Abstract
A gas spring is connected between a cabinet and a lift-top lid and releasably holds the lid upwardly in a fully open position with respect to the cabinet. Gravity automatically pivots a safety latch into latching relation with the cylinder of the gas spring as the lid approaches its fully open position. If the gas spring loses pressure, the latch operably engages the cylinder to mechanically hold the lid in its fully open position and to prevent the lid from falling toward its closed position.
