    Would you mind doing a pictorial review of said rocker?

    I'm planning to make a 1/4 length/titanium/Spyderline/balsa-wood-handle UL version in the near future...

    Thanks!

    I was thinking about getting a cheap baby rocker and take the mechinism out and rig it to my hammock. The only thing stopping me is the clicking noise.
    With that much Jim, you shouldn't need anyone to rock you to sleep.

    Try using your walking stick to rock yourself.

    hi guys



    here is a rocking device which seems to work (at least for a bridge hammock)

    http://www.boatstogo.com/hammock-rocker-swing.asp

    i have an additional rough idea :

    1) same like the movie in the link above - a motor rotation, is converted to a Back and forth, horizontal movement ("tug Cycle"), of a "pulling lever", which Pull-Release, on a string, which is tied somehow to the hammock
    (or to a mattress under you.??)

    2) the tug occur with every swing cycle.

    3) Now here is the NEW suggested part:

    A) the string is going from the hammock, over a pulley, and is tied to a (minimal) weight, so this weight is going up and down, along with the hammock swinging back and forth)

    B) the tug is short, and faster then the swing speed, so every swing, it adds momentum , by temporarily locking on the string.

    C) And this is how: The string is running on top of a lever, that is held in place by a spring, from above.

    D) The tug initial increased friction (adds to the weight stretch), and forces that lever, to come down, until it catches, and, temporarily, locks the string between 2 friction surfaces (like a crocodile closes its mouth on the poor string, that was flowing freely through it, till now).

    E) As long as the crocodiles mouth is closed, this friction allows the tug, to be transferred to the string, and the hammock is pulled.

    E) The increased momentum of the swing, plus, the tug cycle ending, make the string loose enough for the lever to go back up, (by the pull of its spring), releasing the string from the "crocodile" friction.

    F) so the the string can continue to flow forth, and back, and forth, on the pulley, minimally stretched, between the hammock and the weight, until the next tug kicks in, to temporarily, close the crocodile mouth again, on the string, for another short pull.

    Sorry if it came out little complicated.

    i am not so good at these things.

    a drawing probably would have helped.

    To Summarize - it is a Lock and Release mechanism, triggered, some how, by the tug cycle, which allows the pull to be transferred to the string, for a brief moment.

    It is easy to understand the concept, when you rock in a hammock, and simulate the
    lock-release action, on the string, with your hand.

    (Actually, the horizontal speed of the "pulling lever", is continuously increasing, and decreasing.
    So if we look at the "Half Cycle", in which both hammock and "pulling lever", are moving in the same direction, we can see that, towards the middle of this half cycle, the increasing horizontal speed of the pulling lever will catch up, and start to exceed, that of the hammock, and that triggers, the "Lock-pull" part.

    Towards the end of this "Half Cycle", as the horizontal speed of the pulling lever, decrease, below that of the pulled hammock, the Locking lever, is released)



    Do you think it can work?

    Is it too complicated?

    I hope someone good at these things, will take it farther, and hopefully translate it to something useful, and practical.

    THE BOTTOM LINE IS:
    WE NEED THE OPTION TO FALL ASLEEP IN A SWINGING HAMMOCK !
    ITS OUR BIRTH RIGHT!

    On second thought :

    Somehow, intuitively, i thought, that the suggested addition,
    will increase flexibility, of the device.

    But now i am thinking that with speed regulation, provided,
    plus, pulling lever length adjustment, we have all the flexibility we need,
    and no need for this farther complication.
    Simple is, usually, best !
