Description

Technical Field

[0001] The present invention relates to a ventilation device, and more particularly, to a buttock ventilation device that minimizes local irritation to specific body parts such as the anus, maximizes ventilation effects, reduces foreign body sensation, and has excellent deformability, fixing force, wearing feel, and aesthetic appearance even if the user's body characteristics vary and change, thereby enabling obese people and those who work in sedentary jobs or sweat a lot to live a comfortable life. Background Art

[0002] As an existing technology, functional men's underwear has been developed that has excellent wearing feel and mobility, and can remove moisture and odor generated around the scrotum through ventilation when worn, thereby preventing skin diseases such as eczema, and making metabolism and blood circulation smooth, thereby improving health functions (see Korean Patent Publication No. 2017-0082946).

[0003] However, if Figure 14 As shown, the functional male underwear is sewn with a triangular mesh cloth 110 to form a ventilation hole at a virtual triangle position connecting the scrotum and perineum on both sides, and a plurality of far-infrared emitters 120 are arranged at predetermined intervals on one side of the mesh cloth.

[0004] However, the above-mentioned functional men's underwear only considers the centralized ventilation of specific parts of the body, and does not consider the ventilation restriction caused by the overlap of the gluteal groove. In addition, since the mesh cloth 110 for ventilation needs to be attached together when making the underwear, the production cost of the underwear increases, and the underwear needs to be discarded when its service life has expired.

[0005] As another prior art, an anal hygiene tool has been developed that prevents eczema that may occur around the anus by removing moisture generated in the anus, and prevents the surface of the hygiene tool from being damaged by friction around the anus during exercise or walking, resulting in the generation of foreign matter (see Korean Utility Model Authorization No. 0461960).

[0006] like Figure 15 As shown, the above-mentioned anal sanitary tool includes: a streamlined main body 10, in which two side surfaces 12 of a main body 11 made of elastic synthetic resin are symmetrical to each other, and a convex surface 13 is formed so that the centers of the two side surfaces protrude; a ventilation part 20, in which a plurality of ventilation holes 21 are formed on the two side surfaces of the main body.

[0007] However, the anal hygiene tool is not only difficult to fix to a specific part of the body, but also may produce unexpected side effects due to stimulation by the protrusion 15, so it is not suitable for ordinary people except those with anal diseases. Summary of the Invention

[0008] Technical Problems to be Solved by the Invention

[0009] The present invention is proposed to solve the problems of the above-mentioned prior art, and its purpose is to provide a buttocks ventilation device as follows: that is, it takes into account the ventilation restriction caused by the partial overlap of the buttocks (the two sides of the buttocks that are open and close to each other) as a whole, rather than only considering the concentrated ventilation of specific parts of the body. Therefore, there is less foreign body sensation, the ventilation effect is maximized, the price is low, and even if the user has various physical characteristics and changes, its deformability, fixing force, wearing feel, and appearance are excellent. Therefore, it can not only be stably inserted and fixed in the buttocks (skin), but also because it does not only stimulate specific local parts, it can prevent unexpected side effects, so that modern people who spend more time sitting can widely use it.

[0010] Technical Solution

[0011] In order to achieve the above-mentioned purpose, the buttocks ventilating device of the present invention is characterized in that it includes: a ventilation frame, which is made of elastic material and is inserted along the buttocks groove along the length direction to open the buttocks groove; the above-mentioned ventilation frame includes: an elliptical frame, a plurality of slender frames are arranged in an elliptical shape at intervals to form an elliptical cross-section, and a straight frame, a slender frame is arranged in a manner of being spaced along the outer circumference of the elliptical frame and laterally passing through the plurality of elliptical frames so that the above-mentioned plurality of elliptical frames are connected to each other.

[0012] The present invention is characterized in that a soft frame made of soft material is used in a dispersed manner in the above-mentioned elliptical frame. When worn, the above-mentioned soft frame bends, so that the entire appearance forms a gentle arc.

[0013] The present invention is characterized in that when the ventilation frame is worn by being divided into a plurality of frames, the entire appearance of the ventilation frame forms a gentle arc.

[0014] The present invention is characterized in that the ventilation frame is chamfered (profiled edge) so that the size of the elliptical frames arranged at both ends gradually becomes smaller and is inserted from above the anus across the entire gluteal groove.

[0015] The present invention is characterized in that a long hole-shaped opening is formed by cutting an elliptical frame and a straight frame, the long hole-shaped opening is longitudinally passed through the upper and lower sides of the ventilation frame, and a long hole open frame is formed along the edge of the long hole-shaped opening.

[0016] The present invention is characterized in that a linear opening is formed by cutting the upper and lower parts of the ventilation frame along the entire length direction, a linear open frame is formed along the edge of the linear opening, and a connecting frame is formed for connecting the divided elliptical frames to each other.

[0017] The present invention is characterized in that the ventilation frame is rounded so that the size of the elliptical frame arranged at the rear end portion gradually becomes smaller.

[0018] The present invention is characterized in that it further comprises: a ventilation outer skin made of fiber material, covering the entire exterior of the ventilation frame to prevent skin from directly contacting the ventilation frame.

[0019] The present invention is characterized in that the ventilation frame is inserted from above the anus in a manner spanning the entire gluteal groove.

[0020] The present invention is characterized in that the ventilation frame further comprises a slender reinforcement frame arranged along an oblique direction, and the ventilation outer skin is provided with a fixing component that can be detached from the underwear or is integrally formed with the underwear.

[0021] Beneficial effects

[0022] The hip ventilation device of the present invention as described above exhibits the following effects.

[0023] 1) Its skeleton is composed of a ventilation frame consisting of an elliptical frame and a straight frame that are as slender as an umbrella rib, which minimizes local irritation to specific body parts such as the anus and maximizes ventilation effect.

[0024] 2) According to the embodiment, when a long hole-shaped opening or a straight-line opening is also provided, local irritation and pressure exerted on specific body parts such as the anus are minimized, and the barrier-free ventilation effect is maximized.

[0025] 3) According to the embodiment, the dispersed soft material can be freely deformed to the left and right or divided into multiple segmented frames to move freely to the left, right, front and back independently, so as to minimize local stimulation to specific body parts such as the anus and maximize the ventilation effect.

[0026] 4) Considering that the user's gluteal groove gradually narrows towards the coccyx, when the ventilation frame is rounded to gradually become thinner towards the coccyx, the problem of the lines being exposed due to its protrusion to the outside can be solved, making the appearance more slender and the wearing feel excellent.

[0027] 5) When the entire garment is covered with a ventilated outer skin, it can be inserted from just above the anus to the front along the entire gluteal groove, with the feel of underwear, in a sandwiched manner, with little foreign body sensation and excellent wearing feel, thus enabling obese people and modern people who sit for long periods of time or sweat a lot to live a comfortable life.

[0043] Hereinafter, the preferred embodiment that can specifically achieve the purpose of the present invention will be described in detail with reference to the accompanying drawings. When describing this embodiment, the same names are used for the same structures and additional description thereof will be omitted.

[0044] Figure 1 is a perspective view showing a ventilation frame of a buttock ventilating device according to the present invention, Figure 2 is a cross-sectional view showing a buttock ventilation device according to the present invention, Figure 3 1 is a diagram showing a usage state of the buttock ventilation device according to the present invention.

[0045] like Figure 1 and Figure 2 As shown, the hip ventilating device of the present invention includes a ventilation frame 100 .

[0046] The ventilation frame 100 is made of elastic synthetic resin material and includes an elliptical frame 110 and a linear frame 120 .

[0047] The elliptical frame 110 is formed by a plurality of slender frames like umbrella ribs arranged at intervals in a substantially elliptical shape.

[0048] The linear frame 120 is configured as follows: a thin and elongated frame like an umbrella rib is spaced along the outside of the elliptical frame and laterally passes through the plurality of elliptical frames and is configured in a slightly curved manner to connect the plurality of elliptical frames 110 to each other.

[0049] The ventilation frame 100 is formed by combining an elliptical frame 110 and a linear frame 120 to form a horizontal and vertical frame, and at the same time forms an elliptical (longitudinal) cross section, so that the entire appearance forms a gentle arc.

[0050] In order to maximize ventilation efficiency, all parts of the ventilation frame 100 except the elongated elliptical frame 110 and the linear frame 120 are formed as open spaces, and ventilation is achieved in the inner space including both ends and the outer peripheral surface.

[0051] like Figure 4 As shown, of course, the oval frame 110 and the straight frame 120 can be spaced apart or used in greater numbers (in order to maintain proper elasticity and bone structure) as required. Figure 4 , the elliptical frame 110 is implemented in a manner that can be divided into a horizontal and vertical frame).

[0052] In addition, although not specifically shown in the drawings, in order to reinforce the elliptical frame 110 and the linear frame 120 , the ventilation frame 100 may further include a plurality of elongated reinforcement frames arranged along an oblique direction.

[0053] like Figure 3As shown, the ventilation frame 100 is inserted along the gluteal groove (skin) in the length direction to open the gluteal groove. At this time, in order to prevent unpredictable side effects from being generated by stimulating only specific body parts such as the anus, the ventilation frame 100 is preferably inserted from above the anus across the entire gluteal groove (in the case of men, until in front of the scrotum).

[0054] In other words, after the ventilation frame 100 is inserted along the gluteal groove, its lower portion is additionally supported by underwear such as underwear (and a fixing component pulled by a rope to be described below), so it can be stably located in the gluteal groove (skin).

[0055] And, as Figure 2 In an embodiment, the present invention may further include a ventilation outer skin 200 made of fiber material, covering the entire exterior of the ventilation frame 100 to prevent the skin, ie, the buttock groove, from directly contacting the ventilation frame 100.

[0056] The ventilation outer skin 200 can be manufactured separately from the underwear, or can be integrally formed with the underwear (by sewing, etc.).

[0057] The ventilation outer skin 200 is preferably made of functional fibers that are mainly used in underwear materials for ventilation, and may also be made of pure cotton so that the skin does not feel a foreign body sensation.

[0058] In addition, the ventilation outer skin 200 may further include a fixing component 300 attached to the underwear to better maintain the state of being inserted into the gluteal groove together with the ventilation frame 100.

[0059] As the fixing member 300, various fixing means may be used, such as snaps or Velcro (also known as hook and loop), connecting rings, etc. applicable to underwear.

[0060] like Figure 5 As shown, a hip ventilating device according to an additional embodiment of the present invention includes a ventilation frame 100 .

[0061] The ventilation frame 100 is made of elastic synthetic resin material and includes an elliptical frame 110 and a linear frame 120 .

[0062] The elliptical frame 110 is formed by a plurality of slender frames like umbrella ribs arranged at intervals in a substantially elliptical shape.

[0063] The above-mentioned elliptical frame uses a soft frame 115 made of synthetic resin or synthetic rubber in a dispersed manner. When worn, the above-mentioned soft frame 115 can be further bent freely to the left and right, so that the entire appearance forms a gentle arc.

[0064] The linear frames 120 are arranged as thin and long frames like umbrella ribs, spaced apart along the outside of the elliptical frames and laterally passing through the plurality of elliptical frames, so as to connect the plurality of elliptical frames 110 to each other.

[0065] The ventilation frame 100 is formed by combining an elliptical frame 110 and a linear frame 120 to form a horizontal and vertical frame, and also forms an elliptical (longitudinal) cross section.

[0066] In order to maximize ventilation efficiency, all parts of the ventilation frame 100 except the elongated elliptical frame 110 and the linear frame 120 are controlled as open spaces, and ventilation is achieved in the internal space including both ends and the outer peripheral surface.

[0067] In order to provide a more comfortable wearing feeling, preferably, the ventilation frame 100 is chamfered so that the sizes of the elliptical frames 110 arranged at both ends gradually become smaller.

[0068] Of course, the intervals between the elliptical frame 110 and the linear frame 120 and the number of the elliptical frame 110 and the linear frame 120 can be increased or the number of the elliptical frame 110 and the linear frame 120 can be increased as needed to maintain proper elasticity and structure.

[0069] In addition, although not specifically shown in the drawings, in order to reinforce the elliptical frame 110 and the linear frame 120 , the ventilation frame 100 may further include a plurality of elongated reinforcement frames arranged along an oblique direction.

[0070] The above-mentioned ventilation frame 100 is inserted along the gluteal groove (skin) in the length direction to open the gluteal groove. At this time, in order to prevent unpredictable side effects from being generated by stimulating only specific body parts such as the anus, it is preferred that the ventilation frame 100 is inserted from above the anus across the entire gluteal groove (in the case of men, until in front of the scrotum).

[0071] Furthermore, as an additional embodiment of the present invention, Figure 6 As shown, a ventilation outer skin 200 may be further included. The ventilation outer skin 200 is made of fiber material and covers the entire exterior of the ventilation frame 100 to prevent the skin, ie, the buttock groove, from directly contacting the ventilation frame 100 .

[0072] The ventilation outer skin 200 may be manufactured separately from the underwear, or may be manufactured in a form fixed to the underwear (by sewing, etc.), so that the ventilation frame 100 may be stably located in the gluteal groove (skin).

[0073] The ventilation outer skin 200 is preferably made of functional fibers that are mainly used in underwear materials for ventilation, and may also be made of pure cotton so that the skin does not feel a foreign body sensation.

[0074] In addition, as another embodiment of the present invention, the ventilation outer skin 200 may further include a separate fixing component (not shown in the figure) attached to the underwear to better maintain the state of being inserted into the gluteal groove together with the ventilation frame 100.

[0075] On the other hand, as another embodiment of the present invention, Figure 7 and Figure 8 As shown, the ventilation frame 100 can be divided into a plurality of (about 3 to 5) (divided) frames. When worn, it can move freely to the left, right, front and back, so that the entire appearance naturally forms a gentle arc.

[0076] The split frames may be in a completely separated state so as to be able to move independently to the left, right, front and back, or they may be connected to each other by connecting members 116 such as ropes to restrict movement beyond a predetermined interval.

[0077] In this embodiment, in order to provide a more comfortable wearing feeling, it is also preferred that the ventilation frame 100 is chamfered so that the size of the elliptical frame 110 of the split frame arranged at both ends gradually becomes smaller.

[0078] like Figure 9 and Figure 10 As shown, according to an additional embodiment of the present invention, the hip ventilating device includes a ventilation frame 100 .

[0079] The linear frames 120 are arranged as thin and long frames like umbrella ribs, spaced apart along the outside of the elliptical frames and laterally passing through the plurality of elliptical frames, so as to connect the plurality of elliptical frames 110 to each other.

[0080] The ventilation frame 100 is formed by combining an elliptical frame 110 and a linear frame 120 to form a horizontal and vertical frame, and also forms an elliptical (longitudinal) cross section.

[0081] In order to maximize ventilation efficiency, all parts of the ventilation frame 100 except the elongated elliptical frame 110 and the linear frame 120 are controlled as open spaces, and ventilation is achieved in the internal space including both ends and the outer peripheral surface.

[0082] Among them, by cutting the elliptical frame 110 and the straight frame 120, long empty openings are formed on the upper and lower sides respectively, and a roughly elliptical long hole is longitudinally penetrated through the upper and lower sides of the above-mentioned ventilation frame 100, and a long hole open frame 115a is formed along the edge of the above-mentioned long hole opening.

[0083] The long hole-shaped opening can reduce direct contact with specific key parts such as the anus, thereby reducing the foreign body sensation or pressure sensation, improving the wearing feel, and achieving smooth ventilation.

[0084] Considering that the user's gluteal groove gradually narrows toward the coccyx, in order to provide a comfortable wearing feeling, the ventilation frame 100 is preferably rounded so that the size of the elliptical frame 110 arranged at the rear end (on the user's coccyx side) gradually becomes smaller.

[0085] Of course, in order to provide a more comfortable wearing feeling, the ventilation frame 100 may be rounded so that the sizes of the elliptical frames 110 disposed at the front and rear ends gradually become smaller.

[0086] Of course, in order to maintain proper elasticity and structure, the distance between the elliptical frame 110 and the linear frame 120 and the number of the elliptical frame 110 and the linear frame 120 can be increased as needed.

[0087] In addition, although not specifically shown in the drawings, in order to reinforce the elliptical frame 110 and the linear frame 120 , the ventilation frame 100 may further include a plurality of elongated reinforcement frames arranged along an oblique direction.

[0088] The ventilation frame 100 is inserted along the gluteal groove (skin) in the length direction to open the gluteal groove. At this time, in order to prevent unpredictable side effects from being caused by stimulating only specific body parts such as the anus, the ventilation frame 100 is inserted from above the anus across the entire gluteal groove (in the case of men, up to the front of the scrotum).

[0089] And, as Figure 13 As shown, a ventilation outer skin 200 may be further included. The ventilation outer skin 200 is made of fiber material and covers the entire exterior of the ventilation frame 100 to prevent the skin, ie, the buttock groove, from directly contacting the ventilation frame 100 .

[0090] The ventilation outer skin 200 may be manufactured separately from the underwear, or may be manufactured in a form fixed to the underwear (by sewing, etc.), so that the ventilation frame 100 may be stably located in the gluteal groove (skin).

[0091] The ventilation outer skin 200 is preferably made of functional fibers that are mainly used in underwear materials for ventilation, and may also be made of pure cotton so that the skin does not feel a foreign body sensation.

[0092] In addition, as another embodiment of the present invention, the ventilation outer skin 200 may further include a separate fixing component (not shown in the figure) attached to the underwear to better maintain the state of being inserted into the gluteal groove together with the ventilation frame 100.

[0093] In addition, as another embodiment of the present invention, connecting components such as connecting rings can be provided at both ends of the ventilation frame 100 for connecting with underwear or the like using a rope or the like.

[0094] In addition, as another embodiment of the present invention, Figure 11 and Figure 12 As shown, the ventilation frame 100 may not form the long hole open frame 115a, but may form a linear opening by cutting the upper and lower portions of the ventilation frame 100 along the entire length direction, and form a linear open frame 116a along the edge of the linear opening.

[0095] At this time, in order to connect the elliptical frames 100 divided by the linear openings to each other, a connecting frame 117 is formed to connect the central parts of the facing divided elliptical frames 100. The connecting frame 117 can be formed on the entire elliptical frame 100, or as shown in the figure, it can be arranged at intervals in a dispersed manner.

[0096] In the case of having such a straight open frame 116a, it is also possible to improve the wearing feel and achieve smooth ventilation by reducing direct contact with specific main parts such as the anus and reducing the foreign body sensation or pressure sensation.

[0097] In this embodiment, considering that the user's gluteal groove gradually narrows toward the coccyx, in order to provide a more comfortable wearing feeling, it is also preferred that the above-mentioned ventilation frame 100 is rounded so that the size of the elliptical frame 110 arranged at the front and rear ends (on the user's coccyx side) gradually becomes smaller.

[0098] Moreover, in this embodiment, a ventilation outer skin 200 may also be included. The ventilation outer skin 200 is made of fiber material and covers the entire exterior of the ventilation frame 100 to prevent the skin, i.e., the buttock groove, from directly contacting the ventilation frame 100 .

[0099] As described above, the skeleton of the hip ventilating device of the present invention is composed of a ventilation frame 100 consisting of an elongated elliptical frame 110 like an umbrella rib and a linear frame 120, which minimizes irritation to specific body parts such as the anus and maximizes ventilation effect.

[0100] Moreover, the whole is covered by a ventilated outer skin 200, and is inserted in a clamping manner along the entire gluteal groove in a gentle arc from just above the anus to the front. It has little foreign body sensation and excellent fixing force, so it can enable obese people, white-collar workers who work for a long time, drivers or people who sweat a lot to live a comfortable life.

[0101] In particular, since soft materials of different properties are arranged in a dispersed manner, it can be deformed freely to the left and right, and the divided frames can be independently moved further to the left, right, front and back. Even if the user's physical conditions are different, it can provide a more comfortable wearing feeling according to the curve of the human body when worn.

[0102] In particular, the ventilation frame 100 is also configured with a long hole opening or a straight line opening, which can reduce contact with sensitive parts such as the anus even if the user's physical conditions are different, maximize the ventilation feeling, and provide a more comfortable wearing feeling according to the human body curve when worn.

[0103] Furthermore, when the ventilation frame is rounded to gradually become thinner toward the coccyx, the problem of exposed lines due to its protrusion to the outside can be solved, making the appearance more slender.

[0104] In other words, by forcibly opening the gluteal groove (skin) including the anus, natural ventilation can be achieved, allowing secretions, sweat, and moisture in the gluteal groove to naturally ventilate and dry. Therefore, it is also expected that anal diseases such as pruritus ani can be prevented and improved.

[0105] The preferred embodiments of the present invention are described above. In addition to the above embodiments, it is obvious to those skilled in the art that the present invention can be implemented in other specific forms without departing from the spirit or scope of the present invention.

[0106] Therefore, the above embodiments should be regarded as illustrative rather than restrictive, and the present invention is not limited to the above description but may be modified within the scope of the appended claims and their equivalents.

[0107] Industrial Applicability

[0108] The buttocks ventilation device of the present invention as described above has the following industrial advantages: it minimizes the local stimulation and pressure applied to specific body parts such as the anus, maximizes the barrier-free ventilation effect, can solve the problem of exposed lines due to its protrusion to the outside, makes the appearance more slender, and has an excellent wearing feel. Since it is inserted in a gentle arc and clamped manner from just above the anus to the front along the entire buttocks groove, there is less foreign body sensation and excellent fixing force, so it can enable obese people and modern people who sit for long periods of time or sweat a lot to live a comfortable life.
