Modular system

A modular system (10, 81, 103, 109, 113, 118) for structuring or designing spaces or surfaces, comprising a component assembly, comprising at least two modular elements (12, 13, 65, 71, 82, 83, 86, 93, 97, 98, 99, 100, 101, 104, 111, 115, 120, 122, 127, 136, 141, 142) and at least two connecting elements (14, 15, 16, 37, 38, 53, 54, 59, 60, 67, 68, 75, 76, 77, 96, 105, 134, 140, 148, 154), said modular element being designed as a box-shaped body (22, 87), whose base (17, 84, 125, 131) comprises at least three corners (18, 94, 146), each corner forming a connecting structure (19, 128) for connecting the modular element to the connecting elements, the connecting structure having an arc-shaped contour (24, 144) of the corner in conjunction with a void (23, 129, 137, 152) adjacent to the contour, each connecting element comprising a pin (29, 41, 80, 107, 138, 151, 155) for the connecting structures to be connected, said pin being congruent with the void for being interlockingly inserted into the void, each said connecting element forming a positioning device for positioning the connecting element at the modular element, said positioning device comprising an axis (30, 42, 79, 106, 149), said axis being congruent with the contour for being arranged at said contour, said at least two connecting elements arranged opposite one another at the connecting structure in such a manner that the axes (30, 42, 79, 106) and pins (29, 41, 80, 107, 138, 151, 155) align.
