Drive apparatus for a door leaf and a door arrangement equipped therewith
A drive apparatus 10 for a door closer, having a housing 12, a closing piston 14 which is displaceably arranged in the housing for coupling to a door leaf, and a spring arrangement 24 in the housing having a closing spring 26 providing a closing force on the closing piston, and an auxiliary spring 38 arranged in the same side of the housing as the closing spring, and which can be switched between an active (Fig 1a) and an inactive state (Fig 2b) via adjustment of a stop 30 54 60 for a compression element 46 acted on by the auxiliary spring. The stop may be continuously adjustable allowing the auxiliary spring to vary the force applied before having it removed altogether. The stop can be manually, electrically or electromagnetically adjusted. The closing spring and auxiliary spring may be co-axial and may overlap with each other. The compression element may move as a result of the stop within the closing spring. A tension element 48, e.g. a rod, chain, belt, cable may transfer the force from the stop to the auxiliary spring.
