How do I make the gates in my fence work properly?

Asked by rojo (24159points) October 4th, 2016

I am constructing a wood fence on a slope. The posts are, of course vertical.

If I mount a gate to the post with the hinges horizontally, when I open the gate it will run into the slope before it is fully opened.

Is there a way to mount the hinges so that when the gate opens it will swing upward following the slope of the hill?

What if I mount the hinges parallel with the slope, will that work? Is there a mathematical formula I can use? The hinge pins need to be in line with each other but can I offset them from the space (crack) between the gate and the fence perhaps?

To mount the hinges parallel to the slope, stick that post in perpendicular to the slope.

Or you could have a sliding gate that goes sideways instead of swinging

Or, more complicated, a parallelogram that lifts one end as it swings kind of like this picture.

Or simply swing the gate out over the slope instead of back into it.

I searched for “hinges for gates on slopes” to get this and this … and those were just in the top 5 results. I’ll bet you can find some other good solutions.

Of course, you’ll need to keep in mind that any offset that causes the gate to rise to clear the upward slope is also going to get gravity involved: the more that the gate opens inward, the heavier it gets. So if it’s an iron or heavy wood gate to begin with, that’s a definite consideration.

Mount the gate vertically with a counterweight, so that it works like a garage door.

Rolling gate like this

Mount the gate via the hinges to the downhill post.

@kritiper it is a pair so that is really not an option.

One thing I did notice is that the vast majority, if not all, the offset hinge options are in the UK.

Run that section of the fence where the gate will be along the width of the slope instead of against it.
