Abstract:
The invention relates to an artificial stone floor element with a basic shape that corresponds to the combination of a plurality of square basic elements, especially to an angular floor element. The floor element includes projections and recesses along its peripheral sides of the basic element when seen from the centre of the respective top face of the basic element is substantially point-symmetric with respect to its mid-point. The floor element in further embodiments includes a profile that consists of three projections and three recesses.
Abstract:
A modular surfacing mat that includes a base mat, a top mat secured to the base mat with an adhesive, and a top coat applied to the top of the top mat to form a protective finish. The top coat may be any coating that provides a protective top finish on the mat, and is preferably a polyurea or polyurethane. The top coat may include a colorant. The top mat is preferably at least partially made from rubber. For example, recycled rubber may be used. The adhesive that bonds the top mat to the base mat is preferably a polyurethane or a polyurea. The base mat is preferably made from a cellular foam structure. For example, cellular foam strucutre may be closed cell polyethylene foam nuggets fused together in a crosslinked matrix.
Abstract:
A heatable module for use in constructing a pathway for traffic comprises a base member having a perimeter edge. A top plate is securable to the base member in overlying relation to the top surface of the base member. An electrically powerable heater member retained by at least one of the base member and the top plate. To form a heatable pathway for traffic, the modules are placed in perimeter-edge-to-perimeter-edge relation one to the next.
Abstract:
A heatable pathway system for traffic comprises a first module having a first electrically powerable heater member and a second module having a second electrically powerable heater member. The first module and the second module are each installable in place to form a heatable pathway system for traffic. An electrical power controller circuit has a first power output connected in power supplying relation to the first electrically powered heater member and a second power output connected in power supplying relation to the second electrically powerable heater member. The electrical power controller circuit is operable to provide electrical power from the power outputs in a heating cycle that comprises a first heating sub-cycle and a second heating sub-cycle such that, during a heating cycle, a first one of the electrically powerable heater members is on and a second one of the electrically powerable heater members is off during the first heating sub-cycle, and the second electrically powerable heater member is on and the first electrically powerable heater members is off during the second heating sub-cycle.
Abstract:
A permeable surface covering unit comprises a top surface, a bottom surface and at least two pairs of sides. A cavity is formed in the unit from the top surface to the bottom surface, and has side walls. The cavity may be a side cavity between units and/or a core cavity within the unit. An undercut is provided in the cavity. Pervious material plugs fill the cavity and extend into the undercut. Thereby the plug is locked into the cavity like a rivet and resists being dislodged by mechanical or hydraulic forces.
Abstract:
What is disclosed is removable outdoor sport flooring consisting of a plurality of floor elements that in turn have a layer of load distribution elements on which a cover layer is applied. The floor elements lie on a damping layer, the load distribution elements, the cover layer and the damping layer being implemented so as to be water-resistant.
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 dual-unit paving system for covering a surface is provided. The system comprises pairs of first and second units. For each pair, the first and second unit have different respective shapes and sizes, and are configured to be matingly engageable for forming a hexagonal assembly having six, non-linear sides. The hexagonal assembly allows forming rotational tessellations. The first and second units are also shaped and configured to be matingly engageable so as to form horizontally aligned tessellations, and also vertically aligned tessellations.
Abstract:
An interlocking building block, and procedure for constructing the same, having a planar locking mechanism and a spatial locking mechanism. The planar locking mechanism being a three-clawed piece built around an equilateral triangle with protruding arms and grooves corresponding to a circular arc. The protruding claws are rotated on a plane around a center of rotation. These align with grooves of another three-clawed piece to offer a locking mechanism, where the center point of the circular arc is identical to the center of planar rotation. The spatial locking mechanism may have a hexagonal prism placed next to the three-clawed piece and connected to the corners of the equilateral triangle, into which the three-clawed piece is placed so that the protruding claws extend beyond the hexagonal prism, or the spatial locking mechanism consists of protrusions ensuring a groove/taper connection and connecting grooves, so that each piece contains protrusions and grooves.
Abstract:
The present document describes a padding layer for a multi-layered sports playing field. Various improvements are proposed for enhancing athlete's safety, surface hardness, water drainage, heat management, ease of assembly/installation, durability/longevity, uniformity, resistance to change in weather according to seasons, and stability. The improvements include: matching (multiple-wise) of spacing between rows of backstitches of the top layer and the drainage channels on top surface of the padding layer; a slit in the external tab portion of the padding layer panel, a slit near the lateral part of the tab or blank portion providing a hinging effect thereto, and/or protrusions at various positions on the tab or blank portions to account for change in size of the padding layer panel; drainage holes within the drainage channels; and various configurations of drainage channels on the bottom surface of the padding layer to improve evacuation of water toward the sides of the playing surface.
