Definitions

  • This invention relates to improvements in folding containers. In particular, it relates to improvements in containers for air transport.
  • Air freight containers are used store and transport freight such as packages, perishable goods, mail and the like for loading onto cargo and passenger planes. Such containers are pre-loaded with cargo and subsequently loaded onto aircraft to reduce the time it takes to load the aircraft and to ensure that all available space in the aircraft is utilised. Air freight containers also protect the cargo from rain and snow during the aircraft loading process.
  • air freight containers are typically shaped to make the most of the available space.
  • One of the most common type of air freight containers is in the shape of a cube with a trapezoidal extension at one end to generally conform to the shape of the curved side walls of an aircraft's cargo hold.
  • Such air freight containers are also known as "unit load devices". Such containers have been used by the airline industry for about thirty years.
  • Air freight containers are light, typically weighing about 80Kg. Because they are lightly built, they are easily damaged and often have to be taken out of service for repair, typically at least twice a year.
  • US 5,941,405 proposes one such collapsible container.
  • the proposed container has an aluminium base and top but collapsible fabric side walls.
  • US 6,299,009 also discloses a proposed design of collapsible air freight container but which, when collapsed, is not particularly compact.
  • a first broad aspect of the present invention provides a collapsible air freight container having rigid walls a base and a lid and a side extension assembly in which when collapsed, the components all locate on top of the base in a compact manner.
  • the invention provides a collapsible folding freight container for air transport, having an erected state and a collapsed or folded state, the container comprising: a base; a side panel mounted to the base such the side panel may be folded over the base; an end panel mounted to the base such the end panel may be folded over the base; a side extension assembly including a frame and a collapsible side extension, the side extension having an erected configuration and a collapsed configuration and wherein in the collapsed configuration the side extension and frame may be folded over the base; and a lid slideably mounted between two of the frame, the side panel and the end panel and being pivotable relative to the other of the two panels or frame, wherein when the end panel is folded over the base the lid locates above the other of the two panels or the frame.
  • the side extension includes: a pair of end panels which are pivotally mounted to opposed vertical sides of the frame; a side extension lid; and side extension panels which are mounted to lower horizontal members of the frame and/or the side extension lid and/or each other.
  • the side extension lid is hinged to the upper member of the frame
  • a first upper side extension panel which is generally vertical in use when the container is erected, is hinged to the side extension lid
  • a sloping side wall panel which is oriented at an angle between vertical and horizontal in use when the container is erected, is hinged to the lower horizontal member of the frame
  • a side wall extension panel is hinged to the sloping side wall panel.
  • any side extension components all locate inside the frame.
  • the side extension is generally trapezoidal in cross-section.
  • the end panels of the side extension define L shaped edges for supporting edges of the side panels.
  • the lid is slideably mounted between the frame and the side panel and is pivotable relative to the back panel, wherein when the end panel is folded over the base, the lid locates directly above the back panel.
  • he base may define upstanding corner posts.
  • the corner posts may be omitted.
  • the side panel is mounted to the base by means of slideable hinges and can be lowered onto the upper surface of the base.
  • the side wall When collapsing the container, the side wall may be lowered onto the base, the collapsed frame and side extension assembly may locate on top of the side wall, the back wall may locate on top of the side extension and frame and the lid may locate on top of the back wall.
  • the lid in the collapsed state, lies preferably below the top of the corner posts to improve the stacking characteristics of the collapsed container.
  • a pair of spigots depend from the lid and slideably locate in channels defined near a top edge of the side panel and frame respectively and wherein a pair of recesses are defined in the top of the back panel which when the container is in the erected state are aligned with one of the channels to allow the spigots to be slid along the channels and into the recesses.
  • the invention provides a collapsible folding freight container for air transport, having an erected state and a collapsed or folded state, the container comprising: a base; a side panel mounted to the base; an end panel mounted to the base; a side extension assembly including a frame and a collapsible side extension, the side extension having an erected configuration and a collapsed configuration and wherein in the collapsed configuration the side extension and frame may be folded over the base; and a lid which in the erected state locates on an may be supported by the side panel, end panel and the frame; and wherein the side extension assembly further comprises; a pair of end panels which are pivotally mounted to opposed vertical sides of the frame; a side extension lid; and side extension panels which are mounted to lower horizontal members of the frame and/or the side extension lid and/or each other, the arrangement being such that in the collapsed state the end panels and side extension lid and panels locate within the frame.

  • the structural members define the top, side and bottom edges of the frame 22.
  • the frame 22 is hinged to the base 12 by hinges 21 (best seen in Figure 10).
  • the frame interlocks with the back panel 18 when the container is in the erected state.

Abstract

La présente invention concerne un conteneur de fret aérien pliable (10), également connu sous le nom de dispositif d'unité de chargement, qui comporte une base standard (12) couramment utilisée sur des dispositifs d'unité de chargement, un panneau latéral (16) articulé de manière coulissante avec la base et un panneau arrière (18) qui est articulé avec la base et verrouillé sur le panneau latéral. Il existe une extension latérale (20) de forme généralement trapézoïdale pour s'adapter approximativement à la forme d'une paroi latérale de soute d'aéronef. L'extension latérale (20) comprend un cadre (22), qui est articulé avec la base, et deux extensions de panneau (avant et arrière) trapézoïdales (24, 26) articulées avec le cadre. L'extension latérale (20) est terminée par un couvercle (28) et une paroi latérale (32) est reliée par une charnière (34) au couvercle (28) articulé avec la partie supérieure du cadre, et par un panneau de fond incliné (36) et un panneau latéral relativement court (40) reliés l'un à l'autre par des charnières au panneau de fond (36) également articuléà un élément de fond du cadre. Un couvercle est monté coulissant sur une partie supérieure du conteneur de sorte qu'il peut coulisser par rapport au panneau arrière. Lorsqu'il est entièrement rétracté à l'arrière du conteneur par rapport au panneau arrière, le couvercle est disposé de manière à pouvoir pivoter pour recouvrir le panneau arrière. Comme c'est généralement le cas avec des dispositifs d'unité de chargement, l'avant du conteneur est ouvert mais peut être recouvert par un rideau souple ou analogue. Le conteneur peut être plié par rétraction et pivotement du couvercle pour recouvrir le panneau arrière (18), ce qui plie l'extension latérale (20) à l'intérieur du cadre (22), plie et en fait coulisser le panneau latéral (16) dans la base (12) et abaisse l'extension latérale (20) pliée puis le panneau arrière (18) et le couvercle (40) dans la base.
