Access control for animal feeding point, has rectangle formed by horizontal and vertical bars, with lever arm pivoting to occupy closed vertical position or angled open position, with locking element carried by upper horizontal bar

摘要

The access control barrier consists of two horizontal bars (1, 2) connected, in the same plane, by vertical bars (3, 4). Each pair of vertical bars and the horizontal bars forms a vertical rectangle, which corresponds to a place for an animal head, and is completed by a lever arm (5), mobile between a no access vertical position and an angled position, which allows access. The arm pivots around a central axis (6), carried on an elbow bar (7) and is locked in the central position by a locking element (25), carried by the control beam (8).
