On Mums side gate it's more 'friendly' in that the initial faces of
the part on (what would be the) slam has curved faces on both sides so
you don't have to manually 'operate' the latch to latch it (just
unlatch it).

A bit like this but with 'ramps' that are more shallow:

/| |\
/ | | \
/ | | \
/ | | \
/ ----- \

|_________________|

You just push it shut to about the right place and it latches (from
either direction).

Yes, that's exactly what I want, as I said I've seen big 'field gate'
sized ones of these but nothing suitable for a small 'garden gate'
sort of gate.

Well, the slam part could be 3D printed and be reasonably hard wearing
and could be fashioned to mount on whatever makes up the existing slam
(tube, square, flat etc) and the 'latch' only really needs to be a
strip of steel plate (say 25 x 5mm section) with a hole drilled off
centre (making the nose slightly heavier) and with the tang having a
slightly rounded lower edge section to help it ride up the ramps and a
stop to stop it dropping below horizontal?

The best sort of thing I can think of is a ring latch something like this:-

but without the slotted bit that constrains it from lifting right up
out of the way of the gate post. However I suspect that the above
without the constraint won't be very sound mechanically.

It's made a bit awkward because the gate is quite high and has netting
across all of it so you can't reach through to undo the existing cabin
hook and you can't use the drop-over U type latch because there's
netting right to the top of the gate and the gate post.

Does anyone have any bright ideas for this?

Neat, but ironically it would not be horse-proof! I've had horses that
could operate the pull-down bar latch in American barn sliding doors.
And they defeat people who have not seen one before.

I can't really see how it works, it doesn't have to be horse proof in
our case, just chicken proof. We do have lots of old horseshoes

Dont believe that a horse has anything it can pull up the ring with.

They cant even use their teeth for that, the front of the head wouldnt fit.

Its very obvious, you pull up on the ring to release the latch.

Then the horseshoe is moved by the gate to let the latch
lock again and the horseshow stops the gate from swinging.

It will do that fine.

They would put their nose under the bit of horseshoe on their side, and
lift it up. Some might use their lips.

American barn doors are typically solid up to about 4 feet, and the bit
above has vertical bars essentially like prison bars, in a box-section
frame. To unlatch, you grip the bar nearest the opening, and slide it
upwards a few inches. They are quite stiff. But once a horse has figured
it out, it uses its nose or lips to do what you would do with your hand.

That one isnt livestock proof. But would be fine for a chicken coop.

He might make that claim and it might be true for cattle.

But the whole of the moving bit is solid, so it could be raised from the
horseshoe by applying a suitable moment as well as a straight upwards
force. Horses can untie knots with their teeth, I am confident that some
could defeat that. And mules even more so.

It isnt a claim, he shows it cant be done by livestock.

For all livestock in fact.

horseshoe by applying a suitable moment

Nope, because the movement has to be applied to
the big pin with the ring at the top of it and only
the ring is accessible with the gate latch locked
and no horse has anything that can lift that ring.

as well as a straight upwards force.

The only thing a straight upwards force can be applied
to is the ring and no horse has anything that it can use
to apply a straight upwards force to that ring.

Horses can untie knots with their teeth,

But there is no way to get their teeth onto
that ring because their jaw wont fit between
the gate post and the gate vertical frame.

I am confident that some could defeat that. And mules even more so.

You have no basis for that confidence.
Its basic physics, neither have anything
to grip the small ring with and thats the
only way the latch can be released, with
an upward force on that small ring which
is in the small space between the gate
post and the vertical gate frame.

He didnt rattle the ring, he showed that upward force
on the horseshoe, the only thing livestock can do, doesnt
lift the vertical thing that is attached to the horseshoe.

And thats obvious from the basic physics, that it wouldnt
lift it, it would jam in the outer and not rise.

And as I pointed out, if you combine a moment with the upward force you
can cancel out the friction in the central bearing.
