摘要: A self-closing gate (10) is pivotally mounted between a pair of spaced gate posts (11, 12) to selectively close the gateway therebetween. The gate (10) has end stiles (20, 22) provided with stub axles (21, 24) journalled in bushes (16) fitted in gate support members (14) fixed to the gate posts (11, 12) and counterweights (43) are adjustably mounted on the stiles (20, 22) to return the gate (10) to its normally closed position. Tensioned flexible wires, cables and/or chains (28-33) are strung between the stiles (20, 22) and they support a vehicle buffer (37) which has a bulbous central portion (39) which is engaged by a vehicle (41) to open the gate (10).To enable the gate (10) to also be swung open about a substantially vertical axis, one of the stiles (22) may include an outer stile (23) fixed on the stub axle (24) and an inner stile (26) releasably connectable to the stub axle (24) (via a socket (25)) and to the outer stile (23) (via a pivotal cap 27).A catch assembly (50), operated by the wires, cables or chains (28-33) may be provided to releasably lock the gate (10) in the closed position, the catch assembly (50) being releasable when the vehicle engages the gate (10).
