Abstract
Abstract This invention discloses door furniture such as door handles and the like for actuating a spindle operated door lock. The furniture includes a first component (2) which in use is fixedly mounted relative to the face of a door and a second component (4) which is movable relative to the first component, and a coupler (10) for coupling the second component to the spindle of the lock. The first component is located within the second component. Normally the second component includes a handle.
