Abstract: The shelf device mainly contains two rectangular top boards horizontally arranged side by side on top of a frame structure formed by at least three vertical and two horizontal frame members. Each vertical frame member has a number of horizontal beams each horizontal frame member has its two shorter edges hinged to the horizontal beams of two vertical frame members at the two sides of the horizontal frame member. The shelf device can be easily collapsed by lifting a handle on the top edge of the vertical frame member in the middle. When that happens, due to the way the vertical and horizontal frame members are hinged together, the top board and frame structure at the two sides of the shelf device are automatically closed towards each other. At last, the shelf device becomes a flat object for easy storage and carry.
