Digital standard sample last

Abstract

The invention provides a digital standard sample last, wherein an entire last, a vertical section last and a cross section last are provided with digital standard samples; and the digital standard sample consists of a length of the last, a circumference of the last, a width of the last, and a size of the last body. The length of the last includes the length of a last bottom sample, a margin, positions of toes end points, the position of convex points of the thumb, the position of the convex points of the little finger, the position of the first metatarsophalangeal, the position of the fifth metatarsophalangeal, the position of the flank, the position of the heel center, and a rear tolerance. The circumference of the last includes: a metatarsophalangeal circumference, an instep circumference, a blanket circumference and a flank circumference; the width of the last includes a basic width, an inner width of the thumb, an outer width of the little finger, the inner width of the first metatarsophalangeal, the outer width of the fifth metatarsophalangeal, the outer width of the flank and a full width of the heel center; and the size of the last body includes the height of tiptoe, the thickness of head part, the height of the convex points of the heel, the height of the rear body, a protruding degree of the front palm, a concave degree of arch, the width of a last top, the length of the last top, and the inclined length of the last. The digital standard sample last is provided to designers of shoes by a convenient and rapid using method, so that the time of designing master lasts, upper samples and soles are saved and the designing process is simplified.

Description

Technical field [0001] The invention relates to a digital standard shoe last in the shoe industry. It is used to design and produce various shoe lasts, shoe uppers and shoe bottom components, and can also be used for teaching training. technical background [0002] Shoe last design is called the first element in the shoe industry. Its design success is not only related to the artistry and fashion of the shoe shape, but also related to the comfort, safety and health of the shoe. Because the shoe last is an irregular geometric body, the last is mainly curved, and the last has many characteristic parts and sizes, which is difficult to find and difficult to remember. It is difficult to find and measure accurately when designing, which makes the design procedure complicated. The designed product is not standardized or even deviation. It affects the standardization and digitization of shoe lasts, and even the comfort, health and safety of shoes. Summary of the invention [0003] The ...

Problems solved by technology

Since the shoe last is an irregular geometry, the surface of the last is mainly a curved surface, and there are many characteristic parts and sizes on the last surface, which are difficult to find and remember. It is difficult to accurately find and measure points during design, which makes the design process complicated. The designed products are not standardized or even deviated
