Drive with a lever gear for an espagnolette

摘要

Lever axle gear has connection between operating lever (20) and guard rail (17) which is decoupled at stationery fulcrum (21) or between operating lever and connecting lever (40) at first bearing (41) or between the connecting lever and connecting rod (16) at second bearing. The operating lever does not stay in drive connection with the connecting rod. The connection between the operating lever and the guard rail is made by actuating the operating lever at the stationery fulcrum or between the operating lever and the connecting lever at the first bearing or between the connecting lever and the connecting rod at the second bearing, so that the operating lever stays in drive connection with the connecting rod.
