Description

BACKGROUND OF THE PRESENT INVENTION

Field of Invention

The present invention relates to puzzle game apparatus, and more particularly to a movable puzzle platform, wherein the puzzle platform is configured for retaining all the unfinished pieces and while allowing the player to conveniently play the puzzle.

Description of Related Arts

Puzzles are devised over the years and are among the most popular board games generally played alone by an individual. It is well known that puzzles are good for the brain. Studies have shown that playing puzzles can improve cognition and visual-spatial reasoning, and can train concentration and patience.

Other than as a means of entertainment and enjoyment, players would like to challenge themselves by playing higher piece counts of the puzzle. Generally speaking, the higher the piece count, the harder the puzzle is. However, a common drawback or a burden for the player is that the finished size of the puzzles is relatively large. For example, a finished size of 1,000 piece puzzles is about 30″×24″, a finished size of 5,000 piece puzzles is about 60″×40″, and so on. In other words, these puzzles require a relatively large playing surface such as the surface of a table or a puzzle board for putting all the pieces together to form a puzzle figure. Therefore, to play a relatively large puzzle, for example 60″×40″ or more, the side length of the puzzle board is longer than the player's arm length that the player is unable to reach the other sides of the puzzle board, so that the player is required to move around the playing surface to put pieces at different directions and portions near each side of the puzzle board. As a skilled player, the strategies for playing the puzzles are configured for sorting the pieces into groups and assembling the border first. Therefore, the player will need to move from one side of the playing surface to another side thereof to play the puzzles. Furthermore, it could take hours, days or even months to compete a larger scale puzzle. One or more puzzle pieces could be missed accidentally or unintentionally. It is sad that the player usually finds out there is a missing piece at the end. Therefore, how to avoid losing any pieces, it is best to find a container to save all the unfinished pieces.

A need exists for a tool that retains all the unfinished pieces and while allowing the player to conveniently play the puzzle. It is to the provision of such a tool that the present disclosure is primarily directed.

SUMMARY OF THE PRESENT INVENTION

The invention is advantageous in that it provides a movable puzzle platform, wherein the puzzle platform is configured for allowing a player to conveniently play the puzzles.

The general principles defined in the following description would be applied to other embodiments, alternatives, modifications, equivalents, and applications without departing from the spirit and scope of the present invention.

Referring to FIGS. 1 to 15, a movable puzzle platform 1 according to a first embodiment of the present invention is illustrated, wherein the movable puzzle platform 1 is arranged for a user or a player to assemble a plurality of puzzle pieces 100 thereon. Accordingly, the movable puzzle platform 1 comprises a board assembly 90 and a rotating assembly 20 attached on the board assembly 90. The board assembly 90 comprises a puzzle board 10 for placing the puzzle pieces 100, a supplement arrangement 30 attached on the puzzle board 10, a base 40 attached on the supplement arrangement 30, and a restricting wall 50 upwardly extended from a peripheral edge of the puzzle board 10. The rotating assembly 20 is configured for allowing the board assembly 90 sliding on a playing place and provides accessibility for the board assembly 90 to move the board assembly 90 at different planar directions with respect to the playing place. The supplement arrangement 30 is configured not only for storing the puzzle pieces 100 before they are assembled, but also for allowing the player to preassemble and store a section of the puzzle figure with a group of puzzle pieces 100. The supplement arrangement 30 and the restricting wall 50 are positioned at the two sides of the puzzle board 10, respectively. Although good results have been shown with the board assembly 90 that is rectangular in shape, it is within the scope of the present invention that numerous other shapes of the board assembly 90 could be used to achieve the desired functionality as described herein. The movable puzzle platform 1 is manufactured from a suitable durable material such as wood combined with durable fiberboard. In another embodiment, a movable puzzle platform could be manufactured from plastic or fiberglass. In yet another embodiment, a puzzle board is made of non-slip felt surfaces to keep the puzzle pieces secure.

The puzzle board 10 with an even thickness may take any shape, such as circular, square, rectangular and so on. According to this embodiment as shown in FIGS. 1-2 and 11, the puzzle board 10 is embodied to have a rectangular shape defining two longer longitudinal sides provided along a longitudinal direction X and two shorter transverse sides provided along a lateral direction Y perpendicular to the longitudinal direction X. Accordingly, the puzzle board defines XY coordinate surface. The puzzle board 10 comprises a puzzle plate 101 for playing the puzzle pieces 100 thereon and a fixing portion 102 extending from the edge of the puzzle plate 101 and connected with the supplement arrangement 30 and the restricting wall 50, respectively. The puzzle plate 101 comprises a flat playing surface 11 and a bottom surface 12 opposite to the playing surface 11. It is worth mentioning that an area of the playing surface 11 is not smaller than an area of the puzzle pieces 100 being put together. Preferably, the area of the playing surface 11 matches with the area of the puzzle pieces 100 after the puzzle pieces 100 are assembled. In other words, the puzzle board 10 serves as a puzzle frame for framing the puzzle pieces 100 after the puzzle pieces 100 are assembled. It is worth mentioning that the puzzle board 10 has a predetermined size adapted for a larger scale puzzle, such as at least 1,000 puzzle pieces, being assembled on the puzzle board 10.

In this embodiment, the restricting wall 50 is substantially perpendicular to the puzzle board 10 and is generally four-piece type. The restricting wall 50 comprises a first extending wall 51 mounted on the fixing portion 102 and arranged in the longitudinal direction X, a second extending wall 52 mounted on the fixing portion 102 and spaced apart from the first extending wall 51, a third extending wall 53 mounted on the fixing portion 102 and arranged in the lateral direction Y for connected with the adjacent first and second extending walls 51, 52, and a fourth extending wall 54 mounted on the fixing portion 102 and spaced apart from the third extending wall 53 for connected with the adjacent first and second extending walls 51, 52. The first and second extending walls 51, 52 are parallel to each other in the longitudinal direction X. The third and fourth extending walls 53, 54 are parallel to each other in the lateral direction Y. The restricting wall 50 is configured for preventing the players from accidentally or unintentionally pushing the puzzle pieces 100 off the puzzle plate 101. Each of extending walls is substantially strip-shaped and connected with the adjacent extending walls for forming the restricting wall 50 having a closed structure. The restricting wall with a closed curve shape is configured for preventing the puzzle pieces fall off from the puzzle board when the board assembly is rotated on the playing place via a rotation movement of the rotating assembly and/or when the board assembly is moved by a user or a player from one place to another. Each of extending walls may be detachably assembled edge-to-edge to form the restricting wall 50. It is optional that a restricting wall may be an integral unit. Optionally, adjacent extending walls are unconnected with each other. A restricting wall further four arc walls located on four corners of a puzzle plate and smoothly connecting two adjacent extending walls. It is optional that each arc wall is configured to be a part of a circle.

The supplement arrangement 30 comprises a supporting portion 301 connected with the bottom surface 12 of the puzzle plate 101 for forming at least one drawer cavity 31 and at least one puzzle drawer 32 received in the corresponding drawer cavity 31. The puzzle board 10 of the movable puzzle platform 1 has a thin and big size. A length and/or a width of the puzzle board 10 is much greater than a thickness of the puzzle board 10, so the supporting portion 301 is configured for improving the structural strength of the puzzle board 10. The supporting portion 301 is substantially perpendicular to the puzzle board 10 and may take any shape, such as circular, square, rectangular and so on. As shown in FIGS. 1-15, in this embodiment, the supplement arrangement 30 has six drawer cavities 31 and six puzzle drawers 32 received in the corresponding drawer cavity 31. The storing capacity of drawers vary as per varying sizes of the puzzle pieces. The drawer cavities 31 comprise four lateral cavities 302 and two longitudinal cavities 303.

The fourth lateral cavity 36 is formed by the first main supporting wall 311 cooperated with the second dividing supporting wall 314 and the second inner supporting wall 316. In this embodiment, the first dividing supporting wall 313 cooperates with the first and second main supporting wall 311,312 for varying volumes of the first and second lateral cavities 33, 34. Moreover, the second dividing supporting wall 314 cooperates with the first and second main supporting wall 311, 312 for varying volumes of the third and fourth lateral cavities 35, 36.

The supporting portion 30 further comprises a third dividing supporting wall 317 extending from the bottom surface 12 of the puzzle plate 101 along the longitudinal direction X and connected with the first and second inner supporting walls 315, 316 and a fourth dividing supporting wall 318 extending from the bottom surface 12 of the puzzle plate 101 along the longitudinal direction X and connected with the first and second inner supporting walls 315, 316. The third and fourth dividing supporting walls 317, 318 are located between the first and second inner supporting walls 315, 316 and spaced apart to each other. The third and fourth dividing supporting walls 317, 318 are parallel to the first and second main supporting walls 311, 312. The first and second main supporting walls and the first through fourth dividing supporting walls are configured for improving the structural strength of the movable puzzle platform along the longitudinal direction X, respectively. The first and second inner supporting walls are configured for improving the structural strength of the movable puzzle platform along the lateral direction Y, respectively. The first and second inner supporting walls and the first through fourth dividing supporting walls are arranged between the first and second main supporting walls, respectively. The main supporting walls and the inner supporting walls can be assembled together by threads, snap-fit, friction fit, screws, rivets or other similar complementary conformation. The inner supporting walls and the dividing supporting walls can be assembled together by threads, snap-fit, friction fit, screws, rivets or other similar complementary conformation. Optionally, each of the main supporting walls, each of the inner supporting walls and/or each of the dividing supporting walls may be extended in any direction, spaced apart with each other and/or spaced apart from the bottom surface of the puzzle board as long as it is configured for improving the structural strength of the board assembly and/or forming the drawer cavity together with the puzzle plate.

The first main supporting wall 311 comprises a right first part 3111 connected with the first inner supporting wall 315, a left first part 3112 connected with the second inner supporting wall 316 and spaced apart from the right first part 3111 for forming a first opening 3113. The first longitudinal cavity 37 is formed by the first and second inner supporting walls 315, 316 together with the third dividing supporting wall 317. The first longitudinal cavity 37 is communicated with the first opening 3113, so that the corresponding puzzle drawer 32 can be slide in-and-out through the first opening 3113. The second main supporting wall 312 comprises a right second part 3121 connected with the first inner supporting wall 315, a left second part 3122 connected with the second inner supporting wall 316 and spaced apart from the right second part 3121 for forming a second opening 3123. The second longitudinal cavity 38 is formed by the first and second inner supporting walls 315, 316 together with the fourth dividing supporting wall 318. The second longitudinal cavity 38 is communicated with the second opening 3123, so that the corresponding puzzle drawer 32 can be slide in-and-out through the second opening 3123.

According to the first embodiment, the four lateral cavities 302 are formed at the transverse sides of the puzzle board 10 respectively. Particularly, the first and second lateral cavities 33, 34 are spacedly formed at each of the transverse sides of the puzzle board 10. The third and fourth lateral cavities 35, 36 are spacedly formed at each of the other transverse sides of the puzzle board 10. In other words, two corresponding puzzle drawers 32 are slidably coupled at each of the transverse sides of the puzzle board 10. Therefore, four puzzle drawers 32 are slidably coupled at the transverse sides of the puzzle board 10. It is worth mentioning that each puzzle drawer 32 is independently actuated to slide in-and-out of the corresponding lateral cavity 302. Since the puzzle drawers 32 are slidably coupled at the transverse sides of the puzzle board 10, each puzzle drawer 32 is relatively long enough and each drawer cavity 31 is deep enough to retain the puzzle drawer 32 therein so as to prevent the puzzle drawer 32 being slid out of the drawer cavity 31 accidentally or unintentionally when moving the puzzle board 10 on the playing surface. Accordingly, a length of each puzzle drawer is slightly smaller than half of the length of the puzzle board between the transverse sides thereof.

Each of the puzzle drawer 32 comprises a rectangular bottom panel 321 slidably received in the corresponding drawer cavity 31, a front panel 322 extending from the bottom panel 321, a back panel 323 extending from the bottom panel 321 and opposite to the front panel 322, a pair of side panels 324 extending from the bottom panel 321 for connected with the front panel 322 and the back panel 323. Optionally, each of the puzzle drawer 32 further comprises an anti-slipping layer 325 attached the bottom panel 321 for preassembling a group of puzzle pieces 100 to form a section of the puzzle figure and storing the puzzle pieces 100. Each of drawer cavity 302 comprises a gap 326 formed between the pair of side panels 324 and the corresponding supporting portion 301, thereby reducing the friction between the pair of side panels 324 and the corresponding supporting portion 301 when each of the puzzle drawer 32 is pulled and slid out of the corresponding drawer cavity 31.

The supplement arrangement 30 further comprises a drawer holder 304 provided at the puzzle board 10 to retain the puzzle drawers 32 in the drawer cavities 31 respectively. In this embodiment, the drawer holder 304 comprises a first magnetic element 331 provided at an inner wall of the drawer cavity 31 and a second magnetic element 332 provided at the puzzle drawer 32 to magnetically attract with the first magnetic element 331 so as to retain the puzzle drawer 32 in the drawer cavity 31. Due to the magnetically attracting force between the first and second magnetic elements 331, 332, the puzzle drawers 32 are held within the drawer cavities 31 respectively to prevent the puzzle drawer 32 being slid out of the drawer cavity 31 accidentally or unintentionally when moving the puzzle board 10 on the playing place. When a pulling force is applied at one of the puzzle drawers 32 to overcome the magnetically attracting force, the puzzle drawer 32 can be pulled and slid out of the drawer cavity 31.

In this embodiment, the first extending wall 51 is integral with a periphery of the first main supporting wall 311 as a whole for forming a first monolithic portion 55. The first monolithic portion 55 comprises a first receiving space 103 for fixing and receiving the fixing portion 102 of the puzzle board 10. The second extending wall 52 is integral with a periphery of the second main supporting wall 312 as a whole for forming a second monolithic portion 56. The second monolithic portion 56 comprises a second receiving space 104 for fixing and receiving the fixing portion 102 of the puzzle board 10. Optionally, a first monolithic portion further comprises a first fixing space positioned below the first receiving space and formed on the first main supporting wall for fixing and receiving one ends of the first and second inner supporting walls, respectively. A second monolithic portion further comprises a second fixing space positioned below the second receiving space and formed on the second main supporting wall for fixing and receiving another ends of the first and second inner supporting walls. When assembled, one ends of the first and second inner supporting walls are inserted into the first fixing space and are not exposed from the first main supporting wall of the first monolithic portion. Another ends of the first and second inner supporting walls are inserted into the second fixing space and are not exposed from the second main supporting wall of the second monolithic portion. The first receiving space is parallel to the first fixing space. The second receiving space is parallel to the second fixing space.

Therefore, the combination of the first extending wall 51, the puzzle board 10 and the first main supporting wall 311 is stable and reliable.
