Waterproof Shoe Structure
A waterproof shoe structure includes a sole, a vamp mounted on the sole, and a waterproof lining mounted on the vamp. The vamp is provided with a plurality of vent holes. The waterproof lining has a surface provided with a plurality of convex portions and a plurality of concave portions between the convex portions. Each of the convex portions is higher than each of the concave portions. Each of the convex portions is provided with a through hole connected to each of the vent holes of the vamp. The through hole of each of the convex portions and each of the vent holes of the vamp are integrated to connect an inner space of the vamp to an ambient environment.
The present invention relates to a shoe structure and, more particularly, to a waterproof shoe structure.
2. Description of the Related ArtA conventional waterproof shoe structure 60 in accordance with the prior art shown in
The primary objective of the present invention is to provide a waterproof shoe structure having breathable and waterproof functions.
In accordance with the present invention, there is provided a shoe structure comprising a sole, a vamp mounted on the sole, and a waterproof lining mounted on the vamp. The vamp is provided with a plurality of vent holes. The waterproof lining has a surface provided with a plurality of convex portions and a plurality of concave portions between the convex portions. Each of the convex portions is higher than each of the concave portions. Each of the convex portions is provided with a through hole connected to each of the vent holes of the vamp. The through hole of each of the convex portions and each of the vent holes of the vamp are integrated to connect an inner space of the vamp to an ambient environment. When rainwater drops, the rainwater directly flows down from the convex portions to the concave portions of the waterproof lining, without staying on the convex portions. When the rainwater drops onto the through hole of each of the convex portions, the rainwater does not enter the through hole of each of the convex portions by a capillary action. When the vamp is compressed by an external force, air in the inner space of the vamp is forced to flow through each of the vent holes of the vamp and the through hole of each of the convex portions, and is drained outward from the through hole of each of the convex portions into the ambient environment. When the vamp is released and restored to an original state after the external force disappears, the air from the ambient environment is introduced through the through hole of each of the convex portions and each of the vent holes of the vamp into the inner space of the vamp.
Preferably, each of the convex portions has a semispherical shape.
Preferably, the through hole of each of the convex portions is disposed at a vertical state.
Preferably, the through hole extends downward from a central position of a top face of each of the convex portions.
Preferably, the through hole of each of the convex portions has a small diameter.
Preferably, each of the vent holes extends through a whole thickness of the vamp, and the through hole extends through a whole thickness of each of the convex portions.
Preferably, the waterproof lining is mounted on a helmet.
Preferably, the waterproof lining is mounted on a raincoat.
According to the primary advantage of the present invention, the shoe structure has waterproof and ventilating functions by provision of the convex portions of the waterproof lining.
Further benefits and advantages of the present invention will become apparent after a careful reading of the detailed description with appropriate reference to the accompanying drawings.
Referring to the drawings and initially to
The vamp 12 is provided with a plurality of vent holes 121.
The waterproof lining 13 has a surface provided with a plurality of convex portions 131 and a plurality of concave portions between the convex portions 131. Each of the convex portions 131 has various models. Each of the convex portions 131 is higher than each of the concave portions. Each of the convex portions 131 is provided with a through hole 132 connected to each of the vent holes 121 of the vamp 12. The through hole 132 of each of the convex portions 131 and each of the vent holes 121 of the vamp 12 are integrated to connect an inner space of the vamp 12 to an ambient environment, to provide a ventilating effect to the shoe structure 1.
In the preferred embodiment of the present invention, each of the convex portions 131 has a semispherical shape.
In the preferred embodiment of the present invention, the through hole 132 of each of the convex portions 131 is disposed at a vertical state.
In the preferred embodiment of the present invention, the through hole 132 extends downward from a central position of a top face of each of the convex portions 131.
In the preferred embodiment of the present invention, the through hole 132 of each of the convex portions 131 has a small diameter.
In the preferred embodiment of the present invention, each of the vent holes 121 extends through a whole thickness of the vamp 12, and the through hole 132 extends through a whole thickness of each of the convex portions 131.
