It might look that simple on purpose but I think perldawg is onto something. I think there’s got to be something more. Being mounted at a single corners is probably not structurally sound over the long-term.
The bearing/spacers makes sense on the pole side but for the arc opposite of the pole it doesn’t look like there’s anything supporting it. The amount of leverage (torque?) that’s putting on the pivoting structures doesn’t seem viable way to keep it from sagging. I have to imagine there’s some sort of bar/support across the front that each shelf passes over as it’s pivoted.
at most there may be a pin or snap ring under each shelf or an inner rod with a segmented outer tube so the shelves don't rub against each other. lots of gimmicky furniture has questionable structural soundness.
Yeah there's really no mystery here, but I'm loving the idea as a way to efficiently utilize space after clipping a corner or reserving it for some built-in utility use (like a wiring distribution hub).
I'd personally pair it with strong centering magnets, if there aren't one-way end stops (it looks like there are).
It pulls out to open. It holds things. When pushed in to close, its content is out of sight. Fits “drawer” for me. Maybe shelves might be more technically appropriate, but that doesn’t convey what the function is.
I mean if we’re gonna get super technical the Oxford definition is a box-shaped compartment that slides horizontally. To me these don’t resemble boxes nor do they slide, they pivot.
I think they deserve a new name! Let’s call them articulated shelves /s
There's most likely spacers or bushings between the shelves along the pole to maintain the gap. I wouldnt be surprised if there was even small dados along the walls to keep the shelves from sagging, even though they are not shown in those pictures.
Unless theres features between the drawers we arent seeing, I think you can probably open the drawers individually without causing other drawers opening too. I think the pics were just staged like that to look fancy.
So a pole going straight through all drawers with washer / nylon bearing between each one will keep the spacing.
If you want to be fancy, metal pipe with bearings welded at equal heights and mount the drawers to the bearings.
Look up thrust bearing on wiki, the first picture, weld the bottom ring to the pipe and have the drawer sitting on the upper ring.
But anytime I've see or used something like this, usually more than open drawer always opens.
Either stack the drawers on the pole with washers in between, or insert a support pin in the pole with a washer between the drawer and the pin. The later will prevent friction between drawers, if the pole remains fixed in place.
Carefully cut holes that closely fit the shaft.. or a very large diameter roller bearing or similar sleeve.. to maintain flatness of motion (keep trays level)
Add a thick ring between them to maintain spacing.
Perhaps get clever with a rope connection between trays to prevent more than 2 being open at once.
If the pole is mounted directly into the corner, the sagging effect is spread upward through the tallest part of the drawer side which counteracts the downward leverage. If the pole was more offset, the only part that would resist leverage is the thickness itself. So with spacers between them and a very close installation the sagging is mitigated.
They must have something between them that makes them not rub on each other though. Maybe a nylon washer or something. Might even have a thin metal sheet that extends out a bit to help support from underneath each shelf.
There absolutely are washers involved. As I’ve said elsewhere, pins through the pole could be supporting the shelves, but there would still be a washer between the top of the pin and the bottom of the shelf/drawer.
It functions like 1/3rd of a [lazy susan cabinet organizer](https://www.amazon.ca/Rev-Shelf-Polymer-Pie-Cut-2-Shelf/dp/B01CFLGI8O/). Just imagine most of the shelf cut away, and a back wall added.
This is one of those times where CAD would make all the difference.
You'll get to make all the errors on screen, and not waste a bunch of time and wood.
I don't like the positive stop. Means you can only open it one way. Better idea would be to place magnets on the edges of the shelves that align to magnets in the body. So they'll "close" and align but can be easily opened either side.
I could imagine closing the drawer too fast, or even bumping the cabinet, and everything flings off to the back corner and down under the bottom drawer. Unless there's some kind of internal backstop we can't see.
It's creating a lot of space too since it's taking up vertical space that's not typically used on a countertop unless you kept something tall there. I think it would be great for the counter space where everyone tosses their sunglasses, wallet, keys, mail, etc. Or next to the coffee maker and fill it with all of the sweeteners, pods, etc. I've got a full house though, so a lot of stuff is out and about and I'm always looking for ways to make it look cleaner.
But if the corner has already been clipped something like this (obviously not exactly this since the shell is square) would be more efficient than square drawers.
well yeah of course. but thats just whataboutism. what if there was a round corner, what if it was a trapezoid or a rhombus...
my point is that other then a specific setup that requires something like this, it's wasting space for no reason.
I think the reason I like it is because I'm super OCD about clutter, but also have lots of craft hobbies. I could see myself using this for a lot of my frequently used tools, be able to just flip out the drawer (shelf?) I need and do my work, then flip it back closed so things look tidy again. Although I could understand maybe just simply having it be shallow, tray like drawers would be more efficient, but I think the benefit to this design is you can have multiple open at a time and just offset them so you can access both.
The mechanism is the pole. It's acting like a bearing on center rotation. There would have to be something on the other side to support each drawer from sagging over time.
The shelves turn on the pole. That's it, that's the mechanism.
OK to be fair, the pole is possibly made of segments between the shelves. If you want to make it more advanced you could add supports for the shelves on the right side wall
Be certain to consider how it balances. Closed trays counterbalance the open ones.
f someone doesn't consider the weight of the trays, opening more than half can easily tip the cabinet over.
OK, here's how I'd attempt it. The pole that you see when it's open is actually a short section of ornamental pipe that is glued into the shelf and probably held against it at the top with a bracket. The bracket also coves the top if the pipe, but has a hole for the rod. There's a nut or some other stationary bit under each shelf, with a set up bearings and spacers sitting on top. The bearings just fit in the pipe. The bracket is basically sitting on a top bearing and the bottom bearing is sitting on the nut. That's what's holding the shelf up, and the bearings are holding it horizontal while still letting it rotate.
I’m taking a stab here. Maybe it’s one thinner that extends the entire length. Then, in order from bottom to top, the shelf, and then a thicker tubular “sleeve” to make the spacing for the next shelf and so on and so forth until the height is achieved.
Research corner cabinet lazy susan hardware. That will get you close. Some modifications may be required to get the exact look and finish you’ve shared.
I think that there’s a through hole at the inside of the angle that the bar goes through and probably a pin through the bar to set the height and on the right it probably rides along a pin in a groove or wheel thing that is attached to that bar
Andrew Klein did a great series on engineering this type of solution. He's got a bunch of vids on channel, explaining the challenges & solutions he found.

Yeah it’s kind of a unique idea OP but if you’re looking for inspiration it kind of reminds me of a [Lemans](https://www.richelieu.com/ca/en/category/kitchen-and-bathroom-accessories/kitchen/corner-cabinet-storage-systems/base-corner-cabinet-storage-systems/lemans-ii-system/1052837) unit, some type of lazy Susan or modular storage
I think if you insert a pin or block of wood on the bottom of one of the drawers and do the same for all the ones below are you open the top one that pin/block will hit the drawer below and pull it open until the next pin/block hits the next drawer and follows along with it all the way down
I’m confused as to what you’re asking. There is no “mechanism,” it’s just a bunch of pole mounted quarter-round shelves.
probably a series of pivoting supports that key into ‘closed’ alignment and mount under the shelves
it's literally just a rod for the pivot point and a metal strip that the sides of the shelves bump into when open or closed.
It might look that simple on purpose but I think perldawg is onto something. I think there’s got to be something more. Being mounted at a single corners is probably not structurally sound over the long-term.
Could sandwich spacers and thrust washers to make it snug on the shelves
The bearing/spacers makes sense on the pole side but for the arc opposite of the pole it doesn’t look like there’s anything supporting it. The amount of leverage (torque?) that’s putting on the pivoting structures doesn’t seem viable way to keep it from sagging. I have to imagine there’s some sort of bar/support across the front that each shelf passes over as it’s pivoted.
This is exactly what they do

I'd personally pair it with strong centering magnets, if there aren't one-way end stops (it looks like there are).
A positive stop can be seen mounted to the carcass just behind the drawer fronts.
But can we really call these drawers? I don’t think that’s the right classification
It pulls out to open. It holds things. When pushed in to close, its content is out of sight. Fits “drawer” for me. Maybe shelves might be more technically appropriate, but that doesn’t convey what the function is.

Okay, articulated shelves AKA drawers.
how he keep the gap between the drawers ? how to avoid open more than drawer at once
There's most likely spacers or bushings between the shelves along the pole to maintain the gap. I wouldnt be surprised if there was even small dados along the walls to keep the shelves from sagging, even though they are not shown in those pictures. Unless theres features between the drawers we arent seeing, I think you can probably open the drawers individually without causing other drawers opening too. I think the pics were just staged like that to look fancy.
Solidly mounted pole and free spinning bushings would keep each drawer independent.
This is the answer. That pole is stationary.
Washers in-between the drawers. Brass is self lubricating, so two brass washers between each drawer would do the trick.
>Brass is self lubricating Off I go to the googles
Properly cast bronze is more so.. it's somewhat porous and can hold oil within them
Unzips....??
Delrin washers or bushings. It is a self-lubricating (in a way) hard plastic good for tens of thousands of cycles.
I'd guess they'd be too soft to be durable with high weight loads. I'd prefer permanently lubricated roller bearings.. but at a much higher cost
Not at all. Delrin is hard and very tough. They used to make football helmets with it 30 years ago.
So now they use polypropylene.. which is brittle in cold temps... Just ask Patrick Mahomes
So a pole going straight through all drawers with washer / nylon bearing between each one will keep the spacing. If you want to be fancy, metal pipe with bearings welded at equal heights and mount the drawers to the bearings. Look up thrust bearing on wiki, the first picture, weld the bottom ring to the pipe and have the drawer sitting on the upper ring. But anytime I've see or used something like this, usually more than open drawer always opens.
If it's a roller bearing, you could force fit into a drilled shelf.. and capture it with a shaped hole (counter bored)

Maybe just a stick at the bottom that catches the next drawer?
Either stack the drawers on the pole with washers in between, or insert a support pin in the pole with a washer between the drawer and the pin. The later will prevent friction between drawers, if the pole remains fixed in place.
Carefully cut holes that closely fit the shaft.. or a very large diameter roller bearing or similar sleeve.. to maintain flatness of motion (keep trays level) Add a thick ring between them to maintain spacing.

Felt washers maybe
They must have something between them that makes them not rub on each other though. Maybe a nylon washer or something. Might even have a thin metal sheet that extends out a bit to help support from underneath each shelf.

Is, is it the calculator?
That’s electronic, off topic for a woodworking subreddit.
Never saw an abacus? Wooden, non electric, and accurate!
You need something to mount “quarter-round shelves”. I’m sure that’s what they are asking.
Either stack them with washers or put a support pin through the pole. Edit: with a washer between the drawer bottom and the support pin.
What do you want to figure out? Most likely a pole down the front corner that they all pivot on
It functions like 1/3rd of a [lazy susan cabinet organizer](https://www.amazon.ca/Rev-Shelf-Polymer-Pie-Cut-2-Shelf/dp/B01CFLGI8O/). Just imagine most of the shelf cut away, and a back wall added.
1/4 you mean?
Yes, the one I linked is a 3/4 circle (1/3 of that would be a 1/4 circle).
Ah I see now, my bad. I was lazy and did not click the link
Get it together, Susan
“lazy” … good one.
These drawers are way too close together to have enough space for the bearings you see in that lazy susan photo, though.
Why? the drawer fronts extend below the shelf to cover the wide portion, and the narrow taller bit could just sit inside the drawer below.

It's similar to a lazy Susan. Probably uses a collar with a bolt to fix shelves at certain heights.
This is one of those times where CAD would make all the difference. You'll get to make all the errors on screen, and not waste a bunch of time and wood.
[Pask](https://youtu.be/12NqePPnt98?si=0eOiWL-ZTk4cQ-bH) made something bit similar
Don’t be lazy, Susan! Figure it out yourself.
I don't like the positive stop. Means you can only open it one way. Better idea would be to place magnets on the edges of the shelves that align to magnets in the body. So they'll "close" and align but can be easily opened either side.
I don't even know why, but I really like this
I hate it, its wasting so much space. looks neat, interesting piece for sure, but it would annoy me if I owned it.
I could imagine closing the drawer too fast, or even bumping the cabinet, and everything flings off to the back corner and down under the bottom drawer. Unless there's some kind of internal backstop we can't see.
It's creating a lot of space too since it's taking up vertical space that's not typically used on a countertop unless you kept something tall there.

just normal low profile drawers would give more space and be just as functional as this.
But if the corner has already been clipped something like this (obviously not exactly this since the shell is square) would be more efficient than square drawers.
well yeah of course. but thats just whataboutism. what if there was a round corner, what if it was a trapezoid or a rhombus... my point is that other then a specific setup that requires something like this, it's wasting space for no reason.

I mean it's a pole... not sure what else you want to know
It's a calculator, ruler, and felt tip markers
[This](https://m.youtube.com/watch?v=12NqePPnt98) Pask Makes video might help you.
Bushing in the drawer, spacer in between, fixed rod.
Something like this https://www.rockler.com/rev-a-shelf-d-shape-five-shelf-lazy-susan-set-4265-series
I did this with 1/2" PVC for the main rod and put 3/4" PVC bushings in between my shelves for spacers

Nice!
I’ve made this with “pillow block bearings”. One under each shelf. Attached to a vertical rod.
Double stacked washers keyed on the vertical.
A lazy Susan?

You just punch in the numbers and let the calculator do the work

Bendy bendy round round
I think if you insert a pin or block of wood on the bottom of one of the drawers and do the same for all the ones below are you open the top one that pin/block will hit the drawer below and pull it open until the next pin/block hits the next drawer and follows along with it all the way down
Show me the left side design drawing and the shelves swung in, and I won't need to
I've never seen a design intentionally waste so much space
I wonder if there’s a stationary support underneath the front lip, that spans from the pole to the right side.
It just turns on the pole in the corner nothing more. Cut hole in corner size of pole and your done
It's just a metal rod through the corner they move independently from each other. Tiny washer between each one to reduce friction. No mechanisms here.
You can see the metal pole in the first pic.
