A construction and methods of assembly and construction of boards, e.g. floor boards, are described. The boards have a peripheral connection arrangement for interconnecting of one board to another, a core layer e.g. made from a wood or fiber based material and a top layer applied to the core layer which may be decorative and may include or provide a wear layer. A further bottom layer may be applied to the underside of the core layer and is designed to be in contact with the floor or an underlay can be applied when in use. The connection arrangement includes interconnecting hooking tongues and corresponding catches which co-operate to produce both vertical and horizontal locking.

An impact damping mat comprises a plurality of layers arranged in a stacked formation. The stacked formation has a total thickness of no greater than 4 and 7/16 inches. The plurality of layers cooperate to provide the impact damping mat with at least one of a coefficient of restitution no greater than 30% and a selected sound reduction characteristic. The selected sound reduction characteristic can be a reduction of a maximum sound level of at least 5 dB from 40 to 63 Hz 1/3 octave bands and at least 13 dB at and above 80 Hz 1/3 octave bands normalized to a conventional inch rollout rubber flooring product.

The present invention relates to a floor tile comprising a base substrate and a laminate layer, wherein the base substrate comprises at least one aligning member on a top surface thereof, the aligning member operable to engage with a complimentary receiver formed in the laminate layer for aligning the laminate layer on the top surface of the substrate.

Floor panels are shown, which are provided with a mechanical locking system comprising tongue and grooves provided with protrusions and cavities which are displaceable in relation to each other and configured such that the protrusions can obtain a vertically unlocked position where they match the cavities and a vertically locked position where the protrusions overlap each other.

A landscaping block having a block body with at least a first side surface, a second side surface, a third side surface and a fourth side surface, and opposed and substantially parallel top and bottom surfaces. The patio block having at least one spacer projection extending outwardly from each of the at least first, second, third and fourth side surfaces. The patio block having at least one spacer locator positioned along each one of the first, second, third and fourth side surfaces. The at least one spacer locator positioned along each side surface has a retaining surface shaped to receive a spacer projection, at least a portion of the retaining surface extending outwardly from the side surface.

A mat unit is formed from at least two layers ultrasonically welded together. Each layer is individually formed from non-vinyl nontoxic thermoplastic elastomer (TPE) material. In ultrasonically joining the two layers together, there is no need to use additional materials, such as adhesive (i.e., chemical attachment) or stitched thread (i.e., mechanical attachment) to form the joint/weld point. Once formed from the two layers, the mat unit has four quadrants and a plurality of longitudinal ribs integrally formed in the first layer positioned in the first and third quadrants, and a plurality of transverse ribs integrally formed in the first layer positioned in the second and fourth quadrants. Additionally, there are a plurality of longitudinal ribs integrally formed in the second layer positioned in the second and fourth quadrants, and a plurality of transverse ribs integrally formed in the second layer positioned in the first and third quadrants.

An impact damping mat comprises a base layer having a base surface with a plurality of protuberances, a damping layer overlying the base layer, a load distribution layer overlying the damping layer and an upper layer overlying the load distribution layer and having a planar top surface. The materials and dimensions of the layers cooperate to provide a selected rebound characteristic and a selected sound reduction characteristic.

Floor panels are shown, which are provided with a mechanical locking system on long and short edges allowing installation with vertical snap folding that could be accomplished automatically without tools and where the short edge locking system has a tongue made in one piece with the panel. The floor panels may have a first and a second connector at the long edges that are configured to obtain a minimum of friction facilitating a displacement, by a spring back force from the bending of a short edge locking strip, of a new panel in a horizontal direction along the long edge during the vertical snap folding action.

Aspects relate to improved floor boards. Certain embodiments may be laid and fixed without the need for fixing with adhesive or nails. In one embodiment, a floor board includes a four-sided surface board connected to a four-sided base board. Further example floor boards includes staggered tongue-shaped hooking tongues for connection of multiple floor boards.
