Pogo-roo
Pogo stick with kangaroo type assisting tail | |
Pogo-roo is a refinement of the
conventional pogo stick and is based on
the appearance, action and resulting
motion of a kangaroo's tail.
The tail is attached across the pogo-stick
mid shaft, and protrudes backwards
between the legs of the user. It is
balanced on damped
springs, and
counterweighted, so that as
the pogo-stick jumper bounces and
leans forward, the tail adds
considerably to their speed and motion.
It
achieves this by following the same
principal of the animal it imitates.
Tails are adjustable to match the
characterstics
of
their individual users, in amplitude,
weight and
resistance.
Pogo-roo !! Go jump like a Kangaroo.

It's this a kids' toy or a sex aid? |
|
| |
that depends on the range of amplitude
you set on the tail's movement. |
|
| |
And on every landing whatever inertia is not absorbed by your knees is absorbed by whatever bits hit the tail you are straddling. Ouch. |
|
| |
I like it. This will allow you to lean forward and get the thing going. [Ah...but you said that!] |
|
| |
[GC] You never come into contact with
the tail, and much of the inertia of a
pogo-stick is tranferred into the energy
stored in the spring, to be released on
the next jump forward, assisted in this
case by the tail. Seems to work fine on a
kangaroo anyway, hence the idea. |
|

I don't see that the tail helps a kangaroo bounce. A tail on a pogo stick is going to add weight and complexity, besides bollocking up the balance and rotational inertia. |
|

[baconbrain] //I don't see that the tail
helps a kangaroo bounce// You cannot
be serious ! |
|
| |
Yeah, I am serious. I can see the tail as a stabilizer and a counterweight, which might help a bouncing kangaroo stay upright, but I don't see it as something to make a 'roo go higher. |
|
| |
Nor can I see where a tail is going to help a pogo stick. I haven't jumped on one for years, but I used to be good at it, and never thought a tail was needed (and I am just the kind of guy who would have figured it out if one was). |
|
| |
Now, thinking about it, I'd rather put a tail-like counterweight on springs on the FRONT side of the stick to balance out my own backside. |
|
| |
Back to 'roos. If the tail is actively pulled up and down at the right times, it possibly could take some load off the leg muscles, at the expense of the tail muscles. But, on a pogo stick a spring-loaded "tail" won't have the muscles needed to give a useful boost. |
|
| |
//but I don't see it as something to
make a 'roo go higher// then you need
to study its motion a little more
carefully, and you might change your
mind. I suggest the BBC which has
extensive slow-mo videos. It's just not
something I feel I have to defend. The
motion speaks for itself, and can be
mechanically imitated. |
|
| |
You can of course wear your tail where
you choose. I'm sure a new strain of
kangaroo will eventually evolve with its
tail facing the front, and when it does
you can say "see told ya !!" :-) |
|
| |
Or it can say, "I really am happy to see you." |
