Description

[Technical field]

[0001] The present invention particularly relates to an exercise device that utilizes the power of the user to absorb carbon dioxide. [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]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0013] ●Exercise equipment (1) Hereinafter, an exercise device according to an embodiment of the present invention will be described with reference to the drawings. The exercise device according to the present invention absorbs carbon dioxide by utilizing the force generated in response to the movement of the user when the user uses the exercise device.

[0014] For example, as shown in FIG. 1, an exercise device 1 mainly includes a change section 2, an action section 3, an intake port 4, an air chamber 5, a communication passage 6, a carbon dioxide absorption section 7, an exhaust port 8, and the like.

[0015] The changeable portion 2 is a member that changes according to the user's action. In this embodiment, the changeable portion 2 includes at least a weight 20 that the user P lifts. One end of a cable 21 is connected to the upper end of the weight 20. The cable 21 is bent from upward to downward via a plurality of pulleys 23 held by a support 22, and a gripping portion 24 that the user P can grip is connected to the other end of the cable 21. As a result, when the user P pulls the gripping portion 24 diagonally downward, the force is transmitted to the weight 20 via the cable 21, and the weight 20 is lifted. The weight 20 is inserted into a plurality of appropriate poles 25 that extend in the vertical direction, and moves up and down along the poles 25. In addition, since the weight 20 is biased downward by gravity, when the user P slowly releases the force, it moves downward accordingly. That is, in this embodiment, the change in the changeable portion 2 refers to at least the vertical movement of the position of the weight 20. By using such an exercise machine 1, the user P can perform muscle training by applying the load of the weight 20 to the muscles of the back and the like by pulling down the grip portion 24 and relaxing the grip portion 24.

[0016] The exercise device 1 in this embodiment is a so-called lat pull machine in which the grip part 24 is suspended diagonally above the head of the user P and pulled down to train the muscles. However, the technical scope of the present invention is not limited to this, and may be an exercise device in which the grip part 24 is pulled in an appropriate posture to train any muscle. In addition, in this embodiment, the weight 20 is biased by gravity, and the user performs muscle training by moving the weight 20 against gravity, but the force biasing the weight 20 is not limited to gravity, and may be an appropriate force such as the elastic force of a spring. Furthermore, the exercise device included in the technical scope of the present invention may be an exercise device equipped with an appropriate member that changes according to the user's movement, in addition to the examples shown individually. For example, it may be a so-called leg press in which the user steps on an appropriate change part to move it. In addition, it may be a device in which the weight rotates in the roll direction, pitch direction, yaw direction, etc. according to the movement of the user P.

[0017] The changeable portion 2 also includes a contact portion 26 that extends below the weight 20. The contact portion 26 is, for example, a rod-shaped member, and is adapted to contact the action portion 3 at its lower end. The contact portion 26 contacts the action portion 3 at least when the weight 20 is in a predetermined range below, and pushes the action portion 3 downward as the weight 20 moves downward. The contact portion 26 may be spaced apart from the action portion 3 when the weight 20 is relatively above. In this case, it is preferable to provide an appropriate biasing member that restores the action portion 3 to its original position at least when the weight 20 is separated. Note that the embodiments of the exercise device shown below may also include an appropriate biasing member. The contact portion 26 may also be connected to the action portion 3.

[0018] In this embodiment, the contact portion 26 is a straight rod, and the action portion 3 is disposed below the weight 20, but the contact portion 26 may be configured to be bent. In this case, the action portion 3 can be disposed at any position away from directly below the weight 20 depending on the shape of the contact portion 26.

[0019] The action part 3 is a member that advances and retreats in response to the change of the change part 2. The action part 3 is, for example, a plate-shaped member, and is housed in the air chamber 5. The action part 3 has a shape that corresponds to a surface of the air chamber 5 that is perpendicular to the moving direction of the action part 3, for example, and the end of the action part 3 slides along the side of the air chamber 5. The action part 3 also compresses the air in the air chamber 5 by advancing and retreating up and down. In this embodiment, the action part 3 has a shape that corresponds to the lower surface of the air chamber 5. Note that, although the action part 3 is flat in the figure, the end may be bent downward.

[0020] The air intake 4 is disposed in the air chamber 5 and is a hole that communicates between the inside of the air chamber 5 and the outside. The air intake 4 allows air to flow into the air chamber 5 as the working part 3 rises. The air intake 4 may be provided with a check valve.

[0021] The communication passage 6 is a pipe that communicates between the air chamber 5 and the carbon dioxide absorbing section 7. The air in the air chamber 5 compressed by the action section 3 flows into the carbon dioxide absorbing section 7 through the communication passage 6.

[0022] The carbon dioxide absorbing section 7 is a space having a predetermined volume, and communicates with the air chamber 5 via the communication passage 6. Between the communication passage 6 and the carbon dioxide absorbing section 7, a check valve may be disposed.

[0023] 2, the carbon dioxide absorbing section 7 includes a carbon dioxide separation membrane 71 and a carbon dioxide absorbent 72. The carbon dioxide separation membrane 71 and the carbon dioxide absorbent 72 are each formed across the left and right direction of the carbon dioxide absorbing section 7, and both ends are connected to the left and right inner walls. That is, the air that flows in from the air chamber 5 always passes through the carbon dioxide separation membrane 71 and the carbon dioxide absorbent 72.

[0024] The carbon dioxide separation membrane 71 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 71 by the pressure generated by the action unit 3, whereby carbon dioxide is separated and the air passes to the left of the carbon dioxide separation membrane 71.

[0025] The carbon dioxide absorbent 72 is made of an appropriate material that absorbs carbon dioxide. The carbon dioxide absorbent 72 absorbs carbon dioxide that has permeated the carbon dioxide separation membrane 71. The carbon dioxide absorbent 72 may be configured to change color depending on the amount of carbon dioxide absorbed. In this case, the color of the carbon dioxide absorbent 72 may be made visible through an appropriate window provided in the carbon dioxide absorbing unit 7. With this configuration, the carbon dioxide absorption function of the exercise apparatus 1 can be checked at any time. The carbon dioxide absorbent 72 may be replaceable by being removed through the window or another appropriate window. The carbon dioxide absorbing unit 7 may be detachably connected to the communication passage 6, making the carbon dioxide absorbing unit 7 itself replaceable.

[0026] The gas that has not been absorbed is discharged from an exhaust port 8 that communicates with the carbon dioxide absorbing unit 7. A check valve that allows gas to flow only in the direction from the carbon dioxide absorbing unit 7 to the exhaust port 8 may be provided at the boundary between the exhaust port 8 and the carbon dioxide absorbing unit 7.

[0027] When the user P pulls on the gripping part 24, air flows into the air chamber 5 via the air intake 4. When the user P stops actively pulling on the gripping part 24, the weight 20 descends due to gravity, causing the action part 3 to descend and compress the air inside the air chamber 5. In response to the compression, the air inside the air chamber 5 flows into the carbon dioxide absorption part 7. In other words, the air chamber 5 repeats compression and recovery in response to the muscle training of the user P, and serves as a pump that sends air to the carbon dioxide absorption part 7.

[0028] The exercise device according to the present invention described above can contribute to the reduction of carbon dioxide emissions with a simple configuration by utilizing the force generated in response to the user's movements. In particular, the movements generated during strength training can be utilized to reduce carbon dioxide emissions. With such an exercise device, the user can feel the extent of their contribution because their own movements directly lead to the reduction of carbon dioxide emissions.

[0029] ●Exercise equipment (2) Exercise device 101 shown in Fig. 3 is a second embodiment of the exercise device according to the present invention. This exercise device 101 is a so-called rowing machine, in which the seat on which the user sits slides back and forth together with the user's body as the user bends and stretches. In the following description, the same components as those in the previously described exercise device 1 are given the same reference numerals and will not be described. As shown in Fig. 1, exercise device 101 mainly includes a change section 120, an action section 130, an intake port 4, an air chamber 150, a communication passage 6, a carbon dioxide absorption section 7, and an exhaust port 8.

[0030] The changeable unit 120 includes a seat 121 on which the user P sits. The seat 121 is held by rails 122 that extend in a direction along the lower limbs of the user P when the user P is sitting on the seat 121. The seat 121 is connected to the rails 122 so as to be slidable back and forth along the rails 122.

[0031] Exercise device 101 also includes fixed base 123 placed on the floor surface, and gripping portion 124 connected to fixed base 123 by an appropriate cable or the like. Fixed base 123 is provided with an appropriate foot receiving portion against which user P places the sole of the foot. By bending and straightening the feet, user P receives a reaction force from the foot receiving portion and moves back and forth together with seat 121 along rail 122.

[0032] A first end of the contact portion 126 is connected to the seat 121. The contact portion 126 is a rod-shaped member extending rearward from the seat 121. A second end of the contact portion 126 is connected to the action portion 130 housed in the air chamber 150. As a result, when the seat 121 moves forward and backward in accordance with the movement of the user P, the action portion 130 moves forward and backward inside the air chamber 150. As a result, the action portion 130 compresses the air inside the air chamber 150 and causes the air to flow into the carbon dioxide absorption portion 7 through the communication passage 6. In this embodiment, the action portion 130 is a thin plate having a shape corresponding to the side surface of the air chamber 150, and moves forward and backward in accordance with the movement of the seat 121. The contact portion 126 may be bent in the same manner as the contact portion 26 described above. In addition, the action direction of the contact portion 126 may be converted to a vertical direction by an appropriate gear structure, and the action portion 130 may move up and down inside the air chamber 150. Such an exercise device 101 can also utilize the force generated during the exercise movement of the user to reduce carbon dioxide in the air.

[0033] ●Exercise equipment (3) 4 shows a bicycle ergometer, which is an example of an exercise device 201 that absorbs carbon dioxide by utilizing pedaling motion. Exercise device 201 is equipped with pedals 220 that rotate with the motion of the user, and air is blown to carbon dioxide absorbing section 7 in response to the rotation of pedals 220. Pedals 220 are another example of the "changing section" in the claims.

[0034] The exercise device 201 is mainly composed of an action unit 230, a blower 240, and a carbon dioxide absorption unit 7. The action unit 230 is a member that transmits the rotation of the shaft of the pedal 220 to the blower 240. The blower 240 is a device that rotates its blades by the force transmitted from the action unit 230 and blows air to the carbon dioxide absorption unit 7, and is another example of the "action unit" in the claims. The carbon dioxide absorption unit 7 has a configuration similar to that of the carbon dioxide absorption unit 7 (see FIG. 2) in the exercise device 1, and the air blown from the blower 240 flows into the carbon dioxide absorption unit 7 through the communication passage 6 and is absorbed by the carbon dioxide absorption material 72 (see FIG. 2) inside. Even with this configuration, carbon dioxide can be reduced by using human power without emitting further carbon dioxide through electricity consumption or the like.

[0035] ●Exercise equipment (4) FIG. 5 shows a treadmill, which is an example of an exercise device 301 that absorbs carbon dioxide by utilizing the force of a user walking or running on an endless belt 310. The exercise device 301 includes an endless belt 310, a roller 330, a blower 240, a communication passage 6, and a carbon dioxide absorbing section 7. The endless belt 310 is held by the roller 330 that rotates with the rotation of the endless belt 310. The endless belt 310 and the roller 330 rotate in response to the user's movement on the endless belt 310, particularly walking or running. The type of movement is arbitrary as long as the movement causes the endless belt 310 to rotate. The endless belt 310 and the roller 330 are another example of a "changing section" in the claims.

[0036] According to the above-mentioned configuration, the roller 330 rotates as the user moves on the endless belt 310, and the wind generated by the blower 240 in response to this rotation is sent to the carbon dioxide absorbing section 7 through the communication passage 6. That is, carbon dioxide can be reduced by using the human power of the user.

[0037] ●Exercise equipment (5) The exercise device 401 shown in FIG. 6 is a fourth embodiment of the exercise device according to the present invention, and is another example of the configuration of a treadmill. The exercise device 401 mainly includes an endless belt 310, an air chamber 350, a communication passage 6, and a carbon dioxide absorbing section 7. The carbon dioxide absorbing section 7 has the same configuration as the carbon dioxide absorbing section 7 in the exercise device 1 (see FIG. 2). The air chamber 350 is disposed directly under the endless belt 310, and is compressed as the user steps on the endless belt 310. In addition, at least a part of the air chamber 350 is made of an elastic material such as an elastic body, and is designed to return to its original shape when the load from the user is removed. In the figure, the air chamber 350 is formed with a thickness from the floor surface to directly under the endless belt 310, but it may be formed thinly in a sheet shape along the endless belt 310. The air chamber 350 is connected to the carbon dioxide absorbing section 7 via the communication passage 6. According to this configuration, when the user walks, runs, or performs other actions on the endless belt 310, the air chamber 350 is compressed, and the air inside the air chamber 350 is guided to the carbon dioxide absorbing section 7 via the communication passage 6. Therefore, it is possible to reduce carbon dioxide using human power according to the user's actions.

[0038] ●Exercise equipment (6) 7 shows an example of exercise device 501 that absorbs carbon dioxide by utilizing the stepping motion of a foot-stepping exercise device known as a stepper. Exercise device 501 is equipped with pedal 520, and exercise device 501 is operated in response to the up and down motion of pedal 520. Pedal 520 is another example of the "changing portion" in the claims.

[0039] The exercise device 501 is mainly composed of a bellows 522 attached below the pedal 520 of the exercise device 501 and a carbon dioxide absorbing unit 7. The bellows 522 is a general term for an apparatus that sends out air by changing the volume of an airtight space, and various types of fine structures can be adopted as long as the air is compressed by pushing the action part 530 and the air is blown. The action part 530 of the bellows 522 has a shape corresponding to the bottom surface of the air chamber 550, and when the action part 530 descends, the air in the air chamber 550 is compressed. In addition, a protrusion extending upward is formed on the top surface of the action part 530, and this protrusion is adapted to come into contact with the descending pedal 520. That is, the action part 530 of the bellows 522 comes into contact with and is pressed against the back surface of the pedal 520 as the pedal 520 descends. The carbon dioxide absorbing section 7 has a similar configuration to the carbon dioxide absorbing section 7 (see FIG. 2) in the exercise device 1, and the air blown from the air chamber 550 of the bellows 522 flows into the carbon dioxide absorbing section 7 and is absorbed by the carbon dioxide absorbing material 72 (see FIG. 2) therein. Even with this configuration, it is possible to reduce carbon dioxide by using human power without emitting further carbon dioxide through electricity consumption or the like.

[0040] ●Movement device (1) 8 shows an example of a moving device according to the present invention, which is a moving device 601 that absorbs carbon dioxide by causing air that flows from the front to the rear as the device moves to flow into a carbon dioxide absorbing unit 607. The moving device 601 may be any suitable device that is moved by human power, and is a bicycle in this embodiment. The moving device 601 has one or more carbon dioxide absorbing units 7. In the figure, the carbon dioxide absorbing units 607 are disposed on the upper part of the handle of the moving device 601 and on the cover above the rear wheel, that is, on the so-called fender, but this is merely one example.

[0041] 9, the carbon dioxide absorbing unit 607 is, for example, a flat member having a rectangular shape in a top view, and has an intake port 73 through which air flows in, and an exhaust port 74 through which air flows out after permeating the carbon dioxide absorbent 72. The air that flows in from the intake port 73 passes through the carbon dioxide separation membrane 71 and the carbon dioxide absorbent 72 in this order, and is discharged from the exhaust port 74.

[0042] As shown in FIG. 8, the intake port 73 of the carbon dioxide absorbing unit 7 is disposed so as to face the traveling direction of the moving device 601. With this configuration, air flowing from the front to the rear as the moving device 601 moves is efficiently guided to the intake port 73. The intake port 73, the carbon dioxide separation membrane 71, the carbon dioxide absorbent 72, and the exhaust port 74 are formed in this order on a substantially straight line. That is, the carbon dioxide absorbent 72 is disposed so as to be perpendicular to the traveling direction. The exhaust port 74 faces rearward in the traveling direction of the moving device 601. With this configuration, air can be pressed against the carbon dioxide absorbent 72 by utilizing the wind force generated in the moving device 601 by the movement. As a result, carbon dioxide can be absorbed more efficiently.

[0043] ●Clothing (1) FIG. 10 shows an example of a garment according to the present invention, which is a hat 701 that absorbs carbon dioxide by allowing air that flows from the front to the rear as the user moves to flow into the carbon dioxide absorbing section 607. The carbon dioxide absorbing section 607 disposed in the hat 701 may have a configuration equivalent to that shown in FIG. 9. The carbon dioxide absorbing section 607 in FIG. 10 may be curved along the shape of the hat. The air inlet 73 of the carbon dioxide absorbing section 607 is disposed so as to face the front of the hat 701. The front of the hat 701 faces the front of the user wearing the hat 701, and faces the direction of travel. The exhaust port (not shown) is formed on the back side of the hat 701. When the user moves forward, wind is generated in the hat 701 that flows from the front to the rear. Therefore, the hat 701 can absorb carbon dioxide as the user moves forward. With this configuration, the user can absorb carbon dioxide simply by walking or running while wearing the hat 701. In other words, it is possible to easily contribute to reducing carbon dioxide emissions using human power.

[0044] ●Clothing (2) FIG. 11 shows another example of clothing according to the present invention, which is clothing 801 that absorbs carbon dioxide by making air that flows from the front to the rear as the user moves flow into carbon dioxide absorbing section 607. This carbon dioxide absorbing section 607 is disposed so that air intake 73 faces the front side of the shoulder of clothing 801. An exhaust port (not shown) is formed on the rear side of clothing 801. With this configuration, air intake 73 faces in the direction of travel, so that carbon dioxide can be absorbed as the user moves. As a result, the user can easily contribute to reducing carbon dioxide emissions using human power. Such hat 701 and clothes 801 are more effective when configured as sportswear that involves vigorous movement. Although clothes 801 are described as being worn on the upper body, they may be worn on the lower body. Further, in the present description, an example has been given in which the carbon dioxide absorbing section is provided in a hat and clothing, but the technical concept of the present invention is not limited to this and can be applied to any clothing or accessory worn by a person.

[0045] 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.
