The present invention relates to a magnetic play toy that can be freely adjusted in length and linearly deformed. More specifically, the upper connection member is provided with magnets and spherical inserting projections at the upper and lower ends, and the hemispherical insert grooves at the upper and lower ends are opposite to the upper connection member. And a lower connecting member each provided with a magnet and a plurality of intermediate connecting members each having a hemispherical groove and a spherical inserting protrusion at upper and lower ends thereof. By connecting the intermediate connecting member and the lower connecting member of the member in order to be rotated sequentially, each joining part acts as a joint, thereby allowing free movement between each member and the member. Not only various linear deformations are possible, but also the number of the intermediate connecting members coupled between the upper and lower connecting members. The present invention relates to a magnetic play toy free of length adjustment and linear deformation, which can be freely and easily adjusted between the upper and lower connection members as necessary.

Among many children's toys, Lego is one of the most popular toys sold around the world because it helps children's creativity increase and is suitable to play with them for a long time, not for a short time.

The LEGO is a toy that is very helpful in improving children's imagination and creativity by assembling various shapes according to their own tastes and ideas. By changing the size at a certain ratio, it is possible to assemble parts of different sizes together.

However, in order to make a specific shape, the lego is subject to constraints that require a specific shape part suitable for the shape, and each part is a three-dimensional shape based on a cuboid or a cube. Having a large volume of the parts is difficult to store, there is a problem that takes too much time to assemble a particular shape because it takes a lot of time to find a particular part among the many lego parts collected.

Solving the above shortcomings of Lego, and because there is no formal basic sculpture shape related to a specific theme, magnetic play toys have been developed that are beneficial for cultivating geometric creativity without being influenced by preconceived notions when creating sculptures. Same as

In general, the conventional magnetic play toy is wrapped with a synthetic resin outer shell, and composed of a magnetic stick and a metal sphere coupled to both ends of the metal rod permanent magnets, the plurality of magnetic sticks continuously through the metal sphere It is a toy that allows you to create the model or structure you want by making connections.

In other words, strictly speaking, it is possible to create a three-dimensional model of various sculptures by using a magnetic stick that acts as a two-dimensional line and a metal sphere that acts as a one-dimensional point, although it has a three-dimensional volume. It is the magnet play toy that can improve the understanding and creativity of the perceptual ability and the geometrical sculpture.

Representative embodiments of the above-described conventional magnetic play toys are briefly described with reference to FIGS. 1 to 2.

1 is a perspective view showing a state of use of a conventional magnetic play toy, Figure 2 is a cross-sectional view showing a basic assembly structure and a cross-sectional view of the magnetic stick constituting the conventional magnetic play toy.

As shown in the drawing, the conventional magnetic play toy has an outer circumferential surface of the permanent rod 11 and the outer circumferential surface of the permanent rod 11 and the metal rod 12 and the permanent magnet 11 in which discs or cylindrical permanent magnets 11 are in close contact with both end surfaces thereof. (S) is composed of a magnetic stick (1) and the metal sphere (2) covering the edge portion together with a synthetic resin jacket (13), a plurality of magnetic sticks (1) can be connected via each metal sphere (2). It is a structure.

The magnet stick 1 is a disc-shaped permanent magnet 11 is closely coupled to both front end surfaces of the metal rod 12, so that the magnet stick 1 becomes a bar magnet, one side of which is the N pole, the other side of the S pole It will show polarity.

Each end surface of the magnet stick 1 is attached to the surface of the metal sphere 2 by a magnetic force, and the connection structure is a triangular structure, which is the most basic structure. Structure models of various shapes will be created.

The conventional magnetic play toy as described above is composed of a metal sphere serving as a one-dimensional point and a magnetic stick serving as a two-dimensional line, so that its volume is minimized when stored, and the parts are attached by permanent magnets, so it may be lost. Although it has a small advantage, it is only suitable for geometric models consisting of only points and straight lines, and it is impossible to create a curved shape such as a circular shape, or even a straight magnet stick and a metal sphere must be used to create a curved shape. There is a problem that becomes large.

In other words, in order to make sculptures of various shapes using a magnet stick, not only a magnet stick deformed into an arc shape but a straight line, but also a magnet stick bent at various angles and length ratios, etc., but a conventional magnetic play toy does not satisfy this. Because of this, the shape of the sculpture can be made relatively simple, or the size was very large.

Magnetic play toys for solving the problems of the above-mentioned magnet play toys are disclosed in Korean Utility Model Registration Application No. 02-35767 (quotation design 1) and No. 02-26771 (quotation design 2).

As shown in FIGS. 3 to 4, the magnet stick 30 of the above-mentioned proposal 1 may include a small metal center hole 33 between the metal pin 31 (corresponding to the 'metal rod') and the metal pin 31 ′. ) And the permanent magnets 32 and 32 'are attached to the outer end faces of the one metal pin and the other metal pin, respectively, and the two metal pins (including the front end edges of the two permanent magnets 32 and 32'). 31) (31 ') and the entire center sphere 33 is a structure surrounding the outer shell 34 of the synthetic resin material.

Therefore, the entire magnetic stick 30 surrounded by the outer shell 34 is bent around the center hole 33, and thus, it is possible to make more various shapes than the simple linear magnetic stick. Only two magnets can be bent while the two sides of the straight magnet stick have a fixed angle between them, so that only a magnetic arc can be used to create a smooth arc. After the bending angle of the bend is small and a plurality of magnet sticks must be connected, the overall radius of curvature is increased so that a small shaped sculpture cannot be made.

In addition, the cited proposal 2, as shown in Figure 5, the magnetic steel in a variety of shapes, such as semi-circular (41), 1/4 round 42, right angle bend 43, obtuse bent 44 Although it is possible to make the sculptures of a variety of shapes, but the variety, but the shape of the sculptures can not be limited, the shape also has a disadvantage that can only be dependent on the shape of the magnetic stick made, form As the number of magnet sticks increases, it takes time to select an appropriate one of them, so that it takes a long time to make a sculpture as a play, and manufacturing productivity decreases by making various types of magnetic sticks.

That is, the above-mentioned proposal 1 is not only deformable so that one magnet stick has curvature over the entire length of the stick, but also the length of both sides of the bent portion is always constant as the bent portion is always fixed. There is a limitation, and since the proposal 2 is fixed in one form of the magnetic stick, there is a disadvantage that it can only be used for the same purpose all the time.

In addition, since both of the above-mentioned proposals fix the entire length of the magnet stick, it is possible to make only a sculpture having a length possible by a combination of a plurality of prepared magnet sticks.

For example, if a magnet stick of the same length is provided, an equilateral triangle is possible, but the two magnet sticks are on both sides, and a right triangle having a 90 ° angle between them, or a rectangle whose curvature is not an integer multiple of the vertical length, and the curvature is changed. It is difficult to make such a line segment, and it is difficult to make a sculpture having various dimensions and curvatures, and there is a problem that only a sculpture having a geometrical shape possible with the prepared magnetic stick is required.

In order to solve the problem of the deformation of the magnet sticks of the two cited documents, a magnetic stick coated with a synthetic resin on the outer circumferential surface of one metal wire or a wire twisted with a plurality of metal wires is used as a core. 19589 (quotation 3).

In the case of Proposition 3, the linear deformation of the magnet stick is freed because the flexible metal wire or wire is used as the core, unlike Proposals 1 to 2, but this also has the disadvantage that one magnet stick is fixed to one length. Structurally, there are the following problems.

That is, when the resin is coated on the outer circumferential surface of the metal, deformation thereof is promoted by changing the length between the metal and the synthetic resin interface, and in severe cases, the number of deformation increases, such as the synthetic resin swells from the outer circumferential surface of the metal. As a result, there is a problem that cracks may occur in the synthetic resin or damage of the magnet stick due to breakage of the metal wire.

The present invention was devised to solve all the problems of the conventional magnetic play toys as described above, and can easily extend or shorten the length of one linear magnet stick as necessary, and center the bent portion when bending. The length ratio of both bends can be freely adjusted as needed, and the deformation can be made to have a large number of curvatures including a straight part in one linear magnet stick, thereby creating a sculpture without limiting the shape. It is an object of the present invention to provide a magnetic play toy that can be.

The object of the present invention is achieved by a spherical insertion protrusion, and a hemispherical insertion groove in which the insertion protrusion is inserted.

Magnetic play toys of the present invention can be freely adjusted in length and linearly deformed, and a plurality of detachable magnets are rotatably coupled with respect to each other. The terms 'top', 'middle' and 'bottom' will be used.

The magnetic play toy of the present invention which is free of length adjustment and linear deformation divides one magnet stick into a plurality of parts which can be detachably combined. The articulation of each part and the joint of the part to provide a plurality of joints, that is, multiple joints in one magnet stick, a technical feature of the bent portion, the curvature having a specific angle in one magnet stick by the articulation It is possible to simultaneously form various types of linear deformation parts such as a bending part having a structure, and to allow the number of joints to be easily added or subtracted so that the length of the entire magnet stick can be freely extended or shortened as necessary.

As described above, the coupling part serving as a free-moving joint is made of a hemispherical insertion groove into which a spherical inserting protrusion and an inserting protrusion are inserted, and a magnetic stick, which is a magnetic play device of the present invention, which is free of length adjustment and linear deformation by such a joint structure. The upper connection member with a magnet, and the plurality of intermediate connection members and the lower connection member with the magnet are rotatably coupled to each other about a coupling part with respect to each other in a straight line in a series order. Same as

The upper and lower connection members serve as a connection part for connecting the magnetic stick and the magnetic stick in the state where the magnetic metal sphere is interposed. The upper connection member has a magnet at the upper end and a spherical insertion protrusion protrudes at the lower end. The lower connection member has a hemispherical groove formed at the upper end and a magnet provided at the lower end, each of which has a magnetic metal ball attached to the magnets provided at the upper and lower ends of the upper and lower connection members, respectively. The upper and lower connecting members of the other magnetic sticks are connected to the metal sphere.

In addition, the intermediate connecting member coupled between the lower end of the upper connecting member and the upper end of the lower connecting member has a structure in which a hemispherical insertion groove is formed at the upper end of each of the spherical inserting protrusions at the lower end thereof, and the insertion protrusion at the lower end of the upper connecting member is the first intermediate member. Rotating and detachably inserted into the insertion groove of the upper end of the connecting member, the insertion protrusion of the lower end of the first intermediate connecting member is inserted into the insertion groove of the upper end of the second intermediate connecting member in a manner that a plurality of intermediate connecting members are sequentially joined and finally The lower end insertion protrusion of the intermediate connection member is inserted into and coupled to the insertion groove of the upper end of the lower connection member having the magnet at the lower end thereof, thereby completing one magnet stick.

At this time, the insertion protrusion inserted into the hemispherical insertion groove is freely rotatable and the insertion protrusion should not escape from the insertion groove unless an external force of a predetermined force is applied, and the insertion groove should be somewhat larger than the hemisphere.

That is, the opening diameter of the insertion groove for inserting the insertion protrusion into the insertion groove is smaller than the inner diameter of the insertion groove and the diameter of the insertion protrusion so that the insertion protrusion does not escape from the insertion groove.

At this time, the insertion protrusion and the insertion groove is preferably a synthetic resin material having a suitable elastic bar, even if the opening diameter of the insertion groove is smaller than the diameter of the insertion protrusion when the force is applied, the insertion protrusion enters into the insertion groove, the inserted state The insertion protrusion into the insertion groove is not caught by an opening having a small diameter unless the external force is given a predetermined size.

As described above, an audible effect sound is generated so that the movement of the insertion protrusion, which is freely rotated in the state where the insertion protrusion and the insertion groove are combined, is generated, and the insertion protrusion is caused by the weight of the connecting member without an external force. It is preferable that each of the plurality of protrusion grooves arranged at regular intervals on the inner circumferential surface of the insertion groove is provided with one protruding stop protrusion on the outer circumferential surface of the insertion protrusion so as to prevent itself from being rotated at the inner circumference of the insertion groove.

That is, the stop projection protruding to the outer peripheral surface of the insertion protrusion is inserted into any one of the projection groove of the inner peripheral surface of the insertion groove in accordance with the rotation of the insertion projection is prevented the rotation of the insertion projection in a state where a constant force is not applied, When the insertion projection is rotated, the stop projection of the outer circumferential surface is released from the projection groove and then inserted into another projection groove to generate a click sound, which can be seen that the insertion projection is rotated and fixed to another position.

At this time, on the contrary, the stop projection may be formed on the inner circumferential surface of the insertion groove, and a plurality of projection grooves may be formed on the outer circumferential surface of the insertion projection.

Matters relating to the technical construction and the effect of the above object of the present invention magnetic play toy will be clearly understood by the following detailed description with reference to the drawings showing preferred embodiments of the present invention.

Fig. 6 is a perspective view of an embodiment of the present invention magnetic play toy, Fig. 7 is a sectional view of each member constituting the embodiment of the present invention magnet play toy, Fig. 8 is an insertion groove cross section, and Fig. 9 is a combination of two members. 10 is a cross-sectional view of the insertion protrusion formed with the stop projection in FIG. 10, and a cross-sectional view of the insertion groove in which the protrusion groove is formed in FIG.

Prior to the description of the present invention, in order to avoid confusion in terms, a cross section perpendicular to the direction of the plan view is defined as a planar section, and a cross section perpendicular to the direction of the front view is defined as a front section.

As shown in the figure, the magnetic play toy of the present invention has a columnar main body 51A in which a disc or a cylindrical permanent magnet M is embedded in the upper end so that the upper surface is exposed to the outside through the upper end surface, and a flat cross-sectional area toward the lower side. Or the upper connection member consisting of a lower auxiliary body (51B) having a spherical inserting protrusion (E) is provided in the lower end of the main body (51A) extending downward from the lower end of the main body 51A having a spherical insertion protrusion (E) at the bottom 511;

Hemispherical insertion groove (G) is formed in the upper end of the spherical insertion protrusion (E) of the upper connection member 511 to be inserted and detachably detachable, and the cross-sectional area or diameter including the insertion groove (G) gradually decreases downward. An upper auxiliary body 52A having a forward cross-sectional shape having a shape of an inverted funnel, a columnar main body 52B extending downward from a lower end of the upper auxiliary body 52A, and having a constant cross-sectional area or diameter; As the flat cross-sectional area or diameter gradually decreases toward the lower end of the main body 52B extends downward, the front cross-sectional shape of the funnel and the lower auxiliary body 52C provided with a spherical insertion protrusion (E) at the lower end. A plurality of intermediate connection members 521;

Hemispherical insertion groove (G) is formed at the upper end and the spherical insertion protrusion (E) of the intermediate connecting member (521) is detachably and rotatably inserted and has a flat cross-sectional area or diameter including the insertion groove (G) toward the bottom. The upper auxiliary body 53A gradually increasing to form a reverse funnel, and a disc or a cylindrical permanent magnet M is embedded in the lower end so that the bottom is exposed to the outside through the lower end of the upper auxiliary body 53A. It consists of a lower connecting member 531 consisting of a columnar main body 53B extending downward from the lower end of the 53A.

At this time, the main body 51A, 53B of the upper and lower connection members in which the permanent magnet M is embedded has a slightly larger flat cross-sectional area of each of the upper and lower parts of the total length of which the permanent magnet is embedded. It may be made to have a constant cross-sectional area over its entire length.

At this time, the insertion protrusions E and the insertion grooves G provided in each of the members 511, 521, and 531 have the same size and shape.

And, all the members except the permanent magnet (M) is preferably made of a synthetic resin having a suitable rigidity and elastic force, the insertion protrusion (E) is inserted into the insertion groove (G) of the insertion groove (H) of the insertion groove. ) So that the opening diameter (R ') of the insertion groove (G) is slightly smaller than the inner diameter (R) of the insertion groove (G) and the diameter of the insertion protrusion (E) so as not to fall out when no artificial external force is applied. It is good to form the insertion groove (G), the actual content of the insertion groove (G) is formed somewhat larger than the content of the hemisphere.

When there is a difference between the inner diameter of the insertion groove (G) and the diameter (R ') of the opening as described above, the smaller the difference can be easily coupled and separated between the insertion protrusion (E) and the insertion groove (G), The larger the difference is, the more difficult it is to insert and separate. Therefore, the diameter (R ') of the insertion groove opening (H) is smaller than the inner diameter (R) of the insertion groove, but more preferably 90% or more, less than 90% In some cases, it may be difficult to insert and remove the insertion protrusion depending on the material.

In addition, the flat cross-sectional shape of the entire body (51A, 51B) (52A, 52B, 52C) (53A, 53B) constituting each member is not limited to the shape, such as circular, oval, polygon, etc., insertion protrusion or insertion groove In the case of each of the auxiliary bodies 51B, 52A, 52C, and 53A, the maximum inclination angle θ of the outer circumferential surface with respect to the vertical line may be 45 °.

That is, the insertion protrusion is fixed to the lower end of the vertical line without the width, assuming that the insertion groove is a hemispherical maximum angle that the insertion protrusion can rotate to either side left or right inside the insertion groove, that is, the maximum between the two members The bending angle is 90 °.

Therefore, in order to bend the body provided with the insertion protrusion and the insertion groove by 90 ° with respect to each other, the outer circumferential surfaces of the body provided with the insertion protrusion and the insertion groove respectively should be 45 ° with respect to the vertical line, respectively, when the two outer circumference surfaces are in close contact with each other. The angle is 90 degrees, and if it is larger than this, the rotation angle of the insertion protrusion does not reach 90 degrees due to the body.

However, since the body having the insertion protrusion is not a vertical line having a length but a width, but an entity having a length and a width, the maximum angle at which the insertion protrusion can be rotated is actually less than 90 °, and the angle between the two bodies is The angle of bending is greater than 90 °, so that the maximum inclination angle of the outer peripheral surface of each body provided with the insertion protrusion or the insertion groove is also greater than 45 °.

That is, the maximum inclination angle θ of the body not to interfere with the rotation of the insertion protrusion is 1/2 of the maximum bending angle θ ′ formed by the two bodies rotatably coupled by the insertion protrusion and the insertion groove.

Magnetic play toys of the present invention configured as described above and free of linear deformation can be rotated freely because the insertion protrusion and the insertion groove form a single joint, and thus the rotation of the insertion protrusion and the insertion groove is free of tightness. The insertion protrusion can also be rotated by the insertion groove by itself.

Therefore, as described above, the insertion protrusion is prevented from spontaneously rotating in the insertion groove by the weight of each member, and at the same time, a sound is generated whenever the insertion protrusion is rotated by a certain amount, thereby giving an audible signal effect that the insertion protrusion rotates. In order to protrude and form one stop projection (e) at the lower end of the insertion projection (E), a plurality of projection groove (g) in which the stop projection (e) can be inserted into the inner peripheral surface of the insertion groove (G) at regular intervals. It is preferable to form the array.

Alternatively, a plurality of protrusion grooves may be formed on the outer circumferential surface of the insertion protrusion E and a stop protrusion may be formed on one side of the inner circumferential surface of the insertion groove G.

As the stop protrusion is inserted into the protrusion groove as described above, the rotation of the insertion protrusion is not made unless a predetermined force or more is applied to the insertion protrusion, and the stop protrusion moves from one protrusion groove to another protrusion by rotation. When combined, a click sound will be generated.

In addition, the upper and lower lengths of the auxiliary bodies 51B, 52A, 52C, and 53A of each member provided with the insertion protrusion E and the insertion groove G are determined depending on the size of the insertion protrusion and the insertion groove. The length h of the bodies 51A, 52B, 53B can be freely selected.

However, in order to make the length adjustment more precise, it is desirable to reduce the length h of the main body as much as possible, and in the case of the intermediate connecting member 521, as shown in FIG. It is also possible to omit the intermediate connecting member 522 by only the upper auxiliary body 52A and the lower auxiliary body 52C.

13 is a diagram illustrating a state in which a sculpture is made by using the magnetic play toy of the present invention configured as described above together with a conventional straight magnetic play toy.

In addition, in the magnet play toy of the present invention configured as described above, in some cases, the angle of bending between members may not need to be large, or only length adjustment may be necessary without bending.

Therefore, as shown in FIG. 14, the upper connecting member may be manufactured in a shape 512 in which the insertion protrusion E is directly formed on the lower end of the main body 51A without the lower auxiliary body 51B. The connecting member may also be made into a shape 532 provided with an insertion groove G directly at the upper end of the main body 53B without the upper auxiliary body 53A.

In addition, the intermediate connecting member has a shape 523 provided with an insertion groove G and an insertion protrusion E at the upper and lower ends of the main body 52B, and an insertion groove at the upper and lower ends of the lower auxiliary body 52C. G) and a shape (524) each having an insertion protrusion (E) or a shape (525) each having an insertion groove (G) and an insertion protrusion (E) at the upper and lower ends of the upper auxiliary body (52A). It is also possible.

As described above, the magnetic sticks constituting the magnetic play toy of the present invention can be repeatedly modified in various shapes and at the same time by adjusting the number of intermediate connecting members, the length can be freely adjusted, so that various sculptures that have not been made in the past can be made. Not only can it be made, but there is no need to use many kinds of magnet sticks fixed in various forms as in the prior art, thereby increasing the manufacturing productivity of the magnetic sticks and thus reducing the manufacturing cost.
