Una-Crutch: Right Move, Right Place, Right Time

Project Summary Project Information

PRP available at this link, Project Readiness Package.

Project Summary: When a leg injury occurs, medical axillary crutches are normally issued to the patient and become a very crucial piece to the injured person’s mobility. Crutches were initially created as a walking stick by A.R. Lofstrand, Jr in 1945. They are used to help the person move around by placing one crutch under each armpit and are subjected to the force from the person’s weight. Standard axillary crutches are mainly useful for open areas but for smaller and condensed spaces, it is easier to use one crutch. Therefore, it is important that a person can alternate between using one or two crutches. By creating the Una-Crutch, a person’s mobility can always be at its full potential with the capability of combining two individual crutches into one and combining them back together. With a simple locking mechanism, the Una-Crutch can easily be modified all while ensuring the person’s comfort and placed on all axilla crutches. The device is always in a safe condition, no matter the modification of the crutch that it currently is in. The Una-Crutch gives standard crutches more uses as it is comfortable, easy to modify, and safe.

Final Products: Two designs were modeled, built, and tested for this project.

1. The Una-Crutch Latch is an add-on to the standard crutches and utilizes the original handles. A latch flips around and couples the individual crutches.

2. The Una-Crutch Handle is a redesigned handle which replaces the standard crutch handles. A sliding button connective mechanism couples the individual crutches.

Both designs are shown in the figures below.
