Abstract
The present technology relates to beams having a cross section defining a plurality of channels and assemblies comprising the beams. The beams can be used to form a beam assembly that is installed inside the truck bed of a pick-up truck. A ladder loader and a solar panel assembly can be pivotably secured to the beam assembly along either the driver side wall or the passenger side wall of the truck bed.
Claims21
A beam, comprising:
- exactly three substantially rectangular channels that include a first channel, a second channel, and a third channel, wherein each channel is defined by:
- a back inner surface;
- two side inner surfaces, wherein the side inner surfaces face each other, and wherein the side inner surfaces extend from and are perpendicular to the back inner surface;
- and
- a front side comprising:
- two flanges each extending from an end of a different one of the two side inner surfaces, wherein the ends of the side inner surfaces are opposite the back inner surface, and wherein each flange comprises:
- a first portion extending perpendicularly from one of the two side inner surfaces and defining a first inner surface parallel to and facing the back inner surface;
- a second portion extending perpendicularly from the first portion and toward the back inner surface, wherein the second portion is planar and defines a side rolling surface, wherein the side rolling surfaces of each flange face each other and define an opening to the channel;
- and
- a third portion extending perpendicularly from the second portion and toward the side inner surface from which the first portion of the flange extends, wherein the third portion defines a third inner surface that is planar and is parallel to and faces the back inner surface;
- wherein the back inner surface of the first channel shares a first unitary, shared wall with a first of the side inner surfaces of the third channel;
- wherein the back inner surface of the second channel shares a second unitary, shared wall with a second of the side inner surfaces of the third channel;
- and
- wherein the third channel is positioned between the first channel and the second channel such that the opening of the third channel is perpendicular to the openings of the first and second channels.
