Abstract

A magnetic gate latch opens and secures closed a portal or gate employing improvements that favors continued smooth operation and that minimizes freeze-up during winter. The improvements enable confined movement of the locking pin within a hollow cavity at the bottom of a lifting rod. The locking pin includes a flange extending outward from around the locking pin to divide the locking pin into an upper portion that slides within the hollow cavity and a lower portion that confines a spring. An elliptical aperture in the upper portion surrounds a rivet that limits locking and unlocking movement of the locking pin. The spring pushes up on the flange to bias the locking pin in an upward, unlocked position and hold it there after the gate is opened.

Claims

1. A magnetic gate latch to open and secure closed a portal or gate, the magnetic gate latch comprising:

a main body assembly for vertical attachment to a post adjacent to the gate, the main body assembly comprising;

an upper section comprising a pull knob at a top of the upper section;

and a lower section comprising a catcher and a locking pin; and

a rod connected to the pull knob, the rod extending downward so that a portion of the rod defines a hollow cavity;

a secondary assembly for attachment to the gate, the secondary assembly comprising;

a permanent magnet within a magnet housing that engages the catcher when the gate closes such that when the magnet housing strikes against the catcher, the locking pin is drawn out of the main body assembly by the permanent magnet to latch the gate; and

a gate bracket that secures the secondary assembly to the gate;

wherein the locking pin comprises;

a flange extending outward from around the locking pin to divide the locking pin into an upper portion and a lower portion, wherein;

the upper portion defines an elliptical aperture; and

the lower portion defines a location of a spring surrounding the locking pin, the spring acting on the flange to bias the locking pin in an upward direction;

wherein the hollow cavity is configured to slidably receive therewithin the upper portion of the locking pin;

wherein the rod further defines a rivet hole through the portion of the rod defining the hollow cavity; and

wherein the magnetic latch further comprises a rivet extending through the rivet hole and through the elliptical aperture of the locking pin.
