Hinged wood bed floor (lock?)

[LowLifeS10]

Hi, we are doing a hinged wood bed floor in a steel frame with sheet metal around it.

But we havent figured out how we'll lock it nor open it. Dont want no ugly big thing sticking up in the bed. A small handle or something that you may turn to open/lock it like on the regular bed covers? As it needs to be in the wood area how can we attach it (handle) to the wood?





Any great ideas?
