DETAILED DESCRIPTION OF THE ILLUSTRATED EMBODIMENTS

(6) This disclosure is susceptible of embodiment in many different forms. There are shown in the drawings and will herein be described in detail representative embodiments of the disclosure with the understanding that the present disclosure is to be considered as an exemplification of the principles of the disclosure and is not intended to limit the broad aspects of the disclosure to the embodiments illustrated. To that extent, elements and limitations that are disclosed, for example, in the Abstract, Summary, and Detailed Description sections, but not explicitly set forth in the claims, should not be incorporated into the claims, singly or collectively, by implication, inference or otherwise. For purposes of the present detailed description, unless specifically disclaimed: the singular includes the plural and vice versa; the words and and or shall be both conjunctive and disjunctive; the word all means any and all; the word any means any and all; and the words including and comprising and having mean including without limitation. Moreover, words of approximation, such as about, almost, substantially, approximately, and the like, can be used herein in the sense of at, near, or nearly at, or within 3-5% of, or within acceptable manufacturing tolerances, or any logical combination thereof, for example.

(7) Referring now to the drawings, wherein like reference numbers refer to like features throughout the several views, there is shown in FIG. 1 a representative automobile, which is portrayed as a two-door pickup truck and designated generally at 10, and illustrated in accordance with aspects of the present disclosure. Mounted at a rearward portion of the automobile 10, e.g., aft of a passenger compartment 14 and forward of a tailgate 16, is an expandable tonneau cover assembly 12 that extends over a cargo bed 18 (FIG. 1A) of a rear cargo compartment 20. The illustrated automobile 10also referred to herein as motor vehicle or vehicle for shortis merely an exemplary application with which the novel aspects of this disclosure can be practiced. In the same vein, the implementation of the present concepts into an open-bed cargo compartment should also be appreciated as an exemplary application of the novel concepts disclosed herein. As such, it will be understood that the aspects and features of the present disclosure can be integrated into other types of vehicle cargo compartments and utilized for any type of motor vehicle. Lastly, the drawings presented herein are not necessarily to scale and are provided purely for instructional purposes. Thus, the specific and relative dimensions shown in the drawings are not to be construed as limiting.

(8) There is shown throughout the Figures a representative expandable tonneau cover 12 (also referred to herein as expandable cover assembly) that spans the upper extent of the cargo compartment 20 for concealing and protecting the contents thereof. Opposing left and right cargo compartment sidewalls 28 and 30, respectively, adjoin with left and right lateral edges of the cargo bed 18; the tonneau cover 12 is removably connected to and extends between the cargo bed's 18 sidewalls 28 and 30, from a forward endwall 32 to the rear tailgate 16. It should be recognized that the tonneau cover 12 can take on alternative sizes and placements from that which is shown in the drawings depending, for example, on the intended application of the assembly. In one instance, the tonneau cover 12 can be reconfigured as a three-quarter length or a partial-width toolbox tonneau that extends across some, but not all, of the cargo compartment 20. According to the illustrated example, the expandable cover assembly 12 is fabricated as a tripartite construction composed of three principal components: a frame section 22, an erectable canopy 24, and a peripherally continuous gusset 26 that functions as a flexible joint for movably connecting the canopy 24 to the frame 22. Alternative configurations, however, may be fabricated from more than three primary segments or constructed as bipartite or single-piece constructions, e.g., where one or more or all of the aforementioned constituent parts are integrally formed as a one-piece component.

(9) To secure the expandable cover assembly 12 to the vehicle 10, opposing lateral sides 21 and 23 of the frame section 22 can be provided with attachment features 34 (e.g., grommet-sealed bolt holes or riveted male snap fasteners) that removably couple to mating structure 36 (e.g., threaded bolt slots or mating female snap fasteners on complementary cover rails) of the cargo bed's 18 lateral sidewalls 28, 30. Optional peripheral hardware, such as weather-tight seal strips, cover rail mounting clamps/brackets, vibration-damping shims, tension-adjusting worm screws, and storage straps, while not shown can certainly be included with the cover assembly 12. Alternative means for securing the expandable cover assembly 12 to the vehicle 10, including manual and automated systems, are within the scope of the present disclosure. This may include pivot hinges, pneumatic cylinders or mounting brackets (not shown) at a forward longitudinal side 25 of the frame section 22 for coupling the cover assembly 12 to the cargo compartment's 20 forward endwall 32, and/or a tailgate bar (not shown) at the frame's 22 a rearward longitudinal side 27 for coupling to the tailgate 18.

(10) In addition to securely attaching the expandable cover assembly 12 to the truck bed, the frame section 22 can also operate to provide functional support for the canopy 24. With collective reference to FIGS. 1 and 1A, the frame's 22 lateral sides 21, 23 are integrally formed with or otherwise attached to the opposing longitudinal sides 25, 27 to define a framework with a central aperture 38 within which is seated the canopy 24. The frame section 22, canopy 24 and central aperture 38 can be fabricated with complementary (square or rectangular) shapes such that the frame section 22 extends continuously around and circumscribes the canopy 24 with the outer perimeter of the canopy 24 coterminous with the inner periphery of the aperture 38. As shown, the frame 22, canopy 24, and aperture 38 all have generally closed polygonal shapes with the central aperture 38 extending through the center of the frame section 22. It is envisioned that the foregoing features of the tonneau cover assembly 12, individually or collectively, can take on any combination of alternative shapes. Moreover, the aperture 38 can be repositioned to any location of the frame section 22, including one or more edges of the frame 22 such that the aperture 38 has a discontinuous perimeter. When the canopy 24 is seated in or above the central aperture 38, the frame section 22 and canopy 24 extend across the entire rear cargo compartment 20, as seen in FIGS. 1 and 2.

(11) A flexible joint, represented herein by a bendable gusset 26, attaches the canopy 24 to the frame section 22 such that the canopy 24 can be raised and lowered to accommodate objects, such as cargo box CG1 of FIG. 2A, of differing shapes, dimensions and volumes. According to the illustrated example, the gusset 26 is fabricated with a square annular shape from a flexible fabric material that extends continuously around the outer perimeter of the canopy 24. Discontinuous designs may comprise a segmented gusset with sections incorporated at only desired locations along the perimeter of the canopy (e.g., along only the lateral or the longitudinal sides). It may be desirable, for at least some embodiments, to construct the frame 22, canopy 24 and gusset 26 from the same material, which may be in the nature of a water resistant/proof, flame retardant, UV reflective, and/or tear-resistant coated polyester or vinyl material. Alternative designs can incorporate a frame and/or canopy that are fabricated from more rigid materials, such as fiberglass, aluminum or plastic (ABS) paneling.

(12) Referring to both FIGS. 1A and 2A, the expandable tonneau cover assembly 12 can be selectively positioned in a collapsed state, which is portrayed in FIG. 1A, and subsequently or thereafter selectively raised to an expanded state, which is illustrated in FIG. 2A. When the assembly 12 is manually or electronically placed in the collapsed state (FIGS. 1 and 1A), the canopy 24 is positioned at a first height H1 from the cargo bed 18 floor of the cargo compartment 20. Conversely, when the assembly 12 is manually or electronically placed in the expanded state (FIGS. 2 and 2A), the canopy 24 is positioned at a second height H2 from the cargo bed 18 floor, which is higher than the first height H1. Collapsing the tonneau cover assembly 12 places the uppermost (canopy) surface of the canopy 24 generally parallel to and substantially flush with the uppermost (frame) surface of the frame section 22, as seen in FIG. 1A. Concomitantly, the flexible gusset 26 is lowered, e.g., in a telescoping manner, into the interior storage volume of the cargo compartment 20. To secure the canopy 24 in the collapsed state, a mechanical fastener 40, which may be in the nature of a zipper or a hook-and-loop flap, rigidly attaches the outer perimeter of the canopy 24 to the inner periphery of the frame's 22 central aperture 38. While the mechanical fastener 40 is shown extending continuously around the outer perimeter of the canopy 24 in the illustrated example, alternative variations may comprise a fastener or fasteners located at only select locations of the frame 22 and canopy 24. On the other hand, expanding the tonneau cover 12 places the uppermost (canopy) surface of the canopy 24 above the uppermost (frame) surface of the frame section 22, as seen in FIG. 2A. At the same time, the flexible gusset 26 is raised out of the interior storage volume of the cargo compartment 20 and contemporaneously surrounds the object CG1. Optionally, an internally packaged articulating skeletal armature or a removable scaffolding/stanchion arrangement can be inserted underneath the canopy 24 to retain the assembly 12 in the raised position.

(13) While aspects of the present disclosure have been described in detail with reference to the illustrated embodiments, those skilled in the art will recognize that many changes may be made thereto without departing from the scope of the present disclosure. The present disclosure is not limited to the precise construction and compositions disclosed herein; any and all modifications, changes, and variations apparent from the foregoing descriptions are within the spirit and scope of the disclosure as defined in the appended claims. Moreover, the present concepts expressly include any and all combinations and subcombinations of the preceding elements and features.
