  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  <Example 1> The insole design system 50 of Example 1 and the combination method of shoes and an insole are demonstrated, referring FIGS.

  FIG. 1 is a block diagram of an insole design system 50. As shown in FIG. 1, the insole design system 50 includes a controller 60, a display device 52 such as a display, an input device 54 such as a keyboard and a pen tablet, an output device 56 such as a printer, a communication device 58, A storage device 62 is connected.

  The storage device 62 includes a shoe database 70 and a foot database 72.

  The shoe database 70 is a database that stores a shoe model number and shoe data that is data of a three-dimensional shape of the shoe interior space in association with each other. The shoe database 70 may store data of not only pre-made shoes but also select order shoes for selecting a wooden pattern and full-order shoes for individually manufacturing a wooden pattern. Further, the volume of the internal space of the shoe 20 may be included in the shoe database 70.

FIG. 2 is an explanatory diagram of the internal space 30 of the shoe 20. As shown in FIG. 2, the inner peripheral surface of the inner space 30 of the shoe 20 includes a top surface 32, a bottom surface 36 corresponding to the inner bottom of the shoe 20, and a rear end surface 34. The three-dimensional shape data (shoe data) of the internal space 30 of the shoe 20 can be obtained by various methods as follows.
(A) After the three-dimensional measurement of the shoe mold (wood pattern, last) used for shoe manufacture, the measurement data is corrected as appropriate.
(B) The dimensions of the internal space of the shoe are measured with a measuring instrument, and the internal space is approximated by an appropriate three-dimensional shape.
(C) The coordinate value of the inner peripheral surface of the shoe inner space is measured using a coordinate measuring machine.
(D) The cross section of the shoe is measured using an X-ray CT apparatus or the like.
(E) The filling filled in the inner space of the shoe is taken out and the three-dimensional shape is measured.
(F) The three-dimensional shape of the outer shape (outer surface) of the shoe is measured, and the thickness of each member of the shoe is subtracted.

  The foot database 72 is a database that stores an identifier and foot data that is data of a three-dimensional shape of the foot in association with each other. FIG. 3 is an explanatory diagram of the foot 2. When the shoe is worn, the space between the fingertip 3 and the heel 6 is accommodated in the shoe interior space, the sole 5 is placed on the inner bottom of the shoe, and the upper 4 is covered with the shoe. The three-dimensional data (foot data) of the foot 2 can be obtained by measuring the three-dimensional shape of the foot 2 by an appropriate method. For example, in a state where the sole 5 is in contact with the transparent plate, a three-dimensional shape is measured from the back 4 side and the sole 5 side of the foot 2 to synthesize the measurement data.

  The control unit 60 is a computer that controls each of the devices 52, 54, 56, 58, 62, receives data, performs processing such as calculation, and outputs a result, and operates according to a program.

  The control unit 60 includes an insole design unit 64, a foot selection unit 66, and a database management unit 68. The insole design unit 64 supports the design of the three-dimensional shape of the insole laid in the shoe, and generates processing data for processing the insole. The foot selection unit 66 reads the foot data from the foot database 72 and inputs the read foot data to the insole design unit 64. The database management unit 68 manages addition, update, and deletion of data for the shoe database 70 and the foot database 72.

  The insole design system 50 may be configured to be accessible from an external terminal 90. For example, the communication device 58 is connected to the terminal 90 via a communication network such as a LAN or the Internet. A three-dimensional measuring device 92 is connected to the terminal 90 so that the three-dimensional shape data (foot data) of the foot measured by the three-dimensional measuring device 92 can be uploaded from the terminal 90 to the insole design system 50.

  Next, the operation of the insole design system 50 will be described with reference to the flowchart of FIG.

  (1) First, the shoe data of the selected shoe and the foot data of the user of the shoe are prepared (S10). Specifically, the insole design unit 64 receives input of foot data uploaded from the terminal 90. Alternatively, the foot selection unit 66 receives an input of the foot identifier from the terminal 90 or the input device 54, reads the foot data stored in association with the identifier that has received the input from the foot database 72, Input to the insole design section 64. The insole design unit 64 receives input of foot data from the foot selection unit 66. In this case, the foot data stored in the foot database 72 can be used.

  Further, the insole design unit 64 receives an input of a shoe model number from the terminal 90 or the input device 54, and reads shoe data stored in association with the model number of the received shoe from the shoe database 70.

  (2) Next, the three-dimensional shape of the gap formed between the inner peripheral surface of the inner space of the shoe and the foot is calculated (S12). Specifically, the insole design unit 64 has the foot 2 arranged in the shoe interior space 30 as shown in the explanatory diagrams of FIGS. 5 and 6 based on the foot data that has been input and the shoe data that has been read. The three-dimensional shape of the gap 38 formed between the inner peripheral surface of the internal space 30 and the foot 2 is calculated. At this time, a space simulation is performed so that the heel 6 of the foot 2 faces the rear end surface 34 of the inner space 30 of the shoe 20 and the upper 4 of the foot 2 faces the top surface 32 of the inner space 30 of the shoe. 38 three-dimensional shapes are calculated. The gap 38 is mainly formed between the bottom surface 36 of the internal space 30 and the sole 5 of the foot 2 and around the fingertip 3 of the foot 2.

  When the foot data is data of a three-dimensional shape of the foot while standing on a plane, the three-dimensional space 38 is considered in consideration of bending of the foot 2 along the inner space 30 of the shoe 20. The shape may be calculated. In consideration of the thickness of the socks, the space simulation may be performed assuming that a certain thickness is interposed between the shoe interior space 30 and the foot 2. When a part of the foot 2 slightly protrudes from the internal space 30, the gap 38 may be calculated on the assumption that the internal space 30 is deformed along the foot 2.

  The space simulation may be executed automatically by the insole design unit 64 or may be executed by the designer. For example, the designer may appropriately move the 3D image while viewing the internal space 30 and the 3D shape of the foot 2 displayed on the display device 52. In any case, the insole design unit 64 calculates the three-dimensional shape of the gap 38.

  (3) Next, the initial shape of the insole is determined (S14). Specifically, the insole design unit 64 determines the initial shape of the insole 10 based on the calculated three-dimensional shape of the gap 38, for example, as shown in the explanatory view of FIG. At this time, the insole design unit 64 generates data for displaying the initial shape of the insole 10 on the display device 52, transmits the data to the display device 52, and the initial shape of the insole is displayed on the display device 52. It may be.

  The initial shape of the insole 10 is determined according to a predetermined rule. For example, the shape of the back surface 10 t of the insole 10 is determined corresponding to the bottom surface 36 of the internal space 30 of the shoe 20. Even if the shape of the surface 10s of the insole 10 is the same as the three-dimensional shape of the gap 38 in the portion in contact with the sole 5, the three-dimensional shape of the gap 38 in the portion in contact with the sole 5 is deformed according to a predetermined rule. It may be a shape.

  (4) Next, an input of design parameters for changing the initial shape of the insole is received (S16). The design parameter can be changed in numerical value until it is determined (N in S18). Specifically, the insole design unit 64 receives an input of a design parameter for changing the initial shape of the insole 10 from the input device 54, and generates a three-dimensional shape obtained by correcting the initial shape of the insole according to the received design parameter. calculate. For example, the design parameters defined for the size, shape, position, etc. of the raised portions 10a, 10b, 10c and the recessed portion 10d of the surface 10s of the insole 10 shown in FIG. 7 are changed from the initial values. And the insole design part 64 changes the dimension, shape, position, etc. of the corresponding part according to the change of the design parameter. Depending on the design parameters, a difference may occur between the thickness of the insole before and after and on the left and right, and the surface 10s of the insole 10 may be inclined.

  By appropriately selecting design parameters, the optimum thickness and shape can be determined for each insole part, and the insole is optimally filled into the gap between the inner peripheral surface of the shoe inner space and the foot. As such, the insole can be designed. When the design parameters are selected by comprehensively considering the shape of the foot in the natural state and the movement of the foot when walking, the foot can be held in an ideal state by the combination of the insole and the shoe.

  After the insole design unit 64 receives input of design parameters, the insole design unit 64 generates data for displaying the corrected three-dimensional shape of the insole on the display device 52, and transmits the data to the display device 52. The corrected three-dimensional shape of the insole may be displayed on the display device 52.

  Moreover, the insole design part 64 can be made around the foot in a state where the insole 10 is laid on the shoe 20 by subtracting the three-dimensional shape of the insole 10 corrected according to the design parameters from the three-dimensional shape of the gap 38. A gap (gap when using the insole) may be calculated, and data for displaying the three-dimensional shape of the gap when using the insole or a representative value thereof on the display device 52 may be generated. In this case, the design of the insole 10 is facilitated by referring to the three-dimensional shape of the gap when using the insole displayed on the display device 52 or a representative value thereof.

  (5) When the design parameters are determined (Y in S18), machining data for machining the insole 10 is generated (S20). Specifically, when the insole design unit 64 receives an input for determining a design parameter (for example, input of a predetermined character) from the input device 54, the insole design unit 64 constitutes the insole 10 based on the determined three-dimensional shape of the insole 10. Processing data (for example, NC data used by the processing machine when cutting the base material of the insole) is generated and transmitted to the processing machine via the output device 56 and the communication device 58.

  For example, after processing irregularities on the surface of the base material using processing data (NC data), a finishing material is attached to the surface of the base material, and a reinforcing material is attached to the back surface of the base material to produce an insole. .

  Using the insole design system 50 described above, the shoe 20 selected by designing and manufacturing the insole 10 based on the shoe data of the selected shoe 20 and the foot data of the user of the shoe, The manufactured insole 10 can be combined. Considering the three-dimensional shape of the gap 38 formed between the inner peripheral surface of the inner space 30 of the shoe 20 and the foot 2 (or the gap 38 formed around the foot 2 in the inner space 30), By selecting the design parameters of the insole 10, the insole 10 can be designed so that the foot 2 is held in a desired state when combined with the shoe 20.

  The foot database 72 may store a foot identifier and a plurality of foot data (3D foot data) in association with each other. For example, the identifier of the foot and (i) the measurement data of the three-dimensional shape of both feet in a pressurized state in which the person to be measured stands on a plane (for example, a transparent plate) and the sole of the person to be measured is pressed against the plane. A certain pressure state foot data and (ii) measurement of the three-dimensional shape of both feet in a non-pressurized state where the foot of the person to be measured is in light contact with the plane or in a non-pressurized state where the foot is separated from the plane and floated in the air You may make it memorize | store and associate the non-pressurization state leg data which are data. In this case, the insole design unit 64 of the insole design system 50 can use a plurality of foot data in various modes as follows.

  In the first aspect, the insole design unit 64 of the insole design system 50 determines the initial shape of the surface of the insole so as to match the sole shape of the non-pressurized state foot data, Calculate the difference from the pressurized foot data, add the corrected component multiplied by the coefficient to the non-pressurized foot data, calculate the corrected 3D shape data, The initial shape of the insole surface is corrected so as to match the sole shape. The coefficient is set by a plurality of added design parameters so that different values can be selected depending on the foot region.

  In the second aspect, the insole design unit 64 of the insole design system 50 determines the initial shape of the surface of the insole so as to match the sole shape of the pressurized state foot data, and adds the non-pressurized state foot data to the added shape. Calculates the difference from the pressure state foot data, adds the correction component obtained by multiplying the calculated difference by the coefficient to the pressure state foot data, calculates the corrected 3D shape data, and calculates the sole of the corrected 3D shape data. The initial shape of the surface of the insole is corrected so as to match the shape. The coefficient is set by a plurality of added design parameters so that different values can be selected depending on the foot region.

  By using the foot data obtained by measuring the three-dimensional shape of the foot in both the non-pressurized state and the pressurized state, it becomes easy to produce an insole having an optimal shape according to individual differences and applications. Further, the correction component can be changed depending on the part of the foot, and the shape of the insole can be optimized for each part.

  The combination method of the shoe and the insole of Example 1 is configured as follows.

  The combination method of shoes and insoles includes (i) a first step of preparing a shoe database 70 in which shoe data, which is three-dimensional shape data of the internal space 30 of a plurality of shoes 20, is stored, and (ii) a shoe database. A second step of selecting one shoe from a plurality of shoes in which the shoe data is stored in 70, and reading the shoe data of the selected shoe from the shoe database 70, and (iii) the foot of the user of the selected shoe The foot 2 is arranged in the internal space 30 of the shoe 20 based on the third step of preparing foot data that is data of the three-dimensional shape of (2), and (iv) the read shoe data and the prepared foot data A fourth step of calculating the three-dimensional shape of the gap 38 formed around the foot 2 in the internal space 30 and determining the three-dimensional shape of the insole 10 so as to be disposed in the gap 38; v) The determined three-dimensional shape And (vi) a sixth step of combining the selected shoe 20 and the manufactured insole 10.

  According to the combination method of the shoe and the insole of Example 1, the foot 2 can be held in a desired state when the shoe 20 and the insole 10 are combined. The total balance can be optimized, and a combination of the shoe 20 and the insole 10 that is excellent in terms of function and design can be provided.

  In the third step, the foot data may be prepared by reading out the foot data of the user of the selected shoe from the foot database 72 in which the foot data is stored in advance. In this case, the foot data stored in the foot database 72 can be used for designing the insole 10.

  <Example 2> The shoe 20a of Example 2 is demonstrated referring FIG.8 and FIG.9. FIG. 8 is an explanatory diagram of the shoe 20a of the second embodiment. FIG. 9 is an explanatory diagram of a general shoe 20s.

  As shown in FIG. 9, the size of a general shoe 20s is adapted to the shoe 20s in a state where the sole 5 is placed on the inner bottom 22 of the shoe 20s (that is, on the inner peripheral surface of the inner space 30 of the shoe 20s). It is determined based on the foot length of the foot 2 and the foot circumference or the foot width, which are assumed to be appropriately along. Therefore, when the insole is laid on the shoe 20s whose size is selected in accordance with the foot length of the foot 2 and the foot circumference or the foot width, the foot 2 becomes cramped, and the insole design system according to the first embodiment is used. It may be difficult to design. Therefore, when laying an insole, it is necessary to select shoes 20s having a larger size.

  However, it is difficult to determine how large the size should be. In addition, the shoe 20s having a larger size is not preferable because the shoe 20s is not properly aligned around the foot 2.

  Therefore, as shown in FIG. 8, the shoe 20a of the second embodiment has a foot length, a foot circumference, or a foot width that is assumed to be suitable when worn with a reference insole 24 having a predetermined thickness. Based on the above, the size is determined. That is, the size of the shoe 20a is the foot length of the foot 2 assumed to be suitable for the shoe 20a in a state where the reference insole 24 is laid on the inner bottom 22 of the shoe 20a and the sole 5 is placed on the upper surface 26 of the reference insole 24. And the foot circumference or the foot width.

  Such a shoe 20a is used, for example, when manufacturing an ordinary shoe 20s as shown in FIG. 9 {a normal shoe type (wooden, last) of a predetermined thickness on a portion facing the inner bottom of the shoe. Manufacture is performed using a dedicated shoe mold with an auxiliary material (for example, about 3 mm of leather) attached or a shape corresponding to the state. The size of the manufactured shoe 20a is the same as the size of a general shoe 20s manufactured using a normal shoe mold.

  The reference insole 24 is assumed to be laid on the shoe 20a, and may or may not exist. For example, when the shoe 20s is manufactured by attaching an auxiliary material to a normal shoe mold, the reference insole 24 is a virtual one corresponding to the thickness of the auxiliary material.

  The reference insole 24 may be assumed to have an appropriate size and shape according to the shoe 20a, and may be disposed on the entire inner bottom 22 of the shoe 20a or may be disposed on only a part thereof. For example, when it is desired to narrow the internal space 30 of the shoe 20a, such as pumps or men's shoes, a half-type reference insole that faces only a part of the sole 5 (for example, the heel 6 side of the soil arch 8) It is also possible to assume a reference insole that is arranged on the inner bottom 22 of the shoe 20a so as to oppose only the heel and not on the fingertip 3 side.

  When the size of the shoe 20a of Example 2 is selected according to the foot length of the foot 2 and the foot circumference or foot width, the inner peripheral surface of the inner space 30 of the shoe 20a around the instep 4 and the heel 6 of the foot 2 The space corresponding to the reference insole 24 is ensured in the internal space 30 of the shoe 20a while maintaining a state in which it is properly aligned. Therefore, it is easy to design the insole so that the foot 2 is held in a desired state when combined with the shoe 20a. Moreover, the shoe 20a can easily select a size suitable for combining with the insole.

  <Summary> The insole design system described above can design the insole so that the foot is held in a desired state when combined with shoes.

  The present invention is not limited to the above embodiment, and can be implemented with various modifications.

  For example, the foot selection unit 66 and the foot database 72 may not be provided.
