Abstract
A magnetic coupler having a housing defining a coupler plane, a magnet assembly positioned at least partially within the housing, the magnet assembly being movable relative to the coupler plane, and a release assembly coupled to the magnet assembly to selectively reposition the magnet assembly relative to the coupler plane based on the angular orientation of the release assembly.
Claims16
A magnetic coupler, comprising:
- a housing defining a coupler plane;
- a magnet assembly positioned at least partially within the housing, the magnet assembly being movable relative to the coupler plane;
- a release assembly coupled to the magnet assembly to selectively reposition the magnet assembly relative to the coupler plane based on the angular orientation of the release assembly, wherein the release assembly comprises a bushing that is rotatable about a rotation axis relative to the housing;
- a cam collar coupled to the housing about the rotation axis, the cam collar defining a helix segment;
- and
- a magnet shaft positioned along the rotation axis and coupled to the magnet assembly on one end and extending through a portion of the housing, the magnet shaft further defining a radially expanded head;
- wherein the radially expanded head is positioned at least partiality within the bushing.

A magnetic coupler assembly, comprising:
- a housing defining a coupler plane;
- a magnet assembly positioned at least partially within the housing, the magnet assembly being movable relative to the coupler plane;
- and
- a release assembly comprising:
- a bushing that is rotatable about a rotation axis relative to the housing, the bushing defining a radial lip;
- a cam collar coupled to the housing about the rotation axis, the cam collar defining a helix segment;
- a magnet shaft defined along the rotation axis and coupled to the magnet assembly on one end and extending through a portion of the housing and defining an expanded head on the other end;
- and
- a pin coupled to the bushing and positioned along the helix segment of the cam collar;
- wherein the radial lip of the bushing is positioned at least partially between the expanded head of the magnet shaft and the housing and rotating the pin about the rotation axis repositions the bushing, magnet shaft, and magnet axially along the rotation axis relative to the coupler plane between an adjacent position and a spaced position.
