Description

Technical field

The present invention relates to a level lock with an S-level lock with a high-security mechanism for entrance metal doors of various weights, types and configurations, in particular of a type that can be manipulated with double-bit keys.

Prior art

The locks associated with the double-barred keys consist of a main box body provided with a socket (which is located essentially in the transverse direction) suitable for inserting the key. The prior art is resistant to breaking the lock EP 0903455 A2, E05B 21/00, publ. 03.24.1999, the key, being inserted, is located so that its code part is aligned with the set of code plates - the suvald, which can perform a partial translational movement along given directions. The rotation of the key in the well causes the movement of the plates (suvald), which is consistent with the disengagement of the rack (which in the normal position engages with the plates), such a rail, thus, can translate by rotating the key in the well. The bolts are firmly connected to the front of the rail, while the translational movement of the rail causes the bolts to extend from the end of the lock with subsequent stable engagement of the bolts in the slots of the jamb, ensuring the correct closure of the door in which the lock is installed.

However, this type of lock is prone to tampering with a type commonly known as breaking the lock. Methods of breaking the lock involve the use of special tools that are inserted into the hole designed to insert the key: using these tools, by holding the rail with a load in the direction that corresponds to the retraction of the bolts (bolts), the cracker can individually raise the plates until the rail will be released, while the rail is retracted due to the applied mechanical load. Although these hacking methods are quite complex, they have a clearly high success rate and therefore make this lock essentially unreliable.

Also known from the prior art is a tamper-resistant lock RU 2461692 C2, E05B 21/00, publ. 09/20/2012, comprising a box-shaped housing for arranging a plurality of figured plates provided with a corresponding part that is suitable for disengaged engagement with a corresponding portion of the rail. The lath can carry out translational motion and carries bolts (bolts) at its free end, which can be retracted as a whole with the specified lath. The plates are able to carry out vertical translational movement through the action of the key and release, when they are raised, the translational movement of the rack and bolt (bolts) for their retraction and extension.

The plates contain sections provided with sockets that are aligned with the proximal protrusions, which are configured essentially in accordance with the configuration of these sockets. The plates are able to oscillate around a guide pin rigidly connected to the box body. The lock also contains elastic means located between the fixed stop and the site, which is located near the socket. The elastic means are formed by an axial spring, which is located inside the element, which is rigidly connected to the box-shaped body. The element contains a protrusion, is rigidly connected to the box-shaped body and is adapted to locate the axial spring. This type of lock provides a good level of protection against hacking actions of a destructive type, but its mechanism is not reliable enough for prolonged use.

Also known from the prior art is the padlock lock RU 2461692 C2, E05B 21/00, publ. 09/20/2012, comprising a housing, a cover, a bolt with a shank, a set of spring-loaded levers, a locking bolt for each half turn of the key, a protective gear sleeve with a hole for the key, while the leash on the shank of the bolt is inserted into

a special spiral groove of the disk mounted on the rack with the possibility of rotation coupled to the protective gear sleeve with the possibility of transferring the rotational movement of the key inserted into the protective gear sleeve to the disk and converting the rotational movement of the disk into intermittent translational movement of the bolt. This type of lock also provides a good level of protection against hacking actions of a destructive type, however, the design of its mechanism is complex and, as a result, is not reliable enough for prolonged use. This level lock is selected as a prototype.

The objective to which the claimed invention is directed is to simplify the design of the lock, increase the reliability of the level mechanism and increase the resistance to cracking, which are known in the field of opening locks.

SUMMARY OF THE INVENTION

The technical result of the claimed invention is to increase the reliability of the levers mechanism by eliminating the unstable interaction of the shank and levers when the deadbolt deviates under the action of the key, increasing the burglar resistance of the levers mechanism with S-levers and simplifying the design of the lock.

This technical result, as well as other technical results that will become more apparent in the future, are achieved using the present claimed invention.

The lock contains a housing having a cover with a bent edge with holes for the deadbolts, a latch, longitudinal traction of the castle, made with the possibility of movement, levers and bracket arm. The lever arm is fixed to the bolt of the lock with set screws, which at the same time allow the longitudinal pull rods of the lock to be moved and the hinge to transmit the force of the key to the latch. The synchronous secret mechanism is made of levers, while the levers are made in an S-shape with an upper and lower position relative to the keyhole. The lock levers cover covers the upper and lower sets of S-levers, mounted on the levers with screws, serves as a support, which is turned at an angle, for the torsion springs of the upper levers, and is the guide plane for the three shank racks mounted on the gear bolt.

Toothed grooves are located on S-shaped levers. The upper and lower sets of S-shaped levers form a synchronous mechanism for collecting secrets with a lock key, while moving the lock bolt, the upper and lower sets levers are mounted on truncated racks with a protection tooth, the levers secrets interact with three shank racks mounted on the lock bolt. The latch is mounted on two support posts, while the latch extends under the action of a compression spring, the edge of the housing serves as a spring support. The compression spring of the latch is configured to return the hinges to their original position within the groove on the hinge. The cam is controlled by a halyard handle, while a torsion spring is fixed to it, which is configured to return the cam to its original position. Three shank racks are designed to operate in four half turns of the key, on the first two half turns one rack of the shank of the upper set works, in the next two half turns the other stand of the upper set and the stand of the lower set of S-shaped levers simultaneously. The housing has two hexagonal racks for attaching the faceplate.

The lock mechanism device comprises at least one levers, a shank and shank racks. At least one suvald is made S-shaped with the possibility of interaction with at least two racks of the shank. At least one S-shaped leopard is made with serrated grooves located inside the guide groove of the S-shaped leopard on one of its sides. The S-shape Suvald Stand contains a tooth. The rack is intended for fastening S-shaped levers and at the same time is anti-burglar protection, the touch points of the racks and at least one S-shaped levers are located on one side of the rack circumference, and the tooth common to all S-shaped levers is opposite . The torsion spring is configured to simultaneously implement at least one S-shaped levers of two directions of movement - down and sideways, the upper and lower sets of S-shaped levers. The torsion spring support is deployed in relation to one of the sets of S-shaped levers at an angle. The torsion spring support is deployed in relation to the set of levers at an angle of 3-7 degrees. The serrated grooves on the S-shaped gauge are located inside the guide groove of the S-shaped gauge, on one of its sides. The lock mechanism device may contain 2-4 shank posts on one bolt.

The implementation of the invention.

The lock is designed as a high-security mechanism for entrance metal doors of various weights, types and configurations of FIG. 1. A lateral bolt pattern and a double-beaded brass key corresponding to this pattern are selected in the lock. The device of the lock mechanism allows you to control the latch as a halyard handle on both sides of the door, and to open the latch with the key of the lock. The latch is locked when the lock bolts are fully extended. The lock uses a synchronized mechanism for dialing a level with a double-wrench, each beard. The privacy mechanism uses 12 S-shaped levers with four half turns of the key. The use of secret protection prevents criminal non-destructive methods of opening the lock.

In FIG. 4 shows the internal structure of the lock mechanism. The lateral arrangement of the deadbolt (3) determines both the operation of the latch and the movement of the longitudinal rods (7) of the lock. The bracket-lever (4) is fastened to the bolt (3) using the set screws (14), which allows the bracket-lever to have a degree of freedom in the horizontal and vertical directions. In the bracket there is a groove under the rack. The stand is mounted on the leveling cover (11) and is used as an additional support for the bracket. Two racks are installed on the bracket (4), one for moving the longitudinal rods (7), a hinge (6) is attached to the second, distributing the force when turning the key (17) to open the latch (11) through additional hinges (15) (16), fixed on the lock cover (2).

The lock key (17) has symmetrical pushing teeth on two barbs that interact with the hinge (6) and the gear rack (10) on the bolt (3). The hinge (6) moves together with the bracket and the bolt at the same time and interacts with the key only in the open state of the lock. The cover of the levers (5) covers the upper and lower sets of levers (19) (20) from mechanical stress and is fixed to the racks of the levers with screws. The cover of the levers also serves as a support, deployed at an angle of 3-7 degrees, for torsion springs (8) of the upper set of levers (19) and is a guide plane for the three legs of the shank of FIG. 5 (18) fixed to the gear rack of the bolt (3). The castle uses two sets of S-shaped levers with an upper (19) (six pieces) and a lower (20) (six pieces) arrangement relative to the keyhole. Toothed grooves (21) of secretion protection are located on the S-shaped suvald. The upper and lower sets of the S-shaped levers of FIG. 5 (19) (20) form a synchronous mechanism for collecting secrets with the key (17) of the lock, while moving the bolt (3) of the lock. S-shaped levers of the upper and lower set are mounted on truncated racks (22) (23) with a protection tooth (24) of FIG. 7, the racks themselves are riveted in the housing (1). The secrets of the suvald interact with the three legs of the shank of FIG. 5 (18) mounted on the bolt of the castle.

The latch (11) of the lock is mounted on two support posts with quick-release washers, the latch mechanism device allows you to change the position of the latch bolt. The latch extends under the action of a compression spring, the spring side is supported by the edge of the housing (1). Also, the compression spring of the latch returns the hinges (16) (15) (6) to their original position within the groove on the hinge (15). The cam (12), controlled by the halyard handle, pushes the latch into the inside of the lock body, the torsion spring (13), mounted on the cam (12), returns it to its original position. In FIG. 4, the lock mechanism is shown in the closed position, the protrusion on the bolt (3) blocks the latch from movement. In the selected lock scheme, three shank posts (18) are used, working in four half turns of the key. When closing the lock on the first two half-turns, one rack of the shank of the upper set works, in the next two half-turns another stand of the upper set and the lower set of the suvald work simultaneously. Two hexagonal posts are installed in the lock case for fastening the front plate. The location of the three shank racks (18) and two sets of S-shaped levers upper (19) and lower (20), explaining the operation of the synchronous lock mechanism, is shown in FIG. 5.

The lock case is intended for lock mechanisms of various types and devices. The housing consists of two parts of FIG. 2, on one of the faces arranged connection of parts "in the lock", which gives additional strength characteristics to the housing of this design. The cover (2) is made with a side face, on the verge of an opening under the crossbar. The cover (2), after assembling the lock mechanism, is pushed onto the housing (1) until the “lock” of the cover and the housing is connected. The advantage of such a lock case is the possibility of assembling the lock mechanism without taking into account the length of the bolts and the dimensions of the lock case are smaller, as well as the possibility of adjusting the position of the cover. The sweep of the body and cover has the same width, which allows you to get body parts from a workpiece of the same width.

S-shaped levers are an element of the levers of any type of lock mechanism. S-shaped suvald allows creating mechanisms of “secrecy” of level locks with load characteristics of ordinary levers. In FIG. Figure 8 shows the types of S-shaped suvald for four half-turns of the secrecy mechanism of the level lock and S / 2-shaped suvald, working with two half-turns of the key, as well as with one half-turn. The “secret” serves as the elements of the S-shaped levers forming the form, divided into two identical parts located one above the other, two grooves for two truncated racks of FIG. 7 (22) and the profile shape of the working surface located at the bottom of the groove for the Suvald strut interacting with the double-wrench key (17). The advantage of using parts of the “secret” is the short length.

It is known that the bolt under the action of the key bends up and down, this leads to unstable interaction between the shank and the levers. To ensure that such deviations do not interfere with the operation of the lock mechanism, design changes are required to stabilize the movement of the bolt and shank strut. In the S-shaped suvald, two “short secrets” located symmetrically with respect to the symmetry axis of the S-shaped suvald, passing through the centers of the two grooves, with such a length of deflection of the bolt (3) and the shank (18) are insignificant, which allows not to use designs with stabilization of the deadbolt and the strut of the shank when moving. The shape of the levers allows you to develop designs of level locks with smaller dimensions, which significantly reduces the weight of the castle.

A distinctive feature of S-shaped levers is its secret operation with two shank posts (18), which increases the burglar resistance of the mechanism (drilling, destructive and non-destructive methods ...) and ensures the principle of operation of four half-turns and two half-turns of the level lock scheme. The principle of operation of two shank racks in one “secret” for four half-turns of the key is shown in FIG. 12, the diagram shows the stepwise movement of the lock bolt and the location of the shank racks at this moment. Step 2 according to the diagram shows the simultaneous operation of two shank racks, limiting the bolt in motion from two sides. Using S-shaped levers, it is possible to obtain synchronous levers with an upper set (19) and a lower set (20) of the arrangement of the levers of FIG. 5. Considering the possibility of S-shaped levers to work in synchronous secret mechanisms in locks, it is possible to use from 1 to 4 shank racks (18) on one bolt (3).

To ensure the operation of the lock on the S-shaped suvald, both a torsion spring (8) and a compression spring are fixed. The used schemes of the mechanism of the “secret” of level locks are shown in FIG. 9, FIG. 10, FIG. 11, with the number of shank racks for each position. In the diagrams of FIG. Figure 9 shows the location of S-shaped levers for both synchronous (upper and lower set) lock mechanisms, as well as for ordinary applications in levers with four half-turns of a key. In FIG. 10, FIG. 11 shows diagrams with two half turns of the key in the lock mechanism, also in FIG. 11 shows diagrams for one half turn of a key in a lock.

The “secret” protection device refers to level, safe and door locks of any type, which allows to obtain a high degree of security against opening the lock by non-destructive means and methods. Several protections of this kind of action are known, for example, a swinging leopard, a swinging rack of a leopard and an ALPS (All Levers Protection System) protection system.

The mechanism of action of the protection of FIG. 6 is based on the use of the properties of a torsion spring (8), fixed at one end on an S-shaped levers (19), and rests on the spring support (5) with the other. The torsion spring support (5) is deployed in relation to the set of levers at an angle of 3-7 degrees, which contributes to the direction of action of the force of the levers springs. The shape of the spring (8) distributes the force of the spring in such a way that part of it is directed along the levers, and the other part presses the levers against the rack levers (22) from one side to the touch points (25). S-shaped levers remain in the pressed state constantly, which does not interfere with the operation of the lock mechanism. In the lock, a rack of suvald (22) with a tooth (24) of FIG. 6. The stand is designed to mount the levers and at the same time is an anti-burglar protection of the lock. The touch points (25) of the rack (22) and the levers (19) are located on one side of the circumference of the rack, and the common tooth for all levers (24) is on the opposite. A similar tooth (24) can be made of any shape (triangle, square, etc.). In FIG. 7 shows a truncated rack of levers with an anti-burglar tooth. The serrated grooves of FIG. 6 (21) on the leopard are located inside the guide groove of the leopard, on one of its sides. The shape of the serrated grooves (21) may be of a different shape (triangular, square, trapezoidal).

If you act on the bolt (3) of the castle by criminal non-destructive methods of FIG. 6a, the protection works as follows, the shank stand (18) presses on the levers (19), the S-shaped levers bow when lifted and fall in the serrated grooves (21) on the tooth common to all levers (24) on the levers (22). This protection action does not allow to determine the true code slots of the “secret” on the levers. To return the protection to its original state, the key (17) of the lock in the opposite direction is used. In protection, toothed grooves (21) on the levers, a rack of levers (22) with a single tooth (24), a torsion spring (8) are used, a compression spring, levers (19) can be used.

The use of protection is possible on levers of any type and any shape using a torsion spring or compression spring. The device uses a common guide flat spring to stabilize the operation of the lock lever kit.
