Definitions

  • the present disclosure generally relates to luggage articles and, in particular, to the use of multiple separate portions or sections of hard side material in the shell structure of a luggage case.
  • Hard side luggage cases provide durability and support by using formable, relatively hard materials to create the exterior of the case.
  • hard side cases can be heavier than soft side cases.
  • soft side cases are often less durable than hard side cases, and their construction involves high labor input and material cost.
  • Hybrid luggage cases that include both hard side and soft side materials are often lighter than hard side cases, but also can be less durable.
  • Rolling luggage cases, in particular hard side luggage cases, over rough surfaces causes vibrations and noise and subjects the cases to impact forces.
  • Documents that may be related to the present disclosure in that they include various approaches to multi-piece luggage construction include US20130220755 , EP20130747635 , US20110186396 , US 20130213752 , and GB2415955 . These proposals, however, may be improved.
  • an improved luggage article and in particular an improved multi-piece hard side shell, that is lightweight, durable, can absorb an impact force, can maintain structural integrity under stress, and can reduce or minimize vibration and/or noise caused by its use.

  • the portions are joined by flexible joint structures, which may be resilient strip members (also referred to as joint members).
  • the resilient strip members may absorb or dissipate impact and forces transmitted between adjacent sections of the shell, which provides durability to the luggage article and minimizes noise production.

  • the joint structure includes a resilient bridge portion from which opposing channels extend to receive a respective peripheral edge region of adjacent moulded hard portions.
  • Each channel may be configured by a pair of spaced-apart arms extending from the bridge portion.
  • the outer portion of the joint member on the outside of the luggage case may include a side surface of a central portion of the bridge portion, one leg of one channel and one leg of the opposing channel.

  • the joint structure includes a resilient bridge portion 155 from which opposing channels 158, 161 extend to receive a respective peripheral edge regions 164, 165 of adjacent moulded hard portions 136, 140.
  • Each channel 158, 161 may be configured by a pair of spaced-apart arms 152 and 154, or 157 and 159, extending from the bridge portion 155.
  • the outer portion of the joint member 150 on the outside of the luggage case 100 may, in one example, include a side surface formed by the central portion 156 of the bridge portion 155, one leg 152 of one channel 158 and one leg 157 of the opposing channel 161.
  • the outer portion of the resilient joint member 150 may have a convex portion for a smooth outer contour.
  • the resilient joint or strip member 150 shown in each figure has common features described below.
  • the width of the channels 158 and 161 may accommodate the peripheral edge regions of the respective moulded portions having differing widths. Since the strip or joint member 150 may be flexible and resilient, the excess space in the channels may be taken up by the arms 152,154 flexing into contact with both surfaces of the moulded portion received in the channel 158, 161 when secured to the respective peripheral edge portions received therein.
  • the shape, length or thickness of the arms 152 and 154, or arms 157 and 159 may be the same or different.
  • any convex or protruding joint portions may alternatively be oriented towards the inner surface of the luggage article 100.
  • Joining moulded hard portions, for example 130, 132, 134, 136, 138, 140 or 172, 174 with a resilient strip members 150 may make assembly of the luggage article 100 easier because moulded hard portions 130, 132, 134, 136, 138, 140 of different thicknesses can be received by the same resilient strip member 150.
  • Any combination of the examples of the joint member 150 of the joint structure may be used in forming a single luggage shell.
  • Connection references are to be construed broadly and may include intermediate members between a connection of elements and relative movement between elements. As such, connection references do not necessarily infer that two elements are directly connected and in a fixed relation to each other.
