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 floor slippage of a person who has been asleep for a long period of time, and more particularly, a mat for preventing floor slippage by allowing air pressure to massage and dry the body. It is about.

[0002]

2. Description of the Related Art As a conventional floor slip prevention mat as described above, for example, there is a "floor rubbing prevention mat" proposed in Japanese Patent Publication No. 4-206060. As described in the claims of the above-mentioned publication, this conventional floor-rubbing prevention mat "consists of three bag-shaped bodies made of flexible sheets to form a mat body, and these bag-shaped bodies are formed. Each of the three bag-shaped bodies is provided with an air inlet, an air supply means for alternately expanding and contracting two bag-shaped bodies among these three bag-shaped bodies is provided, and a large number of air ejection holes are provided in the remaining bag-shaped bodies. A mat for preventing floor rubs, characterized by being provided with an air continuous supply means for continuously supplying air to the bag-like body and a means for stopping the air supply or an adjusting means for arbitrarily changing the air supply amount ""With a rational configuration, the body does not block the ejection holes, and not only the massage action but also the drying action due to the air ejection can be performed reliably, but it is possible to selectively use both of these actions. In addition, the purpose is to provide a mat for floor scuffing which can be set to a desired hardness and can spout a desired amount of air and can effectively prevent and treat floor scrubbing. " It is a thing.

By the way, as shown in FIG. 8, this conventional "floor-rubbing prevention mat" is constructed as one continuous bag-like body 1b having a large number of air ejection holes 4 which meanders in a narrow meandering manner. Therefore, when the user's buttocks etc. are placed on a part of them and a large force is applied, the bag-shaped body 1
Since b is also formed in a flat shape by a flexible sheet, the portion to which the force is applied may be crushed. If this happens, air will not be supplied to the bag-shaped body 1b on the downstream side of this crushed portion, and the drying action due to air ejection cannot be performed reliably. This is because the bag-shaped body 1b having the air ejection holes 4 is supplied with air only from one end thereof.
This is because b must be meandered in a wide area in order to dry the entire body of the user.

Also, this conventional "mat for preventing floor scuffing"
In the case where the weight of the user is heavy, the other two bag-shaped bodies 1a are the same as in the bag-shaped body 1b described above.
There is a case where a so-called "floor phenomenon" occurs in which a crushed portion occurs. This is because the mat is made of a flexible sheet such as a vinyl sheet, and each bag-shaped body 1a and 1b.
And the three bag-shaped bodies 1.1.1 are formed as shown in FIGS. 8 and 9.
This is because they are connected as "single-layered" to form a so-called flat mat body.

In other words, the mat body formed by connecting the three bag-shaped bodies 1.1.1 made of flexible sheets supports the human body in a sleeping state in a plane. However, the weight of the human body is not evenly and evenly applied to such a wide area of the mat body, and as a result, this When the "mat" is used, the mat body is partially exerted with force. For this reason, the bag-shaped body made of the flexible sheet is crushed in the portion to which the force is applied, and the "floor phenomenon" occurs.

Once the "floor phenomenon" occurs, even if air is supplied into each bag, air will flow to other parts before the part where the floor phenomenon occurs is inflated.
Unless the air is supplied at a pressure at which the bag-like body is likely to burst, it is impossible to completely inflate the portion where the "floor phenomenon" has occurred. Therefore, in this conventional "floor-rubbing prevention mat", there are cases in which the massage action and the drying action due to the air jet cannot be reliably performed.

Therefore, the present inventors have made various studies on how to prevent the "floor sticking phenomenon" from occurring in the floor slip prevention mat made of this kind of flexible sheet. As a result, the inventors have newly found that the mat main body having a three-dimensional structure produces a good result, and completed the present invention.

[0008]

[0018]

The operation of the floor slip prevention mat 100 according to each claim having the above-described structure will be described below. The floor slip prevention mat 100 of the first embodiment is substantially the same as the inventions according to claims 1 and 2. In addition, since the floor slip prevention mat 100 according to the second embodiment substantially includes the inventions according to claims 3 and 4, the operation of the floor slip prevention mat 100 shown in each embodiment will be mainly described below. Explained.

(Floor slip prevention mat 100 according to the first embodiment
First, since the floor slip prevention mat 100 according to the first embodiment has the mat main body 10 formed by stacking three flexible sheets 11 to 13 in order from the top,
When air is not supplied into the upper air bags 21 and 22 and the jet air supply layer 25, the floor slip prevention mat 10
The mat body 10 of No. 0 has a thin flat plate shape. Therefore, the flat mat main body 10 can be made extremely small in volume by winding or folding the whole by utilizing the flexibility of each sheet constituting the flat mat main body 10. The packaging, storage, and transportation work can be done easily.

In order to use such a mat body 10, as shown in FIG. 4, the connection pipes 32 are connected to the respective connection ports 17 (there are three in total), and the air from the air supply device 30 is supplied. Is supplied to the upper air bags 21, 22, the lower air bags 23, 24 and the jet air supply layer 25 through the distributor 31, the mat body 10 has two air layers as shown in FIG. It becomes a so-called mat-like shape in which the layers are stacked. Then, by the action of the air supply device 30 or the distributor 31, air is supplied to the upper first air bag 21 and the upper second air bag 22 by alternately repeating air supply and air discharge. In addition, the jet air supply layer 25 is continuously supplied with air corresponding to the jet of air from the air jet holes 26.

By the above operation, the mat body 10 concerned
On the upper surface side of, the upper first bladder 21 or the upper second bladder 22 alternately expands or contracts,
The massage effect for the user is exhibited.
Further, during this time, since the air supplied from the air ejection holes 26 into the ejection air supply layer 25 is ejected upward, the back side of the user, for example, is dried.

At this time, it is important that the upper air bags 21 and 22 that exert a massage action on the user are
That is, it is in a state of being elastically supported by the blast air supply layer 25 immediately below it. That is, since the upper air bags 21, 22 are supported by the flat jet air supply layer 25 having a predetermined elasticity, the weight of the user by the upper air bags 21, 22 is increased. Is locally applied, the force is interfered by the blast air supply layer 25, so that the upper air bag 2
The "bottom phenomenon" in 1.22 does not occur at all.

Further, the blast air supply layer 25 is one plane that supports the entire upper air bags 21 and 22 from below, and moreover, the blast air supply layer 25 is connected to the blast air supply layers 25, respectively. The air ejection hole 26 is also the upper air bag 21.
Since it is spread over the entire space between 22 and a part of the air ejection hole 26 is ejected by the user's body or the like, the drying action by the air ejection is surely performed. In other words, even if the air supply to the injection air supply layer 25 is only one place, unlike the conventional one shown in FIG. 8, each air ejection hole 26 has a surface on the lower surface side. Since the air to be jetted is constantly supplied through the jet air supply layer 25 that is spreading in a wide range, there is a bottoming phenomenon in a part of the jet air supply layer 25, and the air jet holes 26 in that portion Even if air is not blown out,
Air is ejected from an air ejection hole 26 somewhere.

In particular, the shape of each upper air bag 21, 22 is
As in the floor slip prevention mat 100 according to claim 2, when the upper air bags 21 and 22 are configured as a diagonal line or a zigzag shape in which they are combined,
Since the blast air supply layer 25 supports the upper air bladders 21 and 22 entirely and three-dimensionally, even if local gravity is applied to the upper air bladders 21 and 22, the force is not enough. It is dispersed by the jet air supply layer 25.

In other words, in the conventional device shown in FIG. 8 or FIG. 9, when the weight of the user is locally applied, a bottoming phenomenon occurs in the bag-shaped body 1 at that portion. However, the floor slip prevention mat 10 of the present invention
In 0, even if a local force is applied to the upper air bags 21 and 22 and the upper air bags 21 and 22 are about to be crushed, the so-called "retraction place" of the upper air bags 21 and 22 is prepared by the jet air supply layer 25 in the above-described state. The upper bladder 2
1.22 is not completely crushed.

As described above, in the floor shift prevention mat 100 according to the first embodiment, the upper air bags 21 and 22 are provided.
In addition, since the bottoming phenomenon does not occur in the blast air supply layer 25, the massage action by the upper air bags 21 and 22 and the drying action by the air ejection from each air ejection hole 26 are always ensured. .

(Floor slip prevention mat 100 according to the second embodiment
About) Floor slip prevention mat 100 according to the second embodiment
Since the four flexible sheets 11 to 14 are stacked in this order from the top to form the mat body 10, the upper air bags 21 and 22, the lower air bags 23 and 24, and the jet air supply layer. When air is not supplied into the mat 25, the mat main body 10 of the floor slip prevention mat 100 has a thin flat plate shape. Therefore, the flat mat main body 10 can be made extremely small in volume by winding or folding the whole by utilizing the flexibility of each sheet constituting the flat mat main body 10. The packaging, storage, and transportation work can be done easily.

Now, in order to use the mat body 10 as described above, as shown in FIG.
To connect the air from the air supply device 30 to the distributor 31.
Via the upper air bag 21,22, lower air bag 23,24
If the air is supplied into the blast air supply layer 25, the mat body 10 becomes a so-called mat-like structure in which three air layers are vertically stacked, as shown in FIG. Then, by the action of the air supply device 30 or the distributor 31, air supply and air discharge are alternately repeated for the upper first bladder 21 and the upper second bladder 22, while the lower first Only air is supplied to the first air bag 23 and the lower second air bag 24 so that the pressure therein is constant. In addition, the jet air supply layer 25 is continuously supplied with air corresponding to the jet of air from the air jet holes 26.

By the above operation, the mat body 10 concerned
On the upper surface side of, the upper first bladder 21 or the upper second bladder 22 alternately expands or contracts,
The massage effect for the user is exhibited.
Further, during this time, since the air supplied from the air ejection holes 26 into the ejection air supply layer 25 is ejected upward, the back side of the user, for example, is dried.

At this time, it is important that the upper air bags 21 and 22 which exert a massage action on the user are
At the same time as being elastically supported by the blast air supply layer 25 immediately below the blast air supply layer 25,
That is, it is elastically supported by the lower air bags 23 and 24 on the lower side. That is, since the upper air bags 21, 22 are supported by the blast air supply layer 25 and the lower air bags 23, 24 having a predetermined elasticity, the upper air bags 21.
Even if the user's weight is locally added to 22,
The force is the blast air supply layer 25 and the lower air bags 23, 24.
Therefore, the "bottoming phenomenon" in the upper air bags 21, 22 does not occur at all.

Further, the blast air supply layer 25 is one plane that supports the entire upper air bags 21 and 22 from below, and moreover, the blast air supply layer 25 is in communication with each other. The air ejection hole 26 is also the upper air bag 21.
Since it is spread over the entire space between 22 and a part of the air ejection hole 26 is ejected by the user's body or the like, the drying action by the air ejection is surely performed. In other words, even if the air supply to the injection air supply layer 25 is only one place, unlike the conventional one shown in FIG. The air to be jetted is always supplied through the air supply layer 25, and if there is a bottoming phenomenon in a part of the jet air supply layer 25, the air is not jetted from the air jet holes 26 in that portion. Also, air is ejected from the air ejection hole 26 somewhere.

In particular, the shapes of the upper air bags 21, 22 and the lower air bags 23, 24 are the same as those of the floor slip prevention mat 100 according to claim 4 as the upper air bags 21, 22 and the lower air bags. It is assumed that the bags 23 and 24 are diagonal lines or a zigzag shape in which they are combined, and that the upper air bags 21 and 22 and the lower air bags 23 and 24 intersect each other when seen in a plan view. If configured, each upper air bag 21,22 lower air bag 23.2
Since the support by 4 is performed three-dimensionally rather than flatly, even if local gravity is applied to the upper air bags 21 and 22, the force is exerted via the blast air supply layer 25 on each lower side. It is dispersed by the air bags 23 and 24.

In other words, in the conventional device shown in FIG. 8 or FIG. 9, when the weight of the user is locally applied, a bottoming phenomenon occurs in the bag-shaped body 1 at that portion. However, the floor slip prevention mat 10 of the present invention
At 0, even if a local force is applied to the upper air bags 21 and 22 and the upper air bags 21 and 22 are about to be crushed, the upper air bags 21 and 22 are blown by the lower air bags 23 and 24 and the jet air supply layer 25 in the above-described state. That is to say, since the "retraction place" is prepared, the upper air bags 21, 22 are not completely crushed.

Also in the lower air bags 23 and 24,
Since the upper air bags 21 and 22 are formed in a comb-like shape and are inserted into each other, the air column of the mat body 10 is not an intervening mere flat air layer similar to the blast air supply layer 25. Since they are connected in the lateral direction on the lower surface, a large number of free spaces are positively formed in a portion between the lower air bags 23 and 24 and below the mat body 10. There is. Therefore,
Since a large number of these free spaces are present below the mat body 10 during use, the blast effect by the blast air supply layer 25 and the lower air bags 23, 24 can be surely exhibited. The bottoming phenomenon in the upper air bags 21 and 22 and the blast air supply layer 25 is reliably prevented.

As described above, also in the floor slip prevention mat 100 according to the second embodiment, the upper air bags 21 and 22 are provided.
In addition, since the bottoming phenomenon does not occur in the blast air supply layer 25, the massage action by the upper air bags 21 and 22 and the drying action by the air ejection from each air ejection hole 26 are always ensured. .

Each item is explained separately. In this case, FIG. 1 shows both Examples 1 and 2, FIGS. 2 to 4 show Example 1, and FIGS. 5 to 7 show Example 2.

(Floor slip prevention mat 100 of Embodiment 1) FIGS. 1 to 4 show a floor slip prevention mat 100 according to Embodiment 1, and in particular, FIG. 1 is a plan view thereof (a).
And a bottom view (b) of the floor displacement prevention mat 100 in which the air supply device 30 and the like are omitted and only the mat body 10 is shown. This floor slip prevention mat 100 has a flexible sheet 11 made of vinyl or the like as shown in FIG. 3 or 4, for example.
To 13 are stacked in order from the top, the mat main body 10 is formed by welding the mat main body 10 to each other at predetermined positions, and the distributor 31 connected to the mat main body 10 via the connection pipe 32. It has an air supply device 30.

The mat body 10 is first of all
The pair of the second flexible sheet 11 and 12 and the second flexible sheet 11 and 12 are welded to each other by the two upper welding zones 15a and 15b forming a closed curve to form a comb-like shape and enter each other on the upper side of the floor misalignment prevention mat 100. And two upper air bags 21 and 22 which are continuous in the lateral direction.

That is, in the mat body 10, as shown in FIGS. 3 and 5, the uppermost first flexible sheet 11 and the lower second flexible sheet 12 are arranged on the upper side. 1
The welding zone 15a and the second upper welding zone 15b are partially welded to each other, and as a result, as shown in FIG. The two upper first bladder 21 and the upper second bladder 22 which are connected to each other are formed. Each of the upper first bladder 21 and the upper second bladder 22 is filled with air and inflated, so that each of them is one continuous bag having a comb tooth shape. Is. To do so, the upper first weld zone 15a and the upper second weld zone 15b are
As shown in (a) of, a closed curve, that is, "one stroke"
It is a loop that can be done. Of course,
Even though it is called a loop, the upper first part formed by this
As described above, the air bladder 21 and the upper second air bladder 22 are comb-shaped ones that enter each other as a whole.

The upper air bladders 21 and 22 of this embodiment are alternately filled and discharged with an air supply device 30 and a distributor 31, which will be described later. In other words, the upper air bladders 21 and 22 of the present embodiment are for performing the massage action while approaching the body of the user. The upper first bladder 21 and the upper second bladder 22 in this embodiment have a diameter of about 5 cm or more. And each upper air bag 21.2
The air pressure by the air supply device 30 to be supplied into the air conditioner 2 is about 22 mmHg, and compared with the conventional air pressure of 25 to 30 mmHg shown in FIG. The air bags 21 and 22 are soft. Therefore, each of these upper air bags 2
The parts 1.22 can support the user softly and surely prevent the floor displacement of the user.

Further, in the mat body 10, as can be understood from the comparison between (a) and (b) in FIG. 1, the upper air bags 21 and 22 are constructed in a zigzag shape in which diagonal lines are formed or a combination thereof. It has been done. This is done so that the upper air bags 21, 22 of the user can be supported on a line that is longer than the height of the user, and the massage effect of the upper air bags 21, 22 can be increased. Is.

Then, as shown in FIGS. 3 and 4, on the lower surface of the upper air bags 21 and 22 configured as described above,
A planar blast air supply layer which is formed by welding the second and third flexible sheets 12 and 13 at their peripheral portions and is located on substantially the entire lower surface of the floor slip prevention mat 100. 25 is formed. And
As shown in FIG. 3, the welding zone 15a between the two upper air bags 21 and 22 is attached to the blast air supply layer 25.
The large number of air ejection holes 26 formed in the portion 15b and communicating with the blast air supply layer 25 communicate with each other. In other words, by interposing the jet air supply layer 25 that spreads over the entire lower surface of the upper air bags 21 and 22 and opening the inside of the jet air supply layer 25 upward by the air jet holes 26, a large number can be obtained. The air ejection holes 26 are spread over substantially the entire surface of the mat body 10.

In addition, the upper air bags 21 and 22 as described above
As shown in FIG. 4, each of the connection ports 17 is provided for the blast air supply layer 25 and the blast air supply layer 25, and air can be supplied from the outside through each of the connection ports 17. That is, the connection pipe 32 is connected to each connection port 17, and the distributor 31 is connected to each connection pipe 32.
Also, air is supplied through the air supply device 30.

In the floor slip prevention mat 100 according to the first embodiment, the massage effect is exerted only by the upper air bags 21, 22.
Air is of course supplied from the connection port 17 connected to. On the other hand, the blast air supply layer 25 is
Because it expands at a constant pressure and exerts elasticity,
From the connection port 17, an air supply device 30 and a distributor 31
The air is blown via the so that the inside of the jet air supply layer 25 has a predetermined pressure. Therefore, the air supply device 30 and the distributor 31 are formed by a conventionally known method / configuration so as to exhibit the above-described functions. Needless to say, the distributor 31 is not necessary if the supply device 30 itself has it.

(Floor slip prevention mat 100 of Embodiment 2) The floor slip prevention mat 100 of Embodiment 2 uses all of the constituent members of Embodiment 1 above.

The flexible sheet 11 to 1 of this Example 2 has a total of four sheets.
The point is that 4 is sequentially stacked from the top. Therefore, in the description of the second embodiment, portions that largely overlap with those described in the first embodiment are denoted by the same reference numerals as those used in the first embodiment in FIGS. 1 and 5 to 7. , Its detailed description is omitted.

FIG. 1 and FIGS. 5 to 7 show a floor displacement prevention mat 100 according to the second embodiment. In FIG. 1, a floor plan (a) of the floor displacement prevention mat 100 and an air supply device are shown. A bottom view (b) of the floor slip prevention mat 100, in which 30 and the like are omitted and only the mat body 10 is shown, is shown. The mat main body 10 mainly constituting the floor slip prevention mat 100 has a total of 4 as shown in FIG. 6 or 7, for example.
