Abstract
A locking mechanism comprises a housing, a shaft extending in the housing and having a latch member thereon adjacent to one end thereof, and an actuating lever adjacent to an opposite end of a shaft. The shaft, actuating lever, and housing are interconnected in a manner that causes the shaft to move longitudinally in response to turning of the actuating lever to a predetermined extent from a rest position, so that the latch member moves from a first position to a second position, and for causing the shaft to tilt in response to continued turning of the actuating lever, so that the latch member is turned away from the second position.
Claims8
A locking mechanism comprising a housing, a shaft extending in said housing and having a latch member thereon adjacent to one end portion thereof, an actuating lever adjacent to an opposite end portion of said shaft, said shaft and said actuating lever being interconnected for conjoint translational movement of said shaft and said actuating lever and for pivotal movement of said actuating lever relative to said shaft, and a guiding system that guides movement of said shaft and said actuating lever in said housing for causing conjoint translational movement of said shaft and said actuating lever in said housing in response to a predetermined degree of turning of said actuating lever from a rest position relative to said shaft, whereby said latch member moves from a first position to a second position, and for causing said shaft to tilt relative to said housing in response to further turning of said actuating lever, whereby said latch member is turned away from said second position;
- wherein the interconnection of said actuating lever and said shaft includes a pivot member pivotally connecting said opposite end portion of said shaft to said actuating lever at a point between opposite ends of said actuating lever, and wherein said guiding system guides said pivot member for reciprocation in said housing, guides one end of said actuating lever, adjacent to said shaft, for arcuate movement in said housing transverse to said shaft, and guides said shaft for movement longitudinally of said shaft when said operating lever is turned to said predetermined degree and for movement laterally of said shaft during said further turning of said actuator lever, and wherein said actuating lever has a manually engageable portion for turning said actuator lever.
A locking mechanism comprising a pivoting actuating lever and a curve-controlled tension hook that pivots and at the same time is shifted longitudinally, characterized by the fact that a pivot point of said actuating lever is also a coupling point of the tension hook and the actuating lever and may be displaced in the direction of the longitudinal shift, that an arm of the actuating lever that extends beyond the pivot point has a gudgeon that runs in a control curve responsible for the longitudinal shift, between opening and tension positions, and moves beyond a dead center line which runs through the pivot point of the actuating lever and a claw of the tension hook, and that an end of the tension hook that is opposite to the claw of the tension hook is designed as a filling piece which penetrates an aperture of the actuating lever until it is flush with its surface.
