FIELD: construction.
SUBSTANCE: device for limiting the flap turning angle with the reference hole in the right slider and the hitch on the left 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 the reference hole in th right slider, as well as with the possibility to hitch on the longitudinal groove edges when opening the flap. The right slider is put on the plate on which the rack ratchet mechanism is made, which contains the rack in one of the groove longitudinal edges, and 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 left cover and the right slider, interconnected so that they can move together with each other and with the arresting device along the groove. The hitch is made on the left cover with the possibility of hitching on the bracket rigidly attached to the guiding housing with the bolt, on which the hitch is made. In the left cover the auxiliary opening is made, 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: device improvement.
