ANGULAR SET-IN INSERT BINDER BAR FOR FLOOR COVERINGS Filed April 14, 1960 INVENTOR. E DWARD GRUNWA LD United States Patent flice Patented Oct. 10, 1961 3,003,185 ANGULAR SET-1N INSERT BINDER BAR FOR FLOOR COVERINGS Edward Grunwald, 134 W. 58th St., New York, N.Y.
Filed Apr. 14, 1960, Ser. No. 22,312 1 Claim. (CI. 16-16) This invention relates generally to protectors for floor coverings and more particularly to a binder bar for binding adjacent strips of floor covering.
A principal object of the present invention is to provide an elongated rectangular binder bar having an angular portion along one long edge thereof.
Another object of the invention is to provide an elongated rectangular binder bar having an angular portion forming one long edge thereof, the free long side edge of the angular portion being formed with a curved periphery, the periphery being formed with a square-cornered groove to receive the adjacent long edge of a strip of floor covering insert.
A further object of the invention is to provide a binder bar of this character that is simple and rugged in construction and that can be manufactured and sold at a reasonable cost.
For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings, and to the appended claim in which the various novel features of the invention are more particularly set forth.
In the accompanying drawings forming a material. part of this disclosure:
FIG. 1 is a fragmentary top perspective view of a binder bar embodying my invention.
FIG. 2 is a sectional view through a strip of floor covering in flatwise condition.
FIG. 3 is a sectional view showing the binder bar applied over a joint between different kinds of floor covenng.
FIG. 4 is a view substantially similar to FIG. 3 showing a diiferent application of the binder bar, and a modified form of binder bar.
FIG. 5 is a view similar to FIG. 4 but showing still another different application of the binder bar.
FIG. 6 is a perspective view of a fragment of the binder bar of FIG. 4.
FIG. 7 is a view similar to FIG. 1 showing another modification of the invention.
Referring in detail to the drawings, in FIG. 1 a fragment of a binder bar embodying the invention is shown and designated generally by the reference numeral 10. The binder bar consists of an elongated one-piece rectangular body or strip -12 of rolled, cast or extruded metal, such as chromium, aluminum, yellow or white brass or like material adapted to bind a flexible strip of carpet or the like to a supporting surface. The body is substantially flat with its top side 14 and bottom side 16 flat throughout its length and width.
An upstanding flange 18 is formed along one long edge of the body, the flange being bent over at its outer end and rounded as indicated at (20 and having a flat under face 21. The body 12, flange 18 and rounded end 20 define a channel-shaped groove 22.
In accordance with the invention, the body of the bar is bent for the length of the bar at an angle to the horizontal, forming a tapering long end edge 24, tapering downwardly and outwardly. The extreme free end of the bent portion terminates in an enlargement 26 for the length of the body, the enlargement being substantially twice the width of the flange 18. The enlargement is bent inwardly at its outer end and rounded as indicated at 28, the bent over portion being formed with a flat under face 30. The slanting portion 24, enlargement 26 and bent over portion 28 define a channel-shaped groove 32.
A series of spaced countersunk holes 34 are formed centrally of the body portion ofthe bar for receiving fastening elements, such as screws 36, one being shown in FIG. 3.
A strip 38 of facing material such as linoleum having square-cornered end edges 40 is removably inserted in the channel 42 defined by the top surface of the body, the flange 18 and the enlargement 26. The linoleum is held in place by the flat faces 21 and 30 of the flange 18 and enlargement 26, respectively, for finishing 011 the binder bar. The linoleum strip 38 is notched as indicated at 44 for its entire length on its underside adjacent one long edge as shown in FIG. 2 to facilitate bending of the strip to conform to the shape of the binder bar.
In FIG. 3, a portion of a wooden floor 46 is shown covered with a strip of carpet 48 and a block of tile 50. A cushioned lining or pad 52 may be placed under the strip of carpet. The tile 50 is supported by a strip of plywood 54.
The binder bar 10 is shown binding the carpet and tile together. The bar is shown with its bent portion 24 disposed along and over the long edge of the tile 50, with its enlargement in clamping engagement with the tile, the remainder of the bar being clamped flatwise upon the down-pressed pile 56 of the carpet 48. The bar is fastened to the floor 46 by the screws 36, only one screw being shown, passing through the holes 34 in the bar 10 and through the carpet into the floor. The pressure of the bar tends to squeeze the pile structure of the carpet, and the pressure of the enlargement 26 on the tile clamps the tile against the floor.
In FIG. 4, the modified form of binder bar 10 is shown fastening one long edge of the carpet strip 48 to the floor 46, the slanting portion 24 of the bar seating directly upon the top surface of the floor. In this form of binder bar a wedge-shaped lug 13 extends upwardly across the bar at the juncture of the slanting portion. Lug 13 seats in the notch 44 in the linoleum 38 and prevents displacement thereof.
In FIG. 5, the binder bar '10 is disposed against a block of tile 60. Block 60 is supported by a strip of plywood 64. The strip of plywood 64 extends beyond the edge of the block 60 and supports the body portion 12 of the binder bar so that the top surface of the linoleum insert 38 on the binder bar is flush with the top surface of the tile block 60. The binder bar is fastened to the floor by means of the screws 36 extending through the strip of plywood into the floor. The flange 18 of the binder bar is pressed flat-wise against the adjacent flat edge of the block 60, and the curved periphery of the enlargement 26 impinges against the surface of the floor 46.
The modified form of binder bar 10 shown in FIG. 7 differs merely in the construction of the long end edges of the body 12'. In this form, one end edge, the lefthand end edge, is formed with an upstanding rail 18 therealong, and the right-hand edge is formed with a similar upstanding rail 26- therealong. Rail 18' is formed with a dovetail groove 70 in the center of its top surface and extending from end to end of the rail. The rail 26' is formed with a similar groove 72 extending therealong. A rail 74 having a curved top 76 and a depending flange 78 similar in cross section to the cross section of groove 70 is slidably mounted in the groove 70 and serves as a trimming for the binder bar. A similar rail 80 with a curved top surface 82 and dovetail flange 84 is slidably mounted in the groove 72 and serves as a trimming for the bar. The linoleum strip inlay 38 is clamped in position by the inner long edges of the rails 74 and 80.
While I have illustrated and described the preferred embodiments of my invention, it is to be understood that Ido not limit myself to the precise constructions herein disclosed and that various changes and modifications may be made within the scope of the invention as defined in the appended claim;
Having thus described my invention, What I claim as new, anddesire to secure by Letters Patent is:
A binder bar adapted to overlie a joint between adjacent strips of floor covering, said binder bar comprising a flat rnetal body of elongated rectangular shape, said body being bent at an angle to the plane of the body adjacent to and along one long side, an enlargement along the upper surface of the free end edge of said ben't portion, said enlargement having a" curved outer periphery, said enlargement having a central dovetail groove on its upper surface for its entirelength, a rail having a curved top surface and a dovetail-shaped flange slidable in said groove, an enlargement along the upper surface of the free end edge of the other side of the body, said enlargement having a central dovetail groove on its upper surface for itsentire length, a rail having a curved top surface anda dovetail-shaped flange slidable in said latter groove, theinner long edges of the rails serving to clamp a strip'of fioor' covering onto the body of the bar.
