There is a program for windows called Linkage that I’ve used to tweak straight line generators, and I’m fairly sure this would be easy to replicate. The upper left link seems to be attached at the midpoint of the lower left one and is half its length. The lower right one looks like it’s the same length as the lower left one. I’m not sure that the joining link length really matters. The overall linkage probably has a name but I’ve no idea what it is.
Thanks for your reply... But if I am not mechanical engr,,, and I saw any of your post in past and I need it in future to refer someone, how I can search? If any reference number is there, it could be searched easily...
You can make this in any CAD software. I suspect this is Fusion 360 though it could be something else, they're all basically the same in terms of the end result.
In this case I think it's just the simulation. It would extend a bit further, then possibly be stuck if the rotational force stopped at the full extension of the right linkages.
A=distance between legs (vertical part) of PI B=distance between ankers on base horizontal C=green and yellow lines are same D=orange line E=blue line F=horizontal part of PI leg G=distance between leg and anker vertical A=B/4 or E/2 B=4A or E + 2A or 2E C^2=B^2 + 3A^2 (pitagora) D=C/2 E=2A or B/2 F=A G=B I am not a mathematician,this is just by logic and i might be wrong,if i am please let me know.
Curious little construction, however, it would seem it doesn't deliver on it's promises, at least I cannot get it to do so, although I can get to within .25% of the base distance, in terms og keeping the platform at the same height.
I operate a scissor lift everyday and we already have a side to side movement, simply drive forward or backwards and then the platform extends as well at the top. Now if this was facing the opposite direction of the wheels , maybee but then again it's already pretty easy to get wherever you need to go because the wheels turn on a dime but I can think of a few places where this might have been nice to have, due to step hills but that's not very often
@@user-jd4lc5fu4p ну и что? древняя подвеска мерседес w124 имеет 36 шарниров на одну только заднюю подвеску!!! и имеет слабыми всего два шарнира - шаровые сайлентблоки, которые тоже неслабо бегают, аж целых 200000 км!!! минимум!

Tchebycheff or Chebyshev's 'engineers table.' It's a very good approximation to a straight line motion with an added link to give a parallel motion.

When the π want to make use of a straight line than a circle
π in this case, is using 2 circles to make a straight line

The oscillation of each pivot is still represented by a period. Pi is inescapable.

With the PiSlider 9000 you can move your Pi to the left or right; or anywhere between.

I LOVE it. But plz add any serial number OR particular name to help in search it again.
Yes, PLEASE
As you r a mechanical engineer, you can understand by simply seeing the linkage system
Thanks for your reply...

@@GeetS4 ok, if u r thinking otherwise, I will ask u sorry.
LOVE You Dear ... Bye with thanks.
Yellow and Green = equal length
Red = Yellow length / 2
BasePlate pivot distance = Yellow length / 1,25
Blue length = BasePlate pivot distance /2
TopPlate pivot distance = Blue length
Thanks, I wasn’t having any luck finding these ratios.
gracias
You have no idea how helpful this was
Ah, just the mechanism I needed for my pi perambulator.
I hate it when people post these cool things and not show the program that it was made in
You can make this in any CAD software.
I suspect this is Fusion 360 though it could be something else, they're all basically the same in terms of the end result.
Apparently there’s a free linkage app called Linkage. Haven’t tried it - only have watched a tutorial.
Moving platform in a straight line with linkage system- simple and super design.
Scrapman when he saw this: Awh yep
I'm here for similar reasons 😂
When adding weight makes the table move sideways instead of down
No, weight won't make it move at all
@@danielfearn6076 it does, but the force from the ground collision cancels it off
Um... isn't the table already moving sideways, not down?
@@danielfearn6076 Only when it's enough to crush it! :)
sounds like a good shoe
I’d imagine that would fall apart very easily
Oh Gosh, I so was searching for something like this ! Thanks !
Nice! I would love to see components with consistent length ratios to one another labeled and the ratio listed.
I usually don't like music in mechanical videos but I have to admit the pi chair is absolutely vibing along so it's ok

Similar principles are used on mtb rear swing arm. i think
This is awesome, i wonder if this can be slimmer

what is stopping it from leaning on left side?
In this case I think it's just the simulation. It would extend a bit further, then possibly be stuck if the rotational force stopped at the full extension of the right linkages.
That really mechanics my principles

This is how platforms in Mario work
I have gained the knowledge of machinable pineapples
I wanna make one in solidworks. Do you have a tutorial?)
Curious little construction, however, it would seem it doesn't deliver on it's promises, at least I cannot get it to do so, although I can get to within .25% of the base distance, in terms og keeping the platform at the same height.
I operate a scissor lift everyday and we already have a side to side movement, simply drive forward or backwards and then the platform extends as well at the top. Now if this was facing the opposite direction of the wheels , maybee but then again it's already pretty easy to get wherever you need to go because the wheels turn on a dime but I can think of a few places where this might have been nice to have, due to step hills but that's not very often
