Description

  The present invention relates to a pillow that can be used in general households, particularly to eliminate the difficulty of sleeping in the summer, to make it easier for the user to sleep and to sleep well.

  This type of conventional pillow has a built-in cool storage in the pillow body so that the head can be properly cooled in order to be able to sleep properly without sweating and sticking on the hot summer night. It is intended to cool the pillow user's head through the mat body having the heat transfer plate heat transfer and cushioning action, and cool the cool storage body in a refrigerator or freezer in advance. Some use it to obtain a cool feeling (for example, see Patent Document 1).

  In addition, a net-like net is attached to the upper surface of the pillow frame member so that the air inside the pillow and the air outside the pillow are exchanged through a net having a large number of small holes, and heat is transferred into the pillow. There is one that tries to obtain a cool feeling by keeping the head cool without dampening moisture (see, for example, Patent Document 2).

  However, in the above prior art, the former is troublesome to handle because the regenerator must be taken in and out of the refrigerator or freezer before use. In addition, it is difficult to obtain a comfortable feeling because it is too cold. Moreover, it becomes hard and it is difficult to obtain cushioning properties. Also, the cooling time does not last long. Furthermore, there is a problem that a refreshing feeling cannot be obtained due to high humidity.

  Moreover, since the latter supports the head by a net stretched around the frame, cushioning properties cannot be obtained. In addition, it feels uncomfortable, and even if it rolls over, the net hardly bends, so it is difficult to sleep comfortably, and the warm air in the pillow is not quickly replaced, and the head is not cooled much. There is a problem that it is difficult to get a feeling.

  The present invention has been made to solve the above problems, and in claim 1, a pillow material, a three-dimensional lattice space material placed on top of the pillow material, and a pillow cover made of knit covering the whole of the pillow material, It is composed of

  According to a second aspect of the present invention, the pillow material is made of a material that can form a pillow such as a low resilience polyurethane foam, feathers, cotton, and a pipe made by cutting a plastic straw.

  According to a third aspect of the present invention, a plurality of plastic yarns are knitted so as to maintain an air layer in which the three-dimensional lattice space material communicates.

  According to a fourth aspect of the present invention, the three-dimensional lattice space material is composed of a blend of nylon and polyester or a single material.

  According to a fifth aspect of the present invention, the three-dimensional lattice space material is configured such that the finer side of the lattice is the upper surface and the larger side of the lattice is the lower surface.

  According to the sixth aspect of the present invention, the outer peripheral end of the three-dimensional lattice space material is surrounded by a non-breathable or low-breathable material seal and fixed by sewing.

  The pillow according to the present invention is configured as described above, so that a sufficient space is ensured between the head and the pillow material during sleep, and the pillow material with good cushioning properties, flexibility, flexibility and ventilation are provided. Combined with the three-dimensional lattice space material, it is not too soft, not too hard, moderate hardness and good cushioning, air permeability and heat dissipation, so it is refreshing and cool even at night when it is hard to sleep in summer, Can sleep well.

  Moreover, even if the face is in a landscape orientation and the face comes into contact with the pillow, the skin feels good and the cushioning property is good, so that it is easy to maintain the state as it is, and it becomes useful to prevent snoring by being in the landscape orientation.

  Moreover, even if it becomes sideways, since the finer one of the lattice of the three-dimensional lattice space material is on the upper side, there is no trace of the lattice on the face.

  An embodiment of the present invention will be described below with reference to FIGS. FIG. 1 is a perspective view of a pillow showing an embodiment of the present invention, FIG. 2 is a perspective view showing a partial cross section of the pillow, FIG. 3 is a longitudinal sectional view of the pillow, and FIG. 4B is a bottom view of the three-dimensional lattice space material 4, and FIG. 4C is a side view of the three-dimensional lattice space material 4. FIG.

  In the figure, 1 is a pillow. A pillow material 2 is made of a low-resilience polyurethane foam having a good cushioning property and is housed in a stretchable knit inner bag 3. The inner bag 3 prevents the color of the low resilience polyurethane foam of the pillow material 2 from adhering to the pillow cover 5 described later.

  Reference numeral 4 denotes a three-dimensional lattice space material, which is placed on the upper part of the pillow material 2 housed in the inner bag 3. The three-dimensional lattice space material 4 has a thickness of approximately 10 mm and communicates with the air layer 4b. In order to maintain the above, a plurality of nylon and polyester blends or individual plastic yarns 4d are knitted.

  Then, as shown in FIG. 4A, the three-dimensional lattice space material 4 is arranged on the upper surface in contact with the head on the fine side of the lattice knitted into a hexagonal shape having a side of approximately 3.5 mm, as shown in FIG. As shown in FIG. 4, the lower side is provided with the larger side of the lattice that is woven into a hexagonal shape having a side of 7 mm. As shown in FIG. 4C, each side of the upper hexagon and each side of the lower hexagon When the head is placed on the pillow 1, the three-dimensional lattice space material 4 of the head is thick when the head is placed on the pillow 1, and is knitted with a plastic thread 4d having a diameter of about 0.2 mm between the sides. It has excellent air permeability so as to have an appropriate hardness that can be crushed to about 1/2.

  In addition, by making the fine side of the lattice face the upper surface side, it will turn over and turn sideways so that when the face comes in contact with the pillow 1, the lattice marks of the three-dimensional lattice space material 4 do not stick to the face. ing.

  Moreover, since the fine side of the lattice is arranged on the upper surface and the large side of the lattice is arranged on the lower surface, the weight of the head is set in the shape of the pyramid shape of the three-dimensional lattice space material 4. Since it receives, the buckling of a lattice part can be prevented and the three-dimensional lattice space material 4 with flexibility and a softness | flexibility can be comprised collectively.

  Further, since the ends of the outer peripheral edges of the three-dimensional lattice space material 4 other than the upper and lower surfaces are exposed, the ends of the cut yarn made of plastic are exposed, so that they are surrounded by a non-breathable or low breathable material seal 4c. It is fixed by means to prevent the cutting part from protruding, and safety is also taken into consideration.

  A knitted pillow cover 5 covers the entire pillow 1 so that the three-dimensional lattice space material 4 does not deviate from the pillow material 2 and has good touch, breathability and heat dissipation.

  The effect | action by the above structure is demonstrated.

  First of all, when using the pillow 1 in a predetermined position on the quilt and putting the head on the pillow 1 by sleeping, it will come in contact with the knitted pillow cover 5 with good touch, breathability and heat dissipation. It feels good.

  Furthermore, since there is a flexible and flexible three-dimensional lattice space material 4 on the pillow material 2 of the low-resilience polyurethane foam having good cushioning properties, a sufficient distance can be secured between the pillow material 2 and the ventilation material. Since both of these properties are good, the heat dissipation is good, the two are not too soft and not too hard, they are not too hard, and the cushioning property is good with a moderate hardness. Therefore, it is possible to provide a very comfortable pillow.

  Therefore, if you sleep in this state, it is comfortable and easy to turn over because it has good touch, breathability and heat dissipation, and good cushioning, even in the summer when it is difficult to sleep.

  At this time, by turning over, the position where the weight of the head is applied changes, and the pillow 1 side is in a non-ventilated state, but the head side is in an open state, so the air layer 4b in the three-dimensional lattice space material 4 Since the air in the air layer 4b is replaced by the pumping action caused by the narrowing or widening of the pillow, the pillow cover 5 is always kept fresh and comfortable.

  In addition, even if the face is turned sideways at this time and the face comes into contact with the pillow 1, the touch is good and the cushioning property is good. Is.

  Moreover, even if it becomes sideways, since the finer one of the lattice of the three-dimensional lattice space material 4 is on the upper side, there is no mark on the face.

  In the present embodiment, the three-dimensional lattice space material 4 is formed by knitting plastic yarn, but a three-dimensional lattice space having a communicating air layer such as a resin molded product or a bunch can be formed. Any material that is flexible and flexible can be used.

  Also, the pillow material 2 is made of low-resilience polyurethane foam. However, any material that can form a pillow, such as feathers, cotton, and a pipe made by cutting a plastic straw, may be used, and is limited to the operation of this embodiment. Is not to be done.
