Abstract
A sole structure of working shoe has an upper and a sole bonded by a stitching. A front portion according to the toes and extended from the surface of the sole has an overall size which is smaller than the sole. A gadroon forms along the outer periphery of the heel portion of the sole, and the gadroon has a quite depth for stitching so that the stitching stitches the sole under the upper along the contour of the sole. Furthermore, the gadroon is filled up with a welt, and the welt covers the stitching in the gadroon.
Description
- 1. Field of the Invention
- The present invention relates to a sole structure of working shoe, and more particularly to a sole that is stitched to an upper by a stitching along the contour of the sole with uniform stitching thickness in order to increase the strength of the sole structure.
- 2. Description of Related Art
- A conventional working shoe is designed for some dangerous working environments, like a welding plant, a high temperature environment, and a slippery condition.
- Referring to
FIG. 1 , a conventional working shoe has an upper 11, a middle sole 12, a lower sole 13, and aheel 14. The upper 11 is stitched to the middle sole 12 by astitching 15. The lower sole 13 gums to the middle sole 12, and at last theheel 14 gums to thelower sole 13. However, in some special environments, the working shoes have to provide waterproof, heatproof, greaseproof, and skidproof functions, but the binding method of conventional arts of working shoes has problems because the gum, bonding each layer of the sole, would be melted under the hot condition. Besides, in the other method of one conventional art that thelower sole 13 is stitched to the middle sole 12 by astitching 15, thestitching 15 is directly stitched along the contour of thelower sole 13 and is not covered so that thestitching 15 would be worn more often during the working in dangerous environments and it would lead to diminish the utility of the working shoes. - Taiwan Patent Application No. 89207471, which is filed by the present inventor, discloses a sole structure of working shoe. Referring to
FIG. 2 , the sole structure of working shoe has an upper 31 stitched to the periphery of a sole 32 by astitching 35. The sole 32 has aheel 33, according to the heel, and afront portion 34, according to the toes, which are extended from the surface of the sole 32. Each overall size of theheel 33 and thefront portion 34 is smaller than the overall size of the sole 32, and therefore thestitching 35 would be stitched along the edge of the sole 32. - To overcome the shortcomings, the present invention tends to provide a sole structure of working shoe to mitigate the aforementioned problems.
- In order to alleviate the aforementioned problems of the conventional arts, a sole structure of working shoe is designed meticulously. On the basis of inventor's practice according to the work, the present invention is useful, and it can solve the problems and limits of the conventional arts.
- To attain the above-stated object, in a sole structure of working shoe having an upper which is stitched to the periphery of the sole by a stitching, and the characteristic is that a gadroon forms along the outer periphery of a part of the sole where the heel portion extended. The result is that the gadroon has a quite depth for stitching so that the stitching stitches the sole under the upper along the contour of the sole with uniform stitching thickness.
- About a preferred embodiment of the present invention, the sole structure of working shoe having an upper which is stitched to the periphery of the sole by a stitching, and the characteristic is that a gadroon forms along the outer periphery of a part of the sole where the heel portion extended and a front portion according to the toes and extended from the surface of the sole has an overall size which is smaller than the sole. The result is that the gadroon has a quite depth for stitching and the stitching would be stitched along the contour of the sole with uniform stitching thickness.
- The present invention has improvements described as follows. First, the whole sole is bonded with the upper by a stitching, and therefore it would never have problems about the gum. Moreover, the stitching would not contact the ground directly and be protected from wear. Finally, the present invention not only improves the strength of the bond and prevents the damage of the wear but also makes the users more comfortable.
- In order to more fully explain the features and advantages of the present invention, the following preferred embodiments of a shoe according to the invention are described, as examples only without any limitative character, with reference to the accompanying drawings, in which:
-
FIG. 1 is a perspective view of a conventional sole structure of working shoe; -
FIG. 2 is a plan view of another conventional sole structure of working shoe; -
FIG. 3 is a perspective view of a preferred embodiment of the sole structure of working shoe of the present invention; -
FIG. 4 is a sectional view according to the heel of the shoe ofFIG. 3 ; -
FIG. 5 is a perspective view of another preferred embodiment of the sole structure of working shoe of the present invention; -
FIG. 6 is a front view of the shoe ofFIG. 5 . - Referring to
FIG. 3 , a sole structure of working shoe in accordance with the present invention has an upper 1 that is stitched to the periphery of the sole 2 by astitching 22 f. - The sole 2 has a lower sole 22, constructed by a
front portion 22 a, ashank 23, and aheel portion 22 b. Thefront portion 22 a, according to the toes, and theheel portion 22 b, according to the heel, are extended from the surface of the sole 2. Theshank 23 is hung in the air because theheel portion 22 b is thicker than thefront portion 22 a. Referring toFIG. 4 , agadroon 22 c forms along the outer periphery of a part of the sole 2 where theheel portion 22 b extended, and thegadroon 22 c has a quite depth for stitching so that thestitching 22 f stitches the sole 2 under the upper 1 along the contour of the sole 2 with uniform stitching thickness. - Referring to
FIGS. 5 and 6 , the sole structure of working shoe in accordance with the present invention wherein thegadroon 22 c is filled up with awelt 22 g. Thewelt 22 g is a decoration and makes the shoes fancy. Furthermore, thewelt 22 g can prevent thegadroon 22 c dirty and protect thestitching 22 f from wear. Finally, thewelt 22 g can reflect light in the dark to improve the safety of the users. - Referring to
FIG. 7 , the sole structure of working shoe in accordance with the present invention wherein thefront portion 22 a forms anannular portion 22 d surrounding aninner portion 22 e. Theannular portion 22 d is the surrounding part of thefront portion 22 a, and theinner portion 22 e is the other part, the inner part, of thefront portion 22 a. Theinner portion 22 e is thicker than theannular portion 22 d so that thestitching 22 f stitches the sole 2 under the upper 1 along the contour of the sole 2 with uniform stitching thickness. - About the said sole structure of working shoe of the present invention, the upper 1 is stitched to the sole 2 along the contour of the sole 2 by the
stitching 22 f with uniform stitching thickness so that the combinative strength of the upper 1 and the sole 2 is stronger and do not be degummed. - It is to be understood, however, that even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and function of the invention, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
