The present invention relates to a vamp of a shoe, and more particularly to a method for fixing a decorative member on a vamp of a shoe in a three dimensional manner.
Shoes are indispensable to out daily life. Among them, there is a kind of shoe whose vamp and liner are both made of cloth, which makes the wearer's feet feel more comfortable as compared to other shoes.
Please refer to
It is to be noted that, in the step 1 as shown in
With this method, the decorative members 14 cannot be pressed at one sitting, which complicates the procedures for pressing the decorative members 14. Besides, pressing the decorative member 14 which has been formed and cooled off directly onto the vamp 10 makes it difficult for the decorative member 14 to fit well against the vamp 10, and as a result, the decorative member 14 is more likely to falling off.
The present invention has arisen to mitigate and/or obviate the afore-described disadvantages.
One objective of the present invention is to provide a method for fixing a decorative member on a vamp of a shoe in a three dimensional manner, wherein the step of pressing decorative members allows the decorative members to be simultaneously pressed onto the upper surface and the lateral surface of the vamp, which substantially reducing shoe manufacturing time.
To achieve the above objective, a method for fixing a decorative member on a vamp of a shoe in a three dimensional manner in accordance with the present invention is provided, wherein the vamp includes an upper surface, a lateral surface and a bottom surface, and the method comprises:
a step of pressing including: preparing a sole mould and a decorative-member mould, wherein the sole mould includes a sole mould cavity and a first abutting surface, the decorative-member mould includes a decorative-member mould cavity and a second abutting surface, filling the sole mould with a semi-cured sole, filling the decorative-member mould with a semi-cured decorative member, pushing the decorative-member mould against the upper surface or the lateral surface of the vamp, with the second abutting surface pressing against the upper surface or the lateral surface to attach the semi-cured decorative members to the upper surface or the lateral surface; pushing the sole mould against the bottom surface with the first abutting surface pressing against the bottom surface to attach the semi-cured sole to the bottom surface; and
a step of heating including: heating the vamp to melt the semi-cured sole and decorative members; the decorative members and the sole are cured when heated to a predetermined temperature.
Preferably, the semi-cured sole and the decorative member are made of a material selected from a group consisting of rigid polyurethane, casting and polyurethane.
Preferably, the sole mould and the decorative-member mould are made of a material selected from a group consisting of polyurethane, thermoplastic polyurethane and silicon.
Preferably, the sole mould and the decorative-member mould are soft or rigid moulds.
Preferably, in the step of heating, the semi-cured sole and decorative members are heated to 30-80° C. when they are heated to a melted state.
Preferably, the predetermined temperature is 60-120° C.
These together with other objects of the invention, along with the various features of novelty which characterize the invention, are pointed out with particularity in the claims annexed to and forming a part of this disclosure. For a better understanding of the invention, its operating advantages and the specific objects attained by its uses, reference should be had to the accompanying drawings and descriptive matter in which there are illustrated preferred embodiments of the invention.
The present invention will be clearer from the following description when viewed together with the accompanying drawings, which show, for purpose of illustrations only, the preferred embodiment in accordance with the present invention.
Referring to
The vamp 20 includes an upper surface 21, a lateral surface 22 connected to the upper surface 21, and a bottom surface 23. The upper surface 21, the lateral surface 22 and the bottom surface 23 define a 3 dimensional shape of a shoe.
The sole 30 is heated by a sole mould 31 and then connected to the bottom surface 23 of the vamp 20. The sole mould 31 includes a sole mould cavity 311 for accommodation of the sole 30, and a first abutting surface 312 for abutting against the bottom surface 23.
The decorative member 40 is heated and connected to the upper surface 21 or/and the lateral surface 22 of the vamp 20 by a decorative-member mould 41. The decorative-member mould 41 includes a decorative-member mould cavity 411 for accommodation of the decorative member 40, and a second abutting surface 412 for abutting against the upper surface 21 and the lateral surface 22 of the vamp 20.
Referring to
a step 1 of pressing, as shown in
a step 2 of heating, as shown in
The predetermined temperature is 60-120° C., and the semi-cured sole 30 and decorative members 40 are heated to 30-80° C. when they are heated to a melted state.
It is to be noted that the method for fixing the decorative member on the vamp in a 3 dimensional manner in accordance with the present invention allows the decorative members 40 and the vamp 20 to be formed in the same step. In the step 1 of pressing, a plurality of decorative members 40 can be simultaneously formed on the upper surface 21 and the lateral surface 22, and the sole 30 can also be formed on the bottom surface 23 simultaneously with the decorative members 40. Not only the decorative members 40 can be formed in the same step, but also the sole 30 can be formed in the same step along with the decorative members 40. Or, the sole 30 can also be formed in a separate step from the decorative members 40, so that the step for pressing the decorative members 40 and the step for connecting the sole 30 are simplified.
Referring then to
With the method for fixing the decorative member on the vamp in a 3 dimensional manner in accordance with the present invention, the decorative members 40 and the sole 30 can be formed on the upper surface 21, the lateral surface 22 and the bottom surface 23 of the vamp 20 simultaneously in the same step, which simplifies the steps for forming the decorative members 40 and the sole 30, consequently substantially reducing the necessary time for manufacturing shoes.
While we have shown and described various embodiments in accordance with the present invention, it is clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
