Description

Toy block joining structure and toy block comprising the same

The present invention relates to a toy block joining structure and a toy block, and more particularly, to a joining structure for joining a toy block to each other and a toy block including the same.

For early education and creativity development of infants or children, a variety of block toys that can be assembled to form a building or animal structure by assembling a variety of blocks of various shapes have been developed.

Such prefabricated block toys are generally configured so that the unit blocks of various shapes can be directly combined and dismantled by the infant or child. This induces the operator's interest and at the same time makes the child feel a sense of achievement when completing the structure, thereby developing the creativity and intelligence of the infant or child.

Here, in order to assemble and disassemble the toy blocks, a coupling structure for maintaining a constant coupling force in the assembled state of the toy blocks and at the same time forming a constant coupling force between the respective toy blocks should be formed in each toy block.

To this end, a coupling structure for joining the protrusions formed in one toy block and the holes formed in the other toy block is often formed in the toy block. This coupling structure is such that the outer surface of the protrusion and the entire inner surface of the hole are held by the frictional force while the protrusion is inserted into the hole. However, it is often difficult in the manufacturing process to keep the size of the projections and holes formed in the toy block constant. For example, when the toy block is formed of a plastic material, protrusions and holes are frequently formed larger or smaller than a target size due to shrinkage or distortion of the plastic in the molding process of the toy block. When such an error occurs in the manufacturing process, even if the projection is not fitted or inserted into the hole, the bonding force is not maintained, the defect of the product occurs.

In order to reduce the defect of such a product, there is an attempt to maintain the bonding force between the toy blocks by using a magnet provided in or on the surface of the toy block, or to maintain a separate piece respectively bonded to each toy block. In this case, however, the manufacturing cost of the toy block increases and the number of parts (bonding pieces) required for assembling the toy block increases.

Hereinafter, specific embodiments of the present invention will be described with reference to the drawings. However, this is only an example and the present invention is not limited thereto.

In describing the present invention, when it is determined that the detailed description of the known technology related to the present invention may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted. In addition, terms to be described below are terms defined in consideration of functions in the present invention, which may vary according to the intention or custom of a user or an operator. Therefore, the definition should be made based on the contents throughout the specification.

The technical spirit of the present invention is determined by the claims, and the following embodiments are merely means for efficiently explaining the technical spirit of the present invention to those skilled in the art.

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

As illustrated in FIG. 1, the toy block coupling structure 100 according to an embodiment of the present invention relates to a structure for coupling blocks to each other in a toy in which blocks are combined. For example, the present invention relates to a structure in which the coupling protrusions 10 formed in the first block 1 are coupled to each other while being inserted into the coupling holes 20 of the second block 2. Here, the coupling protrusion 10 is coupled to the coupling hole 20 while the coupling protrusion 10 and the coupling hole 20 maintain the coupling state as long as a predetermined force or more does not work, whereby the first block ( 1) and the second block 2 are in a combined state. On the contrary, 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. This repeats the coupling and separation between the blocks (1, 2) and can be made of various types of block (1, 2) assembly. Here, the “predetermined force” may be a force acting on the hand of a person who manipulates the blocks 1, 2, for example, a child or an infant, so that various block 1, 2 combinations can be used as toys. can do.

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

1 and 2, the coupling protrusion 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 Figure 2, the coupling protrusion 10 may be formed in a cylindrical shape, the shape of the coupling protrusion 10 is not limited to this may be formed in the shape of a polygonal pillar, such as square, pentagon, hexagon. Of course. That is, the coupling protrusion 10 may be inserted into the coupling hole 20 of the second block 2 and may be formed in a shape that may be in line contact with the flat portion 30 of the inner surface of the coupling hole 20, which will be described later. The shape can be implemented in various forms.

Meanwhile, a tapered portion T may be formed at an outer circumference of the end of the coupling protrusion 10. Tapered portion (T) is to prevent the end of the engaging projection 10 is sharp, so that the person operating the toy block coupling structure and the toy block according to the embodiment of the present invention is not injured. In addition, when the coupling protrusion 10 is inserted into the coupling hole 20, the initial positioning of the coupling protrusion 10 may be more easily performed at the initial insertion into the coupling hole 20. Here, the tapered portion T may have a curved shape as well as a flat shape.

Hereinafter, referring to FIGS. 3 and 4, the coupling hole 20 for inserting and coupling the above-described coupling protrusion 10 of the first block 1 will be described in detail.

The coupling hole 20 is formed in a shape into which the coupling protrusion 10 can be inserted, and an inner surface thereof includes a flat portion 30 through which the outer circumferential surface of the coupling protrusion 10 of FIGS. 1 and 2 can be in line contact. . For example, the planar portion 30 may include a plane extending in the depth direction of the coupling hole inside the coupling hole, all of the portions that can be coupled with the coupling protrusion 10 in the inner direction of the coupling hole 20. It may be formed in a plane. However, the present invention is not limited thereto, and the planar portion may have a shape in which a plane extending in the depth direction of the coupling hole is coupled in a stepped shape or the like. Hereinafter, the coupling holes 20 according to the embodiment of the present invention will be described in more detail.

The coupling protrusion 10 inserted into the inner space S of the coupling hole 20 including the flat portion 30 is coupled to the coupling hole 20 by contacting the flat portion 30. Here, the outer circumferential surface of the coupling protrusion 10 and the inner surface of the coupling hole 20 are in line contact in the depth direction of the coupling hole 20. Specifically, when the engaging projection 10 is located in the interior (S) of the coupling hole 20, the inner surface of the coupling hole 20 nearest to the center of the coupling hole 20 is the planar portion of the coupling hole 20 30, the coupling protrusion 20 is in contact with the flat portion 30 in a line, and the coupling protrusion 10 and the coupling hole 20 are in contact with each other. As a result, the coupling protrusion 10 may maintain the coupling state unless a predetermined force or more acts in the coupling hole 20 due to the frictional force between the outer circumferential surface of the coupling protrusion 10 and the planar portion 30. Here, the planar portion 30 may be formed along the circumference of the inner surface of the coupling hole 20 in the coupling hole 20, and when forming the inner surface of the coupling hole 20 (for example, injection molding or the like). When formed as) may be formed integrally. In addition, a portion of the inner surface of the coupling hole 20 in which the flat portion 30 is not formed may be an arc portion 40 formed in the shape of an arc. As shown in FIGS. 3 and 4, the planar portion 30 and the arc portion 40 may be alternately formed on the inner surface of the coupling hole 20 according to the embodiment of the present invention.

In addition, the planar portion 30 of the inner surface of the coupling hole 20 may be symmetrically spaced apart by a predetermined angle along the inner circumference of the coupling hole 20. Furthermore, the planar portion 30 may be formed to have the same length in the depth direction of the coupling hole 20. In this manner, when the coupling protrusion 10 is coupled to the coupling hole 20, the coupling force between the coupling protrusion 10 and the coupling hole 20 may act symmetrically, such that the coupling protrusion 10 is coupled to the coupling protrusion 10. The combination of the holes 20 can be made more stable. Here, the predetermined angle is 90 degrees, the flat portion 30 may be formed along the circumference of the inner surface of the coupling hole 20, whereby the coupling protrusion 10 in the interior of the coupling hole 20 is a square pillar shape. It can be combined as is coupled to the hole of.

On the other hand, the flat portion 30 may extend in the depth direction of the coupling hole 20, so that the line contact in the depth direction of the outer peripheral surface of the coupling protrusion 10 and the flat portion 30 can be made sure. have.

As such, by providing the planar portion 30 on the inner surface of the coupling hole 20, the toy block coupling structure 100 according to an embodiment of the present invention is the same sense of assembly of the coupling protrusion 10 and the coupling hole 20. To be secured.

In general, the toy blocks (1, 2) is not only very diverse in shape, but the combination and separation is very frequently made and manipulated, each toy block (1, 2) is formed by a separate mold for each shape Therefore, in many cases, it is difficult to ensure the same feeling of assembly due to molding error for each of the toy blocks 1 and 2. Furthermore, in addition to such a sense of assembly, due to the molding error, the coupling of some of the toy blocks (1, 2) according to the toy blocks (1, 2) is loose and easily detached, or even if the coupling is not good.

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 circumferential portion of the coupling protrusion 10 is in line contact with the plane portion 30. By being able to achieve this, not only the outer peripheral portion of the coupling protrusion 10 can be sufficiently secured to make a line contact, but even if a molding error occurs, the flat portion 30 is stably positioned in a wide portion, A sense of assembling and bonding force can be secured stably and identically.

In addition, when the toy block is formed by injection molding, by providing the flat portion 30 on the inner surface of the coupling hole 20 as in the embodiment of the present invention, it is possible to quickly achieve the correction of the mold and stabilization of the injection molding. have. This will be described in more detail with reference to FIG. 4 as follows. In the following description, a case in which four flat portions 30 are provided along the circumference of the inner surface of the coupling hole 20 will be described. However, the present invention is not limited thereto, and the flat portions 30 are provided in a number of more than four or less than four. The same applies to the case.

In general, in the toy block, in order for the engaging projection to make line contact in the engaging hole, a method of forming a protrusion on the outer peripheral surface of the engaging projection or the inner peripheral surface of the engaging hole can be used.

In this case, when the toy block is manufactured by injection molding into a mold, dimensional error occurs in the protrusion part of the mold, or deformation or distortion easily occurs in the protrusion part in the molding process. In this case, the coupling protrusion and the coupling hole of the toy block may not be stably coupled.

Furthermore, since the coupling protrusion is coupled in line contact with the coupling hole, it is necessary to check and correct the protrusion of the coupling hole in order to determine in which part a problem occurs. However, in the case of the engaging projection or the projection of the engaging hole, especially the projection projecting into the inner part of the engaging hole, there is no proper measuring tool for measuring the size thereof. It is very difficult to be precise.

However, in the toy block coupling structure 100 according to the embodiment of the present invention, a portion of the coupling hole 20 in line contact with the coupling protrusion 10 is formed around the inner surface of the coupling hole 20. By making the flat part 30, such a problem does not arise. That is, as shown in FIG. 4, since the portion of the coupling hole 20 to which the coupling protrusion 10 is coupled is a flat portion 30 having a planar shape, deformation or distortion of the flat portion 30 in the injection molding process may occur. Not only is it hard to occur, even if a diarrhea problem occurs, for example, the distance between the flat portion 30, for example, the distance between 30a and 30c and the distance between 30b and 30d in the mold or coupling hole 20 By measuring easily with a general measuring instrument, it becomes easy to find a problem part. Furthermore, by correcting the portion of the mold corresponding to the flat portion 30, the correction of the problem can be easily made, so that the correction of the mold and the stabilization of the injection molding can be easily and quickly achieved.

In addition to this, the hole portion 35 (the hole portion formed adjacent to the opposite surface of the

plane portions

30a, 30b, 30c, and 30d in FIG. 4) may be formed on the opposite side of the plane portion 30. The hole part 35 may be formed on the opposite side of the plane of the planar part 30 and may be formed in the longitudinal direction of the coupling hole 20. The hole portion 35 is partially deformed to the flat portion 30 by the pressing of the coupling protrusion 10 when the coupling protrusion 10 is inserted into the coupling hole 20 to make line contact with the flat portion 30. Even if there is a buffer and at the same time it can ensure a stable coupling of the coupling projection 10 and the coupling hole (20). For example, when the toy blocks 1 and 2 according to the embodiment of the present invention are formed of plastic, when the coupling protrusion 10 is inserted into the coupling hole 20, the flat portion 30 is minutely holed. While bending inwardly, the coupling protrusion 10 may be stably coupled.

On the other hand, in the toy block coupling structure 100 according to an embodiment of the present invention, the guide portion 50 may be formed at the end of the coupling hole 20. The guide part 50 extends by a predetermined length from the outer end of the coupling hole 20 in the depth direction of the coupling hole 20, and may be formed over the entire outer circumference of the coupling hole 20. The planar portion 30 of the coupling hole 20 may be formed from an end portion of the guide portion 50 in the depth direction, and may be spaced apart from the outer end of the coupling hole 20 in the depth direction of the coupling hole 20.

Here, when both the guide part 50 and the coupling protrusion 10 are 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. In addition, the outer peripheral portion of the coupling protrusion 10 is formed to be smaller than or equal to the minimum inner diameter in the radial direction of the inner circumferential surface of the coupling hole 20 formed by the planar portion 30, that is, the outer diameter of the coupling protrusion 10. It has an inner diameter larger than the inner diameter which the flat part 30 which comes into contact forms. Furthermore, the inner diameter of the guide part 50 may decrease from the outer end of the coupling hole 20 toward the depth direction of the coupling hole 20. Here, the inner diameter of the guide part 50 may 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 with a radius of 0.2 mm to 0.3 mm.

The guide portion 50 serves to guide the coupling protrusion 10 into the coupling hole 20 when the coupling protrusion 10 enters the coupling hole 20 to be inserted into the coupling hole 20. ) Can be coupled to the coupling protrusion 10 to the coupling hole 20 more easily. Furthermore, when the coupling protrusion 10 enters into the coupling hole 20, the initial entry resistance in the coupling hole 20 of the coupling protrusion 10 may be alleviated.

In addition, a tapered portion may be provided so as to taper around the end of the coupling hole 20 side of the coupling protrusion 10 (for example, to taper 0.2 mm inward in a 0.5 mm section in the longitudinal direction at the end of the coupling protrusion 10). have. As a result, the initial entry resistance of the coupling protrusion 10 into the coupling hole 20 may be further relaxed.

That is, although different depending on the shape and size of the coupling protrusion 10 and the coupling hole 20, for example, when the coupling protrusion 10 enters into the coupling hole 20, the coupling protrusion 10 The initial entry resistance is smallest when the entry direction and the central axis direction of the coupling hole 20 form a predetermined angle (for example, 21.8 degrees). At this time, by providing a taper portion in the coupling protrusion 10 and the guide portion 50 in the coupling hole 20, the coupling protrusion 10 can be easily positioned at the end of the coupling hole 20. In this way, the force applied to the engaging projection 10 by the operator can be applied in the forward direction.

Next, for example, as shown in Figure 5 (a) to 5 (s), the toy block coupling structure 100 according to an embodiment of the present invention is a variety of toys that the outer surface is formed by the combination of the curved surface and plane It may be formed in the block 200. That is, one or more of the coupling protrusion 10 and the coupling hole 20 of the toy block coupling structure 100 may be formed on the outer surface of the toy block 200 to enable various couplings between the toy blocks 200. . Through such various couplings, structures of various shapes can be made in a state where the coupling between the toy blocks 200 is stably maintained.

On the other hand, the coupling protrusion 10 and the coupling hole 20 of the toy block coupling structure 100 is formed on one surface of the outer surface of one toy block 200, the coupling hole 20 of the other toy block 200 And it can be combined with each of the coupling projections 10, of course. Thus, the structure through the coupling of the toy block 200 can be made into a more various shape.

Although the present invention has been described in detail with reference to exemplary embodiments above, those skilled in the art to which the present invention pertains can make various modifications to the above-described embodiments without departing from the scope of the present invention. I will understand.
