Abstract
A blow-molded unitary structure includes a panel having upper and lower panel surfaces and a ridge extending downward beyond the lower panel surface. The ridge includes a first side surface, a second side surface, and a lower ridge surface joined with the first side and second side surfaces of the ridge. The ridge further includes a plurality of depressions formed at one or more of the first side surface, second side surface and lower ridge surface. The plurality of depressions enhances the strength of the ridge, and the ridge in turn enhances the strength of the structure.
Claims20
A blow-molded unitary structure comprising:
- a panel comprising upper and lower panel surfaces;
- a ridge extending downward beyond the lower panel surface, the ridge comprising:
- a first side surface;
- a second side surface;
- a lower ridge surface joined with the first side and second side surfaces of the ridge;
- and
- a plurality of depressions formed at one or more of the first side, second side and lower ridge surfaces to enhance a strength of the ridge, the plurality of depressions comprising a plurality of first depressions spaced apart along a length direction of the ridge, each first depression recessed from the lower ridge surface toward the upper panel surface.
A blow-molded unitary structure comprising:
- a panel comprising upper and lower panel surfaces;
- a ridge extending downward beyond the lower panel surface, the ridge comprising:
- a first side surface;
- a second side surface;
- a lower ridge surface joined with the first side and second side surface of the ridge;
- and
- a plurality of depressions formed at one or more of the first side, second side and lower ridge surfaces to enhance a strength of the ridge, the plurality of depressions comprising:
- one or more first depressions and one or more second depressions spaced apart along a length direction of the ridge and each recessed from the lower ridge surface toward the upper panel surface;
- and
- one or more third depressions at or adjacent to an edge between the lower ridge surface and first side surface of the ridge such that each third depression in the one or more third depressions is recessed from the lower ridge surface toward the lower panel surface of the panel and recessed from the first side surface toward the second side surface of the ridge,
- wherein a respective third depression in the one or more third depression is formed in between a corresponding first depression in the one or more first depressions and a corresponding second depression in the one or more second depressions, or in between two adjacent first depressions, or in between two adjacent second depressions.
A blow-molded unitary structure comprising:
- a panel comprising upper and lower panel surfaces;
- a ridge extending downward beyond the lower panel surface, the ridge comprising:
- a first side surface;
- a second side surface;
- a lower ridge surface joined with the first side and second side surface of the ridge;
- and
- a plurality of depressions formed at one or more of the first side, second side, and lower ridge surfaces to enhance a strength of the ridge, the plurality of depressions comprising:
- a third depression formed at or adjacent to an edge between the lower ridge surface and first side surface of the ridge such that the third depression is recessed from the lower ridge surface toward the lower panel surface of the panel and recessed from the first side surface toward the second side surface of the ridge;
- and
- a fourth depression recessed from the first side surface toward the second side surface of the ridge at a location adjacent to the lower panel surface and joined with the third depression.
