Description

Pillow with multi-layered structure

The present invention relates to a pillow.

In general, various pillows have been proposed as articles suitable for a person to sleep.

When using a pillow such as a needle or a stone pillow, the height of the cervical spine can be kept constant, but the muscles and skeletons of the head, cervical spine, or dorsal part may become excessive, and blood circulation It's susceptible to damage and can cause muscle or nerve damage. Therefore, the height of the pillow is too low or has a rigid hardness to the pillow not only to maintain the normal curvature of the user's cervical spine, but also prevents a good night's sleep by disturbing the circulation of the brain.

On the other hand, people with bowed heads, such as using a computer, who work with their heads bent and their dorsal ridges in front of them, who have the so-called Turtle Neck Syndrome, prefer high pillows. The flow of blood can be disturbed, and the C-shaped curve of the cervical spine can be reversed.

Or, if you use a pillow filled with feathers or cotton, you may feel comfortable but are too soft to bury your head and neck and keep the curve of your cervical spine. To compensate for this, the pillow is made high and wide, but in this case, the center of the pillow is out of the center of gravity of the head and the pillow tends to escape from the head, resulting in abnormal curvature of the cervical spine.

Latex and memory foam pillows have recently become popular. Latex or memory foam pillows have the advantage of excellent shock absorbing ability and unlike the pillows described above, their contents do not lean to one side and are well restored after use. However, it is difficult to maintain the structure of the normal cervical spine during sleep due to the large compression rate, so that discomfort is not solved.

In addition, a pillow for posture correction is also commercially available, but was designed to maintain the normal curvature of the neck, but there is a limit in matching the overall shape of the head or the back of the neck of the person, and the situation is unsatisfactory in wearing comfort.

On the other hand, for example, Japanese Patent Laid-Open Publication No. 2005-110702 (name of the pillow "a method of manufacturing the pillow") has a hardness of the low repulsion core layer using a polyurethane foam and the core layer. A pillow in which a low surface layer is integrated and its manufacturing method are disclosed (patent document 1).

In addition, US Patent No. 5,689,844 (named "Pillow") discloses a multilayer pillow that constitutes an inner layer, an intermediate layer, and a surface layer and forms a plurality of air gaps between the layers (Patent Document 2).

In addition, PCT International Publication No. WO 92/03957 (named "Articles of Bedding and the Like") has a non-rigid core, which forms a core, an air impermeable intermediate layer, and a surface layer between them. Pillows for limiting a plurality of air flow is disclosed (Patent Document 3).

In addition, U.S. Patent No. 4,799,275 (named "Shock Absorbing Pillow") has an impact comprising an elastically deformable core, an impermeable membrane surrounding the core, a means for controlling the flow of air through the membrane, and a cushion agent composed of a fibrous layer. An absorption pillow is disclosed (patent document 4).

The pillows proposed in Patent Literatures 1-4 have a multi-structure that forms a proper height when lying down, and in the case of bedtime, the body is comfortably maintained by cushioning during impact to minimize the burden on the head and cervical spine, including the brain. Or doing it comfortably.

However, these patent documents 1-4 are all discontinuously arranged in a structure having a significantly different strength for each layer of the cushioning material has a disadvantage that can not maintain the cushion when using the continuous pillow does not give the convenience, comfort or posture correction effect of the body. . In other words, if the user uses the pillow for a long time, if any one of the inner layer, middle layer, and surface layer loses a large feeling of cushioning, it is insufficient to maintain the normal curvature of the cervical spine by supporting the neck of the pillow user. There is a limit that can not maintain the comfort of the bed because the entire spine, including the do not fit on the line of the same height.

Therefore, in order for the pillow to be used more appropriately with ideal conditions, it is possible to maintain a constant height or strength of the pillow according to the shape of the head or cervical spine of the user, and to have moderate hardness so that muscles or blood vessels cannot be compressed, and also comfort Should be able to give. As a result, the pillows described in Patent Documents 1 to 4, and the neck, or latex or memory foam pillows have limitations in having suitable conditions for the pillows. Therefore, a pillow is required to maintain a constant height or strength of the pillow and to obtain a comfortable fit. Will be done.

The hollow portion 25 may have a cross section of a trapezoidal shape.

The outer layer 24 has an opening 202 for reducing stress caused by the user when the user cuts the pillow.

In addition, the pillow 10 has a size such that the length of the core 20, the middle layer 22, and the outer layer 24 can support the head and cervical spine portions at a uniform pressure. As the height of the pillow 10, the first support 30a is preferably approximately twice as large as the second support 30b. However, the length and height of the pillow 10 is not limited to the size described above, those skilled in the art can easily understand that can be carried out by varying the length and height.

In addition, the pillow 10 in the material, the core 20 may be selected from urethane, silicone, wood, etc. to have a hardness similar to the arm bones of the human body. The intermediate layer 22 may be selected from high elastic polyurethane foam, silicone foam, and the like. The outer layer 24 may be made of low elastic polyurethane foam or latex foam to maintain a soft fit while minimizing pressure on the head and cervical spine.

In addition, the pillow 10 has a strength and elasticity that is weaker than that of the core 20, but stronger than that of the outer layer 22.

Now, a core 20, an intermediate layer 22 and an outer layer 24 constituting a pillow having multiple structures according to another embodiment of the present invention will be described.

FIG. 10 is a cross-sectional view of the pillow having the multiple structure of FIG. 9. Referring to FIG. 10, a predetermined hollow portion 25 is formed between the core 20, the intermediate layer 22, and the outer layer 24. .

The core 20 has a hardness enough to maintain the structure of the cervical spine from the head to the thoracic vertebrae against the pressure of the human body after lying down. On the other hand, the artificial bone can be replaced with other components. For example, the core 20 may be replaced with a material selected from urethane, silicone, wood, etc. to have bone-like properties. The core 20 is positioned to be substantially coincident with the center of the cervical spine portion of the head and cervical spine to maintain the structure of the entire pillow 10. The cervical spine structure also maintains the normal posture of the cervical spine and serves to correct the crooked cervical spine.

The intermediate layer 22 is a portion supporting the cervical spine, and has an intermediate hardness and elasticity between the outer layer 24 and the core 20.

Hollow portion 25 is an empty space formed inside the outer layer 24, the shape is determined according to the shape of the outer boundary 22b of the intermediate layer 22 and the neighboring inclined portion 22c, The air in the interior of the hollow part 25 is mainly vented through the outer layer 24.

The intermediate layer 22 may be made of a material having elasticity selected from high elastic polyurethane foam, silicone foam, and the like. According to the intermediate layer 22, when the intermediate layer 22 is pressured due to the weight of the cervical vertebrae to form a structure that can easily disperse the pressure into a plurality of grooves 222, and the elastic material This allows the head to provide elasticity to the cervical spine while maintaining the overall shape of the cervical spine.

14 is a cross-sectional view of a pillow having multiple structures according to another embodiment of the present invention. Referring to FIG. 14, the configuration of the intermediate layer 22 and the outer layer 24 of the pillow 10 is substantially the same as illustrated in FIG. 9, and there is a structural difference in which the core may be omitted.

According to another embodiment of the present invention, a pillow having a multiple structure is similar to the pillow illustrated in FIG. 9. The outer layer 24 may include a first support part 30a and an upper support part 30a on the upper side of the core 20. It has the 2nd support part 30b extended in 30a, and the said 1st support part 30a and the 2nd support part 30b are comprised in a different shape. In addition, the outer layer 24 has a basic shape having at least one opening 302 along the longitudinal direction of the outer layer 24, the first support portion 30a is a circular shape approximately coinciding with the bending of the cervical spine, The second support part 30b has a shape that substantially corresponds to the curvature of the head to support the entire weight according to the height of the cervical spine and the head while distributing pressure to provide comfort.

The outer layer 24 also uses low elastic polyurethane foam, latex foam to maintain a soft fit, similar to the pillow illustrated in FIG.

15 (a) and 15 (b) are diagrams showing still another embodiment of the present invention of the pressure generated around the pillow of FIG. 9, wherein the pillow 10 is placed before and after the head of the person is placed on the pillow 10; 10) shows an example of pressure generated in the vicinity.

15 (a) and 15 (b) show the neck of the neck when the head is directly lying down during sleep as in the state of use after the person shown in Fig. 15 (b) is laid down in the initial state shown in Fig. 15 (a). If the pillow 10 supports the section d from the starting point A to the apex B of the head, the pillow 10 may support the normal curvature of the cervical spine. The intermediate layer 22 is located in the outer layer 24 and the intermediate layer 22 is not directly supported near the apex B to maintain the normal curvature of the cervical spine due to the bias of the center of gravity of the pillow. Therefore, when the user cuts the pillow, the center of gravity supported by the pillow is moved toward the cervical spine of the user, thereby bringing the effect of posture correction.

As shown in (a) of FIG. 15, the center of gravity of the pillow 10 is not biased in the state before the head of the person is positioned. Therefore, uniform pressure is received from the center of the pillow 10. However, after the head is positioned as shown in (b) of FIG. 15, it is shown that the pressure around the pillow 10 is uniformly received throughout the entire region without any phenomenon of pressure on either side.

FIG. 16 is a state diagram of use of the intermediate layer 22 of the pillow shown in FIG. 9 or FIG. 15.

According to the structure of the intermediate layer 22 shown in FIGS. 16A and 16B, at least one groove 222 is formed in the intermediate layer 22 as well as the hollow portion 25 formed inside the outer layer 24. It is configured to form.

Since the pressure of the cervical spine is dispersed in the hollow portion 25 and the groove 222 of the intermediate layer 22 when the pillow is worn, the stress f of the intermediate layer 22 is uniformly transmitted between the center and the periphery thereof. Therefore, the uniformity of the pressure applied to the predetermined hollow portion 25 and the groove 222 of the intermediate layer 22 can be ensured excellently.

Therefore, the pillow having a multiple structure of the present invention, the core corresponding to the bones of the human body to maintain the overall structure of the pillow and to maintain the normal spine posture during sleep, having the elasticity corresponding to the muscles of the human body The intermediate layer is included, so you can feel elasticity and comfort, and you can not only get a soft feeling due to the soft outer layer corresponding to the soft tissues and skin of the human body, but also include different sections of different heights of each layer. Select and use the best part of your pillow.
