DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a pillow.

[0002]

2. Description of the Related Art Generally, it is considered that the overall bedding has a great effect on obtaining a comfortable sleep, and the current situation is that development is being conducted mainly on the weight of a futon and a cotton material. . However, it is also true that the sleeping state is greatly affected by the pillow so that it is said that you can not sleep if the pillow is changed, and since ancient times, the filling amount of red beans and buckwheat that are the contents of the pillow must be changed It was pointed out that the hardness and height of the pillow were adjusted depending on the pillow, but the height and shape of the pillow changed each time the pillow was used, so that the optimal pillow condition could not be clearly determined individually.

In view of the above, pillows for obtaining a comfortable sleep have been conventionally proposed. Among the methods for manufacturing the pillow, there is a technique disclosed in Japanese Patent Application Laid-Open No. 61-253015. This technology uses a pillow user's head or head and neck or head and neck and shoulder and mouth before measuring and examining the head or head and neck or head and neck of the pillow user. A pillow manufactured by a suitable shape, height and size or hardness or a pillow-forming material for a part and a shoulder part, which aims to provide a pillow that is suitable for each body. Met.

[0004] Conventional pillows having a characteristic structure include:
There is a technique disclosed in Japanese Patent Application Laid-Open No. 3-15417. This technology uses a material having a good shape-retaining property to form a pillow core body having a recessed region where the head comes into contact with the pillow bag so that the top surface of the pillow bag is horizontal when the pillow core body is not used A pillow, wherein the head is suspended by a pillow bag without touching the bottom surface of the recess when the head is put on the pillow. Since the head is hung on a hammock, the weight of the head is not remarkably concentrated on one place.

[0005]

However, in the former of the above-mentioned techniques, it is proposed that the pillow be formed in a shape that fits the head, neck, etc.
The specific shape and the material for maintaining the shape are not shown, and the preferred shape and material are not specific, and it is difficult to produce a suitable pillow by the above production method. Was something. Moreover, even if it is configured to fit the head or neck, it is uncomfortable if the head and neck have no freedom at all, and at best the contacting part of the head should be flat or concave, The abutting part of the part must be raised, and the measurement results of the head and neck cannot be fully utilized.

In the latter case, the head is suspended while the upper surface of the pillow bag hangs down from the hollow recess, so that the entire weight of the head is supported by the pillow bag and the durability is maintained. There was a problem with sex. In addition, in order to hang it like a hammock, it is necessary to have flexibility like a net material, and it is not easy to provide flexibility like a net material while forming a pillow bag.

As described above, in the prior art, it has been pursued how to reduce the burden by dispersing the weight of the head and neck, but all are ideal but realistic. It was not something. That is, mass production is very difficult, or the cost is high due to the complicated structure. An object of the present invention is to provide a pillow that allows a comfortable sleep and enables mass production in view of the above points.

SUMMARY OF THE INVENTION The present invention relates to a pillow having a rear cervical support made of a relatively hard material at a position for supporting the rear cervix during use. The pillow is characterized in that the pillow is characterized by being constituted by a substantially spherical spherical portion disposed opposite to both sides and a constricted portion provided relatively low in the middle of the opposed spherical surfaces. I do.

Further, the present invention provides a pillow having a concave head contact portion in the center, and the periphery of the head contact portion being formed in a convex shape. A rear neck support portion made of a hard material is provided, and the rear neck support portion is formed into a protruding curved surface, and two spherical surfaces arranged so that the protruding sides face each other. A pillow is also characterized in that the pillow is constituted by a portion and a constricted portion provided relatively low in the middle between the opposed spherical surfaces.

[0010] It is preferable that the rear neck support is a rear neck support configured such that the height of the constricted portion is higher than the head contact portion and lower than the convex shape. Further, it is preferable that the rear neck support is disposed on a relatively soft material, and the rear neck support is integrally formed of hard urethane foam, and the other members are made of soft urethane. It is preferably formed by a foam.

[0011]

Embodiments of the present invention will be described below with reference to the drawings. In the first embodiment, as shown in FIG. 1, a part of a pillow 10 having a flat head contact portion 11 which is raised so as to be able to support just a rear neck is provided at a part of the pillow 10. The rear neck support portion 13 is provided. The head contact portion 11 and the raised portion 12 that constitute the majority of the pillow 10 are formed of soft urethane foam, and are adjusted to the same hardness as a normal pillow. On the other hand, the back neck support portion 13 is formed by molding a hard urethane foam, and is configured to be considerably harder than the surrounding head contact portion 11 and the like.

Here, the structure of the rear neck support portion 13 will be described in detail. The rear neck support portion 13 is provided with spherical portions 14 and 15 protruding on both sides facing each other.
Reference numerals 4 and 15 are both formed so as to include similar substantially spherical projecting curved surfaces, and are arranged such that the projecting sides face each other. A constricted portion 16 which is lower than the spherical portions 14 and 15 is provided between the spherical portions 14 and 15 and is formed integrally with the spherical portions 14 and 15. The constricted portion 16 is adjusted to be slightly higher than the head contact portion 11, has a predetermined length as shown in FIG. 2A, and has a predetermined length as shown in FIG. b) As shown in FIG.
15 is narrower than the head, and the head is
When placed on the neck, the constricted portion 16 is configured to be linearly supported just across the rear neck. Further, since the constricted portion 16 is adjusted to be slightly longer than the thickness of the neck of a general adult, the spherical portions 14 and 15 on both sides in the state where the rear neck is in contact with the constricted portion 16, There may be a gap between the neck and the neck. That is, the spherical portions 14 and 15 on both sides are located near the chin, so that the head has some play, but cannot be largely turned sideways. Therefore, since the head does not turn sideways, it is possible to prevent an unnatural posture during sleep, and obtain an effect of reducing the occurrence of snoring by keeping the throat and the like normal. In addition, a part of the weight of the head is supported by the back neck, and the constricted portion 16 also has a massage action on the back neck. Further, if the constricted portion 16 is made to abut below the rear neck (FIG. 2 (b), the middle head is moved to the left), the shoulder opening just makes contact with the spherical portions 14 and 15 on both sides. By maintaining this state for a while, it is possible to relieve stiff shoulders, and it is possible to sleep in this state.

Next, a second embodiment will be described.
In the present embodiment, as shown in FIG. 3, the pillow 20 is not provided with the flat head contact portion 11 in the first embodiment, and instead has a raised convex portion 21 at one end. It is provided throughout. Further, the other convex portion 22 is provided with a rear neck support portion 23 similar to that of the first embodiment, and when the rear neck portion is brought into contact with the rear neck support portion 23, the above-mentioned second neck portion is provided. It can be used as one embodiment, and can be used like a normal pillow by bringing the rear neck portion into contact with the convex portion 21. Therefore, this convex portion 21 and the other convex portion 2
2 is low, and a concave portion 27 is formed. As shown in FIG. 4, the concave portion 27 can stabilize the state in which the head abuts in the same manner regardless of whether the rear neck support portion 23 is used or when it is used as a normal pillow. It can be done.

It is needless to say that various embodiments can be adopted without departing from the spirit of the present invention. For example, in each of the above embodiments, only the basic structure has been described.
Or a surface layer provided with a large number of protrusions on the surface of the convex portion 21 and the concave upper portion 27. In this case, the hardness of the entire pillow is adjusted by molding with a semi-rigid urethane foam. Can be. In addition, as a matter of course, the pillows 10 and 20 of the above embodiment are used by being put in a pillow cover.

[0015]

As described above, the present invention relates to a pillow having a rear neck support portion made of a relatively hard material at a position for supporting the rear neck portion during use. The pillow is characterized in that the pillow is constituted by a substantially spherical spherical portion arranged on both sides facing each other and a constricted portion provided relatively low in the middle of the opposed spherical surfaces. Therefore, at the time of use, the back neck is supported by the back neck support portion, so that the weight of the entire head can be distributed to the back of the head and the back neck, and the weight acting on the back neck can be reduced by the back neck. It will be massaged at the part support. Further, when the rear neck is supported by the rear neck support, the rear neck is brought into contact with the neck of the rear neck support, so that the spherical portions provided on both sides of the neck are opposed to each other. Since it is located near the chin and the head is prevented from remarkably tilting, a comfortable sleeping state can be maintained without sleeping in an unreasonable posture. Further, when the constricted portion is brought into contact with the vicinity of the shoulder opening, a part of the surface of the spherical portion on both sides comes into contact with the shoulder, so that it can be used for massaging the shoulder.

Further, the present invention relates to a pillow having a concave head contact portion at the center and a periphery of the head contact portion being formed in a convex shape, wherein a relatively small part of the convex shape is used. A rear neck support portion made of a hard material is provided, and the rear neck support portion is formed into a protruding curved surface, and two spherical surfaces arranged so that the protruding sides face each other. And a pillow characterized by being constituted by a constricted portion provided relatively low in the middle of the opposed spherical surfaces, so that the rear neck is supported by the rear neck support. In the state of being supported, the head can contact the concave head contact portion, so that the entire head is stabilized, and the rear neck portion has a convex shape at the portion where the rear neck support portion is not provided. In this state, the head comes into contact with the concave head contact part, Use of Te in which it becomes possible.

[0017] If the rear neck support portion is configured so that the height of the constricted portion is higher than the head contact portion and lower than the convex shape, the rear neck support portion can be compared with the one used. While the height of the constricted portion made of a hard material hardly changes, the head abutment portion sinks slightly, so that the back neck is slightly higher than the back of the head, so that it is possible to sleep in a suitable posture. Further, since the rear neck support portion is disposed on a relatively soft material, when the rear neck portion is supported by the neck support portion, the hardness can be relaxed and comfortable. A feeling of use can be obtained. And while the said back neck support part is integrally molded by rigid urethane foam,
Since the other members are formed of soft urethane foam, they can be mass-produced by molding, and a stable quality pillow can be obtained.
