Description

  The present invention relates to a gel cushion used for a bed or the like.

  In addition to the function of supporting and holding a human weight, a cushion used for a bed or the like is required to have good sleeping comfort. A cushion that is comfortable to sleep is required to have moderate softness and compressibility, vibration absorption, dehumidification, deformation follow-up and no sag. Conventionally, a cotton or synthetic fiber web, a synthetic resin foam such as polyurethane foam, a coiled spring body, or the like has been used alone or in combination.

In addition, some cushions used for beds, etc., use sponge rubber, semi-rigid materials and gel-like substances as they are, or are arranged in a columnar shape, and furthermore, partition walls made of these substances are latticed. Products that are arranged side by side have been developed.
Japanese Utility Model Publication No. 52-15307 Japanese Patent Publication No. 2001-514911

  However, in the lattice-like cushion in which the column shape and the partition wall are made of sponge rubber, the cushioning property is given by the compressibility of the sponge rubber of the partition wall, so that a feeling of bottoming is likely to occur. In the lattice cushion with the partition walls made of a semi-rigid material, cushioning is provided by tilting the partition walls to the side of the semi-rigid material. Has the problem of being inferior. Furthermore, both of them are in a state where it is difficult to absorb the twist (shearing force) generated at the time of turning over, and a large muscle exercise is required for turning over, so that it is easy to cause sleep. In the lattice-like cushion in which the partition wall is made of a gel-like substance, the cushioning property is good because the gel-like substance of the partition wall has a cushioning property due to the flexibility and buckling property. In other words, it has a problem of lack of durability, such as so-called fast wear.

  The present invention solves the above problems and has high durability, follows even a small load, absorbs torsion (shearing force) when turning over, and does not sink and feels bottoming. It aims at providing the gel-like cushion used for a bed etc.

  According to the first aspect of the present invention, a gel-like lattice body having a plurality of polygonal aggregates is formed by continuous lattice walls made of a gel-like resin to form a gel-like lattice body having at least an open top. The upper layer portion and the lower layer portion of the lattice-like lattice body are set to have different compressibility, bendability and buckling property, and the lower layer portion is within the polygonal shape of the honeycomb-shaped structure constituting the gel-like lattice body. In addition, both ends of a rib made of gel resin having a plane shape lower than the height of the lattice wall from the bottom thereof are integrally formed on the inner wall of the lattice wall.

  The invention according to claim 2 of the present application is the invention according to claim 1, in which, when a small load is applied, the upper layer part not having the rib receives this, and only the upper layer part follows, When a large load is applied, the wall surface of the lattice wall of the upper layer part is tilted to the lower layer part, and the wall surface comes into contact with the rib structure of the lower layer part to receive the large load.

  The invention according to claim 3 of the present invention has a honeycomb-shaped structure which is a collection of a plurality of polygons by continuous lattice walls made of a gel-like resin, and forms a gel-like lattice body having at least an open top. The upper layer part is set to have different compressibility, bendability and buckling property between the upper layer part and the lower layer part, and the upper layer part is within the polygonal shape of the honeycomb-shaped structure constituting the gel-like lattice body. In addition, both ends of a rib made of gel resin having a plane shape lower than the height of the lattice wall from the bottom thereof are integrally formed on the inner wall of the lattice wall.

  The invention according to claim 4 of the present application is the invention according to claim 3, wherein when a small load is applied to the surface of the upper layer portion, the upper layer portion is hardly deformed and the load is applied to the lattice wall of the lower layer portion. The lower layer part is curved based on the transmitted load to disperse the load, and when a large load is applied to the upper layer surface, the upper layer part gradually maintains its form. After sinking into the lower layer portion and the upper layer portion reaching the bottom of the gel cushion, the upper layer itself collapses and the load is dispersed.

  In the gel cushion of the present invention, a gel-like lattice body having a polygonal honeycomb structure is formed by continuous lattice walls made of gel-like resin, and the compressibility, flexibility and buckling property in the vertical direction are different. With the configuration set to, the compressibility, bendability and buckling property of the upper honeycomb structure are increased, and the compressibility, bendability and buckling property of the lower honeycomb structure are set to be small so that the load on the upper layer is small. Improve the follow-up to the bed, prevent the sinking that causes the bottom to feel the bottom due to the load, improve the sleeping comfort, and lie on the bed for a long time such as a sick person or a person who needs care. Distribute the load of people who have to be able to prevent blood circulation and other disorders.

  Inside the polygonal shape of the honeycomb-shaped structure constituting the gel-like lattice body, the ribs made of gel-like resin whose plane shape is about half the height of the lattice wall from the bottom of the polygon-shaped rib are made into the inner wall of the lattice wall The gel cushion has different vertical compressibility, bendability and buckling properties, improves the followability to small loads, and prevents sinking that feels bottoming due to the load. In addition, a cushion having excellent load dispersibility can be obtained.

  The compressibility, bendability and buckling property of the gel cushion in the vertical direction are made different by integrally forming the polygonal cross-sectional size of the honeycomb structure constituting the gel-like lattice body in the vertical stacking direction. It is possible to improve the followability to a small load and prevent sinking that gives a feeling of bottoming, and to provide a cushion with excellent load dispersibility.

  A honeycomb-shaped structure having a small polygonal cross-sectional size and a honeycomb-shaped structure having a large polygonal cross-sectional size constituting a gel-like lattice body are stacked with their periphery only fixed, Since the central part of the honeycomb-shaped structure with a large square cross-sectional size is not fixed, the structure absorbs the movement other than the vertical direction such as torsion and crushing that occurs when the structure rolls over. Since the force is spread over a wide range while maintaining comfort, and the torsional movement of a polygonal honeycomb-shaped structure with a large cross-sectional size can move not only on the side of the honeycomb-shaped structure, but also over a wide range, The dispersibility of the load is further improved, and it is possible to provide a cushion that is comfortable to sleep and can prevent blood circulation disorders.

  Further, the gel cushion of the present invention is excellent in breathability, promotes absorption and divergence of sweat, and is easy to wash, so that it is possible to provide a cushion used for a bed that is easy to use.

  Furthermore, combining the upper and lower structures in reverse will increase the contact area with the skin, thus reducing the skin burden when people with sensitive skin sensations and skin damage due to edema are a concern. It becomes.

  Also, since the cross-sectional area of the honeycomb is small, the wall tilt distance due to pressing is small, so the user can reduce the sense of rolling, and the vertical and horizontal partition walls are less tilted. There is also an effect of preventing the partition wall from being deformed or loose.

Example 1
An embodiment of the present invention will be described with reference to the drawings. FIGS. 1A, 1B and 1C show Example 1 of the gel cushion of the present invention. The gel-like cushion 1 is selected from an aggregate made up of a gel-like elastomer and a gel-like viscoelastic elastomer, and is made of a gel-like resin. The gel-like cushion 1 is formed into a honeycomb-shaped structure which is an aggregate of a plurality of rectangular cross sections, with a lateral side wall 2, a longitudinal side wall 3, a transverse partition 4 and a longitudinal partition 5. The cross-sectional shape of the unit polygon of the honeycomb structure is not limited to the rectangle shown in the embodiment, but may be another polygon. A planar shape formed of a gel-like resin extending from the bottom of the polygonal cross section surrounded by the horizontal partition walls 4 and the vertical partition walls 5 of the honeycomb-shaped structure to a height lower than the height of the horizontal vertical partition walls 4 and 5 is illustrated. As shown in 1 (a) and (b), a rib 6 having a X shape or a + shape as shown in FIG. 1C is formed. Both ends of the rib 6 are integrally connected to the inner walls of the horizontal and vertical partition walls 4 and 5. The shape of the rib 6 may be any shape as long as the compressibility, bendability, and buckling property in the vertical direction of the gel cushion 1 are appropriately different. Further, the height from the bottom of the rib 6 can be lowered by increasing the thickness of the rib 6. By constructing the gel cushion 1 in this way, the compressibility, bendability and buckling of the portion where the rib 6 is not formed are the same as the compressibility, bendability and buckling of the portion where the rib 6 is formed. The upper part of the gel-like cushion 1 follows even a small load and distributes the load, and the lower part of the gel-like cushion 1 has compressibility, flexibility and buckling at the upper part. It is small compared to prevent sinking due to load.

(Example 2)
2A and 2B show Example 2 of the gel cushion of the present invention. The gel-like cushion 7 shown in the second embodiment is made of a gel-like resin selected from an aggregate composed of a gel-like elastomer and a gel-like viscoelastic elastomer. The gel cushion 7 is composed of two upper and lower portions 8 and 9. As shown in FIG. 2 (a), the upper portion 8 of the gel cushion 7 includes a lateral side wall 10, a longitudinal side wall 11, a lateral partition wall 12, and a longitudinal direction in the same manner as the gel cushion 1 of the first embodiment. The partition wall 13 is formed into a honeycomb structure that is an aggregate of a plurality of rectangular cross sections. Further, the lower portion 9 of the gel cushion 7 is formed in a honeycomb-shaped structure which is an aggregate of a plurality of rectangular sections with a lateral side wall 14, a longitudinal side wall 15, a lateral partition wall 16 and a longitudinal partition wall 17. . The difference between the upper and lower portions 8 and 9 of the gel cushion 7 is that the polygonal cross-sectional size constituting the honeycomb structure is formed such that the upper portion 8 is larger than the lower portion 9. As shown in FIG. 2 (b), the upper and lower portions 8, 9 of the gel cushion 7 are integrally formed. By forming the polygonal cross-sectional size of the honeycomb-shaped structure of the upper portion 8 of the gel-shaped cushion 7 larger than the polygonal cross-sectional size of the lower-portion 9 of the honeycomb-shaped structure, The upper part 8 of the cushion-like cushion 7 follows even a small load and distributes the load, and the lower part 9 of the gel-like cushion 7 is less compressible, flexible and buckling than the upper part. Prevent sinking due to load.

(Example 3)
3 (a) and 3 (b) show a third embodiment of the gel cushion of the present invention. The gel-like cushion 18 shown in the third embodiment is made of a gel-like resin selected from an aggregate composed of a gel-like elastomer and a gel-like viscoelastic elastomer. The gel cushion 18 is composed of two upper and lower portions 19 and 20. As shown in FIG. 3 (a), the upper portion 19 of the gel cushion 18 is an aggregate of a plurality of rectangular sections including a lateral side wall 21, a longitudinal side wall 22, a lateral partition wall 23, and a longitudinal partition wall 24. It is formed into a certain honeycomb-shaped structure. Further, the lower portion 20 of the gel cushion 18 is formed in a honeycomb-shaped structure which is an aggregate of a plurality of rectangular sections with a lateral sidewall 25, a longitudinal sidewall 26, a lateral partition 27 and a longitudinal partition 28, A sheet-like material 29 such as a non-woven fabric, cloth, tape, or paper is adhered only around the upper surface. As shown in FIG. 3B, the upper and lower portions 19 and 20 of the gel cushion 18 are formed as separate bodies, and the upper portion 19 of the gel cushion 18 is bonded only to the periphery of the upper surface of the lower portion 20. The sheet-like material 29 is sandwiched and bonded together by an adhesive or heat welding. The cross-sectional size of the polygon constituting the honeycomb-shaped structure of the upper portion 19 of the gel cushion 18 is made larger than the cross-sectional size of the polygon constituting the honeycomb-shaped structure of the lower portion 20. The compressibility, bendability and buckling property of the upper portion 19 of the gel cushion 18 are larger than the compressibility, bendability and buckling property of the lower portion 20, and the upper portion 19 is peripheral to the lower portion 20. Because of the fixed state, the twisting movement of the polygonal honeycomb-shaped structure with a large cross-sectional size can move not only on the side of the honeycomb-shaped structure but also in a wide range during movement such as turning over. Therefore, the dispersibility of the load is further improved, and the upper portion 19 of the gel cushion 18 follows even a small load, the load is dispersed, and the lower portion 20 of the gel cushion 18 is compressible. Sinking due to load is prevented because the bending property and buckling property are smaller than the upper part.

  In the present invention, a structural limitation is added to the effect that ribs having a cross-sectional shape with a height lower than that of the lattice wall are integrally formed on the inner wall. In addition, the present invention solves the problem of lack of durability such as so-called “sagging”, follows a small load applied to the cushion, and absorbs twisting (shearing force) when turning over. An object of the present invention is to provide a gel-like cushion that eliminates sinking by dispersing the load so that the user does not feel the bottom, and thus improves sleeping comfort and sitting comfort.

  For this purpose, in the present invention, in the honeycomb-shaped polygon constituting the gel-like lattice body, a planar shape having a height lower than the height of the lattice wall from the bottom thereof is a cross of a rib of X or + shape on the inside of the lattice wall. The structure is formed integrally. In other words, in the present invention, a two-stage structure is formed of a lower layer portion where X or + shaped ribs are formed and an upper layer portion where these ribs are not formed (hereinafter, such an installation method is referred to as a first installation method). Called). Thereby, the compressibility of the up-down direction of a gel-like cushion, bending property, and buckling property can be varied greatly between an upper layer part and a lower layer part.

  If a small load is applied to the gel-like cushion, it can be received by the upper layer portion having no ribs, and only the upper layer portion can follow this. On the other hand, when a large load that cannot be received only by the upper layer portion is applied, the wall surface of the lattice wall of the upper layer portion is inclined to the lower layer portion, and the wall surface comes into contact with the lower layer portion. At this time, since the large load can be received by the rib structure of the lower layer portion, it is possible to prevent a sinking that the user feels bottoming and to provide a cushion with excellent load dispersibility.

  In the present invention, the upper layer portion and the lower layer portion are clearly separated in the vertical direction. Moreover, the ribs constituting the lower layer part are formed integrally with the surrounding lattice wall and are not formed in a projecting shape, so that even if a large torsion (shearing force) is applied, the rib almost tilts. There is no.

  Further, in the present invention, the rib is limited so that the planar shape of the rib becomes x or +, and the crossing angle of the rib is approximately 90 °. That is, by limiting the crossing angle of the ribs to approximately 90 °, there is almost no tilting regardless of the direction of twisting.

  That is, according to the present invention, the compressibility, bendability and buckling property of the upper layer portion where the rib is not formed and the lower layer portion where the rib is formed can be greatly different from each other. Therefore, when a load is applied, it is possible to mainly tilt only the lattice wall constituting the upper layer portion without tilting the lower layer portion having the rib structure. In other words, the total tilt distance can be handled only by the upper layer part where the rib is not formed, and the tilt distance carried by the lower layer part can be reduced. For this reason, it is possible to greatly reduce the feeling of side swaying given to the user.

  In the gel cushion according to the present invention, the total tilt distance can be reduced. For this reason, by arranging the cushion according to the present invention on the seat surface of a wheelchair or the like, it is possible to improve the stability of the sitting position compared to a simple lattice-shaped cushion body, and it is particularly difficult to maintain the sitting position. It is also possible to provide a cushion body that reduces the tilting distance while further reducing the tilt distance for the elderly and the physically handicapped. In addition, it is possible to provide an epoch-making wheelchair that can always hold and stabilize a sitting posture of an elderly person or the like by disposing a gel cushion having the above-described configuration in a wheelchair or the like.

  The present invention can also employ a second installation method in which the apparatus is installed upside down. In this second installation method, a rib structure having a planar shape of x or + is used as the upper layer portion, and a honeycomb-like lattice wall having no rib is used as the lower layer portion. In such a case, it is possible to increase the contact area between the upper layer surface and the body surface of the user in contact with the upper layer surface, and it is possible to give a soft touch feeling to the user, and a stable and gentle skin feeling. It is also possible to continue to give a more comfortable cushion body. The deformation form of the gel cushion in such a use form is that, for example, when a small load is applied to the surface of the upper layer portion, the upper layer portion transmits the load to the lattice wall of the lower layer portion with almost no deformation. The lower layer portion is bent based on the transmitted load, thereby dispersing the load. Even when a large load is applied to the surface of the upper layer, the upper layer gradually sinks into the lower layer while maintaining its shape, and after the upper layer reaches the gel cushion bottom, the upper layer itself The load will be dispersed while crushing. In particular, when the bottom of the gel cushion is fixed with a nonwoven fabric or the like, the tilt distance of the cushion body itself is smaller than the tilt distance of the cushion body in the first installation method, and the sitting posture is more stable. It can be held.

  As described above, the gel-like cushion according to the present invention forms a spatial structure composed of roughly divided honeycomb-like lattice walls and a spatial structure surrounded by finely divided rib structures in two layers. . The tendency of tilting can be significantly different between these two layers. And in this gel-like cushion, it becomes possible to use properly the 1st installation method and the 2nd installation method by changing an upper layer part and a lower layer part.

  That is, the first installation method is desirable when a large force is applied locally such as a heel, and the second installation method is when the body and the cushion body contact over a wide range such as the back. Is desirable. In particular, the second installation method exhibits a particularly excellent effect in reducing side shaking by eliminating the bottom itself when it is necessary to take a sitting posture by lifting the backrest of the bed. Furthermore, since the second installation method can give a soft touch feeling to the user, a more comfortable use environment is provided for users who are sensitive to skin contact feeling or who are concerned about skin damage due to edema. It can also be provided.

  Also, in the first installation method and the second installation method, when the gel cushion is deformed by applying a large load to the space structure portion divided into two small parts by giving the space structure having two different shapes. Even so, the space surrounded by the walls of the honeycomb structure can be maintained at all times, so the body temperature is excellent, and it has the characteristics of easily releasing moisture such as sweat. It can be.

  The contents of 0030 are explanations for the installation method 1 in FIG. 1. Here, for 7 in FIG. 2, both 8 and 9 are combinations according to the first installation method, but both 8 and 9 are the same. A combination by the second installation method is also possible. In addition, for this combination, it is possible to configure 7 with 8 as the first installation method and 9 as the second installation method, and further, 8 as the second installation method and 9 as the first installation method. 7 can also be configured. Further, when 7 is configured as another combination, it is possible to arrange 9 in the upper part and 8 in the lower part. In this case, four combinations are possible as described above. Therefore, a total of eight combinations are possible as the combination method constituting 7. This also applies to the case of configuring 18 in FIG. These combinations are determined according to the required strength and situation of the cushioning properties, and an optimum configuration can be created.

  In addition, the present invention consisting of a two-layer structure in which the upper layer portion and the lower layer portion are clearly separated in the vertical direction can produce a large difference in deformation behavior between the upper layer portion and the lower layer portion, and thus occurs in the cushion body. The displacement force can be absorbed effectively. For this reason, it is possible to greatly reduce the decrease in blood flow in the capillaries by absorbing the shearing force generated on the body surface due to the displacement, and it is also possible to prevent the occurrence of the floor displacement itself.

  As support for this, FIG. 4 shows data obtained by measuring the body pressure dispersion of a cushion body (hereinafter referred to as a comparative example) having a spatial structure composed of a single layer of honeycomb-like lattice walls, and FIG. It is the data which measured the body pressure dispersion | distribution of the applied cushion body. Each of these data is applied to the bed so that the back-up angle is 80 °, which is the situation where the most local pressure can be generated when the cushion body to which the comparative example is applied and the cushion body to which the present invention is applied is actually used. The pressure distribution applied to each cushion body was measured with the human body sitting and placed.

  As a result, in FIG. 4, the region exceeding 40 mmHg is displayed slightly, and it is shown that a region where the pressure is locally increased occurs. This occurs because the honeycomb-like lattice wall is greatly tilted and sinks due to the load, and the load cannot be dispersed.

  On the other hand, in FIG. 5, since the area | region exceeding 40 mmHg is not displayed at all, the area | region where pressure becomes high does not generate | occur | produce, but sinking is suppressed by distributing a load. The effect is shown. In addition, the effect due to the difference in body pressure distribution during sleep becomes more prominent particularly in a state where the human body is set to a lateral posture rather than a supine posture.

  From the above-mentioned supporting results, the present invention adopting a configuration different from the comparative example is particularly suitable in the case where the user should provide more comfortable bedding and chairs with emphasis on the health of the user. The present invention has a function and effect peculiar to the present invention that does not occur in the described invention.

  In the present invention, a gel-like lattice body whose upper side is open may be formed. By opening the upper side in this way, it is possible to improve the dehumidifying property as compared with the case where the inside of the column is sealed, and it is possible to effectively absorb the shearing force (torsional force).

  Moreover, in the present invention in which the inside of the lattice body is not hermetically sealed, it does not necessarily indicate a direct type subsidence operation, but shows various bending operations according to the gravity of the object. For this reason, in the present invention, it is not possible to effectively prevent the cushion element from sinking simply by disposing the solid protrusions while paying attention only to the direct subsidence.

  Therefore, in the present invention, both ends of the ribs made of gel resin having a plane shape of x or + are integrally formed on the inner wall of the lattice wall. As a result, even if a large twist (shearing force) acts on the lattice wall, the tilt distance can be reduced by forming the inner wall and both ends of the rib integrally. In support of this, in FIG. 6, Experimental Example 1 in which the inner wall of the lattice wall and both ends of the rib are integrally formed is compared with Experimental Example 2 in which the rib both ends are not integrally formed on the inner wall of the lattice wall. It is shown that (distance AA ′) is small. For this reason, when this invention with a small tilting distance is applied as a cushion, the body can be kept stable by preventing the body from sinking.

  On the other hand, when the solid protrusions formed in the sealed lattice body are arranged as an alternative to the rib of the present invention, the solid protrusions stand vertically as shown in Experimental Example 3 of FIG. It tilts largely in the same manner as the tilting tendency of the installed vertical wall, and the tilting distance itself increases, giving the user a so-called side-shake feeling. In particular, when a twist (shearing force) is applied when turning over, this column or solid protrusion will tilt greatly, which gives great discomfort to the elderly and disabled people who use it. It will also end up.

  That is, the present invention is an optimal gel shape for contributing to the stable maintenance of the body with sufficient insight into the tilting tendency and tilting distance when a load is applied to the gel-like lattice body whose upper side is open. A new configuration for realizing tilting of the lattice is newly found, and this is set as a component of the invention.

  In such a gel cushion according to the present invention, the total tilt distance can be reduced as compared with the conventional example. For this reason, by arranging the cushion according to the present invention on the seat surface of a wheelchair or the like, it is possible to improve the stability of the sitting position compared to a simple lattice-shaped cushion body, and it is particularly difficult to maintain the sitting position. It is also possible to provide a cushion body that reduces the tilting distance while further reducing the tilt distance for the elderly and the physically handicapped. In particular, the cushion body arranged in a wheelchair etc. tends to be high in humidity because there are many cases where elderly people etc. sit continuously for a long time, but the upper part of the gel-like lattice body is opened. Then, it becomes possible to give dehumidification to a cushion body.

It is a figure which shows Example 1 of this invention. It is a figure which shows Example 2 of this invention. It is a figure which shows Example 3 of this invention. It is the figure which measured the body pressure dispersion | distribution of the cushion body which has the spatial structure which consists of 1 layer of honeycomb-like lattice walls. It is the figure which measured the body pressure dispersion | distribution of the cushion body to which this-application device is applied. It is the figure illustrated about the behavior when a big twist (shearing force) acts on a lattice wall.
