发明名称 Gate
摘要 A gate assembly for an animal passageway has two barriers that, when in use, are in close proximity to each other in a closed position and can be moved in opposing directions to each other to be in an open position. The operation of the gate assembly to the open position is achieved by an operator using an operator-activated control mechanism. At least one barrier is configured so that when in the open position it does not intrude into the passageway and activation of the control mechanism is external to the passageway. The gate assembly is maintained in the open position until the operator operates the control mechanism to close the grate assembly. When the assembly is in the open position one barrier is in an upper position with respect to the other. The barrier are pivotally attached to a support at separate pivot points.
