I am searching for a mechanical solution for my gate with lever and counterweights.
The space under my gate is too large when closed and my dogs can escape under. However the door opens up on an incline and if I put a wood flap on the bottom it would prevent it from opening fully due to the incline.
I'd like the flap to open up as the door swings open using pulleys and counterweights but can't figure it out.
Does anyone have suggestions?
Here is a drawing of the gate and how it slopes. It is at the top of a set of stairs from the sidewalk.
Here is a picture of the gate from the outside. Opens inward, slopes upward from there.
