Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a pillow having a height adjusting function.

[0002]

[Prior art]

 Conventionally, a pillow in which a filling material such as a granular material is enclosed in a bag has been widely used. Such pillows can be easily deformed according to the shape of the head, but since they have an indefinite shape, the shape of supporting the head is not constant, and generally the neck tends to sink.

On the other hand, a material, such as urethane foam, which has appropriate elasticity and cushioning properties, but also has shape-retaining properties, is used as a core material, and a cross section is obtained so as to obtain an ideal support form from the human neck to the head. Pillows with a modified shape are also well known. However, despite the fact that there are individual differences in the optimum value for the height of the pillow depending on the physique and shape of the head, it is not possible to change the height with such a pillow, and the height of the pillow does not match. Without it, the core material may have a certain shape-retaining property, which may adversely affect neck fatigue, stiff shoulders, and even the entire body.

Of course, although there is some allowable range due to elastic deformation of the core material, it is not only disadvantageous to prepare products of multiple sizes and shapes for one pillow, but also from among many products. Finding a pillow that fits your body is difficult.

[0005]

[Problems to be solved by the invention]

 In view of the above-mentioned points of the conventional pillow, the present invention makes it easy for the user himself to put the head on the pillow while forming a predetermined cross-sectional shape that fits the body shape from the head to the neck. The purpose was to obtain a pillow that can be adjusted to the proper height.

[0006]

[Means for Solving the Problems]

 A core material having a hollow portion formed over substantially the entire length in the longitudinal direction of the pillow, having appropriate elasticity and cushioning property at least on the upper surface side of the hollow portion, and having a constant shape retention as a whole. And an airtight bag body housed in the cavity, and an air pump connected to the bag body. In the core material, one of the two edge portions of the upper surface along the longitudinal direction of the pillow is higher than the other, and the central portion thereof is substantially equal to or lower in height than the lower edge portion. As a whole, the pillow is reversely inclined in the lateral direction, and the cavity and the bag are arranged along the edge portion on the high side.

[Embodiment of the invention]

 Embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a partially cutaway perspective view showing a pillow 1 according to a typical embodiment of the present invention, and FIG. 2 is a side sectional view showing its usage state. In the figure, a pillow 1 includes a core material 3 having a cavity 2 formed therein, an airtight bag body 4 housed in the cavity 2, an inner bag 5 and an outer bag 6, which cover the core material 3. It mainly comprises an air pump 8 outside the pillow 1 and connected to the bag body 4 via a flexible pipe 7.

The core material 3 is made of a material having appropriate elasticity and cushioning property, for example, an elastic foam such as urethane foam, and an upper surface side member 31, and is relatively hard to the upper surface side member 31. A material, that is, a material having low elasticity and cushioning property, for example, a flat plate-shaped lower surface side member 32 formed of polyethylene foam or the like is integrally joined. In addition to the two-member structure as described above, the core member 3 may have a one-member structure in which the physical properties are different between the upper surface side and the lower surface side, or a combination of three or more members.

In the upper surface side member 31, one of the both end portions 31a and 31b of the upper surface along the longitudinal direction of the pillow 1 has one edge portion 31a on the shoulder side when using the pillow is higher than the other edge portion 31b, The central portions 31c are lower than the lower edge portions 31b, and are generally inclined in the lateral direction of the pillow 1. Then, a large number of protrusions are formed in a uniform distribution on the entire surface of the upper surface side member 31 excluding the joint surface 33 and both side surfaces so that the acupressure effect can be obtained. Further, in the illustrated example, the deodorant sheet 9 is interposed between the upper-side member 31 of the core material 3 and the inner bag 5.

Then, the upper surface side member 31 is cut out in a slightly flat tunnel shape from the joint surface side with the lower surface side member 32 along the entire lengthwise direction of the pillow along the high end side edge portion 31 a, and thus the upper surface side member 31 is cut. The cavity 2 is formed between the side member 31 and the lower surface side member 32.

The air pump 8 connected to the bag body 4 via the flexible pipe 7 can only inhale air by the action of a check valve (not shown) at one end of a hollow container 81 made of a flexible elastic member such as rubber. A flexible air intake port 82 is provided at the other end, and an air supply port 83 is also provided at the other end. The flexible pipe 7 is connected to the air supply port 83, and an exhaust gas is provided at the connection portion. A valve 84 is provided.

When the container 81 is gripped, the air in the container 81 is pressure-fed into the bag body 4 through the air supply port 83 and the flexible pipe 7. When the hand is released, the container 81 elastically recovers and the intake port 82 External air is sucked into the container 81. By repeating this operation, air can be pressed into the bag body 4.

Next, the operation based on the above-described embodiment will be described according to the procedure for adjusting the height of the pillow 1.

First, the exhaust valve 84 of the air pump 8 is loosened, the air in the bag body 4 is once exhausted, and then the exhaust valve 84 is closed. Next, the pillow 1 is placed on the floor surface that is normally used, and the head 11 'is placed so that the edge portion 31a on the high side is on the shoulder side. Then, the bag body 4 is crushed by the weight of the head portion 11 'as shown by 4'in FIG. 2, and the upper surface side member 31 of the core material 3 is elastically deformed by 31' in FIG. In this state, the height of the pillow, in particular, the height of the shoulder side edge portion 31a is insufficient, the head 11 'is slightly tilted forward, and the cervical vertebra 12' is placed in a position to bear the burden.

Therefore, when the air pump 8 is operated with the head resting on the pillow and air is gradually pressed into the bag body 4, the height of the pillow 1 increases in accordance with the air pressure in the bag body 4, If the operation of the air pump 8 is stopped when the proper height for relaxing the whole body is obtained, the pillow 1 is held at that height. Needless to say, the height of the pillow 1 set in this way is the most appropriate height because it is set in the state that the user actually uses it.

Further, in the pillow 1, since the bag body 4 is arranged along the edge portion 31a on the shoulder side, the shoulder 4 is deformed against the deformation amount of the other edge portion 31b of the pillow and the central portion 31c. The amount of deformation of the side edge portion 31a is large, and by deforming the pillow 1 so as to increase the reverse inclination of the pillow 1 as a whole, as the height of the pillow 1 increases, the head 11 conversely tilts forward and the neck The cervical vertebra is always formed on the upper surface of the pillow 1 from the head 11 to the neck like the upper side member 31 shown by the solid line in the figure without sinking the cervical spine and placing a burden on the cervical spine. 12 will be supported so as to form a natural curve.

Since the upper surface side member 31 is made of a relatively flexible material and the lower surface side member 32 is made of a relatively hard material, the deformation of the pillow 1 due to the increase in the air pressure of the bag body 4 is prevented from occurring. In addition to the above-mentioned ideal shape change with reproducibility, which occurs only on the upper surface side, the flat plate-shaped lower surface side member 32 retains its shape, so that the pillow 1 is placed on the floor surface. And stably supported, and the above ideal cross-sectional shape is always obtained.

The pump 8 and the flexible pipe 7 may be removable from the bag body 4. In that case, it is necessary to provide an exhaust valve or a check valve on the side of the bag body 4 at the connecting portion. It

[Effect of the invention]

 As described above, the pillow of the present invention has a hollow portion formed therein over substantially the entire length in the longitudinal direction of the pillow, and has appropriate elasticity and cushioning property at least on the upper surface side of the hollow portion, and as a whole. Since it has a core material having a certain shape-retaining property and an air pump connected to the airtight bag housed in the cavity, the user actually puts his or her head on the pillow. Therefore, the height can be adjusted steplessly by a simple operation of the air pump, and the height can be set to the optimum height for the user regardless of individual differences in physique, head shape and the like. This overcomes the problems of conventional pillows, in that the shape and material are not suitable for the user's own body shape, which adversely affects the human body, and has a shape-retaining core material. This maximizes the advantages of the pillow shape and material, which have an ideal cross-sectional shape, and makes it possible to sleep comfortably.

Further, in the core material, one of both end edge portions of the upper surface along the longitudinal direction of the pillow is higher than the other end portion, and the central portion thereof has substantially the same height as the lower end edge portion, or The height of the pillow is lowered in the lateral direction of the pillow as a whole, and the cavity and the bag are arranged along the edge of the high position side to adjust the height of the pillow. , The cross-sectional shape of the upper surface of the pillow, especially the reverse inclination from the shoulder side to the head side of the human body is maintained or deformed so as to be increased. Therefore, even if the pillow is raised, there is no problem that the head tilts forward and the burden on the cervical spine does not occur, and the natural pillow fits the cervical spine of the human body within the adjustable pillow height. With this, an ideal support form is obtained and a comfortable sleep is possible.
