Abstract

<P>PROBLEM TO BE SOLVED: To provide an expansion assembly type human body-shaped model form CAD for generating an expansion assembly type expansion diagram according to an individual body by solving the problem that an individual human body shape dealing form depends on gypsum pouring and cutting, and that the cutting time, storage place and discard place are turned into nuisances. <P>SOLUTION: At first, a basic model constituted of curved surfaces which are turned to be flat surfaces when expanded or flat surfaces is prepared, and the respective faces are defined as the gathering flat surfaces of triangular polygons, and made flat, and combined so that an expansion assembly type expanded diagram can be created. When the basic model-shaped polygon which is the same as an assembly finish status is deformed according to the body shape of an individual person, the expanded diagram is changed following this. Thus, it is possible to instantaneously obtain an expansion assembly type human body shape model form expanded diagram corresponding to the body shape. <P>COPYRIGHT: (C)2004,JPO

Description

【0001】
【発明が属する技術分野】
本発明は、個人の人体形状、姿勢に合わせた製品の立体のモデル型を展開組み立て式の展開図を出力するCADに関する。
【0002】
【従来の技術】
従来、人体形状は複雑な曲面が多く、石膏で型を取ってさらに石膏を型の中に流し込んでいた。特に靴型は木型や、プラスティク、金属であり、フルオーダーで作るには切削によっていた。立体の切削時間は非常に時間、コストがかかり、光造形、積層して造形する方法もあったが、保管場所を必要とし、排出する、切削ゴミ、いらなくなった本体の廃棄が大変だった
【0003】
【発明が解決しようとする課題】
解決しようとする問題は、複雑な曲面に覆われた人体形状に基づく製品立体のモデル型を、単純な曲面、平面で構成したモデル型で、板材加工の出来る展開組み立て式モデル型に置き換え、体形、対象となる製品としての必要なパラメータを入力すると瞬時にその展開図を出力するし、体形にあった展開組み立て式人体形状モデル型を作れるようにすることである。
【0004】
【課題を解決するための手段】
本発明は、始めに、体形の特徴点(1)と製品の特徴点(2)をゆとりや材質の伸びを取り入れて関連付け、特徴点と特徴点を結ぶ制御可能な曲線で形状を制御出来る立体の基本モデル型(図5)を用意する。モデル型の面は、面と面の曲線上の分割点を共有し、特徴点同士、特徴点と曲線の分割点(6)、向かい合う特徴点を結ぶの分割点を交互に結び合ってできるポリゴン(7)で構成する。それにより面が展開されても隙間なく、立体に組み立つ。三角形ポリゴンは頂点の座標値から、辺の長さ、其々の角度を求め、2次元の三角形としての座標値を持つことが出来る。同じ集合の隣り合う三次元ポリゴンで互いに共有しあう頂点同士を平面上で順次に共有する頂点へ座標移動、連結し、ポリゴングループ展開面を生成出来る(図3)。その平面展開面ブロックを全体展開図として、重なり合たり不具合がないように組み立て、選択された共有する頂点を結合し合いながら、ブロックごとに座標移動し、基本となる展開図を作る。実際の型を紙などで板加工して使用可能にするための糊代、差込を設け、展開組み立て式人体形状モデル型展開図(図5)とする。出来上がりの状態と同じ基本モデル形状のポリゴンを個々人の体に合わせて変形すると、同時に展開図も追従して変化するので、個人の体に合わせた展開組み立て式人体形状モデル型が瞬時に得られる。
【0005】
【発明の実施の形態】
人体形状に関するモデル型であれば、ドレスマネキン、骨折部の固定型、装具の型、手袋、帽子など、様々な型を、展開組み立て式人体形状モデル型に出来るが、最も板紙では出来ないとされていた靴型に関して実施してみた。靴の展開可能な曲面(3)や平面で構成した立体基本モデル(図6)を用意し、曲面ごと、三角形ポリゴン同士、グループ化(図4)し、其々の平面展開ブロックを組み立てやすく靴型底部(7)、靴型上部(8)に分けて結合し、靴型を組み立てるのに必要な折り線(14)、糊代(9)、差込ベロ(10)、差し込み穴(11)などを付け、さらに中底取り付け穴(12)など靴型としての必要な機能を付加し、展開組み立て靴型展開図とする。
【0006】
【実施例】
図6は基本モデルの靴型で展開組み立て式靴型が組み立ったときの形であり、図5はその形体に合わせて展開された展開組み立て式靴型の展開図である。
【0007】
【発明の効果】
展開図に対する知識を必要とせず、製品の種類を選択し、足の測定結果や、ヒールの高さなど入力すれば、フルオーダーメードの靴であっても一人一人の足に合わせて、靴型の展開図を瞬時に得ることが出来るので、板紙などの板材を切り組み立て、底付けの時、必要であれば、中に詰め物を充填すれば、安価に靴型を作る事が出来るようになった。元々、展開による靴型なので、それに基づき甲革の展開図面を引き出すのに容易であり、直接その上にデザインを書き、切りぬいて靴の甲革のデザインになるのでモックアップにも使える。保管にも場所をとらず、紙であれば。廃棄も簡単である。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a CAD that outputs a three-dimensional model of a product according to the shape and posture of an individual by developing and assembling a developed model.
[0002]
[Prior art]
Conventionally, a human body shape has many complicated curved surfaces, and a plaster was cast and plaster was further poured into the plaster. In particular, lasts are wooden, plastic, and metal. The three-dimensional cutting time is very time-consuming and costly, and there were methods of stereolithography and lamination, but it required a storage place, and it was difficult to dispose of the waste, cutting dust, and unnecessary bodies. 0003
[Problems to be solved by the invention]
The problem to be solved is to replace the model type of the product solid based on the human body shape covered by a complex curved surface with a simple curved surface and a plane model type, and to expand and assemble model type that can process plate materials, When the necessary parameters of the target product are input, the developed view is output instantaneously, and the developed and assembled human body model model suitable for the body shape can be created.
[0004]
[Means for Solving the Problems]
According to the present invention, first, a feature point (1) of a body shape and a feature point (2) of a product are associated with each other by taking into account room and elongation of material, and the shape can be controlled by a controllable curve connecting the feature points. The basic model type (FIG. 5) is prepared. A model-type surface is a polygon that shares the division points on the surface and the curve on the surface and alternately connects the feature points, the division points between the feature points and the curve (6), and the division points that connect the opposite feature points. (7). As a result, even if the surface is developed, there is no gap and it is assembled in a three-dimensional manner. Triangular polygons can determine the length of each side and their respective angles from the coordinate values of vertices and have coordinate values as two-dimensional triangles. Vertices that are shared by adjacent three-dimensional polygons of the same set can be sequentially moved and connected to vertices that are shared in common on a plane to generate a polygon group development surface (FIG. 3). The plane development plane block is assembled as an entire development view so as not to overlap or have a defect, and coordinates are moved for each block while connecting selected common vertices to create a basic development view. Glue margins and insertions are provided to enable the actual mold to be processed with paper or the like to make it usable, and the developed and assembled human body model model is developed (FIG. 5). When a polygon having the same basic model shape as that of the completed state is deformed according to the individual's body, the developed view changes at the same time, so that a developed and assembled human body shape model type adapted to the individual's body can be obtained instantaneously.
[0005]
BEST MODE FOR CARRYING OUT THE INVENTION
If it is a model type related to human body shape, various types such as dress mannequin, fixed type of fractured part, orthosis type, gloves, hat etc. can be developed and assembled human type model type, but it is said that it can not be done most with paperboard I tried to do it for the last I had. Prepare a three-dimensional basic model (Fig. 6) consisting of curved surfaces (3) and planes that can be developed for shoes, group triangular polygons for each curved surface (Fig. 4), and easily assemble each planar development block. The bottom part (7) and the upper part (8) are connected separately, and the fold line (14), glue allowance (9), insertion velvet (10), and insertion hole (11) required for assembling the last. In addition, necessary functions as a last, such as an insole mounting hole (12), are added to make a developed and assembled last figure.
[0006]
【Example】
FIG. 6 is a view of a basic model last when a deployable assembled last is assembled, and FIG. 5 is a developed view of the deployable last that is developed according to the shape.
[0007]
【The invention's effect】
You do not need to know the development plan, you can select the type of product, enter the measurement result of the foot, the height of the heel, etc., even if it is a fully tailor-made shoe, You can instantly obtain a development drawing of the material, so you can cut and assemble board materials such as paperboard and fill it with fillings if necessary at the time of bottoming, making it possible to make shoe lasts at low cost Was. Originally, it is an unfolded last, so it is easy to draw out a development plan of the upper based on it, and the design can be directly written on it and cut out to become the upper design of the shoe, so it can be used for mock-up. If it is paper, it does not take up space for storage. Disposal is easy.
