FIELD: construction.
SUBSTANCE: device to limit angle of fold rotation relates to bolts and other locking devices for folds, preferably for doors or windows of buildings, in particular, to devices for limitation of doors and folds opening and for their fixation in the open position with the help of movable elements located on the frame and fold, engaged and disengaged for provision of the next opening only in case, if the fold is closed. The device comprises a hingedly fixed pad with a longitudinal slot having an expanded end facing the hinged joint, and a rigidly fixed guide body with a longitudinal well, made as capable of bolt handle movement along it with a hook at the end. The hook is made as capable of passage via the expanded end of the longitudinal slot and subsequent fixation at least at one longitudinal edge of the longitudinal slot in the pad as the fold is rotated. A C-shaped slider is put on the pad as capable of longitudinal movement, ends of which cover the pad at the side facing the guide body. In the C-shaped slider there is a hole with the possibility of hook passage through it after passage through the expanded end of the longitudinal slot in the pad.
EFFECT: increased operational reliability.
