JPH0675521B2 - Pattern making method for sizing coating materials of complex three-dimensional objects such as foot-shaped - Google Patents

Description

Description: TECHNICAL FIELD The present invention relates to a method for producing a paper pattern for measuring a covering material of an object having a complicated three-dimensional shape such as a foot pattern, and more particularly,
The present invention relates to a suitable means for reasonably and economically manufacturing "easy-to-wear shoes" that conforms to the foot shape of each individual.

[Conventional technology]

In the production of various industrial products, high-mix low-volume production is the current trend, and shoes of various uses and designs are sold in the shoe manufacturing industry. However, it still does not fully respond to the needs of "easy-to-wear shoes" in a so-called ergonomic sense that matches the shape of each individual foot.

In recent years, the fact that there are potentially deep-rooted concerns and dissatisfaction with ready-made shoes for people whose foot shapes are different from the standard has finally been taken up by the media and the like.

At present, shoes are produced based on wooden patterns, but at that time, after the pattern making for the leather trimming, the actual leather trimming and sewing work is performed. The pattern making for sizing of this leather requires a great deal of labor and time by a skilled person.

[Problems to be solved by the invention]

Therefore, this inevitably resulted in high cost in shoe manufacturing.

The present invention has been made in view of the above problems of the conventional technique, and an object of the present invention is to solve the problem of sizing a coating material for an object having a complicated three-dimensional shape such as a shoe tree, even for an amateur. It is designed to enable faster and more accurate sizing work than the conventional expert, and in particular, simplifies the pattern making process for sizing, which is one of the reasons for the high cost in order-made shoe manufacturing. By doing so, it is possible to realize the pattern making for accurate and quick sizing without requiring an expert in the pattern making process.

[Means for solving problems]

For this purpose, the present invention is to heat and soften a shape memory resin thin plate and bring it into close contact with the surface of a complex three-dimensional object such as a foot-shaped mold, followed by cooling and hardening the shape memory resin thin plate, and then Drawing for shape determination on shape memory resin thin plate,
After drawing a line such as a style line, the shape memory resin thin plate is removed from the complex three-dimensional object such as the foot-shaped mold, and the hardened shape memory resin thin plate is reheated to memorize the shape memory resin thin plate itself. It is characterized in that the original flat plate shape is restored to form a pattern, and the coating material is cut based on the line drawn on the flat plate shape memory resin thin plate.

〔Example〕

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

The present embodiment is a case where a three-dimensional object is used as a foot mold and a paper pattern is made for sizing a covering material (leather) of the foot object.

More specifically, the present invention is characterized in that a shape memory resin thin plate (hereinafter, simply referred to as a thin plate) is used as a template. The shape memory resin thin plate (hereinafter simply referred to as a thin plate) is a resin having a very large molecular weight, and is a trade name Memory Rubber (registered trademark) manufactured by Maruka Co., Ltd.
Say First, the thin plates 10 and 11 having appropriate sizes are placed at 40 ° C.
Put in the above hot water to soften the softened thin plates 10, 11
Is closely attached to the surface of the foot mold (three-dimensional object) 12. After that, the foot mold 12 to which the thin plates 10 and 11 are closely adhered is soaked in water.
By cooling and hardening 10 and 11, the surface of the foot mold 12 can be impressed, and the thin plates 10 and 11 are then drawn with drawing lines and style lines 13, 14 and 15 (Fig. 1, A and B). And FIG. 2).

After that, the cured thin plates 10 and 11 are removed from the foot mold 12, and the thin plates 10 and 11 are placed in hot water of 40 ° C. or higher, the thin plate 10 and
11 It returns to the original flat plate shape that it remembered (see Fig. 3).

Therefore, the thin plates 10 and 11 that have returned to the flat plate shape are used as pattern paper,
Style lines 13 and 14 drawn on the thin plates 10 and 11,
Cut based on 15.

Note that FIG. 3 shows one thin plate 10 and the other thin plate 11 is omitted.

〔The invention's effect〕

Therefore, according to the present invention, since the shape memory resin thin plate is used as a template for sizing the covering material of an object having a complicated three-dimensional shape such as a foot-shaped pattern, even an amateur is more than a conventional expert. Speed and accurate sizing work can be realized. In particular, the pattern making process for sizing in order-made shoe manufacturing is simplified, and "easy-to-wear shoes" that match the foot shape of each individual
Can be manufactured in a short time and at low cost.

[Brief description of drawings]

1A and 1B are plan views of a shape-memory resin thin plate, and FIG. 2 is a diagram showing a pattern paper making process for sizing a foot-shaped covering material according to an embodiment of the present invention. FIG. 3 is an explanatory view showing a state where a shape memory resin thin plate is brought into close contact with the surface of the foot mold, and FIG. 10, 11… Shape memory resin thin plate 12… Foot mold 13, 14, 15… Style line

Claims (1)

[Claims] 1. A shape memory resin thin plate is heated and softened so that the thin shape memory resin thin plate is brought into close contact with the surface of a complex three-dimensional object such as a foot mold, the shape memory resin thin plate is cooled and hardened, and then the shape memory resin thin plate. The drawing, style line, etc. are drawn to determine the trimming, and then the shape memory resin thin plate is removed from the complex three-dimensional object such as the foot-shaped mold and the cured shape memory resin thin plate is heated again. Then, the pattern-making method for sizing the covering material of a complex three-dimensional object such as a foot-shaped mold characterized by returning the original flat plate shape memorized by the shape-memory resin thin plate itself to use as a template .
