design padlock

[Gengis26]

I should design a bicycle pad from the conceptual point of view.
I can't find anyone on the internet.

I would need to better understand the internal mechanism and the calculations necessary for a maximum design.

Thank you in advance for your help!

the integrated locks of the old bikes are very simple objects.http://www.google.it/search?q=lucch...pgnfktcgaassyeg&start=100&sa=n#mhpiv=10&spf=5Basically you have the key lock that lets out/enter a pile on the track to u.
the female u track contains a slider with a handle (closes and opens the missing ring).
when you pull down the lever drill the wheel that can no longer turn and turning the lock does not return the bolt and then remains stuck.

It can't work so different.
Last time I was 8 years old and it was a 50-year-old bicycle... .
