<p>A concealed mounting arrangement for attaching a handle to a rotatable stem without the need for using an exposed attachment screw is disclosed. In one embodiment, there is an adapter element fixedly mountable on the stem, and a handle element mountable on the adapter with a fit that allows relative rotational and axial movement therebetween. One of these elements is provided with a connecting pin that extends towards the other element and has an enlarged head near its outer end. The other of these elements is provided with a mounting slot comprising an access opening that faces said one element and receives the head therethrough when the elements are moved axially toward one another, an intermediate portion leading from the access opening in a direction of relative rotation between the elements and the intermediate portion has a shoulder engageable with the underside of the head during such rotation to prevent the elements from moving axially apart. An outwardly facing pocket portion is formed adjacentthefarend of the intermediate portion. It can receive the head when the head is aligned therewith after the elements have been moved axially apart. The engagement of the head and the pocket then serve to prevent relative rotation of the elements. A spring acts to hold the head in the pocket.</p> |
