Abstract
A magnet holder insert comprising a magnet and magnet holder housing designed with internal wall features capable of keeping the magnet properly positioned in the holder device, and external wall features capable of keeping the magnet holder device securely mounted in the finished part. The internal and external fastening elements of the magnet holder housing are designed in such a way as to promote rapid and secure assembly of both the magnet device and the finished part. The exposed surface of the magnet holder device can be configured with flat or dome shaped exposed contact surfaces, depending on how secure or flexible the magnetic joining feature is intended, capable of attaching to another magnet device or a material susceptible to magnetic attraction.
Claims5
A method of manufacturing an article having magnets embedded in it comprising:
- forming a magnet receiving cavity in said article;
- providing a plastic magnet holder for firmly holding a magnet and for insertion of said plastic magnet holder, with a magnet held firmly in place therein, into said magnet receiving cavity in said article, said magnet holder being dimensioned to fit tightly into said magnet receiving cavity, said plastic magnet holder comprising:
- a plastic housing having a top wall, a side wall or walls depending downwardly from said top wall defining an open interior in said housing, and an open bottom, such that a magnet can be inserted up into said interior of said housing;
- the interior surface of said side wall or walls including at least one interior retainer projecting inwardly into said interior of said housing at a distance below said top wall sufficient to accommodate and retain firmly in place a magnet located between said at least one interior retainer and said top wall;
- said at least one interior retainer projecting inwardly a distance which extends sufficiently far beyond the outer dimensions of the magnet to be placed in said housing that the magnet has to be forced past said at least one interior retainer in order to position and hold it firmly in place between said at least one interior retainer and said top wall;
- the dimensions of said interior space of said housing being slightly greater than the dimensions of a magnet to be located therein, and said at least one interior retainer including a space to either side, such that air is allowed to escape from said interior of said housing past the perimeter of the magnet as it is forced over said at least one interior retainer;
- inserting a tight fitting magnet into said magnet holder by forcing it past said interior retainer whereby said magnet is retained in said magnet holder;
- and forcing said magnet holder and retained magnet into said magnet receiving cavity thereby embedding said plastic magnet holder and its retained magnet in said article.
