1. A foldable clipboard, comprising:
at least a first folding panel, a second folding panel, a third folding panel, and a fourth folding panel, each folding panel configured to cooperate to form a single planar surface when positioned in an expanded position, such that a second edge of the first folding panel abuts a first edge of the second panel, a second edge of the second panel abuts a first edge of the third folding panel, and a second edge of the third folding panel abuts a first edge of the fourth folding panel;
a first pair of hinges, each hinge of the first pair of hinges positioned spaced-apart in a transverse alignment relative to each other, each hinge of the first pair of hinges including an outer leg bracket and an inner leg bracket that are pivotally connected together, wherein each respective outer leg bracket of the first pair of hinges connects to one of the first side edge and the second side edge, respectively, of the first folding panel and each respective inner leg bracket of the first pair of hinges connects to one of the first side edge and the second side edge, respectively, of the second folding panel;
a second pair of hinges, each hinge of the second pair of hinges positioned spaced-apart in a transverse alignment relative to each other, each hinge of the second pair of hinges including an outer leg bracket and an inner leg bracket that are pivotally connected together, wherein each respective outer leg bracket of the second pair of hinges connects to one of the first side edge and the second side edge, respectively, of the second folding panel and each respective inner leg bracket of the second pair of hinges connects to one of the first side edge and the second side edge, respectively, of the third folding panel;
a third pair of hinges, each hinge of the third pair of hinges positioned spaced-apart in a transverse alignment relative to each other, each hinge of the third pair of hinges including an outer leg bracket and an inner leg bracket that are pivotally connected together, wherein each respective outer leg bracket of the third pair of hinges connects to one of the first side edge and the second side edge, respectively, of the third folding panel and each respective inner leg bracket of the third pair of hinges connects to one of the first side edge and the second side edge, respectively, of the fourth folding panel;
wherein each outer leg bracket and each inner leg bracket of the first pair of hinges, the second pair of hinges, and the third pair of hinges includes an inner side, and an outer side, the inner sides of the outer leg brackets of the first pair of hinges facing each other and each facing a respective one of the outer sides of the inner leg brackets of the first pair of hinges, the inner sides of the outer leg brackets of the second pair of hinges facing each other and each facing a respective one of the outer sides of the inner leg brackets of the second pair of hinges, the inner sides of the outer leg brackets of the third pair of hinges facing each other and each facing a respective one of the outer sides of the inner leg brackets of the third pair of hinges,
wherein when the foldable clipboard is moved into a folded position, as to each hinge in the first pair of hinges, the inner side of the outer bracket of the hinge pivotally moves over the outer side of the inner bracket of the hinge such that the outer bracket overlaps the inner bracket, and as to each hinge in the second pair of hinges, the inner side of the outer bracket of the hinge pivotally moves over the outer side of the inner bracket of the hinge such that the outer bracket overlaps the inner bracket, and as to each hinge in the third pair of hinges, the inner side of the outer bracket of the hinge pivotally moves over the outer side of the inner bracket of the hinge such that the outer bracket overlaps the inner bracket, and wherein each of the outer brackets is visibly in front of a respective cooperating one of the inner brackets when the clipboard is in a folded position.
