Functional pillow

More particularly, the present invention relates to a functional pillow, which can comfortably support the neck and head when sleeping in a normal posture, prevent the shoulder palpation and necking even when sleeping on the side (side), and automatically maintain the cervical balance ≪ / RTI >

In general, the importance of relaxation is unquestionably in the fact that it plays an enormous number of roles in the human body such as energy charging, vitality strengthening, growth, regeneration, and strengthening of immunity.

The most common rest in life is sleep. There is no good rest as good quality sleep. Therefore, it is important to sleep well. Actually, sleeping quality has a great effect on room temperature and humidity, but it is important to physically sleep well.

If you use the pillow improperly or do not take your sleeping position properly, it may cause a variety of diseases such as joint neck pain, neck muscle pain, ligament damage, etc. The ideal sleep posture is to make the spine straight (right posture) so that the muscles are not tense.

When lying straight, the neck is naturally kept in a C-shaped curvature, and when lying sideways, it is desirable to put the cervical vertebrae and the thoracic spine in a straight line state so that they do not give a load to the spinal system. Sleeping on the cervical vertebrae after pressing the nerve can cause arm stiffness and shoulder stiffness.

The role of the pillow is also important: it should support the neck while maintaining the normal alignment of the spine, and it should be made of a structure that fits over the various heads. When lying sideways, the height of the pillow should be higher than that of the lying posture, considering the shoulder height.

On the other hand, as a prior art related to a functional pillow, Japanese Laid-Open Patent Publication No. 10-2012-0005893 discloses a laryngoscope comprising: a laryngeal surface portion formed in a shape conforming to an external shape of the larynx; A cervical vertebra which is formed as a curved surface conforming to a curved line of the cervical vertebra when the larynx is placed in the laryngeal portion; And a telescopic space formed by recessing one end of the laryngeal cushion portion so that the size of the laryngeal cuspid portion can be adjusted according to the size of the larynx of the user to be accommodated in correspondence with the laryngeal surface portion. .

In addition, Japanese Patent Application No. 10-0718661 discloses " a body formed of a cushioning material having a predetermined shape and a thickness, a body formed to be curved at a predetermined height so as to support the upper cervical vertebrae on one side of the body, A cervical spine portion including a cervical spine portion and a cervical spine portion, the cervical spine portion including a cervical spine portion and a cervical spine portion; A headrest portion for physiotherapy, which includes an acupressure portion and is inclined and curved from an upper cervical spine portion, has been disclosed.

These conventional prior arts, however, do not have the ability to comfortably support the neck and head when sleeping in a normal posture, to prevent shoulder depression and necking during side sleep, and to automatically maintain cervical balance, There is a problem that it is not possible to prevent the neck and shoulder diseases caused by shoulder joint compression and cervical torsion which are commonly experienced by people.

1 to 8, a functional pillow according to the present invention includes a larynx seat portion 10, a pair of core portions 20, a cervical spine portion 30, and a pair of wing portions 40 ).

The larynx seat part 10 is made of a material having a predetermined shape and thickness and is configured to seat the back of the user on the upper surface. The laryngeal seated part 10 may be formed, for example, in a rectangular shape, and may be formed into a circular or elliptical shape, or a complex shape of a circular shape and a square shape, as the case may be.

A core portion 20 is formed on both sides of the laryngeal seating portion 10 and a cervical vertebra 30 is formed on the upper side. At this time, it is preferable that the laryngeal seating portion 10 is formed at a height approximately midway of the entire height of the core portion 20.

At least one pressure-distributing portion 13 may be formed on the larynx seat portion 10 so that the load pressure due to the user's back portion can be dispersed. For example, the pressure distributor 13 may include at least one line-shaped line formed through the portion adjacent to the cervical vertebrae and at least one line-shaped line spaced apart from the C-shaped line and formed through the line. These lines are designed to distribute the load pressure of the occiput, so that the load pressure of the occiput can be evenly distributed irrespective of the shape of the occiput of the user, thereby maximizing comfort at the time of sleep.

The pressure distributor 13 may be formed in a shape of polygonal, circular, elliptical, or a combination thereof in addition to this shape. Alternatively, the pressure dispersion portion 13 may be formed in a shape of polygonal, circular, elliptical, or a combination thereof. 5 illustrates that the pressure dispersion portion 13 is formed into a square groove.

According to the functional pillow according to the embodiment of the present invention, when the user touches the pillow surface, the load on the specific portion protrudes when the user's back of the pillow touches the pillow, The surface of the laryngeal seated part 10 connected at the middle height of the laryngeal septum 20 disperses the load pressure of the back of the user evenly throughout the laryngeal seated part 10,

In addition, a plurality of perforations (not shown) may be formed on the surface of the laryngeal receiving section 10 to a predetermined size. The perforation (not shown) serves to uniformly distribute the pressure of the occipital region of the user throughout the laryngeal seated part 10 and increases the breathability, thereby allowing the user to feel cool and maximize comfort at the time of sleep.

The functional pillow according to an embodiment of the present invention may further include a first height adjusting pad which can be inserted into a lower space of the laryngeal resting portion.

The first height adjustment pad (not shown) may have a shape corresponding to the shape of the back of the user. That is, to meet an unspecified number of user needs, the shape of the back surface of various users is modeled, and the shape pattern of the top surface of the first height adjusting pad (not shown) is processed to form a plurality of first height adjusting pads It is possible to provide a single set so that it can be used regardless of the shape of the back of the user. At this time, the material of the first height adjusting pad (not shown) may be larger in hardness than the material of the larynx seat part. By increasing the hardness of the first height adjustment pad (not shown), the back of the user corresponding to the formation formed on the first height adjustment pad can feel a sense of stability.

Like the surface of the laryngeal rest part 10, a plurality of perforations (not shown) may be formed on the surface of the first height regulating pad (not shown) to a predetermined size. The perforation (not shown) serves to uniformly distribute the load pressure of the back of the user to the entire first height adjusting pad and the larynx seat 10, and increases the breathability of the user to make the user feel cool, Can be maximized.

The pair of core portions 20 are formed extending from the laryngeal seating portion. At this time, it is preferable that the core part 20 is inclined at a predetermined angle in the laryngeal seating part. That is, when the user is laid in a normal posture, the back of the user is seated on the larynx seat, and when the user is lying on the side, the face of the user is supported by one of the pair of cores, And the seat portion and the pair of core portions are connected by being inclined at a predetermined angle.

The core portion 20 supports the load of the head when the user is asleep. To this end, the upper surface of the core portion 20 may be formed with a recess having a predetermined size to correspond to the face shape of the person (cheek shape).

A space 21 into which the arm can be inserted is formed at both lower ends of the core portion 20 when the user slides sideways and raises the arm at a predetermined angle. Accordingly, it is possible to prevent the pillow from deviating from the proper sleeping position due to the movement of the arm when the user lies sideways while sleeping.

The core end 22 may be formed to protrude upward so as to prevent the face of the user from being detached. In addition, a pad inserting unit (not shown) may be formed at the lower end of the pair of core units 20, for inserting a second height adjusting pad (not shown) capable of adjusting the height of the pair of core units. At this time, the second height adjusting pad may be formed of a material having a hardness higher than that of the pair of core portions.

The cervical vertebra 30 is formed to be connected to the laryngeal seated part 10 and the pair of core parts 20 and is protruded from the laryngeal seated part and connected slantly. Preferably, the cervical vertebrae 30 has a central portion with a lower height than both side portions. By doing so, the user's cervical vertebrae can be stably placed on the cervical vertebrae 30.

At least one groove having a predetermined shape may be formed at a predetermined position of the cervical vertebrae 30 on which the user's cervical vertebrae are placed (see FIG. 2). For example, The grooves may be formed as a 'T' shape 32. Further, for example, the grooves may be a straight shape 34 formed up and down. Also, for example, the grooves may be formed of a combination of the 'T' shape 32 and the straight shape 34.

The cervical vertebrae 30 may be formed in a multi-layer structure formed of two or more materials having different hardnesses. Preferably, the hardness of the lower layer 30b of the cervical vertebrae may be greater than the hardness of the upper layer 30a.

Since the hardness of the lower layer 30b of the cervical spine is greater than the hardness of the upper layer 30a, both a soft feeling and a sense of security can be felt. That is, since the lower layer 30b is relatively hard, it can provide a sense of stability, and the upper layer 30a is relatively less rigid and can provide a soft feeling. The lower layer 30b is sufficiently hard to be able to pull and pull the neck before sleeping. That is, the user can use the pillow upside down before sleeping. At this time, the lower layer 30b is relatively hard, so that the user's neck can be shrunk and pulled.

On the other hand, at least a part of the cervical vertebrae may include a cervical spine portion 31 formed at a hardness greater than the hardness of the upper layer and the lower layer.

The cervical spine portion 31 may be surface-treated with a material having a hardness greater than that of the upper and lower layers, or may be formed by inserting or attaching a material having a hardness greater than that of the upper and lower layers. For example, the cervical spine 31 may be formed by spraying polyurethane to have a relatively greater hardness than other portions of the functional pillow. Alternatively, plastic, metal, wood, or the like having a hardness higher than that of the pillow material may be attached to the lower layer 30b of the cervical vertebra using a predetermined bonding means. Alternatively, it may be formed by inserting and inserting a space into which the plastic, metal, wood or the like can be inserted in the lower layer 30b of the cervical spine.

By forming the cervical spine portion 31 in this way, when the user turns the functional pillow upside down before the sleeping and puts the cervical spine on the cervical spine portion formed on the back surface of the pillow, A pulling (necking) effect can be obtained.

At least one groove (32, 33) may be formed on the upper surface and the lower surface of the cervical vertebra and the laryngeal seat for dispersing the pressure of the cervical vertebrae of the user (refer to FIGS. 6 and 7). (32, 33) can transmit a comfortable feeling by allowing the pillow to be collected toward the user's cervical vertebrae when the user is sleeping. In the case of the user's pre-sleep cervical vertebra, the hard cervical vertebrae (31) Can be improved.

At both ends of the lower layer of the cervical spine 30, a mastoid stone 15 for dispersing a load pressure caused by the neck and the back of the user can be formed. The existing masonry stone (15) distributes the load of the user's neck and head at the time of sleep evenly, thereby maximizing the comfort during sleep.

When the user does not have the masonry stone 15 at both ends of the lower layer of the cervical spine receiving portion 30, both sides of the user's back of the user are pressed by the cervical spine 30 when the user uses the pillow. In order to prevent this, it is possible to reduce the sense of urgency by forming a masonry stone 15 on both ends of the lower layer of the cervical spine 30. By forming the masonry stone 15 on both ends of the lower layer of the cervical spine 30, As a result of the head load of the user, the mastoid stone 15 is opened, thereby maximizing the comfort of the tofu in the seating and further raising both wings. In addition, when the pillow is turned upside down, the existing mollusk stone (15) is clogged and serves to wrap the head well.

The pair of core portions 20 and the cervical vertebrae 30 may have a multi-layer structure composed of two or more materials having different hardnesses, and the hardness of the lower layer may be greater than the hardness of the upper layer. As described above, since the hardness of the lower layer is large and the hardness of the upper layer is small, the front surface of the pillow can be made soft and the rear surface of the pillow can be made relatively hard.

As described above, since the front hardness of the pillow is small and the rear hardness is large, the user can use the rear surface of the pillow for simple acupressure and traction before going to bed.

The pair of wings (40) are inclined upwardly from one side of the pair of core portions, and are inserted between a face and a shoulder of the user when the user is lying on the side to support the face of the user As shown in FIG. Here, the two corner portions 42 of the pair of wings 40, which are not connected to the cervical spine portion, are formed to be longer in an upward direction than a portion connected to the cervical spine portion 30, It is preferable that the end of the wing portion 43 is protruded from the other end. The shoulder of the user is positioned in the space 41 below the wing portion while the front surface of the user is laid on the upper surface of the core portion 20 when the user is laid on the side by protruding the wing portion end 43, The wings 40 can be closely disposed between the face and the shoulder of the wearer's body so as to support the user's face.

 The wing portion 40 is formed so as to extend obliquely, so that a space 41 into which a user's shoulder can be inserted is formed below the wing portion 40. When the user sleeps in an upright normal posture, Can be inserted.

Further, when the user walks with his / her back in a normal posture, the wing portion 40 is naturally positioned between the neck and the shoulder. Thus, it is possible to prevent the user's neck from bending down or bending due to the load. As a result, sleeping sideways can prevent neck and shoulder diseases caused by frequent shoulder compression and cervical twisting.

FIG. 8 shows a state in which a functional pillow according to an embodiment of the present invention is inserted into a vesicle leaf A. FIG.

Next, a method of using the functional pillow according to an embodiment of the present invention will be described with reference to FIGS. 9 to 11. FIG.

FIG. 9 is a view showing the use state of the functional pillow when the user is sleeping in a normal posture in which the user lies downright.

As shown in Fig. 9, when the user is sleeping in a straight posture, the back of the user is seated in the laryngeal seat 10, the user's neck is placed on the cervical spine, And is inserted into a space formed in the lower portion of the housing 40. At this time, the back of the user can be placed on the pressure distributing portion, and the C-shaped line of the pressure distributing portion is moved downward by the load pressure of the occiput portion to disperse the pressure load of the occiput portion. As a result, the user is able to maximize comfort during sleep.

Figs. 10 and 11 are views showing the use state of the functional pillow when the user sleeps in a sideways posture. Fig. 10 is a side view and Fig. 11 is a plan view.

As shown in FIG. 10, the user's face is moved from the laryngeal seated part to the surface of the core part 20 when the user is sleeping in a normal posture and then is turned to a side lying posture regardless of intentional or unintentional The wing portion 40 is naturally positioned between the user's neck and shoulder. Thus, it is possible to prevent the user's neck from bending down or bending due to the load. As a result, sleeping sideways can prevent neck and shoulder diseases caused by frequent shoulder compression and cervical twisting.

According to the functional pillow of the present invention as described above, the neck and head can be comfortably supported when sleeping in a normal posture, the shoulder squeezing and necking can be prevented even at the side sleep, and the cervical vertebra can be automatically maintained.

In addition, there is an advantage in preventing the neck and shoulder diseases caused by shoulder pressure and cervical torsion, which are often experienced by people who are lying sideways, by preventing shoulder depression and necking even when sleeping on the side.

Further, if the user reverses the pillow before sleeping and puts the cervical spine on the cervical spine portion formed on the back surface of the pillow, the user can obtain the pulling effect of the spinal pressure and the cervical spine by the hard portion of the cervical spine portion.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is clearly understood that the same is by way of illustration and example only and is not to be taken by way of limitation in the embodiment in which said invention is directed. It will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the scope of the appended claims.
