SHOE STRUCTURE

Abstract

A shoe structure includes an upper, an insole, a welt, a welt stitch, a sole, a sole stitch, and a cover strip. The upper has a bottom periphery with inner and outer sides, by which the insole and the welt are located respectively. The upper, the insole and the welt are combinedly stitched by the welt stitch. The sole is located below the insole and the welt, and stitched with the welt by the sole stitch. The cover strip is disposed on a top side of the welt and disposed with at least one stitching thread. The shoe structure can significantly enhance the sense of value to consumers on the condition of only slightly increasing the manufacturing cost, and has the advantages of durability, easy maintenance, aesthetic appearance and low cost.

DETAILED DESCRIPTION OF THE INVENTION

[0011] The structure and technical features of the present invention will be detailedly described hereunder by three embodiments and accompany drawings. As shown in FIGS. 1-2, a shoe structure 1 provided in accordance with a first embodiment of the present invention comprises an upper 10, an insole 15, a welt 20, a welt stitch 25, a sole 30, a sole stitch 35, and a cover strip 40.

[0012] The upper 10 is used to envelope the top and side surfaces of the user's foot, and has a top periphery 11 forming a shoe opening, and a bottom periphery 12. The upper 10 can be provided with a layer of inner lining to enhance comfort. However, the inner lining may be omitted in practice, and the upper 10 may be made by leather or weaving material.

[0013] The insole 15 is located by an inner side 121 of the bottom periphery 12 of the upper 10. The insole 15 has a flat portion 16 for supporting or contacting the sole of the user's foot, and a downwardly extending portion 18 extends downwardly from the flat portion 16. However, in another embodiment of the present invention, the downwardly extending portion 18 may be omitted.

[0014] The welt 20 is located by an outer side 122 of the bottom periphery 12 of the upper 10, and extends along the bottom periphery 12 of the upper 10 to form an annular shape.

[0015] The welt stitch 25 stitches the bottom periphery 12 of the upper 10, the downwardly extending portion 18 of the insole 15 and the inner periphery 21 of the welt 20 together, such that the upper 10, the insole 15 and welt 20 are fixedly and firmly combined together. In another embodiment of the present invention, the welt stitch 25 may be sewn with the flat portion 16 of the insole 15, not the downwardly extending portion 18.

[0016] The sole 30 is located below the insole 15 and the welt 20. To enhance the shock absorbing effect, a cork or foam cushion layer 32 can be additionally provided between the insole 15 and the sole 30. The cushion layer 32 is surrounded by the downwardly extending portion 18 of the insole 15, and sandwiched between the insole 15 and the sole 30.

[0017] The sole stitch 35 is used to stitch the welt 20 with the lateral edge of the sole 30 in a such way that the sole stitch 35 is exposed and visible on the top side 22 of the welt 20 and the bottom side 33 of the sole 30.

[0018] The cover strip 40 is disposed on the top side 22 of the welt 20 by adhesive. An inner periphery 41 of the cover strip 40 may be adhered with the upper 10. The cover strip 40 is disposed with two stitching threads 44 arranged parallel to each other. However, the two stitching threads 44 do not combine the cover strip 40 with any element, but are exposed on the top side 42 of the cover strip 40 to be visible by people. Because the cover strip 40 covers over the sole stitch 35, and more specifically covers over the exposed part of the sole stitch 35 on the top side 22 of the welt 20, only the two stitching threads 44 can be seen by consumers when the shoe structure 1 is viewed from top side thereof. Moreover, the outer periphery 43 of the cover strip 40 is arranged to be flush with an outer periphery 23 of the welt 20, and the appearance colors and textures of the cover strip 40 and the welt 20 are made to be the same or similar. As such, consumers can hardly acknowledge from the appearance of the shoe structure 1 that there is a cover strip 40 that is arranged on the welt 20, but will only recognize that two stitching threads 44 are arranged on a combination 45 of the cover strip 40 and the welt 20.

[0019] With the above-mentioned structural design, the shoe structure 1 provided by the present invention can lead consumers to recognize the combination 45 as the welt of the conventional shoe. Because the exposed two side-by-side stitching threads 44 can significantly enhance the sense of value of the product in the minds of consumers, provision and installation of the cover strip 40 will not increase too much manufacturing cost, and providing a cover strip 40 with stitching thread 44 is much simpler than the complicated manufacturing process of setting two rows of sole stitches 35, the shoe structure 1 of the present invention has great market potential. Further, when the sole 30 is worn out and needs to be replaced, the replacement task can be easily performed by removing the cover strip 40 and then the sole stitch 35 without the need of removing the upper 10, the insole 15 and welt 20, which are combined by the welt stitch 25. As such, the shoe structure 1 of the present makes maintenance relatively simpler and easier, thereby prolonging the service life. In another aspect, the design of the cover strip 40 may be modified to enhance aesthetic effect.

[0020] As shown in FIG. 3, a cover strip 40a of a shoe structure 1a in accordance with a second embodiment of the present invention is disclosed. The top side 42a of the cover strip 40a is provided with a plurality of rhinestones 50, thereby presenting a different pattern from the traditional shoe. As shown in FIG. 4, a cover strip 40b of a shoe structure 1b according to a third embodiment of the present invention is disclosed. The two stitching threads 44b on the cover strip 40b are continuously intersected with each other, which also presents a novel visual expression. In addition, the intervals of the stitching perforations of the stitching threads 44 can also be changed to enhance the sense of value. Such variations are not to be regarded as a departure from the spirit and scope of the invention, and all such modifications as would be obvious to one skilled in the art are intended to be included within the scope of the following claims.
