Abstract
The invention comprises the essential operating mechanism for a vertical latching assembly for a closure. It provides adjustment screws, accessibly disposed, externally of the closure (door), for adjusting the effective lengths of the elongate, latch bolt-actuating elements. A centercase, which is mounted externally of the door, has attachment blocks slidably coupled thereto. The blocks carry limbs, of the top and bottom bolt-actuating elements, or rod connectors, and the adjustment screws are threadedly engaged with the limbs for moving them, selectively and adjustably, axially of the centercase.
Claims14
An operating mechanism for a closure latching assembly, comprising:
- a support plate, having a longitudinal axis, for mounting thereof onto an external surface of a closure, such as a door, gate, bulkhead, or the like;
- wherein
- said plate also has an inner, closure-interfacing and closure-engaging surface, and an outer, opposite, support surface;
- an elongate, latch bolt-actuating element;
- an
- attachment block;
- means coupling said block, slidably, to one of said surfaces to accommodate movement of said block axially of said plate;
- and
- means attaching said element removably to said block, in a given disposition relative to said block, for movement of said element in common with said block;
- wherein
- said attaching means includes adjusting means, accessibly disposed on said outer, support surface, selectively movable, relative to said block, for effecting relative movement, between said element and said block, for adjustably positioning said element, relative to said block, in selected dispositions other than said given disposition;
- and
- said adjusting means, said block, and said element have means mutually cooperative for causing relative movement between said element and said block coincident with movement of said adjusting means relative to said block;
- said block has a cavity formed therein;
- said element has a limb disposed in said cavity;
- and said adjusting means comprises an adjustment screw engaged with said block which (a) protrudes into said cavity, and (b) engages said limb.
