Abstract

PURPOSE:To unnecessitate any exchange by providing a pump inside the main body of an insole for sucking air from a part of the main body of the insole and discharging air to any other part, and composing the device of fine holes formed inside the main body of the insole for moving air from the pump to a discharge port. CONSTITUTION:When the heel of a foot gets away from a main body 12a of the insole, air is sucked from a part B of the main body 12a of the insole, air inside shoes is guided through a tube 12b into a hollow elastic object 12d as the pump, and this hollow elastic object is expanded. During walking or running, the main body 12a of the insole is pressed from the upside by the heel of the foot, the hollow elastic object 12d as the pump is recessed through the main body 12a of the insole, air is passed through fine holes 12e air is moved to a discharge port 12f. Thus, the shoes provided with a malodor preventing means, for which it is not almost necessary to be exchanged, can be provided.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a malodor preventing device for shoes, and more particularly to a malodor preventing device for shoes which constantly refreshes the air in the shoes to prevent malodor.

[0002]

2. Description of the Related Art Conventionally, a general method for preventing a malodor in a shoe is to place an insole containing activated carbon inside the shoe and absorb the composition that causes the malodor contained in the air in the shoe with the activated carbon. It was done by

[0003]

However, according to this method, the insole must be replaced every time when the function of the activated carbon deteriorates with the passage of time and the composition causing the bad smell cannot be absorbed. However, there is a drawback that it costs money every time it is replaced.

Accordingly, it is an object of the present invention to provide a malodor prevention device for shoes which hardly needs to be replaced.

[0005]

In order to achieve the above object, the present invention provides a main body of an insole and a main body of the insole which sucks air from a part of the main body of the insole and discharges the air to another part. Another object of the present invention is to provide a malodor prevention device for shoes, which comprises a pump and a pore formed in the insole body for transferring air from the pump to the outlet.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings. FIG. 1 is a schematic cross-sectional view showing the basic structure of the present invention, FIG. 2 is an enlarged vertical cross-sectional view showing the basic structure of the malodor preventing means used in the present invention, and FIG. Is a figure,
FIG. 4 is a sectional view for explaining the configuration and operation of the pump used in the malodor prevention means, FIG. 5 is a sectional view showing another embodiment of the malodor prevention means, and FIG. 6 is a malodor. FIG. 7 is a cross-sectional view showing still another embodiment of the prevention means, and FIG.
FIG. 8 is a sectional view showing still another embodiment of the malodor preventing means.

First, the basic structure of the present invention will be described with reference to FIG. In FIG. 1, a shoe 10 has a heel portion 1
The malodor preventing means 12 of the present invention is placed in the shoe in the form of an insole in this embodiment, which is composed of a sole 10a having 0b and an upper skin portion 10c. Offensive odor prevention measures 1
2, which will be described later in detail, supplies fresh air to the toe side of the shoe to circulate the air in the shoe (exchanging fresh air and air containing bad smell) to prevent bad smell. is there.

Next, referring to FIGS. 2 and 3 showing the basic structure of the malodor preventing means, the malodor preventing means 12 has an insole body 12a having a somewhat flexible composition. Tube 12b forming a pump in the
And a hollow elastic body 12d. The pump is shaped to be centered approximately above the heel of the shoe. The tube 12b is made of a metal or plastic rigid material that does not deform even when an external force is applied, and the hollow elastic body 12d is flexible such as rubber that is dented when the external force is applied and swells when the external force is released. Made of material. The tube 12b is arranged so that one end thereof projects from the end of the insole body 12a (it does not necessarily have to project as shown in the figure, and may be in the same plane as the surface of the insole body, or may be the insole body). May be located at a position recessed from the surface of the tube, and for convenience of explanation, the expression of “projection” will be used below, but it should be interpreted as described above). It is led to the outlet 12c provided. The outer end of the hollow elastic body 12d is adhered to the outer peripheral wall of the tube 12b between the protruding end and the outlet 12c in an airtight state with, for example, an adhesive.

The inner end portion of the hollow elastic body 12d is connected to a pore 12e provided in the insole body 12a. The pore 12e extends from the hollow elastic body 12d to the toe side of the shoe and is branched at the toe portion. It becomes a manifold and is connected to, for example, a plurality of outlets 12f arranged at corresponding positions between the toes (FIG. 3).

Next, the operation of the pump will be described with reference to FIGS. 2 and 4. FIG. 4 shows a state in which the heel of the foot presses the insole body 12a from above while walking or running (for example, force F) to dent the hollow elastic body 12d of the pump through the insole body 12a. 2 shows a state in which the heel of the foot is separated from the insole body 12a and the hollow elastic body 12d is returned to the original state. As shown in FIG. 4, when the hollow elastic body 12d is dented, the hollow elastic body 12d closes the outlet 12c of the tube 12b.
The air in 2d is pushed toward the small hole 12e as shown by the arrow A, and is ejected through the small hole 12e from the outlet 12f into the shoe. Next, when the heel of the foot separates from the main body of the insole, as shown in FIG. 2, the hollow elastic body 12d swells from the dented state, and as shown by an arrow B, the air in the shoe is passed through the tube 12b and inside the hollow elastic body 12d. Lead to. In this way, the air in the shoe can be circulated, with some of the air taken into the tube coming from the outside to the inside of the shoe, while some of the air expelled into the shoe is taken up by the shoe. Brought to the outside. In this way, air is constantly exchanged inside and outside the shoe to prevent odors.

Next, referring to FIG. 5, there is shown a sectional view of another embodiment of the malodor preventing means of the present invention. In this example,
The insole body 12a has a long length so that its rear end can be raised along the rear wall of the shoe, and the tube 12
b is also formed correspondingly long. In the illustrated example, the inlet of the tube 12b is provided at a position (outside) facing the rear wall of the shoe, but it may be opened at the top end of the insole, or provided inside the insole body. Is also good. Further, the tip of the tube 12b may be formed into a plurality of branched manifolds.

FIG. 6 shows still another embodiment. In this embodiment, a hole is formed in the rear wall of the shoe, and the tip of the tube 12b is inserted into the hole.
In this embodiment, much external air is provided within the shoe.

FIG. 7 shows still another embodiment. In the main body of the insole described above, the portion where the pump is arranged becomes thick, which may impair comfort. In this embodiment, the heel portion 10b is formed with a recess, and the pump portion is housed in that portion. Further, the malodor preventing means may be formed as an insole, but it may be formed integrally with the shoe by being attached to the shoe sole with an adhesive.

[0014]

As described above, according to the present invention,
The result is a shoe with odor control that requires little replacement.
