Abstract:
An impact-absorbing assembly includes a covering layer being one or more of artificial turf, rubber mats, polymer mats, short pile carpeting, particulate infill, wood chips, and ground rubber chips. Also included is a layer of underlayment panels positioned beneath the covering layer. The panels have a panel section with a plurality of drain holes formed therethrough. A top surface of the panels is configured to support the covering layer. A bottom surface of the panels has a plurality of bottom projections that cooperate to define bottom channels suitable to permit water flow across the bottom surface, the bottom channels being in fluid communication with the panel drain holes. The bottom projections define a first spring rate characteristic that is part of a first stage and a second spring rate characteristic is part of a second stage, the first stage having a smaller volume of material than the second stage.
Abstract:
Reversible floor mats having two layers bonded together at an undulating surface are described. Each layer has a generally non-constant across over its width and length. The combined thickness of the two layers is generally constant over its width and length. The layers have different colors and/or different surface textures to provide different working surfaces.
Abstract:
A connection surface disposed on a face of a structural unit comprises a first segment having a three dimensional surface profile including a plurality of positive outer surfaces extending outwardly along a normal direction from a plane and a plurality of negative outer surfaces extending inwardly along the normal direction from the plane, wherein at least two of the plurality of positive outer surfaces are separated from one another along both vertical and horizontal directions and at least two of the plurality of negative outer surfaces are separated from one another along vertical and horizontal directions. A second segment opposes the first segment with respect to an axis, wherein the second segment is a substantial reflection of the first segment across the axis, but reversed along the normal direction.

Abstract:
Positive interlocking revetment blocks adapted for providing a matrix having one or more linear borders. Disclosed are border blocks that each have one side without an interlocking arm or socket, thus providing part of a linear side of the matrix. Disclosed also are corner blocks that each have two sides without an interlocking arm or socket, thus providing part of linear sides to the matrix. Interior interlocking blocks are constructed for interlocking with the border blocks and the corner blocks, and with each other to form a matrix that has one or more linear sides. Also disclosed is a universal mold having removable arm members and socket members that can be configured to fabricate the border blocks, the corner blocks and the interior blocks.
Abstract:
Floor mats comprising two layers bonded together with an undulating boundary between them. The surface color and/or surface texture of the first layer being different from the surface color and/or surface texture of the second layer. The mats having an interlocking periphery boundary adapted so the mats can be interlocked with adjoining mats to form a continuous planar mat flooring.
Abstract:
An underlayment panel includes a top surface and a bottom surface. A plurality of projections define drainage channels. A plurality of drain holes arranged through the panel provide fluid communication between the top surface and the bottom surface.
Abstract:
A modular flooring system includes a plurality of floor tiles situated about a ground surface, with each floor tile having a substantially-flat top surface and a connection interface with opposing engagement surfaces. The flooring system also includes a plurality of removable bridge connectors, with each of the bridge connectors having a plurality of tile interfaces, and with each tile interface having complimentary engagement surfaces configured to engage with the opposing engagement surfaces of the connection interfaces. The tile interfaces of the bridge connectors couple to the respective connection interfaces of any adjacent floor tiles to restrain the relative vertical movement between the adjacent floor tiles while facilitating controlled relative lateral movement between the floor tiles.
Abstract:
A paving system for paving or flooring includes a top layer of a plurality of paving elements, and an underlayment support layer of a polymeric material configured into panels. The panels are suitable to support the paving elements, the panels having a generally planar support surface and a recovery characteristic such that a deformation from a concentrated compressive load applied for a short duration returns the support surface to a generally planar condition.
Abstract:
Interlocking building block, paving unit, tile or toy element, one part of which is a piece offering at least one planar locking mechanism, and the other part of which is an element offering at least one spatial locking mechanism. The element is characterized by the piece providing the planar locking mechanism being a three-clawed piece (21) built around an equilateral triangle (1) with protruding arms (22) and grooves (23) corresponding to their circumference arranged in a circular segment (23). The protruding claws (22) are rotated on a plane around a center of rotation (30). These align with the grooves (23) of another three-clawed piece (21) to offer a bayonet type locking mechanism, where the center point of the circular segment (12) is identical to the center of planar rotation (30). The element providing spatial locking is either comprised of at least one hexagonal prism (20) placed next to the three-clawed piece (21) and connected to the corners of the equilateral triangle (1), into which the three-clawed piece (21) is placed so that the protruding claws (22) extend beyond the hexagonal prism (20) to the same extent that the grooves (23) extend into the base area of the hexagonal prism (20), or the element providing for spatial locking built at the circumference of the three-clawed piece (21) consists of protrusions (28) (tapers) ensuring a groove/taper connection and connecting grooves (29), so that each piece contains protrusions (28) (tapers) as well as grooves (29). The invention also includes the procedure of constructing the elements.
