Lock Mechanism Concept Sketches 

These concept sketches are different ideas of how to safely keep the students in the merry go round. Majority of these concept sketches are designed around the wheels because it is the main component of all wheel chairs. Besides the wheels, all wheelchairs also share arm rests and push handles. In the sketches, there are divots, walls, and locks that limits the wheels movement. Some sketches are focused towards using the arm rest in the lock system. After researching on different types of locks, one way lock seems to be best fitting for the wheel chair due to how simple it is. Then, it is paired along a divot that provides additional security for the wheelchair. To provide extra security for the wheel chairs, I created few concept sketches that had 2 or more locks involved. - Antuane Clark
