- Yellow movable plate is fixed to green connecting rod of the linkage.
Red spring holds the movable plate at stretching or folding positions.

This specific thing is exactly what I wanted to see when I went on to youtube today. That is all
You're welcome.
Ah yes, the finger pincher 3000. Double the finger pinches or your digits back.
Seriously? This is clearly a Finger Pincher 6000, its even got the "only closes the door in one of its two positions" package
remember, someone with great difficulty finding ideas, respect the inventors by not exposing them too much
The perfect mechanism for my trapdoor welcome mat. Looking forward to less solicitors. Thanx!
This spring must be very strong. And this part of table can hold only a low weight. I guess, here must be a some locking mechanism or folding legs.
I like this design for the upper cabinets I have in my camping van. The cabinet is only 5 inches tall, and I don't like having a lip to keep stuff in... since stuff keeps falling down. I just gotta draw this pattern and cut my own with plasma!
It's a door. Or it should be, i think? It's really weirdly anchored on those planks... Definitely would be a horrible table
You can already buy these types of hinges from Blum and other companies. And some of them include soft close and other handy features.
Gotta admit I’ve never seen one of these on a table. Only cabinets like the first commenter described.
@@fearofchicke I don't know where the table conversation came in. I was also thinking of cabinets
This is the third hinge videos I watched today, idk what UA-cam is trying to tell me
The algorithm is finally getting it right
Nice and useful mechanic design.
It's 1 am and I really need to watch this 90 deg. hinge
Awesome mechanisms; everyone should have them.
I can already feel the slack in it after using it for a week. Those tolerance's are not staying for long with that design, granted in theory its cool. Maybe beef it up a bit.
I like this 90 degree stop design much better.
My mother had a small sewing table with this mechanism raising the extension.
Another day, another random video that got recommended.
I love this one
Спасибо, это интересно
Gracias por compartir tus Diseños
Basically our german door hinges we have for wardrobes or kitchen cabinet doors. Just less elegant and reused as a table extension.
the spring could be isolated inside 2 sliding cylinders. for safety and duration
Yes.
Thank you for your idea.
OMG, cool!!
Very nice
хороший столик!
A pneumatic cylinder will b installed to blue or pink bar with u.clamp fitting
To the pink bar not to the blue bar.
¡Genial! el mecanismo que necesito..
Хороший механизм для стол-книжки
а мне непонятно, за счет чего он будет держать усилие на закрытие...
@@averlina1498 только за счёт пружины , однако )
И упадёт с нагрузкой🤔, не понимаю зачем мне это без фиксатора...
Thank you.
No problem
Wooooooooooooooooooooooow
How quickly will it break?
now i know how my kitchen table works
Nice
Wow! How do you even begin to design these? Link lengths? All that?
I guess it all starts by analyzing the moving part (green). You already know the starting and ending position and orientation of it, and you know it should have 2 links to describe that movement. Then you need to trace a circle that touches a given anchor point at its initial and ending positions.... and there you have the first link origin and length (circle's origin's point and radius). then do the same with the other anchor point, and you have the other link origin and length. Then you repeat the same thing over and over with different origins and lengths, and you end up "getting it" how anchor point's position and link length affects the motion... I guess it's not intuitive until you test it.. .maybe there's a more mathematical way to design it, but I usually do the trial-error way
@@radiowallofsound Thank you for the reply!
To meet the desired closed and open positions of the movable
plate, “try and adjust” is the method used here.
With a CAD software that can support kinetic simulation the process is less laborious.
It means that we have to alter dimensions of the bars, run the simulation and check the movable positions for each case until getting desired result.
Become a mechanical engineer and take few extra courses on kinematics... Also dont be a dumbass, they can't do much about that in school.

Nice. This uses over-center mechanism with the spring, right?
Yes.
@@thang010146do you have any ideas how the spring pulling force could be damped for smoother movement at end of motion?
@@charliebucket
Please refer to
ua-cam.com/video/KU4JKCrpjGw/v-deo.html
The inner space of the green cylinder is closed and filled with oil (or air). On the yellow piston there are small holes for oil to pass through, so the oil has the effect of reducing spring force.
What software do you use to simulate mechanisms?
All videos in this channel are made in Autodesk Inventor, Dynamic Simulation.
How can i learn to design them. Not to model in 3d software, but to get yhe idea of linkage synthesis as per my requirement
Your question is very difficult for me to answer because it involves a long issue.
Good
Does anyone know of a similar mechanism that uses fewer parts (here 4 + spring)?
It'a difficult to consider movments with less than 4 parts
If there were three, each link wouldnt be able to move in a triangle position(the foundation behind truss structures)
And 2 is just a pivot lol
The mechanism is too complex. Lots of moving parts. And it will move to the left and to the right. You can solve it with a simple door hinge.
But it might not stay
Mr Thang, how strong the spring has to be?
At least it must be strong enough to bear the desk weight.
Pog!
1. Need locking mechanism to keep in deployed position. 2. Using springs is a large pinching hazard, design featuring this would not pass risk assessment if it is to be a consumer product.
No lock in that... If a heavy thing put at the edge then it will collapse
Yes. You are right.
How did u make the spring in inventor? In the assemble there is only spring ends.
The spring is created in Dynamic Simulation, so there is no need to create the spring body.
can you tell me what the program you are using for these examples -

@@thang010146 thank you
Won't hold a lot of weight. Might be better as a door.
i swear to god, if i see a comment that says "wHo eLsE goT tHis On thEiR rEcomMenDed??" im gonna lose my shit
you got this in your recommended too?

Underrated comment. Lmao
Famous. What do you use, Catia or solidwork?

Wouldn't it close if I push on it? I see some flaws
To close it use a strong enough force applied to the green part (larger than the spring force).

where would you buy a hinge like this?
Sorry, I don't know. I just animated it.
как фиксировать? мне кажется, должен быть разблокирующий рычаг
Positioning:
In folded position: the pink bar contacts the pin on the purple bracket.
In the extended position: the yellow plate is in contact with the upper plate of the table.
Can you show rocker bending punch mechanism

Hey what software do you use?

@@thang010146 does SOLIDWORKS have a similar tool, i have been trying find one, if you know of a simple one for making/studying mechanisms quickly?
I can not help you. I only know Autodesk Inventor.
Thangs3d is that your website?
No.
what's the spring's lever advantage once extended?
The spring holds the movable plate at stretching position.
Alternate the spring pivot position to get larger holding force.
@@thang010146 I worded that poorly.. what's the spring's force multiplier given the arrangement shown in the video? thx!
pero con peso ..no se retraerá??
No problem if the weight is fixed firmly to the yellow desk.
Who was sent here by your teachers? I did. 😂

Yes. It can bear only a small weight.
