I spent Father’s day bonding with my youngest son who is the father to my 2 grandchildren.
The goal was to build a structure to hold 2 (possibly 3 in the future) flat panel computer displays as well as a laptop computer from the back edge of a desk with the smallest footprint. The adjustments had to be tool-less.
We first set out to design it in Sketch Up and came up with 3 versions—each improving on the previous. The last one is the one we built.
The main structure was the backbone that everything would hang on.
The holes in the front are to route cables and cords.
This backbone is clamped to the back edge of a desk. In this photo shoot we used our dining table to simulate a desk. For the clamp we used a small 1/2 inch pipe clamp with a short piece of 1/2 inch black pipe.
Then the vertebra (adjustable modules) were built that used a 1/2” dowel that hooked into the notches on the back of the backbone. When the vertebra is tilted at about a 45 degree angle the module has enough clearance to move up and down on the backbone.
To each vertebra is attached a horizontal mounting bar with holes to which articulating links are attached (one for each flat panel display or laptop holder).
The monitor holder was wider than the holder for the laptop computer because of the width of each flat panel computer display.
If the articulating links look familiar, I used them when I built the dust collector for my drill press.
When the vertebra is at the desired height, the 1/2 inch dowel in placed in the notch and rotated down to lock in place.
This is what it looks like when in the full down position.
This is a look at the underside of each vertebra module that holds the monitors. The articulating arms are attached with wing nuts to each other; to the monitor Video Electronics Standards Association (VESA) plates; and to the horizontal mounting bar.
View form the back left.
At the end of each articulating arm is attached a block through which 4 screws are used to attach to the VESA – Flat Display Mounting Interface (FDMI) mounting holes on the back of each flat panel display.
Another view from the back right.
A laptop computer holder is attached to the end of one articulated arm.
What’s nice about this system is that Each articulating arm can be made as long or as short as required.
This is the view from the front with 2 flat panel displays and the laptop computer holder.
The next version (or additions to this one) will include vertical legs that will help with the slight sagging observed when this was tested.
Hope you enjoyed reading about this project. Maybe you have a situation that this idea would be applicable.
Comments are encouraged and questions are welcomed.
Thanks for looking.
