Abstract
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.
