Technical Field

The invention relates to the technical field of shoe tree design, in particular to a method for quickly representing a shoe tree structure.

Background

The last is the soul of the shoe, and the body representing the last is the first step of shoe-like modeling design and is also the most important step. In the process of representing the last type, the body proportion, the line structure, the head type change and the like are directly related to the quality of shoe sample design.

In the design process of the shoe pattern, a last structure of a shoe pattern to be designed, such as a flat-heel last, a low-heel last, a middle-heel last and a high-heel last, needs to be drawn on a paper. After the shoe last type structure to be designed is determined, the shoe money in the brain of a designer is actually displayed in a paper piece, the effect or style of the shoe money is determined, and finally, the shoe money is carefully knocked out and then is colored. At present, a shoe money designer can only design 1 pair of shoes in 1 day, and the shoe money designer can not meet the market requirement. Because sales of footwear are affected by seasons, designers are required to design hundreds of shoe money in a short time and to sort out the explosive money that may exist in sales in a given season. Therefore, the time-efficiency requirement on a designer is higher, and the design quantity is larger. Therefore, how to express the desired lasting structure on the paper rapidly and the lasting structure should be presented with high quality to ensure the quality of the shoe design is a problem to be solved by those skilled in the art.

Chinese patent publication No. CN105595532A discloses an independent last and a high-heeled shoe for making shoes, which comprises an integrally formed last body simulating a human foot, wherein a forefoot curved surface, a lumbar curvature and a heel curved surface are formed on the bottom surface of the last body, and the height L1 of the tail end of the heel curved surface relative to the landing point is 80 mm. The last is a high heel last, the heel of which has a height L1 of 80mm compared to the landing point. However, if the height L1 of the heel relative to the landing point is any height, the designer cannot quickly determine the whole last structure corresponding to the height of the heel, so that the designer cannot conveniently draw on a paper, and the quantity and quality of the shoe designed by the designer cannot meet the requirement, and thus needs to be improved.

As shown in fig. 1 to 5, a method for rapidly representing a last structure includes the following steps:

step 1, determining a horizontal line and dividing each feature point: a horizontal line with the length of 150mm-160mm is drawn on a paper, the two ends of the horizontal line are respectively used as the head part 1 and the heel part 2 of the last body, and the characteristic points are marked as follows:

the landing points 9: a second base point 7 is marked vertically downwards 2 mm;

step 2, drawing an arc line at the bottom of the shoe last: sequentially connecting the first last point 4, the first base point 6, the landing point 9, the third base point 8 and the heel high point 3 by adopting connecting lines with natural shapes to form a last bottom arc line;

step 3, drawing an arc line of the heel: a heel auxiliary line 10 with the length of 47mm is vertically drawn upwards at one end of the arc line of the bottom of the last close to the heel high point 3, and the following key points are determined by using the heel auxiliary line 10:

heel start point 11: one end of the heel auxiliary line 10, which is 5mm away from the arc line of the bottom of the last, is marked, and the heel starting point 11 is positioned on the arc line of the bottom of the last;

first connection point 12: marking the position 5mm away from one end of the arc line of the bottom of the shoe tree on the auxiliary line 10 of the heel;

heel turning point 13: taking a quarter of the heel auxiliary line 10, the quarter being a quarter of the length of the entire heel auxiliary line 10 from the bottom arc of the last, the quarter being marked as extending perpendicularly outward by 1mm (outward in this embodiment, meaning toward the direction away from the last);

heel termination point 15: marked at a position 8mm away from one end of the heel auxiliary line 10 far away from the bottom arc line of the shoe tree in the horizontal direction, and the heel termination point 15 is arranged in the direction close to the shoe tree;

step 5, drawing a tarsal dorsum line: an auxiliary tarsal line 17 perpendicular to an end of the auxiliary heel line 10 away from the bottom arc of the last is made, and the following key points are determined by using the auxiliary tarsal line 17:

heel point 18: taking a three-eighths point of the horizontal line, wherein the distance between the three-eighths point and the root is three-eighths of the length of the whole horizontal line;

intersection point 19: a position where the heel point 18 is vertically upward to make a vertical line, and the vertical line intersects with the tarsal back auxiliary line 17;

tarsal onset 20: upward 15mm from the point 19 of the uniform orifice perpendicular to the auxiliary line 17 of the dorsum tarsi;

dorsum inflection point 21: connecting the dorsum tarsal starting point 20 with the front end point 5 of the last, making a connecting auxiliary line, and taking a position, which is vertically 15mm below the connecting auxiliary line, of the middle point of the connecting auxiliary line;

the dorsum tarsal origin 20, the dorsum inflection point 21 and the last feature point 16 are connected in sequence by natural-shaped connecting lines to form a dorsum tarsal line.

Step 6, line smoothing: and (4) trimming the lines which preliminarily form the shoe last type, so that the connection between the lines is excessively smooth and natural.

In practical applications, if the designer uses the method of the present invention, the designer can quickly and simply draw the desired flat-heel last type, low-heel last type, middle-heel last type and high-heel last type according to the heel height desired by the designer. The last structure of the shoe money to be designed drawn by the scheme can quickly and directly express the corresponding last on a paper piece according to different heel heights, so that a designer can conveniently carry out subsequent heel matching, bottom matching and side sample design.

Because the inspiration of the designer is sudden and the paper and the pen are visible everywhere, the designer can quickly change the mind into paper after using the method, and the good characteristics of convenience and quickness are incomparable with the computer design. Therefore, in the field of shoe design, direct drawing on paper is adopted at present.

As shown in fig. 6 and 7, schematic diagrams of a flat heel, a low heel, a middle heel and a high heel are shown, and it can be seen that: the dorsum inflection point 21, the toe point 5 and the landing point 9 are substantially stationary in the variation of the heel height of the paper. Therefore, the change of heel height will be driven synchronously

Further, when the last structure is a flat heel last, the method further comprises the following root expression steps:

step 7.1, drawing a middle bottom line 22: drawing the arc line 1.5mm away from the bottom of the shoe tree at equal intervals downwards;

step 7.2, drawing a big bottom line 23: drawing the arc line of the last at 2.5mm downward at equal intervals, wherein the cut-off point of one end of the big bottom line 23 is a quarter of the horizontal line, and the distance from the quarter of the horizontal line to the root is a quarter of the length of the whole horizontal line;

step 7.3, drawing a horizon 24: the horizontal line 24 is a horizontal tangent line at the bottom of the big bottom line 23;

step 7.4, drawing the heel 25: the height of the bottommost end of the heel 25 needs to be raised by 1mm on the basis of the horizon 24, a heel base line 14 is drawn according to the height, and two ends of the heel base line 14 are respectively and vertically connected with the middle sole line 22 and the large sole line 23 through connecting lines.

Furthermore, when the characteristic points and the key points are drawn and connected, the characteristic points and the key points need to be light and heavy, and lines need to be integrally smoothed after connection is completed.

Furthermore, the last type structure drawn by the method is half-shaped, and after shoe money is designed, the designed shoe money picture can be imported into ShoesMaster software in a photographing mode. Because the ShoesMaster software takes a half of a half panel, the structure of the shoe last drawn by the method is consistent, after the software is introduced, the peripheral length of the software is adjusted, and the shoe last is matched with the shoe last by one key, so that the plate making process (namely the next process after shoe style design) can be realized.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention, and they should be construed as being included in the following claims and description.
