ABSTRACT:
A coupling mechanism for coupling two elements in a manner providing for transfer of the rotation moment of one element to the other element. The mechanism comprises at least two coupling element (11, 12), each coupling element having a pair of radially outwardly directed spherical pivot portions (11', 12'). The spherical pivot portions of the coupling elements are housed in an intermediate element (8) comprising a continuous inner ring member (10) defining spherical pockets for the pivot portions and an outer ring (9) circumscribing the inner ring. The pivot portions (11', 12') are rotatable at least around their cardioids while being contained in pockets formed in the inner ring of the annular intermediate element (8), such that the one coupling element can swivel in one plane and the other coupling element can swivel in a plane perpendicular to the first relative to the intermediate element (8). At least one of the coupling elements (11, 12) is formed by an essentially solid shaft-like part at one end of which two spherical pivot portions (11', 12' ) have been formed and whose other end is equipped with means for attachment. The inner ring member is made of a flexible material and in one embodiment of the invention consists of a pair of continuous rings located adjacent the outer axial ends of the outer ring (9).
