BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air mat particularly suitable for physically disabled people and bedridden patients.

0002

[Prior Art] Air mats for bedding are lightweight, have good cushioning, can be compactly organized when not in use, and have a large number of pores on the surface to blow out air from the pores. It has the advantage of having a preventive effect, and has been widely used in recent years, especially for hospital beds. The thickness of a commonly used air mat is usually around 10 cm, and it is constructed by longitudinally arranging a plurality of binding sheets to hold the front and back fabrics at regular intervals.

0003

[Problems to be Solved by the Invention] However, although the above-mentioned conventional air mat has a function as a mattress, it cannot be used as a seat. Therefore, when caring for a sick person, an elderly person, etc., if the patient occasionally wants to raise his or her upper body in an upright position, the caregiver must rely on the help of the caregiver each time, and the caregiver's effort is enormous. In order to alleviate such labor, beds for patients are used in hospitals, etc., in which a gear frame structure is provided on the bed, and the bed part supporting the upper body part can be raised up by rotating a handle. However, this bed is not only expensive, but also 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 drawbacks of hospital beds, for example, Japanese Utility Model Application No. 62-66631 and No. 62-62-
As seen in Japanese Patent No. 54739, an air bag which forms a triangular shape when inflated is provided below the upper body support part of the cushion mat, and when desired, air is injected into this air bag to inflate it, thereby raising the upper body support part. Mats have been proposed, but the work of injecting air into the patient himself is extremely arduous, and in the absence of a caregiver, mats that allow the patient to get up and take up a standing position by simple manipulation have been proposed. There was a strong demand for a simple air mat. In order to meet such demands, the present invention provides an air mat that allows a patient to temporarily assume a standing position by deflating the air from the mat.

[0005]

[Means for Solving the Problems] The air mat according to the present invention has a thickness sufficiently large when inflated to have a backrest function, and its interior is partitioned in the width direction into an upper half air chamber and a lower half air chamber. It forms. 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 area between the buttocks and the lower back of a sleeping human body, and is divided into an upper half air chamber and a lower half air chamber. The upper body can be brought into an upright position by lowering the lower body by discharging the air from the lower half of the air chamber when both air chambers are inflated. It is configured like this.

[0006] Air mats are made of cotton fabrics or blended fabrics with a rubber or synthetic resin film formed on the back side, synthetic resin sheets, or flexible non-breathable sheets with a rubber or synthetic resin film formed on the base fabric. 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 maintain the surface of the mat main body horizontally. Note that this binding sheet may be provided in the vertical direction.

[0007] As mentioned above, it is important that the partition sheet between the upper half air chamber and the lower half air chamber be located below the area between the buttocks and the waist of a person lying on their back while sleeping. The vertical dimension ratio of the upper half air chamber and the lower half air chamber of the mat main body is preferably about 4:6. The thickness of the mat itself is preferably about 30 to 50 cm; if the thickness is less than 30 cm, the backrest effect cannot be obtained, and if it is larger than 50 cm, not only will the cost be high, but it will also cause a feeling of anxiety when using it. . In view of the backrest effect and economy, a range of 30 to 40 cm is preferable.

As mentioned above, the air mat of the present invention has a much larger thickness than conventional air mats, and can be used as a bed. Then, if a large number of pores are provided on the surface side of the upper half air chamber, and a small amount of air (to the extent that you can feel it on your skin) is constantly ejected from these pores,
Of course, it is useful for preventing bed sores for bedridden elderly people and sick people, and it goes without saying that it is good to provide it in both the upper and lower half-air chambers.

[0009]

[Function] In the inflated state when air is injected into the upper half air chamber and the lower half air chamber, it acts like a bed-like bedding and exhibits the cushioning properties unique to an air mat, allowing you to sleep comfortably. When the user is in a supine position and exhausts the air in the lower half air chamber, the lower half air chamber contracts in the thickness direction and a step is created at the boundary with the upper half air chamber, causing the lower half of the body to descend and the upper half to When the buttocks are at their lowest point, the upper half of the air chamber acts as a backrest while erecting the upper body.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The figures show an embodiment of the present invention, with FIG. 1 showing a partially cutaway perspective view of the mat main body, and FIG. 2 showing a schematic perspective view of the mat. In Figures 1 and 2, 1 is the mat main body, 2
is a top sheet, 3 is a back sheet, 4 is a front and rear sheet, and 5 is a left and right side sheet, and each of these sheets 2
, 3, 4, and 5 are airtightly joined and bonded 6 and 6 to allow circulation in each air chamber, and the width dimension is 110 cm and the total length is 180 cm.
A rectangular parallelepiped mat body 1 with a height of 33 cm and a height of 33 cm is formed.

The interior of the mat main body 1 is cut off in the width direction by a partition sheet 7 at a position of 4/10 of the total length, and is divided into an upper half air chamber 8 and a lower half air chamber 9.
Both air chambers 8 and 9 have separate air supply and exhaust ports 10 and 11, respectively.
is provided. Although the arrangement position and structure of the air supply and exhaust ports 10 and 11 are not particularly limited, the air supply and exhaust port 11 of the lower half air chamber 9 can be opened and closed, especially for the purpose of exhaust, by pulling a string, for example. It is desirable to have a structure that can be easily carried out by the following methods, and in order to perform exhaustion in a short time, a known exhaust system using positive air intake is installed, although not shown in the drawings. In the figure, reference numerals 12 and 12 are binding sheets for maintaining a flat surface of the mat when it 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 main body 1 has an inner surface in the area between the buttocks and waist of a sleeping human body. is divided in the width direction into an upper half air chamber 8 and a lower half air chamber 9, and both air chambers 8,
9 are provided with air supply and exhaust ports 10 and 11, respectively, so that when desired, for example, only the air in the lower half air chamber 9 can be evacuated and the air chamber 9 can be contracted. When the air supply/exhaust port 11 of the chamber 9 is opened, the lower half of the air chamber 9 contracts due to the weight of the sleeper's lower body, and as a result, the lower body lowers and the upper body stands up as shown in FIG. It can be placed in a sitting position, and the upper half air chamber 8 can be used as a backrest. As the sleeper gets used to this kind of movement, he or she learns how to shift his or her weight, and when he or she learns how to apply weight when the lower body is lowered, the upper air chamber 8 is also raised up when the upper body is raised. This makes it possible to use the surface of the upper half air chamber 8 as a backrest surface.

[0013] Also, those who cannot perform such operations can use the surface of the upper half air chamber 8 as a backrest by pulling the upper half air chamber 8 slightly upward without falling down. Furthermore, if you want to actively use the surface of the upper half air chamber 8 as a backrest surface, as shown schematically in FIG. It is preferable to provide a support air bag 13 such that when the upper body stands up, air is supplied to the air bag 13 to inflate it, thereby raising the upper half air chamber 8 and maintaining the upright state.

[0014]

Effects of the Invention As described above, the air mat according to the present invention has a thickness of at least 30 cm or more, and the air mat main body 1 has a width that is equal to or smaller than the width of the inside where the part between the buttocks and the lower back of a sleeping human body is located. Upper half air chamber divided into 8 directions
The mat is divided into a lower air chamber 9 and a lower half air chamber 9, and each of the air chambers 8 and 9 is provided with a separate air supply/exhaust port. Since it is more than double the size, it can not only be used like a bed, but also has excellent cushioning properties. Furthermore, by simply removing the air from the lower half air chamber 9 while sleeping on the back, the lower half of the user's body can be lowered and the upper half of the user's body can be erected, as described above. Acts as a backrest. Furthermore, the mat itself is lightweight and significantly cheaper than hospital beds, so it can be easily used in ordinary homes, and has advantageous effects.
