Abstract

A lock catch for doors having holding elements thereon includes a catch housing formed with at least one door-mounted holding element-receiving slot therein. At least one locking lever is pivotably mounted within the catch housing. A spring is positioned within the catch housing to normally bias the locking lever to project into the slot. A first bevelled surface is formed on the locking lever and is engageable by the holding element on the door when the door is closed, such engagement resulting in pivotal movement of the locking lever in a first direction to permit entrance of the holding element into an inner end region of the slot inwardly of the locking lever. A second bevelled surface is formed on the locking lever is engageable by the holding element of the door upon withdrawal of such element from the inner end region of the slot in which it has been locked releasably. Such engagement effects pivotal movement of the locking lever in a second and different direction to permit withdrawal of the holding element from the slot. The spring is so positioned relative to the pivot axis of the locking lever and the bevelled surfaces thereof that the effective lever arm of the locking lever when the first bevelled surface is engaged by the holding element entering the slot is greater than the effective lever arm of the spring acting on the locking lever. Further, the effective lever arm of the spring acting on the locking lever is greater than the effective lever arm of the locking lever when the second bevelled surface is engaged by the holding element during withdrawal of the holding element from the inner end region of the slot.
