Description

  The present invention relates to a human body abutting tool, and more particularly to an instrument that abuts against the surface of a human body and relieves pressure on the human body, such as a cushion or a backrest.

  In recent years, when sitting in a chair or wheelchair, blood circulation in the vicinity of the knees worsens, and it is thought that it causes blood clots as in economy class syndrome. Therefore, if the vicinity of the knee is slightly lifted, blood circulation near the knee is improved and thrombus formation can be prevented.

  In addition, when the area around the knee is lifted slightly, the person sitting from the chair or the wheelchair is less likely to slide down, the sitting comfort is improved, the posture is improved, and the blood circulation of the sitting person is improved.

  Especially for people with diapers, such as elderly people, injured persons, or non-healthy persons (disabled persons), when sitting on a wheelchair or chair, the position of the buttocks relative to the position of the back of the knee corresponds to the thickness of the diaper. As it was only high, elderly persons, injured persons, or disabled persons were able to slip easily from wheelchairs and chairs.

  On the other hand, as a human body contact tool, there has conventionally been a device in which an elongated rod-shaped pressure receiving body is installed in the vicinity of the back of the knee of a chair. There were also cushions that gradually became thicker from the hips to the back of the knees.

  However, in the case of an elongated rod-shaped pressure receiving body, a step of the pressure-receiving body hits a portion from the collar portion of the rod-shaped pressure receiving body, and on the contrary, the pressure is very strong with the step being the boundary. A weak and floating part was next to each other, causing discomfort. In addition, in the cushion that gradually thickened from the hip to the back of the knee, the cushion was in close contact from the knee to the hip, resulting in poor air permeability and also causing discomfort.

  The present invention has been made in order to solve the above-described problems, and an object of the present invention is to provide a human body contact tool that can provide a comfortable contact feeling from the back of the knee to the buttocks or from the waist to the buttocks. Is to provide.

  In order to achieve the above object, the present invention comprises a first pressure receiving body which is recessed by pressing and receives pressure, and is installed near the back of a human knee, and a thickness smaller or higher than the first pressure receiving body. A second pressure-receiving body that is recessed by pressure and receives pressure and is placed closer to the human buttocks than the first pressure-receiving body, and the thickness or height of the second pressure-receiving body is smaller than that of the second pressure-receiving body. A third pressure receiving body that is low, recessed by pressure and receives pressure, and is located closer to the human buttocks than the second pressure receiving body, and connects the first pressure receiving body and the second pressure receiving body. And connecting the first pressure receiving body and the first connecting body having a thickness smaller or lower than the second pressure receiving body, the second pressure receiving body and the third pressure receiving body, The thickness is smaller than those of the second pressure receiving body and the third pressure receiving body. Height and a lower second coupling body.

  From the first pressure-receiving body to the second pressure-receiving body, the thickness gradually becomes smaller or the height becomes lower, so there is no step and comfortable contact from the back of the knee to the buttocks or from the waist to the buttocks A feeling or sitting comfort is obtained.

  In addition, since the connecting body between the pressure receiving bodies is smaller in thickness or lower in height than the pressure receiving body, a gap is formed in the connecting body, and the human body contact tool extends from the back of the knee to the buttocks or from the waist to the buttocks. Does not adhere to each other, improves air permeability, and provides a comfortable contact feeling or sitting comfort.

  Even if an elderly person sits wearing a diaper, the knees are raised so that they will not fall off. Even if a person who is not wearing a diaper sits, the knees are lifted and the back is not bent forward, and the posture is correct and beautiful.

  Since each connecting body is smaller in thickness or lower in height than each pressure receiving body, it is easy to fold the human body contact tool. Also, since the locking body is locked to the back of the chair or wheelchair or abuts against the back of the lower leg, this locking body can be pulled to lift or change the position of the elderly / non-healthy person. Or move it.

The connecting portion 18 and the peripheral suture portion 10 are parallel to each other. These two stitching lines are the first lower stitching portion 31 and the second lower stitching portion 32 from the left side.

  A portion between the lower middle cloth 3 and the lower cloth 4 and sealed by the connecting portion 18, the first lower stitching portion 31, and the peripheral stitching portion 10 becomes a first lower pressure receiving body 36. A portion between the lower middle cloth 3 and the lower cloth 4 and sealed by the first lower stitching portion 31, the second lower stitching portion 32, and the peripheral stitching portion 10 becomes a second lower pressure receiving body 37. A portion between the lower middle cloth 3 and the lower cloth 4 and sealed by the second lower stitching portion 32 and the peripheral stitching portion 10 becomes a third lower pressure receiving body 38.

  The first lower pressure receiving body 36, the second lower pressure receiving body 37, and the third lower pressure receiving body 38 are all sealed by sealing their peripheral edges, and a large number of round tubes 21 and cylindrical tubes 22 are incorporated inside. Yes. Thereby, the round tube 21 and the cylindrical tube 22 can also be arrange | positioned under the 1st connection part 5, the 2nd connection part 6, the 3rd connection part 7, the 4th connection part 8, and the 5th connection part 9. FIG.

  The first lower pressure body 36, the second lower pressure body 37, and the third lower pressure body 38 are the first pressure body 11, the second pressure body 12, the third pressure body 13, the fourth pressure body 14, The thickness is smaller, the thickness is thinner, or the height is lower than that of the fifth pressure receiving body 15 and / or the sixth pressure receiving body 16.

  A plurality of the fourth pressure receiving body 14, the fifth pressure receiving body 15 and / or the sixth pressure receiving body 16 and the third connecting portion 7, the fourth connecting portion 8 and / or the fifth connecting portion 9 are alternately connected, It reaches the buttocks from the back of the person's knees or waist and is in contact with the vicinity of the buttocks. Thereby, a body contact tool does not stick to a buttocks, air permeability improves, and a comfortable contact feeling or sitting comfort is obtained.

  The upper pressure cloth 1, upper middle cloth 2, lower middle cloth 3 and lower cloth 4 have their first pressure-receiving body 11 and the portion on the left side of the connecting portion 18 sewn together at the periphery without any intervening therebetween. The locking sheet 39 is formed, and the locking sheet 39 is connected to the first pressure receiving body 11. The lower cloth 4 is formed by laminating a plurality of sheets or one piece of cloth and quilting them, and is integrated and washable so as not to deviate from each other.

  Strings 40, 40 (fixing means, connecting means) are connected to both ends of the locking sheet 39. The strings 40, 40 are tied to a wheelchair or a chair column so that the human body abutting tool does not fall off the chair or the wheelchair.

(2) Usage State of Human Body Contact Tool FIGS. 3 and 4 show the usage state of the human body contact tool. The first pressure receiving body 11, the second pressure receiving body 12, the third pressure receiving body 13, the fourth pressure receiving body 14, the fifth pressure receiving body 15, and the sixth pressure receiving body 16 include a round tube 21 and a cylindrical tube 22. Therefore, when the buttocks, thighs, and knees are placed on the human body abutting tool, or when the buttocks abut from the waist, the first pressure receiving body 11, The second pressure receiving body 12, the third pressure receiving body 13, the fourth pressure receiving body 14, the fifth pressure receiving body 15, and the sixth pressure receiving body 16 are recessed to receive the pressure.

  The first pressure receiving body 11, the second pressure receiving body 12, the third pressure receiving body 13, and the fourth pressure receiving body 14 are sequentially narrowed in this order, and the fourth pressure receiving body 14 and the fifth pressure receiving body 15. The sixth pressure receiving body 16 has the same width.

  Further, the first pressure receiving body 11, the second pressure receiving body 12, the third pressure receiving body 13, and the fourth pressure receiving body 14 are filled with the round tube 21 and the cylindrical tube 22 in this order less, The fourth pressure receiving body 14, the fifth pressure receiving body 15, and the sixth pressure receiving body 16 are filled with the same amount of the round tube 21 and the cylindrical tube 22.

  Therefore, in the order of the first pressure receiving body 11, the second pressure receiving body 12, the third pressure receiving body 13, and the fourth pressure receiving body 14, the thickness is reduced, the thickness is decreased, or the height is decreased, and the inclination is inclined. The fourth pressure receiving body 14, the fifth pressure receiving body 15, and the sixth pressure receiving body 16 have the same thickness, the same thickness, or the same height, and are not inclined.

  As shown in FIG. 3, the first pressure receiving body 11 is arranged / installed near the back of a human knee, and the second pressure receiving body 12, the third pressure receiving body 13, the fourth pressure receiving body 14, and the fifth pressure receiving body. 15. The sixth pressure receiving body 16 is sequentially arranged / installed in this order from the back of the knee toward the buttocks.

  That is, the thigh is in contact with the inclined portions of the first pressure receiving body 11, the second pressure receiving body 12, the third pressure receiving body 13, and the fourth pressure receiving body 14, and the fourth pressure receiving body 14, the fifth pressure receiving body 15, and the fourth pressure receiving body 15. The flange portion contacts the non-inclined portion of the six pressure receiving bodies 16. In other words, the front (left) from the center of the human body contact tool is inclined, and the rear (right) from the center is not inclined.

  Thereby, it is possible to prevent the diaper part from being inclined and the buttocks not to be inclined for a person having a diaper, such as an elderly person, an injured person, or a disabled person, thereby achieving a comfortable sitting comfort. If it is tilted to the buttocks, it will not be stable when sitting, and the sitting comfort will worsen.

  Further, for a person who has a diaper, such as an elderly person, an injured person, or a disabled person, even if the thickness of the diaper increases, the wheelchair or chair does not easily slip. Furthermore, when sitting on a wheelchair or chair, the position of the back of the knee is higher than the position of the buttocks, the sitting comfort is improved, the posture is improved, and the blood circulation of the sitting person is improved.

  In addition, the thickness gradually decreases from the first pressure receiving body 11 to the second pressure receiving body 12, the third pressure receiving body 13, the fourth pressure receiving body 14, the fifth pressure receiving body 15, and the sixth pressure receiving body 16. Since the thickness is reduced or the height is lowered, there is no level difference, and a comfortable contact feeling or sitting comfort can be obtained from the back of the knee to the buttocks.

  Moreover, since the connection parts 5-9 between each pressure receiving bodies 11-16 are thinner than the pressure receiving bodies 11-16, thickness is thin, or height is low, a clearance gap is made in these connection parts 5-9. From the back of the knee, through the thighs to the buttocks, the human body contact tool does not adhere, the air permeability is improved, and a comfortable contact feeling or sitting comfort is obtained.

  The first lower pressure body 36, the second lower pressure body 37, and the third lower pressure body 38 have the same shape and size, but the first lower pressure body 36, the second lower pressure body 37, and the third lower pressure body 38. In this order, the round tube 21 and the cylindrical tube 22 are sequentially filled with a small amount. Therefore, since it inclines from the back of the knee through the thigh to the buttocks in the same manner as described above, the same effects as described above are obtained.

  The locking sheet 39 is in front of the first pressure receiving body 11 (left), and the first pressure receiving body 11 abuts against the back of the knee. The thigh feel can be improved.

  Since the pair of protrusions 27 are located on the outer sides of both knees, both knees are prevented from spreading outwards and hitting a wheelchair column, and the sitting comfort is improved. In particular, when the outsides of the backs of both knees are slightly lifted by the pair of protrusions 27, the sitting person does not slip down, and the sitting comfort is improved. Moreover, since it contacts the outer side of the back of the knee of the human body, a comfortable contact feeling or sitting comfort of the knee can be obtained.

  As shown in FIG. 4, the human body contact tool is installed and contacted from the waist of the human body to the buttocks. The first pressure receiving body 11, the second pressure receiving body 12, and the third pressure receiving body 13 are installed near the waist, and the third pressure receiving body 13, the fourth pressure receiving body 14, the fifth pressure receiving body 15, and the sixth pressure receiving body 16 are Installed near the buttocks.

  In addition, the thickness gradually decreases from the first pressure receiving body 11 to the second pressure receiving body 12, the third pressure receiving body 13, the fourth pressure receiving body 14, the fifth pressure receiving body 15, and the sixth pressure receiving body 16. Since the thickness is reduced or the height is lowered, there is no level difference, and a comfortable contact feeling or sitting comfort can be obtained from the waist to the buttocks.

  Moreover, since the connection parts 5-9 between each pressure receiving bodies 11-16 are thinner than the pressure receiving bodies 11-16, thickness is thin, or height is low, a clearance gap is made in these connection parts 5-9. From the waist to the buttocks, the human body contact tool does not adhere, the air permeability is improved, and a comfortable contact feeling or sitting comfort is obtained.

  The locking sheet 39 can be folded and hooked on the back of a chair or a wheelchair. Accordingly, the human body abutting tool can be kept in contact from the waist to the buttocks so as not to slide off from the backrest.

  Since the pair of protrusions 27 are located on the outer side of the waist, the waist is prevented from hitting the support columns on both sides of the backrest. Further, the protrusion 27 and the first pressure receiving body 11 allow the human body abutment tool to abut so as to surround the waist, and a comfortable abutment or sitting comfort of the waist can be obtained.

  Moreover, depending on the case, the human body contact tool can be turned over and laid under the buttocks from the back of the knee, through the thighs, or from the waist to the buttocks. Accordingly, the first lower pressure receiving body 36, the second lower pressure receiving body 37, and the third lower pressure receiving body 38 can provide the same comfortable contact feeling or sitting comfort as described above.

(3) Material / Effect of Human Body Contacting Tool For the upper cloth 1, upper middle cloth 2, lower middle cloth 3 and / or side edge cloth 26, for example, a “shine up” material having a photocatalytic function is used. The round tube 21 (or the cylindrical tube 22) is made of a material having a photocatalytic function on the entire surface or a “shine up” material.

  The upper inner cloth 2, lower inner cloth 3, lower cloth 4 and / or side edge cloth 26 emit far infrared rays, for example, "Lonwave" (Kuraray Co., Ltd., registered trademark) or "Serum A" (Toyobo Co., Ltd.) Company products, registered trademarks) or “Epicomodo” ”(registered trademark),“ wool zeolite ”or“ binest sera ”(registered trademark) are used.

  In the above “shine up”, a metal-containing ceramic-based special deodorant is kneaded into a composite fiber composed of polyester fiber and nylon fiber, and the deodorization and antibacterial effects are exhibited by the photocatalytic reaction of titanium dioxide. The same is true for cloths sold by Shinshu Ceramics Co., Ltd.

  Other materials having a photocatalytic function such as the round tube 21 or the cylindrical tube 22 are coated with titanium dioxide, CdS, CdSe, WO3, Fe2O3, SrTiO3, or KNbO on the surface of the tube resin such as apatite. , Shine-up (fiber, cloth, cotton), dismel (product of Toyobo Co., Ltd.), epicomodo, etc., rounded or cylindrical, etc. are selected.

  The above “Lonwave”, “Serum A” or “Epicomodo” has an ultrafine particle ceramic incorporated / kneaded in an acrylic fiber or other fiber. By the action of this ceramic, far infrared rays are radiated to the outside at around 40 degrees Celsius near the body temperature, and a heating effect on the human body is exhibited. Around 40 degrees Celsius, far infrared rays are generated most.

  The far-infrared wavelengths emitted by the “Longwave”, “Serum A” or “Epicomodo” are almost all over 5.0 μm or more, and the far-infrared wavelengths emitted by the zeolite are around 1.5 to 6.0 μm. The number of far-infrared wavelengths emitted by “Longwave” is very high in the vicinity of 8 to 16 μm.

  The “wool zeolite” or “binest sera” is obtained by firmly attaching ceramics obtained by processing zeolite, which is a natural ore, and fine particles thereof to the surface of natural fibers such as wool. By the action of the ceramics and the fine particles, far infrared rays are sufficiently emitted to the outside even at a temperature lower than the body temperature, and the effect of heating the human body is exhibited.

  Since the chemical composition of the zeolite is a condensed salt in which a part of silicon in the silicate is replaced with aluminum, and is based on a three-dimensional network structure in the SiO4-AlO4 connecting tetrahedron, a structure including a cavity is formed, Cations (cations) and water of crystallization are present in the cavities or pores formed by connecting the cavities in correspondence with the anions (anions), and water of crystallization due to electrostatic attraction of metal ions.

  There are zeolites of various structures depending on the ratio of silicon to aluminum in the framework, or the type and number of cations. General properties of zeolite include cation exchange capacity, molecular fluid action, polar substance adsorption, and catalysis.

  Since the crystal water of zeolite exists as water molecules in the three-dimensional network structure of zeolite, it is called zeolite water. Even if dehydrated by heating, the structure of the zeolite is not destroyed, and the portion where crystal water is present is left as it is. It remains as a cavity and has a sponge-like structure. This cavity has a property of strongly adsorbing gas and moisture.

  Another major characteristic of zeolite is its base substitution capacity. This is also called cation exchange capacity “CEC Exchange Capacity”, and is a force that holds and separates cations (NH4 +, potassium, sodium, calcium, etc.) just like a magnet. In particular, the base substitution capacity of zeolite is called permanent charge, and has the property of maintaining its force for a long period of time without being influenced by the surrounding environment (PH, etc.).

  Thus, zeolite has an adsorption function. In a cloth using such an adsorbing material and an optical semiconductor ceramic, bacteria, viruses, molds, malodorous substances, harmful substances, etc. are first adsorbed and held on the adsorbing material, and have an antibacterial deodorizing function.

  Thereafter or simultaneously, bacteria, viruses, fungi and the like are killed or reduced by the photocatalytic action of the photo-semiconductor powder and the metal powder which have been irradiated with light, and malodorous substances and the like are decomposed. Furthermore, even in the case of bacteria and other things that are not adsorbed, growth (growth) prevention, repellent effect and the like can be obtained by photocatalytic action. Zeolite emits far-infrared rays almost uniformly at all temperatures from 0 to 60 degrees.

  The infrared rays emitted from the “wool zeolite” or “Bionest Sera” are mid-infrared rays, and the infrared rays emitted from the “Longwave”, “Serum A” or “Epicomodo” are far infrared rays and super far infrared rays. As for infrared rays, wavelengths of 0.76 to 1.5 μm are referred to as near infrared rays, wavelengths of 1.5 to 5.6 μm are referred to as mid-infrared rays, wavelengths of 5.6 to 400 μm are referred to as far infrared rays, and wavelengths of 400 to 1000 μm are referred to as ultra far infrared rays. However, in the present specification and claims, the far infrared ray including the mid infrared ray will be described as the far infrared ray, and the super far infrared ray will be described as the far infrared ray.

  The longer the far-infrared wavelength, the deeper the human tissue penetrates and warms it from the deeper part. Therefore, the longer the far-infrared wavelength, the longer it takes for the far-red effect to appear.Once the far-red effect is achieved, the sustainability lasts longer. continue.

  In addition, the shorter the far-infrared wavelength, the warmer the surface of the human tissue is. Therefore, the shorter the wavelength of the far-infrared, the faster the far-red effect appears immediately, and there is immediate effect, and warms up (warms up) immediately after putting the foot on the foot protector.

  Therefore, “Bio Nest Cera” and “Wool Zeolite” of the above-mentioned batting 12 have an immediate effect / surface effect, and “Long Wave”, “Serum A” and “Epicomodo” of the above-mentioned surface cloth 11 have a slow effect / deep effect. It can be said that there is. The surface cloth 11 and the batting 12 may be a mixture of the above-mentioned “wool zeolite”, “Bionest Cera”, “Ronwave”, “Serum A” or “Epicomodo”.

  In particular, since the arteries are located deep inside the human body, the long-wavelength far infrared rays promote blood circulation and lymph flow, and the veins and lymph vessels are located in the shallow inside the human body. Promotes lymph flow. In this way, the carotid artery, the jugular vein, and the lymphatic vessel can be shared by the difference in the wavelength of far-infrared rays to achieve blood circulation promotion and lymph flow promotion.

  Thus, when far-infrared rays are emitted from the lower cloth 4 or the like and the photocatalytic function is exhibited by the upper cloth 1, the round tube 21... Or the cylindrical tube 22. However, dirt, germs, odors, dirt, and waste products accompanying or due to sweating can be decomposed by photocatalysis. Moreover, the function of the photocatalyst can be enhanced by the far infrared rays, and the antibacterial and deodorizing effects can be synergistically enhanced.

The cylindrical tube 22 is, for example, 4 to 15 mm in length, preferably 6 to 10 mm,
The outer diameter is 3 to 10 mm, preferably 4 to 5 mm, the thickness is 0.01 to 1 mm, preferably 0.05 to 0.1 mm, and the material is made of synthetic resin (plastic) such as polyethylene, polypropylene, and acrylic. Yes.

  The round tube 21 has an outer diameter of 3 to 20 mm, preferably 5 to 10 mm, a thickness of 0.01 to 1 mm, preferably 0.05 to 0.1 mm, and is made of polyethylene, polypropylene, acrylic, etc. It is made of synthetic resin (plastic) and is relatively hard but flexible. The hardness may be harder or softer than the cylindrical tube 22.

  Since the cylindrical tubes 22 are cylindrical, through holes are formed, and further, the round tubes 21 are also formed with through holes. The size of the through holes of the round tubes 21 is 20% to 50% of the outer diameter of the round tubes 21, and is 0.6 to 10 mm, preferably 1 to 5 mm. Further, the size of the through hole of the cylindrical tubes 22 is 2 to 9.99 mm, preferably 3 to 4.99 mm.

  Moreover, the size of the through hole of the round tube 21 is smaller than the outer diameter / size / thickness of the cylindrical tube 22 ..., and the outer diameter / size of the round tube 21 ... is set to the cylindrical tube 22 ... It is selected to be larger than the size of the through hole. Therefore, the cylindrical tubes 22 do not enter the through holes of the round tubes 21. Conversely, the round tubes 21 do not enter the through holes of the cylindrical tubes 22. Therefore, even if the limb improving device is used for a long time, the round tubes 21 and the tubular tubes 22 can be used comfortably for a long time without decreasing the overall volume.

  In addition, the granular material accommodated in this limb improvement tool is good also as only the round tube 21 .... In that case, the particulate matter is less likely to enter. However, since the cylindrical tubes 22 are cylindrical, they are excellent in breathability / heat dissipation / drying properties. Therefore, it is good to mix both. The mixing ratio of the two is 10% to 90%: 90% to 10%, preferably 50%: 50% by weight.

  Some or all of the round tubes 21 and / or the cylindrical tubes 22 have a shape memory function. As a result, even if they are deformed by the weight of the limb using the present limb improvement tool, if they are released from the weight of the limb, it will return to its original shape, and will be antibacterial / deodorant such as photocatalytic action described later. / Warming action / blood circulation promoting action such as decomposition action, far infrared ray generation action, etc. does not decrease.

  Some or all of the surfaces of the round tube 21... And / or the tubular tube 22... And the upper cloth 1 have antibacterial action / deodorant action / insect control action / decomposition action such as photocatalytic action by photocatalyst coating. Some or all of the lower cloth 4 and the like have a warming action / blood circulation promoting action such as a far infrared ray generating action.

  Thereby, while the warming action / blood circulation promotion is performed with respect to the human body with far-infrared rays, it is possible to prevent the occurrence of dirt / odor by sweating due to the warming action / blood circulation promotion by the photocatalytic action. Moreover, this far infrared ray is also a kind of light, can enhance the function of the photocatalyst, and can synergistically enhance the antibacterial and deodorizing effects. In particular, when the far-infrared wavelength is close to visible light, and the short-wavelength near-infrared and mid-infrared are used, this effect is further enhanced. The mid-infrared rays are emitted from the above-mentioned batting 12 (wool zeolite).

  It should be noted that a heating action / blood circulation promoting action such as a far-infrared ray generating action on a part or all of the round tube 21... And / or the tubular tube 22, the upper cloth 1, the middle upper cloth 2, and the middle lower cloth 3. In addition, some or all of the lower cloth 4 and the like may have antibacterial action / deodorant action / insect control action / decomposition action such as a photocatalytic action.
