Abstract

A deadbolt lock with an interior assembly having a status light indicator. The deadbolt assembly has a bolt movable between an extended position and a retracted position. An interior locking assembly includes a turnpiece configured to move the bolt between its extended position and retracted position, a light, and a detection circuit. The detection circuit is configured to detect when the bolt is in the extended position and actuate the light responsive to detecting that the bolt being in the extended position.

First claim

What is claimed is:

1. A deadbolt assembly comprising:
a bolt movable between an extended position and a retracted position;
an interior locking assembly comprising:
a rose including an interior surface defining an interior cavity and exterior surface on an opposite side of the rose from the interior surface, wherein the rose includes an opening therethrough;
a turnpiece extending from the exterior surface of the rose and being rotatable to move the bolt between the extended position and the retracted position, wherein the turnpiece includes a shank extending into the interior cavity through the opening in the rose;
a magnet disposed in the interior cavity defined by the rose, the magnet being attached to a magnet carrier, the magnet being rotatable with the turnpiece;
a light;
a detection circuit configured to detect when the bolt is in the extended position, the detection circuit comprising a magnetic sensor disposed in the interior cavity and is configured to actuate the light responsive to either: (1) detecting the magnet; or (2) detecting the absence of the magnet;

wherein the magnet is rotatable between a first position corresponding with a position in which the bolt is in an extended position and a second position corresponding with a position in which the bolt is in a retracted position;
wherein the magnet is positioned on the shank to be undetectable by the magnetic sensor in the first position and detectable by the magnetic sensor in the second position.

2. A deadbolt assembly comprising:
a bolt movable between an extended position and a retracted position;
a turnpiece rotatable to move the bolt between the extended position and the retracted position;
a magnet carrier including a magnet, wherein the magnet carrier and the magnet are rotatable with the turnpiece;
a magnetic sensor configured to (1) detect the magnet; or (2) detect the absence of the magnet;
a light; and
a processor electrically coupled with the light and magnetic sensor, wherein the processor is configured to actuate the light responsive to the magnetic sensor either: (1) detecting the magnet; or (2) detecting the absence of the magnet;
wherein the magnet is rotatable between a first position corresponding with a position in which the bolt is in an extended position and a second position corresponding with a position in which the bolt is in a retracted position; and
wherein the magnet is undetectable by the magnetic sensor in the first position and detectable by the magnetic sensor in the second position.

3. A deadbolt assembly comprising:
a bolt movable between an extended position and a retracted position;
an interior locking assembly defining an interior cavity, wherein the interior locking assembly includes:
a turnpiece rotatable to move the bolt between the extended position and the retracted position;
a light;
means for actuating the light responsive to the bolt being in the extended position, wherein the actuating means is entirely disposed in the interior cavity, and wherein the actuating means comprises a magnet coupled to-a shank of the turnpiece, the magnet rotatable with rotation of the turnpiece;

wherein the actuating means includes an electrical device disposed in the interior cavity that is configured to detect when the bolt is in the extended position;
wherein the magnet is rotatable between a first position corresponding with a position in which the bolt is in an extended position and a second position corresponding with a position in which the bolt is in a retracted position;
wherein the magnet is undetectable by the magnetic sensor in the first position and detectable by the magnetic sensor in the second position.
