1 is a perspective view showing a fixing unit of a coupling unit for a toy according to an embodiment of the present invention. FIG. 2A is a perspective view illustrating the fixing unit of FIG. 1 , and FIG. 2B is a cross-sectional view illustrating the fixing unit of FIG. 1 .

1 to 2b, the toy coupling unit (8, see FIG. 5) according to this embodiment includes a fixing unit (1) and a plate part (200, see FIG. 5), the fixing unit (1) ) is inserted into the plate part 200, and a plurality of overlapping plate parts are fixed to each other.

In this case, the plate part 200 will be described later with reference to FIG. 5 , and only the fixing unit 1 will be described below.

That is, the fixing unit (1) is inserted into the plate part (200) and positioned, specifically, it includes an insertion unit (2) and a cover unit (3).

1 shows a state in which the insertion unit 2 and the cover unit 3 are separated from each other, but this is merely separated from each other for convenience in explaining the structure and shape, and the fixing unit ( In 1), the insertion unit 2 is inserted into the inside of the cover unit 3, and it is characterized in that it moves only within a predetermined stroke range.

More specifically, the insertion unit 2 includes a head portion 10 , a support portion 20 , and an insertion portion 30 .

The head part 10 forms an upper surface of the insertion unit 2, has a circular plate shape, and may have a predetermined thickness. In this case, since the opening of the plate part 200 to be described later has a cylindrical shape, the head part 10 has a circular plate shape, and may be variously changed according to the shape of the opening part.

However, hereinafter, for convenience of description, it will be described that the opening has a cylindrical shape.

The head portion 10 has a predetermined thickness, and when combined with the plate portion 200 to be described later, protrudes from the upper portion of the plate portion 200 and is positioned.

The support part 20 is formed on the bottom surface 11 of the head part 10, has a diameter smaller than the diameter of the head part 10, and may have a circular plate shape having a predetermined thickness.

In this case, the thickness of the support part 20 may be formed to be substantially the same as the thickness of the head part 10 , and otherwise may be variously changed.

Like the head part 10 , the support part 20 protrudes above the plate part 200 when combined with the plate part 200 .

In addition, when the plate parts 200 are fixed, the bottom surface 21 of the support part 20 comes into contact with the upper surface of the upper cover 50 of the cover unit 3 .

The insertion part 30 extends downward from the bottom surface 21 of the support part 20 and includes an insertion body 31 , an upper part 32 , a lower part 33 , and a protrusion part 35 .

The upper portion 32 is a portion in contact with the bottom surface 21 of the support portion 20 , and the lower portion 33 forms an end of the insertion portion 30 .

In this case, the lower part 33 is not opened and closed, and the insertion body 31 extends in one direction between the upper part 32 and the lower part 33 .

The insertion body 31 may have, for example, a rectangular block shape, and a groove portion 34 extending as much as the length of the insertion body 31 is formed in the center of the insertion body 31 .

In this case, the insertion body 31 is inserted into the cover unit 3, and the groove portion 34 formed in the insertion body 31 has a fixing protrusion of the cover unit 3 to be described later. (65) is located.

Thus, when the insertion body 31 moves in the vertical direction, the fixing protrusion 65 is also located in the groove portion 34 in the vertical direction relative to the groove portion 34 .

In particular, since the lower end of the insertion body 31 is blocked by the lower portion 33, the fixing protrusion 65 positioned on the groove portion 34 cannot be positioned outside the lower portion 33, Accordingly, the position of the fixing protrusion 65 relatively positioned on the groove part 34 may be limited.

The protrusion 35 is formed to protrude above the insertion body 31 , that is, at a position adjacent to the upper portion 32 , and protrudes from the surface where the groove portion 34 is not formed on the insertion body 31 . can be

The protrusion 35 is positioned to be inserted into the fixing groove 66 of the cover unit 3, which will be described later, so that the position of the insertion unit 2 can be fixed on the cover unit 3 through this. there is.

The cover unit 3 includes an upper cover 50 and a cover portion 60 .

The upper cover 50 forms the upper part of the cover unit 3, has a larger outer diameter than the cover part 60, and is fixed on the opening of the plate part 200 to be described later. .

In addition, on the upper surface of the upper cover 50, the bottom surface 21 of the support part 20 is positioned, and in this way, the bottom surface 21 of the support part 20 is in contact with the upper cover 50. In this state, the fixing unit 1 fixes the plate parts.

On the other hand, when the support part 20 is spaced apart from the upper cover 50 and positioned upward, the fixing unit 1 releases the fixing of the plate parts.

The cover portion 60 extends downwardly from the bottom surface 51 of the upper cover 50, and includes an upper extension 61, a branch extension 62, a lower extension 63, and a fixing protrusion ( 65).

The upper extension portion 61 extends from the bottom surface 51 of the upper cover 50, and the branch extension portion 62 further extends from the upper extension portion 61, as shown in FIG. It is characterized in that a pair of branches that are separated from each other are extended together.

In this embodiment, since the length of the cover part 60 is relatively short, the length of the upper extension part 61 is short, and the branch extension part 62 is the bottom surface 51 of the upper cover 50 . However, the length of the upper extension portion 61 may be variously designed in consideration of the overall length of the cover portion 60 .

In addition, as a pair of the branch extension parts 62 extend in the lower direction while being spaced apart from each other, as shown in FIG. 1 , the upper extension part 61 and the branch extension part 62 are generally 'U'-shaped. It can be extended to have a shape.

In addition, a cover space 64 is formed inside the branch extension part 62 , and the insertion body 31 of the insertion unit 2 is positioned in the cover space 64 .

That is, the cover unit 3 is fixed to the upper side of the opening 220 as the upper cover 50 has a relatively larger outer diameter than the upper extension 61 and the branch extension 62 . As the lower extension part 63 has a relatively larger outer diameter than the upper extension part 61 and the branch extension part 62, it is fixedly positioned below the opening 220. .

Thus, the cover unit 3 is fixedly positioned on the opening of the plate part 200 .

On the other hand, in this embodiment, a fixing groove 66 is formed between the upper extension part 61 and the branch extension part 62, that is, in a portion connected to each other, and the fixing groove 66 is shown in FIG. 2B. As shown, the protrusion 35 formed on the insertion body 31 is positioned.

In addition, the fixing protrusion 65 protrudes toward the cover space 64 on the inner surface of the branch extension part 62 , and the fixing protrusion 65 is, as described above, of the insertion body 31 . On the groove portion 34 , it is positioned relative to the groove portion 34 .

In the fixing unit 1 having the above structure, the relative movement between the insertion unit 2 and the cover unit 3 will be described with reference to FIGS. 2A and 2B .

First, the insertion unit 2 maintains a state coupled to the cover unit 3 in a state where a part of the insertion body 31 is located inside the cover space 64 . In this case, the fixing protrusion 65 is inserted into the groove portion 34 and positioned, but in contact with the lower portion 33 of the insertion body 31 .

As such, as the fixing protrusion 65 is inserted into the groove portion 34 and the lower portion 33 has a structure in which it is not opened, the insertion unit 2 moves to the outside of the cover unit 3 . It is not removed, and is positioned while being inserted into the cover unit (3).

In this insertion state, when the insertion unit 2 moves in the direction indicated by the arrow, that is, in the downward direction, the insertion body 35 moves downward in the cover space 64 , and accordingly The lower portion 33 of the insertion body 35 is positioned on the lower extension portion 63 along the branch extension portion 62 .

At the same time, the protrusion 35 of the insertion body 31 is positioned while being inserted into the fixing groove 66, and accordingly, the insertion unit 2 is all inserted into the cover unit 3 and position will be fixed.

As will be described later with reference to FIG. 5 , as the insertion unit 2 is all inserted into the cover unit 3 and the position is fixed, the plate parts may be fixed to each other.

Furthermore, from the state in which the position is fixed, when the user holds the head part 10 and moves the insertion unit 2 in the upper direction, the protrusion 35 is removed from the fixing groove 66, The insertion body 31 is moved upward. However, as described above, since the lower part 33 is sealed and thus the fixing protrusion 65 is caught on the lower part 33, the insertion unit 2 is no longer removed to the outside.

As a result, the insertion unit 2 is moved in a preset range only between the fixing protrusion 65 and the lower extension 63, and fixing and releasing can be performed.

The cover unit 6 includes an upper cover 150 and a cover portion 160 .

The upper cover 150 forms the upper part of the cover unit 6, has a larger outer diameter than the cover part 160, and is fixed on the opening of the plate part 200 to be described later. .

In addition, on the upper surface of the upper cover 150, the lower surface 121 of the support part 120 is positioned, and in this way, the lower surface 121 of the support part 120 is in contact with the upper cover 150. In this state, the fixing unit 4 fixes the plate parts.

On the other hand, when the support part 120 is spaced apart from the upper cover 150 and positioned upward, the fixing unit 4 releases the fixing of the plate parts.

The cover part 160 extends downward from the bottom surface 151 of the upper cover 150, and includes an upper extension part 161, a branch extension part 162, a lower extension part 163 and a fixing protrusion ( 165).

The upper extension part 161 extends from the bottom surface 151 of the upper cover 150, and the branch extension part 162 further extends from the upper extension part 161, as shown in FIG. It is characterized in that a pair of branches that are separated from each other are extended together.

In this embodiment, since the length of the cover part 60 is relatively long, the length of the upper extension part 161 is long, and the length of the branch extension part 162 is the length of the upper extension part 161 . It may be formed smaller.

In addition, as a pair of the branch extension parts 162 extend in the lower direction while being spaced apart from each other, as shown in FIG. 3 , the upper extension part 161 and the branch extension part 162 are generally 'U' shaped. It can be extended to have a shape.

In addition, a cover space 164 is formed inside the branch extension 162 , and the insertion body 131 of the insertion unit 5 is positioned in the cover space 164 .

The lower extension part 163 is formed at the end of the branch extension part 162 and extends in a form in which the diameter is extended to the outside of the branch extension part 162 , and as will be described later, the plate part 200 . It is fixed to the lower side of the opening 220 of the position.

That is, the cover unit 6 is fixed to the upper side of the opening 220 as the upper cover 150 has a relatively larger outer diameter than the upper extension 161 and the branch extension 162 . is positioned, and as the lower extension part 163 has a relatively larger outer diameter than the upper extension part 161 and the branch extension part 162, it is fixedly positioned at the lower side of the opening 220 .

Thus, the cover unit 6 is fixedly positioned on the opening of the plate part 200 .

On the other hand, in this embodiment, a first fixing groove 166 and a second fixing groove 167 are formed between the upper extension part 161 and the branch extension part 162, that is, in a portion connected to each other, The first fixing groove 166 may be formed above the second fixing groove 167 .

Accordingly, as shown in FIG. 4B , a protrusion 135 formed in the insertion body 131 is positioned in the first fixing groove 166 or the second fixing groove 167 .

In addition, the fixing protrusion 165 protrudes toward the cover space 164 on the inner surface of the branch extension 162 , and the fixing protrusion 165 is, as described above, of the insertion body 131 . On the groove portion 134 , it is positioned relative to the groove portion 134 .

In the fixing unit 4 having the above structure, the relative movement between the insertion unit 5 and the cover unit 6 will be described with reference to FIGS. 4A and 4B .
