DESCRIPTION:

BRIEF SUMMARY
The subject of the present invention is an improvement made to containers, in particular metal containers, of the type comprising two longitudinal lateral structural members as well as a plurality of support props hinged to the body of the container and rigidly attached to it.
Containers of this type are known per se.
However, they exhibit the essential drawback that the props, in the folded-up position, always project with respect to the volume of the container, which is a great drawback for using the latter and handling it.
The object of the invention is to remedy these drawbacks.
In accordance with the invention, for this purpose provision is made for an improvement made to containers, in particular metal containers, of the type comprising two longitudinal lateral structural members as well as a plurality of support props hinged to the body of the container and rigidly attached to it, characterised in that each prop, in the stored position, may be completed folded away into the lateral structural members of the container so as to leave no part projecting beneath the structural volume of the said container.
This device exhibits the advantage of being able to be fitted onto any existing container having lateral structural members, while respecting the constraints connected with the overall size for transporting by road.
The invention will be better understood with the aid of the description given hereinbelow with reference to the attached drawings in which:
FIG. 1 is a partial view, in lateral elevation, of a device in accordance with the invention in an in-use position;
FIG. 2 is a front view of FIG. 1;
FIG. 3 is a partial view, in lateral elevation, of the device of FIG. 1 in a folded-away position;
FIG. 4 is a front view, in cross-section, illustrating a detail of the device for folding away the props;
FIGS. 5a, 5b, 5c and 6 illustrate an alternative embodiment.
According to the essential characteristic of the invention, a device is provided which is rigidly attached to a container able to be incorporated into the volume of the latter and into the original structure of a standard container, for example a 20-foot container constructed according to the ISO standard, the props also remaining rigidly attached to the container in the folded-away position without exceeding the authorised overall size for transporting by road.
Reference will firstly be made to FIG. 4 for understanding the structure of the container.
The latter comprises a so-called container body (1), with a floor (2) and resting on lateral structural members (3, 4) which open outwards laterally and are braced by I-beams (5) rigidly attached to the said structural members.
It will be noted that the structural members extend as far as the base (6) of the container and of its seat, as shown by the sections (3a, 4a).
According to the invention, a sheath (7) in which the support arms (8, 9) of the props can slide, is arranged from one structural member to the other. While they slide, these support arms are guided and held in the completely opened-out position, so as to prevent them leaving the sheath (7), by a rod (10) fitted at one of its ends with a lockwasher (11) welded to a prop (12) and at its other end with a washer (13) which can slide with respect to the other prop (14). The lockwasher (11) will be welded onto the outer face of the support arm (8). The support arm (9) comprises, at its inner end, a prop-extending lockwasher (15) and, at its outer end, a welded stopper (16).
The ends of each sheath corresponding to a pair of props will be welded onto the structural members (3, 4).
Reference will now be made to FIG. 1, where, for example, the prop (15) has been represented with the corresponding structural member (3, 3a) and the container 1.
This figure also shows the cylindrical sheath (7) and the support arm (8).
The prop (15) comprises a bearing arm (16) comprising a removable pin (17) swivelling on a fork joint (18) rigidly attached to the said bearing arm.
A strut (19), hinged to the corresponding structural member at a point (20), th
