Application No. 10/079,706
The operating unit 16 comprises a generally cylindrical casing coaxially received
within the bore 14 and which has inner and outer tubular knob spindle sleeves
respectively indicated at 28 and 30 mounted in fixed position thereon. The inner and
outer sleeves are generally cylindrical and project axially outwardly from opposite sides
of the casing 26 and beyond associated inner and outer faces of the door 12 to provide
journal support for inner and outer knob spindles to which the inner and outer knobs 19
and 20 are respectively attached. The operating unit 16 further includes inner and
outer rose liners 32 and 34, respectively received on the inner and outer sleeves 28 and
30, which provide closures for the inner and outer ends of the bore 14. A pair of roses,
respectively indicated at 36 and 38, cover the rose liners 32 and 34 and comprise the
finished trim for the lock assembly 10. The roses and rose liners are retained in
engagement with the opposite faces of the door 12 by adjustable inner and outer
thimbles 40 and 42 which respectively threadably engage the inner and outer sleeves
28 and 30. Each rose liner has retaining means which engage an associated face of
the door to hold the rose liner in fixed position relative to the door as will be hereinafter
further discussed. In addition, a means is provided to prevent rotation of the outer
spindle sleeve and the outer thimble relative to the outer rose liner whereby the
operating unit 16 is retained in fixed position within the bore 14. A means is also
provided to connect the outer rose to the outer rose liner to maintain the outer rose in
fixed relation to the door.
