Description

[Technical field]

[0001] The present invention particularly relates to footwear that absorbs carbon dioxide by utilizing the force of the wearer's walking, etc. [Background technology]

[0002] In recent years, efforts to reduce carbon dioxide emissions have been attracting attention worldwide. However, conventional methods for reducing carbon dioxide emissions include the use of large-scale equipment to absorb carbon dioxide, which requires a large investment and is difficult for individuals to implement. In addition, when using equipment, the equipment itself emits carbon dioxide, so the efficiency of carbon dioxide reduction is insufficient. Therefore, a simple configuration is needed that allows even individuals to contribute to carbon dioxide reduction. [Prior art documents] [Patent documents]

[0012] Footwear Hereinafter, footwear according to an embodiment of the present invention will be described with reference to the drawings. The footwear according to the present invention absorbs carbon dioxide by utilizing the force of the wearer's walking, etc. The footwear is mainly what is called a shoe that is worn on a person's feet, and may be any type of shoe, such as leather shoes, sneakers, sandals, boots, or boots.

[0013] As shown in Fig. 1, footwear 1 mainly comprises an upper part 2 and a sole part 3. The upper part 2 is a part that constitutes the upper part of footwear 1, and has an opening into which the wearer's foot is inserted. In the present invention, the configuration of the upper part 2 is arbitrary, and any suitable known technology may be adopted.

[0014] 1 to 3, the sole portion 3 is a portion connected to the lower portion of the upper portion 2, and constitutes the bottom surface of the footwear 1. The sole portion 3 has elasticity, and is sandwiched and compressed between the upper portion 2 and the ground when the footwear 1 is in use, that is, for example, when walking or running.

[0015] The sole portion 3 mainly includes an air intake 31, an air chamber 32, a carbon dioxide absorption portion 33, and an exhaust port 34. The air intake 31, the air chamber 32, the carbon dioxide absorption portion 33, and the exhaust port 34 are connected in this order directly or via an appropriate connection path.

[0016] The air intake 31 is a hole that communicates the air chamber 32 with the outside. In this embodiment, there are two air intakes 31, but the number is arbitrary. The air intake 31 is provided on the back side of the sole portion 3, that is, on the heel side. With this configuration, compared to a configuration in which the air intake 31 is provided on the toe side, dirt such as mud is less likely to get in when walking, and the air intake function can be maintained. In addition, in sneakers, the sole portion 3 on the toe side is usually configured to be thin in order to exert its function. In this regard, according to the configuration of the present application, since the air intake 31 is provided on the heel side, the functionality of the sneaker can be maintained even when the footwear 1 is configured in a sneaker shape. Note that, when the footwear 1 is configured as a type of shoe having a thickness on the toe side of the sole portion 3, such as a leather shoe, the air intake 31 may be provided on the toe.

[0017] The air chamber 32 is a space having a predetermined volume, and communicates with the outside via the air intake 31. A check valve 40 may be disposed between the air intake 31 and the air chamber 32. When the sole portion 3 touches the ground as a result of walking, the air chamber 32 is compressed by the pressure generated in the sole portion 3. In response to the compression, the air in the air chamber 32 flows into the carbon dioxide absorption portion 33. Also, when the footwear 1 leaves the ground as a result of walking, the air chamber 32 recovers to almost its original volume as the sole portion 3 returns to its original position. In other words, the air chamber 32 repeatedly compresses and recovers as the wearer walks, and serves as a pump that sends air to the carbon dioxide absorption portion 33.

[0018] The carbon dioxide absorbing section 33 is a space that communicates with the air chamber 32. The rear end (heel side) of the carbon dioxide absorbing section 33 communicates with the air chamber 32. In addition, the front end (toe side) of the carbon dioxide absorbing section 33 communicates with the exhaust port 34. That is, air introduced from the intake port 31 passes through the air chamber 32 and the carbon dioxide absorbing section 33 in this order, and is discharged from the exhaust port 34.

[0019] 4, the carbon dioxide absorbing section 33 includes a carbon dioxide separation membrane 331 and a carbon dioxide absorbent 332. The carbon dioxide separation membrane 331 and the carbon dioxide absorbent 332 are each formed across the left and right direction of the carbon dioxide absorbing section 33, and both ends are connected to the left and right inner walls. That is, the air flowing in from the air chamber 32 always passes through the carbon dioxide separation membrane 331 and the carbon dioxide absorbent 332.

[0020] The carbon dioxide separation membrane 331 is a membrane that selectively allows carbon dioxide to permeate. Air that flows in from the right side of the figure is pressed against the carbon dioxide separation membrane 331 by the pressure generated in the sole portion 3 by walking, so that carbon dioxide is separated and the air passes to the left of the carbon dioxide separation membrane 331.

[0021] The carbon dioxide absorbent 332 is made of an appropriate material that absorbs carbon dioxide. The carbon dioxide absorbent 332 absorbs carbon dioxide that has permeated the carbon dioxide separation membrane 331. The carbon dioxide absorbent 332 may be configured to change color depending on the amount of carbon dioxide absorbed. In this case, the color of the carbon dioxide absorbent 332 may be made visible through an appropriate window provided in the sole portion 3. With this configuration, the carbon dioxide absorption function of the footwear 1 can be checked at any time. In addition, the carbon dioxide absorbent 332 may be replaceable by being removed through the window or another appropriate window.

[0022] The gas that has not been absorbed is discharged from an exhaust port 34 that communicates with the carbon dioxide absorption section 33 . The exhaust port 34 is disposed in front of the footwear, i.e., on the toe side, relative to the intake port 31. When walking, the heel usually touches the ground first, and the center of gravity of the body weight gradually moves forward. Therefore, the air and carbon dioxide are sequentially pressurized from the intake port 31 toward the exhaust port 34 by the weight shift of walking. In other words, according to this configuration, the gas can be guided from the intake port 31 to the exhaust port 34 by utilizing the weight shift of walking.

[0023] In addition, the exhaust port 34 is provided on the inner thigh side (arch side) of the exterior of the footwear when it is worn. That is, the exhaust ports 34 of the pair of left and right footwear face each other. With this configuration, the exhaust port 34 can be kept open without being affected by dirt or mud splashes during walking. Also, as shown in FIG. 2, a plurality of exhaust ports 34 may be provided. Note that a valve 41 may be provided at the boundary between the exhaust port 34 and the carbon dioxide absorption section 33. With this configuration, it is possible to prevent dirt that has entered through the exhaust port 34 from reaching the carbon dioxide absorption section 33. This valve 41 may be a check valve that allows gas to flow only in the direction from the carbon dioxide absorption section 33 to the exhaust port 34.

[0024] According to the footwear according to the present embodiment described above, it is possible to contribute to the reduction of carbon dioxide with a simple configuration by utilizing the force of the wearer's walking, etc.

[0025] Carbon dioxide absorption device (1) 5 shows an example of a carbon dioxide absorbing device 100 that absorbs carbon dioxide by utilizing the exercise of pedaling a bicycle ergometer 110. The bicycle ergometer 110 is equipped with pedals 120, and the carbon dioxide absorbing device 100 is designed to operate in response to the rotation of the pedals 120.

[0026] The carbon dioxide absorbing device 100 is mainly composed of a drive unit 121 of a bicycle ergometer 110, a blower 122, and a carbon dioxide absorbing unit 123. The drive unit 121 is a member that transmits the rotation of the shaft of the pedal 120 to the blower 122. The blower 122 is a device that blows air to the carbon dioxide absorbing unit 123 by the force transmitted from the drive unit 121. The carbon dioxide absorbing unit 123 has a configuration similar to that of the carbon dioxide absorbing unit 33 (see FIG. 4) in the footwear 1, and the air blown from the blower 122 flows into the carbon dioxide absorbing unit 123 and is absorbed by the carbon dioxide absorbent material therein. Even with this configuration, it is possible to reduce carbon dioxide using human power without emitting further carbon dioxide through electricity consumption or the like.

[0027] Carbon dioxide absorption device (2) 6 shows an example of a carbon dioxide absorbing device 200 that absorbs carbon dioxide by utilizing the stepping motion of a foot-stepping exercise device 210, commonly known as a stepper. The foot-stepping exercise device 210 is equipped with a pedal 220, and the carbon dioxide absorbing device 200 is designed to operate in response to the up and down motion of the pedal 220.

[0028] The carbon dioxide absorbing device 200 is mainly composed of a bellows 222 attached below the pedal 220 of the foot-operated exercise device 210, and a carbon dioxide absorbing section 223. When the pedal 220 is lowered, the moving section of the bellows 222 comes into contact with the back surface of the pedal 220 and is pressed. The carbon dioxide absorbing section 223 has a similar configuration to the carbon dioxide absorbing section 33 (see FIG. 4) in the footwear 1, and the air blown from the bellows 222 flows into the carbon dioxide absorbing section 223 and is absorbed by the carbon dioxide absorbing material therein. With this configuration as well, it is possible to reduce carbon dioxide using human power without emitting further carbon dioxide through electricity consumption, etc.

[0029] Although the present invention has been described above using the embodiments, the technical scope of the present invention is not limited to the scope described in the above embodiments, and various modifications and changes are possible within the scope of the gist of the present invention. For example, although the present description has been given using an example of a configuration for absorbing carbon dioxide, a configuration for absorbing a greenhouse gas other than carbon dioxide may also be used.
