Latch mechanism for a gate

A latch mechanism for a gate, comprising:

• a main support;
• a first retention member having a first key aperture and a second retention member having a second key aperture, wherein the first and second members are spaced along a vertical direction on the main support so as to be separated by a vertical gap;
• a rotatable latch comprising:
• a latch portion;
• a seat;
• a first key portion extending in a first direction;
• a neck portion;
• and
• a second key portion extending in a second direction;
• the first and second key portions configured to extend through the first key aperture and second key aperture respectively;
• an axis of rotation extending vertically along the main support,
• wherein, when the rotatable latch is mounted on the first and second retention members, the seat is configured to rest against the first retention member restricting movement of the latch portion along the axis of rotation towards the first retention member, the first key portion is configured to be positioned between the first and second retention members, and the second key portion is configured to be positioned below the second retention member;
• wherein when the rotatable latch is mounted on the main support, the rotatable latch is rotatable about the axis of rotation between a receiving position in which the rotatable latch is disengaged from the gate and the gate is moveable between an open position and a closed position, or vice versa, and a latched position in which the rotatable latch is movable about the axis of rotation to receive a portion of the gate between the latch portion and the first retention member such that the latch portion restrains the gate in the closed position, wherein in the latched position the first and second key portions engage with the first and second retention members to prevent withdrawal of the rotatable latch;
• wherein in the area of the neck portion and the seat, the rotatable latch is configured to interact with the first retention member and the second retention member to provide a staged failure of the rotatable latch when the rotatable latch is in the latched position and under load against the gate.
