In addition, in order not to obscure the subject matter of the present invention, a part overlapping with the description in the related art or a fact apparent to those skilled in the art will be briefly described or omitted.

1 is an exploded perspective view illustrating a state in which two assembly pieces 30 constituting the assembled toy component according to the first embodiment of the present invention are first fastened by the first pin 10 among the fastening pins. to be.

According to a first preferred embodiment of the present invention, the assembly piece 30 included in the prefabricated toy component of the present invention may be formed in the form of a three-dimensional figure block having a predetermined thickness in the longitudinal direction of the fastening hole 35 as shown. Can be.

Furthermore, the block-shaped assembly 30 may be formed in the form of a three-dimensional figure of a structure in which a cube unit forming one unit is extended as shown, firstly, the advantages of such a structure are first, face centers facing each other in one unit. Since the fastening holes 35 formed to penetrate each other may have a standardized structure for each unit, expansion and applicability are increased. Second, as shown in three directions of 90 ° angles, which form an axis of three-dimensional coordinates. This is because it is easy to form the fastening hole 35, which enables the assembly 30 to be mutually coupled in the maximum six directions.

In addition, the fastening holes 35 are provided with engaging jaws at the inlet to make a fastening fixed state by abutting the brace jaw of the fastening pin as in the conventional example described above.

In the first embodiment, the locking step is divided into an outer locking step 31 and an inner locking step 32. In FIG. 1, only the outer locking step 31 can be confirmed, and a detailed description thereof will be described later. do.

On the other hand, in order to perform the fastening function, the locking jaws including the outer locking jaw 31 should have a wall structure that is not parallel to the insertion direction of the fastening pin, in the case of the outer locking jaw 31 according to the first embodiment, As shown in the figure, it can be seen that the inner diameter is narrowed toward the inner side.

Unlike the conventional fastening pin 100 described with reference to FIG. 11, the fastening pin 100 according to the present invention is directly inserted into the fastening hole 35, the first pin 10 shown in FIG. 2, the second pin is inserted into the first pin 10.

That is, by having a structure in which the second pin 20 is inserted into the first pin 10, it is possible to secure a 'dramatically improved fastening state stability' which is the most basic object of the present invention. The description will be described later in detail with reference to FIGS. 4 to 7.

1 illustrates a structure and a mounting method of the first pin 10 among the components of the fastening pin 100.

The first pin has a hollow 15 penetrating the front end-rear end in the insertion direction to have a shape of a pipe as a whole, and a brace corresponding to the locking step of the assembly piece 30 such as the outer locking step 31 ( 13) at both ends.

In the case of the brace 13 shown, it is a structure protruding in an annular shape with a slope formed to engage the slope-shaped outer locking jaw 31 of the assembly piece 30, the diameter of which is fastening of the portion where the locking jaw is formed. Of course, it should be formed larger than the inner diameter of the ball (35).

Meanwhile, as shown in the drawing, the cutting groove 11 extending from one end of the first pin 10 is provided, so that when the first pin 10 is pushed into the fastening hole 35 in the form of an interference fit, the cutting is performed. The gap formed by the groove 11 is narrowed and the overall diameter is reduced to be able to pass through the interior of the fastening hole 35. The structure of the illustrated slope also serves to help such work more smoothly.

FIG. 2 shows the hollow 15 of the first pin 10 in a state in which the first pin 10 shown in FIG. 1 is completely inserted through two assembly pieces 30 to form a primary fastening state. 2 is a perspective view showing a state in which the second pin 20 is fitted.

The first fastening state in which only the first pin 10 is fastened does not provide a better state than the fastening state using the conventional fastening pins described with reference to FIG. 11.

Rather, in the illustrated first embodiment, since the angle of the contact surface of the engaging jaw and the support jaw forms a slope that is gentler than the right angle to the travel direction of the fastening pin, the possibility of departure may be higher.

However, in the first fastening state, by inserting the second pin filling the inner surface of the hollow 15 of the first pin, the function of the end elastic contraction by the cutting groove 11 is prevented to ensure an extremely improved fastening state This is possible, which will be described later.

On the other hand, in the case of the second pin inserted into the hollow 15 of the first pin 10, unlike the first pin 10, the structure limitation such as the through-hole should be formed, but the elasticity is preferably not It is desirable to be made of less material.

Further, in order to secure a stable insertion state, by forming the male screw thread 21 on the outer circumferential surface as shown, the female screw thread 16 and the screw coupling applied to the inner surface of the hollow 15 of the first pin 10 are applied. It may be configured to.

At this time, the fastening tool corresponding end 25, such as the hexagonal groove corresponding to the hexagon wrench, as shown in order to apply a fastening tool such as a screwdriver, a spanner, a hexagon wrench, and the like, for easier engagement and release, It is preferably formed.

3 is a view showing a state in which the fastening between the assembly pieces 30 using the fastening pin 100 of the assembly toy component according to the first embodiment is completed, it can be confirmed that a stable fastening can be secured through this. .

In the above, the specific structure of each constituent means of the first embodiment has been described with reference to Figs. 1 to 3, and with reference to Figs. 4 to 7, below, the process of fastening made through the above-described structure, Through the following will be described in more detail.

4 to 7 are cross-sectional views of the above-described components of the first embodiment in a front direction, and FIG. 4 shows a first pin into two assembly pieces 30 overlapping each fastening hole 35 to form a straight line. It is sectional drawing which shows the state in which 10 starts inserting.

As shown, although the diameter of the portion of the brace 13 formed in the insertion tip of the first pin 10 shown is larger than the diameter of the inlet 35, the function of the above-described cutting groove 11 This makes it possible to pass through the pressure by force.

On the other hand, through Figure 4, inside the assembly piece 30 fastening hole 35, there is formed an internal locking jaw 32, which is another type of locking jaw that was not identified through FIGS. You can check it.

The inner locking jaw 32 has slopes in opposite directions of the adjacent outer locking jaw 31, respectively, and may be formed in symmetrical shapes up and down at both inlets of the fastening hole 35, which are fastening pins 100. As a part of contributing to the structural change and diversification state of the, the synergistic effect thereof will be clearly shown through the description with reference to FIGS. 8 to 9 showing the second embodiment.

The first pin 10 inserted in the interference fit manner is seated in the fastening hole 35 in the state shown in FIG.

1 and 4, the blocking jaw 17 protrudes from the outer circumferential surface of the length center of the first pin 10, and the blocking jaw 17 is in close contact with the two assembled pieces 30 fastened to each other. By forming a structure interposed between each outer engaging jaw 31 adjacent to the surface, it serves to easily limit the fastening depth.

On the other hand, the distance between the two braces 13 formed on both ends of the first pin 10 is close to each other by the length between any two latching jaw formed on the two assembled pieces 30 fastened In order to maintain the state tightly, the first exemplary embodiment is set to correspond to the length between the outermost latching jaw 31 and the outermost latching jaw 31 of the longest distance, but is not limited thereto. For example, it may be adjusted to have a length between the inner locking jaw 32 of the one assembly piece 30 and the outer locking jaw 31 of the other assembly piece (30).

As such, the second pin 20 is inserted into the hollow of the first pin 15 in the first fastening state in which the first pin 10 is seated, so that the second pin ( 20) can completely block the contraction of the end of the first pin (10), thereby ensuring a secure fastening state.

At this time, the first pin 10 and the second pin 20, by forming the threads (16, 21) to be engaged with each other on the inner surface and the outer peripheral surface of the hollow 15, it is possible to achieve a more stable coupling of the screw method. .

On the other hand, such screw coupling may also provide a useful function even when the fastening state is released. If the screw coupling method is not applied, it is very difficult to separate the second pin 20 deeply coupled to the first pin 10 from the first pin 10, but as shown in FIG. When the second pin 20 is turned in the release direction of the screw coupling by applying a hexagon wrench or the like to the fastening tool corresponding end 25 of the second pin 20, the first pin 10 is easily protruded by the head part. It is easy to remove the second pin 20 from the.

8 to 9 are views illustrating the assembled toy component according to the second preferred embodiment of the present invention.

8 is a perspective view showing the assembled toy component according to the second embodiment, wherein the basic structure of the assembled pieces 30 is the same as in the first embodiment.

On the other hand, the fastening pin consisting of the first pin 10 and the second pin 20 can be seen that the length is relatively short.

That is, as briefly mentioned above, the distance between the brace 13 of the fastening pin according to the present invention, the position, the number of the latching jaw (31, 32) formed in the fastening hole 35 of the assembly piece 30 It may be arbitrarily selected according to, etc., in the case of having a fastening hole 35 structure as in the embodiment illustrated through the cross-sectional view of FIGS. 4 to 7, 9, the close contact surface of the two assembly pieces 30 to be fastened In the configuration that allows the first pin 10 and the second pin 20 to be mounted between the two closest inner engaging jaw (32).

In this case, the entirety of the first pin 10, that is, the insertion tip of the first pin 10 as well as the rear end positioned opposite to the insertion direction, pass through the locking jaws 31 and 32 of the inlet of the fastening hole 35. In order to be able to do so, it is preferable that the cutting groove 11 is formed to extend from both ends, not one as shown.

On the other hand, since the structure, coupling method, etc. of the second pin 20 are not significantly different from those in the above-described first embodiment, redundant description thereof will be omitted.

9 is a cross-sectional view of the second embodiment will be described in more detail the manner in which the assembly pieces 30 of the assembled toy component having the above-described configuration is fastened.

As shown, the fastening pin 100 composed of the first pin 10 and the second pin 20 has a compact structure between the adjacent inner locking jaw 32 of the two assembly pieces 30 in a fastened state. Is mounted.

Accordingly, unlike the fastening pin 100 illustrated in the second embodiment, unlike the structure in which the fastening operation 35 can not be performed by using the fastening hole 35 in the first embodiment, the fastening operation is performed once. In the case of using, the locking jaws 31 and 32 opposite to the locking jaws 31 and 32 used for the fastening in one fastening hole 35 are still available.

Therefore, as shown in the upper part of the two assembly pieces 30 fastened to share the fastening hole 35 already used for fastening, so that one assembly piece 30 can be additionally mounted to perform additional fastening work. In theory, this operation is infinitely repeatable as long as the fastening pin 100 having the same structure is used.

That is, when configuring the fastening pin 100 or the like in the structure shown in the second embodiment, the number and fastening structure of the assembly piece 30 that can be fastened in one structure can be extremely up and diversified.

FIG. 10 is a diagram illustrating a modification of the first and second embodiments illustrated in FIGS. 1 to 9 and illustrates a configuration for adding additional functions.

In the case of the fastening structure of the assembly piece 30 using the fastening pin, as described above, there is an advantageous side to secure the movement in the connection part, such as the configuration of the rotary connection.

However, in certain situations, such as when the fastening angle of the assembly piece 30 must be stably maintained at a certain angle, such a structure may be rather disadvantageous.

At this time, in order to prevent the relative rotational movement between the plurality of assembly pieces 30 via the fastening pin 100, unlike the structure shown, to form a fastening pin in the form of a rotationally asymmetrical pillar like a polygonal column rather than a cylinder You may also consider the structure.

On the other hand, as shown in Figures 1 to 8 by utilizing the structure of the cutting groove 11 formed in the past to the first pin 10 may be considered a structure to give the above-described anti-rotation function, such as in Figure 10 As in the case of the assembly 30 shown, by providing the anti-rotation tab 38 protruding from the outer engaging jaw 31 of the fastening hole 35, the gap of the cutting groove 11 of the first pin (10). When the anti-rotation tab 38 is interposed, and the crimping of the end of the first pin 10 is prevented by the second pin 20 in this state, the fastening pin 100 including the first pin 10 is included. Relative rotation of can be limited.

As described above, the present invention has been described with reference to the preferred embodiments and drawings, but the present invention is not limited to the configuration and operation according to the illustrated and described embodiments. Rather, those skilled in the art will appreciate that many modifications and variations of the present invention are possible without departing from the spirit and scope of the appended claims. Accordingly, all such suitable changes and modifications and equivalents should be considered to be within the scope of the present invention.
