Magnetic safety gate latch
First Claim
1. A magnetic safety gate latch assembly comprising:
- a first subassembly comprising;
a pool latch tube having a vertical major axis, the pool latch tube comprising a top end and a lower end;
a lift mechanism coupled to the top end of the pool latch tube;
a shaft vertically oriented within the pool latch tube, an upper end of the shaft coupled to the lift mechanism, and a lower end of the shaft comprising a helical thread;
a magnet housing to house a magnet, the magnet housing coupled to the helical threading of the shaft; and
a bottom cover coupled to the lower end of the pool latch tube and enclosing the magnet housing, the bottom cover comprising an aperture on a vertical side facing a latch pin housing, the aperture positioned to expose the magnet; and
a second subassembly comprising;
the latch pin housing;
a ferromagnetic latch pin; and
a magnetic latch pin guide coupled to the latch pin housing and slidably enclosing at least a portion of the latch pin.

Abstract
Magnetic safety gate latch assembly including a first subassembly and a second subassembly. The first subassembly includes: a vertically-oriented pool latch tube; a lift mechanism coupled to the top end of the pool latch tube; a shaft vertically oriented within the pool latch tube, coupled to the lift mechanism, and having a lower end including a helical thread; a magnet and magnet housing, the magnet housing coupled to the helical threading of the shaft; and a bottom cover coupled to the lower end of the pool latch tube and enclosing the magnet housing, the bottom cover including an aperture on a vertical side facing a latch pin housing, the aperture positioned to expose the magnet. The second subassembly includes the latch pin housing; a ferromagnetic latch pin; and a magnetic latch pin guide coupled to the latch pin housing and slidably enclosing at least a portion of the latch pin.

14. A method to operate a magnetic safety gate latch assembly, comprising the steps of:
-
lifting a lift mechanism in order to produce a linear motion; transforming the linear motion to a rotational motion; rotating a magnet by use of the rotational motion; breaking a magnetic attraction between the magnet and a ferromagnetic latch pin; retracting the ferromagnetic latch pin.
