first embodiment

[0033] A. First Embodiment

[0034] First, as shown in FIG. 1, the shoe last manufacturing system of the present embodiment comprises foot measurement unit 10, personal computer system (shoe last design unit) 11, and NC (Numerically Controlled) machine tool 12.

[0035] Foot measurement unit 10 is a unit for producing size data showing a foot size of a user by measuring the configuration of a foot of the user. Foot measurement unit 10 uses a non-contacting type three dimensional configuration measurement unit in the present embodiment as shown in FIG. 2. As shown in FIG. 2, foot measurement unit 10 comprises tightening unit 22, foot configuration measurement unit 24, and displaying unit 26. Tightening unit 22 prevents movement of the user's foot during measurement, and comprises, as shown in the figure, rolling unit 22a to be rolled around a calf of the user, and supporting unit 22b for supporting and fixing rolling unit 22a. As shown in the figure, rolling unit 22a is rolled around the c...

modification 6

[0081] (Modification 6)

[0082] When a shoe last configuration data production process is carried out, in which the design of the ordered shoe (for example, a design where the tip of the shoe is square), or configuration data of the shoe last (for example, taking the height of the heel and so forth into account) can automatically be produced, shoe last data can be produced by preparing a conversion table for classification of a plurality of designs of shoes or the height of each heel (for example, 0 to 1 cm, 1 cm to 2 cm), choosing a conversion table in accordance with the designated design or height of the heel, and referring to the chosen conversion table.

modification 7

[0083] (Modification 7)

[0084] In the above-mentioned modification, when configuration data of a shoe last taking into account information such as the design of the shoe, the height of the heel, the type of the foot (such as Egyptian foot, Greek foot, hallux valgus, or pes latus), fleshiness of the user's foot (for example, subcutaneous fat percentage) is produced, a plurality of conversion tables are prepared, and when the foot type is Greek foot, the conversion table corresponding to Greek foot is chosen and referred to. By preparing several conversion tables in this manner, configuration data of shoe lasts taking into account the several types of information mentioned above can be produced, but on the basis of configuration data of the shoe last produced by shoe last configuration data production unit 32 of the first embodiment mentioned above, the basic configuration data can be amended by taking into account information such as the design of the shoe, the height of the heel, the...

Abstract

Measured size data of a foot of a user is inputted into foot size data inputting unit 31, and provided to shoe last configuration data production unit 32. Also, in conversion table 33, is stored conversion data produced on the basis of the relationship between a foot size and a size of a shoe last for producing a shoe which fits in the foot determined by an experiment. Shoe last configuration data production unit 32, by referring to conversion table 33, produces ideal size data of a shoe last on the basis of inputted size data of a foot.

Description

[0001] The present invention relates to a shoe last design method for designing a shoe last used for shoe manufacturing, a shoe last design unit, a preferable foot measurement unit for designing a shoe last, and a foot spot determination unit of a foot measuring unit.[0002] A shoe last is used to make a pattern paper for producing each part of a shoe. A shoe last is also a workbench for installing an inner sole and an outsole when a shoe is assembled. A shoe last further functions as an ironing board for determining a style of a shoe by maintaining its assembled shape until the glue used in the assembly process, along with any other moisture, evaporates after the shoe is assembled. Thus, a shoe last functions in various manners when a shoe is manufactured. Further, the configuration of a shoe last determines the configuration of the completed shoe.[0003] Shoe lasts fall into two categories: mass production shoe lasts used for mass production of shoes; and a custom order shoe last us...
