DETAILED DESCRIPTION OF THE INVENTION

Example 1

[0053] A block 1 according to example 1 will be described with reference to FIGS. 1 and 2. This block is for creating a straight track, characterized by being capable of creating a straight track in both a lateral direction and a longitudinal direction. The block is also used to create a cross-shaped track such as shown in FIG. 4. In such cases, the block can serve as an intersection for a block 3 for a straight line in a lateral direction and a block 33 for a straight line in a longitudinal direction.

[0054] The block 1 is formed from four parts. Specifically, these are a lower half 10 and an upper half 13 each half the size of the block 1, frames 17 interposed therebetween for creating recessed parts 101 to be described below, and a magnetic plate 2 attached to the upper surface of the upper half 13.

[0055] Lower-half projecting parts 11, 11 and lower-half windows 12, 12 are provided clockwise around the four sides of the lower half 10. Upper-half projecting parts 14, 14 and upper-half windows 15, 15 are provided clockwise around the four sides of the upper half 13. The lower half 10 and the upper half 13 are combined to obtain a single block shape; at this time, the lower-half projecting parts 11 and the upper-half projecting parts 14 join at each of two locations to form projecting parts 100. The frames 17 are inserted at the locations where the lower-half windows 12 and the upper-half windows 15 join to form recessed parts 101. Latch projections 18 at the four corners of the frames 17 latch onto the insides of the lower-half windows 12 and the upper-half windows 15.

[0056] A cross-shaped groove 16 is formed in the upper surface of the upper half 13. The cross-shaped magnetic plate 2 is set in the groove 16 and bonded in place, thereby firmly anchoring the magnetic plate 2 in the groove 16. Because the depth of the groove 16 is greater than the thickness of the magnetic plate 2, the magnetic plate 2 is sunk below the surface, thereby creating step parts that enable a mobile object, such as a magnetic wheel, to resist derailment when traveling through the cross-shaped groove. The step parts are not essential because, for example, a feature such as a guard rail may also be used. Easy-to-handle sheet iron was used for the magnetic plate 2. The movement of the mobile object will be described below.

[0057] A plurality of blocks 1 thus formed from four parts is connected in the same direction to obtain a straight track not shown in the drawings. While one of the parts in this example is the frame 17 for forming the recessed part 101, a frame for forming the projecting part 100 can be separately set as a part. Moreover, while a lower half 10 and an upper half 13 are combined to obtain a single block in this example, a design is also possible in which a right half and a left half are combined to form a single block. Alternatively, synthetic resin can be insert-molded using the magnetic element as an insert to obtain an integrally molded block constituted by a single mass. In this way, the block comprising the magnetic element can have any desired design.

Example 2

[0058] A block 3 according to example 2 will be described with reference to FIG. 3(A). This is used to build a track such as shown in FIG. 4, and is one block forming the lateral straight section in FIG. 4. The configuration of block 3 substantially mimics that of block 1 from example 1 described above, with projecting parts 30, 30 and recessed parts 31, 31 being provided clockwise around the four sides thereof; however, there are slight differences in the shape of the magnetic plate 20 and the shape of the groove 32 into which the plate is set.

[0059] Specifically, the groove 32 is formed in a lateral direction, and the straight magnetic plate 20 is set and anchored in a lateral orientation. The groove 32 is designed to have a depth that is greater than the thickness of the magnetic plate 20 so that the magnetic plate 20 is sunk below the surface, thereby forming step parts that enable a magnetic wheel or other mobile object to resist derailment when traveling therethrough.

Example 3

[0060] A block 33 according to example 3 will be described with reference to FIG. 3(B). This is used to build a track such as shown in FIG. 4, and is one block forming the longitudinal straight section in FIG. 4. The configuration of block 33 substantially mimics that of block 1 from example 1 described above, with projecting parts 34, 34 and recessed parts 35, 35 being provided clockwise around the four sides thereof; however, there are slight differences in the shape of the magnetic plate 21 and the shape of the groove 36 into which the plate is set.

[0061] Specifically, the groove 36 is formed in a longitudinal direction, and the straight magnetic plate 21 is set and anchored in a longitudinal orientation. The groove 36 is designed to have a depth that is greater than the thickness of the magnetic plate 21 so that the magnetic plate 21 is sunk below the surface, thereby forming step parts that enable a magnetic wheel or other mobile object to resist derailment when traveling therethrough.

[0062] A use state in which examples 1-3 are used will be described with reference to FIG. 4. Using a plurality of blocks 3 from example 2, the projecting parts 30 can be fitted into the recessed parts 31 of adjacent blocks 3 to form a lateral straight line. Using a plurality of blocks 33 from example 3, moreover, the projecting parts 34 can be fitted into the recessed parts 35 of adjacent blocks 33 to form a longitudinal straight line. The block 1 of example 1 is used to create an intersection between these two longitudinal and lateral straight lines. The projecting parts 100 of block 1 are connectable to both the recessed parts 31 of block 3 and the recessed parts 35 of block 33, and the recessed parts 101 of block 1 are connectable to both the projecting parts 100 of block 3 and the projecting parts 34 of block 33. In this way, the positions and number of intersections can be freely altered as desired by the user.

[0063] While block 1, block 3, and block 33 are placed directly on a floor or the like and combined in the example use described above, one might also wish to stack the blocks to construct a three-dimensional track. In such cases, blocks provided in advance with recessed parts or projecting parts, according to the form of the underlying block, on the bottoms of the block as well may be used. The design of such blocks is also a matter that can be addressed as desired. The important thing is that a track be constructible using the magnetic-element-comprising blocks of the present invention.

[0064] The block 120 not comprising a magnetic plate in FIG. 5 will be described as an example of the abovementioned underlying block. A projecting part 121, a recessed part 122, a recessed part 121, and a recessed part 122 are provided in clockwise order around the four sides of this block. A projecting part 123 is provided on the upper surface, and a recessed part 124 is provided in the undersurface. However, the block is a conventional “plain” block not comprising a magnetic plate.

Example 4

[0065] A block 4 according to example 4 will be described with reference to FIG. 6. This block can be used to create, for example, a track that transitions downward from a horizontal track, or a track that transitions from a vertical ascending track to a horizontal track, then downward from there. It can also be combined with the block according to example 5 in FIG. 7 described below to create a track having more variation in altitude.

[0066] Block 4 comprises three faces: a side face that comprises a projecting part 40, a face orthogonal thereto that comprises a recessed part 41, and an arc-shaped face on which an outward-curving magnetic plate 22 is set in a groove 42. In other words, the block comprise one projecting part 40 and one recessed part 41 apiece. The depth of the groove 42 is greater than the thickness of the magnetic plate 22, causing the magnetic plate 22 to be sunk below the surface, and forming step parts. The block 4 may be combined, for example, with the block 1 of example 1, or with block 120, which does not comprise the magnetic plate and comprises three projecting parts 121, 121, 123 and three recessed parts 122, 122, 124, as a spacer.

Example 5

[0067] Next, a block 5 according to example 5 will be described with reference to FIG. 7. This block comprises three faces: an arc-shaped inner side face on which an inward-curving magnetic plate 23 is set in a groove 52, the opposite of block 4 according to example 4, and two faces on which a projecting part 50 and a recessed part 51 are disposed facing orthogonal directions on either side of the side face. Because the magnetic plate 23 is set into the arc-shaped inner side face and has a tighter curvature than the arc-shaped outer side face, block 5 is designed to have a greater total length than the block 4 of example 4 described above. In addition, the depth of the groove 52 is greater than the thickness of the magnetic plate 23, causing the magnetic plate 23 to be sunk below the surface, and forming step parts.

[0068] This block 5 can be used to create, for example, a track that transitions upward from a horizontal track, or a track that transitions from a vertical descending track to a horizontal track, then upward from there.

[0069] In addition, either block 4 or block 5 can be used in the illustrated orientations, in which case a mobile object such as a magnetic wheel can be made to travel a track along the magnetic plate 22 and magnetic plate 23, i.e., the side faces.

Example 6

[0070] Next, a block 6 according to example 6 will be described with reference to FIG. 8. Block 6 is a block for forming what is generally referred to as a curve. The overall shape substantially mimics that of example 5 described above, but with differences in the shape of the magnetic plate 23 and the position and shape of the groove 62 into which the plate is set.

[0071] Specifically, the groove 62 is on the upper surface of the block 6 and has a rightward-curving shape, and a rightward-curving magnetic plate 24 is set and anchored therein. As in the case of block 5 of example 5, the groove 62 is designed to have a depth that is greater than the thickness of the magnetic plate 24 so that the magnetic plate 24 is sunk below the surface, thereby forming step parts that enable a magnetic wheel or other mobile object to resist derailment when traveling therethrough.

[0072] The block may also be used with the face comprising the groove 62 facing to the side or downward, rather than the illustrated orientation. Having the face comprising the groove face downward allows the magnetic wheel or other mobile object to travel the track upside down. In practicality, it is preferable to also provide leftward-curving blocks.

Example 7

[0073] Next, an elongated block 7 according to example 7 will be described with reference to FIG. 9. This is an elongated block 7 for use when playing with an electric-motor-powered mobile object the body of which is provided with a magnetic wheel such as described above, wherein external electrical power is supplied to the electric motor. When connecting another block to this elongated block 7, the blocks must be linked so that each of magnetic plates 25, 26 described below are definitely, not just mostly, connected to magnetic plates of other blocks; the blocks may be designed accordingly

[0074] The elongated block 7, which has a lateral length equivalent to five of the cubical blocks represented by dotted lines on both ends, is characterized by comprising a projecting part 70 on a side face of the head of the block, and comprising a recessed part 71 to which the projecting part 70 of another block can be mated on a side face of the tail of the block. A straight platform 72 is formed on the upper surface of the elongated block 7, with a pair of elongated magnetic plates 25, 26 being provided on the upper surface of the platform 72 with a gap therebetween, and plug-in tabs both ends of which are folded downward at right angles (not shown in the drawings) are attached so as to plug into sockets 73 provided on the ends of the platform 72. The magnetic plates 25, 26 are provided with electrifiable lead lines that lead to a power source.

[0075] The depth of the groove 72 and the thickness of the magnetic plates 25, 26 are substantially identical; in example 7, guard rails 74 are provided along both sides of the elongated block 7 so that a magnetic wheel or other mobile object can resist derailment when traveling therethrough. However, the rails need only be tall enough to create very slight step parts.

[0076] Although it is not shown in the drawings, the mobile object used in this example, in which an electric motor is used as a power source, is provided with a pair of left and right conductive brushes that contact the magnetic plates 25, 26 as the mobile object moves to receive electrical power. Using an electric motor as a power source enables perpetual continuous operation.

[0077] As stated above that the elongated block 7 is five cubic blocks in length, allowing a single elongated block 7 to suffice when creating the lateral straight track shown in FIG. 4, whereas five of, for example, the blocks 3 of example 2 shown in FIG. 3(A) are necessary. In a sense, this contributes to reducing costs.

[0078] In this way, the two end blocks and one elongated track plate can be combined to obtain a new block comprising an elongated track plate. Although the elongated magnetic plate, unlike the magnetic plates of example 7, is not for supplying external electrical power to the electric motor, it may also be configured similarly.

[0079] An example of a configuration associated with the elongated block 7 will be described without reference to the drawings. This is for creating an elongated track like that of block 7 of example 7 described above; because of the configuration of the block, thinner pillars are provided rather than the cubic blocks represented by dotted lines on both ends. The projecting part 70 and recessed part 71 are formed on these pillars. This makes it possible to further reduce weight and cost.

[0080] Two examples of other configurations will be given. A straight groove is provided in the surface of a flat elongated track plate that is not block-shaped but has the length of five cubic blocks 5, and an elongated magnetic plate is bonded therein. Grooves into which anchoring projections provided on the tops of end blocks can be fit are provided on both sides of the rear face of the elongated track plate. The end blocks are cubic blocks, with projecting parts and recessed parts being provided clockwise around the four sides thereof. The abovementioned anchoring projections are on the upper parts thereof. In one example, the elongated track plate and the end blocks are configured to yield a flat surface with no step parts. In another example, the projecting part 70 and recessed part 71 of example 7 described above are formed on the upper surface of an elongated block having the length of five cubic blocks.

Example 8

[0081] FIG. 10 depicts a toy car 8 that can be used on various tracks, including the ones in the examples described thus far, as viewed from the side of a chassis 80 on the rear of the car.

[0082] Magnetic wheels 81 are attached to both ends of an axle 82 as front wheels of the chassis 80, and magnetic wheels 83 are attached to both ends of an axle 82 as rear wheels. Rubber O-rings 84 are fitted onto the centers of the magnetic wheels 83 constituting the rear wheels; these ensure that the wheels sufficiently grip the track. The magnetic wheels 81 and magnetic wheels 83 can be attracted to the magnetic elements such as the magnetic plate 2 and magnetic plates 20-26 described above as the car travels. A power switch 85 is provided on the front end of the chassis 80.

[0083] Although the interior of the car 8 is not shown in the drawings, the car 8 is an ordinary toy car powered by an electric motor that drives the axles 82, and is provided with a battery holder necessary for this, with the battery holder, the electric motor, and the power switch 85 being wired in series. When the power switch 85 is switched to on, the magnetic wheels 83 start to turn, and roll over the track formed by the blocks. The car is capable of traveling along the track without derailing, with the magnetic wheels 83 and magnetic wheels 81 being attracted to the magnetic elements of the blocks.

[0084] A body 86 is attached to the top of the chassis 80. The body 86 is shaped like an ordinary car, but may also be shaped like an animal or the like.

Example 9

[0085] Next, a car 87 according to this example will be described with reference to FIG. 11. This car is provided with two sets of front and rear magnetic wheels 9, each set comprising one pair of left and right wheels, in the center of the chassis 88. Rubber O-rings 90 are fitted onto the centers of the magnetic wheels 9; these ensure that the wheels sufficiently grip the track. The magnetic wheels 9 are attached to axles 91 provided on the chassis 88. A car-shaped body 89 is attached to the top of the chassis 88. The internal configuration of the car 87 mimics that of example 8 described above.

[0086] The car 87 of this example is capable of traveling along the track without derailing, with the magnetic wheels 9 in the center of the chassis 88 being attracted to the magnetic elements of the blocks.

Example 10

[0087] Next, a car 800 according to example 10 will be described with reference to FIG. 12. Synthetic resin wheels 802 are attached to both ends of axles 804 as front and rear wheels of the chassis 801, with magnets 803 indicated by dotted lines being set inside the wheels. In a sense, the magnets 803 are covered by the wheels 802, and are characterized by being attracted to the magnetic elements despite not touching them as the car travels.

[0088] The internal configuration of the car 800 mimics that of example 8 described above; however, power for this car 800 is transmitted to a magnetic wheel 92 provided in the center of the chassis 801. An axle 93 allows the magnetic wheel 92 to freely rotate. Reference number 85 indicates a power switch.

Example 11

[0089] A block 125 according to example 11 will now be described with reference to FIGS. 13-16. In example 1 described above, for example, the blocks 1 are joined by mating projecting parts 100 and recessed parts 101. While this arrangement is acceptable as far as it goes, the blocks could also be viewed as simply having been mated by being snapped together. Specifically, while the track will be stable if built on a flat location such as interior flooring, the weight of the blocks 1 could cause the projecting parts 100 and the recessed parts 101 to disconnect if a three-dimensional track is built. This can happen not only after the three-dimensional track has been built, but also in the middle of building the track. If this would be unacceptable, one could, for example, provide ridges on the projecting parts 100 and the recessed parts 101 to provide a sensation of locking into place, but a more thorough solution is desirable. Specifically, the next goal is to provide a block that has sufficient tensile strength and can easily be disconnected, as necessary.

[0090] To that end, example 11 comprises a magnetic plate 27 that is oriented in the same direction as the top surface and the bottom surface of the cubical block 125, with a cylindrical projecting member 127 being attached to a window 126 provided in the surface of one side in this direction, and a recessed member 133 being attached to a window 132 provided on the surface on the other side. Mating grooves 129 are formed at two rotationally symmetric positions on the outer wall of the projecting member 127 so as to leave end-reaching parts toward the opening of the cylinder. As such, the end-reaching parts form stoppers 130 to be described below, and steps 131 to be described below are formed on both sides of the mating grooves 129.

[0091] Meanwhile, resilient mating tabs 135 are formed at four rotationally symmetric positions on the inner wall of the recessed member 133—specifically, at locations that engage with the mating grooves 129, and mating projections 136 that project toward the mating grooves 129 are formed in the distal ends of the mating tabs 135. As such, to join two blocks 12 together, the positions of the mating tabs 135 and the mating grooves 129 are lined up, and the projecting member 127 is inserted into the recessed member 133. The mating projections 136 can utilize the resilience of the mating tabs 135 to surmount the stoppers 130 during the insertion process, but are configured so that the mating projections 136 catch upon the stoppers 130 and prevented from surmounting the stoppers 130 when, conversely, pulling force is applied to the blocks 125 to disconnect the blocks, or unintentionally applied.

[0092] The mating projections 136 are configured to be capable of surmounting those steps 131 to the sides of the mating grooves 129 that are in the twisting direction when the blocks are twisted to intentionally disconnect the blocks; as a result, the mating projections 136 bypass the stoppers 130 to disengage with the mating grooves 129, thereby disconnecting the blocks 125. The projecting member 127 and the recessed member 133 are both cylindrical in shape, and thus permit twisting.

[0093] Different structures are provided on the inner wall of the recessed member 133 and the outer wall of the projecting member 127. Specifically, projecting guides 134 with triangular apexes that project toward the opening of the cylinder are provided at four rotationally symmetric positions between the mating tabs 135 on the inner wall of the recessed member 133. Meanwhile, guide grooves 128 into which the projecting guides 134 can fit with some play therebetween are provided at four rotationally symmetric positions between the mating grooves 129 on the outer wall of the projecting member 127.

[0094] To intentionally disconnect the blocks 125, the blocks are twisted to cause the mating projections 136 to surmount the steps 131, as described above; it is at this time that the projecting guides 134 contact the guide grooves 128, which spread outward toward the opening of the projecting member 127, and are guided from there by the guide grooves 128 so that force acts in a direction such that the blocks 125 retreat from each other, thereby disconnecting the blocks. The structures of the guide grooves 128 and the projecting guides 134 are also effective when joining blocks 125. Specifically, the projecting guides 134 are guided by the guide grooves 128 during this process as well, thereby naturally aligning the mating grooves 129 and the mating tabs 135 and eliminating the need to devote attention thereto.

Example 12

[0095] Next, a programmed three-dimensional track according to example 12 will be described with reference to FIG. 17. A looping track has been constructed using blocks B1-B5 having different shapes and roles, and spacer S blocks. For convenience, “block B2” and “block B3” refer to front and rear sides of the same block. The blocks B1-B5 are color-coded, with block B1 being yellow, block B2 on the front side of one block is blue, block B3 on the rear side of the same block is green, block B4 is orange, and block B5 is red. The blocks S, which do not comprise magnetic plates 27, are spacers for lifting block B4 from the surface of a table.

[0096] Going counterclockwise from the right side of the yellow block B1 at the second from the right end, on which the projecting member 127 of said block B1 is present, the order of the blocks is yellow (B1), blue B2 (green B3 on rear side), orange (B4), red (B5), blue B2, 2×yellow (B1), orange (B4), an arch-shaped green B3 (blue B2 facing front), red (B5), 2×yellow (B1), 2×orange (B4), 2×green B3, yellow (B1), blue B2, 2×yellow (B1), blue B2, and 6×yellow (B1), then connecting with the recessed member 133 of the block B1 at the starting point. A magnetic vehicle can repeatedly travel over the magnetic plates 27 on the loop track thus constructed.

[0097] While the linkage of blocks in the counterclockwise direction starting from the yellow block B1 at the starting point has been expressed in writing as above, it is also possible to record only the colors of the blocks. In other words, one may record yellow-blue-orange-red-blue-yellow-yellow-orange-green-green-red-yellow-yellow-orange-orange-green-green-yellow-blue-yellow-yellow-blue-yellow-yellow-yellow-yellow-yellow-yellow (going counterclockwise). The colors can be displayed in writing in this way, or, in the case of young children who haven't yet learned to read, displayed simply as colors using colored pencils or the like, or, for example, by putting colored stickers on a sheet. This is the “programming” referred to in the present invention.

[0098] This track programming can also be performed by envisioning the track in one's mind before combining the blocks. One can also refer to a program for a previously assembled track to assemble the same track by oneself. This example of the present invention, in which programming can be performed by color in this way, is an educational toy for STEAM education for laying the foundations of thinking in children, and advantageously enables users, from young children to adults, to play together. Apart from color, the block elements can also be expressed using patterns, block silhouette, or the like; this is a design matter that may be addressed as desired.

[0099] The present invention is not limited to the examples described above, and may be modified in any way within the concept of the invention, i.e., a toy block in which a magnetic element is provided on a block-shaped element comprising projecting and recessed parts shaped so as to be capable of being joined together. For example, the shape of the blocks may be triangular prisms or cylinders. The elongated elements illustrated in FIG. 9 and thereafter can be used to form slopes, various kinds of spirals, jump ramps, and see-saws. Alternatively, a switch for switching the track of the mobile object in the same manner as model train tracks may be provided. It is also preferable to prepare accessory blocks for blocking the step parts or recessed parts of the blocks, and stabilizing grounding on the floor. These accessory blocks may, for example, be molded from slip-resistant synthetic rubber.

[0100] The blocks themselves may be made to serve as magnetic elements by forming the blocks from sheet iron to create blocks similar to tin toys. This would fall within the scope of comprising a magnetic element. The track portion may be set above the magnetic element by drawing tracks on the sheet iron blocks. In other words, the feature of forming the blocks from sheet iron to make the blocks themselves serve as magnetic elements is also within the scope of the present invention.

[0101] The mobile object comprising magnetic wheels need not necessarily have a power source, but can also be played with by manually pushing the mobile object to create momentum. While a toy car 8 powered by an electric motor was described in example 8, a car powered by a spring not shown in the drawings rather than an electric motor may be designed. If a spring is used, not only a key to wind up the spring, but also a switch to turn the object on and off, should be provided.

INDUSTRIAL APPLICABILITY

[0102] Using the toy block of the present invention, a track comprising magnetic plates can be connected in various shapes, or reconnected in different shapes. In this way, the track itself is also made to function as a creativity-fostering educational toy, thereby greatly contributing to industrial development. The blocks may be made of any material, such as synthetic resin; wood can be used to impart the superior properties of wooden toys such as building blocks, and also provide a route for making effective use of thinned timber.
