    Default The hinge linkage for "The Coffin" on my trailer

    The previous box on my trailer was hastily made from plywood one year before a December holiday.

    I knew that was not permanent, but at that time I had little choce.

    I now had a box made up from a light angle iron framed and cladded with Aluminium Checkered plate.


    I did not want straight hinges, as the problem with that is that it usually damage the sealing rubber over time.

    This linkage in effect puts the lid down from the top so that it does not rub the seals, and secondly, I had to make it go over the side in order to miss the external cage of the trailer.

    The linkage was designed on a link simulator and works very well. Perfectly balanced one can open an close it with the palm of your hand up or down.


    Now I can have all the camping goodies like the tent, stretchers and chairs safely kept in the trailer, locked, water tight and no entry for vermin.

    Something I should have done a long time ago..

    Perfect. Well done. Just one thing, Turn the gas strut upside down to ensure internal lubrication.
    What simulator did you use?
