Description

  The present invention relates to a pillow, and more particularly, to a pillow including a neck side portion that supports the neck side and a parietal side portion that supports the parietal side.

  Conventionally, as this kind of pillow, for example, what is published in Patent Document 1 (Act No. 3119581) is known. As shown in FIG. 8, this pillow Ma connects the neck side part 100 which supports a neck side, and the parietal side part 101 which supports a parietal side, and forms the horizontal width Xa longer than the vertical width Ya. . Each of the neck side portion 100 and the parietal side portion 101 has an upper surface 102 on which the neck portion or the crown portion is placed, and a lower surface 103 that is grounded to the ground surface. Further, the upper surface 102 has a longitudinal width Ya direction cross section formed in an arc shape, and the lower surface 103 has a vertical width Ya direction cross section formed in a straight line horizontal to the ground plane. In this pillow Ma, the distance L1, L2 between the ridge line 104 of the upper surface 102 extending in the width Xa direction and the underline where the perpendicular of the ridge line 104 intersects the lower surface is the width L They are formed substantially the same in the Xa direction. Further, the pillow Ma is formed with a head receiving recess 105 into which a part of the head enters a central portion in the width Xa direction, which is a connecting portion between the neck side portion 100 and the parietal side portion 101. .

  When the pillow Ma thus formed is used, the neck portion is supported by the upper surface 102 of the neck side portion 100, and the head top portion is supported by the upper surface 102 of the parietal side portion 101. In particular, when the head is placed on the center of the width direction Xa of the pillow Ma and sleeping in the supine position, a part of the back of the head enters the head receiving recess 105, so that the neck or the top of the head is properly Therefore, the burden on the neck is reduced, the burden on the cervical spine is reduced, and a comfortable sleep can be obtained.

Santo No. 3119581

  However, in this conventional pillow Ma, since the back of the head enters the head receiving recess 105 and is supported in the supine position, it is difficult to turn over from the supine position to the lying position. In addition, when the body position shifts from the supine position to the recumbent position, when the body position shifts to the recumbent position, the part of the head that contacts the upper surface 102 of the pillow Ma changes from the occipital region to the temporal region. Since the distances L1 and L2 between the vertical line 104 and the underline where the perpendicular line of the ridge line 104 intersects the lower surface are formed substantially the same in the horizontal width Xa direction, the thickness and shape of the neck side portion 100 and the parietal side portion 101 are also in the lateral position. However, there is a problem that the support stability of the neck or the top of the head in the lying position is not sufficient and comfortable sleep cannot be obtained. Further, when the body position is changed from the supine position to the recumbent position, the shape of the neck or the top of the head in contact with the upper surface 102 in the supine position is largely uneven, but the shape of the neck or the top of the head in contact with the upper surface 102 when in the recumbent position Becomes substantially flat, and the shape of the neck or the top of the head in contact with the upper surface 102 changes. In this case, since the cross section in the vertical width Ya direction of the lower surface 103 is formed in a straight line horizontal to the ground surface, The neck side part 100 and the head side part 101 cannot follow and support in response to a change in the shape of the neck part or the head part in contact, and in this respect also, the support stability of the neck part or the head part at the time of lying down is achieved. There was a problem that it was not sufficient and comfortable sleep could not be obtained.

  The present invention has been made in view of such problems, and it is intended to provide a pillow that can provide a comfortable sleep by stabilizing the support of the neck or the top of the head not only in the supine position but also in the lying position. Objective.

  In order to achieve such an object, the pillow of the present invention connects the neck side part supporting the neck side and the parietal side part supporting the parietal side, and in the pillow formed with the lateral width longer than the vertical width, The neck side part and the parietal side part are formed in a substantially elliptical shape whose longitudinal section is vertically symmetric with respect to the center line in the longitudinal direction, and is continuous in the lateral area in the central area and to the left and right of the central area, respectively. The thickness between the upper and lower ridge lines extending in the lateral width direction in each area is formed to be substantially the same, and the parietal side portion side of the central area of the neck side portion is on the parietal side portion side. And forming a recess into which the convex portion enters the neck side portion side of the central area of the parietal side portion, on the parietal side portion side passing through the center line of the neck side portion. Neck side edge in the width direction and the neck side part passing through the center line of the parietal side part Are connected with a band-shaped connecting member, the thickness of the central area of the neck side portion is H1, the thickness of the side area of the neck side portion is H2, and the top of the head Each area is formed such that H1> H2> H3> H4, where H3 is the thickness of the side area on the side and H4 is the thickness of the central area on the side of the top of the head.

  Thereby, when the pillow of the present invention is grounded to the ground plane, the ridge line below each of the areas on the neck side and the top side is grounded to the ground plane, and the connecting member is not grounded to the ground plane. That is, an arc surface extending from the lower ridge line of each area to the connecting member and a lower surface space surrounded by the connecting member and the grounding surface are formed on the lower surface on the ground contact surface side. In this state, the user sleeps by placing the neck or the crown on the upper surface opposite to the lower surface.

  In the supine position, the neck or the top of the head is placed in the central area of the neck side and the top of the head. As a result, the neck portion is supported on the upper surface of the neck side portion, and the parietal portion is supported on the upper surface of the parietal side portion. The central area of the neck side part is formed with a substantially elliptical cross section in the longitudinal width direction, and has a convex part, the thickness H1 of the central area of the neck side part is the thickest, and the central area of the parietal side part Since the thickness H4 is formed to be the thinnest, the back of the head is placed on the convex part, and the user will lie in a posture that protrudes the chin, so the airway is widened and breathing during sleep is easy Can be done. In addition, since the upper surface fits to the neck or the top of the head, the support of the neck or the top of the head is stable, so that it is possible to obtain a feeling of use as if the heel is wearing a knee pillow and to obtain a comfortable sleep. .

  Further, when the body position is shifted from the supine position to the lying position, the head portion placed on the upper surface changes from the occipital region to the temporal region. That is, the shape of the neck or the top of the head in contact with the upper surface in the supine position is largely uneven, but the shape of the neck or the top of the head in contact with the upper surface in the lying position is substantially flat, and the shape of the neck or the head in contact with the upper surface is substantially flat. The shape changes. In this recumbent position, the neck or the top of the head is placed on either the left or right side area of the neck side or the top of the head. At this time, the neck side part on the side where the neck part or the top part is placed and the side part area on the top part of the head part are pressed by the weight of the head, the arc surface from the upper ridge line to the connecting member is pressed, The connecting member moves toward the ground plane, and the lower surface space is crushed. Specifically, the neck side edge and the parietal side edge move together with the connecting member to the ground plane, and the center line is inclined with respect to the ground plane along with this, so the neck side and the parietal side The part rolls with the connecting member as a fulcrum. In other words, even if the shape of the neck or the top of the head in contact with the top surface changes, such as when lying down, the neck side and the top of the head will automatically follow and support correspondingly. The upper surface surely fits to the neck or the top of the head, so that the support of the neck or the top of the head is stable, and it is possible to obtain a feeling of use as if the heel is also a knee pillow, and to obtain a comfortable sleep it can.

The thickness H3 is set to 35 mm to 65 mm, and the thickness H4 of the central area of the parietal side is set to 30 mm to 50 mm. Although the physique and the size of the head differ depending on the user, versatility is improved by setting the thickness of each area within the above range. In addition, by setting the thickness of each area within the above range, the support of the neck or the top of the head can be further stabilized in the supine position and the lying position, and a more comfortable sleep can be obtained. . Furthermore, by making the thickness H1 of the central area of the neck side portion and the thickness H2 of the side area of the neck side portion correspond to each other as described above, the body position can be smoothly changed from the supine position to the lying position. Therefore, for example, even if the body position is changed from the supine position to the lying position during sleep, there is no sense of incongruity and awakening, so that a more comfortable sleep can be obtained.

  Further, if necessary, the maximum length A1 of the central area of the neck side portion in the vertical width direction is set to 120 mm to 248 mm, and the maximum length A2 of the side area of the neck side portion is set to 150 mm to 186 mm. The maximum length A3 in the vertical width direction of the side area on the parietal side portion is set to 100 mm to 124 mm, and the minimum length A4 in the vertical width direction of the central area on the parietal side portion is set to 50 mm to 62 mm. Although the physique and the size of the head differ depending on the user, versatility is improved by making the maximum length in the vertical width direction of each area within the above range. In addition, by making the length in the vertical width direction of each area within the above range, the support of the neck or the top of the head can be further stabilized in the supine position and the lying position, and more comfortable sleep can be achieved. Can be obtained. Furthermore, by setting the maximum lengths A2 and A3 in the vertical width direction of the side area of the neck side part and the top side part within the above range, when the head is in the recumbent position, the head is separated from the upper ridge line. The arc surface leading to the connecting member is more surely pressed, whereby the neck side portion and the parietal side portion are more reliably rolled, so that the neck side portion and the parietal side portion are connected to the neck portion or the crown portion. It automatically follows and supports, so that the support of the neck or the top of the head is further stabilized, and a more comfortable sleep can be obtained.

  Further, if necessary, the lateral width B of the neck side part and the top side part is formed to be 500 mm to 600 mm, the length of the central area of the neck side part in the lateral width direction is B1, and the side area of the neck side part B1 = B2 where B2 is the length in the width direction of the head, the length in the width direction of the side area on the parietal side is B3, and the length in the width direction of the central area on the parietal side is B4. Each area is formed so that = B3 = B4 = (1/3) · B. Although the physique and the size of the head differ depending on the user, versatility is improved by making the length in the width direction of each area within the above range. In addition, by setting the length in the width direction of each area within the above range, the support of the neck or the top of the head can be further stabilized in the supine position and the recumbent position, and more comfortable sleep can be obtained. be able to. Furthermore, when the lengths B1 and B4 in the width direction of the central area of the neck side part and the top side part are within the above range, when the body position is shifted from the supine position to the lying position, the neck or head The top part is surely placed by the side area of either the neck side or the top side of the head, so that even when lying down, the neck or top of the head is reliably supported in the side area.

As a result, the neck portion is supported on the upper surface of the neck side portion, and the parietal portion is supported on the upper surface of the parietal side portion. The central area of the neck side part is formed with a substantially elliptical cross section in the longitudinal width direction, and has a convex part, the thickness H1 of the central area of the neck side part is the thickest, and the central area of the parietal side part Since the thickness H4 is formed to be the thinnest, in the supine position, the occipital region is placed on the convex portion, and the user lies in a posture that projects the jaw, so that the airway is widened, Easily breathe during sleep. In addition, since the upper surface fits to the neck or the top of the head, the support of the neck or the top of the head is stable, so that it is possible to obtain a feeling of use as if the heel is wearing a knee pillow and to obtain a comfortable sleep. .

  Further, when the body position is shifted from the supine position to the lying position, the head portion placed on the upper surface changes from the occipital region to the temporal region. That is, the shape of the neck or the top of the head in contact with the upper surface in the supine position is largely uneven, but the shape of the neck or the top of the head in contact with the upper surface in the lying position is substantially flat, and the shape of the neck or the head in contact with the upper surface is substantially flat. The shape changes. In this recumbent position, the neck or the top of the head is placed on either the left or right side area of the neck side or the top of the head. At this time, the neck side part on the side where the neck part or the top part is placed and the side part area on the top part of the head part are pressed by the weight of the head, the arc surface from the upper ridge line to the connecting member is pressed, The connecting member moves to the ground plane, and with the movement of the connecting member, the neck side edge and the crown side edge move to the ground plane, so that the center line is inclined with respect to the ground plane. Therefore, the neck side portion and the crown side portion roll with the connecting member as a fulcrum. In other words, even if the shape of the neck or the top of the head in contact with the top surface changes, such as when lying down, the neck side and the top of the head will automatically follow and support correspondingly. The upper surface surely fits to the neck or the top of the head, so that the support of the neck or the top of the head is stable, and it is possible to obtain a feeling of use as if the heel is also a knee pillow, and to obtain a comfortable sleep it can.

Therefore, when the pillow M according to this embodiment is used, the following effect is obtained.
First, the pillow M of the present invention is grounded on the ground plane. At this time, the surface on which the flexible member 8 coated with tourmaline is not accommodated is grounded to the ground surface. When grounded, the ridge lines 3 and 12 below the areas 1a, 1b, 10a, and 10b of the neck side portion 1 and the parietal side portion 10 are grounded to the ground plane, and the connecting member 20 is grounded to the ground plane. do not do. That is, the lower surfaces 7 and 16 on the ground plane side are surrounded by the arc surfaces extending from the ridge lines 3 and 12 on the lower side of the areas 1a, 1b, 10a, and 10b to the coupling member 20, and the coupling member 20 and the ground plane. A lower surface space 30 is formed. In this state, the user sleeps by placing the neck or the crown on the upper surfaces 6 and 15 opposite to the lower surfaces 7 and 16.

  In the supine position, as shown in FIG. 6, the neck part or the top part is placed on the central areas 1 a and 10 a of the neck side part 1 and the parietal side part 10. As a result, the neck portion is supported on the upper surface 6 of the neck side portion 1, and the crown portion is supported on the upper surface 15 of the parietal side portion 10. The central area 1a of the neck side portion 1 is formed in a substantially elliptical shape in the longitudinal width A direction and has a convex portion 4, and the thickness H1 of the central area 1a of the neck side portion 1 is the thickest, Since the thickness H4 of the central area 10a of the parietal side portion 10 is formed to be the thinnest, the occipital region is placed on the convex portion 4 and the user lies in a posture of projecting the chin so that the airway is It is spread out and can easily breathe during sleep. In addition, since the upper surfaces 6 and 15 are fitted to the neck or the top of the head, the support of the neck or the top of the head is stable, so that it is possible to obtain a feeling of use as if the heel is also a knee pillow and to obtain a comfortable sleep. be able to.

  Further, although the physique and the size of the head are different depending on the user, the thickness H1 of the central area 1a of the neck side portion 1, the maximum length A1 in the vertical width direction, and the length B1 in the horizontal width direction are within the above ranges. Since the thickness H4 of the central area 10a of the parietal side portion 10 and the minimum length A4 in the vertical width direction and the length B4 in the horizontal width direction are formed within the above ranges, the neck portion can be further increased in the supine position. To stabilize the support of the top of the head and obtain a more comfortable sleep, the back of the head is reliably placed on the convex part 4, and the user comes to supine in a posture that protrudes the chin, Versatility is improved.

  Then, when the body position is shifted from the supine position to the recumbent position during sleep, the head portion placed on the upper surfaces 6 and 15 changes from the occipital region to the temporal region as shown in FIG. That is, the shape of the neck or the top of the head in contact with the upper surfaces 6 and 15 in the supine position is largely uneven, but the shape of the neck or the top of the head in contact with the upper surfaces 6 and 15 in the lying position becomes substantially flat, and the upper surface 6 , 15 changes the shape of the neck or the top of the head. In this recumbent position, the neck part or the top part of the head is placed on either the left or right side area 1b, 10b of the neck side part 1 and the top side part 10. At this time, since the lengths B1 and B4 of the central areas 1a and 10a of the neck side portion 1 and the parietal side portion 10 are formed within the above range, the body is placed in the lying position by turning over from the supine position. The head or the top of the head is securely placed by the side area 1b or 10b of either the neck side part 1 or the head side part 10, so that even when lying down, The neck area or the top of the head can be reliably supported by the head areas 1b and 10b. When lying in the recumbent position, the side area 1b, 10b of the neck side 1 on the side where the neck or the top of the head is placed and the side area 1b, 10b of the top side 10 are determined by the weight of the head. The arc surface from 12 to the connecting member 20 is pressed, the connecting member 20 moves to the grounding surface side, and the lower surface space 30 is crushed. Specifically, the neck side edge 5 and the crown side edge 14 move to the grounding surface side together with the connecting member 20, and accordingly, the centerlines 2 and 11 are inclined with respect to the grounding surface. The side areas 1b and 10b of the neck side part 1 and the top side part 10 roll with the connecting member 20 as a fulcrum. As the side areas 1b and 10b roll, the central areas 1a and 10a of the neck side 1 and the top side 10 also roll with the connecting member 20 as a fulcrum. That is, when the shape of the neck or the top of the head in contact with the upper surfaces 6 and 15 changes, such as when lying down, the neck side 1 and the top of the head 10 automatically follow and support correspondingly. Therefore, the upper surfaces 6 and 15 are securely fitted to the neck or the top of the head, so that the support of the neck or the top of the head is stable, and a feeling of use as if the heel is also a knee pillow can be obtained. You can get a comfortable sleep.

  Although the physique and the size of the head are different depending on the user, the thickness H2 of the side area 1b of the neck side portion 1, the maximum length A2 in the vertical width direction, and the length B2 in the horizontal width direction are within the above ranges. Since the thickness H3 of the side area of the parietal side portion 10, the maximum length A3 in the vertical width direction, and the length B3 in the horizontal width direction are formed within the above-described ranges, The top of the head more reliably presses the arc surface from the upper ridge lines 3, 12 to the connecting member 20, so that the neck side 1 and the top of the head 10 roll more reliably. Therefore, the neck side part 1 and the parietal side part 10 come to automatically follow and support the neck part or the top part of the head, and therefore, the support of the neck part or the top part of the head is further stabilized, thereby making sleep more comfortable. It can be obtained and versatility is improved.

  Further, the lateral widths B2 and B3 of the side areas 1b and 10b of the neck side part 1 and the parietal side part 10 are formed within the above range, so that the body is placed in the lying position by turning over from the supine position. , The neck portion or the top portion does not protrude from the side areas 1b and 10b, and therefore the neck portion or the top portion can be reliably supported by the side areas 1b and 10b. Furthermore, the posture shift from the supine position to the recumbent position is achieved by making the thickness H1 of the central area 1a of the neck side part 1 and the thickness H2 of the side area 1b of the neck side part 1 as described above. For example, even if the body position changes from the supine position to the lying position during sleep, the user does not wake up feeling uncomfortable, and therefore, a more comfortable sleep can be obtained.

  Further, when the neck or the top of the head is placed on the upper surfaces 6 and 15 in the supine position and the lying position, the flexible member 8 coated with tourmaline is accommodated on the upper surface 6 side of the neck side portion 1. Therefore, an external force is applied to the tourmaline depending on the weight of the neck or the top of the head, and negative ions are generated. Many negative ions are present in forests, coasts, etc., and are generally known to have a positive effect on the body and mind. Therefore, when the pillow M of the present invention is used, it is possible to enjoy the refreshing feeling of forest bathing, to feel refreshed, to improve sleeping comfort, and to obtain a comfortable sleep. As a result, it is extremely good for the body and mind, and is extremely effective for improving the health of the mind such as restoring health and relieving stress. Furthermore, tourmaline has a high ability to generate negative ions, and can efficiently generate negative ions. Furthermore, since tourmaline emits far-infrared rays, when it is used for the pillow M, heat can penetrate into the human body without increasing the temperature of the head so that comfort by warmth can be obtained. it can. For this reason, it is possible to contribute to the improvement of the health by the thermal effect such as improving blood circulation of the human body and taking fatigue and stiffness of muscles.

In addition, in the said embodiment, although the neck part 1 and the parietal part 10 were comprised with the cotton blend of cotton and polyester, it is not necessarily limited to this, What is necessary is just a material which has moderate elasticity. It can be changed as appropriate. For example, in addition to cotton and polyester, materials such as silk and wool can be used. These materials may be used alone, or may be a mixture of these materials.
Moreover, in the said embodiment, although the flexible member 8 was formed in the rectangular strip shape, it is not necessarily limited to this, What kind of shape may be sufficient and can change suitably.
Furthermore, in the said embodiment, although the flexible member 8 was formed in said magnitude | size, it is not necessarily limited to this, The magnitude | size accommodated in the neck side part 1 should just be sufficient, and it changes suitably. It doesn't matter.
Furthermore, in the above embodiment, tourmaline is powdered, and a solution in which it is dissolved is applied to the flexible member 8 and then dried. It suffices if tourmaline is stored in 1 and can be changed as appropriate.
