Definitions

  • the invention relates to components for a deformable line, surface or spatial structure with articulated connections arranged between adjacent components.
  • the invention further relates to articulated connections for such structures.
  • the subject of the invention also includes a linear, planar or spatial structure itself.
  • Flat structures consisting of articulated components, in special cases also linear structures, can be used, inter alia, as floor coverings; Wall hangings, room dividers and suspended ceiling cladding are used as well as for many other purposes in interior design as well as for technical purposes, for example when attaching soil to slopes and embankments and the like.
  • Such mobility enables the surface structure to be adapted to curved or otherwise curved surface shapes of a base or any other predetermined surface shape, for example for special aesthetic effects for architectural or decorative purposes.
  • an expansion of the flat structures mentioned into spatial structures by arranging additional articulated connections and corresponding components that are applied transversely to the plane of a flat structure is also possible.
  • Such spatial structures can be used in particular for interior design purposes with a particular decorative effect, for example as suspended ceiling cladding with suspension elements or with additional vertical surface elements hanging underneath the actual cladding surface.
  • the object of the invention is therefore to create an articulated connection of the type mentioned at the outset, which is distinguished by a simple structure and allows a configuration with a plurality of degrees of freedom of the positional adjustment of adjacent components.
  • the object of the invention is to create components or articulated connections of the type mentioned at the outset or a deformable structure, by means of which deformation - at least transversely to a surface area of the structure - is possible with a comparatively small number of joints.
  • the inventive solution to this problem is characterized by the features specified in claim 1 or 2.
  • the two solution variants are based on the same principle, namely the connection of adjacent components by only a pairing of articulated parts, which enables a quick and comparatively simple assembly of structures of larger dimensions with a correspondingly large number of components.

  • the inventive solution to this problem is characterized by the features specified in claim 16. If necessary, three-dimensional structures can also be assembled with components that have at least one additional joint part.
  • the joint parts of a component can be connected to form a unit by supporting bodies of different shapes, the shape of the supporting body being adapted to the particular application. If the application does not depend on a more or less approximately closed surface formation of the deformable structure, but rather on a mesh, sieve or filter function or on a flexible supporting or reinforcing function, a cross-shaped or star-shaped configuration is recommended of the support body, wherein the joint parts are arranged at the ends of the star or the cross.
  • Such designs are also suitable for hanging or lying, mat-shaped structures which are composed of components of the present type and e.g. can be used as room dividers or wall hangings in interior design and as floor coverings.

The latching connection is thus released and the tab can be removed from the component recess.
  • the direct and robust support of the tab 48a in the lateral direction is also advantageous in the region of the recess opening via further projections 48c of the tab body. This results in a particularly secure support of the tab in the event of bending stress in the direction parallel to the tab plane, and also an aesthetically satisfactory covering of the recess opening.
  • the tab in cross section according to FIG. 49 in the area of the projections 48b and 48c is slightly angled against the tab level, so that the required clearance results in the middle area of the tab.
  • the side edges of the probe 49a can nevertheless engage the spiral spring sections 50b.
  • the flat spring element can in turn be fastened in the component recess by gluing.
  • an attachment by driving in suitable lugs 50c or 50d (the latter possibility indicated by dash-dotted lines in FIG. 48) is also considered.
  • the spiral spring sections 50b are at one, except for their base Narrow side punched free on all sides so that it is deformable for the snap connection.
  • Sawtooth-like holding elements are formed on the side edges of the fastening sections 50c, which ensure secure fastening in the material of the component.
  • the fastening sections can also be embedded in the material of the component by injection.
  • a tab-shaped connecting member 51a with flat heads 51b on both sides is again provided for the support against bending and torsion in component recesses 53a, which run here in a slot-like manner.
  • the bottom of the recesses is rectilinear in the manner shown in FIG. 53, so that the connecting element can be inserted laterally into the recesses of both components without the components having to be spaced apart from one another. This allows assembly and disassembly of individual components within an existing assembly of components, i.e. without dissolving the surface or spatial structure.
  • projections 51c are formed for the engagement of fixed positive locking elements 52b.
  • the bending and torsion neck 51d is cut free against these projections by short slots, so that the deformability of the neck is not impaired.
  • the form-locking elements 52b are formed by apex sections of clip-like or bridge-like members 52a which are driven into both opposite sides of the opening cross section of the component recesses and overlap this cross section with their apices. As a result, the component body is reinforced in the region of the recess against bending open.
  • Bending spring elements 51c which are integrally formed on the body of the connecting element designed as a stamped part, engage behind the apex sections of the elements 52a after the insertion of the connecting element and form an easily releasable latching connection.
