Breadspread Aid is designed to automatically remove a bedspread for those with limited upper extremity strength and mobility associated with spinal muscular atrophy, arthritis, or stroke.   

Technical Specifications: 

This breadspread aid solution is controlled with 2 strings. One string is for removing the sheet and the other string that is located in the base to to place the sheet back. The strings are powered by a motor (the motor is not discussed in this instructable).

Step 1: Materials
M5 countersunk bolts of 25 millimeters long
M5 nuts
Some screw of 25 millimeters long
1 meter of non-stretch fabric (jeans is a good)
1 square meter of wood approximately 20 millimeters thick (multiplex, natural)
1 meter long wood plank of minimum 40 millimeters wide and 15mm thick
2 wooden planks of 1 meter long, 25 millimeters wide and around 8mm thick
5 meter of smooth ribbon
6 buttons

Step 2: The Tools
Cordless drill (column drill is also advised)
Wood milling machine
Allen keys
Sewing machine

Step 3: The Milling
Before cutting the wood planks you must first mill the wood. For the wide plank, cut a groove in the middle of the wood approximately 10 millimeters wide and 1.5 5 millimeters deep in his length. This groove is for the ribbon. For one of the thin planks, cut a groove in the middle of 8 millimeters (the wideness of the nuts) and 2 millimeters deep in the length. Now the chamfer milling on each side of the plank, we used an angle of 60 degrees.

Step 4: Cutting and Drilling
The cutting: take the wide plank that has been cut into smaller pieces the same width as the thinner plank; the 2 thinner planks should be cut as the same width as the wide plank.
The drilling: drill holes of 8 millimeters through the pieces of wood. This step you can be completed before all of the cutting when you measure everything, or after the cutting. You can secure the 3 pieces of wood together and drill through all 3 pieces of wood in one drill movement. The pieces where there are not milled need a countersink in them.

Step 5: The Fabric
Cut the approximate length of the fabric with a wideness of 40 millimeters extra as the wideness as your widest plank. now lay your thickest pieces on the length of the fabric, leaving 10 millimeters of spacing on each side of the fabric. Mark the spots where the holes are for cutting them out. The cutting will work with a perforator. Another technique is stabbing the holes through with a thin pointy object.

Step 6: Sewing
After every segment is made, you can check the function of the construction (see next step). If everything checks out you can sew the edges and place some buttons on the side, and the counter buttons on the sheet.

Step 7: Assembly
First, assemble the bottom part; this consists of the small piece with the countersink and the large piece with the ribbon in place. For the first piece tie the ribbon or secure it with a knot. Then place the fabric over the piece of wood with the chamfers. The last thing is to use the Allen key to keep it all together. Complete this step for all the pieces.

Step 8: The Holder
This piece is to hold the previous assembly secure to the bed. These dimensions were all very situational. It can vary to your needs. There need to be a flat surface on the frame of the bed where you can drill 1 hole in for this to work.

Step 9: The Cutting and Drilling
The general idea is 3 main parts and 2 other smaller parts. Use the fretsaw to saw out these parts of the wood. First, start with the middle portion of the wood. The long neck is for bridging the thick mattress. The segment where the rod is already in is where it contacts the bed frame. Be sure to insert a hole there. Secondly, the two other main parts need to be symmetrical. The left segments of the part hook on the bottom side of the bed frame. You can shape them that way so there is a snug fit. The last parts are the smaller ones. These need to have a good length to be over the mattress. Another important thing here is the incision for the fabric to fit.

Step 10: Assembly the Holder
Assemble the parts using the screws with the right spacing. You can pre-drill holes and countersinks for a smoother fit. When the holder is made you can sand the last piece of the other assembly down so it is a good fit in the holder (see picture).
