DRIVE HANDLE Russian patent published in 2016 - IPC E05B3/04 

FIELD: construction.

SUBSTANCE: disclosed is a drive handle for folding structural elements, such as windows, doors and similar. Drive handle includes handle part (10), gripping element (20), seat bushing (30), which can be connected or is connected without possibility of rotation with handle part (10) and has nested hole (31), through which seat bushing (30) in direction (R) of input is inserted gripping element (20), wherein gripping element (20) can be connected with seat bushing (30) without possibility of rotation. Drive handle also includes clamping device, through which gripping element (20) is clamped in seat bushing (30) so as to prevent extraction of gripping element (20) opposite to direction (R) of input, and which includes first clamping frame (33a) and second clamping frame (33b), having on recess (34a, 34b) for fitting gripping element (20) and brought into contact with gripping element (20) clamping surface (35a, 35b). First clamping frame (33a) and second clamping frame (33b) are located opposite each other so that two recesses (34a, 34b) together form a through hole (38) for gripping element (20). First clamping frame (33a) and second clamping frame (33b) can turn in opposite directions of rotation.

EFFECT: when gripping element (20) in through hole (38) first clamping frame (33a) and second clamping frame (33b) from initial position, in which they together form first angle (α1), turn to a position whereat they make second angle (α2), smaller than first angle (α1), wherein clamping frame (33a, 33b) by means of one common spring (40) are loaded with a force in direction of their initial position and as a result of contact clamping surfaces (35a, 35b) with gripping element (20) act on gripping element (20) with retaining force.
