FIELD: construction.
SUBSTANCE: device for limiting the flap turning angle with the 0-shaped slider lug and the 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 case 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. On the plate the 0-shaped slider is arranged and the rack ratchet mechanism is made, comprising a rack in one of the longitudinal groove edges and the arresting device equipped with the adjustment handle, arranged within the 0-shaped slider and connected thereto with possibility of squeezing out of the toothed recess and movement in the groove between one of the 0-shaped slider walls and the cover placed on the plate overlapping with the both longitudinal groove edges and connected to the 0-shaped slider with the possibility of moving together with it and with the arresting device along the groove. The 0-shaped slider is provided with at least one lug with the possibility for the hitch to pass through it, and the auxiliary opening is made in it or in the cover, through which the adjustment handle is moved out. The arresting device may be spring-loaded towards the rack.
EFFECT: provision of further opening only in case the flap is closed.
