DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air mat particularly suitable for the physically handicapped or bedridden.

[0002]

2. Description of the Related Art Air mats for bedding are lightweight and have good cushioning, can be compactly arranged when not in use, and are provided with a large number of pores on the surface to blow air out of the pores. It has advantages such as exhibiting a preventive action, and has been widely used in recent years especially for hospital beds. The thickness of a commonly used air mat is usually about 10 cm, and a plurality of binding sheets for holding the fabric on the front and back at regular intervals are arranged in the vertical direction.

[0003]

However, the above-described conventional air mat has a function as a bed, but cannot be used as a chair. Therefore, in the care of a sick or elderly person, the caregiver has to use the help of the caregiver every time the upper body is occasionally required to be in the upright posture, and the labor of the caregiver is enormous. In order to alleviate such labor, a bed for a sick person is provided in a hospital or the like, in which a gear bar is provided on a bed, and a bed portion supporting an upper body portion can be raised by rotating a handle. However, this bed is expensive and extremely difficult to dispose of when not in use or when it is no longer needed, making it unsuitable for personal use.

[0004] In order to improve the difficulty of such hospital beds, for example, Japanese Utility Model Application Laid-Open No. Sho 62-66631 or 62-66131.
As shown in Japanese Patent No. 54739, a triangular air bag is provided below the upper body support portion of the cushioning mat when inflated, and air is injected into the air bag to inflate the air bag when desired to raise the upper body support portion. Although a mat has been proposed that allows the sick person to inflate the air, it is extremely harsh, and in the absence of a caregiver, the sick person can easily get up and take a posture by simple operation. A simple air mat was strongly desired.
The present invention provides an air mat in which a sick person can temporarily take an upright posture by deflating the mat in order to meet such a demand.

[0005]

The air mat according to the present invention has a thickness when inflated sufficiently large to have a backrest function and partitions the inside thereof in the width direction to form an upper half air chamber and a lower half air chamber. Is formed. That is, the thickness of the air mat is at least 30 cm or more, and the inside of the air mat body is partitioned in the width direction at the portion where the part between the hip and the waist of the sleeping human body is located to form an upper air chamber and a lower air chamber. The upper body can be made upright by lowering the lower body by discharging air from the lower air chamber from the expansion state of both air chambers. The configuration is as follows.

[0006] The air mat is formed of a cotton fabric or a blended fabric having a rubber or synthetic resin film formed on the back surface, or a synthetic resin sheet or a base cloth made of a flexible non-breathable sheet having a film formed of rubber or synthetic resin. Inside the upper half air chamber and the lower half air chamber, a plurality of binding sheets are arranged at intervals in the width direction in order to keep the surface of the mat body horizontal. The binding sheet may be provided in the vertical direction.

[0007] It is important that the partition sheet for the upper half air chamber and the lower half air chamber be provided below the part where the part between the hip and the waist of the human body lying on his back and sleeping as described above is located. The vertical dimension ratio of the upper half air chamber and the lower half air chamber of the mat body is preferably about 4: 6. The thickness of the mat body is desirably about 30 to 50 cm. If the thickness is smaller than 30 cm, the backrest effect cannot be obtained. If the thickness is larger than 50 cm, not only the cost is increased but also anxiety occurs during use. . From the viewpoint of the backrest effect and economy, the range of 30 to 40 cm is preferable.

As described above, the air mat of the present invention has a much larger thickness than the conventional air mat, and can be used in a bed style. And if a large number of pores are provided on the surface side of the upper half air chamber and a small amount of air (feeling or not feeling to the skin) always blows out from these pores,
Of course, it is useful to prevent the bedridden elderly person and the sick person from rubbing the floor, and it is, of course, good to provide them in both upper and lower air chambers.

[0009]

In the inflated state in which air is injected into the upper half air chamber and the lower half air chamber, a bed-like bedding effect is exhibited, and a cushion characteristic of the air mat is exhibited, so that the user can sleep comfortably. When the user discharges the air in the lower air chamber in the supine position, the lower air chamber contracts in the thickness direction and a step occurs at the boundary with the upper air chamber, and the lower body descends to lower the upper body. When the buttocks are lowered most, the upper body is raised and the upper air chamber acts as a backrest.

1 shows an embodiment of the present invention. FIG. 1 is a partially cutaway perspective view of a mat body, and FIG. 2 is a schematic perspective view of the mat. 1 and 2, 1 is a mat body, 2
Is the top sheet, 3 is the back sheet, 4 is the front and rear sheets, and 5 is the left and right side sheets. These sheets 2, 3, 4, and 5 are air-tightly bonded and bonded so that they return in each air chamber. 6,6, width 110cm, total length 18
A rectangular parallelepiped mat body 1 having a height of 0 cm and a height of 33 cm is formed.

The mat body 1 is divided into an upper half air chamber 8 and a lower half air chamber 9 at a position of four tenths of the entire length, the inside of which is blocked off in the width direction by a partition sheet 7.
The two air chambers 8 and 9 are separately provided with air supply and exhaust ports 10 and 11 respectively.
Is provided. Although the arrangement position and structure of the air supply / exhaust ports 10 and 11 are not particularly limited, the air supply / exhaust port 11 of the lower half air chamber 9 is opened and closed, in particular, the opening operation for the exhaust is performed by pulling a string. In order to perform the exhaustion in a short time, a well-known exhaust device based on a positive intake (not shown) is provided for performing the exhaustion in a short time. Numerals 12 and 12 in the drawing denote binding sheets for holding a flat surface when the mat is expanded.

As described above, the air mat of the present invention has a thickness of at least 30 cm or more when inflated, and the air mat body 1 has an internal portion at the position where the portion between the hip and the waist of the human body is asleep. In the width direction, divided into an upper half air chamber 8 and a lower half air chamber 9 for 2 minutes.
9 are provided with air supply / exhaust ports 10 and 11, respectively. When desired, for example, only the lower air chamber 9 is evacuated so that the air chamber 9 can be contracted. When the air supply / exhaust port 11 of the chamber 9 is opened, the lower air chamber 9 contracts due to the weight of the lower body of the sleeping person, and accordingly the lower body lowers and the upper body rises as shown in FIG. The sitting position can be achieved, and the upper air chamber 8 can be used as a backrest. When the person becomes accustomed to such an operation, the sleeping person himself learns how to move the weight, and when he / she learns how to hang the weight when lowering the lower body, the upper air chamber 8 is also raised together with the upper body rising. This makes it possible to use the surface of the upper half air chamber 8 as a backrest surface.
