US 2006/0055183 A1 · Push button lock mechanism for a handle set

Abstract

A handle set includes a handle assembly having an operator, a rose insert, and a shank having a bore. The rose insert has a central opening and a post. The shank is affixed to the operator and rotatably received in the central opening. A rotational stop is coupled to the rose insert. A spindle guide is slidably received in the bore and is slidable between a locked position and an unlocked position. A kick-off plate having a retention slot is coupled to the spindle guide. A centralizing cup having a single multi-function tang and a lock retention feature is mounted to the shank. The multi-function tang is configured for rotation along a rotational path, the rotation being limited by the rotational stop. The lock retention feature is positioned to engage the retention slot when the spindle guide is in the locked position to thereby retain it in the locked position.

Dependent claims

A handle set, comprising:

a handle assembly including an operator, a rose insert, and a shank having a bore, said rose insert having a central opening and a post, said shank affixed to said operator and rotatably received in said central opening;
a rotational stop coupled to said rose insert;
a spindle guide slidably received in said bore, said spindle guide being slidable between a locked position and an unlocked position;
a kick-off plate having a retention slot, said kick-off plate coupled to said spindle guide;
and
a centralizing cup mounted to said shank, said centralizing cup having a single multi-function tang and a lock retention feature, said multi-function tang configured for rotation along a rotational path, said rotation of said multi-function tang along said rotational path being limited by said rotational stop, and said lock retention feature being positioned to engage said retention slot of said kick-off plate when said spindle guide is in said locked position to thereby retain said spindle guide in said locked position.

3 more elements

A method of operating a push button lock mechanism in a handle set, comprising:

pushing a lock button to cause a spindle guide having a kick-off plate coupled thereto to slide into a locked position to lock said handle set, said kick off plate having a retention slot in engagement with a lock retention feature of a centralizer cup to thereby retain said spindle guide in said locked position;
and
turning an operator to cause said kickoff plate to kick off of a locking cup to drive said spindle guide into an unlocked position thereby overcoming said lock retention feature engagement with said retention slot and unlocking said handle set, wherein a rotational stop is engaged by a multi-function tang of said centralizer cup to limit a rotation of said operator.
