• pressure member and tension member are connected at the ends of the carrier in a node, wherein the nodes can simultaneously form the support points for the carrier.
• An advantage of such carriers is that they have low mass compared to their stiffness (load capacity). In addition, they are due to the low mass basically easy to transport, even more so because the inflatable body folded together occupies little volume.
• the disadvantage is that in the described construction of a pneumatic carrier load can basically be taken only in a predetermined direction; Moreover, depending on the training of the blowable base body restrictions in the guidance of the tension member or in the combination of the beams to a composite such as a roof, a wall, a bridge, etc.

• the tension member 4 is preferably formed as a rope. Pressure member 3 and tension member 4 are held in other words by the main body 2 at a distance.
• Compression member 3 and tension member 4 are connected to each other in nodes 7, 7 ', which are arranged at the ends of the carrier 1.
• the pressure member 3 is subjected to pressure and the tension member 4 to train, wherein the pressure member 3 is held by the base body 4 in position and supported against buckling, and wherein the tension member is also held by the body 2 in position.

• the support 1 can be completely folded up without having to be disassembled, and on the other hand, it can also be packaged after disassembly, e.g. in that the main body is rolled up around the folded-together pressure member.
• Fig. Ib shows the carrier of Fig. Ia seen from the side, which is a section line 11 along partially cut. In the cut-up area is a longitudinal section through the carrier along the line
• a flexible web 12 which passes through the main body 2 from node 7 to node 7 ', is shown (and indicated by the dashed line 14 in the uncut area).
• the web 12 may be made of e.g. consist of textile fabric, as it is used for the training of the body 2, or of another suitable material; it is preferably continuous, but may also be provided according to the stress with reinforcements or recesses.
• the web 12 connects the pressure member 3 with the tension member 4; According to the preferred embodiment shown in the figure, it is connected to the pressure member 3 at the location of its joints 10 and to the tension member 4 substantially without gaps over its entire length.
• the web 12 is also operatively connected to the base body 2, here on the one hand via the pressure member 3 and on the other hand via the tension member 4, which both rest on the base body.
• Rule in the rootstock 2 is also operatively connected to the base body 2, here on the one hand via the pressure member 3 and on the other hand via the tension member 4, which both rest on the base body.

• the cable 17 thus acts as a reinforcement for the web 12, so that the forces acting punctually on the web 12 by the joints 10 can be appropriately introduced into them.
• the train caused by the internal pressure in the web 12 is uniformly introduced into the tension member 4 (or the main body 2); a deformation of the tension member 4, which does not destroy the load bearing behavior of the carrier 1, but which does not destroy it, is prevented by local introduction of the train.
• the person skilled in the art can optimize the contour of the web 12 in this respect and adapt it to the contour of the main body 2 which is under operating pressure and is subject to the control.
• the train caused by the internal pressure in the web 12 focuses on the side of the pressure member 3 in the joints 10, since the web 12 is connected only to these and thus initiates the corresponding forces only in this.
• the joints 10 are thus fixed by the web in its operative position on the base body, so that a collapse of the carrier 1 is prevented by buckling of the pressure member 3 at the location of the joints 10.
• the web 12 does not necessarily have to act on the joint 10 itself for this purpose, but can also engage in the area of a joint 10, for example at the ends of the sections of the pressure element 3 connected to a joint 10
• the web 12 may be connected to the pressure member 3 continuously, as long as it is designed such that in the case of load the forces exerted by the web 12 on the pressure member 3 are concentrated in the region of the joint 10 and not attack uniformly over the entire length of the pressure member 3.
• the forces exerted by the web 12 on the tension member 4 should be introduced into it as uniformly as possible (so that its "natural" contour is not changed in the load case), while the forces exerted on the pressure member
• the carrier 1 can, on the one hand, be readily folded without it having to be disassembled, since the flexible web 12, and also the flexible tension member 4, can adapt to the folded pressure member 3.
• this configuration is self-operational, which keeps the assembly effort small.
• this arrangement is particularly advantageous in asymmetric loading.
• Symmetrical load distribution i. A uniform load distributed uniformly from node 7 to node T results in a symmetrical bending line curved only in one fault. Locking the hinges 10 in accordance with only one pivoting direction (see the description of Figure Ic and, for example, WO 2006/000159) could in itself be sufficient to maintain the stable position of the pressure member 3, i. a buckling of the pressure member 3 corresponding to the bending line at the location of the joints 10 to prevent.
• Joints 10 on the web 12 is also asymmetric load of the carrier 1 possible without a constructive overhead must be driven.
• Fig. Ic shows a longitudinal section through the carrier 1 along the line AA of Figure Ia, with only the web 12 with the pressure member 3 and the tension member 4 (without body 2) are visible. Shown is a moment in which the carrier 1 is folded (or inflated). The two outer joints 10 are pivoted according to the arrow 15 in a pivot direction and the central pivot 10 according to the arrow 16 in the other pivoting direction. As a result, the sections of the pressure member 3 connected by the joints 10 can be created in an optimal manner parallel to each other during folding.
• Fig. 2 shows a further inventive embodiment of a pneumatic carrier 20, in which both the pressure member and the tension member can equally absorb pressure and tensile load.
• a tension / compression member 22 and a tension / compression member 23 instead of the pressure member 3 and the tension member 4 according to the figures Ia to Ic.
• the pressure member and the tension member are formed opposite. This allows load to be picked up both from above (load according to arrow 8) and from below (load according to arrow 9), thus on both sides.
• Pneumatic carriers of this type are known in principle, but not in collapsible training.
• the web 12 is now arranged and designed such that it fixes all hinges 10 of both members 22, 23 in an operable position in the inflated state of the main body.
• the tension / compression member 23 only absorbs tension. But since it is also pressure-resistant, it has compression rod sections connected by the joints 10, which are stiff; Thus, it is sufficient here if the web 12 initiates the forces transmitted through it only in the region of the joints 10; the load capacity of the carrier 1 is not reduced, as would be the case if instead of the tension / compression member 23 a flexible tension member 4 (FIG. 1b) would occur. Conversely, this also applies to a load acting according to arrow 9 from below.
