DETAILED DESCRIPTION The following description of the preferred embodiment is merely exemplary in nature and is in no way intended to limit the disclosure, its application, or uses. With reference to FIG. 1 , a pickup truck 100 is shown having a foldable tonneau system 101 for use with pickup truck 100 . Pickup truck 100 generally includes a cargo box 102 and a passenger cabin 104 . Cargo box 102 includes a front wall (not shown), a left sidewall 108 , a right sidewall 110 , and a rear wall or tailgate 112 . It should be understood that right sidewall 110 and left sidewall 108 of pickup truck 100 are identical, yet arranged in mirrored symmetry. Accordingly, in the interest of brevity, only one side will be discussed in detail herein in connection with foldable tonneau system 101 unless noted otherwise. With further reference to FIGS. 2-4 , foldable tonneau system 101 includes a plurality of tonneau sections 116 . It should be understood that the principles of the present disclosure are equally applicable to foldable tonneau systems having two, three, or more sections, each foldable relative to adjacent sections. However, for purposes of this disclosure, a foldable tonneau system having three tonneau sections 116 a , 116 b , and 116 c will be described. This configuration should not be regarded as limiting the claims herein. Tonneau sections 116 a - 116 c may be individually referred to herein as front tonneau section 116 a , middle tonneau section 116 b , and rear tonneau section 116 c , and may be collectively referred to as tonneau sections 116 . Tonneau sections 116 each include a main body 120 . These components of tonneau sections 116 may be individually referred to as front main body 120 a , middle main body 120 b , and rear main body 120 c , and may be collectively referred to as main bodies 120 . Main bodies 120 will be described in further detail herein. Foldable tonneau system 101 further includes a frame assembly 122 . Frame assembly 122 covers the perimeter of foldable tonneau system 101 and is described in further detail herein. Foldable tonneau system also includes a plurality of sealing components 124 ( FIGS. 2-5 ). Sealing components 124 can be provided in a variety of positions around the perimeter of the bottom side of foldable tonneau system 101 to inhibit fluid communication between foldable tonneau system 101 and pickup truck 100 . FIGS. 1-4 illustrate foldable tonneau system 101 in an unfolded or extended configuration. Referring to FIG. 5 , a folded configuration of foldable tonneau system 101 is illustrated. Foldable tonneau system can include spacers 126 to provide support in a folded configuration. The installation of foldable tonneau system 101 on pickup truck 100 and the operation of foldable tonneau system 101 between the unfolded and folded configuration are described in further detail herein. Hinge Assemblies Tonneau sections 116 can be pivotably coupled to one another by hinge assemblies 140 ( FIGS. 1-5 ). In particular, front tonneau section 116 a and middle tonneau section 116 b can be pivotably coupled by a first hinge assembly 140 e , and middle tonneau section 116 b and rear tonneau section 116 c can be pivotably coupled by a second hinge assembly 140 f . With reference to FIGS. 6-9 , hinge assemblies 140 are illustrated in detail. It should be understood that first and second hinge assemblies 140 e , 140 f are substantially similar to each other. Accordingly, in the interest of brevity, only one of hinge assemblies 140 e , 140 f will be discussed in detail in connection with foldable tonneau system 101 unless noted otherwise. Additionally, it should be understood that hinge assemblies 140 e , 140 f and the components thereof can be collectively described (e.g., as “hinge assemblies 140 ”). With particular reference to FIG. 6 , first hinge assembly 140 e is shown in an unfolded or extended configuration, which corresponds to the unfolded configuration of foldable tonneau system 101 ( FIGS. 1-4 ). First hinge assembly 140 e includes a base component or base 150 e and a pair of pivot members 152 e pivotably coupled on opposing sides of base 150 e . Base 150 e includes a top wall 160 e and a bottom wall 162 e disposed substantially parallel to top wall 160 e . The top wall 160 e is wider than bottom wall 162 e and bottom wall 162 e is disposed so as to be centered relative to top wall 160 e . Base 150 e further includes a pair of sidewalls 164 e extending between top wall 160 e and bottom wall 162 e proximate the ends of bottom wall 162 e . Sidewalls 164 e include flat portions 166 e proximate bottom wall 162 e and curved portions 168 e between flat portions 166 e and top wall 160 e . Base 150 e further includes arcuate projections 170 e extending from top wall 160 e outside of sidewalls 164 e and proximate curved portions 168 e . Together, curved portions 168 e and projections 170 e define channels 172 e for receiving a portion of pivot members 152 e , as is described in further detail herein. Base 150 e further includes a pair of opposing edges 179 e of top wall 160 e each having a concave portion 180 e formed therein. Base 150 e further includes first sealing members 182 e disposed in concave portions 180 e . As is described in further detail herein, when first hinge assembly 140 e is in the extended configuration, first sealing members 182 e and pivot members 152 e engage and fluid communication therebetween is inhibited. Additionally, base 150 e includes boss portions 190 e . Boss portions 190 e are disposed on inside surfaces of sidewalls 164 e . As described in further detail herein, boss portions 190 e are configured to receive a fastener therein for securing an end cap to first hinge assembly 140 e. With reference to FIG. 7 , second hinge assembly 140 f is illustrated in an unfolded or extended configuration. Second hinge assembly 140 f is substantially similar to first hinge assembly 140 e . However, base 150 f is narrower than base 150 e , such that pivot members 152 f are less spaced apart than pivot members 152 e when first hinge assembly 140 e is in the extended configuration ( FIG. 6 ). As shown in FIG. 5 , the first hinge assembly 140 e is wider so that rear tonneau section 116 c can be sandwiched between front tonneau section 116 a and middle tonneau section 116 b when foldable tonneau system 101 is in the folded configuration. Additionally, base 150 f includes only a single boss portion 190 f . Boss portion 190 f extends between the inner surfaces of both of sidewalls 164 f. With reference to FIG. 8 , an exemplary pivot member 152 will be described in detail. In this exemplary embodiment of foldable tonneau system 101 , all of pivot members 152 are the same. As such, it is to be understood that this description applies to each of pivot members 152 e , 152 f described above with reference to hinge assemblies 140 e , 140 f. Pivot member 152 includes a short sidewall 200 , a tall sidewall 202 , and a bottom wall extending between short sidewall 200 and tall sidewall 202 . A cylindrical portion 210 is disposed on an end of the short sidewall 200 opposite bottom wall 204 . As shown in FIGS. 6-7 , cylindrical portion 210 is configured to be received by channels 172 and rotate therein. Pivot member 152 can further include a cover 212 over cylindrical portion 210 . Cover 212 has an inner surface 214 and projections 216 extending therefrom. Complementary to cover 212 , cylindrical portion 210 has an outer surface 218 with grooves 220 defined therein. Projections 216 are positioned on inner surface 214 of cover 212 to correspond with the positioning of grooves 220 on outer surface 218 of cylindrical portion 210 . Furthermore, projections 216 are received by grooves 220 to secure or otherwise inhibit relative rotation of cylindrical portion 210 and cover 212 . Therefore, cover 212 rotates with cylindrical portion 210 relative to each of channels 172 . Bases 150 and pivot members 152 can each be made of a variety of rigid materials including metals such as aluminum, and bases 150 and pivot members 152 can be the same material. Covers 212 can also be made of a variety of materials and can be a different material than bases 150 and pivot members 152 . For example, cover 212 can be made of a material such as plastic. As such, covers 212 can be configured so as to reduce friction between pivot members 152 and bases 150 . With continued reference to FIG. 8 , pivot member 152 further includes an outwardly facing concave portion 230 in short sidewall 200 proximate bottom wall 204 . Outwardly facing concave portion 230 can be configured to support a second sealing member 232 . As shown in FIGS. 6-7 , when hinge assemblies 140 e , 140 f are in extended configurations, second sealing members 232 can engage the outside surface of sidewalls 164 to seal or otherwise inhibit fluid communication therebetween. Pivot member 152 further includes a top L-shaped projection 240 and a bottom L-shaped projection 242 extending from opposite ends of tall sidewall 202 away from bottom wall 204 and short sidewall 200 . Top L-shaped projection 240 and bottom L-shaped projection 242 are oriented to face each other. Together, projections 240 , 242 and tall sidewall 202 define a coupling channel 244 . As described in further detail herein, coupling channels 244 are configured to engage and support components of frame assembly 122 of foldable tonneau system 101 . Pivot member 152 further includes a flange 249 extending from tall sidewall 202 opposite top L-shaped projection 240 . Flange 249 includes an upwardly facing concave feature 250 formed therein, a sloped projection 252 extending towards cylindrical portion 210 , and a flat projection 254 extending away from sloped projection 252 . As illustrated in FIGS. 6-7 , sloped projections 252 are configured to engage first sealing members 182 of bases 150 when hinge assemblies 140 are in the unfolded configurations. Pivot member 152 also includes a downwardly facing concave feature 260 formed between bottom wall 204 and tall sidewall 202 . As is described in more detail herein, concave feature 250 , flat projection 254 , and concave feature 260 are configured to aid the assembly of foldable tonneau system 101 . As described above, with reference to FIGS. 6-7 , when hinge assemblies 140 are in the extended configurations, short sidewalls 200 of pivot members 152 extend substantially parallel to flat portions 166 of bases 150 . Furthermore, sloped portions 252 of pivot members 152 engage sealing members 182 of bases 150 , and sealing members 232 of pivot members 152 engage flat portions 166 of bases 150 . As such, fluid communication is prevented between bases 150 and pivot members 152 . With further reference to FIGS. 1-3 , top walls 160 of bases 150 define a portion of the top of surface of foldable tonneau system 101 . Therefore, the engagement of sealing members 182 and sloped projections 252 is a primary seal between foldable tonneau system 101 and the environment outside of pickup truck 100 . It is possible that water or other fluid could bypass this primary seal during operation of foldable tonneau system 101 or due to a failure in the sealed engagement. However, pivot members 152 are configured such that an inside surface 264 of short sidewall 200 , an inside surface 266 of tall sidewall 202 , and an inside surface 268 of bottom wall 204 combine to define a gutter 270 along hinge assemblies 140 across pickup truck 100 . Any fluid which bypasses the primary seal between sealing members 182 and sloped projections 252 will be collected in gutters 270 . Furthermore, pivoting members 152 are configured to span across the entire width of cargo box 102 of pickup truck 100 . Therefore, fluid can run out the sides of gutters 270 and outside of cargo box 102 . Additionally, the engagement between second sealing members 232 and sidewalls 164 provide a secondary seal in hinge assemblies 140 . When foldable tonneau system 101 is in the folded configuration ( FIG. 5 ), both of hinge assemblies 140 e , 140 f are in corresponding folded configurations. With reference to FIG. 9 , second hinge assembly 140 f is shown in detail in the folded configuration. In particular, FIG. 9 illustrates that pivoting members 152 f can rotate approximately 90° relative to base 150 f from the unfolded configuration of FIG. 7 . For example, in the folded configuration, short sidewalls 200 f are oriented substantially perpendicular to flat portions 166 f of base 150 f . Furthermore, inside surfaces 264 f of short sidewalls 200 f are engaged with ends of projections 170 f of base 150 f . This engagement prevents pivot members 152 f from being oriented such that tonneau sections 116 b and 116 c would contact one another. As shown in FIGS. 5 and 9 , tonneau sections 116 b and 116 c extend parallel to each other in this folded configuration. It is to be understood that this description equally applies to the folded configuration of first hinge assembly 140 e. Main Bodies Referring again to FIGS. 1-5 , each of tonneau sections 116 includes one of main bodies 120 . With further reference to FIG. 10 , an exemplary portion of one of main bodies 120 is illustrated. Each of main bodies 120 includes a top sheet 330 , a bottom sheet 332 , and a core 334 sandwiched therebetween. Top sheet 330 , bottom sheet 332 , and core 334 can be made of relatively rigid materials such as aluminum. Core 334 can have, e.g., a honeycomb design to provide rigidity and strength while limiting weight. The components of main bodies 120 can be fixed together, e.g., by an adhesive material such as glue. For example, glue can be applied between top and bottom sheets 330 , 332 and core 334 . With core 334 having, e.g., a honeycomb design, excess glue can be displaced to gaps in core 334 . Therefore, top and bottom sheets 330 , 332 can each have consistent interfaces with core 334 such that top and bottom sheet 330 , 332 can define smooth outer surfaces. Components of main bodies 120 can also be fixed to hinge assemblies 140 , e.g., by an adhesive material such as glue. For example, as shown in FIG. 8 , top sheet 330 can extend over a top surface of top L-shaped projection 240 and under flat projection 254 of pivot member 152 . Glue can be applied between top sheet 330 and the top surface of top L-shaped projection 240 , and excess glue can be displaced into concave feature 250 . Similarly, glue can be applied between bottom sheet 332 and a bottom surface of bottom L-shaped projection 242 , and excess glue can be displaced into concave feature 260 . Therefore, as concave features 250 , 260 wick away excess glue from the interfaces of top and bottom sheets 330 , 332 and pivot member 152 , top and bottom sheets 330 , 332 can each have consistent interfaces with pivot member 152 such that top and bottom sheets 330 , 332 can define smooth outer surfaces. As illustrated in FIGS. 2-4 , front main body 120 a of front tonneau section 116 a includes a bow member 340 a disposed therein, and rear main body 120 c of rear tonneau section 116 c includes a bow member 340 c disposed therein. Bow members 340 a , 340 c are disposed within main bodies 120 a , 120 c in gaps defined bottom sheets 332 a , 332 c and cores 334 a , 334 c , respectively, of tonneau sections 116 a , 116 c . Bow members 340 are configured to house latching assemblies for removably securing foldable tonneau system 101 to pickup truck 100 . With reference to FIG. 11 , an exemplary one of bow members 340 is illustrated in detail. It should be understood that the following description equally applies to each of bow members 340 , including bow members 340 a , 340 c described above. Bow member 340 has a concave shape and includes a top surface 342 with side surfaces 343 extending away from edges of top surface 342 . Bow member 340 further includes ribs 344 extending from top surface 342 opposite side surfaces 343 . Ribs 344 are spaced apart on top surface 342 so as to define gaps 346 adjacent thereto. Furthermore, an adhesive material such as glue can also be applied between top sheet 330 and bow member 340 . For example, glue can be applied on ribs 344 of bow member 340 , and excess glue can be displaced into gaps 346 adjacent to ribs 344 . Therefore, top sheet 330 can have a consistent interface with bow member 340 such that top sheet 330 can define a smooth outer surface. Frame Assembly Referring again to FIG. 1 , foldable tonneau system 101 includes frame assembly 122 . Frame assembly 122 includes a plurality of side frame members 362 . Side frame members 362 extend along the sides of tonneau sections 116 that are not coupled to one of hinge assemblies 140 . As such, front tonneau section 116 a and rear tonneau section 116 c have three side frame members 362 attached thereto, and middle tonneau section 116 b has two side frame members 362 attached thereto. With reference to FIG. 12 , an exemplary side frame member 362 is illustrated. Similar to pivot members 152 , side frame members 362 include a coupling channel 364 configured to engage with other frame components, upwardly facing concave features 366 , and downwardly facing concave features 368 . Similar to the corresponding features of pivot members 152 , concave features 366 , 368 of side frame members 362 are configured to aid the assembly of foldable tonneau system 101 . For example, frame assembly 122 and main bodies 120 can be fixed together, e.g., by an adhesive material such as glue. Top and bottom sheets 330 , 332 of main bodies 120 can extend over side top and bottom surfaces of side frame members 362 , and concave features 366 , 368 can function to wick away excess glue from the interfaces of top and bottom sheets 330 , 332 and side frame members 362 , as is described above with regard to pivot members 152 and concave features 250 , 260 . Therefore, top and bottom sheets 330 , 332 can each have consistent interfaces with side frame members 362 such that top and bottom sheets 330 , 332 can define smooth outer surfaces. Frame assembly 122 can further include end caps disposed on the ends of hinge assemblies 140 . With reference to FIGS. 13A-13B , an exemplary end cap 370 e is illustrated. End cap 370 e is configured to be fixed at the end of first hinge assembly 140 e and includes holes 372 e formed therein to receive fasteners (not shown) for attaching end cap 370 e to first hinge assembly 140 e . Holes 372 e are configured to align with bosses 190 e of first hinge assembly 140 e . The fasteners can extend through holes 372 e and threadingly engage bosses 190 e to secure end cap 370 e and first hinge assembly 140 e. With reference to FIGS. 14A-14B , an exemplary end cap 370 f is illustrated. End cap 370 f is configured to be fixed at the end of second hinge assembly 140 f and includes a single hole 372 f that corresponds with the single boss 190 f of second hinge assembly 140 f . As such, a single fastener (not shown) can secure end cap 370 f and second hinge assembly 140 f . A projection 373 f in end cap 370 f projects outward to engage a similarly shaped hollow 375 f in base 150 f ( FIG. 7 ). This engagement prevents end cap 370 f from rotating and allows use of only one fastener. The position of end caps 370 when attached to hinge assemblies 140 is illustrated in FIGS. 5 and 9 . With reference to FIGS. 15-17 , frame assembly 122 further includes corner components 392 , 394 , 396 . Corner components 392 and 394 can be disposed between one of side members 362 and one of pivoting members 152 . For example, side portions 398 , 399 of corner components 392 , 394 are curved to correspond with a side of one of end caps 370 . Furthermore, first ends 400 , 402 of corner components 392 , 394 can engage coupling channels 244 of pivot members 152 of hinge assemblies 140 so as to secure each of corner components 392 , 394 to one of pivot members 152 . Second ends 404 , 406 of corner components 392 , 394 can engage coupling channels 364 of side frame members 362 so as to secure each of corner components 392 , 394 to one of side frame members 362 . Corner component 396 can be disposed between two of side members 362 . For example, each of first and second ends 408 , 410 of corner component 396 can engage one of coupling channels 364 of side frame members 362 so as to secure corner component 396 to side frame members 362 . Installation The installation of foldable tonneau system 101 on cargo box 102 of pickup truck 100 will now be described. A foldable tonneau system 101 in the folded configuration is first placed upon sidewalls 108 , 110 of cargo box 102 such that side members 362 of front tonneau section 116 a are equally positioned upon a top surface of sidewalls 108 , 110 . Foldable tonneau system can include one or more restraining assemblies 420 ( FIGS. 2 , 3 , and 5 ) which can be selectively operated to maintain foldable tonneau system 101 in the folded configuration. Therefore, to extend foldable tonneau system 101 , restraining assemblies 420 are unlatched to permit the bundled group of middle tonneau section 116 b and rear tonneau section 116 c to be pivoted about first hinge assembly 140 e relative to front tonneau section 116 a . Foldable tonneau system 101 is then adjusted to ensure proper positioning of foldable tonneau system 101 on cargo box 102 . Front latch assemblies are them slid to outboard positions adjacent a flange of sidewalls 108 , 110 by sliding along cross bow member 340 a to engage the flange of sidewalls 108 , 110 and, thereby, to affect a reliable coupling. Rear tonneau section 116 c is then pivoted about second hinge assembly 140 f relative to middle tonneau section 116 b to conceal cargo box 102 . Rear latch assemblies are then slid to outboard positions adjacent the flange of sidewalls 108 , 110 by sliding along cross bow member 340 c and positioned to engage the flange of sidewalls 108 , 110 and, thereby, to affect a reliable coupling. To fold foldable tonneau system 101 , the rear latch assemblies are disengaged from sidewalls 108 , 110 and slid inboard by sliding along cross bow member 340 c . Rear tonneau section 116 c can be pivoted about second hinge assembly 140 f to the folded configuration. Furthermore, the bundled group of rear tonneau section 116 c and middle tonneau section 116 b can be pivoted about first hinge assembly 140 e such that foldable tonneau system 101 is in the folded configuration ( FIG. 5 ). Finally, restraining assemblies 420 can be engaged to serve foldable tonneau system 101 in the folded configuration. The present disclosure is exemplary and, therefore, can vary in many ways. A foldable tonneau system according to the present disclosure can actually have a variety of members of sections. Furthermore, the sections can include a variety of components and configurations. The components described herein can be made from a variety of materials and can have a variety of configurations. Additionally, the components and sections described herein can be assembled together in a variety of ways.
