ABSTRACT:
A handle arrangement for a hot water tap or faucet which requires an axial and rotational movement of the handle in order to turn the tap "on" or a rotational movement only, in order to turn the tap "off". When applied to a hot water tap the handle arrangement provides a safety device against rotation by young children as the combination of movements is difficult or impossible for young children to overcome. The arrangement comprises a spindle member 11 which is attached to an existing tap spindle 18 by grub screws 19 and co-operates with a drive member 13 fixed to the handle to provide a ratchet arrangement between a drive member 13 and spindle member 11. The ratchet arrangement allows the tap to be turned off merely by rotation of the handle but does not engage when the tap is rotated in the direction to turn the tap on. A hexagonal protrusion 14 inside the handle co-operates with the handle member 11 to cause rotation of the handle when the handle is depressed axially inwardly.
