Introduction: Fixperts - a New Alternative Wheelchair That Provides a Solution for Mobility in the Home Environment
As part of the Fixperts exercise, we designed and created new alternative wheelchair that provides a solution for mobility in the home environment.
The chair was designed and built for a person amputated from the knee line down, a very active guy who does not need the standard wheelchair that conveys an unnecessary sense of disability.
The chair is designed with an "open source" approach so that anyone in the world with access to the right tools can produce it.
Designers and creators of the chair:
Ben Gavish & Aviv Haas
Supplies
IKEA STOOL KYRRE
scooter wheels
Abec 9 bearings
All the parts of the pipe should be cut first from a
28 mm thick pipe / 22mm thick / 13mm with a length of 2 meters
Step 1:
Here is the chair's manufacturing portfolio.
Each step of the process appears in this file.
Step 2:
Step 3:
Bend the Iron pipe L 620mm D 22mm to 90 degrees from the bend point
350mm from the bottom
Can also be connected
directly at 90 degrees
Step 4:
Cut two 22 mm long pieces from the 22 mm thick pipe and WELD to the area shown
Step 5:
Make sure the shaft is concentrically connected
Step 6:
Cut two pieces of pipe 170 mm long from the 22 mm thick pipe and WELD to the central axis which is 470 mm long
Make sure the pipes are connected at a distance of 80 mm from the end of the central axis
Step 7:
Take the 45 mm long pipe and connect it vertically to the area shown.
In order to create the front fork,
you need to cut a 4 mm thick segment in a laser cutting machine in the following layout
and bend it to 90 in the marked areas
Step 8:
In order to connect the axis correctly, you need to take two stabilizers that can be found in X-size skateboards
In order to correctly place the bearings,
you need to take a 28 mm thick pipe and
a spacer 31 mm long and
9 mm thick in order to prevent the radiators from falling inside the pipe
Step 9:
Take a metal segment 3 mm thick and 40 mm wide. Cut to a length of 60 mm and bend to 90 degrees
Step 10:
In order to make the brake, you need to take the 13 mm pipe and
cut it according to the list of materials and weld it according to the description. It is important to *pay attention
to connect the 90 degree joints inside
the holes for the brakes that we made beforehand.
The bending rod should be connected after the joints
of the brakes are welded.
The bending of the handle should be done at 75 degrees or by
direct welding if bending not available
Step 11:
After you have cut the legs, take the metal segment 3 mm thick, 6 mm wide, 230 mm long,
drill 4 holes in it from each corner and bend it to 90 degrees.
Then, screw the segment to the bottom of the stool
