Cross-Struts for Beam Assemblies

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.

What is claimed is: 
     
         1 - 7 . 
     
     
         8 . An elevator assembly, comprising:
 at least three vertical beams arranged in a triangular configuration, each vertical beam having at least a first channel and a second channel;   three horizontal lifting beams, each having a first end coupled to a first channel of one of the vertical beams and a second end coupled to a second channel of an adjacent vertical beam;   an elevator cabin coupled to each of the horizontal lifting beams;   a motor; and   wherein a linear actuator is disposed inside the first channel and the second channel of each vertical beam, and synchronized to the motor to lift the elevator cabin.   
     
     
         9 . The assembly of  claim 8 , wherein the first end of each horizontal lifting beam is coupled to the first channel of one of the vertical beams via a carrier bracket, and the second end of each horizontal lifting beam is coupled to the second channel of an adjacent vertical beam via another carrier bracket. 
     
     
         10 . The assembly of  claim 9 , wherein the at least three vertical beams comprises three vertical beams arranged in a triangular configuration. 
     
     
         11 . The assembly of  claim 9 , wherein the at least three vertical beams comprises four vertical beams arranged in a triangular configuration. 
     
     
         12 . The assembly of  claim 9 , wherein the three horizontal lifting beams form a triangular lifting platform.
