The invention relates to locks, and particularly to mortise locks with push keys, and can be used in apartments and offices.

The famous castle on the patent of Russian Federation №2229575 (publ. 27.05.2004). This lock includes a housing with a cover and a rotary disk, which is made coaxial holes and installed freely moving the locking pins, the latch-bolt mechanism for moving the bolt comprising an external handle, firmly planted on the shaft with the clamp, a piston freely mounted on the shaft of the handle, which interacts with the locking pins and the shaft collar, socket wrench, made with holes arranged coaxially with the axes of the locking pins, and placed in the gap formed by the ends of the handle and the housing, while the lock is further provided with an inner handle which made the grooves and mounted rollers, one roller for engagement with the bolt, the other for engagement with a rotary drive, which also made a groove in the roller, in addition to the external handle shaft freely installed protective washer, positioning the locking pins against the mechanical key, and the locking pins are made of more than two separable parts, one of these parts is made in the form of a stepped shaft, and the other is a pin freely, with guaranteed clearance moving in the cylinder, and the holes in ortonovo key are recorded in a code position stops.

This castle, like all current locks, has the disadvantage that its secret part is rigidly connected with the entire lock mechanism and cannot be instantly without disassembly of the lock replaced by another after its release. As a result of this potential attacker knows what is and how it works, and therefore can open any lock, making him the pick falsified key, etc. to Replace the secret part of the castle is, as a rule, when it is broken or you have any concerns, to exclude any possibility of tampering key and unauthorized opening of the lock. Imagine that your castle has not one, but several secret parts, which are used interchangeably at your discretion after each opening of the castle, and locked rigidly fixed in the castle. In addition they possess a different secret design features. This allows us to obtain the castle, which is open criminal is almost impossible, because it is not known what the secret is and how it works. Thus, significantly increased criminal resistance of the castle, which is the basis of any such products.

The closest in technical essence is the castle on the patent of Russian Federation №2464399 (publ. 20.10.2012), comprising a housing with a lid, the latch-bolt mechanism moved the I bolt in the form of a sleeve, offline secret block in which you installed the locking pins, and the socket wrench with code lock. In the casing axial hole freely moving the locking pins. The mechanism for moving the bolt interacts with the locking pins. The socket wrench is made with holes arranged coaxially with the axes of the locking pins. In the holes of the mechanical key are recorded in a code position stops. Secret block when the lock bolt is fixed in the housing, and in the unlocked condition of the lessons, opening up access to the bolt or the mechanism of its movement. This castle is interesting because in the open state secret can be extracted from the castle and replaced with similar. This allows you to change the basis of the castle, leaving unchanged its kinematics. This ability greatly increases criminal resistance of the castle and its secrecy, since the replacement of a secret unit that has its own code, may be performed every time it is opened.

The disadvantage of this lock is the inconvenience in its use, because each time you unlock it you need to extract the secret block and move the bolt opening or closing the lock directly by hand, as the latch.

The invention solves the problem of the increase will consume Liska properties of the castle while maintaining the highest level of security properties by creating a secret part of the castle, which interacts with the power part of it allowing comfortable use of the product and, if necessary instantly replace secret part of her kind.

To achieve this, the technical result in the lock, comprising a housing with a cover, a bolt, a secret unit code key, the body is equipped with the fixing axis and a spring-loaded detent in the casing and radial offset from the center axis of the hole in which you installed the retainer axis, the bolt and spring-loaded clamp, and a bolt provided with rollers, which are rigidly mounted thereon for engagement with the secret block, and the secret unit is made of longitudinal grooves and a radial groove for engagement with the spring loaded retainer.

Distinctive features of the present invention is that the casing is provided with a locking axis and a spring-loaded detent in the casing and radial offset from the center axis of the hole in which you installed the retainer axis, the bolt and spring-loaded clamp, and a bolt provided with rollers, which are rigidly mounted thereon for engagement with the secret block, and the secret unit is made of longitudinal grooves and a radial groove for engagement with the spring loaded retainer.
