Description

Technical Field

[0001] This invention relates to the field of chess game equipment technology, specifically to a foldable, liftable, and deployable dual-purpose magnetic chess set. Background Technology

[0002] Board games are widely popular intellectual sports, with chess and Chinese chess having a large following worldwide. In practice, the board layout, number of pieces, and movement rules of the two games differ significantly. Users who wish to experience both games typically need to purchase two separate sets, which not only increases their financial burden but also makes them inconvenient to carry and store.

[0003] To address these needs, early attempts in the industry focused on integrating two chess systems into a single set of chess pieces. For example, a few pieces were added to the existing chess set to accommodate Chinese chess, with the "King" replacing the "General" and "Chief," and the "Queen" replacing the "Advisor" and "Guard." While this reduced the total number of pieces, the names and functions of the pieces interchanged, resulting in inconsistent movement patterns and a lack of intuitiveness and a high risk of errors. Regarding changing the chessboard, early products often used a pull-out insert design, which was cumbersome and lacked precision, leading to a poor user experience. The chess box also relied heavily on mechanical latches for closure, resulting in a bulky structure and large overall size, hindering portability.

[0004] Regarding the stability of chess pieces storage, existing portable chess box products face another prominent issue. Some products use foam padding or individual compartments to secure the pieces, which is effective when the box is stationary. However, when the box is squeezed or shaken during transport, the pieces still shift and collide within the storage compartment, causing wear and tear on the pieces and the inner walls of the box, resulting in the pieces scattering when opened. Furthermore, foam padding and individual compartments limit the flexible use of the internal space and increase the complexity of the manufacturing process.

[0005] More importantly, the aforementioned existing technical solutions are all limited to the single "open chess" mode, where all pieces of both players are visible throughout the entire game. However, hidden chess (where players' pieces are hidden during the initial placement phase and gradually revealed after moves or captures) and confrontation chess (where players take turns placing pieces in a specific order before starting the game), as more engaging and strategically profound game modes, have always lacked reliable implementation methods on a physical chessboard. Traditional chessboards cannot provide stable information concealment for both sides during the placement phase, nor do they have a clear mechanism to control when the identities of pieces are revealed after a move. This has led to higher-level games like hidden chess and confrontation chess relying heavily on verbal agreements or temporary concealment, making it difficult to guarantee a good gaming experience.

[0006] Chinese patent document CN2865800Y discloses a magnetic Chinese and international dual-use chess box. It discloses a technical solution that achieves non-substitution of chess pieces by adding special chess pieces to the basic Chinese chess pieces, uses a double-sided magnetic thin plate chessboard to flip and switch the game rules, and magnetically fastens the chess box frame. It achieves the technical effects of sharing chess pieces without confusion, easy switching of game rules, and portability of the chess box. However, it still has problems such as the chessboard being a static planar structure without spatial deformation ability, only supporting open chess games and not enabling information visibility control gameplay such as hidden chess or confrontation games, and the lack of a dedicated return path for chess pieces.

[0007] Chinese patent document CN121314174A discloses a multifunctional combined magnetic chess box. It discloses a technical solution that uses a detachable and replaceable second chessboard to adapt to multiple chess games, a locking mechanism that uses a cone-shaped part to drive the pressure plate to automatically press the chess box, and a double fixation of the chessboard by magnetic attraction and locking of the socket and the insertion post. It achieves the technical effects of a single chess box being compatible with multiple chess games, preventing chess pieces from colliding and wearing out when carried and shaking, and avoiding accidental opening of the chess box. However, it still has the problems of requiring the replacement of an independent chessboard plate for chess game switching instead of in-situ deformation and transformation, limited integration, and only supporting open chess games, without being able to achieve the concealment and directional disclosure of chess piece information during the game. Summary of the Invention

[0008] The purpose of this invention is to provide:

[0009] A foldable, liftable, and deployable dual-use magnetic chess set for both Chinese and foreign players, and related technologies, to solve the technical problems of existing chess sets being unable to simultaneously support dual-chess system switching and hidden chess information visibility control on the same hardware set, and lacking integrated portability from unfolding to playing and folding for storage, or a combination thereof.

[0014] Furthermore, the interiors of the first and second chess boxes are hollow structures used to store the chess pieces.

[0015] Furthermore, the rotating structure is a damping shaft.

[0016] Furthermore, the rotating structure is a cylindrical rotating shaft, with a fixing block on one side of the rotating shaft. The fixing block has multiple protrusions, and the first chessboard fixing surface and the second chessboard fixing surface are respectively provided with matching protrusions on the fixing block.

[0017] Furthermore, the rotating structure is a rotating link, and the frame is provided with grooves that match the rotating link. The first end of the rotating link is fixedly connected to the midpoint of the side of the chessboard fixing surface, and the second end of the rotating link is slidably connected to the groove. Multiple support points are provided inside the groove.

[0018] Furthermore, a snap-on button is provided on the frame, a support structure is provided on one side of the inside of the chess box, a spring assembly is provided inside the support structure, and a protruding structure matching the snap-on button is provided on one side of the chessboard fixing surface.

[0019] Furthermore, a rigid fixing structure is provided on the side of the chessboard fixed surface near the inside of the chess box. The rigid fixing structure includes multiple square frames, and multiple interconnected hexagonal structures are provided inside the square frames. The rigid fixing structure is made of plastic.

[0020] Furthermore, the side of the chessboard fixing surface closest to the inside of the chess box is provided with stainless steel. The stainless steel is square in structure, and there are multiple stainless steel pieces arranged in sequence at preset intervals to cover the entire chessboard fixing surface.

[0021] Furthermore, the chess piece has a polygonal structure with a non-circular cross-section. Each side of the polygonal chess piece is equipped with a magnetic piece, and the magnetic properties of the magnetic pieces facing outwards are the same.

[0022] Furthermore, the first chess box and the second chess box are respectively provided with handles on their outer sides, and the first chess box and the second chess box are respectively provided with matching locking structures on their outer sides.

[0023] Secondly, the present invention provides a method for playing chess using a folding, lifting, magnetic chess box based on any one of the first aspects, comprising the following steps: S1: Determine the orientation of the chessboard according to the selected chess system, pull the chessboard out from the fixed surface of the chessboard, flip it to the corresponding chess system surface and then reset it so that the fixed surface of the chessboard presents the selected chess system pattern. S2: Select the corresponding piece from the pieces according to the selected game mode. If the open game mode is selected, all pieces are placed on the fixed surface of the board in the first placement state to complete the placement. If the hidden game mode is selected, both players place their own pieces on the fixed surface of the board in the second placement state, so that the information labels of the pieces of both players are not visible to each other. S3: In the Dark Chess mode, when one side makes a move or captures a piece, the piece is changed from the second placement state to the first placement state, making the piece's information identifier visible to both sides.

[0024] Furthermore, S2 also includes a confrontation chess placement mode: the first player places one piece, and then the two players take turns placing two pieces each until all pieces are placed; after the pieces are placed, the two players can choose to continue playing in the hidden chess mode, or change all pieces to the first placement state to switch to the open chess mode.

[0025] Embodiment 1 of this invention at least supports the protection scope of claims 1-10.

[0026] The present invention has at least the following beneficial effects: 1. The chessboard fixing surface of this invention is connected to the chess box frame via a rotating structure. It can be raised from the storage position to the operating angle and held stably. After the game, it can be laid down and reset, and the chess pieces can be stored in the hollow space of the chess box. The two chess boxes are folded along the hinge and locked by the locking structure, forming a complete closed loop of use from unfolding for the game to folding for storage. The entire chess set is compact and not easy to scatter after storage, making it suitable for carrying around. 2. This invention designs the chess pieces as polygonal structures and installs magnets with the same magnetic pole orientation on each side. The chess pieces can be placed flat on the bottom to achieve open chess games, or placed upright on the side to achieve information concealment in hidden chess games. After moving or capturing a piece, the piece is placed down to reveal the information. Without relying on any electronic components, this invention solves the problem of information visibility control in hidden chess and confrontation chess games on a physical chessboard with a purely mechanical structure.

[0027] 3. By setting the first and second chessboards as double-sided structures, one side is for international chess and the other side is for Chinese chess. Combined with the single-sided open hollow structure of the fixed surface of the chessboard, the user only needs to pull out the chessboard, flip it over and reset it to complete the switching between the two chess systems on the same set of chess equipment. There is no need to purchase and carry a second set of chess equipment, which reduces the cost of use and improves portability. Attached Figure Description

[0035] The following non-limiting embodiments are intended to enable those skilled in the art to gain a more comprehensive understanding of the present invention, but do not limit the invention in any way. The following content is merely an exemplary description of the scope of protection claimed by the present invention, and those skilled in the art can make various changes and modifications to the present invention based on the disclosed content, and such changes should also fall within the scope of protection claimed by the present invention.

[0036] The present invention will be further described below by way of specific embodiments. Unless otherwise specified, all instruments, devices, equipment, reagents, products, etc., used in the embodiments of the present invention are obtained through conventional commercial means.

[0037] Example 1 like Figures 1-6 As shown, this invention provides a foldable, liftable, and modular magnetic chess set suitable for both Chinese and international chess, comprising a chess box 1, a chessboard 2, and chess pieces 5. The chess box 1 includes a first chess box and a second chess box that are symmetrically connected by a hinge. When folded, they form a closed box; when unfolded, they constitute a complete playing platform. The chessboard 2 includes a first chessboard and a second chessboard. The two sides of the chessboard 2 are respectively configured with a first chess layout and a second chess layout. Specifically, one side is a chess layout, and the other side is a Chinese chess layout. The chess layout can be switched by pulling out the chessboard 2, flipping it, and then resetting it. The top surfaces of the first and second chess boxes are respectively provided with borders 3. The first chess box's border is connected to a fixed surface of the first chessboard via a rotating structure 7, and the second chess box's border is connected to a fixed surface of the second chessboard via the rotating structure 7. The first and second chessboard fixing surfaces are both hollow structures with openings on one side, allowing the chessboard to be inserted or removed. Both the first and second chessboard fixing surfaces near the top of the box are made of transparent material. Stainless steel is fixed to one side of each surface, and a magnetic piece is installed at the bottom of each chess piece. When a chess piece is placed on the chessboard fixing surface 4, the magnetic piece attracts the stainless steel, ensuring the piece is stably attached to the surface and doesn't slip. In use, rotating structure 7 raises the chessboard fixing surface 4 from inside the box to the operating angle, unfolding the board for play. When not in use, the chessboard fixing surface 4 is laid down, and the two boxes are folded and snapped shut for storage.

[0038] In one specific embodiment of this example, the interiors of the first and second chess boxes are hollow structures used to store the chess pieces 5. That is, when the chess boxes are folded and closed, the hollow interior space can accommodate all the chess pieces, and the chess boxes also serve as storage boxes, eliminating the need for additional chess piece storage containers.

[0039] In one specific embodiment of this example, the rotating structure 7 is a damping shaft. The damping shaft connects the frame 3 and the chessboard fixing surface 4. When the chessboard fixing surface 4 rotates around the damping shaft, it is subjected to a damping torque, which enables it to maintain itself at any angle after being raised, and can maintain a stable operating posture without additional locking.

[0040] In one specific embodiment of this invention, the rotating structure 7 is a cylindrical shaft with a fixing block on one side. The fixing block has multiple protrusions, and the first and second chessboard fixing surfaces each have protrusions that match the fixing block. When the chessboard fixing surface 4 rotates around the shaft, the protrusions on the chessboard fixing surface 4 engage sequentially with the protrusions on the fixing block, allowing the chessboard fixing surface 4 to achieve segmented positioning at several preset angles.

[0041] In one specific embodiment of this invention, the rotating structure is a rotating connecting rod 16. The frame 3 is provided with grooves that match the rotating connecting rod 16. The first end of the rotating connecting rod 16 is fixedly connected to the midpoint of the side of the chessboard fixing surface 4, and the second end of the rotating connecting rod 16 is slidably connected to the groove. Multiple support points are provided inside the groove. During the raising and lowering of the chessboard fixing surface 4, the second end of the connecting rod slides along the groove. When it slides to different support points, it forms a locking position, allowing the chessboard fixing surface 4 to obtain stable support at multiple height positions.

[0042] In one specific embodiment of this invention, a snap-on button 6 is provided on the frame 3, a support structure 13 is provided on one side of the inside of the chess box, a spring assembly 14 is provided inside the support structure 13, and a protruding structure 15 matching the snap-on button 6 is provided on one side of the chessboard fixing surface 4. In the stored state, the snap-on button 6 and the protruding structure 15 engage with each other, locking the chessboard fixing surface 4 inside the chess box 1; after pressing the snap-on button 6 to release the engagement, the spring assembly 14 provides elasticity to spring the chessboard fixing surface 4 to the operating position, realizing quick opening.

[0043] In one specific embodiment of this example, a rigid fixing structure 8 is provided on the side of the chessboard fixing surface 4 near the inside of the chess box. The rigid fixing structure 8 includes multiple square frames 9, and multiple interconnected hexagonal structures 10 are provided inside the square frames 9. The rigid fixing structure 8 is made of plastic. That is, a honeycomb plastic skeleton is attached to the back of the chessboard fixing surface 4, which improves the overall rigidity and flatness of the chessboard fixing surface 4 without significantly increasing the weight, and prevents bending and deformation during use.

[0044] In one specific embodiment of this invention, a stainless steel piece 11 is provided inside the chessboard fixing surface 4 near the inside of the chess box. The stainless steel piece 11 has a square structure, and multiple pieces are arranged sequentially at preset intervals to cover the entire chessboard fixing surface 4. The multiple square stainless steel pieces 11 evenly cover the entire board surface area, ensuring that each placement position on the board can generate a stable magnetic force with the magnetic piece 5, guaranteeing reliable positioning of the chess piece 5 at any location.

[0045] In one specific embodiment of this invention, the chess piece 5 is a polygonal chess piece with a non-circular cross-section. Each side of the polygonal chess piece is equipped with a magnetic piece, and the magnetic properties of the magnetic pieces facing outwards are the same. Specifically, the cross-section of the chess piece can be a regular hexagon. The hexagonal chess piece can be placed flat on the board to achieve an open chess state, that is, the information label face is upward and visible to both players; or it can be placed on the board with any side facing outwards to achieve a hidden chess state, that is, the information label face is facing to the side and cannot be identified by the opponent. Since the magnetic poles on the outer sides of the magnetic pieces on each side are consistent, the chess piece 5 can stand stably with the stainless steel 11 on the fixed surface 4 of the chessboard, regardless of which side it is placed on, and this can prevent the chess pieces from attracting each other and causing them to become displaced.

[0046] In one specific embodiment of this example, the first chess box and the second chess box are respectively provided with handles 17 on their outer sides, and the first chess box and the second chess box are respectively provided with matching locking structures 12 on their outer sides. The handles 17 make it easy for users to hold and carry, and the locking structures 12 securely lock the two chess boxes after they are folded and closed, preventing the chess pieces 5 from being accidentally opened and scattered during carrying.

[0047] The working principle of this device is as follows.

[0048] Before use, the entire chess set is folded and stored. The first and second chess boxes are folded and fastened together by hinges, and the locking structure fixes the two chess boxes into one unit. All the chess pieces are stored in the hollow space inside the chess box, and the chessboard is placed flat on the top of the chess box, forming a closed box that is easy to carry.

[0049] To begin use, release the locking mechanism and unfold the first and second chess boxes along the hinges to a flat state. Depending on the selected chess game, pull out the first and second chessboards from the openings on one side of their mounting surfaces, flip them to the desired chess game side, and then reinsert them into their mounting surfaces. If chess is selected, place the chessboard side up; if Chinese chess is selected, flip it so the Chinese chess side is up. After resetting the chessboards, use the rotating mechanism to raise both the first and second chessboard mounting surfaces from the boxes to a suitable operating angle. The rotating mechanism uses damping shafts, interlocking cams, or linkage support points to ensure the chessboard mounting surfaces remain stable after being raised. If the chess box is equipped with a snap-on button and spring assembly, pressing the button will spring the chessboard mounting surfaces up. The two chessboard mounting surfaces, once raised, can be joined to form a complete chessboard.

[0050] During the placement phase, the pieces are taken from the game box. In open-chess mode, both players place their pieces flat on the board with the information label side facing up, making all pieces visible to both players. In hidden-chess mode, each player places their piece upright on the board with the information label side facing away, making the opponent unable to identify the piece. The magnetic plate on the bottom of the piece engages with the stainless steel plate on the board, ensuring stable adhesion whether the piece is placed flat or upright. Each polygonal piece has a magnet with the same magnetic pole orientation on each side, ensuring reliable magnetic positioning regardless of its upright position. In confrontation mode, the first player places one piece, and then both players take turns placing two pieces each until all pieces are placed.

[0051] During the game phase, in open chess mode, both players move their pieces according to the standard rules. In hidden chess mode, after a player makes a move or captures a piece, the piece is changed from a standing position to a flat position, revealing its identity to the opponent. After the pieces are placed in a standoff, both players can choose to continue playing hidden chess or turn all their pieces upside down to play open chess.

[0052] After the game, lay the chessboard back into the box, put all the pieces back into the empty space inside the box, fold the first and second boxes together along the hinges, lock the structure, and restore the portable storage state.

[0053] Example 2 This invention also provides a method for playing a foldable, liftable, and modular magnetic chess set suitable for both middle and high school students, comprising the following steps: S1: Determine the orientation of the chessboard according to the selected chess system, pull the chessboard out from the fixed surface of the chessboard, flip it to the corresponding chess system surface and then reset it so that the fixed surface of the chessboard presents the selected chess system pattern. S2: Select the corresponding piece from the pieces according to the selected game mode. If the open game mode is selected, all pieces are placed on the fixed surface of the board in the first placement state to complete the placement. If the hidden game mode is selected, both players place their own pieces on the fixed surface of the board in the second placement state, so that the information labels of the pieces of both players are not visible to each other. S3: In the Dark Chess mode, when one side makes a move or captures a piece, the piece is changed from the second placement state to the first placement state, making the piece's information identifier visible to both sides.

[0054] Furthermore, S2 also includes a confrontation chess placement mode: the first player places one piece, and then the two players take turns placing two pieces each until all pieces are placed; after the pieces are placed, the two players can choose to continue playing in the hidden chess mode, or change all pieces to the first placement state to switch to the open chess mode.

[0055] Verification of technical effectiveness and / or analysis of technical problem solving This invention simplifies game mode switching to three actions—pulling out, flipping, and resetting—using a double-sided chessboard with a hollow, single-sided opening as a fixing surface. This eliminates the need to replace the individual chessboard board, thus avoiding the problems of carrying or losing spare parts. By installing magnets with aligned magnetic poles on each side of the polygonal chess pieces, the information display face is invisible and magnetically stable when the pieces are placed upright on their side, and is revealed when the bottom is flat. This physical change in placement achieves both concealment and directional reveal of hidden game information without electronic components, filling a gap in information visibility control in existing physical chessboards. The combination of a rotating and lifting chessboard fixing surface, the storage of chess pieces in the hollow chess box, and a hinged folding and locking structure allows for rapid transition between playing and storage states. The folded structure is closed and compact, preventing pieces from falling out or scattering during transport. These three technical measures address the issues of dual game mode switching, hidden game information control, and integrated portable storage, forming a complete closed-loop technical solution.

[0056] Finally, it should be noted that the above content is only used to illustrate the technical solution of the present invention, and is not intended to limit the scope of protection of the present invention. Simple modifications or equivalent substitutions made by those skilled in the art to the technical solution of the present invention do not depart from the essence and scope of the technical solution of the present invention.
