A connectable floor tile has a flexible, top layer, a flexible, middle layer or core, and a flexible, bottom layer. The combination of the top layer and bottom layer has sidewall portions having opposed marginal perimeter portions. The sidewall portions have an interior sidewall surface that abuts the middle core. The central portion defines a land that has a support surface. A plurality of spaced-apart cleats extend upwardly to respective distal surfaces and define channels therebetween.

The invention discloses a wooden floor with high utilization, a connection assembly, and a connection structure of a wooden floor with high utilization and a connection assembly. The wooden floor with high utilization includes a floor body. The floor body defines a first groove on one side surface thereof in a horizontal direction. The floor body defines a second groove on the other side surface thereof in the horizontal direction. The first groove and/or the second groove define a notch. The floor body of the present invention is merely required to define grooves on two sides thereof, and is not necessary to provide a protruding male buckle, as long as the first groove or the second groove is connected with a male buckle of the connection assembly, so that wood can be saved, thus increasing a utilization rate of the wood. The wood saved by a single piece of wood floor is limited, but many a little makes a mickle. Moreover, two adjacent floor bodies can be connected by the groove to reserve a certain gap therebetween according to need, which can increase the air permeability of the floor. The use of wood can be greatly saved to protect the ever-decreasing trees, and benefit the human society.

Surface coverings, such as floor coverings, with an interlocking design are described. Methods of making the surface coverings are further described. A plank including a resilient composite sheet having four sides, an upper surface, a lower surface, and an overall thickness, and said composite sheet comprising at least one base layer, wherein said at least one base layer comprising at least one polymeric material and at least one filler, wherein opposite sides of the composite sheet comprise a first tongue on a first side and a first groove on the opposite second side, wherein the first tongue and first groove have complementary shape to each other to be interlockingly engageable with a corresponding groove or tongue on an adjacent floor plank.

A covering element includes a carrier plate having a mineral material, the carrier plate formed as a flat mineral carrier plate with a content of cement larger than 35 percent by volume and with a content of natural fibers of 1 to 40% by volume. The carrier plate has a thickness between 3 and 15 mm and carries a polymer-containing decor layer on a front side of the carrier plate. Complementary recesses and protrusions are provided on opposing lateral edges of the carrier plate of the covering element, such that in an assembled condition of two or more covering elements the complementary recesses and protrusions engage with each other, wherein a portion of a polymer contained in the polymer containing decor layer penetrates into the carrier plate.

Fall protecting flooring element that comprises a flat rectangular body of a resilient Material having a lower face, an upper face, four sides, patterns at its four sides that enable interlocking several similar flooring elements by form-fitting connections. Respective short straight corner sections are provided that constitute a part of the side of the concerned side. The patterns comprise alternating sequence of connection tabs and connection recesses. The connection tabs have identical profiles but inverse of the profiles of the connection recesses. A plurality of fall protecting floor elements can be connected together to form a flooring.

In one aspect of a reinforced tile, the reinforced tile may be configured for use with a support structure that may be engaged with a top portion of a pedestal. The reinforced tile may be configured with a substrate adhered to a back side of a tile, and the substrate may be comprised of a fiberglass material. A groove may be formed along at least one edge of the reinforced tile, and the groove may be positioned at the interface of the tile and substrate. The support structure may be formed with a generally vertical spine having at least one rail extending outward from a distal end thereof. The spine and rail(s) may be configured to secure one or more reinforced tiles, wherein one or more rails may be positioned within a groove formed in the reinforced tile.

A covering element includes a carrier plate including at least mineral particles pressed together to a plate by a polymeric adhesion agent, complementary recesses and protrusions formed, respectively, on opposing lateral edges of the carrier plate, so in an assembled condition of two or more covering elements, the complementary recesses and protrusions can engage with complementary protrusions and recesses, respectively, of another of the two or more covering elements, a decor layer including a polymer and on a front side of the carrier plate, the decor layer including at least at least one, color pigment-containing, printing layer and a polymer-containing transparent top layer containing polyurethane or acrylic.

Floor panels are provided with a mechanical locking system including a flexible locking element in a locking groove which during a horizontal motion is displaced vertically. A panel system including a plurality of rectangular panels with long and short edges which are mechanically connectable to each other along at least one pair of adjacent edges, said panels each being provided with a tongue and groove formed in one piece with the panels for mechanically locking together said adjacent edges at right angles to the principal plane of the panels, thereby forming a vertical mechanical connection between the panels, said panels being provided with a first locking element at one first edge formed in one piece with the panel and a locking groove at an opposite second edge, the locking groove being open towards a rear side or a front side of the panel.

In one aspect of a tile and support structure, a support structure may be engaged with a top portion of a pedestal. The support structure may be formed with a generally vertical spine having at least one rail extending outward from a distal end thereof. The spine and rail(s) may be configured to secure one or more tiles, which tiles may be formed with a groove on at least one edge thereof, and wherein one or more rails may be positioned within the groove.

A set of subfloor panels including a joint configured to be glued is provided. The joint includes a tongue at a first edge of a first panel and a tongue groove at a second edge of a second panel. The tongue and the tongue groove are configured for positioning of the first panel relative to the second panel in a vertical direction, wherein a lower lip of the tongue groove extends beyond an upper lip of the tongue groove. An element protrudes from the lower lip and an underside of the first edge includes an element groove. The element and the element groove are configured for positioning of the first panel relative to the second panel in a horizontal direction. The lower lip includes a first impact surface, and the first edge includes a second impact surface. The first impact surface is configured to cooperate with the second impact surface.
