Guidelines-
Minimum Wheelchair Requirements
The Dragonfly
TM
is designed to accommodate most wheelchairs. There are specific
requirements that your chair must meet in order to safely attach and use the Dragonfly
TM
. Please
refer to the following table and associated pictures on the next page to determine if your
wheelchair meets the necessary specifications.
Chair
Configuration
Wheelchair must have pushrim wheels in the rear, castors in
front.
Wheelchair
Frame
The geometry of the tubes at the front of your wheelchair must be
similar to one of the 3 wheelchair frames shown in Figure 1
(page 10), specifically the regions where the clamps attach. If
your wheelchair is not similar, please contact Customer Service
at support@riomobility.com.
Wheelchair
Frame Tube
Diameter
For our standard product your wheelchair frame tube size must
be 1 inch (25.4 mm) in diameter. To measure your tube
diameter, cut out the ruler on the bottom of the next page and
wrap it around your frame tubes at the 4 clamp locations for your
wheelchair frame shown in Figure 1 (page 10). Note where the
lines line up.
The tube should be straight (not curved) for the width of the
ruler.
For frame tube diameters of 1 ⅛inches (28.6 mm), 1.2 inches
(30.5 mm), and 1 ¼ inches (31.8 mm), order a set of 4 clamps for
the appropriate tube size.
Rear wheel
axle position
When seated in the wheelchair, your center of gravity must be far
enough forward of the rear axle so as to make “wheelies” or
tipping backward difficult – THIS IS VERY IM PORTANT. If
the chair is currently set up so that “wheelies” are very easy, it
will be very unstable and very unsafe when the handcycle is
attached, leading to possible serious injury to the head, neck, or
other parts of the body.
Anti-tips are also required.
Chair width Wheelchair seat width must be between 12” (305 mm) and 20”
(510 mm) wide.
Wheel Locks Wheelchair must have wheel locks installed.
Weight Combined wheelchair and user weight of less than 280 lb. (130
kg.); user weight no more than 250 lb. (115 kg.)
