Description
- The invention relates to a transportable container, especially one which is built of lightweight but strong frame members. One use of a container of the invention is as an ISO Standard refrigerated or dry container of the type carried on ships, aeroplanes, lorry trailers or rail wagons and the like.
- It is one object of the invention to provide a container with a high degree of thermal insulation: it is another object to provide a container of relatively lightweight; and yet another object is to provide one which has high corrosion resistance.
- FR-A-2249257 discloses a transportable container comprising a frame formed of elongate frame members having a cladding secured thereto wherein at least one of the frame members includes a thermal break along at least a portion of its length.
- In one aspect there is provided a transportable container comprising a frame formed from frame members joined together and having a cladding secured thereto, at least one of the frame members including a thermal break along at least a portion of its length, characterised in that at least one of the frame members comprises two lengths of metal which are joined together along a common edge by a bridging member formed from a thermally insulating material to define the thermal break between the two lengths.
- Elongate reinforcing elements formed from, e.g. lengths of steel or stainless steel tubing may be mounted adjacent the frame members to strengthen the frame. Preferably, the frame members are of generally box-cross section and the reinforcing elements are mounted within the hollow interior of the frame member. In an especially preferred embodiment the frame members are of box cross-section and three such members are joined together at least at one corner of the frame by a connector having three orthogonal projections which engage the facing end of the respective frame members, the projections having pegs which are received within the facing end portion of the tubular reinforcing element.
- DE-A-2624928 discloses a container having corner connectors faces of which have projecting arms arranged to be received in the end portions of hollow box section frame members.
- Preferably the frame members are hollow, and refrigeration apparatus mounted on the container is adapted to pass temperature controlled gas through at least one of the hollow frame members from the apparatus through vent means.
- The interior of the container may be provided with a flat floor, and still have adequate circulation of cooling air, in contrast to known structures where supplementary ducting is required on the floor, e.g. a corrugated floors. This gives an increase in useful interior space and saves weight. In this way a dry container may be provided which is of light weight, but which is also strong.
- In order that the invention may be better understood, it will now be described with reference to the accompanying diagrammatic drawings, in which:
- Figure 1
- is a perspective view of the frame less the cladding;
- Figure 2
- is an elevation of one container end wall housing refrigeration apparatus;
- Figure 3
- is an elevation of the container end wall having the doors in an open condition;
- Figure 4
- is the same as Figure 3, with the doors in a closed condition;
- Figure 5
- is a sectional view along line A-A of Figure 4;
- Figure 6
- is a sectional view along line B-B on Figure 4;
- Figures 7-13
- show cross-sections of different section lengths
- Figure 14
- is a perspective view of a corner connector; and
- Figure 15
- is a cross-sectional view of a corner connection.
- As best shown in Figures 1 to 6 a transportable container 1 is made from a cladding comprising e.g a sandwich of steel, aluminium or
stainless steel sheeting 2 with afiller 3 of insulating material, which is applied to a rectangular box-like frame 4 made from elongatestructural members 5 joined together. Theouter sheeting 2 may be corrugated or rigidised for extra strength. The container 1 has a pair ofdoors 6 at one end. At the other end, refrigeration apparatus of known type comprising a compressor 7 and associated circuitry is mounted within the frame 4. Agoose neck tunnel 8 extends inwardly from thelower frame member 5 beneath the compressor, and a pair offork pockets 9 extend across the bottom side members of the container to receive the blades of a forklift truck. A pair offans 10 circulate air through the refrigeration circuitry and return the temperature controlled cooled or hot air to the interior of the container. - Referring to Figures 7 to 13, sectional views of a variety of
structural members 5 of the invention are shown. Eachmember 5 is of generally box-section shape and is made from two or more parallel lengths of roll formed stainless steel. The lengths of Figures 7-12 are separated along their length at two locations to define thermal breaks. A pair ofelongate bridging members 11 made from, e.g unplasticised polyvinylchloride each have a pair ofslots 12 shaped to receive the complementary edges of the two lengths to hold themember 5 together. Thebridging member 11 also defines afurther slot 13 shaped, e.g to receive arubber gasket seal 14. Aflange 15 extends from one or more of the walls of themember 5, e.g to provide an anchorage for thecladding slot 20, e.g to receive arubber gasket seal 21. - The members of Figures 11 and 12 are deeper than the others and are for use as the lower side frame members, and are arranged so that when the container is on the ground, a defined gap is present between the lower frame member and the ground.
- The length of Figure 13 has no thermal break, but is otherwise similar to the length of Figure 7. The length of Figure 13 may be used, e.g as one of the frame lengths of a dry or non-refrigerated container where the requirements of low weight and high strength are just as useful.
- Elongate reinforcing
elements 22 comprising, e.g lengths of steel or stainless steel cylindrical tubing extend within themembers 5 of Figures 8 and 10 to 13. Aclearance 23 is present between the inside wall of themember 5 and the reinforcingelement 22 and thisclearance 23 may be left empty or filled, e.g with a thermally insulating foam material. - As shown in Figure 1 the frame 4 includes two longer
side top members 5a made from lengths according to Figure 10 andlower side members 5b made from lengths according to Figure 12. The rear compressor end wall comprises vertical andhorizontal cross members 5c formed from lengths according to Figure 10. The door end wall includes outer vertical side and upperhorizontal members 5d formed from lengths according to Figure 8 and a lowerhorizontal member 5e formed from a length according to Figure 11. Transverse and verticalstructural members 5f according to Figure 10 are welded to the frame forwardly of the compressor end wall. - The detail of a rearmost bottom corner connection is shown in Figures 14 and 15. A
corner connector 25 is generally cube-shaped and has three orthogonalbox section projections 26 from which extendcylindrical pegs 27, so that eachprojection 26 andpeg 27 is shaped to complement the adjacent facing end of themember 5. A furthercylindrical peg 27 extends upwardly from one face of the connector 25 (the top as shown) adjacent aprojection 26. Thecorner connector 25 is inserted so that eachpeg 27 is received as a press fit within an adjacent reinforcingelement 22 and thebox section projection 26 is received within themember 5 and welded thereto. The presence of thesecond peg 27 on one face means that two reinforcingelements 22 may be placed vertically side-by-side at each corner of the frame, which ensures that a container can support the weight of many such containers stacked one above the other. - In one embodiment, holes (not shown) are provided within the walls of the
longer side members 5b where they join the lowertransverse member 5f. A further hole (not shown) in the lowertransverse member 5f is in communication with one of thefans 9 so that cooled air may enter thetransverse member 5f and then pass through both of thelower side members 5b. Further holes 30 (Figure 3) communicate between the door ends oflower side members 5b and the interior of the container. The cooled air may be arranged to pass along the reinforcingelements 22, or along thespace 23. In such a case the container may include a flatstainless steel floor 31. In another embodiment, as best shown in Figure 12, the floor may comprise a corrugated stainless steel sheet or an aluminium "Tee"floor 32, which with a stainless steel sheet 33, sandwiches a layer of thermally insulating material 34. In this embodiment cooled air flows along the corrugations. Thesandwich 32, 33, 34 may be installed as a complete unit to rest upon theflanges 14 of thelower side members 5b and may be adhered or riveted in place. - Figures 3, 4, 5 and 6 show the container wall having two
doors 6 withhinges 35 and alocking mechanism 36. Thedoors 6 have two outer vertical andhorizontal members 5g according to Figure 7; the left hand door has an innervertical member 5h according to Figure 9 and the right hand door an inner vertical member 5i according to Figure 7. Agasket seal 21 is fixed in aslot 20 of theouter members 5d of the wall. Thegasket 21 is seated behind aflange 15 of the outervertical members 5g of thedoor 6. Further gasket seals 14 are received inslots 13 of the adjacentouter door members 5g and these seal against the opposing face of theouter frame member 5d. The innervertical side members 5h, 5i of the doors both havegaskets 21 which seal behindflanges 15 and afurther gasket 14 is received in aslot 13 in one of the inner vertical side members. Because thegaskets - The presence of the
thermal breaks 11 in theframe members 5 ensure that a complete thermal break may be provided between the inner and outer walls and that the container is especially well insulated. The stainless steel members and the reinforcing elements ensure that the frame is strong, light and corrosion resistant.
