Description

The present invention relates to a pillow in which a plurality of rod-shaped member groups are arranged inside a pillow body.

Pillows are bedding that greatly affect the quality of sleep. It is said that the weight of a human head is about 5 kg on average, and if the pillow is made flexible and the amount of sinking is deepened, the repulsive force will be insufficient, and the weight of the head will put an excessive burden on the neck, making it comfortable to sleep. It will be damaged. On the other hand, if the pillow is hardened to increase the repulsive force, the amount of subduction is insufficient, and the feeling of discomfort to the occipital region and the temporal region is increased, resulting in impaired sleeping comfort.
Therefore, by adjusting the amount of sinking of the pillow and the repulsive force according to the preference of the user, the sleeping comfort can be improved and the quality of sleep can be improved.

In Patent Document 1, a pillow body made of a soft elastic foam resin material and a lower portion inside the pillow extend along the horizontal direction of the pillow and are arranged in parallel along the vertical direction of the pillow. A pillow with four round bar-shaped plugs and is described.
In the pillow described in Patent Document 1, a plurality of types of plugs having different hardness are prepared in advance, and the hardness of the pillow can be adjusted by the user selecting and exchanging the plugs.

Special Table 9-511670 Gazette

In the pillow of Patent Document 1, when the head is placed on the upper surface of the pillow, the downward load due to the weight of the head is received by the flexible pillow body and the individual plugs, so that the weight of the head is heavy. It is necessary to increase the hardness of the plug to counteract the problem.
If the hardness of the plug is increased, when the head is placed on the upper surface of the pillow, the hardness of the plug increases the feeling of pressure (uncomfortable feeling) on the back of the head and the temporal region, which impairs the comfort of sleeping.
The present invention has been made in view of such circumstances, and an object of the present invention is to improve sleeping comfort.

In order to solve the above problems, the pillow according to the present invention is formed by an elastic body and has a pillow body on which the user's head is placed on the upper surface, and within a first height range inside the pillow body. A group of first rod-shaped members composed of a plurality of first rod-shaped members arranged in parallel, and a plurality of members arranged in parallel in a second height range different from the first height range inside the pillow body. A second rod-shaped member group composed of the second rod-shaped member, and the plurality of second rod-shaped members are arranged so as to intersect with the plurality of first rod-shaped members in a plan view. The first rod-shaped member and the plurality of second rod-shaped members are made of a material harder than the pillow body, and a load due to the weight of the head is applied to the first rod-shaped member and the second rod-shaped member. It is characterized in that it is dispersed and supported at the intersection of the rod-shaped members.

According to the pillow according to the present invention, the sleeping comfort can be improved.

<Characteristics of pillow 1A according to the first embodiment>
The pillow 1A shown in FIGS. 1 and 2 is arranged in parallel with, for example, a pillow body 11 formed of an elastic body made of foamed resin and an upper portion 11U (first height range) inside the pillow body 11. Within the first rod-shaped member group 22 composed of the plurality of first rod-shaped members 21A and the lower portion 11L (second height range different from the first height range) inside the pillow body 11. A second rod-shaped member group 32 composed of a plurality of second rod-shaped members 31A arranged in parallel is provided. The first rod-shaped member group 22 and the second rod-shaped member group 32 are arranged at a slight interval (for example, an interval of about 1 cm to 3 cm) in the vertical direction. In other words, a part of the pillow body 11 is interposed between the first rod-shaped member group 22 and the second rod-shaped member group 32.
As will be described later, each of the first rod-shaped members 21A (21a to 21c, see FIG. 3A) and each second rod-shaped member 31A (31a to 31c, see FIG. 3B) are, for example, , Wood, resin, and metal, which are harder than the pillow body 11.

The plurality of second rod-shaped members 31A are arranged so as to intersect the plurality of first rod-shaped members 21A in a plan view. Therefore, as shown in FIG. 4, when the user's head HD is placed on the upper surface of the pillow 1A, a downward load is applied to the pillow 1A due to the weight of the head HD. In FIG. 4, the magnitude of the load is represented by the diameter of the circle.
As can be understood from the diameter of the circle, the downward load applied to the pillow 1A is larger in the portion closer to the head HD. Therefore, the plurality of first rod-shaped members 21A bend downward about the portion facing the head HD due to the downward load.

As the plurality of first rod-shaped members 21A bend, the plurality of second rod-shaped members 31A located below the plurality of first rod-shaped members 21A receive a load. In other words, the downward load due to the weight of the head HD is received by the plurality of first rod-shaped members 21A and the plurality of second rod-shaped members 31A. Since each of the first rod-shaped members 21A and each second rod-shaped member 31A functions as a load propagation member and intersects with each other in a plan view, the load is applied to each of the first rod-shaped members 21A and each of the second rod-shaped members 21A. The rod-shaped member 31A of the above is dispersed and received.
By distributing the load, the feeling of pressure given to the head HD is reduced, so that the sleeping comfort can be improved.
