Description

Combination unit for toys with improved fixing power {COMBINING UNIT WITH INCREASED COMBINING FORCE}

The present invention relates to a coupling unit for a toy, and more particularly, to a coupling unit for a toy with improved fixing force that can be applied to a toy or various assembly devices, and can be easily fixed and released in various combinations.

A fastening unit or a coupling unit for manufacturing a structure or shape desired by a user by being applied to a toy or various assembly devices has been developed in various ways.

In particular, since various types of assembly devices are used as a part of education or hobbies, not only children, but also adolescents and adults, the range in which the fastening unit or the coupling unit is used is increasing.

For example, Korean Patent Registration No. 10-1758628 discloses a coupling unit for a toy that is inserted into inserts formed in the to-be-coupled objects of a toy to couple the to-be-coupled objects.

However, in the case of the various types of coupling units that have been developed in the prior art, as well as the disclosed patents, there is a limit to the application as it is as the structure or shape used is changed, and a change in design is required.

Furthermore, in the case of many coupling units, once coupled, they have a structure that is difficult to recombine, and even in the case of a structure that can be recombined, a problem of reduced durability occurs during repeated recombination, and a significant degree of external force is required during insertion or release. There is a problem in that it is difficult to use by relatively young users.

Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the accompanying drawings.

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. 2 is a cross-sectional view illustrating a fixing state of the fixing unit of FIG. 1 .

1 and 2, the toy coupling unit (8, see FIGS. 4a and 4b) according to this embodiment includes a fixing unit 1 and a plate part (200, see FIGS. 4a and 4b), and , the fixing unit (1) is inserted into the plate part (200), characterized in that the plurality of overlapping plate parts are fixed to each other.

In this case, the plate part 200 will be described later with reference to FIGS. 4A and 4B , and only the fixing unit 1 will be described below.

That is, the fixing unit 1 is inserted and positioned in the plate part 200 , and 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), 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 part 10 has a predetermined thickness, and when combined with the plate part 200 to be described later, is positioned to protrude from the top of the plate part 200 .

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 coupled to 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 when the insertion body 31 is inserted into the cover unit 3, its shape does not change and is fixed. It will maintain the shape of a rectangular block or bar.

The protrusion 35 is formed to protrude as a pair on the upper side of the insertion body 31, that is, a position adjacent to the upper part 32, and a lower side, that is, a position adjacent to the lower part 33, the insertion body. It may protrude from the surface where the groove part 34 is not formed in the 31 .

The protrusion 35 is positioned to move along the cover space 64 of the cover unit 3, which will be described later, so that the insertion unit 2 is movable on the cover unit 3 through this. do.

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 lower surface 21 of the support part 20 is positioned, and in this way, the lower 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 part 60 extends downward from the bottom surface 51 of the upper cover 50 and includes an upper extension part 61 , a branch extension part 62 , and a lower extension part 63 .

The upper extension part 61 extends from the bottom surface 51 of the upper cover 50, and the branch extension part 62 further extends from the upper extension part 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 entire 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 moved and positioned in the cover space 64 .

The lower extension portion 63 is formed at the end of the branch extension portion 62, and extends in a form in which a diameter is extended to the outside of the branch extension portion 62, and as will be described later, the plate portion 200 It is fixed to the lower side of the opening 220 of the position.

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 part 61 and the branch extension part 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 .

Meanwhile, in the present embodiment, a portion adjacent to the upper extension portion 61 of the branch extension portion 62 is spaced apart from each other by a pair wider than a portion adjacent to the lower extension portion 63 .

That is, as the branch extension part 62 goes downward, the distance between the pair of them becomes narrower, and accordingly, the cover space 64 formed inside the branch extension part 62 is also lowered. As you go further, the size of the space becomes narrower.

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 FIG. 2 .

That is, referring back to FIG. 2 , the insertion unit 2 is moved only within a predetermined stroke range at the position inserted into the cover unit 3 , and the lower protrusion of the protrusion 35 is the cover. A stroke that is located in the upper part of the space 64 or an upper protrusion of the protrusion 35 is positioned above the cover space 64 , that is, a stroke equal to the interval between the upper and lower protrusions 35 . It can be moved in range.

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 lower protrusion 35 is positioned above the cover space 64 .

As such, as the protrusion 35 is positioned on the upper portion of the cover space 64 , the insertion unit 2 is not removed to the outside of the cover unit 3 , but is inserted into the cover unit 3 . will be positioned as

In this inserted state, when the insertion unit 2 moves in the direction indicated by the arrow, that is, in the downward direction, the insertion body 31 moves downward in the cover space 64 , and accordingly The lower portion 33 of the insertion body 31 is positioned on the lower extension portion 63 along the branch extension portion 62 .

At the same time, the protrusion 35 of the upper side of the insertion body 31 is positioned into the cover space 64, and accordingly, the insertion unit 2 is 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.

On the other hand, in this case, as the insertion body 31 of the insertion part 30 moves into the cover space 64 , that is, moves in the downward direction, the pair of the pairs that are spaced apart and narrow toward the bottom. The branch extension parts 62 are spaced apart from each other and expand.

That is, by direct contact with the insertion body 31, the spacing between the pair of branch extension parts 62 is expanded, and by this expansion, contact and fixing force with the plate parts, which will be described later, are improved.

Furthermore, when the user holds the head portion 10 and moves the insertion unit 2 in the upward direction from the fixed position, the insertion body 31 moves upward, and accordingly The separation distance between the pair of branch extension parts 62 is narrowed again to be positioned in the initial state, and thus the contact and fixing force with the plate parts is reduced. However, as described above, the insertion unit 2 is not removed to the outside of the cover unit 3 due to the lower protrusion 35 .

As a result, the insertion unit 2 is moved in a preset range while being inserted into the cover unit 3, and fixing and releasing can be performed.

Figure 3 is a perspective view showing a fixing unit of the coupling unit for a toy according to another embodiment of the present invention.

Since the fixing unit 4 in this embodiment is substantially the same as the fixing unit 1 described with reference to FIGS. 1 and 2 except that the length is formed to be longer overall, for the same components, The same reference numerals are used, and overlapping descriptions are omitted.

That is, since the fixing unit 4 in this embodiment has a longer overall length, a greater number of plate parts can be coupled to each other, which will be described later with reference to FIGS. 4A and 4B .

Referring to FIG. 3 , the toy coupling unit 8 according to this embodiment includes a fixing unit 4 and a plate part 200 , and the fixing unit 4 is inserted into the plate part 200 . , characterized in that the plurality of overlapping plate parts are fixed to each other.

In this case, the plate part 200 will be described later with reference to FIGS. 4A and 4B , and only the fixing unit 4 will be described below.

That is, the fixing unit 4 is inserted and positioned in the plate part 200 , and specifically, it includes an insertion unit 5 and a cover unit 6 .

3 shows a state in which the insertion unit 5 and the cover unit 6 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 4), the insertion unit 5 is inserted into the cover unit 6, and it is characterized in that it moves only within a predetermined stroke range.

In this embodiment, the insertion unit 5 and the cover unit 6 are characterized in that the length of the insertion part 30 and the cover part 60 is relatively long.

As the insertion portion 30 is formed to be relatively long, the length of the groove portion 34 formed inside the insertion body 31 also increases. As the length of the groove portion 34 increases, There is a fear that the rigidity of the insertion body 31 is weakened, which may affect the fixing force or durability.

Accordingly, as shown, the auxiliary frame 36 is formed to extend a predetermined length on the upper side of the groove portion 34, and accordingly, the length of the groove portion 34 is reduced and maintained at an appropriate length, through which the By maintaining the rigidity of the insertion body 31, it is possible to improve the fixing force and durability.

In addition, as the length of the cover part 60 also increases relatively, the length of the upper extension part 61 of the cover part 600 increases, and a fixing groove 66 is formed on the upper extension part 61 . can be formed.

In this case, as the pair of branch extension parts 64 extend in the lower direction, the distance between each other becomes narrower, and the insertion body ( As the 31) moves, the distance between the branch extension parts 64 is widened and the fixing force is improved, so that the fixing to the plate part is performed as described above.

On the other hand, a pair of protrusions 35 spaced apart from each other are also formed on the insertion body 31. In the initial state in which the insertion unit 2 is inserted into the cover unit 3, the upper side The protrusion 35 may be positioned by being inserted into the fixing groove 66 . Thus, the insertion unit 2 is positioned in a state coupled to each other without being removed from the cover unit 3 to the outside.

On the other hand, when the insertion unit 2 is further moved to the inside of the cover unit 3 to perform coupling with the plate parts, the upper protrusion 35 inserted into the fixing groove 66 is It is moved to the lower part to be located in the cover space (64).

That is, as described above, even in this embodiment, as the pair of protrusions 35 and the fixing groove 66 are formed, when the insertion unit 2 is coupled on the cover unit 3, It is moved only within the range of a certain stroke, and engagement and disengagement operations can be performed.

4A and 4B are cross-sectional views illustrating a state in which the fixing units of FIGS. 1 and 3 are fixed to the plate unit.

4A and 4B, the coupling unit 8 is the fixing unit 1 in FIG. 1 or the fixing unit in FIG. (4) is inserted to fix the plate parts.

In this case, each of the plate parts includes an opening 220 having the same shape as each other, and a plurality of the openings 220 may be formed in each of the plate parts in a predetermined predetermined arrangement.

That is, the plate parts have a so-called plate shape and are formed to extend in a plane, and as illustrated, the area of each plate part may be formed to be the same.

However, the area of the plate parts may be formed differently, and each plate part forms a predetermined surface in consideration of the structure of the final assembled shape, but has various shapes, for example, 'a' shape, It may be formed in the shape of a 'C' or the like.

However, as described above, even if the shape of the plate parts are all different, the arrangement of the openings 220 formed in the plate parts, that is, the spacing between adjacent openings, and the structure and shape of each of the openings are all the same. should be formed

Thus, with respect to the plate portions overlapping each other, it is possible to perform coupling through the fixing units (1, 4) described with reference to FIG. 1 or FIG.

On the other hand, each of the openings 220 is formed to pass through the plate portion, and forms a so-called coupling surface 230 while passing through the plate portion.

At this time, the coupling surface 230 is an upper jaw 231 forming a step from the upper surface of the base portion 210, which is the frame of the plate portion 200, and forming a step from the lower surface of the base portion 210 A lower jaw 233 and a contact surface 232 connecting the upper jaw 231 and the lower jaw 233 to each other are formed.

In this case, the upper jaw 231 and the lower jaw 233 are only different in position from each other, and have a symmetrical shape and structure.

In addition, a radius of a circle that is a cross-section formed by the contact surface 232 is smaller than a radius of a circle that is a cross-section formed by the upper jaw 231 or the lower jaw 233 . Accordingly, as a whole, the coupling surface 23 is characterized in that both ends are wide and the contact surface in the center is formed relatively narrow, as shown in the figure.

On the other hand, in the case of the fixing unit 1 described in FIG. 1, since the length of the insertion part 30 is relatively small, as shown, in order to combine the two overlapping plate parts 202 and 203 can be used

More specifically, in order to combine the plate parts 202 and 203, first, the cover unit 3 in which the insertion unit 2 is located is aligned with each other of the two plate parts 202 and 203. It is inserted into the located openings 220 .

Through this, the upper cover 50 of the cover unit 3 is positioned and fixed on the upper jaw 231 of the plate part 202 located on the upper side, and the lower extension part 63 is located on the lower side. It is positioned and fixed on the lower jaw 233 of the plate part 203 .

Thus, the upper extension portion 61 and the branch extension portion 62 are positioned through the contact surfaces 232 of the plate portions 202 and 203 .

In this case, since the insertion part 30 is not located on the cover space 64 side of the branch extension part 62, the branch extension part 62 may have a predetermined elasticity in the left and right directions, Accordingly, the cover unit 3 may be inserted through the opening 220 of the plate parts 202 and 203 stacked on each other.

That is, when the insertion unit 2 moves downward toward the cover unit 3 , the insertion unit 30 moves downwardly from the inside of the cover space 64 , and thus, The branch extension portion 62 is spread to both sides, and the contact force between the branch extension portion 62 and the contact surface 232 is improved, thereby improving the fixing force. In this case, the protrusion 35 is positioned on the cover space 64 between the branch extension parts 62 .

Thus, the fixing unit 1 couples the two overlapping plate parts 202 and 203 to each other.

In order to release the coupling of the plate parts 202 and 203, it is sufficient to move the insertion unit 2 upward of the cover unit 3, and accordingly, the insertion unit ( 2) is located.

Thereafter, the fixing unit 1 may be removed from the plate portions 202 and 203 to release the coupling.

On the other hand, in the case of the fixing unit 4 described with reference to FIG. 3 , since the length of the insertion part 130 is relatively long, as shown, three overlapping plate parts 201 , 202 , 203 are installed. can be used to combine.

More specifically, in order to couple the plate parts 201, 202, 203, first, the cover unit 6 in which the insertion unit 5 is located is connected to the three plate parts 201, 202, 203. is inserted into the openings 220 positioned in a line with each other.

Through this, the upper cover 50 of the cover unit 6 is positioned and fixed on the upper jaw 231 of the plate part 200 positioned at the uppermost side, and the lower extension part 163 is the lowermost part. It is positioned and fixed on the lower jaw 233 of the plate part 203 located in the .

Thus, the upper extension portion 61 and the branch extension portion 62 are positioned to pass through the contact surfaces 232 of the plate portions 201 , 202 , and 203 .

In this case, since the insertion part 30 is not located on the cover space 64 side of the branch extension part 62, the branch extension part 62 may have a predetermined elasticity in the left and right directions, Accordingly, the cover unit 6 may be inserted through the opening 220 of the plate parts 201 , 202 , 203 stacked on each other.

At this time, the upper protrusion 35 is positioned on the fixing groove 66 .

After that, when the insertion unit 5 moves downward toward the cover unit 6 , the insertion unit 30 moves downward from the inside of the cover space 64 , and thus , the branch extension 62 is spread to both sides, the contact force between the branch extension 62 and the contact surface 232 is improved, thereby improving the fixing force. In this case, the protrusion 35 is positioned on the cover space 64 between the branch extension parts 62 .

Thus, the fixing unit 4 couples the three plate parts 201 , 202 , 203 overlapping each other with each other.

In order to release the coupling of the plate parts 201 , 202 , 203 , it is sufficient to move the insertion unit 5 upward of the cover unit 6 , and accordingly, the position in the initial state, that is, the The insertion unit 5 is positioned in a state where the upper protrusion 35 is positioned in the fixing groove 66 .

Furthermore, as shown, in order to couple the four overlapping plate parts 201 , 202 , 203 , 204 to each other, the fixing unit 7 designed to have a longer length of the insertion part may be applied.

As described above, in this embodiment, the coupling unit 8 has the length of the insertion part and the cover part of the fixing unit in consideration of the total coupling height according to the number of the overlapping, that is, plate parts to be coupled. can be designed.

According to embodiments of the present invention, in a state in which the cover unit and the insertion unit inserted therein are integrally inserted into the plate parts, the insertion unit is controlled to move only within a predetermined stroke range, so that the plate part Since it can be fixed or released, the operation of fixing and releasing the plate parts can be performed very easily.

In particular, since the insertion unit inserted into the cover unit is moved only within a preset range between the fixing protrusion and the fixing groove to perform the fixing and releasing operations of the plate parts, the user can easily check the fixing or releasing state. Of course, the convenience and ease of the user's fixing or releasing operation is improved.

In addition, in the structure in which the insertion part extends in a bar shape and has a structure in which the shape is maintained, and the branch extension part of the cover part extends so that the gap becomes narrower in the lower direction in the initial state, according to the insertion of the insertion part, the As the separation interval of the branch extension is extended, it has a structure that improves fixing force with the plate parts, so that it can be stably fixed with the plate parts while having a relatively simple structure.
