Abstract: A tonneau cover apparatus for removable attachment to a cargo box of a pickup truck including a support frame assembly and a cover assembly. The cover assembly includes a plurality of pivotally interconnected rigid panels that can be folded up and secured to the cargo box such that respective upper surfaces of at least two of the plurality of rigid panels reside in an upright folded orientation. The tonneau cover apparatus further includes a mechanism for securing the at least two of the plurality of rigid panels in the upright folded orientation. A method of removably securing the tonneau cover apparatus to the pickup truck is also described, as is an alternate embodiment of the tonneau cover apparatus, wherein the cover assembly includes first and second pivotally interconnected rigid panels and a pair of hinge support mechanisms that generally restrict the way the second rigid panel pivots.

Abstract: A folding tonneau cover apparatus including a cover assembly and a support frame assembly. The cover assembly having a plurality of rigid panels interconnected in series by a series of flexible hinges. Elongated support members having hinge support flanges help to secure the flexible hinges to the rigid panels. In preferred embodiments, the support flanges of the elongated support members cooperate with the underside of the respective rigid panels to which the support members are secured, to form a partial enclosure within which a side portion of the respective flexible hinge is secured. The cover assembly is secured to the support frame assembly to cover a cargo box of a pickup truck by a plurality of locking members when the support frame assembly is secured to sidewalls of the cargo box. Methods of making a tonneau cover apparatus and methods of folding and unfolding the cover assembly are also disclosed.
