  • a fluid connection 21 of the primary lifting bag 20 can be connected to a supply line 22 for the fluid (gas and/or liquid).
  • the device 6 can also have a device 23 for supplying and/or removing the fluid, for example an electrically operable pump.
  • a corresponding device 23 for supplying and/or discharging the fluid can also be provided on site.
  • the clamping device 14 has a locking device 24 in order to lock the movement member 15 in the final assembly position E, i.e To block movement of the movement member 15 back into the pre-assembly position V, preferably in a form-fitting manner.
  • the locking device 24 has a locking element 25.
  • a pivotable locking element 25 is provided.
  • the locking element 25 is between an unlocking position (cf. Figure 1 or. Figure 5 ) and a locking position (cf. Figure 2 or. Figure 6 ) movable.
  • the locking device 24 can also have a secondary lock 26.
  • This can be, for example, one in the Figures 1 and 2 indicated compression spring, which applies a force to the locking element 25 in the direction of the locking position.
  • a tension spring, a torsion spring or spiral spring cf. Figures 5, 6 and 8
  • another force-generating unit can be provided, but in particular a spring mechanism.
  • the compression spring, tension spring, torsion spring, spiral spring or other unit can in principle also serve as an actuating element in order to automatically lock the locking device 24 or the locking element 25 as soon as the movement member 15 is in the final assembly position E.
  • the compression spring or the secondary fuse 26 fulfills the function of an actuating element on the one hand and the function of a secondary fuse 26 on the other hand.
  • FIG. 2 An alternative or additional, optional secondary fuse 26 is included Figure 2 indicated by dashed lines as a projection behind which the locking element 25 can snap into place, for example if the movement member 15 is briefly over-tightened during assembly and later relaxed slightly again.
  • the locking device 24 has a second actuation device 27 in order to move the locking element from the locking position to the unlocking position.
  • the second actuation device 27 has at least one secondary lifting cushion 28, which is arranged and aligned in the profile assembly 2 in such a way that its pneumatically or hydraulically induced expansion causes the movement of the locking element 25 from the locking position to the unlocking position.
  • the secondary lifting cushion 28 can also have a fluid connection 21 in order to connect a supply line 22, not shown, in order to supply the secondary lifting cushion 28 with the fluid starting from a device 23 for supplying and/or discharging the fluid or in order to pump out the fluid (preferably by means of the same device 23, which is also intended for use with the primary lifting bag 20, but possibly also a further device 23).
  • a second embodiment of the device 6 is in Figure 4 indicated.
  • Only the device 6 for tensioning the fabric panels 4, 5 is shown as an example.
  • the fabric panels 4, 5 themselves and the optional frame assembly 3 are not shown.
  • the movement member 15 is slidably mounted in a linear guide 29 of the profile assembly 2 which extends transversely to the longitudinal axis L of the profile assembly 2 for movement between the pre-assembly position V and the final assembly position E.
  • at least one primary lifting bag 20 can cause the movement.
  • a locking element 25 is again provided, which in the exemplary embodiment Figure 2 is also linearly displaceable and can penetrate into a locking recess 30 of the moving member 15 when the final assembly position E of the moving member 15 is reached due to gravity and/or a spring device (not shown). Lifting the locking element 25 out of the locking recess 30 of the moving member 15 ultimately enables the moving member 15 to move back into the pre-assembly position V in order to reverse the tensioning of the fabric panels 4, 5.
  • the Figures 5 and 6 show a third exemplary embodiment of a device 6 according to the invention for tensioning two fabric panels 4, 5 in the relaxed or opened state ( Figure 5 ) and in the tensioned or closed state ( Figure 6 ) each in a side view.
  • the Figures 7 and 8 show an exemplary assembly sequence for assembling the primary lifting bag 20 in the moving member 15 ( Figure 7 ) and for mounting the secondary lifting cushion 28 in the locking element 25 and the locking element 25 in the profile assembly 2 ( Figure 8 ).
  • the fabric panels 4, 5 and their fastening elements 13 are in the Figures 5 and 6 not shown.
  • the third exemplary embodiment largely corresponds to the first exemplary embodiment Figures 1 to 3 , which is why the differences are essentially discussed below.
  • FIG. 7 and 8 An advantageous assembly sequence for assembling the lifting cushions 20, 28, which is only to be understood as an example, is shown in FIG Figures 7 and 8 shown (each as assembly step a).
  • the lifting cushions 20, 28 can basically be designed like a hose (cf. Figure 7 ), whereby a pin-shaped body 31 can be passed through the cavity of the lifting cushion 20, 28, which is later to be filled with air or another fluid.
  • the pin-like body 31 can then be fixed together with the lifting cushion 20, 28 in a corresponding receptacle in the movement member 15 or in the locking element 25 (assembly steps b/c in Figure 7 or assembly steps a/b in Figure 8 ).
  • the secondary lifting bag 28 is in its inflated state and in Figure 6 the primary lifting bag 20 is shown in its inflated state.
  • the locking element 25 also has a stop 32 for the moving member 15, on which the moving member 15 is located in its open state or in the pre-assembly position (cf. Figure 5 ) can be advantageously supported.
  • a stop 32 is only optional and not absolutely necessary.
  • the secondary fuse is designed as a spiral spring (see in particular the assembly example in Figure 8 ).
  • a spiral spring or torsion spring can be particularly advantageous for applying sufficient force to the locking element 25 to move safely into the locking position and to remain there until an intended release occurs (in particular by actuating the secondary lifting cushion 28).
