Abstract

A lockset for use in a door assembly is provided and includes an interior mechanism having a first escutcheon, a first housing, and a first retainer shield and an exterior mechanism having a second escutcheon, a second housing, and a second retainer shield. In addition, a spindle assembly is provided to interface with a latch mounted on the door assembly and allow for selective locking of the lockset. The spindle assembly is lockable in one of two rotational positions relative the first and second escutcheons when the first housing engages the first retainer shield and the second housing engages the second retainer shield. By providing rotational adjustment of the spindle assembly relative the first and second escutcheons, the lockset is able accommodate either a left or a right-handed door.

Claims (14)

1. A method of installing a lockset on a handed door, the method comprising the steps of:

applying a force to a bearing mounted on an external mechanism of the lockset against a biasing force of a first biasing member;

rotating said bearing into engagement with a first housing fixedly supported by a spindle assembly of the lockset;

rotating said bearing and said first housing until said spindle assembly is properly aligned with a latch of the handed door;

releasing said force on said bearing to allow said first biasing member to bias said first housing into engagement with a first retainer shield to lock said spindle assembly and said first housing relative a first escutcheon;

applying a force to a second housing mounted on an interior mechanism of the lockset against a biasing force of a second biasing member;

rotating said second housing to rotatably position said interior mechanism relative said exterior mechanism and the handed door; and

releasing said force on said second housing to allow said second biasing member to bias said second housing into engagement with a second retainer shield to lock said second housing relative a second escutcheon.

2. The method of installing a lockset on a handed door of claim 1 wherein said first housing includes a first pair of posts, said first posts operable to selectively engage a first pair of slots formed in said first retainer shield to selectively lock said first housing relative said first retainer shield.

3. The method of installing a lockset on a handed door of claim 2 , wherein said first set of posts are diametrically opposed and said first pair of slots are diametrically opposed to provide said spindle assembly with 180° of rotational adjustment relative said first escutcheon.

4. The method of installing a lockset on a handed door of claim 1 , wherein said second housing includes a second pair of posts, said second pair of posts operable to selectively engage a second pair of slots formed in said second retainer shield to selectively lock said second housing relative said second retainer shield.

5. The method of installing a lockset on a handed door of claim 4 , wherein said second set of posts are diametrically opposed and said second pair of slots are diametrically opposed to provide said spindle assembly with 180° of rotational adjustment relative said second escutcheon.

6. The method of installing a lockset on a handed door of claim 1 , wherein said first biasing member is a spring.

7. The method of installing lockset on a handed door of claim 1 , wherein said second biasing member is a spring.
