  Constructive arrangement in floor finishing elementUSPTO Application #: 20080060304Title: Constructive arrangement in floor finishing element Abstract: Floor panels are secured to a sub-floor by elongated elements, one of which is secured to the floor itself and has an inverted T-shape, the other of which elements defines downwardly open socket means for receiving an arrow shaped projection on the stem portion of that T-shaped support element. A precise fit is afforded between these elements 1 and 2 so that the floor panels are locked in place by engagement between the arrow shaped projection in the support element and the socket portion of the upper retaining element. An alternative version of the disclosure shows a more secure connection between these elements. (end of abstract)

CROSS REFERENCE TO RELATED APPLICATIONS [0001]This application is a continuation-in-part of currently pending U.S. application Ser. No. 11/520,366 filed Sep. 13, 2006, the disclosure of which is incorporated by reference herein. The following three design patent applications are also incorporated by reference herein, and priority to the following U.S. Design applications is also made: U.S. Ser. No. 29/279,789, entitled FLOORING SUPPORT STRIP, filed May 8, 2007; U.S. Ser. No. 29/279,790, entitled FLOOR STEP, filed May 8, 2007; and U.S. Ser. No. 29/279,791 entitled FLOOR/WALL FINISH MOLDING filed May 8, 2007. FIELD OF THE INVENTION [0002]This invention deals generally with extruded polymeric or metal floor support elements to anchor floor panels to an existing sub-floor or structure. BACKGROUND OF THE INVENTION [0003]The use of laminated floors of wood in residential and commercial buildings is well known. Such laminated floors are generally provided in segments or panels that are generally mounted parallel to one another above a sub-floor. [0004]Present technology provides for the anchoring of these floor panels by nails or by the use of adhesive, which leads to some problems when the floor panels are laminated with a top layer of polymeric materials, such as Formica or its melamine equivalent. The marginal edges of such panels tend to splinter absent the use of an edging or other treatment for the marginal edges of the panel. SUMMARY OF THE INVENTION [0005]In accordance with the present invention a support structure comprises a plurality of elongated floor panels, support elements having a cross sectional shape of inverted T-shape, with upwardly facing lands for supporting the marginal edges of adjacent panels. The panels are spaced apart so that the T-shaped central stem portion projects upwardly between the spaced panels. An arrow shaped upper portion of the stem is more particularly defined by depending divergent legs that terminate above these lands. [0006]A plurality of elongated panel retaining elements, each having a downwardly facing land for abutting a top surface of at least one of the panels is provided for mating with these support elements. Each panel retaining elements has a downwardly open elongated socket for receiving, and retaining, the arrow shaped upper stem portion of the support element. The socket is more particularly defined by depending ribs which are resiliently derformable projections that include barbed lower end portions for anchoring the retaining elements to the underlining support elements. [0007]In another version of the invention the retaining element has one side for engaging one marginal edge of a panel, and the opposite side defines an inclined ramp for use at a doorway or entryway, that leads to an area fitted with floor panels in accordance with the present invention. Thus, a transition is created between the slightly raised new floor afforded by these panels, and the original sub-floor or other existing floor area adjacent to the floor panels and support/retaining elements of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS [0008]FIG. 1 shows in perspective a support structure in accordance with the present invention. [0009]FIG. 2 is an exploded view, also in perspective, to show the various elements of the present invention with reference to adjacent panels in a floor such as that of FIG. 1. [0010]FIG. 3 is an end view of the retaining element shown in FIG. 2. [0011]FIG. 4 is a sectional view illustrating two floor panels assembled with a support element 1 and retaining element 2, these elements being in assembled relationship in FIG. 4. [0012]FIG. 5 shows a floor panel such as that depicted in FIGS. 1, 2 and 4 together with an extruded retaining element 3 for transitioning from the existing floor Q to the paneled floor P. [0013]FIG. 6 is an exploded view of the components illustrated in assembled relationship in FIG. 5. [0014]FIG. 7 is an end view of the retaining element 3 depicted in FIGS. 5 and 6. [0015]FIG. 8 shows the retaining element 3 of FIGS. 5, 6 and 7 assembled with a panel support element 1 of the type described with reference to FIGS. 1-4 inclusively. [0016]FIG. 9 shows in an alternative flooring support strip similar to that illustrated in FIG. 6 at reference numeral 1. [0017]FIG. 10 is a perspective view showing an alternative embodiment for the floor step illustrated in FIGS. 7 and 8 above. [0018]FIG. 11 shows in perspective an alternative form for the floor/wall finish molding illustrated in FIGS. 3 and 4 above. [0019]FIG. 12 is an assembly of the components from FIG. 9 and FIG. 10.
