DESCRIPTION:
BRIEF SUMMARY
The invention relates to a freight container for air transportation purposes having a bottom panel and arranged on this a support frame that features sections projecting from the bottom panel and transverse sections connecting said projecting sections, and also features planking that at least partly fills-in the frame and is fitted to flanges on the sections, the sections being interconnected at nodal points in the supporting frame, at least in part, by gusset-plates.
A freight container of this type is disclosed in the German patent publication DE-OS 21 19 536, wherein the sidewalls comprise two parallel, vertical posts connected by a ridge section. A projecting part of the ridge section bridges an area of the said wall running externally of the bottom panel, said area being enclosed in sections and having a sloping edge running from the bottom panel up to about half of the height of the sidewall.
This shape of freight container can be accommodated in the round or oval cross-section of an aircraft fuselage and is mandatory for air freight containers.
A disadvantage of this prior art is that the differently shaped sections can be held together at the nodal points only at considerable expense and by suitable deformation of the gusset-plates.
In view of the above the object of the invention is to simplify the construction of such a freight container.
This object is achieved by way of the invention in that the gusset-plates are flat and are secured to flanges on the sections, said flanges being in-line with a wall of the section which is thus extended away from a hollow part of the section.
The design of the sections according to the invention means that deformation of the gusset plates is no longer necessary even when joining sections at angles greater or smaller than 90.degree.. This becomes possible by the flange extensions of a wall section. Special protection is sought for this idea of extending the section wall on one or both sides by flanges for use in air-transport containers, as this design is unusual in containers; flanges have hitherto been formed in an outer surface of a sidewall and run therefore along the centerline of the cross-section. Shifting these flanges into the plane of a sidewall leads to an extraordinary improvement in the overall design of the freight container.
Further advantages, features and details of the invention may be gathered from the following description of preferred examples of embodiment and with the aid of the drawings attached herto, wherein:
FIG. 1 is a perspective view of a freight container for air transport;
FIG. 2 is a side elevation of FIG. 1;
FIG. 3 is a schematic section along the line III--III in FIG. 2;
FIG. 4 is a schematic section along the line IV--IV in FIG. 2;
FIG. 5, 6 show enlarged parts from FIG. 3 in cross-section;
FIG. 7 is an enlarged section from FIG. 1 in cross-section.
A freight container 9 for air transport features a bottom panel 11 with connecting strips 10 and mounted on the said panel a support frame comprising two side frames each of two vertical sections 12, 13 a ridge section 14, 15, a short frame section 16 running downwardly therefrom, and from that an inclined section 18 set at an angle w. The two sideframes 12, 13 are connected by transverse sections 20 and are filled-in with metal sheets 22.
The sections 12 to 16, 18 are joined together and to the connecting strips 10 of the bottom panel 11 by means of flat gusset-plates 30. According to FIGS. 5, 6 and 7, in order to avoid deforming the gusset-plates 30, the vertical sections 12, 13, and ridge-sections 15, are of special design; they are in the form of rectangular hollow sections having sidewalls 28, 29 of external length a of 35 mm, for example, and thickness b of 1.4 mm. The sidewall 29 in FIG. 5 is extended on both sides beyond the hollow section by flange 27 by a length e=23 mm to provide an overall length i of 81 mm. In the example shown in FIGS. 6 and 7 an extension is provided on only one side by a flange 27 to give an overall length i of wall 29 to 27, in this case=58 mm.
