A handle arrangement 10 for operating a retaining mechanism of a bi-fold door having a handle 12 movable between retained and released positions for respectively engaging and releasing the retaining mechanism, a locking mechanism 16 for locking the handle 12 in the retained position, including a keyway 14 disposed behind an aperture 17 in the handle for allowing a key to be inserted into the keyway 14, through the aperture, when the handle is in the retained position, but preventing movement of the handle 12 out of the retained position whilst the key is inserted. As such the handle can only be operated when no key is inserted preventing a protruding key bow damaging adjacent door panels when folded. An end of the handle 12b may pivot away from the door panel, and then rotate about an axis 26, perpendicular to the panel, between retained and released position. The handle is preferably received in a recessed back plate 18. |
