Push-pull chain and actuator
A push-pull chain and actuator for opening and closing a hinged window, door or other panel. The chain has a plurality pairs of inner links (14,14') and outer links (15,15'), alternate pairs of said inner links (14,14') being sequentially coupled to alternate pairs (15,15') of said outer links by parallel drive pins (19) with bushings (20) that separate the pairs of inner links (14,14') and outer links (15,15'). The inner links (14) and the outer links (15) on one side of said bushings (20) are shaped to allow the chain (10) to bend freely past a configuration in which the chain forms a straight line in one direction and only to a limited extend in the opposite direction, whilst the inner links (14') and the outer links (15') on the other side of said bushings (20) allow the chain (10) to bend freely past said configuration in said one direction and only to an extend in the opposite direction which extend is greater than said limited extend. The drive pins (19) are at said one side of the chain (10) fitted with increased play in the holes in the bushings (20) to provide lateral flexibility of the chain in two opposing directions.
