Abstract
A refrigerator appliance and variable shelf assembly are generally provided herein. The variable shelf assembly may be mounted within the refrigerator appliance and include a stationary support screw extending along a movement axis, a mated screw, a shelving bracket, and a bi-directional ratchet gear. The mated screw may include an interior surface and an exterior surface. The interior surface may be rototranslatably mounted on the stationary support screw to rotate about the movement axis during translation therealong. The mated screw may be coaxial with the stationary support screw. The shelving bracket may be coupled to the mated screw. The shelving bracket may be rotationally fixed to translate along the movement axis. The bi-directional ratchet gear may be operably coupled to the mated screw to motivate rototranslation of the mated screw.
