Abstract

A longitudinal length adjustable header made up of a center section and two end sections moveably attached to the center section. The center section has an “L” shaped cross section and at least two longitudinal slots that are adapted to receive bolt means there through. The end sections have a plurality of apertures that align with the slots in the center section and are adapted to receive bolt means there through. The end sections are longitudinally slidable with respect to the center section whereby enabling adjusting the length of the header.

Claims

1. A load bearing, structural header which is adjustable in length, which comprises:

a center section, the center section being generally “

L”

shaped in transverse cross section and including a first elongated leg and a second elongated leg joined perpendicularly to the first elongated leg, each of the first leg and the second leg having a thickness, the center section further having a first slot formed through the thickness of the first leg, and a second slot formed through the thickness of the first leg;

a first end section, the first end section including at least one elongated plate having a thickness, the at least one plate of the first section having a plurality of spaced apart apertures formed through the thickness thereof, the first end section being adjustably mounted on the center section in proximity to the first slot formed in the center section;

a second end section, the second end section including at least one elongated plate having a thickness, the at least one plate of the second section having a plurality of spaced apart apertures formed through the thickness thereof, the second end section being adjustably mounted on the center section in proximity to the second slot formed in the center section;

a first plurality of bolts, the first plurality of bolts being received by corresponding spaced apart apertures of the plurality of apertures formed through the thickness of the at least one plate of the first end section and further being received by the first slot of the center section;

a second plurality of bolts, the second plurality of bolts being received by corresponding spaced apart apertures of the plurality of apertures formed through the thickness of the at least one plate of the second end section and further being received by the second slot of the center section;

a first flange, the first flange being joined perpendicularly to the first end section; and

a second flange, the second flange being joined perpendicularly to the second end section.

2. The load bearing, structural header as defined by claim 1, which further comprises:

at least a first pointed protrusion joined to and extending outwardly from the first flange; and

at least a second pointed protrusion joined to and extending outwardly from the second flange.

3. A load bearing, structural header which is adjustable in length, which comprises:

a center section, the center section being generally “

L”

shaped in transverse cross section and including a first elongated leg and a second elongated leg joined perpendicularly to the first elongated leg, each of the first leg and the second leg having a thickness, the center section further having a first slot formed through the thickness of the first leg, and a second slot formed through the thickness of the first leg;

a first end section, the first end section including a first elongated plate and a second elongated plate, the second elongated plate of the first end section being spaced apart laterally from the first elongated plate of the first end section and extending in parallel with the first elongated plate of the first end section to define a space between the first elongated plate and the second elongated plate of the first end section, each of the first elongated plate and the second elongated plate of the first end section having a thickness, each of the first elongated plate and the second elongated plate of the first end section having a plurality of spaced apart apertures formed through the thickness thereof, the first end section being adjustably mounted on the center section in proximity to the first slot formed in the center section, the first elongated leg of the center section being received within the space defined between and by the first elongated plate and the second elongated plate of the first end section;

a second end section, the second end section including a first elongated plate and a second elongated plate, the second elongated plate of the second end section being spaced apart laterally from the first elongated plate of the second end section and extending in parallel with the first elongated plate of the second end section to define a space between the first elongated plate and the second elongated plate of the second end section, each of the first elongated plate and the second elongated plate of the second end section having a thickness, each of the first elongated plate and the second elongated plate of the second end section having a plurality of spaced apart apertures formed through the thickness thereof, the second end section being adjustably mounted on the center section in proximity to the second slot formed in the center section, the first elongated leg of the center section being received within the space defined between and by the first elongated plate and the second elongated plate of the second end section;

a first plurality of bolts, the first plurality of bolts being received by corresponding spaced apart apertures of the plurality of apertures formed through the thicknesses of the first elongated plate and the second elongated plate of the first end section and further being received by the first slot of the center section, whereby the first plurality of bolts pass through the thickness of the first elongated plate of the first end section, the thickness of the first leg of the center section and the thickness of the second elongated plate of the first end section;

a second plurality of bolts, the second plurality of bolts being received by corresponding spaced apart apertures of the plurality of apertures formed through the thicknesses of the first elongated plate and the second elongated plate of the second end section and further being received by the second slot of the center section, whereby the second plurality of bolts pass through the thickness of the first elongated plate of the second end section, the thickness of the first leg of the center section and the thickness of the second elongated plate of the second end section;

a first flange, the first flange being joined perpendicularly to the first end section; and

a second flange, the second flange being joined perpendicularly to the second end section.

4. The load bearing, structural header as defined by claim 3, which further comprises:

at least a first pointed protrusion joined to and extending outwardly from the first flange; and

at least a second pointed protrusion joined to and extending outwardly from the second flange.
