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, Е 05 В 17/18) is an analogue.

 There is also known a device for closing a keyhole, comprising a housing with an adjacent surface, fasteners, a shutter, a rod, a code change element, spikes, code pens with marks and holes (patent N 4773243, USA, 1988, CL 70-425) - prototype .

 The task to be solved by the claimed technical solution "Device for closing a keyhole" 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.

 The essence of the claimed device lies in the fact that in the device for closing the keyhole, comprising a housing with an adjacent surface, fasteners, a shutter, a rod, a code change element, spikes, code pens with marks and holes, according to the invention, the housing is made in the form of two supports, on the side surface of the shutter is made a cavity and two protrusions. On the end parts of the rod, on the side surface of the rod and on one of the end parts of the support, grooves are made. The protrusions are located in the grooves of the end parts of the rod. Code handles with tags are partially located in the hollow. The code change element is made in the form of washers or half washers with two legs. The spikes are made on the inner side surface of the washers or half washers and interact with a groove made on the side surface of the rod. The legs of the washers or half washers are located in the holes of the code pens with marks. Washers or half washers may be made of wire or sheet material.

A comparative analysis of the claimed device with the prototype shows that the device for closing the keyhole has common features with the prototype:
housing with an adjacent surface;
fasteners;
damper;
kernel;
code change element;
spikes;
code pens with tags and holes.

The inventive device differs from the prototype with new features:
the body is made in the form of two supports;
on the side surface of the shutter a cavity and two protrusions are made;
grooves are made on the end parts of the rod, on the side surface of the rod and on one of the end parts of the support;
the protrusions are located in the grooves of the end parts of the rod;
code pens with tags are partially located in the cavity;
the code change element is made in the form of washers or half washers with two legs each;
the spikes are made on the inner side surface of the washers or half washers and interact with a groove made on the side surface of the rod;
the legs of the washers or half washers are located in the holes of the code pens with marks;
washers or half washers are made of wire or sheet material.

 From the above list of features of the claimed device and the achievement of the task it is clearly seen that the claimed technical solution is a new set of features, as a combination of known and new features, providing a new technical result, unknown at the filing date of the application. A new technical result, which can be obtained by carrying out the invention, lies in the implementation of the task - the expansion of the arsenal of technical means designed to close the keyhole.

 The proposed device is industrially applicable, because it can be used in construction, industry, agriculture and other sectors of the economy where devices for closing a keyhole are used.

 The technical solution of the claimed device meets the criterion of "novelty", because it is not known from the prior art at the filing date of the application. Not known from the prior art, the set of essential features of the claimed technical solution and their impact on obtaining the desired technical result.

 The technical solution of the claimed device meets the criterion of "inventive step", because no solutions having features matching its distinctive features have been identified, and the influence of the distinctive features on the resulting technical result is not known.

 Thus, the claimed technical solution meets all the criteria for the invention and provides a new technical result.

 In FIG. 1 shows a general view of a keyhole closing device; in FIG. 2 is a view A in FIG. 1; in FIG. 3 is a section BB of FIG. 1; in FIG. 4 is a section BB of FIG. Z.

 A device for closing a keyhole, consists of a rod 1, a damper 2, code handles with marks 3 and holes 7, a support for the upper 4, a groove 5, a half washer 6 with legs 9, a groove 8, a cavity 10, screws 11, 12, a sleeve 13, fasteners 14, plates 15, mounting washers 16, studs 19, protrusions 20, depressions 21, marks 22, 23, bearings of the lower 24 and annular channels 25.

 The rod has three annular channels 25 (see Fig. 4). On the end parts of the rod 1, grooves are made (the position in Fig. Is not conventionally indicated), where the protrusions 20 of the shutter 2 are located. On the side surface of the rod 1, a groove 8 is made (see Figs. 1, 4). The damper 2 is fixed to the shaft by means of screws 11 (see Fig. 3). Code pens with tags 3 mounted on the rod 1 coaxially with the latter with the possibility of rotation. On the end part of the support of the upper 4, a groove 5 is made (see Fig. 1), which interacts with one of the protrusions 20. On the support of the upper 4 and on the support of the lower 24, marks 23, 22 are made, respectively. On the side surface of the shutter 2, a depression 21 is made, in which the code pens with marks 3 are partially placed. On the outer side surfaces of the code pens with marks 3, the marks are made in the form of numbers evenly over the entire surface of the handles. At the end parts of the code pens with marks 3, cavities 10 and openings 7 are made (see Fig. 4). In the cavities 10 are placed half washers 6 with legs 9, while the legs 9 are placed in the holes 7. The spikes 19, which are made on the inner surface of the washers 6, are placed in the annular channels 25 with the possibility of interaction with the groove 8.

 The distance between the centers of the legs 9 is equal to the distance between the centers of the holes 7 located diametrically opposite. Mounting washers 16 are installed between the supports 4, 24 and the plate 15 to provide a fixed gap between the code handles with marks 3 and the plate 15 (see Fig. 2). On the supports 4, 24 marks 23, 24 are made, which must be guided when setting the required code. In FIG. 2 poses 18 marked keyhole of the castle, and pos. 17 indicates a door or door leaf. The device is fixed to the door surface by means of screws 12, bushings 13 and fasteners.

 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 3 (upper) around the axis of the rod 1 so that the number "1" coincides with the mark 23 of the support of the upper 4 (see Fig. 1). Then we turn the code knob with the marks 3 (middle) around the axis of the rod 1 so that the number "5" coincides with the mark 23 or 22. Then we also combine the number "9" of the code handle with the marks 3 (lower) with the mark 22. As a result this spikes 19 (see figure 4) of all three half washers 6 will be placed in the groove 8 and the rod 1 becomes able to make a reciprocating movement up together with the shutter 2 by the value of "h". When moving the rod 1 up, the protrusion 20 leaves their groove 5. After that, they take on the shutter 2 (see Fig. 1, 2) and rotate it together with the rod 1, freeing up the space above the keyhole 18. Then take the key and enter it into the keyhole 18 of the castle and open the castle.

 To change the code, disassemble the device, and then change the location of the half washers 6 and their protrusions 19 relative to the groove 8. To do this, raise the half washers 6 and place their legs 9 in the other diametrically opposite holes 7. The device is closed 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.
