Securing device and removal tool for use with the securing device

An assembly of a first object and a second object, the assembly comprising:

• a securing device, the securing device comprising a casing having a top end and a bottom end;
• a moveable magnet and a further magnet, the moveable magnet and the further magnet being housed in the casing in which the further magnet is retained in a fixed position, one of the moveable and the further magnets being received by the other of the magnets such that the one of the magnets is disposed in a through passageway of the other of the magnets, and the further magnet and the moveable magnet being oppositely magnetically poled to one another in an initial position of the movable magnet, the movable magnet being slidable relative to the further magnet in a top to bottom direction of the casing between the initial position and a working position in which the moveable magnet is in a magnetically repelling relationship with the further magnet;
• and wherein the first object and the second object are assembled together in the assembly whereby aligned openings of the first and second objects form a passageway in which the casing of the securing device is inserted to extend from one of the first and second objects into the other of the first and second objects such that the bottom end of the casing is seated in position in the assembly for retaining the first object and the second object against separation from one another, the moveable magnet being in its working position forming a magnetic coupling holding the bottom end of the casing in its seated position in the assembly and thereby the casing in the passageway, wherein the magnetically repelling relationship between the moveable magnet and the further magnet assists release of the movable magnet from the magnetic coupling for return of the moveable magnet to its initial position and withdrawal of the securing device from the passageway;
• and wherein the first and the second objects are selected from the group consisting of:
• a digger, mining or excavation tooth and an adaptor for the tooth;
• a digger tooth, cutting edge or wear plate and a mining or excavation bucket for the digger tooth, cutting edge or wear plate;
• and a material handling chute, bin, hopper or bucket and a wear plate for the material handling chute, bin, hopper or bucket.

A method for releasably securing a first object to a second object, comprising:

• providing a securing device for securing the first object and the second object together, the securing device comprising a casing having a top end and a bottom end, a moveable magnet and a further magnet, the moveable magnet and the further magnet being housed in the casing in which the further magnet is retained in a fixed position, one of the moveable and the further magnets being received by the other of the magnets such that the one of the magnets is disposed in a through passageway of the other of the magnets, and the further magnet and the moveable magnet being oppositely magnetically poled to one another in an initial position of the movable magnet, the movable magnet being slidable relative to the further magnet in a top to bottom direction of the casing between the initial position and a working position in which the moveable magnet is in a magnetically repelling relationship with the further magnet;
• assembling the first and second objects together in an assembly whereby openings of the first and the second objects are aligned forming a passageway;
• and positioning the casing of the securing device in the passageway such that the casing extends from one of the first and second objects into the other of the first and second objects such that the bottom end of the casing is seated in position in the assembly to retain the first object and the second object against separation from one another, and the moveable magnet is moved from its initial position to its working position to form a magnetic coupling holding the bottom end of the casing in its seated position in the assembly and thereby the casing in the passageway, wherein the magnetically repelling relationship between the moveable magnet and the further magnet assists release of the moveable magnet from the magnetic coupling for return of the moveable magnet to its initial position and removal of the securing device from the passageway;
• and wherein the first and the second objects are selected from the group consisting of:
• a digger, mining or excavation tooth and an adaptor for the tooth;
• a digger tooth, cutting edge or wear plate and a mining or excavation bucket for the digger tooth, cutting edge or wear plate;
• and a material handling chute, bin, hopper or bucket and a wear plate for the material handling chute, bin, hopper or bucket.
