Patent CN217851794U
Updated November 2, 2026Six-Fold Portable Chess Table with Integrated Storage
Standard outdoor tables are bulky and offer no storage for pieces or seats. This design solves both problems with a six-fold mechanism. The tabletop panels hinge together and slide over fixed layers, reducing the footprint significantly. Beneath the surface, sliding trays extend to hold game pieces, while a deep drawer stores larger items. When fully collapsed, the central frame forms two voids specifically sized to hide two folding chairs, turning the entire set into a single transportable block.

🔄
Six-fold mechanism
The table collapses through six distinct folding steps into a compact, stackable unit.
🪑
Hidden chair storage
The central frame creates two spaces that perfectly fit two folding chairs when stowed.
🎲
Integrated game storage
Sliding layer boards and a large drawer keep pieces organized and protected during transport.
📐
Compact footprint
The folded volume reduces to one-quarter of the original desktop area for easy carrying.

The problem
Traditional portable tables for board games often lack storage, forcing players to carry separate boxes for pieces and bags for seats. They are also difficult to pack away because they do not nest efficiently. When used outdoors or in clubs, finding space to store chairs between sessions is a common inconvenience. A solution is needed that combines the table, piece storage, and seating into a single, easily transported package without increasing the weight or bulk beyond reasonable limits.
The solution
This patent describes a table constructed from symmetric plate blocks and hinged components. The core innovation lies in how the parts interact to reduce volume. The first edition block contains the main tabletop pieces, which are hinged to allow them to fold over each other. Underneath these pieces are layer board covers that house movable layer boards; these boards slide out to create additional surface area or storage slots when the table is open, and retract to minimize size when closed.
The second edition block features a central tabletop piece supported by a lifting frame shaped like the character “three”. This specific shape creates two rectangular voids on either side of the central column. These voids are dimensioned to accept folding chairs, allowing the seats to be tucked inside the table’s base structure when the unit is collapsed. An elastic clamping plate holds the folded panels securely in place, preventing accidental unfolding during transport.

Who it is for
- Community centers and clubs looking for durable, self-contained gaming stations that can be moved between rooms or stored in closets.
- Outdoor event organizers who need portable furniture for markets or parks where space and setup time are critical constraints.
- Educational institutions seeking teaching aids for logic games or chess classes that include all necessary components in one kit.
- Retail brands specializing in niche hobby furniture who want a differentiated product with built-in storage solutions.
How it works
The main parts
| No. | Part | What it does |
|---|---|---|
| 1, 2 | Tabletop pieces | Hinged panels that form the playing surface; fold inward. |
| 3 | Layer board cover | Housing for sliding trays; length is 1.35x the tabletop piece. |
| 4, 5 | Central & Fourth pieces | Additional hinged panels completing the table geometry. |
| 6 | Movable layer board | Slides within the cover to adjust surface or storage depth. |
| 7 | Elastic clamping plate | Secures the folded assembly using hinge connections. |
| 8 | Lifting frame | Central support shaped like “three”, creating chair voids. |
| 9 | Core layer board | Structural plate congruent with the central tabletop. |
| 10 | Welt | Connecting component with bolt-shape fronts and wall-shape sides. |
| 11 | Table leg mechanism | Outer and inner plates with belt-shaped guy ropes for stability. |
| 12, 13 | Drawer sleeve & Drawer | Large-capacity storage unit sliding within the sleeve. |
| 14 | Hoop board | Retains the drawer within its sleeve. |
Opening and closing
- Unfold the legs: Pull the outer and inner plates of the leg mechanism apart; the belt-shaped guy ropes guide them into a stable, ground-contact position.
- Open the frame: The central lifting frame expands, revealing the two spaces intended for the folding chairs.
- Deploy the tabletop: Unhinge the first and second edition blocks. The hinged joints allow the panels to rotate outward until they form a flat, continuous surface.
- Extend storage: Slide the movable layer boards out from their covers if extra depth is needed, or access the large-size drawer via its front handle.
- Collapse: Reverse the process. Fold the tabletop panels over the central core, slide the layer boards back in, and fold the legs up. The elastic clamping plate snaps shut to lock the unit.

Applications
Community clubrooms
In shared spaces, furniture must be moved quickly. This table allows volunteers to collapse the unit and store the chairs inside it, clearing the room floor in seconds after a tournament ends.
Outdoor educational workshops
Teachers can transport a complete chess or strategy game station in one vehicle. The integrated drawer keeps small pieces from scattering in the wind, while the sturdy leg mechanism provides stability on uneven pavement.
Home entertainment corners
For households with limited space, the table serves as a dedicated game zone that disappears when not in use. The aesthetic of the folded block is compact enough to fit behind doors or in narrow hallways.
Retail display fixtures
Brands selling board games can use this table as a demo station. Customers can try out complex games on a stable surface, and staff can quickly reset the display by folding the unit and storing the props in the hidden drawer.
Where it is less suitable
- High-frequency commercial venues: If the table is opened and closed hundreds of times daily, the hinges may require more frequent maintenance than static furniture.
- Heavy-duty industrial settings: The materials described are optimized for light-to-medium loads typical of board games, not for holding heavy machinery or tools.
- Fixed installation sites: The complexity of the folding mechanism adds cost and weight compared to a simple, permanently installed wooden table.
Frequently asked questions
How many steps does it take to fold?
The patent describes a “six-time folding” process. This involves collapsing the tabletop panels, retracting the sliding layer boards, securing the elastic clamps, folding the central frame, and finally stowing the legs. Each step prepares the next, resulting in a compact block.
Does it really hold chairs inside?
Yes. The central support frame is shaped like the Chinese character “three,” which intentionally creates two empty rectangular spaces. These spaces are sized to fit standard folding chairs, allowing you to store two seats directly inside the table’s base when it is collapsed.
Is the leg mechanism stable?
The legs use a system of outer and inner plates connected by belt-shaped guy ropes. When pulled manually, the plates unfold flat against the ground, and the ropes keep them taut. Stability depends on the tension of these ropes and the precision of the hinge connections.
Can I change the materials?
The patent focuses on the structural geometry, not the material. You can produce the panels in wood, metal, or composite laminates. The key is maintaining the relative sizes of the plates so they still interlock correctly during the folding sequence.
What is the storage capacity?
It includes a large-size drawer sliding in a sleeve, plus movable layer boards that can extend to hold smaller items. The patent does not specify a volume in liters, but the drawer is designed to accommodate significant game equipment or accessories.
Is it suitable for outdoor use?
The design is portable and compact, making it good for events. However, weather resistance depends on the materials chosen for production. Aluminum or treated wood would be better than untreated MDF for long-term outdoor exposure.
Can this design be made and sold in the US?
The patent is filed only in China and is active there. There is no corresponding US patent for this specific design. Therefore, this particular patent does not restrict sales in the US. However, always check for other existing US patents in the folding furniture sector before launching.
