[0017]

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 covered with a cloth, a urethane rubber sheet, and the like, and its peripheral edge (near 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. It is welded along this bending line so as to divide it into two parts, and as a result, the air chambers 6 and 7 of the A and B systems in which two comb teeth facing each other are alternately interwoven.
Is configured. The two places 3 and 3 where the flange 4 is not formed are provided with connection pipes 8 and 9 for communicating the air chambers 6 and 7 of the A and B2 systems with the outside, respectively. In the figure, 10 indicates a welded portion.

Further, a plurality of minute ejection holes 11 for ejecting a small amount of air in the air chambers 6 and 7 are provided on one surface (upper surface in FIG. 2) of the split mat 1. 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.

The divided mats 1 are arranged side by side as shown in FIG. 3 and connected by a connecting means described later. 3 in the figure
The divided mats 1 are connected to each other to form a completed floor-rubbing prevention mat.

Of the three divided mats 1, the connecting pipe 8 located to the left of the leftmost divided mat 1 in FIG.
A pump means 12 for sending air to each of the air chambers 6 and 7 is provided at 9.
Output tubes 13 and 14 are connected to each other, and the connecting pipes 8 and 9 on the right side of the split mat 1 on the rightmost side in the figure are closed by plugs 15 and 16, respectively, and the other connecting pipes 8 and 9 is the air chamber 6 and B of the A system of the adjacent mats
The system air chamber 7 is connected by connecting tubes 17 and 18 so that the B system air chamber 7 and the A system air chamber 6 communicate with each other. As a result, as shown in the figure, the A system air chambers 6 and the B system air chambers 7 are alternately arranged in the direction in which the split mats 1 are arranged. Note that, 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 is shown as a reverse of that shown in FIG. is there.

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. During this time, a small amount of air is ejected from the ejection hole 11.

Next, a connecting means for connecting the divided mats 1 will be described. As shown in FIG. 1 and FIG. 2, the flange 4 and the outer surface of the air chamber 6 on one end side of the upper surface of the split mat 1 (the side where the ejection holes 11 are supposed to be the upper surface) and the outer surface of the air chamber 6 respectively have concave connecting portions. Three concave fasteners 19 and three convex fasteners 20 serving as convex coupling portions are provided, and these concave fasteners 19 and convex fasteners 20 serve as a coupling member. Further, on the outer surface of the flange 4 on the other end side of the lower surface of the split mat 1 and the outer surface of the air chamber 6, a concave fastener 19 and a convex joint part which become concave joint parts so that the concave and convex relations are the same as those on the one end side. Three convex fasteners 20 are provided. The concave fastener 19 and the convex fastener 20 on the other end side serve as the members to be joined.

Here, in each drawing, both fasteners 19,
The convex fastener 20 is shaded so that the 20 can be easily distinguished.

The connection of each divided mat 1 as described above is shown in FIG.
Like. That is, the concave fastener 19 as a joining member on the upper surface flange 4 of one of the adjacent mats 1 and the convex fastener 20 as a joined member on the outer surface of the air chamber 6 on the lower surface of the other mat 1 are joined, The convex fastener 20 which is a coupling member on the outer surface of the air chamber 7 on the upper surface of the split mat 1 and the concave fastener 19 which is a coupled member on the flange on the lower surface of the other split mat are coupled.

In this way, since the flanges 4 of both split mats are joined to the outer surface of the air chamber of the other split mat, as shown in FIG.
4 There is no fall of the floor-rubbing prevention mat at the joining portion, that is, the joining portion, as when joining the mates. Therefore, the body does not sink at the connecting portion, and good sleeping comfort can be obtained. Figure 7
Then, a concave fastener 19 and a convex fastener 20 are provided on the upper and lower surfaces of the flange. This is so that the divided mats can be combined even when they are turned upside down.

Further, in the case of FIG. 4, since the air mates are joined at the outer surfaces of the air chambers of both of the adjacent mats, that is, at two places, as compared with the case where the flanges are joined as shown in FIG.
The binding force increases and it is hard to come off. In particular, in the case of a connecting member such as the concave fastener 19 or the convex fastener 20 or a member to be joined, it is easy to disengage from the force in the anti-joining direction shown by the arrow C in FIG. Since the direction in which 1 is disengaged (the direction of arrow D) is obliquely displaced with respect to the anti-coupling direction, it is also difficult to disengage from this point.

FIG. 5 shows another embodiment of the concave joint portion and the convex joint portion, in which a concave hook 21 and a convex hook 22 are used instead of the concave fastener 19 and the convex fastener 20. Similarly, the mats 1 and 1 easily disengage from a force in the anti-coupling direction (arrow C direction), but the mats 1 and 1 disengage (arrow D direction).
It is difficult to come off because it is slanted with respect to. When comparing the two, concave fastener 19 and convex fastener 20
It is more convenient to combine the split mats even if they are positioned slightly.

Next, a case where the vertical direction of the arbitrary divided mat 1 is reversed will be described. In this case, connect the connecting tubes 17 and 18 of the split mat that need to be inverted to the connecting pipes 8 and 9.
(If you want to invert the split mats at both ends, also remove the output tubes 13 and 14 and plugs 15 and 16), and flip the split mats around the axis that is parallel to the direction in which the split mats are arranged. . Then, the state of the concave and convex fasteners 19 and 20 of the adjacent split mats becomes the same as before the inversion, and the fasteners can be joined in the same manner as in FIG.
Then connecting tubes 17, 18 and output tubes 13, 14 and plugs
15 and 16 are connected again to the connecting pipes 8 and 9.

FIG. 6 schematically shows the case where the central split mat 1 is turned upside down from the state shown in FIG. 3, and the arrows in the figure show the directions of the air blown out from the jet holes 11.

The fact that the divided mats can be connected in the same manner even if the mats are turned upside down in this way means that, for example, if there is a mat that is heavily soiled or a mat that is severely damaged, it can be turned upside down as a temporary measure until repair or replacement. It can be used with the damaged or damaged part facing down.

Further, as in the above embodiments, the air ejection holes
If 11 is on only one side of split mat 1, spout 11
Can be freely selected above or below, so that the split mat corresponding to the part where floor rubbing occurs and the jet air needs to be applied is directed to the jet hole 11 and the split mat corresponding to the other part is not The jet hole 11 can be directed downward according to the above requirement, and it is particularly effective when the patient has heat and it is better not to blow the jet air, or when it is cold in winter.

[0032]

According to the invention of claim 1, since the flanges of the two adjacent mats are connected to the outer surface of the air chamber of the other mat, the flanges are connected to each other at the connecting portion. You can avoid falling of the mat of
As a result, there is no body depression at the connecting portion, and good sleeping comfort is obtained. In addition, since the mats are joined at two locations on the outer surfaces of the air chambers of the two adjacent mats, the joining force is increased and it is difficult for the mats to come off.

Further, according to the second aspect of the present invention, even if an arbitrary divided mat is vertically inverted about the direction orthogonal to the direction in which the divided mats are arranged, the divided mats are divided in the same manner as when they are not inverted. Mats can be combined, so if you have a mat that is heavily soiled or a mat that is severely damaged, you can turn it upside down and use it with the soiled or damaged part down as a temporary measure before repairing or replacing it. .

Further, according to the third aspect of the invention, the jet of air from the air chamber is applied only to a portion where floor rubbing occurs and it is necessary to apply the air, and the other portion is not hit according to the patient's request. This is convenient for the user.

Further, according to the invention of claim 4, it is possible to surely connect the split mats with a simple and inexpensive connecting means even if there is a slight displacement of the split mats, and at the same time the split mats are joined. Even if a force is applied to the mats in the horizontal direction to separate them from each other, the mat has a strong resistance force in this direction and can be prevented from coming off easily.
