Description

  The present invention relates to a pillow that supports the neck and the head.

  In recent years, a variety of pillows that are comfortable to support according to the shape of the head and neck have been developed.

  Many pillows that consist almost entirely of low-resilience urethane foam and that support the shape of the head and neck mainly due to the low resilience of the material have been developed and are commercially available. Also, the bag body is filled with buckwheat, beads, pipes, etc. The pillow is supported mainly by the flow of the material according to the shape of the head and neck, etc./The pillow body is packed with the pillow material, and a concave depression is formed in the center of the pillow. Pillows that are formed and supported according to the shape of the head and neck, etc./ Also, pillows that are comprised of multiple inner bags and compartments filled with pillow materials and supported according to the shape of the head and neck, etc. Many have been developed and are commercially available.

  However, the shape of the head and neck, etc., vary widely, and there are large individual differences, making it difficult to produce pillows corresponding to this, and when actually using a pillow, the shape and hardness of the pillow that supports the head and neck Etc. often do not suit the user. For this reason, the pressure (reaction force) at the head and neck muscles cannot be dispersed well, and the pressure (reaction force) tends to be partially increased particularly at the head. For this reason, pressure is easily generated in the portion, and the blood flow tends to decrease. Moreover, in the neck part, if it deform | transforms along a neck part shape and does not support softly, pressure (reaction force) will become strong, and there exists a danger of the fall of a blood flow and the nerve being compressed. However, it is difficult to softly support the neck, so the neck tends to be under-supported and muscle tension tends to occur in the neck.

  As mentioned above, if pressure is applied to the head and blood flow is reduced, or muscle tension is generated in the neck, it takes time to fall asleep, many times you wake up, and sleep is shallow. Will be damaged.

  With pillows that are almost entirely made of low-resilience urethane foam, the head has a low resilience characteristic, and even if it seems that pressure (reaction force) is distributed from the head to the neck, The resilience elastic force, hardness, and the like do not always match the shape of the neck and neck, and for example, the pressure (reaction force) partially increases in a portion where the amount of compressive displacement is large.

  Pillows filled with buckwheat, beads, pipes, etc. in the bag body have the advantage of easily dispersing pressure (reaction force) due to the flow of the material, but are likely to lose shape and change the pillow height during use. , It will not fit the shape of the head and neck.

  Pillows filled with pillow material in the body, pillows with a concave recess in the center of the pillow, pillows made up of multiple inner bags or compartments filled with pillow materials inside the pillow, etc. have a shape and height that supports the head and neck However, it is not possible to cope with this because there are large individual differences in the shape of the head and neck.

Therefore, in the pillow handling industry, comfortable pillows are developed that can cope with individual differences such as the shape of the head and neck muscles and are less likely to cause muscle tension in the neck muscles and pressure or blood flow in the head. Looking forward to.

In use, the height of the head is set to be about 30 mm to 40 mm. Further, both sides of the head placement part m1 are set to be slightly higher than the center part of the head placement part m1 corresponding to the lying posture due to turning over or the like. This pillow M is a rather low pillow, but the height can be arbitrarily set depending on the design.

  As shown in FIG. 3, the core body 1 is made of a cloth composed of a bag body 10 and a mouth portion 11 for taking in and out the small solid material 5 into and from the bag body 10 (polyester or mixed spinning, etc.). The mouth portion 11 can be opened and closed by a fastener 12 so that the amount of the small solid 5 can be increased or decreased. As shown in FIG. 3, the size of the core body 1 in plan view is the size of the portion in which the bag body 10 is filled with the small solid material 5 and is about 280 mm long × 520 mm wide. In the width and length directions that support the head in response to turning over, the head has a length that is supported from the head to the neck.

  Further, the core body 1 has flow resistance means 4 for controlling the flow of the small solid material 5, and the upper and lower surfaces of the bag body 10 as shown in FIG. 2 and FIG. It is comprised by the gusset cloth provided between. The gusset cloth is sewn and attached to the fabric on the upper surface and the fabric on the lower surface immediately below, and by changing the length of the gusset fabric between the upper surface and the lower surface (hereinafter referred to as the height of the gusset fabric), 5 is controlled. More specifically, as shown in FIG. 3, gusset cloth a, a, a provided on the back side (the gusset cloth height of about 50 mm to 60 mm) and gusset cloth b, b provided in the center portion. (The height of the gusseted cloth is about 30 mm to 40 mm), the gusseted cloth c, e, e (the height of the gusseted cloth is about 10 mm to 20 mm) provided on the top of the head, and the gusseted cloth d, d / d, d (the height of the gusseted cloth is about 10 mm to 20 mm), and the flow of the small solids 5 is controlled by all the gusseted cloth distributed throughout the bag body 10 described above. In order to achieve this, the flow resistance means 4 is configured. In addition, all the above-mentioned gusset cloth uses what was comprised with the width | variety of about 30 mm-50 mm of a gusset cloth, and polyester or mixed spinning (a thing with small elasticity is desirable). The height of the gusset cloth a, a, a provided on the back side is set higher than the top of the head, so that it can easily follow the shape from the head to the neck when used.

  The base 2 has a size in plan view, a length of about 280 mm × a width of about 520 mm, and is composed of two sheet-like elastic bodies 20 and 21 made of a flexible polyurethane foam, as shown in FIGS. The center part corresponds to the height in the supine posture, and is composed of one sheet-like elastic body 20, and both sides have a width of 15 cm so as to be higher than the center part corresponding to the lying posture. About a sheet-like elastic body 21 is arranged on the sheet-like elastic body 20.

  The sheet-like elastic member 3 has soft elasticity that is easily deformed along its outer shape from the head to the neck, and may be configured as a single layer with, for example, a soft polyurethane foam. Then, as shown in FIG. 1 and FIG. 2, the sheet-like elastic member 3 is configured by a three-layered multilayer structure so as to increase the air permeability as well as the flexibility with respect to the thickness. The outer layer is made of soft polyurethane foam, the middle layer is made of polyester resin cotton, and the inner layer is made of soft polyurethane foam. Further, in this pillow M, as shown in FIG. 2, a space K is somewhat formed between adjacent ones of the outer layer 30, the middle layer 31, and the inner layer 32 on the back side and in the vicinity thereof.

The soft polyurethane foam constituting the base and the sheet-like elastic member 3 has a thickness of about 6 mm to 8 mm and a hardness of about 70 N to 80 N / 314 cm ² . Resin cotton having a thickness of about 5 mm to 10 mm and a weight of about 60 g to 120 g / m ² is employed.

  The inside of the bag body 10 is filled with a small solid material 5. In a state where the user puts the small solid material 5 in and out of the bag body 10 from the mouth portion 11, increases or decreases the amount, adjusts the filling amount, and places the head on the pillow M for use. In addition, at least the upper surface of the bag body 10 is used in an amount that does not bottom the lower surface. The small solid material 5 may be a pipe, sphere, or bead having elasticity, but in this embodiment, a soft cylindrical pipe having a length of about 6 mm and a diameter of about 5 mm (such as polypropylene or Polyethylene) is used to make it flow.

(About the function of this pillow M)
(1) About being able to cope with individual differences such as the shape of the head and hardly causing pressure or blood flow reduction in the head The core body 1 of this pillow M is a bag body to control the flow of small solids 5 10 has flow resistance means 4 (gusset cloth) provided dispersed throughout the interior. As shown in FIG. 5, the flow resistance means 4 has an upper surface of the bag body 10 when the small solid material 5 flows by the gusset cloth provided dispersed throughout the bag body 10. By suppressing the swelling of the lower surface and narrowing the passage through which the small solids 5 flow, the flow resistance is greatly received. By changing the height of the gusset cloth, the magnitude of the flow resistance can be changed, whereby the flow of the small solids 5 can be controlled.

  In this pillow M, the user's head is received on the sheet-like elastic member 3 and supported by the core 1 under the sheet-like elastic member 3 at the head placement portion m1. When the user places the head on the head mounting portion m1, as shown in FIG. 4, the sheet-like elastic member 3 is softly deformed along the head shape and corresponds to the weight of the head. The core body 1 receives pressure from above, and the small solid material 5 inside the bag body 10 is pushed away and flows along the shape of the head to form a recess. However, this pillow M has the flow resistance means 4 (gusset cloth) as described above, and changes the height of the gusset cloth provided dispersed throughout the bag body 10 to change the small solid material 5. When the fluid flows under pressure corresponding to the weight of the head, it is controlled so as to flow the small solid 5 by receiving as much flow resistance as possible. As a result, after the fluid flows, a solid hardness dent corresponding to the weight of the head is formed. Therefore, when the dent is formed in the core body 1, not only is the dent formed along the head shape by the flow of the small solids 5, but also firmly supports this corresponding to the weight of the head. A dimple having a reduced hardness will be formed. Since the bag body 10 is filled with at least the amount of the small solid material 5 whose upper surface does not bottom the lower surface, the depression is always formed in the use state. Since it is supported by the sheet-like elastic member 3 and the core body 1 as described above, the pressure (reaction force) can be dispersed, and the pressure (reaction force) is partially applied to the head received on the sheet-like elastic member 3. The pressure (reaction force) is applied almost evenly without increasing. Therefore, it is difficult to cause pressure in the head and a decrease in blood flow. Even if the position and orientation of the head changes due to turning over, the flow resistance means 4 is provided dispersed throughout the bag body 10 and the flow of the small solids 5 is controlled. Force) is distributed, and the pressure (reaction force) does not partially increase. Moreover, since the volume change of the core 1 is small, there is little shape loss and the head can be supported at a stable height.

Therefore, by using the pillow M of this embodiment, it is possible to cope with individual differences such as the shape of the head, and it is difficult to cause pressure in the head and a decrease in blood flow.
(2) About adapting to individual differences such as the shape of the neck and not causing tension of the neck, the neck is a sheet-like elastic member at the neck placement part m2 of the pillow M as shown in FIG. 3 is received and supported by the core 1 below the sheet-like elastic member 3. The portion of the core body 1 that supports the neck muscle corresponds to the neck muscle by increasing the height of the gusset cloth on the back side of the bag body 10 so that it can easily follow the shape from the head to the neck during use. Further, since the flow resistance does not work strongly by raising the back side gusset cloth, when the neck 1 is supported and pressure is applied to the core body 1, the small solids 5 easily flow along the neck shape. . For this reason, there is little possibility that the pressure (reaction force) applied to the neck muscle becomes large. Further, the sheet-like elastic member 3 for receiving the neck is formed with a space K between the adjacent outer layer 30, middle layer 31, and inner layer 32 on the back side and in the vicinity thereof. Due to the presence of elasticity and space, the sheet-like elastic member 3 can be deformed very softly along the neck shape to receive the neck. Since it is supported by the sheet-like elastic member 3 and the core body 1 described above, there is little risk of causing a decrease in blood flow and nerve compression in the neck, and the neck can be received softly and supported without being under-supported. it can. This makes it difficult to cause muscle tension in the neck.

Therefore, if the pillow M of this embodiment is used, it is possible to cope with individual differences such as the shape of the neck, and it is difficult to cause muscle tension of the neck.
(3) It is possible to cope with individual differences such as the shape of the head and neck, and it is difficult to cause muscle tension of the neck and pressure and blood flow in the head, and it is comfortable to sleep. "It is possible to cope with individual differences such as, and it is difficult to cause pressure in the head and a decrease in blood flow" and "(2) It is possible to deal with individual differences such as the shape of the neck, and it is difficult to cause muscle tension of the neck From the content of "", it is clear that this pillow is comfortable to sleep.
(Other embodiments)
As shown in FIG. 6, the pillow M of Example 1 includes a core body 1 and at least a sheet-like elastic member 3 extending from the upper surface of the core body 1 toward the back side, and the sheet-like elastic member 3. The core 1 is a pillow that is supported by hanging from the head to the neck, and the core body 1 includes the bag body 10 filled with a small solid material 5 in such an amount that the upper surface does not bottom the bottom surface when the head is placed; The flow resistance means 4 may be provided so as to be dispersed throughout the inside of the bag body 10 in order to control the flow of the solid material 5.
