Patent number: 11686137Abstract: A hinge has a first component that pivotally supports a second component of the hinge. The first hinge component carries an energy harvesting switch having a movable operator such as a spring-projected plunger that is positioned to be depressed or otherwise moved by the second hinge component in response to relative pivotal movement of the first and second hinge components. If a gate is fastened to the second hinge component, at least some of the weight of the gate is transferred from the second hinge component to the first hinge component. When the gate is pivoted away from a closed orientation toward an open orientation, the second hinge component moves the operator of the energy harvesting switch thereby causing the energy harvesting switch to emit a radio frequency signal.Type: GrantFiled: September 28, 2021Date of Patent: June 27, 2023Assignee: ERGOMAT, INCInventors: John Joseph Girard, Claus Munch Lendal
