Definitions
- the present invention relates to a cushion in which fluid is accommodated in a movable state inside the cushion body.
- a cushion filled with a fluid is sometimes used in order to obtain a comfortable cushioning property (see, for example, Patent Document 1).
- This cushion has a shoulder pad and a waist pad, and is a water cushion for backrest that is configured to fit the shoulder and the waist. It is divided into rooms.
- An elastic cushion covering the shoulder pad and the waist pad is disposed on the front surface of the substrate on which the shoulder pad and the waist pad are disposed, and the surface thereof is covered with a skin material. Since it comprised in this way, in this cushion, the movement of the water inside a shoulder pad and a waist pad is controlled, and the cushioning property suitable for a backrest is obtained.
- this cushion a plurality of chambers and weir bodies are formed irregularly, and the weir bodies are scattered inside the chamber, so that a user can ride on the cushion or a user on the cushion. It is difficult for water to move in an arbitrary flow path when the posture is changed.
- the present invention has been made to address the above-described problems, and its purpose is to make the movement of the fluid when the body weight is loaded follow an arbitrary flow path, thereby making the hardness felt by the user. It is to provide a cushion that can have different (softness) depending on each part of the body.
- the reference numerals of corresponding portions of the embodiment are shown in parentheses in order to facilitate understanding of the present invention.
- the present invention should not be construed as being limited to the configurations of the corresponding portions indicated by the reference numerals of the forms.
- the structural feature of the cushion according to the present invention is that the plurality of storage portions (11a, 21a) arranged in the front, rear, left, and right and the storage portions adjacent to each other of the plurality of storage portions communicate with each other.
- a cushion main body (11, 21) made of a flexible flat bag-like film formed with a plurality of communication paths (11b, 11c, 21b, 21c), and enclosed in the cushion main body,
- W weight
- the cushion when a load is applied to a predetermined portion, the pressure in the cushion body becomes non-uniform, so that the fluid in the cushion body moves so that the pressure in the cushion body becomes uniform. For this reason, when a load is applied to the cushion, a fluid flow path is generated in the cushion body.
- the cross-sectional areas when the fluid passes through the plurality of communication passages are different from each other, and the amounts of fluid passing through the plurality of communication passages are different from each other. According to this, when a person's weight is applied to the cushion, each part deforms quickly because the flow resistance is small and the fluid moves fast, and deforms slowly because the flow resistance is large and the fluid moves slowly.
- the part is divided into a part in which the fluid resistance is in the middle and the fluid moving speed and the deformation speed are in the middle.
- the cushion user feels that the hardness of each part is different, such that the part where the fluid moves fast feels soft, and the part where the fluid moves slowly feels hard, along the fluid flow path. Gradually, changes in hardness can be felt from soft parts to hard parts.
- a cushion having each part having an appropriate hardness according to the body part is obtained. be able to. That is, by promoting or suppressing the movement of the fluid in a specific direction, it is possible to give anisotropy to the movement of the fluid, thereby controlling the flow direction and order of the fluid. Also, when the body moves on the cushion, the fluid moves following the movement of the body, and when the body is separated from the cushion, the cushion is restored to the original state.
- the flow path extending linearly may be formed by making the cross-sectional area of the communication path located around the assumed flow path smaller than the cross-sectional area of the other communication path, A plurality of regions may be set, and the cross-sectional area of the communication path may be changed for each region.
- the cross-sectional area becomes “0” when the communication path is closed, but when the fluid passes, the communication path widens to have a predetermined cross-sectional area, and the cross-sectional area is reduced.
- the cross-sectional area when the fluid in the communication passage passes assumes that the cross-sectional area is maximum.
- the amount of fluid passage may be different by changing the width of each communication passage so that the cross-sectional area of the flow path through which the fluid passes is different. The amount of fluid passing may be changed by providing an object, a weir, or the like through which the fluid can pass inside.
- all the adjacent accommodating portions may be communicated with each other through the communication path, or only a part of the adjacent accommodating portions may be communicated with each other through the communication path.
- air or water is preferably used as the fluid.
- a plurality of housing portions are communicated with a large passage region including a housing portion communicated with a communication passage having a large cross-sectional area, and a communication passage having a small cross-sectional area.
- the main flow path of the fluid when the user's weight is applied to the central portion of the cushion is the flow path from the large path area to the small path area when the weight of the user is applied to the central portion of the cushion. It is in that.
- the region is a large continuous passage region and a small continuous passage region, but an intermediate region may be provided.
- the fluid flow path is a flow path that advances from the Dalian passage area to the small passage area via the intermediate area.
- the central portion of the cushion is a portion to which the largest load is applied when the user uses the cushion, and may be displaced from the center in terms of position.
- Still another structural feature of the cushion according to the present invention is that it is used for sitting, and when the weight of the user is applied to the central portion, the main flow path of the fluid starts from the central portion (A) of the cushion body.
- the flow path is directed from the both side parts (C1, C2) to the front part (D) after going to the rear part (B).
- the cushion is used for sitting, that is, installed on a seat such as a chair or a sofa.
- a seat such as a chair or a sofa.
- the heel portion is positioned at the central portion of the cushion and the thigh portion is positioned at the front central portion.
- the fluid in the cushion flows from the part corresponding to the collar part to the rear of the collar part, and moves from both sides of the collar part to the front part along the outside of the thigh part. According to this, since the fluid slowly moves in the flow path described above, the thigh portion is not compressed immediately after sitting, and a comfortable seating becomes possible.
- Still another structural feature of the cushion according to the present invention is that a porous elastic member (14, 24) is installed inside the cushion body.
- the cushioning property of each housing part can be further enhanced, and the deformation of each housing part becomes gradual, and the sitting comfort suitable for the cushion is achieved. Occurs. That is, when the housing portion is recessed due to the weight load on the cushion, moderate elasticity can be given, and when the housing portion is restored to its original shape, it is reliably restored by the elasticity of the elastic member. It becomes like this.
- Still another structural feature of the cushion according to the present invention is that the fluid injection pump (31) and the fluid discharge valve (33) are connected to the cushion body so that the pressure of the fluid in the cushion body can be adjusted. There is.
- the pressure of the fluid in the cushion body can be set to an arbitrary value so as to have an arbitrary hardness. it can.
- the tension of the cushion body varies depending on the temperature and atmospheric pressure, but the cushion according to the present invention can adjust the pressure of the fluid in the cushion body, so that it can be used in an optimum state regardless of the place and the season. .
