Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

This invention relates to a method for manufacturing shoe sole cushions, particularly to one for manufacturing a kind of a shoe sole cushion additionally adhered to a shoe sole and having a substratum coated with a layer of thermally solvent material such as glue, preventing a shoe from slipping.

2. Description of the Prior Art

Conventional shoes available on the market are mostly provided with shoe soles made of hard materials, such as plastic including PVC, TPR, EVA, etc. rubber, or wood. These hard materials may have the surface glossy and slippery with little anti-slipping function, and especially female shoes with high heels may have this kind of problem with a small dimension to touch on the ground. So some conventional shoe soles are additionally made with an anti-slipping material, which are generally made by means of an injection molding machine for forming the shoe sole with the anti-slipping material under it.

However, the anti-slipping material formed with the method described above have the following disadvantage.

1. A large injection molding machine has to be used for manufacturing a shoe sole with an anti-slipping material, so only a professional maker can manufacture it.

2. Manufacturing by an injection-molding machine involves complicated operational processes, needing a skilled operator, and subsequently increasing the cost.

3. Manufacturing by an injection molding machine can only use thermally solvent material, restricting materials usable.

4. Anti-slipping material cannot be combined with a shoe sole formed by an injection molding machine during its manufacturing process, so makers or consumers are impossible to add anti-slipping material to a finished shoe.

SUMMARY OF THE INVENTION

This invention has been devised to offer a method for manufacturing shoe sole cushions not only manufactured with simple processes, fastness, and convenience, but also applicable to various materials not restricted in a narrow scope, and bonding strength being quite strong not to fall off the sole easily to get extremely excellent anti-slipping effect.

The feature of the method for manufacturing shoe sole cushions with thermally pressed material includes various steps to prepare a substratum, to coat a thermally solvent material on the substratum to make a thermally pressed material, to cut the thermally pressed material to a cut shoe sole cushion with the same shape as a shoe sole, to place the cut shoe sole cushion on a shoe sole placed on a flat base of a thermally pressing device, and to melt and press the cut shoe sole cushion against the shoe sole for a certain time so as to adhere the cut shoe sole cushion to the shoe sole after hardened.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

A preferred embodiment of a method for manufacturing shoe sole cushions with a thermally pressed material in the present invention, as shown in FIG. 1, includes four steps of processes.

• • (a) A first step: Prepare a substratum 11; the substratum may be woven cloth, unwoven cloth, rubber, plastic such as EVA or any other proper materials, formed into a roll or an elongate flat strip.
  • (b) A second step: Coating a layer of thermally solvent glue 12 on the substratum 11 to form a thermally pressed cushion material 10; as shown in FIGS. 2 and 3, a layer of a thermally solvent glue 12 is coated on an upper surface of the substratum 11, possible to melt thermally at a proper temperature so that the substratum 11 with the layer of the thermally solvent glue 12 may make up the thermally pressed cushion material 10 wound up to a roll or flattened as an elongate flat strip. Further, the thermally pressed cushion material 10 is made to have the thickness of 0.5-2 mm, and can be added with anti-slipping agent, if necessary.
  • (c) A third step: Cut the thermally pressed cushion material 10; as shown in FIG. 4, the thermally pressed cushion material 10 is cut to have a proper corresponding shape to a show sole, becoming a cut shoe sole cushion 10a for the subsequent process.
  • (d) A fourth step: Thermally press the cut shoe sole cushion 10a on a show sole 20; as shown in FIG. 5, the cut shoe sole cushion 10a is placed just under a show sole and then heated up to the temperature 100-140° to let the cut shoe sole cushion 10a melted and then pressed with proper pressure against the shoe sole 20 for a preset period of time, say 5-10 seconds or so, until the melted cut shoe sole cushion 10a after hardens. Then the cut shoe sole cushion 10a naturally adhered to the shoe sole 20.

Next, the shoe sole 20 used in the preferred embodiment may be made of plastic such as PVC, TPR, EVA, rubber, or wood, possibly hard materials able to resist disfiguring caused by heat or pressure.

Further, as shown in FIG. 5, the cut shoe sole cushion 10a in this embodiment can be adhered on the shoe sole 20, by using a simple-structured thermally pressing device 30 composed of a flat base 31 and a thermal roller 32. Then the shoe sole 20 is first placed on the flat base 31, and the cut shoe sole cushion 10a is placed on the shoe sole 20 properly. Subsequently the thermal roller 32 is made to roll over the cut show sole cushion 32 against the shoe sole 20 so as to thermally melt the thermally solvent glue 12 and adhered to the shoe sole 20 after hardened.

Next, as shown in FIG. 6, Another, a second, thermally pressing device 30a can also be used for the method for manufacturing shoe sole cushions, composed of a flat base 33 and a thermal pressing plate 34. Then the shoe sole 20 is first placed on the flat base 33 and the cut shoe sole cushion 10a is placed properly on the shoe sole 20, so the thermally pressing plate 34 is rolled on the cut shoe sole cushion 10a to melt the thermally solvent glue 12 so as to adhere the cut shoe sole cushion 10a to the cut shoe sole 20 after hardened. Thus, the shoe sole 20 adhered with the shoe sole cushion 10a can be applied to various kinds of shoes including female shoes with high heels, as shown in FIGS. 7 and 8.

It is worth to mention that the method in the present invention has the following advantages.

1. The method of coating the thermally solvent glue 12 and of thermally pressed it on a shoe sole 20 can produce strong adherence between the shoe sole cushion 10a and the shoe sole 20 without possibility of falling off of the shoe sole cushion 10a, and subsequently securing the anti-slipping effect of the show sole 20.

2. The method in the invention does not need a costly injection molding machine, using a simple structured thermally pressing devices 30 or 30a mentioned above, saving the expenditure for its equipment.

3. The cut shoe sole cushion 10a can be adhered to a shoe sole after the shoe is finished wholly, so many optional chances can be selected for thermally adhering it on a shoe sole 20, not disturbing the manufacturing process of shoes.

4. The shoe sole cushion 10a can be combined with a shoe sole after a whole shoe is completed, and does not need a very high temperature for melting or the high pressure for pressing, so a user can get the shoe sole cushion 10a, cut it into a needed shape and melt and press it on a shoe sole by means of an electric iron.

5. The thermally solvent material 12 can be melted by the temperature 100-140° for pressed and adhered on the shoe sole, so the material of the shoe sole is not limited. If only a shoe sole 20 can endure the temperature 100-140° , any material of a shoe sole is usable for the method in the invention.

6. The thermally solvent material 12 of the cut shoe sole cushion 10a is first coated on the substratum 11, and then cut into a shape corresponding to a shoe sole, so its coating can be very even, not having an overly coated portion to cause plastic to overflow during heating up for melting, keeping a clean appearance of a shoe sole 20.

7. The substratum 11 can be added with anti-slipping agent, with many kinds being optional, so woven cloth, non-woven cloth, much elastic rubber and plastic can be available for the thermally solvent glue used in the method in the invention.

While the preferred embodiment of the invention has been described above, it will be recognized and understood that various modifications may be made therein and the appended claims are intended to cover all such modifications that may fall within the spirit and scope of the invention.
