摘要

The hinging grille is for cowstalls for short periods, having adjustable slots for securing the animals and a horizontal hinge axis suspended to swing in their lengthwise direction. The grille (9) hinges by its upper lengthwise beam (8) in two or more stationary bearings on brackets (2), flange-mounted on fencing posts (1) cemented into the floor or on a wall. The hinge axis is situated centrally above the manger (10), roughly at the level of the animal's head. The grille can have on the bottom lengthwise beam a locking bolt (31) engaging with a curved segment (34) in various positions, the segment being secured at one end to one or the posts.
