Abstract: A connecting arrangement for connecting two parts (1, 5) by way of two connected sockets (2, 4), wherein parts and sockets have rotationally symmetrical engagement regions, not exceeding 180°, about engagement axes (11, 15 or 12, 14), which engagement regions are complementary between one part and one socket each, wherein one socket is rotated into one part each, and the complementary engagement regions hold the part on its socket so as to be pivotable about the respective aligned engagement axes and so as to withstand tensions in the direction of a zenith axis of the parts (10 or 16), and in that, after the parts and socket pairs are rotated into engagement and positioned with respect to each other, the sockets (2, 4) are connected to each other, the connection being rotationally and tensionally stiff with respect to the direction of the zenith axes.

Abstract: A device for connecting two construction components (10, 12) that are have engagement structures (16) on two connection surfaces (14) that are facing each other, in which the components (10, 12) have at least two pairs of oppositely disposed circular arc-shaped engagement structures (16) each of which extends over an angle of not more than 180° and has at least one open end, the engagement structures being arranged such that the center of the circular arc of the engagement structure of one pair is different from the center of the circular arc of the engagement structure of each other pair, and at least two connectors (22) are provided, each of which has engagement structures (24) complementary to the engagement structures (16) of one pair and adapted to be inserted in a rotary movement into the two engagement structures (16) from the open end.

Abstract: A bearing arrangement having at least two parts (10, 12) rotatable relative to one another, in which one (10) of the parts has at least one annular groove (14) concentric with the axis of rotation (A), and the other part (12) has a tongue (16) that is complementary to the groove (14) and engaged therein, and in that each of the parts (10, 12) is divided into at least two sectors (10a; 12a) along separating faces that pass through the groove (14) and the tongue (16), the tongue (16) extending over all sectors (12a, 12b) of the corresponding part (12).

Abstract: A bar-type supporting framework having nodes (10, 12, 14) and bars (16, 18, 20) held between the nodes in a form-fitting manner at least in the direction transverse to the longitudinal direction of the bar by engagement elements (34), such that at least one bar (20) and/or at least two nodes (14) connected by a bar are formed of a plurality of parts (24, 26; 30, 32) that are form-fittingly held together by relative rotation of the engagement elements (34) of the bars and the nodes about an axis extending in the longitudinal direction of the bars.
