Background-o~ the Invention Ihis invention relates to a molded truck liner for a truck bed.
Molded plastic truck bed liners are known in the art as evidenced by the Lorenzen United States Patent No. 3,814,473, issued June 4, 1974, and the Nix United States Patent No. 3,8~1,768, issued May 6, 1975.
However, difficulties have been experienced in molding a unitary plastic truck bed liner including an integral tailgate liner as illustrated in the Nix Patent 3,881,768. ~urthermore, where the tailgate liner is made in-dependent and separate from the rest of the truck bed liner, separate and in- `~
dependent fastener members, such as screws, bolts or rivets, must be provided, not only for securing the bed liner per se to the truck bed, but also for securing the tailgate liner to the tailgate.
Furthermore, where the truck bed liner is molded to completely con-form to the correspondlng interlor surfaces of the walls of the-truck bed, any condensation between the liner walls and the walls of the truck bed is trapped, causing condensation, rusting and corrosion.
In accordance w~th the invention, there is provided a protective ; :Liner for a truck bed, said bed having a bottom waLl, a front wall, and opposed side waLls, said side walls having ].ongitudinc~lly extending top ; ~edges, said liner compri~ing;

the line 5-5 f Figure 2, Figure 6 is an enlarged, fragmentary, exploded, perspeckive view of the upper left rear corner of the truck bed liner and the truck bed, and the fastener member therefor; and Figure 7 is an enlarged, frag~.entary section taken along the line 7-7 of Figure 6, disclosing the liner fastened to the truck bed.
Description of the Preferred Embodiment Referring now to the drawings in more detail, Figure 1 discloses a conventional pick-up truck 10, including a cab 11 and a truck bed or cargo compartment 12 supported upon wheels 13. The bed 12 includes a bottom wall 15 having elongated ribs 16, a front wall 17 and opposed side walls 18 and 19. A tailgate 20 having an i~terior surface and an exterior surface, is mounted upon a h:Lnge pin 21 for swinging movement about a horizontal axis between the open position disclosed in Figure 3 and the closed position dis-closed ~n ~lgure ~I. The tailgate 20 may be ~Irther supported by the toggle link bar assembl:Les 23, disclosed in Fi~ure 1.
The truck bed liner 25 made in accordance with this invention in-cludes a unitary molded body liner 26 and a unitary molded tailgate liner 27, each separately formed and unconnected, except through the hinge pin 21 be-tween the truck bed 12 and the tailgate 20.
The truck body liner 26 includes a bottom wall 30, a front wall 31, and opposed side ~alls 32 and 33. All the walls 30, 31, 32 and 33 are integrally form~d, such as by molding from plastic material. The pk~stlc material used to m.old both the body portion 26 and the tailgate liner 27 is preferably a durable, hi~h-impact styrene sheet material, such as ABS
(Acrylonitrile Butadiene Styrene - Trade Mark) and more particularly made of ABS-LS (Trade Mark) plastic, ~hich is a more durable acrylonitrile butadiene styrene ~heet ~aterial including an additive or ~lller known in the trade as ~'LS~'. The plastic materi~l ls pre~erably 300 mils thick, and ~ `

also preferably laninated or covered with a "KORAD" (Trade Mark) film to function as an ultra-violet ray inhibitor to prolong the life of the plastic material against the ultra-violet rays from the sun.
The walls 30, 31, 32 and 33 substantially conform to the in-terior surfaces of the corresponding bottom wall 15, front wall 17, and side walls 18 and 19 of the truck bed 12.
Each of the side walls 32 and 33 and the front wall 31 are provided with top flanges 35 pro~ecting substantially horizontally outward in order to protect the upper surfaces of the corresponding side walls 18 and 19 and front wall 17 of the truck bed 12.
Although various types of fastening means may be employed to secure the truck bed body liner 26 to the truck bed 12, nevertheless one preferred form of toggle bolt fastener is disclosed in Figures 6 and 7 in the form of a threaded bolt 37 adapted to cooperate with an internally threaded collar 38 having expanding locking arms 39. As illustrated in Figures 6 and 7, the bolt 37 is inserted through a corresponding hole in the top flange 35 of either of the side walls 32 or 33 and is threadedly se-cured to the nut 38. As the body liner 26 is lowered into the truck bed 12, the expanded arms 39 are collapsed by engagement with the edges o~ the hole 40 in the corresponding ledge 41 of the side walls 18 or 19. After the collapsed arms 39, nut 38 and bolt 37 have extended below and cleared the hole 40, the arms 39 are a~tomatically expanded by springs, not shown, to their position disclosed in Figure 7. The bolt 37 is then tightened within the nut 38 to securely hold the top flange 35 to the corresponding ledge 41 of the respective side walls 18 and 19 of the truck bed 12, as disclosed in Figure 7.
In a prefbrred form of the invention, the bottom wall 30 of the boc~y liner 26 ls provided with uniformly and transversely spaced elongated - . . . :- . , :

13~
ridge members 43 extending the entire length of the bottom ~lall 30~ open-ing downward, and preferably opening forward to merge with the like ridge men~bers 44 formed in the front wall 31 of the body liner 26.
Moreover, if the bottom liner wall 30 rests upon a bottom wall 15 is a truck bed 12 which has longitudinal rib members 16, each ridge member 43 is designed to have a slightly greater height and slightly greater width than a corresponding rib member 16 received by the ridge .ember 43, to provide ventilation space 45 between the ridge ~ember 43 and the corresponding rib member 16, as best disclosed in Figures 2 and 3. If the bottom bed wall 15 is flat, then the ventilation space l15 is sub-stantlally greater.
This ventilation space 45 is essential for the elimination or mlnlmization of condensation and moisture which othe~se might become trapped between closely-fitting, complementar~ liner ridge members and truck bed rib men~ers.
For the same reason, a ventilation space 46 is provided be-tween the front liner wall 31 and the front bed wall 17, as best disclosed in Figure 3.
1`he tailgate liner 27 includes a central panel portion 48 having a front face, a rear face, an elongated top portion, and an elong-ated bottom portion. The elongated top portion merges into a top hoolc-shaped flange 49, while the elongated bottom portion of the tailgate panel portion 48 mer~es into a bottom hook-shaped flange 50. Both of the hook-shaped flanges 49 and 50 pro~ect rearward from the central panel portion L18 and are adapted to extend over or across and then slightly behind corres-ponding top and bottom edge surfaces 51 and 52, respectively, of the tail-gate 28~ as best disclosed .~n Figure 3. The hook-shaped flanges ll9 and 50 are adapted to closely fit and receive the corresponding top and bottom `:
.. , : . . . :
.
surfaces 51 and 52 of the tailgate 20, so that when one of the hook-shaped flanges 49 or 50 has been fitted over the corresponding surface 51 or 52, the rem~ining or other hook-shaped flange 50 or 49 is manually forced, with a moderate degree of pressure, over its corresponding engaging surface 52 or 51, until the other flange is snap-fastened over the corresponding surface, to firmly hold the tailgate liner 27 securely in place to completely cover the interior surface of the rectangular-shaped tailgate 20.
Ihe bottom edge surface 52 of the tailgate 20 is substantially a circular or cylindrical surface having its center of curvature sub-stantially coinciding with the pivotal axis of the hinge 21, so that therewill be a substantially close fit between the bottom surface 52 and the end surface 54 of the bottom wall 15 of the truck bed 12, regardless of the plvotal position of the tail~ate 20. Thus, where the ed~;e sur.~ace 52 is substantlally c:lrcular, the corresponding hool~-shaped flange 50 ls also circular and extends through an arc of at least 90. The extent of the arc of circular hook-shaped flange 50 greater than 90 is only enough to permit the flan~e 50 to be snapped over the arcuate edge surface 52 with a moderate ~ `
amount of manually applied pressure, and yet firmly hold the tailgate liner 27 snugly upon the tailgate 20. Ihe exten~ of the curvature of the bottom hook-shaped flange 50 will of co~1rse depend upon the resilience of the central panel portion 48, which in turn depends upon the elasticity of the plastic materlal, the wall thickness of the panel portion 4~ and the rigid-ity of the central panel portion 48, which in turn depends upon its inherent reinforcing struct~e.
In a preferred forn of the invention, the central panel portlon 48 comprises a plurality of longitudinally spaced rib members 55 which ex-tend transversely of the tailgate 20, or in other words are disposed vertically when the tailga~e 20 is in an upr:L~ht position, to improve the ~ . ~ . - . :. .
L3~
impact resistance o~ the tailgate liner 27 and to improve the strength and rigidity of the tailgate liner 27.
The central panel portion 48 is also preferably provided with an enlarged, lower rib member 56, preferably intersecting with the trans-verse rib members 55, and preferably having coplanar interior s~rfaces.
The lower rib menber 56 is preferably located to oppose, in close juxta-postion, the rear edge of the bottom liner wall 30, to minimize the space between the tailgate liner 27 and the bed body liner 26~ to prevent small articles from leaking or falling from the truck bed 12, when the tailgate 20 ls in closed position, as disclosed in Figure 4.
Moreover, the lower rib member 56 provides an elongated stop or buffer in the lower rear end of the body liner 26, where impact from obJects within the truck bed 12 are most likely to occur.
The body liner 26 may be provided wlth slight dra.~ts in the glde walls 32 and 33 and the front wall 31, relative to the bottom wall 30, to permit nesting or stacking of a plurality of the body liners 26, in order to economize space in storage or sh_pment of the body liners 26.
Furthermore, the plastic mater:lal from which the body liner 26 and tailgate liner 27 are made, ma~ have appropFlate pigments or colouring 20 material added in order to enhance the appearance of the liners 26 and 27.
In the preferred form of the invention, the liners 26 and 27 are pre~erably vacu~formed from the AES-LS (Trade Mark) plastic sheet material.

Description of the Preferred Embodiment Referring now to the drawings in more detail, Figure 1 discloses a conventional pick-up truck 10, including a cab 11 and a truck bed or cargo compartment 12 supported upon wheels 13. The bed 12 includes a bottom wall 15 having elongated ribs 16, a front wall 17 and opposed side walls 18 and 19. A tailgate 20 having an i~terior surface and an exterior surface, is mounted upon a h:Lnge pin 21 for swinging movement about a horizontal axis between the open position disclosed in Figure 3 and the closed position dis-closed ~n ~lgure ~I. The tailgate 20 may be ~Irther supported by the toggle link bar assembl:Les 23, disclosed in Fi~ure 1.
The truck bed liner 25 made in accordance with this invention in-cludes a unitary molded body liner 26 and a unitary molded tailgate liner 27, each separately formed and unconnected, except through the hinge pin 21 be-tween the truck bed 12 and the tailgate 20.
The truck body liner 26 includes a bottom wall 30, a front wall 31, and opposed side ~alls 32 and 33. All the walls 30, 31, 32 and 33 are integrally form~d, such as by molding from plastic material. The pk~stlc material used to m.old both the body portion 26 and the tailgate liner 27 is preferably a durable, hi~h-impact styrene sheet material, such as ABS

also preferably laninated or covered with a "KORAD" (Trade Mark) film to function as an ultra-violet ray inhibitor to prolong the life of the plastic material against the ultra-violet rays from the sun.
The walls 30, 31, 32 and 33 substantially conform to the in-terior surfaces of the corresponding bottom wall 15, front wall 17, and side walls 18 and 19 of the truck bed 12.
Each of the side walls 32 and 33 and the front wall 31 are provided with top flanges 35 pro~ecting substantially horizontally outward in order to protect the upper surfaces of the corresponding side walls 18 and 19 and front wall 17 of the truck bed 12.
Although various types of fastening means may be employed to secure the truck bed body liner 26 to the truck bed 12, nevertheless one preferred form of toggle bolt fastener is disclosed in Figures 6 and 7 in the form of a threaded bolt 37 adapted to cooperate with an internally threaded collar 38 having expanding locking arms 39. As illustrated in Figures 6 and 7, the bolt 37 is inserted through a corresponding hole in the top flange 35 of either of the side walls 32 or 33 and is threadedly se-cured to the nut 38. As the body liner 26 is lowered into the truck bed 12, the expanded arms 39 are collapsed by engagement with the edges o~ the hole 40 in the corresponding ledge 41 of the side walls 18 or 19. After the collapsed arms 39, nut 38 and bolt 37 have extended below and cleared the hole 40, the arms 39 are a~tomatically expanded by springs, not shown, to their position disclosed in Figure 7. The bolt 37 is then tightened within the nut 38 to securely hold the top flange 35 to the corresponding ledge 41 of the respective side walls 18 and 19 of the truck bed 12, as disclosed in Figure 7.
In a prefbrred form of the invention, the bottom wall 30 of the boc~y liner 26 ls provided with uniformly and transversely spaced elongated - . . . :- . , :

Moreover, if the bottom liner wall 30 rests upon a bottom wall 15 is a truck bed 12 which has longitudinal rib members 16, each ridge member 43 is designed to have a slightly greater height and slightly greater width than a corresponding rib member 16 received by the ridge .ember 43, to provide ventilation space 45 between the ridge ~ember 43 and the corresponding rib member 16, as best disclosed in Figures 2 and 3. If the bottom bed wall 15 is flat, then the ventilation space l15 is sub-stantlally greater.
This ventilation space 45 is essential for the elimination or mlnlmization of condensation and moisture which othe~se might become trapped between closely-fitting, complementar~ liner ridge members and truck bed rib men~ers.
For the same reason, a ventilation space 46 is provided be-tween the front liner wall 31 and the front bed wall 17, as best disclosed in Figure 3.
1`he tailgate liner 27 includes a central panel portion 48 having a front face, a rear face, an elongated top portion, and an elong-ated bottom portion. The elongated top portion merges into a top hoolc-shaped flange 49, while the elongated bottom portion of the tailgate panel portion 48 mer~es into a bottom hook-shaped flange 50. Both of the hook-shaped flanges 49 and 50 pro~ect rearward from the central panel portion L18 and are adapted to extend over or across and then slightly behind corres-ponding top and bottom edge surfaces 51 and 52, respectively, of the tail-gate 28~ as best disclosed .~n Figure 3. The hook-shaped flanges ll9 and 50 are adapted to closely fit and receive the corresponding top and bottom `:

surfaces 51 and 52 of the tailgate 20, so that when one of the hook-shaped flanges 49 or 50 has been fitted over the corresponding surface 51 or 52, the rem~ining or other hook-shaped flange 50 or 49 is manually forced, with a moderate degree of pressure, over its corresponding engaging surface 52 or 51, until the other flange is snap-fastened over the corresponding surface, to firmly hold the tailgate liner 27 securely in place to completely cover the interior surface of the rectangular-shaped tailgate 20.
Ihe bottom edge surface 52 of the tailgate 20 is substantially a circular or cylindrical surface having its center of curvature sub-stantially coinciding with the pivotal axis of the hinge 21, so that therewill be a substantially close fit between the bottom surface 52 and the end surface 54 of the bottom wall 15 of the truck bed 12, regardless of the plvotal position of the tail~ate 20. Thus, where the ed~;e sur.~ace 52 is substantlally c:lrcular, the corresponding hool~-shaped flange 50 ls also circular and extends through an arc of at least 90. The extent of the arc of circular hook-shaped flange 50 greater than 90 is only enough to permit the flan~e 50 to be snapped over the arcuate edge surface 52 with a moderate ~ `

The lower rib menber 56 is preferably located to oppose, in close juxta-postion, the rear edge of the bottom liner wall 30, to minimize the space between the tailgate liner 27 and the bed body liner 26~ to prevent small articles from leaking or falling from the truck bed 12, when the tailgate 20 ls in closed position, as disclosed in Figure 4.
Moreover, the lower rib member 56 provides an elongated stop or buffer in the lower rear end of the body liner 26, where impact from obJects within the truck bed 12 are most likely to occur.
The body liner 26 may be provided wlth slight dra.~ts in the glde walls 32 and 33 and the front wall 31, relative to the bottom wall 30, to permit nesting or stacking of a plurality of the body liners 26, in order to economize space in storage or sh_pment of the body liners 26.
