Description

Cervical pillow

The present invention relates to a cervical pillow, and more particularly to a new configuration of a cervical pillow that protects the cervical spine and provides a comfortable and hygienic sleeping environment.

In general, the back of the head is supported by the back of the head. When the back of the head is received, the head is bowed forward, so that the C-shaped cervical vertebra is pressed against the backward flexion. At the same time, A phenomenon of stiffness occurs.

Therefore, even if you take a sleep, your neck becomes stiff rather than refreshing, and if this condition persists, the disease of the neck disk may be triggered.

On the other hand, a cervical pillow is provided for keeping the cervical vertebrae in a correct posture when sleeping. Basically, the cervical pillow has a structure that keeps the head low and supports the neck area.

However, since the conventional cervical vertebrae is configured to support only the cervical vertebrae of the user in a state in which the user is lying straight, it is disadvantageous in that it is inconvenient to use when the user lies sideways while sleeping.

Also, it is often the case that the pillow is often molded into an elastic foam, The pillow is not easy to wash, and even if it is washed, it can not be washed to the inside, so it has a hygiene vulnerability.

Hereinafter, the present invention will be described in more detail with reference to the drawings.

FIG. 1 is a perspective view showing a first embodiment of the present invention, FIGS. 2 to 3 are a side sectional view and a front view, and FIG. 4 is a side view showing a used state. As shown, the present invention comprises the occipital seating groove 110, cervical vertebra 120, back support 130, and left and right head seating 140,150.

The pillow according to the present invention has a slightly elongated shape as a whole, and the occipital seating groove 110 is formed at the center of the pillow. The larynx receiving groove 110 is a portion where the user's larynx is seated in an upright posture, and is recessed in an approximately hemispherical shape.

The cervical vertebra 120 is positioned in front of the occipital groove 110, and the cervical vertebra of the user is supported by the cervical vertebra 120 in a straight posture. The cervical vertebra 120 has an upper surface formed as a curved surface so that a user's cervical spine is comfortably supported. A plurality of magnet pieces 122 are attached to the cervical vertebra 120.

It is known that the magnetic field of the magnet accelerates blood circulation and metabolism, and relieves the pain. The blood circulation is promoted by the magnet piece 122 provided in the cervical vertebra 120 and the pain relieving effect can be obtained.

Preferably, the cervical spine 120 has an insertion groove into which the magnet piece 122 is inserted, and a magnet piece 122 is attached to the insertion groove. If the magnet piece 122 slightly protrudes upward from the cervical spine support 120, the effect of applying the force by the magnet piece 122 can be obtained.

 A back support 130 protruding outward is formed in front of the cervical support 120. The backrest 130 is inserted under the back of the user to support the back of the user. As shown in the drawing, the backrest 130 has a tapered shape protruding outward toward the lower end, thereby supporting a portion connecting the neck and the back of the user comfortably.

On the other hand, left and right head seating portions 140 and 150 are formed on both sides of the occipital seating groove 110 and the cervical vertebra 120. The left and right head seating portions 140 and 150 are formed such that the side surface portion of the user's head is placed on the side of the user in a side lying posture and slightly higher than the cervical support portion 120.

Preferably, the left and right head seating portions 140 and 150 have different heights H1 and H2. Accordingly, the user can conveniently use a portion of the left and right head seating portions 140 and 150 that suits his / her physical condition.

The left and right head seating portions 140 and 150 are formed as curved surfaces. Preferably, the lower ends of the left and right head seating portions 140 and 150 form inward depressed portions 144 and 154, respectively. The front depressions 144, 154 are intended to allow less interference with the shoulders when the user is lying sideways.

When the front end of the left and right head seating portions 140 and 150 is pressed against the shoulder when the user is lying sideways, the height of the left and right head seating portions 140 and 150 may be lowered and the head may not be properly supported. In order to prevent this, in the present invention, the front depressions 144 and 154 are formed below the left and right head seating portions 140 and 150 so that when the user lies sideways, the front ends of the left and right head seating portions 140 and 150 And the user's shoulders are not interfered as much as possible and the head is supported properly.

The left and right head seating portions 140 and 150 are formed with ear prevention grooves 142 and 152 recessed to a predetermined depth so that the user's ears are not pressed by the pillow when the user is lying sideways.

Reference numeral 160 denotes a rear depression that extends laterally from the back of the occipital seating groove 110 and is elongated in the lateral direction of the pillow and is depressed inwards. Since the rear portion of the pillow is a portion having substantially no function, the rear depression 160 is formed in the present invention to reduce the molding material of the pillow, and also to the appearance of the pillow.

On the other hand, the present invention is molded into a polyurethane foam and covered with a separate envelope. Preferably, the pillow according to the present invention comprises 5 to 20 parts by weight of a volcanic rock resin, 35 to 60 parts by weight of methylene diisocyanate, 0.1 to 5.0 parts by weight of a foaming agent and 0.01 to 3.0 parts by weight of a foam stabilizer, based on 100 parts by weight of polypropylene glycol By weight of a urethane composition.

Polypropylene glycol is made by polymerizing ethylene glycol, which is a dihydric alcohol, and has a high foaming tensile strength. Using such polypropylene glycol, a flexible polyurethane foam having good flexibility can be obtained.

Volcanic Ash cancer (火山灰岩) is an amorphous clay mineral produced by the volcanic ejecta of volcanic ash weathering, as an active ingredient, _{SiO 2, Al 2 O 3,} Fe 2 O 3, CaO, MgO, K 2 O, Na 2 O, TiO ₂ . Of these components, TiO ₂ acts as a photocatalyst to remove harmful components by oxidation / reduction, and has an antibacterial function. These volcanic rocks are crushed to a size of 3000 mesh or less.

When the volcanic rock is used in an amount exceeding 20 parts by weight based on 100 parts by weight of the polypropylene glycol, the polyurethane foam foamed to be molded has a very low viscosity, so that the polyurethane foam can not function. If it is used in an amount of less than 5 parts by weight, the effect of the volcanic rock cancer is insignificant.

And methylene diisocyanate is a matrix that reacts with polypropylene glycol to form a polyurethane bond. When the methylene diisocyanate is used in an amount of less than 35 parts by weight based on 100 parts by weight of the polypropylene glycol, the physical properties of the polyurethane foam are weakened. When the methylene diisocyanate is used in an amount exceeding 60 parts by weight, the hardness of the polyurethane foam increases, Which is undesirable.

As the foaming agent, a known foaming agent such as a fluorinated hydrocarbon or water is used. Preferably, water is used as the foaming agent. The foaming agent is used in an amount of 0.1 to 5.0 parts by weight based on 100 parts by weight of the polypropylene glycol.

As the foam stabilizer, silicone foam stabilizer, fluoric foam stabilizer and the like are used, and it is preferable to use silicone foam stabilizer. The foaming agent is used in an amount of 0.01 to 3.0 parts by weight based on 100 parts by weight of the polypropylene glycol.

In addition to the above components, conventional additives such as fillers such as potassium carbonate and barium sulfate, antioxidants, ultraviolet absorbers, plasticizers, and dispersants may be further added to the urethane composition for forming the pillow.

In this embodiment, 20 parts by weight of a volcanic acid fumarate, 40 parts by weight of methylene diisocyanate, 4 parts by weight of water and 0.05 part by weight of SZ-1327 of Doray Dow Corning Co., Ltd. are mixed with 100 parts by weight of polypropylene glycol, A physical property test was performed.

The volcanic rocks used in this embodiment are SiO ₂ 62.0 wt%, Al ₂ O ₃ 16.8 wt%, Fe ₂ O ₃ 4.31 wt%, CaO 1.84 wt%, MgO 0.81 wt%, K ₂ O 1.05 wt%, Na ₂ O 0.79 wt%, TiO ₂ 0.28% by weight.

As can be seen from Table 3, the growth of the fungus strain was observed for 4 weeks. As a result, the growth of the fungus was not confirmed. Thus, it can be seen that the pillow according to the present invention has excellent antifungal properties.

As described above, the pillow according to the present invention has excellent antimicrobial and antifungal properties by containing far-infrared ray which is beneficial to the human body by containing the volcanic rock cancer. Therefore, it is possible to obtain a health promotion effect by the far-infrared ray emitted from the pillow, and even if the pillow is used for a long time, it is sanitary since it is not contaminated by bacteria or fungi.

Hereinafter, other embodiments of the present invention will be described, and the same configurations and effects as those of the above-described embodiments will not be described.

9 and 10 are views showing a second embodiment of the present invention. As shown in the figure, in this embodiment, the auxiliary pad 200 is further provided on the left head seating portion 140 or the right head seating portion 150. The auxiliary pad 200 is formed of the same material as the pillow so as to have a shape corresponding to the upper surface of the left head seating portion 140 or the right head seating portion 150.

The auxiliary pad 200 is for adjusting the height of the left and right head seating portions 140 and 150 according to a user's physical condition. When the height of the left and right head seating portions 140 and 150 does not match the physical condition of the user, the auxiliary pad 200 is put on the left head seating portion 140 or the right head seating portion 150 and used.

Preferably, a fixing protrusion 201 having a shape corresponding to the earmold prevention grooves 142 and 152 is protruded from the bottom surface of the auxiliary pad 200. Therefore, when the auxiliary pad 200 is placed on the left head seating portion 140 or the right head seating portion 150, the fixing protrusions 201 are inserted into the ear prevention grooves 142 and 152, Flow is prevented.

Since the auxiliary pad 200 is prevented from flowing as described above, even if the user moves, the auxiliary pad 200 flows and the state of being placed on the right head seating portions 140 and 150 is not disturbed.
