Donald Rodney MacDonald FIELD OF THE INVENTION
The present invention relates to an interlocking surface covering BACKGROUND OF THE INVENTION
United States Patent 5,647,184 which issued to Davis in 1997 discloses a decking plank that has integrally formed fastening flange extending outwardly from its opposed sides.
Fastening flanges from adjacent decking planks interlock to maintain the planks in side by side relation.
The Davis reference discloses a decking plank that is suitable for use in constructing a new deck. It is not, however, a cost effective way of covering an existing wooden deck.
SZT1~IARY OF THE INVENTION
What is required is an interlocking surface covering that is suitable for use in covering an existing or a new wooden surface, or a surface made of other material to which the covering can be secured.
According to the present invention there is provided an interlocking surface covering which includes a sheet of material having a top surface, a bottom surface, a first side edge, and a second side edge. A plurality of integrally formed support ribs depend from the bottom surface. A first interlock depends from the bottom surface along the first side edge. A
second interlock is positioned on the top surface along the second side edge. The second interlock is engageable with the first interlock, such that the second interlock of one sheet of material interlocks with the first interlock of an adjacent sheet of material.
The interlocking surface covering, as described above, enables an existing or a new surface to be covered in a cost effective manner. Spaces between the support ribs serve as air flow channels that help prevent condensation build up. When properly installed, the surface covering will have water shedding capabilities that render it substantially water proof.
With the preferred form of interlock, the first interlock includes a first pair of spaced apart gripping members depending from the bottom surface along the first side edge, and the second interlock includes a second pair of spaced apart gripping members on the top surface along the second side edge.
The second pair of gripping members is engageable with the first pair of spaced apart gripping members.
Although beneficial results may be obtained through the use of the interlocking surface covering, as described above, even more beneficial results may be obtained when the first interlock is in the form of a first channel and the second interlock is in the form of a second channel. This enables fasteners that secure the sheet of material to a surface to be concealed within the second channel. It also secures the entire side edge of the sheet of material, as opposed to at selected intervals.
Although beneficial results may be obtained through the use of the interlocking surface covering, as described above, the preferred manner of interlocking the first channel and the second channel is to provide one of the first channel and the second channel with opposed outwardly extending gripping flanges and another of the first channel and the second channel with opposed inwardly extending gripping flanges.
Although beneficial results may be obtained through the use of the interlocking surface covering, as described above, when the surface covering is interlocked it is preferred that there be no ridges along the interlocking edges . Even more beneficial results may, therefore, be obtained when the second side edge has a depending "L" shaped portion with the second interlock attached in cantilever fashion.
Although beneficial results may be obtained through the use of the interlocking surface covering, as described above, when adjacent sheets of material are interlocked it is preferred that a first side edge of one sheet of material and an abutting second side edge of an adjacent sheet of material overlie a third channel. Any water penetrating between the abutting edges flows along and out of an end of said channel without wetting the surface so covered or penetrating into the second channel and wetting the fasteners isolated therein.
Although beneficial results may be obtained through the use of the interlocking surface covering, as described above, it is preferred that the ribs are tubular. The tubular ribs require less material and provide better support.
Although beneficial results may be obtained through the use of the interlocking surface covering, as described above, when the surface covering is made from some materials, such as polymer plastic, it tends to be slippery. Even more beneficial results may, therefore, be obtained when the top surface has either a raised or a recessed gripping surface.
Although beneficial results may be obtained through the use of the interlocking surface covering, as described above, if the first interlock and second interlock have movement they tend to squeak when walked on. This squeaking is eliminated or at least reduced when the sheet material is bowed. Bowing elevates the first side edge and the second side edge of the material. Then when the first side edge and second side edge are secured to the existing surface, the material becomes taught and has less tendency to squeak in the area of the interlock.
Although beneficial results may be obtained through the use of the interlocking surface covering, as described above, there is a need to stock varying lengths of the sheet material and develop a manner of end to end connection of the material.
Even more beneficial results may be obtained if end to end connection of the material can be avoided by dispensing the sheet material in rolls. The sheet material can then be cut to a desired length as it is taken from the roll.
BRIEF DESCRIPTION OF THE DRAWINGS
These and other features of the invention will become more apparent from the following description in which reference is made to the appended drawings, wherein:
FIGURE 1 is an end elevation view of an interlocking surface covering constructed in accordance with the teachings of the present invention.
FIGURE 2 is an end elevation view, in section, of the interlocking surface covering illustrated in FIGURE 1, interlocked with adjacent interlocking surface coverings.
FIGURE 3 is a detailed side elevation view of the interlocking portion of the interlocking surface covering illustrated in FIGURE 1.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
The preferred embodiment, an interlocking surface covering generally identified by reference numeral 10, will now be described with reference to FIGURES 1 through 3.
Referring to FIGURE 1, interlocking surface covering 10 comprises an elongate sheet of material 12 having a top surface 14, a bottom surface 16, a first side edge 18, and a second side edge 20. Second side edge 20 has a depending "L" shaped portion 22. "L" shaped portion has a vertical portion 23 depending from second edge 20 and a horizontal portion 25 extending from a remote end 27 of vertical portion 23 in a direction away from second end 20. When not secured in place, sheet material 12 is bowed, thereby elevating first side edge 18 and second side edge 20. A plurality of integrally formed 5 longitudinally extending tubular support ribs 24 depend from bottom surface 16. A passage 29 extends throughout a length of each of support ribs 24. Remote end 26 of support ribs 24 is on a plane parallel to a bottom surface 28 of horizontal portion 25 of "L" shaped portion 22.
Sheet of material 12 is preferably manufactured from polymer plastic. However, sheet of material 12 can be manufactured from another material, including a metal such as aluminum, without affecting the purpose or intended use of interlocking surface covering 10.
A first interlock 32 depends from bottom surface 16 along first side edge 18. First interlock 32 has a first channel 34 with a first pair of opposed inwardly extending gripping flanges 36. A second interlock 40 on top surface 14 is secured in cantilever fashion at a remote end 30 of horizontal portion of depending "L" shaped portion 22 along second side edge 20. Second interlock 40 has a second channel 42 and a third channel 43. Second channel 42 has a second pair of opposed 25 outwardly extending gripping flanges 44.
Referring to FIGURE 2, second pair of gripping flanges 44 of second interlock 40 is engageable with first pair of gripping flanges 36 of first interlock 32, such that the second interlock 40 of one sheet of material 12 interlocks with the first interlock 32 of an adjacent sheet of material 12.
Referring to FIGURE 3, second interlock 40 is secured by screws 46 through horizontal portion 25 of depending "L" shaped portion 22 at a bottom 54 of channel 42 to an existing surface 52. Referring to FIGURE 1, a "V" shaped groove 56 extends along a length of bottom 54 of channel 42. Groove 56 serves as a guide for placement of screws 46 in a straight line and perpendicularly driving screws 46 through bottom 54 of channel 42. Referring to FIGURE 3, second interlock 40 is so secured to existing surface 52 before interlocking first interlock 32 with second interlock 40. When first interlock 32 is engaged with second interlock 40, first interlock 32 is also secured to existing surface 52. When first edge 18 of one sheet of material 12 is secured to second edge 20 of adjacent sheet of material 12, second channel 42 of second interlock 40 of adjacent sheet of material 12 and heads 48 of screws 46 are covered by first channel 34 of first interlock 32. First edge 18 of one sheet of material 12 and abutting second edge 20 of an adjacent sheet of material 12 together overlie third channel 43. Any small amount of water passing between abutting first edge 18 and second edge 20 enters and flows along third channel 43, such that it is extremely difficult for any of said water to enter second channel 42. Screws 46 in second channel 42 are thus substantially isolated from exposure to water, and thereby protected from corrosion.
Referring to FIGURE 2, each sheet material 12 has a thin profile to enable a better fit between adjacent sheets of material 12. When interlocking surface covering 10 is properly installed as described above, surface 52 so covered is rendered waterproof. The majority of water falling on top surface 14 flows to an end and off of sheet material 12, and any minor amount of water penetrating between first edge 18 of one sheet of material 12 and second edge 20 of adjacent sheet of material 12 flows along and out of an end of third channel 43.
Referring to FIGURE 2, when first side edge 18 and second side edge 20 are secured to existing surface 52 as illustrated in FIGURE 3, sheet material 12 is made planar and becomes taught. When sheet material 12 is taught, it does not feel spongy underfoot and has less tendency to squeak in the area of an interlock. Referring to FIGURES 1 and 2, top surface 14 has a raised gripping surface 50.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
The preferred embodiment, an interlocking surface covering generally identified by reference numeral 10, will now be described with reference to FIGURES 1 through 3.
Referring to FIGURE 1, interlocking surface covering 10 comprises an elongate sheet of material 12 having a top surface 14, a bottom surface 16, a first side edge 18, and a second side edge 20. Second side edge 20 has a depending "L" shaped portion 22. "L" shaped portion has a vertical portion 23 depending from second edge 20 and a horizontal portion 25 extending from a remote end 27 of vertical portion 23 in a direction away from second end 20. When not secured in place, sheet material 12 is bowed, thereby elevating first side edge 18 and second side edge 20. A plurality of integrally formed 5 longitudinally extending tubular support ribs 24 depend from bottom surface 16. A passage 29 extends throughout a length of each of support ribs 24. Remote end 26 of support ribs 24 is on a plane parallel to a bottom surface 28 of horizontal portion 25 of "L" shaped portion 22.
Sheet of material 12 is preferably manufactured from polymer plastic. However, sheet of material 12 can be manufactured from another material, including a metal such as aluminum, without affecting the purpose or intended use of interlocking surface covering 10.
A first interlock 32 depends from bottom surface 16 along first side edge 18. First interlock 32 has a first channel 34 with a first pair of opposed inwardly extending gripping flanges 36. A second interlock 40 on top surface 14 is secured in cantilever fashion at a remote end 30 of horizontal portion of depending "L" shaped portion 22 along second side edge 20. Second interlock 40 has a second channel 42 and a third channel 43. Second channel 42 has a second pair of opposed 25 outwardly extending gripping flanges 44.
Referring to FIGURE 2, second pair of gripping flanges 44 of second interlock 40 is engageable with first pair of gripping flanges 36 of first interlock 32, such that the second interlock 40 of one sheet of material 12 interlocks with the first interlock 32 of an adjacent sheet of material 12.
Referring to FIGURE 3, second interlock 40 is secured by screws 46 through horizontal portion 25 of depending "L" shaped portion 22 at a bottom 54 of channel 42 to an existing surface 52. Referring to FIGURE 1, a "V" shaped groove 56 extends along a length of bottom 54 of channel 42. Groove 56 serves as a guide for placement of screws 46 in a straight line and perpendicularly driving screws 46 through bottom 54 of channel 42. Referring to FIGURE 3, second interlock 40 is so secured to existing surface 52 before interlocking first interlock 32 with second interlock 40. When first interlock 32 is engaged with second interlock 40, first interlock 32 is also secured to existing surface 52. When first edge 18 of one sheet of material 12 is secured to second edge 20 of adjacent sheet of material 12, second channel 42 of second interlock 40 of adjacent sheet of material 12 and heads 48 of screws 46 are covered by first channel 34 of first interlock 32. First edge 18 of one sheet of material 12 and abutting second edge 20 of an adjacent sheet of material 12 together overlie third channel 43. Any small amount of water passing between abutting first edge 18 and second edge 20 enters and flows along third channel 43, such that it is extremely difficult for any of said water to enter second channel 42. Screws 46 in second channel 42 are thus substantially isolated from exposure to water, and thereby protected from corrosion.
Referring to FIGURE 2, each sheet material 12 has a thin profile to enable a better fit between adjacent sheets of material 12. When interlocking surface covering 10 is properly installed as described above, surface 52 so covered is rendered waterproof. The majority of water falling on top surface 14 flows to an end and off of sheet material 12, and any minor amount of water penetrating between first edge 18 of one sheet of material 12 and second edge 20 of adjacent sheet of material 12 flows along and out of an end of third channel 43.
Referring to FIGURE 2, when first side edge 18 and second side edge 20 are secured to existing surface 52 as illustrated in FIGURE 3, sheet material 12 is made planar and becomes taught. When sheet material 12 is taught, it does not feel spongy underfoot and has less tendency to squeak in the area of an interlock. Referring to FIGURES 1 and 2, top surface 14 has a raised gripping surface 50.
Although it is preferred that support ribs 24 are tubular members, as illustrated in FIGURES 1 through 3, it will be recognized that alternative members may be used as support members, such as "I"-beams.
It will be apparent to one skilled in the art that modifications may be made to the illustrated embodiment without departing from the spirit and scope of the invention as hereinafter defined in the Claims.
