Description

 The invention relates to combination locks and can be used for doors, safes, drawers, chests and vehicles.

 Known lock code, containing a housing with a label or tags, a bolt or bolt, code elements with tags and a means of protection against unauthorized selection of a code (RU 2161684 C1, E 05 B 37/00, 01/10/2001).

 The problem to which the claimed technical solution is directed is to expand the arsenal of technical means for the construction of the castle.

 The technical result that can be obtained in the manufacture of a combination lock is to implement the above task - expanding the arsenal of technical means.

 The essence of the claimed device lies in the fact that the combination lock, comprising a housing with a mark or tags, a bolt or deadbolt, code elements with tags and a means of protection against unauthorized selection of a code, according to the invention is additionally equipped with an insulator, and code elements with labels, an insulator and a protection means from unauthorized selection of the code made in the form of coaxially mounted relative to each other rings with grooves and form at least one privacy module. Code elements with labels are kinematically communicated with a means of protection against unauthorized selection of a code, and an insulator is placed between the surface of a subsequent code element with labels and the surface of a means of protection against unauthorized selection of a code kinematically connected with the surface of a previous code element with labels. The insulator is fixed relative to the housing, and the crossbar or deadbolt is installed perpendicular to the surface of the code elements with marks and the insulator. The grooves are made on the code elements with marks, on the insulator and on the crossbar or deadbolt, and at least one groove on the crossbar or deadbolt is made with the possibility of kinematic interaction with the code elements with marks and means of protection against unauthorized selection of the code, and the inner diameter of each subsequent ring , in the form of which code elements with labels are made, less than the inner diameter of the previous ring.

 The crossbar or deadbolt is made in the form of a plate or part of a Y-shaped or + -shaped shape.

 Code elements with labels are kinematically communicated with a means of protection against unauthorized selection of the code by means of grooves or holes made on the code elements with labels, and by means of protuberances made on the means of protection against unauthorized selection of the code.

 The insulator is fixed relative to the housing by means of an opening made on the housing and by a protrusion made on the insulator.

A comparative analysis of the inventive combination lock with the closest analogue shows that the common features are:
- case with a tag or tags;
- deadbolt or deadbolt;
- code elements with labels;
- a means of protection against unauthorized selection of code.

The inventive castle differs from the closest analogue with new features:

- the bolt or bolt is made in the form of a plate or part of a U-shaped or + -shaped shape;
- code elements with labels kinematically communicated with a means of protection against unauthorized selection of the code by means of grooves or holes made on the code elements with labels, and by means of protuberances made on the means of protection against unauthorized selection of the code;
- the insulator is fixed relative to the housing by means of a hole made on the housing, and by a protrusion made on the insulator.

 From the above list of signs of the claimed code lock 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 signs, providing a new technical result, not known at the filing date of the application. A new technical result that can be obtained by carrying out the invention is to expand the arsenal of technical means for the construction of a code lock.

 Figure 1 shows a General view of the lock code; figure 2 - a view of figure 1; figure 3 is a section bB of figure 1; figure 4 is a view In figure 1; figure 5, 6 and 7 show the individual details of the code lock; in Fig.8 is a view of G in Fig.7; figure 9 shows the individual execution of the code lock; figure 10 is a cross-section BB of figure 1 with a different design of the code lock.

 The code lock contains a housing 1, mounting holes 2, a bolt or deadbolt 3, code elements with tags 4, a turning means 5, a cover 6, a limiter 7, a means of protection against unauthorized selection of a code 8, an insulator 9, protrusions 10, holes 11, grooves 12 , 13, 14, 15, bulge 16 and mark 17.

 Case 1 (see figures 1, 2, 9), mainly made in the form of a glass for one privacy module, two, three, four, etc. privacy modules. Mounting holes 2 are made on the peripheral part of the housing 1 for fixing the code lock to the supporting surface by means of fasteners (screws, bolts, etc.). The crossbar or deadbolt 3 can be made, for example, in the form of a plate with one or more grooves (the position of the groove or grooves is not indicated), in the form of a Y-shaped or + -shaped part (see Fig. 9). Code elements with labels 4 (see figures 1, 3, 6) are made in the form of separate rings with turning means 5 and grooves 14 and 13 (instead of grooves, pos. 13, holes can be made). The grooves are necessary for the kinematic connection of code elements with tags 4 with means of protection against unauthorized selection of code 8 by means of bulges 16 (see Figs. 7, 8). On the front side of the code elements with labels 4, rotation means 5 are made in the form of bent parts of the material from which the code elements with labels 4 are made. The rotation means can also be made in the form of separate holes. The rotation tool can also be performed in any form, and it is necessary to ensure the rotation of the code elements with labels 4. Marks on the surface of the code elements 4 can be made either in the form of numbers or in the form of letters or in the form of any signs and symbols. Cover 6 (see Fig. 2) holds code handles with tags 4, means of protection against unauthorized selection of code 8 and insulators 9 in the internal cavity of the housing 1. In the cover 6, holes are made, combined with the holes of the fixing 2 of the housing 1 and the hole (position conditionally not indicated) under the deadbolt or deadbolt 3. The limiter 7 is fixed to the deadbolt or deadbolt 3 and restricts the movement of the deadbolt or deadbolt 3 by a predetermined amount. The limiter can be made in the form of a threaded element (screw, bolt, etc.) or in the form of a cotter pin. The means of protection against unauthorized selection of the code 8 is made in the form of separate rings with grooves 15 and bulges 16. These rings through the bulges 16 kinematically interact with the code elements with labels 4 and can only be rotated together with the latter. Moreover, the code elements with labels 4 and the means of protection against unauthorized selection of the code 8 kinematically interact with each other in such a way that the groove 14 is aligned with one of the grooves 15, and the deadbolt or deadbolt 3 can freely move through the groove thus formed. The insulator 9 (see figure 5) is made in the form of separate rings with a groove 12 and a protrusion 10 (see figure 4, 1). The functional purpose of isolator 9 is to limit contact between one code elements with labels 4 and neighboring means of protection against unauthorized selection of code 8, fastened with other code elements with labels 4. If you do not install insulators 9, then when you rotate one code element with labels 4, it will be transmitted rotation to other code elements with labels 4, and setting the required code will be difficult. The protrusions 10 are designed to fix the insulator 9 relative to the housing 1. In the housing 1 there is a hole 11 in which the protrusions are mounted 10. One groove is made on the crossbar or deadbolt 3 (see Fig. 3, the groove is conditionally not indicated by the position), while the pack of rings installed in the internal cavity of the housing 1, is installed with the possibility of kinematic interaction with the specified groove. Several grooves can be made on the bolt or bolt 3 (see Fig. 10), while each code element with marks 4 and with a means of protection against unauthorized selection of code 8 kinematically interacts with a separate groove on the bolt or bolt 3. The grooves are separated from each other friend jumpers. The mark 17 is made on the housing 1 (see figure 1).

 Code lock works as follows.

 To unlock the code lock, do the following:

 Take the rotation means 5 (see FIGS. 1, 2) in order of each of the three code elements with labels 4 and rotate them, combining the required number with the label 17. Transfer the code elements with labels 4 together with the means of protection against unauthorized selection of code 8 in the "open" position by turning them, while one of the grooves 15 and the groove 14 (see Fig.6, 7) are combined with a bolt or deadbolt 3 (see Fig.3, 10). Then take the deadbolt or deadbolt 3 and move it towards you, while the deadbolt or deadbolt 3 moves to the end, and the stopper 7 (see Figs. 3, 10, 2) rests on the cover 6. The code lock is open.

 To lock the code lock, the deadbolt or deadbolt 3 is moved away from itself until it stops, then the code elements are rotated together with tags 4 and a means of protection against unauthorized selection of code 8, the slots 15 and 14 are removed from kinematic engagement with the deadbolt or deadbolt 3.

 Thus, the claimed technical solution "Code lock" ensures the achievement of the task and obtaining a new technical result.
