Thread: Parliament hinges.

Parliament hinges eh?

First you need a committee to discuss the pros and cons of said type of hinge, discusing things like environmental impact and sustainability, political correctness, cost effectivness (ie. checking that we are wasting money), welfare support, International political impact and exactly which department will be given the task of instalation.

This is followed up by a Royal Inquirie, to ascertain weather the information gathered by the committee is correct.

This usually results in a costly referendum, were the leader of the opposition is heard to say "God save the Queen, because know one can save Ponce!"


Are you sure you can afford these hinges????

Ponce,

For what it is worth.

I have not had any experience with these hinges but when I use trickier hinges, I normally use drawings or make models of the hinges and connect them to some scrap. That way I get to understand how they work and how to fit them.

If you haven't already purchased them, simple models can help you to determine what size you need.

Ponce, now that the comedians are out of the way lets get serious. Parliament Hinges as you would know are a wide leaf hinge which allows a door to open right back against a wall, even when the door is set into a recess.
How much extra throw the hinge has will determine how careful you have to be on the lock stile because, as you can appreciate, the door will need more clearance on that side due to the offset hinge pin. You can usually get away with just a little wider gap than usual and if the door is particularly thick you can bevel the inside edge back a bit.

You can work out the clearance you need using the good old Pythogoras' theorum. If you measure from the hinge pivot to the front of the door rebate on the lock stile, that gives you the hypotenuse of a triangle where the shortest side is the distance from the inside edge of the door to the hinge pivot and the second longest side is the maximum width the door can be. You can use the 3, 4, 5 rule or Pythag's theorum (a2 + b2 = c2) to work out the maximum size of the door.

Eg. If you are 50mm out from the front of the door, and the door is 40mm thick, the short side (a) is 90. If the distance from the hinge pivot to the front of the door rebate is 920mm (c), then you can work out that your door must be no wider than approx. 915mm to clear the edge of the rebate. Add some clearance to that and you should be right.

Hope that makes sense.

Or you can draw the opening out full size on the floor or a piece of ply. Then draw in your pivot point and strike an arc through your doorway, this will give you the same answer as Silent's method but without the neccesity for calculations (and possible miscalculations ).

Mick the mathematically inept

Funny isn't it. Sitting here in my chair, the mathematical way was the first thing that popped into my head, but if I had to actually do it, I'd probably have done it Mick's way. There you have it - the difference between theory and practice.

Speaking from experience, for a 100mm p hinge I'd have allowed about an extra 2mm over normal and just hung the damn thing.

But then what would you have done for the rest of the day?

hung another dozen doors.money money money

Let'e go back to that calculation, two thirds of the square root of FA?

Now I know that Pommy soccer players on a diet of sugar give us Sweet FA but what is FA?

F*&% All

I had some parliament hinged patio doors fitted by a contractor last month. I felt a bit odd using a contractor just for fitting some doors, but by the end of the experience I was so happy it wasn't my problem...

The two experienced carpenters (not apprentices, but guys who had been in the trade for 20 yrs each) took two full days to hang the doors!! Lots of swearing about parliament hinges, and lots of grumbles about how much money they were losing...
