23305-1051 A B S T R A C T Foldable composite system consisting of rigid plate-like parts or solid bodies with straight lateral sides, interconnected with endless fastening elements With the foldable composite system consisting of rigid plate-like parts or solid bodies interconnected by endless fast- ening elements, on front and rear surfaces of each plate-like part are provided with grooves divided in two groups and running par- allel with one another within each group. The grooves /5/ belong- ing to the two groups are enclosing an angle /.gamma.,.delta./. Grooves /5/ are sloping under an acute angle /.alpha.,.beta.,.alpha.',.beta.'/ to the lateral sides /a, b, c, d/ of the plate-like parts /A, B etc./. In the grooves /5/ endless elastic fastening elements /1, 2, 3, 4/ are arranged so, as to be independent of the plate-like parts /A, B etc./. The fastening elements span the plate-like parts /A, B etc./ in a symmetrical arrangement and so, that each of endless fastening element /1, 2, 3, 4/ is led into the groove /5/ on the opposite surface of the plate-like part /A, B, etc./ and in such a manner, that in case of the outmost lateral sides the grooves are of different direction, while with the lateral sides forming a line of contact, the grooves are running in the same direction, accordingly, on the surface each of a plate-like part /A, B, etc./ each only parallel fastening elements /1, 2, 3, 4/are to be found, while the fastening elements /1, 2, 3, 4/ are passing the lines of contact of the plate-like parts /A, B, etc./ each to be connected at least three times. 23305-1051 On one or both surface of the parts to be connected markings, numbers, letters, text- or pattern parts are to be found, for differentiating and determining their position, res- pectively. /Fig. 1/
