Description

Magnetically attached toy blocks

[0001] This technology relates to not only the production of a movable toy using toy blocks, but also to a toy block that can prevent loss of magnets when the toy block is separated for reasons such as maintenance.

[0002] Block toys, as a type of children's play equipment, are one of the most traditional and widely known toys.

[0003] Typically, a toy form is known in which a fastening projection protruding outward is formed on one side of the block to allow each block of different size and shape to be joined together, and a groove is formed on the other side to allow joining of another block.

[0004] And, from here, toys were developed that combined permanent magnets instead of the above-mentioned fastening protrusions and grooves.

[0005] Examples of toys incorporating such magnets are disclosed in the following documents:

[0006] With reference to FIG. 1, Republic of Korea Utility Model Registration No. 0233577 discloses a "building block toy formed of metal and magnets, in which a connecting point is formed on one or multiple surfaces of a building block, and if one side is a magnet (200), the opposite side is made of metal (100) inserted without protruding, so that the blocks can be easily combined and separated, and each block can be made into various shapes by assembling the side where the magnet (200) is inserted and the side where the metal (100) is inserted", and Domestic Utility Model Registration No. 0250911 discloses a "block composed of a main body having a receiving room having a certain size on the inside; permanent magnets that are divided into S and N poles in the upper and lower directions and are inserted and fixed in the receiving room in the order of S pole N pole, N pole S pole, and S pole N pole in the clockwise direction; and a cover that is integrally connected to the main body to prevent the permanent magnet from coming off".

[0007] However, toys using the magnets disclosed above had a problem in that it was difficult to make various changes in shape when combining blocks because the polarity of the magnets was fixed in a specific direction.

[0008] In addition, referring to FIG. 2, Korean Patent No. 0629306 discloses a block toy comprising a polyhedron block (31) formed across each face of the polyhedron, the interior of which is divided into a plurality of fluid spaces by partitions (W), and a linear groove-shaped fluid space (R) in which each open end is blocked from the outside by a blocking member (33); and magnets (32) placed in the fluid spaces at both ends of the block so as to be fluid, in order to solve the above problem.

[0009] However, in the above invention, there was a problem that the configuration of the block toy was complex, making it difficult to manufacture, and thus requiring a lot of manufacturing cost, and there was a high risk that the cap would be easily separated, resulting in loss of the magnet.

[0010] Meanwhile, in order to solve the above-mentioned conventional problems, another conventional technology known is 'Puzzle block using magnet (hereinafter referred to as 'puzzle block')', which is a domestically registered patent no. 1648055 proposed by the inventor of the present invention.

[0011] However, the above-mentioned conventional puzzle block has the advantage of allowing the blocks to be freely combined in any direction by the rotation of the magnet, being easy to manufacture and assemble, and being able to increase sturdiness, but it does not have a structure that can combine wheels, etc. for assembling a toy with mobility such as a car, and in particular, when making a plate shape with a certain area, it is inconvenient to make toys of various shapes because cubic puzzle blocks must be attached one by one.

[0012] Furthermore, in the case of conventional puzzle blocks, a stopper (65) is provided to prevent the magnets accommodated in the ceiling magnet accommodation chamber (13) and the floor magnet accommodation chamber (63) from being detached.

[0013] However, this closure member is structured to close the corresponding ceiling magnet receiving compartment and the corresponding floor magnet receiving compartment with one closure member when the cover (10) and the body (60) are combined with each other, so when the cover is opened, at least one of the ceiling or floor magnet receiving compartment must be in an open state, which causes a problem that one of the magnets received in each magnet receiving compartment may be lost.

[0014] In order to solve the above-mentioned conventional problems, the present invention aims to provide a toy block that can easily make toys of various shapes that are easy to move, such as automobiles, and can prevent loss of magnets when the cover and the body are separated from each other.

[0015] As a solution to the problem of the above-mentioned conventional problem, the magnetically attached toy block according to the present invention comprises a base block (100) formed by integrating at least two rows of unit blocks (10) in the horizontal and vertical directions, and an extension block detachably attached to the base block (100) and having a protrusion (250) formed on the outer surface into which at least one wheel (W) is detachably inserted, wherein the base block (100) and the extension block are characterized in that they are detachably attached to each other by the magnetic force of a magnet (M).

[0016] In addition, it is preferable that the base block (100) includes a first lower body (110) in the shape of a box with an open top and a first upper body (120) provided in the shape of a plate on the upper portion of the first lower body (110) so as to be fitted together by a stopper (30).

[0017] In addition, it is preferable that the base block (100) includes a plurality of first hollow holes (130) in which magnets (M) are accommodated, facing each other on the bottom surface of the first lower body (110) and the lower surface of the first upper body (120), and a plurality of second hollow holes (140) formed in the longitudinal direction on the inner surface of the first lower body (110) and in which magnets (M) are accommodated.

[0018] In addition, the first hollow hole (130) is opened and closed by an inserted plug (30), and the second hollow hole (140) is inserted by an insertion piece (20) that protrudes downward from the first upper body (120), and it is preferable that the plug (30) be inserted integrally with a plurality of first hollow holes (130).

[0019] In addition, the extension block is formed by integrally forming one unit block (10) or two or more unit blocks (10), and is preferably formed in the shape of a box with an open upper portion, and includes a second lower body (210, 210') provided with the protrusion (250) and a second upper body (220, 220') in the shape of a plate that opens and closes the open upper portion of the second lower body (210, 210') so that they are fitted together by a stopper (30).

[0020] In addition, it is preferable that the extension block includes a third hollow hole (230) in which a magnet (M) is received, facing each other on the bottom surface of the second lower body (210, 210') and the lower surface of the second upper body (220, 220'), and a fourth hollow hole (240) in which a number of magnets (M) are received, formed in the longitudinal direction on the inner surface of the second lower body (210, 210').

[0021] In addition, the third hollow hole (230) is opened and closed by a stopper (30), and the fourth hollow hole (240) is inserted with an insertion piece (20) that protrudes downward from the second upper body (220, 220'), and it is preferable that the stopper (30) be inserted integrally with a plurality of third hollow holes (230).

[0022] In addition, the integrally molded plug (30) includes a plurality of connecting bodies (31) formed in a columnar shape so that the upper and lower parts are each inserted into a plurality of first hollow holes (130) or a plurality of third hollow holes (230) in a shape-fitting manner, and a plurality of connecting bodies (33) formed by extending the plurality of connecting bodies (31) to be connected to each other, but it is preferable that the plurality of connecting bodies (33) adjacent to each other be reinforced by ribs (R).

[0023] In addition, the protrusion (250) is preferably formed with a cut groove (251) for insertion into the inside of the wheel (W) by varying the size of the outer diameter, and the wheel (W) is preferably formed with an insertion hole (Wa) for inserting the protrusion (250) on one or both sides.

[0024] In addition, it is preferable that a fitting projection (111) or a fitting groove (113) be formed on the outer surface of the base block (100) or the extension block so that it can be detachably coupled with another base block (100) or extension block.

[0025] According to the present invention, a movable toy can be made by magnetically attaching an extension block including wheels formed of the first and second embodiments to a base block, which is different from the conventional one, and, in the process of separating and connecting the first and second lower bodies and the first and second upper bodies to each other, it is expected that the loss of the magnet can be prevented through the configuration of a stopper provided in each of the first and third hollow holes, respectively.

[0045] Hereinafter, a magnetically attached toy block (hereinafter, simply referred to as a “toy block”) according to the present invention will be described in detail with reference to the attached drawings.

[0046] Before the explanation, in order to clearly understand the gist of the present invention, an example of making a car using toy blocks (1) is described below, but it should be noted that this is only one example, and it is also possible to make airplanes, ships, etc., as needed.

[0047] In addition, the base block (100) and the extension block described below are examples in which a single or multiple unit blocks (10) having a hexahedral shape are formed integrally, but it should be noted that this is only one example and is not limited thereto.

[0048] Furthermore, the magnet (M) accommodated in each hollow hole described below can be formed into a size and shape that allows free rotation within the hollow hole.

[0049] First, as shown in Fig. 4, the toy block (1) according to the present invention for forming the shape of a car largely includes a base block (100) and an extension block.

[0050] To explain in more detail, the base block (100) includes a first lower body (110) and a first upper body (120) as a configuration for forming the body of an automobile to be made into a toy, as shown in FIGS. 5 to 8.

[0051] For example, the base block (100) is integrally injection-molded so that a plurality of unit blocks (10) have two or more rows in each of the horizontal and vertical directions, and the first lower body (110) and the first upper body (120) have a structure that allows them to be separated and joined to each other.

[0052] As shown, the first lower body (110) is formed in the shape of a hollow box with an open upper portion, and the first upper body (120) is formed in the shape of a plate to open and close the open upper portion of the first lower body (110).

[0053] First hollow holes (130) that are vertically opposite to each other are formed on the bottom surface of the first lower body (110) and the lower surface of the first upper body (120), and a cylindrical magnet (M) is individually stored inside each first hollow hole (130).

[0054] Through this, another base block (100) or an extension block described later can be attached to the upper or lower part of the base block (100) in a magnetically detachable manner, thereby making it possible to create not only a car to be made into a toy, but also a shape such as a ship or airplane.

[0055] In addition, each first hollow hole (130) can prevent the magnet (M) stored in it from being detached through a separate stopper (30), and even when the first lower body (110) and the first upper body (120) are separated from each other through the combination of the stoppers (30), the loss of the magnet (M) stored in each first hollow hole (130) can be prevented.

[0056] Here, the separation connection between the first lower body (110) and the first upper body (120) can be achieved by a male-female connection between a connecting hole formed on the upper edge of the first lower body (110) and a connecting protrusion protruding downward from the lower surface of the first upper body (120) so that the connecting hole can be fitted into the shape.

[0057] Furthermore, in addition to the connection between the above-described connection hole and the connection protrusion, the first lower body (110) and the first upper body (120) may also have a connection means that can penetrate the connection hole (H) formed on the lower surface of the first lower body (110) and screw-connect with the connection hole (H) formed on the lower surface of the first upper body (120), thereby further enhancing the connection strength between them.

[0058] Meanwhile, the stopper (30) for separately connecting the first lower body (110) and the first upper body (120) described above may be selectively used in one embodiment among a structure including a coupling body (31) and a connecting body (33) so that a plurality of first hollow holes (130) can be opened and closed at once, as shown in FIGS. 6 and 7 and FIGS. 9 and 10, or a structure individually inserted into each first hollow hole (130) in a shape-fitting manner, as shown in FIG. 7, as a second embodiment.

[0059] Here, each of the combinations (31) according to the first embodiment is formed to have an overall columnar shape as shown, and the upper and lower parts can be fitted together by shape-fitting with a plurality of first hollow holes (130) facing each other.

[0060] To this end, a plurality of combinations (31) can also be arranged through a connecting body (33) so as to have the same pattern (checkerboard arrangement) as the first hollow hole (130).

[0061] As shown, the connector (33) is provided so that a plurality of connectors (31) can be connected to each other so that they can be integrated, thereby preventing loss of the connectors (31).

[0062] The plug (30') according to the second embodiment is inserted into the first hollow hole (130) in the same manner as the plug (30) in the first embodiment described above, as shown in FIG. 7, to prevent loss of the magnet (M).

[0063] However, the plug (30') in the second embodiment is different from the first embodiment in that it is formed as a single piece without a connecting body (33) and is individually inserted into the first hollow hole (130).

[0064] A plurality of second hollow holes (140) are formed on the inner surfaces of the first lower body (110) that face each other, that is, on the edges, in order to accommodate another magnet (M) in the height direction, thereby satisfying a structure in which another base block (100) as well as an extension block can be detachably attached to the side of the base block (100).

[0065] In particular, the magnet (M) stored in the second hollow hole (140) is formed with an insertion piece (20) protruding downward on the lower surface of the first upper body (120) to be inserted into the second hollow hole (140) so that the magnet (M) can always be positioned in the central part of the side of the base block (100).

[0066] Here, the insertion piece (20) may have a 'T' shape as well as a '-' shape as shown, and the insertion piece (20) inserted into the second hollow hole (140) is inserted to a depth such that the magnet (M) accommodated in the second hollow hole (140) can be fixed or rotated freely.

[0067] At this time, an auxiliary hole may be further formed in the second hollow hole (140) into which the insertion piece (20) is inserted and the fourth hollow hole (240) to be described later so that the insertion piece (20) can be inserted in a shape-fitting manner.

[0068] In addition, it is desirable that a chin portion be further formed inside the second hollow hole (140), and the magnet (M) is always positioned in the center of the second hollow hole (140) by inserting the chin portion and the insertion piece (20).

[0069] Furthermore, in the present invention, a lattice-shaped rib (R) may be further formed on each of the first lower body (110) and the first upper body (120).

[0070] In addition, the base block (100) of the present invention may further include a fitting projection (111) and a fitting groove (113) formed on each side (preferably the circumferential surface) to enable a separate connection with another base block (100'), as illustrated in FIG. 11.

[0071] Here, the insertion projections (111) and insertion grooves (113) can be formed in a single or alternate manner on the side of each base block (100) as shown, and the bonding force between a plurality of base blocks (100) coupled with the magnet (M) can be improved.

[0072] And, as shown in FIG. 4 and FIG. 12, the above extension block is detachably attached to the above-described base block (100) made to have the shape of a toy car by magnetic force, etc., and is configured to enable the base block (100) to move by a rotatable wheel (W).

[0073] Here, the extension block may use at least one of the first embodiment (200) in which a single unit block shape is used as illustrated in FIGS. 12 to 16, but wheels (W) are provided on one side, and the second embodiment (200') in which a plurality of unit blocks (10) are integrally formed as illustrated in FIGS. 17 to 21, and wheels (W) are provided on both sides thereof. Each embodiment will be described in detail below.

[0074] At this time, an insertion hole (Wa) is formed on one or both sides of the outer surface of the wheel (W) used in the first or second embodiment (200, 200') to satisfy a structure that is detachably coupled to a protrusion (250) formed protruding from the extension block according to the embodiment.

[0075] Before the explanation, the second lower body (210, 210') and the second upper body (220, 220') forming the extension block according to the first and second embodiments (200, 200') include the ribs (R) formed in the first lower body (110) and the first upper body (120) described above, but in order to clearly convey the gist of the present invention, a repetitive explanation of the ribs (R) will be omitted.

[0076] However, it should be noted that the ribs formed in the extension block may not have a lattice shape, unlike the base block (100) described above.

[0077] First, the extension block according to the first embodiment (200) includes, as shown in FIGS. 12 to 16, a second lower body (210) having a box shape with an open upper portion similar to the first lower body (110) described above, and a second upper body (220) having a plate shape that allows the open upper portion of the second lower body (210) to be opened and closed similar to the first upper body (120) described above.

[0078] Here, the second lower body (210) and the second upper body (220) have a structure in which they are separated and joined to each other through the fitting projection (111) and fitting groove (113) described above.

[0079] Third hollow holes (230) are formed on the bottom surface of the second lower body (210) and the lower surface of the second upper body (220) so as to face each other, and a magnet (M) is stored in each of the third hollow holes (230), and the magnet (M) stored through the third hollow hole (230) is prevented from being detached by insertion of a plug (30) having a single shape.

[0080] In addition, as illustrated, a fourth hollow hole (240) identical to the second hollow hole (140) described above can be formed on the inner surface of the second lower body (210), and a magnet (M) is stored inside the fourth hollow hole (240).

[0081] The magnet (M) housed in the fourth hollow hole (240) can be always positioned in the center of the fourth hollow hole (240) by inserting an insertion piece (20) that extends downward from the lower surface of the second upper body (220). For this purpose, a chin portion can be formed inside the fourth hollow hole (240).

[0082] Meanwhile, unlike the second hollow hole (140), the fourth hollow hole (240) may not be created at a location where a protrusion (250) is formed and extended on the outer surface of the second lower body (210). This is possible because the portion where the protrusion (250) is formed is not connected to another block (base block or extension block).

[0083] Here, the protrusion (250) formed in the shape of a cylinder has at least two or more cut grooves (251) formed in the longitudinal direction on the outer surface, as shown, so that the outer diameter of the protrusion (250) can be varied when combined with the wheel (W) to facilitate insertion, and a catch (253) is formed at the end so that after being inserted into the wheel (W), it hangs within the insertion hole (Wa) to prevent unwanted detachment unless an external force is applied.

[0084] In addition, as illustrated in FIG. 15, the insertion hole (Wa) formed in the wheel (W) so that the protrusion (250) can be inserted is formed on one side as well as on both sides so that the extension block according to the first embodiment can be placed on one side or both sides based on the wheel (W).

[0085] Furthermore, when a pair of wheels (W) are assembled on both sides of the extension block according to the first embodiment, it is noted that the extension block can also be combined using a plurality of unit blocks or rectangular parallelepiped unit blocks as needed (see Fig. 16).

[0086] In addition, as illustrated in FIGS. 17 to 21, the extension block according to the second embodiment (200') includes a second lower body (210') formed with a plurality of unit blocks having a predetermined length, and a second upper body (220') for opening and closing the open upper portion of the second lower body (210').

[0087] The second lower body (210') according to the second embodiment (200') is also formed in the shape of a box with an open top, and a third hollow hole (230) is formed on the bottom surface for storing a magnet (M) for each unit block (10), and the third hollow hole (230) is also formed on the lower surface of the second upper body (220').

[0088] In addition, the third hollow hole (230) formed in each of the second lower body (210') and the second upper body (220') is also closed by a separate stopper (30) to prevent the magnet (M) from being lost.

[0089] Here, it is noted that the plug (30) inserted into the third hollow hole (230) may be a plug (30) having one of the embodiments of the first embodiment in which the above-described plurality of combined bodies (31) are integrally formed by a connecting body (33) or the plug (30) according to the second embodiment in which the combined bodies (31) are individually formed.

[0090] In the second embodiment (200'), a plurality of fourth hollow holes (240) are formed on the inner surfaces of the second lower body (210') facing each other so that a magnet (M) can be accommodated therein, and the magnet (M) accommodated in the fourth hollow hole (240) satisfies a structure in which the magnet (M) is positioned in the center by the insertion piece (20) formed on the lower surface of the second upper body (220') and the protrusion formed inside the fourth hollow hole (240).

[0091] Furthermore, in the second embodiment (200'), the protrusions (250) having the cut grooves (251) are formed to protrude symmetrically on both sides to satisfy a structure in which a wheel (W) is fitted into each protrusion (250), and after being inserted into the wheel, it has a structure in which detachment is prevented by a catch (253).

[0092] Meanwhile, the second lower body (210') and the second upper body (220') according to the second embodiment (200') have a structure that can be opened and closed by means of a joining hole and a joining protrusion, and a rib (R) can be formed on the bottom surface of the second lower body (210') and the lower surface of the second upper body (220').

[0093] As described above, the toy block (1) according to the present invention can make a movable toy by magnetically attaching an extension block including a wheel (W) made of the first and second embodiments (200, 200') to the base block (100) in a manner different from the conventional one, and, in the process of separating and connecting the first and second lower bodies (110, 210, 210') and the first and second upper bodies (120, 220, 220'), it is expected to have the effect of preventing loss of the magnet (M) through the configuration of the stopper (30) provided in each embodiment in the first and third hollow holes (130, 230).
