Description

air cushion

The present invention relates to an inflatable air cushion, and more particularly to an air cushion for a seat or mattress for a car or a home.

Modern people have different living habits from the past, so there are many civilized diseases that have not existed before. Among them, they have to sit for a long time due to work, injury or other reasons, resulting in poor sitting posture, long-term skin compression, poor blood circulation in the lower body, etc. Symptoms are one of the problems indirectly caused by the development of modern society.

In order to alleviate the modern people's long-term sitting on the chair, the pressure on the spine, buttocks and lower body is usually added to the seat, and the air bed is also installed on the bed at night. The structure absorbs the stress that is exerted on the body for a long time to sit down.

Referring to FIG. 5, in the prior art air cushion structure, the support sheets 91 having a plurality of rectangular sheets inside are spaced apart from each other, and the air cushion is internally partitioned into a plurality of elongated air chambers 900, and the support sheets 91 are arranged. There is at least one vent hole 92 extending therethrough to allow air between the air chambers 900 to communicate with each other. When the user inflates the air cushion, air is sufficiently transmitted through the vent holes 92 to the respective spaced air chambers 900. After the air cushion is inflated, the support piece 91 for the interval maintains the internal pressure and supports the shape of the air cushion.

However, in the prior art air cushion, in fact, the support piece 91 of the rectangular structure is pressed by a large single point force, for example, when the human body sits up from the air cushion, the single point is supported by the hand, and the support is supported. The sheet 91 cannot effectively support the entire air cushion. In other words, the structure of the single sheet makes it impossible to effectively distribute the stress evenly to the other support sheets 91 of the air cushion, so that the point is subjected to a particularly large force, and the air cushion is easy to use for a long time. Damage caused by uneven force, such as the support piece 91 somewhere is particularly weak and so on.

In addition, the vent hole 92 for opening the air on the support piece 91 is formed in the center of the support piece 91. When the support piece 91 is pressed down, the vent hole 92 also lowers the support piece 91. The force that can be withstood, so the prior art air cushion structure has its improvement.

In view of the shortcomings and deficiencies of the prior art, the present invention provides an air cushion which, by re-improving the shape of the support sheets, enables the air cushion to more effectively disperse the stress it receives and to make the structure more stable.

For the purpose of the above-mentioned creation, the technical means adopted in the present invention is an air cushion, which comprises a casing, which comprises a top plate, a bottom plate and a ring wall, and the top plate and the bottom plate are respectively connected to upper and lower sides of the ring wall. And the top plate, the bottom plate and the ring wall are overmolded with an inner space, and the housing is formed with an inflation hole formed therein, the inflation hole is communicated with the inner space of the housing; a plurality of meshes are disposed in the inner portion In the space, the grids are spaced apart from the ring wall of the casing, and each of the grids includes a plurality of side walls and a grid space, and the top ends of the side walls are fixed to the inner wall surface of the top plate. The bottom end of the side wall is fixed to the inner wall surface of the bottom plate, and the side walls surround each other to form a polygonal ring cylinder to surround the mesh space; a plurality of vent holes respectively formed through the mesh On the side walls.

Referring to FIG. 1 and FIG. 2, in the main embodiment, the number of the at least one mesh 20 is plural, and the meshes 20 and the ring walls 13 of the casing 10 are spaced apart from each other, and each of the meshes The grid 20 includes a plurality of side walls 21 and a grid space 200. The top ends of the side walls 21 are fixed to the inner wall surface of the top plate 11, and the bottom ends of the side walls 21 are fixed to the inner wall surface of the bottom plate 12, and the grids 20 are The side walls 21 surround each other to form a polygonal ring cylinder and simultaneously form the grid space 200.

The grids 20 are disposed with the side walls 21 in abutment with the adjacent grids 20, but not limited thereto, and the grids 20 may also have gaps between them, which only occupy the inner space on average. 100 can be.

The side walls 21 of the meshes 20 are formed to form a regular hexagonal column, and the mesh 20 is arranged to form a honeycomb structure with the side walls 21 and the adjacent meshes 20, but not limited thereto. The side walls 21 of the grid 20 may also be surrounded by other shapes of polygons, such as squares or triangles, and they may be arranged in other forms as well.

The adjacent two meshes 20, because some of the side walls 21 are in contact with each other, the thickness of the side wall 21 is thicker than the side wall 21 of the mesh 20 which is not adjacent to the other meshes 20, but not The adjacent two meshes 20 can also be used with the same side wall 21, so that all the sidewalls 21 have the same thickness.

Referring to FIG. 1 , FIG. 2 and FIG. 3 , in the main embodiment, the number of the at least one vent hole 30 is plural, and the vent holes 30 are respectively formed through the sidewalls 21 of the mesh 20 . More precisely, the vents 30 are located on their corresponding side walls 21 at a position adjacent to the inner wall surface of the top plate 11 or the inner wall surface of the bottom plate 12, and in two adjacent nets. The vents 30 communicate with the two grid spaces 200 of the two adjacent grids 20 on the side walls 21 between the grids 20, and on the side walls 21 of the grids 20 that are not adjacent to the other grids 20, The vent hole 30 communicates with the internal space 100 of the housing 10.

Referring to FIG. 4, another embodiment of the present invention is substantially the same as the main embodiment. However, in another embodiment, the number of the at least one mesh 20A is one, and the mesh 20A also includes a plurality of The sidewall 21A is surrounded by a grid space 200A, and the sidewall 21A of the grid 20A further has at least one vent hole 30A. In another embodiment, the number of the at least one vent hole 30A is one, and the vent hole is 30A is disposed on the side wall 21A adjacent to the inner wall surface of the top plate, but not limited thereto, the vent hole 30A may also be plural, and the vent hole 30A may be disposed at a position close to the inner wall surface of the top plate or the inner wall surface of the bottom plate. It can be adjusted according to the needs of users.

The following is a brief description of the state of use of this creation and its advantages.

Referring to FIG. 1 , in the present application, the air is introduced into the inner space 100 of the casing 10 through the inflatable hole 15 through the inflatable member 15 , and further penetrates the vent holes 30 to gradually diffuse the air. In the grid space 200 spaced apart from each other, when the interior space 100 of the creation is filled with air, the inflation can be stopped for the user to use.

An advantage of the present invention is that since the side walls 21 of the mesh 20 are circumferentially shaped into a polygonal shape, when the surface of the casing 10 is subjected to a force, the force is transmitted to the side walls 21 of the annular structures, the annular The polygonal structure can support the shape of the creation more stably, and at the same time effectively spread the pressure in other directions, avoiding the pressure from being concentrated at the point of the force application. This feature allows the user to sit on the creation when The pressure is released evenly and feels comfortable, and on the other hand, because of the relatively even sharing of pressure, the durability of the mesh 20 is also high.

In addition, since the vent holes 30 are opened at the top end or the bottom end of the corresponding side wall 21, when the force is pressed down, the stress can be prevented from being excessively concentrated on the periphery of the vent hole 30, thereby avoiding the high wear rate at the place. It is easier to damage.

In summary, the air cushion of this creation has a good performance regardless of durability or comfort in use.
