Description

  The present invention relates to a pillow that is used when sleeping, etc., and has excellent fit, breathability, and cushioning properties.

  Pillows support the head and neck during sleep, and conventionally, pillows of various shapes and materials have been used to provide comfort and promote health. Among them, as a typical pillow, a double-hump-shaped pillow using a synthetic resin foam as shown in Patent Document 1 has been proposed.

Japanese Patent Laid-Open No. 7-163448

  This double-hump pillow has two wave-shaped peaks in the depth direction, and this shape fits an S-shaped line from the person's neck to the back of the head. However, the shape of the person's neck and occipital area varies greatly, and the shape of this S-shaped line varies from person to person. There is a problem that it is difficult to fit everyone.

  In general, cushioning is made by using the material function of the pillow itself, such as synthetic resin foam, or by using a composite material (such as a filling or spring of another material), but the material function itself is used. There is a limit to the cushioning property, and there is a problem that the structure using a composite material becomes complicated and the cost increases. In addition, pillows using synthetic resin foam have poor breathability and have the disadvantage of causing sweat to accumulate in the summer and making the user feel uncomfortable.

  The present invention has been made in view of the above-described problems, and the object of the present invention is a pillow that has a simple structure and is excellent in breathability and cushioning, and can fit everyone and sleep comfortably. Is to provide.

  In order to solve such a problem, the pillow of the present invention has a pillow core material (pillow core material 2) formed of a single material having elasticity of a synthetic resin foam, as described in claim 1. A plurality of convex portions (convex portions 7) projecting in a column shape in the lateral direction on the front side of the pillow core material (pillow core material 2), and the convex portions (convex portions) A plurality of concave portions (concave portions 8) provided in a groove shape in parallel with the convex portions (convex portions 7) between the portions 7) and a single raised in a mountain shape provided in a portion where the neck portion is placed The gist is that a hollow portion (cavity portion 10) penetrating in the lateral direction is formed below the hump portion (hump portion 9).

  That is, in the pillow of the present invention, the portion that contacts the neck portion is only a single hump portion provided on the front side of the pillow core material, and a hollow portion is provided under the hump portion. Therefore, when the neck is placed on the hump and a load is applied, the cavity is flexibly interlocked with the neck and holds the S-shaped line from the neck to the back of the head.

  Furthermore, almost the entire front surface of the pillow core material is provided with a convex portion and a concave portion, so that the surface side is softer than the lower layer even though the pillow core material is formed of a single material. It is a two-stage layer, and the lower layer is more elastic than the front layer. Therefore, when the neck and the head are placed on the pillow, in the surface layer, the convex portion receives the neck and the head and is distorted into the concave portion 8 space, while suitably distributing the pressure of the neck and the head, Firmly support the neck and head with the lower layer.

  In the pillow of the present invention configured as described above and acting in this way, it is possible to fit the S-shaped line when used regardless of the shape of the neck and the back of the head that are different from person to person. . As a result, there is a remarkable effect that it is possible to relax the neck muscles (beveled muscles) that fits all people and is difficult to massage and provide comfortable sleep.

  Moreover, the pillow of this invention can take out the outstanding cushioning property by simple structure at low cost by the effect | action of a cavity part, a convex part, and a recessed part, without using a composite material. Moreover, since the lower layer is a two-stage layer that has greater elasticity than the surface layer, it does not sink excessively when the neck and head are placed, and it is possible to provide an appropriate cushioning property. It becomes.

  In addition, it is difficult for moisture to accumulate due to the hollow portion, and furthermore, the concave portion prevents heat from being trapped between the neck and the head and the pillow, so that even if the material is a synthetic resin foam, it is extremely breathable. It becomes possible to provide a good pillow. That is, it is possible to ensure excellent air permeability while fully utilizing the elastic force of the synthetic resin foam.

  Here, the structure of the pillow core material may be further improved as follows. That is, the pillow according to claim 2 is the pillow according to claim 1, wherein the pillow core material (pillow core material 2) extends downward from the hollow portion (hollow portion 10) and the pillow core material (pillow) The gist is that it has a cut surface (cut 6a) reaching the back surface of the core material 2).

  Therefore, in the pillow of the present invention configured as described above, when the neck and head are placed on the pillow and a load is applied, the cut surface moves accordingly, so that the cavity easily contracts. With a simple structure, the cushioning property can be further improved at low cost.

It is a whole perspective view of the pillow 1 concerning this embodiment. It is a side view of the pillow 1 concerning this embodiment. It is a side view which shows the use condition of the pillow 1 concerning this embodiment.

<1. Configuration of pillow 1>
Below, embodiment concerning the pillow 1 of this invention is described based on drawing. First, the configuration of the pillow 1 will be described. FIG. 1 is an overall perspective view of the pillow 1, and FIG. 2 is a side view of the pillow 1. The pillow 1 is composed of a pillow core material 2 that is formed in a horizontally long rectangular shape when viewed in plan and a cover body 3 indicated by a two-dot chain line that covers the pillow core material 2.

  As shown in FIGS. 1 and 2, the pillow core material 2 has a shape in which one sheet is folded in half, and is formed in a substantially “tsu” shape when viewed from the side. In FIG. 2, the left (head side) pillow head 4 is gently curved upward as the lower surface thereof becomes the head side, and is formed into a thick shape, while the right (neck side) pillow neck 5 is The bent portion 6 has a bent portion 6 that is approximately half the thickness of the pillow head portion 4, and the bent portion 6 is formed so as to be curved more greatly than the lower surface of the pillow head portion 4 as its lower surface becomes the neck side. ing.

  As shown in FIG. 1, a plurality of horizontal semi-cylindrical convex portions 7 are provided over the entire surface of the pillow core material 2, and a horizontal groove shape is formed between these convex portions 7. The recess 8 is provided. Further, the surface of the pillow core material 2 is gradually inclined upward from the pillow head 4 toward the pillow neck 5 due to the curved shape of the lower surface of the pillow head 4 and the pillow neck 5 described above. The opposite part of the part 6 forms a hump part 9 that rises like a mountain.

  In the figure, 6a is a cut which becomes the tip of the bent portion 6, and this cut 6a has a cut surface formed in an inclined surface so that its lower edge 6b matches the lower edge 4a of the pillow head 4. In addition, the back surface of the pillow head 4 is abutted in a series. When the cut 6 a comes into contact with the back surface of the pillow head 4, a hollow portion 10 having a substantially elliptical shape in a side view is formed between the hump portion 9 and the bent portion 6 in the pillow neck portion 5.

  The pillow core material 2 is formed of an elastic material such as a synthetic resin foam having cushioning properties. For example, soft synthetic materials such as soft polyurethane, polyethylene, polypropylene, polyvinyl chloride, ethylene vinyl acetate copolymer, and rubber are used. A resin foam is mentioned. Note that these soft synthetic resin foams may be combined with chemical fiber cotton such as nylon, polyester, and acrylonitrile, and natural fiber cotton such as cotton, hemp, palm rock, and wool to form the pillow core material 2.

<2. Effect of Pillow 1>
Since the pillow 1 of the present invention is configured as described above, when it is used, as shown in FIG. And since the cavity part 10 is provided under the hump part 9, when the neck part rests on the hump part 9 and a load is applied by this, the cavity part 10 will become a neck like an air spring. In addition, it interlocks flexibly and holds an S-shaped line (hereinafter also simply referred to as “S-shaped line”) from the neck to the back of the head.

  Furthermore, the surface side of the pillow core material 2 is a softer layer than the lower layer due to the convex portions 7 and the concave portions 8, that is, the pillow core material 2 is a surface regardless of a single material. Is a two-stage structure with a soft “soft layer” and a solid “solid layer” below, and each has a different elastic force (the “hard layer” has a larger elastic force than the “soft layer”). As a result, when the neck and head are placed on the pillow 1, the convex portion 7 receives the neck and head, and is distorted into the recess 8 space formed between the convex portions 7, thereby reducing the pressure of the neck and head. While being preferably dispersed by the “soft layer”, the neck and the head are firmly supported by the “solid layer” on the lower side of the convex portion 7 and the concave portion 8. FIG. 3 is a side view showing the usage state of the pillow 1.

  With the lump-shaped pillow 1 of the present invention acting in this way, when the neck and head are placed, the back of the head fits snugly along the inclination of the pillow head 4 (gradual downward inclination toward the top of the head). The neck fits snugly along the mountain shape of the hump 9. That is, even if the S-shaped line is different from person to person, the pillow 1 of the present invention is like the above-mentioned two-hump-shaped pillow, and the top of the back of the head is caught on the head-side hump. There is no inconvenience that a gap is formed in the occipital region, that is, it is possible to fit the S-shaped line exactly regardless of the shape of each person's neck or occipital region. Therefore, there is a remarkable effect that it is possible to relax the neck muscles (oblique muscles) that fits all people and is difficult to loosen and provide comfortable sleep.

  Moreover, the pillow 1 of the present invention is excellent in a simple configuration at a low cost without using a composite material (a filling material or a spring of other materials) due to the action of the hollow portion 10 and the convex portion 7 and the concave portion 8. Cushioning can be achieved. In addition, when the neck and head are placed on the pillow 1 and a load is applied, the cut 6a (particularly, the lower edge 6b side of the cut 6a) that is in contact with the pillow head 4 is separated from the pillow head 4 and the cavity Since 10 becomes easy to shrink, cushioning properties are further improved. In addition, the two-stage structure of “soft layer” and “solid layer” does not sink excessively when the neck and head are placed, and can provide an appropriate cushioning property.

  In addition, the hollow portion 10 makes it difficult for moisture to accumulate, and the concave portion 8 prevents heat from being trapped between the neck and head and the pillow 1, thereby providing a pillow 1 with extremely good ventilation, As a result, even when a synthetic resin foam is used as the material for the pillow core material 2, it is possible to prevent the user from becoming uncomfortable due to sweat accumulation in summer.

  As mentioned above, although the pillow 1 of this invention has been demonstrated based on drawing, a concrete structure is not limited to what was shown in embodiment, The change in the range which does not deviate from the summary of this invention, an addition, etc. Even if it is, it is included in the present invention. For example, in the above-described embodiment, the hollow portion 10 may be formed in the pillow core material 2 so as to be cut out later, and the cut 6a may be eliminated. In this case, there may be a plurality of hollow portions 10.

  Moreover, although the convex part 7 and the recessed part 8 are provided in the surface of the pillow core material 2 of embodiment mentioned above over the whole surface, not only this but the area | region except the part along right and left both ends, The convex part 7 and the recessed part 8 may be provided in the area | region except the part along the edge part by the side of the pillow head 4 side. Even in such a case, the same effect can be obtained.
