Abstract
A magnetic door latch assembly includes a magnetic receiver mountable in a door and a latch subassembly mountable in a door jamb. The latch subassembly includes at least one spring-loaded bolt magnetically drawn to the magnetic receiver such that, when the door is closed, the at least one spring-loaded bolt automatically extends to engage the magnetic receiver to maintain the door in a closed state. A spring-loaded depressible button is actuated to drive the at least one spring-loaded bolt apart from the magnetic receiver to allow the door to open. In embodiments, the magnetic door latch is configured for use with a wardrobe door in an aircraft interior application.
Claims17
A magnetic door latch assembly, comprising:
- a receiver subassembly mountable in a door, the receiver subassembly including:
- a receiver;
- a first receiver magnet mounted in the receiver;
- and
- a second receiver magnet mounted in the receiver;
- and
- a latch subassembly mountable in a door jamb, the latch subassembly including:
- a bolt block;
- a first spring-loaded bolt slidably mounted in the bolt block;
- a first pin mounted to the first spring-loaded bolt;
- a first bolt magnet mounted in the first spring-loaded bolt;
- a second spring-loaded bolt slidably mounted in the bolt block;
- a second pin mounted to the second spring-loaded bolt;
- a second bolt magnet mounted in the second spring-loaded bolt;
- a spring-loaded depressible button;
- and
- a button cam mounted to the spring-loaded depressible button, the button cam configured to interact with the first and second spring-loaded bolts;
- wherein, in use:
- in a closed state of the door, the first and second spring-loaded bolts are engaged with the receiver via magnetic attraction between the respective first and second receiver magnets and the first and second bolt magnets;
- and
- pressing the spring-loaded depressible button causes the button cam to interact with the first and second pins to move the first and second spring-loaded bolts out of engagement with the receiver to allow the door to open.
A door assembly, comprising:
- a door subassembly, including:
- a door;
- a receiver mounted in the door;
- and
- at least one receiver magnet mounted in the receiver;
- and
- a latch subassembly mountable in a door jamb, the latch subassembly including:
- a bolt block;
- at least one spring-loaded bolt slidably mounted in the bolt block;
- at least one bolt magnet mounted in the at least one spring-loaded bolt;
- a spring-loaded depressible button;
- a button cam mounted to the spring-loaded depressible button, the button cam configured to interact with the at least one spring-loaded bolt;
- and
- at least one pin mounted to the at least one spring-loaded bolt;
- wherein, in use:
- in a closed state of the door, the at least one spring-loaded bolt is engaged with the receiver via magnetic attraction between the at least one receiver magnet and the at least one bolt magnet;
- and
- pressing the spring-loaded depressible button causes the button cam to interact with the at least one pin to move the at least one spring-loaded bolt out of engagement with the receiver to allow the door to open.
A magnetic door latch assembly, comprising:
- a magnetic receiver mountable in a door;
- and
- a latch assembly mountable in a door jamb, the latch assembly including two spring-loaded bolts that are magnetically drawn to the magnetic receiver, and the latch assembly including a button cam mounted to a spring-loaded depressible button configured to interact with two transverse pins mounted on the respective two spring-loaded bolts to, when the spring-loaded depressible button is pressed, move the two spring-loaded bolts out of engagement with the magnetic receiver to allow the door to open;
- wherein, when the door is closed, the two spring-loaded bolts automatically magnetically attract to the magnetic receiver such that the two spring-loaded bolts extend from the latch assembly to engage the magnetic receiver;
- and
- wherein, when the door is open, the two spring-loaded bolts automatically withdraw into the latch assembly.
