## Abstract

A fixture for delivering a first fluid over the basin of a sink includes a supply inlet and a delivery outlet for the fluid, the inlet connected to the outlet through a hollow body of the fixture, the hollow body including two straight, hollow metal tubes: a first tube arranged to be mounted next to the basin of the sink in use, and a second tube joined to the wall of the first tube so as to project out over the basin of the sink in use. One or more inserts are provided inside the first metal tube and together define a curved elbow duct inside the first metal tube for guiding the fluid from the first metal tube into the second metal tube. The tubes can be cut at relatively low cost from conventional rolled steel tubing, and the curved elbow duct limits pressure losses inside the first tube.

## Claims

### Claim 1

A fixture for delivering a first fluid over the basin of a sink, the fixture comprising a supply inlet for the fluid and a delivery outlet for the fluid, the inlet being connected to the outlet through a hollow body of the fixture, the hollow body comprising two straight, hollow metal tubes: a first tube arranged to be mounted next to the basin of the sink in use, and a second tube joined to the wall of the first tube so as to project out over the basin of the sink in use, one or more inserts being provided inside the first metal tube, which inserts together define a curved elbow duct inside the first metal tube for guiding the fluid from the first metal tube into the second metal tube.

### Claim 2 (depends on 1)

The fixture of claim 1 for additionally delivering a second fluid over the basin of the sink, the fixture comprising a second delivery outlet for delivery of the second fluid, the second delivery outlet arranged for connection to a supply of the second fluid.

### Claim 3 (depends on 2)

The fixture of claim 2, wherein the second delivery outlet is connected to the supply of second fluid via a pipe which runs through the curved elbow duct.

### Claim 4 (depends on 1)

The fixture of claim 1, wherein the inserts extend into the second tube.

### Claim 5 (depends on 1)

An arrangement for drying a user's hands at a sink, the arrangement comprising the fixture of claim 1 in combination with a motor-driven fan unit, the delivery outlet being an air nozzle, and the fan unit being connected to the supply inlet for forcing drying air through the air nozzle via the curved elbow duct.

### Claim 6 (depends on 5)

The arrangement of claim 5, the arrangement comprising a plurality of said air nozzles, at least one air nozzle being provided on each of two branch ducts extending from the second tube.

### Claim 7 (depends on 5)

The arrangement of claim 5, wherein the inserts are foam inserts.

### Claim 8 (depends on 7)

The arrangement of claim 7, wherein the inserts are Expanded Polystyrene (EPS) inserts.

### Claim 9 (depends on 5)

The arrangement of claim 5, wherein the fixture additionally comprises a water delivery outlet connected to a water supply.

### Claim 10 (depends on 9)

The arrangement of claim 9, wherein the water delivery outlet is connected to the water supply via a pipe running through the curved elbow duct.

### Claim 11 (depends on 9)

The arrangement of claim 9, wherein the water delivery outlet is located on the second tube.
