Abstract

The driven coupling rod with locking mechanism is for use in opening ventilators in greenhouses etc. After driving the rod a locking mechanism (5) acting at the opposite end, comes into operation until the moment when the drive (4) is switched on again. The rod can be arranged to withstand only a small pressure load, and when this becomes too great a small elastic kink is formed, causing rod length to be reduced. This results in a tension load from the locking mechanism on the rod, so that it does not permanently distort.
