Description

 The invention relates to devices for closing a keyhole and can be widely used for locks of any systems to prevent unauthorized access to the keyhole of a castle.

 A device for closing a keyhole, comprising a housing with an adjacent surface, fasteners, a damper with spikes and code pens with tags and code mechanisms (patent N 2132437, Russia, 1999, E 05 B 17/18) is an analogue.

 A device for closing a keyhole is also known, comprising a housing with an adjacent surface, fasteners, a shutter, a rod, a code change element, spikes, code pens with marks and holes (patent N4773243, USA, 1988, CL 70-425) - prototype.

 The problem to which the claimed technical solution is directed is to expand the arsenal of technical means for devices designed to close a keyhole.

 The technical result that can be obtained by implementing the device is to implement the task - expanding the arsenal of technical means for closing the keyhole.

 Figure 1 shows a General view of a device for closing a keyhole; figure 2 is a section aa in figure 1; figure 3 is a section bB of figure 2.

 A device for closing a keyhole consists of a shutter 1, a rod 2, a housing with an adjacent surface 3, a mark 4, code handles with a mark 5, holes 6, a groove 7, a latch 8, annular cavities 9, legs 10, fasteners 11, material elements 14 and spikes 15.

Заслонка может быть выполнена в виде самостоятельной детали, которая закрепляется к концевому участку стержня 2 или может быть выполнена в виде концевого участка стержня без какой-либо дополнительной детали (условно данное исполнение не показано). На поверхности стержня 2 (см. фиг.2) выполнены, например, три кольцевые впадины 9 и паз 7. На корпусе с прилегающей поверхностью 3 закреплен фиксатор 8, который взаимодействует с пазом 7. Фиксатор 8 предохраняет стержень 2 от поворота вокруг собственной оси. Корпус с прилегающей поверхностью 3 выполнен в виде двух частей, которые закрепляются к поверхности двери или к поверхности дверного полотна 12 посредством крепежа 11. На одной из частей корпуса 3 выполнена метка 4, которая показывает на место расположения паза 7. Кодовые ручки с метками 5 установлены на стержне 2 с возможностью поворота. Кольцевые впадины 9 сообщены с пазом 7. На торцевых частях кодовых ручек с метками 5 выполнены полости (позиция условно не показана), где размещены материальные элементы 14 (см. фиг.3). Материальные элементы 14 имеют ножки 10 (см. фиг.2), которые размещены в отверстиях 6. Отверстия 6 выполнены на торцевых частях кодовых ручек с метками 5, напротив цифр-меток, выполненных на наружной поверхности кодовых ручек с метками 5 (от "0" до "9"). Материальные элементы 14 с ножками 10 могут быть выполнены:

образ -shaped, □ -shaped,

-shaped, etc. The damper can be made in the form of an independent part, which is fixed to the end section of the rod 2 or can be made in the form of an end section of the rod without any additional parts (conditionally this design is not shown). For example, three annular cavities 9 and a groove 7 are made on the surface of the rod 2 (see FIG. 2). A latch 8 is attached to the housing with an adjacent surface 3, which interacts with the groove 7. The latch 8 prevents the rod 2 from turning around its own axis. The case with an adjacent surface 3 is made in the form of two parts, which are fixed to the door surface or to the surface of the door leaf 12 by means of fasteners 11. On one of the parts of the case 3 a mark 4 is made, which indicates the location of the groove 7. Code handles with marks 5 are installed on the rod 2 with the possibility of rotation. The annular cavities 9 are communicated with a groove 7. On the end parts of the code pens with marks 5, cavities are made (the position is not shown conditionally), where the material elements 14 are placed (see Fig. 3). Material elements 14 have legs 10 (see FIG. 2), which are located in holes 6. Holes 6 are made on the end parts of the code pens with tags 5, opposite the number tags made on the outer surface of the code pens with tags 5 (from "0 "to" 9 "). Material elements 14 with legs 10 can be made:

-shaped;

-shaped;

-shaped;
Λ-shaped.

The spikes 15 are made on the material elements 15 and interact with the groove 7. The rod 2 is mounted with the possibility of reciprocating movement relative to:
material elements 14 with spikes 15 and legs 10;
cases with an adjacent surface 3, code pens with tags 5;
latch 8;
fasteners 11;
door leaf or surface of door 12 and keyhole 13.

 Keyhole 13 is located on the surface of the door or door leaf 12 (see Fig. 2). The damper 1 or the end part of the rod 2 is installed above the keyhole 13 (in the closed position). The legs 10 are made in one piece with the material elements 14. However, the legs can be made in the form of separate elements, for example screws, bolts, pins, nails, etc., which are fixed to the material elements 14.

 The device operates as follows.

 Assume the device’s unlock code is “159”. To open the device, perform the following steps. We turn the code knob with marks 5 (upper) around the axis of the rod 2 so that the number "1" coincides with the label 4 of the case with the adjacent surface 3 (see Fig. 1, 2). Then we turn the code knob with labels 3 (middle) around the axis of the rod 2 so that the number "5" coincides with the label 4 of the body with an adjacent surface 3. Then we also combine the number "9" of the code handle with labels 5 (lower) with the label 4 As a result of this, the spikes 15 (see Fig. 3) of all three material elements 14 will be placed in the groove 7 and the rod 2 will be able to make a reciprocating movement down by the required amount, for example, 25 mm. As a result of moving the rod 2 with the shutter 1 or without the shutter 1, the rod 2 with the shutter 1 or without the shutter 1 opens the space above the keyhole 13 for introducing the key into the keyhole 13. Then take the key and enter it into the keyhole 13 and open the lock. After opening the door, the rod 2 is lifted up, then the code handles with marks 5 are shifted relative to the label 4 and the rod 2 is released, while the shutter 1 or the end part of the rod 2 will overlap the keyhole 13. The rod 2 will be held on the spikes 15, which are placed in the ring troughs 9.

 To change the code, disassemble the device, and then interchange the code pens with labels 5. Change the code can be done in another way. Disassemble the device, and then change the position of the spikes 15 relative to the code pens with marks 5 by lifting the material elements 14 with legs 10 and then placing the legs 10 in other diametrically opposite holes 6. Closing the device is carried out in the reverse order.

 Thus, the claimed technical solution of the device for closing the keyhole ensures the achievement of the task and obtaining a new technical result.
