  • Patent number: 5492378
    Abstract: A door lock has a forked latch 3 mounted capable of pivoting about a lock housing 1. It has a truncated conical oval recess 12 into which a component 11 with an also truncated conical oval region engages. A spring 14 presses the forked latch 3 against this component 11. As a result the friction between the forked latch 3 and the component 11 increases when the oval shape of the recess 12 and the component are offset 90.degree. from one another but not when the oval shapes are aligned in the same direction.
