In the following Patent Document 2, 'an assembled toy capable of adjusting a stepwise angle' has been proposed. The applicant has also proposed an assembly assembly and an assembly toy using the same in Patent Document 3 below.

Korean Registered Patent No. 10-0853490 (Date of Announcement: Aug. 22, 2008) Korean Registered Patent No. 10-1129446 (Published March 26, 2012) Korean Registered Patent No. 10-1140326 (Published on May 03, 2012)

Patent Document 1 discloses a toy comprising: a toy member having an assembling opening formed with a plurality of assembling grooves along an outer circumferential surface thereof and at least one arm engaging portion formed through the assembling opening; And an engaging member having a plurality of engaging projections selectively engageable with the engaging groove at various angles and a male engaging portion having a grip portion for engaging the engaging projections with the female engaging portion when the male engaging portion is detached and attached to the female engaging portion, However, since the angle adjustment is not performed in the state where the joining member and the toy member are coupled to each other, it is necessary to separate the joining member and the toy member, and then, the joining must be performed according to the desired angle.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings, and the present invention is not limited to the embodiments.

Hereinafter, the configuration of the assembly assembly 1 according to the preferred embodiment of the present invention will be described.

Figure 1 is a perspective view of an assembly assembly according to a preferred embodiment of the present invention, Figure 2 is an exploded perspective view of the assembly assembly according to Figure 1, Figure 3 is a side view of the assembly assembly according to Figure 1, Fig. 5 is a perspective view showing the housing part of the assembling assembly according to Fig. 1, Fig. 6 is a perspective view showing the engaging block of the assembling assembly according to Fig. 1, Fig. 7 is a perspective view showing the assembling assembly according to Fig. Side view showing a combined block of the assembly.

An assembling assembly (1) according to the present invention is an assembling assembly for assembling a plurality of parts to each other. The assembling assembly is inserted into parts constituting an assembling toy, a household appliance, etc., A housing unit 10 having a plastic deformation engaging part 110 in which an installation space S is formed and protruded from a center of the installation space S; And a coupling block 20 having a through hole 210 formed at a central portion thereof and including a plurality of coupling pieces 220 formed in a circumferential direction about the through hole 210.

The housing part 10 constitutes the external appearance and framework of the assembling assembly 1 according to the present invention and is inserted and fixed in an installation groove (not shown) formed in each component such as a toy or a household appliance, An installation space S is formed (see Fig. 2).

As shown in Figs. 1 to 3, the housing part 10 is formed in a substantially cylindrical shape, and the mounting space S is formed in a substantially cylindrical shape corresponding to the cylindrical part, and the upper side thereof is opened.

The joining block 20 is rotatably inserted into the installation space S at the central portion of the installation space S and is provided with a plastic deformation engaging portion 110 protruded upward. At this time, the plastic deformation joining portion 110 is formed so as to protrude through the through hole 210 of the coupling block 20. The plastic deformation joining portion 110 may be formed to have a hollow inside.

When the coupling block 20 is rotatably inserted into the installation space S, the end of the plastic deformation coupling part 110 is pressed by a punch or the like, and the plastic deformation coupling part 110 is lowered in height from the upper end And extends outward in the direction in which the diameter increases to cover the outer periphery of the through hole 210.

Plastic deformation of the plastic deformation joining portion 110 causes the joining block 20 to be engaged with the housing portion 10 while being inserted into the installation space S of the housing portion 10 so as not to be arbitrarily separated. At this time, the coupling force between the housing part 10 and the coupling block 20 due to plastic deformation of the plastic deformation coupling part 110 is such that the coupling block 20 rotates in the installation space S of the housing part 10 It should be possible.

In order to prevent the outer side of the plastically deformed plastic deformation engaging portion 110 from being brought into contact with the inner side surface of the engaging piece 220 of the engaging block 20 during the plastic deformation of the plastic deformation engaging portion 110, A plastic deformation receiving groove 232 may be formed around the circumferential outer circumference of the through hole 210 of the coupling block 20 (see FIG. 6).

The structure including the plastic deformation engaging portion 110 and the through hole 210 for rotatably coupling the coupling block 20 into the installation space S of the housing portion 10 as described above is disclosed in Patent Document 3 is relatively simple compared to a structure for rotatably coupling a coupling block within a housing. Therefore, the assembling assembly 1 according to the present invention has an advantage that the production cost is low.

The gear portion 120 is a portion that engages with the gear portion 120 of the other assembly assembly 1 and serves to maintain the angle of engagement between the two assembly assemblies 1 coupled to each other, As shown in FIG.

The gear portion 120 is exposed to the outside when the assembling assembly 1 according to the present invention is inserted and fixed in the insertion groove of a toy or a household appliance part. As shown in FIGS. 1 to 5, And is formed in a gear shape. The gear portion 120 functions to prevent the pair of assembly assemblies 1 from rotating arbitrarily by engaging with each other in a state where they are coupled to each other by the elastic force of the coupling block 20. [

The gear portion 120 is formed so as to surround the upper exit edge of the installation space S of the housing portion 10 and to have a narrower width toward the uppermost protruding portion, The engagement with the portion 120 is facilitated.

The coupling protrusions 130 are formed in the housing part 10 so that the housing part 10 can be press-fitted into the installation groove of the toy or the household appliance parts when the assembly assembly 1 according to the present invention is inserted and fixed. A plurality of protrusions are formed on the outer circumferential surface.

That is, the plurality of engaging projections 130 on the outer circumferential surface of the housing part 10 are deformed in the process of being inserted into the installation grooves of the toys, household appliance parts, etc., Even if a rotational force is applied to the housing part 10 in a state in which the assembly assembly 1 according to the present invention is inserted and fixed in a mounting groove of a toy or a household appliance part or the like, The coupling force is increased so as not to be arbitrarily rotated relative to a toy or a household appliance part. Therefore, much better bonding force can be obtained as compared with the case where only the adhesive is used to fix the assembly assembly 1 to the installation groove of the toy or the household appliance part.

The coupling block 20 is inserted into the installation space S of the housing part 10 and is rotatably engaged as a part which substantially enables the coupling between the pair of assembly assemblies 1. [ This is for allowing the pair of coupling blocks 20 to rotate naturally in a direction in which they can engage with each other in the process of coupling with the other assembly assembly 1. [

The coupling block 20 includes a through hole 210 formed at a central portion thereof; A block body 230 formed in a plate shape so as to correspond to an installation space S of the housing part 10; And a plurality of coupling pieces 220 formed in a circumferential direction about the through holes 210. [

2, 6 and 7, the block body 230 is formed in a plate shape corresponding to the installation space S of the housing part 10, and may be formed in a disc shape.

The through hole 210 is formed at a central portion of the block body 230 so that the plastic deformation joining portion 110 of the housing portion 10 can be penetrated.

As described above, when the coupling block 20 is rotatably inserted into the installation space S, the end of the plastic deformation joining portion 110 is pressed by a punch or the like, and the plastic deformation joining portion 110 has a height The diameter of the through hole 210 is enlarged outwardly so as to cover the outer periphery of the through hole 210.

The plastic deformation receiving groove 232 may be formed around the circumferential outer circumference of the through hole 210 of the coupling block 20 (see FIG. 6).

The engaging piece 220 substantially enables the coupling between the pair of engaging blocks 20, and is formed in a plurality of circumferential directions around the through hole 210 and is formed at equal intervals from each other. That is, a plurality of protrusions are formed in the direction of the outer side (upper side) of the installation space S from the upper surface of the block body 230. Each of the engagement pieces 220 includes a positioning engagement piece 221 and an elastic engagement piece 222 .

In the present embodiment, the coupling pieces 220 are formed on the upper surface of the block body 230 at equal intervals, but may be formed of two, three, or more than five.

The positioning fittings 221 allow the pair of fitting blocks 20 to rotate naturally in a direction in which the pair of fitting blocks 20 can be engaged with each other in the process of coupling with the other assembly assembly 1, (Upper end portion) of the positioning engagement piece 221 protrudes from the upper surface of the block body 230 so that at least a part (upper end portion) of the positioning engagement piece 221 is located outside the upper side .

The elastic coupling piece 222 is formed in a cantilever shape protruding in the same direction as the positioning coupling piece 221 at one side of the positioning coupling piece 221. [ 3, at least a part (an upper end portion) of the elastic coupling piece 222 is also protruded from the upper side of the block body 230. The elastic coupling piece 222 is also protruded from the upper surface of the block body 230, As shown in Fig. However, the height of the upper end of the elastic coupling piece 222 protruding outside (upper side) of the installation space S is formed to be lower than the height of the upper end of the positioning coupling piece 221. This is because the upper end of the positioning engaging piece 221 of the other engaging block 20 is elastically engaged with the other end of the elastic engaging piece 20 when the pair of engaging blocks 20 are naturally rotated in a direction in which the pair of engaging blocks 20 can engage with each other, So that it is not caught by the upper end of the base plate 222.

In addition, a locking protrusion 222a protrudes from one end (upper end) of the elastic coupling piece 222 toward the outer side (upper side) of the installation space S. The engagement protrusions 222a are engaged with the engaging protrusions 222a of the elastic engagement pieces 222 of the other engagement block 20 when the pair of engagement blocks 20 are engaged with each other, To be engaged with each other.

For this purpose, when the upper ends of the pair of elastic engagement pieces 222 come into contact with each other in the process of coupling the pair of engagement blocks 20 to each other, the elastic engagement piece 222 is elastically deformed in the direction of the positioning engagement piece 221 An inclined surface or a curved surface is formed at the upper end of the elastic engagement piece 222 so that the height in the direction close to the positioning engagement piece 221 becomes higher and the height in the direction in which the engagement protrusion 222a is formed becomes lower .

The inclined surface of the upper end portion of the elastic engagement piece 222 is extended so as to form the same surface as the upper surface of the one side engagement tab 222a. Accordingly, when the pair of coupling blocks 20 are engaged with each other, the inclined surfaces of the upper ends of the pair of elastic coupling pieces 222 are brought into contact with each other and slid with each other, and then the upper ends of the pair of engagement jaws 222a The engaging protrusions 222a of the other elastic engaging pieces 222 can be lowered below the engaging protrusions 222a formed on one side of the elastic engaging pieces 222 by sliding the inclined surfaces to each other.

That is, the elastic coupling piece 222 is elastically deformed in the direction of the positioning coupling piece 221 by the contact with the other elastic coupling piece 222 while the pair of coupling blocks 20 are coupled to each other, The engaging protrusions 222a of the other elastic engaging pieces 222 are positioned below the engaging protrusions 222a and the pair of engaging protrusions 222a are engaged with each other while being restored to a circular shape, So that the blocks 20 can be combined with each other.

The bottom surface of the latching jaw 222a is formed to be inclined or curved. This is because, in the process of separating the pair of assembly assemblies 1 from each other, the slopes or curved surfaces of the bottom surfaces of the pair of the engagement protrusions 222a are brought into contact with each other and slid with each other, so that a pair of engagement blocks 20, So that it can be separated. The elastic deformation of the elastic engagement piece 222 and the circular restoration can be achieved.

In the present embodiment, the elastic coupling piece 222 has a shape substantially the same as that formed by cutting a part of the coupling piece 220. That is, the engaging pieces 220, which are formed in a plurality of circumferential directions around the through hole 210, are partially cut to form a positioning engaging piece 221 having a relatively large volume and an elastic engaging piece 221 having a relatively small volume 222). ≪ / RTI >

In other words, a space portion formed concavely inwardly inward is formed on one side of the positioning engagement piece 221, and the elastic engagement piece 222 is engaged with the positioning engagement piece 221 in the space formed in one side of the positioning engagement piece 221, Like shape protruding in the same direction as the cantilever shape.

The lower portion of the positioning coupling piece 221 and the lower portion of the elastic coupling piece 222 are integrally formed and the upper portion of the positioning coupling piece 221 and the upper portion of the elastic coupling piece 222 are separated from each other, A separation groove 223 having a wedge-shaped cross section is formed between the piece 221 and the elastic engagement piece 222 for elastic deformation of the elastic engagement piece 222 (see FIG. 7).

In this embodiment, as shown in Figs. 1, 2, 4, and 6, a wedge-shaped cross-section is formed between the positioning engagement piece 221 and the elastic engagement piece 222 in a shape similar to an ' The separation groove 223 is formed.

The width of the inner surface of the positioning piece 221 closer to the through hole 210 is narrower than the width of the inner surface of the positioning piece 221 close to the through hole 210 of the coupling piece 220, The width of the outer side surface remote from the hole 210 is formed to be the same as the width of the outer side surface remote from the through hole 210 of the engagement piece 220.

However, the present invention is not limited thereto, and the shape of the separation groove 223 may be formed in various shapes within a range where the elastic engagement piece 222 can be elastically deformed.

For example, in order to divide the engaging pieces 220, which are formed in a plurality of circumferential directions around the through holes 210 at a ratio of approximately 2: 1, a straight line extending in the circumferential direction from the center of the through holes 210 The separation groove 223 may be formed.

In the above description, the lower portion of the positioning coupling piece 221 and the lower portion of the elastic coupling piece 222 are integrally formed. However, the present invention is not limited thereto, and the positioning coupling piece 221 and the elastic coupling piece 222 may protrude from the upper surface of the block body 230, respectively. In this case, the lower end of the separation groove 223 having a wedge-shaped cross section can be located on the same plane as the upper surface of the block body 230 or lower than the upper surface of the block body 230.

Although the separation groove 223 has been described as having a wedge-shaped cross section in the above description, the present invention is not limited thereto. The separation groove 223 may be formed to have the same width regardless of the height, Respectively.

The upper end of the positioning coupling piece 221 is formed into a convex shape whose width decreases toward the upper part so that the pair of the coupling blocks 20 can be naturally rotated in a direction in which the pair of the coupling blocks 20 can be engaged with each other in the process of coupling with the other assembly assembly 1. [ do.

Therefore, when the upper ends of the pair of positioning engagement pieces 221 come into contact with each other in the process of coupling the pair of the engagement blocks 20 to each other, the most convex portion of the upper end of the other positioning engagement piece 221 comes into contact with the positioning engagement piece The coupling block 20 is naturally rotated so that the coupling piece 220 of the other coupling block 20 can be fitted into the space between the coupling pieces 220. [

The width of the outer surface of the positioning piece 221 far from the through hole 210 is formed to have the same width as the outer surface far from the through hole 210 of the coupling piece 220, Since the most convex portion of the upper end of the positioning engagement piece 221 slides along the inclined surface of the upper end of the positioning engagement piece 221 and is rotated without any step on the inclined surface, So that it can be smoothly and naturally rotated.

As described above, the engaging piece 220 including the positioning engaging piece 221 and the elastic engaging piece 222 has a shape that can be formed relatively low in height compared to the engaging piece and the engaging head of Patent Document 3 The assembly assembly 1 according to the present invention has an advantage that it can be manufactured at a relatively low height. Therefore, there is an advantage in that the space required for mounting on the assembling toy, the components constituting the household appliance, and the like is reduced.

The engagement piece 220 having the above-described structure is advantageous in increasing the number of engagement pieces 220 protruding from the upper surface of the block body 230 relative to the engagement piece and the engagement head of Patent Document 3 Respectively. Further, even if the number of the coupling pieces 220 provided in the coupling block 20 is increased, the coupling force and durability of the respective coupling pieces 220 are not lowered.

In particular, since a relatively large number of the coupling pieces 220 can be protruded from the upper surface of the block body 230, when one coupling piece 220, the elastic coupling piece 222, or the locking tab 222a is damaged There is an advantage that the coupling force of the entire assembling assembly 1 is not significantly lowered.

1 and 6, an elastic slit 231 passing through the block body 230 may be formed at a lower end of one side of the elastic coupling piece 222. As shown in FIG. Such an elastic slit 231 facilitates the elastic deformation of the elastic engagement piece 222 and causes cracks to be generated from the connection portion with the block body 230 during the repeated elastic deformation of the elastic engagement piece 222 . It is appropriate that the number of elastic slits 231 is the same as the number of the elastic engagement pieces 222 of the engagement piece 220 protruding from the upper surface of the block body 230.

7, a through hole 210 is formed in the lower surface of the block body 230 of the coupling block 20 rotatably inserted in the installation space S of the housing part 10, And an outer boss 235 protruding downward in the circumferential outer circumference of the boss 235 may be formed.

2 and 6, on the inner bottom surface of the housing part 10, a boss 235 protruding from the center part is formed on the inner bottom surface of the housing part 10 so that the outer boss 235 of the coupling block 20 can be inserted and rotatably seated. An outer boss seating groove 115 may be formed around the circumferential outer circumference of the deformable joint portion 110.

Hereinafter, a process of coupling a pair of the assembly assemblies 1 having the above-described configuration to each other will be described.

9 is a perspective view showing a state where a pair of assembly assemblies according to a preferred embodiment of the present invention are coupled to each other, and FIG. 10 is a cross- FIG. 2 is a side view showing a state where a pair of coupling blocks are coupled to each other. FIG.

Practically, the pair of assembly assemblies 1 are fixedly mounted on different toys or parts of household appliances constituting one toy or household appliance to enable the coupling between them, (1) are directly coupled to each other.

When the user moves the pair of assembly assemblies 1 in the direction of approaching each other, the upper ends of the pair of outermost positioning engagement pieces 221 come into contact with each other as shown in Figs. 3 and 8 .

At this time, the engaging pieces 220 of the one engaging block 20 are staggered with respect to the engaging pieces 220 of the other engaging block 20. That is, 220, and FIG. 8 shows a state in which they are set in such a direction as to be offset from each other.

However, even if a pair of the coupling blocks 20 is not set in a direction in which they are staggered with each other, the pair of coupling blocks 20 can be relatively rotated in a proper direction have.

This is because the upper end of the positioning engagement piece 221 is formed in a convex shape whose width decreases as the distance from the upper end of the positioning engagement piece 221 increases. The most convex portion of the upper end of the other positioning engagement piece 221 slides along the inclined surface of the upper end of the positioning engagement piece 221, so that the engagement block 20 is naturally rotated.

When the engaging pieces 220 of the pair of engaging blocks 20 are set in a direction in which the engaging pieces 220 of the pair of engaging blocks 20 are offset from each other, the inclined surfaces of the upper ends of the engaging jaws 222a of the pair of the engaging blocks 222 come into contact with each other. Here, when the user applies an additional force to move the pair of assembly assemblies 1 in the direction approaching each other, the pair of elastic engagement pieces 222 are elastically deformed toward the positioning engagement piece 221, The engaging protrusions 222a of the other elastic engaging pieces 222 are positioned below the formed engaging protrusions 222a and the engaging protrusions 222a are engaged with each other while being restored to a circular shape, The coupling blocks 20 are coupled to each other (see Fig. 10).

At the same time, the gear portion 120 of one of the housing portions 10 is engaged with the gear portion 120 of the other housing portion 10. Accordingly, when the pair of assembly assemblies 1 are engaged with each other by the elastic force of the coupling block 20, the pair of gear parts 120 are engaged with each other, so that the pair of assembly assemblies 1 are not arbitrarily rotated relative to each other I can not.

As described above, the assembling assembly 1 according to the present invention has an advantage that a certain angle can be maintained because the pair of assembling assemblies 1 are coupled to each other without arbitrarily rotating relative to each other.

With the pair of assembly assemblies 1 engaged with each other as described above, the user can relatively rotate the parts or the like in which the respective assembly assemblies 1 are fixedly installed. That is, the pair of assembly assemblies 1 can be rotated relative to each other without detaching them. This is because the coupling block 20 of each assembly assembly 1 is rotatably coupled within the housing part 10. [

At this time, since the gear portions 120 of the pair of assembled assemblies 1 are engaged with each other, the user relatively rotates the two parts with a sufficient force to release the meshed state of the gear portion 120 do.

In this case, the inclined surfaces or the curved surfaces of the bottom surfaces of the pair of engaging protrusions 222a which are engaged with each other are slid with respect to each other, so that the distance between the pair of engaging blocks 20 coupled to each other is increased, The gear portion 120 is relatively rotated by the applied rotational force and the required angle is changed. Then, when the rotational force is removed, the coupling force between the pair of the engagement protrusions 222a is restored, Will again engage. Thus, a new coupling angle between the two parts can be maintained.

As described above, the assembly assembly 1 according to the present invention has an advantage that the angle can be adjusted by rotating the coupling without disassembling in a state where the pair of assembly assemblies 1 are coupled to each other.

Meanwhile, when the user strongly pulls the pair of assembly assemblies 1 in a direction away from each other in order to separate the pair of assembly assemblies 1 from each other, a pair of the engagement protrusions 222a, The pair of assembly blocks 1 are separated from each other while the pair of engagement blocks 20 coupled to each other are naturally separated from each other.

The assembly assembly according to the present invention can be easily detached from a pair of assembly assemblies having the same structure and can be easily detached from each other, .

Further, since the operator can be coupled to each part without having to distinguish between the female coupling member and the male coupling member, the work speed can be improved and only a small number of assembly assemblies can be purchased, thereby reducing the purchase cost.

Further, there is an advantage that the bar assembly assembly having the engagement piece having the shape of a relatively low height can be manufactured at a low height, and the space required for mounting the assembly to each component is reduced.

In the housing part of the assembling assembly according to the present invention, the gear part is engaged with the gear part of the other assembling assembly. In the state where the pair of assembling assemblies are coupled to each other, the two parts are not rotated relative to each other, There is an advantage that can be.

There is an advantage that the assembled assembly can be rotated without being disassembled and the angle can be adjusted while the pair of assembly assemblies are coupled to each other.

Also, even when a plurality of coupling pieces are provided in the coupling block of the assembly assembly according to the present invention, there is an advantage that the coupling force and durability are not reduced and the coupling force is not significantly decreased even when one coupling piece is broken.

Further, the structure for coupling the coupling block in a rotatable state within the housing is simple, which is advantageous in that the production cost is reduced.
