Benefits of technology

[0006] An object of the invention is to provide a shoe with an outsole which has an arrangement for protecting the outer peripheral surface of the outsole so that any finishing treatment for the connection of the outsole with an upper will not harm the outer peripheral surface of the outsole.

Problems solved by technology

However, due to the grinding process which can remove some part of the material from the marginal part of the outsole, the outsole is practically preformed with a size larger than that originally designed for the outsole, thereby wasting the material and increasing the manufacturing cost.
In addition, although a neat and tidy connection between the outsole and the upper can be accomplished through a grinding process, it is impossible to provide a pleasing outer appearance for the outer peripheral surface of the outsole due to the grinding process.
This is because the grinding process can damage or remove any decorative pattern formed on the outer peripheral surface of the outsole when grinding the connection between the outsole and the upper which is very close to the outer peripheral surface of the outsole.

second embodiment

[0021] Referring to FIG. 4, a third preferred embodiment of the present invention includes a shoe 30 which has the outsole 11 and an upper 32. The third preferred embodiment differs from the second preferred embodiment in that the third preferred embodiment does not include any component corresponding to the welt 222 of the The connection part 323 of the bottom end portion 322 of the upper 32 is sewn to an insole 321 which is attached to the top side 111 of the outsole 11 and the top side of the protection flange 114 which projects from the outer peripheral surface 113 of the outsole 11.

third embodiment

[0022] Referring to FIG. 5, a fourth preferred embodiment of the present invention includes a shoe 40 which comprises the outsole 11 and an upper 42. This embodiment differs from the third embodiment in that the upper 42 has a bottom end portion 423 which is not turned outward but includes a welt 422 of substantially L-shaped cross-section that is turned outward from the bottom end portion 423. The welt 422 has an upper end sewn to the bottom end portion 423 and a lower end sewn to an insole 421 which is attached to the protection flange 114 and the top side 111 of the outsole 11.

[0023] Referring to FIG. 6, a fifth preferred embodiment of the present invention includes a shoe 50 which comprises the outsole 11 and an upper 52 with a bottom end portion 521 turned inward and connected to a sole member 522. The bottom end portion 521 of the upper 52 incorporates a welt 523 of substantially L-shaped cross-section which is turned outward from the bottom end portion 521 and is attached to ...

Abstract

An outsole is provided with a protection flange projecting outwardly from the outer peripheral surface of the outsole and substantially flush with a top side of the outsole. An upper has a bottom end portion which includes a connection part extending laterally and outwardly from the bottom end portion thereof and attached to the protection flange and the top side of the outsole. Preferably, the connection part is an outwardly turned part of the upper or a welt. With the protection flange, the connection part is permitted to be ground so as to be flush with the protection flange without harming the outer peripheral surface of the outsole.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] This invention relates to a shoe, more particularly to an improvement relating to an outsole of a shoe. [0003] 2. Description of the Related Art [0004] Primary components of shoes generally include uppers and outsoles. In order to improve the appearance of shoes, various designs have been provided for connections between outsoles and uppers. There are shoes which have an outsole attached to an upper with an outwardly turned end portion or an outwardly turned welt member. In making such shoes, since it is difficult to make a connecting part of the upper flush with a connecting part of the outsole, a grinding process is usually employed to grind the connecting parts so as to provide a neat and tidy connection between the outsole and the upper. [0005] However, due to the grinding process which can remove some part of the material from the marginal part of the outsole, the outsole is practically preformed with a size la...
