Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bed pad laid on an upper surface of a bed, and more particularly to a bed pad provided with flame retardancy and static electricity elimination to improve safety, health and hygiene. Bed pads that exhibit the same effect.

[0002]

2. Description of the Related Art Usually, a bed pad having a middle material sandwiched between side grounds is laid on a mattress upper surface of a bed, and sheets are covered on the bed pad.

[0003] As shown in FIG.
An intermediate material 10 made of various types of cotton materials that are lightweight and excellent in heat retention and air permeability, and the intermediate material 10 is sandwiched between upper and lower surfaces.
Generally, the side material 11 is made of a cloth material made of cotton or various fibers, and the middle material 10 and the side material 11 are integrally sewn with a quilting thread 12 of a multi-needle quilting process. Is being worn.

[0004]

However, in the case of a conventional bed pad, when a fire such as a sleeping cigarette comes into contact with the bed pad, it is ignited by a quilting thread or the like and burns to the middle cotton material. There is a problem that there is a risk of burning up, which may lead to a burning accident.

Further, in the conventional bed pad, the middle material and the side ground are integrally sewn by a multi-needle quilting process.
There has been a problem that the quilted yarn frays during use, and the appearance is poor. Furthermore, there were also problems that fibers and dust of the middle material blow out from the thread, and ticks enter.

Furthermore, the conventional bed pad has a problem in that static electricity is generated due to friction between the sheet and the bed pad during bed making. When static electricity is generated, not only unpleasant irritation is felt during work, but also house dust such as dust and dust floating in the air adheres to the bed pad and causes dirt. Also, during sleep, dust and dust attached to the surface, or dead mites or eggs, etc., enter the trachea of the human body and cause various etiologies such as bronchitis, asthma, allergic diseases and atopic diseases. . In addition, accidents such as electric shock and ignition due to sparks may occur due to the generation of static electricity when using a tumbler for dry cleaning.

[0007] In view of the above, the present invention prevents burning accidents during bedtime, prevents fraying of yarn and intrusion of house dust in the quilted part, and also eliminates static electricity to improve health and hygiene. An object of the present invention is to provide a bed pad that exhibits excellent effects and has excellent safety.

[0008]

In order to achieve the above-mentioned object, a bed pad according to the present invention comprises a bed pad laid on the upper surface of a bed, wherein a middle material inside the bed pad is formed of a flame-retardant material, The middle material and a side ground that sandwiches the middle material are bonded by ultrasonic quilting.

[0009] It is preferable that the side cloth is woven with conductive fibers for removing static electricity.

In the present invention, since the middle material is made of a flame-retardant material, even if a fire such as a cigarette or a match comes into contact with the bed pad, it does not burn in a short time and is generated during bedtime. Burning accidents can be prevented beforehand. Further, since the middle material and the side ground are bonded by the ultrasonic quilting process, the occurrence of thread breakage and fraying can be prevented. Furthermore, as described above, even if a fire such as a cigarette comes into contact, there is no risk of ignition from the quilted yarn.

Further, in the present invention, for example, static electricity generated during bed making can be removed by weaving conductive fibers for removing static electricity in the side ground. Therefore, unpleasant stimulation due to static electricity is not felt, and further, house dust such as dust and dust floating in the air does not adhere to the bed pad.

[0012]

Embodiments of the present invention will be described below with reference to the drawings. 1 is an overall perspective view of a bed pad according to the present invention with a part thereof cut off, FIG. 2 is an exploded sectional view of the bed pad, FIG. 3 is a sectional view of a bed pad bonded by ultrasonic quilting, and FIG. Represents cross-sectional views each showing a conventional bed pad.

The bed pad 1 comprises a bed mattress 13
Medium material 2 laid on the upper surface of the fire-resistant material
And a side ground 3 for holding the middle member 2 from the upper and lower surfaces. The intermediate material 2 in the present preferred embodiment is made of a flame-retardant material, for example, a flame-retardant polyester cotton as a main material, and is molded by mixing heat-fusible fibers. Has excellent breathability. In addition, in the middle material,
Other composition cotton may be used as long as the material has flame retardancy.

The intermediate member 2 and the side member 3 are integrally bonded at a welding portion 4 by ultrasonic quilting. The ultrasonic quilting processing is a processing technique for welding a plurality of layers of materials by frictional heat generated by ultrasonic energy, and has been conventionally known.

Unlike the conventional multi-needle quilting process, the ultrasonic quilting process does not use a quilting thread, so that the thread does not break even after long-term use. Further, it is possible to prevent ignition from the quilted yarn, which has been a problem in the past.

In the ultrasonic quilting process, since no quilting needle is used, there is no through hole between the materials. For this reason, it is possible to prevent the middle material 2 from blowing out and the mites from entering the inside. Although the ultrasonic quilting process is performed in a straight line in the drawing, the ultrasonic quilting process is not limited to the straight line and may be performed in a circular or curved shape.

Next, another preferred embodiment of the bed pad of the present invention will be described. In general, static electricity generated during bed making not only gives workers unpleasant irritation,
There was also a problem that the sleeping comfort was reduced during bedtime. In addition, recent studies have revealed that static electricity adversely affects human health.

Therefore, as another preferred example of the bed pad of the present invention, conductive fibers 5 for removing static electricity are woven at regular intervals in the side pad 3 of the bed pad 1.

As the conductive fiber 5, a carbon fiber yarn is used in a preferred embodiment of the present invention. By weaving the conductive fibers 5 into the side cloth 3 at regular intervals, the bed pad 1
Static electricity generated on the entire surface of the substrate can be discharged and removed. Note that the conductive fibers 5 are not limited to carbon fiber yarns, and any material that removes static electricity may be used.

By weaving the conductive fibers 5 into the side lining 3, no unpleasant stimulus is given to the worker during bed making. Furthermore, even during bedtime, comfortable sleeping comfort can be obtained.

In addition, it is possible to prevent so-called house dust, such as harmful dust and dust including dead mites floating in the near air, from adhering to the bedding and to prevent stains on bedding. Further, it is possible to reduce various etiologies such as allergic diseases and atopic diseases caused by inhaling the house dust during sleep. Furthermore, since the conductive fiber 5 such as a carbon fiber-based material has flame retardancy, it is possible to suppress the burning of the side land 3.

[0022]

As described above, the bed pad of the present invention has the following effects by adopting the above structure.

Since the middle material is made of a flame-retardant material, it does not burn in a short time even if a fire is brought into contact with the bed pad. Therefore, it is possible to prevent burning accidents that occur while sleeping.

Further, since the intermediate material and the side material are bonded by the ultrasonic quilting process, there is no need to use a quilting yarn, so that there is no occurrence of yarn breakage during long-term use. Also, it is possible to prevent ignition from the quilted yarn.

Further, since the ultrasonic quilting process is performed, there is no penetrating hole between the raw materials, and it is possible to prevent the middle material 2 from jumping out and the mites from entering the inside.

Further, by weaving conductive fibers for removing static electricity on the side of the bed pad, static electricity generated during bed making can be removed. By removing such static electricity, it is also possible to suppress the adhesion of dead mites and eggs, etc., floating on the air to the bedding, so that allergic diseases, atopy, and various etiologies such as bronchitis and asthma can be prevented. Can be suppressed. Moreover, since the conductive function of the conductive fiber does not deteriorate even after long-term use or repeated washing, the antistatic effect is maintained for a long time. Further, since the conductive fibers also have flame retardancy, it is possible to suppress the burning of the side lands and further improve the flame retardancy of the bed pad.
