  • Dynamic furniture featuring pendulum-like motion
    Patent number: 11759015
    Abstract: A dynamic furniture system includes a first frame portion; a set of rollers mounted to the first frame portion; a second frame portion including one or more rockers having a roller-interface surface having a curved profile; wherein the set of rollers interface with the roller-interface surface of the rockers such that the second frame portion is moveable relative to the first frame portion; a set of one or more electromagnets mounted to or integrated with the first frame portion or the second frame portion; a set of one or more magnetically-interactive elements mounted to or integrated with a different one of the first frame portion or the second frame portion; and an electronic control system configured to vary a parameter of electrical energy supplied to the set of electromagnets over time to induce back and forth motion of one of the first frame portion or the second frame portion.
