The disadvantage of this lock is that its design does not allow to expand the consumer capabilities of the castle in terms of the use of additional electronic control.

The technical result consists in the implementation of such an additional function of the lock as the possibility of electronic control, and it’s enough to use standard handles with the ability to lift the handles up to the lock.

The technical result is achieved by the fact that the lock contains a key secrecy mechanism installed in the housing, interacting with the zugalt and the deadbolt, a spring-loaded handle lever, one end interacting with the latch, the deadbolt mounted to rotate and contact the deadbolt, the handle lever is equipped with a deadbolt cam and has the ability to rotate both clockwise and counterclockwise on an axis fixed in the housing. There is a pluggable lever located rotatably around the axis of the handle, having the ability to interact with one of its shoulders with the bolt lever, the second shoulder with a return spring, the ratchet axis is located on the third shoulder, on which the ratchet is mounted rotatably, and the fourth shoulder interacts with one face from the shoulders of a movable lever mounted on the bolt axis with a zugalt lever that interacts with the other arm of the zugalt, while the ratchet is equipped with a hook interacting with the handle lever azom ratchet accommodating the pusher, the pusher is fixed at its one end to the housing and its other end engages with worm coaxially fixed to the motor shaft supported on the lock body.

A rocker is installed in the housing parallel to the movement of the bolt, with one shoulder having the ability to interact with the lever of the handle, and with the other shoulder being able to interact with the zugalt spacer mounted on the bolt or on the housing with the ability to move and engage with the zugalt to raise it.

The return spring is mounted on the shaft of the lever of the handle and preloaded in such a way that one and the other ends abut against the spring stop installed in the housing from opposite sides, and between the ends of the spring there is the other end of the handle lever and the second arm of the connected lever.

The invention is illustrated by drawings, which depict:

FIG. 8 - handle lever (detail 14).

The lock comprises a housing 1 with a guide axis 2 of the bolt, a housing cover 3 and a strap 4.

A bolt 5 is installed in the lock case 1 with a bolt plate 6. A longitudinal groove 7 is made on the bolt plate 6 and open grooves 8 are placed along its longitudinal edge 8. In the longitudinal groove 7 there is a bolt axis 2. In the open grooves 8, it is possible to accommodate the hook 9 of the zugalt 10. In the case there is also a spring-loaded latch 11 with a shank 12 and a stop 13 installed on the end of the shank, the lever of the handle 14, made in one piece with the shaft 15 of the lever and mounted on the axis of the handle 16.

The lever of the bolt 17 is mounted on the axis of the lever of the bolt 18 and interacts with one end 19 of the cam 20 of the handle lever, and its other end, through the groove of the lever of the bolt 21, interacts with the protrusion 22 of the bolt plate 6.

In the lock housing 1, on the axis of the handle 16, a hooked lever 23 is mounted that can be rotated around the axis of the handle 16 and interacts with one shoulder 24 and a shoulder 25 of the bolt lever 17, interacting with a return spring 27 with the second shoulder 26, the ratchet axis 28 is located on the third shoulder , on which the ratchet 29 is mounted with a possibility of rotation, and the fourth shoulder interacts with the face of the zugalt 31 with its face 30.

The lever of the zugalt 31 is movably fixed on the axis 2 of the bolt and with one shoulder 32 interacts with the connected lever 23, and the other with its shoulder 33 interacts with the protrusion of the zugalt 34.

The ratchet 29 is provided with a ratchet hook 35, which cooperates with the handle 36 of the handle 14 and is equipped with a ratchet groove 37, in which the pusher 38 is located. The pusher 38 is fixed with its one end 39 to the housing 1, and the other end 40 interacts with the worm 41 coaxially fixed on the shaft of the electric motor 42.

An electric motor 42 is installed in the lock housing. The stop 43 of the return spring 27 is also installed in the housing. The return spring 27 is preloaded and axially mounted on the shaft 15 so that one end of the spring 45 and the other end of the spring 46 abut against the stop 43 from opposite sides. Between the end of the spring 45 and the end of the spring 46 is the shoulder 44 of the lever of the handle 14 and the shoulder 26 of the connected lever 23.

Castle work

The lock can be closed and opened in two options.

First option

Closing and opening

Opening and closing the lock occurs using the cylinder mechanism of the lock. When you turn the key or handle of the cylinder mechanism, the cam of the handle lever 20 raises the spring-loaded zugalt 10, unlocks the bolt plate 6 and moves the bolt in the direction of opening or closing the lock.

Opening the latch always occurs when you press the file handle. In this case, the lever of the handle 14 interacts with the stop 13 of the shank 12 and the latch 11 is inserted into the cavity of the lock case.

Second option

Closing

The lock can always be closed by lifting the handle up.

In this case, the lever of the handle 14 with one shoulder 47 interacts with the shoulder 48 of the rocker arm 49. In this case, the other shoulder 50 of the rocker arm, interacting with the face 51 of the spacer 52, raises it and it, with its opposite face 53, interacting with the hook 9, raises the zugalt 10 bringing the hook 9 out of contact with the open grooves 8 of the bolt plate 6.

In turn, the lever of the handle 14 with the cam 20 interacts with the end 19 of the lever of the deadbolt 17, rotates it, which with its other end through the groove 21 interacts with the protrusion 22 of the plate of the deadbolt 6 and pushes the deadbolt 5 from the cavity of the lock body.

The castle is closing.

Opening

The lock can always be opened after applying voltage to the electric motor 42 with a certain polarity from the control electronic part of the lock.

When voltage is applied to the electric motor 42, the worm 41 starts to rotate and moves the end 40 of the pusher 38 from the lower position to the upper position.

In this case, the middle part of the pusher 38, which is located in the groove 37, rotates the ratchet 29 and engages the hook 35 of the ratchet 29 with the reverse gear 36 of the handle lever 14.

Further, when you press the file handle through the shaft of the lever 15, the lever of the handle 14 is rotated, the latch opens and the lever of the connected 23 rotates, which interacts with the face 30 with one shoulder 32 of the lever 31, and interacts with the shoulder 33 with the other shoulder 33 and raises a zugalt 10.

After raising the zugalt 10 and further turning the lever of the handle 14, it interacts with the shoulder 24 of the connected lever 23 and at the end 19 of the bolt lever 17. The lever of the bolt 17 rotates around the axis 18 and its other end, acting through the groove 21 on the protrusion 22 of the bolt plate 6, pushes the bolt 5 out of the cavity of the castle.

When you release the rotary handle, the handle takes a horizontal position due to the action of the return spring 27.

The return spring 27 returns to its initial position the lever of the handle 14, acting on the shoulder 44 located between the end 45 and the end 46 of the return spring 27.

The return spring 27 also returns to the initial position and the connected lever 23, acting on the shoulder 26, also located between the end 45 and the end 46 of the return spring 27.
