Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mat for preventing pimples, so-called floor rubs, which occur in the bodies of bedridden patients and the elderly.

[0002]

2. Description of the Related Art Conventional floor rubbing prevention mats are disclosed, for example, in Japanese Unexamined Patent Publication (Kokai) No. 5-146470 (A61G7 / 05) and Japanese Utility Model Laid-Open No. 4-114.
As shown in FIG. 5 of Japanese Patent No. 323 (A61G7 / 05), one completed floor rubbing prevention mat is formed by arranging and connecting a plurality of division mats each having an air chamber inside. It has been known. The air chamber of each split mat is composed of a plurality of systems (in this case, two systems) of air chambers independent of each other, and the air chambers of these two systems are repeatedly arranged in the direction in which the split mats are arranged in parallel. By alternately sending air from the pump to the air chamber, expansion and contraction are alternately repeated row by row. And 2
The air chambers of the system are connected by connecting tubes so that the air chambers are alternately arranged and repeat expansion and contraction one by one even when viewed across adjacent divided mats.

In such a case, when a part of the mat is soiled or a part of the mat is broken due to incontinence of a patient or the like, only the split mat that is soiled or torn is repaired or replaced without replacing the entire mat. It is convenient to do this.

However, if the air chambers of each split mat are incorrectly connected by the above-mentioned connecting tube, two rows of inflating and contracting parts at the connecting portions of the adjacent split mats will expand and contract at the same time, resulting in a change in sleeping comfort. When it contracts, the dent in that part expands, and a part of the body falls into this dent and is pressed against the hard base or tatami mat etc. where the mat is placed, resulting in easier blood congestion and weaker floor rub prevention effect. There was a problem.

[0005]

SUMMARY OF THE INVENTION According to the present invention, a plurality of divided mats having a plurality of air chambers, which are independent of each other and are supplied with air alternately, are arranged in parallel to form one completed floor rubbing prevention mat. Therefore, the air chambers of a plurality of systems are arranged so as to be repeatedly arranged in the juxtaposed direction of the divided mats even when viewed across adjacent divided mats, that is, the expansion and contraction are repeated one row at a time, and two rows are erroneously simultaneously. An object of the present invention is to provide a mat for floor scuffing which does not expand or contract.

A further object of the present invention is to provide a floor-rubbing-preventing mat which is easy to handle by reducing the number of parts when connecting the split mats.

[0007]

The first means of the present invention is to:
A plurality of divided mats having air chambers formed therein are arranged in parallel and connected to each other, and the air chambers of the respective divided mats are constituted by a plurality of independent system air chambers that are sequentially and repeatedly arranged in the juxtaposed direction. The system is provided with pump means for alternately supplying air to the air chambers of each system, and at the end of the split mat, connecting ports of different shapes are provided which communicate with the air chambers of each system, and the air chambers of each system are provided. So as to be sequentially arranged in the juxtaposed direction across adjacent divided mats, a plurality of connecting tubes for connecting a pair of connecting ports of the adjacent divided mats to each other are provided, and both ends of these connecting tubes are connected to each other. It has a shape that matches only the connection port to be formed.

The second means of the present invention is to integrate a plurality of connecting tubes for connecting the connecting ports of the adjacent divided mats in the central portion thereof.

[0009]

According to the first means of the present invention (the invention of claim 1), the shape of the connection port of the air chamber of each system is different, and the connection tube can connect only a pair of connection ports to be connected. As a result, since the air chambers of the plurality of systems are repeatedly arranged in the juxtaposed direction of the divided mats even when viewed across adjacent divided mats, that is, the expansion and contraction are repeated one row at a time, and There is no accidental expansion and contraction of two rows at the same time due to a connection error.

According to the second means of the present invention (the invention of claim 2), since a plurality of connecting tubes for connecting the connecting ports of the adjacent split mats are integrated, storage management is easy and lost. Hard to do.

[0011]

The present invention will be described with reference to the drawings. 1 and 2
Is a split mat 1 which is a component of the floor rub prevention mat.
The split mat 1 is composed of two upper and lower rectangular soft sheets 2, such as a vinyl chloride sheet whose surface is lined with a cloth or a urethane rubber sheet, and its peripheral edge (at one end on one side). A flange 4 is formed by welding (excluding a certain two places 3 and 3), and a portion surrounded by the flange 4 is formed by a meandering bending line 5 whose both ends are located in the centers of the two places 3 and 3, respectively. The air chambers 6 and 7 of two independent A and B systems are formed by welding along the bending lines so as to divide them into two parts, and as a result, two comb teeth facing each other are alternately interdigitated. In the figure, 10 indicates a weld having a slightly wider width, and the weld having a narrower width is indicated by a single line.

The divided mats 1 are arranged side by side as shown in FIG. 3 and connected by a connecting means which will be described later (in the figure, one floor mat which is completed by connecting three divided mats 1 is prevented. The air chambers 6 and 7 of the two systems are sequentially and repeatedly arranged in the juxtaposed direction of the divided mat 1.

At the two places 3, 3 which are the ends of the split mat 1 on which the flange 4 is not formed, the connection ports 8 for communicating the air chambers 6, 7 of the A and B2 systems with the outside, respectively. , 9 are provided. As shown in FIG. 5, the connection ports 8 and 9 have a cylindrical tip end shape, while the connection port 9 has a prismatic shape and has different shapes.

On one surface (upper surface in FIG. 2) of the split mat 1, a plurality of fine ejection holes 11 for ejecting a small amount of air in the air chambers 6 and 7 are provided. No jet holes are provided on the surface opposite to the one surface. In the figure, the ejection hole 11 is shown in a large size for easy understanding.

Next, a connecting means for connecting the divided mats 1 will be described. As shown in FIG. 1 and FIG. 2, three concave fasteners 19 are provided at one end of the upper surface of the split mat 1 (the side where the ejection holes 11 are provided is the upper surface), that is, the flange 4, and the lower surface of the flange 4 is provided. Three convex fasteners 20 are provided on the back side of the concave fastener 19. Further, at the positions facing the concave and convex surfaces of the one end flange on the upper and lower surfaces of the other end flange 4 of the split mat 1 and the two convex fasteners 19 and 20, respectively, three convex surfaces are provided so that the concave-convex relationship with the one end flange is opposite. A fastener 20 and a concave fastener 19 are provided. Here, in each drawing, the convex fastener 20 is shaded so that the two fasteners 19 and 20 can be easily distinguished.

The connection of such divided mats 1 is shown in FIG.
As shown in. That is, the flanges 4 of the adjacent split mats 1 are bent downward as shown in the drawing to face the concave fasteners.
19 and the convex fastener 20 are joined. By doing so, the connecting portion, that is, the connecting portion of the split mat is hidden below, so that the connecting portion does not hit the patient lying on the mat, and the patient does not feel uncomfortable, and good sleeping comfort is obtained.

Next, the supply of air to the air chambers 6 and 7 of the split mat connected as shown in FIG. 3 will be described. Of the three split mats 1, the output tubes 13 of the pump means 12 for sending air to the air chambers 6 and 7 are connected to the connection ports 8 and 9 on the left side of the leftmost split mat 1 in FIG. , 14 are connected to each other, and the connection ports 8, 9 on the right side of the split mat 1 on the rightmost side in the figure are closed by plugs 15, 16, respectively. The output tubes 13 and 14 and the plugs 15 and 16 are shaped so as to match only the connection ports 8 and 9, respectively.

The other connection ports 8 and 9 are, as shown by the two-dot chain line in FIG. 4, the air chamber 6 of the A system and the air chamber 7 of the B system of the adjacent mats, and the air chamber 7 of the B system. And A
Connection tubes 17, 18 so that the air chamber 6 of the system communicates
Connected by. That is, the shape of both ends of the connection tube 17 is
One side 21 has a columnar shape that matches the connection port 8 and the other side 22 has a prismatic shape that matches the connection port 9, and the shape of both ends of the connection tube 18 is that one side 23 has a prismatic shape that matches the connection port 9. The other
24 has a cylindrical shape that matches the connection port 8 so that only a predetermined combination of connection ports can be connected.

As a result, as shown in FIG.
The system air chambers 7 are arranged alternately in the direction of arranging the divided mats 1 across the adjacent divided mats. That is, the adjacent air chambers of the adjacent split mats are always air chambers of different systems, and the air chambers of the same system are not erroneously arranged in two rows.

Incidentally, in FIG. 3, the air chambers 6 and 7 of the central split mat are connected to the split mats on both sides by connecting tubes 17 and 18, so that the split mat alone is shown in reverse. It is displayed.

The pump means 12 can alternately send air to the A system air chamber 6 and the B system air chamber 7 by a switching valve (not shown), and as a result, the A system air chamber 6 and the B system air chamber 6 can be sent. The system air chamber 7 alternately repeats expansion and contraction. As described above, since the adjacent air chambers of the adjacent split mats are always the air chambers of different systems, there is no possibility that two rows will simultaneously expand or contract across the adjacent split mats.
Expansion and contraction are repeated alternately row by row.

Therefore, when two rows are inflated and contracted at the same time, the sleeping comfort is changed, and especially when contracted, the depression of that portion is expanded, and a part of the body is depressed in this depression to place the mat. There is no fear that it will be pressed against a base or tatami mat, resulting in blood congestion, and the effect of preventing floor rub will be kept good.

A small amount of air is ejected from the ejection holes 11 to improve the floor rub prevention effect.

Further, as shown in FIG. 6, the connecting tubes 17 and 18 are integrated by entwining the central portions thereof with the connecting ribs 25. As a result, the connecting tubes 17 and 18 are not disjointed and are not easily lost. Therefore, it becomes easier to store and the handleability is improved.

The divided mat 1 can also be used by inverting it. That is, the connecting tubes 17 and 18 of the split mat to be inverted are removed from the connection ports 8 and 9 (when the split mats at both ends are inverted, the output tubes 13 and 14 and the plugs 15 and 16 are also removed), and the split The divided mats are reversed with the direction in which the mats are arranged side by side and the direction perpendicular to the mats as axes. Then both concave and convex fasteners 19,
The state of 20 is the same as before the reversal, and the coupling portion can be connected downward as shown in FIG. After that, the connection tubes 17 and 18, the output tubes 13 and 14, and the plugs 15 and 16 are connected to the connection ports 8 and 9 again.

From this fact, when a part of the floor-rubbing prevention mat is soiled or damaged, the split mat of this part must be replaced. However, when the alternative split mat is not prepared, the alternative mat is prepared. In the meantime
As a first-aid measure, the dirty or damaged split mat can be turned upside down (with the clean, undamaged side facing up). Further, even if it is turned upside down, the connecting portion can be connected with the back side, so that the user does not feel uncomfortable.

Further, since the jetting holes 11 are provided only on one surface of the split mat, the split mat corresponding to the portion where floor rub is generated and the jetted air needs to be applied, has the jetting holes 11 directed upward, and the other portion. The split mat corresponding to
You can freely use it according to your wishes, such as by turning down.
