The
Sealander
|

|
This
plastic molded wheelchair is tough, water-friendly and non-rusting.
Made from ultra-violet-resistant plastic with nylon wheel bushes,
stainless steel axles and aluminium tube footrest, the Sealander
can be immersed in salt water without damage. This wheelchair
suits bathing and use on beaches and can be fitted with a commode/toilet.
The
Sealander is available in three models with seat width of 15".
The
"BEACH' model is fitted with 10" and 14" diameter
plastic wheelbarrow wheels and wide 4" tyres for traction
on sandy and bush terrain. The front wheels are fixed.
The
standard Sealander has 24" diameter plastic wheels and solid
rubber tyres, eliminating punctures. Castor wheels have 8"
diameter solid tyres. Axles are 0.5" stainless steel rod.
Note:
Regular cleaning to remove sand will stop damage to axles
|
MEND
can supply the Sealander molds & license and setup technology for
local manufacture in any country.
Tricycles:
|


|
In
Sri Lanka and Souh India (1999) and Nepal (2000) MEND developed
protoypes of chidren's size tricycles using locally available
steel tubing, 20" BMX bicycle wheels and a plastic seat.
Costing $50US in materials this tricycle can be pedalled and steered
using both hands. Tricycles can be made in a small workshop in
a few hours.
Tricycle users can travel long distances over flat country --often
50 kms a day!

Walkers
 |
A
walker can help a disabled person become mobile, is good for exercise
and encourages independence. Our standard walker can be made locally
and can be fitted with a fold-down seat and back harness. With
her new walker, this 12 year old Fijian girl has now regained
some independence..
Costing
as little as $10-$20US walkers can be made of wood, steel and
aluminium tube, fibreglass and plastic.

'Islander'
wheelchair
 |
This
3-wheel design can also be immersed in water and used outdoors on
beaches and for bathing. It can be scaled up to suit any user's
weight. Wheelbarrow or wheelchair wheels can be fitted. This disabled
man (see right) has adapted a towbar to his Islander wheelchair
so that he can be towed by a tractor along the beach into knee-deep
water, to enable him to swim.

Trolley
/ Gurney
 |
This
aluminium trolley design combines a commode/toilet for a disabled
person who has difficulty sitting. A bucket is placed underneath
and it all can be washed down, there being no parts to rust. The
12" diameter wheels use inexpensive nylon bushes (50 cents
each) that can be replaced without any technical skill. The seat
is made from trampoline material and laced onto the frame. This
trolley can be used on on beaches and for bathing too. The sloping
base suits comfortable oudoor sunning and stretching out of legs.
Weight
is about 8 kgs.

Low-cost
Wheelchairs
|
Using
a solidly welded frame and a single front castor wheel this design
is cheap to build and sturdier than folding models for rugged
areas.
Note: A wheelchair with 3 wheels is often stabler
than 4 wheels on rough ground as all wheels touch the ground.
Seating
can be made of leather, nylon webbing, car tyre inner tube, ply
& foam or plastic.
Cost
to build in India is about $35-$40US.
Children's size uses 20" diameter BMX bicycle wheels, while
adult's size uses 24", 26" or 28" diameter back
wheels.
Note
: Ordinary bicycle wheel axles are 3/8" diameter and if used,
an outer support arm is necessary. If the hub is replaced by a
0.5"diameter axle (as on rickshaw wheels) it can then support
user's weight.

Pedal Car
 |
This
vehicle can be propelled by hand or foot, or small gasoline or
(solar) electric motor. It can enable a disabled person to travel
with another disabled person, their family or caregiver. Luggage
and goods can be transported as well as passengers. This design
protects the cyclists from both sun and rain, and from other vehicles.
It is constructed of steel or aluminium tubing and standard bicycle
parts and 20" diameter rickshaw wheels.
|
Cost
to make is about US$150 in steel or US$250 in aluminium.
Note: MEND is developing a plastic pedal car that will
be suitable for urban use and also pedalled by hand of foot.
Fibreglass
Wheelchairs
 |
Developed
to be made and used in the Pacific Islands where fibreglass is
much used for building boats these wheelchairs are tough, waterfriendly
and low -cost. Even the wheel rims can be made of fibreglass,
minimising the importation of additional materials.
Costing $250US to make they are produced in two sizes in the Solomon
Islands using 20" solid-tyred back wheels for children and
26" mountain bike wheels for adults.

 |
Bed / Wheelchair
   
This
design was developed for the poor for whom their wheelchair can be both
a means for mobility during the day and a bed at night. In India many
disabled people must sleep outside and it is cleaner for them to sleep
on their wheelchair. The back folds down for sleeping or folds forward
for packing.
