Strut

Claim 2

An elongated strut having inwardly depending flanges disposed generally continuously along the length of the slot of said strut, said flanges being formed to receive and secure fittings inserted into the slot of said strut, wherein portions of said flanges depend from the lips of said strut and form opposing shelves at the top of the strut proximate the continuous slot of the strut and said inwardly depending flanges define an interior cavity with a cross-section having at its widest point a width greater than the width of the continuous slot of said strut and wherein the ends of said flanges project generally towards each other.

Claim 3

The elongated strut of claim 1 wherein said strut and said inwardly depending flanges are formed from a continuous piece of material.

Claim 4

The elongated strut of claim 1 further comprising removable alignment means disposed within the interior cavity defined by the flanges.

Claim 5

The elongated strut of claim 3 wherein said alignment means comprises an insert made from compressible material and formed to fill at least a portion of the interior cavity defined by the flanges.

Claim 6

An elongated strut having a generally flat back wall, side walls parallel to each other at least at the top section thereof, inturned lips from said side walls, and a continuous slot along the length of said strut between said lips, said elongated strut also having inwardly depending flanges disposed generally continuously along the length of said slot, said flanges formed to receive and secure fittings inserted into said slot and engaged with said flanges, whereby said fittings are removably secured by said flanges inside said strut and a first portion of each of said inwardly depending flanges projects generally toward the interior side wall of the strut adjacent to said flange and an end portion of each flange projects generally toward the interior back wall of the strut and toward the other flange wherein said inwardly depending flanges define an interior cavity with a cross-section having at its widest point a width greater than the width of the continuous slot of said strut.

Claim 7

An elongated strut having a generally flat back wall, side walls parallel to each other at least at the top section thereof, inturned lips from said side walls, and a continuous slot along the length of said strut between said lips, said elongated strut also having inwardly depending flanges disposed generally continuously along the length of said slot, said flanges formed to receive and secure fittings inserted into said slot and engaged with said flanges, whereby said fittings are removably secured by said flanges inside said strut and a first portion of each of said inwardly depending flanges projects generally toward the interior side wall of the strut adjacent to said flange and an end portion of each flange projects generally toward the interior back wall of the strut and toward the other flange wherein said inwardly depending flanges define an interior cavity with a cross-section having at its widest point a width greater than the width of the continuous slot of said strut.

Claim 8

The elongated strut of claim 5 wherein the upper portions of said inwardly depending flanges depend from the lips of said strut whereby opposing shelves are formed on the interior of the strut at the top thereof proximate the continuous slot of the strut.

Claim 9

The elongated strut of claim 5 or 6 wherein the distance between the ends of said flanges is smaller than the width of the continuous slot of the strut.

Claim 10

The elongated strut of claim 7 wherein said strut and said inwardly depending flanges are formed from a continuous piece of material.

Claim 11

An elongated strut having parallel side walls, a generally flat back wall and a pair of opposing flanges depending inwardly from the lips of said strut along the length of the continuous slot of said strut wherein the upper portions of said flanges are disposed in the interior of the strut below the top surface of the lips of the strut, and the end portions of said flanges are angled away from the side walls of the strut toward each other and toward the back wall of the strut whereby said inwardly depending flanges define an interior cavity with a cross-section having at its widest point a width greater than the width of the continuous slot of said strut, said inwardly depending flanges having a configuration to removably secure a generally rectangular member.

Claim 12

An elongated strut having parallel side walls, a generally flat back wall and a pair of opposing flanges depending inwardly from the lips of said strut along the length of the continuous slot of said strut wherein the upper portions of said flanges are disposed in the interior of the strut below the top surface of the lips of the strut, and the end portions of said flanges are angled away from the side walls of the strut toward each other and toward the back wall of the strut whereby said inwardly depending flanges define an interior cavity with a cross-section having at its widest point a width greater than the width of the continuous slot of said strut, said inwardly depending flanges having a configuration to removably secure a generally rectangular member.

Claim 13

The elongated strut of claim 5 or 9 wherein the end portions of said flanges removably engage the threaded portion of a fastener inserted therebetween and secure said fastener in a selected position anywhere along the slot of said strut.

Claim 14

The elongated strut of claim 7, 9 or 10 having removable alignment means disposed within the interior cavity defined by the flanges.

Claim 15

The elongated strut of claim 11 wherein said alignment means comprises an insert made from compressible material and formed to fill at least a portion of the interior cavity defined by the flanges and having a groove disposed beneath the continuous slot of said strut for receiving and securing fittings.
