Abstract
An ergonomic aid has a base portion configured to be received on a stringer adjacent an access port in a partition wall within a structural enclosure. A support pad extends from the base portion, the support pad having an upper surface with a contour adapted to match a profile of the access port. The support pad has a predetermined height to extend the upper surface above a rim of the access port opening when the support pad is in a compressed condition.
Claims20
An ergonomic aid comprising:
- a base portion configured to be received on a stringer adjacent an access port in a partition wall within a structural enclosure;
- and,
- a support pad extending from the base portion, said support pad having an upper surface with a contour configured to match a profile of the access port said support pad having a predetermined height matching the upper surface with a rim of the access port opening when said support pad is in a compressed condition.
An ergonomic aid comprising:
- two space-apart base portions, each being not more than a predetermined thickness that is sufficient to be received against a web between two flanges of a stringer that is mounted proximate an access port in a partition wall within a structural enclosure;
- a support pad extending from the two base portions and having central portion spanning the two base portions, said central portion having a predetermined minimum thickness of at least 0.50 inches,
- wherein the support pad has an arcuate upper surface with an arcuate contour that generally conforms a rim profile of the access port, such that when the two base portions are positioned against a web between two flanges of a stringer an upper surface of the support pad is above the stringer flanges and conforms to the rim profile of the access port, wherein a lip of the support pad at least partially overlaps the top of at least one flange of the stringer.
A method for installation and use of an ergonomic aid for access port passthrough, the method comprising:
- inserting an ergonomic aid on a stringer;
- engaging a web on the stringer with a bottom surface of a base portion;
- and,
- aligning an arcuately contoured upper surface of a support pad extending from the base portion with a lower periphery of a rim profile of an access port.
