Description

  The present invention relates to a pillow and a cushion structure that elastically supports a user's head during sleep.

  The pillow used at the time of sleep is required to have a function of giving a soft touch to the user's head and supporting it comfortably, a function of supporting the head in a stable state, and the like.

  Conventionally, pillows having various configurations have been developed to provide the above-described functions. For example, Patent Document 1 discloses a pillow having a structure in which sheet-like urethane foam is laminated in three layers. The lower urethane foam is for adjusting the height of the entire pillow, and the height of the pillow is adjusted by increasing or decreasing the number as necessary.

  The uppermost urethane foam has a large number of irregularities on the upper surface so that moisture can be released easily.Furthermore, a foam with a lower foam density than the intermediate urethane foam, that is, a urethane foam that is harder to touch than the intermediate urethane foam is used. Yes.

  Film-free urethane foam is used for the upper and middle urethane foams to ensure air permeability. Then, the polymerized three-layer urethane foam is accommodated in a bag body formed of a knitted fabric whose upper surface side has air permeability.

  According to the pillow having such a configuration, it has excellent breathability and the upper urethane foam is soft, so that it can be fit and supported firmly from the user's head to the neck.

  The pillow shown by patent document 2 accommodates the cushion material in the inner bag body which has air permeability, arrange | positions the polyester cotton as a filler around the interior body, and the said cushion material covered with the said filler Is housed in an exterior bag.

  The cushion material is sandwiched between a plurality of breathable fabrics in a state where a large number of springs are aligned, and each spring is folded in a meandering manner in an individually encased state. It adheres and it accommodates in the said interior body.

  As a result, when the head or cervical vertebra is placed on the upper surface of the pillow, the built-in spring deforms against the elastic force, and when the head or cervical vertebra is removed from the upper surface, the spring quickly returns to its original state. Since it is easy to return, the air permeability is good. In addition, since the material for encasing the spring and the interior bag are materials having air permeability, the overall air permeability can be improved by this, and moisture and heat can be quickly dissipated.

  By the way, according to the pillow shown in Patent Document 1, a number of irregularities are formed on the upper surface of the upper urethane foam, and the irregularities are formed by using a film-free urethane foam having air permeability for the upper and intermediate urethane foams. And the air permeability of the non-film urethane foam may make it difficult to keep moisture.

  However, since moisture enters the inside of the upper and middle urethane foam from the surface of the pillow, the moisture that has entered the inside of the urethane foam may be difficult to escape to the outside. That is, since moisture tends to stay inside the pillow, comfort may be reduced.

  Moreover, since the urethane foam is simply laminated in three layers, the urethane foam is elastically deformed depending on the weight of the head, and the head may easily sink into the inside. Therefore, not only can the user's head not be supported in a stable state with a moderate hardness, but also the laminated urethane foam is generally compressed and deformed, and it is difficult to ensure sufficient air permeability. is there.

  According to the pillow disclosed in Patent Document 2, a large number of springs are used as the cushion material. Therefore, it is possible to improve the air permeability as compared with the case where the entire pillow is constituted by a plurality of laminated urethane foams, and it is also possible to support the user's head with a moderate hardness by the cushioning property of the spring. It becomes possible.

  However, when a spring is used for the pillow, the spring is formed of a hard wire such as steel. For this reason, the hardness of the spring is easily transmitted to the user's head, which may impair comfort.

  In order not to transmit the hardness of the spring to the user's head, the filler covering the inner bag must be thickened. However, thickening the filler may not only reduce the breathability of the pillow, but may also increase the overall thickness more than necessary.

  In other words, a cushion material using a spring formed of a hard material such as a wire is considered suitable for use as a sofa cushion, but sufficient comfort cannot be obtained when used as a pillow. There is.

  An object of the present invention is to provide a pillow and a cushion structure capable of providing good cushion performance and air permeability without using a hard material such as a wire.

This invention is a pillow having an exterior body formed into a bag shape with a fabric having air permeability and a cushion body accommodated in the exterior body,
The cushion body is formed in a cylindrical shape having a vent hole penetrating in the vertical direction by an elastic material, and a plurality of intermediate support members having reinforcing convex portions provided over the entire length in the circumferential direction are arranged in a matrix on the outer peripheral surface. The pillow is characterized by being formed.

This invention is a cushion structure having an exterior body formed into a bag shape by a fabric having air permeability and a cushion body accommodated in the exterior body,
The cushion body is formed in a cylindrical shape having a vent hole penetrating in the vertical direction by an elastic material, and a plurality of intermediate support members having reinforcing convex portions provided over the entire length in the circumferential direction are arranged in a matrix on the outer peripheral surface. It is in the cushion structure characterized by being formed.

  Since the intermediate support member which comprises a cushion body has a vent hole penetrated to an up-down direction, the air permeability of the whole pillow is improved.

  In addition, since the reinforcing protrusions are provided on the outer peripheral surface over the entire length in the circumferential direction, when the intermediate supporting member is elastically compressed and deformed by the load on the user's head, the reinforcing protrusions are resistant to compressive deformation. In addition to exhibiting moderate hardness, the reinforcing projections can support the user's head with stability in order to prevent the intermediate support member from bending in the middle in the height direction. .

Thereby, the cushion body 3 can be taken in and out of the exterior body 2.

  The lower layer member 5 of the cushion body 3 is formed in a rectangular plate shape by urethane foam as an elastic material.

  The lower layer member 5 may be formed using a material such as an elastic material such as synthetic rubber, expanded polystyrene, three-dimensional mesh, soft resin, or hard resin.

  As shown in FIGS. 4 (a) and 4 (b), the intermediate support member 6 is formed by laminating two piece members 11 formed in a abacus ball shape with urethane foam as an elastic material in the vertical direction, It is integrally formed by means.

  That is, the intermediate support member 6 in which the two piece members 11 are laminated has a cylindrical shape having a vent hole 12 penetrating in the vertical direction as a whole, and has a triangular cross-sectional reinforcement over the entire length in the height direction. A convex portion 13 is formed over the entire circumferential length of each piece member 11.

  Since the reinforcing protrusions 13 are provided over the entire length in the height direction of each piece member 11, the two reinforcing protrusions 13 are vertically arranged on the reinforcing protrusion 13 in which the two piece members 11 are stacked in the vertical direction. It is provided in a state of being connected without gaps in the direction.

  When the lower layer member 5 is formed of urethane foam as an elastic material, the intermediate support member 6 is formed of an elastic material such as urethane foam that is equal to or softer than the lower layer member 5. .

  The intermediate support member 6 is formed by laminating and bonding the two piece members 11 in the vertical direction, but may be integrally formed without being divided into the two piece members 11. Moreover, although the said intermediate | middle support member 6 was formed with urethane foam, you may make it form with other elastic materials, such as soft resin and rubber | gum. In addition, the reinforcing convex portion 13 provided on the outer peripheral surface of the intermediate support member 6 has a triangular cross section, but the sectional shape of the reinforcing convex portion 13 is a semicircular shape, a semi-elliptical shape, a trapezoidal shape, or the like. Any cross-sectional shape may be used as long as the height dimension on the tip side is smaller than the end side.

  The plurality of intermediate support members 6 are arranged in a matrix with their lower surfaces adhered to the upper surface of the lower layer member 5. As shown in FIGS. 1 to 3, the intermediate support member 6 has a reinforcing protrusion 13 on the outer peripheral surface in the row direction of the cushion body 3 (longitudinal direction of the cushion body 3) as shown in FIGS. 1 and 2. It arrange | positions at the space | interval which the gap | interval g produces between, and is arrange | positioned in the row direction (short side direction of the cushion body 3), as shown in FIG. 1 and FIG.

  The intermediate support member 6 may be disposed in contact with the reinforcing protrusions 13 in both the row direction and the column direction, or may be disposed so that a gap g is generated between the reinforcing protrusions 13 in both directions. Also good.

  The upper layer member 7 is provided on the upper surface of the intermediate support member 6 arranged in a matrix with the lower surface bonded. The upper layer member 7 is formed by a low resilience urethane foam, which is an elastic material, in the form of a sheet having the same planar shape as the lower layer member 5, and the upper surface of the user U's head H as shown in FIG. And the convex part 16 which supports the neck N of the user U are formed.

  The upper layer member 7 is made of low-resilience urethane foam, but may be made of other elastic material such as soft resin or three-dimensional mesh.

  The lower surface of the intermediate support member 6 and the upper surface of the lower layer member 5, and the upper surface of the intermediate support member 6 and the lower surface of the upper layer member 7 are joined and fixed by other means such as welding without being bonded. You may do it.

  As shown in FIG. 1, the lower layer member 5 and the upper layer member 7 are provided on the upper surface side of the upper layer member 7 and between the lower layer member 5 and the upper layer member 7 provided with the intermediate support member 6. A plurality of first ventilation holes 5a and 7a communicating with the space 18 are respectively formed in a matrix.

  Further, the lower layer member 5 and the upper layer member 7 are provided with second vent holes 5b having a diameter larger than that of the first vent holes 5a and 7a at positions corresponding to the vent holes 12 of the intermediate support member 6. 7b is drilled. That is, the second vent holes 5 b and 7 b communicate with the vent hole 12.

  The cushion body 3 formed by integrating the lower layer member 5, the intermediate support member 6 and the upper layer member 7 opens the fastener 8 provided on the outer peripheral surface of the exterior body 2 and is accommodated therein. ing.

  According to the pillow 1 configured as described above, when the user U puts the head H on and uses it as shown in FIG. 5, the user U has the softness of the low-resilience urethane foam formed with the upper layer member 7. The head portion H and neck portion N are supported in a stable state by the concave portion 15 and the convex portion 16 formed in the upper layer member 7 with cushioning properties and in a good feeling.

  The load on the head U of the user U is transmitted from the upper layer member 7 to the intermediate support member 6 arranged in a matrix, and the head H of the user U is elastically supported by the intermediate support member 6. become. When a load is applied to the intermediate support member 6, the two piece members 11 forming the intermediate support member 6 are elastically deformed in the compression direction.

  Although each piece member 11 is formed in a cylindrical shape, a reinforcing convex portion 13 having a triangular cross section is formed over the entire length on the outer peripheral surface. Therefore, even if each piece member 11 is cylindrical, the reinforcing projection 13 is bent with respect to the direction intersecting the axial direction, or the piece 12 is halfway in the height direction and the vent hole 12 is formed in the middle. Prevents elastic deformation in the spreading direction.

  Thereby, the intermediate support members 6 arranged in a matrix form are reliably elastically deformed in the axial direction while generating a repulsive force against the load, that is, a spring action, by receiving the load of the user's head H. The user's head H will be supported with moderate hardness and stability.

  The plurality of intermediate support members 6 are arranged in a matrix, and the intermediate support members 6 adjacent to each other in one direction are arranged in contact with reinforcing convex portions 13 formed on the outer peripheral surface. Therefore, when the intermediate support member 6 brought into contact with the outer peripheral surface is compressed and deformed under a load, it is difficult to incline in the direction intersecting the axial direction, and this also supports the user's head H in a stable state. Will do.

  Since the intermediate support members 6 are arranged in a matrix, the space 18, that is, the cushion body 3 has air permeability. For this reason, it may be difficult for the cushion body 3 to accumulate moisture.

  In addition, the lower layer member 5 and the upper layer member 7 communicate with the first communication holes 5 a and 7 a communicating with the space 18 in which the intermediate support member 6 is provided, and the vent hole 12 of the intermediate support member 6. Second communication holes 5b and 7b are formed.

  Therefore, the first communication holes 5 a and 7 a prevent moisture from being trapped in the space 18, and the second communication holes 5 b and 7 b trap moisture in the air holes 12 of the intermediate support member 6. Is prevented.

  Since the second communication holes 5b and 7b are larger in diameter than the first communication holes 5a and 7a, the second communication holes 5b and 7b communicating with the upper and lower sides of the vent hole 12 of the intermediate support member 6 are respectively provided. Even with one, good air permeability can be obtained.

  In addition, moisture that has entered the space 18 and the ventilation holes 12 of the intermediate support member 6 is easily discharged to the outside through the first and second communication holes 5a, 7a and 5b, 7b. Therefore, moisture is prevented from entering and remaining inside the lower layer member 5, the intermediate support member 6, and the upper layer member 7 formed of urethane foam, and thus the cushion body 3 may be less susceptible to moisture. .

  The other directions of the plurality of intermediate support members 6 arranged in a matrix are arranged with a predetermined gap g. Therefore, the air permeability of the space portion 18 in which the intermediate support member 6 is disposed can be improved by the gap g, so that it is possible to prevent the cushion body 3 from being dampened.

  In the above-described embodiment, the first communication holes 5a and 7a and the second communication holes 5b and 7b are formed in the lower layer member 5 and the upper layer member 7, respectively. The communication holes 5 a and 5 b are formed and may not be formed in the lower layer member 5. Even in such a case, it is possible to prevent moisture from being accumulated in the cushion body 3.

  Although the intermediate support member 6 is formed by two piece members 11, it may be formed by three or more piece members 11, and when the intermediate support member 6 is configured without being divided into a plurality of piece members, You may make it provide one or three or more reinforcement convex parts provided in an outer peripheral surface.

  The lower layer member 5 and the upper layer member 7 are provided with the second communication holes 5b and 7b communicating with the vent hole 12 of the intermediate support member 6, but the second communication holes 5b and 7b may not be provided. When the second communication holes 5b and 7b are provided, the second communication holes 5b and 7b may be the same size as the first communication holes 5a and 7a.

  In the above-described embodiment, the case where the cushion body 3 as the cushion structure body is used as a pillow has been described. However, the cushion body 3 may be used for a cushion structure body such as a mattress or a sofa.
