Description

Memory foam pillow

[0001] The present invention relates to a memory foam pillow, and more particularly, to a memory foam pillow which can maintain a curved line of a cervical vertebrae in a sleeping state to allow a user to take a good night's sleep and to vary the hardness of a pillow, The present invention relates to a memory foam pillow that can take a sleeping state in a comfortable posture by selecting a region (hardness) of a memory foam pillow.

Sleep is the most basic desire for humans and provides time for relaxation, not only supplementing the energy used during the day, but also ensuring that the brain, which is responsible for all biological functions for maintaining life, is in a proper balance.

In recent years, the importance of comfortable sleep has been emphasized and the functional part of the bedding has been emphasized. Especially, in pillow, various forms have been developed for releasing the beneficial substances to the human body or for the neck disk or back pain patient.

The cervical spine (the neck spine) at the top of the person's spine has a natural C-shaped curve in front of it to serve as a buffer to support the weight of the head when it is normally standing. This C curve is maintained at bedtime Failure to take a good sleep or various diseases occur.

On the other hand, the memory foam (Memory Foam) is made of low elasticity polyurethane or latex and is widely applied to bedding such as a pillow because it has a shape that changes smoothly and responds to the body temperature and pressure of the human body, have.

However, since the pillow using the conventional memory foam is generally in a posture in which the cervical vertebra is inclined forward when the person is laid down, the muscles are still in a state of tension so that the fatigue is not easily recovered and the airway narrows, resulting in side effects such as sleep apnea And it is not easy to take a good sleep.

In addition, the height of the pillow supporting the cervical vertebrae at the time of bedtime is important. If the height of the pillow is rather uniform as a whole, the C curve of the cervical vertebra is collapsed to cause shoulder stiffness or dyspnea. It may become unnatural and obstruct blood circulation.

And since existing memory foam pillows have the same hardness in all areas, it is true that they are somewhat inadequate when different hardnesses are needed for each part of human body.

Further, when the use period has elapsed, the pillow formed with low elasticity is deformed, and the head neck or the like can not be properly supported, and the user feels inconvenience.

In addition, the present invention makes it easier and more convenient to manufacture and use the "Memory foam pillow" of the present applicant's registered patent No. 10-2017-119508.

Korean Registered Utility Model No. 20-0365801 Korean Patent No. 10-2017-119508

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems of the prior art, and it is an object of the present invention to provide a cushion device which can keep a curve of a cervical vertebrae (Hardness) of the pillow according to the neck condition of the pillow, so that a comfortable sleeping state can be obtained.

According to an aspect of the present invention, there is provided a memory foam pillow,

Is formed integrally with the second memory foam 300 by varying the hardness of the boundary portion 200. The hardness of the urethane foam is 2 to 15 kgf / 314 cm 2, which can comfortably support the head and neck. A first memory foam (100);

By varying the hardness of the boundary perimeter 200, the first being formed of a memory foam 100 integrally, comfortably the measured value of hardness in the produced polyurethane foam 14-25kg ^f / 314cm ² support the head and neck A second memory foam (300) to allow the user to do;

When the memory foam pillow and the cushion part are closed, the other part is opened. And a cover 700 composed of any one of a button, a zipper and a Velcro tape 730 so as to prevent the pillow and the cushion part from being separated from each other.

At this time, the first memory foam 100 is formed integrally with the second memory foam 300 at a boundary with the boundary 200 as a boundary, and is formed of a urethane foam having a measured hardness value of 2-15 kgf / 314 cm 2 (110) for supporting the head;

And a neck supporting part 130 formed on one side of the head supporting part and extending in a circular shape higher than the height of the head supporting part to support the neck part.

A boundary portion 200 for partitioning the first and second memory foam includes a first through hole 210 for discharging heat and sweat of the head when the head and neck are supported.

And a second through hole (230) provided on both sides of the first through hole to prevent the ears from being pressed when laid sideways.

The second memory foam 300 is formed integrally with the first memory foam 100 at a different hardness from the boundary 200 and has a hardness of 2-15 kgf / (310) for supporting the head;

And a neck supporting part 330 formed on one side of the head supporting part and extending in a circular shape higher than the height of the head supporting part to support the neck part.

The cushion 500 is provided to enclose the memory foam on the outside of the integrated memory foam 100 or 300 to provide a feeling of comfort to the head. The cushion 500 is filled with goose hair, cotton or the like and is fastened to the fixing part 530 A cushion part 510 having any one of a button, a zipper, and a Velcro tape 550;

And a fixing part 530 extending from the cushion part and covering the memory foam, the fixing part 530 being provided with one of a button, a zipper and a Velcro tape 550 to be fastened to the cushion part at one end thereof .

According to the present invention, the memory foam pillow according to the present invention maintains the curvature of the cervical vertebrae (neck bone) intact even when the sleeping surface is maintained, and the pillows are hardened by varying the hardness of the pillow, Hardness) can be selected so that a comfortable sleeping state can be obtained.

By forming a plurality of ventilation lines, air permeability is ensured, so that it is possible to prevent moisture such as heat of the head and sweat from being removed, thereby preventing formation of germs, dust and the like.
