I have so many ideas like this every day, that letting a few ideas out to ge some feedback is'nt such a bad thing.
just testin the waters.
plus, even after patetents, an idea like this would be such a versitle product, that anyone trying to duplicate the idea, still won't use the specific design that i've developed.
and that always leaves you with the best design and marketer winning the game. ($$$$$$$$$$$$$$)
i'll post some pics if I ever have the time to assemble and patent my design.
