Abstract

PURPOSE: To obtain a pleasant environment for sleeping by constituting an air blowing bedding of a plurality of contact-bonded parts formed by contact bonding of the second fabric, the second mat layer, the first fabric, the first mat layer and the third fabric in this order by avoiding channel parts, an air blasting means and a duct for making an opening part communicate with the above described air blowing means. CONSTITUTION: An air blowing path 9 is constituted of the first fabric 3 and the third fabric 8 by making areas of the first fabric 3 and the second fabric 5 larger than those of the first mat layer 2 and the second mat layer 4 and bonding tightly the surroundings of the first fabric 3 and the second fabric 5 with the third fabric 8 treated by gas impermeableness treatment. An opening part 10 formed on a part of the air blowing path 9 and a flexible duct 11 connecting this with a blower 1 are arranged. In addition, a lamination constituted as described above is contact-bonded by ultrasonic treatment by avoiding channel parts 6. As the mat parts comprise a flexible substance, it is easily stored and it exhibits good moisture absorption by using a hard cotton and there exists no possibility of giving unpleasant feeling even when a user sweats.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to blower bedding that cools a sleeping environment by blowing air.

BACKGROUND OF THE INVENTION As shown in FIGS. 3a and 3b, a conventional blower bedding of this type includes an air supply device 15 consisting of an air supply vibrator 14 provided with a plurality of air exhaust holes 13, and an air supply device 15. an air compressor 16 that sends air to the
The air compressor 16 blows out air from the air exhaust hole 13 to blow air to the human body. (For example, Japanese Unexamined Patent Publication No. 58-121917) Problems to be Solved by the Invention However, in the above configuration, since a vibrator is used in the ventilation path, it is difficult to fold it and it is difficult to store it when not in use. Because the vibrators are connected in series, the amount of air blown out differs between locations near and far from the air compressor.Also, since the air path cannot be made large, a compressor must be used to ensure sufficient air volume. However, there was a problem in that the noise and vibration during operation were large, and this became a factor that disturbed sleep.

The present invention solves these conventional problems and aims to provide a comfortable sleeping environment using bedding that is lightweight and easy to store.

Means for Solving the Problems In order to solve the above problems, the ventilation bedding of the present invention includes a first mat layer having end portions and a plurality of grooves penetrating through the end portions formed on the back surface; a first fabric that is in close contact with the entire surface of the mat layer and has larger dimensions than the first mat layer; and a second mat that is in close contact with the surface of the first fabric and has approximately the same dimensions as the first mat layer. a second fabric that adheres closely to the surface of the second mat layer and has similar dimensions to the first fabric;
from the second fabric to the second mat layer and the first
a plurality of blow-off holes penetrating through the A 0 ground to the groove position of the first mat layer; and the first and second A 1 ground and end portions provided below the second mat layer; a third fabric joined together; a ventilation passage formed by the first fabric and the third fabric; an opening provided in a part of the ventilation passage; a plurality of crimped parts formed by crimping the second mat layer, the first fabric, the first mat layer and the third iro fabric in this order while avoiding the groove; a blowing means; and the opening. and a duct that connects the air blower and the air blowing means.

Effect of the present invention With the above-described structure, the air blown by the blowing means fills the ventilation path through the duct to form a kind of chamber, and is sent from there to the grooves on the back of the mat, so that the air is evenly distributed from the blow-off holes in each part of the mat. You can blow out air. Furthermore, since it is lightweight, it is easy to move, store, and install.

Example Embodiments of the present invention will be described below with reference to the accompanying drawings.

In FIGS. 1 and 2, 1 is a blower, 2 is a first mat layer made of hard cotton, a chemical fiber, and on the surface of the first mat layer 2 is a non-breathable first fabric 3, A second mat layer 4 made of hard cotton with good hygroscopicity and a second fabric 5 are stacked one on top of the other in order, and grooves 6 that pass through the first mat layer 2 from end to end are formed by ultrasonic processing. A plurality of blow holes 7 are provided at the positions of the grooves 6, and further, a plurality of blow holes 7 are provided that penetrate from the first mat layer 2 to the second fabric 5. The first fabric 3 and the second fabric 5 are the first mat layer 2 and the second mat layer 4.
By bringing the first fabric 3 and the second fabric 5 into close contact with the third fabric 8 which has been treated to be non-breathable, the first fabric 3 and the third fabric 5 are A ventilation passage 9 is constituted by the cloth 8. 10 is an opening provided in a part of the ventilation passage 9, and 11 is a flexible duct connecting the opening 10 and the blower 1. Further, as in the above structure, the second fabric 5, the second mat layer 4, the first fabric 3 and the first
A plurality of crimped parts 12 are provided by laminating the mat layer 2 and the third fabric 8 in this order and crimping them by ultrasonic processing while avoiding the grooves 6.

In the above structure, since the mat part is made of a flexible material, it is easy to store, and the use of hard cotton has good moisture absorption, so even if the user sweats, it will not cause discomfort. Never.

Further, when grooves 6 are formed on the back side of the first mat layer 2 by ultrasonic processing, grooves are also formed on the front side of the second mat layer 4, and when forming the crimp portions 12 by ultrasonic processing, grooves are also formed on the front side of the second mat layer 4. Since the recesses are formed on the front side of the second mat layer 4, the front side of the second mat layer 4 is also uneven, so that the user does not come into close contact with the surface of the bedding, and breathability is ensured. Therefore, you can feel comfortable using it even in summer.

Further, by providing the crimp portion 12 by ultrasonic processing, the third fabric 8 is fixed to the first mat layer 2, so the fabric can be easily fixed without using adhesives or sewing. . Furthermore, since the back of the bedding is also uneven, the back of the bedding does not come into close contact with the floor, ensuring breathability, so the bedding does not deteriorate due to moisture or develop mold or dust mites, making it comfortable to use. be able to.

Here, hard cotton, a scientific fiber, was used for the mat layer, but
It may also be molded with resin such as urethane foam.

In addition, in the practical example described in -H, the blower 1 sucks indoor air and blows the air, but the blower 1 may have a built-in electric heater and blow out hot air. It has a fast heating effect and is effective in collecting heat in winter, as well as drying bedding.

In the above embodiment, the second mat layer 4 is made of hard cotton with good hygroscopicity, but it may also be made of fibers that have been treated with antibacterial and deodorizing properties and have good hygroscopicity. Even if used for a long time, it can prevent bacteria from forming or unpleasant odors, so even bedridden people can use it comfortably.

Effects of the Invention As described above, the blower bedding of the present invention provides the following effects.

(1) Since the grooves are provided on the back of the mat, the grooves can be large enough to reduce air resistance in the ventilation path, and the low-noise blower blows enough air to make the human body feel cool. can be done.

(2) The air blown by the blowing means fills the ventilation path through the duct, forming a kind of chamber, and is sent from there to the grooves on the back of the mat, making it possible to blow air evenly to each part of the mat, making it easier for the user to The airflow evenly hits each part of the body, giving an even cooling effect to the whole body.
