Abstract
A supporting structure for vehicles that have an expandable room. Telescoping double tube extension beams are secured to the vehicle structure and combined with hydraulic extension cylinders to move the extendable room from the retracted to the extended position and back again. The inner tube of each extension beam is connected to the outer wall of the extendable room using a pivot connector that includes a mounting plate which has extending from it spaced apart support plates that provide bearing surfaces to support a journal. The journal has a transverse opening extending through it between the support plates, and a connecting member is used to attach the inner tube to the journal and therefore to the room mounting plate.
