Description

The proposed invention of the secret of the lock relates to door locks and can be used in mortise and overhead models.

This topic discusses several mechanisms for the secret of a lock with a recoding function, and examines the question of how quickly and conveniently it is possible for consumers themselves to change one type of key to another type, without replacing the lock secret.

Recoding a lock is the replacement of a secret code in a lock with a new code without replacing the secret of the lock.

Recoding the lock for the consumer is the replacement of the keys of the lock in the same secret, with keys with a different cut of combinations, i.e. one type of key is replaced by another type.

Otherwise, the installation key is replaced by the main key, then by the key from the spare set, etc. It is convenient and safe to have such an opportunity when installing a lock on a door, repairing an apartment, i.e., the situation when the key has been with strangers and there is a need to change only the secret of the lock itself, since there are no complaints about the rest of the lock mechanism.

The considered analogs of locks with recoding include the Chiz 57.966 lock. Let's consider how the lock secret is recoded. When the door is open, the lock is closed, the key is removed, then it is inserted into a special hole from the end of the lock and turned with a special square key, i.e. levers are installed under a new key, then we insert a new key and turn it to open.

The disadvantage of the analog is the fundamental existence of a special key, as well as the inconvenience of additional manipulation from the end of the lock, as well as the possibility of criminal penetration into the unprotected opening of the secret mechanism of the base model if it is not protected by additional protective pads installed outside the door.

A similar drawback is present in a whole series of Mottura locks 52J771 54J797 54J939 52J525 52J783 52J535 from the Mottura My Key series.

The closest analogue is the Calais cylinder-type lock with recoding, the set includes an assembly key, a recoding key and a set of main keys. Initially, you can use the installation key and the main keys, and after recoding the installation key will turn off.

For recoding, it is necessary to insert the recoding key into the secret of the lock and turn it until it stops, without removing the recoding key from the secret of the lock, return it to its original position, i.e. the bolts are pushed back into the lock, the recoding key is removed and the recoding has occurred.

The inconvenience when using the Calais lock is the presence of a recoding key between the installation key and the set of main keys, although there has been an improvement in the recoding in relation to the analog discussed above. Manipulation from the end of the lock is no longer required, like that of the Chiz 57.966 lock, but it is necessary to recognize the inconvenience in the very presence of a special recoding key for the Calais lock.

The disadvantage of an analog of the Calais lock, a cylinder type with recoding, is the very fundamental presence of a recoding key between the installation key and the set of main keys.

The closest prototype, in terms of technical essence to the claimed technical solution, is the Mul-t-Lock OMEGA PLUS® mortise lock. a rotary lock with a secret cylinder mechanism, which has the function of recoding between several types of keys - installation, main, spare and does not require special square or recoding keys.

The cylinder secret mechanism of the lock contains a secret body, an inner cylinder with an installed support post, support and code pins, a recoding ball and springs.

Recoding between types of keys occurs by pushing the recoding ball out of the internal rotary cylinder, it is the movement of the ball that leads to the replacement of secrecy with another type of key.

The disadvantages of the prototype, due to the minimization of the size of all internal parts of the secret of the lock, the size of the installation site of all internal parts is strictly limited, respectively;

There is no place in the secret mechanism to establish in it the internal details of a different, larger size or additional internal details of an already existing size, the introduction of which will make it possible to study and expand the function of transcoding between several or more types of keys.

It is impossible to increase the overall dimensions of the secret body, as this is interconnected with the design of other mechanisms in the lock.

It is impossible to increase the overall dimensions of the internal rotary cylinder, as this is interconnected with the secret body in which it is installed.

The disadvantage is the existing through hole between the support post and the code pins installed in the inner swivel cylinder, but not reaching the contact with the support post.

The disadvantage is the accelerated wear of code pins made of non-ferrous metal, the friction between the pins and the metal key leads to a decrease in their size, it is also possible complete or partial lack of lubrication, further accelerating wear and leading to incorrect operation of the entire secret mechanism.

The technical result is achieved by the fact that in the body of the secret, one or more annular grooves are made on the inside to establish in it a part of the diameter of the recoding ball that does not fit in a certain installation location, but when installed, it makes it possible to use complex recoding between several or more types of keys.

Also, the installation of additional parts, balls from the bearing around the support post - reduces friction and wear of the code pins and overlaps the through hole between the support post and the code pins.

The essence of the invention and the difference from the existing prototype;

- consists in setting a non-fitting part of the diameter of the recoding ball to a strictly defined installation location, while establishing it, which makes it possible to use recoding between several or more types of keys.

- consists in installing additional parts, balls from the bearing around the support post.

There is a decrease in friction and wear of the code pins, a through hole is blocked, the overlap of which prevents unauthorized penetration to the internal details of the secret of the lock, due to the slip that has appeared, it will be better to install the key in the rotary cylinder, the initially specified technological dimensions of the code pins are preserved, which positively affects the resistance resistance in a criminal investigation.

From practice. In production, the secrecy table was reset to zero, and it became necessary to install all the internal parts of the lock secret with minimally increased dimensions into the previously used secret assembly assembly.

The assembled secret body remained in the same overall dimensions, as it is interconnected with the dimensions of other mechanisms in the lock, and it cannot be quickly changed without a serious change in the design documentation.

An important issue for any production, alteration of existing equipment is always material costs and time spent on alteration, which is always not enough.

Otherwise, there was a need to establish the internal details of the secret of the castle, with a minimal, but still increased size, and the need to improve the existing structure in the form of installing additional details into it.

That is, without the possibility of changing the overall dimensions of the main body parts of the lock secret, install in them all the internal parts in a strictly defined place for their installation, with further use of the entire mechanism of the lock secret assembly.

All of the above correspond to the novelty of the invention and, of course, to the improvement of the operation of the secret mechanism, but it requires finding a place to install enlarged and additional parts.

To accomplish the above, a cylinder lock mechanism is proposed.

A schematic drawing of the assembled lock secret is presented.

in fig. 1, shows the secret of the lock assembly, in section, front view,

in fig. 2, the body of the secret is shown in section, side view,

in fig. 3 shows the mounting key.

The main and spare keys are not shown in the drawing, as according to the security table, they have the same assembly principle with the installation key.

The secret of the castle assembly, consists of the following parts;

in fig. 1 is a sectional front view of the lock assembly, consisting of the following parts;

position 1 secret body, position 2 rotary cylinder, position 3 support post,

position 4 conical springs, position 5 cylindrical support pins,

position 6 cylindrical coding pins,

position 7 balls from the bearing, position 8 recoding ball,

position 9 recess for recoding ball, position 10 retaining ring.

in fig. 2 shows a view of the body of the secret; position 11 grooves 3 pcs.

in fig. 3, view is shown, position 12 mounting key, position 13 holes of maximum depth 3 pcs.

The implementation of the invention, for the implementation of recoding between several different types of keys - these are assembly, main and spare keys;

The task is to establish all the internal details of the lock secret, shown in Fig. 1, made with specified dimensions, in a certain place of their installation, which has strictly limited dimensions;

- without changing the overall dimensions of the secret body 1 and the rotary cylinder 2 shown in FIG. one.

- without changing the dimensions of all the internal details of the lock secret shown in FIG. one.

To implement the invention, position 1, fig. 1 on its inner circumference, at the location of the holes for the support pins 5 and code pins 6, it is necessary to make at least one annular turning groove, shown in position 11, fig. 2.

The annular turning groove shown at 11 in FIG. 2 is necessary to place in it a part of the transcoding ball 8, which does not fit into the installation site when assembling the internal parts of the lock secret shown in FIG. one.

In the future, during the rotation of the inner rotary cylinder 2, the transcoding ball 8, with its non-fitted part, will always be in the groove position 11 of the secret body 1 shown in Fig. one

The secret case, position 1, shown in FIG. 1, with an annular turning groove 11 shown in FIG. 2, a rotary cylinder 2 is installed, and between them a spring-loaded latch, not shown in the drawing.

During rotation, the rotary cylinder 2 is fixed relative to the secret body 1, Fig. one.

Fixation between two parts occurs only in one position due to the actuation of a spring-loaded latch.

All through holes intended for all types of pins, located in different planes perpendicular to the axis of symmetry of the secret of the lock, are precisely combined, Fig. one.

The location of the spring-loaded latch, which occurs in different places of the lock secret, is determined by the secrecy table, it is not shown in the schematic drawing of the complete lock secret, due to its insignificance for the design and does not affect the explanation of this text.

The secret key of the lock from any type is installed in the secret of the lock always stably in the same position.

The size of the turning annular groove item 11 of Fig. 2, depends on the size of the transcoding ball 8, or rather its part - during assembly, which does not fit into the body of the secret 1, fig. 1, i.e. to a specific installation location, which has strictly limited dimensions.

An increase in the size of the groove is possible if it is necessary to increase the size of the recoding ball.

Increasing the size of the groove is more appropriate than changing the size of the code pin 6, the dimensions of which are limited by the overall dimensions of the secret of the lock assembly in Fig. 1, and the specified dimensions of all internal parts according to the security table.

Part of the recoding ball position 8, after assembling the secret of the lock, during the rotation of the rotary cylinder 2, will always be in the groove of the secret body shown in Fig. one.

The need for the number of grooves position 11 shown in Fig. 2, depends on the need to use the multiplicity of recoding, otherwise - the planned use of the type of key - assembly, main, spare keys.

All required key types are defined by the secret table.

The rotary cylinder, position 2, shown in FIG. 1 is installed in the body of the secret 1, the support post 3 is attached to it from the back.

On the circumference of the rotary cylinder, recesses 9 are drilled, of the required depth for the transcoding ball 8 to fall into them, at the required moment, Fig. one.

The location of the recesses and their required number depends on the planned use of the types of keys and are determined by the secrecy table.

The support post, position 3, shown in FIG. 1, fixed on the rotary cylinder 2, is mounted in the center of the rotary cylinder 2 of FIG. 1, and all the internal details of the lock secret are installed on it.

The installation of additional parts in the form of bearing balls 7, abutting against the support column 3, block the through hole between the support column 3 and the code pins 6, shown in Fig. one.

Support pins item 5, item 6 code pins shown in fig. 1, having a cylindrical shape and a diameter larger than the width of the groove of the secret body, position 11 of FIG. 2 are in constant contact with it, but do not interfere with rotation, which makes it possible for all parts of the secret mechanism to interact.

Code pin position 6 shown in FIG. 1, cylindrical in shape, with a transcoding ball 8 installed on it, the total length of such an assembly unit is slightly more than the place of its installation.

These two parts, when assembling the secret of the lock, are installed in one hole of the rotary cylinder 2, form one reserved unit, the separation of which is a distinctive feature from other code pins shown in Fig. one.

The length of the code pin 6 and the diameter of the recoding ball 8 are interconnected and determined according to the security table.

The balls from the bearing, position 7, shown in FIG. 1, are installed between the support post 3 and the code pins 6. After their installation, due to the emerging slip, the wear of the code pins 6 decreases, the decrease in wear is reflected in the better preservation of the specified dimensions that affect the opening resistance, the slip improves the installation of the key in the rotary cylinder 2 of Fig. 1 and block the through hole.

The transcoding ball item 8 shown in FIG. 1, this is a bearing ball, smaller than the required diameter, mounted on top of the code pin 6.

The diameter of the transcoding ball 8 of FIG. 1 depends on the dimensions of the code pins 6 on which it is installed, is visually distinctive from other bearing balls used in the lock of FIG. one.

The diameter of the transcoding ball 8 of FIG. 1 can be changed, but it is interconnected with the dimensions of the groove of the secret body, position 11 of FIG. 2, and the dimensions of the code pin 6.

It is possible to increase the size of the transcoding ball 8, while its movement in the groove, position 11 of FIG. 2, a movement exactly passing on the surface of the rotary cylinder 2 in the place of the holes with the code pins 6 installed in them.

The diameter of the transcoding ball 8, fig. 1 its applicability is determined by the secrecy table.

The general principle of recoding all types of keys.

Key recoding is the replacement of keys in the same secret of the lock of FIG. 1, into keys with a different cutting of combinations, i.e. there is a replacement of one type of key with another type, the replacement process is called recoding.

To manage the secret of the lock with recoding, keys of different types are used; keys mounting position 12, fig. 3, main, spare, not shown in the drawing.

To replace one type of key with another type, the existing calculation of changing the individual key number with given sizes in the secrecy table is applied.

All dimensions of all internal parts of the lock's secret are interconnected and determined by the table of secrecy.

Let's sequentially consider the use of different types of keys in one recoded secret; type keys - assembly, main, spare.

Replacing a key type with another key type occurs as follows.

To apply the recoding of keys, otherwise replacing the types of keys with each other, on the keys of all types on the circumference of each, on each row, according to the secrecy table, at least 1 piece is made. hole of maximum depth, position 13 of FIG. 3, the depth of the holes is equal to the length of the code pins 6, according to the individual key number determined from the security table.

To replace one type of key with another type, the required larger size must be provided on the key of the new type, leading to an irreversible replacement of the key type.

Change on the key of any type, even one depth of the hole, position 13 of Fig. 3, or changing its location, does not unlock the secret of the lock.

The mounting key, as well as the main and spare keys included in one recoding set of keys, have the form of a cylindrical shape and at least one hole of maximum depth, position 13, fig. 3 are made blind and the depth of the holes is equal to the length of the code pins 6.

All other required dimensions of the depths of the holes and their location are determined according to the individual key number according to the security table.

Changing on the mounting key 12, as well as on the key of any type, even one depth of the hole position 13, or changing its location, does not unlock the secret of the lock.

The use of the mounting key 12 makes it possible;

- when assembling the secret of the lock, set the code pin 6 and the recoding ball 8 to the reserved state.

- when the secret of the lock assembly with the mounting key 12 is working, the code pin 6 and the recoding ball 8 work, in a reserved state until they need to be disconnected.

The main key - has all the necessary holes for work and one provided size, necessary to replace the key type with another required type.

The main key - changes the mounting key, it is made with a larger size provided to eliminate the operation of the mounting key in one full turn of the key by 360 °, - the reserved code pin 6 will be disconnected, with the recoding ball 8 shown in Fig. one.

Those. the main key, made according to the table of secrecy with the provided increased size, will install all internal parts according to its key code, which ensures the possibility of rotation of the rotary cylinder and its further performance with this type of key, until the subsequent replacement with the next type of key.

Otherwise, on the main key, the maximum size provided will push the recoding ball 8 out of the hole of the rotary cylinder 2 into the hole of the secret body 1, under the spring-loaded support pin 5.

The operation and recoding of all types of keys - assembly, main and spare ones - takes place according to the same principle, according to the need to use the type of key determined by the secrecy table.

The secret of the lock assembly with the possibility of recoding, designed to work with several types of keys, is assembled according to the key that will be used first - this is the mounting key.

The secret of the lock prepared for the assembly of FIG. 1, is assembled according to the mounting key, in the hole intended for the pins, it is installed on the support post 3, the ball from the bearing 7, the code pin 6, the recoding ball 8, then the support pin 5 and the conical spring 4 are installed, other internal parts are installed according to the code key, i.e. final assembly of one row around the circumference of the mounting key.

The code pin 6 and the recoding ball 8 installed on it will work together with the rest of the parts, but is in a reserved state, until it needs to be disconnected - the main key.

Further, according to the table of secrecy, it is necessary to proceed to the installation of internal details for the next type of key - the main one, i.e. in the secret of the lock, a similar assembly of the next row around the circumference of the main key takes place, which will be used by the second - this is the main key.

The code pin 6 and the recoding ball 8 installed on it will also work together with the rest of the parts, but is in a reserved state, until it needs to be disconnected - with a spare key.

Further, according to the secrecy table, all internal parts are installed for the operation of the next type of key - a spare one, the installation of a code pin in a reserved state is no longer used, in the secret of the lock the last row is assembled around the circumference of the spare key, which will be used by the third - this is a spare key.

For the final completion of the assembly process, a retaining ring, position 10, shown in FIG. one.

There was an assembly of the secret of the lock with the possibility of recoding, for three types of keys, assembly, main, spare, the secret of the lock is ready for use.

In the considered version of the recoded lock secret, there is one unused turning annular groove 11 shown in Fig. 2, in which, by analogy with the ongoing assembly of the secret, it is at least possible to use one more set of spare keys No. 1.

The secrecy table provides for the use of several more spare sets of keys, but occurring at a different location of the code on the key, even with the condition of their use in three grooves.

Technically, in the secret of the lock, the recoding between key types occurs in this way.

Recoding between types of keys occurs by pushing the recoding ball out of the internal rotary cylinder into another plane, it is the movement of the ball that leads to the replacement of secrecy with another type of key.

The lock assembly shown in Fig. 1, with the possibility of recoding, for the consumer is no different from using the usual secret mechanism, the difference is only in the functionality provided to make the usual replacement of one type of key with another type.

It happens in the following way.

The mounting key 12 is inserted into the keyhole, i.e. in the rotary cylinder 2, in which the code pin 6 with the recoding ball 8 is installed, simultaneously with other internal parts, all of them are installed according to the code of the mounting key. The code pin 6 and the recoding ball 8 mounted on it work together with the rest of the parts, but are in a reserved state, until they need to be disconnected, i.e. the need to recode with the next type of key at the discretion of the consumer.

The main key, if necessary, is inserted into the keyhole, i.e. into the rotary cylinder 2, at this time, inside the secret of the lock, the code pin 6 moves upwards, with the recoding ball 8 installed on it, which is installed in the hole of the secret body 1, above the line of contact between the two main parts, the secret body 1 and the rotary cylinder 2 shown in FIG. one.

The transcoding ball, having moved out, is in the hole of the secret body even when the rotary cylinder rotates.

Otherwise, the internal parts of the lock secret were arranged according to the main key code, and everything is ready to disconnect the code pin 6, with the recoding ball 8 installed on it, since after the main key was inserted into the lock secret, the two parts ended up in different working planes.

Further rotation of the rotary cylinder 2 with the main key leads to the entry of the transcoding ball 8 located in the hole of the secret body 1 into the recess for the transcoding ball 9 intended on the rotary cylinder 2.

There was a separation of the code pin 6, with the recoding ball 8, which was in a reserved state, i.e. the disintegration of one former whole into two necessary parts, it is the movement of the recoding ball 8 into the intended recess 9 that leads to the replacement of secrecy with a different type of key.

The transcoding ball 8, after falling into the intended recess 9, is pressed by the base of the secret body 1 or, when crossing the holes, it is pressed by spring-loaded support pins 5 located in the secret body 1.

The rotary cylinder 2 has the possibility of unhindered rotation in the secret body 1, with the used recoding ball 8 installed in it, in the recess 9, which is no longer needed.

There is no possibility of an unintentional lunge of the transcoding ball 8 from the intended recess 9 during further rotations.

Further replacement of the secret for the spare key type follows the same principle, depending on the use of the key type defined by the secret table.

There was an introduction of the function of recoding the secret of the lock, between several different types of keys.

Recoding between different types of keys occurs by a one-time rotation of any type of key inserted into the secret of the lock by 360 °, without recoding keys and, moreover, any special additional devices.

Innovations and differences from the prototype.

1. The use of a groove in the body of the secret made it possible to install all the internal parts of the secret of the lock without changing their dimensions, in the secret of the lock assembly shown in Fig. one.

When applying innovation in the body of the secret assembly occurs;

- installation of the transcoding ball 8, in a limited place for its installation.

- without changing the overall dimensions, the main details of the lock secret shown in Fig. 1, secret body 1 and rotary cylinder 2.

- without changing the dimensions, all the internal details of the secret of the lock are used.

There was an introduction of a recoding function that works between several types of keys.

2. When using balls from the bearing 7, between the support column 3 and the code pins 6, occurs;

- reduction of wear of the code pins 6, while maintaining the specified dimensions affecting the resistance during a criminal autopsy.

- improvement of the installation of the key 12 in the internal rotary cylinder position 2.

- overlapping of the through hole, due to the installation of additional balls from the bearing 7, adjacent to each other and abutting against the support column 3.

EFFECT: balls from the bearing are used and the through hole is blocked between the support post and the code pins, which does not allow criminal penetration to the internal details of the lock secret.

In a limited installation area, without changing the overall dimensions of the main body parts, the implementation of the lock secret recoding function was implemented, which works between several different types of keys.

Recoding between different types of keys occurs directly by the varieties of keys themselves, i.e. the operation of the installation key is canceled with one turn of the main key, the operation of the main key is canceled with one turn of the key from the spare set, without the use of additional recoding keys and, moreover, manipulation from the end of the lock with special devices of various configurations.
