[0001] The utility model relates to a pillow with different thicknesses. Background Art
[0002] Korean Patent Office Patent Publication No. 10-2021-0093593 (2021.07.28) is used as background technology, such as Fig. 22 As shown, the multifunctional pillow 1 is composed of a head support part 10 and a support part 20 , wherein the head support part 10 has a predetermined thickness between the upper surface 12 and the lower surface 14 , and the support part 20 is integrally formed on the left and right sides of the head support part 10 to support the head support part 10 .
[0003] The support portion 20 is configured such that one side thereof is connected to the head support portion 10 , and an upper end 22 and a lower end 24 protrude from an upper surface 12 and a lower surface 14 of the head support portion 10 by a predetermined height, respectively.
[0004] In addition, reference numeral 15 is an opening and closing opening formed on the front surface or the rear surface of the head support portion 10, and as shown in the figure, it is composed of a zipper or Velcro, etc., and reference numeral 25 is an opening and closing opening formed on the outer side of the support portion 20, and as shown in the figure, it is also a structure that can be opened and closed and is composed of a zipper or Velcro, etc.
[0005] Although the support portion 20 has an elliptical cross-sectional shape, it is not limited thereto and can be made into a circular cross-sectional shape. The upper end 22 and the lower end 24 of the support portion 20 are respectively formed to have different protrusion heights from the upper surface 12 and the lower surface 14 of the head support portion 10.
[0006] The thickness of the head support part 10 is greater than or equal to 5 cm and less than or equal to 10 cm, preferably 6 to 8 cm, and the height of the support part 20 is 10 to 15 cm from the upper end to the lower end.
[0007] Therefore, even if the body including the head is placed on the head support part 10, the support parts 20 on both sides can prevent the body from tilting to either side. When the pillow 1 is turned upside down, the upwardly protruding upper end 22 and the lower end 24 are tilted toward the inside and the outside respectively, so that the head or other body can be effectively supported from the side.
[0008] In addition, although the head support part 10 and the support part 20 can also be formed in a form connected to each other, it is preferably composed of a compartment separated by a partition wall, and by filling them with fillers of different materials, they are selected according to the inherent functions of each part. That is, since the head support part 10 is a part that is in direct contact with the human body, a material with a cushioning feeling that each user likes is selected, and since the degree to which the support part 20 is compressed due to the weight of the head is particularly important, sponges or memory foams with different compression strengths are selected for filling.
[0009] In addition, since the portion where the head support portion 10 and the support portion 20 meet forms a predetermined radius of curvature, even if the head turns left or right when lying down, the face can be prevented from sinking too deeply, and severe bending can be prevented from occurring at the junction where the head support portion 10 and the support portion 20 meet when the head is squeezed due to the weight of the head. In terms of appearance, the aesthetics can also be improved by designing a gentle curve and a sense of volume.
[0010] On the other hand, when lying down directly with the pillow 1 turned over and the upper end 22 of the support part 20 located on the ground, since the protruding height of the upper end is 2 cm to 3 cm, the height from the ground to the lower surface 14 of the head support part 10 is 8 cm to 9 cm, and when the head support part 10 and the support part 20 are squeezed to a degree of 3 cm due to the weight of the head, the total height from the ground to the head is reduced to about 5 cm to 6 cm, which is suitable for sleeping.
[0011] On the other hand, the height described above varies depending on the age, gender or physical characteristics of the user and cannot be standardized, but the thickness and amount of the filler need to be adjusted to form a height that suits the user's own body shape.

[0087] according to Figures 1 to 6 The first embodiment is described in detail as follows.
[0088] First, a description of the terminology is as follows.
[0089] The head placement portion a may be the same portion as the connection portion 210 of the C-shaped pillow 200 .
[0090] The cervical vertebra placement part b refers to the term for the central part of the straight-shaped pillow 100 formed by connecting the straight-shaped pillow 100 and the connecting part 210 of the C-shaped pillow 200 .
[0091] The face placement portion c is a term generally referring to a portion where the wings 220 and 230 of the C-shaped pillow 200 and the thickness of the straight-shaped pillow 100 are combined with each other.
[0092] The above-mentioned definitions of terms are applicable to the case where the central portion of the straight-line pillow 100 is configured as the cervical vertebra placement portion b.
[0093] On the contrary, the connection portion 210 of the C-shaped pillow 200 may also be configured as a cervical vertebra placement portion b.
[0094] If configured in this manner, the center portion of the I-shaped pillow 100 will be configured as the head placement portion a.
[0095] The face placement portion c is as described above.
[0096] x is the thickness of the head placement part, y is the thickness of the cervical placement part, and z is the thickness of the face placement part.
[0097] The large volume and small volume described in the specification are used in the same meaning as the large thickness and small thickness.
[0098] Pillows are generally made of cloth, so the larger the volume, the thicker it will naturally be.
[0099] The detailed description is as follows with reference to the accompanying drawings.
[0100] A C-shaped pillow 200 is formed.
[0101] The straight-line pillow 100 is configured to overlap the C-shaped pillow 200 and be attached to the C-shaped pillow 200 in a straight line, and the C-shaped pillow 200 is configured to include wing portions 220 and 230 and a connection portion 210 .
[0102] The wing portion is composed of a first wing portion 220 and a second wing portion 230 .
[0103] The straight-line pillow 100 is formed by connecting or overlapping the connecting portion 210 connecting the first wing 220 and the second wing 230, and the thickness of the face placement portion c as the side portion of the pillow and the central portion of the pillow are different from each other.
[0104] Additionally, the central portion of the pillow is also configured to have a difference in thickness between the front and rear, and the cervical vertebra placement portion b and the head placement portion a are configured to have different thicknesses from each other.
[0105] That is, the thickness of the cervical vertebra placement portion b is configured to be thicker than the thickness of the head placement portion a.
[0106] Therefore, the unequal thickness pillow is used to protect the cervical spine and provide a good sleep regardless of the user's posture.
[0107] The cervical vertebra placement portion b and the connecting portion 210 have different thicknesses to protect the cervical vertebra.
[0108] That is, the cervical vertebra placement part b as a part contacted by the cervical vertebra has a thickness greater than the head placement part a, so that the cervical vertebra of the user using the pillow is in an inverted C shape, thereby treating the cervical vertebra or protecting the cervical vertebra by placing the cervical vertebra.
[0109] On the contrary, the connection part 210 may be configured as the cervical vertebra placement part b and the cervical vertebra placement part may be configured as the head placement part a. That is, the connection part may be configured to be thicker.
[0110] People who use the pillow can naturally turn their heads and lie down even if they turn their bodies to one side while sleeping.
[0111] That is, even when the head is moved sideways, the tilt angle can be made gentle, so that the head can move naturally.
[0112] Depending on the user's intent, Figure 1 The situation of pillow in the state of Figure 5 The situation of the pillow in the state of pillow.
[0113] When Figure 5 When using the pillow in a situation where the user naturally turns the body to sleep on the side, the head will move more naturally to the side direction of the pillow, allowing for a full sleep.
[0114] Of course, even with Figure 1 When using a pillow, the face placement part can naturally form an inclination angle from the cervical placement part, so that it is natural that the head can naturally move to the side.
[0115] In addition, in the case where the hand is put between the face and the pillow when sleeping on the side, since the cross-section of the pillow on both sides is higher than the height of the face placement part, it has the effect of preventing the habit of putting the hand between the face and the pillow when sleeping.
[0116] The above-mentioned effects are commonly applicable to all the embodiments.
[0117] The thickness of the side portion of the pillow (i.e., the thickness of the face placement portion c) is made thicker than the thickness of the pillow when the user lies on the pillow frontally, so that the thickness of the face placement portion c is made to have a sufficient thickness, so that the cervical vertebra can be located in the same straight line as the spine even when lying on the side, and the cervical vertebra will not bend on the face placement portion c of the pillow.
[0118] The pillow includes: a cervical vertebra placement part b, which contacts the user's cervical vertebra; a head placement part a, which contacts the back of the user's head; and a face placement part c, which contacts the face when the user changes his posture to the side.
[0119] The pillow is constructed in such a way that the thickness of the head placing part a, the cervical vertebra placing part b and the face placing part c gradually becomes thicker in this order. When the user sleeps upright, the cervical vertebra placing part b is thicker than the head placing part a, so that the cervical vertebra of the user placed on the cervical vertebra placing part b can maintain an inverted C shape.
[0120] In addition, even when the user sleeps on his side, the wing becomes naturally thicker toward the side of the pillow, so that the user's head naturally moves toward the side of the pillow. The wings 220 and 230 of the I-shaped pillow 100 and the C-shaped pillow 200 overlap on the side of the pillow, creating a height difference between the shoulders and the face, thereby freeing the shoulders from burden. That is, the distance from the ground to the face placement part c can be the same as or greater than the distance from the shoulders to the face, thereby ensuring a good sleep.
[0121] The distance from the shoulder to the face refers to the thickness when the pillow is lying down with the side of the face resting on the face placement part c of the pillow.
[0122] The entire structure of the pillow may be formed into an integrated structure instead of combining the I-shaped pillow 100 and the C-shaped pillow 200 .
[0123] The pillow core can also be a soft type, but it is also okay to use a pillow core with a certain degree of elastic strength such as memory foam.
[0124] The utility model aims to gradually increase the distance from the floor to the head, the distance from the floor to the cervical vertebra, and the distance from the floor to the side of the face, thereby protecting the cervical vertebra, improving the sleep quality and ensuring a good sleep.
[0125] according to Figures 7 to 11 The second embodiment is described in detail as follows.
[0126] A C-shaped pillow 200 is formed.
[0127] The I-shaped pillow is attached to the C-shaped pillow 200 along the length direction and overlapped with the C-shaped pillow 200 .
[0128] The C-shaped pillow 200 is composed of wing portions 220 , 230 and a connecting portion 210 .
[0129] The wing portion is a portion of the C-shaped pillow 200 that is bent up and down, and the connecting portion 210 refers to a central portion of the C-shaped pillow 200 .
[0130] The straight-line pillow is constructed in such a way that a volume portion 110 of one side surface along the length direction is larger than a volume portion 120 of the other side surface.
[0131] The central portion of the one-side volume portion 110 constitutes a cervical vertebra placement portion b.
[0132] The central portion of the other side volume portion 120 constitutes a head placement portion a.
[0133] The wing portion and the left and right side portions of the lateral volume portion 110 separated from the central portion are formed by overlapping a C-shaped wing portion 200 and a straight-line pillow, thereby forming the thickest portion.
[0134] The left and right sides of the pillow are configured as a face placement portion c, and the head placement portion a, the cervical placement portion b and the face placement portion c have different thicknesses respectively, and are configured in a manner in which the thickness gradually becomes thicker, so the unequal thickness pillow is configured to ensure a good sleep regardless of the user's posture.
[0135] according to Figures 12 to 15 The third embodiment is described in detail as follows.
[0136] The first C-shaped pillow 200 has the same structure as the C-shaped pillow 200 in the first embodiment.
[0137] The second C-shaped pillow 300 overlaps with the first C-shaped pillow 200 and is attached to the first C-shaped pillow 200 .
[0138] The first C-shaped pillow 200 and the second C-shaped pillow 300 are both composed of wing parts and connecting parts 210 and 310 .
[0139] The first C-shaped pillow 200 and the second C-shaped pillow 300 are attached and configured to overlap in opposite directions.
[0140] The first C-shaped pillow 200 is configured to be smaller in volume than the second C-shaped pillow 300 .
[0141] The first connecting portion 210 of the first C-shaped pillow 200 with a smaller volume constitutes a head placement portion a.
[0142] The second connection portion of the second C-shaped pillow with a larger volume constitutes the cervical vertebra placement portion b.
[0143] The wing parts of the first C-shaped pillow 200 and the second C-shaped pillow 300 are overlapped to form a face placement part c.
[0144] The head placement part a, the cervical vertebra placement part b and the face placement part c have different thicknesses respectively and are configured in a manner of gradually increasing thickness, so that the unequal thickness pillow is configured to ensure a good sleep regardless of the user's posture.
[0145] according to Figures 16 to 21 The fourth embodiment is described in detail as follows.
[0146] Form a straight-line pillow.
[0147] The one side volume portion 110 is configured to be larger than the other side volume portion 120 in the longitudinal direction of the straight-shaped pillow.
[0148] The central portion of the larger side volume portion 110 constitutes a cervical vertebra placement portion b.
[0149] The central portion of the other side volume portion 120 having a smaller volume constitutes the head placement portion a.
[0150] The left and right sides of the straight-line pillow are attached with support parts 130 having the same straight-line volume in the horizontal direction.
[0151] The left and right sides of the I-shaped pillow constitute a face placement portion c, and the head placement portion a, the cervical placement portion b and the face placement portion c have different thicknesses respectively, and are constructed in a manner in which the thickness gradually becomes thicker, so the unequal thickness pillow is constructed to ensure a good sleep regardless of the user's posture.
