The present invention relates generally to backed panels. Examples of panels that may benefit from the present invention include siding panels, wall panels, and other similar, suitable, or conventional types of panels. For instance, U.S. Pat. No. 6,321,500 is incorporated by reference in its entirety as one example of a backed panel that may benefit from the present invention. This application also incorporates the following applications by reference in their entirety: U.S. Provisional Application 60/640,158, filed Dec. 29, 2004, and U.S. application Ser. No. 11/320,169, filed Dec. 28, 2005.
In order to enhance the thermal insulation of building structures, it is known to provide one or more layers or panels of insulating material between a vinyl facing panel and a building structure. The backing may also improve the structural characteristics of the facing panel. Known insulated siding systems exist in many different forms. For instance, it is known to nail large sheets of insulating material to the building structure and then install the siding over the insulating material. Another system places a panel of insulation material in a slot behind the vinyl facing panel. Yet another system pours foam filler into the back of a vinyl facing panel such that the foam filler conforms to the geometry of the vinyl facing panel.
Moisture may accumulate behind a backed panel due to a variety of reasons including condensation and rain. The accumulation of moisture behind a backed panel may eventually lead to numerous problems. For instance, prolonged exposure to moisture may cause damage to the backed panel including, but not limited to, delamination, deterioration, oil canning, and other types of moisture damage. In addition, the accumulation of moisture may lead to the growth of mold, mildew, fungi, and other types of growth on the underlying structure and the backed panel. The moisture may even cause other types of damage to the underlying structure such as rotting, deterioration, and other types of moisture damage.
One exemplary embodiment of the present invention provides a drainage pathway, which is comprised of at least one groove, for a liquid on a surface of a backing portion of a paneling unit. For example, a backing portion may include a plurality of drainage grooves that may enable a liquid to drain. Optionally, at least one connector groove may be provided that may intersect at least two drainage grooves. As a result, an exemplary embodiment of the present invention may optionally provide alternative drainage pathways in a system of connected drainage grooves and connector grooves.
Another exemplary embodiment of the present invention may optionally include at least one rib. Optionally, a rib may be adjacent to a drainage groove or between adjacent drainage grooves. A rib may assist with liquid drainage. In addition, a rib may also enable ventilation behind the backing portion. Improved ventilation may help to prevent damage to the backing portion or an overall paneling unit. In addition, improved ventilation may help to prevent damage to an underlying structure such as may be caused by moisture.
In addition to the novel features and advantages mentioned above, other features and advantages of the present invention will be readily apparent from the following descriptions of the drawings and exemplary embodiments.
In
The backing portion 20 may be glued or otherwise laminated or attached to the inside of the cover panel 30. For example, an adhesive may be used to bond a portion of a backed portion 20 to a portion of the inside of a facing panel 30.
In addition, the facing portion 30 may include an attachment strip 32 (e.g., a nailing strip), a tongue 34, and a groove 36. The facing panel 30 of the present invention has a portion 35 that rearwardly extends to attachment strip 32. The portion 35, alone or in combination with attachment strip 32, substantially covers the end or tip of the backing portion 20. More particularly, the portion 35 wraps around and abuts or is substantially adjacent to the end or tip of the backing portion 20. As a result, the portion 35 protects the end or tip of the backing portion 20 from damage, particularly during shipping and installation. In this example, the attachment strip 32 is substantially in the same plane and parallel to an adjacent portion of the rear side of the backing portion 20. A channel 37 on the bottom portion of the backing portion 20 may be adapted to interlock with, overlap, and/or extend over the nailing strip 32 of the facing panel 30 of a substantially similar siding unit 10. The nailing strip (also called a nailing hem) 32 may have a plurality of openings for receiving fasteners. Nails or any other suitable mechanical fastening means may be extended through apertures in the nailing strip 32 in order to secure the facing panel 30 to a building structure. As is shown in
The top or face portion of the siding unit 10 may have a facing panel 30, which completely covers the backing portion 20. A benefit of this feature is that the backing portion 20 is protected from breakage that may occur in shipping, handling, or installation if not substantially covered with a facing panel 30.

The paneling unit of
As may be observed in
A drainage groove 330 may have any suitable orientation that enables it to provide a drainage pathway for a liquid. Such as shown in this exemplary embodiment, drainage grooves 330 may be angled downward to provide a drainage pathway for a liquid such as water (e.g., an accumulation of water such as may be produced from condensation or rain). An angled orientation may facilitate the collection of liquid in the drainage grooves 330. In particular, as shown in
In this example, at least one connector groove 340 intersects at least one drainage groove 330 on a surface of a backing portion of a paneling unit. Other variations are possible and considered within the scope of the present invention. Generally, the relationship between at least one drainage groove 330 and at least one connector groove 340 on a surface of a backing portion is that the grooves may be hydraulically connected. In other words, as may be noted from the position of the optional connector grooves 340, the intersection of connector grooves 340 with drainage grooves 330 may provide alternate pathways for a liquid to drain. As a result, if a particular drainage groove 330 is plugged or obstructed, excess liquid may be diverted to drain through another drainage groove 330 by its transfer via an intersecting connector groove 340. In this example, a connector groove 340 may be generally horizontal. However, other suitable orientations of a connector groove 340 are possible and considered within the scope of the present invention. Alternative embodiments of the present invention allow for connector grooves to be generally oriented in any suitable direction.
In this exemplary embodiment, at least one drainage groove 430 may extend through channel 420. In particular, such drainage grooves 430 include a V-shaped groove portion 432. V-shaped groove portion 432 may facilitate drainage by providing alternate drainage pathways. In particular, a V-shaped groove portion 432 may approximately form a 60° angle in this example as shown in
Backing portion 410 may include at least one rib 450. In this example, a rib 450 may extend adjacent to a drainage groove 430 or between adjacent drainage grooves 430. More particularly, a rib 450 in this exemplary embodiment may extend substantially parallel to at least one drainage groove 430 from a top edge of backing portion 410 down to channel 420. In other words, a rib 450 may extend at an angle of approximately 60° from horizontal in this example. In other exemplary embodiments of the present invention, a rib may not be substantially parallel to a drainage groove, and a rib may extend at any other suitable angle. In addition, a rib may also extend to a bottom edge of a backing portion (e.g., through a channel), and a rib may start below a top edge of a backing portion. It should also be recognized that a rib may extend only a limited distance over a portion of a backing portion in other exemplary embodiments of the present invention. In addition, multiple ribs may be generally aligned or otherwise situated adjacent to each other in some exemplary embodiments of the present invention.
An exemplary embodiment of a rib 450 may be adapted to facilitate ventilation between backing portion 410 and an underlying structure. In addition, a rib 450 may also facilitate drainage of a liquid. By improving ventilation and/or drainage, a rib 450 may help to lessen or prevent damage to paneling unit 410 or an underlying structure, which may be caused by the accumulation of moisture. For instance, prolonged exposure to moisture may cause problems including, but not limited to, delamination, deterioration, oil canning, rotting, and other types of moisture damage. In addition, a rib 450 may help to lessen or prevent the growth of mold, mildew, fungi, or other types of moisture-related growth.
A rib 450 may have any suitable structure for facilitating ventilation between backing portion 410 and an underlying structure. In this example, a rib 450 is elevated from a primary rear surface 452 of backing portion 410 in which a drainage groove 430 may be formed. In other exemplary embodiments of the present invention, at least one rib may be elevated from a primary rear surface of a backing portion, which has no drainage grooves. Ribs 450 may be spaced about every 3.250 inches in this exemplary embodiment.
An exemplary backing portion may also include a hydrophobic material. For example, a hydrophobic material may be molded into a backing portion and/or sprayed onto a backing portion. Any other suitable method (e.g. extrusion) may also be used for including a hydrophobic material in a backing portion. A hydrophobic material may be any hydrophobic material such as but not limited to, a paraffin wax, polyethylene, fluoropolymer, or any other low surface tension material. As a result, a hydrophobic material may lower the surface tension of a backing portion. Lower surface tension may cause water to bead up and drain down a backing portion faster than if the backing material did not have the hydrophobic material.
Other variations of the exemplary embodiments of the present invention are also possible. Optionally, an exemplary embodiment of the present invention may provide for an orientation of the grooves on the surface of a backing portion such that grooves of adjacent, substantially similar paneling units may be aligned when installed to form a continuous drainage groove between adjacent units. In this manner, liquid may drain from the surfaces of the backing portions of the installed paneling units through an interconnected system of substantially continuous drainage grooves. Additionally, an exemplary embodiment of the present invention may optionally provide for at least one connector groove on a surface of a backing portion of a paneling unit to form at least a segment of a substantially continuous connector groove with an adjacent, substantially similar paneling unit when installed. As discussed above, the optional substantially continuous grooves between adjacent panels may further facilitate the drainage of liquid from the surfaces of the backing portions of installed paneling units.
One exemplary embodiment of the present invention may provide a siding unit, which is comprised of backing panel and a facing panel. Other types of paneling units comprising a facing panel and a backing panel (e.g., a wall panel unit) are considered to be within the scope of the present invention. Some advantages of a backed panel of the present invention may include improved energy efficiency, reduced air infiltration, reduced curvature in the facing panels, increased ease of installation, improved drainage, and/or improved ventilation. An exemplary embodiment of a backed paneling unit of the present invention may optionally include improved interlocking pieces and an improved backing. Chemicals may optionally be added to the backing portion that aid in the reduction or repelling of insects such as carpenter ants and termites.
The top or face portion of the paneling units may be smooth or may have any number of finishes that are known by those in the art of manufacturing paneling. The finish may add contour and texture to simulate the appearance of wooden paneling.
The paneling units of the present invention may be of various lengths, heights, and thicknesses. The particular dimensions of a panel of the present invention may be selected to suit a particular application. Some exemplary embodiments of a paneling unit of the present invention may be approximately 15 to 18 inches in height. However, as just mentioned, it should also be recognized that a paneling unit of the present invention may have any desired dimensions including a height up to or in excess of 50 inches.
The paneling units as described herein may be formed from a polymer such as a vinyl material. Other materials such as polypropylene, polyethylene, other plastics and polymers, polymer composites (such as polymer reinforced with fibers or other particles of glass, graphite, wood, flax, other cellulosic materials, or other inorganic or organic materials), metals (such as aluminum or polymer coated metal), or other similar or suitable materials may also be used. The paneling may be molded, extruded, roll-formed from a flat sheet, vacuum formed, or formed by any other suitable manufacturing technique.
Any embodiment of the present invention may include any of the optional or preferred features of the other embodiments of the present invention. The exemplary embodiments herein disclosed are not intended to be exhaustive or to unnecessarily limit the scope of the invention. The exemplary embodiments were chosen and described in order to explain the principles of the present invention so that others skilled in the art may practice the invention. Having shown and described exemplary embodiments of the present invention, those skilled in the art will realize that many variations and modifications may be made to affect the described invention. Many of those variations and modifications will provide the same result and fall within the spirit of the claimed invention. It is the intention, therefore, to limit the invention only as indicated by the scope of the claims.
