Linear actuator door opener

This was done for a ceiling cabinet with a projector many years ago.
The 3d printed brackets have yellow screws to reinforce them, the big screw holding the linear actuator goes right through the side of the cabinet with a wing nut attached, so in case of malfunction it is possible to open the cabinet by simply unscrewing the wing nut and pushing the long screw through the side and the bigger bracket.

thanks for sharing sir ❤️🙏🏻🙏🏻

I'm interested to implement this linear actuator to my cabinet 😁

I found this great. Wondering if you can do up a simple drawing of this same thing in a recliner position with a vertical to flat motion. ( 90 degrees )I am looking to build some power recliners in a more custom way rather than the stuff sold these days.
This diagram and video are almost 100% what I am looking for.
I am trying for independent back rest and foot rest. The frame would be solid wood and not springs with upholstery attached.

thanks very much- Particularly appreciate the quick response.

hey where did you get the linear actuator from and the hinges and brackets i am doing the same type of engineering but on a mail box door

[antonfelich]

Love it! This is exactly what I need, you don't happen to have the STL or SCAD files handy so I can print the brackets?

¿ Ha utilizado los actuadores lineales para elevar (abrir) puertas basculantes de garaje ?

can somebody tell about the mechanism, how the motor extends the telescopic boom??

[mdspine]

Igor- I forgot to ask. Are those soft close 135 deg hinges? I would think I cannot get away with the soft close as the actuator will pull the hinge closed even if resisted. thanks in advance!

What is the stroke length on this actuator? Thinking about doing a similar project

[chrishorn]

Hello. I'm working on a robotics project. We are debating whether to use solenoids or actuators. Regarding the above process you created: How did you calculate the actuators necessary mm needed to open the door 90 degrees?

[darkphoenix]

Hi, do you know how to increase the speed of the actuator?

[ovalwingnut]

That must be on the Space Shuttle's door, yes? If not it some serious "over kill". But a GR8T job none the less :O)

[vijaykumarsubramanian]

What will happen if the motor in the linear actuator gets stuck up or broken?
This will necessitate breaking the door and cupboard.

I'm new to actuators - can you give some basic info?  It appears that when power is first applied, the actuator goes to its full limit and stays; then another power signal is sent and it retracts.  Is that right?  I'm trying to come up with a device that will open a door when it get a signal from a timer, then when the other timer goes off it retracts.  What I'm afraid of is that when the power goes off from the first timer, it automatically retracts.

how do you control it when it goes out and in?

[pedropereira]

Hi there! Interested in your design! (Door opener with actuator). Struggling to do the drawing to calculate the actuator stroke...Can you share your design please? Thanks

[mohsenhosamo]

Hi, please what is the name of the mounting brackets and where i can buy them? thanks

[Gorilla_Jones]

What is the stroke needed for a 90 degree pivot?

[MrGardenRoute]

Excellent solution!
I'm looking something like this for my Domotica project of "Robotic vacuum cleaner dock" in kitchen, it is possible to buy somewhere?

Igor - Thanks for sharing,
I have exactly same plane for opening small door for projector,
Q - How can i trigger for open closing the actuator by RF?
Scenario :
I have some RF box which connected to the projector(220V),
When i press on Projector On/Off button it sends RF signal to the projector screen for opening / closing it
So i need somehow component that be connected to the actuators and will get the RF signals from the box and it open/close the door.
Can some1 help?
