How does it work?
The device starts
with a crossbow made by TenPoint Crossbow
Technologies in
Suffield, Ohio. This manufacturer's
crossbow is easier to adapt because the
trigger and rail can be removed together,
without the stock. Also, the quality of
construction in this crossbow is second
to none.

The
crossbow is modified so the trigger can be
activated by a DC solenoid. The solenoid is
operated by a pressure sensor switch. These parts
fit inside a steel box which mounts beneath the
trigger.
All of this is then mounted on top of a video
camera tripod head which bolts to a frame that
mounts to a wheelchair. Current is provided by
the 24V batteries from the power wheelchair.
 |
With just the use
of a chin, the crossbow can aim left and
right, up and down. Sighting is done with
a red dot scope.. While aiming, a simple
inhale on a tube will fire the crossbow.
Cocking the bow is accomplished by using
the electric cocking device made by Horton
Manufacturing.
Even the multiple shots necessary for
target archery require little effort with
this power assist.
