FIELD: construction.SUBSTANCE: fold rotation clear space limiter 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 limiter comprises a hingedly fixed pad with a longitudinal slot and a rigidly fixed guide body with a transverse well and an initial well and a fixing well connected to its ends, made longitudinal and located in opposite directions from the transverse well with the possibility of bolt handle movement along them, two longitudinal wells for movement of the handle along them, being rigidly fixed on the bolt with a hook at the end placed as capable of longitudinal and rotary movements in the guide body. On the side of the pad opposite to the guide body there is at least one longitudinal ledge with height not exceeding the maximum possible path of bolt handle movement in the fixing well. A C-shaped slider is put on the pad as capable of longitudinal movement, ends of which cover the pad at the side opposite to the guide body. In the C-shaped slider there is a hole with the possibility of hook passage through it first, and then with the possibility of hook fixation against the longitudinal ledge after its rotation and limited rotation of the fold.EFFECT: increased operational reliability.3 cl, 14 dwg |
