Definitions
- SHOE IN PARTICULAR SPORTS SHOE, AND METHOD FOR MANUFACTURING SUCH A SHOE
- the present invention relates to the technical field of footwear, in particular sports shoes, comprising two tubular textile elements forming part of the construction of the upper and possibly the sole of said footwear, and the methods of manufacturing such footwear.
- Conventional footwear generally includes an upper and a sole structure.
- the upper is secured to the sole structure and forms a void within the article of footwear to comfortably receive and secure a foot.
- the sole structure is secured to a lower region of the upper, and operatively disposed between the ground, and the upper.
- the sole structure may include an outsole and a midsole.
- the midsole often includes a polymeric foam material that absorbs shock with the ground upon impact to lessen the effects on the foot and leg during walking, running, or other ambulatory activities.
- the sole structure may also include a liner positioned near the bottom surface of the foot to enhance the comfort of the footwear.
- the soles are traditionally attached to the uppers using an assembly called Strobel during which the various sole elements (cleaning sole, midsole and outsole in particular) are assembled.
- Strobel an assembly used to attach the various sole elements (cleaning sole, midsole and outsole in particular) to the uppers.
- the manufacturing processes of a classic shoe require dozens of steps, and produce many scraps resulting from the cutting of materials.
- One solution is to eliminate the sewing steps needed to shape the initially planar upper in three dimensions.
- the upper is obtained from the assembly of one or a few parts, and no longer from multiple parts brought together by sewing.
- Footwear items comprising a tubular textile element comprising heat-fused textile portions forming at least part of the upper are thus known. It is thus sought to improve these footwear articles so that they are light, flexible and breathable, while
- SUBSTITUTE SHEET (RULE 26) offering satisfactory abrasion and tear resistance, and conforming comfortably to the shape of the foot.
- FR 3 098 690 Al describes the manufacture of a shoe from two superimposed textile tubular elements comprising at least partly heat-fusible yarns which are heat-melted during the thermoforming of the two textile tubular elements into an upper.
- FR 3 098 690 Al describes that it is possible to use different stitch patterns and different types of yarn (nature and/or color and/or transparency, cf. [0126]) but without specifying the type of yarn, nor its layout in the shoe.
- Such footwear despite a particular construction, must also offer varied designs respecting the technical criteria set out above, while limiting the aesthetic and/or functional component(s) necessary. to their manufacture.
- thermofusible yarns it may thus be desired to form one or more zones for viewing a particular portion of the article of footwear from the outside of the latter. It is thus proposed to melt thermofusible yarns and to form a transparent film-forming zone. Nevertheless, this type of film-forming zone decreases the breathability, and the flexibility of the upper when the thermofused monofilament yarns have a large diameter or the abrasion/tear resistance when the thermofused monofilament yarns have a small diameter. Moreover, when the upper comprises an inner layer and an outer layer comprising thermofusible threads, the latter adhere to the inner layer when they are heat-melted, further stiffening the treated zone of the upper.
