Lately I've found it nice to when sitting in a chair have a
fan on the floor in front of my feet,
blowing at my shins and knees. My knees have been a bit
sore lately and the cool air helps.
Plus, if
the weather is hot, that's a convenient place for the fan
to blow air across most of my body.
Anyway, sometimes I need to adjust the aim of the fan,
to blow at one knee or the other, or
both
evenly, or down at my shins, or up at the underside of
the table for reduced knee cooling. It's
easy
enough to do with my feet, because the fan is the vortex
air circulator type on a tilting mount
[link] with feet that can slide on the floor, but it can be
impreciseI have to make an
adjustment,
feel where it's blowing, and adjust again if necessary. If I
had a more finely controllable way
of
adjusting the fan's aim, that would be convenient.
Therefore, my envisioned fan would be on an altitude
azimuth mount, controlled by either
servo
motors with a remote control or Bowden cables (like bike
brake/derailleur cables) with
handles.
The Bowden cable option would be cheaper, but limited
in remoteness. The servo motor
option
would be more expensive, but you could mount the fan
farther away (such as on the ceiling,
even)
and still control it. It could even be programmable to
move in various patterns on its own,
whereas
existing fans with the oscillating feature are only capable
of moving in one axis and at a fixed
frequency.
This could also be useful on buses. You know how buses
have those little fans at the front that
the driver can aim by hand? Well, this could make it
easier to do that without getting up from
the driver's seat. In that case, because the spatial
relationship between the fan and the
controls is fixed, a rigid linkage of some kind could be
used.

A postvious idea of mine. These could be substitutes for each other to some extent, but I think this one is more suited for personal cooling, while the other is more suited for set-and-forget ventilation. [notexactly, Aug 26 2019]

I can see no reason why this does not already exist. [+] |
