Right angle drawer slide?

Yes - my mum has one in her apartment (in Sydney, Aus) - it works beautifully...

If no one beats me to it, I'll get a brand name from her and you can look them up.

This one has two identically sized racks (rectangular prisms) sitting side by side in the cupboard - one bolted to the cupboard door, the other pushed into the corner.

When you pull the door forward (it slides out like a big drawer), an arm underneath swings out under both racks, pulling the corner one into the cupboard space. I believe the first one swings out of the way on a hinge once it is fully extended, allowing access to the second rack.

The arm underneath has a track with bearings along each side - like this in cross section: [o___o]

As long as you don't yank it, it runs perfectly.

Thanks Robert, I look forward to manufacturer's name. Any chance of a more detailed drawing?

Someone threw out a KrisDel^TM one last night. It's lurking in Morrisons' car park in Vange, if you wannit <Splutter>.

Thanks Pete,

I actually tried the KrisDel™ but, in spite of all efforts, I could not make it fit. The biggest problem with that make and model was the oblong bearings (nuts) that they used. Also, Cat litter kept peppering me while I was trying to install the damn thing. Perhaps, an instruction sheet that was not written in a secondary language; "insert wodget befor you can gain access to primary function, then add screw "d" into socket "m", but must call manufacturerr for retuen policy if failing occurs". I suppose the devil is in the details though.

KrisDel™ needs to persevere much as Orville and Wilbur did don't you think?

Hi John,

Haven't heard back from mum yet! so can't give you a manufacturer etc. I have attempted a from-memory basic concept design - this may give you enough to get started. I'll get a picture sometime, however I live a good few hours by plane from the thing, so that won't happen until I can convince a sibling to take some snaps for me...

By the look of it, it went through a lot of prototyping to get it to market, so my feeling is you're in for some fun before you get yours working smoothly.

Here goes - (assume you'll understand the standard "warning do not build from this plan" disclaimer)... It's all housed under the L shaped bench corner. The two racks slide on tracks - I can't remember how the front one pivots around when fully extended, but it's not impossible to imagine ways that could happen...

The interlocking arms are underneath the racks - taking up about the bottom 3" of cupboard space. I'm pretty sure the arm on the front rack is fixed, while the other one slides all over the damn place.

By my plans the back rack wouldn't be pushed back into its corner when sliding the drawer back in (which the real one does very nicely)... so the angles are obviously quite important.

Good luck - I'll work on that photo!

also just to clarify - that bearing in the drawing both pivots on and slides up and down along the fixed arm. So in pic3, the bearing should really be at the very end of the fixed arm as it has stopped being able to roll along it and is now translating the forwards force on the front rack into pulling the back rack from right to left.

OK, how about the possibility of something simpler? This is just a real crude image in my mind right now, but what about instead of a complex gear/rack you use a pulley in the back of the pull out drawer which affixes to the back of the cabinet. You run a cable (cheap) from the pull out drawer through the pulley and to your sliding shelf? You will have to figure out the load for the spring assist cable. It might be aided by putting your corner shelf on two slides from an old pedastal cabinet (file drawer). You sound like you are handy so you could figure out how to make it work and it would be cheap. Let me know if it works....bkowal@veng.com

Dear Guest,

This Forum is filled with engineers. (I'm not one, I just enjoy learning from them - Thus I lurk here). If not for them we would still be living in caves. If something is even close to the realm of possibility these guys could do it. And they often accomplish what us lesser dudes think impossible.

Cheers

I'd be considering guest's as a far easier system to realise than the one I have seen (and attempted to draw).

So long as you could get the back rack to slide back into place somehow - elastic straps (called okky straps here - you probably have a different name for them) spring to mind - no pun intended. The elastic things with hooks on each end used to tie down a load on a car trailer.

Nice drawing Robert.

However, I think the cable/pulley idea such as Guest suggested better suits what I had in mind.

Thanks,

-John

I saw the design described in #1 at a home and remodeling show last month. I did take a brochure from the company. I will try to get the info back to you. I will not be able to access it till after weekend. BUT.

I do like the cable idea. If the cable-pulley will work on the horizontal plane, it should work in the vertical plane. Why not store that crap in the basement? Multiple slide out tracks would allow you to pull out the contents of the cabinet, then continue pulling and you could retrieve valuable items stored below. An appropriate sized hole in the floor under the cabinet, and you have doubled your cabinet storage space, without any additional floor space. There wasn't anything on the ceiling of the basement anyway. Please note. If you live in an appartment... never-mind.

As it turns out my wife manages a cabinetry showroom and designs kitchens.

Your arrangement is called a blind corner.

What you are looking for we call a half moon pull out.

One of the better manufactures is "Rev-a-shelf"

I think they call it a pull out blind corner kit. http://www.rev-a-shelf.com/

There are also pictures at the Woodmode website.

A Mail order supply company called "Lee Valley" sells these units as well. They are excellent! Lee Valley is also one of the best tool suppliers, with high quality and reasonable prices!

Hi Guest,

That looks more like what I'm looking for. I'll check in to this one.

Thanks much

Thanks Paddler,

But for $926.00 I think I can build a pretty good one.

I do appreciate the link though.
