Benefits of technology

[0005] The primary object of the present invention is to provide a friction sheet attached to a thin outsole so that the thin outsole has sufficient friction to prevent the wearers from slipping on roads.

Problems solved by technology

However, generally speaking, the stiffness of the material provides poor friction so that the manufacturers have to make deeper tread portion.
The tread portion provides poor friction when the surface that the outsole contacts is hard.
In addition, for high-heel shoes, the outsole is thin so that it is difficult to have deep grooves in the thin outsole.
Besides, the molds for making deeper tread portion are expensive.

Embodiment Construction

[0011] Referring to FIG. 1, the friction sheet 20 of the present invention comprises a fabric sheet 22 and a friction surface 22 is formed on a surface of the fabric sheet 22. The friction surface 22 may include ridges and grooves so as to provide sufficient friction with the roads and can be made by any proper material such as rubber. The fabric sheet 22 is made by non-woven fabric. The material of the friction surface 22 can be connected to the fabric sheet 22 by way of heat transferring so that the material is combined with the fabric sheet 22. The friction sheet 20 is attached to an outsole 10.

[0012] The color, shape and sizes of the friction sheets 20 can be made to meet different requirements so that the friction sheet 20 can also attract people's attention when walking or jogging.

[0013] As shown in FIG. 2, a shoe may be cooperated with two friction sheets 40 which are attached to the outsole 30 and the heel.

[0014]FIG. 3 shows that the outsole 50 includes a recess 52 define...

Abstract

A friction sheet includes a fabric sheet with a friction surface formed on a surface of the fabric sheet and the friction sheet is attached to an outsole so as to provide the outsole better friction and grasp ability. The friction sheets are especially designed to be cooperated with thin outsoles.

Description

FIELD OF THE INVENTION [0001] The present invention relates to an outsole with a friction sheet attached to the outsole so as to provide the outsole with higher friction. BACKGROUND OF THE INVENTION [0002] Conventional outsoles of shoes can be made by different materials for different purposes. For sport shoes or jogging shoes, the outsole is focused on flexibility so that the wearers feel comfortable during jogging. The material can be rubber or Polyurethane. If the outsole is used for high-heel shoes, the material will be Polyvinyl Chloride or TPR. Some shoes use wood or Acrylic to make the outsoles with high stiffness. However, generally speaking, the stiffness of the material provides poor friction so that the manufacturers have to make deeper tread portion. The tread portion provides poor friction when the surface that the outsole contacts is hard. In addition, for high-heel shoes, the outsole is thin so that it is difficult to have deep grooves in the thin outsole. Besides, th...
