European lock question

[MrB]

toomush, I know what you mean about the way the cam operates on a euro cylinder, but that's just because you see how the handle and locking mechanism are arranged now. Someone decided the convenience of that design outweighed other considerations. But I argue that back in the beginning, someone could have designed the first one differently and had the pins upwards, if they had had a mind to.

If you'd ever had to endure 60MPH winds at -40 degrees with snowflakes that are so hard they could break skin... you'd be happy to have a door swing outward.

And as for driving in Canada, we have to drive on the wrong side of the road. Somebody put the darn steering wheel on the wrong side of the car!

Yeah , i just remembered .
When i went to the US and Canada, they open their doors "out" , not "in" like we do.

I kept pushin on them the whole time i was there
And off course when i was walking out of a building i was pullin on them

Why do they do silly things like that !!

Don't even start me on their drivin, them nuts drive on the "wrong" side of the road, i won't tell ya the havoc that caused

Dunno, i think they were glad to see the back of me !

Actually its because of fires. If your in a large building and there is a fire and everyone panics and line up at the door how are you supposed to open in inward?

Nw ofcourse someone can come up with a reason why this is bad but it makes sense to me. Plus all houses have doors that open "in", and usually a screen door that opens "out"

[digital_blue]

I don't know about where you are, but we call those outswinging house doors "storm doors", and for a reason.

[RangerF150]

Sounds reasonable to me .
But we have fires over here too, no fire officer seems to have a problem with the current setup.
That's not to say its right .

That said , all firedoors over here open outward's , just "regular" doors open inward.

You make a pretty good point .....


Totally off topic, but there ya go

Of course anything could be designed differently hence there are so many locks about but in this instance the euro nine times out of ten is operating a simple lever system. If you were to turn the lever lock part upside down it would put extra stress on the lever springs because the spring now has to hold up the lever as well. The way they are now means that gravity holds the lever down and the spring provides resistance to push it back down after clearing the gate. If the springs fail on an upside down lock it would be impossible to unlock it but with the springs on top you still have a chance because of gravity. Even though the keyway is prone to getting more dirt and muck in it its easier to deal with this than having to drill the lock case and door because of lever failure.
