FIELD: construction.
SUBSTANCE: limiter of rotation angle of leaf relates to locking bars and other lock devices for leaves, mainly for doors or windows of buildings, in particular to devices limiting opening of doors and windows and locking them in opened position using the movable elements installed on the frame and leaf, and engaged and disengaged to ensure further opening in case when the leaf is closed only. The limiter contains hingedly secured gusset with slot, and rigidly secured guide casing with transverse hole, and connected to its ends longitudinal initial and fixing holes for handle movement along them, the handle is rigidly secured on the lock bar with end hitch, located with possibility of longitudinal and revolving movement in the guide casing. On the gusset side looking on the guide casing, as minimum one longitudinal shoulder is made with height not exceeding maximum possible path of the lock bar handle movement in the locking hole. On the gusset with possibility of longitudinal movement C-shape slider is installed, its ends envelope the gusset from the side looking on the guide casing. In C-shape slider a hole is made with possibility of the hitch passing though it after passing though longitudinal slot in the gusset, and with possibility of further engagement with C-shape slider after its rotation.
EFFECT: improved design.
