Description of the invention

The subject of the invention is a multi-point mortise lock used in construction.

Known multi-point locks consist of: a main lock having a drive transmission system with a locking assembly and a latch system, an auxiliary lock having an independent locking system, cooperating locks having a locking system controlled by the main lock, and control strips slidably fastened to the faceplate.

The drive transmission systems used so far allowed the use of a locking system in the form of a bolt, which has a specific mechanical strength, often too small in relation to the requirements, but did not allow the simultaneous use of more locking elements with larger dimensions and greater mechanical strength.

According to the invention, the main lock has a slider driver rotatably mounted on a pin, in the shape of a circular segment, having a circular end protruding from one side, cooperating with a recess made in the bolt body, and on the perimeter a toothing meshing with the slider toothing. An intermediate control strip is placed between the main lock and the auxiliary lock. The auxiliary lock additionally has a slider cooperating with the intermediate control strip and the upper control strip. The main lock and the auxiliary lock each have at least two locking elements. Preferably, the thickness dimension A of the locking elements is at least 60% of the thickness dimension B of the overall lock. Further advantages are obtained if the locking portion of the locking element is in the shape of a pin.

In the lock according to the invention, the design of the power transmission mechanism allows the use of several locking elements with high mechanical strength. The use of an intermediate control bar and an additional slider in the auxiliary lock allows for the operation of the auxiliary lock independent of the main lock.

The subject matter of the invention is illustrated in the embodiment in the drawing, in which fig. 1 shows the main lock in a partially exposed view, fig. 2 - auxiliary lock in a view with a partially exposed cover, and fig. 3 multipoint lock with locks: main, auxiliary and cooperating.

The main lock 1 has a driver of a slider 3 rotatingly mounted on a pin 2, in the shape of a circular segment, having a circular end 4 protruding from one side, cooperating with a recess 5 made in the bolt body 6 and, on the perimeter, toothing 7 meshing with the teeth 8 of the slider 9. Between the main lock 1 and the auxiliary lock 10 there is an intermediate control strip 11. The auxiliary lock 10 additionally has a slider 12 cooperating with an intermediate control strip 11 and an upper control strip 13. The main lock 1 has four locking elements 14 and the auxiliary lock 10 has three locking elements 14. Locking parts the locking elements 14 in this embodiment have the shape of a pin.

The principle of operation of the lock is as follows. The rotational movement of the driver of the cylinder insert 15 of the main lock 1 causes the movement of the body of the bolt 6 and the rotation of the driver of the slider 3, which, with the help of toothing 7, transfers the drive to the toothing 8, causing the slider to move 9. The slider 9 causes the control strips: the intermediate 11 and the lower 16 to move. The intermediate control strip 11, by means of the slider 12 of the auxiliary lock 10, causes the upper control strip to move 13. The sliding of the control strips causes the locking elements 14 to slide out of the boxes of the main lock 1 and interlocking elements 17 of the cooperating locks 18. Rotation of the cylinder insert 19. the auxiliary lock 10 causes the locking elements 11 to extend and close. The auxiliary lock 10 works independently of the others. The entire multipoint lock is in the closed state. Opening the lock is similar to the opposite.
