Definitions

  • the conventional containers for freight transport are comprised of a box made of different materials such as wood, aluminum, iron, reinforced plastics and so forth, that is a rectangular parallelepiped box of standardized sizes, having a door at one of the short sides.
  • a container is transferred in a loaded condition, as a unit, from a transportation means to another and commercially available containers have a rigid structure, so that their overall dimensions are the same either in the loaded or empty condition.
  • An object of the present invention is to provide means "for considerably reducing container dimensions, when it has to be transported in an empty or inoperative condition, up to a little partof its loaded volume (about one fifth), .with an easy and rapid operation.
  • Another object of the present invention is to allow a very rapid replacement of each of the elements of the container, without requiring skilled personnel of a special workshop, as the container consists of several elements connected to each other by means allowing an easy detachment in the event of damages.
  • a container according to the present invention in which the lid is detached from the remnant structure, the. side walls are collapsible on the bottompanel, and suitable locking and hinge means are provided.
  • FIG. 3 is a perspective view of the container with collapsed walls, thus reduced for transport in an empty condition
  • FIG. 4 is a cross-sectional elevational view taken along line 4-4 of FIG. I.
  • FIG. 5 is a sectional detail of the sealed hinge connection between a wall and the bottom panel.
  • the container according to the present invention is comprised of a plane bottom panel 2, the short edges of which are connected through hinges 7 to a frame formed by a front frame 1 provided with doors I and a rear wall 3.
  • the hinges 7 connecting frame I and wall 3 with panel 2 are mounted flush with the upper surface of the bottom panel 2, so that during their collapsing stage said elements I and 3 turn
  • the sidewalls 4 and 5, respectively are mounted by means of hinges 10.
  • the upper lid 6 is comprised of a cover plane mounted on a peripheral frame and abuts on the walls I, 3, 4 and 5 by means of suitable projecting edges.
  • a plurality of inner and outer recesses are provided along the two long sides of the lid peripheral frame and of the shoulders 8 and 9 integral with the bottom panel frame.
  • the inner recesses I4 are designed for receiving a number of tie rods 15 serving both as aiconnection of lid with bottom and as stiffeners of the structure when loaded.
  • the outer recesses 13 are intended for packing the collapsed container during transport in the empty condition by means oftie rods 1], II, II".
  • the container has also the conventional, standard type corner blocks 12 for receiving the hooks of a hoisting apparatus.
  • seals 16 are also provided for avoiding moisture to enter the container, with the aid of an outwardly and downwardly inclined gap 17 between shoulders and the corresponding sidewalls.
  • the operation of collapsing the container into the reduced volume empty transport condition is very easy and is as follows: the inner tie rods 15 are detached; lid 6 is raised by a suitable hoisting apparatus; front wall 1 and rear wall 3 are collapsed and in the gap remaining on the bottom panel 2 between said collapsed walls 1 and 3, said tie rods 15 are stored; then sidewall 4 is folded down, overlapping walls I and 3; then side wall 5 is folded down, overlapping all the preceding walls; at last lid 6 is lowered on top of'the collapsed unit and the whole collapsed container is locked by means of anchoring tie rods ll, 11', 11" in the outer recesses 13.
  • the empty container may now be hoisted and transported at will.
  • the collapsing operations may be carried out manually, since the joint strength of two men is quite sufficient, or by a hoisting apparatus acting on suitable connections provided on the outer side of the walls.
  • a collapsible freight transport container structure the type having a removable lid, a bottom panel having parallel flanges extending transversely upward from two parallel edges thereof, sidewalls connected to said flanges for movement downwardly toward said bottom panel, end walls connected to the remaining two parallel edges for 90 movement downwardly toward said bottom panel wherein the improvement comprises:
  • flanges with their upper surfaces having a generally truncated shape capable of being hingingly connected to a mating sidewall surface forming an outwardly and downwardly inclined gap between each flange and its corresponding side wall;
  • sealing means positioned in said sidewall surface and extending into direct contact with the apex of said truncated flange surface for preventing the entry of moisture into said container through said flange and side wall gap when the container is in its erected condition;
  • said removable lid having edges formed as fitted surfaces to engage the side and end walls and lock the same in position when the container is in its erected condition and to fit over and secure in position the side and end walls that are folded 90 in the collapsed condition of the container;
  • hinge means interconnecting said sidewalls and end walls to said bottom panel and recessed within the upper surface of said bottom panel to be flush therewith by virtue of the construction of which the volume of said container in the stacked condition is about one-fifth of its volume in its erected condition.
  • said flanges have a first plurality of recesses arranged along the outer surfaces thereof;
  • said removable lid has a second plurality of recesses equal in number to said first plurality of recesses arranged along the outer surfaces of the edges of said lid which are parallel to said flanges;
  • outer tie rods are connected between each of one of said first plurality of recesses and one of said second plurality of recesses on the corresponding side of the container when said lid is placed upon said collapsed container whereby said container is held in its collapsed condition;
  • said removable lid has a second plurality of recesses equal in number to said first plurality of recesses arranged along the outer surfaces of the edges of said lid which are parallel to said flanges; and outer tie rods are connected between each of one of said first plurality of recesses and one of said second plurality of recesses on the corresponding side of the container when said lid is placed upon said collapsed container whereby said container is held in its collapsed condition 3.
  • a collapsible freight transport container structure as defined in claim 1 wherein:
  • said flanges have a first plurality of recesses arranged along the inner surfaces thereof;
  • said removable lid has a second plurality of recesses equal in number to said first plurality of recesses arranged along the inner surfaces of the edges of said lid which are parallel to said flanges;
  • inner tie rods capable of sustaining the container in an erected condition under external forces of tension or compression, connect one of said first plurality of recesses of one of said flanges to one of said second plurality of recesses in said lid edge on the corresponding side of the container whereby said lid is maintained in its correct position relative to the container bottom and the container side walls are provided with additional support.
