Hi,
I've just got home from a few days in hospital. Looking round the place I noticed that the doors between the main ward and various side wards/offices/sluice rooms etc. all had three hinges. The doors are good massive hardwood doors and the hinges each have two ball-races.
The bit that intrigued me was that each door has three hinges, one at the bottom and two, quite close together, at the top of the door.
I've heard that the (two) hinges on a domestic door should be positioned 'six down and nine up' but what's the rationale for this two at the top and one at the bottom layout?
If it's to withstand the impact from beds or trolleys, surely the two hinges should be at the bottom?
