Description

[Technical field]

[0001] The utility model relates to an educational game device, in particular to a puzzle platform on which a player can piece together a plurality of puzzle pictures to form a finished puzzle product. [Background technology]

[0002] Research shows that playing jigsaw puzzles can improve players' cognitive abilities and visual-spatial reasoning abilities, as well as train players' attention and patience. Generally speaking, the more pieces a jigsaw puzzle has, the more difficult it is to put together the jigsaw puzzle. Therefore, in addition to being a means of entertainment and enjoyment, players can also challenge themselves by playing jigsaw puzzles with more pieces. However, the more pieces a jigsaw puzzle has, the larger the size of the jigsaw puzzle (e.g., a rectangular jigsaw puzzle with 1,000 pieces is about 30"x24", a 5,000-piece jigsaw puzzle is about 60"x40", and so on). In other words, a jigsaw puzzle with more pieces requires a relatively large playing surface (such as the surface of a table or puzzle board) in order to put all the pieces together to form the jigsaw puzzle. As a skilled player, the strategy for playing jigsaw puzzles is usually to group the pieces and pre-assemble 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 to place puzzle pieces in different directions and portions near each side of the game surface. [Contents of the utility model]

[0003] The utility model provides a puzzle platform 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.

[0004] To achieve the above-mentioned purpose, the utility model provides a puzzle platform for being placed on a game table, which includes a puzzle board. The puzzle platform also 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 bearing plate and a drawer under the bearing plate; when the bracket supports the puzzle board, the bearing 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 through the rotating device.

[0005] 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 a 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.

[0006] As an improvement, the plane where the carrying 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.

[0007] 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.

[0008] 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.

[0009] As an improvement, the rotating device has a proximal end close to the rotating axis, and the proximal end of the rotating device is closer to the rotating axis than the free end of the bracket.

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

[0011] 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.

[0012] As an improvement, the jigsaw puzzle platform further comprises a connecting frame arranged on the carrying plate, and the rotating device is connected to a side of the connecting frame facing away from the carrying plate.

[0013] As an improvement, the connecting frame is provided with an avoidance groove for accommodating the bracket.

[0014] The beneficial effects of the utility model are as follows: when the bracket supports the puzzle board, the bearing plate, the rotating device and the drawer are respectively arranged to be 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. The puzzle board can be rotated by the rotating device under the action of an external force or / and the puzzle board can be supported by the bracket to be tilted, so that the player can place puzzle pieces in different directions and parts of the puzzle board without moving. By reasonably arranging the positional relationship between the bracket and the rotating device, the overall structure of the puzzle platform is reasonable and compact.

[0058] Combine the following Figures 1 to 43 The utility model is described in detail.

[0059] Please refer to Figures 1 to 9 The puzzle platform 10 of the first embodiment of the present invention is placed on the game table 20 when in 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 arranged opposite to each other. The puzzle board 1 includes a carrier board 11, a drawer 17 located under the carrier board 11 and a support frame 12 supporting the carrier board 11. The support frame 12 includes a frame 13 supporting the carrier board 11.

[0060] In this embodiment, the frame 13 is disposed around the carrier plate 11 and connected to the carrier plate 11, and the frame 13 and the carrier plate 11 together enclose a first cavity 105 opened at the first side 101 and a second cavity 107 opened 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.

[0061] The area of ​​the carrier plate 11 exposed outside the second cavity 107 is covered with an anti-skid pad 14. The anti-skid pad 14 can be made of velvet. The anti-skid pad 14 has a large friction force so that after the puzzle pieces are placed on the anti-skid pad 14, the puzzle pieces will not slide due to the tilting or rotation of the puzzle board 1, and the frame 13 protrudes from the plane where the anti-skid pad 14 is located so that the frame 13 can also limit the sliding of the puzzle pieces.

[0062] like Figure 8 As shown, the inner circumference of the frame 13 is provided with a mounting groove 130, and the outer circumference 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 circumference of the carrier plate 11 is embedded in the mounting groove 130 of the frame 13.

[0063] 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 .

[0064] The support frame 12 further includes a reinforcing rib group 15 disposed in the first cavity 105. The reinforcing rib group 15 is respectively connected to the frame 13 and the load-bearing plate 11, thereby providing support force for the load-bearing plate 11. Optionally, the reinforcing rib group 15 is only connected to the frame 13, or the reinforcing rib group 15 is only connected to the load-bearing plate 11.

[0065] The reinforcing rib group 15 includes a first reinforcing rib 151 and a second reinforcing rib 153 which are spaced along the first direction X to form the storage cavity 15A. The first reinforcing rib 151 extends along both ends of the second direction Y to connect with the frame 13, and the second reinforcing rib 153 extends along both ends of the first direction X to connect with the frame 13 and the first reinforcing rib 151. The first direction X is perpendicular to the second direction Y. It is understandable that in other embodiments, the reinforcing rib group 15 may also include only the first reinforcing rib 151.

[0066] The bearing plate 11 , the frame 13 and the reinforcing rib group 15 can be made of plastic, wood or metal, preferably wood.

[0067] like Figure 5 and Figure 6 As shown, the puzzle board 1 is in a rectangular structure as a whole, 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 may also be square, circular, etc.

[0068] 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.

[0069] The bracket 3 is rotatably connected to the puzzle board 1, and the bracket 3 can rotate around 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 rotating around 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 table 20. Under the support of the bracket 3, the puzzle board 1 is tilted and supported on the game table 20, and the support plate 11 and the drawer 17 of the puzzle board 1 are respectively tilted relative to the game table 20, and the rotating device 5 is also tilted relative to the game table 20. One end of the puzzle board 1 along the second direction Y is supported on the game table 20.

[0070] like Figure 6 As shown, for ease of operation, the drawer 17 is stretched along the side of the puzzle board 1. When the drawer 17 is stretched, the distance between it and the game table 20 remains unchanged. The bracket 3 supports the puzzle board 1 in the thickness direction of the puzzle board 1. Because the drawer 17 is stretched from the side of the puzzle board 1, the inclination of the puzzle board 1 does not affect the stretching operation of the drawer 17. By reasonably setting the stretching direction of the drawer 17 and the inclination mode of the puzzle board 1, the convenience of the player's operation is improved. In this embodiment, the drawer 17 is stretched along the first direction X.

[0071] It should be noted that the folded position of the bracket 3 refers to the position where 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 the position where the free end 33 of the bracket 3 is supported on the game surface 20, and the angle between the game surface 20 and the bracket is α. Preferably, 90°>α>0°.

[0072] like Figure 3As shown, 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 in the accommodation cavity 150. In this embodiment, the puzzle platform 10 is provided with a rotatable connection structure 6, and the bracket 3 is rotatably connected to the first reinforcing rib 151 of the puzzle board 1 via the rotatable connection structure 6. Among them, the rotation axis 2 is the rotation axis of the rotatable connection structure 6. In this embodiment, the rotatable connection structure 6 can rotate freely so that the bracket 6 can rotate freely between the folded position and the unfolded position.

[0073] The puzzle board 1 restricts the bracket 3 to the unfolded position, and a blocking member 7 is also provided on the puzzle board 1 to restrict the bracket 1 to the folded position. Since the rotating connection structure 6 is configured to be freely rotatable so that the bracket 6 can freely rotate between the folded position and the unfolded position, when the bracket 3 rotates to the folded position, it needs to be restricted from rotating so that the bracket 3 can be stably in the folded position; when the bracket 3 rotates to the unfolded position, it also needs to be restricted from rotating so that the bracket 3 can be stably in the unfolded position.

[0074] In this embodiment, when the bracket 3 rotates to the unfolded position, the frame 13 abuts against the bracket 3 to limit the bracket 3 in the unfolded position; the blocking member 7 is rotatably connected to the side of the first reinforcing rib 151 away from the supporting plate 11 so that the blocking member 7 can rotate between the blocking position and the open position.

[0075] 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.

[0076] 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 where it does not block the rotation of the bracket 3 .

[0077] 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 which is arranged on the bracket 3, and the other is arranged on the first reinforcing rib 151 of the puzzle board 1. The axis of the rotating shaft 63 is the rotating axis of the rotating connection structure 6. It can be understood that in other embodiments, the rotating connection structure can also adopt other freely rotatable rotating connection structures 6.

[0078] like Figure 5As shown, the bracket 3 includes a pair of extension rods 35 and a connecting rod 37 spaced apart along a first direction X, the extension rod 35 extends along a second direction Y, and both ends of the connecting rod 37 extend along the first direction X to connect with the extension rod 35. The extension rod 35 is rotatably connected to the first reinforcing rib 151 via a rotating connection structure 6, the rotating end 31 is the connecting end of the extension rod 35 and the rotating connection structure 6, and the free end 33 is the end of the extension rod 35 away from the rotating connection structure 6. It can be understood that in other embodiments, the bracket may not include a connecting rod, and accordingly, when the bracket does not include a connecting rod, only one extension rod may be provided; or, a plurality of connecting rods 37 may be provided.

[0079] Among them, when the bracket 3 is in the unfolded 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 in the unfolded position; when the bracket 3 is in the folded position, the extension rod 35 is restricted between the blocking member 7 and the supporting plate 11, thereby achieving the purpose of the blocking member 7 limiting the bracket 3 in the folded position.

[0080] The extension rod 35 and the connecting rod 37 are in a cubic shape. In this embodiment, the shaft 63 is arranged on the extension rod 35, and accordingly, the shaft hole 61 can be arranged on the first reinforcing rib 151. It can be understood that in other embodiments, the shaft hole can also be arranged on the extension rod, and accordingly, the shaft is arranged on the first reinforcing rib.

[0081] The rotating device 5 is connected to the puzzle board 1 at the first side 101 and is spaced apart from the bracket 3. The plane where the carrying plate 11 is located is set as a projection plane, and the projection of the bracket 3 on the projection plane and the projection of the rotating device 5 on the projection plane do not overlap. When the bracket 3 is in the folded position, the bracket 3 does not support the puzzle board 1, and the puzzle board 1 can be rotated on the game table 20 through the rotating device 5. Among them, the rotation angle of the puzzle board 1 is preferably set to 360°.

[0082] Specifically, the rotating device 5 has a support surface 51 protruding from the puzzle board 1 on the side facing away 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, and the bracket 3 is closer to the support plate 11 of the puzzle board 1 relative to the support surface 51. In this way, when the support surface 51 is supported by the game table 20, the puzzle board 1 can be rotated by the rotating device 5 through an external force. In other words, when the bracket 3 is in the folded position, the puzzle board 1 and the bracket 3 will not contact the game table 20 so that the puzzle board 1 can be rotated by the rotating device 5 through an external force.

[0083] It should be noted that when the puzzle board 1 is tilted and supported on the game surface 20 under the support of the bracket 3 , the rotating device 5 is spaced apart from or in contact with the game surface 20 .

[0084] The rotating device 5 has a proximal end 53 close to the rotation axis 2 and a distal end 55 away from the rotation axis 2. Figure 5 As shown, the rotating device 5 is a circular structure as a whole, and the proximal end 53 and the distal end 55 are located at two ends of the diameter of a circle. It can be understood that in other embodiments, the rotating device 5 can also be rectangular.

[0085] 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.

[0086] like Figure 3 , Figure 4 and Fig. 9 As shown, the center of gravity of the puzzle board 1 is located between the rotation axis 2 and the portion where the puzzle board 1 contacts the game 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.

[0087] In this embodiment, the rotating device 5 is connected to the carrier plate 11 via the connecting frame 8 disposed in the storage cavity 15A so that the supporting surface 51 of the rotating device 5 protrudes from the puzzle board 1. Specifically, the connecting frame 8 is fixed on the carrier plate 11, and the rotating device 5 is connected to the side of the connecting frame 8 away from the carrier plate 11.

[0088] The connecting frame 8 includes a first frame 81 arranged along a first direction X and a second frame 83 arranged to cross the first frame 81 along a second direction Y, wherein both ends of the first frame 81 along the first direction X extend to connect with the first reinforcing rib 151 to strengthen the strength of the puzzle board 1, and when the bracket 3 is in the folded position, the extension rod 35 is spaced from the first frame 81. It can be understood that in other embodiments, both ends of the first frame along the first direction can also be arranged to be spaced from the first reinforcing rib respectively.

[0089] 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.

[0090] Embodiment 2

[0091] See also Fig.10 and Fig.11The difference between the second embodiment and the first embodiment is that the rotating connection structure 6A has a preset locking force so that the bracket 3A can be locked in the folded position and the unfolded position. Therefore, there is no need to limit the bracket in the unfolded position by the puzzle board, and there is no need to set a blocking member on the puzzle board. It can be understood that in other embodiments, the frame 13A and the carrier board 11A can also be configured to only enclose and form a first cavity with an 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 due to being in a self-locking state, thereby enabling the bracket 3A rotated to the folded position to be locked in the folded position and enabling the bracket 3A rotated to the unfolded position to be locked in the folded position.

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

[0096] Specifically, the frame 13A is connected to the rotating connection structure 6A on the surface of the first side 101A, and the extension rod 35A of the bracket 3A is connected to the rotating 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 carrier plate 11A of the puzzle board 1A via the rotatable connection structure 6A.

[0098] Embodiment 3

[0099] Please refer to Figures 12 to 15 The difference between the third embodiment and the first embodiment is that:

[0100] 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.

[0101] The carrier plate 11B is fixed with a blocking rib 18B spaced apart from the frame 13B, and when the bracket 3B is in the unfolded position, the extension rod 35B of the bracket 3B abuts against the blocking rib 18B, so that the puzzle board 1B restricts the bracket 3B in the unfolded position.

[0102] 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 strength of the puzzle board 1B. Both ends of the first frame 81B along the first direction X are spaced from the first reinforcing rib 151B to form an escape groove 80 for escaping the extension rod 35B. The bracket 3B does not include a connecting rod.

[0103] Embodiment 4

[0104] See also Fig.16 The difference between the fourth embodiment and the third embodiment is only that:

[0105] 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.

[0106] Embodiment 5

[0107] Please refer to Fig.17 and Fig. 20 The difference between the fifth embodiment and the fourth embodiment is only that:

[0108] The extension rod 35D and the connecting rod 37D of the bracket 3D are both made of metal wires, and the rotating shaft 63D is formed by extending from one end of the extension rod 35D away from the connecting rod 37D, and the two rotating shafts 63D are arranged opposite to each other. In other words, the bracket 3D and the rotating shaft 63D are integrally formed, and accordingly, the extension rod 35D, the connecting rod 37D and the rotating shaft 63D can be formed by bending metal wires. Among them, the metal wire can be iron wire.

[0109] 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, an external force is used to make a pair of extension rods 35D move toward each other and generate elastic deformation so that the rotating shaft 63D can be inserted into the shaft hole 61D.

[0110] The first frame 81D extends at both ends along the first direction X to connect with the first reinforcing rib 151D, so that the strength of the puzzle board 1D can be strengthened by the first frame 81D. At the same time, the first frame 81D is provided with an escape groove 80D for escaping the extension rod 35D. It can be understood that in other embodiments, the first frame can also be spaced from the first reinforcing rib at both ends along the first direction to form an escape groove for escaping the extension rod.

[0111] Embodiment 6

In other words, the bracket 3G and the rotating shaft 63G are integrally formed, and accordingly, the extension rod 35G, the connecting rod 37G and the rotating shaft 63G can be formed by bending metal wires. Among them, the metal wire can be iron wire.

Therefore, there is no need to set a blocking rib.

[0161] When the bracket 3N does not support 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 table by the rotating device 5N. The bracket 3N and the rotating device 5N are arranged at intervals in the thickness direction of the bearing plate 11N, and the plane where the bearing plate 11N is located is set as 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.

The bracket 3N includes a pair of extension rods 35N arranged at intervals along the first direction X and a connecting rod 37N that simultaneously connects the two extension rods 35N. The extension rod 35N extends along the second direction Y. The connecting rod 37N of the bracket 3N and the rotating device 5N are arranged at intervals in the thickness direction of the bearing 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 arranged at intervals 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.

In an optional embodiment, the rotating device 5N and the puzzle board 1N are designed separately, and when the puzzle board 1N needs to be rotated, the rotating device 5N and the puzzle board 1N are assembled together.

[0163] The above is only an implementation method of the present invention. It should be pointed out that a person skilled in the art can make improvements without departing from the inventive concept of the present invention, but these improvements are all within the protection scope of the present invention.
