In a drive rod lock the drive rod is moved from a lock cylinder through a step-down gearing between an open position and a closed position and vice versa. A coupling of the step-down gearing to the drive rod is proposed which permits, in the case of rotation of the lock cylinder through 2°×360°, of shifting the drive rod from the open position into the closed position against displacement, without a torque being introduced due to the blocking forces into the step-down gearing and thus the lock cylinder.

Drive rod lock comprising a drive rod (16) displaceable between an open position (FIGS. 1 and 1a) and a closure position (FIG. 2) in combination with at least one lock element (18, 78, 106, 114, 116), a lock cylinder (1), a step-down gearing (A) between the lock cylinder (1) and the drive rode (16)

Drive rod lock comprising a drive rod (16) displaceable between an open position (FIGS. 1 and 1a) and a closure position (FIG. 2) in combination with at least one lock element (18, 78, 106, 114, 116), a lock cylinder (1), a step-down gearing (A) between the lock cylinder (1) and the drive rode (16) for the displacement of the drive rod (16) between the open position and the closure position and a blocking device (28, 30) for the drive rod (16) which blocks the drive rode (16) in the closure position (FIG. 2) against displacement in the direction of the open position (FIGS. 1 and 1a) without torque introduction into the step-down gearing (A), where a control dog construction group (22) is fitted on the gear output drive rod drive pinion (20) for drive engagement with a dog engagement profiling (26, 26′) of the drive rode (16) and where further a stop dog (28) is fitted on the gear output drive rode drive pinion (20) for action upon a counter-abutment face (31) of the drive rod (16), characterized in that (a) the dog engagement profiling (26, 26′) is made with two recesses (26, 26′),
