Description

Shoe insoles with acupressure function

[0001] The present invention relates to a shoe insole, and more specifically, to a shoe insole having a structure in which a main insole having a plurality of conical lower pressure protrusions protruding downward and a pressure member having a plurality of conical upper pressure protrusions protruding upward from the upper side of the lower pressure protrusions are laminated, and which provides an acupressure effect while having excellent cushioning performance through the elastic deformation of the lower pressure protrusions and the upper pressure protrusions.

[0002] It is known that the soles of the human feet contain acupoints that affect various parts of the body, and that various diseases can be treated and prevented by properly stimulating these specific areas.

[0003] Taking advantage of this, insoles with multiple acupressure protrusions have been proposed and used in the past, and such insoles are known to be effective not only for acupressure but also for suppressing the generation of moisture caused by surface contact between the sole of the foot and the insole inside the shoe.

[0004] In particular, to maximize this ventilation effect, structures were even proposed that pump external air into the sole and supply it inside the shoe, but this had the problem of high cost.

[0005] Considering these points, a shoe insole combining acupressure and ventilation effects was proposed in Utility Model Publication No. 1992-7619. Upon examination, this invention is an acupressure-type ventilated ceramic shoe insole formed by integrally molding a conventional shoe insole by mixing ceramic powder, while a plurality of acupressure protrusions are formed on the upper surface of the insole, each having a circular groove on the outer periphery of the bottom and a ventilation hole on one side, with a hollow portion formed inside; and on the bottom surface of the insole, an arc-shaped protrusion is formed with an air circulation opening on the outer edge at a position corresponding to the acupressure protrusions. Although this prior registered invention describes obtaining acupressure and ventilation effects through the acupressure protrusions, the aforementioned acupressure protrusions are completely compressed when pressed by foot pressure, resulting in virtually no acupressure effect.

[0006] In addition, the pressure point protrusions were conical in shape, so they could not properly restore themselves after being pressed, which had the disadvantage of not being able to achieve effects beyond expectations.

[0007] To solve these problems, the applicant has developed a shoe insole having a plurality of protrusions formed thereon and holes formed in the protrusions, wherein the lower end of a protrusion made of silicone, having a vertical hole formed in the center, is integrally connected and molded to the insole by a thin connecting part that is positioned upward from the insole and expands downward (see Korean Registered Patent No. 10-0277299).

[0008] However, the aforementioned conventional shoe insoles with acupressure functions implement acupressure performance in a plurality of acupressure protrusions protruding upwards, so if the acupressure protrusions are too hard, pain is induced during walking, and if the elastic deformation performance of the acupressure protrusions is too excessive, there is a problem that acupressure performance cannot be exerted at all.

[0009] The present invention is intended to solve the aforementioned problems, and the objective of the present invention is to provide a shoe insole that provides appropriate pressure from the pressure protrusions while providing sufficient cushioning at the pressure protrusion areas, thereby not causing pain caused by pressure.

[0010] A shoe insole according to the present invention for achieving the above-mentioned purpose may comprise: a main insole including an insole body made of an elastic material and a plurality of lower pressure protrusions formed to protrude downward from the insole body and having a cone shape with a diameter or width decreasing towards the bottom, which are elastically deformed by pressure applied from the top; and a pressure member including a pressure part body made of an elastic material laminated on the top of the insole body and a plurality of upper pressure protrusions formed to protrude upward from the pressure part body at a position corresponding to the lower pressure protrusions and having a cone shape with a diameter or width decreasing towards the top.

[0011] A ventilation hole through which air passes can be formed vertically in the central part of the lower pressure protrusion and the upper pressure protrusion.

[0012] The lower pressure projection may include a lower deformation-inducing portion in the shape of a cone that decreases in diameter or width toward the lower side, and a lower projection portion extending downward in the shape of a cylinder with a constant diameter at the lower end of the lower deformation-inducing portion.

[0013] The upper pressure projection may include an upper deformation-inducing part in the shape of a cone that decreases in diameter or width toward the top, and an upper projection part that extends upward in the shape of a cylinder with a constant diameter at the upper end of the upper deformation-inducing part.

[0014] The above-mentioned pressure member may be laminated at a position corresponding to the arch of the sole of the body within the above-mentioned insole body, and a cover sheet may be laminated on the upper side of the above-mentioned insole body and on the upper part of the pressure member body, and a plurality of cover holes through which the upper pressure protrusion penetrates may be formed in the cover sheet.

[0015] In the above cover sheet, a plurality of cover ventilation holes corresponding to the plurality of lower pressure protrusions may be formed to penetrate vertically.

[0016] The above cover ventilation hole is configured to have a diameter smaller than the diameter of the upper opening of the lower pressure protrusion, so that when the lower pressure protrusion is pressed and deformed, the lower surface of the periphery of the cover ventilation hole can be supported by coming into contact with the lower pressure protrusion.

[0017] A shoe insole according to another embodiment of the present invention may comprise: an insole member including a plurality of lower pressure protrusions formed to protrude downward and having a cone shape with a diameter or width decreasing towards the bottom, which are elastically deformed by pressure applied from the top; and a pressure member including a pressure body made of an elastic material that is laminated and attached to the top of the insole member, and a plurality of upper pressure protrusions formed to protrude upward from the pressure body at a position corresponding to the lower pressure protrusions and having a cone shape with a diameter or width decreasing towards the top.

[0018] Here, the insole member may include an insole body made of an elastic material and a main insole having a plurality of lower pressure protrusions formed on the lower surface of the insole body; a cushion pad made of an elastic resin material laminated on the upper part of the main insole; and a cover sheet laminated on the upper part of the cushion pad.

[0019] A plurality of cushion control holes and a plurality of cover holes may be formed so as to penetrate vertically at positions corresponding to the plurality of upper pressure protrusions and the plurality of lower pressure protrusions in the cushion pad and the cover sheet.

[0020] A ventilation hole through which air passes can be formed vertically in the central part of the lower pressure protrusion and the upper pressure protrusion.

[0021] The lower pressure projection may include a lower deformation-inducing portion in the shape of a cone that decreases in diameter or width toward the lower side, and a lower projection portion extending downward in the shape of a cylinder with a constant diameter at the lower end of the lower deformation-inducing portion.

[0022] The upper pressure projection may include an upper deformation-inducing part in the shape of a cone that decreases in diameter or width toward the top, and an upper projection part that extends upward in the shape of a cylinder with a constant diameter at the upper end of the upper deformation-inducing part.

[0023] The shoe insole of the present invention provides a cushioning sensation to the user during walking by protruding a plurality of lower acupressure protrusions downward rather than upward on the main insole, while simultaneously providing an acupressure effect by applying pressure to the sole of the foot through a plurality of upper acupressure protrusions protruding upward on the acupressure member.

[0024] In particular, the upper and lower pressure protrusions are formed in a symmetrical cone shape and are arranged in an overlapping manner; therefore, when pressure is applied by the upper protrusions, the lower protrusions undergo elastic deformation to provide a cushioning sensation. Consequently, the pressure intensity transmitted to the soles of the feet is not strong but is delivered gently, preventing pain.

[0038] Additionally, terms such as "first," "second," etc., may be used to describe various components, but said components should not be limited by said terms. These terms are used solely for the purpose of distinguishing one component from another. For example, without departing from the scope of the present invention, the first component may be named the second component, and similarly, the second component may be named the first component. Meanwhile, unless otherwise defined, all terms used herein, including technical or scientific terms, have the same meaning as generally understood by those skilled in the art to which the present invention pertains. Terms such as those defined in commonly used dictionaries should be interpreted as having a meaning consistent with their meaning in the context of the relevant technology, and should not be interpreted in an ideal or overly formal sense unless explicitly defined in this application.

[0039] Referring to FIGS. 1 to 4, a shoe insole (100) having a pressure point function according to one embodiment of the present invention comprises a main insole (110) having a plurality of lower pressure point protrusions (112) formed on its lower surface, a pressure point member (120) laminated on the upper surface of the main insole (110) having a plurality of upper pressure point protrusions (122) formed on its upper surface, and a cover sheet (130) laminated on the upper surface of the main insole (110) and the pressure point member (120).

[0040] The main insole (110) comprises an insole body (111) made of an elastic material and a plurality of lower pressure protrusions (112) formed to protrude downward from the insole body (111).

[0041] The above-mentioned insole body (111) may have a shape and size corresponding to the upper surface of the sole of the shoe and may be made of an elastic resin material such as silicone. A plurality of lower pressure protrusions (112) are formed to protrude downward from the insole body (111).

[0042] The lower pressure projection (112) is shaped like a cone, with its diameter or width decreasing towards the bottom, and is elastically deformed by pressure applied from the top. More specifically, the lower pressure projection (112) includes a lower deformation-inducing part (113) shaped like a cone, with its diameter or width decreasing towards the bottom, and a lower projection part (114) extending downward in the shape of a cylinder with a constant diameter at the bottom of the lower deformation-inducing part (113).

[0043] The lower deformation-inducing portion (113) is made to have a thinner thickness than the lower protrusion portion (114) so ​​that it can be easily elastically deformed by a load transmitted from the upper side and then restored. The lower protrusion portion (114) is formed in the shape of a cylinder with a constant diameter, and a ventilation hole (115) can be formed vertically through the center to allow air to pass through.

[0044] The lower pressure protrusions (112) may be formed with different vertical lengths to provide uniform pressure to the entire sole of the user's foot. For example, the lower pressure protrusions (112) corresponding to the arch of the sole may be formed to protrude further downward than other parts. At this time, the vertical height of the lower deformation-inducing part (113) is all the same, but the total protruding length of the lower pressure protrusions (112) can be adjusted by varying the height of the lower protrusion part (114).

[0045] The above pressure member (120) includes a pressure member body (121) made of an elastic material that is laminated on the upper surface of the insole body (111), and a plurality of upper pressure member protrusions (122) formed to protrude upward from the pressure member body (121) at a position corresponding to the lower pressure member protrusion (112).

[0046] The above-mentioned pressure body (121) is made of an elastic resin material such as silicone and may be laminated only on a part of the upper surface of the insole body (111) of the main insole (110) to apply pressure to a specific part of the sole of the foot. For example, a pressure member (120) may be laminated locally at a position corresponding to the arch portion to apply pressure intensively to the arch portion of the sole of the foot.

[0047] The upper pressure projection (122) has a cone shape that is generally identical or similar to the lower pressure projection (112). That is, the upper pressure projection (122) can be formed in a shape symmetrical to the lower pressure projection (112). The upper pressure projection (122) may include an upper deformation-inducing part (123) in the shape of a cone that decreases in diameter or width toward the top, and an upper projection part (124) that extends upward in the shape of a cylinder with a constant diameter at the upper end of the upper deformation-inducing part (123).

[0048] The upper deformation-inducing part (123), like the lower deformation-inducing part (113), is made to have a thinner thickness than the upper protrusion part (124) so ​​that it can be easily elastically deformed by a load transmitted from the upper side and then restored. In addition, the upper protrusion part (124), like the lower protrusion part (114), is formed in the shape of a cylinder with a constant diameter, and a ventilation hole (125) can be formed vertically through the center to allow air to pass through.

[0049] The upper pressure point protrusion (122) may also be formed with a different protruding length in the vertical direction to correspond to the arch portion of the user's foot. That is, the protruding length (height) of the upper protrusion portion (124) of the upper pressure point protrusion (122) may protrude more significantly than the portion corresponding to the foot arch that is positioned on the outside.

[0050] When a ventilation hole (115, 125) is formed vertically through the lower protrusion (114) of the lower pressure projection (112) and the upper protrusion (124) of the upper pressure projection (122), excellent ventilation function can be obtained as air passes through the ventilation hole (115, 125).

[0051] The cover sheet (130) has a shape and size corresponding to the insole body (111) of the main insole (110) and is made of a sheet with a fabric attached to the upper surface of a fabric, leather, synthetic leather, or resin so as to absorb the user's sweat and provide a cushioning effect, and can be bonded to the upper surface of the insole body (111) of the main insole (110) and the upper surface of the acupressure body (121) of the acupressure member (120) by adhesive or ultrasonic welding.

[0052] In the cover sheet (130), a plurality of cover holes (132) are formed through which the upper protrusion (124) of the upper pressure protrusion (122) passes. Additionally, a plurality of cover ventilation holes (131) corresponding to the plurality of lower pressure protrusions (112) may be formed to pass through vertically in the cover sheet (130).

[0053] The above cover ventilation hole (131) can provide a ventilation function through the ventilation hole (115) formed in the lower pressure protrusion (112), and when the lower pressure protrusion (112) is elastically deformed by a load, a portion of it protrudes upward through the cover ventilation hole (131), thereby providing a pressure point effect that applies weak pressure to the sole of the foot.

[0054] The diameter of the cover ventilation hole (131) may be formed to be generally the same as the diameter of the upper opening of the lower pressure protrusion (112), but as shown in FIG. 5, the diameter of the cover ventilation hole (131) may be smaller than the diameter of the upper opening of the lower pressure protrusion (112). In this case, when the lower pressure protrusion (112) is pressed and deformed, the lower surface of the periphery of the cover ventilation hole (131) comes into contact with the lower pressure protrusion (112) and is supported, so there is an advantage that the cushioning sensation can be further improved.

[0055] The shoe insole of the present invention as described above has a plurality of lower pressure protrusions (112) protruding downward rather than upward on the main insole (110) to provide a cushioning sensation to the user during walking, and at the same time, a plurality of upper pressure protrusions (122) protruding upward on the pressure member (120) apply pressure to the sole of the foot to provide a pressure effect.

[0056] In particular, since the upper pressure protrusion (122) and the lower pressure protrusion (112) are arranged to overlap each other vertically in a symmetrical manner, when pressure is applied by the upper pressure protrusion (122), the lower pressure protrusion (112) undergoes elastic deformation to provide a cushioning sensation, so the pressure intensity transmitted to the sole of the foot is not strong but can be transmitted gently, thus preventing pain.

[0057] Although the central axis of the lower pressure projection (112) and the central axis of the upper pressure projection (122) may generally coincide, as shown in FIG. 6, when the pressure member (120) is laminated onto the upper surface of the insole body (111) of the main insole (110) and bonded with a cover sheet (130), the central axis of the lower pressure projection (112) and the central axis of the upper pressure projection (122) may be attached at a certain distance eccentrically. Even when the central axis of the lower pressure projection (112) and the central axis of the upper pressure projection (122) are attached at a certain distance eccentrically, the lower projection part (114) of the lower pressure projection (112) presses the upper deformation-inducing part (123) or the upper projection part (124) of the upper pressure projection (122), thereby providing both cushioning and pressure force simultaneously.

[0058] FIGS. 7 to 9 show another embodiment of a shoe insole according to the present invention. The shoe insole of this embodiment differs from the shoe insole of the first embodiment in that a cushion pad (140) for controlling the elasticity of the upper pressure protrusion (122) of the pressure member (120) and the lower pressure protrusion (112) of the main insole (110) is laminated on the upper surface of the main insole (110).

[0059] The cushion pad (140) may have an insole shape and size that generally matches the insole body (111) of the main insole (110), and may be made of an elastic resin material. The cushion pad (140) may be manufactured separately from the main insole (110) and then laminated by being bonded to the upper surface of the insole body (111) of the main insole (110) by an adhesive or ultrasonic welding.

[0060] Additionally, a plurality of cushion control holes (141) for adjusting the elasticity of the upper pressure protrusions (122) may be formed vertically through the cushion pad (140) at positions corresponding to the plurality of upper pressure protrusions (122) of the pressure member (120) and the plurality of lower pressure protrusions (112) of the main insole (110). As shown in FIG. 8a, the diameter of the cushion control holes (141) may be formed to be smaller than the lower opening of the upper pressure protrusions (122) or the upper opening of the lower pressure protrusions (112), but as shown in FIG. 9a, the diameter of the cushion control holes (141) may be equal to or slightly larger than the lower opening of the upper pressure protrusions (122) or the upper opening of the lower pressure protrusions (112).

[0061] As illustrated in FIG. 8b, if the diameter of the cushion control hole (141) is smaller than the lower opening of the upper pressure projection (122) or the upper opening of the lower pressure projection (112), when the upper pressure projection (122) and the lower pressure projection (112) are pressed and deformed, a portion of the upper pressure projection (122) and the lower pressure projection (112) is supported by the periphery of the cushion control hole (141), so that the support force is relatively large and strong pressure force can be provided. On the other hand, as illustrated in FIG. 9b, if the diameter of the cushion control hole (141) matches the lower opening of the upper pressure projection (122) or the upper opening of the lower pressure projection (112), or is slightly larger than that, when the upper pressure projection (122) and the lower pressure projection (112) are pressed and deformed, a portion of the upper pressure projection (122) and the lower pressure projection (112) is inserted into the cushion control hole (141), so the support force is relatively small, and a soft pressure force can be provided.

[0062] In this way, the cushion pad (140) can adjust the pressure of the upper pressure projection (122) and the lower pressure projection (112) through the diameter of the cushion control hole (141).

[0063] Additionally, the cushion pad (140) can provide elastic support of various sizes depending on its thickness and material. For example, even if made of the same material, if the thickness of the cushion pad (140) increases, a greater elastic force is applied, so the pressure force of the upper pressure protrusion (122) and the lower pressure protrusion (112) increases, and if the thickness of the cushion pad (140) decreases, a smaller elastic force is applied, so the pressure force of the upper pressure protrusion (122) and the lower pressure protrusion (112) decreases.

[0064] FIGS. 10 to 12 are drawings showing another embodiment of a shoe insole according to the present invention.

[0065] The shoe insole of this embodiment comprises a main insole (110) as an insole member, a cushion pad (140) made of an elastic resin material laminated on the upper part of the main insole (110), and a cover sheet (130) laminated on the upper part of the cushion pad (140), and is configured such that a pressure member (120) having a plurality of upper pressure protrusions (122) is laminated and attached to the upper surface of the cover sheet (130) which constitutes the uppermost surface of the insole member.

[0066] That is, unlike the shoe insole embodiments shown in FIGS. 7 to 9, the shoe insole of this embodiment is structured such that the pressure member (120) is not installed on the lower side of the cover sheet (130) but is installed on the upper side of the cover sheet (130).

[0067] Similar to the embodiments described above, the main insole (110) comprises an insole body (111) made of an elastic material such as silicone, and a plurality of lower pressure protrusions (112) formed to protrude downward from the insole body (111).

[0068] Additionally, the pressure member (120) includes a pressure member body (121) made of an elastic material that is laminated and attached to the upper surface of the cover sheet (130), and a plurality of upper pressure member protrusions (122) formed to protrude upward from the pressure member body (121) at a position corresponding to the lower pressure member protrusion (112).

[0069] The shape and function of the lower pressure protrusion (112) and the upper pressure protrusion (122) may be identical or similar to the shape and function of the lower pressure protrusion (112) and the upper pressure protrusion (122) of the previously described embodiments, so a detailed description thereof is omitted.

[0070] The cushion pad (140) may have an insole shape and size that generally matches or is slightly larger than the insole body (111) of the main insole (110), similar to the cushion pad (140) of the above-described embodiment, and may be made of an elastic resin material. The cushion pad (140) may be manufactured as a separate unit from the main insole (110) and then laminated by being bonded to the upper surface of the insole body (111) of the main insole (110) by an adhesive or ultrasonic welding.

[0071] Additionally, a plurality of cushion control holes (141) for adjusting the elasticity of the upper pressure protrusions (122) may be formed vertically through the cushion pad (140) at positions corresponding to the plurality of upper pressure protrusions (122) of the pressure member (120) and the plurality of lower pressure protrusions (112) of the main insole (110). As shown in FIG. 12, the diameter of the cushion control holes (141) may be formed to be smaller than the lower opening of the upper pressure protrusions (122) or the upper opening of the lower pressure protrusions (112).

[0072] In this way, when the diameter of the cushion control hole (141) is smaller than the lower opening of the upper pressure projection (122) or the upper opening of the lower pressure projection (112), when the upper pressure projection (122) and the lower pressure projection (112) are pressed and deformed, a portion of the upper pressure projection (122) and the lower pressure projection (112) is supported by the periphery of the cushion control hole (141), so that the support force is relatively large and strong pressure force can be provided.

[0073] On the other hand, if the diameter of the cushion control hole (141) matches the lower opening of the upper pressure projection (122) or the upper opening of the lower pressure projection (112), or is slightly larger than that, when the upper pressure projection (122) and the lower pressure projection (112) are pressed and deformed, a part of the upper pressure projection (122) and the lower pressure projection (112) is inserted into the cushion control hole (141), so the support force is relatively small, and a soft pressure force can be provided.

[0074] In this way, the cushion pad (140) can adjust the pressure of the upper pressure projection (122) and the lower pressure projection (112) through the diameter of the cushion control hole (141).

[0075] The above cover sheet (130) is laminated on the upper surface of the cushion pad (140). The cover sheet (130) also has a shape and size corresponding to the insole body (111) of the main insole (110), similar to the cover sheet (130) of the above-described embodiment, and is made of a sheet in which a fabric is attached to the upper surface of a fabric, leather, synthetic leather, or resin so as to absorb the user's sweat and provide a cushioning sensation, and can be bonded to the upper surface of the insole body (111) of the main insole (110) and the upper surface of the acupressure body (121) of the acupressure member (120) by adhesive or ultrasonic welding.

[0076] In the cover sheet (130), a plurality of cover holes (132) corresponding to the upper pressure protrusion (122) and the lower pressure protrusion (112) are formed to penetrate vertically. The cover holes (132) can provide a pressure effect that weakly presses the sole of the foot by ensuring ventilation through the ventilation holes (125) of the upper pressure protrusion (122) and the ventilation holes (115) of the lower pressure protrusion (112), and by allowing a portion of the upper pressure protrusion (122) to protrude downward through the cover holes (132) when the upper pressure protrusion (122) is elastically deformed by a load.

[0077] In addition, a plurality of cover ventilation holes (131) corresponding to the plurality of lower pressure protrusions (112) may be formed in the cover sheet (130) to penetrate vertically.

[0078] The above cover ventilation hole (131) can provide a ventilation function through the ventilation hole (115) formed in the lower pressure protrusion (112), and when the lower pressure protrusion (112) is elastically deformed by a load, a portion of it protrudes upward through the cover ventilation hole (131), thereby providing a pressure point effect that applies weak pressure to the sole of the foot.

[0079] The diameter of the cover ventilation hole (131) may be formed to be generally the same as the diameter of the upper opening of the lower pressure protrusion (112), but the diameter of the cover ventilation hole (131) may be smaller than the diameter of the upper opening of the lower pressure protrusion (112). In this case, when the lower pressure protrusion (112) is pressed and deformed, the lower surface of the periphery of the cover ventilation hole (131) comes into contact with the lower pressure protrusion (112) and is supported, so there is an advantage that the cushioning sensation can be further improved.

[0080] Although the detailed description of the present invention described above has been explained with reference to preferred embodiments of the invention, those skilled in the art or those with ordinary knowledge in the art will understand that various modifications and changes can be made to the invention without departing from the spirit and technical scope of the invention as set forth in the claims below.
