a second structure; and a double jointed hinge that connects the first structure and the second structure, the double jointed hinge comprising: a first hinge element that defines a first axis of rotation, and the first hinge element is connected to the first structure; a second hinge element that defines a second axis of rotation and is connected to the second structure, and the second hinge element is spaced apart from the first hinge element; and a first link and a second link, the first link and the second link connecting the first hinge element to the second hinge element, wherein the first link and the second link are rotatable about the first hinge element so as to enable movement of the second hinge element relative to the first hinge element, and wherein the first hinge element extends through the first link and through the second link, and the second hinge element does not extend through the first link or through the second link. ### Claim 9 (depends on 8) The assembly as recited in claim 8, wherein the first structure is a wall and the second structure is a door. ### Claim 10 (depends on 8) The assembly as recited in claim 8, wherein the second structure is rotatable about 180 degrees relative to the first structure. ### Claim 11 (depends on 8) The assembly as recited in claim 8, wherein the second structure is rotatable about 180 degrees relative to the first hinge element and about 90 degrees relative to the second hinge element. ### Claim 12 (depends on 8) The assembly as recited in claim 8, wherein the second hinge element is movable relative to the first hinge element. ### Claim 13 (depends on 8) The assembly as recited in claim 8, wherein the second hinge element is rotatable about the first hinge element. ### Claim 14 A portion of a shed, comprising: a blow molded plastic door; a blow molded plastic wall panel; and a double jointed hinge configured to connect the blow molded plastic door and the blow molded plastic wall panel to each other, the double jointed hinge comprising: a first hinge element that connectible to the blow molded plastic wall panel; a second hinge element that is connectible to the blow molded plastic door; and a first link and a second link, the first link and the second link configured to connect the first hinge element to the second hinge element so that the second hinge element is spaced apart from the first element, and wherein when so connected, the first hinge element extends through the first link and through the second link, and the second hinge element does not extend through the first link or through the second link. ### Claim 15 (depends on 14) The shed portion as recited in claim 14, wherein the first hinge element is a wall tube that, when the shed portion is in an assembled state, is at least partly disposed within the blow molded plastic wall panel, and the second hinge element is a door tube that, when the shed portion is in an assembled state, is at least partly disposed within the blow molded plastic door. ### Claim 16 (depends on 14) The shed portion as recited in claim 14, wherein when the shed portion is in an assembled state, the blow molded plastic door has a range of motion of about 180 degrees relative to the blow molded plastic wall panel. ### Claim 17 (depends on 14) The shed portion as recited in claim 14, wherein when the shed portion is in an assembled state, the blow molded plastic door is fully open, the blow molded plastic door is positioned at an exterior side of the blow molded plastic wall panel. ### Claim 18 (depends on 14) The shed portion as recited in claim 14, wherein when the shed portion is in an assembled state, the blow molded plastic door is rotatable about both the first axis and the second axis. ### Claim 19 (depends on 14) The shed portion as recited in claim 14, wherein when the shed portion is in an assembled state, the blow molded plastic door has a range of motion of about 90 degrees about the first axis. ### Claim 20 (depends on 14) The shed portion as recited in claim 14, wherein when the shed portion is in an assembled state, and the blow molded plastic door is open to a position more than 90 degrees relative to the plastic wall panel, the first link and the second link extend out from a recess cooperatively defined by the blow molded plastic wall panel and the blow molded plastic door. ### Claim 21 (depends on 14) The shed portion as recited in claim 14, wherein when the shed portion is in an assembled state, and the blow molded plastic door is fully closed, the first link and the second link are received within a recess cooperatively defined by the blow molded plastic wall panel and the blow molded plastic door. ### Claim 22 (depends on 14) The shed portion as recited in claim 14, wherein when the shed portion is in an assembled state, the blow molded plastic door is configured to assume a state in which the blow molded plastic door is fully closed, and the first link and the second link are received within a recess cooperatively defined by the blow molded plastic wall panel and the blow molded plastic door. ### Claim 23 (depends on 14) The shed portion as recited in claim 14, wherein when the shed portion is in an assembled state, the blow molded plastic door is configured to assume a state in which the blow molded door is oriented at a position of 90 degrees, or less, relative to the plastic wall panel, and the first link and the second link remain in a recess cooperatively defined by the blow molded plastic wall panel and the blow molded plastic door. ### Claim 24 (depends on 14) The shed portion as recited in claim 14, wherein when the shed portion is in an assembled state, the blow molded plastic door is configured to assume a state in which the blow molded door is oriented at a position of greater than 90 degrees, relative to the plastic wall panel, and the first link and the second link extend out of a recess cooperatively defined by the blow molded plastic wall panel and the blow molded plastic door.
