lower rear edge 116 to permit the base assembly 134 to move between open and folded positions.
  • the arcuate third portion 170 may define with the base 146 and the rear panel member 156 a cavity 172 extending transversely between the two rear wheel brackets 136A (see Fig. 8 ). When moving from an open position to a folded position, the cavity 172 may collapse transversely (see Fig. 9 ).
  • a top portion 174 of the extendable handle 132 may be connected to the backboard 164.
  • each reinforcement cross member 162 may increase the torsional rigidity of the backboard 164 to avoid twisting of the extendable handle 132 during spinning of the luggage article 100 by a user.
  • the extendable handle 132 also strengthens the structure of the backboard 164.
