Method for bending a vinyl floor plank to form a stair nose plank

Abstract

A method for bending a vinyl floor plank to form a stair nose plank. A first bending gap is established between two blending blocks and a second bend gap is established between two second bending blocks. Heat is applied to a vinyl floor plank along a first bend location. The vinyl floor plank is then placed into the first bend gap. A user presses downward on the vinyl floor plank to form a first right angle bend. Heat is applied to a vinyl floor plank along a second bend location. The vinyl floor plank is then placed into the second bend gap. The user presses downward on the vinyl floor plank to form a second right angle bend. The first right angle bend and the second right angle bend combine to form a U-shaped bend to form a stair nose plank. In a preferred embodiment the stair nose plank includes a locking mechanism along its edges. In a preferred embodiment heat is applied by utilization of an acrylic bending machine.

Claims

1. A method for bending a vinyl floor plank to form a bent stair nose plank, said method comprising the steps of: A. establishing a first bend gap between two first bending blocks, B. establishing a second bend gap between two second bending blocks, C. applying heat to a vinyl floor plank along a first bend location, D. placing said vinyl floor plank into said first bend gap, E. pressing downward on said vinyl floor plank to form a first right angle bend, F. applying heat to a vinyl floor plank along a second bend location, G. placing said vinyl floor plank into said second bend gap, H. pressing downward on said vinyl floor plank to form a second right angle bend, wherein said first right angle bend and said second right angle bend combine to form a U-shaped bend to form said stair nose plank.

2. The method as in claim 1, wherein said heat is applied to said vinyl floor plank by utilization of an acrylic bending machine.

3. The method as in claim 1, wherein said two first bending blocks are rigidly attached to a table.

4. The method as in claim 1, wherein said two second bending blocks are rigidly attached to a table.

5. The method as in claim 1, wherein said stair nose plank comprises a locking mechanism along the edge of said stair nose plank.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Utilization of the Preferred Embodiments

(6) FIG. 4 shows a top view of acrylic bending machine 5 positioned on the top of table 10. First bending blocks 11 and 12 are bolted via bolts 30 to table 10 as shown. Second bending blocks 14 and 15 are likewise bolted via bolts 30 to table 10. Bending blocks 11 and 12 are separated by bending gap 20 and bending blocks 14 and 15 are separated by bending gap 22.

(7) In FIG. 5, user has placed spacer block 40 and spacer block 41 next to adjustable support arm 50. Spacer blocks 40 and 41 and support arm 50 function to properly horizontally position a flooring plank over heating gap 6. In one preferred embodiment, heating gap 6 has been adjusted so that the gap measures approximately 10 mm. Also, in one preferred embodiment the heating tube has been adjusted so that the heat applied through heating gap 6 is approximately 425° C.

(8) In FIGS. 6-8, the user has placed plank 1 against over heating gap 6 and adjacent to spacer block 41. Plank 1 is a vinyl plank having a thickness of approximately 5 mm. In a preferred embodiment, the user holds plank 1 over heating gap 6 for approximately 50 seconds.

(9) In FIG. 9, the user has placed plank 1 in bending gap 20 so that heated area 1B is located near the top of bending blocks 12 and 11.

(10) In FIGS. 10 and 11, the user has pressed down on plank 1 as shown so that first right angle bend 100 is formed in plank 1. The user holds plank 1 down in the position shown in FIGS. 10 and 11 for approximately 50 seconds while bend 100 cools to hold rigid its shape at the right angle.

(11) In FIG. 12, the user has placed bent plank 1 over heat gap 6 as shown to heat plank 1 at location 1C. In a preferred embodiment, the user holds plank 1 over heating gap 6 for approximately 50 seconds.

(12) In FIG. 13, the user has placed plank 1 in bending gap 20 so that heated area 1C is located near the top of bending blocks 15 and 14.

(13) In FIG. 14, the user has pressed down on plank 1 as shown so that second right angle bend 150 is formed, thereby forming bent plank 1D. The user holds plank 1D down in the position shown in FIG. 14 for approximately 50 seconds while bend 150 cools to hold rigid its shape at the right angle.

(14) FIG. 15 shows a perspective view of bent plank 1D having U-shaped bend 200 to form a stair nose piece. It should be noted that plank 1D includes locking mechanism 2 for easy, efficient and secure installation. For example, FIG. 16 shows multiple stair nose planks 1D installed on stairs and locked to non-bent planks 1.

(15) Although the above-preferred embodiments have been described with specificity, persons skilled in this art will recognize that many changes to the specific embodiments disclosed above could be made without departing from the spirit of the invention. Therefore, the attached claims and their legal equivalents should determine the scope of the invention.
