    Abstract: Laminated wood strip or plank flooring members are disclosed having adjacent edges of adjacent strip or plank members slightly reverse-beveled, i.e. 2.degree. to 7.degree. from vertical, to tightly fit together to provide precise, flush contact between adjacent upper surfaces of adjacent strips or planks. The strip or plank wood materials are provided in various lengths and various predetermined widths so that the random width and length strip or plank materials can be fitted together to provide a most unexpected and pleasing appearance wherein each adjacent strip or plank member is precisely fitted together and adjacent surface portions are substantially flush, or in contact.

    Abstract: A finished parquet element for attaching to a surface having a plurality of members bonded in one layer so as to be thin in relation to the element''s length and width. The element is coated with a sealant. Interconnecting means are disposed on opposite edges of the element. To increase the element''s flexibility grooves are cut along the underside of the members. The elements come equipped with fastening means disposed along the underside of the members for securing the element to the surface. In one embodiment, an elastic foundation is attached to the member''s underside to increase its shock resistance.

    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.

    Abstract: A panel can have a face surface having a length and a width. The panel can include a first tongue that extends along the length and a second tongue that extends along the width. The pane can further include first front and back legs that extend along the length of the panel and define a first groove therebetween and second front and back legs that extends along the width of the panel and define a second groove. At least one of the first tongue or the first back leg can a longitudinal dimension that is greater than the length of the face surface; or at least one of the second tongue or the second back leg can have a longitudinal dimension that is greater than the width of the face surface.
