Fixperts - Liffting Apparatus From the Floor

Hello dear maker! This project was developed as part of the FIXPERTS course in the Bachelor’s Industrial Design program at the Holon Institute of Technology (HIT) in Israel, with the goal of creating a product that increases independence for people with disabilities in their daily routines. Our work focused on Michal, a remarkable woman who is paralyzed from the chest down and hopes to join her two young children as they play on the living room floor—an activity that requires her to move from her wheelchair to the floor and back again. Currently, she accomplishes this by effectively “falling” out of the chair and then using the sofa to pull herself up, a process that is both difficult and physically taxing. In response, we (students Moria Ido and Aviv Haas) designed a railing system intended to simplify and support Michal’s transition from the floor to her wheelchair.

Please look at the PDF files, there are instructions and specific markings where to weld and drill.

Please note that our product is still in development as part of an academic project, so if any dimensions appear inconsistent during construction, feel free to adjust them to suit your needs. We hope you enjoy building this product and that it can be of benefit to you or someone you care about.

Designers and creators of the railing system:

To create this product you will need 22mm and 25mm metal tubes.

Access to a 3D printer where you can print in flexible TPU material.

A wooden board served as a seat.

A pipe bender with a 60mm bending backgauge.

You will need to cut the pipes according to the cutting list.

Take the pipe of length 1820mm and bend it using a 60 mm Beck pipe bender with a diameter of 22 mm and bend it to 90 degrees in the marked areas.

Do the same thing as in the first step.

Take the pipe of length 1890mm

Then weld the two bent pipes in the marked areas

After welding, cut the pipe in the marked area, 24 cm from the marked end.

After welding, cut the pipe in the marked area, 24 cm from the marked edge.

Then drill a 10 mm diameter hole 15 mm from the marked edge.After you have drilled the 10mm hole, carefully insert the locking pin.

Take a 25 mm diameter pipe and cut a 65 mm long piece from it. Drill a 10 mm diameter hole 23 mm from the marked end.Then weld the 25 mm diameter pipe so that the 22 mm pipe overlaps the inside by a depth of 3 cm.

Carefully insert the locking pin into the 22mm tube until it enters the designated hole.

Check that the locking pin passes through both tubes and that the lock is good.

Bend the pipes so that they complete a half shape as shown in the diagram. After bending, cut one end to a depth of 22 mm. Then weld the cut end to the pipe as shown in the diagram. The distance between the pipes is 17 cm.

Cut a piece of wood measuring 25 cm x 25 cm and 20 mm thick. Pre-drill holes in the wood for the final connection to the frame. Use self-tapping screws and carefully screw the seat to the frame.

Pre-drill holes with a diameter of 5.5 mm in the marked areas and connect the printed parts according to the drawing.

Print the 3D files in the orientation shown in the pictures.

Attention!

Extend the Z-axis wheel lock model to 25 mm.
