Description

Technical Field

[0001] This utility model relates to the field of Rubik's Cube technology, and in particular to a flattened Rubik's Cube. Background Technology

[0002] The flattened cube is an irregularly shaped Rubik's Cube based on the design of the skewer cube. Its core feature is that by compressing the height of the cube, the traditional cube shape of the skewer cube is transformed into a flatter cuboid structure. This transformation not only changes the appearance but also subtly affects the feel of turning and the solution logic, making it a popular choice for Rubik's Cube enthusiasts exploring irregularly shaped structures.

[0003] Existing flattened Rubik's Cubes typically consist of a central axis and multiple cubes surrounding it. These cubes include two adjacent, relatively sliding first and second cubes. The first cube has a first side face, and the second cube has a second side face that rests against the first side face. The adjacent cubes are tightly pressed together to form the entire flattened Rubik's Cube. Depending on the cube's order, the cubes can be categorized as corner pieces, edge pieces, and center pieces. Players need to adjust the cube positions to reset the cube. However, existing flattened Rubik's Cubes also have several problems, primarily: the first and second sides are usually smooth surfaces, and prolonged contact increases the rotational friction. Furthermore, the cubes rely mainly on the player's twisting motion for position adjustment and alignment, increasing the time required to reset the cube.

[0004] Therefore, there is an urgent need to provide a flattened Rubik's Cube that can solve at least one of the above problems. Utility Model Content

[0049] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0052] It should be noted that when an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. When an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0053] refer to Figures 1-9 The present application provides a flattened Rubik's Cube, which includes a central axis 100 and a plurality of cubes 200. The plurality of cubes 200 are respectively disposed around the central axis 100. The plurality of cubes 200 include two adjacent first cubes 240 and second cubes 250 that can slide relative to each other. The first cube 240 has a first side 1000, and the second cube 250 has a second side 2000 that abuts against the first side 1000. At least one of the first side 1000 and the second side 2000 has an anti-stick groove 3000 formed on its surface. The space between the first side 1000 and the second side 2000 is filled with lubricating oil, and at least part of the anti-stick groove 3000 is filled with lubricating oil. First, the anti-stick groove 3000 allows air to enter, thus preventing excessive tightness and reducing frictional resistance. Second, lubrication through lubricating oil reduces frictional resistance and facilitates rotation. Furthermore, the anti-stick groove 3000 allows lubricating oil to be stored between the first side 1000 and the second side 2000 for a long time, maintaining lubrication and improving the operating feel.

[0054] It should be noted that the flattened Rubik's Cube in this application can be a flattened 2x2 Rubik's Cube, a flattened 3x3 Rubik's Cube, a flattened 4x4 Rubik's Cube, a flattened 5x5 Rubik's Cube, or a flattened Rubik's Cube of higher order.

[0055] Furthermore, in some embodiments, the first side 1000 and the second side 2000 are respectively formed with anti-stick grooves 3000. The anti-stick grooves 3000 are in the shape of a tortoise shell. Lubricating oil fills all the anti-stick grooves 3000, thereby storing more lubricating oil. The first side 1000 and the second side 2000 can carry lubricating oil through their respective anti-stick grooves 3000 for movement.

[0056] refer to Figures 1-9In some implementations, the flattened cube is an N-order cube, where N ≥ 3. Multiple cubes 200 include corner cubes 210, edge cubes 220, and center cubes 230: corner cubes 210 are located at the top corners of the flattened cube; edge cubes 220 are located at the edges of the flattened cube; the remaining cubes 200 are center cubes 230. A first magnet 300 is provided in the corner cube 210, and a second magnet 400 is provided in the edge cube 220. When the flattened cube is in its "returned" state, the first magnet 300 in the corner cube 210 faces the corresponding second magnet 400 in the adjacent edge cube 220, forming an attraction between opposite magnets. The "returned" state refers to the initial state where all cube faces are aligned, specifically as follows... Figure 1 As shown, the first cube 240 includes a corner cube 210, and the second cube 250 includes an edge cube 220 adjacent to the corner cube 210. By having the first magnet 300 in the corner cube 210 attract the corresponding second magnet 400 in the adjacent edge cube 220, the flattened cube can quickly align and return to its original position when rotated, thus reducing the time required for the player to restore the flattened cube.

[0057] Explanatoryly, when realizing the twisting and turning of the flattened Rubik's Cube, the existing arrangement of the cubes 200 and the arrangement of the cubes 200 and the central axis 100 can be used. The improvement of this application does not lie in this, so its working principle and structure will not be described in detail. Furthermore, there can be multiple first magnets 300 and a corresponding number of second magnets 400. For example, in a 3x3 flattened Rubik's Cube, corner piece 210 has three adjacent sides of edge piece 220, and edge piece 220 has two adjacent sides of corner piece 210. There can be three first magnets 300, with each side of corner piece 210 adjacent to edge piece 220 corresponding to one first magnet 300. There are two second magnets 400, with each edge piece 220 containing two second magnets 400. Each second magnet 400 corresponds one-to-one with the side of its adjacent corner piece 210. In the returned state, one first magnet 300 corresponds to one second magnet 400, forming a one-to-one correspondence. Please refer to the attached diagram for details.

[0058] Furthermore, in a multi-order Rubik's Cube with N greater than 4, in addition to the first cube 240 including corner piece 210 and the second cube 250 including edge piece 220 adjacent to corner piece 210, at least one of the two adjacent edge pieces 220 can also form an anti-sticking groove 3000.

[0059] In addition, in some implementations, in a multi-order Rubik's Cube with N greater than 3, corner piece 210, edge piece 220, and center piece 230 may each have an anti-sticking groove 3000, and there may be an anti-sticking groove 3000 between adjacent pieces.

[0060] In a 2x2 flattened Rubik's Cube, cube 200 is a corner piece 210 of the flattened Rubik's Cube, and all corner pieces 210 can have anti-stick grooves 3000.

[0061] In some implementations, reference Figures 1-9 The corner block 210 includes a corner block body 211 with a hollow cavity, and a first magnet 300 is fixed in the hollow cavity of the corner block body 211. The corner block body 211 with a hollow cavity is conducive to weight reduction. The edge block 220 includes an edge block body 221 with a hollow cavity, and a second magnet 400 is fixed in the hollow cavity of the edge block body 221. The edge block body 221 with a hollow cavity is conducive to weight reduction.

[0062] refer to Figures 1-9 In some embodiments, the corner block body 211 includes a first bottom cover 2111 and a first top cover 2112 detachably fitted onto the first bottom cover 2111. The first bottom cover 2111 and the first top cover 2112 enclose the hollow cavity of the corner block body 211. The first magnet 300 is detachably fixed to the inner wall of the first bottom cover 2111. The detachable split structure facilitates individual disassembly and replacement.

[0063] In some implementations, reference Figures 1-9 The main body 221 of the prism block includes a second bottom cover 2211 and a second top cover 2212 that is detachably fitted onto the second bottom cover 2211. The second bottom cover 2211 and the second top cover 2212 enclose and form a hollow cavity of the main body 221 of the prism block. The second magnet 400 is detachably fixed to the inner wall of the second bottom cover 2211. The detachable split structure makes it easy to disassemble and replace it individually.

[0064] refer to Figures 1-9 In some embodiments, the first bottom cover 2111 has a first insertion portion 21111, and the first top cover 2112 has a first insertion rod portion 21121. The first insertion rod portion 21121 is inserted into the first insertion portion 21111, so that the first top cover 2112 can be detachably covered on the first bottom cover 2111. The structure is simple and can achieve quick and convenient closing. The second bottom cover 2211 has a second insertion portion 22111, and the second top cover 2212 has a second insertion rod portion (not shown in the figure). The second insertion rod portion is inserted into the second insertion portion 22111, so that the second top cover 2212 can be detachably covered on the second bottom cover 2211. The structure is simple and can achieve quick and convenient closing.

[0065] In some implementations, reference Figures 1-9The corner piece 210 also includes a corner piece clip 212, which is fixedly connected to the corner piece body 211. A third magnet 500 is provided in the corner piece clip 212, and a fourth magnet 600 is provided in the central axis 100. When the flattened Rubik's Cube is in the return state, the third magnet 500 in the corner piece clip 212 faces the corresponding fourth magnet 600 in the central axis 100 and forms an opposite attraction. The third magnet 500 on the corner piece clip 212 and the fourth magnet 600 in the central axis 100 form an opposite attraction state, which helps the flattened Rubik's Cube to easily return to its original position before it is turned into its original position due to the opposite attraction.

[0066] Further, refer to Figures 1-9 In some embodiments, edge piece 220 further includes edge piece retainer 222, which is fixedly connected to the edge piece body 221. A fifth magnet 700 is disposed in the edge piece retainer 222, and the fifth magnet 700 in the edge piece retainer 222 and the corresponding fourth magnet 600 in the central axis 100 have a like-pole repulsive structure. This repeated process of corner attraction and edge repulsion helps to make the flattened Rubik's Cube easier to solve and also shortens the solving time. Corner attraction and edge repulsion refer to the corner piece 210 attracting the central axis 100 and the edge piece 220 repelling the central axis 100.

[0067] More specifically, see reference Figures 1-9 Taking a 3x3 flattened Rubik's Cube as an example, there are eight fourth magnets 600 on the central axis 100. The eight fourth magnets 600 and the eight third magnets 500 on the corner pieces 212 are attracted to each other. When a certain rotating layer of the flattened Rubik's Cube is rotated 45 degrees, the fifth magnets 700 on the twelve edge pieces 222 and the eight fourth magnets 600 on the central axis 100 are aligned. The fifth magnets 700 on the twelve edge pieces 222 and the eight fourth magnets 600 on the central axis 100 are like poles and repel each other. The resulting repulsive force and inertia will push the rotating layer forward. At this time, with a little more force, the third magnets 500 in the corner pieces 212 and the corresponding fourth magnets 600 on the central axis 100 will attract each other. The rotating layer will then be pulled back to its original position faster due to the attraction. Furthermore, the repeated assistance through the corner attraction and edge repulsion process makes the flattened Rubik's Cube easier to solve, shortens the solution time, and helps improve the feel of operation.

[0068] refer to Figures 1-9In some embodiments, the inner wall of the first bottom cover 2111 has a first groove 21110, and the first magnet 300 is embedded in the first groove 21110; the inner wall of the second bottom cover 2211 has a second groove 22110, and the second magnet 400 is embedded in the second groove 22110; the corner block retainer 212 has a third groove 2120, and the third magnet 500 is embedded in the third groove 2120; the surface of the central shaft 100 has a fourth groove 110, and the fourth magnet 600 is embedded in the fourth groove 110; the edge block retainer 222 has a fifth groove 2220, and the fifth magnet 700 is embedded in the fifth groove 2220. The structure is simple and reliably fixed.

[0069] Explanatoryly, the mating structures of the edge block latch 222 and the corner block latch 212 are based on existing technology, and this application does not improve upon them. The improvement in this application, as mentioned above, lies in the addition of a magnetic material. The edge block latch 222 and the edge block body 221 can be integrally formed.

[0070] refer to Figures 1-9 In some implementations, in a multi-order Rubik's Cube with N greater than 3, the center block 230 includes a center block body 231 and a connector (not shown in the figure). The center block body 231 is detachably and fixedly connected to the center axis 100 through the connector.

[0071] In some implementations, reference Figures 1-9 The central block body 231 includes a third bottom cover 2311 and a third top cover 2312. The third bottom cover 2311 includes a cavity with an opening facing away from the central shaft 100. The third top cover 2312 is inserted into the opening, and multiple notches 23111 are formed at the edge of the opening. The notches 23111 are configured to partially expose the portion of the third top cover 2312 inserted into the opening. The multiple notches 23111 are evenly spaced around the circumference of the opening. The connecting element is a fastening screw, and the third bottom cover 2311 is threadedly fixed to the central shaft 100 by the fastening screw. The design of the notches 23111 facilitates easier removal of the third top cover 2312 from the third bottom cover 2311 during toy assembly and disassembly. The evenly spaced notches 23111 around the circumference of the opening further reduces the difficulty of disassembly.

[0072] Further, refer to Figures 1-9The center pieces 231, corner pieces 211, and edge pieces 221 each have a single-color cover plate. Taking a 3x3 flattened cube as an example, the 12 edge pieces 221 are each made up of 24 single-color covers of 6 colors, combined in two-in-one combinations to form the second top cover 2212 of the edge pieces 221. The 8 corner pieces 211 are each made up of 24 single-color covers of 6 colors, combined in three-in-one combinations to form the first top cover 2112. The six center pieces 231 have a total of six single-color covers, with each single-color cover plate forming the third top cover 2312 of one center piece 231, thus making the six faces of the flattened cube independent into six different colored sides.

[0073] Finally, it should be noted that the technical features of the above embodiments can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features in the above embodiments have been described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0074] The above-described embodiments are merely one implementation of this utility model, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
