FIELD: construction.
SUBSTANCE: device for limiting the turning angle with the left slider and the reference hole in the right side cover is a type of bolt and other locking tools for flaps, mostly doors and windows in buildings, in particular devoces for limiting the opening angle of doors and flaps and to fix them in the open position with thelp of moveable frame and flap elements, which engage and disengage to allow for further opening only in cases when the flap is closed. The device consists of a hook and a hinge cover with a groove for a hinge joint, with a flared end facing the hinge joint. The hook is longitudinally movable, and can pass through the flared end of the groove and engage the longitudinal edges of the groove when opening the flap. The cover has a pinion ratchet mechanism which contains a rack in one of the longitudinal groove edges, equipped with an adjustment handle arresting device, which can squeeze out toothed recesses and move in the groove between the right cover and the left slider on the cover, which are connected so that they can move parallel with each other and an arresting device along the slot. The right cover has a reference hole which allows the hook to pass through it after passing through the flared end of the groove. The hook is located at the end of the bolt, placed in the guide housing. The left slider has an auxiliary opening for the adjustment handle. The arresting device can be spring loaded toward the rack or be made of resilient springly material.
EFFECT: improved functional reliability.
