SELF-CLOSING AND RESETTING LATCH - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240278899 titled 'SELF-CLOSING AND RESETTING LATCH

The abstract describes a self-closing and resetting latch for a cabin door, consisting of a pawl with a protrusion, an over-center spring, a latch hook with recesses, and a frame of the cabin door.

The apparatus includes a pawl with a protrusion that is connected to an over-center spring.
The over-center spring is attached to the frame of a cabin door.
A latch hook is present with a first recess to receive the pawl's protrusion and a second recess for a latch pin when the cabin door closes.

Potential Applications: - This latch system can be used in various types of cabin doors, such as those in aircraft, ships, or other enclosed spaces. - It can also be applied to other types of doors that require a self-closing and resetting mechanism.

Problems Solved: - Eliminates the need for manual closing and locking of cabin doors. - Ensures that the door is securely closed and locked every time it is shut.

Benefits: - Enhances safety and security by automatically closing and locking the cabin door. - Reduces the risk of human error in ensuring that the door is properly closed.

Commercial Applications: - This technology can be valuable in the aviation and maritime industries where safety and security are paramount. - It can also be used in residential and commercial buildings to improve door locking mechanisms.

Prior Art: - Prior art related to self-closing and resetting latches for doors can be found in patents and research related to door locking mechanisms and safety features.

Frequently Updated Research: - Stay informed about advancements in latch technology, door security, and safety features to enhance the effectiveness of this self-closing and resetting latch system.

Questions about self-closing and resetting latch technology: 1. How does the over-center spring contribute to the self-closing mechanism of the latch? 2. What are the potential variations in design for self-closing and resetting latches in different types of doors?
