Description

[Technical Field]

[0001] This invention relates to toy blocks that use magnets. [Background technology]

[0002] Generally, magnetic toys containing permanent magnets are configured so that the magnets are attached to unit components such as linear, panel, or block types, and the unit components can be assembled into a three-dimensional structure having a predetermined shape using the magnetic force of the magnets.

[0003] One example of such magnetic toys is a block-type magnetic toy made of a hexahedron made of wood or plastic. The block-type magnetic toy has permanent magnets attached or embedded on each surface of the hexahedron, and is configured so that a three-dimensional structure having a predetermined shape can be assembled by surface bonding between the block-type magnetic toys due to the magnetic force of the permanent magnets.

[0004] In this case, when the permanent magnet is fixed to the surface of the block, if the polarity is the same as that of the permanent magnet fixed to another unit block to be joined to it, a repulsive force, not an attractive force, is generated, making it impossible to join the unit block members. As a result, the unit block members must be assembled while checking the polarity, which reduces the degree of freedom in assembly.

[0005] In other words, conventional block toys using magnets require players to create two types of blocks, one with a north-pole magnet and one with a south-pole magnet on the surface, and then stack the blocks with their opposite poles facing each other.

[0006] Therefore, when manufacturing and assembling conventional magnetic blocks, the block side with the north pole magnet and the block side with the south pole magnet must be attached separately, which means that the procedures to be checked during manufacturing are complicated and involve significant risks in terms of time and cost. There is also the disadvantage that if the magnetic poles are attached incorrectly, there is a risk of many product defects occurring. There is also the troublesome problem that two types of blocks with different poles in terms of magnetic properties must be manufactured separately, distinguished by color.

[0008] The purpose of this invention was to take into consideration the above points, and is to provide a toy block that uses magnets, which can improve workability and productivity when making block toys by allowing blocks to be joined together regardless of their poles by rotating a cylindrical magnet. [Means for solving the problem]

[0009] According to a preferred embodiment for achieving the above-described object of the present invention, a toy block using magnets according to the present invention includes a polygonal block body having at least one fixing groove formed on a joining surface thereof, a circular cap inserted and fixed into the fixing groove of the block body, and a cylindrical magnet embedded in the circular cap that rotates by interaction with an external magnetic force.

[0010] The circular cap has a circular groove formed therein in which the cylindrical magnet can rotate.

[0011] A plurality of fixing protrusions are formed on the outer surface of the circular cap in the circumferential direction, and a cover is fixed to the fixing protrusions to accommodate the cylindrical magnet.

[0012] The cylindrical magnet rotates in the circumferential direction within the circular cap due to interaction with an external magnetic force, or rotates around the center of the circular cap.

[0013] The rotational force of the cylindrical magnet couples the circular cap to another circular cap regardless of the polarity. [Effects of the Invention]

[0014] According to the toy blocks using magnets of the present invention, blocks are connected to each other regardless of the poles by rotating the cylindrical magnet, so there is no need to attach the magnets with different poles, which simplifies assembly and reduces manufacturing time. This eliminates defects caused by attaching the magnets in the wrong direction, reduces manufacturing risks, and improves assembly efficiency.

[0015] In addition, since the blocks stick together regardless of the polarity of the magnets, there is no need to make two types of blocks with different polarities, which improves workability and productivity when manufacturing block toys. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0017] Hereinafter, an embodiment of a toy block using magnets according to the present invention will be described with reference to the accompanying drawings. However, the present invention is not limited to or constrained by the embodiment. In addition, when describing the present invention, detailed descriptions of well-known functions or configurations may be omitted in order to clarify the gist of the present invention.

[0018] Fig. 1 is a diagram showing a toy block using magnets according to an embodiment of the present invention, and Fig. 2 is a diagram showing a circular cap with a built-in cylindrical magnet according to an embodiment of the present invention.

[0019] Referring to Figures 1 and 2, the toy block 1 using magnets according to the present invention includes a block body 10, a circular cap 20, and a cylindrical magnet 30. When the cylindrical magnet 30 inside the circular cap 20 is combined with another circular cap 20, the magnets are combined with each other regardless of the polarity of the magnets by rotating.

[0020] In this embodiment, the block body 10 of the toy block 1 has a polygonal shape and has at least one fixing groove 11 formed on the joining surface, the circular cap 20 is inserted and fixed into the fixing groove 11 of the block body 10, and the cylindrical magnet 30 is rotated by interaction with an external magnetic force while being built into the circular cap 20.

[0021] That is, the toy block 1 is manufactured by fixing the circular cap 20 to the fixing groove 11 formed in the block body 10 with an adhesive, and then covering the block body 10 with a sewing material. The blocks are connected to each other by using the magnetic force of the cylindrical magnet 30 built into the circular cap 20.

[0022] The circular cap 20 has a circular groove 21 formed therein in which the cylindrical magnet 30 can rotate. The cylindrical magnet 30 can freely rotate within the circular groove 21 while changing its polarity according to an external magnetic force.

[0023] In addition, the circular cap 20 of the toy block 1 has a plurality of fixing protrusions 22 formed on its outer surface in the circumferential direction, and a cover 23 is fixed to the fixing protrusions 22 to accommodate the cylindrical magnet 30. In this case, grooves (not shown) that match the fixing protrusions 22 are formed in the cover 23, and the fixing protrusions 22 are inserted into the grooves, thereby assembling the cover 23 to the circular cap 20.

[0024] Therefore, the toy blocks 1 can be applied to various sewing toys having a function of attaching magnets, since the cylindrical magnets 30 built into the circular caps 20 can be rotated by magnetic force, and the circular caps 20 can be joined together regardless of the polarity of the magnets.

[0025] 3 is a view showing a rotating state of a cylindrical magnet according to an embodiment of the present invention, and FIG. 4 is a view showing a state in which a circular cap of a toy block according to an embodiment of the present invention is attached.

[0026] Referring to Figures 3 and 4, the cylindrical magnet 30 embedded in the circular cap 20 rotates in the circumferential direction within the circular cap 20 due to interaction with an external magnetic force, or rotates around the center of the circular cap 20, and the rotational force of the cylindrical magnet 30 couples the circular cap 20 to another circular cap 20 regardless of the pole.

[0027] That is, the cylindrical magnet 30 is installed in the circular groove 21 of the circular cap 20, and can rotate 360 ​​degrees around the center of the circular cap 20. The cylindrical magnet 30 can rotate in the circumferential direction around one surface. The cylindrical magnet 30 can rotate freely in either a clockwise or counterclockwise direction.

[0028] Therefore, the cylindrical magnet 30 can be connected to another cylindrical magnet 30 by rotating it regardless of the pole, and therefore the circular cap 20 can be connected to another circular cap 20 regardless of the pole of the cylindrical magnet 30.

[0029] FIG. 5 is a diagram showing a toy block according to an embodiment of the present invention.

[0030] Referring to Figures 1 and 5, the method of manufacturing the toy block 1 will be described. First, circular caps 20 with built-in cylindrical magnets 30 are manufactured. The cylindrical magnets 30 inside the circular caps 20 rotate, allowing them to stick to each other regardless of their polarity. 24 fixing grooves 11 (15 mm diameter) are cut out by laser cutting on six sides, four on each side, so that the cylindrical magnets 30 can fit into the block body 10, which is made of a regular hexahedron sponge (110 mm x 110 mm) made of polyurethane. The circular caps 20 with built-in cylindrical magnets 30 are then placed into the 24 fixing grooves 11, and adhesive (EVA sponge adhesive) is applied to fix them in place. Finally, the block body 10 with the circular caps 20 attached is covered with sewing fabric to complete the process.

[0031] Therefore, by rotating the cylindrical magnet 30, blocks can be joined together regardless of the poles, so there is no need to attach the magnets separately, which simplifies assembly and reduces manufacturing time. Therefore, defects caused by attaching magnets in the wrong direction are not generated, reducing the risk and improving assembly efficiency.

[0032] In addition, since the blocks stick together regardless of the polarity of the magnets, there is no need to make two types of blocks with different polarities, which improves workability and productivity when manufacturing block toys.

[0033] While the present invention has been shown and described in connection with preferred embodiments to illustrate the principles of the invention, the invention is not limited to the exact construction and operation shown and described. Rather, it will be readily apparent to those skilled in the art that numerous changes and modifications can be made to the invention without departing from the spirit and scope of the appended claims.
