Abstract
A double hinged cattle stanchion (10) is disclosed and includes a pair of release stanchions, a 'J' shaped fulcrum stanchion (15) and a release stanchion (14), both of which are pivotally attached between a pair of fixed stanchions (13). Fixed stanchions (13) are attached in upright pairs between a horizontally extending top rail (11) and a horizontally extending bottom rail (12). Fulcrum stanchion (15) includes a main elongated portion and a perpendicularly depending leg member. A fulcrum offset member (16) is perpendicularly attached at a midpoint along the main elongated portion and includes a fulcrum bracket (17) at its extending end. Fulcrum bracket (17) provides a pivotal attachment point for release stanchion (14) via a standard pivot bolt (18). The extending end of the depending leg portion of fulcrum stanchion (15) is pivotally attached to a base bracket (20) located between a pair of fixed stanchions (13) on bottom rail member (12). First and second stanchion heads (28) and (29) are attached to the upper ends of fulcrum stanchion (15) and release stanchion (14) respectively. Each stanchion head includes a pivotally elongated latch member being disposed to engage actuator rod (21) which is rotatably and axially attached along top rail (11).
