Independent Claim 91 words
For a truck having a truck frame and a truck box pivotally attached to the truck frame, a liner adapted to be positioned within the truck box including a front section and a pair of side walls, the front section comprising a pair of vertical side frame members, tubular members attached to the vertical side frame members, horizontal bar members slidably positioned within the tubular members, a vertical bar attached to the horizontal bar members, and overlapping panel members attached to the vertical side frame members and to the tubular members.
Claim 2
Dependent Claim 91 words
For a truck having a truck frame and a truck box pivotally attached to the truck frame, a liner adapted to be positioned within the truck box including a front section and a pair of side walls, the front section comprising a pair of vertical side frame members, tubular members attached to the vertical side frame members, horizontal bar members slidably positioned within the tubular members, a vertical bar attached to the horizontal bar members, and overlapping panel members attached to the vertical side frame members and to the tubular members.
Claim 3
Dependent Claim 124 words
For a truck having a truck frame and a truck box pivotally attached to the truck frame, a liner adapted to be positioned within the truck box including a front section and a pair of side walls, a tail gate pivotally supported by the side walls, a cable member attached to the tail gate and extending over the front section and adapted to be attached to the truck frame for opening action of the tail gate with pivotal movement of the truck box, the tail gate comprising horizontal tubular members, a plurality of horizontal bar members slidable within the horizontal tubular members, a vertical bar member joined to the horizontal bar members, and a plurality of panel members joined to the horizontal tubular members.
Claim 4
Dependent Claim 124 words
For a truck having a truck frame and a truck box pivotally attached to the truck frame, a liner adapted to be positioned within the truck box including a front section and a pair of side walls, a tail gate pivotally supported by the side walls, a cable member attached to the tail gate and extending over the front section and adapted to be attached to the truck frame for opening action of the tail gate with pivotal movement of the truck box, the tail gate comprising horizontal tubular members, a plurality of horizontal bar members slidable within the horizontal tubular members, a vertical bar member joined to the horizontal bar members, and a plurality of panel members joined to the horizontal tubular members.
