Abstract
Abstract A truck box access apparatus adapted to be mounted along the inside of the lower sill of the truck comprising a pair of spaced vertical parallel support bars having brackets at one end of each of the bars for mounting the apparatus along the inside of the lower sill of a truck body. A pair of cross bars are disposed at the other end of each of the support bars. The cross bars extend between the support bars and are spaced from each other. A step platform is slidably supported between the cross bars and between first and second extreme positions. The step platform in its first extreme position extends outwardly from the support bars and at a right angle thereto and in its second position is nested flush between the bars.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
158 words
A truck box access apparatus adapted to be mounted along the inside of the lower sill of the truck comprising a pair of spaced parallel support members (12, 14) means (16, 18) at one end of each of said support members for mounting said apparatus along the inside of the lower sill, a first (20) and a second (22) cross bar disposed at the other end of each said support members, said first and said second cross bars extending between said support members and being spaced from each other, both longitudinally and transversely with respect to the longitudinal direction of the support members, a step platform (24) slidably supported between said first and said second bars and between first and second extreme positions, said step platform in its first extreme position extending outwardly from said support members and at a right angle thereto and said step platform in its second position being nested flush between said support members.
Claim 2
Dependent Claim
158 words
A truck box access apparatus adapted to be mounted along the inside of the lower sill of the truck comprising a pair of spaced parallel support members (12, 14) means (16, 18) at one end of each of said support members for mounting said apparatus along the inside of the lower sill, a first (20) and a second (22) cross bar disposed at the other end of each said support members, said first and said second cross bars extending between said support members and being spaced from each other, both longitudinally and transversely with respect to the longitudinal direction of the support members, a step platform (24) slidably supported between said first and said second bars and between first and second extreme positions, said step platform in its first extreme position extending outwardly from said support members and at a right angle thereto and said step platform in its second position being nested flush between said support members.
Claim 3
Dependent Claim
26 words
A truck box as set forth in claim 1 wherein said platform step includes first stop means (26, 28) for limiting outward extension of said step.
Claim 4
Dependent Claim
26 words
A truck box as set forth in claim 2 wherein said platform step includes second stop means (30, 32) for limiting inward extension of said step.
Claim 5
Dependent Claim
62 words
A truck box as set forth in claim 3 wherein said first stop means and said second stop means comprise respectively, a first (26, 28) and a second (30, 32) set of lugs disposed at opposite sides of said platform and depending therefrom, said first and said second set of lugs being positioned on opposite sides of said second cross bar (22).
Claim 6
Dependent Claim
71 words
A truck box as set forth in claim 3 wherein said first stop means includes a first set of lugs depending from said platform, said second stop means includes a second set of lugs depending from said platform, said lugs being spaced from each other such that said first set limits the outward extent of said step and said second set limits the extent of said step in its second position.
Claim 7
Dependent Claim
103 words
A truck box as set forth in claim 1 wherein said support members are oriented in a vertical plane, said step being nested in the plane of said support members when in its second extreme position and being in a horizontal plane, when in said first extreme position, said first bar (20) extending over said step (24) and adjacent one edge thereof when said step is in its first extreme position and said second bar (22) extending beneath said step and spaced fron said one edge such that the said step may pivot about said bar when being moved between said extreme positions.
Claim 8
Dependent Claim
61 words
A truck box as set forth in claim 6 including a stop means depending from said step to limit slidable movement of the platform, said stop means being positioned to one side of the center of said step so as to permit said step to pivot about said second cross bar after limited slidable movement away from its first extreme position.
Claim 9
Dependent Claim
61 words
A truck box as set forth in claim 1 including a stop means depending from said step to limit slidable movement of the platform, said stop means being positioned to one side of the center of said step so as to permit said step to pivot about said second cross bar after limited slidable movement away from its first extreme position.
