Help identifying/adjusting sliding patio door

Hi folks,

I’m hoping someone can help me identify this faulty patio door, and/or provide some pointers for me to fix it. I moved into the house recently, there’s no documentation on the door but the lock is marked “fuhr infront”. The door seems to be out of alignment somehow as you have to lift/push the right-hand side as you turn the locking handle to close it, otherwise all the lock bolts don’t line up. There isn’t any obvious adjustment screws on the door.

The door has no key lock, but a large handle that moves 180 degrees to open/close it. Moving the handle makes the door move toward you about 80mm, so that it can slide in front of the other static side.

I’m attaching some photos that will hopefully give you a better idea!

Any help would be much appreciated.

look down the sides of the sliding door, top and bottom, should be a hole ( or a grommit filled hole ) , behind there may well be a screw on the side of the wheel bogey to adjust the wheel height, maybe about 2-3 inches in. Just sounds like its out of alignment. Worst case scenario is a ' bogey ' may have completely collapsed
