Toileting  

For certain young males who have the habit of crossing their legs when sitting on the toilet a flexible urine deflector is inappropriate.  The alternative is a rigid deflector which prevents leg crossing and facilitates urination into the pan.  The device has no moving parts and is intended to be fixed to the toilet seat as a permanent attachment.  In the interests of hygiene the deflector can be covered using a disposable sandwich bag.  The bag is easily disposed of after each use and permits a single toilet to meet the needs of multiple users.
The requirement was for a 'child-proof' locking arrangement on a toilet chair tray.  This was solved by positioning the bolts in such a way that the person was unable to either reach or  dislodge them.
