This project is a simple and inexpensive transfer system that allows a wheelchair user (or any individual with mobility issues) to easily be transferred from their wheelchair to a bath for bathing purposes with the assistance from another individual (or by themselves, depending on the situation).
Before this project was given to us the process of Rosa giving her daughter Vanessa a bath was quite a labor intense process by where she needed to physically lift her into and out of the bath. This did not only put unnecessary strain on Rosa’s back but it was also not a completely safe for Vanessa as well. After getting plenty of input from Rosa which included a picture of a preexisting idea that she liked, we began to come up with ideas that we believe best suited her needs.
The system is made of 3 separate pieces:
3) Rolling Platform for the chair
Plywood 1/2" thickness
2 to 3 hinges
Aluminum beach chair
Swievl for a boat seat (can be found at a marine store)
4 Caster Wheels (1/2")
3 Gate latch
Stainless Steel U-Bolt, 1/4"-20 X 1" Thread Length, for 1" OD
C-bar (enough length to run the full length of the platform on both sides)
Enough bolts, washers, and nuts to attach all the nessecary parts
Quoc Vhin for working on this project for 2 quarters
And other Engineering students for their input
Step 1: Cutting the Base to Size
The overall length of the base is equal to the overall width of the tub plus the height of the tub.
The width of the base we used 15".
For the hinging aspect of the base, measure from one end of the base (the height of the tub) then make a cut across.
Use either 2 or 3 hinges to attach the two pieces of the base.
Step 2: Drilling the Holes for Attachment of C-bar
Step 3: Cutting the Folding Legs
We used 2 table leg hinges to allow the legs to fold up and down. We used simple square legs. Since the legs were the same lenght as the floding extyension, we had to coss the legs because they wouldn't fit if we folded it into the platform.
Step 4: Modify a Pre-existing Folding Chair
The only thing that needs to be done to the chair is for the legs to be cut as short as possible, so that it will easily fit onto the platform.
(We used a simple hack saw to make the cuts)
Step 5: Making Brackets for Latch
Step 6: Cutting the Bottom Base of Rolling Platform
The bottom base is used to attach the 4 caster wheels and the swivel.
The overall dimension is 14-1/4"W and 16-5/8"H
Step 7: The Top Base of the Rolling Platform
The Overall dimension of the top base is 16.25 inch X 15.00 inch
Step 8: Coating Anything That Is Not Water-proof
Step 9: The C-bar Saftey System
Step 10: Finishing
