Description

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

A known lock according to the patent of the Russian Federation No. 2019659 (publ. 15.09.94), comprising a housing with a cover having axial holes, a deadbolt with a gear rack located therein, a bolt movement mechanism including a rotary disk with axial holes coaxial with the body holes, spring-loaded paired locking pins located in the holes of the housing and the disk, a locking means and a socket wrench for interacting with the locking pins.

The disadvantage of this design is the presence of springs in it, interacting with locking pins. This makes it possible to move the locking pins in both directions in order to select their unlocking position, and as a result of breaking the lock.

The closest in technical essence is the castle according to the patent of the Russian Federation No. 2123569 (publ. 20.12.98). This lock consists of a housing with a cover in which axial holes are made, a bolt in the form of a gear rack and a bolt movement mechanism including a handle shaft, gear, a rotary disk with axial holes coaxial with the cover holes, of paired locking pins placed in the holes the cover of both the disc and the socket wrench for interacting with locking pins. The lock is also equipped with a piston, freely mounted on the handle shaft and interacting with freely moving locking pins, while the handle shaft has a collar interacting with the piston, and the key is made with holes located coaxially with the axes of the locking pins. Between the end face of the shaft-handle when it is pulled out of the lock body and the lid, a gap is formed to accommodate the key.

The disadvantages of this design include the following:

a) The shaft-handle can be removed quite easily, and this will lead to free access to the secret part of the castle. With the remote shaft-handle in a known lock, it becomes possible to open it. To do this, after removing the handle shaft, all paired locking pins are displaced into the lock body to the stop, and then each of the stepped pins is extended from the lock body to the stop. In this position, the stepped pins are in the cover, and the rest of the pins in the disk, that is, the interface plane between the disk and the cover will not intersect any of the pins - this means unlocking the bolt mechanism of the lock. In practice, this is quite difficult to do due to sticking of the pins from grease, magnetization, and so on, but theoretically there is such a possibility. In addition, in such a lock, the locking pins are poorly protected, since when the shaft-handle is pulled out of the lock body, it becomes possible to break or bend at least one of the stepped locking pins protruding from the lid, acting on them through the key gap with foreign objects.

b) The lock has one deadbolt, which dramatically reduces the resistance of the door to force impact on it (for example: spinning, sawing hinges, etc.).

c) The mechanical key of the lock, made with holes for the pins, cannot be made with zero tolerance, and a high degree of accuracy of all parts of the lock is a high degree of security and reliable operation.

The present invention solves the problem of increasing the degree of protection of the lock from the rough effects of foreign objects, in particular, on the handle shaft when trying to remove it and, acting on the locking pins, open the lock without a key, as well as being protected from the effects of the external environment - dust, moisture.

To achieve this technical result, in a lock containing a housing, a cover and a rotary disk with holes in which freely moving locking pins, a bolt, a bolt moving mechanism including a handle shaft and a piston interacting with the locking pins, a socket wrench made with holes are installed located coaxially to the axes of the locking pins, a cylinder is rigidly mounted in the housing, in which, as in the rotary disk, coaxial holes are made for the locking pins, and on the cylinder with the possibility of axial rotation A lid is fitted, in the cylinder and in the lid, key-hole recesses and coaxial openings for the shaft-handle are made, while the case has bolts that are located in different planes parallel to the plane of their movement, in addition, the lock is additionally equipped with an internal handle the grooves are made: on the outside, according to the number of deadbolts, inside, one, they have rollers for interacting with the deadbolts and the rotary disk, in which grooves for the rollers are also made, and a sleeve with a step a collar interacting with the piston freely mounted on it and the internal handle, while the internal handle and the shaft-handle are pivotally connected by rods, in addition, a protective washer is freely installed on the shaft-handle, positioning the locking pins with respect to the socket wrench placed in the gap formed by the shaft end of the handle and the protective washer, and the locking pins are made of more than two detachable parts, one of these parts is made in the form of a stepped shaft, the other in the form of a pin freely moving into the cylinder guide, and in the holes of the socket wrench are fixed in the code position stops.

Distinctive features of the proposed lock is that a cylinder is rigidly mounted in the housing, in which, as in the rotary disk, coaxial holes are made for the locking pins, and a cover is mounted on the cylinder with the possibility of axial rotation, and key-hole recesses are made in the cylinder and the cover and coaxially the holes for the shaft-handle, while the bolts are installed in the housing, which are located in different planes parallel to the plane of their movement, in addition, the lock is additionally equipped with an internal handle in which the grooves are made: on the outside, according to the number of deadbolts, inside, one, they have rollers for interacting with the deadbolts and a rotary disk, in which grooves for the rollers are also made, moreover, a sleeve with a stepped collar is rigidly placed on the handle shaft, interacting with a piston freely mounted on it and the internal handle, while the internal handle and the shaft handle are pivotally connected by rods, in addition, a protective washer is freely mounted on the shaft shaft, which positions the locking pins with respect to the socket wrench located in the gap, the shaft of the handle shaft and a protective washer, and the locking pins are made of more than two detachable parts, one of these parts is made in the form of a stepped shaft, the other in the form of a pin that moves freely in a cylindrical guide, and fixed in code position stops.

Due to the presence of these signs, the lock is most fully protected from the effects of the external environment, shock, as well as the impact of foreign objects on the locking pins when trying to open the lock without a key. Blocking of the socket key is excluded, since now its code is adjusted by moving the stops in the code position according to the code arrangement of the lock pins, which eliminates the influence of manufacturing errors of the lock parts.

The rods create axial force along the shaft of the handle, which occurs under the action of gravity and maximally in the position when the shaft of the handle is pulled out of the cylinder until it stops. This eliminates the possibility of acting on the pins with vibration in order to move them to the right or left to unlock the lock, the handle shaft will always be pushed into the lock body.

The cover does not allow the shaft handle to extend a greater distance than the thickness of the key, which is placed in the recess of the cover and cylinder. It is practically impossible to tear it out. The lid perceives all gross influences, even significant efforts on the shaft-handle will not disable the lock. The stepped collar of the sleeve, interacting with the internal handle, provides a more rigid position of the shaft-handle. The backlash in the radial direction of the handle shaft is reduced.

The fact that the locking pins are made of more than two detachable parts, increases the ability of the lock to withstand the effect of the selection of the unlocking position of the pins to external influences, namely the work of the master key. If the handle shaft is removed, which is extremely difficult, the action of the master key will cause the pin moving in the cylindrical guide to be radially shifted as soon as it crosses the plane of the cylinder connector and the rotary disk. The resulting protrusion will lead to the fact that the pin with further advancement with its master key rests against the plane of the disk connector, creating the effect of stop. The middle pin is so long that in extreme positions it is either in the cylinder or in the rotary disk and cylinder. Its length can have the following values: if Xmax is taken as the maximum movement of the locking pins, and L is the length of the middle pin, then the following inequality L-Xmax> 0 should be fulfilled.

The following is an embodiment of the invention that does not exclude other variations within the scope of the claims.

The proposed castle is illustrated by the drawings shown in figures 1-6.

The lock comprises a housing 1 with a cover 2 and a rotary disk 3 with holes in which freely moving locking pins 4 are installed. In the housing 1, a cylinder 5 is rigidly installed, in which, as in the rotary disk 3, coaxial holes are made for the locking pins 4, and on the cylinder 5, a cover 2 is mounted rotatably, fixed from axial displacement by the retaining ring 6. Four bolts 7 are installed in the housing 1, which are located in different planes parallel to the plane of their movement. The bolt movement mechanism includes a handle shaft 8 and a piston 9 interacting with locking pins 4. In the cylinder 5 and the cover 2, recesses for the socket key 10 and coaxial holes for the handle shaft 7 are made coaxially. The lock is provided with an internal handle 11 in which the grooves are made : outside four, respectively, the number of bolts 7, inside - one. The rollers are installed in these grooves, the outer rollers 12 for interacting with the bolts 7, the inner roller 13 - with a rotary disk 3. In the bolts 7 and the rotary disk 3 is also made in the groove under the rollers 12, 13. A sleeve 14 is rigidly mounted on the handle shaft 8 with a stepped collar interacting with the piston 9 freely mounted on it and the internal handle 11. The internal handle 11 and the shaft handle 8 are pivotally connected by rods 15. In addition, a protective washer 16 is freely mounted on the shaft handle 8, which positions the locking pins 4 in relation to the socket wrench 10. Locking e pins 4 are made of three detachable parts, one of these parts is made in the form of a stepped shaft 17, the second in the form of a pin 18, the third in the form of a pin 19, freely moving in a cylindrical guide 20.

The socket key 10 is placed in the gap formed by the end face of the shaft-handle 8 and the protective washer 16, and in its holes coaxial to the axes of the locking pins 4 (17, 18, 19, 20), the stops 21 fixed in the code position are located.

The castle operates as follows. The shaft-handle 8 (figure 2), fixed by a pin 22 in the groove of the rotary disk 3, is withdrawn from the lock body until it stops along the groove made for the pin 22 together in the rotary disk 3 and cylinder 5. As a result of this movement, the protective a washer 16, which is affected by a sleeve with a stepped collar 14. In the gap formed between the protective washer 16 and the end face of the handle shaft 8, a socket key 10 is inserted through a recess made jointly in the cover 2 and the cylinder 5. The protective washer 16 interacting with the socket key 10 and locking pins 4, position ionizes the key relative to them, since a protrusion is made on the protective washer 16 (Fig. 5), the size corresponding to the groove of the key 10. The stops 21 of the key are thus mounted coaxially with the locking pins 4. After installing the socket key 10 in the gap, press the shaft handle 8, while the key is inserted into the body of the lock and moves with its stops 21 step pins 4 (17) and 4 (18) at certain distances into the interface plane of the rotary disk 3 and cylinder 5. Next, turn the shaft of the handle 8 to the right or left to locking or unlocking the lock due to air Twisted on the unlocked disk 3 with a pin 22 installed in the shaft-handle 8. The disk 3 (figure 4), turning, acts on the inner handle 11 with the roller 13. The inner handle 11 moves the bolts 7 to the right or left, acting on them with the rollers 12. After This shaft handle 8 returns to its original position and is pulled out of the lock. In this case, the protective washer 16 pushes the socket wrench 10, and it is removed from the gap formed between it and the end of the handle shaft 8, through a recess made in the cover 2. As a result of this movement, the piston 9 restores the locking pins 4. The shaft handle 8, upon termination of the impact on it by hand, it partially slides into the body of the lock under the action of the force that arises in the rods 15. When opening the lock, while indoors, turn the inner handle 11, which, through the rollers 12, moves the bolts 7.

When installing the lock, the recess of the cylinder 5 under the key is combined with the recess of the cover 2, and the latter is pressed against the door leaf. With a rough impact (trying to knock it down, etc.), it rotates around its axis and blocks access to the secret part of the castle.

The proposed castle stands out among similar ones, significantly increasing consumer qualities. The unusual appearance of the castle also attracts attention to it. The basic design of the lock can be changed, taking into account the needs of the potential buyer, the lock with two bolts can be used for the door, with four - for the safe, etc. Market research and the operation of prototypes have shown that the proposed castle can be used in a wide range: apartments, offices, safes, banks, rooms with limited access. The proposed lock also fits perfectly with any electronic systems, which makes it possible to use it for almost any protection purpose.
