Alternatively, suitable materials can be used and sections or elements made independently and attached or coupled together, such as by adhesives, welding, screws, rivets, pins, or other fasteners, to form the various elements of the rack system 500.
It should also be understood that the overall size and shape of the rack system 500, and the various portions thereof, is a design choice based upon the desired functionality and/or appearance of the rack system 500.
The rack system 500 also includes a set of support straps 700 that can be attached to the loops 240 to limit movement of the horizontal and vertical frames when attached to the vehicle. A hitch connection is provided at the lower end of the lower base unit 100. The lower base unit 100 serves as the vertical support frame for the upper base unit 200. The upper base unit 200 is cantilevered over the vehicle 800 to provide an elevated rack system above the roof of the vehicle 800.
During installation and use, as illustrated most clearly in FIGS. 23-29, the lower base unit 100 is assembled. First, the center-post adjustment sleeve assembly 300 is slid over the hitch beam vertical support 120 so that the handle 340 faces rearward (the opposite side of where the lower base unit 100 is attached to the trailer hitch 810 of the vehicle 800). A hitch pin, such as, for example, a 5⁄8 inch diameter each pin, is temporarily placed within the hitch pin holder 118 of the lower base unit 100.
Next, the first end 112 of the hitch beam 100 and is inserted into the vehicle tow hitch receiver tube 810. The lower base unit 100 is urged forward into position so that the hitch beam vertical support 120 is in contact with the spare tire 820 (if included). Once positioned, the hitch pin hole of the tow hitch receiver tube 810 is aligned with the appropriate hitch beam aperture 116 and the hitch pin is removed from the hitch pin holder 118 and inserted through the trailer hitch 810 to secure the lower base unit 100 to the trailer hitch 810.
Next, the center-point adjustable sleeve assembly 300 is positioned about the hitch beam vertical support 120 and aligned with spare tire 820 in a manner that will facilitate the strap entry through the wheel of the spare tire 810. One or more pins or bolts 600 (such as, for example, to 3⁄8 inch diameter by 23⁄4 inch length bolts) are used to secure the center-point adjustable sleeve assembly 300 to the hitch beam vertical support 120, via alignment and interaction of the hitch beam vertical support apertures 126 and the sleeve element apertures 316.
Then, a cam strap (not shown) is inserted through an adjustment plate aperture 335 and the cam strap is pulled until the cam strap buckle pad prevents any further movement of the cam strap. The cam strap is then inserted through a first opening in the wheel of the spare tire 820 and back out through a second opening in the wheel of the spare tire 820 and through the adjustment plate aperture 335. The cam strap is then positioned through the cam strap buckle and pulled tight.
