Description

The invention relates to the field of construction, namely, the design of security doors for special purposes. The claimed solution relates to designs of security doors that are resistant to burglary, containing a door frame with a door leaf movably fixed on it, which in the closed position is fixed in the door frame by locking and locking mechanisms (crossbars, bolts).

A known solution to the application RU No. 2003106755, dated 2003.03.11, ЕВВ 3/00. A door block, comprising a block frame, a door leaf movably fixed to the frame, consisting of a metal frame of a hollow profile. The hinges are equipped with an anti-removable device.

The advantage of the design is manufacturability.

However, the design does not provide protection against hacking of the door block, since access to the lock holes is open.

A known solution to the patent RU No. 2250338, from 2003.08.20, EB 5/11. A door unit comprising a door leaf pivotally mounted in a door frame with a possibility of rotation around a vertical axis, a locking device in the form of bolt locks, a rectangular metal frame, and the door leaf includes front, middle and rear metal sheets fixed to the frame. The door frame and frame are made of a composite profile.

The advantage is the flexibility of the manufacturing process through the use of one type of open section profile in the manufacture of both the door frame and the door leaf.

The assembly of the claimed technical solution is as follows. Door frame 1 is fixed in the doorway with anchor bolts. On the door frame 1, one part of the hidden adjustable hinges 13 is fixed, the other part of the hinges 14 is fixed on the frame 6. The protective sheet outer 2 and the protective sheet inner 3 are fixed on the racks of the frame 6. The frame 6 is made of horizontal 6.1 racks, vertical end 6.2 and middle 6.3 racks rigidly interconnected. On the vertical middle racks 6.3 fasten the locks 4, 5, 6 (locking the door leaf in the box). The lock bolts are equipped with extensions 6.9 or connected directly to the frame structure 6.10. Extenders of each lock 6.9 are connected in a frame structure 6.10, on the ends of which reinforced crossbars 6.11 are made, interacting with the end holes in the protective sheet outer 2. Extenders of the frame structure of the locks pass through the holes in the frame structure of other locks. Locks operate independently of each other. The locks are equipped with a tongue extension 6.12, which is driven by pressure on the door handle. The locks are equipped with a vertical locking device 6.8, placed up and down, the so-called "spider". Polygon ends of the vertical locking device interact with holes made in the horizontal struts of the frame 6.

On the outer 2 and inner 3 protective sheets, holes for the keys and for the handle are made. To protect against unauthorized access to the locks and the handle, an outer 4 door is additionally installed on the outer protective sheet 2 on hidden hinges. An electromagnetic lock 16 is installed on the inner surface of the outer door 4 for locking and unlocking the door 4, the counterpart of the lock is placed on the protective sheet 2. The offset inner door handle 8 is placed on the protective sheet 3 from the inside of the room, shifted from the lock placement by a certain distance by the levers 6.13. The levers with movably fixed elements 6.13.1 are connected at one end to an internal handle 8 and the other end through a lock with an external handle 7. On the protective sheet 3, on the inside of the room, an internal decorative door 5 is installed on hidden hinges, under which are key lock holes, security and other devices. On the component structures of the door leaf, protective caps 9 are attached from above and below. Thermal insulating and soundproof materials are placed inside the leafs. Along the perimeter of the box 1, the lash 15 and the sealing elements 18 are fixed. Under the outer and inner door, the sealing elements 18 are placed. Decorative platbands 10, 11, 12 are attached to the door frame.

Authorized access to the premises is as follows. After the magnetic card interacts with the electromagnetic lock, the door 4 is opened, providing access to the key lock holes and to the handle 7. After opening the locks, pressing the outer door handle 7, the tongue is unlocked and access is made to the room.

The claimed technical solution does not present difficulties for the current level of production. Design documentation has been developed and industrial production has been mastered. The design is collapsible, which increases the convenience of transportation and installation. The design is made at the request of the customer with various design solutions and a different set of equipment with various devices and devices.
