Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a foldable fold laid on the upper surface of a bed and bent by a folding mechanism of the bed.

[0002]

2. Description of the Related Art In recent years, nursing beds for the aged and sick have become widespread. As shown in FIG. 7, in such a bed B, a folding mechanism (not shown) is provided in the bed B so that the back portion can be tilted and lifted, or it corresponds to the knee of a lying person. We are making it possible to bend the part upward. Further, a tatami T is laid on the upper surface of the bed in order to give a person lying on the bed a feel of a Japanese tatami mat.

By the way, in the case where the tatami T is laid in the bed B which is bent as described above, the tatami T must also be formed so as to be bendable at a corresponding position according to the bending mechanism. In this case, as a technique for bending the tatami T, for example, a tatami proposed by the applicant of the present application is known (published in Japanese Utility Model Laid-Open No. Sho 60-187238), and this technique is used for bending. It is conceivable to construct a tatami mat corresponding to the bed B of the mold. For example, as shown in FIG. 8, a tatami mat T is provided between the toe side support single body 1 supporting the toe side from the knee of a lying person, and the toe side support single body 1 continuously provided between the knee and the waist. A crotch support unit 2 for supporting the crotch, a waist support unit 3 connected to the crotch support unit 2 for supporting the waist, and a head side support unit 4 connected to the waist support unit 3 for supporting the head side. In each bending portion, a sheet-like connection having a bending portion 5 on the surface side on which the angle (θ) formed by each bending of the support single bodies 1, 2, 3, 4 becomes smaller due to these bending. The supporting members 1, 2, 3 and 4 are continuously provided with the installation members, and the tatami mat 6 is covered on the supporting units 1, 2, 3, and 4.

[0004]

However, in the tatami formed so as to be bendable, the bent portion 5 of the portion corresponding to the knee is bent convexly at the time of bending, A recess 7 that opens upward is formed between the end surface of the toe-side support single body 1 and the end surface of the crotch support single body 2, and the tatami mat 6 is loosened by a distance corresponding to the distance between the recesses 7. Since it must be kept, each support unit 1, 2, 3,
There was a problem that the tatami mat 6 was loose when the 4 was returned to the original flat shape. Further, in the process of returning the support single bodies 1 and 2 to the original flat state, the tatami mat 6 is caught in the recess 7 and is pinched, and the tatami mat 6 is not damaged or is not sufficiently flat. There was a problem such as loss of sex.

The present invention has been made in view of the above problems, and a portion corresponding to the knees of a reclining person is provided so that the tatami mat does not get caught and the tatami mat is not pinched. It is an object of the present invention to provide a foldable tatami that can be bent upward.

[0006]

In order to achieve such an object, the foldable tatami of the present invention supports a person lying down and is also provided with a plurality of support units connected in a foldable manner. A foldable tatami mat which is laid on the upper surface of a bed and is folded by a folding mechanism of the bed, which is provided with a tatami mat which is covered by a supporting unit, so that a portion corresponding to a knee of a lying person can be bent upwardly. So, as the above support alone,
At least a foot-side support unit that supports the toe side from the knee of a lying person, a crotch support unit that is connected to the toe-side support unit and supports a crotch between the knee and the waist, and the crotch support A waist support unit for supporting the waist, which is continuously provided as a single unit, and each support unit is continuously provided with a connecting member having a bent portion on the tatami side of the connecting end face, and the foot side. The continuous end faces of the support single body and the crotch support single body are each formed as an inclined surface that is inclined in a direction in which they are separated from each other from the front surface side to the back surface side.

As a result, this folding tatami mat is laid on the upper surface of the bed for use, and is bent by the folding mechanism of the bed at a suitable time. At this time, the knee of the person lying down is used. When the part corresponding to is bent upwardly, the toe side support unit and the crotch support unit are bent upwardly, and the crotch support unit is bent downwardly with respect to the waist support unit.
In this case, the toe side support unit and the crotch support unit are bent at the folding portion on the tatami side of the connecting member connecting them, but the connecting end faces of the toe side support unit and the crotch support unit are Since the inclined surfaces are formed so as to be inclined in the direction away from each other from the front surface side to the back surface side, the inclined surfaces do not interfere with each other and smoothly bend. That is,
Even if the bent portion between the foot-side support unit and the crotch support unit is simply provided on the tatami side, the continuous end faces of the foot-side support unit and the crotch support unit are formed as right-angled surfaces perpendicular to the front and back surfaces. If so, it becomes impossible to bend them by interfering with each other, but the present invention is devised so as to prevent such interference.

On the other hand, when each support unit is returned to its original flat shape by the bed bending mechanism, in the toe side support unit and the crotch support unit, the bending is performed at the folding portion on the tatami side of the connecting member. Since this is performed, there is no formation of a recess that opens upward between the end surface of the foot-side support single body and the end surface of the crotch support single body.Therefore, the tatami mat enters the recess and is sandwiched or pinched. It is possible to prevent the tatami mat from being damaged. And
The tatami mat should be relatively taut without any slack because there is no recess formed between the end surface of the foot-side support unit and the crotch support unit when opening. It is possible to secure the flatness of the tatami mat in a normal state without being loosened.

Further, if necessary, the continuous end faces of the support single bodies other than the continuous end faces of the toe side support single body and the crotch support single body are formed as right-angled surfaces perpendicular to the front surface and the back surface, respectively. I am trying. Processing is easy, and support is ensured in a flat state. Further, if necessary, the connecting member,
A belt-shaped front side fastening band attached across the front side end portions of the adjacent support single bodies, and a continuous end face and a back side end portion of the adjacent support single body that are sewn along the longitudinal center of the front side fastening band. And a belt-shaped backside fastening band which is attached to extend over. Since the fastening bands are attached to the front and back, the connection strength can be increased.

Furthermore, if necessary, the stitching line between the front side fastening band and the back side fastening band of the connecting member for continuously connecting the above-mentioned toe side support unit and crotch support unit is made into one line. At this part, the tatami mat is bent upwardly, so a force tends to act on the tatami mat in the pulling direction, but since the bent part of the connecting member is sewn in one line, the bend is relatively sharp. Becomes
Therefore, even if the tatami mat has no slack, it is surely bent.
In addition, if necessary, a suture line between the front side fastening band and the back side fastening band of the connecting member that continuously connects the connecting end faces of the supporting units other than the connecting end faces of the toe side supporting unit and the crotch supporting unit. Is made up of two or more articles. At this part, the tatami mat is bent downwardly, so a force tends to act on the tatami mat in the compression direction, but since the bent part of the connecting member is sewn with two threads, the bend is relatively obtuse. Therefore, the tatami mat is surely bent and the tatami mat is surely supported.

Further, if necessary, the front side fastening band and the back side fastening band of the above-mentioned connecting member are fixed to each supporting unit by a fastening pin. Since it is stopped with a pin, the attachment is secure and the connection strength is improved. Furthermore, if necessary, between the front side fastening band and the support single body of the connecting member, and between the back side fastening band and the support single body of the connecting member,
It is configured to be attached across the adhesive tape. Since it is fixed with adhesive tape, the attachment is secure and the connection strength is improved. In addition, each of the above-described support units is configured to include a core, a plate attached above and below the core, and a sheet that covers the plate, if necessary. Since it has a board,
It becomes stronger against bending stress and improves the support strength when the tatami is bent. Further, the head support unit is provided so as to be connected to the waist support unit and support the head side. It can also be used on the back and head.

The head-side supporting unit 4 can bend and support the back and head of a reclining person with respect to the waist.

Each of the supporting units 1, 2, 3 and 4 covers a lightweight core formed by compression-molding wood chips or wood chips, plates 11 and 11 such as veneers attached above and below the core 10, and an upper plate 11. The cushion sheet 12 is made of a non-woven fabric, and the protective sheet 13 covers the lower plate 11 and has a resin-coated surface. Since the plate 11 is provided, it becomes strong against bending stress, and the support strength when the tatami T is bent can be improved. Further, as shown in FIG.
Through holes 14 are appropriately provided in the. Breathability is secured.

Further, the continuous end faces of the toe side support single body 1 and the crotch support single body 2 are each formed as an inclined surface 15 which is inclined in the direction away from each other from the front surface side to the back surface side. Further, the end faces of the supporting units other than the connecting end faces of the toe side supporting unit 1 and the crotch supporting unit 2, that is, the crotch supporting unit 2
Further, the continuous end surface of the waist support single body 3 and the continuous end surface of the waist support single body 3 and the head side support single body 4 are respectively formed as right-angled surfaces 16 perpendicular to the front surface and the back surface.

Further, each supporting unit 1, 2, 3, 4
Are connected by a connecting member 20 having a bent portion 21 on the side of the tatami mat 6 of these connecting end faces. The connecting member 20 includes a belt-shaped front side fastening band 22 attached to the front side end portion of an adjacent support single body, and a sewn seam along the center of the front side fastening band 22 in the longitudinal direction. It is configured to include a belt-shaped back side fastening band 23 that is attached across the continuous end surface and the back side end portion. Further, as shown in FIG. 2, the suture line H between the front side fastening band 22 and the back side fastening band 23 of the connecting member 20 that continuously connects the toe side support single body 1 and the crotch support single body 2 is one line. . Further, a continuous member 2 for continuously connecting continuous end faces of the single support members other than the continuous end faces of the toe side support single body 1 and the crotch support single body 2.
The stitching line H between the front side fastening band 22 and the back side fastening band 23 of 0 is two.

Furthermore, the front fastening band 22 of the connecting member 20.
The back fastening band 23 is fastened to each of the supporting units 1, 2, 3, 4 by a U-shaped fastening pin 30. In addition, an adhesive tape 31 is attached so as to straddle between the front side fastening band 22 of the connecting member 20 and the support single body, and between the back side fastening band 23 of the connecting member 20 and the support single body. There is.

Therefore, when manufacturing the folding tatami mat T according to this embodiment, as shown in FIG. 2, each supporting unit 1, 2, 3, 4 is adjacent to each supporting unit 1, 2, 3, 4. The end faces of No. 4 are butted against each other and connected by the connecting member 20. Figure 5
As shown in FIG. 5, in the case of the toe side support single body 1 and the crotch support single body 2, first, as shown in FIGS. Using the connecting member 20 having the line H, the front side fastening band 22 is attached across the front side end portions of the adjacent support single units 1 and 2, and the back side fastening band 23 is attached to the adjacent support single unit. It adheres across the continuous end face (slope 15) of 1 and 2, and the back side edge part. Since the fastening bands 22 and 23 are attached to the front and back, the connection strength can be increased. Then, as shown in FIG. 5B, the front side fastening band 22 and the back side fastening band 23 are fastened to the respective support units 1 and 2 with the fastening pin 30. In this case, since it is stopped by the stop pin 30, the attachment is made reliable and the strength is improved.
Next, as shown in FIG. 5C, between the front side fastening band 22 of the connecting member 20 and the supporting units 1 and 2, and the connecting member 2
An adhesive tape 31 is attached across the back side fastening band 23 of 0 and the support single units 1 and 2. In this case, since the adhesive tape 31 is used for the fixing, the attachment can be ensured and the strength can be improved.

Further, as shown in FIG. 6, in the case of the crotch support single body 2, the waist support single body 3, the waist support single body 3 and the head side support single body 4, similarly, first, as shown in FIGS. As shown, these connecting end faces are opposed to each other, and this time, using the connecting member 20 sewn with two threads, this front side fastening band 22 is attached to the front side end portions of the adjacent supporting units 2, 3, and 4. The back side fastening band 23 is attached across the continuous end face (right-angled face 16) and the back side end of the adjacent support units 2, 3, and 4. Since the fastening bands 22 and 23 are attached to the front and back, the connection strength can be increased. Then, as shown in FIG. 6 (b), the front side fastening band 22 and the back side fastening band 23 are fastened to the respective support units 2, 3, 4 by the fastening pin 30. In this case, since it is stopped by the stop pin 30, the attachment is made reliable and the strength is improved. Next, as shown in FIG.
The front fastening band 22 of the connecting member 20 and the supporting unit 2, 3, 4
And the backside fastening band 23 of the connecting member 20 and the support units 2, 3 and 4 are attached by straddling the adhesive tape 31. In this case, since the adhesive tape 31 is used for the fixing, the attachment can be ensured and the strength can be improved.

Then, as shown in FIG. 5 (d) and FIG. 6 (d), the tatami mat 6 is provided with the supporting units 1, 2, 3, 3 connected in series.
4 is coated. In this case, it should be relatively taut without any slack. Then, the edge portion of the tatami mat 6 is folded and processed, and an edge 8 (FIG. 1) is attached if necessary. At the edge of the tatami mat 6 that corresponds to the bent portion 21, make a cut in the edge of the tatami mat 6 and fold it on the back side of the support unit, attach it to the support unit using tape or the like, and bend between the end faces. Be able to separate from time to time.

The folding tatami T produced in this way
1 is laid on the upper surface of the bed B as shown in FIG. 1 for use. Then, it is bent and used by the bending mechanism of the bed B at a proper time. First, by bending the toe side support single body 1 and the crotch support single body 2, it is possible to make the part corresponding to the knee of the person lying down to be convex upward. In this case, as shown in FIG. 3, the toe side support single body 1 and the crotch support single body 2 are bent at the bent portion 21 on the tatami mat 6 side of the connecting member 20 that connects them, Side support single unit 1 and crotch support single unit 2
Since the continuous end surfaces of the inclined surfaces 15 are inclined in the direction in which they are separated from each other from the front surface side to the back surface side, the inclined surfaces 15 do not interfere with each other and can be smoothly bent. I will do it. Further, in this case, since the tatami mat 6 is bent upwardly at this portion, a force tends to act on the tatami mat 6 in the pulling direction, but the bent part 21 of the connecting member 20 is sewn in one line. The bend is relatively sharp,
Therefore, even if the tatami mat 6 has no slack, the tatami mat 6 is surely bent.

At this time, as shown in FIG. 4, the crotch support single body 2 and the waist support single body 3 are also bent, but the continuous end faces of the crotch support single body 2 and the waist support single body 3 are respectively Since they are separated from each other, they can be smoothly bent. In this case, since the tatami mat 6 is bent downwardly at this portion, a force tends to act on the tatami mat 6 in the compression direction.
Since 1 is sewn with two threads, the bending is relatively obtuse, so that the tatami mat 6 is surely bent and the tatami mat 6 is surely supported.

Further, as shown in FIG. 1, by bending the waist support single body 3 and the head side support single body 4, the back and head of a reclining person can be tilted and supported with respect to the waist. In this case, as shown in FIG. 4, the continuous end faces of the waist support single body 3 and the head side support single body 4 are
Since they are separated from each other, they bend smoothly. Further, in this case, since the continuous member 20 sewn with two threads is used in this portion, the bending is relatively obtuse,
Since the tatami mat 6 is bent downwardly convexly, the tatami mat 6 is surely bent even if the tatami mat 6 is not loose. Also, since the two stitches are used for stitching, the tatami mat 6 which is convex downward is reliably supported.

Next, the case where the supporting units 1, 2, 3, 4 are returned to their original plane shapes by the folding mechanism of the bed B will be described. First, in the toe side support single body 1 and the crotch support single body 2, as shown in FIG. 3, the toe side support single body 1 and the crotch support single body 2 are folded on the tatami mat 6 side of the connecting member 20 that connects them. Although the bending is performed at the bending portion 21, the continuous end faces of the toe side support single body 1 and the crotch support single body 2 are separated from each other, so that the bending is smoothly performed. In this case, the connecting member 2
Since the bending is performed at the bent portion 21 on the tatami mat 6 side of 0, between the end surface of the toe side support single body 1 and the end surface of the crotch support single body 2,
There is no open recess on the top, so
The tatami mat 6 goes into the recess and is sandwiched, or it is sandwiched and the tatami mat 6
The situation that damages the body is prevented.

At this time, the crotch support single body 2 and the waist support single body 3 are also folded and returned to the original state, but as shown in FIG. 4, they are folded at the bent portion 21 on the tatami mat 6 side of the connecting member 20. Since the bending is performed, there is no formation of an upwardly opening recess between the end surface of the crotch support single body 2 and the end surface of the waist support single body 3, and therefore, the tatami mat 6 is inserted into the recess and sandwiched. It is possible to prevent the situation where the tatami mat 6 is pinched or damaged by being pinched.

In the waist supporting unit 3 and the head supporting unit 4, as shown in FIG. 4, the waist supporting unit 3 and the head supporting unit 4 are located on the tatami mat 6 side of the connecting member 20 connecting them. Although the bending is performed at the bending portion 21, since the bending is performed at the bending portion 21 on the tatami-mat 6 side of the connecting member 20, the bending is performed between the end surface of the crotch support single body 2 and the end surface of the waist support single body 3. Since there is no recess formed on the upper side of the tatami mat, the tatami mat 6 is prevented from being caught in the recess and being pinched, or the tatami mat 6 being damaged by being pinched.

As shown in FIG. 4, the tatami mat 6 is placed in a state where the supporting units 2, 3 and 4 are positioned in a plane.
Is relatively tight without any slack because there is no recess formed between the end surface of the toe side support single body 1 and the crotch support single body 2 when bending. Since the tatami mat 6 does not get loose, the flatness in the normal state is secured.

[0028]

As described above, according to the folding tatami of the present invention, each support unit is continuously connected by the connecting member having the bent portion on the tatami side of these connecting end faces, and the foot side support is provided. Since the continuous end faces of the single body and the crotch support single body are formed to be inclined surfaces in a direction in which they are separated from each other from the front surface side to the back surface side, the toe side support single body and the crotch support single body are projected upward. When bending the toe side support unit and the crotch support unit, the toe side support unit and the crotch support unit are bent at the bending portion on the tatami side of the connecting member that connects them. Since the installation end faces are formed as inclined faces that are inclined in the direction away from each other from the front surface side to the back surface side, the inclined surfaces can be smoothly bent without interfering with each other. . On the other hand, when returning each support unit to its original flat shape, the toe side support unit and the crotch support unit are bent at the folding portion on the tatami side of the connecting member. There is no recess that opens upward between the end surface of the crotch support and the end surface of the crotch support unit.Therefore, the tatami mat may enter the recess and be pinched, or it may be pinched and damage the tatami mat. It can be prevented. Therefore, the tatami mat can be provided so as to be relatively taut without slack, and the tatami mat can be kept flat in a normal state without being loosened.

Further, when the continuous end faces of the support single bodies other than the continuous end faces of the toe side support single body and the crotch support single body are formed as right-angled surfaces perpendicular to the front surface and the back surface, respectively, the processing is It is easy and can be surely supported in a flat state. Further, when the connecting member is configured to include the front side fastening band and the band-shaped back side fastening band sewn to the front side fastening band, the fastening bands are attached to the front and back sides of the support unit, so that the connecting strength is increased. Can be higher. Furthermore, when the front side fastening band and the back side fastening band of the connecting member that continuously connects the toe side support unit and the crotch support unit are made to have a single stitch line, the tatami mat is convex upward at this portion. Because of the bending, a force tends to act on the tatami mat in the pulling direction, but since the bent part of the connecting member is sewn with one line, the bend becomes a relatively sharp angle, so the tatami mat has no slack. However, it can be surely bent.

Further, two suture lines are formed between the front side fastening band and the back side fastening band of the connecting member connecting the connecting end faces of the supporting units other than the connecting end faces of the toe side supporting unit and the crotch supporting unit. In the above case, since the tatami mat is bent downward in this area, a force tends to act on the tatami mat in the compression direction, but since the bent part of the connecting member is sewn with two threads, Since the bend is relatively obtuse, the tatami mat can be reliably bent and the tatami mat can be reliably supported.

Further, when the front side fastening band and the back side fastening band of the connecting member are fastened to each supporting unit with a fastening pin, they are fastened with a pin, so that the attachment is ensured and the connection strength is improved. You can Furthermore, in the case where the adhesive tape is attached across the front side fastening band of the connecting member and the support single body, and between the back side fastening band of the connecting member and the support single body,
Since it is fixed with an adhesive tape, the attachment can be secured and the connection strength can be improved. In addition, when each supporting unit is configured to include a core, plates attached above and below the core, and a sheet that covers the plate, since the plates are provided, bending strength is increased and tatami mats are provided. The support strength at the time of bending can be improved. Further, in the case where the head-side support unit that is connected to the waist support unit and supports the head side is provided, it becomes possible to cope with the inclination of the back and the head side.
