Description

Gel-shaped cushion {GEL-TYPE CUSHION}

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

A cushion used for a bed or the like requires not only a function of supporting and maintaining a human body weight but also a comfortable bed. In order for a dragonfly to be a comfortable cushion, it needs to meet the requirements of moderate softness, compressibility, vibration absorption, dehumidification, deformation following or not to settle down. Background Art Conventionally, webs of cotton or synthetic fibers, synthetic resin foams such as polyurethane foams, coil springs, and the like have been used alone or in combination.

In addition, some cushion rubbers used in a bed or the like are made of sponge rubber, a semi-hard material or a gel material, or arranged in a columnar shape, and a partition wall formed of these materials has been developed side by side in a lattice shape. .

However, in the case of the lattice-shaped cushion composed of columnar and partition walls made of sponge rubber, the cushioning is made possible by the compressibility of the sponge rubber of the partition walls. In the case of the lattice-shaped cushion having the partition wall made of a semi-rigid material, since the cushion property is imparted by the inclined movement of the semi-barrier material forming the partition wall, there is a problem that the softness is less and the buffering property corresponding to the small load is inferior. . In addition, since both become difficult to absorb the torsion (shear force) generated when lying down, requiring large muscle movements when lying down, it is easy to prevent sleep. In the case of a lattice-shaped cushion having a partition material made of a gel material, the cushion property is good because the cushion property is imparted by the flexibility and the buckling property of the gel material that constitutes the partition wall, but the cushion material has good cushioning properties, so it falls down early because it is a gel material. It had a problem of durability.

In view of the above problems, the present invention is durable and follows a small load, absorbs the torsion (shearing force) at the time of lying down, and uses it for a bed with a comfortable bed without falling down to the extent that it touches the floor. It is an object to provide a gel cushion.

In order to solve the said subject, the 1st invention of this application forms the gel lattice body of the honeycomb structure which is an aggregate of a plurality of polygons by the continuous lattice wall made of gel-like resin in a gel-like cushion, It is characterized by setting different compressibility, flexibility and buckling of the up and down direction.

According to a second aspect of the present invention, in the gel cushion of the first aspect of the invention, in the polygon of the honeycomb structured body 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 x or + in shape. A resin rib is formed integrally with the inner wall of the lattice wall.

The third invention of the present application is characterized in that the gel cushion of the first invention is integrally molded by varying the cross-sectional size of the polygons of the honeycomb structured body constituting the gel-like lattice body in the vertical direction.

According to a fourth aspect of the present invention, in the gel cushion of the first aspect of the present invention, the honeycomb structure having a large cross-sectional size of the polygon and the honeycomb structure having a small cross-sectional size of the polygon in the honeycomb structure that constitute the gel-like lattice body are only surrounded therein. It is fixed and laminated.

The honeycomb structured body is formed of a gel-like resin extending from the bottom of the polygonal cross section surrounded by the transverse bulkhead 4 and the longitudinal bulkhead 5 to a height lower than the height of the transverse bulkheads 4 and 5, Ribs 6 are formed in which the planar shape is a X shape as shown in Figs. 1A and 1B or a + shape as shown in Fig. 1C. Both ends of the rib 6 are integrally connected to the inner walls of the partition walls 4 and 5 in the horizontal and vertical directions. The shape of the rib 6 may be any shape as long as the compressibility, flexibility, and buckling property of the gel cushion 1 in the vertical direction are appropriately different. In addition, the height from the bottom of the rib 6 can be lowered by making the thickness of the rib 6 thick. By configuring the gel cushion 1 in this manner, the compressibility, flexibility and buckling of the portion where the ribs 6 are not formed are larger than the compressibility, flexibility and buckling of the portion where the ribs 6 are formed. The upper part of the gel-like cushion 1 tracks even a small load and distributes the load, and the lower part of the gel-like cushion 1 prevents falling due to the load because the compressibility, flexibility and buckling are smaller than the upper part. .

As shown in FIG. 2B, the lower portion 9 of the gel-like cushion 7 includes a horizontal side wall 14, a vertical side wall 15, a horizontal partition wall 16, and a vertical partition wall ( 17) to form a honeycomb structured body which is an aggregate of a plurality of rectangular cross sections. The difference between the upper and lower portions 8 and 9 of the gel cushion 7 is that the upper portion 8 is formed larger than the lower portion 9 in the cross-sectional size of the polygons constituting the honeycomb structured body. As shown in Fig. 2C, the upper and lower portions 8 and 9 of the gel cushion 7 are integrally formed. By forming the cross-sectional size of the polygons constituting the honeycomb structure of the upper portion 8 of the gel-shaped cushion 7 larger than the cross-sectional size of the polygons constituting the honeycomb structure of the lower portion 9, the gel-shaped cushion ( The upper portion 8 of 7) tracks even a small load, and distributes the load, and the lower portion 9 of the gel cushion 7 is less compressive, flexible and buckled than the upper portion due to the load. This will prevent you from falling down.

As shown in FIG. 3C, the upper and lower portions 19 and 20 of the gel cushion 18 are formed separately, and the upper portion 19 of the gel cushion 18 is the lower portion 20. The sheet-like article 29 adhered only to the periphery of the upper surface is sandwiched by an adhesive or thermal welding to be integrated. The cross-sectional size of the polygons constituting the honeycomb structure of the upper portion 19 of the gel cushion 18 is larger than the cross-sectional size of the polygons constituting the honeycomb structure of the lower portion 20. The compressibility, bendability and buckling of the upper portion 19 of the gel cushion 18 is greater than the compressibility, bendability and buckling of the lower portion 20, and the upper portion 19 is fixed around the lower portion 20 only. Since it is in the state, when twisting or moving, the torsion and distortion of the polygonal honeycomb structure having a large cross-sectional size can act not only on the side of the honeycomb structure but also on a wide range. The upper portion 19 of 18) tracks even a small load and distributes the load, and the lower portion 20 of the gel cushion 18 has a lower compressibility, flexibility, and buckling than the upper portion. This will prevent you from falling down.

In the gel cushion of the present invention, a gel lattice of a polygonal honeycomb structure is formed by a continuous lattice wall made of gel resin, and the upper layer is formed by differently setting the compressibility, the flexibility and the buckling property in the vertical direction. By increasing the compressibility, flexibility and buckling of the honeycomb structure of the lower layer, the compressibility, bendability and buckling of the honeycomb structure of the lower layer are set to be small, improving the followability to small loads in the upper layer, and It has a function to prevent it from falling down so that it feels like being touched, and it makes the bed comfortable. Also, when it is necessary to lie in bed for a long time such as a sick person or a person who needs nursing care, the weight of a person is dispersed to prevent blood circulation disorder. can do.

In the polygonal structure of the honeycomb structural body constituting the gel lattice structure, a gel resin rib having a planar shape of about half the height of the lattice wall height x or + from the bottom thereof is integrally formed on the inner wall of the lattice wall. By varying the compressibility, flexibility, and buckling of the gel cushion in the vertical direction, it improves the followability to small loads and prevents it from falling to the floor due to the load, thereby providing a cushion having excellent load dispersibility. can do.

According to the configuration in which the cross-sectional size of the polygons of the honeycomb structured body constituting the gel-like lattice body is integrally formed in the vertical stacking direction, the compressibility, flexibility, and buckling property of the gel-shaped cushion are changed in different directions, and the following characteristics can be followed. It is possible to improve and prevent it from falling down to a feeling of touching the floor, thereby providing a cushion having excellent load dispersibility.

A honeycomb structure having a large polygon cross-sectional size by a structure in which a honeycomb structure having a small polygon cross-sectional size and a honeycomb structure having a large polygon cross-sectional size are fixed and stacked only around the honeycomb structure that constitutes a gel lattice structure. Since the center of the body is not fixed, the force is broadly expanded while absorbing movements other than the vertical direction such as torsion or distortion generated during the movement of the structure, such as turning over and maintaining the comfort of the skin surface. As the torsion or distortion of the polygonal honeycomb structure of large cross-sectional size can act not only on the side of the honeycomb structure but also on a wide range, the load distribution is further improved, which makes the bed comfortable and prevents blood circulation disorder. Can be provided.

In addition, the gel cushion of the present invention can provide a cushion for use in a bed or the like which is excellent in breathability, promotes absorption / dissipation of sweat, is easy to wash, and is easy to use.

In addition, by inverting the upper and lower structures, the contact area to the skin is increased, thereby reducing the burden on the skin when there is a risk of skin damage due to a person with sensitive skin sensation or edema.

In addition, since the cross-sectional area of the honeycomb structure is small, the inclined movement distance of the wall due to the pressurization is reduced, which can reduce the sense of horizontal fluctuation felt by the user, and also because the inclined movement of the horizontal and horizontal bulkheads is small, due to long-term use There is also an effect of preventing the deformation and fall of the partition wall generated in the vertical and horizontal.
