Definitions

  • the present invention relates to a lattice support factory, which is adjustable between a folded and a folded state, wherein the lattice support structure has longitudinal supports, wherein the distance of at least two of the longitudinal supports to each other in the folded state of the lattice support structure is less than in the unfolded state of the Lattice support work and wherein at least two of the longitudinal supports in the unfolded state of the lattice support structure are connected by struts.
  • lattice structures are known from the prior art, which have longitudinal supports which, in the unfolded state of the lattice support structure, are connected to one another by struts which, for example, can run obliquely.
  • the arrangement of the struts is achieved such that the distance between the extending in the longitudinal direction of the lattice support columns is reduced and increased, so that the lattice support structure can be folded and unfolded.
  • the present invention has the object of developing a lattice support structure of the type mentioned in such a way that this is a comparison has a simple structure and yet allows easy folding and unfolding.
  • At least one of the longitudinal supports at least one rail is arranged, and that the struts have at their facing to the rail portion means by which the struts run on or in the rail when the distance from longitudinally Supports change each other.
  • the present invention is therefore based on the object to achieve a relative movement between the longitudinal supports and the struts in that the struts run during folding or when unfolding the lattice structure on rails that are arranged directly or indirectly on the longitudinal supports.
  • the design of the rails themselves is arbitrary, as long as it is ensured that the struts can be moved along the rails. It is conceivable, for example, that the rail or the struts have rollers or rollers on which rolls the other part. It is also conceivable, for example, a sliding movement or the like.
  • the struts may be in communication with the rails such that, while movable relative to the rails, they can not be lifted off the rails. It is conceivable, for example, that the struts engage behind the rails at least partially, so that they can be reliably guided on the rail.
  • the design of the rail itself is largely arbitrary. It is conceivable to carry out the rail with a smooth running surface or even with a groove in the one Part of the strut is running.

  • struts may be the same struts running on rails in another area, for example in the other end area, as stated above. It is therefore conceivable, for example, that a region of the struts is pivotable, but not arranged on rails movable on the longitudinally extending supports and another area of the struts on rails is movable, as stated above in more detail.
  • struts are provided which connect two adjacent or two non-adjacent, preferably two diagonally opposite longitudinal supports together.
  • these further struts have one or more joints so that they can be moved into their folded, preferably rectilinear position during folding of the lattice support structure into its folded-in position and during unfolding of the lattice support structure.

Once this is the case, it may be locked by appropriate means if necessary. As stated, it is also conceivable that the lattice structure itself has one or more actuators for folding and / or unfolding.
  • actuators can be designed so that they act, for example, on the struts or strut sections, which are in communication with the rail (s) and effect the desired relative movement between rail and strut.
