Description

Functional pillow {Functional pillow}

The present invention relates to a pillow that hangs on the head when lying down for sleep or rest.

In general, humans sleep for about one-third of their lifespan, allowing physiological activities to ease one's fatigue and accumulate energy for the next day's activities.

To do this, it is necessary to secure enough sleep time, but it is very important to have a good night's sleep. Studies have shown that pillows play a very important role in helping you get a good night's sleep.

Pillows commonly used in homes are generally filled with a pillow-like cushioning material in a woven pillow cover and covered with a pillow cover on the outside, with the back of the head supported by the cushioning material. Allow them to sleep and relax.

On the other hand, the cervical spine of the neck effectively supports the weight of the head, and forms a C-shaped curve to relieve and distribute the impact force when walking or running. However, when the pillow of the above-described structure is used, the cervical spine cannot properly support the cervical spine during sleep, and thus, the cervical spine is not maintained in a C-curve but is bent in reverse to be straightened to cause a neck disc, a waist disc, or a stiff shoulder. This can be In addition, the nerves and blood vessels passing through the cervical spine are under pressure so that metabolism is not smoothly performed, so that a good night's sleep is not possible. In order to solve this problem, pillows of various structures have been proposed.

1 to 6, the functional pillow 100 according to an embodiment of the present invention includes a pillow body 110, a pair of pillow support 120, and a pillow cover 130.

Pillow body 110 is made of a memory foam. Memory Foam is a material developed by NASA to mitigate the impact of astronauts on spacecraft launches. Since the memory foam has a restoring force to gradually return to its original shape when pressed, the pillow body 110 may appropriately distribute the pressure of pressing the head and the cervical spine by the restoring force of the memory foam as a whole. Pillow body 110 is made of a high-density memory foam made of polyol can provide excellent restoring force and pressure dispersion effect.

The pillow body 110 has a cervical spine support 111 and a head support 112 for supporting the cervical spine and the head of the user on the basis of the user lying down. The pillow body 110 may have a flat bottom surface.

The cervical spine support 111 maintains the cervical spine in a C-shaped curve during sleep so that a good night's sleep can be taken. An average adult male and female cervical spine has a straight length of 107.5mm and an angle of 20 °. The cervical spine support 111 may be formed in a shape and size capable of maintaining an average adult male and female cervical spine in the form of a C-shaped curve.

The cervical spine support 111 may extend convexly curved along the longitudinal direction of the pillow body 110 from the edge of the pillow body 110 adjacent to the neck. The longitudinal direction of the pillow body 110 is a direction connecting the user's head and neck. Cervical support portion 111 may be formed to have a predetermined cross-sectional area in the left and right directions.

The head support part 112 is a concave support part 112a extending in a concave curved shape along the longitudinal direction of the pillow body 110 from the cervical spine support part 111, and the length of the pillow body 110 from the concave support part 112a. It may include a convex support (112b) extending in a convex curved shape along the direction. In addition, the extended edge of the convex support 112b is connected to the edge of the pillow body 110 adjacent to the head. The convex support 112b may protrude to a lower height than the cervical spine support 111 based on the lower surface of the pillow body 110.

Head support 112 may be formed to have a predetermined cross-sectional area in the left and right directions. The left and right widths of the head support part 112 may be set to be equal to the left and right widths of the cervical spine support part 111. The head support 112 may be set in a shape and size reflecting the head and shoulder lengths of the average adult man and woman.

The pillow body 110 may provide comfortable breathability through fine air cells generated when the memory foam is processed by three-dimensionally cutting the memory foam to have the aforementioned shape. Therefore, the user may feel comfortable when sleeping.

The pair of pillow supporters 120 are disposed at the left and right edges of the pillow body 110 at intervals from one another. Pillow support 120 forms a space (S) on the lower side of the pillow body 110 while being spaced apart from each other. Therefore, the pillow body 110 may be settled through the lower space (S) while being deformed by the pressure of the head and cervical spine. The left edge of the left pillow support 120 is disposed to match or adjacent to the left edge of the pillow body 110, the right edge of the right pillow support 120 is arranged to match or adjacent to the right edge of the pillow body 110 Can be.

As illustrated in FIG. 6, the pillow rests 120 may be formed to have a predetermined distance d from each other. The pillow rests 120 may have a predetermined width d between each of the left and right widths thereof.

Left and right width w of each pillow support 120 may be set to a value within the range of 80 ~ 100mm. Thickness t1 of each pillow support 120 may be set to a value within the range of 12 ~ 30mm. The length of each pillow support 120 may be set equal to the length of the pillow body (110). The operation of the pillow support 120 will be described later.

Pillow support 120 is connected by the support connecting portion 121 at each upper side. The base connection portion 121 may have an upper surface area equal to the lower surface area of the pillow body 110. When the upper surface of the pillow support 120 is covered by the cushion seat 140, the support connecting portion 121 has an extended upper area to support both edges of the cushion seat 140 exposed from the pillow body 110 Can have

The base connection portion 121 may have a predetermined thickness. For example, the thickness t2 of the base connecting portion 121 may be set to 5 mm. The pillow bases 120 may be connected to the left and right edges of the bottom surface of the base connecting portion 121. Here, the pillow base 120 may be formed to be integrated with the base connection portion 121 of the same material. Although not shown, the support connecting portion 121 may be formed in a concave rounded shape of the inner boundary portion connected to the pillow support 120 may increase durability.

Support connection portion 121 is disposed on the lower surface of the pillow body 110 in a state capable of being separated from the pillow body (110). That is, the support connecting portion 121 is simply placed in contact with the surface without being bonded to the lower surface of the pillow body 110. Therefore, the pillow base 120 may be put together or taken out in the pillow cover 130 as needed in a state connected to the base connection portion 121.

Pillow support 120 and the support connection portion 121 may be made of a memory foam material in the same manner as the pillow body (110). Pillow support 120 and the support connection portion 121 may be covered by the support cover 122. The base cover 122 surrounds the pillow bases 120 and the base connecting portion 121 to prevent discoloration of the pillow bases 120 and the base connecting portion 121. The base cover 122 may be made of various fiber materials.

Although not shown, the support cover 122 may be provided with a zipper so that the pillow support 120 and the support connection portion 121 can be easily covered or peeled off. The base cover 122 may be sewn in a state in which the pillow bases 120 and the base connecting portion 121 are wrapped.

The pillow cover 130 accommodates the pillow body 110, the pillow support 120 and the support connecting portion 121 while maintaining the respective positions of the pillow support 120 relative to the pillow body 110. The pillow cover 130 is a pillow body by tightly wrapping the pillow body 110 and the pillow support 120 and the support connecting portion 121 in a state in which the support connecting portion 121 is in close contact with the lower surface of the pillow body 110, Each position of the pillow rests 120 relative to 110 may be maintained.

Although not shown, the pillow cover 130 may be provided with a zipper so that the pillow body 110 and the pillow support 120 and the support connection portion 121 can be easily covered or peeled off.

The pillow cover 130 may include an inner cover 131 and an outer cover 132. The inner cover 131 may be made of a fabric having waterproofness and breathability, such as an aqua fabric, to cover the pillow body 110, the pillow bases 120, and the base connection unit 130. Therefore, the inner cover 131 prevents sweat and body fluids from directly contacting the pillow body 110, which may occur during sleep, and provides comfort by allowing air to pass through. When the upper surface of the pillow body 110 is covered by the cushion sheet 140, the inner cover 131 may cover the cushion sheet 140 to prevent sweat and body fluids directly contact the pillow body (110).

The outer cover 132 may be formed such that the left and right side surfaces cover the left and right side surfaces of the inner cover 131 with mesh fabric in order to maximize breathability. In addition, the outer cover 132 may be formed to cover portions other than the left and right sides of the inner cover 131 with a fabric that may give a warmth, for example, a velour fabric.

The functional pillow 100 may further include a cushion sheet 140 covering the upper surface of the pillow body 110. The cushion sheet 140 may have a constant outer thickness. The cushion seat 140 may be formed in the same shape as the top surface of the pillow body 110. The cushion seat 140 may be disposed on an upper surface of the pillow body 110 in a state in which the cushion sheet 140 may be detached from the pillow body 110. That is, the cushion seat 140 may be simply placed in contact with the surface of the pillow body 110 without being bonded to the top surface of the pillow body 110. The cushion sheet 140 may be accommodated in the pillow cover 130 while being in close contact with the upper surface of the pillow body 110.

For example, as illustrated in FIGS. 7 and 8, the cushion sheet 140 may include a lower sheet portion 141 and an upper sheet portion 142. The lower sheet part 141 has first through holes 141a which are vertically penetrated. The first through holes 141a each have a regular hexagonal cross section. The first through holes 141a are spaced apart from each other at regular intervals by the first partition 141b and arranged in the horizontal and vertical directions.

The upper sheet portion 142 is formed above the lower sheet portion 141. The upper sheet portion 142 may be integrally bonded to the lower sheet portion 141. The upper sheet portion 142 has second through holes 142a which are vertically penetrated. The second through holes 142a have a regular hexagonal cross section larger than the first through holes 141a. The second through holes 142a are spaced apart from each other at regular intervals by the second partition 142b having a left and right thickness that is thinner than the left and right thicknesses of the first partition 141b, and are arranged in the horizontal and vertical directions.

The centers of the first through holes 141a and the first partitions 141b are formed to coincide with the centers of the second through holes 142a and the second partitions 142b. Therefore, the cushion seat 140 takes a double honeycomb structure by the first and second through holes 141a and 142a, but the thickness of the first and second partitions 141b and 142b is different. Due to the stepped formation.

Reinforcing ribs 143 may be formed in the first and second through holes 141a and 142a. The reinforcing rib 143 may have a structure in which three straight rib portions are connected to each other at the center thereof. Six ends of the reinforcing rib 143 may be connected to six surfaces at the boundary of the first and second partitions 141b and 142b. Therefore, the reinforcing rib 143 may support the first partition 141b and the second partition 142b in the horizontal direction to increase durability of the cushion sheet 140.

The composition used in the manufacture of the cushion sheet 140 may include a mixture of a polystyrene-based polymer and a copolymer of polypropylene and an oil. Polystyrene-based polymers have a triblock structure. The polystyrene-based polymer may be styrene- (ethylene / buthylene) -styrene block copolymer (SEBS) or polystyrene-block-poly (ethylene-ethylene / propylene) -block polystyrene (SEEEPS). Therefore, the copolymer copolymerized with the polystyrene-based polymer and polypropylene may be PP-SEBS.

The mixture may include 30 to 40% by weight of the copolymer copolymerized with the polystyrene-based polymer and polypropylene and 60 to 70% by weight of the oil. Here, when the oil content is less than 60% by weight, the hardness (Shore A) is increased, so that the effect of suppression dispersion is reduced and the shrinkage rate is very large, so that ejecting during injection is very difficult, and when it exceeds 70% by weight, the oil and copolymer Injection is not possible because it is not easy to mix, and even if it is injection, it is preferable to set the oil content in the above range because oil blooming occurs during use.

The composition may comprise 5 to 8 parts by weight of an additive based on 100 parts by weight of the mixture of the copolymer and the oil. In this case, when the content of the additive is used less than 5 weight, the oil and the copolymer may not be mixed, and thus the physical properties may be lowered. When the content of the additive is more than 8 weight, it is preferable to add the additive in the above content range because the hardness increases. The additive is to remove oil blooming and to improve heat resistance of the gel cushion, and dry silica or wet silica may be used. Fumed Silica may be used as the dry silica.

The composition may further comprise a heat stabilizer as necessary to prevent deterioration by heating during molding. Here, the composition may include 0.3 to 0.7 parts by weight of the heat stabilizer relative to 100 parts by weight of the mixture consisting of a copolymer and an oil.

The heat stabilizer consists of organic phosphites such as triphenyl phosphite, tris- (2,6-dimethylphenyl) phosphite, tris- (mixture of mono- and di-nonylphenyl) phosphites, or dimethylbenzene phosphonate It may consist of phosphonates such as, or of phosphates such as trimethyl phosphate, or a combination thereof.

The composition may include aromatherapy and antibacterial function to the cushion sheet 140, including 0.5 to 5.0 parts by weight of fragrance oil and 0.05 to 10.0 parts by weight of antimicrobial agent, relative to 100 parts by weight of the mixture consisting of a copolymer and an oil.

When the content of the fragrance oil is less than 0.5 parts by weight, it is difficult to obtain the aromatherapy effect, and when it exceeds 5.0 parts by weight, the physical properties of the composition may be lowered. The fragrance oil may be extracted from at least one selected from the group consisting of lavender, grapefruit, eucalyptus, rosemary, peppermint and ylang-ylang.

If the content of the antimicrobial agent is less than 0.05 parts by weight, the antimicrobial activity value is less than 2, it is difficult to exert an antimicrobial effect, and when it exceeds 10.0 parts by weight, bubbles are generated in the manufacturing process of the cushion sheet 140, property deterioration, unmolding or weighing A trouble such as impossibility may occur. The antimicrobial agent may be an organic or inorganic antimicrobial agent. The organic antimicrobial agent may be zinc bis (2-pyridinethiol-1-oxide).

Thus, the cushion seat 140 is made of the above-described structure and material, compared to the general sheet made of a flat structure and a urethane material, the maximum body pressure and temperature and humidity change rate is low, and the elevation delay time is shortened. .

That is, the cushion seat 140 has a relatively thick first barrier rib 141b of the lower seat part 141 which contacts the pillow body 110, and thus, the deformation of the cushion seat 140 may be minimized and supported stably. The second partition wall 142b of the top sheet portion 142 may be configured relatively thin to provide comfort.

Accordingly, the cushion sheet 140 may optimally distribute the pressure applied to the scalp during sleep so as not to press the skin and the microvascular vessel at a low critical pressure, thereby providing optimum comfort. In addition, the cushion seat 140 can effectively provide moisture and sweat through the air pumping effect and excellent breathability of the double honeycomb structure of the heat and sweat of the head during sleep can provide comfort.

An operation example of the functional pillow 100 having the above-described configuration will be described below with reference to FIGS. 9 and 10.

As shown in FIG. 9, when the user lays down in a standing position and crushes the head on the central upper surface of the functional pillow 100, the cushion seat 140 and the pillow body 110 are connected to the cervical spine support 111 and the head support 112. By being deformed while supporting the cervical vertebra and head of the user's neck by sinking through the space (S) between the pillow support 120 is maintained at a suitable height.

At this time, the cushion seat 140 and the pillow body 110 is settled through the space (S) between the pillow support 120, while dispersing the pressure applied by the head and neck and at the same time the left and right parts of the head And will wrap around the neck. Therefore, the user can increase the degree of feeling warmer than when the pillow body 110 is made of a flat bottom structure without the pillow support 120 on the lower side.

As shown in Figure 10, the user is lying on the side to position the head and neck to correspond to either pillow support 120, the cushion seat 140 and the pillow body 110 together with the pillow support 120 When supported, it can be held at a height suitable for sleeping in a side lying position. Therefore, the user can be prevented from stiff neck by maintaining the correct posture during sleep.

As the thickness of the pillow support 120 decreases, the warmth felt by the user decreases, and as the thickness of the pillow support 120 becomes thicker, the left and right portions of the cushion seat and the pillow body 110 wrap around the head and neck. It may grow uncomfortable. Therefore, the thickness of the pillow support 120 may be set to a value within the range of 12 ~ 30mm.

As the left and right width of the pillow support 120 becomes narrower, the area supporting the head and neck becomes smaller in the posture of the user lying sideways, so that it is difficult to maintain the height suitable for sleeping, and the wider the left and right width of the pillow support 120 becomes the cushion The left and right portions of the seat 140 and the pillow body 110 wrap around the head and the neck so that the warmth can be reduced. Therefore, the left and right width of the pillow support 120 may be set to a value within the range of 80 ~ 100mm.

On the other hand, the user may use the functional pillow 100 by putting the pillow support 120 in the pillow cover 130, or take out the pillow support 120 from the pillow cover 130 to use the functional pillow 100. Therefore, the user can conveniently use the functional pillow 100 in a desired form, thereby increasing convenience.

11 and 12, the base connecting portion 121 may be omitted. In this case, the pillow cover 130 is tightly wrapped in the pillow body 110 and the pillow support 120 in a state in which the pillow support 120 is in close contact with the lower surface of the pillow body 110, to the pillow body 110 Respective positions of the pillow rests 120 may be maintained.

The pillow bases 120 may be covered by the base cover 122 to be accommodated in the pillow cover 130. Although not shown, the pillow cover 130 may have pockets for respectively receiving the pillow holders 120 to maintain each position of the pillow holders 120. The thickness of the pillow body 110 may be set as thick as the thickness of the support connecting portion 121 is omitted.

As shown in FIG. 13, the pillow rests 120 ′ may be formed to have a distance d ′ that gradually narrows toward each other from the head of the user to the neck. Therefore, the space S between the pillow seats 120 'is smaller than the width of the left and right areas of the area corresponding to the neck side, so that the cushion seat 140 and the pillow body 110 of The left and right parts are deformed to fit the left and right width of the head and neck to wrap the head and neck. Thus, the user can feel more warmth.

The left pillow support 120 ′ may be inclined on the right side to widen the left and right widths from the head to the neck and may be parallel to the left edge of the pillow body 110. The right pillow support 120 ′ may be inclined to the left side so that the left and right widths widen from the head to the neck, and the right side may be parallel to the right edge of the pillow body 110. The left and right widths of the pillow support 120 'may be set to a value within the range of 80 to 100 mm.

Although the present invention has been described with reference to one embodiment shown in the accompanying drawings, this is merely exemplary, and it will be understood by those skilled in the art that various modifications and equivalent other embodiments are possible.
