Description

assembly assembly

The present invention relates to an assembly assembly, and more specifically, an assembly assembly in which a plurality of products can be easily assembled and separated using magnets, and the two products can be rotated at regular angular intervals while assembled by magnets. It's about.

Unless otherwise indicated herein, the material described in this section is not prior art to the claims of this application, and is not admitted to be prior art by inclusion in this section.

In general, assembly for combining a plurality of parts has various assembly structures. These assembled assemblies are used in a variety of fields, including assembly toys that must be easily assembled and disassembled.

An assembly toy is a toy that involves putting together parts of various shapes and then disassembling them to play. The materials of assembly toys are diverse, such as paper, wood, metal, and plastic, and the assembly method includes toys that use adhesives to prevent separation, and toys that are assembled using fittings or magnets without using adhesives. There is a toy that works.

Recently, toys have been developed that use magnets together with or separately from the fitting method to keep each part firmly coupled.

Here, there are several problems with conventional assembly toys.

First, in the past, parts were joined by magnets, so there was a problem in that assembly was not possible if the poles of the magnets did not match. Of course, to solve this problem, one side can be made of a magnet and the other side can be made of metal, but in this case, there is a problem in that the freedom of assembly is reduced because the metal parts are always combined with the magnet parts.

In addition, the axial bonding force between magnets or between a magnet and a metal may be strong to some extent, but the bonding force in the direction perpendicular to it is relatively weak and easily slips, making it difficult to maintain a constant angle between parts and thus causing various problems in the assembled state. There was a problem that it was difficult to transform.

In other words, in some cases, the coupling between the two parts needs to be achieved at various angles depending on the intention of the user, the child, and once assembled, it is necessary to maintain the coupling angle to some extent. To satisfy these conditions at the same time. There were some difficult aspects.

Accordingly, the present inventor (applicant)'s Korean Patent No. 10-1140326 discloses an assembly for selectively combining parts of a toy composed of a plurality of parts combined with each other, and more specifically, in FIG. 1 As shown, it includes a housing with an installation space formed inside, and a coupling block provided with a plurality of cantilever-shaped coupling pieces that are rotatably inserted into the installation space and at least a portion of which protrudes to the outside of the installation space, At one end of each coupling piece, a coupling head is provided to protrude, narrowing the space between two adjacent coupling pieces, and the parts are assembled through elastic deformation of the coupling pieces of the assembly assembly without using magnets, making it relatively safe for infants. We have created an “assembly assembly and an assembly toy using the same” that can provide toys and also reduce the manufacturing cost of the assembly assembly by omitting magnetic parts.

However, the two parts are assembled by the relative assembly assembly by engaging each other according to the curved shape of the outer surface of the coupling head while the coupling pieces of the assembly assembly installed on the two parts are offset at an angle of 90 degrees. In order to increase the axial coupling force of the assembly, the assembly tolerance must be kept to a minimum when the mating heads of the mating assembly are engaged. The smaller the assembly tolerance, the stronger force must be applied to engage the coupling heads of the state assembly, so children can use the assembly assembly. As a result, there is a problem in that it becomes difficult to assemble and separate the parts, and when the assembly tolerance is increased, the axial coupling force of the coupling head of the opposing assembly assembly decreases, resulting in a problem that the two assembled parts are easily separated.

Therefore, there is a demand for the development of assembled products that can be easily assembled and separated without applying force using magnets, and at the same time can be rotated at regular angular intervals in the assembled state by magnets.

The present invention allows for easy assembly and separation of multiple products using magnets, maintains vertical bonding force by block bonding the assembled joint surfaces, and maintains a constant angular gap when the two products are assembled by magnets.

The housing 10 is a component that forms the exterior and framework of the assembly assembly disclosed in the present invention, and may be formed in a cylindrical shape with a hollow 11 formed therein. When the assembly assembly is then coupled to the toy T, the housing 10 An installation space (A) corresponding to the outer peripheral surface of (10) is formed in the toy (T).

In addition, the housing 10 may further include a magnet holder 20 inserted into the internal hollow 11. The outer peripheral surface of the magnet holder 20 is formed to correspond to the inner peripheral surface of the hollow 11 of the housing 10, allowing the user to easily insert and remove the magnetic holder 20.

One end of the magnet holder 20 is formed with an uneven surface 21 so that the uneven surfaces 21 are attached and coupled to each other when combined with another assembly assembly, and the other end is formed in an open shape and has a receiving part 23 inside. is formed, and a magnet 30 to be described later can be inserted into this receiving portion 23.

The magnet 30 may be of a size that can be inserted into the receiving portion 23 of the magnet holder 20. Preferably, a cylindrical neodymium magnet is inserted into the receiving portion 23 of the magnet holder 20. Thus, a pair of assembled assemblies can be coupled to each other by abutting one end of the housing 10 on which the gear 13 is formed by the repulsive force of the magnet.

Next, a cover 40 may be installed to prevent the magnet 30 from being separated while closing the other end of the housing 10. The cover 40 may be formed in a lid shape to be detachably coupled to the other end of the housing 10 in order to close the other end of the hollow 11, and may be made of rubber or silicone to facilitate attachment and detachment. It may be made of material.

According to a preferred feature of the present invention, the concavo-convex surface 21 is formed in a block shape in which protrusions 220 and inlet portions 230 are intersected, and a pair of the housings 10 are connected to the magnet 30. When one end of the housing 10 on which the gear 13 is formed by magnetic force is coupled to each other so as to face each other, the uneven surfaces 21 of the magnet holder 20 engage with each other and are block-coupled.

The assembly process disclosed in the present invention, or more precisely, the process in which a pair of assembly assemblies are coupled to each other by the repulsive force of the magnet 30, is described as follows.

First, a gear 13 is formed around one end of the housing 10, and when a pair of housings 10 are brought close to each other by a magnet, the gears 13 mesh with each other and the housings 10 are coupled to each other.

Here, the uneven surface 21 of the magnet holder 20 is formed toward one end of the housing 10 where the gear 13 is formed. The uneven surface 21 has a protruding protrusion 220 and a recessed inlet ( 230) are arranged according to certain rules. Here, the protruding portion 220 and the recessed portion 230 may be arranged to intersect according to a specific rule as shown in FIG. 3 or 4, but are not limited to this and may be irregularities in which the protruding area and the recessed area are repeatedly formed. Any shape is possible as long as it has sides.

When one end of the housing 10 on which the gear 13 is formed by the magnetic force of the magnet 30 is coupled to each other so as to face each other, the concavo-convex surfaces 21 of the magnet holder 20 can be block-coupled by engaging each other. For more details, In other words, the protrusion 220 of the uneven surface 21 formed in one housing 10 is inserted into the inlet part 230 of the uneven surface 21 formed in another housing 10 facing the other housing 10 and is block-coupled, creating a vertical coupling force. can satisfy.

In addition, in a state where a pair of the housings 10 are coupled to each other and the uneven surface 21 of the magnet holder 20 is block-coupled, the teeth of the opposing gears 13 are engaged so that the gears 13 ) rotates, the housing 10 rotates by a unit length along the circumferential direction. As described above, when the opposing uneven surfaces 21 of a pair of housings 10 are block-coupled, the teeth of the gears 13 formed on one end of the housing 10 engage, thereby adding vertical coupling force. , the housing 10 is rotatable by gear action.

Accordingly, the user can rotate the toy by a unit length in the circumferential direction (or by the length of the teeth) by rotating the gear 13 while the pair of toys on which the housing 10 is installed are coupled to each other, regardless of direction. It can also be rotated 360°.

According to a preferred feature of the present invention, the uneven surface 21 includes a plate 210 formed in the center, a plurality of protrusions 220 arranged side by side at a predetermined distance along the circumference of the plate 210, and It is formed along the circumference of the plate 210 and includes a plurality of inlet portions 230 arranged to intersect between the plurality of protrusions 220.

As an example of the shape of the uneven surface 21, a disk-shaped plate 210 having a predetermined thickness is formed while sharing the same axis with the hollow 11, and is formed in a circumferential direction around the plate 210. A plurality of protrusions 220 protruding along the circumference may be arranged side by side and spaced apart by a certain circumferential distance. In addition, a plurality of inlet portions 230 are arranged side by side between the plurality of protrusions 220 and the protrusions 220 and inlet portions 230 are arranged to intersect.

Due to the shape of the protrusions 220 and the inlet 230 arranged in this way, when the pair of uneven surfaces 21 are attached to each other, the protrusion 220 and the inlet 230 are block coupled to achieve stable vertical coupling. It can be rotated freely by the gear 13 in the block-coupled state.

In another embodiment of the concavo-convex surface 21, the inlet portion 230 may be formed as a through hole open up and down. More specifically, while the above-described inlet portion 230 is disposed between the plurality of protrusions 220 and forms a closed surface recessed into the interior, in another embodiment, it may be formed as a through hole formed therethrough.

Accordingly, the protrusion 220 of the concavo-convex surface 21 facing the through hole is inserted into the through hole to form a block combination, and even if the protruding height of the protrusion 220 is slightly increased, the block can be combined without a step. There is an advantage in that it can be done.

According to a preferred feature of the present invention, a locking protrusion is formed extending from one end of the housing 10 where the gear 11 is formed toward the hollow 11 to prevent the magnet holder 20 from being separated from one end of the housing 10. It is characterized by further including (15).

The locking protrusion 15 is formed on the opposite side of the gear 13 at one end of the housing 10, extends a certain width toward the central axis of the hollow 11, and extends through the hollow 11 of the housing 10. It serves as a step to prevent the inserted magnet holder 20 from coming off.

In addition, the magnet holder ( A second step 250 extending from the outer peripheral surface of 20) may be formed.

The first step 240 is configured to be exposed to the outside of the housing 10 together with the protrusion 220 and the inlet portion 230 when the magnet holder 20 is inserted to the end of the housing 10, and the magnet The second step 250, which extends along the outer peripheral surface of the holder 20 and forms a step with the first step 240, comes into contact with the locking step 15 of the housing 10, causing the magnet holder 20 to separate. can be prevented.

According to a preferred feature of the present invention, the housing 10 on which the gear 13 is formed further includes a flange 17 formed along the outer peripheral surface of one end.

The flange 17 may be formed to have a predetermined height along the outer peripheral surface of one end of the housing 10, and is preferably not formed in a ring type along the entire outer peripheral surface, but rather has a plurality of pieces of the flange 17 at a certain level. It may be divided and formed at intervals. The flange 17 formed in this way is formed to protrude radially from the outer peripheral surface of the housing 10, and then as the housing 10 is inserted into the installation space A of the toy T, the flange 17 is within the installation space A. It plays a role of stable support.

In addition, the binding protrusion 19, which is formed between the split flanges 17 and extends radially from the middle area of the outer peripheral surface of the housing 10, is attached to the housing 10 in the installation space A of the toy T. It can act as a step to prevent it from easily coming off when inserted. Here, the binding protrusion 19 forms a horizontal surface protruding toward one end of the housing 10 and an inclined surface toward the other end, so that the housing 10 is easy to attach to the installation space A, but difficult to remove. It is desirable that this be accomplished.

According to a preferred feature of the present invention, the magnet holder 20 is formed with an accommodating part 23 inside which the magnet 30 can be accommodated, and the magnet 30 rotates within the accommodating part 23. And it is characterized by having a larger accommodating space than the magnet to enable movement.

The receiving part 23 is a space in which the magnet 30 can be accommodated, and is configured to correspond to the internal space of the magnet holder 20, where the upper part is closed with the uneven surface 21 and the lower part is open. The receiving portion 23 may have an inner circumferential surface corresponding to the shape of the magnet 30, preferably a cylindrical neodymium magnet.

In addition, the accommodating part 23 may have sufficient space to move or rotate by magnetic force while the magnet 30 is accommodated, and the inside of the magnet holder 20 can be moved through the accommodating space larger than the magnet 30. It has a higher degree of freedom than the fully adhered state, making it easy to finely adjust the position or fastening position of the concave-convex surface 21 that is block-joined.

According to a preferred feature of the present invention, in order to easily detach the cover 40 from the housing 10, a cut surface 41 is formed on one side of the cover 40.

The cover 40 can serve as a lid that closes the lower part of the housing 10 and prevents the magnet 30 from leaving. If necessary, the cover 40 can be easily attached and detached to replace the magnet. By forming a cutting surface 41 on one side, the user can easily remove the cover 40 from the housing 10 using the cutting surface 41.
