Abstract
Abstract A truck bed liner comprising a tailgate liner having top and bottom hook-shaped flanges adapted to conform to and receive the top and bottom edge surfaces of the tailgate of a truck bed so that the tailgate liner may be snap-fastened to cover the interior surface of the tailgate, without any separate or independent fastener members. The truck bed liner also includes transversely spaced longitudinal rib members having widthwise dimensions greater than the width of any longitudinal rib members on the bottom wall of a truck bed, to provide longitudinal ventilation spaces between the bottom wall of the truck bed liner and the bottom wall of the truck bed.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
138 words
A protective liner for a truck bed having a bottom wall, a front wall, and opposed side walls, said bottom wall comprising a plurality of transversely spaced longitudinal rib members extending front-to-rear of the truck bed, comprising: (a) bottom liner wall adapted to rest upon and to cover the bottom wall of said truck bed, (b) said bottom liner wall comprising transversely spaced, front-to-rear extending, raised, ridge members opening downward, (c) there being one ridge member for each rib member, each ridge member being in substantial longitudinal alignment with each corresponding rib member, (d) the width of each ridge member being greater than the width of the corresponding longitudinally aligned rib member to provide longitudinal ventilating spaces between said ridge members and the bottom wall of said truck bed when said bottom liner wall covers said bottom wall.
Claim 2
Dependent Claim
138 words
A protective liner for a truck bed having a bottom wall, a front wall, and opposed side walls, said bottom wall comprising a plurality of transversely spaced longitudinal rib members extending front-to-rear of the truck bed, comprising: (a) bottom liner wall adapted to rest upon and to cover the bottom wall of said truck bed, (b) said bottom liner wall comprising transversely spaced, front-to-rear extending, raised, ridge members opening downward, (c) there being one ridge member for each rib member, each ridge member being in substantial longitudinal alignment with each corresponding rib member, (d) the width of each ridge member being greater than the width of the corresponding longitudinally aligned rib member to provide longitudinal ventilating spaces between said ridge members and the bottom wall of said truck bed when said bottom liner wall covers said bottom wall.
Claim 3
Dependent Claim
45 words
The invention according to claim 1 in which the height of each ridge member is slightly greater than the height of its corresponding covered rib member to provide an elongated upper ventilating space between the top of said rib member and its corresponding ridge member.
Claim 4
Dependent Claim
