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.

Field-reversible locking mechanism

A collar coacts with a chassis, sleeve and lever of a lockset to provide a retention and reinforcement system for lock assemblies. The collar has a flanged portion and a sleeve-engaging portion and is sandwiched between a lever and the cylinder. The sleeve-engaging portion includes at least one tab that engages the sleeve to retain the collar on the sleeve. Alternatively, the collar can be staked to the sleeve. A spring washer can be mounted between the collar and the chassis to take up variation in manufacturing tolerances. The result is a retention and reinforcement system that provides a protection against attack in the zone of attack around the handle-chassis interface.

Retention and reinforcement system for knobs and levers

A keyed knob assembly ( ) having a knob portion ( ), a knob insert ( ) partially received within a bore ( ) formed in the knob portion ( ) and a shank portion ( ) partially covering the knob insert ( ) is disclosed. A throughbore ( ) formed in the knob insert ( ) is provided which operably supports a locking cylinder assembly ( ). An axial channel ( ) formed in the shank portion ( ) terminates at a radial slot ( ) to provide a means for releasably coupling the knob,assembly ( ) of the present invention to a catch ( ) of a lever catch subassembly associate with the chassis of the lockset.

Cylinder portion of a lever-type lockset

An electronic module which is located between the plug cover and the front flange of the cylinder body has light and motion sensors that look out through holes in the cover. Whenever it is dark and a person approaches the lockset a light will be turned on to illuminate a translucent ring that surrounds the keyway.

Door lock cylinder face

An auxiliary lock comprises a latch assembly having an elongated casing to be received by a first horizontal bore extending into the end of the door. A cylinder mechanism is received by a second horizontal thru bore extending, from one face of the door to the other face of the door and intersecting the first bore. The cylinder mechanism includes a cylinder having a chimney, a cylindrical guard having an annular door engaging surface, an annular lip projecting inwardly from the annular door engaging surface to be received by the second thru bore, a cylindrical segment projecting inwardly from the annular lip, and a strut projecting radially upwardly from one circumferential end of the segment and defining therewith a shaped structure. The strut has a length selected so that the shaped structure lies proximate the bottom of the casing to thereby prevent the rotation of the said guard.

Auxiliary lock

A weatherproof casing for a padlock having a body and a shackle. A lower casing includes a body, a bottom cap having a flat bottom and an annular wall projecting therefrom, and a strap connecting the body and the bottom cap. The casing body includes an upper portion conforming to the shape of the padlock body and open at the top for receiving the body of the padlock, and an upper casing in the form of a cap having an annular downwardly projecting flange defining an opening for receiving the top of the lower casing body. The lower casing body additionally includes an enlarged flange at the bottom defining a second opening for receiving the annular wall of the bottom cap. The strap extends between the side of the bottom of the bottom cap and the side of the enlarged flange proximate the top thereof.

Weatherproof padlock

A deadbolt or auxiliary lock is disclosed which can be mounted in a small (11/2') or large (21/8') lock set hole. A reversible cast adapter is provided which has a plate portion, small and large diameter annular lips on one side and a small diameter lip on the other side with a torque limiting feature projecting axially from each small diameter lip.
