I continued to update my Auto CAD model and I started to document and capture the past versions of the model for my journal.

This is my first design, it utilizes the sunroof and cartage design. the piston that pushed the carnage forward, up a ramp would also compress a set of arms that would lift the back of the platform to be flush with the deck. The issue with this design is that it would rely solely on the strength and integrity of the piston for structural support, meaning a single point of failure could compromise the stage.

This is the dissection of the 4 steel bar window hinge that I found in a catalog. The arms of the hinge are each have 3 points of constraint to create 1 compound axis of movement.

I wanted to extend an bar to be perpendicular and flush to the bottom of my platform. A leg extending from the  foundation to the hatch would provide significant support vertical compression and not rely on the piston for structural support when in position.

The next draft used the scissor lift idea but got rid of the ramp because it would not work with a single point hinge and kept inverting the platform. This design has four legs and would use cross bars to move the legs simultaneously.

This was reformed into the current design that uses a 2 part ramp to lift the stage to a preset level and then a vertical lift that moves the platform level with the deck as the legs are set into a vertical position.

Fighting with open lab to publish scans is challenging.

PDF’s do not show up as images so I need to save them as images, reformat them to 16bit color, then convert them into jpeg files because bitmap and XPS are insecure formats.
