Description

The present invention relates to a toy building block piece and a toy building block made by using a plurality of the toy building block pieces.

Conventionally, techniques related to a wide variety of toy building blocks have been proposed, and a wide variety of toy building blocks are actually sold. Here, in the present invention, the configuration of the smallest unit constituting the "building block" is referred to as a "building block". In addition, "building block" and "building piece" may be collectively expressed as "building block".

This "building block" is not only a building block for toys for children's mere play, but also a building block for educational toys or educational toys aimed at improving the creativity and mathematical talent of children (especially infants). Etc. are also widely known. In addition, building blocks for educational toys and building blocks for educational toys may be used as a means of rehabilitation and cognitive prevention.

For example, in Patent Document 1, for the purpose of "providing a building block that significantly increases the benefits in use and production" (see the first page of the specification, lines 15 to 16), ". It is a combination of large and small regular triangle pieces (1) (2), equilateral rhombus pieces (3), and isosceles trapezoidal pieces (4) that are similar in shape, and the small triangle piece (2) is a large triangle piece (1) on one side. The half length of is one side, the diamond-shaped piece (3) is a shape in which two small triangular pieces (2) (2) are joined together, and the trapezoidal piece (4) is a triangular piece (1) to a triangular piece (2). ) Is cut out to form a building block toy (see "2. Scope of Request for Registration of Practical New Ideas", Fig. 1, Fig. 3, Fig. 5, etc.).

Further, in Patent Document 2, "the purpose is to provide educational blocks that are not dangerous even if they are used privately by infants, are not damaged even if dropped, and can be stacked diagonally" (Specification No. 2). (Refer to pages 14 to 16 on page 2), "Educational blocks characterized by having at least elasticity and a trapezoidal cross section" (page 1 of the specification, "2. Request for registration of a practical new proposal". (2) ”, see FIG. 1).

Further, in Patent Document 3, in the technical field of "general-purpose building blocks for children" (see paragraph [0001] of the specification), "today, there are many building blocks for children. Is uniform and has a limited number of assembly surfaces to fit into, which makes it unattractive. There is little change in possible shapes, which significantly reduces the child's imagination, so the choice of angle is Only a minimal geometric structure is assembled. In addition, the uniform fittings further limit the position of the building blocks. There are fewer fittings in the middle and more precision. The required structural possibilities are limited. Last but not least, the lack of sufficient assembly surfaces to fit wastes the structural possibilities of the final assembly. In order to solve the conventional problem of "restricting" (see paragraph [0002] of the specification), "a plurality of basic geometric building blocks that can be combined with each other to assemble a three-dimensional structure". (See paragraph [0003] of the specification), "general purpose building blocks of various sizes have blocks formed by a plurality of parallel stacked blocks, each of which has a plurality of geometric shapes. A plurality of blocks that are identical and have a uniform thickness, the block having an inner surface and an outer surface, the inner surface forming a recess and the outer surface forming a convex portion. The assembly surface for fitting the unevenness is formed by alternately stacking at least four geometric shapes, and the geometric shape is formed in the longitudinal direction. The alternating stacks, which are offset by the same distance in the width direction, have every other parallel and overlapping geometric shape, and are first due to the mating assembly surface of the plurality of irregularities. A slideable bond is provided to the user from the block to the second block, which fits the concave portion of the first block with the convex portion of the second block, the first block. A general-purpose building block characterized by being formed by fitting a convex portion of a block and a concave portion of the second block "(see" Claim 1 ", FIGS. 1A to 14B, etc.) is described. ..

The "stacked toy" of the invention described in Patent Document 1 is described in Patent Document 1 as "similar large and small equilateral triangle pieces (1) (2), equilateral rhombus pieces (3), and isosceles trapezoidal pieces (4). As described in "Combination" ("2. Scope of Request for Registration of Practical New Ideas", see Fig. 5), the invention is based on the premise that a plurality of stacking pieces having similar shapes or different shapes are used. Yes, it is recognized that there is no technical idea of using stacking pieces of the same shape and size. Therefore, it is expected that the "benefits in use and manufacturing" are inferior to the technique using building blocks of the same shape and size. In addition, "the trapezoidal piece (4) has its upper and lower sides (d) (d') equal to one side (b) (c) of the small triangular piece (2) and the large triangular piece (1), respectively, and its height (h). Is formed into a trapezoidal solid with half the height of the triangular piece (1) so that one trapezoidal piece (4) can be formed by three triangular pieces (2) (2) (2). " (Refer to lines 11 to 15 on page 2 of the specification.) Regarding the front surface of the trapezoidal shape of the "trapezoidal piece (4)" (the surface seen from the direction perpendicular to the paper surface). Although the sides (d) (d') and height (h) have been specified, the left and right sides of the "trapezoidal piece (4)" (the surface seen from the left and right directions of the paper surface) and the top and bottom surfaces (viewed from the upper limit direction of the paper surface). There is no description or suggestion in the specification regarding the shape of the trapezoid.

Further, in Patent Document 2, the shape of the trapezoid in the cross section of the "educational stack 10" is "since one of the internal angles of the isotropic trapezoid is 108 °, the other internal angle is 72 °" (Specification No. 2). See pages 17 to 18 on page 3.), "The dimensions of each part are 400 mm x 295 mm for the side surface 11, 400 mm x 190 mm for the top surface 12, 400 mm x 370 mm for the bottom surface 13, 295 mm for the hypotenuse, and 370 mm for the bottom. Since it is described that the height is 280 mm (see page 3, line 18 to page 4, line 2, FIG. 1 of the specification), the invention described in Patent Document 2 is "educated." The "educational stacking tree 10" has the technical idea that the "educational stacking tree 10" is composed of regular triangles with three internal angles of 60 ° each, and the two opposing "side surfaces 11" and "top surface 12" all have the same shape. -It is recognized that there is no technical idea of forming squares of the same size, and there is no description in Cited Document 1 that suggests the technical idea.

There is a "geometric shape", and there is a description that this "geometric shape includes a trapezoid" (see "claim 6"), but there is also a description of a specific configuration for building blocks having a trapezoidal geometric shape. Not shown. Further, as described above, when a plurality of "building blocks" are stacked, they are "shifted by the same distance in the length direction and the width direction", and the "block" composed of the plurality of "building blocks" is "uneven". Is provided to form a "general-purpose building block" consisting of a plurality of "blocks" by fitting the "unevenness". It requires a difficult technique for children to accurately "shift by the same distance in the length direction and the width direction" and fix it.
