Abstract
A device (14) allows a door of a balance draft shield enclosure (12) to be activated by a carrier fork (4) of a robot (5). The vertically movable draft shield door (13) sets open an access opening in a raised position and closes the opening in a lowered position. A door-lifter with a force-application element (41) is connected to the draft shield door for application of an upward-directed vertical force. A transmitting mechanism (15), standing clear of the balance (11) includes a force-receiving element (20, 21, 26, 27) that is moved vertically by the carrier fork, between upper and lower end positions. It further includes at least one direction-reversing element (22, 23, 24, 25, 29), coupled to the force-receiving element for coupling to the force-application element, a return spring (28), and a spring-biased locking latch (30).
