[0001]

[Technical field to which the invention belongs]

 The present invention relates to a magnet-containing block for teaching materials, which is suitable for stacking or arranging a plurality of blocks side by side.

[0002]

[Prior art]

 Conventionally, a plurality of blocks are often used as teaching materials such as arithmetic. The blocks for this teaching material are used, for example, in a stack of a plurality of blocks or side by side to educate the concept of number and quantity. In this use, there is a method in which a block having a magnet held inside is used on an iron plate in order to maintain the stacked or side-by-side state.

As shown in FIG. 6, a conventional teaching material block 20 holding magnets is provided with magnets 25 (permanent magnets, hereinafter referred to as permanent magnets) in a storage portion 22 of an outer case 21 in a state where magnetic force acts to the outside. Same as above) is stored and held. In this conventional magnet-containing block 20, the outer case 21 is provided so as to cover the magnet 25 surface in order to form various appearances on the block. Reference numerals 23 and 24 are partition walls provided at a lower portion and an upper portion of the outer case 21 and forming the storage portion 21. Reference numerals 26 and 27 denote engagement portions that integrate the lower portion and the upper portion of the outer case 21.

[0004]

[Problems to be solved by the invention]

 However, in the above-described conventional magnet-containing block 20, the magnets 25 of the adjacent blocks 20 are of the same polarity (N-pole) because the magnets 25 are held in a stable state in the storage portion 22 of the exterior case 21. (Or S pole), the blocks 20 repel each other. For this reason, in the stacked state, one of the blocks 20 is inverted as shown in FIG. 6, and when the block 20 is in the side-by-side state, as shown in FIG. Have the disadvantage of repelling each other. If rebound or reversal occurs between the blocks 20 in this way, it may take a long time to normally stack or obtain the side-by-side state of the plurality of blocks 20 or operate so that the stacked or side-by-side state is easily obtained. Becomes difficult. When such a conventional magnet-containing block 20 is used as a teaching material, related education cannot be easily and sufficiently performed.

[0005] Therefore, the present invention provides a teaching material magnet that enables a plurality of blocks to be stacked or placed side by side on a desk or on an iron plate without any trouble, thereby enabling related education to be performed easily and sufficiently. It was intended to provide a block containing the.

[0006]

[Means for Solving the Problems]

 In order to achieve the above-described object, the magnet-containing block for teaching materials according to the present invention is a magnet-containing block in which magnets are housed in an outer case in a state where magnetic force acts to the outside. The size and shape of the portion are formed so that the magnet can be inverted.

[0007] According to the teaching material magnet-containing block of the present invention described above, when the plurality of blocks are stacked or arranged side by side, when each magnet faces the same polarity in the adjacent block. However, only the magnet in either one of the blocks is inverted in the storage portion of the outer case, and the inversion operation of the magnet does not reach the outer case itself. For this reason, the initial state in which a plurality of blocks are stacked or arranged side by side is maintained as it is, and the attraction based on the magnetic force of the magnet acts between the blocks, so that the stacked or side-by-side state of the blocks is maintained.

When the plurality of blocks are stacked or arranged side by side on an iron plate, the entirety of the plurality of blocks is stabilized on the iron plate. In addition, when multiple blocks are stacked or arranged side by side on a surface such as a desk surface on which a magnetic attraction action by a magnet does not work, the attractive action is the strongest in the storage part of the outer case. Since the magnet is displaced to the position, the magnetic attraction exerts the strongest attraction. Therefore, the stacked or side-by-side state is sufficiently stabilized.

As described above, the teaching material magnet-containing block of the present invention in which such an action is exerted is configured such that the size and shape of the storage portion in the outer case can be reversed. It is obtained by being. In such a block configuration, the volume of the storage portion of the outer case is formed so that the magnet can be inverted with respect to the size of the magnet, and the shape of the storage portion allows the magnet to be inverted. It suffices if it is formed so as not to interfere.

[0010] As described above, the size and shape of the storage portion of the outer case and the size and shape of the stored magnet are correlated with each other and cannot be unconditionally determined. In addition, the inside of the outer case can be formed into various shapes such as a rectangular or circular flat surface by a partition wall, and the outer shape of the magnet can be a rectangular parallelepiped shape, disk shape, etc. Of various shapes.

Further, in the teaching material magnet-containing block of the present invention, it is sufficient if the above-described action of inverting the magnet to be housed is exhibited, so that the external shape of the outer case may be of various shapes. It can be. Therefore, the outer shape of the outer case that forms the outer shape of the block may be a rectangular parallelepiped shape or a cylindrical shape, or may have an uneven shape on the peripheral surface so that a plurality of blocks can be combined.

Also, the teaching material magnet-containing block of the present invention includes a case in which a space or / and a magnetic force shielding portion in which the magnetic force of the magnet to be housed does not act on the outside is provided on the side surface of the outer case. .

In the above-described block, the attractive force based on the magnetic force of the inverted magnet acts on the specific surface of the block, that is, the normal direction of the upper and lower surfaces of the block. For this reason, in the blocks having this configuration, when the blocks are particularly in the stacked state, mutual attraction acts between the adjacent blocks and the blocks are stabilized. Further, when the blocks are arranged side by side, the magnetic force of the stored magnet is blocked by the space in the block side portion and / or the magnetic shielding portion, so that the magnetic force of the magnet does not reach the outside. .

[0014] Such a space portion is provided in an outer case constituting the side surface portion of the block, and the space portion prevents the magnetic force of the magnet from spreading from the position of the magnet in the storage portion to the side surface of the block. Gaps are formed. Further, as the magnetic shielding portion, a special shielding member may be provided, or an engaging member may be provided.

[0015]

[Embodiment of the invention]

 Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows a magnet-containing block 1 for teaching materials according to an embodiment. This block 1 is a magnet-containing block in which a magnet 9 is housed in an outer case 2 in a state where a magnetic force acts to the outside. It is formed so that it is possible.

The outer case 2 is formed by integrating a case-like case lower part 2a and a case upper part 2b, each of which is open on one side, and has an outer shape of a rectangular parallelepiped. A partition wall 4 is provided in the case lower part 2a, and a partition wall 5 is provided in the case upper part 2b.

In the lower part 2a of the case, engaging portions 7 and 6 are respectively provided upright at the positions of the gap 8a between the side wall and the partition wall 4, and symmetrical at the four corners. An engagement recess 6 a is formed on the top surface of the engagement portion 6, and an engagement protrusion 7 a is formed on the engagement portion 7. Corresponding to these engaging portions 6 and 7, in the upper portion 2b of the case, the engaging portions 6 and 7 are located at the positions of the gaps 8b between the side walls and the partition wall 5 and symmetrically at the four corners. Each is erected. The lower case 2a and the upper case 2b are engaged with each other by fitting the engagement protrusions 7a of the engagement portions 7 into the corresponding engagement recesses 6a. 2 is obtained.

The magnet 9 is inserted and arranged in the partition wall 4 before the case lower part 2a and the case upper part 2b are engaged. Accordingly, the storage part 3 is formed in a state where the case lower part 2a and the case upper part 2b are integrated, and the storage part 3 is formed of the area divided by the partition walls 4 and 5, and the magnet 9 is disposed in the storage part 3. Will be. The space 8 is formed on the side surface of the outer case 2 by the gaps 8a and 8b.

In the teaching material magnet-containing block 1, the width and height of the storage section 3 are large enough to allow the magnet 9 to be inverted with respect to the diameter and thickness of the magnet 9. Therefore, as shown in FIG. 2, the lower block 1 arranged with the lower surface in contact with the desk surface 10 is stacked with the lower block 1 with the lower surface in contact with the upper surface of the block 1. When looked up, the magnet 9 of the upper block 1 and the magnet 9 of the subsequent block 1 are in a state where their magnetic forces act on each other.

As described above, the magnets 9 in the block 1 at the upper and lower positions are in a state where they are mutually subjected to the magnetic force. In this case, when the magnetic action of each magnet 9 faces the same polarity (N-pole or S-pole), they repel each other. Operate to reverse. As a result, the magnets 9 face each other with different polarities and are attracted to each other based on the respective attractive forces. At this time, the magnet 9 of the upper block is located at the lower wall position, while the magnet 9 of the lower block 1 is raised to the upper wall position, that is, the position where the strongest attractive force is exerted. Each magnet is displaced until.

In this way, in the upper and lower blocks 1, only the reversing displacement operation of only one of the magnets 9 occurs, and the operation of these magnets 9 does not reach each block 1. Therefore, each block 1 is initially stacked. The state is maintained. Further, the attraction action of the respective magnets 9 acts on each block 1, and the stacked state is maintained in a stable state.

Further, when a third other block 1 is stacked on the upper block 1, the displacement of each magnet 9 in the upper and lower blocks 1 remains unchanged, Attraction occurs between one magnet 8 and the magnet 9 of the other block 1. As a result, the stacked state of the other blocks 1 is also stabilized.

Next, FIG. 3 shows a case where an iron plate 11 is arranged on a desk surface 10 and two blocks 1 are stacked on the iron plate 11 in the same manner as described above. In this case, the lower block 1 is attached to the surface of the iron plate 11 by the attraction of the magnet 9. Therefore, the lower block 1 is stably mounted on the surface of the iron plate 11. In addition, at the time of stacking, the magnets 9 of the upper block 1 are inverted or not inverted in the storage portion 3 and an attractive action is generated between the magnets 9 of the lower block 1. Therefore, the stacked state of the upper block 1 with respect to the lower block 1 is maintained in a stable state. Such gravitational action similarly occurs for the other blocks 1 further stacked on the upper block 1.

Next, FIG. 4 shows a case where the two blocks 1 are arranged side by side on the desk surface 10. In this case, in the block 1, the width of the space 8 in the side portion is set so that the magnetic force of the magnet 9 of each block 1 does not act. Therefore, no attraction or repulsion by the magnet 9 occurs between the blocks 1. As a result, as in the case of the block having no magnet, the blocks 1 can be arranged side by side without any trouble. Although not shown, when the two blocks 1 are arranged side by side on the surface of the iron plate 11, as described above, an attractive action occurs between the iron plate 11 and the magnet 9 of each block 1, so that each block 1 1 is maintained on the surface of the iron plate 11 in a stable state.

Next, the teaching material magnet-containing block 12 shown in FIG. 5 has a magnet 19 provided in the storage portion 15 of the outer case 13. In this block 12, the magnetic width of the space 18 between the partition walls 16, 17 in the case lower part 13 a and the case upper part 13 b forming the storage part 15 and the side wall is extended by the magnetic force of the magnet 19 to the lateral outside. It is something that can be done. Further, the case lower part 13a and the case upper part 13b are integrated with each other by an engaging part 14 in which an edge is fitted.

The width of the storage part 15 is larger than that of the storage part 3 of the block 1, and accordingly, the magnet 19 is also larger than the magnet 9. The fact that 19 can be inverted in the storage section 15 is the same as in the case of the block 1. Therefore, in the block 12, as in the case of the block 1, an attractive force is exerted at the time of stacking based on the reversing operation of the magnets 19, and further, when the magnets 19 are arranged side by side, the magnets 19 are also applied to the side faces of the blocks 12. A gravitational action based on this occurs.

As a result, as shown in FIG. 5, between the two blocks 12 placed side by side on the desk surface 10, the attraction action of each magnet 19 is applied to the contact surface of each block 12. For this reason, on the desk surface 10, the blocks 12 are maintained side by side in a stabilized state.

[Effect of the invention]

 Since the present invention is configured as described above, the following effects can be obtained. The magnet-containing block for teaching materials of the present invention is a magnet-containing block in which magnets are housed in an outer case in a state where magnetic force acts to the outside, and the size and shape of the housing portion in the outer case are as described above. Since the magnets are formed so as to be able to be inverted, even when a plurality of blocks are stacked or arranged side by side, the blocks themselves do not repel or invert.

[0029] Therefore, it is possible to perform the usage suitable for the original purpose of the blocks without hindrance, and to apply the attractive force of the magnet between the adjacent blocks to stabilize the stacking and the side-by-side state of a plurality of blocks. Can be done. This allows the block to be used as a more advantageous teaching material compared to conventional products.
