Description

  The present invention relates to a sleeping pillow that allows a comfortable sleep and deep sleep.

  There are various types of sleeping pillows on the market, but many people are not satisfied with the sleeping pillows they use, have trouble sleeping, cannot sleep well, and their neck and shoulders hurt when they get up Have dissatisfaction.

  Conventionally, sleeping pillows have been required to be able to sleep well, and have a cushioning property including hardness, for example, a large amount of granular solid material such as breathable buckwheat husk and synthetic resin beads in the bag Many filled ones are used.

  In addition, since emphasis is placed on shape retention, some materials such as urethane are covered with a cover. In this case, although there is a cushioning property, the air permeability is poor. Alternatively, ceramic pillows may be used for breathability.

  However, any of the conventional sleeping pillows has advantages and disadvantages, and there are few that have all of cushioning properties, breathability, and shape retention properties. Even if buckwheat husks or beads are used, they are filled with a large amount of solid material, and the air permeability is not necessarily good, and there is a problem that the shape is easily lost during sleep. In addition, pillows using molding materials have poor air permeability, and ceramic sleeping pillows have good air permeability but are too heavy and hard to feel.

  For example, the pillow of Patent Document 1 has cushioning properties and is not easily deformed. However, it cannot be said that the air permeability is sufficient, and the plate-like synthetic resin material directly contacts the head, and the touch feeling is not good.

  The object of the present invention is to eliminate the above-mentioned problems, and by interposing a shape-retaining member between synthetic resin substrate materials having a large number of ventilation holes, it is difficult to lose shape, and cushioning properties and air permeability are improved. An object of the present invention is to provide a sleeping pillow that is good and that has a lot of flexible protruding strips on the surface, so that the touch to the head is good.

  In order to achieve the above object, a sleeping pillow according to the present invention is a sheet-like pillow made of a synthetic resin material provided with a large number of vent holes and a large number of flexible and elastic protrusions on the surface. A substrate material is provided, the substrate material is rounded into a substantially elliptic cylinder shape, and a shape-retaining member is provided which has air permeability between the upper and lower substrate materials and retains the shape between the substrate materials. .

  The pillow for sleep according to the present invention is less likely to lose its shape, has good cushioning properties and breathability, and can sleep well and sleep well.

It is a perspective view of the substrate material back surface of Example 2. FIG. It is a side view. 6 is a side view of Example 3. FIG. 10 is a side view of Example 4. FIG. It is a perspective view of a frame.

  The present invention will be described in detail based on the embodiments shown in the drawings.

  FIG. 1 is a perspective view showing a state in which a part of a cover of a sleeping pillow 1 according to the present embodiment is cut out. A sheet-like substrate material 2 made of a synthetic resin material having elasticity is curved and is substantially curved. By rounding into an elliptical shape, for example, a substantially oval cross-sectional shape or a substantially cross-sectional peanut shape with a recessed central portion is obtained. A cover 3 is attached around the substrate material 2. In terms of dimensions, for example, the length is 80 cm, and the width is 23 cm including the length of the protruding strip described later, and the thickness is 8 cm.

  2 is a perspective view of the surface of the substrate material 2, FIG. 3 is a perspective view of the back surface, FIG. 4 is an enlarged perspective view of the surface of the substrate material 2, and FIG. 5 is an enlarged perspective view of the back surface. The substrate material 2 is, for example, a rectangle having a size of 60 cm × 80 cm, and a plurality of square frame-shaped frame members 4 each having a vent hole 4a are connected in the side direction in order to provide air permeability, light weight, and elasticity. In this manner, a cross beam 4b for reinforcement is formed in the frame member 4 so as to connect the corner portions. In the drawing, the frame member 4 and the cross beam 4b are omitted for the sake of illustration.

  On the surface of the frame member 4, a large number of elastic protrusions 5 are planted at a high density in the direction perpendicular to the surface of the frame member 4. The ridge piece 5 has elasticity, and the tip portion 5a is frequently bent laterally in order to reduce irritation by the tip portion 5a of the ridge piece 5 and increase cushioning properties. In addition, on the back surface of the substrate material 2, a large number of short columns 6 are integrally molded as a shape-retaining member.

  The protruding strip 5 is formed in a strip shape having a width of about 1 to 2 mm, a thickness of about 0.5 mm, and a length of about 12 mm, for example, and is often thick at the base of the frame member 4, as it goes to the tip 5 a. It is getting thinner. Moreover, the bending direction of the front-end | tip part 5a is not a fixed direction, but has faced the opposite direction in the random direction or adjacent protrusion pieces 5 mutually. By planting such protruding strips 5 at a high density, for example, it becomes a property like an artificial turf, and the substrate material 2 can be given appropriate cushioning properties and flexibility.

  As shown in FIG. 6, the sleeper pillow 1 is formed while rolling both sides of the substrate material 2. In the process, a separate intermediate plate 7 is arranged between the upper and lower substrate materials 2 as shown in FIG. 7. To do. On the upper and lower surfaces of the intermediate plate 7, a large number of short cylindrical receiving portions 7 a into which the front end portions 6 a of the columns 6 are fitted are molded. By fitting the front end portion 6a of the column 6 to the receiving portion 7a of the intermediate plate 7, the substrate material 2 is held in a pillow shape.

  In addition, the length of the support | pillar 6 can be designed suitably with the shape and size of the pillow 1 for sleep, For example, length is set to about 3-5 cm. By making the length of the support column 6 shorter in the central part than the parts on both sides, the sleeping pillow 1 having a cross-sectional peanut shape in which the height of the central part is recessed can be obtained.

  As described above, the sleeping pillow 1 of the first embodiment can shorten the length of the support 6 by arranging the intermediate plate 7 in the intermediate portion between the upper and lower substrate members 2 of the sleeping pillow 1. The shape is stable. Then, by giving the support 6 elasticity, the sleeping pillow 1 can also be cushioned by the support 6.

  In the first embodiment, the support column 6 is fitted and connected using the receiving portion 7a of the intermediate plate 7. However, without using the receiving portion 7a, the tip end portion 6a of the support column 6 is shaped like a flat plate, You may provide the contact part for abutting the front-end | tip part 6a of the support | pillar 6 with the board 7. FIG.

  Furthermore, when the board | substrate material 2 is curved and it is set as the pillow 1 for sleep, it is necessary to join the matching parts of the board | substrate material 2 in the lower surface, For example, a collar part, a fitting part, or a joining member which is not shown in figure is used. Since the sleeping pillow 1 may be used with the front and back reversed, it is preferable that no stepped portion is formed at the joint portion.

  Thus, when the board | substrate material 2 is curved and the support | pillar 6 is latched to the intermediate | middle board 7, if the mating part of the board | substrate material 2 is joined, the original pattern of the pillow 1 for sleep will be formed. It is preferable to use a cloth cover 3 made of air-permeable cloth that is sewn around the sleeping pillow 1 in order to reduce irritation of the tip 5a of the protrusion 5 and absorb sweat. It is.

  Since the sleeping pillow 1 of the first embodiment does not require the use of a filler as in the conventional pillow, it does not store heat, is not easily deformed, and has good shape retention. Moreover, the cushioning property by the ridge piece 5 and the touch feeling are good, the cushioning property by the board | substrate material 2 and the support | pillar 6 is excellent, the air permeability between the ridge pieces 5, and the air permeability between the front and back of the board | substrate material 2 are excellent. So you can sleep well and sleep well.

  FIG. 8 is a perspective view of the back surface of the substrate material 2 according to the second embodiment. On the frame member 4 on the upper back surface of the substrate material 2, for example, a large number of pillars 11 having a diameter of 3 mm and a length of 6 cm are shaped. The members are erected at a predetermined pitch. When the substrate material 2 is rolled up into a pillow shape, the support column 11 retains its shape and obtains cushioning properties, and is used to provide air permeability between the substrate materials 2.

  On the frame member 4 on the back surface on the lower side of the substrate material 2, when the substrate material 2 is curved, a short cylindrical receiving portion 12 that fits with the tip end portion 11 a of the column 11 is formed at the same pitch as the column 11. Is provided.

  The side view of FIG. 9 shows a state in which the column 11 is fitted to the receiving portion 12. The substrate member 2 composed of the frame member 4, the protruding strip 5, the support column 11, and the receiving portion 12 is integrally formed by injection molding.

  In the second embodiment, the support column 11 is connected by the receiving portion 12, but the tip end portion 11 a of the support column 11 may be a large-diameter cylindrical portion that is fitted to the receiving portion 12 from the outside. Moreover, it is good also as a contact part which contact | abuts the front-end | tip part 11a with the back surface of the board | substrate material 2 instead of the receiving part 12. FIG.

  In the first and second embodiments, the support columns 6 and 11 are formed integrally with the frame member 4. However, in the third embodiment, a connecting member having elasticity that is separate from the substrate material 2 is used as a shape-retaining member. The substrate materials 2 are connected to each other. As shown in FIG. 10, many short cylindrical receiving portions 21 are provided on the frame member 4 of the substrate material 2 on the back surfaces of the upper and lower substrate materials 2.

  The shape of the sleeping pillow 1 is maintained by curving the substrate material 2 and fitting both ends of a rod-shaped connecting member 22 made of, for example, a synthetic resin material into the receiving portions 21 of the upper and lower substrate materials 2.

  Moreover, it can be set as the pillow 1 for sleep which has favorite cushioning properties by changing the number of this connection member 22, a diameter, and a material.

  Although the rod-like connecting member 22 is used in the second embodiment, a hollow cylindrical member may be used as the connecting member 22 and both ends of the cylindrical member may be fitted to the outside of the receiving portion 21.

  FIG. 11 is a side view of the fourth embodiment, and functions as a shape-retaining member between the upper and lower substrate members 2, and a frame 31 separate from the substrate member 2 is inserted as shown in FIG. Yes. This frame 31 has beams 31a corresponding to the corners of the rectangular parallelepiped, and is provided with reinforcing beams 31b for reinforcing the space between these beams 31a. And it is preferable that this frame 31 has moderate elasticity in the up-down direction by giving cushioning to the sleeping pillow 1.

  The frame 31 is not necessarily a rectangular parallelepiped, and the beam 31a may be formed by a curve in order to round the shape of the sleeping pillow 1.

  In addition, although the sleep pillow 1 of Examples 1-4 was manufactured by curving one board | substrate material 2, it does not necessarily need to be one piece and it produces it by connecting the several board | substrate material 2. FIG. May be.
