Description

Earthing cane device using spring wire cable

[0001] The present invention relates to an earthing device, and more specifically, to an earthing cane (stick) device using a spring wire cable.

[0002] This application claims priority based on Utility Model Application No. 20-2025-0001076 filed in the Republic of Korea on June 20, 2025, and all contents disclosed in the specification and drawings of said application are incorporated into this application.

[0003] Earthing means connecting to the earth, and in Korean, it is called grounding. The effects of earthing on the human body began to be known starting with the publication of the book "Earthing: Contact with the Earth Heals," co-authored by American electrician Clint Ober and cardiologist Dr. Steven Sinatra, among others, in 2010.

[0004] Some studies suggest that earthing can help with deep sleep. When high levels of the stress hormone cortisol persist, the sympathetic nervous system becomes excessively tense, causing sleep disorders. Research results have been published showing that when earthing was performed during deep sleep on subjects with sleep disorders, circadian cortisol levels normalized, and the quality of sleep improved as cortisol levels decreased during nighttime sleep.

[0005] In addition, research results have been published stating that free electrons conducted into the body through earthing surround the outer walls of red blood cells, invigorating blood flow, which facilitates oxygen supply to various parts of the body and contributes to maintaining a healthy state of the body.

[0006] Barefoot walking began to gain popularity as it became known that the Earth is a treasure trove of free electrons and that free electrons are conducted into the body simply by walking barefoot on the ground. However, as people wear shoes and roads are paved with asphalt, opportunities to walk on the ground are gradually decreasing, and in the middle of winter, it becomes difficult to walk on bare ground because the feet get cold.

[0007] The present specification aims to provide an earthing cane device that allows the palm of the cane (stick) used by a user when walking or hiking to be grounded as an alternative to barefoot walking.

[0008] This specification is not limited to the problems mentioned above, and other problems not mentioned will be clearly understood by a person skilled in the art from the description below.

[0009] An earthing cane device according to the present specification for solving the above-mentioned problem comprises: a grounding contact portion located at one end and formed of a conductive material; a grounding handle portion located at the other end, having a hollow interior and formed of a conductive material; a plurality of connecting sticks located between the grounding contact portion and the grounding handle portion and having a hollow interior; and a grounding connecting wire portion located inside the grounding handle portion and the plurality of connecting sticks, having one end electrically connected to the grounding contact portion and the other end electrically connected to the grounding handle portion; wherein at least a portion of the grounding connecting wire portion may be formed as a spring structure.

[0010] According to one embodiment of the present specification, the ground connection line may include: a spring wire cable, one end of which is electrically connected to the ground handle portion; and a conductive wire, one end of which is electrically connected to the other end of the spring cable and the other end of which is electrically connected to the ground contact portion.

[0011] According to one embodiment of the present specification, the ground connection line may include a spring wire cable or wire having a relatively lower stiffness than the conductive wire, with one end electrically connected to the conductive wire and the other end electrically connected to the ground contact part.

[0012] An earthing cane device according to an embodiment of the present specification further comprises: a wrist band portion having at least one conductive portion on one surface to contact the wrist; and a band connecting line electrically connecting the wrist band portion and the grounding handle portion; wherein the grounding handle portion includes a first grounding button connecting portion electrically connected to the grounding connecting line portion on one surface; and the wrist band portion includes a second grounding button connecting portion electrically connected to the conductive portion; and wherein one end of the band connecting line may be connected to the first grounding button connecting portion and the other end may be connected to the second grounding button connecting portion.

[0013] For example, the earthing cane device according to the present specification may include: a height-adjustable earthing cane comprising a grounding contact portion of a cane that contacts the ground and is made of a conductive material; a conductive cane grounding handle portion connected to the contact portion and the cane so that earthing occurs when the palm touches it; a plurality of connecting sticks located between the grounding contact portion and the grounding handle portion and having a hollow interior; and a grounding connecting wire portion that is connected by a wire to allow electricity to flow between the contact portion and the handle portion, wherein the connecting wire is a spring cable and fits inside the cylindrical part of the cane.

[0014] As another example, the earthing cane device according to the present specification may comprise a foldable earthing cane configured such that the middle of the cane is separated into 4 to 5 sections and foldable, comprising: a grounding contact portion of the cane that contacts the ground; a cane grounding handle portion that is conductive and connected to the contact portion and the cane so that earthing occurs when the palm touches it; and a grounding connection wire portion that is connected by a wire to allow electricity to flow between the contact portion and the handle portion, wherein the connecting wire is a spring cable and fits inside the cylindrical part of the cane.

[0015] Other specific details of the present invention are included in the detailed description and drawings.

[0016] According to one aspect of the present specification, a height-adjustable earthing cane device and a foldable earthing cane device can provide an earthing effect from the ground to the hand through a spring wire cable that electrically connects a grounding contact part and a grounding handle part inside.

[0017] In addition, the earthing cane device can be electrically connected to an external earthing device (such as a wristband) through a grounding button connector. Through this, the earthing effect is achieved not only by the earthing cane device but also by the external earthing device.

[0018] The effects of the present invention are not limited to those mentioned above, and other unmentioned effects will be clearly understood by a person skilled in the art from the description below.

[0019] FIG. 1 is a drawing illustrating an example of a height-adjustable earthing cane device according to one embodiment of the present specification.

[0020] FIG. 2 is a drawing illustrating an example of a foldable earthing cane device according to one embodiment of the present specification.

[0021] Figure 3 is a drawing illustrating an example of a foldable earthing cane device including five connecting sticks.

[0022] Figure 4 is a drawing illustrating an example in which a wrist band is connected to an earthing cane device through a grounding button connection and a band connection line.

[0023] The advantages and features of the invention disclosed herein, and the methods for achieving them, will become clear by referring to the embodiments described below in detail together with the accompanying drawings. However, this specification is not limited to the embodiments disclosed below and may be implemented in various different forms. These embodiments are provided merely to ensure that the disclosure of this specification is complete and to fully inform those skilled in the art (hereinafter referred to as "skilled in the art") of the scope of this specification, and the scope of rights of this specification is defined only by the scope of the claims.

[0024] The terms used herein are for describing the embodiments and are not intended to limit the scope of the claims herein. In this specification, the singular form includes the plural form unless specifically stated otherwise in the text. As used herein, "comprises" and / or "comprising" do not exclude the presence or addition of one or more other components in addition to the components mentioned.

[0025] Unless otherwise defined, all terms used herein (including technical and scientific terms) may be used in a meaning commonly understood by a person skilled in the art to which this specification pertains. Additionally, terms defined in commonly used dictionaries are not to be interpreted ideally or excessively unless explicitly and specifically defined otherwise.

[0026] Metal walking sticks are being released to alleviate the difficulties of walking barefoot in the middle of winter. Metal walking sticks provide a grounding effect when the user grips the handle.

[0027] However, conventionally released canes are difficult to adjust in height. As a result, users faced the inconvenience of having to carry the long cane in its extended state when using public transportation, as they could not fold it.

[0028] To resolve this, the earthing cane device must be height-adjustable like a regular cane that is not grounded, or be foldable for carrying.

[0029] However, for an earthing cane device to be grounded to the earth, it must use a method of continuous metal connection. Conventional height-adjustable canes utilize multiple aluminum sticks to ensure lightness and efficient height adjustment. Conventionally, to ensure stable connections between the aluminum sticks, plastic is included, or the aluminum is wrapped in insulating materials such as vinyl to prevent rust. Consequently, these height-adjustable canes have a structure that makes it difficult to establish a continuous electrical circuit between the contact point with the ground and the handle.

[0030] A simple solution to this problem is to form the contact points with the ground and the handle parts from a conductive metal material and connect them with a wire. However, when the height of the height-adjustable cane is reduced to the minimum, the long wire folds and gets stuck in the middle of the cane or does not fold properly.

[0031] In this specification, to solve the aforementioned problems, a spring wire cable is used to connect the ground contact part and the ground handle part with a wire. When the cane is folded, the spring wire cable contracts, and when it is unfolded, the spring wire cable can expand. Through this, the phenomenon of the wire getting pinched or not folding is eliminated, allowing the user to easily fold and unfold the cane.

[0032] This method has the advantage of allowing you to simply fold the earthing cane device and attach it to a backpack or similar item when using public transportation, eliminating the need to carry a long hiking stick.

[0033] In addition, as the weather becomes too cold, it may be difficult for the user to hold the earthing cane device with bare hands. The earthing cane device according to the present specification can connect a grounding button connection part included in the grounding handle part and a grounding wrist band part through a band connection line. Through this, even if the user holds the grounding handle part while wearing gloves, the wrist is grounded, allowing the user to receive an earthing effect from the earthing cane device.

[0034] The configuration of the wrist band portion described above is omitted in this specification because the applicant has previously filed a related invention (Application No.: 20-2024-0001035) and there are already released wrist bands. The wrist bands applicable to this patent are not limited to the above invention and include all conductive wrist bands that electrically connect the cane handle and the wrist to enable grounding.

[0035] Furthermore, the configurations of height-adjustable and folding canes do not refer to any specific method, as many types of canes have already been released as products. As the structure of each cane is widely known among those skilled in the art, a detailed description of the structure is omitted.

[0036] Unless otherwise specified in this specification, earthing cane devices include both height-adjustable earthing cane devices and foldable earthing cane devices.

[0037] Hereinafter, an earthing cane device according to the present specification will be described with reference to the attached drawings.

[0038] An earthing cane device according to one embodiment of the present specification may include a grounding contact portion, a grounding handle portion, a plurality of connecting sticks, and a grounding connecting wire portion.

[0039] FIG. 1 is a drawing illustrating an example of a height-adjustable earthing cane device according to one embodiment of the present specification. FIG. 1A is an example illustrating a state in which the length of the height-adjustable earthing cane device (10) is at its minimum, and FIG. 1B is an example illustrating a state in which the length of the height-adjustable earthing cane device (10) is at its maximum.

[0040] Referring to FIG. 1, the height-adjustable earthing cane device (10) according to the present specification may include a ground contact part (05), a ground handle part (01), a ground connection wire part (03), and a plurality of connection sticks (04-1 to 04-3).

[0041] The grounding contact portion (05) is located at one end of the height-adjustable earthing cane device (10) and may be formed of a conductive material (such as metal). When a user uses the height-adjustable earthing cane device (10), the grounding contact portion (05) may correspond to the part that comes into contact with the ground.

[0042] The grounding handle portion (01) is located at the other end of the height-adjustable earthing cane device (10) and may include a hollow inside. For example, the grounding handle portion (01) may have a cylindrical shape with an empty space (hollow) in the center inside, which is an example and is not limited to the cylindrical shape.

[0043] The grounding handle portion (01) may be formed of a conductive material. When a user uses the height-adjustable earthing cane device (10), the grounding handle portion (01) may correspond to the part that the user grasps with their palm.

[0044] A plurality of connecting sticks (06) are positioned between the ground contact portion (05) and the ground handle portion (01) and may contain a hollow inside. A plurality of connecting sticks (06) may be connected between the ground contact portion (05) and the ground handle portion (01). In FIG. 1, three connecting sticks (06-1 to 06-3) are shown, but this is an example and is not limited to the number shown.

[0045] The ground connection wire section (03) may be located inside the ground handle section (01) and a plurality of connection sticks (06). One end of the ground connection wire section (03) is connected to the ground contact section (05), and the other end may be connected to the ground handle section (01).

[0046] The ground connection wire (03) may correspond to a conductive wire. The ground contact part (05) and the ground handle part (01) may be electrically connected through the ground connection wire (03).

[0047] Additionally, the height-adjustable earthing cane device (10) may include at least one connecting part (04) that adjusts the overall height. The number of connecting parts (04) may be proportional to the number of connecting sticks.

[0048] According to one embodiment of the present specification, at least a portion of the ground connection line (03) may be formed as a spring structure. When a plurality of connection sticks move toward the ground handle (01), the ground connection line (03) may contract. When a plurality of connection sticks move away from the ground handle (01), the ground connection line (03) may expand. Through this, the ground connection line may be prevented from getting stuck or not folding, allowing the user to easily fold and unfold the cane.

[0049] FIG. 2 is a drawing illustrating an example of a foldable earthing cane device according to one embodiment of the present specification.

[0050] Referring to FIG. 2, the foldable earthing cane device (20) according to the present specification may include a grounding contact part (05), a grounding handle part (01'), a grounding connecting wire part (03'), and a plurality of connecting sticks (06'-1 to 06'-3).

[0051] The grounding contact portion (05') is located at one end of the foldable earthing cane device (20) and can be formed of a conductive material (such as metal). When a user uses the foldable earthing cane device (20), the grounding contact portion (05') may correspond to the part that comes into contact with the ground.

[0052] The grounding handle portion (01') is located at the other end of the foldable earthing cane device (20) and may contain a hollow interior. The grounding handle portion (01') may be formed of a conductive material. When a user uses the foldable earthing cane device (20), the grounding handle portion (01') may correspond to the part that the user grasps with their palm.

[0053] Multiple connecting sticks (06'-1 to 06'-3) are positioned between the ground contact portion (05') and the ground handle portion (01') and may include a hollow inside. Multiple connecting sticks (06'-1 to 06'-3) may be connected between the ground contact portion (05') and the ground handle portion (01'). Although three connecting sticks are shown in FIG. 2, this is an example and is not limited to the number shown.

[0054] The ground connection wire section (03') may be located inside the ground handle section (01') and a plurality of connection sticks (06'-1 to 06'-3). One end of the ground connection wire section (03') is connected to the ground contact section (05'), and the other end may be connected to the ground handle section (01').

[0055] The ground connection wire (03') may correspond to a conductive wire. The ground contact part (05') and the ground handle part (01') may be electrically connected through the ground connection wire (03').

[0056] Additionally, the foldable earthing cane device (20) may include at least one connecting part (04') that is detachable so that the length of the cane can be reduced and folded. The number of connecting parts (04') may be proportional to the number of connecting sticks.

[0057] According to one embodiment of the present specification, at least a portion of the ground connection line (03') may be formed as a spring structure.

[0058] Figure 3 is a drawing illustrating an example of a foldable earthing cane device including five connecting sticks.

[0059] In the example of FIG. 3, the foldable earthing cane device (20) may include five connecting sticks (06'-1 to 06'-4). Although five connecting sticks are shown in the example of FIG. 3, this is just one example, and the number of connecting sticks may vary depending on the design, such as four.

[0060] According to one embodiment of the present specification, when the number of connection sticks is greater than or equal to a preset number, the ground connection line may include a spring wire cable (03') and a conductive wire (07').

[0061] The spring wire cable (03') may refer to a wire in which at least a portion is formed as a spring structure. One end of the spring wire cable (03') may be connected to the grounding handle portion (01').

[0062] One end of the conductive wire (07') can be connected (08') to the other end of the spring wire cable (03'). The other end of the conductive wire (07') can be connected to the ground contact (05').

[0063] For example, if the foldable earthing cane device includes 4 to 5 connecting sticks, the grounding contact part (05') and the grounding handle part (01') are not connected only by a spring wire cable (03'), but the connecting sticks at the bottom, excluding the grounding handle part (01'), can be connected and secured by a conductive wire (07'). A spring wire cable (03') can be connected between the grounding handle part (01') and the conductive wire (07').

[0064] Multiple connecting sticks (06'-1 to 06'-4) can be separated from each other. At this time, the user can reduce the length of the foldable earthing stick device (20) by folding a portion of the conductive wire (07') exposed around the boundary of each connecting stick.

[0065] The conductive wire (07') may have relatively higher rigidity than the spring wire cable (03'). If the conductive wire (07') has relatively lower rigidity than the spring wire cable (03') and / or a commonly used general wire, the conductive wire (07') may stretch or break when the connecting stick is folded and unfolded. If the conductive wire (07') stretches or breaks, the fixing force of the foldable earthing stick device (20) may become relatively weaker than before the conductive wire (07') stretches. Additionally, if the conductive wire (07') breaks, the electrical connection between the grounding handle part (01') and the grounding contact part (05') may be severed, preventing earthing. To prevent this, it is desirable that the conductive wire (07') be formed with relatively higher rigidity than the spring wire cable (03') and / or a general wire.

[0066] According to one embodiment of the present specification, a foldable earthing cane device (20) may include a first connecting stick (06'-1) connected to a grounding handle portion (01') and a second connecting stick (06'-2) connected to the first connecting stick (06'-1). The second connecting stick (06'-2) may be connected to a grounding contact portion (05') or connected to another connecting stick.

[0067] For example, if there are two connection sticks, the second connection stick (06'-2) can be connected to the ground contact (05'), and if there are two or more connection sticks, the second connection stick (06'-2) can be connected to the third connection stick (06'-3).

[0068] The second connecting stick (06'-2) is inserted into the first connecting stick (06'-1) and can move in a direction closer to or further away from the ground handle part (01').

[0069] The interior of the second connecting stick (06'-2) may include a wire fixing pin (08'-2) for fixing a conductive wire (07'). The conductive wire (07') can be fixed to the second connecting stick (06'-2) by the wire fixing pin (08'-2). As a result, the conductive wire (07') can move together with the second connecting stick (06'-2). At this time, the wire connection part (09') to which the conductive wire (07') and the spring wire cable (03') are connected can move in the same direction as the second connecting stick (06'-2).

[0070] When the second connecting stick (06'-2) moves toward the grounding handle (01'), the wire connecting part (09') moves toward the grounding handle (01'), so that the spring wire cable (03') can contract. When the second connecting stick (06'-2) moves away from the grounding handle (01'), the wire connecting part (09') moves away from the grounding handle (01'), so that the spring wire cable (03') can expand.

[0071] Through this, the phenomenon of the grounding connection wire getting stuck or not folding is eliminated, allowing the user to easily fold and unfold the cane.

[0072] At this time, the position of the second connecting stick (06'-2) can be fixed by the height adjustment fixing pin (08'-1) included in the first connecting stick (06'-1).

[0073] According to one embodiment of the present specification, the ground connection line portion (03') may include a spring wire cable (not shown) and / or a wire (not shown) having a relatively lower rigidity than the conductive wire (07'), with one end electrically connected to a conductive wire (07') and the other end electrically connected to a ground contact portion (05'). At this time, the spring wire cable and / or the wire may be located in a portion directly connected to the ground contact portion (05').

[0074] When a high-rigidity conductive wire (07') is directly connected to the ground contact (05'), the ground contact (05') may be pulled or pushed by the conductive wire (07') when the connection stick is folded or unfolded. In this case, a physical defect may occur between the ground contact (05') and the connection stick.

[0075] When the spring wire cable and / or wire is connected to the other end of the conductive wire (07'), the spring wire cable and / or wire may stretch or contract when the connecting stick is folded or unfolded, thereby weakening the force applied to the ground contact part (05'). Through this, physical defects between the ground contact part (05') and the connecting stick can be prevented.

[0076] Referring again to FIGS. 1 to 3, the grounding handle portion (01, 01') may include a grounding button connection portion (02, 02') that is electrically connected to a grounding connection wire portion (03, 03') on one side. The grounding button connection portion (02, 02') is an electrical terminal to which a wire is connected and is not limited by a specific type of terminal.

[0077] A band connecting wire that electrically connects the grounding button connecting portion (02, 02') and the wristband portion worn on the user's wrist may be connected to the grounding button connecting portion (02, 02'). The band connecting wire may include an electrical terminal connected to the grounding button connecting portion (02, 02').

[0078] Figure 4 is a drawing illustrating an example in which a wrist band is connected to an earthing cane device through a grounding button connection and a band connection line.

[0079] Referring to FIG. 4, the earthing cane device may include a band connecting line (C3) and a wrist band portion (C4). The band connecting line (C3) may be connected to a first grounding button connecting portion (C2) included in the grounding handle portion (C1) and a second grounding button connecting portion (C2') included in the wrist band portion (C4). The band connecting line (C3) may electrically connect the grounding handle portion (C1) and the wrist band portion (C4).

[0080] According to one embodiment of the present specification, the wrist band portion (C4) may include at least one conductive portion on one surface to contact the wrist. The conductive portion may be formed of a conductive material.

[0081] For example, the conductor may be located in the part where the second ground button connection part (C2') is located. When the user wears the wristband part (C4), the user's wrist may be electrically connected to the earthing cane device through the conductor, the second ground button connection part (C2'), and the band connection line (C3).

[0082] As another example, the conductor may be located in a part where the second ground button connection part (C2') is not located. The conductor may be electrically connected to the second ground button connection part (C2') using a wire, conductive thread, etc., included in the wristband part (C4).

[0083] As another example, the wrist band portion (C4) may include a first conductor portion and a second conductor portion and a band portion, with a metal plate installed on one surface, as described in the prior art previously filed by the applicant (Application No.: 20-2024-0001035).

[0084] The first conductor portion and the second conductor portion may be located at points spaced apart from each other within the circle formed by the wrist band portion (C4). At this time, the metal plate of the first conductor portion and the metal plate of the second conductor portion may be electrically connected through a conductive thread or fiber.

[0085] The first conductor part and / or the second conductor part may include a ground button connection part to which a band connection line (C3) is connected.

[0086] As another example, the entire wrist band portion (C4) may be formed of a conductive material such as a metal plate or a conductive fiber. In this case, the entire wrist band portion (C4) may correspond to a single conductive portion.

[0087] The structure of the wrist band portion (C4) described above is an example and is not limited by the above structures, and the wrist band portion (C4) can be formed in various structures such that when a user wears the wrist band portion (C4), the user's wrist, the wrist band portion (C4), the second grounding button connection portion (C2'), the band connection line (C3), and the earthing cane device can be electrically connected.

[0088] In this specification, the grounding handle and the connecting stick are illustrated as having a cylindrical shape, but this is merely an example and can be manufactured in various forms.

[0089] Although embodiments of this specification have been described above with reference to the attached drawings, those skilled in the art to which this specification pertains will understand that the present invention may be implemented in other specific forms without altering its technical concept or essential features. Therefore, the embodiments described above should be understood as illustrative in all respects and not restrictive.
