Flexible cover for boards of a deck structure
A cover for boards of a wooden deck structure is made of flexible material and is preferably made from polyvinylchloride. The cover has a central portion with side portions that are integral therewith and can pivot relative to the central portion from a first position that is substantially parallel to the central portion to a second position that is substantially perpendicular to the central portion. The cover can be formed into rolls of significant length and can be installed by cutting an appropriate length from the roll to completely cover a single board from end to end. No adhesives or fastening means are required. A combination of a cover and wooden deck structure, and a method of installation of the cover on a deck structure is also provided. Each board of the deck is covered individually.
1. Field of the Invention
This invention relates to a cover for boards of a wooden deck structure where the cover is made of flexible material as a central portion with side portions that are integral therewith and can pivot above the central portion.
2. Description of the Prior Art
Covers for deck boards are known in which a cover installed on each board. However, previous covers suffer from one or more disadvantages. One disadvantage is that previous covers are made from rigid material that has a U-shape and a specific length. These covers are extremely expensive and they have a very high shipping cost because of their fixed shape. These rigid covers also have a specific length, which differs from the length of the deck boards onto which the covers are to be installed. Usually the deck boards are longer than the rigid covers and therefore two or more of the rigid covers must be installed on one deck board resulting in seams being located between adjacent covers. Previous deck boards often are difficult to install because they do not properly fit the deck board. Previous coverings must also be fastened to the deck board and the fastening can result in the covering becoming damaged. Also, when the covering is fastened to the deck boards, the fastening can be difficult to remove when it is desired to remove the deck board. If adhesive is used to attach the covering the deck board can be permanently damaged by removing the covering. The rigid coverings can be uncomfortable for a user to walk on, particularly when the user is barefoot. The Forshee U.S. Pat. No. 4,885,882 describes a rigid U-shaped channel member which fits over one board of a deck structure. Channel members are attached to the board by glue. The Tumball U.S. Pat. No. 4,907,387 describes a rigid channel that is attached to boards of a deck structure applying a bonding material. The Oliveri U.S. Pat. No. 5,794,390 describes a rigid covering for deck boards which are attached to the wood boards by adhesive and other fastenings means and also by screws.
The rigid U-shaped coverings cannot be made to fit over warped deck boards. Since the decking is used outside, it is subjected to high fluctuations in temperature. The wood of the deck boards expands and contracts at a different rate than the rigid covering and the different coefficients of expansion will result in damage to the covering or to the deck boards, or to the deck structure.
The rigid plastic coverings can be very time consuming to install as they often require installation of a number components. Wooden deck structures are often made from pressure treated lumber and that lumber which contains chemicals, can be harmful to humans particularly if splinters from the deck penetrate the skin.
The O'Connor U.S. Pat. No. 5,475,952 describes a floor covering material in the form of a plurality of strips having a fibrous floor covering layer bonded to a plastic layer. The covering layer is attached to the deck plank by staples that are applied through the covering layer. The covering layer has no parts that extend downwardly or covering the side surfaces of the planks.
None of the previous products has achieved even a reasonable level of commercial success. Some previous deck structures are made entirely of plastic material and are many times more expensive than wood structures of similar size.
SUMMARY OF THE INVENTIONIt is an object of the present invention to provide a deck covering which is available at a reasonable cost so that it will not add greatly to the cost of the wood structure where the deck covering will not be damaged by the expansion and contraction of the wood deck boards, which will provide a cushioned surface to a user, which will protect the user from splinters and injuries from fasteners, is made from a single material, will remain in place without the use of fasteners, will protect both the top and sides of the deck boards from the weathering, has virtually no seams, will not mildew or rot and is simply and easy to install and remove.
A cover for boards of a wooden deck structure comprises an elongated strip having two outer edges that are substantially parallel to one another. The strip is made from flexible material and has two ends with a central portion and two side portions located on either side of the central portion. The side portions are integral with the central portion and the side portions are pivotable relative to the central portion from at least a first position that is substantially parallel to the central portion, to a second position that is substantially perpendicular to the central portion.
A cover and boards of a wooden deck structure in combination, has boards that are made from wood and have a generally rectangular cross-section. The cover comprises an elongated strip having two outer edges that are substantially parallel to one another. The strip is made from flexible material and has two ends with a central portion, and two side portions located on either side of the central portion. The side portions are flexible about the central portion from a first position substantially parallel to the central portion, to a second position substantially perpendicular to the central portion. The cover is sized so that the top portion covers a top of one board, and the side portions extend downwardly on either side of the board. When the boards are adjacent to one another to form a supporting surface of the deck structure, the boards are separated by a gap of sufficient size to receive the two side portions of the strip. There is one side portion for each board in each gap between adjacent boards.
A method of installing a cover on boards of a deck comprises unrolling a sufficient length of the cover from the roll to completely cover a particular deck board from end to end of the deck board, cutting the strip of the cover to an appropriate length, installing the cover on the deck board by pivoting the side portions downward relative to the central portion, and inserting the side portions into a gap on either side of the board with the lower surface of the central portion resting on an upper surface of the board.

While fasteners or fastening means can be used with the cover of the present invention, fasteners are not required to be used unless, perhaps, very small pieces of the cover are being installed. When used to cover a deck board, when the cover is installed with the side portions inserted at each side of the deck board and the central portion on top of the deck board, the weight of the cover is usually more than sufficient to hold the cover in position on the deck board without any fasteners or fastening means. Also, the vertical side portions assist in holding the cover in position as the side portions resist forces that tend to bend or curve the central portion upward.
Since the cover is extruded in one piece, any reasonable length of cover can be extruded. For example, rolls having a length of 50, 75 or 100 feet are suitable. Preferably, rolls have a length of at least 50 feet. The cover provides a resilient cushion on the deck boards, thereby providing greater comfort to a user, as well as protection from slivers and injury. The cover also protects the deck boards. Therefore, less expensive wood can be used than would be desirable without the cover on each of the boards as the cover protects the deck boards. For example, relatively inexpensive non-pressure treated wood can be used. Alternatively, pressure treated wood or even cedar can be used and the cover will greatly extend the life of the wood.
