Abstract:
1. A hinged, water control apparatus comprising: a first water control system component and a second water control system component-that is rotatable relative to said first water control system component about an axis of rotation from a first position to a second, rotation position, wherein said first water control system component is upflow of said second water control system component; and a first S-type flexible hinge and a second S-type flexible hinge each secured to at least one of said first water control system component and said second water control system component to allow said rotation, wherein said second S-type flexible hinge is established substantially beside said first S-type flexible hinge, and wherein each of said hinges has an upflow portion and a downflow portion and an intervening portion therebetween, wherein each of said two water control system components has a water flow proximate side and a water flow distal side, and wherein said first S-type flexible hinge, when viewed cross-sectionally from the side, comprises an upflow, first hinge portion that is established against said water flow proximate side of said first water control system component, a downflow, first hinge portion that is established against the water flow distal side of said second water control system component, and an intervening first hinge portion therebetween, wherein said second S-type flexible hinge, when viewed cross-sectionally from said side, comprises an upflow, second hinge portion established against said water flow distal side of said first water control system component, a downflow, second hinge portion that is established against the water flow proximate side of said second water control system component, and an intervening second hinge portion therebetween, said apparatus further comprising component retention improvement elements, a first of which is established as part of said upflow, first hinge portion, a second of which is established as part of said downflow, first hinge portion, a third of which is established as part of said upflow, second hinge portion, and a fourth of which is established as part of said downflow, second hinge portion.
