Abstract: Interlocking modular tile frames may be used to lay and fix tile patterns without requiring a substrate adhesive (thin-set mortar) or grout. Tile frames may comprise integrated segments joined by mechanical interconnection components or a whole. A tile frame forms a rigid or semi-rigid enclosure to hold at least one hard tile within its interior. Each segment has an upside-down T-shape cross-section comprising a column and base. The columns, which frame the held tile, eliminate the need for grout. The inserted tile rests on the base of each segment while being held in place by a column along each edge. One or more mechanical interconnections are located at the base of each enclosure to couple adjacent frames together. Stain-resistant materials such as but not limited to polyethylene, polycarbonate, polyvinyl chloride (PVC), polypropylene (PP), acrylic, ABS (acrylonitrile butadiene styrene), nylon, rubber, or a combination thereof, can be used for the frames.
