Description

  The present invention relates to a toy having magnets, and more particularly to a toy including a traveling body including wheels.

Conventionally, as this kind of toy, for example, one described in Patent Document 1 (Japanese Patent Laid-Open No. 7-8640) is known. As shown in FIG. 15, this toy Ga includes a traveling body 100 in which a plurality of block bodies are connected via a magnet 115, and includes a wheel 110 that rotates to a lower block body. The wheel 110 is formed in a regular circle, and an axle 111 is provided at the center thereof. The axle 111 is fixed to the traveling body 100.
With the outer peripheral surface 112 of the wheel 110 in contact with the ground contact surface, for example, when human power is applied to the traveling body 100 and the traveling body 100 is pushed in a direction orthogonal to the axle 111, the wheel 110 rotates about the axle 111. To do.

Japanese Patent Laid-Open No. 7-8640

  However, in this conventional toy Ga, since the axle 111 is provided at the center of the wheel 110 and the axle 111 is fixed to the traveling body 100, the wheel 110 is uniform when the traveling body 100 travels. Since the wheel 110 rotates in a straight line, the movement of the wheel 110 is monotonous, and the traveling mode of the traveling body 100 is not interesting.

  The present invention has been made in view of such a problem, and an object of the present invention is to provide a toy that makes the traveling mode of the traveling body interesting by varying the movement of the wheels.

  In order to achieve such an object, a toy according to the present invention is a toy including a traveling body and a wheel that rotates on the outside of the traveling body, and the wheel is similar to the outer peripheral surface that contacts the ground surface and the outer peripheral surface. And a rolling element that rolls on the inner circumferential surface of the wheel body, and the wheel body is connected to the center of the rolling element and a perpendicular passing through the center. The distance h of the lower line connecting the lower point that intersects the outer peripheral surface that is in contact with the ground is always set to the same length, and the center of the rolling element and the vertical line passing through the center are opposite to the ground surface. When the distance of the upper line connecting the upper point intersecting the outer peripheral surface is H, it is formed so that H / h> 1, and the wheel is attached to the outer surface of the traveling body and rotated. A wheel holding portion for holding the wheel, the wheel holding portion of the traveling body and the rolling element, Are a combination of magnets between the combination or magnetically attracted to each other magnetically attached body magnetically attracted to the magnet.

  As a result, when the outer peripheral surface of the wheel is in contact with the ground contact surface, for example, by applying human power to the traveling body and pushing the traveling body in the rotation direction of the wheel, the rolling element rolls on the inner peripheral surface of the wheel body. Then the wheel rotates. Specifically, when the traveling body is pressed, the rolling element magnetized rotatably on the wheel holding portion of the traveling body moves in the same direction as the traveling body, and this movement causes the rolling body to move away from the wheel body. The wheel body is rotated by the friction force between the outer peripheral surface of the wheel body and the ground contact surface while rolling on the inner surface. At this time, the wheel body is formed such that the distance h of the lower line connecting the center of the rolling element and the lower point where the perpendicular passing through the center of the rolling element meets the outer peripheral surface that is in contact with the grounding surface is always the same length. As a result, the outer peripheral surface is always in contact with the grounding surface, so that the wheel can be rotated even if the distance H of the upper line is longer than the distance h of the lower line. Moreover, since H / h> 1, the center of the wheel body is shifted with respect to the axle (wheel holding portion), and therefore the wheel body rotates eccentrically, so that the movement of the wheel is various. Thus, the traveling mode of the traveling body becomes interesting. In this case, if the shape of the outer periphery of the wheel is formed not only in a circle but also in various shapes such as an ellipse, a triangle, a quadrangle, etc., it is possible to diversify the rotation mode of the wheel when the traveling body travels. It is possible to make the traveling mode of the traveling body interesting.

  In addition, since it is possible to run the traveling body by rotating the wheel regardless of the shape of the outer periphery of the wheel, when magnetizing a plurality of wheels on the traveling body, wheels having different outer peripheral shapes are used. The traveling body can be magnetized, and in this case, since the plurality of wheels have different rotational modes, the traveling mode of the traveling body can be more interesting. Furthermore, since the rolling element is magnetized and held on the wheel holding portion of the traveling body, the wheel can be easily attached to and detached from the traveling body, so that a plurality of wheels having different outer peripheral shapes can be magnetized. Even in the case of wheel replacement, the wheel can be easily replaced.

  And if necessary, the wheel body is configured so that the maximum value of H / h is H / h> 3. That is, all or part of the wheel body is formed so that H / h is H / h> 3. As a result, the difference between the length of the distance h of the lower line and the length of the distance H of the upper line becomes larger, and therefore the degree of eccentricity is further increased. Therefore, the rotation mode of the wheel when the traveling body travels is further increased. It can be even more interesting.

  Further, if necessary, the wheel body is composed of a pair of side plates sandwiching the rolling elements and an annular connecting member that houses the rolling elements and connects the pair of side plates, and the outer periphery of the side plates is the outer periphery. The inner surface of the connecting member is the inner peripheral surface. Thereby, since the rolling element comes to be accommodated in the space surrounded by the pair of side plates and the connecting member, it is possible to prevent the rolling element from slipping out of the wheel body. Rolls on the inner surface.

  Furthermore, it is set as the structure which formed the said rolling element in spherical shape or disk shape as needed. Thereby, it becomes easy for a rolling element to roll an internal peripheral surface.

  Furthermore, if necessary, the rolling element is formed into a spherical shape, and the wheel body is composed of a pair of side plates that sandwich the rolling element and a connecting member that houses the rolling elements and connects the pair of side plates. An opening in which the center of the rolling element is exposed is formed on at least one side of the pair of side plates, the outer periphery of the side plate is the outer peripheral surface, and the opening edge of the opening is the inner peripheral surface. Thereby, since the center of a rolling element comes to be exposed from a wheel main body, the magnetic adhesion property of a rolling element and the wheel holding part of a traveling body improves. In addition, since the opening edge of the opening is the inner peripheral surface, the connecting member may be formed in any way, and the appearance of the wheel body can be made interesting accordingly.

  Further, if necessary, the rolling element is formed of a disk, a shaft body is protruded from the center of the disk, the wheel body includes a pair of side plates sandwiching the rolling element, and the rolling element. And an annular connecting member for connecting and connecting the pair of side plates, forming an opening through which the shaft of the rolling element is exposed on at least one side of the pair of side plates, and setting the outer periphery of the side plate to the outer peripheral surface The inner surface of the connecting member is the inner peripheral surface. Thereby, since the shaft body of the rolling element is exposed from the wheel body, the magnetic adhesion between the rolling element and the wheel holding portion of the traveling body is improved.

  According to the toy of the present invention, when the traveling body is pushed in the rotation direction of the wheel, the rolling element that is rotatably magnetized around the wheel holding portion of the traveling body as an axle is provided on the inner peripheral surface of the wheel body. The rolling body moves in the same direction as the traveling body while rolling, and the rolling body rolls on the inner peripheral surface of the wheel main body by this movement, and the wheel main body rotates by the frictional force between the outer peripheral surface of the wheel main body and the ground contact surface. At this time, the wheel body is formed such that the distance h of the lower line connecting the center of the rolling element and the lower point where the perpendicular passing through the center of the rolling element meets the outer peripheral surface that is in contact with the grounding surface is always the same length. As a result, the outer peripheral surface is always in contact with the grounding surface, so that the wheel can be rotated even if the distance H of the upper line is longer than the distance h of the lower line. Moreover, since H / h> 1, the center of the wheel body is shifted with respect to the axle (wheel holding portion), and therefore the wheel body rotates eccentrically, so that the movement of the wheel is various. Thus, the traveling mode of the traveling body becomes interesting. In this case, by forming the shape of the outer periphery of the wheel in various shapes, it is possible to diversify the rotation mode of the wheel when the traveling body travels, and to make the traveling aspect of the traveling body interesting. it can.

  In addition, since it is possible to run the traveling body by rotating the wheel regardless of the shape of the outer periphery of the wheel, when magnetizing a plurality of wheels on the traveling body, wheels having different outer peripheral shapes are used. The traveling body can be magnetized, and in this case, since the plurality of wheels have different rotational modes, the traveling mode of the traveling body can be more interesting. Furthermore, since the rolling element is magnetized and held on the wheel holding portion of the traveling body, the wheel can be easily attached to and detached from the traveling body, so that a plurality of wheels having different outer peripheral shapes can be magnetized. Even in the case of wheel replacement, the wheel can be easily replaced.

Hereinafter, a toy G according to an embodiment of the present invention will be described with reference to the accompanying drawings.
1 to 5 show a toy G according to the first embodiment of the present invention. The toy G includes a traveling body 1 and wheels 10 that rotate to the outside of the traveling body 1.

  The traveling body 1 is formed of a wooden rectangular parallelepiped 1a. On the upper surface of the rectangular parallelepiped 1a, a wooden cube 1b having a pattern, engraving, or the like is provided. Moreover, the wooden cylinder 1c is provided in the end of the axial direction of the rectangular parallelepiped 1a.

  Further, the traveling body 1 is provided with a wheel holding portion 3 that is attached to the outer side surface 2 of the traveling body 1 and rotatably retains the wheel 10. The wheel holding unit 3 is composed of a magnet or a magnetized body that is magnetically attached to the magnet. In this Embodiment, the magnet is accommodated in the inside of the rectangular parallelepiped 1a and the cylinder 1c.

The wheel 10 includes a wheel main body 20 including an outer peripheral surface 21 that contacts the ground surface and an inner peripheral surface 22 similar to the outer peripheral surface 21, and a rolling element 30 that rolls on the inner peripheral surface 22 of the wheel main body 20. Configured.
In this Embodiment, the rolling element 30 is formed in the spherical shape, and is comprised by the magnetic attachment body magnetically attached to a magnet. In addition, you may comprise the rolling element 30 with a magnet.

The wheel body 20 includes a pair of side plates 23 that sandwich the rolling elements 30 and a connecting member 24 that houses the rolling elements 30 and connects the pair of side plates 23.
The side plate 23 is formed in a substantially elliptical shape, and an opening 32 through which the center 31 of the rolling element 30 is exposed is formed on at least one side of the pair of side plates 23. In the present embodiment, an opening 32 is formed in each of the pair of side plates 23. The outer periphery of the pair of side plates 23 is an outer peripheral surface 21, and the opening edge 32 a of the opening 32 is an inner peripheral surface 22. That is, the shape of the outer periphery and the shape of the opening edge 32a are formed in a similar shape. When the rolling element 30 is sandwiched between the pair of side plates 23, the center 31 of the rolling element 30 protrudes from the pair of side plates 23 and is exposed.
The connecting member 24 is formed in an annular shape using a plate-like member. The connecting member 24 is provided inside the outer periphery of the pair of side plates 23. The connecting member 24 may be provided along the outer periphery of the pair of side plates 23, and the outer periphery of the pair of side plates 23 and the outer surface of the connecting member 24 may be the outer peripheral surface 21.

  The wheel body 20 is formed such that the distance h of the lower side line connecting the center 31 of the rolling element 30 and the lower point 25 intersecting the outer peripheral surface 21 grounded to the ground surface is always the same length. In addition, when the distance of the upper line connecting the center 31 of the rolling element 30 and the upper point 26 where the perpendicular passing through the center 31 intersects the outer peripheral surface 21 opposite to the ground contact surface is H, H / h> 1 is formed. Desirably, the maximum value of H / h is formed so that H / h> 3.

Therefore, when the toy G according to the first embodiment is caused to travel, the following effect is obtained.
First, as shown in FIG. 1, the wheel 10 is brought into contact with the outer surface 2 of the traveling body 1 so that the axis 4 direction of the traveling body 1 and the rotation direction of the wheel 10 are parallel, and the rolling element 30 is held by the wheel. The part 3 is magnetized. At this time, of the pair of side plates 23, the side plate 23 in which the opening 32 is formed is positioned on the traveling body 1 side and magnetized. In the present embodiment, since the opening 32 is formed in each of the pair of side plates 23, either side plate 23 may be positioned on the traveling body 1 side. Since the center 31 of the rolling element 30 is exposed from the opening 32 of the side plate 23, the magnetic adhesion between the rolling element 30 and the wheel holding portion 3 is improved. The rolling element 30 is housed in a space surrounded by the pair of side plates 23 and the connecting member 24, and the center 31 of the rolling element 30 protrudes from the pair of side plates 23 and is exposed. Is brought into contact with the opening edge 32a of the opening 32 from the inside of the wheel main body 20, so that the rolling element 30 is prevented from coming out of the wheel main body 20.

  In this state, the outer peripheral surface 21 of the wheel 10 is grounded to the ground surface, and, for example, human power is applied to the traveling body 1 to push the traveling body 1 in the rotation direction of the wheel 10. When the traveling body 1 is pushed, as shown in FIG. 4, the rolling element 30 magnetized rotatably on the wheel holding portion 3 of the traveling body 1 as an axle is provided on the inner peripheral surface 22 of the wheel body 20. It moves in the same direction as the traveling body 1 while rolling. Since the rolling element 30 is formed in a spherical shape, it easily rolls on the inner peripheral surface 22. As the rolling element 30 moves, the rolling element 30 rolls on the inner peripheral surface 22 of the wheel main body 20, and the wheel main body 20 rotates by the frictional force between the outer peripheral surface 21 of the wheel main body 20 and the ground contact surface.

  At this time, the distance h of the lower line connecting the wheel body 20 to the lower point 25 intersecting the outer peripheral surface 21 where the perpendicular passing through the center 31 of the rolling element 30 and the center 31 of the rolling element 30 contacts the ground surface is always the same length. Since the outer peripheral surface 21 is always in contact with the grounding surface, the upper line distance H is longer than the lower line distance h. The wheel 10 can be rotated. In addition, since H / h> 1, the center of the wheel body 20 is displaced with respect to the axle (wheel holding portion), so that the wheel body 20 is rotated eccentrically. As a result, the traveling mode of the traveling body 1 becomes interesting. That is, the rotation of the wheel 10 starts from a state where the length of the distance H of the upper line as shown in FIGS. 4 (A), 4 (B) and 4 (D) is minimized. Since the length of the distance H of the upper line gradually changes until the length of the distance H of the upper line becomes maximum as shown in FIG. The rotation mode of the wheel 10 when the body 1 travels can be varied, and the travel mode of the traveling body 1 can be interesting.

  As shown in FIG. 5, the wheel 10 is brought into contact with the outer side surface 2 of the traveling body 1 so that the direction of the axis 4 of the traveling body 1 and the rotation direction of the wheel 10 are orthogonal to each other, and the rolling element 30 is moved to the wheel holding portion. 3 may be magnetically attached. Also in this case, the same operations and effects as described above are achieved.

  FIG. 6 shows a wheel 10 of a toy G according to the second embodiment of the present invention. The wheel 10 is different from the first embodiment in that the connecting member 24 is composed of a rod-shaped member, and is formed by arranging a plurality of rod-shaped members in an annular shape. Other configurations are the same as those in the first embodiment. Also by this, there exists an effect | action and effect similar to said 1st embodiment.

  FIG. 7 shows a wheel 10 of a toy G according to the third embodiment of the present invention. Unlike the second embodiment, the wheel 10 has an opening 32 formed only on one side of the pair of side plates 23. Other configurations are the same as those of the second embodiment. Also by this, there exists an effect | action and effect similar to the said 1st and 2nd embodiment.

When the opening edge 32a of the opening 32 is the inner peripheral surface 22 as in the first to third embodiments, the connecting member 24 may be formed in any way, and accordingly, the appearance of the wheel body 20 is increased accordingly. Can be formed interestingly.

FIG. 8 shows a wheel 10 of a toy G according to the fourth embodiment of the present invention. In the present wheel 10, unlike the first embodiment, the rolling element 30 is formed of a disc 34, the side plate 23 of the wheel body 20 is formed in a perfect circle shape, and the opening 32 is a pair of side plates 23. It is formed only on one side.
The rolling element 30 is formed of a disk 34, and a shaft body 33 projects from the center of the disk 34. This rolling element 30 is comprised with the magnet. In addition, you may comprise the rolling element 30 with the magnetic attachment body magnetically attached to a magnet.
The side plate 23 is formed in a perfect circle shape such that the value of the distance H of the upper line / the distance h of the lower line is always H / h> 3. The outer periphery of the pair of side plates 23 is an outer peripheral surface 21, and the inner surface of the connecting member 24 is an inner peripheral surface 22. That is, the shape of the outer periphery and the shape of the connecting member 24 are formed in a similar shape. When the rolling element 30 is sandwiched between the pair of side plates 23, the shaft body 33 of the rolling element 30 protrudes from the side plate 23 on the side where the opening 32 is formed and is exposed.
Further, a retaining member 27 that prevents the rolling element 30 from slipping out of the side plate 23 is provided between the rolling element 30 and the side plate 23 on the side where the opening 32 is formed. The retaining member 27 is formed in a ring shape using a plate material. Specifically, the outer diameter is larger than the minimum diameter of the opening 32, and the inner diameter is smaller than the diameter of the disk 34. The retaining member 27 does not need to be used when the diameter of the disc 34 is formed larger than the minimum diameter of the opening 32.
Other configurations are the same as those in the first embodiment.

  When traveling the toy G according to the fourth embodiment, first, the wheel 10 is placed on the outer surface 2 of the traveling body 1 so that the direction of the axis 4 of the traveling body 1 and the rotation direction of the wheel 10 are parallel. The rolling element 30 is magnetically attached to the wheel holding part 3. At this time, of the pair of side plates 23, the side plate 23 in which the opening 32 is formed is positioned on the traveling body 1 side and magnetized.

In this state, the outer peripheral surface 21 of the wheel 10 is grounded to the ground surface, and, for example, human power is applied to the traveling body 1 to push the traveling body 1 in the rotation direction of the wheel 10. When the traveling body 1 is pushed, the shaft body 33 of the rolling element 30 that is rotatably magnetized around the wheel holding portion 3 of the traveling body 1 moves along the opening edge 32 a of the opening 32. The disc 34 and the shaft body 33 move in the same direction as the traveling body 1 while rolling on the inner peripheral surface 22. Since the rolling element 30 is formed by the circular plate 34, it is easy to roll on the inner peripheral surface 22. As the rolling element 30 moves, the rolling element 30 rolls on the inner peripheral surface 22 of the wheel main body 20, and the wheel main body 20 rotates by the frictional force between the outer peripheral surface 21 of the wheel main body 20 and the ground contact surface.
This also has the same effect as the first to third embodiments.

  FIG. 9 shows a wheel 10 of a toy G according to the fifth embodiment of the present invention. In the present wheel 10, unlike the fourth embodiment, the shape of the side plate 23 is formed in a substantially elliptical shape. Other configurations are the same as those of the fourth embodiment. This also exhibits the same operations and effects as the fourth embodiment.

  FIG. 10 shows a wheel 10 of a toy G according to the sixth embodiment of the present invention. In the present wheel 10, unlike the fourth and fifth embodiments, the side plate 23 has a substantially triangular shape. Other configurations are the same as those of the fourth and fifth embodiments. This also exhibits the same operations and effects as the fourth and fifth embodiments.

  FIG. 11 shows a wheel 10 of a toy G according to the seventh embodiment of the present invention. In the present wheel 10, unlike the fourth to sixth embodiments, the shape of the side plate 23 is formed in a substantially square shape. Other configurations are the same as those of the fourth to sixth embodiments. This also exhibits the same operations and effects as the fourth to sixth embodiments.

  FIG. 12 shows a wheel 10 of a toy G according to the eighth embodiment of the present invention. In the present wheel 10, unlike the fourth to seventh embodiments, the side plate 23 has a substantially heart shape. Other configurations are the same as those of the fourth to seventh embodiments. This also exhibits the same operations and effects as the fourth to seventh embodiments.

  Thus, since it is possible to run the traveling body 1 by rotating the wheel 10 regardless of the shape of the outer periphery of the wheel 10, when a plurality of wheels 10 are magnetically attached to the traveling body 1, As shown in FIG. 13, wheels 10 having different outer peripheral shapes can be magnetically attached to the traveling body 1, and in this case, since the plurality of wheels 10 have different rotation modes, the traveling body 1 can travel further. The aspect can be interesting. In addition, since the rolling element 30 is magnetized and held on the wheel holding portion 3 of the traveling body 1, the wheel 10 can be easily attached to and detached from the traveling body 1, and therefore, a plurality of different outer peripheral shapes can be obtained. Even when the wheels 10 are magnetized, the wheels 10 can be easily replaced.

In the above embodiment, the traveling body 1 is formed as described above. However, the present invention is not necessarily limited to this. For example, as shown in FIG. The wheel holding part 3 is constituted by a magnet itself or a case body incorporating a magnet, and the wheel holding part 3 is magnetically attached to the traveling body 1 composed of a can. The wheel 10 shown by may be magnetized.
Moreover, in the said embodiment, although the magnet was accommodated in the traveling body 1, it is not necessarily limited to this, You may accommodate the magnetic attachment magnetically magnetized to a magnet, and it does not interfere and changes suitably. In this case, the rolling element 30 may be composed of a magnet.

Naoma was, in the above SL embodiment, although the shape of the outer periphery of the side plate 23 is formed in the shape described above, not necessarily limited thereto, may be formed in any shape, suitably modified There is no problem.
Further, in the above-described embodiment, the connecting member 24 is formed in a ring shape using a plate-like or rod-like member. However, the present invention is not necessarily limited to this, and any member may be used. It does not need to be formed, and can be changed as appropriate .
