CROSS-REFERENCE TO FOREIGN PRIORITY APPLICATION

Priority is claimed under 35 U.S.C. §119 to Canadian Application No. 2,593,600 entitled “Multi-Purpose Panels with a Modular Edge,” filed on Jul. 13, 2007, by Richard Kulhawe and Anthony G. Warren.

BACKGROUND OF THE INVENTION

1. Field of the Invention
The present invention relates to multi-purpose panels for constructing a continuous surface and, in particular, panels comprising of wafers having at least one modular edge.
2. Description of the Related Art
Access into wilderness areas for the purposes of natural resource discovery and exploitation requires that heavy equipment traverse areas having sensitive soil types that are easily compressed or damaged by the presence of workers, machinery and vehicles. Some representative examples of such areas are desert, muskeg, tundra, and farmland.
The fact that such environments are sensitive to the damage by compression or erosion caused by workers, machinery and vehicles has a two-fold impact. First, ongoing damage to such an environmentally sensitive area may prevent the movement of workers, machinery or vehicles over the surface of the area and cause the area to be inaccessible. Second, the damaged caused by workers, machinery and vehicles may take a decade or more to repair and thus lead to long-term environmental damage to the area.
In order to allow access to environmentally sensitive areas and to prevent environmental damage, it is known to lay temporary work surfaces, roads and landing surfaces over environmentally sensitive areas. These surfaces are designed to provide surface protection to the area and distribute the load of the weight of the objects over as wide an area as possible. Generally, more recent versions of the surface are made up of a system of interconnecting wafers that may be joined together at the edges of their sides.
The panels are designed to be as stiff as possible to distribute any load over the total surface area of the wafer and lightweight in order to allow easy transportation and placement and recovery of the panels that create the surface.
The joint system used to attach each panel together to form the surface is designed to be as strong and rigid as possible to ensure that the panels stay joined together and do not move relative to one another. Further, the joints are rigid, in order to transmit load from one panel onto adjacent panels; further reducing the damage that the load of heavy equipment may have on the environmentally sensitive area.
The first of such systems consisted of roadways made of planks, boards or logs laid out in various configurations and often nailed, bolted or lashed together. These roadways used heavy materials that were difficult to handle, put into place and joint together. As the materials were hard to use these roadways could not be recovered and became permanent structures that were difficult to repair and maintain, and as such were abandoned over time, thus preventing the natural recovery of the environmentally sensitive area.
A second version of a surface system comprises a system of interlocking wood planks that are fastened together to form a mat. U.S. Pat. No. 4,600,336 issued in the name of Waller, Jr. and U.S. Pat. No. 4,462,712 issued in the name of Penland, Sr. disclose wooden mats that are arrangements of layers of closely spaced wooden planks, the planks of each layer orientated substantially parallel to the orientation of the wooden planks of the layer above and below it. These prior art systems require the arrangement and assembly of individual boards and are labour intensive to assemble and disassemble. The joint system in these systems are an arrangement of boards in a staggered pattern in so that alternating boards extend onto an adjacent panels. As such, the joints between the boards do not provide sufficient structure to provide a rigid joint to transfer load between each of the mats. Further, as the joints are of a fixed configuration, changing the shape or profile of each joint on each mat is not possible.
U.S. Pat. No. 4,875,800 issued in the name of Hicks and U.S. Pat. No. 4,973,193 issued in the name of Watson disclose wooden mat systems using intermeshing wooden mats having over lapping edges. As with the previous mat systems, the joints are of a fixed configuration that does not provide sufficient structure to provide a rigid joint to transfer load between each of the wafers.
Current panels by a variety of methods including molding, pultrusion, assembly of component parts such as the upper wafer skin, core and lower wafer skin amongst others. With current panel systems, the edge of the panel is an integral part of the panel that is unable to be removed, as it is formed during the creation of the panel.
U.S. Pat. No. 4,629,358 issued in the name of Springston, U.S. Pat. No. 6,685,388 issued in the name of Webster, and U.S. Pat. No. 6,695,527 issued in the name of Scaux, all disclose a system consisting of two offset overlapping wafers to form a panel. The wafers are offset to expose upper and lower lips that facilitate adjacent panels to be joined together by overlapping edges using bolts, screws, nails, glue or other connecting means. As such, theses prior art systems have panels that fit together in a pre-determined and specific orientation, and do not allow modification to the edges of the panels to facilitate different types of connections or edge profiles.
United States Patent Application Publication No. 2006/0010830 in the name of Warren et al., discloses a wafer system having an integral wedge shaped edge that forms a scarf joint that allows adjacent panels to interlock together using bolts, screws, nails, glue or other connecting means. As with the other prior art systems, the edge once formed for each panel cannot be changed and cannot be modified after the fabrication of the panel.
It is, therefore, desirable to provide a panel system that overcomes the limitations of the prior art.

BRIEF SUMMARY OF THE INVENTION

An apparatus to construct a continuous surface is provided. In one embodiment, a panel is provided having a wafer and a modular joint system that is designed to have a stiffness and weight to satisfy the requirements for a variety of surfaces such as oil rig sites, helicopter pads, temporary roads, housing sites amongst other applications. Each wafer can have at least three sides. An edge having the same or a different profile is attached to one of the sides of the wafer to allow each wafer to be attached to an adjacent wafer. The modular design of the joint system allows for the manufacturer to use and modify existing wafers with different edges to produce a panel that meets the needs of the end user without compromising the strength or rigidity of the joint to facilitate the transfer of load from one panel onto adjacent panels.
In one embodiment, the wafer and the edge can be changed with little modification to either piece to continually allow for the development of wafers and edges that better fulfill the requirements of industry and the environment or to reuse either the edge or the wafer.
In another embodiment, the wafer can have a modular design that allows it to be constructed to allow the edges to be interchanged and to allow the selection of different edges on each side of the wafer. As such, a surface can be made using a variety of panels having a variety of edge designs in order to address differences in the requirements of the panel depending on variations on ground conditions or use.
In another embodiment, the wafer and the edge can have a modular design that allows for the mass production of panel components using highly automated manufacturing techniques, driving the cost of production down and increasing the quality and reliability of the end product.
In yet another embodiment, allows for the integration of the best possible edge design for any given application and to provide the correct joint system that is appropriate for a given task and demands of the market place.
In yet another embodiment, the wafer can have a modular design that allows for the integration of the best possible edge design for any given application. There are a wide variety of needs any mat system is required to fulfill, but making the edge and the wafer into separate components that can be interchanged with one another allows the current invention to meet the changing needs of the market place.
While the apparatus can be described in conjunction with illustrated embodiments, it will be understood that it is not intended to limit the apparatus to such embodiments. On the contrary, it is intended that all alternatives, modifications and equivalents as may be included within the spirit and scope of the invention as defined by the present patent specification as a whole. For example, it is contemplated that the apparatus can encompass a variety of different edge profiles designed to achieve a specific purpose desired by the end user. As by way of example and without limitation, some edges may be designed to interlock together, to provide a smooth transition from the surface of the ground to the surface of the mat, to contain spills on the surface of the mat or to act as a barrier to prevent objects from collecting on the top surface of the mat. It is also contemplated that different configurations and connections can be utilized to attach the edge to the mat. Both permanent and detachable means can be used so long as the edge is fastened to the wafer in the manner that would allow the edge and the wafer to remain securely fastened. Further, it will be understood that all dimensions and sizes described herein, both relative and absolute, may be varied within a broad range in order to meet the needs of the end-user. As well, materials described herein are merely intended to be illustrative and are subject to a range of alternatives.

DETAILED DESCRIPTION OF THE INVENTION

In the following description, similar features in the drawings have been given identical reference numerals where appropriate. All dimensions described herein are intended solely to illustrate an embodiment. These dimensions are not intended to limit the scope of the wafer described herein, which can depart from these dimensions.
An embodiment is illustrated and described in context of providing a modular edge system for temporary surface used to distribute the load of workers, equipment and vehicles over a large surface area. However, it is contemplated that the modular edge system may be applied to any surface panel or wafer such as wall panels, ceiling panels, roofing, flooring, walkways or the like.
Referring to FIG. 1 and FIG. 2, there is illustrated a panel 100 according to one embodiment of the present invention having, a wafer 1, an upper wafer skin 5 and an opposing bottom wafer skin 15. Referring to FIG. 3 and FIG. 4, the wafer has at least three sides 10 with at least one of the sides adapted to accept an edge 20. In the embodiments shown in FIG. 3 and FIG. 4, a four-sided wafer is shown to have two opposing edges adapted to accept an edge 20. However it is contemplated that a wafer 1 may have three or more sides and that a single side, two or more sides of the wafer 1 being spaced apart or adjacent to each other, or all sides could be adapted to accept an edge 20.
Wafer skin 5 materials can include virtually any material that has the desired material properties of strength, toughness, weight, durability and others as may be required by the application and the designer. Provided that such materials can be adhered to the core so as to provide the desired properties, in such a fashion that is both structurally sound and economically viable.
In some instances, core or skin materials may require that a variety of surface treatment technologies known in the art be applied. These include, but are not limited to; mechanical abrading, chemical abrading, chemical etching, application of bonding agents, coupling agents, or sizes of a variety of chemical structures; other surface modification such as flame treating, corona treatment, plasma treatment, exposure to UV radiation, and exposure to chemical gases and liquids such as fluorine, chlorine, chromic acid, and others known in the art. The object is to create a surface that will facilitate the adhesion of the core to the skin to ensure that the skin remains intact and in place.
There are a large number of techniques known to those practiced in the art of attaching the skin materials to the core materials. These include but are not limited to; welding of like materials; hand lay-up of fiber-reinforced liquid thermoset resins onto the core surface; hand lay-up of fiber-reinforced thermoplastic resins onto the core and the subsequent addition of heat sufficient to cause the thermoplastic resin to flow and cure to the core, application of a vacuum bag to provide clamping forces to such lay-ups; resin transfer moulding; vacuum assisted resin transfer moulding; resin infusion moulding; vacuum assisted resin infusion moulding; vacuum resin transfer moulding, compression moulding, pultrusion, extrusion, and plate compression.
Wafer core materials can range from a long-list of materials. These include but are not limited to; wood, end-grain balsa wood; foams made of polyurethane, polyethylene, epoxy, polymethacrylimide, and phenolic resins; foams of the materials listed previously with various fillers such as hollow glass spheres or hollow ceramic spheres; honeycomb core materials made of aluminium, steel, stainless steel, titanium, or other metals; honeycomb core materials made of; paper either resin coated or not, produced from but not limited to, fiberglass, Nomex®, Kevlar®, wood-pulp, carbon, graphite; or other materials including but not limited to; extruded or welded polypropylene, polycarbonate, polyethylene, polyurethane, polyester, or other thermoplastics; and pultruded, extruded, or welded I-beams interlaced with any or all of the above mentioned materials that are strong enough to provide support the objects that are to be placed on the surface of the wafer.
Wafers 1 and edges 20 can be impermeable, or semi-impermeable to restrict or prevent liquids or gasses from seeping into or through the wafer. This reduces and may eliminate the “pumping” action” associated with prior art panel systems that cause environmental damage and facilitate the recovery of the panels for reuse by preventing the panels from being embedded in the ground on which the panel system is placed. The “pumping action” occurs when the panels or joints between the panels flex under the load moving over the surface of the panel system. As the panels and joints flex, water and debris accumulate onto the panels, by flowing over the sides of the panel, through the panel itself, if it is not made of a water proof and/or mud proof material, or through the joints between the panels of the panel system. As the action is repeated, the panel sinks further into the ground making the recovery of the panels difficult.
Referring to FIG. 5, FIG. 6A, FIG. 6B, FIG. 7A, FIG. 7B, FIG. 7C and FIG. 7D, there is illustrated an edge 20 according to one embodiment of the wafer 1 having an upper edge skin 25, a joint end 30 and an opposing connector end 35. The upper edge skin 25 may consist of the same types of material as the upper 5 and the lower wafer skins 15 of the wafer 1. The edge 20 may also have a lower edge skin 45 as illustrated in the example embodiments of FIG. 6 and FIG. 7.
Additional processes could be used to attach a variety of lifting rings and other lifting devices and well as the application of a variety of coating materials to protect the wafer and edge from damage caused by the environment and end-users. For example, hand grabs and lifting rings may be found on either side of the wafer 1 or edge 20 to allow better handling of the wafer 1.
The modular design also allows for the integration of the best possible edge design for any given application. By way of example, complementary interlocking edges may be attached to adjacent panels to ensure that the panels remain secured, and to provide a means to create a continuous surface.
An edge 20 of the wafer 1 can be made of any material that meets these requirements. These materials include but are not limited to; fiberglass reinforced plastic utilising both thermo-set and thermoplastic resin formulations; carbon-fiber reinforced plastics utilising both thermo-set and thermoplastic resin formulation; other fiber reinforcements utilizing both thermo-set and thermoplastic resin formulations; other engineered plastics, aluminum, steel, and other metals; wood, ceramic, and any other material that can be formed into the shape of the required edge.
Manufacturing techniques known to those practiced in the art that may produce the edge 20 and the wafer 1 include, but are not limited to, compression moulding, extrusion, pultrusion, injection moulding, blow-moulding, rotational moulding, machining, shaping, routing, welding, bending and forming or any other technique that is suitable for the shaping of the material that makes up the edge 20 and/or wafer 1. These same techniques can be used to shape the sides of the wafer 10, the connecting end 35 of an edge 20 and the joint end 30 of an edge 20. The length of the edge 20 may also vary based on the requirements of the shape of the profile or the application in which the temporary or permanent surface may be placed.
The edge 20 may also be reinforced to protect the edge from damage or to protect the edge from unnecessarily compressing. The edge 20 may be reinforced with a variety of materials which includes, but are not limited to, fiber reinforced materials, such as pultruded fiberglass; polymetic rods, such as rods made of various plastics, wood, steel, aluminum and other materials suited to protect the edge from damage and compression. The reinforcing materials may be integrated throughout the edge 20, placed at either the connecting end 35 or the joint end 30, or provide an inner or outer protective shell to the edge 20.
Referring to FIGS. 7A-7D, there is illustrated a joint end 30 according to one embodiment of the present invention that is adapted to fit a complimentary joint end 31 of an adjacent wafer 2. The profile and shape of a joint end 30 is dimensioned to be complementary to the profile and shape of the joint end 31 of an adjacent wafer 2 so that the joint ends 30 and 31, form a joint system with sufficient strength and rigidity to hold the adjacent wafers 1 and 2 together and to transfer load from one wafer onto the adjacent wafer.
A joint end 30 can be a wide variety of shapes and designs to meet the requirements of various applications. As illustrated in the embodiments set out in FIGS. 7, 9 and 12, a joint end 30 of an edge 20 of a panel 1 may be profiled to fit in mated or interlocking attachment with the profile of a complementary joint end 31 of the edge 20 of an adjacent wafer 2. It is known by a person skilled in the art of panel construction and use that other edge profiles would allow the joining of adjacent wafers 1 and 2.
Known profiles for joint ends 30 for an edge 20 are illustrated in FIGS. 7A-7D in which the profile of the joint end 30 of an edge 20 is a lip or tab that is dimensioned to overlap with the lip of a complementary joint end 31 of an edge 20 of an adjacent wafer 2. As shown in FIG. 7A, the profile and shape of joint ends 30, 31 can be a lap joint. As shown in FIG. 7B, the profile and shape of joint ends 30, 31 can be a tapered lap joint. As shown in FIG. 7C, the profile and shape of joint ends 30, 31 can be an S-shaped lap joint. As shown in FIG. 7D, the profile and shape of joint ends 30, 31 can be a modified lap joint for use with at least one fastener, such as a bolt and nut or any other suitable fastener as well known to those skilled in the art. The profile of complementary edges need not be mirror images of each other; they need only to fit together to form a sufficiently rigid joint with or without an attachment means 36, so that load is transferred from one wafer to the adjacent wafer to which it is attached. Suitable attachment means of complementary joint ends 30 and 31 may be achieved by any number of joint attachment means known in the art, which includes but is not limited to frictional fit, nails, screws, bolts and nuts, mortises and tenons, rivets, welding, soldering, glue, hook and loop fasteners (such as Velcro™), or any other means that provides a secure attachment that allows the complementary joint ends 30 and 31 to transfer load from one panel to its adjacent panel. It is also contemplated that a number of joint attachment means may be used alone or in combination with other attachment means to attach complementary joint ends 30 and 31. Further, the attachment may be permanent or transient to allow the creation of a permanent or a temporary surface that may be disassembled.
Referring to FIG. 5, FIG. 6A and FIG. 6B, there are illustrated embodiments having a connector end 35 of an edge 20 of an embodiment of the present invention that is adapted to fit in mated attachment with the side of a wafer 10 as illustrated in FIG. 9. The connector end 35 is dimensioned so that it may be meet the edge 20 in mated or interlocking attachment. The attachment of the edge 20 via its joint edge 35 to the side of the wafer 10 may be achieved by any number of edge attachment means known in the art, which includes but is not limited to frictional fit, nails, screws, bolts and nuts, mortises and tenons, rivets, welding, soldering, glue, hook and loop fasteners (for example, Velcro™ fasteners), or any other means that provides a secure attachment that allows the edge 20 to remain attached to the connector end 35 of the side of the wafer 10. It is also contemplated that a number of edge attachment means may be used alone or in combination with other attachment means to attach a given edge 20 to a given side of a wafer 10. Further, the attachment may be permanent or transient to allow the modification of a given side of a wafer 10 with a different edge 20.
Referring to FIG. 8A, an edge close out 50 a may be applied to an edge of a wafer (10) to allow the attachment of an edge 20 to the wafer 1. Alternatively, an edge close out 50 b (as shown in FIG. 8B) or 50 c (as shown in FIG. 8C) may be applied to cover or protect an edge of the wafer 10. The edge close out can take a large variety of shapes and sizes and can be made from a similar list of materials as the upper and lower wafer skins 5 and 15 and the edge 20 so long as the edge close out 50 a will allow the necessary amount of strength to maintain the integrity of the wafer 1 to be maintained where the wafer 1 and edge 20 are connected or where the wafer 1 is covered by the edge close out 50 b and 50 c.
Referring to FIG. 10, FIG. 11 and FIG. 12, there are illustrated embodiments of the present invention providing examples of confirmations of edge attachment to a wafer having at least three sides. Referring to FIG. 10, there is an embodiment illustrating, modular edges 20 attached to adjacent sides of a wafer 1. Referring to FIG. 11, there is an embodiment illustrating modular edges 20 attached to all sides of a wafer 1. Referring to FIG. 12, there is an embodiment illustrating attachment of modular edges 20 to adjacent sides of a wafer 1 and to the opposite side of the wafer 1.
The wafer may be made with a continuous wafer skin, and all spaces between the edges and the wafers and between edges of adjacent wafers may be sealed using a number of methods and techniques known in the art that prevent the accumulation of water, dirt, mud, ice or other debris in the spaces. Examples of suitable techniques known in the art are, but not limited to welding, soldering, coating, taping, or caulking.
The dimensions of the wafers of the present invention can easily be varied with changes in production tooling. In one embodiment, the wafers with edges may be approximately 1″ to 100″ in width, 1″ to 500″ in length and 1/16″ to 6″ in thickness. The width and length of the wafer may vary so that the wafers may be easily loaded and transported by standard vehicles and containers. The thickness of the wafer and the edge may also vary depending on the application, and the material used to construct the wafer. The shapes and sizes of the wafers can vary in order to meet the requirements of an application. For example, wafers of different shapes can be assembled to form curves, slopes and other shapes required to avoid obstacles in the environment.
The embodiments illustrated in FIGS. 1-14 would allow the fabrication of wafers 1 separate from edges 20 to allow the mass production of wafers 1 that are able to connect to different edges 20 with different joint ends 30. This allows for lower production costs and less time wasted in adjusting the manufacture machinery to produce a panel with a specific profile to the joint end 30.
Further, the embodiments illustrated in FIGS. 1-14 allow the user to select an appropriate joint end 30 for a wafer 1 to match up with the joint end 31 of the adjacent wafer 2. As such, the user does not have to account for the orientation of the fixed edges present in the prior art panel systems, to ensure that all the panels are correctly position so that the appropriate joint end will meet up with the complementary joint end of the adjacent panel. The embodiments illustrated in FIGS. 1-14 would allow the user to start building a continuous surface made up of the panels 100 from multiple positions without consideration of the orientation of the panel, as the user is able to select an edge 20 for a wafer 1, the edge 20 having a complementary joint end 30 to the joint end 31 of the adjacent wafer 20.
Referring to FIG. 9, an embodiment of wafer 1 is illustrated that provides a panel system forming a flat linear surface of panels with parallel sides connected end-to-end to form a straight roadway. However, as illustrated in FIG. 14, the curved surfaces can be assembled by changing the shape of the panel to a trapezoidal or substantially wedge shaped panel by varying the length of opposing sides of the wafer 10 a and 10 b. As further illustrated in FIG. 14, a number of panels of different shapes and dimensions can be connected together to form a continuous curved surface, so that the user may form the continuous surface of panels to avoid objects in the user's path.
Referring to FIG. 13, an embodiment is illustrated that provides for an array of panels stretching in two dimensions. The array of panels may be placed in off-set rows in which each panel is joined to at least two adjacent panels on at least one side of the panel. In another embodiment, a panel may be connected to two adjacent panels along at least two adjacent edges.
Further, the panel system may be used as a continuous surface supported by scaffolding, frame or the like to provide structures such as roofing, bridge decking, walkways, catwalks, docks, gang planks, flooring for buildings and the like.
Although the present invention has been described by way of a detailed description in which various embodiments and aspects of the invention have been described, it will be seen by one skilled in the art that the full scope of this invention is not limited to the examples presented herein.
