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.
A control handle arrangement for a water tap with a fluid control valve of the kind having an operating spindle adapted for rotation in first and second opposite directions to respectively close and open said valve, said handle arrangement including a handle, spindle engaging means mounted on said spindle for mounting said handle on said spindle for axial movement of the handle thereon relative to said spindle between a normal position and a moved position, first drive means engageable, in the normal position of said handle, between said handle and said spindle engaging means for rotational driving of said spindle solely in said first direction, in response to rotation of said handle, to close said valve, said handle, in the normal position, allowing movement of said handle in the opposite direction independently of said spindle without affecting the position of said valve, and second drive means, in the moved position of said handle, between said handle and said spindle engaging means for rotational driving of said spindle in said second direction, upon rotation of said handle, to open said valve while simultaneously disengaging said first drive means between said handle and said spindle.
