Abstract
In general, an electronic lockset with automatic handing determination is disclosed. The lockset may be mounted to a door, and the lockset may automatically determine a handing of the door to properly lock and unlock the door. Various techniques are disclosed for determining handing, including analyzing an image of the door, selecting an image of the door, deriving handing based on data captured when swinging a door, determining a location of an external reference point, determining a rotational location of aspects of a latch assembly, performing another technique, or a combination of the described techniques.
Claims20
An electronic lockset mounted to a door, the electronic lockset comprising:
- a latch assembly comprising a drive shaft;
- a reference element rotationally coupled with the drive shaft;
- a sensor;
- a processor;
- and
- memory storing instructions;
- wherein the instructions, when executed by the processor, cause the electronic lockset to:
- detect, using the sensor, a rotational position of the reference element;
- based on the rotational position of the reference element, determine a handing of the door;
- wherein determining the handing of the door comprises (i) determining that the door is right-handed after determining that the rotational position of the reference element is in a rotational position that is exclusive to a right-handed door;
- or (ii) determining that the door is left-handed after determining that the rotational position of the reference element is in a rotational position that is exclusive to a left-handed door.
A method for determining a handing of a door, the method comprising:
- by an electronic lockset:
- detecting, using a sensor, a rotational position of a reference element rotationally coupled with a latch assembly;
- and
- automatically determining that the door is right-handed by determining that the rotational position is exclusive to right-handed doors, wherein the reference element cannot be in the rotational position for left-handed doors.
A system comprising:
- an electronic lockset;
- and
- a mobile device;
- wherein the mobile device is configured to:
- display, via a graphical user interface of a mobile application, a first image of a left-handed door with a lockset positioned on a first side of the door;
- display, via the graphical user interface of the mobile application, a second image of a right-handed door with the lockset positioned on a second side of the door;
- display, via the graphical user interface of the mobile application, instructions for a user to select the first image or the second image as representing an exterior or an interior of the door ;
- receive, via the graphical user interface of the mobile application, a selection of the first image or the second image from the user;
- based on the selection of the first image or the second image, automatically identify the handing of the door;
- and
- send the handing to the electronic lockset.
