Abstract
The invention relates to a fitting with a handle for operating the lock follower of a lock fitted in a door or the like. The fitting comprises a fixing device for its fixing to the door or the like and for rotary mounting of the handle, which device is passed through by an operating rod mounted without play in the follower and inserted into a receiving opening of the handle. The receiving opening is so formed that it--going from a datum position--transfers directly to the operating rod rotary movements of the handle taking place in a first direction of rotation but is without influence on the operating rod with rotary movements of the handle taking place in the opposite direction of rotation, commencing from the datum position, at least within a predetermined range of rotation. The fixing device comprises a transmission mechanism which converts rotary movements of the handle, taking place in the opposite direction of rotation, commencing from the datum position, into rotary movement of the operating rod likewise taking place in the first-mentioned direction of rotation. Accordingly it is possible to turn the follower in the sense of rotation necessary for opening the lock both through right turning and through left turning of the handle.
