Entrance control mechanism
An entrance control mechanism, a barrier arrangement and an animal handling apparatus. the entrance control mechanism is for controlling a barrier member which can open in first and second opposite directions from a closed position, the mechanism comprising first and second stop members which are locatable on opposite sides of the barrier member in the closed position, and which are each selectively movable between an engaged position preventing the barrier member moving therepast, and a disengaged position in which the barrier member can move past the respective stop member, the mechanism being configured such that if a barrier member is urged against either the first or second stop member when in an engaged position, from a respective first or second open position, the respective first or second stop member will be moved to a disengaged position to allow the barrier member to move therepast, the mechanism being configured such that if the barrier member is urged against the first stop member from the first open position the first stop member will move to a disengaged position, but the second stop member will not move to a disengaged position, and if the barrier member is urged against the second stop member from the second open position, the second and first stop members will move to a disengaged position.
