Description

Magnetic block for robot toy {Magnetic block for robot toy}

The present invention relates to a magnet block for a robot toy, and more particularly, to a magnet block for a robot toy that allows coupling between blocks and prevents a combined block from rotating easily without a separate connecting pin.

Block Toys is a playground equipment that assembles blocks of various sizes with a certain structure of joints and completes apparatuses and sculptures. It is also a teaching material that helps children to improve their creativity. In these block toys, conventionally, the connecting pins are used to couple the blocks together. For example, a cross-shaped groove is formed in the block body, and a separate connecting pin is also formed in a cross shape so as to correspond to the cross-shaped groove. However, the connection pin is small in size and may cause a loss, and a dangerous situation may occur in which the child swallows and swallows it.

On the other hand, Korean Patent Laid-Open No. 10-2014-0126783, etc., discloses a prior art for a block toy.

The present invention has been conceived in order to solve the problems of the conventional art as described above, and it is an object of the present invention to provide a magnetic bearing device in which spherical magnets are disposed inside a block, So that the user can change the combination mode of the block by making it possible to rotate at a certain angle.

According to an aspect of the present invention, there is provided a magnet block comprising: a block body having a built-in magnet space and a coupling surface formed outside the magnet built-in space; A ball magnet located in the magnet built-in space; And a coupling protrusion provided on the block body coupling surface.

Here, the engaging projections are formed in such a manner that the valleys and the floor are repeated over 360 degrees on the circumference of the engaging surface, and the engaging faces of the block bodies face the engaging faces of the adjacent block bodies, And the valleys of the engaging projections provided on the respective block bodies are closely contacted with each other when they are coupled to each other by attraction between the magnets.

When one of the block bodies of the combined block bodies is rotated, the joining of the joining ridges of the joining ridges provided on each block body rotates while passing over the neighboring ridges and the floor, And a fricative sound is generated.

And a magnet supporting plate installed at the entrance of the magnet built-in space of the block body to prevent the ball magnet from escaping and to transmit the magnetic force of the ball magnet.

The magnet block according to the present invention has the following effects.

First, the blocks can be easily combined. The magnet block according to the present invention needs only to bring the surfaces of the blocks to be coupled into contact with each other. In other words, a magnet is built in each block, and the blocks are combined due to the attractive force between the magnets. Therefore, since it is not necessary to connect the blocks to each other with the connecting pins as in the conventional art, the blocks can be easily coupled with each other.

Second, there is no need to worry about losing the connecting pin. As described in the first effect, the magnet block according to the present invention is attracted by the attraction force between the magnets and not the connecting pin. Therefore, it is not necessary to check whether the connecting pin exists at the time of each connection, and there is no dangerous situation in which the infant plays with the block and swallows the connecting pin.

Third, it prevents unintentional joining forms from occurring. The magnet block has a built-in magnet inside the coupling surface of the block so that the coupling between the blocks is easy, but if there is no fixing means, the blocks may rotate in the coupled state due to external force. Thus, when joining blocks, it is likely that contradictory block joining with the original intention will continue. Accordingly, the magnetic block according to the present invention has a coupling protrusion formed on the coupling surface, and the coupling protrusions of the block coupling surface are engaged with each other to fit into each other. Accordingly, the block can be easily rotated by the user's intention without the block being easily rotated by the external force, so that the coupling between the blocks can be maintained in a desired shape.

Fourth, users can form various types of joins with various angle combinations. In the magnetic block according to the present invention, a plurality of circumferentially uniform protrusions are formed at all 360 degrees, so that the magnet block can be combined at various angles. Therefore, the user can create various shapes using blocks.

1 to 5, a magnet block for a robot toy according to the present invention (hereinafter referred to as a "magnet block") includes a block body 11, a ball magnet 13, a magnet support projection 14, A supporting plate 15, an engaging projection 16, a supporting plate supporting projection 17, and an engaging surface 18.

The block body 11 may be formed in various forms as a body of the block, but the present invention will be described with reference to a block having the shape of a dumbbell. A magnet built-in space 12 is formed in both sides of the block body 11 and a ball magnet 13 is embedded in the magnet built-in space 12. [ In addition to the ball magnet 13, the magnet supporting protrusion 14, the magnet supporting plate 15 and the supporting plate supporting protrusion 17 are built in the magnet built-in space 12.

The ball magnet 13 is located in the magnet built-in space 12 to provide the attraction force necessary for coupling, thereby enabling coupling between the blocks. The ball magnet 13 is made in a spherical shape and freely rotates in the magnet built-in space 12. [ In other words, the inside of the ball magnet 13 is divided into a region having a relatively N pole and a region having a S pole. When engaging the blocks, the N pole and the S pole must be in contact with each other, The position of the polarity region formed in the light source 13 must be changed from time to time. For example, when one block is intended to be coupled with another block, the ball magnet 13 located in the magnet built-in space 12 faces the region of the S pole in the direction of the coupling surface 18, If the ball magnet 13 located in the magnet built-in space 12 faces the region of the S pole in the direction of the coupling surface 18, one of the N magnet poles The ball magnet 13 will be rotated.

The above description of the ball magnet 13 will be described by assuming that the A block 20 and the B block 30 are coupled as shown in Fig. That is, the S pole region of the ball magnet 23 located at the A block 20 obliquely faces the coupling plane 28, and the S pole region of the ball magnet 33 located at the B block 30 is located at the coupling plane The attracting force between the ball magnets 23 and 33 will cause the N pole of the A block 20 to face the S pole of the B block 30, The ball magnet 23 of the A block 20 located at an oblique position rotates to face the N pole on the coupling surface 28 so that the S pole of the A block 20 and the N pole of the B block 30 The A block 20 and the B block 30 are coupled to each other. Accordingly, the rotation of the ball magnets 23 and 33 does not correspond to only one of the ball magnets 23 and 33 in the A block 20 and the B block 30 that are coupled to each other, The area of the polarity in which the ball magnets 23 and 33, which can be changed, rotates and faces the coupling surfaces 28 and 38 can be changed.

The magnet supporting protrusions 14 are provided in the magnet built-in space 12 to prevent the ball magnet 13 from deviating from the built-in magnet space 12 due to attraction between the ball magnets 13.

The magnet support plate 15 is provided in the magnet built-in space 12 like the magnet support protrusion 14 and its end is formed at the same height as the coupling protrusion 16 so as to be in contact with another block when engaged with the other block . The magnet support plate 15 prevents the ball magnet 13 from separating from the magnet built-in space 12 and at the same time transmits the magnetic field of the ball magnet 13 to the magnet support plate 15 of the other block to be coupled, So that the attraction force can be generated. The material of the magnet support plate 15 is made of a material such as an iron material, to which a magnetic field is transmitted.

The engaging projections 16 are formed on the engaging surface 18 in the circumferential direction at 360 degrees with the uneven protrusions provided along the periphery of the magnet supporting plate 15 and include the valleys 16a and the floor 16b. The valleys 16a and the floor 16b are formed two at 90 degrees when the engaging projections 16 are regarded as coordinate planes. These troughs 16a and 16b are similar to the corrugations, the protruded portions are called the floor 16b, and the recessed portions are called the troughs 16a. In other words, the coupling protrusion 16 according to the present invention is formed in a waveform-like shape as viewed from the side as shown in FIG. 2. The protruded portion of the coupling protrusion 16 is called a floor 16b, Is referred to as a valley 16a. A detailed description of this engaging projection 16 will be given later in the course of using the magnet block 10.

The support plate support protrusion 17 prevents the magnet support plate 15 from being detached from the inside of the block body 11.

The engaging surface 18 is a portion abutting against each other for engagement between the different magnet blocks 10 and the block body 11 is formed with two engaging surfaces 18 at both ends thereof.

Hereinafter, the magnet block according to the embodiment of the present invention will be described in further detail with reference to the use process.

FIG. 6 is a view sequentially showing a state where the combined magnet block is rotated at a predetermined angle according to an embodiment of the present invention. FIG. 7 is a cross- FIG. 8 is a view illustrating an example in which a robot-shaped toy assembly is completed using a magnet block according to an embodiment of the present invention.

As shown in FIG. 6, the user joins the blocks by bringing the coupling surfaces 28, 38 of the A block 20 and the B block 30 into contact with each other. The magnet supporting plates 24 and 34 provided on the coupling surfaces 28 and 38 of the A block 20 and the B block 30 and the coupling protrusions 25 and 35 formed along the periphery of the magnet supporting plates 24 and 34 The magnet support plates 24 and 34 are formed by the S and N poles of the ball magnets 23 and 33 incorporated in the respective magnet built-in spaces 22 and 32 or the attraction generated by the N and S poles So that the A block 20 and the B block 30 are combined. The valleys 26a and 36b and the valleys 26b and 36b are formed on the coupling protrusions 25 and 35 so that the valleys 26a of the A block 20 are fitted in the valley 37b of the B block 30 And the floor 26b of the A block 20 is fitted into the valley 36a of the B block 30. [ This initial coupling state is shown in Fig. 6 (a).

If the user subsequently wants to change the join type of the block, it will rotate the block. That is, as shown in (b) of FIG. 6, the A block 20 may be rotated 45 degrees to change the coupling type of the block. Since the valley 26a of the coupling protrusion 26 of the A block 20 is coupled with the valley 36b of the B block 30 and the valley 26b is coupled with the valley 36a of the B block 30, The fact that the block 20 rotates means that the valley 26a of the A block 20 and the floor 26b are joined corresponding to the floor 36b and the valley 36a of the B block 30 located at the next 45 ° it means.

In the present invention, when the coupling protrusions 16 are considered to be the coordinate plane, since two troughs 16a and two floors 16b are formed on the ninety degrees, the number of troughs 16a corresponding to one floor 16b The valley 16a must rotate 45 degrees to engage corresponding to the next floor 16b. The rotation of such a block can be perceived by the tactile and auditory sense.

In other words, when the block is rotated, a "perfect" fricative is generated in the block, and a feeling that the block is rotating is conveyed to the user's hand. 7, after the coupling between the A block 20 and the B block 30 is released due to the force applied by the user, it is transferred to the next valleys 26a, 36a and the floor 26b, 36b It is a fricative sound generated by being pulled strongly by magnetic force. Therefore, the block does not easily rotate to the external force but maintains the coupling shape, and the user can recognize the rotation while rotating only when desired. Of course, it is also possible for the user to combine the A block 20 and the B block 30 with the initial coupling rotated at 45 degrees. That is, the user can rotate the block as many times as desired after combining the blocks, or can select the two cases in which the block is rotated in the predetermined angle beforehand.

FIG. 6C is a diagram showing a state in which the A block 20 is further rotated by 45 degrees in FIG. 6B. As shown in FIG. 6, the magnet block 10 according to the present invention allows the user to join the blocks and rotate them in the desired combination. In addition, since the magnet block 10 has not only a linear shape but also a curved shape, the user can appropriately use the desired block to finally manufacture the toy. For example, as shown in FIG. 7, various types of blocks may be used to manufacture a robot-shaped toy, or various other animal shapes or objects may be produced.

As described in detail above, the magnet block for a robot toy according to the embodiment of the present invention can easily join the block. The magnet block according to the present invention needs only to bring the surfaces of the blocks to be coupled into contact with each other. In other words, a magnet is built in each block, and the blocks are combined due to the attractive force between the magnets. Therefore, since it is not necessary to connect the blocks to each other with the connecting pins as in the conventional art, the blocks can be easily coupled with each other.

In addition, there is no need to worry about loss of the connecting pin. As described in the first effect, the magnet block according to the present invention is attracted by the attraction force between the magnets and not the connecting pin. Therefore, it is not necessary to check whether the connecting pin exists at the time of each connection, and there is no dangerous situation in which the infant plays with the block and swallows the connecting pin.

Also, it prevents unintentional joining forms from occurring. The magnet block has a built-in magnet inside the coupling surface 19 of the block so that coupling between the blocks is easy. However, if there is no separate fixing means, the blocks may rotate in a coupled state due to external force. Thus, when joining blocks, it is likely that contradictory block joining with the original intention will continue. Therefore, the magnetic block according to the present invention has the coupling protrusion 15 formed on the coupling surface 19, and the coupling protrusions 15 of the coupling surface 19 of the block are engaged with each other to fit into each other. Accordingly, the block can be easily rotated by the user's intention without the block being easily rotated by the external force, so that the coupling between the blocks can be maintained in a desired shape.

However, if the surface of the N-pole and the S-pole is changed when the ball magnet rotates freely in the magnet built-in space and is coupled with another block, the ball magnet according to the embodiment of the present invention Magnets are also possible.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, And additions should be considered as falling within the scope of the claims of the present invention.
