Claim:
A lattice support structure having lattice bars pivotally connected to one another, wherein the lattice support structure has lattice bars ( 10 ) extending in the longitudinal direction of the lattice support structure as well as lattice bars ( 20 , 30 ) connecting them, with the connecting lattice bars ( 20 , 30 ) being connected directly or indirectly to the lattice bars ( 10 ) extending in the longitudinal direction such that the spacing oldie lattice bars ( 10 ) extending in the longitudinal direction of the lattice support structure can be decreased on the inward folding oldie lattice support structure and can be increased on the folding apart of the lattice support structure, wherein first connecting lattice bars ( 20 ) are provided which extend in a first direction toward the lattice bars ( 10 ) extending in the longitudinal direction in the folded apart state of the lattice support structure and which comprise two or more parts directly or indirectly pivotally connected to one another; and in that second connecting lattice bars ( 30 ) are provided which extend obliquely to the lattice bars ( 10 ) extending in the longitudinal direction in the folded apart state of the lattice support structure, with two lattice bars ( 10 ) extending in the longitudinal direction being connected to one another by at least one first connecting lattice bar ( 20 ) and at least one second connecting lattice bar ( 30 ), and wherein the second connecting lattice bars ( 30 ) are made in two parts or in multiple parts, with a first part ( 32 ) being connected to the second part ( 34 ) by means of a joint ( 33 ) in that the two parts ( 32 , 34 ) are pivotable relative to one another, with the second part ( 34 ) being arranged such that it is pivotably connected to the lattice bar ( 10 ) extending in the longitudinal direction, and wherein connection struts ( 40 ) are provided which comprise two parts or more than two parts ( 41 , 42 ) pivotable relative to one another and which connect a second connecting lattice bar ( 30 ) to a first connecting lattice bar ( 20 ) and are pivotally connected to both lattice bars ( 20 , 30 ), wherein the joint ( 33 ) by which the first part ( 32 ) of a second connecting lattice bar ( 30 ) is connected to the second part ( 34 ) is made such that only a pivot movement away from the adjacent lattice bar ( 10 ) extending in the longitudinal direction is possible for an inward folding of the lattice support structure.
