Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bed mat capable of adjusting the position of an air bag for supporting a waist in a bed and adjusting the height of the air bag by pressurizing and depressing the air bag.

[0002]

2. Description of the Related Art In a conventional bed mat of this type, as shown in Japanese Utility Model Laid-Open Publication No. 1-12859, the air bag supporting the waist supports not only the waist but also the buttocks and the scapula. And the actual opening 57-1798
Although there is an air bag having a different waist thickness as in No. 66, there is no space at the upper and lower ends in the longitudinal direction of the bed mat, and the position of the air bag is fixed. Therefore, unless a person sleeps in accordance with the position of the air bag, the air bag supporting the waist does not fit the waist.

[0003]

As described above, since the waist air bag is not structured to support only the waist, or is fixed even if it is structured to support only the waist, the air bladder is maintained at the waist even if no one sleeps. A match was needed, and the air bag could be moved and adjusted to fit the curve of each person's waist.

[0004]

According to the present invention, an adjusting member is inserted into a space provided in at least one of one end and the other end in the longitudinal direction inside a bed mat body. It is a bed mat whose position can be adjusted.

[0005] With this configuration, the position of the air bag can be moved according to the height of each person, and the waist can be supported in a state where the air bag is just fitted to the curve of the waist, so that comfortable sleep is possible. .

Further, since the air pressure of the air bag supporting the waist can be freely adjusted, the height of the air bag can be adjusted to a desired height, and the weight can be distributed to the buttocks, the scapula, and the waist, and it can be applied to a part of the body. You can sleep comfortably with less pressure and pressure.

[0007]

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

FIG. 1 is an external view of a bed mat.

The body 20 of the bed mat can be opened and closed by a mirror surface 1 which has been subjected to a quilting process or the like by a fastener 4 provided on an upper part of the exterior body 3 in the height direction. When the fastener 4a is provided on the side surface of the bed mat 20 as shown in FIG. 6, the adjustment member 6 can be moved in and out from the side surface, which is more convenient. Inside the exterior body 3, frames 5a, 5b, 6a made of an elastic material that does not feel uncomfortable even when sleeping like a bed mat with urethane foam 2 or the like,
6b is installed internally. The frame body is composed of 5a and 5b constituting the right and left sides of the outer peripheral portion, a frame body 6a on the head side, and a frame body 6b on the foot side. The air bladder installed in the space surrounded by the frames 5a, 5b, 6a, and 6b includes a head air bladder 7, a waist bladder 8, and a foot bladder 9. Head air bag 7,
A hose 10 is connected to the waist air bladder 8 and the foot air bladder 9 and is connected to an air filling means. An elastic material, for example, urethane foam 2 made of urethane foam or the like is installed on the upper part of the head air bag 7, the waist air bag 8, and the foot air bag 9, that is, the lower part of the mirror surface 1, and feels the bag (stiffness, wrinkles). Etc.) and improve air permeability.

Next, in the present invention, FIGS. 7 and 8 show the width of the waist air bladder 8 installed in the waist curved portion when the pressure is increased and when the pressure is reduced. The waist air bag 8 is variable in height by several centimeters above and below the head air bag 7 and the foot air bag 9 by filling and discharging air, and can be adjusted to a sleeping position where each person feels comfortable. It is assumed that. Since it is provided to fit the curve of the waist freely, its width ab
The gap must support only the lower back. If a single air bag is used to support the buttocks other than the lumbar region and the scapula as in the prior art, it is easy for the patient to congest and to put extra weight on the lumbar spine. This is because comfortable sleep cannot be obtained. Inside the main body 20 of the bed mat, a space located on one side in the longitudinal direction, that is, on the side of the frame body 6a on the head side, and a space located on the other side in the longitudinal direction on the side of the frame 6b on the foot side. The adjusting member 6 adjusts and holds the position of the waist air bladder 8 in the longitudinal direction of the main body 20. The adjusting member 6 is arranged in accordance with the position to be adjusted.
Is to select the number of sheets arranged on each head side and foot side.

Regarding the position adjustment of the waist air bag 8, FIG.
An example of a person of average height, FIG. 10 shows an example of a person who is shorter than the average, and FIG. 11 shows an example of a person who is taller than the average. In the case of FIG. 9, the number of the adjusting members 6 to be packed on the divided head side is the same as the number of the adjusting members 6 placed on the foot side.
The adjusting member 6 has a width of about 2 cm in the lateral direction, and can be taken in and out one by one. As described above, the position adjustment is performed by opening the mirror surface 1 or the side surface of the exterior body 3 with one of the fasteners 4 and 4a.

FIG. 10 shows a state in which a part of the adjustment member 6 located inside the divided head-side frame 6a is shifted to the inside of the foot-side frame 6b, and the position of the waist air bag 8 is changed to a pillow. This is an example of adjustment in the direction. FIG. 11 shows that, contrary to the case of FIG. 10, a part of the adjustment member 6 located inside the frame 6 b on the foot side is shifted to the inside of the frame 6 a on the head side. This is an example in which the position is adjusted in the foot direction. With the above adjustment, the waist airbag 8 can adjust the position of the main body 20 in the longitudinal direction without changing the position of the bedding such as the pillow. In the embodiment, the adjustment member 6 is shown to be adjusted by arranging it on both sides of the head frame 6a and the foot frame 6b. However, the head frame 6a and the foot frame are adjusted according to the adjustment position. In some cases, the adjustment member 6 may be disposed on one side of the frame 6b.
Further, the feature of the structure for taking the adjusting member 6 in and out is that the sleeping person does not need to move on the bed mat 20.
