Description

本考案は、玩具や小物雑貨等に用いられる組み立てブロックに関するものである。The present invention relates to an assembly block used for toys and accessories.

従来、組み立てブロックは組立の単位となる直方体、立方体あるいは円柱や多面角柱等形状を有するものを複数個用いてこれらを適宜接合し、多様な形状の構造体を形成させる玩具としてひろく普及している。それぞれの接合には通常その材料として用いられる樹脂や木材から成るブロック表面に適宜凹凸部を設けこれらを互いに嵌め合うことを利用して接合したり、互いに添着できるカギ状突起とこれの受け穴をその表面に配設される布を設けたり磁力を用いたりしている。2. Description of the Related Art Conventionally, assembly blocks are widely spread as toys that form a structure having various shapes by appropriately joining a plurality of rectangular blocks, cubes, cylinders, and multi-faceted prisms as a unit of assembly. . Each joint is usually made by using irregularities on the block surface made of resin or wood, which are usually used as the material, and fitting them together, or by attaching key-like projections and receiving holes for them. A cloth disposed on the surface is provided or magnetic force is used.

本考案はブロックを外形の包絡形状が正方形(以下正方形)の板状のものと長辺が正方形と同じで短辺がその半分の長さの包絡形状が矩形長方形(以下矩形)の同板厚の板状の2種とし、これらの複数ブロックの接合には各ブロックの面どうしが互いに直交するよう各ブロックに設けられる共通な形状の切り欠き状ミゾ部どうしの嵌めあいを用いる2種のモジュール構成でなされる。In the present invention, the block has the same envelope thickness as a square plate (hereinafter referred to as a square) and a rectangular shape (hereinafter referred to as a rectangle) having an envelope shape whose long side is the same as a square and whose short side is half the length. Two types of modules that use notches in the notch-shaped groove portions of a common shape provided in each block so that the surfaces of each block are orthogonal to each other are used for joining these plural blocks Made in composition.

考案が解決しようとする課題Problems that the device tries to solve

従来の組み立てブロックが主に突起部(オス部)とそれに嵌め合う陥没部もしくは穴やミゾ部(メス部)の組み合わせで行うが、この方式ではブロックどうしが互いに干渉したり立体の全方向への均等な展開に形態上制約があったりして自在な組み立てができず意図する形状の造形が困難なことがあった。本考案はブロックの平面形状が正方形およびその半分の2種の形状で板厚および切り欠き状ミゾ部を共通にするだけで各ブロックどうしの嵌め合わせにより全立体方向はもちろん平面方向にも制約なく飛躍的に自在な組み合わせが展開でき多様な造形ができるようにしようとする。The conventional assembly block mainly uses a combination of a protrusion (male part) and a recessed part or hole or groove part (female part) that fits into it. In this method, the blocks interfere with each other or in all three-dimensional directions. There are cases where it is difficult to form an intended shape because there is a restriction on the form of uniform deployment and free assembly is not possible. In the present invention, the planar shape of the block is square and half of the shape, and the thickness and the notch-shaped groove are only used in common. It tries to be able to develop various combinations by dramatically expanding combinations.

課題を解決するための手段Means for solving the problem

本考案は正方形およびその半分の矩形の外形形状の樹脂、木材、紙等の板平面に適宜数設けられる共通な形状寸法の切り欠き状ミゾ部を設けた厚さが同じにモジュール化された2種のブロックどうしあるいはその同じものどうしを複数互いに直交させ、その切り欠き状ミゾ部において嵌め合わせて接合組み立てをすることを基本とする。この切り欠き状ミゾ部は幅がほぼ板の厚みと同じでブロックの各辺の中央位置から直角にブロックの中央方向に向かいその長さは正方形の一辺の中央と中心間の長さのほぼ半分に設定され、別のブロックと同切り欠き状ミゾ部どうしがゆるすぎず強すぎない程度の嵌めあいになるように設定される。また該ブロックの切り欠き状ミゾ部側各辺の側面はその中央部に対しその辺や周辺と接する板の表および裏の両面から対称に45度もしくはそれ以下のコーナーカットで形成されその2倍となる頭頂角が90度もしくはそれ以下の楔形とし正方形やその半分の矩形の中央部にこれと直交して組み合わされ原則的に各方向からのブロックが互いにぶつからないように納められる形状とされるThe present invention is a module in which the thickness is the same as that provided with notch-shaped grooves of a common shape and provided in appropriate numbers on a plate plane of resin, wood, paper, etc., with a square and half of the rectangular outer shape. Basically, a plurality of blocks of the same type or the same type of blocks are orthogonal to each other and fitted together at the notch-shaped groove portion to be joined and assembled. This notch-shaped groove is approximately the same as the thickness of the plate and is perpendicular to the central position of each side of the block, and its length is approximately half the length between the center and the center of one side of the square. It is set so that the notch-shaped groove portions of the other blocks and the other blocks are fitted so as not to be too loose and not too strong. Further, the side surface of each side of the block on the notch-shaped groove part side is formed by a corner cut of 45 degrees or less symmetrically from both the front and back surfaces of the plate in contact with the side and the periphery with respect to the central part. The top angle is 90 degrees or less, and the shape is such that the blocks from each direction do not collide with each other at the center of the square or half of the rectangle.

考案の効果Effect of device

本考案によれば前記組み立て方式の2種モジュールのブロックで複数のブロックを多数互いに直交させて制限なくきっちりと丈夫に組み立て可能となる。特に2個の正方形のブロックをその半分の大きさの矩形ブロックを用いて平面を並べて接続すると両平面に隙間なく連続感が出てつながったり、正方形ブロックによる太く大きい面や立体の表現と半分の大きさの矩形ブロックによる細く小さい面や立体の組み合わせ接続が可能となったりして非常に自在に多様な造形ができるようになり、組み立て玩具として遊びや、知育あるいはパズルに用いたり、・;小物を収納したり置いたりするインテリア性のある置物やディスプレイ、家具等に応用展開できる。また本考案のブロックは原則的に同様形状のブロックを板材のプレス加工や樹脂材のブロー成型や射出成型加工等で適宜簡易にかつ安価に成型でき量産が容易となる。なお、類似の考案に実願2012−5788「組み立てブロック」があるが本考案は前者が正方形状のブロックのみを基本とするシンプルな方式であるのに対しこれに短辺長のみ半分の矩形形状のブロックをモジュール化して付加することで飛躍的に組み立ての自由度と多様性を向上しようとするものである。According to the present invention, a plurality of blocks can be orthogonally crossed with each other in the two-type module block of the assembly method, and can be assembled firmly and firmly without limitation. In particular, if two square blocks are connected side by side using a rectangular block that is half the size of the two blocks, there is a continuous connection between the two planes without any gaps. The combination of small and small surfaces and solids made possible by the rectangular blocks of the size allows for a wide variety of shapes, and can be used as an assembly toy for play, education or puzzles, etc. Can be applied to interior decorations, displays, furniture, etc. In principle, the block of the present invention can be molded easily and inexpensively as appropriate by subjecting a block having the same shape to the pressing of a plate material, blow molding or injection molding of a resin material, and mass production is facilitated. In addition, there is an actual application 2012-5788 “Assembly block” as a similar device, but the present invention is a simple method based on only a square block, whereas the short side length is a half rectangular shape. By adding these blocks in a modular fashion, we are going to dramatically improve assembly flexibility and diversity.

以下、本考案を図1から図3の応用実施例について説明する。図1は本考案による応用の代表例として正方形ブロックの正面図およびその側面図である。図2は同じく応用の代表例として前記正方形の半分の大きさの矩形ブロックの正面図およびその側面図である。図3は前記2種モジュールよりなるブロックを複数用いた組み立て時の構成の一例を示す図である。Hereinafter, the present invention will be described with reference to application examples shown in FIGS. FIG. 1 is a front view and a side view of a square block as a representative example of an application according to the present invention. FIG. 2 is a front view and a side view of a rectangular block half the size of the square as a typical example of application. FIG. 3 is a diagram showing an example of a configuration at the time of assembly using a plurality of blocks composed of the two types of modules.

本考案をまず応用実施例として正方形ブロックで示す。その構造は図1に示すように主にブロック大(1)、それに設けられる切り欠き状のミゾ部(2)、該ブロックの外周の辺に設けられるカット部(3)から構成される。ブロック大(1)は樹脂、ゴム、木材、紙あるいはダンボール、セラミックス、粘土、金属等材料をプレスやコンプレッション加工、ブロー成型加工あるいは射出成型加工等で形成され、その形状は正面から見て正方形とする。この面上には互いに直角に4個の切り欠き状のミゾ部(2)が設けられそれぞれは正方形の周囲の4辺の各中央から同正方形の中心部に向かい幅(同図d寸法)は板の厚み(同図D寸法)にほぼ等しく、長さすなわちミゾ部の奥行き(同図L寸法)は各辺の長さ(同図A寸法)の4分の1、すなわち各辺から中心(Oで示す)に向かう長さ(Aの2分の1)の半分(2分の1)で図1のような形状に形成される。この寸法組み合わせで切り欠き状ミゾ部どうしは互いに各辺が相手ブロックの中心に到達するようになる。またカット部(3)は図1の側面図で示すようにその該ブロック大(1)の平面部の表と裏の両面に対しそれぞれ同一の角度Pで面取り状にコーナーカットされその頭頂部は各辺の頭書の外周に一致する。ここに角度Pは45度もしくはそれよりやや小さくし従って形成される楔型断面形状を有する辺の先端部頭頂角は角度Pの2倍で、直角(90度)もしくはそれより小さく形成される。同図1のX−X軸、Y−Y軸およびZ−Z軸はそれぞれ同ブロック大(1)の上下、左右、厚み方向の対象性を示す参考のため示す。The present invention is first shown as a square block as an application example. As shown in FIG. 1, the structure is mainly composed of a large block (1), a notch-shaped groove portion (2) provided on the block, and a cut portion (3) provided on the outer peripheral side of the block. The large block (1) is made of resin, rubber, wood, paper or cardboard, ceramics, clay, metal, etc. by pressing, compression, blow molding or injection molding, and the shape is square when viewed from the front. To do. On this surface, four notch-shaped grooves (2) are provided at right angles to each other, and each has a width (dimension d in the figure) from the center of each of the four sides around the square toward the center of the square. It is almost equal to the thickness of the plate (dimension D in the figure), and the length, that is, the depth of the groove (L dimension in the figure) is one-fourth of the length of each side (dimension A in the figure), that is, centered from each side ( It is formed in a shape as shown in FIG. 1 with a half (1/2) of a length (1/2 of A) toward (O). With this combination of dimensions, the cutout groove portions reach each other at the center of the opponent block. Further, as shown in the side view of FIG. 1, the cut portion (3) is corner-cut into a chamfered shape at the same angle P with respect to both the front and back surfaces of the flat portion of the block size (1). Matches the outer perimeter of each side. Here, the angle P is 45 degrees or slightly smaller, and therefore the apex angle at the tip of the side having the wedge-shaped cross section formed is twice the angle P, and is formed at a right angle (90 degrees) or smaller. The XX axis, YY axis, and ZZ axis in FIG. 1 are shown for reference showing the objectivity in the vertical, horizontal, and thickness directions of the same block size (1), respectively.

図2は本考案で前記図1に示した正方形と組み合わせて用いる半分の大きさ形状の矩形(または長方形)ブロックの応用実施例を示す。その構造は図1と原則的に同じで図2に示すように主にブロック小(4)に設けられる切り欠き状のミゾ部(2)、該ブロックの外周の辺に設けられるカット部(3)から構成される。ブロック小(4)は該ブロック大(1)と同様に樹脂、ゴム、木材、紙あるいはダンボール、セラミックス、粘土、金属等材料をプレスやコンプレッション加工、ブロー成型加工あるいは射出成型加工等で形成され、その形状は正面から見て正方形の半分の矩形で同図のように長辺はブロック大(1)と同じ長さのAで短辺はその半分(2分の1)の長さとする。その厚さはブロック大(1)と同じ寸法Dである。この面上には互いに直角に3個の切り欠き状のミゾ部(2)が設けられそれぞれは同図のX‘−X’軸上(短辺方向)に1個とY‘−Y’軸上(長辺方向)に2個である。ここに各切り欠き状のミゾ部(2)は該矩形の長辺の一方を除く周囲の3辺の各中央から同矩形の中央部に向かい、幅(同図d寸法)は板の厚み(同図D寸法)にほぼ等しく、長さすなわちミゾ部の奥行き(同図L寸法)は長辺の長さ(同図A寸法)の4分の1、すなわち各辺から中心(Oで示す)に向かう長さ(Aの2分の1)の半分(2分の1)で図2のような形状に形成される。この寸法組み合わせで切り欠き状ミゾ部どうしは互いに各辺が相手ブロックの中心または中央に到達するようになる。またカット部(3)は図2の側面図で示すようにその該ブロック小(4)の欠き状のミゾ部(2)を有する辺に接する平面部の表と裏の両面に対しそれぞれ同一の角度Pで面取り状にコーナーカットされその頭頂部は各辺の頭書の外周に一致する。ここに角度Pは45度もしくはそれよりやや小さくし従って形成される楔型断面形状を有する辺の先端部頭頂角は角度Pの2倍で、直角(90度)もしくはそれより小さく形成される。なお同図2のX‘−X’軸、Y‘−Y’軸およびZ‘−Z’軸はそれぞれ同ブロック小(4)の上下、左右、厚み方向の対象性を示す。FIG. 2 shows an application example of a half-size rectangular (or rectangular) block used in combination with the square shown in FIG. 1 in the present invention. The structure is basically the same as in FIG. 1, and as shown in FIG. 2, a notch-shaped groove portion (2) provided mainly in the small block (4), and a cut portion (3 provided on the outer peripheral side of the block) ). The small block (4) is formed by pressing, compression processing, blow molding processing, injection molding processing or the like of materials such as resin, rubber, wood, paper or cardboard, ceramics, clay, metal, etc. Its shape is a rectangle that is a half of a square when viewed from the front, and its long side is A with the same length as the block size (1) and its short side is half (1/2) the length as shown in the figure. Its thickness is the same dimension D as the block size (1). On this surface, three notched grooves (2) are provided at right angles to each other, and each has one on the X'-X 'axis (short side direction) and the Y'-Y' axis. Two in the upper direction (long side direction). Here, each notch-shaped groove (2) is directed from the center of each of the three surrounding sides excluding one of the long sides of the rectangle toward the center of the rectangle, and the width (dimension d in the figure) is the thickness of the plate ( The length, that is, the depth of the groove (L dimension in the figure) is a quarter of the length of the long side (A dimension in the figure), that is, from each side to the center (indicated by O). It is formed in a shape as shown in FIG. 2 with a half (1/2) of the length (1/2 of A) going to. With this combination of dimensions, the notch-shaped groove portions reach each other at the center or center of the mating block. Further, as shown in the side view of FIG. 2, the cut portion (3) is the same for both the front and back surfaces of the flat portion in contact with the side having the notched groove portion (2) of the small block (4). The corner is cut into a chamfer at an angle P, and the top of the head coincides with the outer periphery of the head of each side. Here, the angle P is 45 degrees or slightly smaller, and therefore the apex angle at the tip of the side having the wedge-shaped cross section formed is twice the angle P, and is formed at a right angle (90 degrees) or smaller. The X′-X ′ axis, the Y′−Y ′ axis, and the Z′−Z ′ axis in FIG. 2 indicate the objectivity in the vertical, horizontal, and thickness directions of the small block (4), respectively.

図3は本考案のブロック大(1)の平面上の4個の切り欠き状ミゾ部(2)に直交してブロック小(4)の3個のブロックを組み合わせた応用構成例を示すが、同じ種類のブロックどうしの組み合わせも当然ながら可能なため一部に1個の組み合わせ例も示す。前記各ブロックはいずれも互いに共通モジュール化された欠き状のミゾ部(2)を嵌め合い結合される。このとき同図のように平面を見せるブロック大(1)(基準ブロックとする)の中心部Oには残りの4個の各ブロックは面を直交してその側面を見せることになる。ただしブロック小(4)のX−X軸上左のものは図2におけるX‘−X’軸上の欠き状のミゾ部(2)で結合し、他のブロック小(4)2個はいずれも図2におけるY‘−Y’軸上の欠き状のミゾ部(2)で結合した状態を例示する。これにより前者の矩形ブロック小(4)1個ではその短辺方向の欠き状のミゾ部(2)で基準ブロックと結合し残りの長辺方向の欠き状のミゾ部(2)が基準ブロックと直行方向の他のブロックへの結合可能となり、また後者の矩形ブロック小(4)2個ではその長辺方向の欠き状のミゾ部(2)を用いて同図右側X−X軸上に示す別の1個のブロック大(1)を並べて隙間なく結合させたり同図下側Y−Y軸上に示すように本図平面と直角の平面にブロック大(1)あるいはブロック小(4)をその短辺の欠き状のミゾ部(2)で結合させたりできる。Y−Y軸上に示すように基準ブロックと同じブロック大(1)を欠き状のミゾ部(2)で直行させて結合も可能である。このときの結合において基準ブロックに直交する各ブロックの基準ブロック中心Oにおける辺はいずれも衝突干渉なく組み合わせ可能となる。このため更に多くのブロックを上記の組み合わせに加えて組み合わせ結合できその例を同図3内に破線で示す。当然ながらその方向は紙面に直角な方向も自在に可能で全立体方向へ均等で多様な展開ができる。また隣り合うブロックの同一平面どうしは辺どうしが密着し隙間なく構成できる。FIG. 3 shows an application configuration example in which three blocks of a small block (4) are combined orthogonally to four notch grooves (2) on the plane of the block large (1) of the present invention. Since combinations of the same type of blocks are naturally possible, some combinations are also shown. Each of the blocks is fitted and connected with a notched groove (2) formed into a common module. At this time, as shown in the figure, at the central portion O of the large block (1) (referred to as a reference block) showing the plane, the remaining four blocks are perpendicular to each other and show their side surfaces. However, the small block (4) on the left on the XX axis is connected by the notched groove (2) on the X′-X ′ axis in FIG. FIG. 2 also illustrates a state in which they are coupled at a notched groove (2) on the Y′-Y ′ axis in FIG. As a result, the former small rectangular block (4) is connected to the reference block at the notched groove (2) in the short side direction, and the remaining notched groove (2) in the long side direction is defined as the reference block. It can be connected to other blocks in the orthogonal direction, and the latter two small rectangular blocks (4) are shown on the XX axis on the right side of the figure using a notched groove (2) in the long side direction. Arrange another large block (1) side by side without gaps, or place the large block (1) or small block (4) in a plane perpendicular to the plane of this figure as shown on the lower Y-Y axis in the figure. It can be combined at the notched groove (2) of the short side. As shown on the Y-Y axis, the same block size (1) as that of the reference block can be made to go straight through the notched groove (2) to be combined. In this connection, all the sides at the reference block center O of each block orthogonal to the reference block can be combined without collision interference. Therefore, more blocks can be combined and combined in addition to the above combinations, and an example thereof is shown by a broken line in FIG. Of course, the direction can also be a direction perpendicular to the paper surface, and can be developed in a uniform and diverse manner in all three-dimensional directions. In addition, the same planes of adjacent blocks can be configured with no gaps between the sides.

前述の各ブロックの組み合わせ以外に同じ形状どうしの組み合わせは多様に可能で逐次図示しないがいずれも共通モジュ−ル化された欠き状のミゾ部(2)を介して展開可能となる。なお、欠き状のミゾ部(2)の個数を本例より増減したり各ブロック形状のコーナー部や切り欠き状ミゾ部の角を丸めたり多少の大きさを変化させたりブロック表面の色や模様等を変化させたり補助的なブロックを追加したりしても本考案の主旨と相違しない限り本考案に包含される。Various combinations of the same shapes other than the combinations of the blocks described above are possible, and although not sequentially illustrated, any of them can be developed via the notched groove portion (2) formed into a common module. The number of notched grooves (2) can be increased or decreased from this example, the corners of each block shape and the corners of notched grooves can be rounded, the size can be changed slightly, and the color and pattern of the block surface. It is included in the present invention as long as it does not differ from the gist of the present invention even if the above is changed or an auxiliary block is added.
