Definitions
- the present invention relates to a freight container having sides oriented perpendicularly to each other and de- fining an internal cargo space, and having an access opening allowing access to said cargo space, said access opening being surrounded by substantially straight sections of a channel-shaped first groove, said sections being oriented perpendicularly to each other, said groove extending in a plane which is substantially parallel with the access opening, wherein said freight container has separate groove connection devices with a groove having a cross-sectional shape corresponding essentially to the first-mentioned groove and which forms a continuously extending, smooth transition between said sections of the groove .
- Such a container wherein straight sections of a groove are formed on the internal surface of the horizontal and vertical elements in a frame that encloses an access opening at the end of the container.
- the groove connection devices are secured by welding to the frame and thereby enable attachment of a film across the access opening, the edges of the sheet being inserted into the groove for subsequent fixing by means of a flexible plastics strip that is pressed into the groove.
- the groove connection devices it is possible, in a simple manner, to ensure a tight connection between the film and the groove at the inner corners of the container where the straight sections of the groove meet. Because of the smooth transition, the plastics strip, which has a shape adapted to the cross-section of the first groove, may thus be received in a continuously extending, annular groove that has a uniform cross- section, without being given sharp bends.
- the groove connection devices comprising engagement means that are shaped comple entarily with the groove and adapted for providing a mechanical engagement with two adjoining sections of the groove.
- the groove connection device can made of eg a plastics material.
- the groove connection devices have a groove that forms a curved transition between the straight sections.
- the groove connection devices comprise a first part adapted to be engaged with the first groove and a second part adapted to prevent subsequent removal of the first part from the groove, and locking means for allowing releasable retention of the second part relative to the groove.
- the groove connection device being in releasable engagement with the groove on two adjoining sides enables replacement of damaged groove connection devices ' .
- the groove connection devices may advantageously be formed as featured in claim 7.
- Fig. 1 seen from the access opening, shows part of a freight container which is sealed by a sheet that extends across the access opening,
- Fig. 2 shows a horizontal cross-sectional view through the left vertical frame of the freight container in fig. 1, in the area at the access opening,
- Fig. 3 shows a detailed view of the joint between two frame elements that are incorporated in the freight container shown in fig. 1,
- Fig. 4 shows a partially exploded view of the corner joint shown in fig. 3, and
- Fig. 5 shows a vertical cross-section through the joint shown in fig. 3.
- the reference numeral 1 shows the end of an elongated freight container that is, in the embodiment shown, preferably provided with a cooling device (not shown) for establishing a desired temperature interiorly of the freight container.
- the freight container 1 has sides in the form of parallel and vertical walls 20, a horizontal bottom, a horizontal ceiling 10 and an end wall (not shown) .
- the freight container 1 has two annular vertical frames 30, 40 at the shown end that combine to define an access opening to the freight container 1. This access opening may be closed by means of doors 5 that are secured to the outer frame 30 of the two frames by means of hinges 31, the other frame 40 of the two frames being arranged internally in the first- mentioned frame 30.
- the doors 5, together with the sides 10, 20 and the end wall, are preferably provided with a suitable insulation for maintaining the desired temperature in the interior of the freight container.
- the freight container 1 is provided with a flexible plastics sheet 7 that extends across the access opening and that greatly seals the atmosphere in the freight container 1 from the outside when the doors 5 are closed, in a conventional manner.
- Fig. 2 shows an enlarged view of a horizontal cross-section through the one vertical wall 20 of the freight con- tainer 1, more particularly the wall that is not visible in fig. 1.
- the wall 20 has an outer cladding 22 and an inner cladding that has a surface 24 directed towards the interior of the freight container 1.
- An insulating material 26, preferably a foamed material, is arranged between the outer cladding 22 and the inner cladding.
- a vertically extending element 32 of the frame 30 is connected with the outer cladding 22 via a weld 21, and the inner cladding is connected via a weld 25 to a vertical frame element 41 that is incorporated in the frame 40.
- the figure merely represents a preferred embodiment where the two frames 30, 40 are movably interconnected by a gasket 33, as is described in European Patent No. 731 768 which is hereby incorporated in the present text by way of reference.
- Fig. 2 moreover shows that the surfaces facing inwards towards the interior of the container 1 are formed with an elongated channel-shaped first groove 43 that is defined outwardly by two locking flanges 45, 46.
- the locking flanges 45, 46 define a longitudinal access passage to the groove 43 that, as shown, expands immediately behind the locking flanges 45, 46, and preferably converge again in a direction towards the bottom of the groove 43.
- the groove 43 may be formed integrally with the frame element 41 in the internal frame 40 and preferably extends uninterruptedly around the entire access opening.
- the groove 43 may be formed in the inner cladding at a de- sired distance from the access opening, or the groove 43 may be formed in the frame 30, e.g. if an internal frame 40 is not used. Further, if desired, the groove may be formed such that the access passage is oriented in a direction toward the access opening.
- the groove 43 serves to fix the edge 7' of the above-mentioned sheet 7 in the access opening in a conventional manner, there being used a flexible strip 8 of a plastics material for this purpose which is pressed into the groove 43 after insertion of the edge 7' in the groove 43.
- the shape of the groove 43 behind the locking flanges 45, 46 may be selected to facilitate this press- ing-in.
- the strip 8 preferably has a length corresponding to the perimeter of the access opening, and the strip 8 may be pulled out to release the sheet 7 when access to the interior of the freight container 1 is desired.
- Fig. 3 shows an inner corner of the frame 40, where the vertical frame element 41 shown in fig. 2 is connected, e.g. by welding, to a corresponding horizontal frame element 41' which is intended to be connected with the bottom of the freight container 1.
- the two frame elements 41 and 41' are interconnected via a groove connection device 50, which may be adapted to impart a certain rigidity to the joint of the frame elements 41, 41'.
- the groove connection device 50 is secured to the groove 43 in a releasable manner, and at the top the groove connection device 50 has a curved groove 51 which is shaped so as to form a continuous transition between the groove 43 extending on the vertical frame element 41 and the groove 43 extending on the horizontal frame element 41'.
- the second groove 51 has essentially the same profile as the groove 43, and the groove connection device 50 may thus receive the sheet 7 and the strip 8 at the shown joint. It appears that, according to the shape of the groove 43, the locking flanges 45, 46 in the frame elements 41, 41' may also be provided with recesses 49 which, to a greater extent, allow unobstructed insertion of the strip 8 at the transition between the groove 43 in the frame elements 41, 41" and the groove 51 of the groove connection device 50. Because of the curved expanse of the groove 51 it is ensured that the strip 8 is not given a sharp bend.
- the groove connection device 50 is shown in greater detail, and it appears that the groove connection device 50 is composed of three separate parts, viz. a first part 52, a second part 65 and a third part 60. Each of these parts has a through hole 53, 66 and 61, respec ⁇ tively, and the three parts may be interconnected by means of a transverse pin (not shown) that may be passed through the holes 53, 61 and 66 when the parts are arranged side by side as shown in fig. 3.
- Each of the parts 52, 65 and 60 has a curved side edge, and these curved side edges together form the curved upper groove 51 of the groove connection device 50.
- the first part 52 and the third part 60 are provided with hook-like projections 54, 62, by means of which these parts may be caused to engage the groove 43, and with locking flanges 45', 46' .of a shape corresponding to the shape of the locking flanges 45, 46 of the groove 43.
- the hook-like projections 54, 62 which will be seen more clearly in fig. 5, are arranged along each of the two edge sides of the parts 52, 60 that extend along the vertical frame element 41 and the horizontal frame element 41', respectively.
- the first part 52 and the second part 60 may moreover be provided with incisions that serve the same purpose as the recesses 49.
- the groove connection device 50 is shown in the mounted state, where the groove connection device 50 is kept engaged with the groove 43 on the horizontal frame element 41' as well as the vertical frame element 41. It will be seen here how the locking hooks 62, 54 on the first part and the third part, respectively, of the groove connection device 50 are engaged with the locking flanges 45, 46 that define the horizontal and the vertical groove 43 outwardly.
- the mounting of the grove connection device in the groove 43 is more particularly carried out in that the first part 52 is inserted into the groove via the access passage between the locking flanges 45, 46 and are moved laterally, such that the locking hook 54 of the part engages the rear side of the locking flange 45 of the groove 43, both in the vertical frame element 41 and in the horizontal frame element 41'.
- the third part 60 is inserted into the groove 43 in a corresponding manner.
- the second part 65 of the groove connection device 50 is inserted into the space between the first part 52 and the third part 60.
- the second part 65 is preferably formed with a width corresponding to the space. In this position, the first part 52 and the third part 60 are prevented from being moved laterally backwards.
- the second part 65 is finally fixed by means of the above-men- tioned transverse pin, which is inserted through the holes 53, 61, 66 and is secured, e.g. by means of a nut. It- should be stressed that the second part 65 may very well be fixed in another manner, e.g. by snapping on.
- the invention primarily serves to provide a groove for retaining the mounting strip 8 at the inner corners of the freight container 1
- the groove connection device 50 may also be used for imparting increased strength to the frame 40 at the corners, and that, in this case, the groove 43 may merely be necessary in the area at the corners of the freight container 1.
- the groove 43 in the frame elements 41, 41' may also be provided with stops that prevent relative displacement of the locking device 50 relative to the frame elements. It is hereby possible to connect the frame elements 41, 41' solely because of the engagement between the locking hooks 54 and the locking flanges 45, 46.
