BACKGROUND OF THE INVENTION 
   1. Field of the Invention 
   This invention relates to a cargo securing system for a vehicle cargo bed and, more particularly, to an apparatus and method for securing cargo in a pickup truck bed liner cargo area with a slidable tie-down device. 
   2. Description of the Related Art 
   Vehicles that include cargo areas, such as vans and pickup trucks, have achieved great popularity. Pickup trucks typically have a cargo bed with a substantially rectangular horizontal floor frequently between four and six feet wide and six and ten feet long, and with vertical sides between one and three feet high. Typically, stationary walls form the front and two adjacent sides, and a removable or hinged tailgate forms the remaining rear side and provides access to the bed floor for cargo loading and unloading. The trucks are thus particularly suited to carry any article of most any size, even approximating the bed size. 
   A pickup truck may include a device for dividing the cargo bed. U.S. Pat. No. 5,044,682 discloses a bed liner divider system that divides a pickup truck cargo area into multiple sections. The system includes a pair of slotted brackets that attach to the pickup truck bed side walls using conventional fastening techniques. The brackets are mounted on the side walls, so that the slots are aligned vertically. A divider wall is inserted into the slots to form the separate sections of the pickup truck cargo area. 
   Vans may also include devices for dividing the cargo area. U.S. Pat. No. 5,167,479 discloses a van cargo area divider that includes a beam member and a pair of track members. The track members are slider mechanisms that insert into channels that form a pair of integral tracks within the van cargo area floor. Each slider mechanism attaches to an end cap positioned at opposite ends of the beam member. The beam member divides the cargo area into multiple sections. 
   Pickup truck bed floors are typically smooth and flat, so that any carried article(s) smaller than the cargo bed itself can slide about on the bed floor under the dynamic forces created when the truck is being driven. The cargo bed will typically include a bed liner that has one or more surfaces with a higher coefficient of friction. 
   U.S. Pat. No. 6,237,980 discloses a plastic vehicle bed liner for use in a cargo bed. The bed liner includes a relatively rigid body having a bottom wall member for frictionally engaging the vehicle cargo bed. A pair of side wall members and a front wall member project upwardly from the bottom wall member. Each wall member includes a wear inhibiting area covering at least a portion of the wall member outer surface for engaging a corresponding member of the vehicle cargo bed. 
   U.S. Pat. No. Des. 302,143 discloses an ornamental design for a vehicle cargo space bed liner. The bed liner includes a plurality of shallow walls lengthwise along the base of the bed liner. 
   U.S. Patent Application Publication No. 2002/0149223 discloses a knock-down, multi-component bed liner. The bed liner includes five sections, a front panel assembly, a left side assembly, a right side assembly, a center bottom panel, and a tailgate panel. The left side assembly and the right side assembly attach to the bottom panel to form the bed liner floor. The assemblies are attached to one another by strips or flanges that receive conventional fasteners that are inserted into a plurality of spaced-apart openings or apertures. 
   While plastic bed liners for the cargo bed typically provide greater friction against the carried article(s), the bed liners do not always prevent a carried article(s) from sliding around in the bed. A sliding article could fall from the truck, or could smash against the cargo bed sides to cause damage to the truck or itself and/or create instability in the driving characteristics of the truck. Thus, it is desirable and common when easily possible to secure the carried article(s) relative to the bed. 
   One common way of securing these carried article(s) relative to the cargo bed includes the use of a cargo securing system. U.S. Pat. No. 5,509,764 discloses a metal cargo securing system having a crossbar member attached to a beam member. The beam member includes ends that are adapted to slide within a pair of U-shaped channel tracks that are mounted on the bed walls of the pickup truck bed. 
   Cargo securing systems may include one or more fastener assemblies. U.S. Pat. No. 6,827,531 discloses a slidable, retainable fastener assembly for attaching to a track that is mounted to or near a truck bed. The fastener assembly includes an anchor portion and a bottom portion. The anchor portion includes one or more eyelets, hooks, rings, carabiners, clamps, clasps, or other suitable tie-down members. The bottom portion slides within the track slot. The bottom portion includes a retainer that engages a pair of opposing extension positioned on the track upper, open portion. The retainer includes a pair of upper surfaces specially contoured to conform to the ribs and abscesses on each extension. 
   Other cargo securing systems utilize tracks that are integral with the cargo bed floor. U.S. Pat. No. 6,712,568 discloses a cargo bed having a pair of integral tracks within the cargo bed floor and a tie-down system that uses the integral tracks. The tracks include channels that essentially extending lengthwise along the cargo bed base. The channels receive fittings that facilitate the attachment of various objects to the cargo bed. Unfortunately, the cargo securing system cannot be used with a truck bed liner that covers the entire cargo bed floor. 
   U.S. Pat. No. 6,511,270 discloses a cargo clamp system that can be used with a truck bed liner that covers the entire cargo bed floor. The bed liner includes a plurality of corrugations that define a plurality of troughs extending lengthwise along the bed liner base. The clamp system includes a pair of jaws that attach the clamp system to the bed liner. Unfortunately, the existing cargo clamp system must be used with a bedliner that includes corrugations. Accordingly, there is a need for an improved cargo securing system that can be used with corrugated or non-corrugated bed liners.

   DESCRIPTION OF THE PREFERRED EMBODIMENTS 
   Referring to the drawings and particularly to  FIG. 1 , there is illustrated a conventional pickup truck generally designated by the numeral  10  having an operator&#39;s cab  12  and a cargo bed  14 . The cargo bed  14  includes a floor or bottom wall  16 , two oppositely positioned side walls  18 ,  20 , and a front wall  22 . The cargo bed  14  also includes a tailgate  24  which forms with the bottom wall  16 , the side walls  18 ,  20 , and the front wall  22  a cargo compartment generally designated by the numeral  26  for the storage of cargo. 
   As is well known in the art, the bottom wall  16  may be substantially planar and may include a plurality of ridges to facilitate drainage of water or other liquids from the cargo bed. The side walls  18 ,  20  extend vertically from the bottom wall  16  in spaced parallel relationship. Each side wall  16 ,  18  includes a top rail  28 ,  30  extending longitudinally the length of the bed. The structure of the side walls  18 ,  20 , front wall  22  and top rails  28 ,  30  vary considerably between different makes and models of trucks as to dimensions and configuration. 
   The cargo bed  14  conventionally includes a bed liner  32  for protecting the cargo compartment  26 . The bed liner  32  is positioned in the cargo bed  14  to cover the front wall  22 , bottom wall  16 , and side walls  18 ,  20 . The bed liner  32  includes a bottom wall  34  that is adapted to fit on and substantially cover the full length and width of the cargo bed bottom wall  14 . The liner bottom wall  34  normally has a width substantially as great as the distance between the truck bed rails  28 ,  30 . In a conventional manner, the liner bottom wall  34  includes a plurality of separate inverted U-shaped longitudinal corrugations. 
   Referring now to  FIGS. 2-5 , there is illustrated a cargo bed liner generally designated by the numeral  36  corresponding to a preferred embodiment of the present invention. The bed liner  36  includes a bottom wall member or base  38  and a plurality of panels  40 ,  42 ,  44  that extend upwardly from the base  28 . Each of the panels  40 ,  42 ,  44  is connected to the base  38 . The panels  40  and  42  are side wall members. The panel  44  is a front wall member. In the preferred embodiment, the panels  40 ,  42 ,  44  are integrally molded with the base  38 . 
   The side panels  40 ,  42  are integrally formed with the base  38  to conform to the inner contours of the side walls  18 , shown in  FIG. 1 . The panels  40 ,  42  include outer surfaces  46 ,  48 . Each side wall  40 ,  42  includes a wheel well  50 ,  52  that is extends upwardly from the base  38 . The wheel wells  50 ,  52  are adapted to accommodate truck cargo bed rear wheel wells (not shown). 
   The front panel  44  is integrally formed with the base  38  to conform, so that an outer surface  54  conforms to the inner contour of the front wall  22  shown in  FIG. 1 . The panel  44  also includes an inner surface  56  that connects to an upper surface  58  on the base  38  to form a continuous surface for the bed liner  32 . The front wall member  44  connects the two side wall members  40 ,  42  to one another, so that the bed liner  32  is complementary with the cargo bed  12  at the front wall, side walls  16  and  18  and bottom wall  14  to completely cover and protect the surfaces of the cargo bed  12 . 
   Referring now to  FIGS. 2-6 , the base  38  includes a front edge  60  and a rear edge  62 . A pair of C-shaped channels  64 ,  66  essentially extends from the base front edge  60  to the base rear edge  62 . The channels  64 ,  66  are essentially aligned parallel to the corrugations in the base  38 . The channels  64 ,  66  connect to and communicate with a pair of trapezoid shaped slots  68 ,  70  in the front wall member inner surface  56 . The channels  64 ,  66  and the slots  68 ,  70  form a pair of continuous tracks  72 ,  74 . 
   The tracks  72 ,  74  are formed during the manufacture of the bed liner  36 . The bed liner  36  is made from any suitable material and is fabricated through any conventional manufacturing process, such as thermoforming, profile extrusion, injection molding, blow molding, or rotational molding. The bed liner  36  is preferably formed of high density polyethylene in a single, integral unit. 
   In the preferred embodiment, the bed liner  36  is manufactured using a thermoforming process in which a sheet of moldable material is heated to a suitable temperature for molding. The moldable material includes a plurality of panel forming sections that extend from a base forming section. 
   The sheet is heated until the material is sufficiently softened, so that material can be moved from the panel forming sections to a base forming section. Once the sheet is sufficiently softened, a portion of the moldable material is pushed from at least one of the panel forming sections to the base forming section. The additional material provides sufficient material to facilitate the formation of the channels  64 ,  66  within the base  38 . 
   Next, the sheet is draped over a mold to form the base  38  from the base forming section. The panels  40 ,  42 ,  44  and the wheel wells  50 ,  52  are formed from the panel forming sections. The front member panel  44  is deformed to include the slots  68 ,  70 , so that the channels  64 ,  66  and the slots  68 ,  70  form the tracks  72 ,  74 . 
   As shown in  FIGS. 4 and 5 , the front member panel inner surface  56  includes a pair of indentations  76 ,  78  that define the slots  68 ,  70 . The formation of the indentations  76 ,  78  during the molding process causes the outer surface  54  to extend outwardly or protrude from the front wall panel  44  to form a pair of protrusions  80 ,  82  (shown in  FIGS. 2 ,  4 , and  8 ). The protrusions  80 ,  82  permit the tracks  72 ,  74  to extend beyond the base front edge  60  to the front wall panel  44 . This expands the range of the tracks  72 ,  74  for securing cargo in the vehicle cargo compartment  26 . The tracks  72 ,  74  do not extend above the base upper surface  58 . 
   Referring now to  FIGS. 9 and 10 , the bed liner  36  is part of a cargo securing system generally designated by the numeral  84 . The cargo securing system  84  also includes a pair of rails  86 ,  88  and a pair of tie down devices  90 ,  92  (shown in  FIG. 9 ) for insertion into the rails  86 ,  88 . The rails  86 ,  88  are inserted into the tracks  72 ,  74  for connection to the bed liner  36 . Preferably, the rails  86 ,  88  do not extend above the base upper surface  58 . 
   As shown in  FIG. 9 , the tie-down device  90 ,  92  includes bottom portions  94 ,  96  and anchors  98 ,  100 . The anchors  98 ,  100  extend upwardly from the bottom portion  94 ,  96  to facilitate connection to one or more ropes (not shown). The bottom portions  94 ,  96  conform to the inner contour of the rails  86 ,  88 , so that the tie-down devices  90 ,  92  slide within the tracks  72 ,  74 . 
   As shown in  FIG. 10 , the rails  86 ,  88  include a plurality of slots or holes  102  to facilitate repositioning of the tie-down devices  90 ,  92  within the tracks  72 ,  74 . 
   It should be understood that alternative tie-down devices are contemplated in accordance with the present invention that include one or more eyelets, hooks, rings, carabiners, clamps, clasps, or other suitable tie-down members. 
   According to the provisions of the patent statutes, I have explained the principle, preferred construction and mode of operation of my invention and have illustrated and described what I now consider to represent its best embodiments. However, it should be understood that, within the scope of the appended claims, the invention may be practiced otherwise than as specifically illustrated and described.
