摘要

A system of folding mechanical components comprises a bearing ball, a stationary body defining at least one concave recess sized to receive at least a portion of the bearing ball, a rotatable body rotatably coupled to the stationary body and one or more button members. The rotatable body defines two channels therein, and one or more button members are sized to be disposed in the channels. Each button member defines a recess with a rounded concave portion sized to receive at least a portion of the bearing ball. In a locked position the bearing ball contacts the sloped recess of the stationary body. In an unlocked position the bearing ball contacts the rounded concave portions of the button members and has relatively more contact with the concave recess of the stationary body.
