There are, ζ. Ii. for tents, roofing or silting parts have been proposed which consist of an inflatable surrounded by a shell Air hose. TMe known designs of such struts have the disadvantage that their Buckling strength is low.

According to the invention, a strut or yrstiffening part, which is ordered from an inflatable air tube surrounded by an I lle, is designed in such a way that sheet-like reinforcements made of a firm, elastic, flexible material, ■ / .. II. are provided. When the air hose is inflated, these deposits take the form of a semicircular groove with a relatively high section modulus. With the arrangement of these reinforcements, a surprisingly high buckling strength of the strut * or stiffening part is achieved with simple means. Another advantage of this design is that when the air hose is deflated, the reinforcing inserts take on their flat shape due to their elasticity and therefore adapt to the shape of the deflated hose.

According to an expedient embodiment of the invention, the sheet-shaped reinforcements /. wipe the two layers of a double-walled garbage inserted. 1) ic reinforcements can, however can also be produced in such a way that the filler material is impregnated with a plastic compound will.

In the drawing the subject of the earth is shown. It shows

Fig. Ι a strut in the finished state in view,

l'ig. 2 shows a section through the strut according to 11 11 in FIG.

In the figures, the two layers of the double-walled midie are denoted by ι and i ', the two elastic reinforcement inserts provided according to the invention are denoted by 2 and 2 ″, the air hose with 3 ″ ^{I1 (} l its valve denoted by 4.

I) The garbage 1 is most easily produced by sewing in the fabric of the tent or the object to which the strut is attached. This gives the possibility of giving the stiffening element the shape that corresponds to the intended use. The sheet-shaped reinforcements 2 and 2 _U can easily be cut to the desired shape. The air hose 3 adapts to this shape easily. The fabric forming the cover has an excess edge 1 ″ which, depending on the intended use of the gel smoke article, is connected to it by seams, buttons or in a similar manner.

A strut or stiffening part according to the invention can be used for folding chairs, camp beds, Folding boats, tents and similar objects of use can be used. However, it can also, for. Ti. for suitcases, for packaging material instead of boxes, for lifeboats, as a stick for garden umbrellas, for folding garages and emergency walkways, with the appropriate arrangement also for parachutes and even find use for gliders. In the latter case it is then possible that by one Parachutist using a folded glider after jumping using compressed Air is brought to unfold and thereby a target landing is made possible.
