I'm trying my hand at building a frame to go in the back of a van-car (Peugeot Partner) to create some storage and sleeping space. I've screwed together a frame:
The LHS section goes over where the back seats were. 2 pieces of ply will go on top of the unit, hinged. This will then fold out to form a backrest, and hinge down to make a flat surface for sleeping etc. Other conversions use a piece of wood to support the 'backrest' - usually against the front seats. The same piece of wood then supports the ply on the floor in the flat position. This is fine - it seems to work, but looks clumsy. Any other ideas about how to support the ply at say upright and flat?
My next problem is securing the various cabinet tops/seats. I'd like something that stretches or cams to latch the tops securely on the move. I suppose a bungee/hook would do it. Any better ideas?
And holding the tops in the open position - something reliable and unobtrusive. I've got a 50N gas strut, but that seems an improbable amount of force for a c.2kg bit of ply. A formula suggests it might work:
