Flooring system
Abstract
Abstract A FLOORING SYSTEM UTILIZING WOOD FLOOR BOARDS, THE BOARDS BEING SUPPORTED ON TRANSVERSELY DISPOSED SPACED CHANNELS, METALLIC HOLDING CLIPS SECURING THE BOARDS IN BEARING ENGAGEMENT WITH THE CHANNELS, THE BOARDS HAVING SIDE EDGE SLOTS FOR CLIP ENGAGEMENT, THE CLIPS ENGAGING THE CHANNEL EACH HAVING A WEB PORTION VERTICALLY DISPOSED BETWEEN THE BOARDS AND HAVING, AT THE UPPER MARGIN OF THE BODY PORTION A HORIZONALLY EXTENDING PLATE PORTION WITH OPPOSING PARTS ON EACH SIDE EXTENDING INTO ONE OR MORE EDGE GROOVES, THE HORIZONTALLY EXTENDING PLATE PORTION BEING HIGHLY RESISTANT TO BENDING AND DISTORTION UNDER STRESS WITH RESPECT TO THE WEB. THE OPPOSING PARTS OF THE HORIZONTAL PLATE ARE IN FIBER PENETRATING RELATION ON OPPOSITE SIDES, SO THAT THE BENDING FORCES IN THE PLATE PORTION SUBSTANTIALLY OR TOTALLY BALANCE EACH OTHER TO LIMIT BENDING DISTORTION WHICH WOULD OTHERWISE OCCUR IN THE WEB IF THE FORCES WERE NOT SO BALANCED, THE STRENGTH BEING DETERMINED BY THE WOOD IN SHEAR WITHOUT APPRECIABLE REDUCTION IN HOLDING POWER CAUSED BY DEFORMATION OF THE CLIP ITSELF.
