Unbrella - unbreakable brella

Works by pull instead of push

Four or five sun shade rings (the metal ring that folds or flips back into position) are hooked together and are held in place and prevented from opening by chords attached to the umbrella rod. These tension chords replace the umbrella spikes.

There's no way this umbrella can turn upside down, and it lasts for years although cheaper to make than a standard umbrella and much less parts.

this is with a single "sun shade" rim. Would be better if several together in a flower shape [pashute, Apr 02 2016]

       I think a diagram might help here.

       But then you have all the cords in your face when you use the unbrella, which is (probably) the precise reason for the existing "compression" style framework.

       Not necessarily. They can be in the upper part where the spikes are today.   

       Yesterday we had a muddy end of dust-storm rain. We saw a woman running in high-heeled shoes then standing at a red light and crossing the road without noticing her overturned umbrella. My phone takes ages to bring on the camera, so I missed the chance to take a picture.
