Description

Puzzle Platform Technical Field

[0001] The present invention relates to an educational game device, in particular to a puzzle platform on which a player can piece together multiple puzzle pieces to form a finished puzzle. Background Art

[0002] Research has shown that playing jigsaw puzzles can improve cognitive abilities and visual-spatial reasoning, as well as train players' attention span and patience. Generally speaking, the more pieces a puzzle has, the more difficult it is to complete. Therefore, in addition to being a means of entertainment and enjoyment, players can challenge themselves by playing jigsaw puzzles with larger pieces. However, the larger the number of pieces, the larger the size of the finished puzzle (for example, a rectangular puzzle with 1,000 pieces measures approximately 30"x24", a 5,000-piece puzzle measures approximately 60"x40", and so on). In other words, puzzles with larger pieces require a relatively large playing surface (such as a table or puzzle board) to fit all the pieces together. A skilled puzzle player's strategy for playing jigsaw puzzles typically involves grouping the pieces and pre-assembling the boundaries. However, when the size of the game surface is so large that the player's arms cannot reach from one side of the game surface to the other, the player is required to move around the game surface in order to place puzzle pieces in different directions and sections near each side of the game surface. Summary of the Invention

[0003] The present invention aims to solve the problem that the existing game plane requires players to move around the game plane so as to place puzzle pieces in different directions and parts near each side of the game plane, and provides a puzzle platform.

[0004] To achieve the above-mentioned object, the present invention provides a puzzle platform for being placed on a game table, which includes a puzzle board.

[0005] The puzzle platform further includes: a bracket for supporting the puzzle board and a rotating device connected to the puzzle board and spaced apart from the bracket; the puzzle board includes a carrying plate and a drawer located under the carrying plate; when the bracket supports the puzzle board, the carrying plate, the rotating device and the drawer are respectively tilted relative to the game table; when the bracket does not support the puzzle board, the puzzle board can be rotated on the game table by the rotating device.

[0006] As an improvement, the bracket and the rotating device are spaced apart in the thickness direction of the supporting plate, the plane where the supporting plate is located is set as the projection plane, and the projection of the bracket on the projection plane and the projection of the rotating device on the projection plane at least partially overlap.

[0007] As an improvement, the plane where the supporting plate is located is set as a projection plane, and the projection of the bracket on the projection plane and the projection of the rotating device on the projection plane do not overlap.

[0008] As an improvement, the projection of the bracket on the projection plane falls within the range of the projection of the rotating device on the projection plane.

[0009] As an improvement, the bracket is rotatably connected to the puzzle board, and the bracket can rotate around a rotation axis between a folded position and an unfolded position. The bracket has a rotating end that rotates around the rotation axis and a free end away from the rotating end. When the bracket is in the unfolded position, the free end of the bracket is supported on the game table.

[0010] As an improvement, the rotating device has a proximal end close to the rotation axis, and the proximal end of the rotating device is closer to the rotation axis than the free end of the bracket.

[0011] As an improvement, the rotating device has a proximal end close to the rotation axis, and the proximal end of the rotating device is further away from the rotation axis than the free end of the bracket.

[0012] As an improvement, the rotating device further has a distal end away from the rotation axis, and the free end is closer to the rotation axis than the distal end.

[0013] As an improvement, the puzzle platform further comprises a connecting frame provided on the carrying plate, and the rotating device is connected to a side of the connecting frame facing away from the carrying plate.

[0014] As an improvement, the connecting frame is provided with an avoidance groove for accommodating the bracket.

[0015] The present invention has the following beneficial effects: when the bracket supports the puzzle board, the support plate, rotating device, and drawer are each tilted relative to the game surface; when the bracket does not support the puzzle board, the puzzle board can be rotated on the game surface via the rotating device. The puzzle board can be rotated by the rotating device using an external force, or / and tilted by the bracket supporting the puzzle board, thereby enabling players to place puzzle pieces in different directions and on different parts of the puzzle board without having to move the puzzle board. By rationally arranging the positional relationship between the bracket and the rotating device, the overall structure of the puzzle platform is rational and compact.

[0058] FIG. 43 is a partially exploded view of the puzzle platform shown in FIG. 41 . DETAILED DESCRIPTION

[0059] The present invention will be described in detail below with reference to FIG. 1 to FIG. 43 .

[0060] Referring to Figures 1 to 9 , a puzzle platform 10 according to a first embodiment of the present invention is placed on a gaming surface 20 during use. The puzzle platform 10 includes a puzzle board 1, a bracket 3, and a rotating device 5. The puzzle board 1 has a first side 101 and a second side 103 disposed opposite each other. The puzzle board 1 includes a carrier plate 11, a drawer 17 positioned below the carrier plate 11, and a support frame 12 supporting the carrier plate 11. The support frame 12 includes a frame 13 supporting the carrier plate 11.

[0061] In this embodiment, the frame 13 surrounds and is connected to the carrier plate 11. The frame 13 and the carrier plate 11 together form a first cavity 105 opening at the first side 101 and a second cavity 107 opening at the second side 103. In other words, the carrier plate 11 separates the frame 13 into the first cavity 105 and the second cavity 107.

[0062] The area of ​​the carrier plate 11 exposed to the second cavity 107 is covered with a non-slip mat 14. The non-slip mat 14 can be made of velvet. The non-slip mat 14 provides sufficient friction to prevent the puzzle pieces from sliding when the puzzle board 1 is tilted or rotated. Furthermore, the frame 13 protrudes from the plane of the non-slip mat 14, thus preventing the pieces from sliding.

[0063] As shown in FIG8 , the inner circumference of the frame 13 is provided with a mounting groove 130, and the outer periphery of the carrier plate 11 is embedded in the mounting groove 130. Preferably, the frame 13 is formed by splicing a plurality of frame strips 131 so that the outer periphery of the carrier plate 11 can be embedded in the mounting groove 130 of the frame 13.

[0064] It is understandable that, in other embodiments, the frame 13 and the carrying plate 11 may also be configured to only enclose and form the first cavity 105 opening at the first side 101 .

[0065] The support frame 12 further includes a rib group 15 disposed within the first cavity 105. The rib group 15 is connected to the frame 13 and the support plate 11, respectively, thereby providing support for the support plate 11. Optionally, the rib group 15 is connected only to the frame 13, or the rib group 15 is connected only to the support plate 11.

[0066] The reinforcing rib group 15 includes first reinforcing ribs 151 and second reinforcing ribs 153 spaced apart along a first direction X to form a receiving cavity 15A. The first reinforcing ribs 151 extend at both ends along the second direction Y to connect with the frame 13, and the second reinforcing ribs 153 extend at both ends along the first direction X to connect with the frame 13 and the first reinforcing ribs 151. The first direction X is perpendicular to the second direction Y. It is understood that in other embodiments, the reinforcing rib group 15 may include only the first reinforcing ribs 151.

[0067] The supporting plate 11 , the frame 13 and the reinforcing rib group 15 can all be made of plastic, wood or metal, preferably wood.

[0068] As shown in Figures 5 and 6, the puzzle board 1 is an overall rectangular structure, wherein the first direction X is the length direction of the puzzle board 1, and the second direction Y is the width direction of the puzzle board 1. It is understood that in other embodiments, the puzzle board 1 can also be square, circular, etc.

[0069] A drawer 17 is provided between the second reinforcing rib 153 and the frame 13. The drawer 17 can be used to place puzzle pieces, thereby preventing the puzzle pieces from being lost.

[0070] The bracket 3 is rotatably connected to the puzzle board 1, and the bracket 3 can rotate about a rotation axis 2 between a folded position and an unfolded position. The first direction X is parallel to the rotation axis 2. The bracket 3 has a rotating end 31 that rotates about the rotation axis 2 and a free end 33 away from the rotating end 31. When the bracket 3 is in the unfolded position, the bracket 3 supports the puzzle board 1, and the free end 33 of the bracket 3 is supported on the game surface 20. Under the support of the bracket 3, the puzzle board 1 is tilted and supported on the game surface 20. The support plate 11 and drawer 17 of the puzzle board 1 are respectively tilted relative to the game surface 20, and the rotating device 5 is also tilted relative to the game surface 20. One end of the puzzle board 1 along the second direction Y is supported on the game surface 20.

[0071] As shown in Figure 6, for ease of operation, the drawer 17 is extended along the side of the puzzle board 1. When the drawer 17 is extended, its distance from the game surface 20 remains constant. The bracket 3 supports the puzzle board 1 along its thickness. Because the drawer 17 is extended from the side of the puzzle board 1, the tilt of the puzzle board 1 does not affect the extension of the drawer 17. By properly configuring the extension direction of the drawer 17 and the tilt of the puzzle board 1, the convenience of operation is improved. In this embodiment, the drawer 17 extends along the first direction X.

[0072] It should be noted that the folded position of the bracket 3 refers to a position in which the bracket 3 is parallel or substantially parallel to the supporting plate 11 of the puzzle board 1. The unfolded position of the bracket 3 refers to a position in which the free end 33 of the bracket 3 is supported on the game surface 20, and the angle α between the bracket and the game surface 20 is preferably 90°>α>0°.

[0073] As shown in Figure 3, the bracket 3 is rotatably connected to the puzzle board 1 at the first side 101, so that the bracket 3 in the folded position is accommodated within the receiving cavity 150. In this embodiment, the puzzle platform 10 is provided with a rotatable connection structure 6, through which the bracket 3 is rotatably connected to the first reinforcing rib 151 of the puzzle board 1. The rotation axis 2 is the rotation axis of the rotatable connection structure 6. In this embodiment, the rotatable connection structure 6 is freely rotatable, allowing the bracket 6 to rotate freely between the folded position and the unfolded position.

[0074] The puzzle board 1 restrains the bracket 3 in the expanded position and is further provided with a stopper 7 for restraining the bracket 1 in the folded position. Since the rotating connection structure 6 is configured to rotate freely so that the bracket 6 can rotate freely between the folded position and the expanded position, the bracket 3 needs to be restrained from rotating when it is rotated to the folded position so that the bracket 3 can remain stably in the folded position; and the bracket 3 also needs to be restrained from rotating when it is rotated to the expanded position so that the bracket 3 can remain stably in the expanded position.

[0075] In this embodiment, when the bracket 3 rotates to the expanded position, the frame 13 abuts against the bracket 3 to limit the bracket 3 to the expanded position; the blocking member 7 is rotatably connected to the side of the first reinforcement rib 151 away from the supporting plate 11 so that the blocking member 7 can rotate between the blocking position and the open position.

[0076] When the bracket 3 rotates to the folded position, the blocking member 7 rotates to the blocking position so that the bracket 3 is restricted in the folded position by the blocking member 7; when the blocking member 7 rotates to the open position, the bracket 3 can rotate between the folded position and the unfolded position.

[0077] It should be noted that the blocking member 7 being in the blocking position means that the blocking member 7 is rotated to block the rotation path of the bracket 3; and the blocking member 7 being in the open position means that the blocking member 7 is rotated to a position that does not block the rotation of the bracket 3.

[0078] In this embodiment, the rotating connection structure 6 includes an axial hole 61 and a rotating shaft 63 inserted into the axial hole 61. One of the axial hole 61 and the rotating shaft 63 is disposed on the bracket 3, and the other is disposed on the first reinforcing rib 151 of the puzzle board 1. The axis of the rotating shaft 63 serves as the rotation axis of the rotating connection structure 6. It will be appreciated that in other embodiments, the rotating connection structure 6 may also employ other freely rotatable rotating connection structures 6.

[0079] As shown in Figure 5, the bracket 3 includes a pair of extension rods 35 and a connecting rod 37 spaced apart along a first direction X. The extension rods 35 extend along a second direction Y, and both ends of the connecting rod 37 extend along the first direction X to connect with the extension rods 35. The extension rods 35 are pivotally connected to the first reinforcing rib 151 via a pivoting connection structure 6. The pivoting end 31 is the end connecting the extension rod 35 to the pivoting connection structure 6, and the free end 33 is the end of the extension rod 35 away from the pivoting connection structure 6. It is understood that in other embodiments, the bracket may not include a connecting rod. Accordingly, when the bracket does not include a connecting rod, only one extension rod may be provided; alternatively, multiple connecting rods 37 may be provided.

[0080] Among them, when the bracket 3 is in the expanded position, the extension rod 35 abuts against the frame 13, thereby blocking the bracket 3 from continuing to rotate in the direction away from the folded position through the frame 13, thereby achieving the purpose of the puzzle board 1 limiting the bracket 3 to the expanded position; when the bracket 3 is in the folded position, the extension rod 35 is confined between the blocking member 7 and the supporting plate 11, thereby achieving the purpose of the blocking member 7 limiting the bracket 3 to the folded position.

[0081] The extension rod 35 and the connecting rod 37 are in a cubic shape. In this embodiment, the rotating shaft 63 is provided on the extension rod 35, and accordingly, the shaft hole 61 can be provided on the first reinforcing rib 151. It is understood that in other embodiments, the shaft hole can also be provided on the extension rod, and accordingly, the rotating shaft can be provided on the first reinforcing rib.

[0082] The rotating device 5 is connected to the puzzle board 1 at the first side 101 and spaced apart from the support 3. The plane on which the support plate 11 lies is a projection plane, and the projection of the support 3 on the projection plane does not overlap with the projection of the rotating device 5 on the projection plane. When the support 3 is in the folded position, the support 3 does not support the puzzle board 1, and the puzzle board 1 can be rotated on the playing surface 20 via the rotating device 5. The rotation angle of the puzzle board 1 is preferably set to 360°.

[0083] Specifically, the rotating device 5 has a support surface 51 on the side facing away from the puzzle board 1 that protrudes from the puzzle board 1. When the bracket 3 is in the folded position, the bracket 3 and the rotating device 5 are located on the same side of the support plate 11, with the bracket 3 closer to the support plate 11 than the support surface 51. This allows the puzzle board 1 to rotate under the influence of the rotating device 5 when the support surface 51 is supported by the playing surface 20. In other words, when the bracket 3 is in the folded position, the puzzle board 1 and the bracket 3 do not contact the playing surface 20, allowing the puzzle board 1 to rotate under the influence of the rotating device 5 by external forces.

[0084] It should be noted that when the puzzle board 1 is tilted and supported on the game surface 20 by the support 3 , the rotating device 5 is spaced apart from or in contact with the game surface 20 .

[0085] The rotating device 5 has a proximal end 53 proximal to the rotation axis 2 and a distal end 55 distal to the rotation axis 2. As shown in FIG5 , the rotating device 5 is generally circular, with the proximal end 53 and the distal end 55 located at opposite ends of a diameter of the circle. It will be appreciated that in other embodiments, the rotating device 5 may also be rectangular.

[0086] In this embodiment, the proximal end 53 is closer to the rotation axis 2 than the free end 33, and the free end 33 is closer to the rotation axis 2 than the distal end 55, so that the puzzle board 1 supported by the bracket 3 has a larger design inclination angle, and the positional relationship between the bracket 3 and the rotating device 5 is reasonably arranged, so that the overall structure of the puzzle platform is reasonable and compact.

[0087] As shown in Figures 3, 4, and 9, the center of gravity of the puzzle board 1 is located between the rotation axis 2 and the point where the puzzle board 1 contacts the playing surface 20. This ensures the stability of the puzzle board 1 when supported by the bracket 3. The center of gravity of the puzzle board 1 is located on the rotation axis 109 of the puzzle board 1. This prevents the puzzle board 1 from deflecting due to centrifugal force during rotation.

[0088] In this embodiment, the rotating device 5 is connected to the supporting plate 11 via a connecting frame 8 disposed within the receiving cavity 15A, such that the supporting surface 51 of the rotating device 5 protrudes from the puzzle board 1. Specifically, the connecting frame 8 is fixed to the supporting plate 11, and the rotating device 5 is connected to the side of the connecting frame 8 facing away from the supporting plate 11.

[0089] The connecting frame 8 includes a first frame 81 arranged along a first direction X and a second frame 83 arranged to intersect with the first frame 81 along a second direction Y. The first frame 81 extends at both ends along the first direction X to connect with the first reinforcing rib 151 to strengthen the strength of the puzzle board 1. When the bracket 3 is in the folded position, the extension rod 35 is spaced apart from the first frame 81. It is understood that in other embodiments, the first frame may also be spaced apart from the first reinforcing rib at both ends along the first direction.

[0090] It is understandable that, in other embodiments, the rotating connection structure 6 may also be configured as a hinge, and accordingly, the bracket may be connected to the supporting plate 11 via the rotating connection structure. Example

[0091] Referring to Figures 10 and 11 , the only difference between Example 2 and Example 1 is that the rotating connection structure 6A has a preset locking force, allowing the bracket 3A to be locked in both the folded and unfolded positions. Therefore, there is no need for the puzzle pieces to restrain the bracket in the unfolded position, nor is there a need for a stopper on the puzzle pieces. It is understood that in other embodiments, the frame 13A and the carrier plate 11A can be configured to enclose only the first cavity opening on the first side.

[0092] The process of rotating the connecting structure 6A to lock the bracket 3A in the folded position and the unfolded position is as follows:

[0093] When the user needs to rotate the bracket 3A, an external force is applied to the bracket 3A so that the force acts on the rotating connection structure 6A. When the torque of the force is greater than the torque of the preset locking force, the bracket 3A rotates under the drive of the force, so that the bracket 3A can rotate between the folded position and the unfolded position.

[0094] When the external force is removed or the torque of the external force is less than the torque of the preset locking force, the rotating connection structure 6A cannot rotate because it is in a self-locking state, so that the bracket 3A rotated to the folded position can be locked in the folded position and the bracket 3A rotated to the unfolded position can be locked in the folded position.

[0095] In this embodiment, the rotation connection structure 6A may be a self-locking hinge, wherein the rotation axis 2A is the axis of the rotation shaft of the self-locking hinge.

[0096] Specifically, the frame 13A is connected to the rotation connection structure 6A on the surface of the first side 101A, and the extension rod 35A of the bracket 3A is connected to the rotation connection structure 6A on the side facing away from the supporting plate 11A.

[0097] It is understandable that in other embodiments, the bracket may also be configured to be rotatably connected to the supporting plate 11A of the puzzle board 1A via the rotatable connection structure 6A. Example

[0098] Please refer to FIG. 12 to FIG. 15 , the difference between the third embodiment and the first embodiment is only that:

[0099] The distal end 55B is closer to the rotation axis 2B than the free end 33B, so that the rotating device 5B is surrounded by the bracket 3B.

[0100] The support plate 11B is fixed with a blocking rib 18B spaced apart from the frame 13B, and when the bracket 3B is in the expanded position, the extension rod 35B of the bracket 3B abuts against the blocking rib 18B, thereby allowing the puzzle board 1B to restrict the bracket 3B in the expanded position.

[0101] In this embodiment, both ends of the blocking rib 18B extend along the first direction X to connect with the first reinforcing rib 151B, thereby strengthening the puzzle board 1B. Both ends of the first bracket 81B along the first direction X are spaced from the first reinforcing rib 151B to form a clearance groove 80 for the extension rod 35B. The bracket 3B does not include a connecting rod. Example

[0102] Please refer to FIG16 . The only difference between the fourth embodiment and the third embodiment is that:

[0103] The bracket 3C further includes a connecting rod 37C. Both ends of the connecting rod 37C extend along the first direction X to connect with the extension rod 35C. The rotating device 5C is located in the area enclosed by the extension rod 35C, the connecting rod 37C and the blocking rib 18C. Example

[0104] Please refer to FIG. 17 and FIG. 20 . The difference between the fifth embodiment and the fourth embodiment is only that:

[0105] The extension rod 35D and connecting rod 37D of the bracket 3D are both made of metal wire. The rotating shaft 63D extends from the end of the extension rod 35D away from the connecting rod 37D, with the two rotating shafts 63D disposed opposite each other. In other words, the bracket 3D and rotating shaft 63D are integrally formed. Accordingly, the extension rod 35D, connecting rod 37D, and rotating shaft 63D can be formed by bending metal wire. Iron wire can be used as the metal wire.

[0106] Among them, the rotating end 31D is the connecting end of the extension rod 35D and the rotating shaft 63D, and the connecting rod 37D serves as the free end 33D; during installation, the pair of extension rods 35D are moved toward each other by external force to generate elastic deformation so that the rotating shaft 63D can be inserted into the shaft hole 61D.

[0107] The first frame 81D extends along the first direction X at both ends to connect with the first reinforcing rib 151D, thereby reinforcing the strength of the puzzle board 1D. Furthermore, the first frame 81D is provided with a clearance slot 80D for accommodating the extension rod 35D. It is understood that in other embodiments, the first frame may also extend along the first direction at both ends to form clearance slots for accommodating the extension rod, separated from the first reinforcing rib. Example

[0108] Please refer to FIG. 21 to FIG. 23 , the difference between the sixth embodiment and the fifth embodiment is only that:

[0109] The supporting plate 11E is further fixed with a fixing block 19, and the bracket 3E is rotatably connected to the fixing block 19 via the rotatable connection structure 6E. In other words, the supporting plate 11E is indirectly connected to the rotatable connection structure 6E via the fixing block 19.

[0110] Specifically, the shaft holes 61E of the rotating connection structure 6E are arranged at both ends of the fixed block 19 along the first direction X; the two rotating shafts 63E of the rotating connection structure 6E are arranged facing each other, and during installation, an external force is used to cause a pair of extension rods 35E to move away from each other and generate elastic deformation so that the rotating shafts 63E can be inserted into the shaft holes 61E. Example

[0111] Please refer to FIG. 24 and FIG. 25 . The only difference between the seventh embodiment and the second embodiment is that:

[0112] The bracket 3F includes only one extension rod 35F, and the extension rod 35F is connected to the frame 13F of the puzzle board 1F via a rotating connection structure 6F.

[0113] In this embodiment, the free end 33F of the bracket 3F is closer to the rotation axis 2F than the proximal end 53F of the rotating device 5F, and the puzzle piece 1F is symmetrical with respect to the bracket 3F. The rotating device 5F is connected to the puzzle piece 1F and spaced apart from the bracket 3F.

Example

[0114] Please refer to FIG. 26 to FIG. 28 , the difference between the eighth embodiment and the first embodiment is only that:

[0115] The extension rod 35G and connecting rod 37G of the bracket 3G are both made of metal wire. The rotating shaft 63G extends from the end of the extension rod 35G away from the connecting rod 37G, with the two rotating shafts 63G disposed opposite each other. In other words, the bracket 3G and rotating shaft 63G are integrally formed. Accordingly, the extension rod 35G, connecting rod 37G, and rotating shaft 63G can be formed by bending metal wire. Iron wire can be used as the metal wire.

[0116] Among them, the rotating end 31G is the connecting end of the extension rod 35G and the rotating shaft 63G, and the connecting rod 37G serves as the free end 33G; during installation, the pair of extension rods 35G are moved toward each other by external force to generate elastic deformation so that the rotating shaft 63G can be inserted into the shaft hole 61G.

[0117] In this embodiment, the free end 33G of the bracket 3G is closer to the rotation axis 2G than the proximal end 53G of the rotating device 5G. The rotating device 5G is connected to the puzzle board 1G and spaced apart from the bracket 3G. The plane on which the carrier plate 11G lies is defined as a projection plane, and the projection of the bracket 3G on the projection plane does not overlap with the projection of the rotating device 5G on the projection plane. Example

[0118] Please refer to FIG. 29 and FIG. 30 . The difference between the ninth embodiment and the second embodiment is only that:

[0119] The bracket 3H is located in the hollow area of ​​the rotating device 5H. The rotating device 5H is connected to the supporting plate 11H via the reinforcing rib group 15H so that the supporting surface 51H of the rotating device 5H protrudes from the puzzle board 1H, thus, no connecting frame is required.

[0120] As shown in Figure 30, the rib assembly 15H also includes a pair of third ribs 155H spaced apart along the second direction Y. Both ends of the third ribs 155H along the first direction X extend to connect with the first rib 151H. At least one of the first rib 151H, the second rib 153H, and the third rib 155H is connected to the rotating device 5H. The bracket 3H includes only one extension rod 35H, which is connected to the third rib 155H via a rotating connection structure 6H.

[0121] In this embodiment, puzzle board 1H is symmetrical about bracket 3H. Rotating device 5H is connected to puzzle board 1H and spaced apart from bracket 3H. The plane on which carrier plate 11H lies is defined as a projection plane. The projection of bracket 3H on the projection plane does not overlap with the projection of rotating device 5H on the projection plane. The projection of bracket 3H on the projection plane falls within the range of the projection of rotating device 5H on the projection plane. Example

[0122] Please refer to FIG. 31 to FIG. 33 , the difference between the tenth embodiment and the first embodiment is only that:

[0123] The bracket 3H is located in the hollow area of ​​the rotating device 5H.

[0124] The rotating device 5I is connected to the supporting plate 11I via the reinforcing rib group 15I so that the supporting surface 51I of the rotating device 5I protrudes from the puzzle board 1I. Therefore, there is no need to set up a connecting frame.

[0125] As shown in Figure 33, the reinforcing rib group 15I also includes a pair of third reinforcing ribs 155I arranged at intervals along the second direction Y. Both ends of the third reinforcing rib 155I along the first direction X extend to connect with the first reinforcing rib 151I, and at least one of the first reinforcing rib 151I, the second reinforcing rib 153I and the third reinforcing rib 155I is connected to the rotating device 5I.

[0126] Among them, when the bracket 3I rotates to the unfolded position, the extension rod 35I of the bracket 3I abuts against the third reinforcing rib 155I, thereby blocking the bracket 3I from continuing to rotate in the direction away from the folded position through the third reinforcing rib 155I, thereby achieving the purpose of the puzzle board 1I limiting the bracket 3I to the unfolded position.

[0127] In this embodiment, the rotating device 5I is connected to the puzzle board 1I and spaced apart from the bracket 3I. The plane on which the carrier plate 11I lies is defined as a projection plane. The projection of the bracket 3I on the projection plane does not overlap with the projection of the rotating device 5I on the projection plane. The projection of the bracket 3I on the projection plane falls within the range of the projection of the rotating device 5I on the projection plane. Example

[0128] Please refer to FIG34 . The only difference between the eleventh embodiment and the fifth embodiment is that:

[0129] The blocking ribs 18J and the bracket 3J are located in the hollow area of ​​the rotating device 5J. The rotating device 5J is connected to the supporting plate 11J via the reinforcing rib group 15J so that the supporting surface 51J of the rotating device 5J protrudes from the puzzle board 1J, thus, no connecting frame is required.

[0130] The reinforcing rib group 15H also includes a pair of third reinforcing ribs 155J spaced apart along the second direction Y. Both ends of the third reinforcing ribs 155J along the first direction X extend to connect with the first reinforcing rib 151J. At least one of the first reinforcing rib 151J, the second reinforcing rib 153J and the third reinforcing rib 155J is connected to the rotating device 5J.

[0131] In this embodiment, the rotating device 5J is connected to the puzzle board 1J and spaced apart from the bracket 3J. The plane on which the carrier plate 11J lies is defined as a projection plane. The projection of the bracket 3J on the projection plane does not overlap with the projection of the rotating device 5J on the projection plane. The projection of the bracket 3J on the projection plane falls within the range of the projection of the rotating device 5J on the projection plane. Example

[0132] Please refer to FIG35 . The difference between the twelfth embodiment and the sixth embodiment is only that:

[0133] The fixing block 19K and the bracket 3K are located in the hollow area of ​​the rotating device 5K. The rotating device 5K is connected to the supporting plate 11K via the reinforcing rib group 15K so that the supporting surface 51K of the rotating device 5K protrudes from the puzzle board 1K, thus eliminating the need for a connecting frame.

[0134] The reinforcing rib group 15K also includes a pair of third reinforcing ribs 155K spaced apart along the second direction Y. Both ends of the third reinforcing ribs 155K along the first direction X extend to connect with the first reinforcing rib 151K. At least one of the first reinforcing rib 151K, the second reinforcing rib 153K and the third reinforcing rib 155K is connected to the rotating device 5K.

[0135] When the bracket 3K rotates to the unfolded position, it abuts against the third reinforcing rib 155K, thereby preventing the bracket 3K from further rotating away from the folded position. This allows the puzzle board 1K to restrict the bracket 3K in the unfolded position. Therefore, there is no need for a blocking rib.

[0136] In this embodiment, the rotating device 5J is connected to the puzzle board 1J and spaced apart from the bracket 3J. The plane on which the carrier plate 11J lies is defined as a projection plane. The projection of the bracket 3J on the projection plane does not overlap with the projection of the rotating device 5J on the projection plane. The projection of the bracket 3J on the projection plane falls within the range of the projection of the rotating device 5J on the projection plane. Example

[0137] 36 and 37 , the only difference between the thirteenth embodiment and the seventh embodiment is that the puzzle board 1L further includes a bottom plate 10 , which is fixed to the side of the support frame 12L facing away from the carrier plate 11L. The bottom plate 10 can further strengthen the puzzle board 1L.

[0138] The rotating device 5L is fixed to a side of the bottom plate 10 facing away from the supporting frame 12L so that the supporting surface 51L of the rotating device 5L protrudes from the puzzle board 1L.

[0139] A window 100 is provided on the bottom plate 10 to expose the bracket 3L and the rotating connection structure 6L, and the window 100 is configured so that the bracket 3L can freely pass through the window 100 during the rotation process.

[0140] In this embodiment, the rotating device 5L is connected to the puzzle board 1L and spaced apart from the bracket 3L. The plane on which the carrier plate 11L lies is defined as a projection plane, and the projection of the bracket 3L on the projection plane does not overlap with the projection of the rotating device 5L on the projection plane. The projection of the bracket 3L on the projection plane falls within the projection of the rotating device 5L on the projection plane. Example

[0141] Please refer to FIG. 38 to FIG. 40 , the difference between the fourteenth embodiment and the ninth embodiment is only that:

[0142] The bracket 3M includes only a pair of extension rods 35M spaced apart along a first direction X. The extension rods 35M extend along the first direction X and are spaced apart from the rotating device 5M along a second direction Y. The extension rods 35M are connected to the frame 13M via a rotating connection structure 6M.

[0143] As shown in Figure 40, the rotating connection structure 6M includes an axial hole 61M and a rotating shaft 63M inserted into the axial hole 61M, wherein the axial hole 61M is provided on the extension rod 35M and the frame 13M, the rotating shaft 63M is a bolt, and the other end of the rotating shaft 63M passes through a nut 65 to limit its displacement along the second direction Y.

[0144] As shown in FIG39 , when the bracket 3M rotates to the unfolded position, the bracket 3M abuts against the first reinforcing rib 151M, thereby preventing the bracket 3M from further rotating in the direction away from the folded position through the first reinforcing rib 151M.

[0145] It is understandable that, in other embodiments, the bracket 3M may also be configured to include only one extension rod 35M, or the bracket 3M may be connected to the first reinforcing rib 151M via a rotating connection structure (e.g., a self-locking hinge) with a preset locking force.

[0146] In this embodiment, the rotating device 5M is connected to the puzzle board 1M and spaced apart from the bracket 3M. The plane where the carrier plate 11M is located is set as a projection plane, and the projection of the bracket 3M on the projection plane does not overlap with the projection of the rotating device 5M on the projection plane. Example

[0147] Referring to Figures 41 to 43 , the fifteenth embodiment differs from the first embodiment in that the bracket 3N and puzzle board 1N are designed as separate components. To use the bracket 3N, the bracket 3N and puzzle board 1N must first be assembled. When the bracket 3N supports the puzzle board 1N, the support plate 11N, rotating device 5N, and drawer 17N are each tilted relative to the game surface.

[0148] When the bracket 3N is no longer supporting the puzzle board 1N, the bracket 3N is removed from the puzzle board 1N, and the puzzle board 1N can be rotated on the game surface via the rotating device 5N. The bracket 3N and the rotating device 5N are spaced apart in the thickness direction of the support plate 11N. The plane on which the support plate 11N lies is a projection plane, and the projection of the bracket 3N on the projection plane and the projection of the rotating device 5N on the projection plane at least partially overlap. By rationally arranging the positional relationship between the bracket 1N and the rotating device 5N, the overall structure of the puzzle platform 10N is rational and compact. The bracket 3N includes a pair of extension rods 35N spaced apart in a first direction X and a connecting rod 37N that simultaneously connects the two extension rods 35N. The extension rods 35N extend in a second direction Y. The connecting rod 37N of the bracket 3N and the rotating device 5N are spaced apart in the thickness direction of the support plate 11N. The projection of the connecting rod 37N of the bracket 3N on the projection plane and the projection of the rotating device 5N on the projection plane at least partially overlap. The extension rod 35N of the bracket 3N and the rotating device 5N are spaced apart along the first direction X. The projection of the extension rod 35N of the bracket 3N on the projection plane does not overlap with the projection of the rotating device 5N on the projection plane.

[0149] In this embodiment, the rotating device 5N can be designed as a whole with the puzzle board 1N. In an optional embodiment, the rotating device 5N and the puzzle board 1N are designed as separate bodies, and when the puzzle board 1N needs to be rotated, the rotating device 5N and the puzzle board 1N are assembled together.

[0150] The above description is only an embodiment of the present invention. It should be pointed out that those skilled in the art can make improvements without departing from the creative concept of the present invention, but these improvements all fall within the scope of protection of the present invention.
