The present invention relates to a high and low pillow, more specifically, by changing the height according to the support of the human body to protect the cervical spine of the user and at the same time changing the sleeping posture, the height of the pillow to provide a comfortable sleep naturally It is about.

The pillow supports the head at bedtime or at rest and induces a good night's sleep, and also secures the stability of the body structure through cervical spine protection and performs a function of smoothing breathing and blood circulation.

However, the normal pillow is a shape that supports the head and the neck of the head with a different height when lying upright when looking up, and serves to push the neck forward, so that even the function of simple bedding cannot be performed properly. Not only do they induce deep sleep during the third-thirds of sleep, but they also tend to harm your health.

In other words, the general pillow does not take into account the characteristics of the body at all, it is very uncomfortable because it has a nearly constant height and a typical form, even if the difference in the distance from the ground to the shoulder and head when lying on the side and lying sideways .

In addition, the pillow is simply put a cushion material such as buckwheat, buckwheat, cotton, rice bran, crest. Therefore, the head, neck and shoulder posture is often unnatural due to the inappropriate height and shape of the pillow when a person sleeps. Due to this, the neck, shoulder or waist may be constipated after sleep, and neck discs, stiff shoulders and waist discs may develop. If the cushion material in the pillow is too hard and the head is pressed, the blood flow in the cervical spine is smooth. Because of the lack of oxygen supply to the brain, even after sleeping, the head is bruised, and in severe cases, the pressure of the cerebral blood vessels is increased, and there is a risk of causing brain hemorrhage or stroke.

In light of the above, the present applicant has proposed a protection pillow for cervical vertebra and shoulder stiffness in Korean Patent Application No. 10-2004-0013922. The present invention further improves the pillow according to the prior art as described above.

An object of the present invention is to provide a high and low pillow that can accommodate a variety of sleeping postures of the user to provide a comfort when sleeping by accepting a natural sleeping posture when the human body is lying down and lying sideways.

Another object of the present invention to provide a pillow that can easily adjust the hardness of the filler embedded in the pillow.

Still another object of the present invention is to provide a pillow having a compact structure and preventing the user's face from slipping out of the pillow.

Height and height pillow according to the present invention for achieving the above object is provided with a flexible endothelial member configured in the shape of a bag to provide a filling space in which the filler is filled with a substantially rectangular shape on a plane. By joining the upper and lower surfaces of the endothelial member in the rectangular central portion of the pillow, the upper portion, the lower portion and the central portion, and the human body, which respectively support the neck and head when the human body lays straight on the inner space of the endothelial member. When lying sideways, it is divided into the left side and the right side supporting the right side and left side of the face. The square center portion is provided with a head support member for elastically supporting the head of the human body. Fillers of different hardness are injected into the upper portion, the lower portion, the left portion, and the right portion. The upper portion and the lower portion have a height greater than that of the center portion and are set to a height smaller than the left portion and the right portion.

The upper part, the lower part, the left part and the right part are configured to communicate with each other, and a first filler is injected, and at least one of the upper part and the lower part is filled with a filler bag containing a second filler having a different hardness from the first filler. Is preferably installed.

In addition, the filler is composed of a plurality of chips having a hollow cylindrical or hollow spherical shape of the upper and lower portions, it is preferable to adjust the hardness by setting the thickness of the chips differently.

In addition, the hardness of the filler is preferably adjusted by adjusting the content ratio of hard chips and soft chips of a specific thickness.

In addition, the tension member for interconnecting the upper and lower surfaces of the endothelial member is preferably further provided.

It is also desirable to join at least a portion of the endothelial member along the vertical direction to the four corner portions of the pillow.

Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the pillow according to the present invention.

1 to 4 show one embodiment of a pillow according to the invention. As shown, the pillow 10 according to the present embodiment includes a flexible endothelial member 11 having a substantially rectangular shape on a plane. The inside of the flexible endothelial member 11 is configured in a bag shape to provide a filling space in which the filler is filled, and is formed by joining the upper surface 11a and the lower surface 11b along the edges. The flexible endothelial member 11 may be implemented as a mesh member, in which case the mesh lattice is preferably set smaller than the particle size of the filler. The said endothelial member can also be manufactured using textile paper other than a mesh-shaped member.

The upper surface 11a and the lower surface 11b are bonded to each other near the rectangular center portion A of the endothelial member 11. That is, two joining lines 13c and 13d are formed along the height direction of the endothelial member 11, and two joining lines 13a and 13b are formed along the longitudinal direction of the endothelial member 11. The joining lines 13c and 13d in the height direction are formed over the entire height of the endothelial member 11, and the joining lines 13a and 13b in the longitudinal direction are formed by a length corresponding to the rectangular center portion A. As shown in FIG. Therefore, the inner space of the endothelial member 11 is divided into the rectangular center part A, its upper part B, the lower part C, the left part D, and the right part E, respectively, in plan view.

The upper portion (B) and the lower portion (C) is a portion that supports the neck when the human body is lying down straight. The central portion (A) is a portion that supports the head when the human body is lying down straight. The left part D and the right part E are parts supporting the right part and the left part of the side surface of the face when the human body is lying sideways. Therefore, the height of the upper portion (B) and the lower portion (C) is set higher than the height of the center portion (A), it should be set lower than the height of the left portion (D) and the right portion (E).

The upper portion (B) and the lower portion (C) is set to have a length, width and height of the degree that can give the effect of pressure on the cervical spine by supporting the neck when the human body is lying down straight.

The head support member 15 for elastically supporting the user's head is installed between the upper surface 11a and the lower surface 11b of the endothelial member of the rectangular center portion A so that the user feels the head comfort when lying down. To do that. The head support member 15 may be inserted into the chip used as a cushion material or filling material using cotton.

The left portion D and the right portion E of the upper surface 11a of the endothelial member 11 further include a face support member 12 made of a soft material that elastically supports the side surface of the user's face when the human body is laid on its side. It is prepared. The face support member 12 performs a function of preventing the stretching of the mesh-type endothelial member 11. The left part D and the right part E are long enough to support the side of the face when the human body is lying sideways (length larger than the size of the human head) and height (from the outside of the shoulder to the side of the face). Interval).

As shown in Fig. 7, the user lays straight and supports the neck on the upper part (B) and the lower part (C), and rotates the body by 90 ° to the left and right sides with the head supported by the center part (A). In addition, the user should have a length that can be easily changed to a sleeping posture in a lying state, and at the same time, the user should have a height such that the shoulders are not stiff in a state of lying on the side.

Fillers having different hardnesses are injected into the upper portion B, the lower portion C, the left portion D, and the right portion E. Hereinafter, the fillers will be described.

Since the left part D and the right part E must elastically support the side surface of the human body, soft fillers 20d and 20e are injected. 5A and 5B, the filler 20 is composed of a plurality of chips having a hollow cylindrical shape having upper and lower portions, and the hardness of the filler is adjusted by setting the thickness t of the chips differently. do. Hard chips having a relatively thick thickness are hard, but have weak restoring force and are brittle, and are mainly manufactured using polypropylene. On the other hand, a relatively thin thickness of the soft chip has a weak brittleness, softness and good restoring properties, mainly made of polyethylene (polyethylene) material.

That is, the soft fillers 20d and 20e injected into the left portion D and the right portion E use chips having a relatively thin thickness.

Meanwhile, the fillers 20b and 20c injected into the upper part B and the lower part C should use the hard filler because the human body should give the cervical spine effect when the human is lying down. Hard fillers can be achieved by injecting chips of relatively thick thickness. On the other hand, by setting the hardness of the chip of the filler 20b injected into the upper portion (B) and the filler 20c injected into the lower portion (C) differently, it is possible to maximize the acupressure effect according to the user's preference. .

In order to control the hardness of the filler, the thickness of the chip may be set differently as described above. Alternatively, the overall hardness of the filler may be adjusted by mixing hard or soft chips having a specific thickness and adjusting the content ratio of the hard and soft chips. It is also possible to adjust. For example, in order to increase the hardness of the filler, the content ratio of the hard chips in the mixed chips is greater than the content ratio of the soft chips, and in order to reduce the hardness of the filler, the content ratio of the hard chips in the mixed chips is greater than the content ratio of the soft chips. Set it small.

Meanwhile, as shown in FIGS. 6A and 6B, the filler may be formed of a plurality of hollow spherical chips 20 ′ having upper and lower portions respectively opened. The filler chip 20 'according to the present embodiment has a more elastic chip because the volume of the inner hollow portion is maximized with respect to the entire volume. Similarly to the chips shown in Figs. 5A and 5B, the chip 20 'of the present embodiment can of course be adjusted in hardness by varying the thickness t'.

Reference numeral 19a denotes a zipper for injecting or extracting the fillers 20d, 20c, and 20e into the left portion D, the lower portion C, and the right portion E, respectively, and the reference numeral 19b denotes the filler (the upper portion B). 20b) is a zipper for injecting or ejecting.

Although not shown, a breathable sachet containing a fragrance-releasing material is installed on the outer surface of the pillow. The sachet bag is installed at a position not to be in direct contact with the face or head of the human body but not in contact with the floor on which the pillow is placed, that is, at the left and right edges of the bottom surface 11b of the endothelial member 11. desirable. The fragrance-releasing material can be used a variety of materials, including dried chrysanthemum flowers, herbs.

The pillow of the embodiment shown in Figures 1-4 can be folded along two seams 13c, 13d in the height direction (see Figure 13), thus providing the advantage of minimizing the volume during storage or transportation. . In addition, it is easy to transport and can be used while carrying, and it is easy to carry even when traveling for a long time. In addition, it can be folded and used when a high height pillow is preferred according to the user's preference.

8 to 10 show another embodiment of a pillow according to the invention. As shown, unlike the pillow 10 of the embodiment shown in FIGS. 1 to 4, the pillow 30 according to the present embodiment forms four joint lines 33 along the edge of the rectangular center portion A. As shown in FIG. Therefore, the center portion A is completely isolated from the other portion, while the upper portion B, the lower portion C, the left portion D, and the right portion E communicate with each other.

A flexible first filler 40 is injected into the inner spaces of the upper portion B, the lower portion C, the left portion D, and the right portion E. As described above, the first filler 40 is formed of a relatively thin cylindrical or spherical soft chip.

On the other hand, in order to pressure the cervical spine when the human body is lying down directly, at least one of the upper portion (B) and the lower portion (C) is a filler bag containing a hard second filler 42 having a different hardness from the first filler 41 is installed. The second filler 42 may be a cylindrical or spherical chip having a relatively thick thickness. As shown in Figure 9, the length of the filler bag 41 is formed slightly longer than the upper portion (B) and the lower portion (C), even if the bag flows somewhat in the longitudinal direction in the installation space (B) ) And the lower side (C) is preferably sufficient to cover.

The pillow according to the present embodiment provides an advantage of alleviating the inconvenience of having to divide the filler filling space into four and inject the filler having a specific hardness therein, as compared with the embodiment shown in FIGS. 1 to 4. do. In other words, according to the present embodiment, the soft filler 40 having a specific hardness is filled in the inner space of the endothelial member 31 as a whole, and then the pocket 41 having the hard second filler 42 embedded therein It is sufficient to perform only the work of installing on the upper side (B) and / or the lower side (C).

Reference numeral 35, which is not described in this embodiment, is a head support member that elastically supports the user's head when the human body is lying down, and reference numeral 32 elastically supports the side of the user's face when the human body is lying on the side. The face support member is made of soft material. Reference numeral 38 is a zipper for injecting or ejecting the first filler 40 and the filler bag 41 into the inner space of the endothelial member 31.

11 and 12 show another embodiment of a pillow according to the invention. Pillow 50 according to this embodiment is characterized in that the tension member 60 is further provided to connect the upper surface (51a) and the lower surface (51b) of the mesh member 51 in the vertical direction. That is, the ends 60a and 60b of the flexible tension member 60 are joined to the upper surface 51a and the lower surface 51b of the endothelial member 51 at the center of the left side portion D and the right side portion E, respectively. . Accordingly, the tension member 60 functions to control the endothelial member 51 to be convexly expanded to the outside by the injection of the filler 65. The tension member 60 may function as a pillar or a wall for dividing the filler interior space.

According to the above structure of this embodiment, as shown in Fig. 12, the filler is filled so that the left portion D and the right portion E form a relatively flat surface without convexly bulging in an arc shape, so that the user When lying down, the side surface of the face is prevented from slipping down from the left side and the right side. Therefore, it is not necessary to form the left side and the right side longer than necessary to prevent the fall of the face, it provides an advantage that the structure of the pillow more compact.

Another feature of the present embodiment is to form a junction Y in which at least a portion of the endothelial members 51a and 51b are joined along the vertical direction at four corner portions X of the pillow. According to the above structure, since the density of the filling material reduces the space of the corner portion having a relatively low density, the angle of the corner portion is maintained, which not only enhances the ability to constantly fix and maintain the height of the pillow, but also the user's head on the left side and the right side. Even when the part is pressurized, it is possible to minimize the deformation of the pillow by preventing the flow of the filler. In addition, when the filler bag 41 of the embodiment illustrated in FIGS. 8 to 10 is embedded, the filler 40 at the edge portion of which the density is kept high provides an advantage of preventing excessive flow of the filler bag.

The matters described in this specification and the drawings are presented by way of example to illustrate the embodiments of the present invention, and it should be understood that the protection scope of the present invention is not limited to these matters.

By varying the height according to the height of the support portion according to the present invention protects the cervical spine of the user and at the same time provides a benefit that can naturally accommodate this even if the sleeping posture changes to provide a comfortable sleep. That is, when the human body is lying down, the upper and lower parts of the height suitable for the neck height in which the hard filler is injected are pressed by the cervical spine of the human body, and when the human body is lying on the side, it is suitable for the shoulder height in which the soft filler is injected. The left side and the right side of the height can elastically support the side of the face to prevent shoulder stiffness. In addition, according to the present invention, by adjusting the thickness of the chip or by adjusting the content ratio of the soft chip and the hard chip, the user can easily adjust the hardness of the filler embedded in the pillow to maximize the user's convenience. In addition, the left side and the lower side can be formed flat by the tension member, which provides an advantage in that the user's face does not slip out of the pillow while having a compact structure.
