The system is comprised of
- cylinders (hubs)
- struts (rectangular section steel, aluminium, acrylic or other )
- jaws ( 4 x same shape - two with slot for compression spring and two with hole for small pin to compress spring)
- high tensile bolts
- nylock nuts ( have explored quick release fasteners i.e bicycle wheel skewers etc )
- fail safe jaw washers
- hub centre eye bolt (for rigging/hanging)
I designed this configuration to employ minimal manufacturing processes, it is laser or plasma cut (found laser provided a smoother surface finish) . The first prototype was originally create by the camp fire in the bush with basic hand tools .
The concept was the extrapolated , to a much more sophisticated and expensive design, prototype was 'grown' via optical fabrication in liquid ultraviolet curable photopolymer "resin" was to then be manufactured from injection moulded Nylon6 .
modelled around 'handcuffs' and 'hose fittings' ...
financial and other personal issues halted the project there ...
that was about 8 or so years ago ...
