The shelf is designed to be movable rather than fixed, allowing it to slide forward and backward along guide rails. This dynamic capability enables users to easily access food items by pulling the shelf forward, while the guide rails and stopping members provide structural guidance and limits without requiring complex mechanisms.

The shelf system is divided into independent movable shelves that can be operated separately. Each shelf can be moved forward or backward independently along the guide rails, allowing selective access to specific food items without moving the entire shelf structure, thereby simplifying the access operation.

Instead of rotation, the shelf employs linear sliding motion along guide rails. This dynamic linear movement allows the entire shelf to be pulled forward to access back-stored items, eliminating the need for rotational space while maintaining full accessibility to all food items on the shelf.

The invention transitions from rotational movement (requiring radial space) to linear sliding movement along the depth dimension. By moving the shelf forward along the guide rails in the depth direction, accessibility is achieved without consuming additional lateral or vertical space that would be required for rotation.

Guide rails serve as intermediary elements between the movable shelf and the fixed storage chamber structure. These guide rails provide a stable track along which the shelf slides, ensuring controlled movement while preventing twisting or lateral instability. The guide rails act as mediators that enable movement while maintaining structural stability.

The twisting prevention function is extracted as a separate mechanism using stopping members that engage with the shelf. These stopping members are positioned to limit the forward movement of the shelf and prevent over-extension, thereby stabilizing the shelf structure during and after movement without interfering with normal accessibility operations.

The guiding mechanism uses simple linear guide rails that allow smooth sliding movement. These guide rails provide stable guidance through their geometric shape and positioning, enabling the shelf to move forward and backward without twisting. The simplicity of the linear guide structure minimizes complexity while ensuring stability during movement.

The stopping members change the movement parameter of the shelf by limiting the maximum forward displacement. This parameter control (movement distance limitation) provides stability by preventing over-extension and ensuring the shelf returns to its proper position, while the simple stopper design adds minimal complexity to the overall system.
