Multi-hinge tonneau cover
A tonneau cover comprising: (a) a plurality of panels; (b) one or more hinges between each panel of the plurality of panels so that the plurality of panels are rotatably connected together, wherein some or all of the one or more hinges include: (i) a plurality of expansion links that are movably interconnected together, some of the plurality of expansion links including: (1) one or more expansion projections; (2) one or more pockets that receive all or a portion of the one or more expansion projections from an adjacent one of the plurality of expansion links; and (3) one or more expansion stops that restricts movement of the one or more expansion projections from the adjacent one of plurality of the expansion links that extend within the one or more pockets; wherein the one or more hinges rotate so that the one or more hinges form of angle of about 90 degrees or more and about 225 degrees or less.
1. A tonneau cover comprising:
(a) a plurality of panels;
(b) one or more hinges between each panel of the plurality of panels so that the plurality of panels are rotatably connected together, wherein some or all of the one or more hinges include:
i. a plurality of expansion links that are movably interconnected together, some of the plurality of expansion links including:
(1) one or more expansion projections;
(2) one or more pockets that receive all or a portion of the one or more expansion projections from an adjacent one of the plurality of expansion links;
(3) one or more expansion stops that restricts movement of the one or more expansion projections from the adjacent one of the plurality of expansion links that extend within the one or more pockets; and
(4) one ore more hinge steps located along an upper surface,
wherein the one or more hinges rotate so that the one or more hinges form an angle of about 90 degrees or more and about 225 degrees or less.
2. The tonneau cover of claim 1 , wherein each of the plurality of expansion links move so that one or more of the plurality of panels rotates about 20 degrees or more and about 60 degrees or less.
3. The tonneau cover of claim 1 , wherein each of the plurality of expansion links move so that one or more of the plurality of panels rotate about 25 degrees or more and about 35 degrees or less.
4. The tonneau cover of claim 1 , wherein some of the expansion projections are movable within the one or more pockets so that when the one or more expansion projections move within a pocket of the adjacent one of the plurality of expansion links the hinge rotates one or more of the plurality of panels.
5. The tonneau cover of claim 4 , wherein the one or more expansion stops are located at an end of each of the one or more pockets.
6. The tonneau cover of claim 1 , wherein a length of the one or more pockets, a length of the one or more expansion projections, or both are selected to determine the angle the one or more hinges rotate.
7. The tonneau cover of claim 1 , wherein some or all of the plurality of expansion links include one or more spacer recesses.
8. The tonneau cover of claim 1 , wherein the one or more hinge steps receive a portion of the upper surface of an adjacent expansion links so that an upper surface of the hinge is planar when the hinge is in a closed position.
9. The tonneau cover of claim 1 , wherein each of the plurality of panels includes or is connected to a frame and the frame includes one of the one or more expansion projections or one of the one or more pockets that connects the frame to the plurality of expansion links, thereby forming one of the one or more hinges.
10. The tonneau cover of claim 1 , wherein one or more of the one or more hinges includes one or more spacer bars.
11. The tonneau cover of claim 10 , wherein one or more of the plurality of hinges is free of the one or more spacer bars.
12. The tonneau cover of claim 1 , wherein the one or more hinges includes between three and six expansion links.
13. A tonneau cover comprising:
(a) a first panel;
(b) a second panel; and
(c) a hinge connecting the first panel and the second panel, wherein the hinge includes interconnected expansion links, each of the expansion links comprising:
(1) an expansion projection;
(2) a pocket that receives the expansion projection of an adjacent expansion link;
(3) an expansion stop that restricts movement of the expansion projection of the adjacent expansion link positioned in the pocket; and
(4) a hinge step located along an upper surface of the expansion link that receives a portion of an upper surface of the adjacent expansion link;
wherein the expansion projection of the adjacent expansion link moves within the pocket to rotate the hinge, thereby rotating the first panel, the second panel, or both.
14. The tonneau cover of claim 13 , wherein the expansion stop is located at an end of the pocket.
15. The tonneau cover of claim 13 , wherein each of the expansion links include a spacer recess.
16. The tonneau cover of claim 13 , wherein each of the expansion links includes a spacer recess and an expansion cap is secured to the spacer recess by a fastener.
17. The tonneau cover of claim 16 , wherein a pair of expansion caps are secured to opposing ends of each of the expansion links.
18. The tonneau cover of claim 13 , wherein a spacer bar is positioned between the expansion links to define a gap between the expansion links and space apart the expansion links.
