Lattice support structure

Abstract

The present invention relates to a lattice support structure having longitudinally extending supports which are connected to one another by obliquely extending struts and are also connected to one another in the state of the lattice support structure ready for operation by transversely extending struts provided with a joint, with the struts being pivotably connected to two respective preferably adjacent supports, with at least one connection strut being provided which connects two supports to one another which are not adjacent to one another and which are preferably disposed opposite one another, and with the at least one connection strut and/or at least one component of the lattice support structure connected thereto having fastening means or being connected or connectable thereto, with the fastening means being made such that they prevent a folding together of the lattice support structure in at least one position.
