Description

Lego block connecting device that can change the joining angle between the Lego blocks, and Lego block and lego block set employing the same {Apparatus for connecting lego blocks capable of changing assembled angle, and lego block and lego block set employing the same}

The present invention relates to a Lego block mainly used as a toy for children or infants, and more particularly, a connection device for connecting the Lego blocks to repeat the combination and disassembly between the Lego blocks, and Lego blocks and Lego blocks employing the same It's about a set.

Lego block sets are used to teach children and toddlers about play and creativity. The lego block set includes a plurality of lego blocks made of individual members having the same shape or different shapes, and each lego block has a structure that is joined by fitting with each other. These LEGO blocks can be combined with children and toddlers as they want to achieve the desired shape such as animals or objects, and can be creative education.

Typically, Lego blocks are provided with a coupling structure of various forms to enable mutual coupling and disassembly. The coupling structure between the most common lego blocks is typically configured to have a protrusion in one lego block and a recess in another lego block so that each lego block is joined by mutual fitting. The user can join the two lego blocks by fitting the protrusions and depressions.

However, the lego block of the concave-convex coupling method has a disadvantage in that it is difficult to freely change the coupling angle in the coupled state or it is difficult to maintain the set coupling angle after setting the coupling angle to a certain position. For this purpose, a coupling structure between lego blocks has been proposed to maintain the state of the changed coupling angle and to change the coupling angle even after the two lego blocks are combined in an uneven manner.

1 shows an example of a lego block having such a coupling structure. As shown, the first lego block 110 is provided with a connecting protrusion 112 and the second lego block 120 is provided with a connection hole (122). The connecting protrusion 112 is configured in the form of a bar having a square octagonal cross section, and the connecting hole 122 is configured in the form of a hole having a square cross section. At this time, the width of the connection protrusion 112 and the width of the connection hole 122 is configured to be substantially coincident, when the insertion protrusion 112 is inserted into the connection hole 122, the infant or child does not have a great effort by pressing The first lego block 110 and the second lego block 120 can be coupled to each other and in a coupled state is configured to be separated from each other by applying a predetermined force or more.

The combined state of FIG. 1 is shown in FIG. Since the connecting protrusion 112 of the first lego block 110 has a regular octagonal cross section and the connecting hole 122 of the second lego block 120 has a rectangular cross section, the connecting protrusion 122 is formed in the connecting hole 122. There is some free space for 112 to rotate. Therefore, when an external force is applied to the second lego block 120 to rotate 45 ° clockwise with respect to the first lego block 110, the state becomes as shown in FIG. 3. In this state, it is maintained by 45 degree rotation by the regular octagonal cross section of the connection protrusion 112. FIG. When it is rotated further by 45 ° by applying an external force again, the state becomes as shown in FIG. 4, and the two lego blocks 110 and 120 are maintained in this state.

According to such a structure, while being able to change the coupling angle between the Lego blocks (110, 120) by applying an external force, the state of the two Lego blocks (110, 120) is maintained at the changed angular position, so that a plurality of Lego blocks are sequentially It is possible to maintain the desired shape even when laminated by bonding.

However, recently, toys are mainly made of wood in order to protect infants and children from environmental hormones. However, the conventional structure has a disadvantage in that it is not suitable for making wood.

That is, as described above, in order to enable a change in the coupling angle, the coupling protrusion 112 rotates in the coupling hole 122 while being firm so that the coupling of the coupling protrusion 112 and the coupling hole 122 is not easily separated. It should be possible. Therefore, the outer shape of the connecting protrusion 112 and the connecting hole 122 should be somewhat deformed when applying a rotational force, and in order to be deformed in this way, the first lego block 110 and the second lego block 120 are temporarily elastic. It must be made of deformable plastic. In the case of wood, since there is no elastic force, it is difficult to temporarily change the external appearance due to external force, and thus it is impossible to manufacture the wood firmly and rotatably.

Therefore, by making the Lego blocks made of wood, there is a need for a method of protecting the health of children and infants while maintaining the bonding between the Lego blocks, and also to allow the change of the coupling angle and maintenance of the changed coupling angle.

Coupling member 300 is configured to have a circular cross-section is formed in a circular cross-section so as to correspond to the shape of the coupling hole (212) as a whole. When the coupling member 300 is inserted into the coupling hole 212, the coupling member 300 is firmly fitted to the coupling hole 212 so that the coupling member 300 is fixed so as not to be separated from the first lego block 210. .

6 is an enlarged view illustrating a connection hole 310 forming surface of the coupling member 300 of FIG. 5, and FIG. 7 is a cross-sectional view taken along line II ′ of FIG. 6. Coupling member 300 is formed with a connection hole 310 recessed along its longitudinal direction. The connection hole 310 has a cross section of a first polygon shape having a predetermined number of angles, and preferably, the first polygon is a square.

A connection groove 330 is formed on the bottom surface of the connection hole 310 of the coupling member 300 to fix the coupling member 400 in the connection hole 310 as described below. At this time, the connection groove 330 is configured such that the inlet is formed in a smaller size than the inside. Four incision lines 340 are formed radially on the bottom surface of the connection hole 310 formed at the connection groove 330 so as to extend laterally from the connection groove 330.

The receiving portion 350 in which the stopper protrusion 450 of the connecting member 400 is accommodated is formed in the peripheral portion of the inlet side 310 of the coupling member 300 as described below. The accommodating part 350 is formed by pulling out the inlet side (edge part in which the connection hole 310 was formed) of the connection hole 310 in diagonal direction. Accordingly, as shown in FIG. 7, the connection hole 310 has a shape of an extended hole so that the width of a portion where the receiving portion 350 is formed is wider than the overall width.

8 is a perspective view of the connection member 400 according to the present embodiment, FIG. 9 is a side view of FIG. 8, and FIG. 10 is a side view of FIG. 9 viewed from the II-II 'direction.

The connection member 400 is configured to have a bar shape as a whole, and is composed of two connection parts 410 provided at both end portions. Each connecting portion 410 has a cross-section of a second polygon consisting of a greater number of angles than the second polygon formed by the connection hole 310 formed in the coupling member 300, preferably, the second polygon is a regular octagon. The connecting member 400 is coupled to the coupling member 300 by fitting the connection portion 410 into the coupling hole 310 of the coupling member 300. The connecting portion 410 and the connecting hole 410 is configured to substantially match the width of the cross-section, when inserting the connecting portion 410 into the connecting hole 410 can be coupled to each other by indentation without great effort for children or children. While combined, they must be applied at least a certain amount of force so that they are separated from each other.

At both ends of the connection member 400, the connection protrusion 430 is formed to protrude. The connecting protrusion 430 is configured to have a shape that matches the shape of the connecting groove 330 formed in the coupling member 300, so that the connecting protrusion 430 is connected to the connecting groove 430 when the connecting portion 410 is inserted into the connecting hole 310. 330). At this time, the connection protrusion 430 is configured such that the end side is larger than the other portion, so that the connection groove 330 is configured to conform to the connection protrusion 430, accordingly, the connection projection 430 and the connection groove 330 ) Are configured to hook together. The incision line 340 formed around the connection groove 330 facilitates insertion coupling by functioning to substantially expand the inlet size of the connection groove 330 when the connection protrusion 430 is inserted into the connection groove 330. Function.

On the other hand, in the present embodiment has been illustrated that the coupling groove 330 is formed in the coupling member 300 and the connection protrusion 430 is formed in the connection member 400, on the contrary, the coupling protrusion is formed in the coupling member 300 And it is also possible to configure so that the connection groove is formed in the connecting member (400).

The stopper protrusion 450 is formed at the side surface of the connection member 400. Stopping protrusion 450 is composed of a prism-shaped rib formed on the octagonal outer peripheral surface of the connecting member 400, respectively. The stopping protrusion 450 functions to limit the depth of the connection member 400 inserted into the connection hole 310 to a predetermined depth, as described below.

FIG. 11 is a view illustrating a state in which the coupling member 300 of FIG. 7 and the connection member 400 of FIG. 10 are coupled to each other.

The connection member 400 and the coupling member 300 are coupled by inserting the connection portion 410 of the connection member 400 into the connection hole 310 of the coupling member 300. Cohesion is maintained enough to allow infants or children to separate by external force. In the combined state, the connecting protrusion 430 is inserted into the connecting groove 330 and hooked to be easily maintained so as not to fall out. In addition, the lower half of the stopping protrusion 450 is accommodated in the receiving portion 350 of the coupling member 300.

In FIG. 11, only one coupling member 300 is shown coupled to the bottom of the coupling member 400, but in order to interconnect two Lego blocks, an additional coupling member 300 is connected to the coupling member 400. It is also coupled to the upper connection portion 410.

12 illustrates a state in which the coupling member 300 is coupled to the two lego blocks 210 and 220, respectively, and connected to each other by the connection member 400. As shown in Figure 12, the second lego block 220 is also formed with a coupling hole 222 for coupling the coupling member 300. The coupling member 300 of the second lego block 220 is also maintained so as not to be easily pulled out by being coupled to the connection groove 330 of the connection member 400, the receiving portion 350 of the coupling member 300 The half of the stopper projection 450 of the coupling member 400 is received in). Accordingly, even if the stopping protrusion 450 protrudes from the side of the coupling member 400, the two lego blocks 210 and 220 are connected to face each other without being spaced apart from each other.

According to the present invention as described above has the following advantages.

First, since the connecting hole 310 of the coupling member 300 is composed of a regular octagonal shape and the outer circumferential surface of the connecting member 400 is composed of a square, the two lego blocks (210, 220) can be relatively rotatably coupled to each other. The state in which the rotation angle is changed by applying an external force as in the prior art is maintained. At this time, since the two lego blocks 210 and 220 are combined only by the two members 300 and 400, if only the connecting devices 300 and 400 are made of plastic, the two lego blocks 210 and 220 are made of wood. It is possible. Therefore, it is possible to manufacture toys that are environmentally friendly and can protect infants and children from environmental hormones.

Second, since the coupling member 300 and the connection member 400 is hooked by the connection groove 330 and the connection protrusion 430, the coupling force between the coupling member 300 and the connection member 400 is suitable for infants or children. It is easy to manufacture so that it is maintained. As described above, the connection member 400 and the coupling member 300 may be coupled and separated by an infant or child by magnetic force, but not too easily separated from each other. If the coupling structure of the connecting protrusion 430 and the connecting groove 330 does not exist, such as by precisely processing the size of the connection hole 310 of the coupling member 300 and the size of the connection portion 410 of the connection member 400 Since it is necessary to generate a bonding force requires a high mold precision, according to the present invention does not require such a high precision, it is easy to manufacture. Furthermore, the cutting line 340 formed around the connecting protrusion 430 makes it easy to insert and separate by external force while maintaining a strong bonding force.

Third, since the cross section of the coupling holes (212, 222) to be formed in the Lego blocks (210, 220) is circular, processing is easy. In the case of plastic material, the part is manufactured through a mold, so the shape of the hole formed in the part is not very limited. However, when the part is made of wood, it is difficult to form a square hole, for example, because a hole must be drilled. Entails. Therefore, when it is necessary to form a square connection hole 122, such as the connection hole 122 formed in the second lego block 120 of the prior art of Figure 1 it is very good to manufacture the lego block 120 from wood it's difficult. However, in the present invention, since the coupling holes 212 and 222 are circular, the formation of the coupling holes 212 and 222 becomes very easy even when the lego blocks 210 and 220 are made of wood.

Fourth, since the depth of the connection member 400 is inserted into the connection hole 310 is controlled by the stopper protrusion 450, even if a tolerance occurs in the depth of the connection hole 310, the coupling member 300 and the connection member ( It is possible to maintain a stable coupling relationship between the 300). Inevitably an error occurs in the cooling process after the production of the plastic part, the stopper projection 450 of the connection member 400 is the two coupling member 300 with both the connection portion 410 of the connection member 400 to an equal depth. This function limits the insertion depth to be inserted into the. Thus, for example, one end of the connection member 400 is inserted too deeply into any one of the coupling members 300, thereby preventing the other end from being inserted into the other coupling member 300. Furthermore, despite the presence of the stopping protrusion 450, the stopping protrusion 450 is accommodated by the accommodation unit 350, so that the separation between the two lego blocks 210 and 220 coupled thereto does not occur.

13 and 14 illustrate a second embodiment of the present invention, and show an example in which the coupling member is attached to the second lego block.

In the present embodiment, the coupling member 400a is mounted at one portion of the second lego block 720, and the binding member 400a is rotated by a pivot pin (not shown) on the second lego block 720. Possibly mounted. Accordingly, as shown in FIG. 13, the coupling member 400a is rotatable between the state protruding horizontally and the state rotated downward from the horizontal direction as shown in FIG. 14. According to such a structure, the second lego block 720 does not need to separately install the connecting member 300, and also by the rotation angle of the coupling member (400a) when the combination of the LEGO blocks and a variety of shapes when stacked It is possible to implement.

FIG. 15 illustrates a third embodiment of the present invention, and illustrates an example in which the coupling member 300 is mounted on the first lego block.

In the structure as described above, the coupling member 300a hardly needs to be separated after being coupled to the first lego block 710 once. Furthermore, since the coupling member 300a has a quadrangular connection hole, for example, when the first lego block 710 has a rectangular cross section as shown in FIG. 15, the quadrangular arrangement of the connection hole is a quadrangle of the first lego block 710. It is necessary to be combined to match the placement of the cross section. However, it may be difficult for a child or an infant to align the arrangement of the first lego block 710 and the coupling member 300a accurately. Therefore, as shown in FIG. 15, this difficulty can be solved by manufacturing one lego block in an assembled state in which the coupling member 300a is coupled to the first lego block 710. In the state of FIG. 15, the coupling member 300a may be strongly pressed into the first lego block 710 to be firmly coupled, or may be coupled through a separate adhesive.

FIG. 17 illustrates that the connecting member 400c has a T shape and three connecting parts are arranged. 18 illustrates that the connecting member 400d has a Y-shape and three connecting portions are disposed radially.

Through such various types of connection members, the number or coupling positions of the lego blocks that can be coupled using one connection member can be variously modified.

On the other hand, according to the present invention, as shown in Figure 15 includes a first lego block 710 is provided with a fixed coupling coupled member and a second lego block 720 is provided with a fixed coupling member It is possible to provide a set of lego blocks composed of various lego blocks and also includes other types of lego blocks.

Is formed. The connection groove 330a is formed to penetrate the plate surface of the bottom member 370.

In order for the bottom member 370 to be coupled to the rear surface of the coupling member 300a, the rear surface of the coupling member 300a (that is, the bottom surface of the connection hole of the coupling member) is manufactured as an open surface. At the same time as the bottom member 370 is inserted and received, a locking step shape receiving portion 321a is provided to prevent the bottom member 370 from being drawn in a predetermined depth or more. In addition, the length of the receiving portion 321a is configured to be larger than the thickness of the bottom member 370, the bottom member 370 is introduced into the receiving portion 321a more than a predetermined depth, as shown in Figure 21 In the state in which the connection member 400 is coupled to the coupling member 300a, there is a free space for the connection portion formed at the end of the connection member 400 to be inserted through the connection hole 330a of the coupling member 300a. do. As a result, the coupling member 300a and the coupling member 400 are unevenly coupled to each other.

On the other hand, the engaging portion (320a) protruding in the wedge shape from the outer peripheral surface is formed on the rear side of the coupling member (300a). As shown in FIG. 21, the stiffening part 320a maintains a firm coupling force to prevent the coupling member 300a from being separated again after the coupling member 300a is inserted into and coupled to the lego block 210 as shown in FIG. 21. do.
