摘要

The device (1) has a link apron (2) comprising multiple articulated connected sliding and abeyance links (3, 4) and displaceably guided in a guide (5) along two displacement directions (7, 9). The sliding link is subjected to displacement in the guide, and the abeyance link is floatingly arranged at the guide by the sliding link. A window (32) for examining the link apron is arranged at the abeyance link, where a length (L4a) of the abeyance link is oriented along the displacement directions and is larger than a length (L1a) of the sliding link. A grasp box (37) manually operates the apron.
