Description

  The present invention relates to a pillow that can provide an optimal sleeping posture by supporting a user's cervical vertebra during sleeping.

  Originally sleeping in the wrong posture is said to cause stiff shoulders, neck pain, other physical illnesses or snoring. This is because, without using a pillow suitable for the user, a position such as the height of the cervical vertebra in the sleeping posture erroneously places a burden on the cervical vertebra. Therefore, it is preferable that the posture at the time of sleeping does not apply a burden to the cervical vertebra. In the meantime, conventionally, pillows that support the cervical vertebra are provided with attention paid to the length of the cervical vertebra and the depth of curvature of the cervical vertebra.

  For example, the height of the cervical vertebra pack can be adjusted by placing the sheet material under the cervical vertebra pack that is placed on the body side of the head pack and supports the cervical vertebra, and the user can easily adjust the height. Therefore, a cervical spine support / height adjustment pillow capable of obtaining a comfortable sleeping state is provided (Patent Document 1).

  On the other hand, it is provided at a position corresponding to the human head and is equipped with a storage part that can select and store the type of cushioning material or the amount of cushioning material. A pillow capable of adjusting the height of the shoulder is also provided (Patent Document 2).

Utility Model Registration No. 3137305 JP2013-116295A

  However, in the pillow described in Patent Document 1, the cervical vertebrae can be supported by the cervical vertebra pack at bedtime, but the adjustment by overlapping the sheet material is ambiguous and conforms to the undulating shape near the individual cervical vertebrae of each user. Although it cannot be supported, and the user can adjust the height to the user's preferred height by stacking the sheet material, the height is not necessarily supported by the user's individual cervical spine The height of the cervical vertebra pack is not limited to the optimal height for the cervical vertebrae, because the cervical vertebra pack is formed by filling a cloth bag with fillers such as spherical cotton, buckwheat and cotton used for ordinary pillows. When the user's head moves during support, it bends, for example, when the user turns from the back to the side, it sinks along the shape that supports the side of the neck, so the cervical vertebra cannot be supported properly, and the cervical vertebra is optimal Can't maintain good support There has been a problem to say.

  Moreover, although the technique of patent document 2 can adjust the height of the head in the pillow at the time of sleeping, and the height of a shoulder, there existed a problem that the cervical vertebra part could not be supported in the first place.

  Accordingly, the present invention provides a pillow that can maintain an optimal sleeping posture for each user by supporting the cervical vertebra portion along the undulating shape near the individual cervical vertebra portion and the height from the bed surface. It was an issue to provide.

In order to solve the above problems, the present invention is configured as follows.

  Hereinafter, the present invention will be specifically described with reference to the drawings. First, FIG. 1 is a perspective view showing a pillow 1 according to the present invention. The pillow 1 is composed of a pillow body 2 and a cervical vertebra support 3, and a pillow cover 4 is attached to the pillow if necessary. 1 is coated.

  The pillow body 2 is formed in a substantially square shape with an opening 2a provided on the upper surface. The substantially square-shaped pillow body 2 includes spherical cotton, buckwheat, cotton and the like used for ordinary pillows. The filling material is filled in the cloth bag. The opening 2 a is formed to penetrate from the upper surface to the lower surface of the pillow body 2, and when the cervical vertebra support 3 is fitted, the lower surface of the cervical vertebra support 3 passes through the pillow cover 4. It is formed in contact with the bed surface. Note that the opening 2a is not limited to penetrate from the upper surface to the lower surface of the pillow body 2, and it is sufficient that the opening 2a can form at least a depressed portion into which the cervical vertebra support 3 can be fitted.

  Further, the opening 2a of the pillow body 2 is formed closer to the user's body side than the center in the lateral direction in the substantially square-shaped pillow body 2. Accordingly, when the user places the head on the pillow, the head of the user can be sufficiently protected on the head side of the pillow body 2, and the cervical support by the cervical support Protection of the head with the pillow body can be provided in an appropriate balance, and more comfortable sleep can be provided to the user.

  FIG. 2 is a perspective view showing the cervical vertebra support 3. The cervical vertebra support 3 is a substantially rectangular parallelepiped of an elastic body such as a synthetic resin, and is used as shown in the AA sectional view of FIG. 3A and the BB sectional view of FIG. The undulation shape in the vicinity of the individual cervical vertebra is measured, and the upper surface of the elastic body is formed as the cervical vertebra contact surface 3a according to the measured value. The cervical vertebra contact surface a can fit and fit with the user's cervical vertebra at the time of sleeping. Then, the substantially square-shaped pillow body 2 supports the back of the head and shoulders except for the user's cervical vertebrae, and provides a comfortable fit for the user's head and shoulders. Can be provided.

  On the other hand, the lower surface of the cervical vertebra support 3 is formed in a plane that contacts the bed surface via the pillow cover 4 as shown in FIGS. 3 (a) and 3 (b). The cervical vertebra support 3 is formed so as to be stable when the pillow 1 is placed on the bed surface so that the cervical vertebra contact 3a is appropriately supported. In addition, the lower surface of the cervical vertebra support 3 may be formed in a convex shape having a front view arc shape substantially parallel to the upper surface. The cervical vertebra support 3 swings to the left and right by making the lower surface a curved surface with an arc of front view, and does not overly fix the sleeping posture. You can go to bed without feeling inconvenient.

  Further, the cervical vertebra support 3 is formed at an optimum height for each user according to the height from the individual bed surface to the vicinity of the cervical vertebra when the pillow 1 is installed on the bed surface. In addition, the cervical vertebra contact portion 3a of the cervical vertebra support 3 is formed with a height that is exposed from the upper surface of the pillow body 2. The height of the cervical vertebra support 3 is too high or too low for each user, and places a burden on the user's shoulder and neck muscles. It will be formed.

  Although not shown, the cervical vertebra support 3 measures the undulation shape near the cervical vertebra for an unspecified number of users, and forms the cervical vertebra support 3 along the average of the measured values. Alternatively, a ridge is provided in the center by providing a recess on the head side and body side of the cervical vertebra contact surface 3a, and the ridge is formed so as to support the user's cervical vertebra. It is also possible to form a general-purpose cervical vertebra support 3 even if the cervical vertebra support 3 having an optimum shape for each user is not formed.

  The cervical vertebra support 3 is formed of an elastic body such as a synthetic resin such as urethane resin or ABS resin, or a foamed resin such as urethane foam. The elastic force of the cervical vertebra support part 3 may be changed according to the individual preference of the user, and if the user prefers to support the cervical vertebra with a firm and firm shape, the elastic body formed to be hard On the other hand, if the user prefers to obtain a soft and fit to the cervical vertebra, the cervical vertebra support 3 may be formed using a soft elastic body. The cervical vertebra support 3 is not limited to an elastic body made of synthetic resin, and may be anything as long as it has a hardness to support the cervical vertebra. For example, it may be a cervical vertebra support 3 made of wood or metal, may be a cervical vertebra support 3 formed by wrapping a cloth around the wooden or metal core, and the cloth is rolled. The cervical vertebra support 3 made of cloth may be used, or the cervical vertebra support 3 formed by combining these may be used.

  In the formation of the cervical vertebra support 3, a method for measuring the undulation shape in the vicinity of the individual cervical vertebra and the height to the bed surface is not particularly shown. Each distance to the vicinity of the head is measured, and the cervical vertebra support 3 is formed while forming a curved surface on the cervical vertebra contact surface 3a at a height corresponding to the measured value, or from the back of the user in the sleeping position The shape up to the shoulder through the cervical vertebra may be modeled, and the cervical vertebra support 3 may be formed according to the modeled shape. The measurement method is not limited to a specific method, and it is possible to measure the undulation shape near the cervical vertebrae of each user and the height to the bed surface. Any method may be used as long as the cervical vertebra support 3 having a shape and height capable of taking a proper posture can be formed.

  The pillow cover 4 covers the pillow body 2 and the cervical vertebra support 3, and is not particularly limited, and may be a bag such as a cloth cover that is generally used everyday. Any material may be used as long as the pillow body 2 and the cervical vertebra support 3 are covered with a stain to prevent contamination and appearance decoration.

  FIG. 4 is a cross-sectional view showing the use state of the pillow 1. As shown in FIG. 4, when sleeping using the pillow 1, the cervical vertebrae of the user contacts the cervical vertebra contact surface 3 a of the pillow 1, and the cervical vertebrae near the individual cervical vertebrae are formed along the contoured shape In addition, the cervical vertebrae support 3 formed according to the height of the individual cervical vertebrae from the bed surface of the user supports the cervical vertebrae of the user in an optimal posture, which is caused by an incorrect posture at bedtime. It can prevent stiff shoulders, neck pain, other physical diseases or snoring. Further, the user's head and shoulders are respectively placed on the head side and body side of the pillow body 2 of the pillow 1 and are supported by the cervical vertebra support 3 due to the cushioning property of the pillow body 2. There is no burden due to the difference in height from the cervical spine. Therefore, by using the pillow 1, the user can sleep comfortably without feeling any burden.

  The manufacturing method of this pillow 1 is demonstrated below. First, the undulation shape in the vicinity of each user's cervical vertebra and the height from the cervical vertebra to the bed surface are measured. As described above, the measurement method is not particularly limited, as long as the undulating shape and the height from the bed surface to the vicinity of the cervical vertebra near the individual cervical vertebra can be measured by a predetermined measurement method.

  Next, on the basis of the measurement value obtained by the measurement method, the upper surface of the elastic body made of synthetic resin or the like is cut out along the undulation shape in the vicinity of the individual cervical vertebrae, and the upper surface is the cervical vertebra contact surface The cervical vertebra support 3 conforming to the contoured shape near the cervical vertebra of each user is formed as 3a. Further, the height of the cervical vertebra support 3 is adjusted according to the height from the vicinity of the user's cervical vertebra to the bed surface obtained by the measurement. Further, the bottom surface of the cervical vertebra support 3 is formed to be flat and stable with respect to the bed surface.

  Next, the pillow body 2 having a substantially square shape and having an opening 2a on the surface is formed. The substantially square-shaped pillow body 2 is formed by filling a cloth bag with a filler such as a spherical cotton, buckwheat glass or cotton used for a normal pillow. The opening 2a is formed so as to penetrate from the upper surface to the lower surface of the pillow body 2. Further, the opening 2 a is formed closer to the body side than the center of the pillow body 2 in the short direction.

  Then, the cervical vertebra support 3 is fitted into the opening 2a so that the cervical vertebra contact surface 3a is exposed upward. Therefore, the opening 2a can be fitted to the cervical vertebra support 3 and the length and width of the cervical vertebra support 3 can be prevented from being displaced in the opening 2a. Formed with suitable size.

  As a result, the pillow 1 along the undulation shape near the cervical vertebrae of each user and the height to the bed surface can be made to order, and the posture at the time of sleeping is optimally adapted to each user. It does not place a burden on the cervical vertebra, and can prevent stiff shoulders, neck pain, other physical illnesses or snoring due to an incorrect posture at bedtime. Note that when the pillow 1 is used, the pillow cover 4 can be covered with the pillow 1 as necessary to prevent the pillow 1 from being soiled or decorated.

  Next, the cervical vertebra support 3 according to the pillow 1 of the second embodiment will be described with reference to FIGS. 5 and 6. Since the pillow body 2 has the same configuration as that of the above embodiment, the description thereof is omitted here. FIG. 5 is a perspective view showing a configuration of the cervical vertebra support 3 according to the pillow 1, and FIG. 6 is a perspective view showing a use state of the pillow 1.

  As shown in FIG. 5, the cervical vertebra support 3 has a hardness capable of supporting an elastic body made of a synthetic resin or the like or the cervical vertebra as in the cervical vertebra support 3 of the embodiment. A cervical vertebra contact surface 3 a that is made of a substance having a contact with the cervical vertebrae of the user in a sleeping posture is formed at the center of the upper surface of the cervical vertebra support 3. In addition, the left and right sides of the cervical vertebra support 3 extending from the center to the left and right are either left or right of the user as the user's head rotates when turning over to the left and right upper surfaces. Ear mounting portions 3b and 3b on which such ears are placed are provided. The ear placement portions 3b and 3b are formed with holes of a size that can accommodate the ears of the user's head rotated by turning over. Thereby, since a user's ear fits in this ear mounting part 3b, 3b, when he turns over, the user can sleep comfortably without squeezing the ear and feeling uncomfortable. The ear placement portion 3b is not limited to providing a hole, but may simply prevent the ear from being uncomfortable due to the cushioning property of the elastic body extending left and right from the center of the cervical vertebra support 3. Good.

  FIG. 6 is a view seen from the top of the head showing the usage state of the pillow 1. The user's head rotates as the user rolls over, and at that time, the user's ears are fitted into the ear placement portions 3b and 3b and pressed so as to prevent the user's sleep. Rather, the user can sleep comfortably while turning over. Thus, by providing the ear placement portion, it is possible to turn over comfortably without squeezing the ear, and even after turning over, the cervical vertebra portion does not fall off from the cervical support 3. The posture can be easily returned to the central cervical vertebra contact surface 3a.

  If not only a pillow but also a massage chair, a cushion or the like that is used in contact with the head for a long time, the cervical spine support 3 of the pillow 1 can be used as an optimum for each user. it can.
