Cattle retaining mechanism in stable - has lockable pivoted upper arms and lower arms freely hingeable to U=bracket below

摘要

The mechanism is intended for retaining an animal, e.g. a cow, in a stall or the like. It comprises a suspension element (12-14) secured (7-11) to a fixed structure (2) and a U-bracket (3) anchored (4-6) to the floor (1). Two arms (17,18) horizontally pivoted (15,16) to the element have their lower ends hinged (21,22) to the upper ends of arms (19,20) whose lower ends are hinged (47,48) to the bracket. The hinges (21,22; 47,48) permit relative movement in two planes and a latch (35,37) permits the upper ends of the arms (17,18) to be locked in a closed position. In the open position the arms (19,20) converge downwards and extend downwards beyond the hinges (47,48). FL.
