FIELD: construction.
SUBSTANCE: flap turning angle limiter with the right slider and the reference hole in the left cover relates to bolts and other locking devices for the flaps, in particular to devices for limiting the opening of doors and windows in buildings and for fixing them in the open position by means of the movable elements located on a frame and a flap, to be hitched and unhitched. The limiter comprises the hinged plate with a longitudinal groove, the bolt with a handle and a hitch, the guiding housing, which accommodates the bolt and in which a winding slot is made, consisting of the transverse bore and the initial bore and the fixing bore connected with its ends, made longitudinal and arranged in opposite directions from the transverse bore with the possibility of moving the bolt handle along them. Longitudinal projections are made on the plate side facing the guiding housing. The right slider is put on the plate. A rack ratchet mechanism is arranged on the plate, comprising a rack made in one of the groove longitudinal edges, and an arresting device equipped with an adjustment handle. The arresting device is located in the longitudinal groove between the right slider and the left cover placed on the plate overlapping with the both groove longitudinal edges and connected to the right slider with the possibility of moving together with the arresting device along the longitudinal groove. In the left cover the reference hole is made, with the possibility of passing the hitch sequentially through it and through the plate longitudinal groove, as well as the auxiliary hole through which the adjustment handle is moved out. The arresting device may be spring-loaded, or made springy of a resilient material.
EFFECT: provision of further opening only in case the flap is closed.
