Description

  The present invention relates to an air-injection pillow that can be adjusted in height for each place by injecting air.

  If you do not use pillows that are appropriate for the person who uses them, your physical condition and health may be harmed. For example, a pillow that is too low tends to cause stress on the sympathetic nerves around the neck and cervical vertebrae, causing insomnia, nausea, dizziness, and headaches. On the other hand, too high a pillow tends to cause tension on the back muscles of the neck, causing neck pain and stiff shoulders. For this reason, some people make custom pillows that suit them. However, custom-made pillows are considerably more expensive than general-purpose pillows. Even if you pay a lot of money to make a pillow order, the pillow may not fit within a month. The human body changes day by day, such as the condition of the cervical spine and muscle tension. For this reason, in order to maintain physical condition and health, it is necessary to periodically adjust the height of the pillow. However, conventional pillows have a structure that accommodates granular materials such as beads, pipe chips, buckwheat husks, fibrous materials such as cotton and feathers, and lump materials such as low-resilience polyurethane foam mats as cushion materials. Therefore, it was difficult to adjust the height periodically.

  In view of such a situation, an air-injection pillow having a cushion bag in which an internal space is partitioned into a plurality of air chambers has been proposed (for example, Patent Documents 1 to 3). This air-injection pillow can inject air into each air chamber independently. By adjusting the amount of air injected into each air chamber, its height can be adjusted to the location (air chamber). ) Can be adjusted for each. However, when injecting air into each air chamber, the conventional air-injected pillow attaches a mouth to the air inlet provided independently in each air chamber and blows air (breath), It was necessary to connect a manual pump or the like to the air injection port to inject air, and the amount of air injected into the air chamber could not be easily adjusted. In particular, when a large number of air chambers are provided, a troublesome air injection operation has to be performed many times, which is very troublesome.

  The present invention has been made to solve the above-described problems, and can easily perform air injection work into each air chamber, and adjust the height for each place according to the state of the body of the pillow user. It is an object of the present invention to provide an inflatable pillow that can be easily performed.

The above issues
The interior space is partitioned into a plurality of air chambers and includes a cushion bag in which an air inlet for injecting air into the plurality of air chambers is provided for each air chamber,
By independently adjusting the amount of air injected into the plurality of air chambers for each air chamber, an air-injected pillow having a structure in which the height can be adjusted for each location,
Each of the air chambers in the cushion bag is filled with an air chamber inflating material made of a porous elastic material having communicating bubbles,
With one air inlet open, pressure is applied to the part of the cushion bag forming the one air chamber connected to the one air inlet on the outer surface of the cushion bag to fill the inside of the one air chamber When squeezed together with the one air chamber inflating material, the air present in the one air chamber is discharged from the one air inlet,
When the pressure is removed from the state in which the one air chamber is crushed, the one air chamber inflating material expands to expand the one air chamber, and the one air inlet opens the one air chamber. This is solved by providing an inflatable pillow characterized by allowing air to naturally flow into the air chamber.

  Thus, the simple operation of opening the one air inlet, allowing the air to naturally flow into the one air chamber, and closing the one air inlet when the one air chamber reaches a desired height. It becomes possible to adjust the height of the one air chamber only. At this time, it is not necessary to inject air (breath) into the one air inlet and use a tool such as a manual pump. Even when the cushion bag is provided with a large number of air chambers, it is only necessary to repeat the simple air injection operation. Also, when all air chambers are crushed, all air inlets are opened to allow air to naturally flow into each air chamber, and when no more air enters all air chambers, all air injection is performed. If the entrance is closed, the height of each part of the pillow can be easily adjusted to a height corresponding to the condition of the pillow user's body.

  However, a usage mode in which air is blown by attaching a mouth to the air inlet or the height of each air chamber is adjusted using a tool such as a manual pump is not excluded from the technical scope of the present invention. “When the pressure is removed from the state in which the one air chamber is crushed, the one air chamber inflating material expands to expand the one air chamber, and from the one air inlet, The description that “the air naturally flows into one air chamber” means that “when the pressure is removed from the state where the one air chamber is crushed, the one air inlet is connected to the one air chamber. It simply means that air naturally flows into the air chamber (can naturally flow in). That is, the method of adjusting the height of the actual air chamber in the air-injection pillow is not limited. First, it is possible to roughly adjust the height of each air chamber by letting air naturally flow into each air chamber, and then finely adjust the height of each air chamber using a tool such as a manual pump. . Even in this case, the labor required for adjusting the height of each part of the pillow can be reduced.

  In the air injecting pillow according to the present invention, the air chamber inflating material to be filled in each air chamber is not particularly limited as long as it is a porous elastic material having communicating bubbles. The reason why the air chamber inflating material is required to be porous having open air bubbles is to allow air to spread throughout the air chamber filled with the air chamber inflating material. Further, the reason why the elasticity of the air chamber inflating material is required is that the cushion bag of the portion in which the air chamber inflating material is accommodated by the elasticity of the air chamber inflating material when the pressure for crushing the air chamber is lost. This is so that it can be spread from the inside. There are various types of such materials. For example, a sponge is suitable. As the sponge, those made by foaming a synthetic resin such as polyurethane can be suitably employed, but natural sponges can also be employed.

  In the air injecting pillow according to the present invention, the shape and arrangement of the plurality of air chambers in the cushion bag are not particularly limited, but it is preferable to partition into five air chambers as follows. That is, the interior space of the cushion bag includes a first air chamber for supporting the center of the back of the head of the pillow user, a second air chamber for supporting the upper right of the back of the pillow user, and the pillow user. A third air chamber for supporting the upper left back part of the back of the head, a fourth air chamber for supporting the lower right part of the back of the head of the pillow user, and a fifth air chamber for supporting the lower left part of the back of the head of the pillow user. The structure is divided into air chambers. Thereby, it becomes possible to adjust the height of the pillow finely and easily according to the condition of the body of the pillow user.

  As described above, according to the present invention, air can be easily injected into each air chamber, and the height can be easily adjusted for each place according to the state of the body of the pillow user. It becomes possible to provide an infusion pillow.

A cushion bag in pillow inflatable shown in FIG. 1 is a sectional view showing a state taken along a Y ₁ -Y ₁ side in FIG. 2. It is the top view which showed the cover in the air injection type pillow shown in FIG. With the air inlet open, pressure is applied to the cushion bag to crush the air chamber together with the air chamber inflating material filled in the air bag, thereby discharging the air present in the air chamber from the air inlet. It is the schematic cross section which showed the state. By removing the pressure applied to the cushion bag from the state shown in FIG. 5, the air chamber inflating material is expanded to expand the air chamber, and the air naturally flows from the air inlet to the air chamber.

FIG. 5 shows a state where air is applied by applying pressure to the cushion bag 10 with the air inlets IN _{1 to} IN ₅ opened to crush the air chambers 11 to 15 together with the air chamber inflating material 40 filled therein. the air present in the interior of the chamber 11 to 15 is a schematic sectional view showing a state where the exhaust from the air inlet iN ₁ to iN _5. 6 removes the pressure applied to the cushion bag 10 from the state shown in FIG. 5 to inflate the air chamber inflating material 40 to inflate the air chambers 11 to 15, and from the air inlets IN _{1 to} IN _5. It is the schematic cross section which showed the state which is making air flow naturally into the air chambers 11-15.

  As shown in FIG. 1, the pillow according to this embodiment includes a cushion bag 10 and a cover 20 for housing the cushion bag 10. The shape of the pillow is not particularly limited. In the pillow according to the present embodiment, the lower edge of the cushion bag 10 and the cover 20 (the edge on the side that supports the neck of the pillow user) is bent toward the upper edge of the cushion bag 10 and the cover 20. Forming. For this reason, the pillow is in the shape of a jade ball in plan view, the part supporting the neck of the pillow user is recessed on the upper edge side of the pillow, easy to follow the curve shape on the back of the pillow user's neck, The neck of the pillow user is not lifted too much. In addition, the cushion bag 10 has a lower left edge and a lower right edge (the part that bulges to the lower side of both sides of the lower edge) and supports the side of the neck of the pillow user from both sides to stabilize the neck. It is also possible to give a comfortable feeling of security to the pillow user. The dimensions of the pillow are not particularly limited, but in the pillow of this embodiment, the longitudinal length is 47 cm and the lateral length is 65 cm.

2. As shown in FIG. 2, the cushion bag 10 has an intermediate portion (point P ₁ , point P ₁₀ , point P ₁₂ , point P ₁₃ , point P ₅ , point P ₁₅ , point P ₁₄ , point P ₁₁ , inner space in part) that is surrounded by points P ₉ is a partitioned structure in a plurality of air chambers 11 to 15. In the pillow according to the present embodiment, the first air chamber 11 for supporting the central part of the back of the head of the pillow user, the second air chamber 12 for supporting the upper right part of the back of the head of the pillow user, and the use of the pillow A third air chamber 13 for supporting the upper left part of the back of the person's head, a fourth air chamber 14 for supporting the lower right part of the back of the head of the pillow user, and a lower left part of the back of the head of the pillow user The fifth air chamber 15 is partitioned. As shown in FIG. 2, an air chamber inflating material 40 is filled in the air chambers 11 to 15 in the cushion bag 10 (a region surrounded by a two-dot chain line in FIG. 2). On the other hand, the left edge (the part surrounded by the points P ₁₂ , P ₁₃ and P ₁₆ ) and the right edge (the part surrounded by the points P ₁₄ , P ₁₅ and P ₁₇ ) in the cushion bag 10 are shown. , A first solid chamber 16 and a second solid chamber 17, respectively. A solid cushion material 30 is accommodated in the solid chambers 16 and 17.

  The cushion bag 10 has, for example, a structure in which the internal spaces are partitioned into air chambers 11 to 15 and solid chambers 16 and 17 by joining separate bag bodies to each other (each bag body is an air chamber 11). To 15 or a structure forming solid chambers 16 and 17). However, in this case, it takes time and labor to join the bag body, and there is a possibility that the joining strength of the cushion bag 10 may be difficult. For this reason, the cushion bag 10 is formed in a bag shape by welding the peripheral edges of a sheet (usually a thermoplastic resin sheet) forming the upper surface side thereof and a sheet (usually a thermoplastic resin sheet) forming the lower surface side thereof. In this case, it is preferable that locations along the boundary between the air chambers 11 to 15 and the solid chambers 16 and 17 are also welded to each other. Thereby, the interior space of the cushion bag 10 can be partitioned into a desired shape by one welding molding, and the strength thereof can be increased.

The shapes of the air chambers 11 to 15 and the solid chambers 16 and 17 are not particularly limited. In the pillow of this embodiment, as shown in FIG. 2, the first air chamber 11 has a substantially pentagonal shape surrounded by points P ₃ , P ₄ , P ₅ , P ₆ , P ₇ . . The second air chamber 12 has a substantially rectangular shape surrounded by points P ₁ , P ₁₀ , P ₃ and P ₂ . Furthermore, the third air chamber 13 has a substantially rectangular shape surrounded by points P ₉ , P ₈ , P ₇ , P ₁₁ . Furthermore, the fourth air chamber 14 has a substantially triangular shape surrounded by points P ₄ , P ₁₃ , and P ₅ . The fifth air chamber 15 has a substantially triangular shape surrounded by points P ₆ , P ₅ , and P ₁₅ . Thereby, the air chambers 11-15 can be arranged compactly so that it can be easily adjusted to the height suitable for the pillow user. On the other hand, the first and second solid chambers 16 and 17 are substantially semicircular.

Further, as shown in FIG. 2, the first air chamber 11 is provided with a _first air inlet IN ₁ via a first air injection path 11a, which is indicated by arrows A ₁ and A ₂ . In this way, air can be introduced from the first air inlet IN ₁ to the first air chamber 11. Further, in the second air chamber 12, and a second air inlet IN ₂ is provided through the second air injection passage 12a, as indicated by the arrow B, the second air inlet IN ₂ To the second air chamber 12 can be introduced. Further, the third air chamber 13, and a third air inlet IN ₃ is provided via the third air injection passage 13a, as indicated by the arrow C, the third air inlet IN ₃ To the third air chamber 13 can be introduced. Furthermore, a fourth air inlet IN ₄ is provided in the fourth air chamber 14 via a fourth air injection path 14a, and as shown by an arrow D, the fourth air inlet IN ₄ is provided. Air can be introduced from ₄ to the fourth air chamber 14. Then, the fifth air chamber 15, the fifth and the fifth air inlet IN ₅ is provided via the air injection passage 15a, as indicated by the arrow E, the fifth air inlet IN ₅ To the fifth air chamber 15 can be introduced.

As described above, by independently providing the air injection ports IN _{1 to} IN ₅ and the air injection paths 11a to 15a for each of the air chambers 11 to 15, the amount of air to be injected can be independently set for each of the air chambers 11 to 15. By adjusting, it becomes possible to adjust the height of the pillow from place to place. When the pillow is used, the air inlets IN _{1 to} IN ₅ are closed by closing means (not shown) such as a stopper. In the pillow according to the present embodiment, the air inlets IN _{1 to} IN ₅ are closed with the same plug 18 (see FIG. 5 or FIG. 6) used for the air inlet of a floating ring or a vinyl pool. Yes.

As described above, the air chamber expansion material 40 filled in the air chambers 11 to 15 is not particularly limited as long as it is a porous elastic material having open air bubbles. However, in the pillow according to the present embodiment, a synthetic resin such as polyurethane is used. Adopting a foam molded sponge. Thus, by filling the air expansion member 40 to the air chamber 11 to 15, Guests blow into with a mouth air inlet IN ₁ to IN _5, without or connect the pump, the air chamber It becomes possible to supply air to 11-15. That is, as shown in FIG. 5, with the air inlets IN _{1 to} IN ₅ opened, pressure is applied by pressing the outer surface of the main body 10a of the cushion bag 10 by hand, etc. When squeezed together with the chamber expansion material 40, the air present in the air chambers 11 to 15 is discharged from the air inlets IN _{1 to} IN ₅ and, as shown in FIG. When air is removed, the air chamber expansion material 40 expands and the air chambers 11 to 15 also expand so that air naturally flows from the air inlets IN _{1 to} IN ₅ to the air chambers 11 to 15. Can do. Therefore, the height of the pillow can be easily adjusted for each place by a simple operation. In the example of FIGS. 5 and 6, the air injection passages 11 a to 15 a are not filled with the air chamber expansion material 40, but this portion may be filled with the air chamber expansion material 40 (air injection path expansion material). Good.

  The method for filling the air chamber inflating material 40 into the air chambers 11 to 15 is not particularly limited. For example, in a state where the air chamber inflating material 40 is arranged at the locations to be the air chambers 11 to 15, the sheet forming the upper surface side of the cushion bag 10 and the sheet forming the lower surface side are welded to each other. Although it is good, it is difficult when the air chamber expansion material 40 has a thickness. For this reason, it is preferable to insert the air chamber inflating material 40 after the sheets forming the upper surface and the lower surface of the cushion bag 10 are welded together to partition the internal space of the cushion bag 10 into the air chambers 11 to 15. Specifically, the cushion bag 10 is provided with an air chamber inflating material filling port, and after filling the air chamber inflating material 40 from the air chamber inflating material filling port, the air chamber inflating material filling port is closed by welding or the like. It is. Since the air chamber expansion material 40 can be compressed, the air chambers 11 to 15 can be filled without providing a large air chamber expansion material filling port. In addition, there is a method of filling the air chambers 11 to 15 with the uncured air chamber expansion material 40 from the air chamber expansion material filling port or the like using a nozzle or the like.

  The porosity of the air chamber expansion material 40 is not particularly limited, but if it is too small, it takes time for the air to reach the entire air chambers 11 to 15 when air is introduced into the air chambers 11 to 15. Become. For this reason, the porosity of the air chamber expansion material 40 is normally 50% or more. The porosity of the air chamber expansion material 40 is preferably 60% or more, more preferably 70% or more, and further preferably 80% or more. On the other hand, if the porosity of the air chamber expansion material 40 is too large, the elasticity of the air chamber expansion material 40 is weakened, and the air chambers 11 to 15 may not easily expand when air is introduced into the air chambers 11 to 15. There is. For this reason, the porosity of the air chamber expansion material 40 is normally 99% or less. The porosity of the air chamber expansion material 40 is preferably 98% or less, and more preferably 97% or less.

  The maximum height of the air chambers 11 to 15 (the height of the air chambers 11 to 15 when the air chamber expansion material 40 is expanded to the limit inside the air chambers 11 to 15) is not particularly limited. However, if the maximum height of the air chambers 11 to 15 is too low, the range in which the height of each part of the pillow can be adjusted becomes narrow. For this reason, the maximum height of the air chambers 11 to 15 is usually 20 mm or more. The maximum height of the air chambers 11 to 15 is preferably 30 mm or more, and more preferably 40 mm or more. On the other hand, making the maximum height of the air chambers 11 to 15 too high does not make much sense for the use of the pillow. For this reason, the maximum height of the air chambers 11 to 15 is set to 100 mm or less.

The arrangement of the air injection ports IN _{1 to} IN ₅ and the air injection paths 11a to 15a is not particularly limited. In the pillow according to the present embodiment, as shown in FIG. 2, the air inlets IN _{1 to} IN ₅ are collectively arranged on the projecting piece 10 b provided in a strip shape along the upper edge of the main body 10 a of the airbag 10. ing. The first air inlet IN ₁ is in central protrusion 10b, the second air inlet IN ₂ is the first left air inlet IN ₁ in projecting piece 10b, a third air inlet IN ₃ is the right side of the first air inlet IN ₁ in the projecting piece 10b, and the fourth air inlet IN ₄ is the fifth air on the left side of the second air inlet IN ₂ in the projecting piece 10b. The inlet IN ₅ is provided on the right side of the third air inlet IN ₃ in the projecting piece 10b. The first air injection path 11a is between the second air chamber 12 and the third air chamber 13, and the fourth air injection path 14a is the first air chamber 11 and the second air chamber. On the left side of 12, the fifth air injection path 15a is provided on the right side of the first air chamber 11 and the third air chamber 13, respectively. The second air injection passage 12a is in the form of directly with the second air inlet IN ₂ and a second air chamber 12, the third air injection passage 13a is provided with a third air inlet IN ₃ first The three air chambers 13 are provided so as to be directly connected.

Of the air injection passage 11A～15a, first air injection passage 11a, as shown in FIG. 2, the width is wider brought from the first air inlet IN ₁ approaches the first air chamber 11 ( the distance between the point P ₂ and the point P ₈ is formed so as to become longer) than the distance between the point P ₁ and point P _9. And the lower end center part in the 1st air injection path 11a is made into the adhering part 11b to which the upper surface and lower surface of the cushion bag 10 were mutually adhering. For this reason, it is possible to support at a low position from the center part of the back of the head of the pillow user to the upper part of the back of the head so that the vicinity of the center in the middle part of the cushion bag 10 is the lowest. The fixing portion 11b may be provided by bonding the upper surface and the lower surface of the cushion bag 10 to each other. In the pillow according to the present embodiment, when the predetermined space on the upper surface and the lower surface of the cushion bag 10 is welded to each other to partition the internal space of the cushion bag 10 into the plurality of air chambers 11 to 15 and the solid chambers 16 and 17, The lower end central portion of the air injection path 11a is also welded to provide the fixing portion 11b. Thereby, the adhering part 11b can be formed efficiently. The air introduced from the first air inlet IN ₁ is divided into two near the lower end of the first air introduction path 11a and introduced into the first air chamber 11 as indicated by arrows A ₁ and A _2. Is done.

  The cushion material 30 filled in the solid chambers 16 and 17 is filled from the first cushion material filling port 16a and the second cushion material filling port 17a provided in the first solid chamber 16 and the second solid chamber 17, respectively. Is done. The cushion material filling ports 16a and 17a have a structure that can be closed by a fastener or the like. Examples of the cushioning material 30 accommodated in the solid chambers 16 and 17 include granular materials such as beads, pipe chips and buckwheat husks, fibrous materials such as cotton and feathers, and lump materials such as a mat made of low-rebound polyurethane foam. Is done. In the pillow of this embodiment, a large number of beads are accommodated in the solid chambers 16 and 17 as cushion materials 30. For the beads used as the cushion material 30, resin particles such as polyethylene, polypropylene, and polyurethane, or foamed resin particles obtained by foaming these resins are usually used.

The particle size of the beads used as the cushion material 30 is not particularly limited, too small, there is a possibility that cushions member 30 is likely to leak from the cushioning material filling port 16a, 17a. For this reason, the particle size of the beads used as the cushioning material 30 is usually 0.1 mm or more. The particle size of the beads used as the cushion material 30 is preferably 0.3 mm or more, and more preferably 0.5 mm or more. On the other hand, when the particle size of the beads used as the cushion material 30 is too large, the feel of the left and right edges of the pillow may be deteriorated. For this reason, the particle size of the beads used as the cushion material 30 is usually 5 mm or less. The particle size of the beads used as the cushion material 30 is preferably 4 mm or less, and more preferably 3 mm or less.

  The height of the left and right edges of the cushion bag 10 where the solid chambers 16 and 17 are provided (the cushion material 30 is accommodated in the solid chambers 16 and 17 and the cushion bag 10 is not loaded) As shown in FIG. 3, the thickness of the highest place at the time (the same applies hereinafter) is made higher (thicker) than the middle portion of the cushion bag 10 where the air chambers 11 to 15 are provided. Thereby, a pillow user's head can be held in the middle part of a pillow. The height (thickness) of the left edge portion and the right edge portion of the cushion bag 10 is normally the height of the middle portion of the cushion bag 10 (the height (thickness) of the highest (thickness) portion. The same applies hereinafter). .)) By 10 mm or more. The left edge and the right edge of the cushion bag 10 are preferably 15 mm or more higher than the middle part, and more preferably 20 mm or more. On the other hand, if the left edge and the right edge of the cushion bag 10 are too high, the pillow user may feel a sense of restraint on the head. For this reason, the left edge part and the right edge part of the cushion bag 10 are normally set not to be higher than the middle part by 50 mm or more, preferably 40 mm or more.

3. As shown in FIG. 1, the cover 20 is for accommodating the cushion bag 10 inside, and is for improving the breathability and touch of the pillow. The cover 20 has a bag shape that follows the cushion bag 10, and has a size slightly larger than that of the cushion bag 10. The cushion bag 10 is configured to be inserted into the cover 20 from a cushion bag insertion opening (not shown) provided on the lower surface side of the cover 20. Various materials used for a general pillow cover can be used for the cover 20. The cover 20 may be entirely formed of the same material. However, as shown in FIG. 4, the left edge 22 (portion shown by hatching) and the right edge 23 ( The portion (indicated by hatching) is softer than the intermediate portion 21 (portion surrounded by the points Q ₁ , Q ₅ , Q ₃ , Q ₆ , Q ₈ , Q ₄ , Q ₇ ) on the upper surface thereof. It may be formed of a material having a small degree. Thereby, while making it easy to transmit the feeling of the cushion material 30 with which the solid chambers 16 and 17 were filled, it can make it hard to transmit the feeling of creaking of the air chambers 11-17.

Further, as shown in FIG. 4, on the upper surface of the intermediate portion 21 of the cover 20, a mark (dashed line Q ₁ Q in FIG. 4) for indicating the shape of the air chambers 11 to 15 in the cushion bag 10 (see FIG. 2). ₂ , broken line Q ₂ Q ₃ and broken line Q ₂ Q ₄ ). Among these marks, broken lines Q ₁ Q ₂ are provided along the center of the air injection path 11 a in the cushion bug 10 (the boundary between the second air chamber 12 and the third air chamber 13). Also, the broken line Q ₂ Q ₃ and the broken line Q ₂ Q ₄ indicate the line segment P ₃ P ₇ (the boundary between the first air chamber 11 and the second air chamber 12 and the first air chamber 11 and the It is provided along the boundary of the third air chamber 13). For this reason, when injecting air into the air chambers 11 to 15, it is possible to easily recognize from the outside of the cover 20 which air chamber is high in which range. These marks may be provided by printing on the outer surface of the cover 20, but the marks may be provided by forming a seam in the intermediate portion 21 of the cover 20.

4). Others The middle part of the cushion bag 10 (enclosed by point P ₁ , point P ₁₀ , point P ₁₂ , point P ₁₃ , point P ₅ , point P ₁₅ , point P ₁₄ , point P ₁₁ , point P ₉ in FIG. 2) A cushion mat (not shown) having a planar shape following the portion) may be accommodated in the cover 20 in a state of being overlaid on the upper surface of the intermediate portion of the cushion mat 10. Thereby, the touch of the intermediate part of the cushion bag 10 can be made harder to be transmitted to the back of the pillow user.
