Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a futon, and particularly to a sleeping futon.

[Prior Art] As is well known, a conventional sleeping comforter is formed by sewing an outer fabric and a lining fabric into a bag shape, and filling the inside with cotton, synthetic fibers, or feathers. The properties required of this futon include flexibility, heat retention, and breathability.

[Problem to be solved by the invention] In order to improve flexibility and heat retention in the above-mentioned futon, increasing the amount of fillers such as cotton and feathers results in poor breathability, which can be extremely difficult especially when a sick person sweats. It's hard to sleep.

Other conventional technologies include Utility Application No. 48-19072.
A microfilm photographing the contents of the specification and drawings attached to the application No. 49-120520 shows a rug with a plurality of through holes formed therein. However, since this technique involves forming countless small holes (through holes) in the board, it is impossible to apply it to futons. In other words, since there is a content called "cotton" inside the futon, simply forming a through hole will cause the content to expand and block the through hole, or to protrude from the through hole to the outside of the futon. This causes the problem of storage.

The present invention was proposed in view of the problems of the prior art as described above, and aims to provide a futon with improved breathability, flexibility, and heat retention.

[Means for Solving the Problems] The futon according to the present invention is provided with a plurality of through holes, and each of the plurality of through holes is formed in a portion of the futon where the through hole is to be formed. It is formed by applying a rigid circular quilting with a diameter larger than the diameter of the circular quilting, cutting off the radially inner part of the circular quilting, and sewing a cover cloth to the peripheral edge of the penetrated part formed by cutting off. The product is mixed with powder for far-infrared radiation.

It is preferable to arrange as many small-diameter through-holes as possible, but from the viewpoint of sewing technology, there should be at least 10 through-holes with a diameter of 2 to 5 cm, and at most 20 through-holes.
It is preferable to arrange 30 pieces.

Further, the futon in which through holes are provided can be either a mattress or a comforter, but in the case of a comforter, it is preferable that the holes are provided only in the upper part of the futon that covers the chest.

[Function] In the futon configured as described above, the front side and the back side of the futon are completely communicated through the through holes. Therefore, breathability is greatly improved and sweat evaporates effectively.

Further, even if the through holes are formed, the filling material of the futon will not block the through holes or protrude outside the futon through the through holes.

Furthermore, the powder for far-infrared radiation mixed in the filling emits far-infrared rays due to moisture in sweat, further improving breathability and warming the body.

[Examples] Examples of the present invention will be described below with reference to the drawings.

In FIG. 1, the mattress, which is designated as a whole by reference numeral 1, has a plurality of (30 in the illustrated example) through holes 2 arranged in a grid of 6 rows and 5 columns. Note that the reference numeral 7 in the figure indicates the quilting applied to the peripheral edge using a known sewing technique, and the filling (not shown) of the futon 1, such as cotton, is made using a known technique (Japanese Unexamined Patent Application Publication No. 1983-1998-1).
Contains powder for far-infrared radiation according to Publication No. 184088).

In the embodiment shown in FIG. 2, the mattress 1A has 28
The through holes 2 are arranged in five rows, shifted by half a pitch from row to row.

In the embodiment shown in FIG. 3, 20 through holes 2 are arranged in three rows in approximately one-third of the longitudinal direction of the comforter 1B, shifted by half a pitch from each other.

FIG. 4 shows details of the through holes 2, the diameter D of the through holes 2 is set to 2 to 5 cm according to the sewing technique described below, and the number of holes is at least 10 and at most for the same reason. It is preferable to take 20 to 30 pieces.

That is, as shown in FIG. 5, a hard circular quilting 3 having a diameter slightly larger than the diameter D of the through hole 2 is applied to the portion of the futon 1, 1A or 1B (hereinafter collectively referred to as 1) at the position of the through hole 2.

Next, as shown in FIG. 6, the raised inner portion 4 defined by the quilting 3 is cut off to form a cutout hole 5.

Finally, as shown in FIG. 7, the cover cloth 6 is sewn to the peripheral edge 5a of the cutout hole 5.

[Effects of the invention] Since the present invention is configured as described above, it produces the effects described below.

That is, a large number of holes communicate the front and back sides of the futon, greatly improving breathability without sacrificing flexibility or heat retention, and quickly evaporating sweat to improve sleeping comfort.

Furthermore, the powder for far-infrared radiation mixed in the filling emits far-infrared rays due to moisture in sweat, further improving breathability and warming the body to improve heat retention.

Claims (1)

[Scope of utility model registration request] A plurality of through-holes are arranged, and each of the plurality of through-holes is formed by applying hard circular quilting with a diameter larger than the diameter of the through-hole to the portion of the futon where the through-hole is to be formed. It is formed by cutting off the inner part in the radial direction of the circular quilting, and sewing a cover cloth around the periphery of the penetrating part formed by cutting off, and the filling contains powder for far-infrared radiation. A futon that is characterized by:
