  • Patent number: 5829075
    Abstract: An adjustable foundation for use with a bed frame. The foundation includes a base part and an adjustable head end part. One or preferably a pair of improved hinges hingeably attach the head end part to the base part. Each of the hinges includes a first mounting plate and a second mounting plate pivotally connected to the first mounting plate, a hinge latch, a trigger pivotally attached to the hinge latch, and a catch fixedly attached to the second mounting plate. During the raising of the head end part the catch enters a selected one of the notches in the lower edge of the hinge latch to hold the head end part at a selected fixed raised position. When it is desired to lower the head end part the head end part is raised beyond the highest fixed raised position, which causes the catch to engage a trigger notch wherein the trigger establishes a lowering position for lowering the head end part.
