  • Patent number: 4565343
    Abstract: A support mechanism for raising and lowering a terminal monitor comprising an upper assembly and a lower assembly and a plurality of pivotable arms interconnecting the upper assembly and lower assembly. The upper assembly includes an upper plate, which supports the monitor, and an upper slidable plate slidably coupled to it, and the lower assembly includes a base plate and a lower slidable plate slidably coupled to it. Due to the way the pivotable arms are coupled to the various plates, when the upper slidable plate is driven with respect to its associated upper plate, the arms pivot either to raise or lower the upper assembly and its monitor load with respect to the lower assembly.
