Abstract
A power-operated medical examination table having safety mechanisms for preventing injury or damage should someone or something become entrapped beneath the top of the table as it descends. The table includes a pedestal base having an extendable and retractable column. The top normally rests upon a load-bearing member which may be selectively raised or lowered under power to extend or retract the column. Should the top engage an obstruction during a lowering operation so that a separation occurs between the load-bearing member and the top, a sensor detects such separation and immediately interrupts power to prevent continued retraction of said load-bearing member. The table also includes at least one power-operated outer top section that is hinged to the central top section and is supported by a second load-bearing member and power drive arranged to constitute a secondary safety mechanism.
