A simple padlock inspired me to reinvent a novel method for securing personal property or other items. Traditional padlocks include a U-shaped shackle.
However, there are situations or applications where a U-shaped shackle may be unsuitable. Accordingly, what is need are improved shackles capable of securing items that are not well suited to traditional shackles.

I have 41 other ingeniously new patentable key or keyless functionally/mechanically unique, obvious, hack, bump resistant locking padlocks and locking devices for consumer products.  Many can be product bundled using any padlock.

Each of my 41 patentable padlock working prototypes are functionally/mechanically unique meaning not for differences or uses of colors, computer chips, cores, cosmetic, decorative, design changes, dial combination configurations, dimensions, disc/pin/wafer tumblers, engraving, fasteners, graphics, illumination mechanism, images, insulated cover, keypad, keyways, lamellae, letters, metal composition, method of manufacturing, no use of plastics, non-functional anything, numbers, ornamental modifications, outer cover, outer sleeve, padlock jacket, photos, power supply, protective cover, rivets, roll pins, rubber, shackle sides, shield, shroud size, textures, thin padlock walls, timer, unique keys, visual and no built in analog or digital clock showing local time.

Mon, 13 Dec 2010   Oh my god!!!  This lock is the BEST!!!  You should market it. 
Thank you so much!  Can I get another one?  Maybe 2 more?  I'll pay for them this time!  Such a smart design.  I'm impressed.
Sat, 14 Nov 2009 Dear Padlock inventor, I too have recently looked at the padlock patents and it is indeed pathetic what the conventional companies continue to sell.
Tue, 02 Sep 2008 I have to admit that those shackles certainly seem very similar to me, but the threshold of "novelty" for design patents is pretty low. There's no functional difference between a lock with a round shackle and one with an octagonal cross-section - but functional difference is exactly what design patents are NOT intended to protect. Clearly, a round shackle is different visually from one with eight sides, and perhaps that's a difference which means something to a padlock manufacturer. Or, more likely, they hope that it will distinguish their goods from their competitors', so that a consumer will see a lock with an eight-sided shackle hanging on a rack with all the round-shackled locks and say, "I like that company's locks, so I'll buy that one." It's not unlike the differences in design of keys for locks - the punched rectangular top doesn't work any better than a round one, but it makes it instantly recognizable as a Kwikset. (Design patent and trade dress/product configuration protection kind of overlap, here) Design patents have their place in the general scheme of protection, but there's a reason why they're less expensive, shorter lived, and easier to get. They just cover a visual difference from what was done before, and for some people, that's enough.
