A-Class Drop Down Bed Mechanism?

[Wissel]

Hey all,

Does anyone have any pictures of their drop-down bed mechanism?

Just need a few images showing how they work, as would like to build one in next van.

Or know of anywhere that sells the brackets?

This is the sort of thing I'd like to build, hinged from the roof:

Thanks.

You say hinged from the roof but actually they are fastened into the sidewalls.

Thanks.

I hope someone can come up with a supplier or manufactures name, I spent a few hours searching for a "drop down" mechanism a couple of week ago and drew a blank.

So to refine my above post, the front bed is attached to the sidewalls of the van I believe but this one might be different but not sure how far it lifts, search for project 2000 or P2K by Lippert https://www.outandaboutlive.co.uk/m...ed-installation-kits-launched-by-project-2000

It is more a scissor action, either powered by a winch with a strap or a big pair of linear actuators. The winch system is by far the less complicated. And as above mounted to the walls to distribute the downwards force

So far all I've found is a video of a guy swapping the gas struts on his Hymer, but it shows the mechanism well:

This is the bracket on the sidewall at N+B Polch, so that is the scissor type bracket.

As you can see there are two common methods for the lift mechanism, the scissors type and the four arm swing down as with the Hymer. It all depends on how you want the bed to operate, on the Hymer, and my Pilote A class the bed swings down and foward over the instrument console which moves the bed close to the windscreen to make full use of the van space. This works well with an A class as the screen is further forward than a coach built. If you want the bed to drop vertically you will need the scissor type. If you want the bed at the rear or central you will lose cupbard space with the swing down type.

Any good?

There's all sorts of fun with the geometry. One of the reasons we chose our Geist a-class over a Roller Team Pegaso was the bed dropped pretty much straight down. The Roller Team mechanism started with the bed at an angle against the roof and it swung backwards on an arc. It meant there was about half a locker length lost on both sides.

We used to have a Pilote A-Class with drop down bed as well. That bed is exactly what we want to build

I've done the drawings, and a 1.2m x 1.85m bed, that swings back towards the screen as it drops, will fit perfectly (without encroaching into hab area when down). We will lose about 30cm of wall cupboard space either side, but that's fine.

I may be able to make it a little larger (don't have the van yet, so working off drawings), but if not it will be fine as only a guest bed.

Think I might order some Meccano (assume it's still about?) and play with a few designs

 

[TheBig1]

usually plenty of used meccano on facebook local selling sites

Wissel If you are near the east side of the New Forest you are welcome to come and take some measurements.

 

[Wissel]

Resurrecting an older thread here as want to build this pretty soon.

I now have a pile of old Meccano to dial in a drop-down bed mechanism, but could really do with a good pic of an existing bracket as a starting point.

Does anyone have an image of a drop down bed mechanism from an A class?

 

[Oldrat]

Project 2000, Italy sell drop down beds.
Rhales conversions have done several.

You could try a motorhome breakers yard

 

[Rollingwheels]

Try googling pilote factory tour I was loo a while ago and I think that they showed them there

 

[Rollingwheels]

Sorry looking it should have read

Just taken a couple of photos of mine for you, its a 2017 Hymer can't see any manufacturer name on the parts.

 

[Manic]

I’ve a part photo( ignore the black strap)

Thank you Lenny HB & Manic

That's exactly what I needed

Now just need a free few hours...

David I know someone who took a dropdown bed out of a Chauson, I seem to remember it was the sort that came down over the table, not like an a class dropdown if you interested I will contact him he lives near herne bay Kent and wrote the motorhome off in an accident. Bob.

I can take some pics of my A class Burstner drop down bed if still needed?
I‘m at a site in the Lake District right now and it’s chucking it down so not going out on my push bike just yet!

That's cheap only a few quid more than just the struts.

Yebbut those mechanisms are for lifting a fixed bed base up and not for a drop down bed. Unless I’m reading that wrong.

Yep you are right, I thought the mech looked too simple but didn't read the discription.

 

[Ashy]

Me neither

Here’s a better photo
