Description

 The invention relates to methods for closing a keyhole and metal doors and can be widely used for locks of any structure having a keyhole to prevent unauthorized access.

 There is a method of closing a keyhole, including blocking the well with a cover by turning it towards the well (patent N 2096568, USA, CL 70-455, 1937) - analogue.

 Known metal door containing the box and the door leaf (patent N 2053344, Russian Federation, 1994, E 06 B 5/10) - analogue.

 The disadvantage of this method is that for its use requires additional special material objects.

 A disadvantage of the known metal door is that the device has limited functionality and does not provide for locking a keyhole lock.

 There is also a method of closing a keyhole, which consists in moving the material body (cap, flapper, cover, etc.) into the keyhole zone (patent N 2247592, 1941, USA, CL 70-455) - prototype.

 Also known is a metal door containing a box, a frame, a door leaf with an opening for a lock element with a keyhole and a lock with a keyhole (patent N 2039182, Russian Federation, 1992, E 06 B 5/06) - prototype.

 A disadvantage of the known method of closing a keyhole is that for its use additional special material bodies (caps, dampers, covers, etc.) are also needed by which the keyhole is closed.

 A disadvantage of the known metal door is that the device has limited functionality and does not provide for closing the keyhole of the castle.

 The problem, which is aimed by the claimed technical solution for the object "Method of closing a keyhole", is to expand the arsenal of technical means for methods of closing a keyhole.

 In FIG. 1 shows a general view of a device for implementing a keyhole closing method; in FIG. 2 is a section AA in FIG. 1 enlarged view; in FIG. 3 - configurations of windows made on the edge of the door leaf in the area of door hinges.

 A metal door consists of a box 1, frame 2, door leaf 3 with an opening for a lock element with a keyhole 4, a lock 5 with a keyhole 6, lower guides 7, lower support elements 8, lower brackets 9, springs 10, bolt 11, upper half-loop 12, lower half-loop 13, axles 14, windows 15, handles 16, upper guides 17, upper support elements 18 and upper brackets 19.

 Box 1 (see Fig. 1) is made of separate parts of a metal pipe (any other profile can be used), welded together in a closed loop. The frame 2 is made of separate parts of the corner, also welded together in a closed loop. The door leaf 3 is made of sheet material in which a hole 4 is drilled for a lock element with a keyhole. The lock 5 with the keyhole 6 is fixed by means of fasteners to the frame 2. The lower guides 7 are rigidly fixed to the lower part of the frame 2. The lower supporting elements 8, by means of the lower brackets 9, are rigidly fixed to the door leaf 3 and partially placed in the lower guides 7. Lower supporting the elements 8 are mounted with the possibility of movement relative to the lower guides 7. The springs 10 are installed inside the lower guides 7 under the lower supporting elements 8. The crossbar 11 of the lock 5 interacts with the hole when closing the door, you filled in the box 1. The upper half-loop 12 is rigidly fastened to the frame 2 (see Fig. 1 and 2). The lower half-loops 13 are rigidly fastened to the box 1. The axles 14 are rigidly fastened to the lower half-loops 13. The upper half-loops 12 are mounted with the possibility of rotation relative to the axes 14. On the door leaf 3 (see Fig. 3), in the area of the door hinges (the concept of “hinge” includes: upper half loop 12, lower half loop 13 and axis 14) windows 15 are made with a height of "Q". The handle 16 is mounted on the surface of the door leaf 3. The upper guides 17 are rigidly fixed to the upper part of the frame 2. The upper support elements 18 are rigidly fixed to the door leaf 3 by means of the upper brackets 19 and partially placed in the upper guides 17. The upper support elements 18 are movably mounted relative to the upper rails 17. The height of the door hinges is "S". The distance between the upper parts of the half loop 12 and the upper parts of the windows 15 is "H". With the door closed, the distance between the center of the hole 4 and the center of the keyhole 6 of the lock 5 is also "H". The door leaf 3 is installed with the possibility of limited movement by the amount of "H" and with a guaranteed gap "h" (a gap of the order of 0.1 mm) relative to the box 1 and the frame 2, while Q = H + S. To adjust the gap "h" use adjusting gaskets, which are installed, if necessary, between the lower brackets 9 and the door leaf 3, between the upper brackets 19 and the door leaf 3.

 The method is implemented as follows. In FIG. 1 shows a general view of the metal door in the closed state, while the keyhole 6 of the lock 5 is closed by the door leaf 3. To open the door, grab the handle 16 (see Fig. 1) and move it down all the way, while the door leaf 3 moves strictly by the value of "H" (the specified value can be any and is determined by the design features of the lock, in our case, the displacement is 40 mm). As a result of the movement, the hole 4 is aligned with the keyhole 6. The key is installed in the keyhole 6 and, turning the key, the bolt 11 is taken out of the hole in the box 1. When the door leaf 3 is moved down, the springs 10 are compressed, and the lower supporting elements 8 move along the lower guides 7, the upper supporting elements 18 are moved along the upper guides 17. When the door leaf 3 is moved down by an amount of "H", the upper edges of the windows 15 (see Fig. 3) interact with the upper half-loops 12. Then the key they are locked from the keyhole 6 and the handle 16 is released. Under the action of the springs 10, the door leaf 3 moves upward by the value “H”, while the lower parts of the windows 15 interact with the lower half-hinges 13. The door hinges act as limiters for the movement of the door leaf 3. In the process of moving the door leaf 3, the latter does not interact with the frame 1 and the frame 2, since there is a gap “h” between the specified parts (see FIG. 2). After that, using the handle 16, the frame 2 is rotated together with the door leaf 3 and the upper half loops 12 relative to the axes 14 by the required angle, which ensures passage through the internal volume of the box 1.

 The operation of the device is described in the description of the implementation of the method.

 Thus, the claimed technical solutions of the method of closing the keyhole and device for its implementation ensure the achievement of goals and obtaining a new technical result.
