The invention relates to a pivot locking device of two bearing elements (102, 103) oriented towards a common axis, in which one or both bearing elements (102, 103) are pivotable about a common pivot axis (22), with a first bearing element (102), which comprises a perforation (104), with a second bearing element (103), which comprises a perforation (106), wherein the first and second bearing elements (102, 103) are oriented in alignment to one another with the perforations (104, 106), with a chamber (124) provided on the first bearing element (102), which chamber comprises a circulatory path for circulatory elements (129) and is open to the second bearing element (103) and, by a connecting surface (118) facing to the chamber (124), is closed on the second bearing element (103), with a plurality of circulatory elements (129) arranged in the chamber (124), with an catch (121) arrangeable on the second bearing element (103), which catch engages into the circulating chamber (124) and is positioned between circulatory elements (129) and, in a pivot movement of the second bearing element (103) to the first bearing element (102), displaces the circulatory elements (129) in the chamber (124) along the circulatory path, and with a locking element (107) arranged on the first bearing element (102), which locking element, in an unlocking position (109), unblocks the circulatory path for the circulatory elements (129) in the chamber (124) and, in a locking position (108) of the locking element (107), blocks a displacement movement of the circulatory elements (129) along the circulatory path of the chamber (124).
