DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of assembling various flat and three-dimensional bodies using a rod member and a connecting member, and comparing the sizes of internal spaces of various assembled bodies. The present invention relates to an assembling educational toy for an infant or a younger child who can learn by learning.

[0002]

2. Description of the Related Art There have been many inventions for assembling educational toys capable of assembling various planar shapes and three-dimensional shapes by connecting ends of a plurality of rod members using a connector. Various ideas have been proposed.

[0003] As an example thereof, one disclosed in Japanese Utility Model Laid-Open No. 2-58498 is composed of a connecting pipe and an elastic connecting device having a plurality of connecting limbs of the same thickness. The adjacent angle of the adjacent limb in the plane is set to be larger (to 120 degrees) than the angle at the time of use, and the limb is bent from its base in a desired direction at the time of use to adjust to the required angle. Are ready to use.

In this assembling educational toy, if a plurality of connecting pipes and a plurality of connecting tools having a necessary number of connecting limbs to connect the ends of the connecting pipes at each corner are prepared, Various planar and three-dimensional objects that can be used as educational toys can be assembled.

For example, in order to assemble the most basic square shape, four connecting pipes of a predetermined length and four connecting tools having two connecting limbs are prepared, and two connecting limbs of each connecting tool are connected. If it is bent at 90 degrees and inserted into the end of the connecting pipe and connected, a square shaped body can be assembled.

[0006]

However, in the assembling educational toy having the above structure, the connecting tool is made of an elastic material, and the adjacent angle of the adjacent connecting limb is set to an angle larger than an angle required at the time of use. When the angle is adjusted by bending the connecting limb at the time of use, the connecting limb tends to expand due to elasticity.Bend the connecting limb to the required angle first, and leave the end of the connecting pipe as it is. It cannot be inserted into a part and connected.

Therefore, in actual assembly work, first,
Inserting the connecting limb into one end of the connecting pipe, bending the connecting limb with the connecting pipe in hand, maintaining this state, and connecting the other connecting pipe end is necessary. The workability is poor. In addition, such assembling work requires a certain amount of dexterity,
Work procedures are required, so even if a simple planar body is assembled, for infants and younger children,
It is difficult to assemble by yourself.

Further, as described above, in the connecting device made of an elastic material, even after assembling the desired shape, the connecting limb bent at the time of assembling shows a tendency to elongate. There is a case where the shaped body naturally falls out of the end of the pipe, and there is a concern about the stability of the shaped body after assembly.

Furthermore, in the assembled educational toy having the above-mentioned configuration, one connecting tool is used at each corner, and the connecting tool has the same number of connecting limbs as the number of connecting pipes connected at the corner. Since it is necessary, many types of connecting tools with different numbers of connecting limbs must be prepared for each, according to the number of connecting pipes connected at the corner,
The number of types of parts increases and the handling becomes complicated.

Therefore, the present invention has been made to solve the above-mentioned problem, and anybody can easily and surely assemble from a planar shape to a three-dimensional shape by reducing the types of parts. The purpose of the assembled body is to provide an assembling educational toy having excellent stability.

[0011]

In order to achieve the above object, an assembled educational toy according to the present invention comprises a pair of rods having connecting holes at both ends rotatably connected around a connecting core. A member and a connecting member having two connecting limbs that can be fitted into the connecting holes of the rod-shaped body, the center of rotation of the rod-shaped body is set on the axis of the connecting core, and the two connecting limbs of the connecting member are The adjacent angle is set to a predetermined fixed angle.

Here, although there is no restriction on the material of the rod member and the connecting member, they are generally formed from a synthetic resin material. The pair of rods are connected to the connecting core so as to be in contact with each other, and can freely rotate around the connecting core. As a general-purpose braided member, with one bar fixed
It is preferable that the other rod-shaped body can be rotated around the connecting core in a range exceeding 180 degrees. In addition, the connecting limb of the connecting member is inserted into the connecting hole at both ends of the rod-shaped body at an appropriate depth, and a frictional force is exerted to prevent the limb from being pulled out. In the direction of insertion.

[0013] According to the assembled educational toy according to the present invention thus constructed, the number of rod members required according to the planar shape or the three-dimensional shape to be assembled, and each rod-shaped member of these rod members are required. Prepare the necessary number of connecting members for connecting. At this time, the connecting member selects an adjacent angle between two adjacent connecting limbs according to the planar shape or the three-dimensional shape to be assembled.

Anybody can easily assemble the target shaped body simply by inserting the connecting limbs of the connecting member into the connecting holes so as to abut the ends of the rods and connecting them.
Here, since the connecting limb is easily and firmly inserted into the connecting hole, the connecting limb does not naturally fall out of the connecting hole after assembling, and the assembled shape does not collapse for a long time. Stabilize.

[0015] In the assembled educational toy according to the present invention, the rod-shaped body has a configuration in which both side surfaces are aligned with a virtual extension surface extending in two directions at a predetermined angle from the axis of the connecting core body, and the connecting member comprises: On the rod-shaped body, both sides are matched to the side of the rod-shaped body, extended to the center line of the connecting core and joined in a V-shaped cross section to form a ridge line, and a ridge line extending in two directions to form a cornered outer edge Then, the connection member used for the connection of the fixed-size rod-shaped body adopts a configuration in which the lengths of the ridge lines of all the connection members are set to the fixed size, regardless of the adjacent angles of the two connection limbs.
In the assembled rod member, the connection relationship between the coupling core and the pair of rods is such that a part of the rod having an isosceles triangular cross section is protruded from the coupling core, and the rods are connected by the coupling member. The connecting relationship between the rod-shaped body and the connecting member takes a form in which connecting members having an isosceles triangular cross section are connected on the rod-shaped body. In this way, the connection angle of the rods connected by the connection member is clearly represented by the angled outer edge of the connection member, and this connection angle can be easily recognized. Also, in terms of appearance, the assembled body is in the form of a rod-like body having an isosceles triangular cross section, and is finished in an eye-catching shape. In addition, by setting the length of the ridge line of all the connecting members to a fixed size, not only a specific shape but also a complex shape using a fixed size braided member can be assembled, and each corner can be assembled. In the part, the outer edge corners of the connecting member are aligned and finished neatly.

Further, a face plate may be formed in accordance with a planar space surrounded by the connected rod-shaped members, and face plate coupling means may be provided on the edge of the face plate and the outer surface of the corresponding rod-shaped member. The face plate connecting means can be constituted by a concave / convex fitting portion provided on the side surface of the face plate and the outer surface of the rod-shaped body. For example, when a projection is provided on the edge of the face plate, a concave portion is provided on the outer surface of the rod-shaped body corresponding to this, and at the stage of assembling the target shape body, the projection on the face plate edge is fitted into the recess on the outer surface of the rod-shaped body to assemble the shape body. In the assembled shape, a face plate is stretched in a space surrounded by the connected rods, so that the form of each surface of the assembled shape is clearly expressed, and the understanding and utilization of the shape are improved. be able to. Further, the assembled body has improved pressure resistance against external pressure, and also has excellent form stability. Further, when the face plate is used, it is possible to assemble using only the assembled rod member and the face plate without using the connecting member, and further, the assembly is simplified.

Embodiments of the present invention will be specifically described below with reference to the drawings.

FIG. 1 is a front view showing a cross section of a part of an assembled educational toy showing an embodiment of the present invention.

In FIG. 1, A represents an assembled educational toy, that is, a planar shape body in this case, and the shape body is assembled by a rod member 1 and a connecting member 2. Both members 1,
2 is not particularly limited in material, but in the embodiment,
It is composed of a molded product made of synthetic resin material.

As shown in FIGS. 2 and 3, a pair of rod members 4 having connecting holes 3 at both ends thereof are connected to a connecting core 5 so as to be rotatable around the connecting core 5, as shown in FIGS. In the embodiment, the connecting core 5 is formed into a columnar shape, which is divided into three pieces at both ends 5a and a middle piece 5b.
The supporting shaft 6 provided at the center of both end faces of the
a, and is inseparably joined by being fitted into a bearing concave portion 7 provided on the inner end surface of the inner end surface 5a, one rod-shaped body 4 is fixed to the side surface of both end pieces 5a, and the other rod-shaped body is The two rod-shaped members 4 are rotatable around the connecting core 5 around the axis of the connecting core 5.

Further, in the embodiment, both sides of the rod 4 are aligned with virtual extension surfaces extending in two directions at a predetermined angle from the axis of the connecting core, that is, from the connecting core 5. The rod-shaped body having an isosceles triangular cross section is partially protruded. Further, the angle at which the rod 4 rotates around the connecting core 5 is set in consideration of versatility, but in the embodiment, one rod 4 is fixed while the other rod 4 is fixed. The connection core 5 is rotatable in a range exceeding 180 degrees.

As shown in FIGS. 4 and 5, the connecting member 2 has two connecting limbs 8 which can be fitted into the connecting holes 3 of the rod-shaped body 4.
The adjacent angle of the two connecting limbs 8 is set to a predetermined fixed angle. That is, the adjacent angle of the two connecting limbs 8 of the connecting member 2 is set according to the shape to be assembled. The connecting member 2 shown in FIGS. 4 and 5 sets the adjacent angle of the two connecting limbs 8 to 90 degrees, and is for connecting the rod-shaped body 4 at a right angle.

In the connection relationship between the rod member 4 and the rod member 4, the connecting member 2 is formed so that both side surfaces of the connection member 2 match the side surfaces of the rod member 4 so that the rod member 4 has continuity. At the same time, both side surfaces of the connecting member 2 are extended to the center line of the connecting core body 5 and joined in a V-shaped cross section to form a ridge line 9,
A ridge 9 extending in two directions forms a cornered outer edge, and an end surface of the connecting member 2 forms an isosceles triangle.

The two connecting limbs 8 of the connecting member 2 are inserted into the connecting hole 3 of the rod 4 to an appropriate depth.
The slippage is prevented by exerting a frictional force, and the cross-sectional forms of the two are set so that they are inserted in a predetermined direction without rotation. In the embodiment, the cross section is trapezoidal.

In the embodiment, since the two connecting limbs 8 of the connecting member 2 are used for connecting the fixed-size rod-shaped members 4, the lengths a of the ridge lines 9 of all the connecting members 2 are set to two. The fixed size is set regardless of the adjacent angle of the two connecting limbs 8. The length a of the ridge line 9 is set as follows. That is, when a fixed-size braided member 1 is used, the planar shape having the smallest number of sides assembled using the fixed-size braided member 1 is a regular triangular shape. As shown, the connecting member 2 used for assembling the equilateral triangular shaped body has a minimum ridge line length a that prevents the ends of the two assembled rod members from interfering with each other.
In accordance with this, all the connecting members 2 for assembling other shaped bodies, including the connecting member 2 used for assembling the regular hexagonal shaped body shown in FIG. Made.

Generally speaking, one connecting member 2
It is necessary to determine the length of the ridge line 9 within a range that satisfies the condition that the ends of the two assembled rod members connected by the ridge line do not interfere with each other. Since the minimum length of the ridge line 9 becomes long, in order to make the length of the ridge line 9 constant, of the connecting members 2 used,
The length a of the ridge line 9 is determined within a range that satisfies the above condition with respect to the one where the adjacent angle of the two connecting limbs 8 is the smallest, and the length of the ridge line 9 of the other connecting members 2 is also adjusted to that. Since the length of the ridge line 9 is constant, the greater the angle between the two connecting limbs 8 is, the longer the isosceles triangular prism portion of the connecting member 2 is.

Further, assuming that the length of the rod member 1 is b, the length 2 × a + b, which is the sum of the ridgelines 9 of the connecting members 2 connected to both ends of the rod member 1, is the length c of the side of the shape. I do. Even if only one kind of length is used for the braided member 1, a sufficiently versatile shape can be formed. Therefore, the length of the braided member 1 is basically a fixed size. If the bar assembly 1 is used,
Furthermore, various and desired shapes can be assembled. When two or more kinds of lengths of the rod member 1 are used, the length of the rod member 1 is set as follows. First, the length of the most frequently used braided bar member 1 is determined, and the ratio of the sides having different lengths of the shaped body is determined. Next, the length of the side that uses the rod member 1 used most frequently is calculated, and then the length of the other side of the shape body is calculated from the ratio of the side of the shape body having the length of the side just obtained, Further, the length of the bar assembly 1 is calculated back from the length of the side, and set to that length.

Further, in the assembled educational toy according to the present invention, when assembling the desired shape, the face plate 10 is stretched as necessary in the space surrounded by the connected rods 4. For this purpose, in the embodiment, the protrusion 11 is provided on the edge of the face plate made in accordance with the space, and the concave portion 12 is formed on the outer surface of the rod-shaped body 4 correspondingly. The extension of the face plate 10 to the space is performed at the stage of assembling the shaped body.

Here, the connecting member 2
Is prepared by selecting an adjacent angle of the two connecting limbs 8 according to the shape.

As shown in FIG. 1, an independent planar body A
When assembling, the rod member 4 of the rod member 1 is connected by using one of the rod members 4 and inserting the connecting limb 8 of the connecting member 2 into the connecting hole 3 so that the ends of the rod members abut each other. And assemble. As shown in FIG. 8, when assembling a planar connection shape body B in which a plurality of planar shape objects are connected in a developed shape (six regular triangles are connected in a hexagonal shape), depending on the location of the shape body B. The rods 4 of the rod assembly 1 selectively use both the rods 4 and one of the rods 4, and connect the connecting limbs 8 of the connecting member 2 to the connection holes 3 so that the ends of the rods abut each other. Insert and assemble. When assembling a three-dimensional body, the rod 4 of the rod assembly 1 uses both of the rods 4, and the connecting limb of the connecting member 2 is inserted into the connecting hole 3 so that the ends of the rods abut each other. Insert and connect 8 to assemble. When the face plate 10 is stretched in a space surrounded by the connected rods 4 in assembling the target shape, as shown in FIG. 1, the concave portion 12 on the outer surface of the rod is required at the stage of assembling the shape. Then, the shape body is assembled by fitting the projection 11 on the edge of the face plate.
