A nut in accordance with claim 1 wherein said bolt engaging means is threaded to accept a threaded bolt.

Claim 5

A fastener in combination with a channeled structural member; said fastener being used for affixing parts to said channeled structural member; said combination comprising said channeled structural member having a depth, a width, a bottom section, two parallel side sections, being spaced apart by a distance between said side sections, and a top section parallel with the bottom section, said top section having a longitudinal slot bordered by inwardly projecting flanges, said flanges each having an end portion, said flanges being spaced apart by a slot width distance; said fastener comprising a nut having a depth, a width, a length longer than its width, opposite parallel longitudinal side surfaces, end surfaces, a top major face, and an opposite bottom major face substantially perpendicular to said side surfaces, said nut having parallel grooves located on said top major face perpendicular to said parallel longitudinal side surfaces, said parallel grooves having flange engaging means therein for engaging said end portion of said flanges of said channeled structural member, said parallel grooves being spaced apart and centered on said top major face for co-acting with said flanges of said channeled structural member, said longitudinal side surfaces being contiguous with said end surfaces forming a first and a second set of diagonally opposite corners, said first set of diagonally opposite corners being foreshortened, said first set of diagonally opposite corners being spaced apart by a first set diagonal dimension, said first set diagonal dimension being sufficiently less than the distance between said parallel side sections of said channeled structural member to provide clearance between said first set of diagonally opposite corners and said parallel side sections during installation of said fastener, said nut having a centrally located bolt engaging means having an extended portion of said centrally located bolt engaging means above said top major surface of said nut, said nut having an overall thickness equal to said depth of said nut plus said extended portion, said extended portion having two sets of opposite parallel extended sides, said two sets of opposite parallel extended sides being contiguous with each other forming a third and a fourth set of diagonally opposite corners, said third set of diagonally opposite corners being foreshortened, said third set of diagonally opposite corners being spaced apart by a third set diagonal dimension, said third set diagonal dimension being sufficiently less than said slot width distance of said channeled structural member to provide clearance between said third set of diagonally opposite corners of said extended portion and said flanges of said channeled structural member during installation of said nut, said fourth set of diagonally opposite corners co-acting with said flanges during the installation of said nut providing an alignment of said parallel grooves with said end portion of said flanges of said channeled structural member; a spring arranged normal to said bottom major face being attached to said nut by a spring attachment means located on said bottom major face for attaching a tang of said spring to said nut.

Claim 6

A fastener in combination with a channeled structural member; said fastener being used for affixing parts to said channeled structural member; said combination comprising said channeled structural member having a depth, a width, a bottom section, two parallel side sections, being spaced apart by a distance between said side sections, and a top section parallel with the bottom section, said top section having a longitudinal slot bordered by inwardly projecting flanges, said flanges each having an end portion, said flanges being spaced apart by a slot width distance; said fastener comprising a nut having a depth, a width, a length longer than its width, opposite parallel longitudinal side surfaces, end surfaces, a top major face, and an opposite bottom major face substantially perpendicular to said side surfaces, said nut having parallel grooves located on said top major face perpendicular to said parallel longitudinal side surfaces, said parallel grooves having flange engaging means therein for engaging said end portion of said flanges of said channeled structural member, said parallel grooves being spaced apart and centered on said top major face for co-acting with said flanges of said channeled structural member, said longitudinal side surfaces being contiguous with said end surfaces forming a first and a second set of diagonally opposite corners, said first set of diagonally opposite corners being foreshortened, said first set of diagonally opposite corners being spaced apart by a first set diagonal dimension, said first set diagonal dimension being sufficiently less than the distance between said parallel side sections of said channeled structural member to provide clearance between said first set of diagonally opposite corners and said parallel side sections during installation of said fastener, said nut having a centrally located bolt engaging means having an extended portion of said centrally located bolt engaging means above said top major surface of said nut, said nut having an overall thickness equal to said depth of said nut plus said extended portion, said extended portion having two sets of opposite parallel extended sides, said two sets of opposite parallel extended sides being contiguous with each other forming a third and a fourth set of diagonally opposite corners, said third set of diagonally opposite corners being foreshortened, said third set of diagonally opposite corners being spaced apart by a third set diagonal dimension, said third set diagonal dimension being sufficiently less than said slot width distance of said channeled structural member to provide clearance between said third set of diagonally opposite corners of said extended portion and said flanges of said channeled structural member during installation of said nut, said fourth set of diagonally opposite corners co-acting with said flanges during the installation of said nut providing an alignment of said parallel grooves with said end portion of said flanges of said channeled structural member; a spring arranged normal to said bottom major face being attached to said nut by a spring attachment means located on said bottom major face for attaching a tang of said spring to said nut.
