The strip surrounds and adheres to a peripheral surface of the midsole, a peripheral surface of the outsole, and a portion corresponding to the upper. The weight reduction effect is achieved by the midsole of the PU foam material.

Description

Rubber shoes

The present invention relates to a wearing article, and more particularly to a rubber shoe.

Referring to Figures 1 and 2, a conventional rubber shoe 1 includes a rubber sole 11, an upper 12 joined to the sole 11, and an insole 13 disposed within the upper 12. The sole 11 has a plurality of perforations 111 which are capable of reducing the overall weight of the sole 11.

However, although the perforations 111 can reduce the weight, when the insole 13 is adhered to the upper 12, the contact area is small, and it is easy to fall off, or the rubber is caused by uneven distribution of the perforations 111. The weight of the shoe 1 is uneven, causing discomfort for the user to wear.

Therefore, the purpose of the present invention is to provide a rubber shoe that can reduce weight.

Thus, the new rubber shoe is for the sole of a foot, and the rubber shoe comprises an upper, a midsole, a large bottom, and a rubber strip.

The midsole is a PU foam material and is adhered to the upper, and defines a space for the at least part of the foot to be placed with the upper.

The outsole is bonded to the midsole and is made of rubber.

The strip surrounds and adheres to a peripheral surface of the midsole, a peripheral surface of the outsole, and a portion corresponding to the upper.

The effect of the novel is that the weight reduction effect can be achieved by the midsole of the PU foam material.

Referring to FIG. 3, FIG. 4 and FIG. 5, an embodiment of the rubber shoe of the present invention is suitable for wearing a foot. The rubber shoe comprises a shoe upper 3, a midsole 4, a large bottom 5, and a rubber strip 6. And an insole 7.

The upper 3 includes a surrounding portion 31 surrounding the sole of the foot, a shielding portion 32 coupled to an upper periphery of the surrounding portion 31 for shielding a top surface of the sole portion of the foot, and a lower peripheral edge of the surrounding portion 31 and A connecting portion 33 spaced apart from the shielding portion 32 by a distance.

The midsole 4 is a PU foam material and is adhered to the connecting portion 33, and defines a space 40 for the at least part of the foot to be placed with the upper 3. The midsole 4 includes two spaced-apart surfaces 41, 42, a peripheral surface 43 connecting the surfaces 41, 42, and a plurality of foamed micropores 44 formed by foaming. The surface 41 is adhered to the connecting portion 33.

It should be noted that the midsole 4 and the upper 3 are not limited to being bonded, and in other aspects of the embodiment, they may be combined by sewing.

It should be noted that, in this embodiment, the material of the midsole 4 is polisport, and the material of the polisport is firstly foamed by MDI of high-density molecules and polyether, and then mixed by high-speed rotation and then foamed by PU. In addition to the advantages of the traditional PU foam material which is not easy to be deformed and highly elastic, it can be breathable, so that moisture is not easily accumulated in the midsole 4, which solves the disadvantage that the conventional PU foam material is easily hydrolyzed and hydrolyzed.

In addition, when the bonding, the pore diameter of the foaming micropores 44 is small, so that the contact area with another shoe material is large when bonding, and the bonding strength is increased, and the excess residual glue after bonding is also Part of the foamed micropores 44 penetrate into the midsole 4 and are less likely to overflow.

The outsole 5 is bonded to the midsole 4 and is made of a rubber material, and includes a top surface 51 adhered to the surface 42 of the midsole 4, a bottom surface 52 spaced apart from the top surface 51, and a bottom surface The top surface 51 and the peripheral surface 53 of the bottom surface 52 are connected.

The rubber material may be selected from natural rubber or synthetic rubber.

The strip 6 is wrapped around and adhered to the peripheral surface 43 of the midsole 4, the peripheral surface 53 of the outsole 5, and a portion corresponding to the upper 3. In the present embodiment, the strip 6 is a surrounding portion 31 that surrounds the upper 3 portion.

The insole 7 is adhered to the surface 42 of the midsole 4, but the manner of bonding is not limited to the manner of bonding. Alternatively, an alternative insole 2 may be used, which is inserted into the space 40 and disposed on the surface 41 of the midsole 4. .

When manufacturing, the upper 3 is first adhered to the surface 41 of the midsole 4, and a shoe last (not shown) for fixing the shape is built in the space 40, and then the midsole 4 is The surface 41 is glued and adhered to the outsole 5, and finally, the strip 6 is adhered along the peripheral surface 43 of the midsole 4 and the peripheral surface 53 of the outsole 5 to the corresponding upper upper 3 Thereby, the bonding strength of the upper 3, the midsole 4 and the outsole 5 is increased. After the above operation is completed, the vulcanization process is finalized, so that the outsole 5 is not easily aged and the elasticity is increased. Finally, the shoe last (not shown) is taken out from the space 40, and then hung on the rack to be cooled.

It should be noted that the insole 7 can be adhered to the midsole 4 first, and the vulcanization process is performed together with the outsole 5, the midsole 4, and the upper 3, or can be placed after vulcanization and cooling. Replacement insole 7.

Through the above description, the advantages of the foregoing embodiments can be summarized as follows: the midsole 4 of the PU material is used to reduce the weight and make the user comfortable to wear.

However, the above is only the embodiment of the present invention, and when it is not possible to limit the scope of the present invention, all the simple equivalent changes and modifications according to the scope of the patent application and the contents of the patent specification are still This new patent covers the scope.
