The invention relates to a lever arm device 16, 17 for connection 6, 8 to control mechanisms 5 linked to swing doors 3 and the like. The invention solves, inter alia, the problem of reducing necessary mechanism space between the wall (Fig. 2) towards which the door 3 is swung open, in the open position, and the door leaf itself. The fundamental element of the invention lies in the arrangement of a bell crank 16, 17, which, in the open position of the door leaf, assumes a direction running parallel with the door leaf, alongside this very door leaf. <IMAGE> |
