FIELD: construction.
SUBSTANCE: device for limiting the flap turning angle with the reference hole in the left slider and the other reference hole the in the right cover relates to bolts and other locking devices for flaps, mostly for doors and windows in buildings, in particular to devices for limiting the opening angle of doors and flaps and fixing them in the open position by means of movable elements arranged on a frame and a flap, which are hitched and unhitched to allow the further opening only in cases when the flap is closed. The device comprises the hitch and the plate adapted for a hinge joint, with the groove having a flared end facing the hinge joint. The hitch is made movable, with the possibility to move longitudionally and to pass through the flared groove end and to hitch on the longitudinal groove edges when opening the flap. The cover has a rack ratchet mechanism which contains a rack in one of the longitudinal groove edges, with an arresting device equipped with an adjustment handle, arranged with the possibility of squeezing out of the toothed recess and moving in the groove between the right cover and the left slider put on the plate, interconnected so that they can move together with each other and with the arresting device along the groove. In the left slider a reference hole is made, and in the right cover the other reference hole is made with the possibility for the hitch to pass sequentially through the reference hole in the left slider, the flared groove end and the other reference hole in the right cover. The hitch is made at the bolt end placed in the guiding housing. The left slider has an auxiliary opening through which the adjustment handle is moved out. The arresting device can be spring-loaded toward the rack or be made springy of resilient material.
EFFECT: provision of further opening only in case the flap is closed.
