Abstract: A retractable cabinet device has a base, two tracks and a cabinet. The tracks are mounted on the base and each track has a rail slot defined in the track and having a convex top surface. The cabinet is mounted movably on the tracks, selectively extends out or retracts back above the base and has two front wheel assemblies and two rear wheel assemblies. The front wheel assemblies contact the ground. The rear wheel assemblies are rotatably and slidably mounted respectively in the rail slots of the tracks. The retractable cabinet device is arranged in a compact and retracted configuration when idle to occupy less space and therefore facilitates use of indoors space where the retractable cabinet device is placed. Furthermore, the retractable cabinet device is stable and may be positioned in the using extracted or retracted configuration.

Abstract: A cabinet assembly has at least one cabinet. Each cabinet is a frame and has multiple erect bars, a front board, a rear board, a bottom board, a left opening, a right opening, a wheel assembly and an inner chamber. The wheel assembly is mounted on a lower surface of the bottom board and has multiple wheels and a substrate. The wheels are mounted on the lower surface of the bottom board. The substrate is mounted below the bottom board and contacts to the wheels, allows the wheels to slide on the substrate and holds the cabinet. The inner chamber is formed between the front board, the rear board and the bottom board and communicates with the left opening and the right opening. Therefore, users put the objects from both the left opening and the right opening, so the cabinet assembly is very convenient for the users.
