Description

Technical Field

[0001] This utility model relates to the field of children's toy technology, and in particular to a magnetic toy. Background Technology

[0002] In recent years, with the continuous improvement of people's living standards and the increasing demands for quality of life, more and more attention has been paid to the upbringing of children, with most families prioritizing the intellectual development of young children. The market is flooded with various educational toys for early childhood development, such as magnetic tile toys. Magnetic tile toys are created by assembling various magnetic tiles into different shapes. Children can use their imagination to assemble models they like based on the shapes of the different magnetic tiles.

[0003] In the prior art, the magnets in the magnetic sheet are usually arranged in a long section in the middle of the edge of the magnetic sheet.

[0004] For example, a magnetic sheet toy authorized by patent number CN2022220870695 on December 23, 2022 includes a first outer plastic sheet, a second outer plastic sheet and an intermediate sheet. The intermediate sheet is provided with a magnetic component. The first outer plastic sheet and the second outer plastic sheet are adhered to the intermediate sheet and ultrasonically pressed together, so that the intermediate sheet and the magnetic component are wrapped inside the first outer plastic sheet and the second outer plastic sheet.

[0005] For example, a magnetic tile adhesive device authorized and announced on May 3, 2024, under patent number CN2023222060470 includes a building board body. The surface of the building board body has multiple placement slots, and the inner walls of the multiple placement slots are fixedly connected to magnetic pillars. The interior of the building board body has multiple cavities, and the inner walls of the multiple cavities are provided with limiting blocks. One side of the multiple limiting blocks is fixedly connected to a groove post. The surface of the multiple groove posts is provided with a first spring. Multiple slots are opened on both the front and back sides of the building board body, and the inner walls of the multiple groove posts are provided with reinforcement mechanisms.

[0006] The shortcomings of the existing technology are: the magnet is long, and although the magnetic pieces are misaligned during assembly, they are still connected, resulting in a loose stack of magnetic pieces that are easy to disintegrate, which affects the playability of magnetic toys. Utility Model Content

[0007] In order to overcome the above-mentioned shortcomings of the prior art, this utility model provides a magnetic toy that is stable when stacked, has a variety of shapes, and has high integrity when stacked.

[0008] To achieve the above objectives, the present invention adopts the following technical solution.

[0009] A magnetic toy includes several magnetic sheets stacked by magnetic force. Each magnetic sheet includes a polygonal main body. Several magnets are spaced apart along any edge of the main body so that at least two spaced regions along a single edge of the main body are magnetic. The main body includes a shortest edge, and the other edges of the main body are positive integer multiples of the shortest edge. The centers of adjacent magnets on any single edge of the main body are equidistant by a length L. The distance between the centers of magnets located at both ends of the same edge and their adjacent edge ends is L / 2.

[0010] Magnetic tiles can be stacked into various shapes through magnetic force, fully utilizing children's intelligence and promoting their intellectual development. The magnets in this application are spaced at least two points along each edge of the main body, providing multi-point synergistic magnetic attraction. Different magnetic tiles will not misalign during assembly, and the stacked structure is stable and not easily disintegrated, resulting in high playability for the magnetic toy. This application defines the shape of the main body, including its shortest edge, with other edges being positive integer multiples of the shortest edge. The main body can be a regular polygon, isosceles trapezoid, or rhombus, offering various structures and allowing for even more diverse stacking configurations, further enhancing the playability of the magnetic toy. Furthermore, this application specifies the position and spacing of the magnets. The centers of adjacent magnets on any single edge of the main body are equidistant by a length L. The distance between the center of the magnets at both ends of the same edge and the end of its adjacent edge is L / 2. When a magnetic sheet is assembled in a 1-to-many manner on one side, the distance between the two magnets corresponding to the adjacent ends of the magnetic sheet assembled on the same side is L, and the centers of other adjacent magnets are equidistant. Thus, the magnetic sheets can be stacked in a more compact manner without any gaps, further improving the playability of the magnetic toy.

[0011] Preferably, the length of the shortest edge is 2L. When the shortest edge is 2L, two magnets are set at the shortest edge, and the two magnets are located at the four equal division points at both ends of the shortest edge, so that the magnetic attraction of the magnets is reliable.

[0012] Preferably, the shape of the main body is a regular polygon. In one embodiment of the main body, each edge is the shortest edge.

[0013] Preferably, the main body is shaped like an isosceles trapezoid, where the shorter side and the leg are of equal length, and the longer side is twice the length of the shorter side. In one embodiment of the main body, the shorter side and the leg are the shortest edges.

[0014] Preferably, the main body has a convex arc surface along its edge. When the magnetic sheets are magnetically stacked, there may be a certain angle between them. The arc surface allows the magnetic sheets to rotate more smoothly, facilitating magnetic stacking when they are at an angle.

[0015] Preferably, the corners of the main body are rounded, and the length of the main body's edge is the same as the side length when the main body is not rounded. The rounded corners prevent sharp corners from appearing on the main body's edges, ensuring the safety of the magnetic sheet as a children's toy.

[0016] Preferably, the main body surface has several friction textures. This improves the gripping efficiency of the main body, enhances the playing experience, and also serves a decorative purpose, beautifying the magnetic sheet.

[0017] Preferably, the main body is equipped with an installation assembly, and the magnet is disposed within the installation assembly. The installation assembly has a receiving cavity for accommodating the magnet. The magnet is shaped as a rotating body, with its magnetic poles located on both sides of the rotation axis. The magnet is rotated within the receiving cavity. This rotation of the magnet within the receiving cavity allows it to rotate at a corresponding angle when the two magnetic sheets are stacked at an angle to maintain maximum magnetic connection.

[0018] Preferably, the mounting assembly includes a receiving member, a first connector, and a second connector. The receiving cavity is located within the receiving member and is open. The first connector and the second connector are located on opposite sides of the opening of the receiving cavity and are rotatable relative to the receiving member. Both the first connector and the second connector are L-shaped and interlock. The main body has a hollowed-out positioning post. After the receiving member, the first connector, and the second connector are connected, they grip the positioning post. The mounting assembly holds the magnet through the receiving member, and the interlocking of the first connector and the second connector ensures that the mounting assembly grips the positioning post, providing a reliable connection. When the mounting assembly grips the positioning post, the opening of the receiving cavity is also blocked by the positioning post, preventing the magnet from falling out and ensuring reliable magnet placement.

[0019] Preferably, the main body has a notch, and the positioning post spans the opposite wall of the notch. The size of the notch wall is larger than that of the positioning post to form a receiving groove surrounding the positioning post. The receiving component, the first connector, and the second connector are concealed within the receiving groove so that the outer surface of the mounting component is flush with the surface of the main body. This concealed installation of the mounting component within the receiving groove ensures the integrity of the magnetic sheet surface, avoids sharp edges, and guarantees the safety of using the magnetic sheet.

[0031] In the description of this utility model, it should be understood that the technical features defined by terms such as "first" and "second" which have a sequential concept are only for the purpose of clearly describing the defined technical features and making the defined technical features clearly distinguishable from other technical features, and do not represent that they are named in this way in actual implementation. Therefore, they should not be construed as limitations on this utility model.

[0032] One embodiment of this utility model discloses a magnetic toy, such as... Figures 1 to 8As shown, the toy includes several magnetic sheets stacked by magnetic force. Each magnetic sheet includes a polygonal main body 1. Each set of magnetic toys can use magnetic sheets of the same shape and size, or it can use any number of magnetic sheets of different shapes. In this embodiment, the main body 1 includes... Figure 8 The equilateral triangle shown, such as Figure 4 and Figure 6 The square and other regular polygons shown are included. This also includes, for example, regular polygons such as... Figure 1 The isosceles trapezoid shown, in such a case Figure 1 In the magnetic sheet shown, the main body 1 is shaped like an isosceles trapezoid, with the shorter side and the legs being of equal length, and the longer side being twice the length of the shorter side. In the aforementioned magnetic sheet, several magnets 2 are spaced apart along any edge of the main body 1 so that at least two spaced regions along a single edge of the main body 1 possess magnetic force. The main body 1 includes the shortest edge, and the other edges of the main body 1 are positive integer multiples of the shortest edge. The centers of adjacent magnets 2 on any single edge of the main body 1 are equidistant by a length L. The distance between the centers of magnets 2 located at both ends of the same edge and their adjacent edge ends is L / 2.

[0033] In such Figure 1 In the magnetic sheet scheme shown, the shortest side of the isosceles trapezoid, consisting of the shortest side and the leg, has a length of 2L. The long side of the isosceles trapezoid has a length of 4L.

[0034] In such Figure 4 In the scheme shown, all four sides of the square are the shortest edges, and the length of the shortest edge is 2L.

[0035] In such Figure 8 In the scheme shown, all three sides of the equilateral triangle are the shortest sides, and the length of the shortest side is 2L.

[0036] When used as a complete toy, the long side of an isosceles trapezoid can be connected to two square magnetic pieces or two equilateral triangular magnetic pieces, etc.

[0037] Magnetic tiles can be stacked into various shapes through magnetic force, fully utilizing children's intelligence and promoting their intellectual development. In this application, the magnet 2 is positioned at least twice along a single edge of the main body 1, providing multi-point synergistic magnetic attraction. Different magnetic tiles will not misalign during assembly, resulting in a stable stacked structure that is not easily disintegrated, thus enhancing the playability of the magnetic toy. This application defines the shape of the main body 1, including its shortest edge, with other edges being positive integer multiples of the shortest edge. The shape of the main body 1 can be a regular polygon, isosceles trapezoid, or rhombus, offering various structures and allowing for the formation of even more diverse stacking structures, further improving the playability of the magnetic toy. Furthermore, this application specifies the position and spacing of the magnets 2. The centers of adjacent magnets 2 on any single edge of the main body 1 are equidistant by a length L. The distance between the center of the magnets 2 located at both ends of the same edge and the end of its adjacent edge is L / 2. When multiple magnetic sheets are assembled on one side of the magnetic sheet, the distance between the two magnets 2 corresponding to the adjacent ends of the magnetic sheets assembled on the same side is L, and the centers of other adjacent magnets 2 are equidistant. Thus, the magnetic sheets can be stacked in a more compact manner without any gaps, further improving the playability of the magnetic toy.

[0038] The surface of the main body 1 has several friction marks 3. Figure 1 In the magnetic sheet shown, the friction pattern 3 on the main body 1 is an equilateral triangle or an approximately equilateral triangle. Figure 2 In the magnetic sheet, the friction pattern 3 on the main body 1 is petal-shaped. Figure 6 In the magnetic sheet shown, the main body 1 has a hollowed-out area in the middle for easy handling. And as in... Figure 8 In the magnetic sheet shown, the friction pattern 3 on the main body 1 is also an equilateral triangle.

[0039] As one embodiment of this utility model, a magnetic toy is disclosed, such as Figure 5 , Figure 6 and Figure 7 As shown, the main body 1 has a convex arc surface 4 along its edge. The cross-sectional shape of the arc surface 4 is semi-circular. The corners of the main body 1 have transition fillets 5, and the length of the edge of the main body 1 is the same as the side length of the main body 1 without the transition fillets 5. When the magnetic sheets are magnetically stacked, there may be a certain angle between them. The arc surface 4 allows the magnetic sheets to rotate more smoothly, facilitating the magnetic stacking when they are at an angle.

[0040] The main body 1 is equipped with an installation component 6. The magnet 2 is disposed within the installation component 6. The installation component 6 has a receiving cavity 8 for accommodating the magnet 2. The magnet 2 is shaped as a rotating body, with its magnetic poles located on both sides of the rotation axis. The magnet 2 is rotated within the receiving cavity 8. Specifically, the installation component 6 includes a receiving part 7, a first connecting part 9, and a second connecting part 10. The receiving cavity 8 is located within the receiving part 7 and is open. The first connecting part 9 and the second connecting part 10 are located on opposite sides of the opening of the receiving cavity 8 and are rotatable relative to the receiving part 7. Both the first connecting part 9 and the second connecting part 10 are L-shaped. The outer end of the first connecting part has a protruding tooth 11, and the end of the second connecting part has a groove 12. The protruding tooth 11 and the groove 12 cooperate to achieve the engagement of the first connecting part 9 and the second connecting part 10. The main body 1 has a hollowed-out positioning post 101. After the receiving part 7, the first connecting part 9, and the second connecting part 10 are connected, they clamp tightly to the positioning post 101. The positioning post 101 has a rectangular cross-sectional shape. The main body 1 has a notch, and the positioning post 101 spans the opposite wall of the notch. The size of the notch wall is larger than that of the positioning post 101 to form a receiving groove 102 surrounding the positioning post 101. The receiving member 7, the first connecting member 9, and the second connecting member 10 are hidden within the receiving groove 102 so that the outer side of the mounting assembly 6 is flush with the surface of the main body 1. The L-shaped structure of the first connecting member 9 and the second connecting member 10 has good elastic deformation capability, which allows the protrusion 11 and the groove 12 to have a certain positional adjustment capability, facilitating the engagement of the protrusion 11 and the groove 12 on one side of the positioning post 101. In this embodiment, a first recess 13 is provided at the junction of the first connecting member 9 and the receiving member 7, and a second recess 14 is provided at the junction of the second connecting member 10 and the receiving member 7. The first connecting member 9 can rotate around the first recess 13 relative to the receiving member 7, and the second connecting member 10 can rotate around the second recess 14 relative to the receiving member 7.

[0041] Furthermore, the first connector 9 has a protruding insertion post 15, and the second connector 10 has a recessed slot 16. When the first connector 9 and the second connector 10 are engaged, the insertion post 15 and the slot 16 are simultaneously inserted, improving the reliability of the connection between the first connector 9 and the second connector 10. When the first connector 9 and the second connector 10 are engaged, the engagement and insertion positions are located between the positioning post 101 and the main body 1, forming a concealed arrangement, resulting in high anti-detachment performance of the first connector 9 and the second connector 10.
