Description

The present invention relates to locking devices and can be used in overhead, mortise locks for doors of residential buildings, safes, etc.

This topic discusses the internal mechanisms of the lock, which are poorly protected against the forceful method of burglary, when, with the help of a mount or a specialized tool, access to the end of the crossbars is created, and the bolt is pushed or driven into the lock body with breakage of internal nodes and parts of the lock mechanism.

Deadbolt: a part of the lock that serves to fix the door leaf in the closed position by means of the entrance to the strike plate, extract of GOST 5089-2003, hereinafter referred to as the crossbar frame, shown in Fig. 1, position 2.

This criminal power method is applicable to the overwhelming number of locks with any type of internal device, the mechanism of which is not protected by the installation of additional parts or assemblies that can provide serious resistance to hammering the bolt.

There are very few locks with the use of additional parts, units, the purpose of which is to protect the internal mechanisms of the lock from the criminal method of driving the bolt, I have not found locks with additional units, in the full technical sense of this term.

The first question is being investigated - the possibility of using additional protection, created in the form of a separate independent unit, capable of protecting the lock from hammering the deadbolt.

The second question is being investigated - the possibility of using one more additional protection, created in the form of a separate independent unit, which, being the second, will itself protect the lock from hammering the bolt, and by its location, above the already created first protection, will physically redraw the possibility of access to it.

Those. the second protection, which is a second separate independent unit, also has a double functional purpose.

In view of the creation of two independent rigid protections, each of them will be performed more and more intensively, it is necessary to take into account. That, in case of criminal hammering of the bolt, the force of the blow will pass through the bolt, two reinforced rigid protections, which will be difficult to bend, and then act on only one rear wall of the lock case, which will turn out to be the weakest link in the resistance chain.

Thus, in view of the creation of two independent reinforced rigid protections, it is necessary to strengthen the rear wall of the lock body, after strengthening which it will be the third protection, preventing the possibility of unbending the rear part of the lock body with criminal blows.

The third issue is being investigated - the possibility of using additional security measures that enhance the functional ability for the first two, created in the form of separate parts or an independent unit capable of protecting the lock from hammering the bolt.

These three created defenses, not only, will greatly complicate the use of the criminal forceful method of driving the bolt, but the presence of one of them will fundamentally exclude even unauthorized access to the other two.

On the topic of the issue under consideration, a market study of the presented domestic and foreign locks showed that there are no analogues to the invention.

The considered analogue of the lock, which in itself is very conditional, can be attributed to the Barrier-Prime lock, developed on the basis of patent No. 2387774, which has protection against hammering the bolt made in the form of a movable rotary stop driven from the protective rotary sleeve of the lock interacting with the rotary plate focusing through the gear system.

In the closed position of the lock, the movable fan-shaped rotary plate abuts against the bolt frame, thereby preventing the bolts from being hammered into the lock body.

In this case, it is enough to turn the protective sleeve all the way in the direction of unlocking the lock, using any key suitable for the profile, or a metal hook, and the protective part will turn at an angle sufficient to stop resting on the deadbolt frame and thereby stop blocking the bolt.

In this case, the entire load arising when trying to hammer the bolt falls on one locking post, the bolt shank lock.

The disadvantage of this mechanism is the possibility of unauthorized disabling of protection by turning the protective drive sleeve using a hook-shaped part selected in size, or any key blank suitable for the overall dimensions and profile, while unlocking the lock secret is not required, and the deadbolt frame is held only by one locking post of the bolt shank.

The disadvantage of the analogue is weak protection of the lock mechanism from hammering the bolt, the possibility of unauthorized disabling of protection, bypassing the secret of the lock.

The closest prototype, which is also very conditional, to the proposed technical solution is the Chiza lock 57665 basic, the bolt clogging protection in it is made in the form of a spring-loaded bolt delay plate with the ability to move it perpendicular to the bolt. When the lock is locked for all four turns, this plate abuts against the plate fixed to the deadbolt frame, and at the same time serves as a drive for vertical rods. In this case, it is enough to insert into the keyhole and turn all the way to the stop any key blank suitable for the profile, or a hook, and the plate that prevents clogging of the lock bolt will rise up and cease to perform its function.

The disadvantages of the prototype, in the considered lock, protection against clogging the bolt, has the possibility of unauthorized shutdown using the simplest devices used.

Creation of the first hard protection, which, without unauthorized unlocking of the lock secret and elimination of the proposed first protection, will not make it possible to drive the bolt into the lock body.

Creation of a second rigid, additional protection, created in the form of a separate independent unit, capable of independently protecting the lock from hammering the bolt and at the same time preventing criminal access to the first created protection.

Those. protection originally with a dual functional purpose.

Creation of the third hard protection, by adding separate parts, the use of which will strengthen the rear of the lock case.

In case of criminal hammering of the crossbar frame and the first two created rigid protections into the lock body, the created third rigid protection, in the form of a reinforced rear part of the lock body, will prevent the rear wall of the lock body from unbending from almost all blows applied to it.

The essence of the invention and the difference from the existing prototype is that without unauthorized unlocking of the secret of the lock and the elimination of the three created defenses;

- the first tough defense, the main one.

- the second rigid, independent additional protection, blocking criminal access to the first.

- the third rigid protection, which performs the function of strengthening for the first two, it would be impossible, without destroying three of them, to drive the frame of the crossbars into the lock body.

The first task is to create the first independent rigid movable stop between the deadbolt frame and the lock body in the rear lower part of the lock body.

The second task is to create a second independent additional movable stop in the rear upper part of the lock body, between the secret of the lock and the lock body, at the same time overlapping with its location the existing stop created in the lower rear part.

The third task is to create a rigid protection in the rear part of the lock body by introducing additional parts into the lock structure designed to strengthen the first two protections.

The simultaneous use of three rigid protections interacting with each other is a serious obstacle to the criminal clogging of the bolt. Presented are schematic drawings of the developed units of the castle;

In the lock body 1, the crossbar frame 2 is installed in such a way that its horizontal and vertical movement does not interfere with the operation of any mechanism that is in constant contact with it, shown in Fig. 1, fig. 2A, fig. 5 and FIG. 6.

Vertical rods 2 pcs., Position 3 and position 4, shown in Fig. 1, fig. 2A, fig. 3 and FIG. 5.

One protection should be located above the other protection, completely overlapping it, and it is necessary to use for this purpose the vertical rods available in the structure of the castle, redoing them.

Vertical rods 2 pcs., Position 3 and position 4, are installed in the upper rear part of the lock case, move only vertically and both are intended for connection with deviators.

Deviators are additional protection installed on the door, usually metal.

In vertical movement, both rods are driven from the transom frame 2, which in turn interacts with the secret of the lock 12, shown in Fig. 1, Fig. 5, figs. 6.

Both vertical rods are structurally provided by their location in the upper rear part of the lock body so that they almost completely block access to the rigid movable stop installed under them, position 6, shown in Fig. 1, fig. 2, fig. 5 and FIG. 6.

Both vertical rods are located, between the secret of the lock assembly 12 and the corner 13, installed as follows, the vertical rod is the upper position 3, installed on the vertical rod with the lower one with a bend angle of 90 °, position 4, and both are installed on two posts 10, in the upper rear part of the lock, position 6 above the rigid movable stop is shown in FIG. 2A, fig. 5 and FIG. 6.

Between the vertical lower rod with a bend angle of 90 °, position 4, and a rigid movable stop, position 6, 2 springs are installed on the posts 10. position 5, everything is shown in FIG. 1, fig. 2 fig. 5 and FIG. 6.

The lower vertical link 4, made with a bend angle of 90 °, is shown in Fig. 1, fig. 2, fig. 5, figs. 6 and FIG. 7.

The vertical link upper position 3 shown in FIG. 5, fits snugly on one flat side, to the upper part of the lock assembly 12, with the other flat side abuts against the corner 13, shown in Fig. 2.

One folded side with a bend angle of 90 ° is specially made so that, in addition to the functional purpose of the vertical rod, as such, it simultaneously performs the function of an additional stop, after being installed in the intended place, shown in Fig. 2A.

With a bent corner, and its location should reinforce the rear wall of the lock case 1, in case of criminal hammering of the crossbar frame 2 into the lock case 1.

The bend angle itself is 90 °, from the vertical pull of the bottom 4, is installed under the corner 13 and this is double reinforcement.

Springs 2 pcs., Item 5, are shown in Fig. 1, fig. 2, are installed on racks of 2 pcs., Position 10 is shown in Fig. 3, the place of installation between the vertical lower rod with a bend angle of 90 °, position 4, and a rigid movable stop, position 6, 2 springs are installed on the posts. position 5, everything is shown in FIG. 2 and FIG. 3.

The rigid movable stop position 6 shown in FIG. 3, an independent rigid movable stop between the frame of the crossbars and the lock body, the spring-loaded movable part is installed on two posts 10, 2 springs are installed on both posts, position 5, abutting against the rigid movable stop, position 6 and the lower vertical rod with a bend angle of 90 ° position 4 is shown in FIG. 1, fig. 2A.

A rigid movable stop position 6 is installed in the rear lower part of the lock body between the frame of the crossbars 2 and the lock body 1, and performs the function of an independent rigid movable assembly assembly, capable of independently protecting the lock from criminal clogging of the crossbar frame 2, into the lock body 1, shown in fig. 2A, fig. 3 fig. 5.

On the rigid movable stop position 6, powerful projections are provided on both sides, tightly fitting the frame of the crossbars 2, shown in Fig. 3, which do not give the possibility of changing the trajectory of movement in the case of criminal influence, except directly on the rigid movable stop 6, is shown in FIG. 3.

On top of the rigid movable stop position 6, on a permanent basis, a plate is attached, fitting position 7, shown in Fig. 1, fig. 2, fig. 5, figs. 6 and FIG. 7.

Provided that the lock body 1 and the cover 11 are connected, on which the lock assembly 12 is installed, the rigid movable stop position 6, the lock assembly 12 and the bolt frame 2 interact, shown in Fig. 3 and FIG. 6.

The schematic drawing does not show the installation of the cover 11 with the mounted secret of the lock assembly 12 on the lock body 1, due to the simple obviousness of the ongoing process.

To raise the rigid movable stop, position 6, and install it on the frame of the crossbars, position 2, a 45 ° bevel is provided on the rigid movable stop in a certain place, shown at position 6, Fig. 7.

In addition to the designated place for a 45 ° bevel, the rest of the rigid movable stop, position 6, is flat, is shown in FIG. 7

A rigid movable stop 6 is driven from a spring-loaded lifting lever 8 installed in the frame of the crossbars 2 and interconnected with the secret of the lock assembly 12, shown in Fig. 3.

The protection, made in the form of a rigid movable stop position 6, is spring-loaded and installed in the lock body 1, so that in the open or closed position of the lock, it does not interfere with the free movement of the rest of the lock mechanisms, not shown in the drawing.

The close-fitting plate 7 shown in FIG. 1 and FIG. 2.On an ongoing basis in various ways of fastening, welding, riveting, etc. position 6 is installed on top of a rigid movable stop, shown in FIG. 1 and FIG. 2.

Fitting plate 7, structurally installed on a rigid movable stop position 6.As an additional obstacle in case of criminal clogging of the crossbar frame 2, into the lock body, but in addition it is another obstacle in cases of criminal drilling or access from above to position 8 of the lifting lever, shown in fig. 1, fig. 3, fig. 3 and FIG. 6.

The tight-fitting plate 7, together with a rigid movable stop 6, performs the function of another additional point of support, since one side rests against the secret of the lock assembly 12, and the other side against the triple reinforcement of the rear of the lock case 1, while criminal pressure from the end is difficult the lock on the frame of the crossbars 2 is shown in Fig. 2A and FIG. 3.

Fitting plate 7, permanently mounted on a rigid movable stop position 6, is an integral part of it.

The lifting lever, position 8, is shown in FIG. 3 and FIG. 7 is intended for lifting the part of a rigid movable stop 6, for this purpose, a 45 ° bevel is provided on it along its entire length.

The lifting lever 8, installed on the transom frame 2, is permanently interconnected with the spring of the lifting lever 9 and in the initial position does not protrude beyond the overall dimensions of the transom beam SB, shown in Fig. 3.

At the beginning of the movement, the lifting lever 8, provided with a bevel of 45 °, extends under the rigid movable stop 6 and performs the initial lifting of one side of the rigid movable stop by 45 °, after which, due to the spring of the lifting lever 9, it leaves the zone of its action, i.e. e. returns to its original position.

The lift arm spring, item 9, is shown in FIG. 3. is designed to ensure the return of the lifting lever 8 to its place, is installed on the frame of the crossbars 2 and is permanently interconnected with the lifting lever 8, shown in FIG. 3.

Installation of a transom frame under a rigid movable stop.

The lifting lever 8 is installed on the ledger frame 2 and does not protrude beyond the overall dimensions of the ledger frame 2, shown in Fig. 3.

To install the frame of the crossbars 2, under the rigid movable stop 6, in certain places, on the parts, the lifting lever 8 and the rigid movable stop 6, 45 ° bevels are provided, which ensure the installation of one part on another, shown in Fig. 7, item 8 and item 6, are shown in FIG. 2B and 2C.

At the beginning of the movement produced by the secret of the lock assembly 12, the lifting lever 8 extends under the rigid movable stop 6 and makes the initial rise of one side of the rigid movable stop by 45 °, the beginning of the frame of the crossbars 2 is partially set under the raised rigid movable stop 6 - shown in fig. 2B, after the lifting lever 8, due to the spring of the lifting lever 9, leaves its zone of action, shown in FIG. 3.

With further movement of the lock assembled by the secret 12. advancing the frame of the crossbars 2, and, accordingly, pressing the hard movable stop 6 from below, at the critical point, the final lifting of the rigid movable stop 6 is completed and it is set to a horizontal position. Simultaneous advancement of the rest of the frame of the crossbars 2 under the rigid movable stop 6, makes it set in position above the frame of the crossbars 2, shown in Fig. 2B.

The final installation of the transom frame 2 takes place under the rigid movable stop 6 in the place strictly intended for this, i.e. after installing the two parts in place, they are both the part on the part in an even horizontal position, shown in Fig. 2B.

Cover item 11 shown in FIG. 4, is required for connection with the lock body 1.

All interactions of the internal mechanisms of the lock occur by transferring mechanical movement through the secret of the lock assembly 12, mounted on the cover 11.

On the cover 11, along its entire length, to strengthen the entire rear part of the lock body, an additional corner piece is installed, position 13, the method of installation is welding, riveting, shown in Fig. 4.

Corner position 13 shown in FIG. 4, is necessary to reinforce the entire rear of the lock case 1 and is installed on the cover, position 11.

Provided that the lock body 1 and the lid 11 on which it is installed are connected, the corner 13 is physically tightly installed with its entire length in the installation place provided for it, between the bent side of the 90 ° angle, the vertical pull of the lower 4 and the rear wall of the lock body 1, shown in fig. 2.

The corner 13 is connected to the cover 11, and being its integral part, installed on the cover 11, in the rear of the lock body 1, is an obstacle for criminal drilling from above, which occurs directly in the rear of the lock body 1.

When installed in the lock body 1, the cover 11, the corner 13 is connected to the cover 11, and being its integral part, installed with a minimum gap, abutting against the back wall of the lock body 1, is a reinforcement, shown in Fig. 2.

The lock assembly, item 12, is shown in FIG. 4.

All movements of the main mechanisms of the lock occur by transferring mechanical movement from the secret of the lock assembly 12 shown in FIG. 4.

The secret of the lock assembly 12, rigidly mounted on the cover 11 when the cover is installed on the lock body, interacts with the frame of the crossbars 2 through 2 pieces. leash 14 shown in FIG. 4, otherwise - leashes 2 pcs. position 14, installed on the secret of the lock assembly in the amount of 2 pieces, are intended to interact with the frame of the crossbars 2, for its horizontal movement.

But with the interaction of the two named mechanisms, with the criminal hammering of the frame of the crossbars 2, due to the constructive arrangement, the leashes are 2 pcs. position 14, they begin to perform the function of the next obstacle, shown in FIG. 2A.

Without criminally removing the secret of the lock assembly 12, it is impossible to push the frame of the crossbars 2 into the lock case 1, it is the leashes of 2 pieces that interfere. position 14 is shown in FIG. 2A.

The secret of the assembled lock 12 is another obstacle for the criminal hammering of the crossbar frame 2 into the lock case 1.

The first task set is technically achieved as follows;

When locking the lock, the frame of the crossbars 2 is set to the extended position, shown in Fig. 1.

In the lower rear part of the lock at the end point of movement, a rigid movable stop 6 is installed, at the end of the frame of the crossbars 2, shown in Fig. 2A.

The installation of a rigid movable stop, position 6, occurs at the stop between the frame of the crossbars 2 and the reinforced wall of the lock body 1, both parts are installed in series and abuts against the reinforced rear wall of the lock body, all details are shown in Fig. 2A.

Such an installation of two parts with the provided minimum gaps, between them, in series and at the stop, is a rigid blocking against any unauthorized hammering of the crossbar frame into the lock body, shown in Fig. 2A. and FIG. 3.

The posed second task is technically achieved as follows;

During the extension of the transom frame 2, the two vertical rods shown in pos. 3 and pos. 4, everything is shown in FIG. 2A, installed in the upper rear part of the lock body, under the corner 13;

- on one side, fit snugly against the secret of the lock assembly 12.

- on the other side, firmly rest against corner 13.

Both vertical rods located in the upper, rear part of the lock are structurally installed so that they perform the function of an independent additional movable protection and at the same time completely block access to the rigid movable stop 6 installed under them, shown in Fig. 2A.

Those. two practically independent independent mechanisms are installed, point-blank at three different heights, with five support points, shown in Fig. 2A.

One side;

- in the lower part of the lock, a rigid movable stop 6 is installed, at the stop, in the frame of the crossbars 2.

- in the lower part of the lock there is an emphasis with two leashes 14, in the frame of the crossbars 2.

- above the lower part, there is an emphasis on the tight-fitting plate 7, in the secret of the lock 12.

- in the upper part of the lock there is an emphasis with two vertical rods pos. 3 and pos. 4, a secret lock assembly 12.

On the second side, these two independent mechanisms in the rear of the lock abut against the created triple reinforcement of the lock body, all of the above is shown in Fig. 2A.

To the description of the protections in the lock, it is necessary to add the secret of the lock assembly 12, which, by its constructive arrangement, is always an obstacle to the criminal clogging of the bolt, even in cases of eliminating the first two created defenses.

The stated third task is technically achieved as follows;

Lock body 1, all-metal steel, rectangular, all 4 pcs. the corners of the lock body are welded, welding of all four corners is necessary to give greater strength to the entire lock body, in connection with the protections installed in it.

A corner 13 is installed on the cover 11, the cover 11 is installed on the lock body 1, then the lock is assembled and the corner 13 rests against the back wall of the lock body, which is already double reinforcement.

The very rear wall of the lock body 1, with the corner 13 installed to it and the bend angle of 90 °, of the vertical thrust of the lower 4, installed together with them, this is already a triple reinforcement for the lock body, is shown in Fig. 2A.

Three independent parts during the criminal hammering of the frame of the crossbars 2 will prevent the possibility of unbending the rear reinforced part of the lock case 1 with criminal blows, shown in Fig. 2A.

Thus, the created rigid double protection, consisting of the first two independent mechanisms, together with the triple reinforcement of the rear part of the lock body, practically creates a connection of the parts abutting against each other with a minimum gap between themselves and form a serious obstacle for the criminal hammering of the bolt frame into the lock body, all shown in FIG. 2A.

These three created defenses, not only, will greatly complicate the use of the criminal forceful method of driving the bolt, but the presence of one of them will fundamentally exclude even unauthorized access to the other two.

In case of criminal drilling;

- two protections in the upper and lower parts of the lock body are created in such a way that the upper protection completely blocks the criminal access to the lower protection installed under it, and creates a serious obstacle for criminal drilling;

- the necessary parts of the created protections are hardened by HRC 66.

- you will have to drill; through a metal door, cover 11, not shown in the drawing HRC 66 armor plate, vertical rods 2 pcs., position 3 and 4, plate fitting position 7 HRC 66, rigid movable stop position 6 HRC 66, or the secret of the lock assembly 12, to accurately get on the spring loaded lift arm 8 HRC 66, and criminally act on it.

Criminal actions, such as unauthorized drilling and driving a bolt into the lock body, are limited to a maximum of three protections.

The return of the crossbar frame 2 to its original position, pushed into the lock, is made by turning the lock secret assembly 12.

The return of the crossbar frame 2 to the position is pushed into the lock, this is how the lifting lever 8 installed in the crossbar frame 2 presses on the rigid movable stop position 6, and brings it to an elevated position at an angle, then the crossbar frame 2 is installed, under the raised rigid movable stop 6.

Not shown in the schematic drawing due to the simple obviousness of the ongoing process.

Innovations and differences from the prototype:

The first task has been completed - in the rear lower part of the lock, between the lock body 1 and the frame of the crossbars 2, a rigid movable stop 6 is created, shown in Fig. 2A.

The second task has been completed - in the rear upper part of the lock, between the lock assembly 12 and the lock body 1, an additional movable protection is created in the form of two vertical rods, shown in Fig. 2A, fig. 5 and FIG. 6.

Additional movable protection in the form of two vertical rods, installed in the rear upper part of the lock, completely blocks the very possibility of criminal access from above to the already created protection located in the rear lower part of the lock body, a rigid movable stop 6, shown in Fig. 2A, fig. 5 and FIG. 6.

The third task has been completed - in the rear of the lock case, from successively installed separate parts, such as the lower vertical rod 4 with a bend angle of 90 °, corner 13, and the rear wall of the lock case 1, a triple reinforcement is created.

Triple reinforcement of the rear part of the lock body 1, performs the function of reinforcement for the first two protections and the entire lock body 1, shown in Fig. 2A, and FIG. 5.

Thus, all the embedded parts are installed sequentially and together with the two protections form a single whole, given that their interaction occurs at different heights, the emphasis of different independent parts falls into reinforced places, the created protections can be called multi-level protection against criminal clogging of the bolt.

The use of two rigid independent emphasis with one of them performing the function of protecting the other, and the fact that each defense will have to be influenced separately, even this is psychologically a very serious obstacle to making a decision about illegal unauthorized actions, not to mention the technical difficulty of overcoming them ...

The technical result achieved in the invention: a new technical solution has been found for the interaction between all the main mechanisms of the lock with a newly created multi-level protection.

Unauthorized drilling became extremely difficult, it became practically impossible to drive a bolt into the lock case without unauthorized breaking of the lock secret and criminal elimination of the created multi-level protection.

All the proposed multilevel protections together form a new technical result.
