Abstract
A one-piece dunnage bar for a dunnage rack of the type used to store and transport parts within an automotive factory. The dunnage bar includes integral inner and outer C-shaped portions roll-formed from a single piece of structural metal. The inner and outer portions each include overlying wall segments that cooperate to define the mouth of the C shape. The thickness of each of these wall segments is one-half of the thickness of the remainder of the walls so that the pancaked wall segments have a combined thickness approximately the same as that of the remaining walls.
Claims8
A one-piece dunnage rack bar comprising:
- a generally C-shaped outer portion;
- and
- a generally C-shaped inner portion integral with and substantially surrounded by said outer portion, said inner portion and said outer portion together defining a mouth;
- said inner portion including a pair of inner wall segments defining said mouth;
- said outer portion including a pair of outer wall segments defining said mouth, each of said outer wall segments integrally connected to one of said inner wall segments along a fold line, each of said outer wall segments overlying engaging one of said inner wall segments;
- and
- each of said inner and outer portions having a generally uniform wall thickness except at said inner and outer wall segments, each of said inner and outer wall segments having a reduced wall thickness substantially less than the uniform wall thickness.
A one-piece bar for a dunnage rack of the type used in an automotive factory, said bar comprising:
- an outer portion having a generally C-shaped cross section to define an outer mouth extending along the length of said outer portion;
- and
- an inner portion integral with said outer portion, said inner portion having a generally C-shaped cross section to define an inner mouth extending along the length of said inner portion, said inner mouth being coextensive with said outer mouth;
- said inner and outer portions having a standard wall thickness;
- said inner portion including a pair of spaced-apart inner wall segments defining said inner mouth and each having a reduced thickness substantially less than said standard wall thickness;
- and
- said outer portion including a pair of spaced-apart outer wall segments defining said outer mouth and each having a reduced thickness substantially less than said standard wall thickness.
A one-piece dunnage bar for a dunnage rack, comprising:
- an outer portion generally rectangular in cross section and including three generally closed sides and a fourth side defining a mouth;
- and
- an inner portion integral with and substantially enclosed by said outer portion, said inner portion being generally rectangular in cross section and including three generally rectangular sides and a fourth side defining a mouth, said mouth of said inner portion being substantially coextensive with said mouth of said outer portion;
- said outer and inner portions having a standard wall thickness;
- said mouth of said inner portion being defined by a pair of spaced-apart wall segments each having a thickness substantially one half of said standard wall thickness;
- and
- said mouth of said outer portion being defined by a pair of spaced-apart wall segments each having a thickness substantially one half of said standard wall thickness.
