Abstract
A non-slip sole structure of anti-slip shoes used for stream trekking and fishing is made of a material with a large coefficient of friction such as unwoven fabric and having regular or irregular hollow grooves formed at predetermined positions of the sole to match with corresponding bumps, formed at the bottom of a shoe body. When the sole is combined with the bottom of the shoe body, the bumps at the bottom of the shoe body bottom are passed through the hollow grooves of the sole respectively and slightly protruded and exposed to achieve a more secured embedded positioning effect and provide an appropriate bending and extending deformation margin to the sole to avoid a stripping problem effectively. The bumps at the bottom of the shoe body are slightly protruded from the sole surface to improve an anti-slip grip effect and avoid wearing out the sole too quickly.
Description
- 1. Field of the Invention
- The present invention relates to a non-slip sole structure, and more particularly to the non-slip sole structure for shoes applied for stream trekking, rock fishing or fish catching to overcome the conventional structure having the drawbacks of easy stripping, poor anti-slip effect and high wear out rate, and the non-slip sole structure of the invention can improve the connection between a sole and a shoe body and provide a better anti-slip effect.
- 2. Description of the Related Art
- When conducting activities such as stream trekking, rock fishing or fish catching, people have safety concerns and may slip easily due to unstable equilibrium or mosses and algae formed on rocks under a stream or wave blocks at a seashore, and thus it is necessary to wear stream trekking shoes, barreled boots, rain boots, jumpsuit specified shoes or the like. In general, a special design of a non-slip sole structure of a sole is used to improve the friction when stepping on the rocks or wave blocks, so as to reduce the chance of slipping or falling accidentally.
- In the design of special ,shoes of this sort, a sole is usually made of a material having a large coefficient of friction such as an unwoven fabric, and the sole is combined with a shoe body by adhering a glue, and a non-smooth surface of the material such as the unwoven fabric can provide a larger friction, so that when a user steps or walks on the slippery rocks or wave blocks, the shoes can provide an appropriate anti-slip effect.
- However, the structural design of the aforementioned conventional shoes still have the following drawbacks
- 1. The sole is made of unwoven fabrics and thus has a loosened structure and a poor durability, so that the sole may be worn out easily, although it can achieve the expected anti-slip effect.
- 2. The sole is in a flat shape, and comes with a rough surface to achieve a larger friction and resistance for an appropriate anti-slip effect, but the anti-slip function varies with the environment, particularly if the rocks or wave blocks are large in size, the grip of the sole will be insufficient, and the anti-slip effect will be affected seriously.
- 3. The sole and the shoe body are combined by a glue, so that the gluing position is at a planar contact interface between the sole and the shoe body only, but the sole is made of a relatively hard material. As a result, the glued sole cannot bear bending, and may he stripped easily after being worn for some time.
- In other words, the conventional non-slip sole structure still have drawbacks that require feasible solutions and further improvements.
- In view of the existing problems and drawbacks of the conventional non-slip sole structure, the inventor of the present invention based on years of experience in the related industry to conduct extensive researches and experiment, and finally developed a non-slip sole structure of the present invention to overcome the problems and drawbacks of the prior art.
- Therefore, it is a primary objective of the invention to provide a non-slip sole structure that can achieve a more secured combination effect between a sole and a shoe body and avoid a stripping problem to extend the life of non-slip shoes.
- Another objective of the present invention is to provide a non-slip sole structure that can improve the overall grip to enhance the stability of stepping and walking and provide a better wear, in addition to the more secured combination between the sole and the shoe body.
- To achieve the foregoing objectives, the present invention provides a non-slip sole structure comprising a plurality of regular or irregular hollow grooves formed at predetermined positions of a sole respectively, and matched with a plurality of corresponding bumps formed at the bottom of a shoe body respectively, such that when the sole is combined with the bottom of the shoe body, the bumps at the bottom of the shoe body are passed through the hollow grooves of the sole respectively and slight protruded and exposed to the outside, so as to achieve a more secured embedded positioning effect and provides an appropriate bending and extending deformation margin to the sole to improve the stripping problem. Since the bumps at the bottom of the shoe body are slightly protruded from a surface of the sole, the anti-slip grip can be improved, and a quick worn-out of the sole can be avoided.

During the adhesive operation, the glue is applied to a contact surface between the sole 10 and the bottom of theshoe body 20, and also to a contact interface between thebumps 21 and thehollow grooves 11, or the sole 10 is formed first and then placed in a mold for performing an injection molding operation of theshoe body 20 to substitute the gluing method, but it is not the target of the present invention, so that will not be described here. The material for forming theshoe body 20 is circulated to thehollow grooves 11 of the sole 10 to form thebumps 21, so as to constitute the non-slip sole structure in accordance with a preferred embodiment of the present invention. - With the aforementioned structural design, the
hollow grooves 11 of the sole 10 together with thebumps 21 of theshoe body 20 can achieve a multi-directional combination and a position-limit effect, and the design of thehollow grooves 11 can provide a better bending and extending deformation margin of the sole 10 for a bendable function to avoid a possible stripping problem effectively and extend the wearing life of the non-slip sole structure. In the other hand, thebumps 21 formed at the bottom of theshoe body 20 are slightly protruded from a surface of the sole 10, so that the grip and anti-slip effect can be enhanced to improve the anti-slip performance.
