The invention relates to a door lock having an oblique bolt. In the invention, stress of the parts of the oblique bolt susceptible to wear is reduced, wherein they remain functional longer. The oblique bolt consists of slanted surfaces on both sides such that the tip part is narrower at its tip than in the back part of the tip part. The tip part has recesses in its lower part and upper part, which extend from the tip to the back part. Both recesses are open at the end of the tip of the tip part and on the other slanted surface such that the recess of the upper part is open on the opposite slanted surface than the recess of the lower part. Both recesses have a turning piece.

Door lock

The invention relates to a door lock provided with an oblique bolt. The objective is to decrease the external force directed into to deadlocking organs. The oblique bolt consists of slanted surfaces on both sides such that the tip part is narrower at its tip than in the back part of the tip part. The tip part has recesses in its lower part and upper part, which extend from the tip to the back part. Both recesses have a turning piece. Additionally, the oblique bolt has a support piece and flexing organs. The turning pieces guide external force up to a given turning angle via the support piece and flexing organs into the deadlocking organs.

The deadbolting means of the lock according to the invention comprise a locking piece () to establish and release the locking of the deadbolting means in the deadbolting position. The locking piece is pivotably supported on the lock body () and comprises a mechanical control part () and at least one electrical control part (A,B). The mechanical control part is functionally linked to a mechanical controller. The electrical control part is functionally linked to an electric actuator.

A door lock with a bolt, wherein the bolt pieces of the dual-action bolt are prevented from turning away from each other as the bolt pieces have two projections () arranged to cooperate with the inner surface () of the front plate. In relation to the support of the bolt piece on the shaft (), one of the projections () is arranged on the opposite side in the axial direction compared to the other away-facing projection.

This invention relates to a door lock comprising a lock body () fitted with a front plate and a bolt (). The transfer of external force to the locking piece () in the lock body is reduced. The reduction of external force is arranged in two stages of transmission. At the first stage of transmission, the transmitted force is reduced using a wedge part () that is in force transmission contact with a lever (). The second stage of transmission constitutes the lever.

The present invention relates to a locking arrangement by means of which two parts can be locked to each other, such as locking a door to its frame construction. The locking arrangement comprises a first locking element fastened to the lock unit, a second locking element fastened to the counter part and an acting element being preferably a part of the lock unit. The first and second locking elements are gripping brackets, forming a hooked grip with each other when the lock unit and the counter part are against each other, when, for example, the door is locked in its opening. The gripping brackets are essentially in the direction of the movement of the door. The task of the acting element is to keep the gripping brackets in an overlapping position when the locking arrangement is locked. The position of the acting can be changed, and the current state of the locking arrangement depends on the position.
