The peripheral side is defined about a perimeter of the paver and joins the bottom and top surfaces. The peripheral side defines a peripheral edge displaced from the top surface and the bottom surface that traverses the perimeter of the body along the peripheral side. The edge is adapted to engage a complementary edge on a peripheral side of an adjacent paver, such that the pavers interlock when a vertical force is applied to the paver. In another aspect, a masonry wall unit is provided for building walls similar in concept to the paver.Type: GrantFiled: March 15, 2013Date of Patent: March 11, 2014Inventor: Robert Pollack

Patent number: 8662788Abstract: Tactile detection embedment plates used in pedestrian walkways releasably aligned by a bracket on at least one of the embedment plates. The bracket can be mated with a bracket on another plate to define a receiver yoke in which a wedge is disposed for a releasable plate assembly connection.Type: GrantFiled: April 23, 2012Date of Patent: March 4, 2014Assignee: MetaDome, LLCInventor: Duane F.

Patent number: 8609215Abstract: A surface covering comprises multiple units adapted to mate with one another and cover a surface. Each said unit comprises at least one primary rotational tessellation element that defines the sides of the unit, has an irregular configuration, includes a face having molded surface irregularities or variations therein, and has at least two pairs of irregularly shaped sides. Preferably, gaps of variable width are defined between visible edges of adjacent units in the surface covering. The surface covering has a natural appearance such that a repeating pattern is not readily apparent. A structural wall unit system is also provided.Type: GrantFiled: September 25, 2012Date of Patent: December 17, 2013Assignee: Keystone Retaining Wall Systems LLCInventor: Thomas S. Riccobene

Publication number: 20130302088Abstract: A paving stone for interlocking with similar adjacent paving stones, having a rectangular block shape. Three single spacers and three spacer pairs extend from the paving stones' lateral surfaces. Each single spacer and each spacer of the spacer pairs have a crest positioned a distance D1 from the lateral surface. Two of the spacer pairs and two of the single spacers are respectively positioned opposite one another on the long lateral surfaces. One of the spacer pairs and one of the single spacers is positioned on the short lateral surfaces. When used with other paving stones having the same features, the single spacers of one paving stone are positioned in troughs of the spacer pairs of another paving stone to provide a structural interlock and create narrow joints between adjacent paving stones. Multiple paving stones can be aligned in multiple configurations, such as herringbone, runner bond, and basketweave patterns.Type: ApplicationFiled: May 14, 2012Publication date: November 14, 2013Inventor: Harvey Penshorn

Publication number: 20130279979Abstract: The disclosure provides, among other things, a paver that includes a body having a top surface, a bottom surface opposite the top surface, and a peripheral side. The peripheral side is defined about a perimeter of the paver and joins the bottom and top surfaces. The peripheral side defines a peripheral edge displaced from the top surface and the bottom surface that traverses the perimeter of the body along the peripheral side. The edge is adapted to engage a complementary edge on a peripheral side of an adjacent paver, such that the pavers interlock when a vertical force is applied to the paver. In another aspect, a masonry wall unit is provided for building walls similar in concept to the paver.Type: ApplicationFiled: March 15, 2013Publication date: October 24, 2013Inventor: Robert Pollack

Patent number: 8545127Abstract: A multi-layer rig mat system and a method for implementing the rig mat system is provided. The rig mat system has a rig mat formed by interconnecting a plurality of panels in an edge-to-edge arrangement and one or more barrier layers placed between the rig mat and the terrain. The barrier layer prevents contamination of the terrain below the rig mat by water and other undesirable fluids seeping through gaps or discontinuities in the rig mat. The barrier layer also prevents heat transmission from the rig mat to the terrain below the rig mat.Type: GrantFiled: June 7, 2011Date of Patent: October 1, 2013Inventors: Leonard Bleile, Jared Michael Bathelt, Brian Matthew Stasiewich
