Abstract:
An irregularly-shaped building unit includes a front surface, a rear surface opposite of the front surface, and an outer contour surface that extends generally perpendicularly from the front surface to the rear surface. The outer contour surface is irregularly shaped. A plurality of mating sides are disposed on the outer contour surface, where at least two mating sides intersect with a major axis, and at least two mating sides intersect with a minor axis. The major axis and the minor axis are generally perpendicular to each other. Each mating side is a centered rotation about the respective axis that the mating side intersects with.
Abstract:
An impact absorption panel is adapted for playground use and comprises a panel section and a plurality of projections. The panel section is defined by a top surface and a bottom surface. The plurality of projections extend from the bottom surface of the panel section. The plurality of projections have a first stage and a second stage. The first stage is configured to collapse initially when subjected to an impact load. The second stage is configured to provide greater resistance to the impact load than the first stage. The panel section is configured to provide greater resistance to the impact load than the first and second stages. The first stage can also be distinguished from the second stage by virtue of having a comparatively smaller volume.
Abstract:
Multiple polymeric panels molded as a rigid integral body having a planar top surface and a bottom grid structure are interlocked together mechanically along side edges. Each side edge has alternating upwardly and downwardly facing steps with concave dimples on one and mating convex projections on the other for securely interlocking adjacent panels to each other. The steps of adjacent panels interlock with each other to form a complete floor system. The multiple polymeric panels can be molded to simulate flooring materials such as brick or overlaid with sections of linoleum, carpet, synthetic grass, tile or wood flooring. Alternately, the assembled panels can be covered with a sheet of decorative material.
Abstract:
A specially designed beveled edge (26) guides tile interlocks (14) into place and holds them in place during assembly, thereby facilitating ease and speed of interlocking tile (10) assembly for tight fitting interlocks which actually lock contiguous tiles together. Assembly time for an entire surface using such interlocking tiles is greatly reduced in comparison to comparable prior art interlocking tiles with no diminution in interlocking quality or tile wear.
Abstract:
A permeable surface covering unit comprises a top surface and at least two pairs of irregularly shaped mating sides, one or more passageways extending downwardly from the top surface, and at least one under channel connected to the passageways for retaining liquid, such as storm water. The sides of the unit preferably define an irregular rotational tessellation element. The passageways may comprise gaps or side cavities between units and/or core cavities or other passageways within the unit. Optional undercuts may be provided in the core cavities. Pervious material plugs are cast into the cavities extending into the channel or undercut. Thereby the plug is locked into the cavity like a rivet and resists being dislodged by mechanical or hydraulic forces. A permeable surface embodiment comprises a combination of pervious and impervious units, wherein the ratio of permeable to impermeable units and resulting surface absorption rate may be adjusted.
Abstract:
Offenbart ist ein demontierbarer Outdoor-Sportbodenbelag, der aus einer Vielzahl von Bodenelementen besteht, die ihrerseits eine Schicht aus Lastverteilungselementen haben, auf denen eine Deckschicht aufgebracht ist. Diese Bodenelemente liegen auf einer Dämpfungsschicht auf, wobei die Lastverteilungselemente, die Deckschicht und die Dämpfungsschicht wasserbeständig ausgeführt sind.
Abstract:
Multiple polymeric panels (10) molded as a rigid integral body having a planar top surface (11) and a bottom grid structure (25) are interlocked together mechanically along side edges (20) (12). Each side edge has alternating upwardly (14) and downwardly (22) facing steps with concave dimples (18) on one and mating convex projections (24) on the other for securely interlocking adjacent panels to each other. The steps of adjacent panels interlock with each other to form a complete floor system. The multiple polymeric panels can be molded to simulate flooring materials such as brick or overlaid with sections of linoleum, carpet, synthetic grass, tile or wood flooring. Alternately, the assembled panels can be covered with a sheet of decorative material.
Abstract:
An artificial turf system having a bottom layer comprised of a plurality of pads constructed from a cross-linked, closed cell, high-density foam, a top layer of synthetic fibers disposed upon the bottom layer to provide a synthetic grass surface, and an infill layer installed upon the top layer wherein the bottom layer functions to provide shock absorbing characteristics to the artificial turf system as well as to evacuate water laterally.
Abstract:
A multi-layered sports playing field (1) including a top layer (3) made of substantially artificial material simulating a natural playing surface such as grass (5) and a padding layer (7) positioned between the top layer (3) and the base or dirt layer (9). The padding layer (7) is made of a plurality of discrete beads (11) of substantially elastic, resilient material (e.g., foam) with portions of adjacent beads (11) abutting one another and other portions being spaced from each other. Substantially all of the adjacent beads (11) are preferably integrally joined (e.g., glued, fused) together at their abutting portions. The padding layer (7) is very porous and breathable and preferably includes feet members (17) supporting the main body (31) of the padding layer (7) above the base or dirt layer (9) to create a water channel of interconnected portions (25) to enhance Water drainage to the sides of the field (1).
Abstract:
This invention refers to a modular construction system that provides structures utilizable in the manufacture of bases for pavements, slopes, canals, walls, arches, bridges, etc. More specifically, a flexible structure is obtained and formed by the articulated and indissoluble union of a multiplicity of identical modular units (40, 41) that have articulated, unbreakable joints - although with free spaces between the units - in such a way that when a weight is placed in any area of said flexible structure, a part of it is immediately distributed to the adjacent areas, said structure thus resulting in a stress distribution system, being flexible, articulated, and indissoluble. The distribution of stresses occurs both in the horizontal and the vertical direction. If desired, two or more structures can even be placed one on top of the other, duly articulated between each other, with a separating layer between each one of them, by means of latch pins (70) such as to allow the structure to be flexible, functioning in a manner similar to how a single structure functions.
