Description

[Detailed Description of the Invention] Purpose of the Invention (Industrial Field of Application) The present invention relates to a mat whose backrest can be formed using air pressure.

(Prior art) When caring for a sick or elderly person who is lying in bed or on a futon in need of bed rest, it is often necessary to help a person get up and take a posture as necessary. It is extremely difficult to provide necessary nursing care while supporting the patient in a sitting position. For this reason, a bed that can be formed with a backrest has been devised and used to allow sick and elderly people who are lying on their backs to sit up when necessary.

(Problem to be solved by the invention) However, in conventional beds that can be formed with a backrest, it is difficult to use a gear mechanism to turn the backrest from a lying position into an upright position using a motor or a hand-cranked handle. common,
This inevitably complicates the mechanism and is extremely disadvantageous in terms of cost.

Structure of the invention (Means for solving the problem) Therefore, the present invention consists of a backrest made of a non-flexible member, a slip-preventing piece connected to the back side of the backrest, and One end of the male and female hook-and-loop fasteners is fixed near the connecting portion between the holding portion and the slip-prevention piece, one end of the male and female hook-and-loop fasteners is fixed to one edge of an inflatable and deflated air bag, and the air bag were removably connected and arranged between the backrest portion and the anti-slip piece to form a mat.

(Function) In other words, the backrest is normally stretched flat,
When air is supplied to the air bag by a suitable air supply device, the air bag is inflated into a predetermined shape, and the backrest shifts from the flattened state to the raised state. Therefore, the user on this mat, such as a sick person or an elderly person, moves from a lying down position to a standing position together with the backrest. As the air bag expands, the backrest is pushed toward the legs, but since the air bag is inflated on the anti-slip piece connected to the backrest, the entire mat is There is no risk of it shifting from its original position.

In addition, the air bag is removable and replaceable using a hook-and-loop fastener, and even if pressing force is applied to the air bag during installation, the male and female double-sided fasteners apply tension in the direction of rubbing against each other, ensuring maximum separation. Turn in a difficult direction.

This type of pine is extremely simple in structure,
It is also extremely advantageous in terms of cost.

(Example) Hereinafter, examples 1 to 5 that embody the present invention will be described.
This will be explained based on the diagram.

In this embodiment, four mat pieces 1, 2, 3, and 4 are connected so as to be bendable, and each of the mat pieces 1 to 4 is set to have the same width and different lengths. As shown in Figures 2 and 3, each pine piece 1~
4 is a plate-shaped core material 1a, 2a, 3a, 4a made of non-flexible synthetic resin or wood, and each plate-shaped core material 1a.
- Composed of cushion materials 1b, 2b, 3b, and 4b made of sponge or the like fixed on 4a, each of the plate-shaped core materials 1a to 4a and cushion materials 1b to 4b are covered and housed independently in a cloth cover 5. has been done.
That is, the connecting portion of each mat piece 1 to 4 is a part of the cloth cover 5, and therefore, each mat piece 1 to 4 is connected to a part of the cloth cover 5.
is bendable at the connection site. The first mat piece 1 serves as a backrest, the second mat piece 2 corresponds to the waist, and the third and fourth mat pieces 3 and 4 serve as leg rests.

A slip-off preventing piece 6 is connected near the connecting portion between the backrest portion 1 and the second mat piece 2. The anti-slip piece 6 is composed of a cloth cover 7 sewn to the cloth cover 5, and a plate-shaped core material 8 made of synthetic resin or wood and housed within the cover 7. Between the backrest part 1 and the slip prevention piece 6, a fastening piece 9 made of cloth is connected near the connection part, and a male or female hook-and-loop fastener 10 is fastened to the upper surface of the fastening piece 9. ing. Furthermore, an inflatable air bag 11 in the shape of a triangular prism is disposed between the backrest portion 1 and the anti-slip piece 6. A fastening piece 12 is connected to one edge of the bottom of the air bag 11,
As shown in FIG. 4, male and female hook-and-loop fasteners 13 are fixed to the lower surface of the fastening piece 12. By joining the double-sided fasteners 10 and 13, the air bag 11 is removably connected to the backrest portion 1 and the anti-slip piece 6, as shown in FIG.

As shown in FIG. 5, female and male hook-and-loop fasteners 14 and 15 are fastened to the lower surfaces of the third and fourth mat pieces 3 and 4 in the vicinity of the connecting portion thereof. An inflatable air bag 16 having a substantially cylindrical shape is disposed below the double-sided fasteners 14 and 15. A pair of fastening pieces 17 and 18 are provided on the upper surface of the air bag 16 in correspondence with the double-sided fasteners 14 and 15.
are connected symmetrically, and male and female hook-and-loop fasteners (not shown) are fixed to the upper surfaces of both fastening pieces 17 and 18. Then, by joining the hook-and-loop fasteners 14 and 15 on the side of the leg rests 3 and 4 and the hook-and-loop fastener on the side of the air bag 16, the air bag 16 is placed on the side of the leg rests 3 and 4 as shown in FIG. Detachably connected.

As shown in FIG. 1, a plurality of pipe-shaped air bags 19 are continuously divided and formed on the upper surface of the backrest portion 1.
An air mat 19 consisting of a is connected by a hook-and-loop fastener (not shown), and each pipe-shaped air bag 1
A distribution compressor 20 is connected to 9a. That is, the pipe-shaped air bladder 19a expands and contracts sequentially from the leg rests 3 and 4 side to the head side. Note that the air mat 19 is omitted in FIGS. 2 to 5.

Now, the mat of this embodiment is normally in the flattened state shown in FIG. 21 is a mattress. As shown in FIG. 1, if both the air bags 11 and 16 are connected to the supply port 22a side of the foot-operated air supply device 22 and air is supplied to both the air bags 11 and 16, the air bag 11
expands, and the backrest 1 rises along with this expansion. Along with this inflation, the backrest 1 is pushed toward the leg side, but since the inflation of the air bag 11 is carried out on the anti-slip piece 6, the backrest 1 and the sick person on the backrest 1 are , the weight of a user such as an elderly person passes through the air bag 11 and the slip prevention piece 6
act on top. That is, the anti-slip piece 6 connected to the backrest part 1 side has an anchor function, and the backrest part 1 is pushed toward the leg side by the expansion of the air bag 11.
is only rotated in the rising direction around the connecting portion between the back support portion 1 and the mat piece 2, and there is no fear that the entire mat will shift from its original position toward the leg side. Therefore, the user, such as a sick person or an elderly person, is always stably maintained in the original lying down position or standing up position, and there is no need to adjust the mat position. In particular, for users who require absolute rest, a misalignment of the mat position means hard work that must be corrected by the nurse at the mat position and the user's postural position at the same time. There is no fear like that of cigarettes. If the anti-slip piece 6 is omitted, the amount of deviation of the entire pine from its original position will accumulate as the pine alternately repeats the rising and flattening states.
It is unavoidable that the entire mat will shift significantly from its original position toward the leg side.

When the air bag 11 is expanded and formed into a triangular prism shape, the backrest portion 1 is held at a predetermined inclination angle. The air bag 11 has hook-and-loop fasteners 1 on both fastening pieces 9 and 12.
0 and 13, but since the fastening piece 9 can freely change the connection direction with respect to the backrest part 1 and the slippage prevention piece 6, a triangular prism-shaped air bag is connected from the backrest part 1 side. If a pressing force is applied to 11, double-sided fasteners 10 and 13 will face in the direction in which it is most difficult to separate them. Therefore, even if a pressing force is applied from the side of the backrest 1, the air bag 11 will not close to the backrest 1 and the anti-slip piece 6.
It will never leave your side.

On the other hand, the air bag 16 is expanded and formed into a substantially cylindrical shape,
The leg rests 3 and 4 form a chevron shape. Therefore,
The user of the mattress 21, such as a sick person or an elderly person, assumes a posture that matches the bent shape of the mattress, that is, a rising posture with the upper body raised and legs bent. Since the leg rests 3 and 4 are chevron-shaped, the upper body does not slide down on the backrest 1, resulting in good posture stability. Moreover, the flexed state of the legs is a more comfortable posture than the stretched state, and combined with postural stability, it is possible to stand up for a long time without any pain.

The mat of this embodiment, which allows the user to take such an easy standing posture, is extremely simple in terms of structure.
Compared to conventional beds that can be formed with a backrest, this method is easy to manufacture and extremely advantageous in terms of cost.

Further, in this embodiment, since the air mats 11 and 16 are removable, they can be easily replaced even if air leakage occurs.

In addition, in both the flattened state and the bent state of the mat of this embodiment, by operating the distributed compressor 20, it is possible to cause the user's back to perform a warping motion.

To make the mats flattened, both air bags 11,1
6 to the exhaust port 22 of the foot-operated air supply device 22
You can either connect it to b for forced exhaust, or disconnect it and let it exhaust naturally.

Of course, the present invention is not limited to the above-mentioned embodiments. For example, as shown in FIG.
A leg resting part is formed by two mat pieces 23,
A slip prevention piece 6 may be connected to the back surface of the leg rest 23, a piece of cloth without a core may be used as the slip prevention piece, or a shape other than a triangular prism that can hold the backrest 1 at a predetermined angle of inclination may be used. The air bag 11 may be formed in an expanded shape.

Effects of the invention As detailed above, the mat of the present invention can prevent the mat from shifting from its original position and maintain a stable posture for the user, and the air bag can be removed using a hook-and-loop fastener. Because the air bag is smooth, it can be easily replaced even if something goes wrong with the air bag, and even if pressing force is applied to the air bag during installation, the male and female double-sided fasteners apply tension in the direction of rubbing against each other. Since the air bag faces in a direction that is difficult to separate, the air bag will not come off accidentally.
In addition, the structure is very simple, easy to manufacture, and extremely advantageous in terms of cost.
