Operator safety device

摘要

An operator safety device includes a plurality of covers for covering parts of a machine to protect an operator against contact with these parts when the machine is in operation. At least some of the covers are movable between a closed position where the covers do not cover these parts and the latter are readily accessible and constitute a danger of accidents. A switch is operable for shutting down the machine when at least one of the covers moves from the closed into the open position. A linkage connects the covers with the switch for actuating the latter whenever at least one of the covers moves from the closed into the open position.
