Definitions

  • the present invention concerns a support structure.
  • this invention concerns a support structure for a curtain side container.
  • the invention also concerns a container with a substantially open side, and a support structure associated with the open side.
  • a typical curtain side container comprises a base, a first end wall located at one end of the base, a second end wall located at the opposite end of the base, and a roof extending between the first end wall and second end wall.
  • at least one of the sides of the container is left largely structurally open, with a tarpaulin, or "curtain" extending along the open side of the container once loaded.
  • the length and weight of the roof may cause the roof of the container to sag, and it is undesirable to increase the weight of the container significantly by making the roof more rigid.
  • Typical container lengths/sizes are 20 foot, 40 foot, and 45 foot containers. The skilled person will appreciate that the containers may vary from these lengths, which are approximate only, but which are standard terms of the art. Additionally, to help constrain and contain the freight within the container, it may be necessary to add
  • vertically disposed support structures are added to at least one open side of a container, extending from the base of the container to the roof. To ensure that it remains straightforward to load and unload a container, these support structures are preferably movable along the length of the container, such that during loading they can be moved out of the way, and once loading is complete they may be moved back into a supporting position.
  • the support structures In order to stop the support structures moving once they have been put into a supporting position, they may be locked into place with a locking mechanism.
  • Various examples of locking support structures for containers may be found in EP1953068, EP0335427, and WO2010/010053.
  • the disclosed support structures include potential disadvantages, for example relating to the complexity of the locking mechanisms disclosed or the strength of support the support structures provide.
  • the present invention seeks to mitigate the above-mentioned problems. Alternatively or additionally, the present invention seeks to provide an improved support structure for a curtain-side container. Summary of the Invention

  • locking mechanism comprising a first locking pin and a second locking pin, wherein the first locking pin and second locking pin are engageable with the first receiving section and second receiving section respectively, via a clamping action, thereby locking the support structure into position with respect to the bracket.
  • a container according to this aspect of the invention advantageously provides an open side container with a support structure which may be locked into position by the clamping of the first locking pin and second locking pin to the bracket.
  • the support structure may be unlocked by unclamping the two locking pins from the bracket. When fully unlocked, the support structure may be disengaged from the bracket.
  • the support structure may be pivotally connected to the roof, allowing movement of the support structure away from engagement with the bracket.

Abstract

La présente invention porte sur une structure de support (10). Un conteneur de fret comprend une base, une première paroi d'extrémité et une seconde paroi d'extrémité à des extrémités opposées de la base. Un toit s'étend à partir de la première paroi d'extrémité jusqu'à la seconde paroi d'extrémité, et au moins un côté est sensiblement ouvert. Du côté ouvert, une structure de support (10) s'étend à partir du toit du conteneur vers la base du conteneur. Un support (16) est présent vers la base du conteneur, le support (16) comprenant une première section de réception (20) et une seconde section de réception (30), et la structure de support comprend un mécanisme de verrouillage (16) comprenant une première broche de verrouillage (18) et une seconde broche de verrouillage (26). La première broche de verrouillage et la seconde broche de verrouillage peuvent venir en prise avec la première section de réception et la seconde section de réception, respectivement, à l'aide d'une action de serrage, de façon à verrouiller ainsi la structure de support en position par rapport au support.
