DESCRIPTION:
BRIEF SUMMARY
The present invention relates to a back-pack frame for carrying loads, having longitudinal beams, and cross beams, carrying straps and load-securing elements, and having coupling elements that make it possible to arrange two such back-pack frames end-to-end so as to form a platform that can be either carried or pulled along the ground, four longitudinal beams being provided in a spatial arrangement, and one pair of longitudinal beams defining a sliding plane.
A back-pack frame of this kind is described in DE-OS 23 39 199. This back-pack frame is provided with various coupling elements, so that other possible applications result, if at least two of the frames of this kind are coupled together, such applications being, for example, stretchers, sleds, single or multi-wheeled vehicles, etc.
The present invention aims to provide a back-pack frame that not only premits additional possible applications by the combination of two back-pack frames, but which is also better suited for any application, when used as a back-pack frame and can be doubled for any purpose. In particular, these improvements apply to the manner in which loads to be transported are secured to the back-pack frame and to the transport characteristics, so that the apparatus is similar to a rucksack, a stretcher or litter, and a sled.
According to the present invention, this problem is solved in that the four longitudinal beams are arranged so as to correspond approximately to the edges of a prism and form a carrier-side pair and load-side pair, the two load-side longitudinal beams defining the sliding plane that on the two narrow sides of the back-pack frame that contain in each instance a longitudinal beam of both pairs there is at least one holding element for a removable shackle that extends beyond the load-side longitudinal beam, and that on each carrier-side longitudinal beam above the lowest holding element there is at least one side-wall element that is of flexible material, and each side-wall element of the one carrier-side longitudinal beam being connectable with a side-wall element of the other carrier-side longitudinal beam so as to form a carrier - as well as a load-side covering.
This provides for a back-pack carrier frame in which the spatial arrangement of the four longitudinal beams forms a hollow space that accommodates the normal support-belt tensioning and attachment, but does not accommodate the load. This means that the width of the narrow sides is small, which results in great user comfort. When used for back-packing, the load area lies outside the sliding plane and is of variable volume. The shackles are secured to the narrow sides, which is to say to the sides, since the configuration of the holding elements can be in any form that is desired at this location. A plurality of holding elements can be arranged one above the other, which means that the shackles can be adjusted for height, and also means that it is possible to provide two or more shackles above each other. The sliding plane that is required when the apparatus is used as a sled is not interrupted, so that the sled has very good sliding characteristics. In this arrangement the simple back-pack frame can be used as a small individual sled, and two back-pack frames arranged one behind the other to be mirror images of each other can be used as a bigger transport- or rescue sled. When the back-pack frame is used as a rucksack, the load can be fixed at the load-side, when it is used as a sled or stretcher, the load or the person to be transported can be fixed at the carrier-side by means of the flexible side-wall elements, in this instance, too, a load area of variable volume lying substantially outside the hollow space formed by the longitudinal beams. Since preferably a plurality of holding elements are provided, which may not of course be covered by the side-wall elements, it is preferred that several side-wall elements be arranged one above the other on each longitudinal beam on the carrier-side. This results in the advantage that the length of the covering of ea
