Rotating catch lock, specially for motor vehicles

Abstract

The invention relates to a rotating catch lock, wherein a closing member ( ) interacts with a catch ( ), which can be rotated between a closing position accommodating the closing member ( ) and an open position which releases said member. The catch ( ) is force-loaded ( ) in an open position and is held by a spring-loaded ( ) rotating latch ( ) in the close position. Said latch ( ) is moved by a motor ( ) between the locking position retaining the catch ( ) and a stand-by release position in which the spring-loaded latch ( ) is propped up by the catch ( ) as long as it remains in an open position. In order to use small compact motors ( ), the invention provides that the stored energy ( ) exerted by an energy storage mechanism ( ) is transmitted to the latch ( ) via a storage lever ( ). Normally, the latch ( ) is shifted into its stand-by position by the storage lever ( ). When the latch ( ) is in a stand-by position, the storage lever ( ) is supported on a control tappet ( ) which is rotationally driven by the motor ( ). The motor ( ) can be driven by an electrical control logic in both a forward mode ( ) unloading the energy storage ( ) and a reverse mode (56′) loading the energy storage ( ), i.e. in opposite directions. In the reverse mode (56′) the control tappet ( ) releases the latch ( ), moves towards the storage lever ( ) and guides it back into a starting position which corresponds to the stand-by position of the latch ( ).
