Abstract: A shelf structure has a frame member, a layer member and at least one reinforcement board. An outer surface of the frame member has a plurality of parallel ribs and an inner surface of frame member has a contacting face between each two ribs. An upper end and a lower end of the frame member respectively has an upper portion and a lower portion parallel with each other. A lower surface of the upper portion has at least one protruding rib. The lower portion is smaller than the upper portion. The layer member is assembled in the frame member and overlaps the upper portion of the frame member. The reinforcement board has a length equal and parallel to two opposite sides of the frame member and secured to the other two opposite side of the frame member.

Abstract: A foldable shelf may comprise a main body having two vertical connecting rods respectively located at middle portions of two sides of the main body at corresponding positions, and four vertical legs are respectively assembled at four corners of the main body to support at least two pairs of rotatable shelf boards therebetween. Each of the connecting rods has a connecting member coupled on an inner edge thereof, and each of the connecting members is pivotally connected to a V-shaped connecting rib. The foldable shelf further comprises two operating ribs at the top portion thereof. A user can pull the operating ribs upwardly to drive the pairs of the shelf boards to be folded together and drive the legs at two lateral sides of the main body to move toward each other, thus completing the folding process easily and quickly.

Abstract: A shelving structure may include at least four vertical posts, at least four annular spacers, and at least a shelf board, and the posts are configured to be mounted on the shelf board through the annular spacers. The shelf board has a frame and a panel, and a convex portion is formed at an inner edge of the frame. At least eight horizontal supporting boards are formed at four upper edges and four lower edges of the frame respectively. Each two adjacent supporting boards are not connected to each other, and each of four corners of the frame is bent to form a concave groove. Moreover, four arc boards are respectively assembled with the four concave grooves, and each of the arc boards has two wings configured to be welded with the convex portion of the frame to improve the structural strength of the shelving structure.

Abstract: A shelving structure may include a plurality of sleeves and wire shelves. Each of the sleeves has an upper opening and a lower opening for connecting purpose, and a plurality of connecting holes are formed on the sleeve. Each of the wire shelves comprises a bearing surface formed by welding of cross steel bars, and each of edges of the wire shelf is formed by welding of the steel bar. Each of inserting spaces is formed at the corner of two adjacent edges of the wire shelf. Each of the sleeves is connected at the corner of the wire shelf, and each of the steel bars on the edge of the wire shelf is connected to the connecting holes of two adjacent sleeves at two ends. The sleeve is stamped by a module of a stamping machine so as to deform and connect the connecting hole and the steel bar together.
