Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a toy block coupling structure,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a toy block coupling structure and a toy block, and more particularly, to a coupling structure for coupling toy blocks together and a toy block including the same.

In order to develop early education and creativity of infants or children, various block toys have been developed which can construct structures of buildings or animals in various shapes by assembling blocks.

Such a prefabricated block toy is generally constructed so that infant or child can directly combine and disassemble unit blocks of various shapes. Thus, the creativity and intelligence of the infant or the child are developed by causing the interest of the operator and at the same time, feeling the sense of accomplishment when the structure is completed.

Here, in order to assemble and disassemble the toy blocks, a coupling structure is formed in each toy block so as to maintain a constant coupling force in the assembled state of the toy blocks and to form a constant coupling force between the toy blocks.

To this end, in many cases, the toy block is formed with a coupling structure for coupling the protrusion formed on one toy block and the hole formed on another toy block. In such a coupling structure, the outer surface of the projection and the entire inner surface of the hole are held by the frictional force while the projection is inserted into the hole. However, it is often difficult to keep the sizes of the projections and holes formed in the toy block constant in the manufacturing process. For example, when the toy block is formed of a plastic material, the protrusion and the hole may be formed to be larger or smaller than a target size due to shrinkage or distortion of the plastic during the molding process of the toy block. If such an error occurs in the manufacturing process, the protrusion will not fit in the hole or the fitting force will not be maintained even if the protrusion is fitted, resulting in defective product.

In order to reduce the defects of such products, there is an attempt to maintain the bonding force between the toy blocks by using a magnet provided in the surface of the toy block or on the surface thereof, or to maintain them as separate pieces respectively coupled to the respective toy blocks. However, in this case, the manufacturing cost of the toy block is increased and the number of parts (joining piece) necessary for assembling the toy block is increased.

In the following description, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear. The following terms are defined in consideration of the functions of the present invention, and may be changed according to the intention or custom of the user, the operator, and the like. Therefore, the definition should be based on the contents throughout this specification.

The technical idea of the present invention is determined by the claims, and the following embodiments are merely a means for effectively explaining the technical idea of the present invention to a person having ordinary skill in the art to which the present invention belongs.

FIG. 1 is a cross-sectional front view of an embodiment of a toy block coupling structure 100 according to an embodiment of the present invention, and FIG. 2 is a perspective view of a toy block coupling structure 100 according to an embodiment of the present invention.

As shown in FIG. 1, a toy block coupling structure 100 according to an embodiment of the present invention relates to a structure for coupling blocks together in a toy in a manner of joining the blocks. For example, the present invention relates to a structure in which the engaging projections 10 formed in the first block 1 are inserted into the engaging holes 20 of the second block 2 and engaged with each other. Here, the coupling protrusion 10 and the coupling hole 20 are maintained in a coupled state when the coupling protrusion 10 is fitted to the coupling hole 20 and no force acts on the coupling protrusion 10, 1) and the second block 2 are in a combined state. Conversely, when a predetermined force or more acts to separate the first block 1 and the second block 2, the first block 1 and the second block 2 can be separated. In this way, the coupling and separation between the blocks 1 and 2 can be repeated to form various types of block (1, 2) assemblies. Here, the " predetermined force " may be a force that can act in the hands of a person manipulating the block 1, 2, e.g., a child or infant, thereby allowing the various block 1, 2 assemblies to be used as a toy can do.

Meanwhile, the first block 1 and the second block 2 may be formed of plastic, for example, ABS (Acrylonitrile Butadiene Styrene).

1 and 2, the engaging projection 10 may have a shape protruding from one side of the first block 1, and may include a hollow portion H therein. As shown in FIG. 2, the coupling protrusions 10 may be formed in a cylindrical shape, and the shape of the coupling protrusions 10 is not limited thereto, but may be a polygonal column shape such as a square, a pentagon, a hexagon, or the like. Of course. That is, the engaging projection 10 may be formed in a shape that is fitted in the engaging hole 20 of the second block 2 and can be in line contact with the flat portion 30 of the inner surface of the engaging hole 20 described later, The shape can be implemented in various forms.

On the other hand, a tapered portion T may be formed on the outer periphery of the end of the engaging projection 10. The tapered portion T makes the end of the engaging projection 10 not to be sharp so that the toy block coupling structure according to the embodiment of the present invention and the person who operates the toy block can be prevented from being injured. In addition, when the engaging projection 10 is inserted into the engaging hole 20, the initial positioning of the engaging projection 10 can be facilitated at the initial stage of insertion into the engaging hole 20. Here, the taper portion T may have a shape of a curved surface as well as a shape of a flat surface.

Hereinafter, with reference to Figs. 3 and 4, the engaging hole 20 for engaging with the engaging projection 10 of the first block 1 will be described in detail.

The engaging hole 20 is formed in such a shape that the engaging projection 10 can be inserted therein and the inner surface thereof includes a flat surface portion 30 in which the outer circumferential surface of the engaging projection (10 in Figs. 1 and 2) .

The engaging projection 10 inserted into the inner space S of the engaging hole 20 including the flat surface portion 30 is engaged with the engaging hole 20 by contacting the flat surface portion 30. Here, the outer circumferential surface of the engaging projection 10 and the inner surface of the engaging hole 20 are in line contact with each other in the depth direction of the engaging hole 20. The inner surface of the engaging hole 20 closest to the center of the engaging hole 20 is located on the flat surface of the engaging hole 20 when the engaging projection 10 is positioned in the inner portion S of the engaging hole 20. [ The engaging projection 10 and the engaging hole 20 are brought into contact with each other while the engaging projection 20 is in contact with the flat surface portion 30 by a line. As a result, the coupling protrusion 10 can be maintained in the coupled state as long as a predetermined force or more does not act in the coupling hole 20 due to the frictional force between the outer circumferential surface of the coupling protrusion 10 and the flat surface portion 30. Here, the flat portion 30 may be formed along the inner circumference of the coupling hole 20 in the coupling hole 20, and may be formed when the inner surface of the coupling hole 20 is formed (for example, As shown in Fig. The portion of the inner surface of the coupling hole 20 where the flat portion 30 is not formed may be an arcuate portion 40 formed in the shape of an arc. 3 and 4, the planar portion 30 and the arcuate portion 40 may be alternately formed on the inner surface of the coupling hole 20 according to the embodiment of the present invention.

The flat portion 30 of the inner surface of the coupling hole 20 may be formed symmetrically with a predetermined angle around the inner surface of the coupling hole 20. Further, the flat portion 30 may be formed to have the same length in the depth direction of the coupling hole 20. [ The engagement between the engaging projection 10 and the engaging hole 20 can symmetrically act when the engaging projection 10 is engaged with the engaging hole 20, The coupling of the holes 20 can be made more stably. Four flat portions 30 may be formed around the inner surface of the coupling hole 20 so that the coupling protrusions 10 are formed in a square pillar shape in the coupling hole 20 As shown in FIG.

The plane portion 30 may extend in the depth direction of the coupling hole 20 so that the line contact with the outer peripheral surface of the coupling projection 10 in the depth direction of the plane portion 30 can be performed reliably have.

As described above, by providing the flat surface portion 30 on the inner surface of the coupling hole 20, the toy block coupling structure 100 according to the embodiment of the present invention has the same assembling feeling of the coupling projection 10 and the coupling hole 20 .

In general, the shape of the toy blocks 1 and 2 is very various, and their joining and separation are very frequently performed and operated. Each toy block 1 and 2 is molded into a separate mold for each shape of the toy blocks 1 and 2 So that it is often difficult to ensure the same sense of assembly with the molding error of each toy block 1, 2. Furthermore, not only the sense of assembly but also the molding error may cause the detachment of some toy blocks 1 and 2 due to loosening of the toy blocks 1 and 2, which may occur easily or not easily.

However, in the toy block coupling structure 100 according to the embodiment of the present invention, the planar portion 30 is provided on the inner surface of the coupling hole 20 and the outer peripheral portion of the coupling projection 10 is in line contact with the planar portion 30 Not only a portion where the outer circumferential portion of the engaging projection 10 can make line contact can be sufficiently secured but also the flat portion 30 is stably positioned in a wide portion even if a molding error occurs, The assembly feeling and the coupling force can be stably and equally secured.

In addition, when the toy block is formed by injection molding, the plane portion 30 is provided on the inner surface of the coupling hole 20 as in the embodiment of the present invention, so that it is possible to rapidly correct the mold and stabilize the injection molding have. In the following, referring to FIG. 4, a more detailed description will be given. In the following description, four planar portions 30 are provided along the inner circumference of the coupling hole 20. However, the present invention is not limited to this, and the planar portions 30 may be provided in a number greater than four or less than four The present invention is applicable to the same case.

Generally, in the toy block, a method of forming protrusions on the outer circumferential surface of the engaging projection or on the inner circumferential surface of the engaging hole may be used in order to make the engaging projection in line contact in the engaging hole.

In this case, if the toy block is manufactured by a method of injection molding into a mold, dimensional errors may occur in the protruding portion of the mold or distortion or distortion may occur in the protruding portion in the molding process. In this case, the engaging projections of the toy block and the engaging holes may not be stably engaged.

Further, since the engaging projections are connected to the engaging holes in line contact with each other, it is necessary to check and correct the protrusions of the engaging holes in order to determine which portion is troubled. However, in the case of protrusions of the engaging projections or engaging holes, particularly protrusions protruding inward of the engaging holes, it is difficult to find a problematic part because there is no proper measuring tool for measuring the dimensions and the like, It is very difficult to be precise.

However, in the case of the toy block coupling structure 100 according to the embodiment of the present invention, the portion of the coupling hole 20 which is in line contact with the coupling projection 10 is formed around the inner surface of the coupling hole 20 By providing the flat portion 30, such a problem does not occur. 4, since the portion of the coupling hole 20 to which the coupling protrusion 10 is coupled is the planar portion 30 having a planar shape, deformation or distortion of the planar portion 30 during the injection molding process The distance between the planar portions 30, for example, the distance between 30a and 30c in Fig. 4, and the distance between 30b and 30d, in the mold or engagement hole 20 By easily measuring with a general instrument, it becomes easy to find the problematic part. Further, by correcting the portion of the mold corresponding to the flat surface portion 30, the problem can be easily corrected and the mold can be easily corrected and the injection molding can be stabilized easily and quickly.

In addition, a hole portion (a hole portion formed adjacent to the opposite surface of the planar portions 30a, 30b, 30c, and 30d in FIG. 4) may be formed on the opposite side of the planar portion 30. Such a hole portion may be deformed even if the flat portion 30 is partially deformed by the pressing of the engaging projection 10 when the engaging projection 10 is inserted into the engaging hole 20 to make a line contact with the flat portion 30 It is possible to ensure stable bonding of the coupling protrusion 10 and the coupling hole 20 at the same time as buffering. For example, when the toy blocks 1 and 2 according to the embodiment of the present invention are formed of plastic, when the engaging projection 10 is inserted into the engaging hole 20, So that the coupling projection 10 can be stably engaged.

Meanwhile, in the toy block coupling structure 100 according to the embodiment of the present invention, the guide portion 50 may be formed at the end of the coupling hole 20. [ The guide portion 50 may be formed to extend from the outer end of the coupling hole 20 to the inner side in the depth direction of the coupling hole 20 by a predetermined length and may extend over the entire outer edge of the coupling hole 20. The flat portion 30 of the coupling hole 20 may be formed from the depth direction end portion of the guide portion 50 and may be formed to be spaced from the outer end of the coupling hole 20 in the depth direction of the coupling hole 20.

Here, when the guide portion 50 and the coupling protrusion 10 are all formed in a cylindrical shape, the guide portion 50 may have an inner diameter larger than the outer diameter of the coupling protrusion 10 inserted into the coupling hole 20. The inner diameter of the coupling hole 20 formed by the flat surface portion 30 is equal to or smaller than the outer diameter of the coupling projection 10 so that the outer peripheral portion of the coupling projection 10 is smaller than the outer diameter of the coupling projection 10, And has an inner diameter larger than an inner diameter formed by the flat surface portion 30 to be brought into contact therewith. Further, the inner diameter of the guide portion 50 can be reduced from the outer end of the coupling hole 20 to the inner side in the depth direction of the coupling hole 20. Here, the inner diameter of the guide portion 50 can be linearly reduced. However, the present invention is not limited thereto, and may be reduced while forming a concave curve. For example, the concave curve may be formed by rounding a radius of 0.2 to 0.3 mm.

The guide portion 50 serves to guide the engaging projection 10 into the engaging hole 20 when the engaging projection 10 is inserted to be inserted into the engaging hole 20, It is possible to more easily engage the engaging projection 10 with the engaging hole 20. Further, when the engaging projection 10 enters to enter the engaging hole 20, the initial engaging resistance in the engaging hole 20 of the engaging projection 10 can be relaxed.

It is also possible to provide a tapered portion so as to taper around the end of the engaging projection 10 on the side of the engaging hole 20 (for example, tapering 0.2 mm inward in the longitudinal 0.5 mm section to the end of the engaging projection 10) have. This can further alleviate the initial entry resistance of the engaging projection 10 into the engaging hole 20.

For example, when the engaging projection 10 enters the engaging hole 20, the engaging protrusion 10 and the engaging hole 20 may be formed in the same direction, When the entering direction and the central axis direction of the coupling hole 20 form a predetermined angle (for example, 21.8 degrees), the initial entry resistance is the smallest. At this time, by providing the tapered portion in the coupling projection 10 and providing the guide portion 50 in the coupling hole 20, the coupling projection 10 can easily be initialized at the end of the coupling hole 20 So that the force applied to the engaging projection 10 by the operator can be applied in the forward direction.

Next, for example, as shown in Figs. 5 (a) to 5 (s), the toy block coupling structure 100 according to the embodiment of the present invention includes various toy May be formed in the block 200. That is, at least one of the engaging projections 10 and the engaging holes 20 of the toy block engaging structure 100 may be formed on the outer surface of the toy block 200 to allow various combinations between the toy blocks 200 . Through various combinations, the structures of various shapes can be made in a state where the coupling between the toy blocks 200 is stably maintained.

On one side of the outer surface of one toy block 200, the engaging projections 10 and the engaging holes 20 of the toy block engaging structure 100 are all formed so that the engaging holes 20 of the other toy blocks 200 And the engaging projection 10, respectively. Thereby, the structure through the engagement of the toy blocks 200 can be made into various shapes.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is clearly understood that the same is by way of illustration and example only and is not to be taken by way of limitation, I will understand.
