Some weeks ago, I asked about a hand cart
that could move both forward and sideways.
After googling and asking all over for such a
and getting no joy, this is my solution.
He's going to have trouble getting a patent, now that he's published it's
design to the world. Now it's considered "public domain". He should have
filed for a patent and then waited for the filing to be accepted before
showing his design to anyone. Then it would be listed as "patent applied
for" and he would have protection.
As the other said, "nice idea, well executed"...
How heavy is the rod? Looks like the potential "weak link" under a
heavy load, maybe. But, a lower additional support or just beefing it
up would take quite a bit to cause a problem, I'm sure...
The rods are 1/2" stressproof. And, you're right there may be a problem
with heavy loads, however the wheels have a load rating of 175 pounds,
so that limits the cart to under 400 pounds.
I have been unable to find 6" pneumatic tires, so that seems to be the
limiting factor. It would be very easy to use a 3/4" or 1" shafting to
beef up the weight limits perhaps by using 10" pneumatic tires with
6" steel caster wheels.
Thanks for the comments
Actually, if you were really intent on making/needing a heavyweight job,
strikes me you could add a tension rod onto the outside diameter of the
shaft when rotated that could clear the supports. Lightweight but very
strong in tension. Same idea as used on pole booms, for example.
