Description

The invention relates to ring locks, consisting of two closed half-rings.

In the proposed lock, the half-rings are closed between themselves with the help of latches and additional locking half-rings. In order to place the latter at a certain angle, the numbers on the lock body are packed against the one with the known password and the aforementioned additional half rings are installed by means of divisions applied to them.

In FIG. 1 depicts the external appearance of two half-rings of a wall of a secret lock; FIG. 2, 2а, 26, 2в - its transverse sections along AB; FIG. 3 - external view of one pair of internal additional stop half-rings; FIG. 4 - cuts on VG of a set of internal half-rings; FIG. 5 - external view of a closed lock; FIG. 6 is a section through its center plane according to the DE in FIG. five; FIG. 7 is an enlarged view of the section of the lock according to CL of FIG. 5 with a set of stop semirings inserted into it; FIG. 8 - side view of the assembled lock; FIG. 9 is a section along MP of FIG. eight; FIG. 10 is a detail of FIG. 9 on a larger scale; FIG. 11-button and FIG. 12 is a schematic diagram of a door lock device for putting the lock flush with the lock.

The proposed secret lock ring consists of two massive metal half rings / (Fig. 1) of circular, square or other cross section, having internal slots 2 at their ends (Figs 9 and 10).

In one of the sockets of each half-ring a spring hook 5 is fixed in the form of a frame, a plate with a tooth, etc., and in the other socket there is a special protrusion - a thorn 4 (Fig. 9 and 10). When the rings are joined by the ends, the spring hooks, provided that they are pressed on top, engage the pins and thereby close the lock. On the outer side of the rim of the lock, a semi-secret channel 5 (Fig. 2 and 6) is made of a T-shaped or other shaped section (for example, in the form of a dovetail), in which a set of flat locking semirings 6 is placed (Fig. 3, 4 and 7).

Each pair of half-rings 6 in their connection represents a solid flat ring that can only rotate round the channel of the castle. Semi-rings 6 also have a shaped section, which is ensured by their falling out of the lock channel (into which they can be moved only if the lock is open).

At the ends, from the inner edge of each half-ring, a cutout 7 is made (Figs. 3, 9, 10) so that when a pair of these half-rings are joined, there are two sockets on the inside of the ring.

According to the shape of this socket, on the spring hook, there is a latch 5 above (fig. 9 and 10), which can be placed in a socket formed not by one or several rings, but only by the whole set of locking rings, since the width of the latch 8 is equal to the width of the sole of the whole set of locking rings. When connecting the assembled half-rings with the ends and turning one, several or all of the rings in channel 5, the lock will be in the closed position. To open it and separate the half-rings, you need to turn all the rings so that all their sockets fall over the latch 8, then the spring of the locking hook will lift it upwards and the lock will open.

The outer surface of massive semirings has equal divisions 2, each of which has its own number or letter. The surface of the castle can be trimmed in the form of lobules, masking the junction of semirings, i.e., in the form of worm cascade or other joints. In the outer edges of the locking rings, sockets 9 (Figs. 3, 9, 10) are arranged at the same distance from each other as in the massive half rings, so that these half rings can be set in such a way. that all their lobules will coincide radially. A button 10 (FIGS. 11 and 10) is inserted into one of the sockets of each pair of half-rings, which serves to rotate the locking ring and set it against the desired division of the massive ring. The JO button can be inserted into any of the jacks of the ring and removed from it only when disassembling the lock.

If the lock and locking rings have, for example, 24 divisions (12 in each half-ring) and the set of rings consists of four pieces, then the lock will have 20736 combinations, of which only one will cause the lock to open. With five locking rings, the number of combinations will be

already 248832. In general, the number of combinations will depend on the number of divisions on the rings and the number of locking rings in the set. The secrecy of the castle can be varied at its discretion by rearranging the buttons in the locking rings. To open the lock; its owner remains to remember only the number, each digit of which will show, against which division the first, second, and so on buttons of the locking rings will be set.

Thus, with a certain device of the locking device, for example, in the form of a cut button with a neck (Fig. 12), fitted over the lock, so that the latter would sink into the neck of the lock and that the outer rim of the lock would be flush with the button, the lock cannot be opened by unauthorized persons.

The lock on the inside does not necessarily have to have a regular round shape, but can have any other shape, for example, in the form of a square, a truncated circle (as shown in Fig. 9), and so on; under this condition, the lock will not turn in constipation, which sometimes represents great convenience.

The subject matter of the invention.

Claims (3)

1. A new secret ring lock with a housing composed of two half-rings connected to each other, characterized in that, for the purpose of opening; half-rings of the lock case, additional locking half-rings 6, which are rotatably fixed on it and provided with notches 7, are installed in a definite position by means of divisions 12 applied on them. 2. In the lock according to claim 1, the use of rotatable spring-loaded latches 5, which are closed by rotary locking semirings 6 during the rotation of the latter. 3. The form of the lock according to claim 1, characterized in that the locking semirings 6 have a shaped section in order to prevent them falling out of the guide channel 5.
