Portable dance floor panel with floating magnet retention system

A portable dance floor system comprising a plurality of floor panels removably couplable together to form a dance floor assembly, each floor panel comprising:

• a) a honeycomb core;
• b) a perimeter frame circumscribing the core, the frame comprising an extrusion with an outwardly facing channel with an outward facing opening, and an elongated cavity behind the outwardly facing channel;
• c) an upper layer extending over the core and over substantially all of the frame;
• d) a lower layer extending under the core and under substantially all of the frame;
• e) the core and the perimeter frame being sandwiched between the upper and lower layer;
• f) a dance floor surface disposed over the upper layer and substantially covering the frame;
• g) a plurality of bores each wider than the outwardly facing channel and each extending from a bottom of the outwardly facing channel to short of the outward facing opening defining a pair of opposing lips extending inward over the bore to form a reduced width with respect to the bore;
• h) a plurality of magnets each disposed in a different one of the plurality of bores;
• i) the plurality of magnets each having a length extending from the pair of lips into a respective bore in the bottom of the outwardly facing channel;
• j) a retaining strip disposed in the elongated cavity and holding the plurality of magnets in the plurality of bores between the retaining strip and the outwardly facing opening;
• k) the retaining strip and the extrusion being non-ferrous;
• and
• l) the plurality of magnets having a diameter smaller than a diameter of the plurality of the bores, or the plurality of magnets having a length shorter than a distance from the outwardly facing opening to the retaining strip, or both, such that the plurality of magnets are movable within the plurality of bores.
