FIELD: mechanical engineering.
SUBSTANCE: disclosed is a wing (100) of the hinge for a hinge joint of the shutter with the frame around the hinge axis (S). The wing includes a longitudinal recess (3), a support sleeve (4), which is located in the longitudinal recess (3) and is made with the possibility of rotation around and a laterally offset pivot axis, which is parallel to the hinge axis (S), (D) by means of an optional pivoting aid (12) and which includes a recess (5) of the support sleeve for receiving the hinge pin, an internal thread (35) provided at least in the end region of the longitudinal recess (3). There is an external thread (8) and a lifting spindle (7, 7`) screwed into the internal thread (35). The lifting spindle has a support side (9) for indirect or direct support of the support sleeve (4) and / or the hinge pin and is made in the form of an optional turning aid (12). There is a key surface (13) for the transmission of torques between the lifting spindle (7, 7`) and the support sleeve (4). There is the counter key surface (14) on the lifting spindle (7, 7`) brought into a kinematic connection with the key surface (13). According to the invention, the key surface (13) is located on at least one recess (21a, 21b, 21c, 21d) made on the circumferential end lateral surface (6), and the counter key surface (14) is located on at least one projection (22a, 22b, 22c, 22d) made in accordance with the recess (21a, 21b, 21c, 21d).
EFFECT: invention makes the functioning of a hinge wing more effective.
