The present disclosure relates to a cold protection cover for a walking stick, and more particularly, to a cold protection cover for the walking stick that is mounted on the walking stick to enclose the handle of the walking stick such that the walking stick may be easily gripped even in severely cold weather.
A walking stick is a stick that assists users in walking, and is also called a cane. It is used by the elderly, the physically disabled, hikers, and travelers, and sometimes used by high-ranking people as a symbol of authority or for self-defence.
In general, a walking stick includes a handle corresponding to a part gripped by the user and a straight rod part connected to the handle. In extremely cold weather in, for example, winter, the handle becomes quite cold. In particular, the elderly who must use a walking stick indispensably are physically very frail and more vulnerable to such an environment. Therefore, there is a need to address the aforementioned issue.
Korea Utility No. 20-0195945 discloses a conventional technology for a cold protection cover for a motorcycle, which is not related to a walking stick but is capable of protecting drivers driving a motorcycle in bad weather.
Therefore, the present disclosure has been made in view of the above problems, and it is one object of the present disclosure to provide a cold protection cover for a walking stick, which allows a user to stably grip a handle of the walking stick even in cold weather in, for example, winter.
It is another object of the present disclosure to provide a cold protection cover for a walking stick which is capable of firmly maintaining coupling between the walking stick and the cold protection cover due to its unique structure and shape.
In accordance with one aspect of the present disclosure, provided herein is a cold protection cover mounted on a walking stick to enclose a handle of the walking stick. The cold protection may include a body having an inner space to accommodate the handle of the walking stick, an upper opening provided in an upper part of the body, an grip insertion slit provided on one side of the body and forming an insertion hole, the walking stick being inserted into the insertion hole, a lower opening provided in a lower part of the body and allowing the body of the walking stick to pass therethrough, a first opening/closing means configured to open and close the grip insertion slit, and a second opening/closing means configured to open and close the lower opening.
In addition, the grip insertion slit may extend inwardly from one side of the body and be provided on one lower part constituting one side lower part. The lower part may have an inclined part inclined downward and inward.
The upper opening may have one upper end at one end of the upper opening and an opposite upper end at an opposite end of the upper opening. The one upper end and the opposite upper end may be formed in a round shape.
In addition, the first opening/closing means and the second opening/closing means may be Velcro tapes. The first opening/closing means may be coupled to an inside of the body.
According to the present disclosure having the above configuration and characteristics, the handle of the walking stick may be stably gripped even in cold weather in, for example, winter.
In addition, due to its unique structure and shape of the cold protection cover, coupling between the walking stick and the cold protection cover may be firmly maintained.

The present disclosure relates to a cold protection cover for a walking stick 2, and more particularly, to a cold protection cover for the walking stick 2 that is mounted on the walking stick 2 to enclose the handle 21 of the walking stick 2 such that the walking stick 2 may be easily gripped even in severely cold weather.
In addition, unless otherwise specified in the present disclosure, one side and one end refer to the left side and left end, and an opposite side and an opposite end refer to the right side and right end.
First, as shown in
Next, the body 1 includes an upper opening 11 having an open top and provided in an upper portion of the body 1 to cover the handle 21 and a portion of the body 22. The structure of the body 1 will be described in detail later. As described above, the body 1 is arranged close to the handle 21 of the walking stick 2 to protect the walking stick from the cold weather such that the user may easily grip the walking stick 2 by putting his hand into the upper opening 11.
Next, as shown in
Next, as shown in
In addition, an upper inclined part 15A may be provided between the one upper end 11A and the one side part 12A, which may not only reduce the space inside the body 1 to a compact size to maximize thermal efficiency, but also allow the walking stick 2 to enter smoothly through an insertion hole 161 to be coupled to the body 1.
Next, as shown in
In addition, an grip insertion slit 16 that is provided on one side of the body 1 and forms an insertion hole into which the walking stick 2 is inserted will be described in detail. The grip insertion slit 16 extends inward from the one side part 12A of the body 1 to one lower part 13A, which are forms one side lower part. In addition, as described in
As the grip insertion slit 16 is formed to be inclined, the handle 21 of the walking stick 2 may be easily inserted into the body 1. More specifically, if the inclination is not formed at all, the waking stick 2, which is relatively long, should be moved upward with the height thereof maintained, and then the body 22 should be inserted into the lower opening 14, which will be described later, to couple the waking stick 2 with the body 1. Accordingly, the coupling operation is quite cumbersome. In particular, considering that the waking stick 2 is an item used by people with reduced mobility such as the elderly, the above effect may be further emphasized.
In this regard, according to the present disclosure, the lower part 13A has an inclined part having a predetermined slope. Accordingly, when the long walking stick 2 is inserted into the body 1, it is moved while obtaining a height gain in the inclination direction, rather than maintaining the height of the walking stick 2.
Here, the height gain refers to a reduced amount of height by which the walking stick 2 is less lifted upward as the walking stick 2 is inclined in an inclination direction.
More specifically, in coupling the body 1 and the walking stick 2, when the lower part of the walking stick 2 passes through the grip insertion slit 16 after the handle 21 of the walking stick 2 is inserted into the aforementioned grip insertion slit 16, the lower part of the walking stick 2 is moved into the lower opening 14 such that the body and the walking stick may be coupled.
Here, the lower opening 14 refers to an element which is provided to the lower part of the body 1 and through which the body 22 of the walking stick 2 passes.
Next, the grip insertion slit 16 may include a first opening/closing means 31 to open and close the open part of the grip insertion slit 16. In one embodiment, the first opening/closing means 31 may be a Velcro tape.
In addition, the body 1 includes a lower opening 14 protruding downward from the lower part and having an open center. The lower opening 14 may include a second opening/closing means 32 to opening closed the open part of the lower opening 14. In one embodiment, the second opening/closing means 32 may be a Velcro tape.
As shown in
In addition, as shown in
In addition, the upper and lower parts of the first opening/closing means 311 are defined as follows. Based on
As shown in
The width of the part of the first opening/closing means closer to the outermost side of the insertion hole 16 is formed wider, which makes it more difficult to detach the first opening/closing means from the outermost side. In particular, this effect may be further maximized for beginners of mountaineering or hikers who mainly enjoy rough hiking.
As shown in
In addition, in one embodiment, the second opening/closing means may be a Velcro tape including a D-type ring and a webbing string, which may completely seal the lower opening 14, effectively preventing the body 1 and the walking stick 2 from being separated.
The cold protection cover for a walking stick according to the present disclosure further includes a functional additive. The addition of the functional additive may suppress the generation of organic halogen compounds and nitrogen oxides present on the outer surface of the cold protection cover, and may also obtain antibacterial and deodorizing effects. In particular, it may ultimately protecting elderly people with weak immune systems, considering that the age group using the walking stick is the elderly. In addition, the functional additive may be included by immersing the cold protection cover for the walking stick according to the present disclosure in the functional additive.
The functional additive includes 100 parts by weight of a binder, 12 parts by weight of titanium tetraisopropoxide, 0.3 parts by weight of platinum ion, 12 parts by weight of polyphenylmethylsiloxane, 40 parts by weight of polydimethoxysilane, 5 parts by weight of polychlorinated phosphonitrile, 3.8 parts by weight of isopto, 2 parts by weight of carbonate apatite, 0.1 parts by weight of calcium phosphate, and 0.1 parts by weight of hydroxyapatite.
Silicon alkoxide may be used as the binder. Hereinafter, the content of each composition of the functional additive is based on 100 parts by weight of the binder.
Next, the titanium tetraisopropoxide is a precursor of titanium dioxide, which is stirred with platinum ions, which will be described later, to produce platinum-titanium dioxide with a reduced energy gap between the conduction band and the balance band of titanium dioxide.
Therefore, the platinum-titanium dioxide may be active not only in the ultraviolet region but also in the visible light region. In the active state, electrons and holes move to the surface and combine with oxygen and hydroxyl groups to form radicals, thereby removing nitrogen oxides and organic halogen compounds (and obtaining the deodorization and antibacterial effects described above).
In addition, titanium tetraisopropoxide with a formula of CH32CHO2TiC5H7O22 may be used. The titanium tetraisopropoxide may be contained as much as 12 parts by weight. When the titanium tetraisopropoxide is used in an amount of less than 12 parts by weight, nitrogen oxides and organic halogen compounds cannot be effectively removed. When it is used in an amount exceeding 12 parts by weight, it is difficult to form a narrow energy band gap.
Next, platinum ions are stirred with the titanium tetraisopropoxide to produce platinum-titanium dioxide, and may be obtained from chlorobaekgeumsan or the like. The stirring process may conform to a typical method. The platinum ions are contained as much as 0.3 parts by weight. Platinum ions cannot effectively reduce the energy band gap between platinum and titanium dioxide when used in an amount less than 0.3 parts by weight, and are not economical when used in an amount exceeding 0.3 parts by weight.
Next, polyphenylmethylsiloxane is a material that is stirred with the above platinum-titanium dioxide to suppress the active state of platinum-titanium dioxide. Polyphenylmethylsiloxane prevents the platinum-titanium dioxide from rapidly oxidizing the other constituents upon immersion, and it is preferable to add the same amount as the platinum-titanium dioxide.
Next, polydimethoxysilane and polychlorinated phosphonitrile are used as substances that decompose the polyphenylmethylsiloxane. They are added after stirring platinum-titanium dioxide and polyphenylmethylsiloxane. While the polyphenylmethylsiloxane is slowly decomposed, the platinum-titanium dioxide, whose active state has been suppressed, can be oxidized after the immersion is completed. Preferably, 40 parts by weight of polydimethoxysilane and 5 parts by weight of polychlorinated phosphonitrile are used. If the amount of polydimethoxysilane used is less than 40 parts by weight, and the amount of polychlorinated phosphonitrile used is less than 5 parts by weight, the decomposition rate of the polyphenylmethylsiloxane may be too slow, leading to a decrease in oxidizing power of platinum-titanium dioxide. If the amount of polydimethoxysilane used exceeds 40 parts by weight, and the amount of polychlorinated phosphonitrile used exceeds 5 parts by weight, the decomposition rate of the polyphenylmethylsiloxane may be too fast, and physical properties may be adversely affected due to the strong oxidizing power of platinum-titanium dioxide.
Next, isopto is added to increase emulsion stability, and it is preferable to use 3.8 parts by weight of isopto. When the amount used is less than 3.8 parts by weight, the emulsification property may not be improved. When the amount used exceeds 3.8 parts by weight, economic feasibility and physical properties may be deteriorated.
Next, carbonate apatite, calcium phosphate, and hydroxyapatite are substances that are softened or dissolved in an acidic atmosphere. Before the functional additive comes into contact with acid dyes applied to the outer surface of the cold protection cover, the carbonate apatite, calcium phosphate, and hydroxyapatite may protect the worker by covering the isopto, which may have a harmful effect on humans (strong irritation when it enters the eyes, etc.). After the functional additive comes into contact with acid dyes, the emulsion stability effect of the isopto may be exhibited as the carbonate apatite, calcium phosphate, and hydroxyapatite are softened or decomposed. In addition, 2 parts by weight of carbonate apatite, 0.1 parts by weight of calcium phosphate, and 0.1 parts by weight of hydroxyapatite may be contained. When they are used below the above range, it is difficult to suppress the harmful properties of the isopto. When they exceed the above range, it is difficult to obtain the emulsifying effect of the isopto. Of course, an acid dye should be used for the cold protection cover.
Various modifications and changes can be made to the present disclosure described above with reference to the accompanying drawings by regularly trained technician. Such modifications and changes should be interpreted as being within in the scope of the present disclosure.
