Description

Technical Field

[0001] This utility model relates to a toy building block that utilizes magnets. Background Technology

[0002] Typically, magnetic toys containing permanent magnets are assembled into a three-dimensional structure with a predetermined shape by combining magnets with unit structural components made of linear, panel-shaped, or modular shapes, and using the magnetic force of the magnets.

[0003] As an example of the magnetic toy, there is a block-shaped magnetic toy made of a hexahedron or plastic material. The block-shaped magnetic toy has permanent magnets installed or embedded on each surface of the hexahedron. By utilizing the magnetic force of the permanent magnets, the blocks-shaped magnetic toy can be assembled into a three-dimensional structure with a predetermined shape through surface bonding.

[0004] In this situation, when the permanent magnet is fixed to the surface of the block, if the permanent magnets fixed to other blocks that are connected to the permanent magnet have the same polarity, a repulsive force will be generated instead of an attractive force, which will prevent the blocks from being joined together. Therefore, the blocks must be assembled with the polarity confirmed, which reduces the degree of freedom of assembly.

[0005] That is, existing building block toys that utilize magnets require the production of two types of building blocks, one with a magnet pointing in the north (N) direction and the other with a magnet pointing in the south (S) direction, which are then glued together to stack the blocks.

[0006] Therefore, when manufacturing and assembling existing magnetic building blocks, it is necessary to distinguish between the side of the block with the N pole magnet and the side with the S pole magnet. This makes the confirmation process during manufacturing complicated and poses risks in terms of time and cost. Furthermore, if the polarity of the magnet is incorrectly attached, it will result in more product defects. Due to the characteristics of magnets, it is also necessary to distinguish the two types of building blocks with different polarities by color and manufacture them separately, which is cumbersome.

[0011] This invention is based on the aforementioned situation. The purpose of this invention is to improve operability and production efficiency in the manufacture of building block toys by using the rotation of a cylindrical magnet to allow building blocks to be combined regardless of their magnetic poles.

[0012] According to a preferred embodiment for achieving the present invention's objective, the present invention's magnetic toy building blocks include: a building block body, which is polygonal in shape and has at least one fixing groove formed on its mating surface; a circular cover, which is inserted into and fixed in the fixing groove of the building block body; and a cylindrical magnet, which rotates by interaction with an external magnetic force while being embedded in the circular cover.

[0013] A circular groove is formed inside the circular cover for the cylindrical magnet to rotate.

[0014] Multiple fixing protrusions are formed along the circumferential direction on the outer side of the circular cover. The cylindrical magnet is accommodated by fixing the cover to the fixing protrusions.

[0015] The cylindrical magnet inside the circular cover rotates circumferentially based on its interaction with external magnetic forces, or rotates with the center of the circular cover as a reference.

[0016] The rotational force of the cylindrical magnet causes the circular cover to engage with the other circular cover regardless of the magnetic pole.

[0017] According to this utility model, a toy building block using magnets can be combined with the building blocks regardless of their magnetic poles by rotating a cylindrical magnet. This eliminates the need to distinguish between the positive and negative poles of the magnets during the pasting process, making assembly simple and shortening manufacturing time. Therefore, it avoids defective products caused by incorrect magnet orientation during pasting, thereby reducing manufacturing risks and improving assemblability.

[0018] Furthermore, since magnets can be glued together regardless of their magnetic poles, there is no need to manufacture two types of building blocks with different magnetic poles, thereby improving operability and production efficiency when making building block toys.

[0033] Hereinafter, an embodiment of the toy building blocks utilizing magnets according to the present invention will be described with reference to the accompanying drawings. In this description, the present invention is not limited to or restricted to this embodiment. Furthermore, in order to clarify the main points of the present invention, specific descriptions of known functions or structures may be omitted.

[0034] Figure 1 The figure illustrates a toy building block using magnets according to an embodiment of the present invention. Figure 2 The figure shows a circular cover with a built-in cylindrical magnet according to an embodiment of the present invention.

[0035] Reference Figure 1 and Figure 2 The toy building block 1 of this utility model using magnets includes a building block body 10, a circular cover 20 and a cylindrical magnet 30. When the cylindrical magnet 30 inside the circular cover 20 is combined with another circular cover 20, the magnets can be combined with each other regardless of their magnetic poles by rotating.

[0036] In this embodiment, the block body 10 of the toy block 1 is polygonal, and at least one fixing groove 11 is formed on the mating surface. The circular cover 20 is inserted into and fixed in the fixing groove 11 of the block body 10. The cylindrical magnet 30 rotates by interacting with external magnetic force while being built into the circular cover 20.

[0037] That is, the toy building block 1 is made by fixing the circular cover 20 to the fixing groove 11 formed in the building block body 10 with adhesive, and then covering the building block body 10 with sewn fabric. The building blocks are joined together by the magnetic force of the cylindrical magnet 30 built into the circular cover 20.

[0038] Furthermore, a circular groove 21 is formed inside the circular cover 20 for the cylindrical magnet 30 to rotate. The cylindrical magnet 30 can change the direction of its magnetic poles and rotate freely inside the circular groove 21 by external magnetic force.

[0039] Furthermore, a plurality of fixing protrusions 22 are formed along the circumferential direction on the outer side of the circular cover 20 of the toy building block 1. By fixing the cover 23 to the fixing protrusions 22, the cylindrical magnet 30 can be accommodated. In this case, grooves (not shown) that match the fixing protrusions 22 are formed on the cover 23 respectively. By inserting the fixing protrusions 22 into the grooves, the cover 23 is assembled to the circular cover 20.

[0040] Therefore, the toy building block 1 can be applied to a variety of sewn toys with the function of connecting magnets. Since the cylindrical magnet 30 built into the circular cover 20 can be combined with the circular cover 20 regardless of the direction of the magnetic poles of the magnet when it rotates under the action of magnetic force.

[0041] Figure 3 A diagram illustrating the rotational state of a cylindrical magnet according to an embodiment of the present invention. Figure 4 This diagram illustrates the assembled state of the circular cover of a toy building block according to an embodiment of the present invention.

[0042] Reference Figure 3 and Figure 4 The cylindrical magnet 30 built into the circular cover 20 rotates in the circumferential direction according to the interaction with the external magnetic force inside the circular cover 20 or rotates with the center of the circular cover 20 as a reference. The rotational force of the cylindrical magnet 30 enables the circular cover 20 to be combined with another circular cover 20 regardless of the magnetic poles.

[0043] That is, the cylindrical magnet 30 is disposed in the circular groove 21 of the circular cover 20 and can rotate 360° around the center of the circular cover 20. The cylindrical magnet 30 can also rotate around one side as a center along the circumference. The cylindrical magnet 30 can rotate freely in a clockwise or counterclockwise direction.

[0044] Therefore, by rotating the cylindrical magnet 30, it can combine with another cylindrical magnet 30 regardless of the magnetic poles. Thus, the circular cover 20 and the other circular cover 20 can combine with each other regardless of the magnetic poles of the cylindrical magnet 30.

[0045] Figure 5 A diagram illustrating a toy building block according to an embodiment of the present invention.

[0046] Reference Figure 1 and Figure 5 The manufacturing method of the toy building block 1 is described as follows: First, a circular cover 20 with a built-in cylindrical magnet 30 is manufactured. The circular cover 20 can be glued to each other regardless of the magnetic pole due to the rotation caused by the internal cylindrical magnet 30. Next, 24 fixing grooves 11 are cut by laser cutting on each of the 6 sides of the building block body 10, which is made of polyurethane hexahedral sponge (110mm×110mm), to accommodate the cylindrical magnet 30. Then, after the circular cover 20 with the built-in cylindrical magnet 30 is placed in the 24 fixing grooves 11, adhesive (EVA sponge adhesive) is applied to fix it. Finally, sewn fabric is covered on the building block body 10 with the circular cover 20.

[0047] Therefore, by rotating the cylindrical magnet, the building blocks can be combined regardless of their magnetic poles, eliminating the need to distinguish between the two poles of the magnet for bonding. This simplifies assembly and shortens manufacturing time, thus preventing defective products caused by incorrect magnet orientation, reducing risk and improving assemblability.

[0048] Furthermore, since magnets can be glued together regardless of their magnetic poles, there is no need to manufacture two types of building blocks with different magnetic poles, thereby improving operability and production efficiency when making building block toys.

[0049] As described above, the present invention has been illustrated and explained through preferred embodiments to illustrate the principles of the present invention, but the present invention is not limited to the described structure and function. Rather, those skilled in the art should understand that various changes and modifications can be made to the present invention without departing from the spirit and scope of the appended claims.
