Abstract

A hinge joint for windows, doors, or the like which can especially be provided on the swing out arm of a disengagement device for rotary/tilt wing. An angular intermediate piece 14 is swingably held in a bearing block adapted to be fixed at a blind frame. It is connected with a supporting arm 15 which is swingable by 180.degree. around an articulated axis 19--19 through a pivot pin connection. The supporting arm engages the wing as a holding element and is fixable in position with respect to the angular intermediate piece 14 in two swiveling positions offset by 180.degree.. The end of the supporting arm 15 facing the angular intermediate piece 14 exhibits a fork shape having two parallel fork legs 38 adapted to pass laterally along a bearing eye 28 on the intermediate piece 14 wich encompasses the articulated axis 19--19. A cam or ledge 29 projects radially from the bearing eye forming stop surfaces pointing away from each other against which the fork legs 38 can be braced in each of two rotary positions offset by 180.degree..
