SUMMARY OF THE INVENTION Accordingly, the present invention has been made keeping in mind the above problems occurring in the prior art, and it is an object of the present invention to provide a toy coupling unit that can be relatively fastened with a one-touch fastening structure to improve usability.

In order to achieve the object of the present invention described above, a toy coupling unit according to an embodiment of the present invention is inserted into a fixing member to engage with a fixing member and includes a first unit and a second unit Unit. The first unit includes a first head portion, a first insertion portion extending from the first head portion and inserted into the insertion space, and a second insertion portion extending from the first insertion portion and having a plurality of locking protrusions formed thereon . The second unit includes a second head portion facing the first head portion, a guide portion extending from the second head portion and guiding insertion of the first and second insertion portions, And the fixing part is extended and fixed by the hooking jaws.

In one embodiment, the second insertion portion includes a first locking protrusion protruding in the circumferential direction at an end, and a second locking protrusion protruding in the circumferential direction between the first locking protrusion and the first insertion portion, A first groove portion may be formed between the first engaging jaw and the second engaging jaw, and a second groove portion may be formed between the second engaging jaw and the first insertion portion.

In one embodiment, the fixing portion may include a fixing jaw protruding in the insertion space direction.

In one embodiment, the first unit and the second unit may be in loose engagement with the fixing jaw positioned in the first groove.

In one embodiment, as the first unit is moved to the insertion space of the second unit, the fixing jaw is positioned from the first groove portion to the second groove portion, and the first unit and the second unit are moved The fixing member can be engaged.

In one embodiment, as the first unit is moved into the insertion space of the second unit, the guide portion can be extended outward by the first latching jaw.

In one embodiment, the guide portion may include an end portion protruding from an outer surface of the fixing member at an end thereof and fixing the fixing member and the second unit.

In one embodiment, the guide portion includes a pair of first and second guide portions facing each other, and the fixing portion includes a pair of first and second guide portions opposed to each other between the first and second guide portions, And may include fixed portions.

According to the embodiments of the present invention, it is possible to engage the fixing member by the first and second units while the locking jaws of the first unit are fixed to the fixing unit of the second unit, The engagement of the fixing member can be easily performed only by pushing the unit in the direction of the second unit, and the fixing member can be joined very easily without using a separate tool.

Particularly, the latching jaw is divided into first and second latching jaws to form first and second groove portions, respectively. Since the fixing portion includes the fixing jaw, when the fixing jaw is located in the first groove portion When the fixing jaw is positioned in the second groove portion, the fixing member is engaged. Therefore, the fixing member is fixed in a relatively simple structure, It is possible to easily perform the joining of the members.

In this case, as the first latching jaw extends outwardly of the guide portion, the coupling force to the fixing member is improved.

Further, since the end of the end portion of the guide unit of the second unit protrudes to the outside of the fixing member, the fixing force of the fixing unit with respect to the fixing unit increases as the first unit is inserted and fixed into the insertion space, A predetermined bonding force can be applied to the second electrode.

On the other hand, in the case of releasing the engagement of the fixing member, when the first unit is moved in the opposite direction of the insertion direction, the fixing jaw moves to the first groove, so that the fixing force between the end portion and the fixing member is reduced, Thereby facilitating the release of the member.

Fig. 2 is a perspective view showing the engaged state of the toy coupling unit of Fig. 1; Fig. 3 is a side view showing the first unit and the second unit of the toy coupling unit of Fig. 1 separated; Fig. FIG. 4A is a bottom view of the second unit of FIG. 3 viewed from the lower side, and FIG. 4B is a plan view of the second unit of FIG. 3 observed from above.

1 to 4B, a toy coupling unit 10 according to the present embodiment includes a first unit 100 and a second unit 200, and the first unit 100 includes the second And engages the fixing member which is engaged with the unit 200 and needs to be fixed.

More specifically, the first unit 100 includes a first head portion 110, a first insertion portion 120, and a second insertion portion 130, A first guide part 220, a second guide part 230, a first fixing part 240, and a second fixing part 250. The first fixing part 240, the second fixing part 250,

The first head portion 110 may have a cylindrical shape such as a conventional bolt or a screw and the first insertion portion 120 may protrude from the first head surface 111 of the first head portion 110, And the first insertion portion 120 also has a cylindrical shape.

The second insertion portion 130 extends from the first insertion portion 120 along the extension direction of the first insertion portion 120 and has a first locking protrusion 132 and a second locking protrusion 133 .

The second insertion portion 130 has a cylindrical shape having a smaller radius than that of the first insertion portion 120 and the first and second locking protrusions 132 and 133 have a cylindrical shape having a smaller radius than the first insertion portion 120, And protrude along the circumferential direction to form a latching jaw.

In this case, the first stopping protrusion 132 is located at the end of the second inserting portion 130, and the second stopping protrusion 133 is located between the first stopping protrusion 132 and the first inserting portion 130 120, respectively. A first groove 131 is formed in the circumferential direction between the first and second stopping jaws 132 and 133 and between the second stopping jaw 133 and the first insertion portion 120 And the second trench 134 is formed in the circumferential direction.

At this time, the width of the first groove 131 may be larger than the width of the second groove 134. Thus, as will be described later, when the fixing jaw is located in the first groove 131, the first and second units 100 and 200 are fixed in a relatively weak fixing force in a state that the first and second units 100 and 200 are unlocked, The first and second units 100 and 200 can be firmly fixed when the first and second units 100 and 200 are positioned in the second trench 134.

The second head 210 has a ring shape with an opening at its center, and the second head surface 211, which is an upper surface, faces the first head surface 111. In this case, the second unit 200 forms an insertion space 201 into which the first unit 100 is inserted. When the first unit 100 is inserted into the insertion space 201 and fixed, The second head surface 211 is in contact with the first head surface 111.

The first guide part 220 includes a first guide surface 221 extending from the second head 210 and a first end 222 formed at an end of the first guide surface 221, . In this case, the first guide surface 221 is formed to have a predetermined curvature on the inner surface so that the first and second insertion portions 120 and 130 can be inserted more easily.

The first end portion 222 is protruded in the outer surface direction of the first guide surface 221 and the first guide surface 221 and the first end portion 222 form a step from the outer surface side. In this case, the step is fixed to the outer surface of the fixing member, which will be described later, as will be described later.

The second guide portion 230 is disposed to face the first guide portion 220 and has a second guide surface 231 and a second end portion 232 having a symmetrical shape with respect to the first guide portion 220, ). Accordingly, the insertion space 201 is formed between the first and second guide portions 220 and 230, and the first and second insertion portions 120 and 130 are inserted into the insertion space 201, do.

Meanwhile, in the present embodiment, the guide section includes a pair of first and second guide sections 220 and 230. However, it is obvious that the number of the guide sections can be variously changed.

The first fixing part 240 extends from the second head part 210 between the first and second guide parts 220 and 230 and includes a first fixing surface 241 and a first fixing jaw 242 ).

The first fixing surface 241 guides the first and second insertion portions 120 and 130 in the same manner as the first and second guide surfaces 221 and 231 and the first fixing jaw 242 Is formed at the end of the first fixing surface 241 so as to protrude toward the insertion space 201.

As the first unit 100 is moved in the direction of the second unit 200, the first fixing jaw 242 is positioned on the first groove 131 or the second groove 133 ). &Lt; / RTI >

In this case, the width of the first fixing protrusion 242 may be substantially the same as the width of the second groove 134. Thus, when the first fixing jaw 242 is positioned on the first groove 131, the first and second units 100 and 200 can be relatively moved to maintain the unlocked state, When the first fixing jaw 242 is positioned on the second groove 134, the first fixing jaw 242 and the first groove 134 are engaged and fixed to each other, so that the first and second units 100 And 200 are fixed and combined with each other.

The second fixing part 250 is located between the first and second guide parts 220 and 230 so as to face the first fixing part 240 and has a second fixing surface 251 and a second fixing jaw 240. [ (252).

The second fixing surface 251 and the second fixing jaw 252 have the same shapes as those of the first fixing surface 241 and the first fixing jaw 242, respectively, and overlapping descriptions will be omitted.

The first guide surface 221 is bent toward the insertion space 201 toward the first end 222 and the second guide surface 231 is also protruded toward the second end 232 And is gradually bent toward the insertion space 201. Thus, as shown in FIGS. 4A and 4B, the insertion space 201 has a cross-sectional shape that is closer to an elliptical shape than a circular shape.

It is to be understood that the number of the guide portions and the number of the fixing portions may be variously modified.

Since the first and second guide surfaces 221 and 231 are formed to be bent in the direction of the insertion space 201, as the second insertion portion 130 is inserted into the insertion space 201, The first stopping protrusion 132 pushes the first and second guide surfaces 221 and 231 outwardly. The first and second guide surfaces 221 and 231 extend outwardly and the first and second end portions 222 and 232 also extend outwardly and the first and second end surfaces 222 and 232 are protruded to the outside of the fixing members which are required to be coupled, the bonding force between the first and second end portions 222 and 232 and the fixing members is increased.

As described above, as the first unit 100 is inserted in the direction of the second unit 200, the first and second fixing jaws 242 and 252 are fixed on the second groove part 134 As the first and second guide surfaces 221 and 231 are expanded outward, the first and second end portions 222 and 232 exert a stronger or stronger force on the outer surface of the fixing member . Thus, the fixing members are fixed by the first and second units 100 and 200.

Meanwhile, when the first unit 100 is detached from the second unit 200, the first and second fixing jaws 242 and 252 are positioned on the first groove 131, The first and second guide surfaces 221 and 231 are returned to the inner side so that the fixing force or the coupling force acting on the outer surface of the fixing member is reduced by the first and second end portions 222 and 232, 1 and the second units 100, 200 are detached from the fixing member.

That is, the fixing or removing operation as described above can be easily performed by pushing the first unit 100 into the second unit 200 or pulling the first unit 100 out of the second unit 200 .

FIG. 5 is a perspective view showing a state in which the toy coupling unit of FIG. 1 fixes the pair of fixing members, and FIG. 6 is a sectional view of the fixing state.

5 and 6, a state in which the toy coupling unit 10 engages the fixing members 20 and 30 with each other will be described in detail.

In other words, the first and second units 100 and 200 (the first and second units 20 and 31), which are aligned with the first and second openings 21 and 31 of the second fixing member 30, ) Into the aligned first and second openings (21, 31).

In this case, the first unit 100 is coupled to the second unit 200 in a loose coupling state, and the first and second fixing jaws 242 and 252 are coupled to the first groove part 131 Respectively. The first and second end portions 222 and 232 of the second unit 200 penetrate through the first and second openings 21 and 31 so that the first and second end portions 222 and 232 of the second fixing member 30 And protrudes outwardly.

Thereafter, when the first unit 100 is brought into close contact with the second unit 200, the first head surface 111 and the second head surface 211 are in close contact with each other, 2 fixing jaws 242 and 252 are positioned and fixed on the second groove portion 134 so that the first engaging jaw 132 can move the first and second guide surfaces 221 and 231 outward Push to expand. The first and second end portions 222 and 232 also extend outwardly of the second opening 31 on the outer surface of the second fixing member 30, The fixing force or the coupling force between the end portions 222 and 232 and the second fixing member 30 increases.

Thus, the first and second fixing members 20 and 30 are fixed to each other by the toy coupling unit 10.

On the other hand, when the fixed first and second fixing members 20 and 30 are removed, when the first unit 100 is removed from the second unit 200, do.

According to the embodiments of the present invention as described above, the fixing members can be engaged by the first and second units while the locking jaws of the first unit are fixed to the fixing unit of the second unit. In this case, The engagement of the fixing member can be easily performed only by pushing the first unit in the direction of the second unit, and the fixing member can be joined very easily without using a separate tool.

Particularly, the latching jaw is divided into first and second latching jaws to form first and second groove portions, respectively. Since the fixing portion includes the fixing jaw, when the fixing jaw is located in the first groove portion When the fixing jaw is positioned in the second groove portion, the fixing member is engaged. Therefore, the fixing member is held in the loose state, that is, the loosened state, Can be easily performed.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the present invention as defined by the following claims. It can be understood that it is possible.
