[0001]

[Industrial applications]

 The present invention relates to a bendable mat. More specifically, the present invention relates to a foldable mat that can be folded regardless of front and back by connecting a plurality of mat units with an annular belt.

[0002]

[Prior art]

 Conventionally, a bed mat that can be folded and extended by an old person or a child by himself or a care bed that facilitates care for a bedridden old person, the one shown in FIG. 12 or FIG. 16 has been generally used. There is.

The bed mat 50 shown in FIG. 12 includes a mat 51 having a rectangular parallelepiped shape and a mat cover 52 surrounding the mat 51. As shown in FIG. 13, the mat 51 is formed with a plurality of V-shaped grooves 53, 54 at right angles to the longitudinal direction of the mat 51. Of the V-shaped grooves 53, 54, substantially the center of the mat 51 is formed. The V-shaped groove 53 formed in the portion is used only when the mat 51 is folded back to the side opposite to the V-shaped groove 53, and is formed smaller than the other V-shaped grooves 54. In order to construct a care bed or the like by actually using the bet mat 50, for example, as shown in FIG. 14, the mat 51 is folded back to the side opposite to the V-shaped groove 53 with the V-shaped groove 53, and the V-shaped groove is formed. It is necessary to bend the mat 51 to the V-shaped groove 54 side at 54 so that both sides of the V-shaped groove 54 come into contact with each other and press each other.

The bed mat 60 shown in FIG. 16 is composed of two large and small mats 61 and 62 having a rectangular parallelepiped shape and mat covers 63 and 64. Then, as shown in FIG. 17, one edge of the mat cover 63 that covers the large mat 61 and one edge of the mat cover 64 that covers the small mat 62 are sewn, and the sewn portion is turned up at the folding point 65. Is configured as. A V-shaped groove 66 is formed on the large mat 61 at right angles to the longitudinal direction of the mat 61. To actually use the bed mat 60 to construct a care bed or the like, for example, as shown in FIG. 18, two mats 61 and 62 are folded back at a folding point 65 and formed on the mat 61. It is necessary to bend the mat 61 toward the V-shaped groove 66 side by the V-shaped groove 66 so that both sides of the V-shaped groove 66 are in contact with each other and press each other.

[0005]

[Problems to be solved by the device]

 However, the conventional bed mat 50 has the following problems. By using the V-shaped groove 54 a plurality of times, the side surface of the mat 51 having the V-shaped groove 54 is deformed or the mat portion 55 on the opposite side of the V-shaped groove 54 is deformed as shown in FIG. There is also a risk that the mat 51 may be worn out and become dimples, and finally the mat 51 may be cut near the V-shaped groove 54. The same thing can happen for the V-shaped groove 53 in the substantially central portion of the mat 51. When the mat 51 is bent in the V-shaped groove 54, it is easy to fold it to the opposite side of the V-shaped groove 54, but bending to the V-shaped groove 54 side requires a force. Since the mat 51 is a single sheet, it has poor breathability. Therefore, it is possible to use a material with excellent breathability for the mat 51, but a material with excellent breathability has the disadvantage that it is weak in bending and easily deformed because the space occupies a large proportion of the material. Therefore, it is unsuitable as a material for the mat 51 that is used by folding back and forth.

Further, the conventional bed mat 60 has the following problems. Since the edge portions of the mat covers 63 and 64 are sewn together and the sewn portion is formed as the folded-back portion 65, there is little risk of cutting even if the folded-back portion 65 is used plural times. The sewing cost will increase and the work efficiency will decrease due to the increase in the number of work processes. The V-shaped groove 66 formed on the large mat 61 has the same problem as the V-shaped groove 54 of the mat 51. Although the air permeability of the bed mat 60 is better than that of the bed mat 50 by utilizing the sewing place, the bed mat 60 as a whole is insufficient.

In view of the above situation, the present invention does not damage the mat even if it is used by bending a plurality of times, requires almost no force when bending the mat, and easily bends the mat regardless of the front and back sides. The present invention aims to provide a foldable mat that can be bent and has excellent breathability.

[0008]

[Means for Solving the Problems]

 The foldable mat of the present invention includes a plurality of mat units arranged in a line so that a space is formed between adjacent mat units, at least two annular belts for connecting the plurality of mat units, and a mat cover. The mat belt unit is wound around the mat units along the row direction of the mat units from the mat unit at one end to the mat unit at the other end so as to surround each mat unit, and The upper belt portion hung along the upper surface of one mat unit is hung along the lower surface of the adjacent mat unit through the gap between the mat units, and also along the lower surface of the one mat unit. The hanging lower belt part is hung along the upper surface of the adjacent mat unit through the gap between the mat units. As has repeatedly surfaces to bridge the belt up and down alternately, characterized in that the whole mat unit multiple is covered with a mat cover.

[0009]

[Action]

 The foldable mat of the present invention comprises a plurality of mat units arranged in a line so that a gap is formed between adjacent mat units, which are joined together only by an annular belt, and the belt of each mat unit is hung. Since the passing surface is configured by alternating up and down, the folding of the flexible mat involves only the annular belt located in the gap between the mat units, so the mat unit may be damaged by multiple folding. In addition, it requires almost no force when bending the mat unit, and can be easily bent regardless of the front and back sides. Furthermore, since a large part of the space is formed between the adjacent mat units, air can smoothly flow through the space.

[0010]

【Example】

 Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows a foldable mat A which is an embodiment of the present invention. The foldable mat A is used as a care bed for the bedridden elderly and is composed of mat units 1, 2, 3, 4, annular belts 5, 6 and a mat cover 7.

The mat units 1, 2, 3, 4 are rectangular parallelepipeds whose height is smaller than their width and length, and in this embodiment, they are easy to use when assembled as a foldable mat A. In consideration of air permeability and the like, four mat units are used. The size of the mat unit is substantially the same in the mat unit 2 and the mat unit 3, and the mat unit 4 <mat unit 1 < Although the mat unit 2 is formed, the mat can be formed by using the appropriate number and size of mat units according to the application. Further, for the mat units 1, 2, 3, and 4, urethane or polyester synthetic fibers are used in this embodiment from the viewpoint of durability, elasticity and the like.

The annular belts 5 and 6 are flat belts having a rectangular cross section, and their materials are not particularly limited as long as they are durable. The belts 5 and 6 may be commercially available straps or the like as long as they do not bite into the mat units 1, 2, 3 and 4, and may be stretchable.

The mat cover 7 is a bag that is slightly larger than a bag in which the mat units 1, 2, 3 and 4 are arranged in a line so that a gap is formed between adjacent mat units. Is the same as a commercially available mat cover.

Next, a method of forming the foldable mat A using the mat units 1, 2, 3, 4, the annular belts 5, 6 and the mat cover 7 will be described. First, as shown in FIGS. 2 and 3, the mat units 1, 2, 3 and 4 are arranged so that the long sides of the adjacent mat units face each other and a gap is formed between the adjacent mat units. The original shape of the foldable mat A is arranged in a line.

Next, as shown in FIG. 3, the belt 5 is arranged along the row direction of the mat units 1, 2, 3, 4 so as to surround the leftmost mat unit 1 at one end in the row direction. The upper belt portion 5a, which is laid over and hung along the upper surface of the leftmost mat unit 1, passes through the gap between the mat unit 1 and the mat unit 2 and is hung along the lower surface of the adjacent mat unit 2. Further, the lower belt portion 5b hung along the lower surface of the leftmost mat unit 1 is hung along the upper surface of the adjacent mat unit 2 through the gap between the mat unit 1 and the mat unit 2. To be able to In the same manner, the surface around which the belt 5 is laid is alternately repeated up and down, and the belt 5 is laid around so as to surround the mat units 2 and 3, and finally, the mat unit 4 on the right end is surrounded by the belt 5. After that, both ends of the belt 5 are connected to each other by gluing or tying, and the passing of the belt 5 to the mat units 1, 2, 3, 4 is completed. In this embodiment, the belt 5 is stretched from the leftmost mat unit 1 to the rightmost mat unit 4 so as to surround each mat unit, but it is stretched from the rightmost mat unit 4 to the leftmost mat unit 1. It is also possible to hand over.

If the gap between the adjacent mat units is too large, the mat units are unstablely connected to each other and it is uncomfortable to sleep, and if it is too small, the air permeability is deteriorated. Although the size is set to about 5 mm, in practice, the size of the mat cover 7 is determined by the standard, and therefore the above-mentioned gap is necessarily determined by the size and number of mat units.

Similarly, the belt 6 is also stretched along the row direction to the other end in the row direction. Therefore, on the left side surface portion of the mat unit 1, as shown in FIG. 4, the belts 5 and 6 form a C-shape. In this embodiment, as shown in FIG. 2, the belt 5 and the belt 6 are arranged so as to be symmetrical with respect to the central axis of the original shape of the foldable mat A in the longitudinal direction, but they are not necessarily symmetrical. It doesn't have to be.

In this embodiment, the belts 5 and 6 are stretched around the mat units 1, 2, 3 and 4, and finally both ends of the belts 5 and 6 are bonded or bonded. The belt 5 is wound around the mat units 1, 2, 3 and 4, but the belts 5 and 6 are formed in an annular shape from the beginning, and the left mat unit 1 to the right mat unit are formed. It may be a method in which the mat units are bridged so as to surround each mat unit. However, in this method, it is necessary to determine the lengths of the annular belts 5 and 6 in advance, and since there is almost no margin for the annular belts 5 and 6, the annular belts 5 and 6 easily get caught in the mat unit, On the contrary, since the work efficiency may be lowered, the method of finally connecting both ends of the belts 5 and 6 by adhesion or binding as in the present embodiment is preferable.

Although the mat units can be connected to each other even if the number of belts is one, in consideration of the stability, sleeping comfort, and ease of use of the completed foldable mat A, the present embodiment can be used. It is necessary to use at least two belts 5 and 6 as described above. If the mat unit used is large, use two or more belts.

Next, a method of bending the bendable mat A in the gap portion between the mat units will be described. Here, as shown in FIG. 5A, a method of bending the mat unit 4 with respect to the mat unit 3 in the horizontal state will be described, but the same applies to other portions. First, as shown in FIG. 5B, when the mat unit 4 in a horizontal state is bent upward with respect to the mat unit 3, the upper right end portion 3a of the mat unit 3 is located at the upper left end portion 4a of the mat unit 4. And the left lower end 4b of the mat unit 4 moves away from the right lower end 3b of the mat unit 3. In this case, the belt 5 located in the gap formed between the mat unit 3 and the mat unit 4, that is, the upper belt portion 5c hung along the upper surface of the mat unit 3 is located between the mat units. When hung along the lower surface of the adjacent mat unit 4 through the gap, the length of the upper belt portion 5c in the gap portion between the mat units and the lower belt portion 5d hung along the lower surface of the mat unit 3 The length of the lower belt portion 5d in the gap portion between the mat units does not change at all when it is hung along the upper surface of the adjacent mat unit 4 through the gap between the mat units.

Further, as shown in FIG. 5C, when the mat unit 4 in the horizontal state is bent downward with respect to the mat unit 3, the lower right portion 3b of the mat unit 3 is located at the lower left of the mat unit 4. The end 4b approaches, and the upper left end 3a of the mat unit 3 moves away from the upper left end 4a of the mat unit 4. Also in this case, the lengths of the belt 5c and the belt 5d in the gap between the mat units do not change at all. That is, the mat unit 4 can be freely bent in any of the upper and lower directions. Therefore, for example, as shown in FIG. 6, a desired care bed or the like can be easily configured simply by bending each mat unit 1, 2, 3, 4 in an appropriate direction.

As described above, in the foldable mat A of the present invention, each mat unit 1, 2, 3, 4 is tied only by the two belts 5, 6, and each mat unit 1, 2, 3, Since the surfaces on which the belts 5 and 6 of 4 and 4 are bridged are alternately repeated up and down, only the belts 5 and 6 positioned in the gap between the mat units are involved in bending the bendable mat A. , The mat unit is not damaged by bending multiple times and has excellent durability. In addition, it requires almost no force when bending the mat unit, and can be easily bent regardless of the front and back sides. Further, since most of the space between the adjacent mat units is a gap, the air can smoothly flow through the gap, so that the air permeability is excellent.

Next, another embodiment of the foldable mat will be described. FIG. 7 shows a foldable mat B which is an embodiment of the present invention. The structure of this foldable mat B is substantially the same as that of the foldable mat A described above, but only the point that six mat units 11, 12, 13, 14, 15, 16 are used. Different from A case. That is, since there are many foldable portions as compared with the foldable mat A, for example, as shown in FIG. 8, folds can be made at the gap portions h, j, l, and as shown in FIG. It can be bent at k or at any gap. Therefore, using one foldable mat B, it is possible to easily form a bed having an appropriately shaped shape such as a bed for disabled persons, a bed for caring for the elderly, and a three-fold bed. In this embodiment, the number of mat units is set to six, but by increasing the number of mat units, it is possible to form beds having more shapes.

As shown in FIG. 10, the rod-shaped mat unit 21 has dimensions of width x = 80 to 140 cm, length y = 5 to 15 cm, and height z = 5 to 10 cm, as shown in FIG. By arranging a plurality of rod-shaped mat units 21 in a line, it is possible to form a foldable mat C 1 having further excellent air permeability.

As described above, by increasing the number of mat units, one foldable mat B can be made compatible with various types of beds and the like, and the application is expanded. In addition, by forming a large number of gaps and increasing air permeability, bedridden of a bedridden elderly person or the like can be effectively prevented.
