Latest Patents

Among his latest patents is a ceiling system featuring staked-on connectors. This system includes main runner members and cross members designed with an inverted T-shaped configuration. The outer edges of the flanges are bent upwardly at an angle, creating a beveled edge that gives the flanges the appearance of being substantially thicker than the material used to form them. The cross members incorporate a connecting element, which is preferably a separate component with spacer bumps and a U-shaped tab. This tab serves as a first abutment, while a portion of the element is cut and deformed to create a second abutment surface, allowing for alignment and secure connection of adjacent cross members within the main runner.

Another significant patent is the parallel beam system, which is designed for constructing either horizontal or vertical walls. This system consists of multiple beam elements arranged to extend parallel to one another with a specified spacing. A filler strip, characterized by a U-shaped configuration, is inserted between adjacent beam elements. The design of the filler strip includes a crease that forms a catch surface, engaging an external shoulder on the edge of each beam element. This innovative mounting method ensures consistency regardless of the height of the element relative to the beam faces.
