Access frame for animal stall has screen to prevent direct access to frame opening for passage of humans

摘要

The frame (1) supports a closure door for an animal stall, especially for a cow. The frame is mainly flat and has a passage (2-4) accessible from the front with a passage for a person (4) defined between two uprights (7,8). There is a screen (9) oriented towards the interior of the stall to mask frontal access to the passage. The screen forms a chicane to prevent direct frontal access to the passage.
