RU2310052C2 - Secrecy block for four-turn slide-type locks - Google Patents

Abstract

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.

Description

The invention relates to locks with plate delays, moving when the key is turned and following the movement of the deadbolt, and can be used in the manufacture of locks in mortise and surface versions, including for locking objects with high-strength doors such as “safe doors”.

There is a known secret block for level locks (1), containing spring-loaded in the direction of the key located between the sides of the bolt on the guide columns and levers with lock windows for interacting with the locking column, separated by fixed plates mounted on the same guide columns.

The locking windows on all the levers are identical, and the secret code combination is made on the lateral faces of the levers parallel to the direction of movement of the bolt, which makes it possible to spring the entire levers package with a common compression spring and, therefore, increases the reliability of the lock while significantly simplifying the design and reducing the complexity of production.

This design is very effective for locks type ZV8-4. Cl. 1 GOST 5089-97 with secrecy of up to 500 options, i.e. locks of mass demand, but a further increase in secrecy by increasing the number of levers in the set leads to an unjustified increase in the thickness of the castle, because the fixed plates between the levers do not participate in the formation of the code combination and are practically ballast.

Another block of secret for suval locks is known (2), containing the sides of the deadbolt with recesses for interacting with key barbs and a slot for the locking column, as well as a set of semi-lever blocks movable from turning the key and spring-loaded compression springs placed between them on the stop guides and the additional guide columns. , on the plane of which different-sized grooves are made for the stop-guides and the additional guide posts, a locking window with locking tabs for interacting with the locking column and the code a different combination for interaction with key barbs made on one of the peripheral edges of a half-shaft, parallel to the direction of movement of the bolt.

The locking window with locking tabs for interacting with the locking column dispersed along its entire length is parallel to the transverse axis of the half shaft, grooves for the supporting guide columns and compression springs are made above the locking window, the groove for the additional guide column is made under the locking window, and the code combination and the cuts for the key barbs are made through one on the peripheral edge of the half-shaft, facing the keyhole, and each subsequent half-shaft, laid on the previous reverse side.

This design allows you to significantly increase the security of the castle with the identity with an analog of its thickness, reduce material consumption with identical secrecy, reduce the complexity of the assembly and improve the operation of the castle, however, it determines the following disadvantages:

- the presence of two thrust guides and an additional guide column complicates the design and excludes the possibility of dialing another independent code combination for another set of keys on the other side of the secret block;

- the execution on each hemisphere of windows for compression springs is different in size and the placement of stop-guide columns in them eliminates the possibility of springing of the entire package of half-collapses in the set with each spring.

The claimed object contains the sides of the deadbolt with recesses for interacting with the key barrels and a slot for the locking column, as well as a set of half-movable semi-suvalds movable from turning the key and spring-loaded compression springs located on them between the guide columns and on the plane of which grooves for compression springs and grooves for guide columns , a locking window with protrusions for interacting with the locking column, a code combination for the interaction of half half-set in the set with key barbs and a notch excluding contact with them the other half hemisphere.

The windows for the compression springs are identical, and their centers are located on the diagonal of each hemisphere, the centers of the grooves for the guide columns are located on the other diagonal, and the locking window for interacting with the locking column is made on the transverse axis of the semivalike between pairs of opposite grooves, and the locking protrusions for interacting with a locking column is made on one half of the locking window, turning into a slot for the locking column on the other half, a code combination for interacting with the barbs The cha is made on the peripheral edge of the half-shaft under the locking protrusions of the locking window, and on the opposite peripheral edge above the slot for the locking column, a notch is made, excluding the contact of the corresponding half-banks with the barbs of the key on the opposite side of the secret block, with each subsequent half-shaft in the set laid on the previous one of the same side with a 180 degree turn in its plane.

The technical advantages of the claimed object compared to the prototype are as follows:

- the implementation of windows for compression springs identical and diagonally located on the hemisphere field in conjunction with the presence and diagonal arrangement of grooves for the guide columns provides the possibility of stacking the semispals on the same side with a 180-degree turn in its plane, moving them when the key is turned through one in opposite directions and their simultaneous springing to either side with both springs;

- the implementation of the locking window on the transverse axis of the level between the pairs of opposite grooves and the location of the locking protrusions on one half of the locking window, turning into a slot for the locking column on the other half, in conjunction with the execution of the code combination on the peripheral edge of the half-mat under the locking protrusions and the notch for barbs key on the opposite peripheral edge above the slot for the locking column provides the ability to set at least two independent code combinations for two different x keys sets interacting with the secret unit on both sides thereof;

- the possibility of stacking the half-dumps on the same side with a 180-degree turn, in combination with the presence of diagonally located grooves for the guide posts, makes stubbornly unnecessary - guide posts and marking of the half-dumps on the reverse side.

The combination of these technical advantages of the claimed object compared with the prototype allows to obtain a technical result, which consists in a significant increase in the secrecy of locks, in expanding their functionality, in simplifying the design and reducing the cost of production.

The drawings illustrate the secret block for four-turn level locks, where in Fig.1 shows its General view; figure 2 is a cross section along aa; figure 3 is a General view of a block of secret with laid on the guide columns of the first half-dozen of the right half-packet with the middle position of the bolt in the lock case; figure 4 is the same, with the left half-bag half-packed and the deadbolt position “closed”.

The secret block for four-turn level locks contains the sides of the bolt 1 with recesses 2 and 3 for interacting with the beards of the keys 4 and 5 and the slot 6 for the locking column 7, rigidly fixed in the case details of the lock (not shown in the drawings). Between the sidewalls 1, on the guide posts 8, a set of keys 4 and 5, which are movable from turning and spring-loaded with compression springs 9, are mounted on the half-jacks 10 and 11, the half-jacks 10 interacting with the key 5, and the half-jacks 11 are laid on the previous ones on the same side, but with a 180 degree turn in their plane and interact with the key 4.

On the plane of each half-shaft 10 and 11, identical grooves 12 are made for compression springs 9, the centers of which are located on the diagonal of the half-shaft, and on the other diagonal, the centers of the grooves 13 for the guide posts 8 are located, while the grooves 12 on the half-wheels 10 and 11 in the set coincide and form through windows for compression springs 9, and grooves 13 on adjacent semi-levers are superimposed on each other with opposite ends, forming through holes for guide columns 8.

A locking window 14 is made on the transverse axis of the semisuvald 10 and 11 between pairs of opposite grooves 12 and 13, on one half of which locking protrusions 15 are made for interacting with the locking column 7, on the opposite side opposite the locking protrusions 16 are made for interacting with it in case of over-lifting a semi-suvald, for example, during unauthorized opening of the lock, and a through slot 17 between hollows and counter-protrusions for the relative movement of the locking column 7 in it. On the other half, the half-suvald is locked The second window 14 goes into the slot 18 for the locking column 7, and under the locking protrusions 15 (according to the drawing), a code combination 19 is made on the peripheral edge of the semi-levers 10 and 11, interacting with the key 5 and turning into a code combination 20, interacting with the key 4 when turning subsequent suvaldah relative to the previous one by 180 degrees, and a notch 21 is made above the slot 18 of the locking window 14, excluding contact with the beards of keys 4 and 5, depending on the position of the half-suvalds in the set.

Thus, the half-boxes 10 are mounted on the guide posts 8 and turned with their code combination 19 to the key 5, forming the right half-package with half the general code combination for the key 5, and the half-boxes 11, when deployed and laid on the half-boxes 10 on the same side, on the same side guide columns 8, form a left half-packet with a common code combination for key 4, while each pair of half-levers 10 and 11 forms a common locking window with a full set of locking protrusions 15, opposed protrusions 16 and a through slot 17 for moving the block Single secret latch post 7 with respect to common through windows to compress spring 9 and common through holes for guide columns 8 but different, independent from each other codewords 19 and 20 for the keys 4 and 5, respectively.

When the key 4 is turned clockwise (Fig. 1), the half-gears 11, separated by one half-gears 10, interacting with their code combination 20 with the corresponding beard of the key 4, synchronously move downward along the guide columns 8 (according to the drawing), as a result of which both springs 9 under the influence of the windows 12 are compressed, abutting against the lower end of the windows 12 half-suvald 10, because the latter are fixed by a slot 18 on the locking column 7 and the guide columns 8, which eliminates the possibility of their accidental movement from any influences, including from turning the key 4.

When the wedges of the key 4 to the position of 60 degrees relative to the direction of movement of the bolt, the through slot 17 of the left half-package half-half 11 is combined with the slot 6 of the sides 1 of the bolt, opening up the possibility of its movement relative to the locking column 7 with a further turn of the key 4 to 120 degrees, after which the rest of the turn up to 180 degrees hemisphere 11 under the influence of the springs 9 rise up to the stop and with their protrusions 15 fix the bolt in the first intermediate position.

The bolt is extended by the value of the next step in the same way with the participation of the second section of the code combination 20 and the second recess 2 on the sides of the bolt 1, while in the middle position (Fig. 3) the bolt is securely fixed by the locking protrusions 15 half-lever 11 on the left (according to the drawing) and half-lever 10 - on right. In this deadbolt position (FIG. 3), both keyholes for keys 4 and 5 remain open.

The bolt is advanced to the third and fourth steps by performing the same operations only with the key 5 on the other side of the secret block, the key interacting with the half-boxes 10 and turning counterclockwise, and the keyhole for the key 4 becomes blocked by the sides of the bolt 1.

The movement of the deadbolt to open the lock is performed in the reverse order, and after its complete movement by four steps (Fig. 1), the keyhole for key 5 becomes blocked.
