Description

The present invention relates to an apparatus for preventing misalignment between a duvet cover and a futon that prevents the inadvertent misalignment of the futon cover and the futon by engaging the futon cover and the futon with frictional force.

There existed patent document 1 as a prior art. That is, a quadrangular opening is formed on the upper surface of the duvet cover body along the periphery thereof, and right-angled triangular cloth pieces are attached to each corner of the opening, and both end portions of the oblique sides of each cloth piece are attached. In some cases, each cloth piece was formed with a rhombus or square futon insertion / removal hole at the center of the hypotenuse of each piece of cloth, and an elastic material was attached to each hypotenuse to make the hypotenuse extendable.

In the above-described conventional one, the futon cover and the inner futon can be in close contact with each other, thereby preventing positional deviation between them. However, a wide quadrangular opening is formed on the upper surface of the duvet cover body, a right-angled triangular cloth piece is attached to each corner of the opening, and an elastic material is applied to the oblique side of each cloth piece. Since it was to be mounted, the structure was complicated, requiring a lot of manufac- turing, and expensive.

It is an object of the present invention to obtain a position misalignment prevention device between a duvet cover and a futon that makes the structure simple and makes it difficult for the both to be displaced by bringing the futon cover and the futon into contact with each other via a friction material. .

In the invention according to claim 1, a small piece of friction material made of a soft resin, synthetic rubber, or the like is provided on at least one of the futon cover and the surface sheet of the futon covered by the duvet cover. It is configured to be fixed integrally with an interval.
According to a second aspect of the present invention, the friction material is formed in a hemispherical shape having a diameter of 2 mm to 4 mm, and the friction material is scattered at intervals of about 10 mm.

In the invention according to claim 1, when the futon is covered with the futon cover, the frictional substance fixed to one surface comes into contact with the other surface, and the frictional force between the two is increased. Thereby, both become difficult to shift. In addition, since the friction material is a small piece and is fixed to one surface at a predetermined interval, the air permeability of the duvet cover and the futon can be maintained well, and these structures (bag shape) The frictional force of both can be increased without being influenced by ().

In the invention according to claim 2, since the friction material is a hemisphere having a diameter of 2 mm to 4 mm, and the friction material is interspersed at an interval of about 10 mm, the friction force between the comforter cover and the comforter is reduced. While maintaining the predetermined value, the opening ratio of the futon cover and the face sheet of the futon becomes high, and these air permeability is well maintained. Furthermore, since the frictional material is hemispherical, the area to be fixed to the cloth with respect to the amount of the frictional object is increased, and the frictional object is firmly fixed to the cloth.

The above friction material can be easily obtained by dripping (applying) an appropriate amount of uncured soft resin, synthetic rubber, etc. at predetermined intervals onto the cloth used as the futon cover or the surface sheet of the futon, and curing it. Can be formed.

Embodiments of the present invention will be described below with reference to the drawings. 1 is a plan view showing a first embodiment of the present invention, FIG. 2 is an enlarged sectional view taken along line II-II in FIG. 1, FIG. 3 is a partial sectional view taken along line III-III in FIG. FIG. 5 is a plan view showing a second embodiment of the present invention, FIG. 5 is an enlarged sectional view corresponding to FIG. 2 showing a third embodiment of the present invention, and FIG. 6 is a perspective view showing the fourth embodiment of the present invention.

1-3, 1 is a futon cover, and 5 is a futon covered with a duvet cover. The futon cover 1 is formed in a rectangular bag shape by a breathable sheet, and the right side portion thereof can be opened and closed by a fastener 2. The fastener 2 may be provided on the left side.

A large number of frictional objects 3 are scattered and fixed on the inner surface of the futon cover 1. The friction material 3 is made of a soft resin, synthetic rubber, or the like, and has a hemispherical shape with a diameter of 2 mm to 4 mm, preferably about 3 mm, as shown in FIGS. 2 and 3, and the friction material 3 has an interval of about 10 mm. It is scattered in a zigzag pattern.

The futon 5 is formed by forming a rectangular and bag-like surface sheet 5a from a sheet having air permeability, and filling the surface sheet 5a with a heat insulating material 5b such as cotton or feathers.

FIG. 4 shows a second embodiment. This is formed by crossing a linear friction object 3a in a rhombus shape at an interval of about 10 mm on the entire inner surface of the duvet cover 1.

FIG. 5 shows a third embodiment. In this case, a hemispherical friction material 5c is dotted and fixed to the outer surface of the top sheet 5a of the futon 5 in the same manner as in the first embodiment. The friction material 5c may be fixed by crossing a linear object in a diamond shape at an interval of about 10 mm as in FIG.

FIG. 6 shows a fourth embodiment. In FIG. 6, 4 is a futon collar cover. The futon collar cover 4 is formed into a short bag shape in the front and rear, covering the collar part (front part) of the futon 5 with a breathable sheet, as shown in FIG. 4b. A hemispherical friction material 4b is dotted and fixed to the entire inner surface of the futon collar cover 4. As in the first embodiment, the friction material 4b is formed in a hemispherical shape of about 3 mm, and is fixed in a staggered manner at intervals of about 10 mm.

The friction material 3 (3a, 4a, 5c) described above is preliminarily sewn with the futon cover 1, the futon 5, and the futon collar cover 4, and an uncured soft resin, synthetic rubber, or the like is predetermined on the cloth (sheet). Are formed by dropping (applying) an appropriate amount of each of them at an interval and curing them.

In addition, the shape, interval, and size of the friction material 3 (3a, 4a, 5c) are the material of the futon cover 1, the futon collar cover 4, and the surface sheet 5a of the futon 5, the size of the cloth, or the friction material 3 ( 3a, 4a, and 5c) are appropriately set. Moreover, you may make it this invention adhere | attach the hemispherical or linear frictional material 3 (3a, 5c) on both the inner surface of the futon cover 1 and the outer surface of the surface sheet 5a of the futon 5.

According to the said Example, when the futon 5 is accommodated in the duvet cover 1, the friction material 3 (3a) fixed to the inner surface side of the futon cover 1 will contact | abut the outer surface of the surface sheet 5a of the futon 5, for example. Become. Thereby, both engage with a high frictional force, and the futon 5 does not move carelessly in the duvet cover 1. Further, the friction material 3 (3a) is hemispherical or linear, and is fixed at a predetermined interval. Therefore, the opening ratio of the fabric eyes is not lowered so much and the air permeability of the duvet cover 1 is reduced. Can be maintained well. In addition, the friction force is not affected by the structure (bag shape) of the futon cover 1, for example, a futon cover or the like in which a rhombus or a rectangular insertion / removal hole is formed at the center of the upper surface. Can be high.

In addition, the friction material 3 (3a, 4a, 5c) is formed with a predetermined amount of uncured soft resin, synthetic rubber, or the like on the cloth (sheet) before the duvet cover 1, the futon 5 and the duvet collar cover 4 are sewn. Thus, the friction material 3 (3a, 5c) can be formed efficiently and easily.

It is a top view which shows 1st Example of this invention. It is an expanded sectional view by the II-II line of FIG. It is a fragmentary sectional view by the III-III line of FIG. It is a top view which shows 2nd Example of this invention. It is an expanded sectional view equivalent to FIG. 2 which shows 3rd Example of this invention. It is a perspective view which shows 4th Example of this invention.
