Definitions

  • the invention relates to a device for tensioning at least one web of material, having a tensioning device with a profile assembly extending along a longitudinal axis and a movement member movably mounted in the profile assembly, according to the preamble of claim 1.
  • the invention also relates to an architectural element, in particular a ceiling element or a wall element.
  • the invention also relates to a method for tensioning at least one fabric web.
  • Stretch ceilings or ceiling elements made of fabrics, foils or other textile fabrics are widespread as architectural elements in modern interior design. Wall elements of a similar construction are also known. Such elements are used as heating or cooling ceilings, backlit luminous ceilings and acoustic absorbers as well as pure design elements or as room dividers.
  • foils that shrink under the influence of heat. In this case, however, an inspection of the covering is of course no longer possible.
  • the choice of material and the design options are also correspondingly limited in this process.
  • the panels of fabric are fastened by staples or screw connectors at specified intervals, and in this way gradually after excited. This process can be very time-consuming, especially when individual parts of the structure are difficult to access or when the element covers a large area.
  • an overhaul is usually not possible without a complete replacement of the fabric covering, or at least not without a great deal of effort.
  • CN 205421674 U proposed to arrange a covered with a fabric frame within a main frame pivotable via a joint.
  • the construction is comparatively complex and expensive.
  • this is suitable in the CN 205421674 U proposed system also only for smaller ceiling elements.
  • the object of the present invention is to provide a device for tensioning at least one fabric web, with which the assembly of the fabric webs is simplified, with preferably good inspection options or good dismantling of the fabric webs.
  • the present invention is also based on the object of providing an architectural element with at least one fabric web, in which the assembly of the fabric webs is simplified, with preferably good inspection options or good dismantling of the fabric webs.
  • the object is achieved for the device with the features listed in claim 1.
  • the object is solved by the features of claim 9 with regard to the architectural element and by the features of claim 12 with regard to the method.
  • a device for tensioning at least one web of material having a tensioning device with a profile assembly extending along a longitudinal axis and a movement member movably mounted in the profile assembly.

  • the moving member is preferably a single component, but in principle it can also be a plurality of components which are arranged in alignment with one another in the profile assembly.
  • the moving member can preferably be made of a metal or at least have a metal.
  • the moving element can be made of any desired material, for example also of a plastic.
  • the at least one web of material is preferably not to be understood as part of the device.

  • the moving element in the profile assembly can be moved from a pre-assembly position to a final assembly position in order to mechanically tension the at least one fabric web transversely or orthogonally to the longitudinal axis of the profile assembly during movement into the final assembly position.
  • the proposed moveable mounting of the moving element within the profile assembly provides a convenient way of tensioning at least one fabric web by moving the profile assembly from the pre-assembly position, in which the fabric web is not yet (completely) tensioned, to the final assembly position, in which the length of fabric is (fully) stretched.

  • a hose-like lifting bag can be advantageous for enabling a uniform movement of the moving element from the pre-assembly position into the final assembly position and enable gentle tensioning of the fabric web(s).
  • the tensioning device has a locking device in order to lock the moving element in the final assembly position in order to block a movement of the moving element back into the pre-assembly position.
  • a locking device can be particularly advantageous because in this case the force that has contributed to the tensioning of the fabric web, i.e. to move the moving member from the pre-assembly position to the final assembly position, no longer needs to be maintained.

  • the tensioning device 14 preferably has a locking device 24 in order to lock the moving element 15 in the final assembly position E, ie in order to block a movement of the moving element 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 safety device 26 .
  • a secondary safety device 26 can be, for example, in the Figures 1 and 2 Act indicated compression spring, which acts on the locking element 25 with a force in the direction of the locking position.
  • one 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 moving element 15 is in the final assembly position E.
  • the compression spring or the secondary fuse 26 on the one hand fulfills the function of an actuating element and on the other hand the function of a secondary fuse 26.
  • An alternative or additional, optional secondary fuse 26 is in figure 2 indicated by dashed lines as a projection, behind which the locking element 25 is able to engage, for example when the moving member 15 is briefly spanned during assembly and later relaxed again somewhat.
  • the locking device 24 has a second actuating device 27 in order to move the locking element from the locking position into the unlocking position.
  • the second actuating device 27 has at least one secondary lifting bag 28 which is arranged and oriented 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 bag 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 bag 28 with the fluid from a device 23 for supplying and/or removing the fluid or to pump out the fluid (preferably by means of a the same device 23, which is also provided for use with the primary lifting bag 20, but optionally also a further device 23).
  • a second embodiment of the device 6 is in figure 4 implied.
  • the device 6 for tensioning the fabric webs 4, 5 is shown as an example.
  • the fabric panels 4, 5 themselves and the optional frame assembly 3 are not shown.
  • the moving member 15 is displaceably mounted in a linear guide 29 of the profile assembly 2 extending transversely to the longitudinal axis L of the profile assembly 2 for the 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 in turn provided, which in the embodiment of figure 2 is also linearly displaceable and is able to 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. Finally, lifting the locking element 25 out of the latching recess 30 of the moving member 15 also allows the moving member 15 to be moved back into the pre-assembly position V in order to undo the tensioning of the fabric webs 4, 5 again.
  • the Figures 5 and 6 show a third embodiment of a device 6 according to the invention for tensioning two fabric webs 4, 5 in the relaxed or open state ( figure 5 ) and in the clamped or closed state ( figure 6 ) each in a side view.
  • the Figures 7 and 8 show an exemplary assembly sequence for assembling the primary lift bag 20 in the moving member 15 ( figure 7 ) and for assembly of the secondary lifting bag 28 in the locking element 25 as well as the locking element 25 in the profile assembly 2 ( figure 8 ).
  • the panels 4, 5 and their fasteners 13 are in the Figures 5 and 6 not shown.
  • the third embodiment largely corresponds to the first embodiment of FIG Figures 1 to 3 , which is why the differences are mainly discussed below.
  • an optimized respective position and mounting or attachment option for the lifting bags 20, 28 is shown in particular.
  • An advantageous, but only to be understood as an example assembly sequence for mounting the Lifting bags 20, 28 is in the Figures 7 and 8 shown (each as assembly step a).
  • the lifting bags 20, 28 can basically be designed like a tube (cf. figure 7 ), it being possible for a pin-shaped body 31 to be passed through the cavity of the lifting bag 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 bag 20, 28 in a corresponding receptacle in the moving 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 lift bag 28 is in its inflated condition and in figure 6 the primary lift bag 20 is shown in its inflated condition.
  • the locking element 25 also has a stop 32 for the moving member 15, on which the moving member 15 is in its open state or in the pre-assembly position (cf. figure 5 ) can advantageously support.
  • 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 coil spring or torsion spring may be particularly advantageous for providing sufficient force to the locking member 25 to safely move into the locked position and remain there until intended release occurs (particularly by actuation of the secondary lifting bag 28).
