Description

Shoe removable grounding device

[0001] The present invention relates to a shoe detachable grounding device, and more particularly, to a shoe detachable grounding device in which a substrate is fastened to the sole and upper of the shoe, a tip in contact with the ground is joined to the substrate through an elastic portion, and a band in contact with the foot and the substrate are detachable, so that when the shoe is taken off, the band falls off from the substrate, making it convenient to wear, and the substrate can be directly fixed to various types of shoes by the user.

[0002] Walking barefoot is commonly referred to as "earthing" or "grounding." This concept is based on the theory that the human body can gain health benefits by absorbing the Earth's electrical charge through direct contact with it. Static electricity, or excess electrical charge accumulated in the body, is said to flow to the ground, theoretically rebalancing the body's electrical balance, reducing inflammation, and improving health.

[0003] The concept of "earthing" or "earthing" was first proposed by Clinton Ober. He details the theory in his book, "Earthing: The Most Important Health Discovery Ever?", which is based on the idea that contact with nature can improve health.

[0004] Research suggests that endurance exercise can improve sleep quality, reduce pain, alleviate stress, and promote heart health. It also suggests that it can help reduce static electricity in the body and regulate the body's physiological rhythms.

[0005] Previously, technologies have been proposed to allow the foot to come into contact with the ground by connecting the shoe insole and the ground as a grounding part or by making contact between a lower conductor penetrating the insole and an upper conductor provided in the insole.

[0006] However, the conventional method was limited to specific shoes and had limitations in applying it to various shoes because it was a configuration that consumers could not assemble themselves.

[0008] Document 1: Patent Publication No. 10-2335608

[0009] Document 2: Patent Registration No. 10-2652205

[0010] The present invention has been developed in consideration of the problems of the prior art, and the purpose of the present invention is to provide a shoe detachable grounding device in which a substrate is fastened to the sole and upper of a shoe, a tip in contact with the ground is fastened to the substrate through an elastic portion, and a band in contact with the foot and the substrate are detached by a magnet, so that when the shoe is taken off, the band falls off the substrate, making it convenient to wear, and the user can directly fasten the substrate to the sole of the shoe, thereby providing a shoe detachable grounding device that can be fixed to various types of shoes.

[0011] In order to achieve the above object, a shoe detachable grounding device of one embodiment of the present invention comprises a conductive substrate that is connected to the sole and upper of the shoe and exposed to the outside of the shoe, a conductive band that comes into contact with the foot and is detachable from the substrate, and a conductive elastic portion that allows a conductive tip that comes into contact with the ground to be elastically connected to the substrate, and the substrate and the band are configured to be detachable in the form of either a magnet or a button.

[0012] The above substrate is configured to include a fitting portion that is open toward the upper portion to allow a magnet to be fitted, and the lower portion of the band may be provided with a detachable portion that is magnetically attached to the outer surface of the fitting portion.

[0013] The above substrate is configured to include a fitting portion that is open toward the upper surface to allow a magnet to be fitted, and a band magnet attached to the outer surface of the fitting portion may be built into the inner side of the lower portion of the band.

[0014] The above substrate may have a protrusion formed on the outside, and the band may be provided with a button portion in the form of a snap button that detachably attaches to the protrusion.

[0032] Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the attached drawings.

[0033] FIG. 1 is a perspective view showing the disassembly and assembly of the first embodiment of the present invention, and FIG. 2 (a) and (b) are cross-sectional views showing the detachable structure of the band and the substrate in the first embodiment of the present invention. The shoe detachable grounding device of the first embodiment of the present invention is configured to include a substrate (100) made of a conductive material and fastened to the sole (500) and the upper (501) of the shoe, a conductive flexible band (200) detachably attached to the substrate (100) and in contact with the ankle, and a conductive elastic portion (300) that allows a conductive tip (400) in contact with the ground to be elastically coupled to the substrate (100).

[0034] The above substrate (100) has a sole fixing hole (101) formed at the bottom to guide a screw-shaped sole fixing member (100a) to be fixed to a shoe sole (500) placed where both feet meet, and an upper fixing hole (102) formed at the top to guide an upper fixing member (100b) to be fixed to the shoe upper (501).

[0035] The above upper fixing member (100b) is composed of a head portion (100c) and a hollow pin, and a fixing pin (100d) is inserted into the pin and pressed to fix the upper portion (501) and the substrate (100), and the head portion (100c) can come into contact with the foot inside the shoe.

[0036] The above upper fixing member (100b) may be used to fix the substrate (100) and the upper (501) by drilling a hole in the upper (501) and then riveting it.

[0037] The above substrate (100) is configured to include a fitting part (103) on the outer side that does not touch the upper part (501), and a hollow magnet (105) is fitted on the inner side of the fitting part (103) that is open toward the upper part (501), and a detachable groove (104) is formed on the outer side.

[0038] The above band (200) is configured to include a detachable part (201) made of metal that is attached to the outer surface of the fitting part (103) via the magnet (105).

[0039] The above detachable portion (201) has a protrusion (202) formed on one side to be fitted into a detachable groove (104) formed in the fitting portion (103), and a fastening hole (203) is perforated at the top to fit and hang the band (200).

[0040] The above elastic part (300) is configured in the form of a coil spring, and the substrate (100) is configured to include a guide part (106) into which the elastic part (300) is fitted, and an adjustment part (107) that can adjust the fitted height of the elastic part (300).

[0041] The above-mentioned tip portion (400) is configured to include a conductive cylindrical connecting portion (401) that is detachably fitted to the lower portion of the elastic portion (300), and the upper portion of the elastic portion (300) is provided with a handle that can be rotated.

[0042] The upper part of the above band (200) can be folded into both feet and have a built-in core (204) so ​​that it remains in direct contact with the ankle.

[0043] The lower part of the above substrate (100) may be configured to include a grounding portion (110) that is placed on the bottom surface of the sole (500) and directly touches the ground together with the sole (500).

[0044] The first embodiment of the present invention configured in this manner operates as follows.

[0045] First, a sole fixing member (100a) is inserted into the sole fixing hole (101) of the lower part of the substrate (100) to fix it to the shoe sole (500), and a hole is drilled into the shoe upper (501) corresponding to the upper fixing hole (102) of the upper, using an awl or the like, into which a pin of the upper fixing member (100b) can be inserted.

[0046] Next, by inserting the pin of the upper fixing member (100b) into the upper (501) and the sole fastening hole (101) so that the head (100c) is positioned inside the shoe, and then inserting the fixing pin (100d) into the hollow pin and pressing it, the upper fixing member (100b) is fixed so that the substrate (100) can be vertically fixed to the sole (500) and the upper (501) formed on the inner facing surfaces of both shoes, and thus can be applied to various types of shoes.

[0047] Continuing, the tip (400) is connected to the lower end of the elastic part (300) through the connecting part (401), and the elastic part (300) is fitted into the guide part (106) and then partially caught on the horizontally placed adjusting part (107), so that the lower end of the tip (400) can elastically contact the ground.

[0048] In addition, the band (200) can be folded so that the upper part is folded inside the sock to make direct contact with the ankle, and if a core (204) is built in, folding it can prevent the folded state of the band (200) from coming loose.

[0049] As shown in Fig. 2(a), when the detachable portion (201) at the bottom of the band (200) comes into contact with the fitting portion (103), they do not fall off easily due to the magnet (105), and in particular, since the protrusion (202) enters the detachable groove (104), the bonding strength can be increased.

[0050] As in Fig. 2(b), even if the detachable portion (201) comes into contact with the fitting portion (103) so that the protrusion (202) does not enter the detachable groove (104), the contact force between them can be maintained through the magnet (105).

[0051] Continuing, when wearing shoes with a combined substrate (100) and walking, the tip (400) elastically touches the ground, so that static electricity accumulated on the body can flow to the ground through the band (200), detachable portion (201), fitting portion (103), substrate (100), elastic portion (300), and tip (400).

[0052] Next, since the substrate (100) is electrically connected to the ground through the grounding portion (110) that directly touches the ground at the bottom of the sole (500), the grounding force that is lacking at the tip (400) can be added at the grounding portion (110).

[0053] Meanwhile, when the tip (400) gets stuck in a gap between sidewalk blocks, an escalator groove, or a small gap while walking, the elastic part (300) separates from the connecting part (401), so that walking is not hindered.

[0054] And, in the process of taking off the shoes, the band (200) that has entered the sock is pulled, and the detachable part (201) falls off from the magnetic force of the magnet (105) built into the fitting part (103), so there is no need to bend down and separate the band (200) from the substrate (100).

[0055] Continuing, in the process of wearing the shoe, the detachable part (201) hanging from the band (200) is attached to the fitting part (103) due to the magnetic force of the magnet (105), thereby electrically connecting the band (200) and the substrate (100).

[0056] FIG. 3 is a cross-sectional view showing another detachable structure of a band and a substrate in the first embodiment of the present invention, which has the same configuration as one form of the first embodiment except that a hollow band magnet (205) is embedded in the lower part of the band (200) without using a detachable portion (201).

[0057] Accordingly, when the shoes are worn, the band magnet (205) sticks to the magnet (105), so that the band (200) and the fitting part (103) come into direct contact and conduct electricity, and when the shoes are taken off, the band (200) with the upper part fitted into the sock is pulled, so that the band magnet (205) can be separated from the magnet (105).

[0058] FIG. 4 is a cross-sectional view showing another detachable structure of a band and a substrate among the first embodiment of the present invention, in which a conductive protrusion (108) is protruded and fixed to the substrate (100) by a riveting method, and a conductive button (206) that is connected to the protrusion (108) by a snap button method is fastened to the lower end of the band (200) by a riveting method.

[0059] Accordingly, when the shoes are put on and the button portion (206) is pressed against the protrusion (108) to fasten the button, the band (200) and the substrate (100) can be electrically connected, and conversely, when the button portion (206) is pulled to detach it from the protrusion (108), the shoes can be taken off.

[0060] FIG. 5 is a perspective view showing another form of an elastic part in the first embodiment of the present invention, in which the elastic part (300) has a structure in which a steel wire is bent in a zigzag shape on a plane, and a connecting part (401) is formed as a square groove into which the lower end of the elastic part (300) is detachably fitted, and a tip part (400) is coupled to the lower end of the connecting part (401).

[0061] The above substrate (100) is provided with a guide portion (106) into which the elastic portion (300) on the above plane is fitted, and a multi-stage adjustment portion (107) is provided on the upper portion so that the elastic portion (300) bent in a zigzag pattern is fitted in multiple stages to adjust the height.

[0062] Among the first embodiment of the present invention configured in this way, another form of the elastic part has the advantage of not protruding much from the substrate (100) compared to a configuration in which the elastic part (300) is formed on a plane.

[0063] Continuing, since the elastic part (300) is caught in multiple stages in a zigzag shape on the control part (107), when the tip part (400) wears out and does not touch the ground, the caught area can be adjusted in stages, and when the tip part (400) is stuck in the ground and cannot come out, the connecting part (401) is peeled off from the elastic part (300), so that a safety accident can be prevented.

[0064] FIG. 6 is a perspective view showing another form of an elastic part among the first embodiment of the present invention, in which the conductive elastic part (300) is made of an elastic plate material and has a plurality of adjustment holes (301).

[0065] A conductive tip (400) having elasticity is fitted into a groove formed at the bottom of the elastic part (300) and assembled, and a control pin (109) into which the control hole (301) is fitted and a guide part (106) into which the elastic part (300) is fitted are formed on the substrate (100).

[0066] Another form of the elastic part among the first embodiment of the present invention configured in this way is that the multi-stage adjustment holes (301) formed in the elastic part (300) are gradually fitted into the adjustment pin (109) of the substrate (100), so that when poor contact with the ground occurs due to wear of the tip (400), it can be resolved.

[0067] FIG. 7 is a perspective view showing another form of an elastic part among the first embodiment of the present invention, in which a conductive elastic part (300) is made of an elastic steel material and includes a bent part (402) bent in a “ㄷ” shape on a plane, and a tip part (400) is integrally provided at the lower part.

[0068] The above substrate (100) is provided with a guide part (106) that guides the bending part (402) to move elastically by being fitted horizontally, and a pair of adjusting parts (107) that hold the upper part of the elastic part (300) are provided vertically close to the upper part.

[0069] Another form of the elastic part among the first embodiment of the present invention configured in this way is to fit a bending part (402) formed in the middle of the elastic part (300) into a guide part (106) formed on a substrate (100) and place the upper part on a pair of adjusting parts (107), so that the lower tip part (400) can elastically contact the ground through the bending part (402).

[0070] Next, if the tip (400) is stuck in the ground and cannot come out, the bending part (402) comes off from the guide part (106), so that the elastic part (300) is separated from the substrate (100), thereby preventing a safety accident.

[0071] FIG. 8 is a perspective view showing a disassembled and assembled state of a second embodiment of the present invention, and FIG. 9 is a cross-sectional view showing a fastening structure of a band and a substrate in the second embodiment of the present invention. The shoe detachable grounding device of the second embodiment of the present invention is configured to include a substrate (100) made of a conductive material and fastened to the sole (500) and the upper (501) of the shoe, a conductive flexible band (200) fastened to the substrate (100) through the upper (501) and in contact with the ankle, and a conductive elastic portion (300) that allows a conductive tip (400) in contact with the ground to be elastically coupled to the substrate (100).

[0072] The above substrate (100) has a sole fixing hole (101) formed at the bottom to guide a screw-shaped sole fixing member (100a) to be fixed to a shoe sole (500) placed where both feet meet, and an upper fixing hole (102) formed at the top to guide an upper fixing member (100b) to be fixed to the shoe upper (501).

[0073] The upper fixing member (100b) is composed of a head portion (100c) and a hollow pin, and the band (200), the upper portion (501), and the substrate (100) are fixed by the fixing pin being inserted into the pin and compressed, and the head portion (100c) can come into contact with the foot inside the shoe.

[0074] The above upper fixing member (100b) may be formed by drilling a hole in the band (200) and the upper (501) and then riveting the band (200), the upper (501) and the substrate (100) to be fixed thereto.

[0075] The above elastic part (300) is configured in the form of a coil spring, and the substrate (100) is configured to include a guide part (106) into which the elastic part (300) is fitted, and an adjustment part (107) that can adjust the fitted height of the elastic part (300).

[0076] The above-mentioned tip portion (400) is configured to include a conductive cylindrical connecting portion (401) that is detachably fitted to the lower portion of the elastic portion (300), and the upper portion of the elastic portion (300) is provided with a handle that can be rotated.

[0077] The lower part of the above band (200) is configured to wrap around the insole (502), and the upper part can be folded into both feet and have a built-in core material so that it remains in direct contact with the ankle.

[0078] The lower part of the above substrate (100) may be configured to include a grounding portion (110) that is placed on the bottom surface of the sole (500) and directly touches the ground together with the sole (500).

[0079] The second embodiment of the present invention configured in this manner operates as follows.

[0080] First, a sole fixing member (100a) configured in the form of a screw is inserted into the sole fixing hole (101) at the bottom of the substrate (100) to fix it to the shoe sole (500), and a hole is drilled using an awl or the like in the shoe upper (501) and band (200) corresponding to the upper fixing hole (102) at the top, into which a pin of the upper fixing member (100b) can be inserted.

[0081] Next, the head portion (100c) is caught on the band (200) and positioned inside the shoe, and the upper fixing member (100b) is inserted into the band (200), the upper (501), and the sole fixing hole (101), and then a fixing pin is inserted into the hollow pin and pressed to fix the substrate (100) vertically to the sole (500) and the upper (501) formed on the inner facing surfaces of both shoes, so that it can be applied to various types of shoes.

[0082] Continuing, the tip portion (400) is connected to the lower end of the elastic portion (300) through the connecting portion (401), and the elastic portion (300) is fitted into the guide portion (106) and then partially caught on the horizontally placed adjusting portion (107), so that the lower end of the tip portion (400) can be made to elastically contact the ground.

[0083] Additionally, the lower part of the band (200) can be wrapped around the upper and lower parts of the insole (502), and the upper part can be folded inside the sock to make direct contact with the ankle.

[0084] Next, when the shoe with the substrate (100) combined is worn and the tip (400) is elastically brought into contact with the ground, the static electricity accumulated in the body can flow to the ground through the band (200), the substrate (100), the elastic portion (300), and the tip (400).

[0085] Meanwhile, when the tip (400) gets stuck in a gap between sidewalk blocks, an escalator groove, or a small gap while walking, the elastic part (300) separates from the connecting part (401), so that walking is not hindered.

[0086] FIG. 10 is a cross-sectional view showing another fastening structure of a band and a substrate in the second embodiment of the present invention, in which the lower part of the band (200) is not rolled into the insole (502) but is partially placed above the insole (502), and the upper part is configured not to protrude outside the upper part (501).

[0087] In this way, the band (200) is not exposed to the outside of the upper (501), which is aesthetically pleasing, and when the shoes are worn barefoot without socks, the feet directly contact the band (200) and the head (100c) of the upper fastener (100b), so static electricity can be discharged to the ground.

[0088] FIG. 11 is a perspective view showing a disassembled and assembled state of a third embodiment of the present invention, and FIG. 12 is a cross-sectional view showing a third embodiment of the present invention. The shoe detachable grounding device of the third embodiment of the present invention comprises a substrate (100) made of a conductive material and fastened to the sole (500) and the upper (501) of the shoe, a conductive flexible band (200) fastened to the substrate (100) through the upper (501) and in contact with the ankle, and a conductive elastic portion (300) that allows a conductive tip (400) in contact with the ground to be elastically coupled to the substrate (100).

[0089] The above substrate (100) has a sole fastening hole (101) formed in a rectangular shape at the bottom to guide the sole fixing member (100a) to be fastened to the shoe sole (500) placed where both feet meet, and an upper fastening hole (102) formed in a rectangular shape at the top to guide the upper fastening member (100b) to be fastened to the shoe upper (501).

[0090] The above upper fixing member (100b) is composed of a head portion (100c) and a hollow pin, and fixes the band (200), the upper portion (501), and the substrate (100) by having the fixing pin inserted into the pin and pressed, and the head portion (100c) can come into contact with the foot inside the shoe.

[0091] The above upper fixing member (100b) may be formed by drilling a hole in the band (200) and the upper (501) and then riveting the band (200), the upper (501) and the substrate (100) to be fixed thereto.

[0092] The above elastic part (300) is configured to include a bent part (402) that is bent in a “ㄷ” shape on a plane, and the lower part is integrally provided with a tip part (400).

[0093] The above substrate (100) is provided with a guide part (106) that guides the bending part (402) to move elastically by being fitted horizontally, and a pair of adjusting parts (107) that hold the upper part of the elastic part (300) are provided vertically close to the upper part.

[0094] The lower part of the above band (200) is configured to wrap around the insole (502), and the upper part can be folded into both feet and have a built-in core material so that it remains in direct contact with the ankle.

[0095] The lower part of the above substrate (100) may be configured to include a grounding portion (110) that is placed on the bottom surface of the sole (500) and directly touches the ground together with the sole (500).

[0096] The third embodiment of the present invention configured in this manner operates as follows.

[0097] First, a sole fixing member (100a) is inserted into the sole fixing hole (101) of the lower part of the substrate (100) to fix it to the shoe sole (500), and a hole is drilled into the shoe upper (501) and band (200) corresponding to the upper fixing hole (102) of the upper using an awl or the like, into which a pin of the upper fixing member (100b) can be inserted.

[0098] Next, the head portion (100c) is caught on the band (200) and positioned inside the shoe, and the upper fixing member (100b) is inserted into the band (200), the upper (501), and the sole fixing hole (101), and then a fixing pin is inserted into the hollow pin and pressed to fix the substrate (100) vertically to the sole (500) and the upper (501) formed on the inner facing surfaces of both shoes, so that it can be applied to various types of shoes.

[0099] Continuing, by fitting the bending portion (402) formed in the middle of the elastic portion (300) into the guide portion (106) formed on the substrate (100) and placing the upper portion on a pair of adjusting portions (107), the lower tip portion (400) can be made to elastically contact the ground.

[0100] Next, if the tip (400) is stuck in the ground and cannot come out, the bending part (402) comes off from the guide part (106), so that the elastic part (300) is separated from the substrate (100), thereby preventing a safety accident.

[0101] Additionally, the lower part of the band (200) can be wrapped above and below the insole (502), and the upper part can be folded inside the sock to make direct contact with the ankle.

[0102] Next, when the shoe with the substrate (100) combined is worn and the tip (400) is elastically brought into contact with the ground, the static electricity accumulated in the body can flow to the ground through the band (200), the substrate (100), the elastic portion (300), and the tip (400).

[0103] FIG. 13 is a perspective view showing a disassembled and assembled state of a fourth embodiment of the present invention, and FIG. 14 is a cross-sectional view showing a fourth embodiment of the present invention. The shoe detachable grounding device of the fourth embodiment of the present invention is configured to include a substrate (100) made of a conductive material and fastened to the sole (500) and the upper (501) of the shoe, a conductive flexible band (200) fastened to the substrate (100) through the upper (501) and in contact with the ankle, and a conductive elastic portion (300) that allows a conductive tip (400) in contact with the ground to be elastically coupled to the substrate (100).

[0104] The above substrate (100) has a sole fixing hole (101) formed in a rectangular shape at the bottom to guide a screw-shaped sole fixing member (100a) to be fixed to the shoe sole (500) placed where both feet meet, and an upper fixing hole (102) formed in a rectangular shape at the top to guide an upper fixing member (100b) to be fixed to the shoe upper (501).

[0105] The above upper fixing member (100b) is composed of a head portion (100c) and a hollow pin, and fixes the band (200), the upper portion (501), and the substrate (100) by having the fixing pin inserted into the pin and pressed, and the head portion (100c) can come into contact with the foot inside the shoe.

[0106] The above upper fixing member (100b) may be formed by drilling a hole in the band (200) and the upper (501) and then riveting the band (200), the upper (501) and the substrate (100) to be fixed thereto.

[0107] The above elastic part (300) is formed integrally with the substrate (100) by being folded in a zigzag pattern on a plane, and the lower end is integrally provided with a tip (400) that comes into contact with the ground.

[0108] The lower part of the above band (200) is configured to wrap around the insole (502), and the upper part can be folded into both feet and have a built-in core material so that it remains in direct contact with the ankle.

[0109] The lower part of the above substrate (100) may be configured to include a grounding portion (110) that is placed on the bottom surface of the sole (500) and directly touches the ground together with the sole (500).

[0110] The fourth embodiment of the present invention configured in this manner operates as follows.

[0111] First, a sole fixing member (100a) is inserted into the sole fixing hole (101) of the lower part of the substrate (100) to fix it to the shoe sole (500), and a hole is drilled into the shoe upper (501) and band (200) corresponding to the upper fixing hole (102) of the upper using an awl or the like, into which a pin of the upper fixing member (100b) can be inserted.

[0112] Next, the head portion (100c) is caught on the band (200) and positioned inside the shoe, and the upper fixing member (100b) is inserted into the band (200), the upper (501), and the sole fixing hole (101), and then a fixing pin is inserted into the hollow pin and pressed to fix the substrate (100) vertically to the sole (500) and the upper (501) formed on the inner facing surfaces of both shoes, so that it can be applied to various types of shoes.

[0113] Continuing, the lower part of the band (200) can be wrapped above and below the insole (502), and the upper part can be folded inside the sock to make direct contact with the ankle.

[0114] Next, when the shoe with the substrate (100) combined is worn and the tip (400) is elastically brought into contact with the ground, the static electricity accumulated in the body can flow to the ground through the band (200), the substrate (100), the elastic portion (300), and the tip (400).

[0115] According to the shoe detachable grounding device of the present invention as described above, when the conductive substrate is fastened to the sole and upper of the shoe, it is placed perpendicular to the ground, so that the tip portion elastically contacts the ground, can be applied to various types of shoes, and since the conductive band in contact with the foot magnetically adheres to the substrate, it has the effect of making it convenient to wear the shoe.
