Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cover for an air mat which is used to prevent an air mat formed by arranging a plurality of bag-shaped air cells side by side from dirt or the like.

[0002]

2. Description of the Related Art There are various types of air mats. In particular, air mats requiring a cover are generally known to prevent pressure sores (bed sores) of sick persons and the like. For example, as shown in FIG. 4, an air mat 1 of this type has a bag-shaped air cell 2 on a base sheet 3.
The air cells 2 are arranged side by side so that air of an appropriate pressure is sent from the air pump 4 to these air cells 2 so that the contact pressure on the body of a sleeping person is suppressed to prevent pressure ulcers.

In this example, an air pump 4 is connected to an air cell 2
There are two air transfer paths, and the odd-numbered air cells 2a
The air is sent to the A-system cell comprising the air transfer path 5 via the air transfer path 5, and the air is sent to the B-system cell comprising the even-numbered air cells 2 b via the air transfer path 6. Then, the A-system cells and the B-system cells are alternately inflated and contracted via these air transfer paths 5 and 6 so as to change into a waveform in the length direction of the air mat 1 so as to be locally applied to a sleeping person. We try to prevent pressure sores by preventing the concentration of strong pressure from continuing to concentrate.

When the air mat 1 is actually used, the air mat 1 is put on a bed, for example, or a mattress is laid on a tatami mat and put on the mat. By the way, the air cell 2 is a material obtained by laminating a high-polymerized polymer film on a fabric, or a plastic film as it is, or a plastic film having a matte finish on the surface of the plastic film, and is formed into a substantially cylindrical bag shape. It is not a structure to sleep on. In addition, if it is soiled, it has a shape that is difficult to clean.

[0005] Therefore, when the air mat 1 is used with a cover, a sheet having the same width as the air mat 1 is hung on the air mat 1, and the front and rear ends of the sheet are folded under the air mat 1 for use. Since dust enters from the side, a dedicated sheet 20 is usually used as shown in FIG.
That is, a dedicated sheet 20 that is larger in front, rear, left and right (length and width) than the air mat 1 is used to cover the upper side of the air mat 1 and to be used with four front, rear, left and right ends folded under the air mat 1.

[0006]

However, as shown in FIG. 5, when the exclusive sheet 20 is used by folding its front, rear, left and right ends under the base sheet 3 of the air mat 1, firstly, the air The air tubes serving as the transfer paths 5 and 6 are obstructed by the obstruction, and are easily wrinkled. Second,
If the air mat 1 is not positioned in the center of the exclusive sheet 20, the end of the exclusive sheet 20 folded under the air mat 1 will not have an equal width, and the patient will move or change clothes on the exclusive sheet 20. Or when
The narrow folded portion is turned up and the sheet 20 becomes wrinkled, and the care is troublesome. In this case, a button may be attached to the end of the exclusive sheet 20 and the back side of the base sheet 3 of the air mat 1 so as to fix the button. However, it takes time to attach the button, and there is a problem in terms of cost. .

An object of the present invention is to provide an air mat cover which can be easily attached to an air mat, is hardly wrinkled, and does not allow dust and dirt to enter the inside.

[0008]

In order to solve the above-mentioned problems, the present invention employs the following means. The cover for an air mat according to claim 1 is made of an elastic fabric, has a box shape having an opening at a lower portion when it is spread, and has at least one of ridge lines formed by side surfaces. It is characterized in that a slit is formed in one ridge line.

According to this configuration, when the air mat is opened, it has a box shape having an opening at the lower portion. Therefore, when the air mat is mounted, the air mat is completely covered from above, and the lower portion is folded under the air mat to form a ridge. Pass the air tube that sends air from the air pump to the air mat using the slit. In this way, the slit through which the air tube for sending air passes is provided, so that the entire cover can be integrally formed, and no dust, dirt, or other dirt enters the inside, and the inside is clean. Can be kept,
Since the fabric is a stretchy fabric, wrinkles are more difficult,
Care can be reduced.

[0010] The cover for an air mat according to claim 2 is
It is made of stretchable fabric, is box-shaped with an opening at the bottom when it is spread, and the size of the opening is formed smaller than the size of the upper part, and it is formed by side and side The slit is formed in at least one of the ridge lines.

According to this structure, the size of the opening is smaller than the size of the upper part, and the cloth has elasticity. Therefore, when the cloth is attached to the air mat, the end of the opening is pulled. If it is spread and covered, the end of the opening can be naturally contracted and mounted, so that it is not necessary to take time and effort.

The air mat cover according to claim 3 is
In the invention of claim 1 or 2, the slit is formed as a gap without sewing a part of the ridge line when the side surfaces are sewn together.

According to such a configuration, since a component for forming a slit is unnecessary, the cost can be reduced.

[0014] The cover for an air mat according to claim 4 is
The invention according to claim 1 or 2 is characterized in that the slit is configured so that the side surface is stopped with a fastener, and a part of the ridge line is formed as a gap.

With such a configuration, although the cost for the fastener is increased, it is possible to cope with a change in the position of the air tube for sending the air.

[0016]

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

FIG. 1 shows an air mat cover 10 according to an embodiment of the present invention. The air mat cover 10 is made of polyester fiber, and is made of a stretchable and waterproof fabric. Because it is cloth,
In the folded state, the shape is not known, so that it is shown in an expanded state. 1A is a plan view, FIG. 1B is a front view, FIG. 1C is a bottom view, FIG. 1D is a side view, and FIG. 1E is an end view along line AA in FIG.

The inside of the air mat cover 10 is naturally hollow, and the upper portion 11 which covers the air mat from above is formed in a rectangular box shape, and the lower portion 12 is inverted trapezoidal. An opening 13 is provided at the bottom.
Are formed. In the upper part 11, the length L1 of the cover 10 (corresponding to the front-back direction of the air mat) is approximately 190 cm.
The width W1 is about 85 cm and the side depth D1 is about 12 cm
Is set to

The inverted trapezoidal portion of the lower portion 12 has a side surface depth D2 of about 17 cm, a length L2 of the opening 13 of about 160 cm, and a width W2 of about 55 cm. Reinforcing members 14 are sewn to the four corners of the opening 13, respectively, so that the seam between the side surfaces is not easily frayed even when the end of the opening 13 is pulled when the air mat is attached.

Also, two ridges 11a (in this case, at the left and right ends of the same side in the longitudinal direction) formed by the side and the side of the upper part 11 of the cover 10, and a slit 15 of about 7 cm in length are formed. Is provided. As shown in FIG. 2, the slit 15 is formed as a gap without stitching when suturing and joining the side surfaces. Of course, the surrounding area is reinforced so that it does not break down.

When the air mat cover 10 is mounted on the air mat, the end of the opening 13 is pulled and spread, the end of the air mat is passed through, and then the other end is pulled. After passing through the end, the end of the opening can be attached by naturally shrinking. Subsequently, the air tube for sending air from the air pump to the air mat is passed through the slit 15. In this way, since the slit for passing the air tube is provided, the entire cover can be integrally formed, the mounting is easy, and the fabric is a stretchable waterproof fabric, so that wrinkles are less likely to occur, and The inside can be kept clean without intrusion of dirt, dust, and other dirt.

In the above embodiment, the slit 15
Are provided at the left and right ends of the same side in the length direction, but may be provided at the left and right ends of the same side in the width direction.
When the position of the air tube of the air mat is determined, only one slit 24 may be provided in accordance with the determined position. Further, the slit 15 is formed as a gap without suturing the side when the side surfaces are sewn and joined together, but the slit 15 is not limited to this, and the left and right combs can be formed by sliding the slider. It is also possible to form a slit by sliding a slider by attaching a fastener of the type that meshes with the tooth-shaped member, or arrange a number of flexible hook-shaped members on one side and this hook-shaped member on the other side. A slit may be formed by attaching a fastener having a large number of locking members for locking, a so-called magic tape. In this case, the cost for the fastener is increased, but it is possible to cope with a change in the position of the air tube that sends air.

In the above-described embodiment, the waterproof fabric is used as the material of the cover for the air mat. However, the present invention is not limited to this, and a fabric having no waterproof property may be used in consideration of usage. .
