Where can I find this stairgate?

[grovelodge]

When my son was small I had a stairgate fixed across the bottom step of the stairs. It was made of wood, hinged to the post on one side with an opening latch on the other. But the magic thing was that when it opened it could be raised and folded back against the stair rails rather than opening outwards away from the stairs. That gate is long gone, but now I want another one, this time for my granddaughter. But I can't find one anywhere. Does anyone have any suggestions?

We got a gate from mothercare that can be actually taken off the wall. It has no bar at the bottom so there is no risk of tripping.
We wanted something to go across the gap between the kitchen and lounge, but didnt want it on all the time and this is perfect.
Think was about £20.

I've got one of those roller blind type ones on odd gap at bottom of stairs which obviously winds in when not in use. I would say however DO NOT believe anything it says about being a one-handed operation. It is a neat solution, but really quite fiddly.
