SAFETY DOOR WITH FIGURED PROFILE CASE AND LEAF, COMPACT CROSSBARS, WITH BURIED OFFSET LOCKS, BURIED HANDLE, SAFETY SHUTTER AND BURIED HINGE STRAPS Russian patent published in 2008 - IPC E06B5/11 

FIELD: constructional engineering.

SUBSTANCE: invention refers to constructional engineering, in particular to safety doors. The safety door with figured profile case and leaf, compact crossbars, with buried offset locks, buried handle, safety shutter and buried hinge straps includes door leaf (leaf) articulated in door case and vertical pivot turnable. Lockset is made in the form of crossbar locks. The door leaf is compound and made of frame, barrier sheets, external and internal shutters. The frame is made of rigidly interconnected butt horizontal and vertical and centre racks. Locks are fixed on frame centre racks. Barrier sheets of specified thickness are curved and provided with apertures for keys, handle, security and visual devices, end faces being furnished with plugged apertures for pins junction. Barrier sheets are fixed on frame horizontal and vertical racks. The external shutter is mounted on external barrier sheet and on frame by buried loops, white the internal decorative shutter is fixed on internal barrier sheet and on frame by buried loops. Levers of lock handles sideshift from the lock are represented by elements movably interconnected between them selves and having their ends attached to external and internal handles through the lock. The electromagnetic lock is mounted on internal surface of the external shutter, and reciprocal component on external barrier sheet. Cover strip is fixed along the perimeter of door case. Packing seal is fixed along perimeter of the cover strip, door leaf and along perimeter of shutters. Heat-insulating and sound-insulating materials are provided in door leaf. Decorative platbands are fixed on door case. Buried loops rotating door leaf are fixed on door case and on frame. Locks are supplied with barrel bolt extender with stiffened crossbar on the end. The door case is made in the form of figured profile vertical and horizontal racks with groove on internal end face of perimeter. The frame of door leaf is made in the form of figured profile butt vertical and horizontal racks with groove on external end face of perimeter and of centre horizontal and vertical racks. Compact vertical and horizontal crossbars are used in the form of curved hollow or monolithic constructive components of shape corresponding to that of interconnected door case and leaf grooves. Compact vertical and horizontal crossbars are mounted in figured profile door leaf groove fixed in door case groove. Lock deviators are fixed on centre vertical racks of frame and interconnected with locks. Movable laths are shaped as stepwise curved sheets attached to lock and deviator crossbars with one vertical end faces, and to compact crossbars with the other vertical end faces. Compact horizontal crossbars are jointed to locks and lock deviators with pins and rods. Crossbar extenders of other locks and barrel bolt extenders with stiffened crossbar on the end pass through door leaf groove apertures and through compact crossbars fixed in door case groove. Door leaf dongles are shaped as stepwise curved sheets of shape corresponding to that of groove of butt horizontal racks of frame and barrier sheets. Door leaf dongles are fixed on butt horizontal racks of frame and upper and lower parts of barrier sheets. Lighting and biometric units are mounted on barrier sheets and on frame. Barrier sheets have apertures for lighting and biometric units, as well as plugged apertures at end faces for pins junction. The centre barrier sheet is fixed on frame under external barrier sheet. Inside the door leaf between complementary centre barrier sheet and external barrier sheet there is bulletproof material and polyurethane layer of high density. Packing seal is arranged inside groove along the perimeter of door case.

EFFECT: decreased laboriousness and ruling out illegal access to premise.
