ABSTRACT:
A closer device for a gate such as a swimming pool gate has relatively rotatable arms (for connection respectively to a gate and gate post), the arms being connected to a closer body having an axis parallel to the hinging axis of the gate on the gate post. The closer body has an elongate piston mounted within cylindrical gas chambers on respective sides of the piston and a relief profile on the exterior of the cylinder to engage with respective mounting elements for the arms whereby, upon relative rotation of the arms responding to gate movement, the piston moves axially within the gas chambers and a spring within the body urges the piston towards the position corresponding to a gate closed position. A gas controller permits unrestricted opening of the gate and control of closing speed.
