ABSTRACT:
A rod lock for doors or gates having two wings, comprising a locking rod or bar mounted at one wing for vertical displacement. The locking rod, in its closed position, engages into a recess or depression in a floor or the like. The other wing has at least one stop or impact member against which bears the wing having the locking rod. A door lock is effective between both of the wings. At least two guide rings are provided in which the locking rod is vertically displaceable and rotatable about its lengthwise axis. A locking or closure element mounted at the rod is pivotable together with the rod and intended to engage in its closed position between the mutually contacting door wings. A retarding or inhibiting element at the counter-wing prevents lifting of the locking element and thus the locking rod or bar.
