1 56 FIGS.to 1000 1000 100 1000 10 20 10 30 10 20 50 20 30 10 30 1000 30 10 30 10 As shown in, schematic views of the jigsaw puzzle tablefrom a first embodiment of the present invention are presented. The jigsaw puzzle tableis designed for a user or player to assemble a plurality of puzzle piecesthereon. Accordingly, the jigsaw puzzle tablecomprises a board assembly, a supporting portionlocated below the board assembly, a supporting assemblysupporting the board assemblyand the supporting portion, and an adjusting structurehinged to both the supporting portionand the supporting assemblyfor adjusting a positional relationship between the board assemblyand the supporting assembly. The jigsaw puzzle tablecan be placed in any playing space, such as on a table, wall, floor, or similar structure. The supporting assemblycan support the board assemblyrelative to the playing space. The height of the supporting assemblyis adjustable, which allows for changing a distance of the puzzle board assemblyfrom the user.

10 1 200 40 1 1 40 1 1 The board assemblycomprises a puzzle boardfor placing a plurality of puzzle piecesand a rotating assemblyattached to the puzzle boardfor supporting the puzzle board. The rotating assemblydrives the puzzle boardto rotate in any direction, thereby changing positions of the puzzle boardrelative to the user.

200 200 200 200 Due to the need to assemble the puzzle piecesinto a complete image, it is essential for an orientation of the puzzle piecesto be aligned with the user's viewpoint to facilitate more effective puzzle operations. In a related jigsaw puzzle table, the positioning of the jigsaw puzzle table is fixed, meaning it only offers a specific puzzle position that is regarded as an optimal viewpoint. When the size of the jigsaw puzzle table exceeds the user's arm length, making it impossible to reach the puzzle pieceslocated on the opposite side of the optimal viewpoint, the user has to walk around to assembly the puzzle piecesand then return to the original optimal viewpoint. In this situation, users are forced to adapt to the structural characteristics of the product, which significantly diminishes their experience of using the jigsaw puzzle table.

40 1000 200 1000 200 40 1000 The present invention provides the rotating assembly, allowing the orientation of the jigsaw puzzle tableto be adjusted flexibly. This means that the optimal viewpoint can be adjusted in real-time according to the location of the user currently working on the puzzle pieces, without requiring the user to move. Particularly during collaborative sessions involving multiple users, this rotatable design enables different users to switch their optimal viewpoint of the jigsaw puzzle table, allowing each user to maintain the optimal viewpoint, which significantly enhances both efficiency and user experience. Furthermore, when the jigsaw puzzle tableis large, the optimal viewpoint on the opposite side can also be rotated to face the user directly. After accessing the puzzle pieces, the user can rotate it back to its original position without needing to walk around. Therefore, the rotating assemblyfundamentally alters the structural characteristics of the related jigsaw puzzle table, enabling the product to adapt to user habits and greatly improving the overall user experience.

1 11 12 11 11 12 20 20 20 40 11 11 11 11 The puzzle boardcomprises a puzzle plateand a fixing framesupporting the puzzle plate. The puzzle plateis fixed by the fixing frameat a distance from the supporting portion, serving as a game area for assembling the puzzle piecesand where users perform their puzzle operations. In other words, both the supporting portionand the rotating assemblyare located on a back side of the puzzle plate. The puzzle plateis a rectangular planar structure that comprises two longer edgesA extending along a longitudinal direction X and two shorter edgesB extending along a lateral direction Y. The longitudinal direction X is perpendicular to the lateral direction Y.

12 121 122 121 123 122 121 11 122 123 11 12 121 11 121 124 122 124 121 11 124 124 124 11 124 11 12 11 12 11 12 The fixing framecomprises a fixing portion, a hollow spacesurrounded by the fixing portion, and a reinforcing portionlocated within the hollow spaceand connected to the fixing portion. The puzzle plateis received in the hollow spaceand is supported by the reinforcing portion. The puzzle plateand the fixing framecan be assembled together using threads, snap-fit, friction fit, screws, rivets, ultrasonic welding, adhesive bonding or other similar methods. The fixing portionis a rectangular circular structure that matches the shape of the puzzle plate, thereby enhancing the overall coordination of the product. The fixing portioncomprises a fixing slotthat communicates with the hollow space. The fixing slotextends linearly from one end of the fixing portionto the other. The puzzle platecan be inserted from either end of the fixing slot, with its edges constrained within the fixing slot. The fixing slotrestricts the lateral and horizontal movement of the puzzle plate, allowing its motion to occur only along the extension direction of the fixing slot. Therefore, there is no need for additional fixing structures between the puzzle plateand the fixing frame, while still maintaining a detachable connection between them. This allows the puzzle plateand the fixing frameto be packaged separately for transportation, addressing the potential issue of damage during transport when the puzzle plateis assembled onto the fixing frame.

121 121 121 124 121 11 11 124 121 11 121 11 11 124 121 121 1201 1202 1201 1202 1201 11 200 The fixing portioncomprises two longer sidewallsA extending along the longitudinal direction X and two shorter sidewallsB extending along the lateral direction Y. The fixing slotis located on the longer sidewallsA and is designed to accommodate the longer edgeA of the puzzle plate. The fixing slotson the two longer sidewallsA are positioned at the same horizontal height to ensure that the puzzle plateis in a flat position relative to the fixing portionafter installation, meaning that the puzzle plateis horizontally placed with respect to the playing space or the user's perspective. Of course, if it is desired for the puzzle plateto be installed at a slight angle, the fixing slotson the two longer sidewallsA can also be positioned at different horizontal heights. Each longer sidewallA comprises an extending walland a main supporting wallextending downwardly from the extending wall. The extending wallis integral with the main supporting wallas a whole. The extending wallis cooperated with puzzle platefor forming the game area for placing the plurality of puzzle pieces.

121 1210 1210 1210 18 121 1210 In this embodiment, the fixing portionis composed of multiple fixing unitsthat are spliced together. Preferably, the multiple fixing unitsare arranged along the longitudinal direction X, and two adjacent fixing unitsare connected in a detachable manner via a hinge assembly. This design allows the fixing portionto be disassembled into several fixing units, which can be stacked for packaging and transportation, thereby reducing an overall volume of the jigsaw puzzle table.

121 11 110 110 124 1210 110 11 121 1210 11 110 110 1210 To facilitate the disassemblable structure of the fixing portion, the puzzle platecan also be configured to consist of multiple plate unitsthat are spliced together. During installation, the multiple plate unitscan be inserted one by one into the fixing slot. Similar to the fixing units, the plate unitscan also be stacked for packaging and transportation, minimizing the volume occupied by the puzzle plate. Specifically, in this embodiment, the fixing portionis formed by two symmetrical fixing units, while the puzzle plateis composed of two symmetrical plate units. The number of plate unitsand fixing unitsis not limited to two and can be greater.

18 182 181 182 183 182 1210 18 1210 1210 181 1210 1210 1210 1 19 1210 18 18 19 18 19 18 1210 1210 1210 56 FIG. The hinge assemblycomprises a pair of hinge plates, a pin shaftconnected to the pair of hinge plates, and a pair of fixed screwssecured the hinge platesto a corresponding fixing unit. The hinge assemblyis positioned on a top surface of the fixing unitsand is used to connect two adjacent fixing units, allowing them to rotate around the pin shaft. This enables one fixing unitto move toward the other fixing unitto form a fold, or for both fixing unitsto move toward each other to create a fold. Referring to, the puzzle boardfurther comprises a receiving slotformed on two adjacent fixing unitsfor receiving the hinge assembly. When the hinge assemblyis received within the receiving slot, the hinge assemblyis fully embedded in the receiving slot, with the upper surface of the hinge assemblyflush with or lower than the top surfaces of the fixing units. When two adjacent fixing unitsare folded and assembled towards each other, the top surfaces of the two adjacent fixing unitsare directly stacked on top of each other.

123 11 40 40 11 The reinforcing portionis capable of supporting the puzzle plateand offering a mounting position for the rotating assembly. Optionally, the rotating assemblycan also be directly attached to a bottom of the puzzle plate.

123 121 11 The reinforcing portionis connected to the fixing portioneither directly or indirectly and can be arranged in any direction, such as along the longitudinal direction X or along the lateral direction Y. Preferably, multiple reinforcing portions are arranged in an interlaced manner along both the longitudinal direction X and the lateral direction Y to provide a more stable supporting effect for the puzzle plate.

123 1231 1232 1231 1231 1232 123 1231 121 124 121 124 1232 121 1231 121 1232 121 In this embodiment, the reinforcing portioncomprises a first reinforcing armextending along the longitudinal direction X and a second reinforcing armextending along the lateral direction Y and interlaced with respect to the first reinforcing arm. Both the first reinforcing armand the second reinforcing armserve as a core framework of the reinforcing portion. The two ends of the first reinforcing armare aligned with the two shorter sidewallsB and are spaced apart from the fixing slot, positioned below the shorter sidewallsB to avoid interfering with the fixing slot. The two ends of the second reinforcing armare fixed to the two longer sidewallsA. Preferably, the ends of the first reinforcing armare located below midpoints of the two shorter sidewallsB, while the ends of the second reinforcing armare fixed to midpoints of the two longer sidewallsA.

123 1233 1231 1232 1234 1232 1231 1233 1231 1234 1232 1233 1234 1234 121 The reinforcing portionfurther comprises a third reinforcing armparallel to the first reinforcing armand interlaced with respect to the second reinforcing arm, and a fourth reinforcing armparallel to the second reinforcing armand interlaced with respect to the first reinforcing arm. The two third reinforcing armsare symmetrically distributed on either side of the first reinforcing arm, and the two fourth reinforcing armsare symmetrically distributed on either side of the second reinforcing arm. The ends of the third reinforcing armare fixed to the two fourth reinforcing arms, and the ends of the fourth reinforcing armare fixed to the two longer sidewallsA.

11 1233 1234 11 200 The central area of the puzzle platehas the highest degree of freedom, making it prone to collapse. The setting of the third reinforcing armand the fourth reinforcing armprovides better support for the central area of the puzzle plate, increasing its load-bearing capacity for the puzzle piecesand allowing it to accommodate a larger number of puzzle pieces, such as 1000, 1500, or other high-capacity quantities.

121 1231 1234 13 121 1200 13 13 121 13 14 11 13 1200 121 1231 1238 14 1238 124 The longer sidewallA, the first reinforcing arm, and the fourth reinforcing armform the drawer cavity. Each shorter sidewallB comprises two drawer openingscommunicated with the drawer cavity. One end of the drawer cavityis aligned with the shorter sidewallB, and the drawer cavityreceives the puzzle drawer, which is located beneath the puzzle plateand can be moved within the drawer cavityto open or close through drawer openings. Specifically, the longer sidewallA and the first reinforcing armare also equipped with a drawer slotthat extends along the longitudinal direction X and allows for the movement of the puzzle drawer; the drawer slotis positioned below the fixing slot.

14 200 200 14 11 14 200 14 14 10 10 1 15 15 151 152 151 121 14 152 151 151 152 14 12 The puzzle drawerserves as a storage space for the puzzle pieces, allowing the puzzle piecesto be stored inside the puzzle drawer. The puzzle platecloses off a top opening of the puzzle drawer, making it difficult for the puzzle piecesto fall out from within the puzzle drawer. To prevent movement of the puzzle drawerwhen closed especially during the user's movement or rotation of the board assembly, or when the board assemblyis tilted. The puzzle boardfurther comprises a drawer locking member. The drawer locking membercomprises a locking partand a coupling partfitting together with the locking part, with one of them fixed to the shorter sidewallB and the other fixed to the puzzle drawer. The coupling partlocks the locking partin place, preventing relative movement between the locking partand the coupling part, thereby restricting the movement of the puzzle drawerrelative to the fixing frame.

11 121 14 15 11 30 31 32 Since the puzzle plateis located between the shorter sidewallB and the puzzle drawer, the drawer locking memberalso creates limits at both ends of the puzzle plate, restricting its movement along the longitudinal direction X. The supporting assemblycomprises a board bracketand a supporting structure

31 31 31 10 311 312 313 314 314 312 312 311 312 313 310 314 positioned below the board bracketfor supporting the board bracket. The board bracketis spaced apart from the board assemblyand comprises a first supporting member, a second supporting member, a third supporting member, and a connecting shaft, which are sequentially connected to form a closed frame. The connecting shaftis located opposite the second supporting memberand is arranged parallel to the second supporting member. The first supporting member, the second supporting member, and the third supporting membertogether form a main framefor supporting the connecting shaft.

20 21 30 22 21 22 30 20 30 The supporting portioncomprises a connecting portionconnected to the supporting assembly, and an extending portionextending from the connecting portion. The extending portionis detachably supported on the supporting assembly. The supporting portioncan be in either an open state or a closed state relative to the supporting assembly.

20 22 30 10 11 20 22 30 20 10 30 11 10 11 20 11 When the supporting portionis in the closed state, the extending portioncontacts the supporting assembly, allowing the board assemblyto be positioned horizontally and supporting the puzzle platein a horizontal state. Conversely, when the supporting portionis in the open state, the extending portionseparates from the supporting assembly, causing the supporting portionto incline the board assemblyrelative to the supporting assembly. At this time, the puzzle plateof the board assemblyalso tilts relative to the user, which support the puzzle platein an inclined state. Therefore, the supporting portionis capable of allowing the puzzle plateto switch between the inclined state and the horizontal state.

22 20 21 20 314 314 314 21 314 The extending portionis elongated and may be hollow inside to reduce a weight of the supporting portion, which is made of metal material. The connecting portionof the supporting portionis movably connected to the connecting shaftand is capable of freely rotating around the connecting shaft. Specifically, the connecting shafthas a cylindrical structure, while the connecting portionis a ring sleeve that fits over an outer circumference of the connecting shaft. The ring sleeve can be either fully enclosed or semi-enclosed.

314 21 21 21 314 21 314 20 10 21 314 When the ring sleeve has a semi-enclosed structure, the connecting shaftis detachably coupled with the connecting portion. This configuration allows the connecting portionto takes on a circular tubular shape with an opening, ensuring that the connecting portioncan rotate around the connecting shaftwhile also facilitating easy disassembly and assembly between the connecting portionand the connecting shaft. The supporting portionand the board assemblycan be detached from the opening of the connecting portionwithout being restricted by the connecting shaft.

20 10 20 10 30 314 The supporting portioncan independently support the board assembly, allowing both the supporting portionand the board assemblyto be placed directly on any playing surface, such as a table, wall, floor, or similar structure, or on a carrier with a certain height, thus eliminating the need for the supporting assembly. When the ring sleeve is a closed structure, it can be fitted onto either end of the connecting shaft.

20 20 312 314 20 31 30 10 20 10 The number of supporting portionsis two, and the two supporting portionsare symmetrically arranged about a line connecting midpoints of the second supporting memberand the connecting shaft. This arrangement ensures that the two supporting portionsare symmetrically positioned relative to the board bracket, while the supporting assemblyis coaxially aligned with the center of gravity of the board assembly, ensuring that both supporting portionsare also symmetrically arranged relative to the board assembly.

20 10 20 10 10 200 10 20 The two supporting portionsexert a stronger driving force on the board assembly, allowing it to move more smoothly. Additionally, these two supporting portionscan apply uniform support forces at both ends of the board assembly, ensuring balanced loading on the board assembly. This is especially important when the number of puzzle piecesis 1500 or 2000, as the size of the board assemblyincreases. In such cases, the two supporting portionscan provide a more stable support effect.

1000 24 314 21 24 240 314 241 240 242 241 240 2410 The jigsaw puzzle tablefurther comprises a positioning portionattached to the connecting shaftto control a distance between the two connecting portions. The positioning portioncomprises a positioning partattached to the connecting shaft, a positioning sleevefitted onto the positioning part, and a positioning pinsecured to the positioning sleeve. The positioning partcomprises a positioning opening.

240 21 314 22 20 241 240 2410 The positioning partis located between the two connecting portions, preventing them from moving toward each other on the connecting shaft, which could affect the inclination of the extending portionand subsequently impact the lifespan of the supporting portion. The positioning sleeveis detachably fitted onto the positioning partvia the positioning opening.

242 241 240 314 314 240 20 242 241 240 314 2410 The positioning pinis used to secure the positioning sleeve, positioning part, and connecting shaftin an axial direction of the connecting shaft, thereby limiting the axial movement of the positioning partand the supporting portion. The positioning pinis inserted into the positioning sleeve, the positioning part, and the connecting shaft, and is protruded from the positioning opening.

314 3140 241 240 242 3140 240 241 314 Additionally, the connecting shaftis provided with an inserting hole. When the positioning sleeveis placed onto the positioning part, the positioning pincorresponds to and is inserted into the inserting hole, achieving an axial fixation of the positioning part, positioning sleeve, and connecting shaft.

312 3120 20 20 20 22 21 3120 11 The second supporting membercomprises a receiving portioncorresponding to the supporting portion. When the supporting portionis in the closed state, a movable end of the supporting portion, which refers to the end of the extending portionthat is farthest from the connecting portion, is engaged within the receiving portionto maintain the horizontal state of the puzzle plate.

32 321 31 322 321 323 321 322 321 322 323 10 The supporting structurecomprises an upper bracketconnected to the board bracket, a lower bracketpositioned below the upper bracket, and an adjusting bracketconnected to both the upper bracketand the lower bracket. All three components-the upper bracket, lower bracket, and adjusting bracket-extend vertically to provide the necessary height for the board assembly.

323 3231 3232 3233 32 The adjusting bracketcomprises a supporting rod, a supporting sleeve, and an adjustment rod. These components work together to allow for height adjustments and structural stability of the supporting structure.

3231 321 322 321 322 30 3231 321 322 323 The supporting rodis movably connected between the upper bracketand/or the lower bracket, allowing for the adjustment of the distance between these two bracketsand, thereby altering the overall height of the supporting assembly. Specifically, the supporting rodhas a hollow cylindrical structure. The upper bracketand/or the lower bracketcomprise guiding passages. The end of the adjusting bracketis received within the guiding passages and can move freely inside them.

3232 3231 321 322 30 The supporting sleeveis fitted over an outer circumference of the supporting rodand is fixed to either the upper bracketor the lower bracket. This configuration allows for enhanced stability and ease of adjustment in maintaining the desired height of the supporting assembly.

3231 3234 3231 3231 3234 3231 The supporting rodcomprises a plurality of first positioning holespenetrated through a sidewall of the supporting rodand communicated with a hollow interior of the supporting rod. The first positioning holesare evenly spaced along an axial direction of the supporting rod.

3232 3235 3231 3234 3235 3231 3233 3235 3234 3231 3232 3231 The supporting sleevecomprises a second positioning hole. By moving the supporting rodup or down, when a desired first positioning holealigns with the second positioning hole, it indicates that the supporting rodmeets an expected height requirement. At this point, the adjustment rodis sequentially inserted into the second positioning holeand the aligned first positioning hole, which secures the supporting rodto the supporting sleeveand restricts any axial movement of the supporting rod, thereby maintaining a desired set position.

40 20 10 40 41 20 42 41 10 1 1 41 42 The rotating assemblyis sandwiched between the supporting portionand the board assembly. The rotating assemblycomprises a first moving membermounted on the supporting portionand a second moving memberrotatably coupled with the first moving memberand mounted on the board assembly. When it is necessary to adjust the orientation of the puzzle board, a driving force is applied to the puzzle board, allowing it to rotate relative to the first moving memberunder the guidance of the second moving member.

1 1 2 1 1 2 200 1 200 1000 1 200 The rotation angle of the puzzle boardcan be any angle. For example, during a two-person puzzle session, user Pand user Pare positioned at opposite sides of the puzzle board. When there is a need to transfer control from user Pto user Pfor assembling the puzzle pieces, the puzzle boardcan simply be rotated 180 degrees either clockwise or counterclockwise. Additionally, users can assemble puzzle pieceson one side of the jigsaw puzzle tableand then rotate the puzzle boardby 180 degrees to work on another set of puzzle pieceson the other side, thereby expediting the assembly process.

10 1 40 1 1 40 43 41 42 43 41 42 1 20 41 42 It should be noted that the rotation angle of the board assemblycan be adjusted to be less than 360 degrees, providing flexibility in how the puzzle boardis oriented for ease of use. The rotating assemblyis coaxially coupled with a center of mass of the puzzle board, allowing the puzzle boardto rotate in a balanced manner, ensuring its stability during operation. The rotating assemblyfurther comprises a rotor mechanismrotatably positioned between the first moving memberand the second moving member. The rotor mechanismserves as a connecting medium between the first and second moving membersand, effectively spacing them apart. This configuration allows the puzzle boardto rotate smoothly in various planar directions relative to the supporting portion. This design transforms a frictional interaction between the first moving memberand the second moving memberfrom sliding friction to rolling friction. As a result, the friction damping between these two components is significantly reduced, providing a smoother rotation experience for the user.

43 431 432 431 431 432 432 41 42 The rotor mechanismcomprises a retainer unitand a plurality of ball-shaped rotorsthat are rotatably retained within the retainer unit. The retainer unitis configured to spacedly retain the plurality of rotorsin a rollable manner, allowing each rotorto freely roll on both the first moving memberand the second moving member.

In this embodiment, the first coupling baseis an integral annular structure that completely surrounds the first rolling portion. In an alternative embodiment, the number of first coupling bases can be multiple, spaced apart from each other by a certain distance. This design allows for greater flexibility and adaptability, enabling adjustments to the number and layout of coupling bases according to actual needs, thereby optimizing the performance and stability of the rotating assembly.

The board assemblyis mounted on the extending portionof the supporting portionthrough the first coupling unit. The rotation of the connecting portiondrives the supporting portionto rotate, causing the supporting portionto tilt relative to the board bracket. Since the board assemblyis fixed relative to the supporting portion, when the supporting portiontilts, the board assemblywill also tilt synchronously. This allows the board assemblyto face the user more effectively, facilitating puzzle operations.

10 21 314 21 21 10 21 When the user lifts the board assemblywith external force, the connecting portioncan rotate around the connecting shaft, making it easier for the user to operate. The connecting portioncan also be configured as a hinge, magnetic structure, or other similar rotating connection components, as long as it ensures that the connecting portionprovides sufficient support and guidance for the board assemblywhen it tilts. Preferably, the connecting portionhas a self-locking function.

The sliding armsextend in the direction of the extension of the sliding slot. The pair of sliding armsand the sliding portioncooperatively form a sliding spacethat accommodates the free endB of the driving unitand the guiding unit. The sliding portionis positioned at one end of the sliding arms, closer to the second fastening unitthan to the free endB of the driving unit, and is spaced apart from the free endB of the driving unitto prevent the driving unitfrom contacting the sliding portionand the sliding armsduring the movement of the driving unit. One end of the guiding unitis fixed to the sliding portion, while the other end of the guiding unitextends away from the sliding portionand is detachably pivoted to the driving unit.

The first extending portionis located close to the sliding portion, while the second extending portionis located away from the sliding portion. The first extending portionand the second extending portioncooperate with the base portionto form a guiding portion. The guiding portionis provided on both sides of the base portionand serves to guide the movement of the driving unit.

52 521 522 521 523 521 521 523 52 523 523 5334 52 523 5334 The driving unitcomprises a pair of third pivoting partsarranged in parallel with a gap between them, a third connecting partconnected to the two third pivoting parts, and a pair of guiding membersprotruded from one third pivoting parttoward the direction of the other third pivoting part. Each guiding membersis arranged on the free endB, and the pair of guiding membersare spaced apart. Each guiding membermatches with the guiding portion, and the states of the driving unitare adjusted by the relative position between the guiding memberand the guiding portion.

533 5335 5332 5333 5335 5334 5336 5337 5337 5332 5331 5335 5336 5333 5335 5337 5123 5336 The guiding unitfurther comprises a position switching partprotruded from the first extending portiontowards the second extending portion. The position switching partdivides the guiding portioninto a position switching grooveand a position retaining groove. The position retaining grooveis enclosed by the first extending portion, the base portion, and the position switching part. The position switching grooveis formed between the second extending portionand the position switching part. The position retaining grooveis situated further away from the sliding slotcompared to the position switching groove.

5336 523 5337 5123 5123 5337 523 5337 5123 52 5335 50 The position switching grooveserves as a transition channel, enabling the guiding memberto move from the position retaining grooveto the sliding slot, or vice versa, from the sliding slotback to the position retaining groove. When the guiding memberis located between the position retaining grooveand the sliding slot, the positions and states of the driving unitdiffer. Preferably, the top surface of the position switching partis designed to be smooth to enhance the smoothness during the position switching process and to prevent jamming. The adjusting structurecomprises three states: the sliding state, the locked state, and the folded state.

533 5123 511 512 52 511 512 52 533 5122 In the folded state: the guiding unitis located at the starting end of the sliding slot, with both the first adjusting armand the second adjusting armfolded and closed. The driving unitis accommodated at a smaller inclination angle between the first adjusting armand the second adjusting arm, while the free endB is stored underneath the guiding unit, in close contact with the second connecting part.

52 5125 52 10 511 512 511 512 20 10 52 511 512 1000 10 In the locked state: the free endB is locked in any of the locking slots, and the driving unitis inclined with respect to the board assembly, which restricts the folding and closing of the first adjusting armand the second adjusting arm. This allows both the first adjusting armand the second adjusting armto maintain a continuous stable state, thereby keeping the supporting portionand the board assemblyinclined. It can be understood that in the locked state, the driving unit, the first adjusting arm, and the second adjusting armform a triangular stable structure, which further enhances the stability of the jigsaw puzzle tablewhen the board assemblyis inclined.

52 5337 5335 52 5123 5336 5122 5125 52 523 5337 5332 5333 5123 533 5123 In the sliding state: the free endB is retained within the position retaining groove. Due to the limiting effect of the position switching unit, the free endB cannot enter the sliding slotthrough the position switching groove, which prevents it from contacting the second connecting partand entering the locking slots. As the driving unitmoves up and down, the guiding memberis received in the position retaining grooveand drives either the first extending portionor the second extending portionto move within the sliding slot, causing the guiding unitto slide linearly along the sliding slot.

52 5334 20 10 52 52 53 5123 5123 20 10 523 5336 5335 523 5337 20 10 52 523 52 5332 5335 5337 52 53 5123 52 53 5123 5123 523 5336 523 5336 5123 Switching process from the folded or locked state to the sliding state: in the folded or locked state, the free endB separates from the guiding portion. The user can lift the supporting portionor the board assemblywith their hand, thereby driving the driving unitupwards. During this movement, the driving unitcauses the control unitto move linearly up along the sliding slotuntil it reaches the end of the sliding slot. As the user continues to lift the supporting portionor the board assembly, at least one guiding membercan enter the position switching groove. After passing the position switching unit, at least one guiding memberenters the position retaining groove, achieving the sliding state. At this point, when the user presses down on the supporting portionor the board assembly, the driving unitmoves downward to adjust to an appropriate position. Throughout this downward movement, at least one guiding memberof the driving unitremains restricted by the first extending portionand the position switching unit, preventing it from disengaging from the position retaining groove. Therefore, the driving unitwill drive the control unitto slide synchronously down/up along the sliding slot, maintaining the sliding state. In this embodiment, when the driving unitand the control unitmove to the top end of the sliding slot(the end of the sliding slot), the guiding memberis switched into the position switching groove, thereby achieving the sliding state. In an alternative embodiment, the guiding membermay be entered into the position switching grooveat any position along the sliding slot.

523 5337 20 10 52 52 5337 5335 5336 5336 5123 52 5125 Switching process from the sliding state to the locked state: In the sliding state, at least one guiding memberis accommodated within the position retaining groove. At this moment, the user lifts the supporting portionor the board assemblywith their hand, driving the driving unitto move upward. The free endB disengages from the position retaining groove, crosses over the position switching unit, and enters the position switching groove. It then exits from the end of the position switching grooveinto the sliding slot. By fine-tuning the position of the driving unit, it is aligned with the appropriate locking slots, thus entering the locked state.

20 10 52 5125 20 10 20 10 52 52 5123 5123 Switching process from the sliding state to the folded state: First, the user lifts the supporting portionor the board assemblywith their hand, causing the free endB to disengage from the locking slots. Then, by pressing down on the supporting portionor the board assembly, or utilizing the weight of the supporting portionand the board assembly, the driving unitis driven to move downward. The free endB travels along the sliding slotuntil it reaches the starting end of the sliding slot, entering the folded state.

52 541 5334 52 52 5334 As the driving unitrotates around the fourth pivoting shaft, the guiding portionis set to an inclined position to better accommodate the movement trajectory of the driving unit, facilitating the entry and disengagement of the free endB from the guiding portion. This embodiment optimizes the workflow of the mechanical structure, enhancing the smoothness and efficiency of the operation.

20 40 20 10 10 40 20 10 40 10 10 1000 11 The state adjustment process for the supporting portionand the state adjustment process for the rotating assemblyoperate independently. When the supporting portionis closed, the board assemblyis in the horizontal state relative to the user or the playing space. The orientation of the board assemblyin the horizontal state can be altered through the movement of the rotating assembly. When the supporting portionis opened, the board assemblytransitions into the inclined state. Again, the movement of the rotating assemblyallows for changes in the orientation of the board assemblywhile it is in this inclined state. This independent functionality provides users with flexibility in adjusting both the tilt angle and orientation of the board assemblyaccording to their preferences and needs, enhancing the overall usability and adaptability of the jigsaw puzzle tableduring play. Users can easily operate the puzzle plateto switch between the inclined state and the horizontal state while also adjusting the direction of the board assembly for optimal viewing and access.

20 40 10 20 10 40 10 40 10 20 The adjustment process of the supporting portionand the adjustment process of the rotating assemblycan occur in any order. It is possible to first adjust the inclined state of the board assemblythrough the supporting portion, and then adjust the orientation of the board assemblythrough the rotating assembly; alternatively, it is possible to first adjust the orientation of the board assemblythrough the rotating assembly, and then adjust the inclined state of the board assemblythrough the supporting portion.

To prevent the rotation of the puzzle board, the rotating locking portioncan be inserted into the horizontal locking holeto secure this viewing position 20 1 11 121 1 16 172 Horizontal Lateral State: In this state, the supporting portionis closed, the puzzle boardis positioned laterally, and both the shorter edgeB and the shorter sidewallB are directly in front of the user. To prevent the rotation of the puzzle board, the rotating locking portioncan be inserted into the lateral locking holeto secure this viewing position. 39 48 FIGS.- 20 1 11 11 121 12 1 16 171 Inclined Longitudinal State: As shown in, in this state, the supporting portionis open, the puzzle boardis positioned longitudinally, and both the longer edgeA of the puzzle plateand the longer sidewallA of the fixing frameare directly in front of the user. To prevent the rotation of the puzzle board, the rotating locking portioncan be inserted into the horizontal locking holeto secure this viewing position. 49 53 FIGS.- 20 1 11 121 1 16 172 Inclined Lateral State: As shown in, in this state, the supporting portionis open, the puzzle boardis positioned laterally, and both the shorter edgeB and the shorter sidewallB are directly in front of the user. To prevent the rotation of the puzzle board, the rotating locking portioncan be inserted into the lateral locking holeto secure this viewing position. The jigsaw puzzle tablecan be in one of the following four common states relative to its playing space or usage:

1 40 1 11 11 1000 30 1 40 20 30 20 314 11 11 16 17 11 50 1000 35 38 FIGS.- In addition to the four common states mentioned above, the puzzle boardcan achieve any orientation adjustment relative to the user due to the flexible rotation of the rotating assembly. As shown in, the puzzle boardis in the horizontal state, and both the longer edgeA and the shorter edgeB can be positioned at a non-direct front position relative to the user. The jigsaw puzzle tablecan flexibly change its height relative to the user by adjusting the height of the supporting assembly. The puzzle boardcan rotate flexibly relative to the user with the help of the rotating assembly, supported by the supporting portionand the supporting assembly. Through the collaborative action of the supporting portionand the connecting shaft, the puzzle platecan be set to either the inclined or horizontal state. Additionally, when the puzzle plateis in longitudinal state or lateral state, the effective cooperation between the rotating locking portionand the rotating locking partensures that this viewing state is securely locked. At the same time, the tilt angle of the puzzle platecan also be precisely adjusted using the adjusting structure. The jigsaw puzzle tableprovides significant enhancements to the user experience.

57 65 FIGS.to 1000 1000 10 20 10 30 10 20 50 20 30 As shown in, schematic views of the jigsaw puzzle table′ from a second embodiment of the present invention are presented. The jigsaw puzzle table′ comprises a board assembly′, a supporting portion′ located below the board assembly′, a supporting assembly′ supporting the board assembly′ and the supporting portion′, and an adjusting structure′ for adjusting a positional relationship between the supporting portion′ and the supporting assembly′.

10 1 40 1 40 1 1 1 11 12 11 11 12 20 20 40 11 The board assembly′ comprises a puzzle board′ and a rotating assembly′ attached to the puzzle board′. The rotating assembly′ serves as a pivot point for the puzzle board′, allowing the puzzle board′ to rotate in any direction, thereby changing its orientation relative to the user. The puzzle board′ comprises a puzzle plate′ and a fixing frame′ used to support the puzzle plate′. The puzzle plate′ is fixed by the fixing frame′ at a distance from the supporting portion′. In other words, both the supporting portion′ and the rotating assembly′ are located on a back side of the puzzle plate′.

12 121 122 121 123 122 121 11 122 123 121 121 121 121 1210 11 110 The fixing frame′ comprises a fixing portion′, a hollow space′ enclosed by the fixing portion′, and a reinforcing portion′ located within the hollow space′ and connected to the fixing portion′. The puzzle plate′ is housed within the hollow space′ and supported on the reinforcing portion′. The fixing portion′ comprises two longer sidewallsA′ aligned along a longitudinal direction X′ and two shorter sidewallsB′ aligned along a lateral direction Y′. The fixing portion′ has an integral structure, meaning that, unlike in the first embodiment, it is no longer composed of multiple fixing unitsspliced together. Correspondingly, the puzzle plate′ also has an integral structure, no longer made up of multiple plate unitsspliced together.

123 1231 1233 1234 1232 1231 1234 1231 1234 1235 1233 1235 1234 1235 1231 1233 121 1232 171 123 1235 171 1235 1233 40 The reinforcing portion′ comprises a first reinforcing arm′, a pair of third reinforcing arms′, and a pair of fourth reinforcing arms′. In this embodiment, the second reinforcing armfrom the first embodiment is omitted, and the first reinforcing arm′ is divided by the fourth reinforcing arms′, meaning that the first reinforcing arm′ is not positioned between the pair of fourth reinforcing arms′. Additionally, a pair of fifth reinforcing portions′ is added, which are parallel to the third reinforcing arm′. Both ends of the fifth reinforcing portions′ are fixed to the pair of fourth reinforcing arms′, and the pair of fifth reinforcing portions′ are symmetrically distributed on both sides of the first reinforcing arm′, located on a side of the third reinforcing arm′ that is closer to the longer sidewallA′. Due to the omission of the structural second reinforcing arm, there is no suitable location for placing a horizontal locking hole′ in the longitudinal direction within the reinforcing portion′. Therefore, the fifth reinforcing portions′ are additionally included as positioning locations for the horizontal locking hole′, with the fifth reinforcing portions′ located on the outside of the third reinforcing arm′ to avoid interference with the rotating assembly′.

30 311 312 313 314 314 312 The supporting assembly′ comprises a closed frame formed by sequentially connecting a first supporting member′, a second supporting member′, a third supporting member′, and a connecting shaft′. The connecting shaft′ is located opposite to the second supporting member′ and is arranged parallel to it.

20 21 30 22 21 22 312 30 20 30 20 22 312 30 11 20 22 30 20 10 30 11 10 21 20 314 314 The supporting portion′ comprises a connecting portion′ connected to the supporting assembly′ and an extending portion′ extending from the connecting portion′. The extending portion′ is detachably supported on the second supporting member′ of the supporting assembly′. The supporting portion′ can be in either an open state or a closed state relative to the supporting assembly′. When the supporting portion′ is in the closed state, the extending portion′ contacts the second supporting member′ of the supporting assembly′, and the puzzle plate′ is placed horizontally. When the supporting portion′ is in the open state, the extending portion′ is separated from the supporting assembly′, allowing the supporting portion′ to tilt the board assembly′ relative to the supporting assembly′. At this point, the puzzle plate′ of the board assembly′ is also tilted relative to the user. The connecting portion′ of the supporting portion′ is movably connected to the connecting shaft′ and can rotate freely around the connecting shaft′.

1000 24 21 314 24 240 314 241 2410 240 242 241 The jigsaw puzzle table′ further comprises a positioning portion′ limiting a distance between the two connecting portions′ and arranged on the connecting shaft′. The positioning portion′ comprises a positioning part′ fixed to the connecting shaft′, a positioning sleeve′ with a positioning opening′ that fits over the positioning part′, and a positioning pin′ fixed to the positioning sleeve′.

240 21 241 240 2410 242 241 240 314 314 240 242 241 240 314 241 2410 314 3140 241 240 242 3140 240 241 314 The positioning part′ is located between the two connecting portions′, and the positioning sleeve′ is detachably fitted over the positioning part′ through the positioning opening′. The positioning pin′ is used to secure the positioning sleeve′, the positioning part′, and the connecting shaft′ in an axial direction of the connecting shaft′, thereby restricting the axial movement of the positioning part′. The positioning pin′ is inserted into the positioning sleeve′, the positioning part′, and the connecting shaft′, securing it against an outer wall of the positioning sleeve′ and aligned opposite the positioning opening′. The connecting shaft′ is provided with an insertion hole′; after the positioning sleeve′ is fitted over the positioning part′, the positioning pin′ is correspondingly inserted into the insertion hole′, achieving axial fixation of the positioning part′, the positioning sleeve′, and the connecting shaft′.

312 3120 20 20 20 3120 10 20 22 21 The second supporting member′ comprises a receiving portion′ for receiving a free end of the supporting portion′. When the supporting portion′ is in the closed state, the free end of the supporting portion′ is received in the receiving portion′, maintaining a horizontal state of the board assembly′. It should be noted that the free end of the supporting portion′ refers to the end of the extending portion′ that is farthest from the connecting portion′.

24 25 240 21 25 240 21 21 24 21 24 21 25 21 25 25 24 On the other hand, in this embodiment, the positioning portion′ further comprises a contacting portion′ located between the positioning part′ and the connecting portion′. The contacting portion′ simultaneously abuts both the positioning part′ and the connecting portion′, and it is made of a flexible material, such as plastic, rubber or similar material. To ensure both the strength of the connecting portion′ and the positioning portion′, they are typically made of metal. Since the connecting portion′ needs to come into contact with the positioning portion′, friction will occur when the connecting portion′ rotates, generating a harsh noise. However, because the contacting portion′ is made of a flexible material, it will not produce harsh noise when it rubs against the metal connecting portion′. Additionally, compared to metal materials, the thickness of the contacting portion′ can be increased under the same weight conditions to enhance the contact area between the contacting portion′ and the positioning portion′, ensuring the stability of their contact.

40 20 1 41 20 42 41 1 1 1 1 41 42 The rotating assembly′ is sandwiched between the supporting portion′ and the puzzle board′. It comprises a first moving member′ mounted on the supporting portion′ and a second moving member′ rotatably coupled with the first moving member′ and mounted on the puzzle board′. When it is necessary to adjust the orientation of the puzzle board′, a driving force is applied to the puzzle board′, allowing the puzzle board′ to rotate relative to the first moving member′ under the drive of the second moving member′.
