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 comprising a user-actuated lid coupled to the top end of the pool latch tube;
a pullable and rotatable shaft vertically oriented within the pool latch tube, an upper end of the shaft rigidly coupled to the lift mechanism, and a lower end of the shaft comprising a shaped base;
a magnet housing to house a magnet, the magnet housing at least partially enclosing the shaped base, the magnet housing comprising an upper wall having an aperture to cooperatively engage with the shaped base; 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
A magnetic safety gate latch assembly and method of operation. The assembly includes: a pool latch tube, a user-actuated lid coupled to the top end of the pool latch tube; a rotatable shaft within the pool latch tube, an upper end of the shaft rigidly coupled to the lid, and a lower end of the shaft including a shaped base. The assembly further includes a magnet housing that at least partially encloses the shaped base and includes an aperture to cooperatively engage with the shaped base. The assembly further includes a bottom cover coupled to the lower end of the pool latch tube and enclosing the magnet housing, the bottom cover including an aperture facing a latch pin housing, the aperture positioned to expose a magnet. The assembly further includes a ferromagnetic latch pin and housing, and a magnetic latch pin guide slidably enclosing the latch pin.

13. A method to operate a magnetic safety gate latch assembly, comprising the steps of:
-
lifting a lift mechanism coupled to a shaped base; engaging the shaped base with a magnet housing, the magnet housing comprising an aperture to cooperate with the shaped base; rotating the lift mechanism in order to rotate the magnet housing; changing a magnetic force between a magnet in the magnet housing and a ferromagnetic latch pin; and retracting the ferromagnetic latch pin in order to unlock the magnetic safety latch assembly. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
