Door wedge lock

Door wedge lock "unfinished project" this file is a mock up of my idea for a door wedge lock. I'm hoping you reading this might help finnish this,,,,i've got about ten minutes before dinner so i didn't have time to think it up and finnish the drawing.....

The idea is you slide the unopened device under a closed door and then open the wedge up, then lock it so door is now locked by wedge. """"lockable door wedge"""""

It seems to me often needing to lock a door but not time to put a lock on the door,,,,so a lockable wedge would be the go.
Perhaps you ain't about to have dinner and can fix it up for us all.
I look forward to seeing if anyone picks up on this. i'll check back later.
Bye for now and be well from Will and Mr Data :) :]
