Secrecy block for four-turn slide-type locks

FIELD: ironmongery, particularly mortise or rim slide-type locks adapted to lock objects with high-strength doors.

SUBSTANCE: secrecy block includes bolt sides with depressions to cooperate with key bits and with slot for locking post receiving, as well as a set of semi-slides arranged in-between and supported by guiding posts. The semi-slides may move under the action of key and are spring-loaded by compression springs. The semi-slides have surfaces provided with slots for compression spring and guiding posts receiving. Block also has locking window with projections to cooperate with locking post, code combination to provide cooperation of half of semi-slides associated with key bits and notching to prevent another semi-slides half cooperation with the first one. Slots for compression spring receiving are identical with each other and have centers located in diagonal line of each semi-slide. Centers of guiding post receiving slots lie in another diagonal line. Locking window is made in transversal axis of semi-slide between different slot pairs. Locking extensions adapted to cooperate with locking post are created in one half of locking window passing into slot for locking post receiving at another window half. Code combination to cooperate with key bits is created in peripheral semi-slide edge under locking projections of locking window. Notching is created on opposite peripheral edge thereof and extends along diagonal line over locking post receiving slot. Said notching prevents contact of corresponding semi-slides with key bits from opposite secrecy block side, wherein each next semi-slide of the set is laid on previous one by the same side and turned through 180° in plane thereof.

EFFECT: improved secrecy, extended functional capabilities, simplified structure and decreased costs.

The invention relates to locks with plate delays moving when you turn the key and following the movement of the bolt, and can be used in the manufacture of locks in cut and patch versions, including for locking objects with doors high strength type of "safe door".

Known block of secret for lever locks (1)containing placed between the side bolt on the guide bars are spring-loaded in the direction of the key and movable on its pivot levers with locking Windows to interact with the locking bar, separated by a fixed plate mounted on the same guide columns.

Shut the window on all the levers are made identical, and the code combination of the secret made on the lateral faces of plates parallel to the direction of movement of the bolt, which allows podpruzhineny the whole package of plates the total compression spring and, consequently, increases the reliability of the castle, while significantly simplifying the design and reducing the complexity of the production.

This embodiment is very effective for the locks type SV-4. CL. 1 GOST 5089-97 secrecy to 500 variants, i.e. castles of mass demand, but a further increase in secrecy by increasing the number of levers in the set leads to an unjustified increase that the women of the castle, since the stationary plate between the levers do not participate in the formation of a code combination and are almost ballast.

Known in another part of the secret to sualnyh locks (2)containing a sidewall of the bolt with notches for engagement with beards key and slot for the locking bar, and placed between them on the hard-guides and additional guide bars set moving, turn the key and spring-loaded by compression springs, pausewang, on a plane which is made of different size slots for hard-to guides, and additional guide bars, shut the window with locking lugs for engagement with the locking bar and the code combination for interaction with beards key performed on one of the peripheral edges of palusalu parallel to the direction of movement of the bolt.

Shut the box with locking lugs for engagement with the locking bar, dispersed throughout its length, is made parallel to the transverse axis palusalu, slots for hard-guide columns and a spring compression performed on the shut window, slot for optional guide bar is made under closing the window, and the code combination punching to punch key provided on the peripheral edge of palusalu addressed to the keyhole and each subsequent plusvalia, laid on the flip side of the previous.

Such embodiment can significantly improve the security lock when identity with the equivalent of its thickness, to reduce the consumption of materials at identical secrecy, to reduce the complexity of Assembly and to improve the operating mode of the castle, however, determines the following disadvantages:

- the presence of two hard-guides and additional guide bars complicates the design and eliminates the possibility of another set of independent code combination for another set of keys on the other side of the block secret;

- execute on each palosverdes the compression springs of different size and placing them in hard-guides columns eliminates the possibility of podpruzhineny each spring the entire package pausewang in the set.

The stated object contains a sidewall of the bolt with notches for engagement with beards key and slot for the locking bar, and placed between them on the guide bars set moving, turn the key and spring-loaded by compression springs, pausewang, on the plane which made the slots for the compression spring, the grooves for the guide columns, shut the window ledges for engagement with locking bar code combination for interaction half pausewang set with beards key is punching, any contact with them the other half of plusvalia.

Open for compression springs are made identical, and their centers are located on the diagonal of each palusalu, the centers of the grooves for the guide bars are located on the other diagonal, and shut the window to interact with the locking bar is made on a transverse axis palusalu between pairs of opposite grooves, and the locking protrusions for engagement with the locking bar on one half of the gate window, rolling in the slot for the locking bar on the other half of the code combination for interaction with beards key performed on the peripheral edge of palusalu under locking tabs locking the window, and on the opposite peripheral edge above the slot for the locking bar is made punching precluding contact the respective pausewang with beards key from the opposite side of the block of secret, with each subsequent plusvalia in the set stacked on the previous the same side by 180 degrees in its plane.

Technical advantages of the declared object in comparison with the prototype are as follows:

- execution of the compression springs are identical and located diagonally on the field palusalu in conjunction with the presence and the diagonal arrangement of the slots is La guide bars provides the possibility of laying pausewang one another to the same side by 180 degrees in its plane, they move when you turn the key through one of the opposing parties and their simultaneous podpruzhineny to either side of the two springs;

- execution of locking the window in the transverse axis levers between pairs of opposite grooves and the location of the locking tabs on one half shut the window, rolling in the slot for the locking bar on the other half, in conjunction with the execution of the code combination on the peripheral edge of palusalu under locking tabs and punching to punch key on the opposite peripheral edge above the slot for the locking bar provides a set of at least two independent code combinations for two different sets of keys that interact with a block of secret on both sides;

- the possibility of laying pausewang one another to the same side by 180 degrees together with the presence of diagonally arranged grooves for the guide bars makes it unnecessary hard - guiding bars and marking pausewang on the reverse side.

The above-mentioned technical advantages of the claimed subject matter in comparison with the prototype allows to obtain the technical result consists in a significant increase of secrecy castles in the expansion of their functionality, in simplified and the design and reducing the cost of production.

In the accompanying drawings is illustrated a block of secret for chetyrehoborotnye lever locks, in which figure 1 shows a total view; figure 2 is a cross section along a - a; figure 3 - General view of the block of the secret to laid on the guide columns of the first palosverdes right propagate with an average position of the bolt in the lock body; figure 4 - the same, with the laid palosverdes left propacet and position of the bolt closed.

Block secret for chetyrehoborotnye lever locks contains the sidewall 1 of the bolt with the slots 2 and 3 to communicate with beards keys 4 and 5 and slot 6 for the locking bar 7, rigidly fixed to the hull parts of the castle (not shown). Between the side 1 on the guide bars 8 is a set of mobile turn-key 4 and 5, and spring-loaded by compression springs 9 pausewang 10 and 11, and palusalu 10 interact with key 5, and palusalu 11 laid on the previous the same side, but with a 180 degree turn in its plane and interact with key 4.

On the plane of each palusalu 10 and 11 are made identical grooves 12 for compression spring 9, the centers of which are located on the diagonal of palusalu, and on the other diagonal are the centers of the slots 13 for the guide bars 8, and the grooves 12 on plusvalia 10 and 11 in the set are the same and form a pass-through window to the Ruzhin compression 9, and the grooves 13 on the adjacent plusvalia superimposed on each of the opposite ends, forming a through hole for the guide bars 8.

On the transverse axis pausewang 10 and 11 between opposite pairs of grooves 12 and 13 is shut the window 14, one half of which is made of locking protrusions 15 for engagement with the locking bar 7, on the opposite side opposite to the locking protrusions made protivofiltrp 16 to communicate with him in case of emergency shut-down) pausewang, for example, if the unauthorised opening of the lock, and a through slot 17 between vystupamy and protivostoyanie for relative movement therein of the locking bar 7. On the other half of plusvalia shut the window 14 enters the slot 18 to the locking bar 7, and the locking protrusions 15 (drawing) on the peripheral edge of plusvalia 10 and 11 are executed code combination 19, interacting with key 5 and is converted into a code combination 20, interacting with key 4 with the subsequent reversal of the levers relative to the previous 180 degrees, and above the slot 18 of the stop window 14 made notching 21 precluding contact with beards keys 4 and 5 depending on the position of plusvalia in the set.

Thus, palusalu 10, mounted on the guide bars 8 and converted his code combination 19 to UCU 5, forming the right propacet pausewang with shared code combination for the key 5, and palusalu 11, deployed and stowed on palusalu 10 the same party on the same guide bars 8, form left propacet with shared code combination for the key 4, wherein each pair of plusvalia 10 and 11 forms a total shut the box with a full set of locking tabs 15, protivovesom 16 and through the slot 17 to move the block secretion relative to the locking bar 7, the total end-to-end window for the compression spring 9 and the common through hole for the guide bars 8, but different, independent from friend code combination 19 and 20 for 5 keys and 4, respectively.

When you turn the key 4 in a clockwise direction (figure 1) palusalu 11, separated by one plusvalue 10, interacting with its code combination 20 with the corresponding bit of the key 4, the guide bars 8 are synchronously moved downward (in the drawing), whereby both of the spring 9 under the influence of window 12 is compressed, resting in the bottom window 12 pausewang 10, since the latter is fixed by the slot 18 on the locking bar 7 and the guide bars 8, which excludes the possibility of their accidental displacement from any effects, including turn-key 4.

When the punch key 4 to 60 degrees relative to the direction p. the motion of the bolt through the slot 17 of the left propacet pausewang 11 is combined with a slot 6 side 1 bolt, opening the possibility of its movement relative to the locking bar 7 upon further rotation of the key 4 to 120 degrees, then when the rest of the rotation to 180 degrees palusalu 11 under the influence of spring 9 to move upward until it stops and their projections 15 is fixed with the bolt in the first intermediate position.

Extension bolt on the value of the next step is carried out similarly with the participation of the second section of code combinations 20 and second recesses 2 on the side 1 bolt, when in the middle position (figure 3) bolt securely locking protrusions 15 pausewang 11 to the left (in the drawing) and pausewang 10 on the right. In this position of the latch (3) both keyhole for keys 4 and 5 remain open.

Extension bolt on the third and fourth steps are performed with the same operations to be performed only key 5 on the other side of the block of the secret, and the key interacts with plusvalue 10 and is rotated counterclockwise, and the keyhole for the key 4 becomes blocked, side 1 bolt.

Movement of the latch for opening the lock is in the reverse order, after its full travel on four steps (figure 1) becomes blocked the keyhole for the key 5.
