Fitting arrangement for a door handle

An arrangement for fitting a handle device in an openable and closable element of a predetermined thickness, such as a door or a window, there being disposed, interiorly in the element a lock chamber through which extends a rod with a handle at each side of the element, and there being disposed between each handle and the element a washer or cover plate through which the rod also extends, and the rod being, in response to the predetermined thickness, insertable a greater or lesser distance in an opening in at least one of the handles and fixable there by means of an adjustable coupling, wherein the rod comprises a series of transverse grooves on an outwardly-facing surface of the rod, and the rod is provided with a slot through the outside of the rod, wherein the adjustable coupling comprises

• a body adapted to be fixed to the at least one handle, the body having barbs adapted to engage with the grooves on both sides of the slot, wherein the washer or the cover plate is connected to an adjustment device for adaptation of a position of the washer or the cover plate to a predetermined thickness, the body having a first end, a second end, a first flange extending substantially perpendicularly from the first end and a second flange extending substantially perpendicularly from the second end in a direction opposite the first flange, the adjustment coupling being separate from the washer or the cover plate and being fixable by radially outwardly engaging with the handle and engaging radially inwardly with the rod, and that the adjustment device and the lock chamber are interconnectable to one another by an intermediary of a coupling.
