The umbrella has 8 long metal arms that support the canopy, each itself supporten by two additional arms underneath. The canopy stretched above acts as the “skin” and the arms and the mechanism under it act as the “bones” of this system.

All joints are rotating pin joints, with the exception of the tip of the umbrella above the canopy and the handle, both of which are fixed joints.

The mechanism of the umbrella works as a spring loaded one, in that the spring once released from the clip below, pushes the arms upwards until they are in the position depicted in the drawing above.

The only thing stopping the pin joints from rotating too far is the 6cm stopper positioned on the rod, just under the centre of the canopy.
