Description

Bedding cushion including air cell {PRODUCT FOR CUSHION}

The present invention relates to a cushion for bedding including an air cell, and more particularly, to a cushion for a bedding cushion including an air cell, and more particularly to a cushion for a bedding cushion including an air cell, The vertical load caused by the body weight of the body is effectively dispersed not only by the elasticity of the second bearing portion but also by the horizontal load by the principle of Pascal in the first bearing portion, and the size of the airgel is ergonomically The present invention relates to a cushion for bedding including an air cell which is formed to be applied differently so as to provide comfortable comfort to the user, and a method of manufacturing the cushion for the bedding.

Generally, a cushion for a bedding cushion having a cushioning force and an elastic restoring force is made of a latex having a cushioning and stretching restoring force, a spring having an elastic supporting force, and the like.

The cushioning material for a bedding material using the latex or a spring has a problem of deterioration of the elastic supporting force due to deterioration of the spring due to aging of the spring and a problem of lowering elasticity and restoring force of the latex depending on the load continuously applied to the latex material.

As a conventional technique for solving such a problem, there has been disclosed a cushioning material composed of a plurality of blower-molded plastic buckets having self-elasticity such that air is sucked or discharged while being deformed or restored according to an external force, and an inner cushion disposed between the plastic buckets And each of the plastic buckets is in a state of being bound together by means of wires or the like with the inner cushion interposed therebetween.

Accordingly, it is possible to control the elasticity of the cushioning material by controlling the amount of air of the plastic bottle so as to adjust the cushioning material to have an optimal cushioning degree.

However, there is a problem that the plastic bucket and the inner cushion are not integrated and the respective parts of the body can not be supported with appropriate pressure.

That is, when a load acts on any one of the plastic buckets, the plastic bucket is pushed and the side portions thereof are pushed toward the inner cushion. Since the boundary portion between the inner cushion and the plastic bucket is in contact with each other, There is a problem that the load distribution function of the plastic bucket and the inner cushion is remarkably deteriorated.

As a solution to this problem, Patent No. 1032462 (Apr. 25, 2011) is a plastic bottle for air mattress that minimizes the total volume by compressing the inner space of the plastic bottle when storing or transporting. 1032460 (Apr. 25, 2011) is an air bed which uses a plastic bottle to adjust the elasticity of the air mattress and to distribute the load to the entire bed even when the load is concentrated on only a part of the mattress, and is disclosed in Patent No. 956662 .29.) Is a bed for patients using plastic buckets that allow the mattress of the bed to be folded smoothly along the unit frames.

However, since the prior art plastic bottle-shaped chambers or cushions are artificially inflated by air supply, and the operation of sucking in air itself is impossible, so that in order to inject air into the chamber or cushion in the form of a plurality of plastic buckets, Therefore, there is a problem in that the size and capacity of the pump are increased, the useless use is caused by driving the pump, and the production cost is increased.

In addition, when the plastic beater-shaped chambers or cushions are made of a cushion body for a bed or other purposes, since the cushion body is compressed and the volume thereof is reduced, transportation and delivery are impossible. There is a problem.

Further, the plastic bottle has a problem in that the foam (spacer) is detachable and the air in the plastic bottle is faded, so that the compression and restoration force is lost and the volume of the plastic bottle can not be reduced.

The mattress using the latex and air tube of Patent No. 510004 is a product in which the outer material of the mattress is made of latex and the inner material is made into an air tube.

The mattress is prepared by injecting air into the air tube and preparing a liquid latex inside the mold in a state where the air tube into which the air is injected is positioned at the center of the inside of the mold so that the latex is molded around the air tube, It is manufactured by curing an external material.

However, in the mattress described above, since each cell is separately and independently positioned from each other, the pressure rise of the air tube limits the cushioning role by only stiffening the tube. Such an increase in the rigidity of the tube has a drawback in that it only creates a pressure point, thereby increasing the inconvenience.

In addition, the conventional mattress is formed in the shape of a straight tube so that the mattress can not act selectively on the load acting on each part of the body, and the comfort is lowered.

Further, conventional mattresses have a problem in that they are not bonded to each other due to the characteristics of the latex material and the tubes of the synthetic resin.

The first receiving part 10 includes a first film 12 and a second film 14 which is integrally formed with the first film 12 by thermally fusing.

The first and second films (12) and (14) are preferably formed of TPU. Of course, the present invention is not limited thereto, and any synthetic resin having flexibility, durability, and ease of manufacture can be used.

The first film 12 is formed in a plate shape. Which functions to close the lower end of the second film 14. [

The first film 12 includes an air inlet 122 through which air is injected into the second film 14. The air inlet 122 functions to inject air into the second film 14. The air inlet 122 has a general structure such as a well known air inlet formed in tubes used by filling air therein . The air inlet 122 may be formed at one side of the second film 14 and air may be injected between the first and second films 12 and 14 It can be formed anywhere that the air cell can be easily formed.

The air inlet 122 may be exposed to one side of the second receiving unit 20 so that the amount of air injected into the first receiving unit 10 is adjusted according to the user's selection, It should be comfortable to use depending on the condition or the user's choice.

The second film (14) is thermally welded to the rim of the first film (12) to have a certain width.

The second film 14 has a frame 142 having a predetermined width and integrated with the rim of the first film 12 and air pockets filled with air at the inside of the rim 142 to form air pockets having a predetermined height And a communication hole 146 for allowing air communication between a plurality of air cells 144 and neighboring air cells 144.

The communication hole 146 is composed of first and second holes 1462 and 1464.

The first hole 1462 is formed to have a constant height at the bottom, and the second hole 1464 is formed to have a constant height at the first hole 1462. That is, the first and second holes 1462 and 1464 are formed in a stepped shape. In this case, the first hole 1462 is formed in a rectangular shape of a rectangular shape, and the second hole 1464 is formed in a semicircular shape.

This controls the amount of air flowing through the communication hole 146 according to the magnitude of the load applied to the air cell 144, thereby providing a comfortable comfort to the user. That is, when the load acting on the air cell 144 is small, the first air hole 1462 is formed in a wide range of a rectangular shape, and the second air hole 1464 is formed in a semicircular shape, 144) is large, a large amount of air flows.

The communication hole 146 is formed in a stepped manner by the first and second holes 1462 and 1464 so that when the communication hole 146 is pressed by the user, So that the air flow between neighboring air cells 144 can be smoothly performed.

The second bearing portion 20 is configured so that the entire first bearing portion 10 is included inside, thereby providing a comfortable feeling to the user in accordance with the intended use. In this case, the air cell 144 of the first receiving unit 10 is also bent in such a manner that the curved portion of the second receiving unit 20 is curved. In other words, when the receiving unit 20 is a pillow, So that the height is different. In addition, when the receiving portion 20 is a mattress, a curvature is formed so as to be comfortably supported by the base in accordance with the body conditions such as neck, waist, and legs. Of course, the present invention is not limited to this, but it is preferable that the receiving portion 20 is maintained in an ergonomically bent state in accordance with the purpose of use and body conditions. However, it may be formed flat in some cases, (10).

In addition, it is preferable that the second receiving portion 20 includes the entire first receiving portion 10 therein. Of course, the present invention is not limited to this, and may be configured such that the first receiving portion 10 is positioned at one end and the second receiving portion 20 is formed at an upper portion thereof.

In addition, it is preferable that the second bearing portion 20 is formed of any one of latex, memory foam, and foamed urethane. Of course, the present invention is not limited thereto, and any material and ergonomic shape used in the market can be used according to the intended use.

The first supporting part 10 is a TPU and the second supporting part 20 is a urethane type such as a memory foam so that the bonding force between the first and second supporting parts 10, So that it is possible to maintain a firm bonding force without forming a separate means for increasing the strength of the screw.

A method of manufacturing a bedding cushion constructed as described above will be described with reference to FIG.

In the air cell forming step S1, a plurality of air cells 144 are formed on the second film 14 on the plate by pressing the second film 14 through a pressing means such as a press. Of course, a communication hole 146 through which air is communicated is formed in a space between neighboring air cells 144. In this case, it is preferable that the second film 14 is formed by a vacuum molding method as a method of forming an air cell.

The first film lining step S2 is performed by positioning the first film 12 at the lower end of the second film 14 formed with the air cell 144 through the air cell forming step S1, The first and second films 12 and 14 are thermally pressed so that the rims of the first and second films 12 and 14 are integrated by thermal fusion. Accordingly, by opening the lower part of the air cell 144 and the communication hole 146 formed in the second film 14 by the first film 12, air can be injected into the air cell 144 do.

In this case, the air inlet 122 is fixed to one side of the first film 12. At this time, the air inlet 122 is formed to have a predetermined length so as to be exposed to the outside of the second support portion 20. [

In addition, the first and second films 12 and 14 may be fusion-bonded to each other by a high-frequency welding method.

The second supporting member foaming step S3 is a step in which the first supporting part 10 in which the first and second films 12 and 14 are integrated through the first film laminating step S2 is provided with the second supporting part 20 Is foamed to complete a cushion for bedding in which the first and second receiving portions 10 and 20 are integrated.

In this case, air is injected into the first bearing unit 10 so that the air pocket has a natural shape. In this case, the amount of air injected is 50 to 80% It is preferable that the second support portion 20 is foam-molded. If the amount of air injected is less than 50%, the amount of foaming of the second support part 20 is increased by the amount of foaming of the second support part 20 when the first support part 10 is fanned in a small state, If the amount of air introduced into the second support part 20 is less than that of the second support part 20, the cushion specific to the second support part is lost, There is a problem to lose.

The cushion for bedding formed through the above-described manufacturing method is characterized in that when the air is injected through the air inlet 122 formed at one side of the first or second film 12 or 14 of the first supporting part 10, Air flows through the communication holes 146 formed between the plurality of air cells 144 formed on the second film 14 and the neighboring air cells 144 so that the air cells 144 rise due to the amount of the injected air And functions as an air pocket.

For example, the pillow 1 composed of the first and second support portions 10 and 20 is supported by the user's neck primarily through the second support portion 20. [ At this time, the pressing force acting on the second receiving portion 20 is primarily received by the elastic force of the second receiving portion 20, and the pressing force acting on the second receiving portion 20 is greater than the pressing force acting on the plurality of air cells 144 ).

In this case, since the air injected into the air cell 144 flows through the communication hole 146 of the plurality of air cells 144, the load acting on the air cell 144 is uniformly distributed to provide a comfortable feeling of comfort do.

This is because the second support part 20 absorbs a load of a certain part by the load of the neck and is transmitted to the first support part 10, and the remaining load thus applied acts on the plurality of air cells 144.

At this time, air is dispersed into the neighboring air cells 144 through the communication holes 146 formed in the four sides of the air cells 144 injected with the air by the load acting on the air cells 144. In this case, The air of the air cell 144 that receives the load is transmitted to the air cells 144 of the other air cell 144 to provide comfort to the users by the supporting force and the dispersing force. will be.

In addition, the air cell 144 provides a comfortable feeling of comfort by not only a vertical load but also an easy dispersing action of the load due to elasticity even when a load acts on the side.

Also, even if the communication hole 146 of the first receiving portion 10 is pressed by the acting load, the communication hole 146 is formed to be stepped into the first and second holes 1462 and 1464, A part of the air cell 146 is maintained in an opened state, and the distribution of the load through the plurality of air cells 144 is performed, so that a comfortable feeling of comfort can be maintained.

The amount of air injected into the first pedestal 10 through the air inlet 122 exposed on one side of the outer periphery of the second pedestal 20 may be adjusted to adjust the height of the first pedestal 10, The cushion condition can be adjusted to provide ease of use.

The second bearing portion 20 maintains its own hardness such that it can maintain its overall shape while retaining its own elasticity such as latex or memory foam, Shock absorbing performance and load-dispersing performance due to elasticity and air flow in accordance with the physical condition of the second bearing part 20 or the demand of the user, so that the shape of the cushion itself is maintained due to the softness and hardness of the second bearing part 20 While providing a comfortable feeling of comfort due to the shock absorption and load distribution performance of the first support portion 10.

The second support part 20 penetrates into a space between a plurality of air cells formed in the first support part 10 by a hardness maintaining the shape of the second support part 20, Thereby supporting the load distribution force acting on the cushion smoothly, thereby maintaining a sense of stability.

The first pedestal 10 can regulate the air injection amount of the air cells formed in the first pedestal 10 through the air inlet 122 exposed outside the second pedestal 20, It can be used as a body type customized to improve comfortable comfort by adjusting the shape or comfort of the cushion according to the user's body condition, that is, the body shape.

That is, the conventional bedding cushions are formed in a regular shape or shape and are not adapted to the physical condition of the user, so that the user can manually adjust the cushion to be provided with at least one cushion according to the conventional bedding cushion, The cushion for bedding according to the present invention is an active type body-customizing cushion which can be adjusted so as to be adapted to the body shape of the user, thereby providing ease of use and comfort.

As shown in FIG. 5, the mattress using the cushion for bedding according to the present invention is composed of a second bearing portion having a first bearing portion on its inner side, and the first bearing portion is configured to be ergonomically different in height The amount of air injected into the first pedestal portion is adjusted according to the body condition and the user's selection, thereby providing a comfortable feeling of comfort.
