Instructions on Completing Mock-Up of Track Slide Design for Lift/Lower of Center-Mounted Footrests on Power Wheel Chairs

Step 3 Creating a Hinged Track Slide

The track inset will need to be cut again. This time, the cut is made, so that when the track inset travels up the track baseand reaches the catch-lock (shown in Fig 4, 3rd Image of Step 2), it does not extend past the seat well (bottom underside of seat). Place the track slide, vertically, near the base of the footrest, and extend the track inset up, from the track base until it locks into the base's locking mechanism (mentioned in step 2). The track inset may travel above the plane of the seat well, and would interfere with transfer. Measure the point at which the track inset travels above the plane of the seat well, you will want to cut at this point (See 1st Image).

The track inset can be cut via tthe hacksaw.

Now you need to connect the two cut pieces with a hinge. Find a small hinge, as shown in Fig 5, 2nd Image.

Locate holes on both pieces of the track inset to drill, of appropriate size. Make sure the track inset pieces line up, drill holes, and use rivets to secure the hinge. You will need to file down the rivets.

Final result is shown in Fig 5, 2nd Image. I used .125 in sized rivets, and a .133 in sized drill bit for drilling into the track inset.

Before I continue with the next stops of modifying your track slide w/ hinged track inset, I want to show the final result, and steps 4-6 will detail how to do one portion, outlined below in Fig 6, 3rd Image.
