Simple Installation Type Slope —CS-11

For (With Whom)

People who have difficulty moving over a raised threshold with a walker.

Why

During a home-visit rehabilitation session, when the user returned from the hallway to their room, the front wheels of the walker hit the threshold, and I saw the user struggling to lift the walker each time. This was made to make going in and out a little easier.

How

A trial slope was made, but its incline was so steep that it could not get over the threshold (yellow, upper left image). So a slope with a gentler incline had to be made again. Since a gentler incline was expected to require more front-to-back width, a piece sized to the tire diameter (green) was printed. However, extending the slope still left the incline too steep, and the slope itself slid on the floor, so TPR (blue) was printed again and combined with it (left image).

Outcome

With the newly made slope, the user can now get over the threshold just by pushing the walker with their own strength.
