Description

[Detailed Description of the Invention] [Purpose of the Invention] (Field of Industrial Application) The present invention relates to a bed rug, and is used for constructing bed pads, mattresses, etc., for example.

(Prior Art) As a conventional technique of this type, a technique disclosed in Japanese Utility Model Application Publication No. 54-62810 is known.

Generally, when using this conventional rug, the user lies on the same side of the rug all year round, regardless of the temperature or temperature of the four seasons. In other words, rugs have not been used in such a way that the front and back sides of the rug can be reversed to suit the changing seasons.

(Problems to be Solved by the Invention) The present application attempts to solve the above-mentioned problems by the following means. Namely, (1) The filling of the rug has a two-layer divided structure.

(2) One side of the two layers was formed by thermally welding 15 to 20 denier thick fibers (polyester, etc.) synthetic cotton etc. with low melting point polyester to form a hard layer with large voids (hereinafter referred to as A). ).

(3) The other side of the two layers is made of synthetic cotton made of fine fibers (polyester, etc.) of 4 to 6 deniers and heat-welded using the same method as in A above to form a soft layer that contains a large amount of dead air (hereinafter referred to as B). ).

(4) A cloth was applied to the front side of each of A and B, and a nonwoven fabric was applied to the back side, and A was finely quilted and B was coarsely quilted.

(5) The quilted A and B facing each other were sewn or joined.

(Function) Since one side of the batting of the present invention has a large void, it has good air permeability (convection), is hard, and maintains a certain degree of rigidity resistance.

The other side of the batting has a lot of dead air, so it has less heat dissipation, is soft, and has appropriate adaptability to loads.

(Example) An example of the present invention will be described based on FIGS. 1 and 2. The first embodiment is an application of the bed rug of the present invention to a bed pad. Fig. 1 shows the cotton on one side (the side suitable for summer), and Fig. 2 shows the cotton on the other side (the side suitable for winter). 3 is quilting, 2,
4 indicates edge tape.

The bed pad according to the first embodiment consists of a two-layered pad. Of the two layers, the center of the summer layer is a hard thin cotton layer with a thickness of about 5 mm, made by heat-welding a 30 denier polyester synthetic surface with low melting point polyester. This hard and thin cotton layer is sandwiched between a surface fabric and a nonwoven fabric, and then layered and finely quilted as shown in FIG. 1 to form a summer layer.

The center of the winter layer is a soft, thick cotton layer with a thickness of about 20 mm made by heat-welding a 6-denier polyester synthetic surface with low-melting polyester.
This summer layer is sandwiched between a surface fabric and a nonwoven fabric and overlapped, and rough quilting is applied as shown in FIG. 2 to form a winter layer.

The above-mentioned summer layer and winter layer were sewn together so that the nonwoven fabrics faced each other, and the periphery was sewn together with edge tape to form a bed pad.

According to the bed pad of the first embodiment, since the summer layer is made of a hard and thin cotton layer with fine quilting, even if a person lies on it, the body will not sink into the layer. Therefore, the contact area between the body and the rug is small, creating a gap between the rug and the body.
Therefore, when used in the summer with this layer on top, it provides good ventilation, high heat dissipation, and provides a cool and comfortable sleeping experience.

In addition, the winter layer has appropriate flexibility, so
It wraps the body softly and does not create any extra gap between the rug and the body. Therefore, the winter layer has heat retention properties and provides the user with a warm and comfortable sleeping experience.

Next, a second embodiment of the present invention will be described based on FIG. Similarly to the first embodiment, the second embodiment is an application of the present invention to a bed pad. The bed pad of the second embodiment is composed of a pad with a four-layer structure,
One side has a summer layer and the other side has a winter layer. The plane of the summer layer is finely quilted as in the first embodiment, and its plane is similar to that shown in FIG. Further, the winter layer is roughly quilted as in the first embodiment, and its plane is similar to that shown in FIG.

FIG. 3 shows a sectional view of the bed pad of the second embodiment. FIG. 3 shows a more preferred form of the invention. As shown in FIG. 3, the summer layer 5 is
A thin hydrophilic polyester cotton layer 8 is overlaid on a hard thin cotton layer 9 with a thickness of about 5 mm, which is made by heat-welding 30 denier polyester staples and rayon staples with low melting point polyester, and the surface fabric 7 is hydrophilic. A nonwoven fabric 10 is laminated integrally on the soft polyester cotton layer 8 and on the hard and thin cotton layer 9. Fine quilting 11 is applied to the thus stacked layers to form the summer layer 5.

The winter layer 6 has a thin hydrophilic polyester cotton layer 13 overlaid on a soft cotton layer 14 with a thickness of about 20 mm, which is made by heat-welding 6 denier polyester staples and rayon staples with low melting point polyester. The surface fabric 12 is on the hydrophilic polyester cotton layer 13, and the nonwoven fabric 15 is on the soft cotton layer 14.
It is laminated in one layer on top of the . Rough quilting 16 is applied to the thus stacked layers to form the winter layer 6.

The summer layer and winter layer produced in this way are
The nonwoven fabrics were sewn facing each other, and the periphery was sewn together with edge tape to form a bed pad.

According to the bed pad of the second embodiment, the summer layer 5 has a structure in which a hydrophilic polyester cotton layer 8 is layered on a finely quilted hard and thin cotton layer 9. However, the body does not sink down much. In addition, the hydrophilic polyester cotton layer 8
Due to the hydrophilic action of the hard and thin cotton layer 9, water on the surface of the rug is quickly absorbed, and the user does not feel uncomfortable due to stickiness.

In addition, in the winter layer 6, since the soft cotton layer 14 has appropriate flexibility, it softly wraps the body and does not form an extra gap between the rug and the body. For this reason,
The winter layer has heat retention properties, providing the user with a warm and comfortable sleeping experience.

Furthermore, the hydrophilic polyester cotton layers 8 and 13 disposed above the summer layer 5 and the winter layer 6 are easy to dry, and the moisture absorbed while sleeping is dried when not in use, so you can enjoy a comfortable nightly sleep. It can provide sleeping comfort.

[Effect of idea]

The bed rug of the present invention contains a low melting point polyester in the polyester synthetic cotton layer, and the fibers are thermally welded by applying heat at the desired temperature, so voids are formed due to the bond between the fibers. has been done. Therefore, by changing the mixing ratio of low melting point polyester, the thickness of the fiber can be adjusted.
The hardness of the fiber layer can be adjusted without changing the density of the fibers.

As a solution to the drawbacks of the conventional technology, it may be possible to change the hardness of the needle cotton used so far and use it differently for summer and winter. However, the use of needle cotton increases the weight, making it very difficult to handle during daily lifting and drying operations, etc.

In the present invention, the summer layer prevents the user's body from sinking due to the reasons described in the section of structure and function. The contact area between the body and the back fabric is reduced, and the gap between the rug and the body is maintained appropriately. Therefore, if you use this one side in the summer, you will have a cool and comfortable sleeping experience due to good ventilation and high heat dissipation. Furthermore, since the summer layer is made of thick fiber synthetic cotton heat-welded with low melting point polyester, it can have hard and large voids between the fibers. Air convection is likely to occur within this large gap, which also provides excellent heat transfer, or heat dissipation, and provides a cool sleeping experience.

Furthermore, since the other side has appropriate flexibility, it wraps around the body and does not create an extra gap between the rug and the body. Furthermore, since the winter layer is made by welding fine fiber synthetic cotton with low melting point polyester, the fibers are finely intertwined and can have small, soft voids. Air convection is difficult to occur within this small gap, making it difficult to transfer heat. Therefore, it retains body heat and provides a warm sleeping experience.

In addition, since the conventional technology used a needle surface, it was heavy, produced fiber waste, and was easily dislocated.However, in the present invention, a low melting point polyester is used and a method of thermally welding the fiber staple is adopted, so that the above-mentioned conventional technology is not possible. Eliminates all defects and makes sewing work easier.

In addition, since it is quilted, there is no movement of cotton, the initial state is maintained, and there are many secondary effects such as easier cleaning.
