FIELD: construction.
SUBSTANCE: device for limiting the turning angle with the left slider and the reference hole in the left side cover and the right cover is a type of bolt and other locking tools for flaps, mostly doors and windows in buildings, in particular devices 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. This turning angle limiter is comprised of a cover flap with a groove adapted for a hinge joint, and a hook at the end of the bolt allowing it to move longitudinally, passing through the groove of the cover flap, rotate and engage the groove edge over its entire length. Rigidly mounted on the bolt is the handle, the bolt is placed in the housed in the guide body, which includes a winding slot consisting of a transverse hole and longitudinal ends of loop holes located in the opposite direction from the loop hole, allowing the bolt handle to move along it. The side of the cover flap facing the bolt has a longitudinal protrusion. 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 left cover has a reference hole that allows the hook to pass through it and the groove, and one of the covers has a reference hole for the adjustment handle of the arresting device. The arresting device may be spring loaded toward the rack or made of a resilient springly material.
EFFECT: improved functional reliability.
