Abstract: A shower device has a bar on which slide a spray head support and a manually operable grip. At least two continuous chains, one connected to the grip and another to the spray head support, pass over a respective pulley mounted at each end of the bar. At one end of the bar the pulleys of two adjacent chains are connected to rotate with one another and the pulleys at the other end of the bar rotate independently with one of the pulleys at one end of the bar over which passes the chain for the spray head having a larger diameter to vary the ratio of movement between the grip and the head.
