JP-A-11-239591 JP 2001-54539 A

  As a result of further research and examination based on the proposed technique, the present invention has been found to have the following problems.

That is, in Japanese Patent Laid-Open No. 2001-54539, when the backrest portion is tilted upward by the seesaw mechanism, the central buttocks holding portion sinks downward, so it is convenient to sufficiently stabilize the patient's body position during defecation. In other cases, such as eating and reading, the buttocks subsided and became a cramped posture and could not take a more natural and comfortable posture for a long time.
In addition, when the seat for holding the buttock when the backrest is inclined or the toilet device is removed for maintenance, there is a serious problem that the buttock may get stuck in the hole.
In addition, there has been a demand for a more relaxed posture because the knees cannot be flexed and lifted and raised and lowered freely while the legs are moving or inclined on the mat.

In addition, the mattress is also required to be improved so that it can be opened and closed easily and reliably without excessive pulling or unnatural wrinkles when using slanted defecation.
Furthermore, there has been a demand for a more convenient thing for the caregiver to transfer the patient from the wheelchair to the bed, and for the ease of work during the use and after the defecation.

  The present invention solves these problems and has been improved in many ways. The purpose of the present invention is to ensure sufficient safety and more stably regulate the patient's posture in an easy posture. Defecation can be performed, and even when the backrest is tilted for a long time other than during defecation, the knee can be bent and stretched to take a more natural and comfortable posture. Moreover, it is intended to provide a treatment bed that is more convenient for the caregiver to transfer the patient to the bed or to facilitate the work in the cleaning work after defecation.

Means to solve the problem

  In order to achieve the above object, in the treatment bed of the present invention, the bed receiving plate or the mat integrated with the floor receiving plate is placed on the patient's waist at the center of the lower edge of the backrest portion for receiving the upper body of the patient. The back and back part of the reverse convex character shape that is integrated on the same plane by projecting the central collar part of the rectangle of the width and length that can be placed, and the rectangle that is the same width as the central collar part and parallel to the end in a straight line The center leg resting part, the left leg outer part and the right leg outer part that occupy both sides of the leg are separated in a straight line from the lower edge to the end of the back part in the shape of a letter H. Rotate the backrest using the lower edge excluding the support as a support shaft and lock it at a predetermined inclination angle, and arbitrarily change the inclination angle and repeat the inclination change and restoration without moving the patient Seesaw-type tilting restoration operation hand When the backrest part is tilted to the maximum, the line connecting the lower end of the center buttock, which is the lower part of the backrest part, and the end face of the backrest part of the central footrest part is at least substantially perpendicular to the backrest part. Provide a means for sliding the central footrest in the direction of the end of the bed, and when the backrest is tilted and the central buttocks sink down and incline, the forward flexion that is part of the central buttocks is at least inclined to the backrest In addition to refracting parallel to the support shaft at a position on the lower end side from the support shaft, a means for holding the refraction state is provided.

  In addition, it is located below the floor of the bed and faces the inclined backrest corresponding to the bottom of the rectangular hole where the patient's buttocks fit into the center of the bed that appears when the reverse convex character backrest is tilted. And providing a defecation device having an inclined toilet seat that is substantially perpendicular.

  Another object of the present invention is to provide means for refracting and restoring at least a part of the sliding center footrest in the direction perpendicular to the bed axis in order to refract and raise and lower the patient's legs and knees.

  And it is good to provide the means which raises / lowers the whole mat | matte integrated with the floor (litter) receiving plate of the bed holding a patient's upper body and lower body, or a floor receiving plate.

  In addition, with the mat mated to the mat that is integrated with the floor support plate of the bed covering the entire mat, cross the line with a straight line at the tip of the back of the reverse convex letter shape. At the four corners or edges of each divided floor covering, means for attaching to each mat is provided with a belt-like elastic material, and at the position where a margin is provided along the lower edge of the floor covering on the upper edge of the floor covering. A belt-shaped elastic material is attached to the fabric while gathering it in a state where it is stretched in the direction perpendicular to the bed axis in a range exceeding the width of the convex part at the center of the bed, and means for fixing both side ends near both side edges of the bed. At the same time, a pair of belt-like elastic materials are symmetrically placed on the bed center axis and the convex part of the backrest part is sandwiched between the upper leg of the backrest part and extended to the upper edge of the backrest part. Preferably a tip provided with a sheeting having a means for fixing to the floor receiving plate.

The invention's effect

  The most important thing is that the patient who does not move does not need a nursing hand and can wake up and defecate, and the backrest can be tilted and restored in order to lock it at a predetermined angle while always holding the patient's weight. By adopting a seesaw mechanism on the backrest of the reverse convex character shape that can be easily done, the patient can fit the toilet seat in the bed opening without moving from the inclined backrest, so that the patient in the bed at the time of defecation The posture can be reliably stabilized, and it can be used comfortably for a long time without getting tired even in an inclined backrest posture at times other than defecation such as eating or reading. Moreover, because of its simple structure, it is safe, easy to use, and inexpensive to manufacture.

  By providing a defecation device having an inclined toilet seat that is substantially perpendicular to the inclined backrest portion, it is possible to defecate comfortably and comfortably in the most natural and comfortable posture.

  By providing a means to refract and restore at least a part of the sliding center footrest in the direction perpendicular to the bed heel, the patient's legs and knees are refracted and lifted to take a more stable and relaxed posture. be able to.

  By using a bed floor or a mat that is integrated with the floor support, the caregiver can easily perform care work for the patient and transfer the patient to the bed. The cleaning and maintenance of the defecation device 9 are facilitated.

  A means for fixing both sides of the bed near both ends of the bed, with a band-shaped elastic material attached to the fabric while gathering it in a state of stretching in the direction perpendicular to the bed axis in the range exceeding the width of the convex part at the center of the backrest In addition, a pair of belt-like elastic materials are symmetrically placed on the bed center axis and the convex part of the backrest part is sandwiched between the lower limbs of the mattress and extended to the upper edge of the backrest part while expanding at least beyond parallel. By making it possible, without removing the mattress during defecation, the mattress can be easily opened from the center without obstruction, and after defecation, it can be smoothly closed and repeatedly restored. Moreover, the flooring can be always used cleanly and comfortably without unnatural pulling, loosening, and unnatural wrinkles.

  This was realized mainly by using a seesaw-like tilt restoring operation means for the backrest with a convex part, a mat sliding means, a defecation device with an inclined toilet seat, and the like.

Embodiments of the present invention will be described with reference to the drawings based on examples.
FIG. 1 is a schematic mechanism diagram showing a configuration of an embodiment of the present invention, and is a diagram showing a state of a bed when a backrest portion is inclined. FIG. 2 is a perspective view showing a state of a normal bed in which the inclination of the backrest portion of FIG. 1 is returned to a flat surface.
1 and 2, the upper surface of the bed is a rectangular center with a width and length that allows the patient's waist to be placed at the center of the lower edge of the backrest portion where the floor support and mat are integrated to receive the upper body of the patient. A reverse-convex character-shaped backrest portion 1 that is integrated on the same plane by projecting the collar portion 11, a rectangular central footrest portion 21 that is the same width as the central collar portion 11 and that is divided by a straight line to the end, and both sides thereof The left foot outer part 22 and the right foot outer part 23 occupying the upper part of the backrest 1 are straightly divided into H letters from the base to the end of the central heel part 11 of the backrest part 1.

  Then, as a seesaw-like tilt restoring operation means having a pivot 3 for raising the upper body as a support shaft 3, the cylinder telescopic arm can be stopped at a free angle and can be locked at the final limit (angle) position. 4 is provided from the lower side of the bed to the backrest part 1, and a slider rail is provided at a slide abutting part between the central footrest part 21, the left footrest part 22, and the right footrest part 23 as a means for the central footrest part 21 to slide toward the end of the bed. 20 is provided, and a cylinder telescopic arm 4b which can be stopped at a free position between any predetermined positions as a slide restoring operation means and can be locked at the final limit position is provided on the back of the floor board, and the tip of the arm is provided. It connects with the front-end | tip of the center footrest part 21. FIG.

  In this case, the tilting restoring operation means of the backrest part and the power for sliding the footrest part 21 are not necessarily limited to the embodiment, and a separate power driving device (not shown) such as a pantograph system, a rack or pinion motor, etc. Or the like, it can also be moved through the necessary power transmission devices such as various links, rollers and belts in association with the movement of the backrest.

Then, when the backrest 1 is raised and tilted, the central collar 11 sinks downward, and the canvas sheet is placed on the straight bridge between the bottom end of the tilted central collar 11 and the edge of the butted portion of the central footrest 21. 5 is provided and both ends are fixed to the respective end faces. The canvas sheet 5 is formed of a tough cloth (canvas) having a straight bridging length with a width of the central collar 11 and having a circular opening in the center. In this case, it is necessary that the center of gravity of the patient be on the upper surface of the central heel part 11 that is the convex part of the backrest part 1, and therefore, the inclination angle of the backrest part 1 is limited as much as possible so that recumbency and inclination can be repeatedly restored. And the cylinder telescopic arm 4 is adjusted so as to be locked at a predetermined angle.
When the canvas sheet 5 is provided on the straight bridge as described above, a general portable toilet is partially crafted and used without using the special defecation device 9 shown below, and the opening at the center of the canvas sheet 5 is used. It is also possible to defecate from the department.

Further, the mating surface is joined by a hinge 115 so that the central anchor 11 can be bent and stretched by dividing the base fixing part 111 and the forward bending / extending part 112 into a length of about 4: 6 in the front-rear direction (perpendicular to the long axis of the bed). In addition, when the backrest 1 is raised and tilted, the central collar 11 sinks downward, and a metal frame-shaped stay 55 that holds the forward bending part 112 of the tilted central collar 11 from the lower surface is provided. The stay 55 is rotated about the holding support shaft 57 by a handle 58 connected to the upper side, and falls to the rear of the backrest portion 1 except when the front bending portion 112 which is a part of the central collar portion 11 is held. I try to come off. In order to make this operation smooth, a weight 56 is attached to the stay 55 as a balance material in the direction opposite to the holding portion. The method of achieving this balance is not limited to the embodiment, and may be pulled back with, for example, a spring or the like.
In addition, in order that the front-end | tip of the center collar part 11 of the backrest part 1 may not interfere at the time of tilting, it is good to open a little between the contact end surfaces with the center footrest part 21, and to make a corner round.

3 is a schematic mechanism diagram showing a bed state during defecation in which the canvas sheet 5 with holes in FIG. 1 is eliminated and a defecation device having an inclined toilet seat is provided at that position, and FIG. 4 is a perspective view showing the state of FIG. FIG. 5 is a view showing the posture of the patient during defecation in FIGS. 3 and 4. FIG. 6 is a perspective view showing a tilted backrest portion in a shallow sitting state in a relaxed posture other than during defecation in the embodiment of the present invention, and FIG. 7 is a view showing the posture of the patient in FIG. .
4 and 6 do not show the tilting drive means for the backrest part and the holding means for the forward bending part of the central collar part.

  As shown in FIG. 3 and FIG. 4, the backrest 1 tilted by about 45 degrees corresponding to the bottom of a rectangular hole H where the patient's buttocks fit into the center of the bed that appears when the inverted convex character-shaped backrest 1 is tilted. A toilet bowl body 91 having a tilted toilet seat 92 that forms a substantially right angle and a toilet receiver 93 having a pull-out handle 94 is provided, and a guide weight bar 96 is attached to the front lower end so as to cover the upper side of the tilted toilet seat 92. A sheet-like shutter-type toilet lid 95 is provided. By connecting the upper end of the toilet lid 95 to the bottom surface of the central footrest portion 21 that slides, when the central footrest portion 21 is slid downward, the toilet lid 95 is lifted up and opened, and the lower end as it slides upward again. The toilet lid 95 is closed while sliding down along the inclined toilet seat 92 by the weight of the guide weight rod 96.

  As a result, as shown in FIG. 5, the patient does not need to open and close the toilet lid 95, and the buttocks are held by the backrest 1 and the inclined toilet seat 92 from both the front and rear sides. It can be used in a more comfortable posture (can be defecate).

Further, as shown in FIGS. 6 and 7 in a shallow sitting state in which the posture is relaxed other than during defecation, the root fixing portion 111 and the forward bending / extending portion 112 are arranged with the central heel portion 11 back and forth (perpendicular to the long axis of the bed). Is divided into lengths of about 4: 6 so that it can bend and stretch, so that the patient's buttocks are sufficiently held from below by the front bending and stretching portion 112.
Therefore, as shown in FIG. 7, the patient only has to tilt the handle 58 forward (foot) before tilting the backrest 1 or sliding the center footrest 21, and this posture is suitable for eating and reading It can be used for various purposes such as in a normal place of life, and as if sitting on a shallow depression, a stable relief can be obtained.

  In addition, since it supplements in this case, since the movement distance which makes the center footrest part 21 slide is small, naturally the toilet bowl lid 95 which interlock | cooperates is fully closed, without opening a little. In other words, the length of the toilet lid 95 is made to have a margin with the guide weight rod 96 in order to achieve this.

FIG. 8 is a perspective view of the defecation device according to the embodiment of the present invention with the toilet lid open.
As shown in FIG. 8, the defecation device 9 includes a toilet body 91 of a trapezoidal outer box having an inclined opening of about 40 degrees by cutting out one corner of a rectangular box as a main storage means. A toilet receiver 93 with a pull-out handle 94 that fits in the lower part of the inclined opening of the toilet body 91 is provided, and the bottom of the toilet receiver 93 is located at both ends of the drawer so that it can be easily cleaned after the flight. A semicircular curved surface from the center to the center. Then, an inclined toilet seat 92 having a cushioning property is attached to the inclined opening of the toilet body 91 in accordance with the inclined opening. Further, a cloth-like shutter-type toilet cover 95 is provided so as to cover the inclined toilet seat 92, and the upper end of the toilet cover 95 is fixed to a predetermined position on the bottom surface of the central footrest portion 21 (not shown), and the other lower end A metal guide weight rod 96 is attached. In such a case, the toilet lid 95 is automatically opened and closed because it slides along the inclined toilet seat 92 according to the movement of the sliding center footrest portion 21. As a result, it is possible to improve convenience and save power.

  It is also conceivable that the opening and closing of the toilet lid 95 is performed independently without being related to the sliding operation of the central footrest portion 21. For example, there is a method of operating an electric shutter with a unique button switch. Furthermore, it is conceivable to provide a toilet lid 95 below or inside the inclined toilet seat 92.

Furthermore, in order to make the defecation device 9 to be a local washing type after defecation, although not shown in detail, a water tank, a pressure pump and a dryer are accommodated in a space with the toilet receiver 93 inside the toilet body 91 box, and the inclined toilet seat 92 By providing the flush water outlet W at the upper part in the toilet bowl and providing the drying treatment dryer warm air outlet D on the side or on the side, it is possible to carry out with simple and inexpensive means.
As shown in FIG. 8, the dryer warm air outlet D is eccentric from the center, or is provided on the outermost side of the inner wall and is directed toward the peripheral wall of the toilet body 91. The warm air is moderately heated from the local area. Preferably dried. And the upper surface and / or the back surface of the toilet bowl body 91 can be opened, facilitating maintenance.

FIG. 9 is a perspective view showing an inclined state of the backrest portion provided with the knee bending lifting device of the present invention.
In this way, when it is desired to further relax in a state where the backrest portion is inclined, it may be easier to feel comfort when the leg is raised slightly and the knee is appropriately refracted.

FIG. 10 is a schematic mechanism diagram showing the knee refraction lifting device of the present invention. (A) is a side view of the main part, (b) is a view taken in the direction of arrow X in (a).
As shown in FIG. 10, first, the center footrest portion floor receiving plate 70 that receives the mat for the center footrest portion 21 is divided in the vicinity of 30% on the head side, and indicated by an imaginary line (two-dot chain line). The floor receiving plate hinge 70a is attached so that the divided portion is raised up and down. Then, the center footrest floor receiving plate 70 is supported on the tip end top edge of the center footrest section floor receiving plate 70 and the head end front end edge of the slide frame 72 of the center footrest section 21 with the tip upper surface edge as a support shaft. It connects with the floor receiving plate hinge 70b so that it may rotate and raise. Then, an H-shaped floor support plate lifting arm 73 connected to the lower surface of the slide frame 72 and connected to the center of the frame width inside by a bridge 74 is provided. The drive rollers 75 are attached to the left and right. The floor receiving plate elevating arm 73 is attached by an elevating arm hinge 76 so as to operate the seesaw lever on the inside of the slide frame 72 at some foot side from the center. The drive roller 75 moves along a guide rail 78 attached to the bed side edge frame 71 which is a fixed frame, along a mountain-shaped cam plate 79 projecting in the center on the integral extension line, and the drive roller 75 is moved to the cam plate 79. The driven rollers 77 on the left and right ends of the opposite side (upper side) of the floor support plate lifting arm 73 are lifted like a seesaw while the head side rear surface of the center footrest floor support plate 70 is Since it rotates, as shown by the imaginary line (two-dot chain line) in FIG. 10 (a), the center footrest portion floor receiving plate 70 rises in a mountain shape.

As a result, as shown in FIG. 11, after the handle 58 is tilted forward (foot) in advance, the central footrest portion 21 is slid about 10 cm, and at the same time, the drive roller 75 of the arm 73 becomes the most protruding portion of the cam plate 79. Therefore, the knee also rises up to about 10cm. Further, when the center footrest portion 21 is further slid, the drive roller 75 falls along the inclination angle of the cam plate 79 and becomes horizontal. Therefore, the patient can raise his knees, bend and stretch properly, maintain a more stable and comfortable posture, and bend and stretch and will not get tired even if sitting for a long time .
With the above-described structure, even in a narrow space under the bed mat, the central footrest portion floor receiving plate 70 is raised in a mountain shape so that the knee can be raised and lowered.
It should be noted that the knee refraction raising and lowering device is not limited to this embodiment because various other means can be considered.

Since it is configured as described above, when this is used, each part operates as follows, and has an excellent effect.
As shown in FIGS. 1 and 3, first, when the backrest 1 is gradually raised and inclined, a rectangular hole H to the extent that the patient's buttocks fit into the center of the bed can be formed. Further, when the center footrest portion 21 is slid in the direction of the end of the bed, the rectangular hole H expands in the bed longitudinal direction. In the formed rectangular hole portion H, a defecation device 9 having an inclined toilet seat 92 that is substantially perpendicular to the perforated canvas sheet 5 or the inclined backrest portion 1 is installed. As a result, the user's patient's buttocks are supported in front and back, and the elbows form the rectangular holes of the bed, and the edges of the left and right foot outer portions 22 and 23 act as armrests. Will give you a stable posture, and you will feel safe and comfortable.
Therefore, there is no need for a safety belt or an armrest device used in conventional medical beds.

  Further, as shown in FIGS. 4 and 5, the backrest portion is inclined upward, so that the patient does not turn forward, and the inclined toilet seat 92 that is substantially perpendicular to the backrest portion 1 is in a state of being turned upside down. However, since the patient is substantially seated on a normal chair, the posture of the patient is stabilized especially during defecation, and a feeling of mental relief can be brought about and defecation can be performed smoothly.

  Further, as shown in FIGS. 1 and 7, in cases other than defecation, the handle 58 is rotated before the backrest 1 is tilted, and the buttock retaining stay 55 is set in the forward direction as shown in FIG. As shown in FIG. 7, as the backrest portion 1 is tilted about the support shaft 3, the buried central collar portion 11 is folded in two, and the front bending portion 112 is gradually lifted to face the root fixing portion 111. Since the tip is almost the same height as the end face of the center footrest portion 21, the patient is in a state where the knee is fully extended as shown in FIG. 7, and the left and right sides are also slightly recessed in the center of the bed. Since the weight is applied, the mat stopper function of the left and right foot outer portions 21 and 22 prevents the patient from sliding sideways even when the backrest portion 1 is tilted left and right, and can maintain a stable posture. I'm tired of sitting Rukoto is not.

When the present invention is used as a defecation case, it is used according to the following procedure. (See FIGS. 4 and 5)
1) It is lowered in advance with the operating hand switch of the bed lifting leg driving cylinder 87 until the mat surface 1, 2, 23 of the bed is at the lowest position.
2) Check the position of the patient's recumbent so that the patient's buttocks (caudal bone) are positioned on the upper and lower parting lines of the flooring 6, and move and adjust the position so as to be a predetermined position if necessary.
3) Make sure that the front bending handle 58 of the center buttock 11 is tilted forward (head).
4) Slide the central footrest portion 21 about 30 cm (until it stops at a predetermined position).
When the center footrest portion 21 is fully slid (during defecation), the toilet lid 95 is automatically opened because it is linked to the slide.
If it is not interlocked with 4), the lid of the toilet bowl is opened by another means and an operation for it.
5) If you slowly tilt the backrest 1 to the full stop position (angle), it will automatically open from the center of the flooring 6 and automatically without any special attention from the patient. The buttocks will settle on the tilted toilet seat.
At this time, the patient confirms whether the seating posture on the tilted toilet seat 92 is correct, and if there is a malfunction, the tilt angle of the backrest 1 is adjusted and adjusted.
In addition, when adjustment is still not possible depending on the patient's physique, etc., the bed is returned to its original state, and then the position where the defecation device 9 is installed is adjusted back and forth with a spacer or the like.
6) Use a relaxed and stable posture.
7) Treat the area (wash and dry) after defecation. (For cleaning / drying type)
8) After defecation is completed, it can be restored by operating in reverse order.

Moreover, when using it as a case other than defecation, it becomes the following procedures. (See Figs. 6 and 7)
1) Tilt the forward bending / extending handle 58 of the center buttock 11 to the opposite side to the front (foot) defecation.
2) Slide the center footrest part a little (about 10 cm). At the same time, the knee is raised, so if you do not want to bend the knee, slide it further.
3) The backrest is inclined at an arbitrary angle.
4) When it is horizontal, it can be restored by operating in the reverse procedure.
5) Return the handle to its original position.

FIG. 12 is a schematic mechanism diagram showing an inclined state of the backrest portion provided with a lifting device according to another embodiment of the present invention.
As shown in FIG. 12, auxiliary legs 85 are provided on the front and rear sides as means for moving up and down the floor matting plate or the whole mat that is integrated with the floor receiving plate for holding the upper and lower body of the patient. Are connected to the base 88, and a leg drive cylinder 87 is provided. Note that the lifting device for the entire bed is not limited to this embodiment because various other means can be considered. For example, it can be a pantograph type or a screw type.

13A is a perspective view illustrating a state in which the flooring of the present invention is mounted on a mat, and FIG. 13B is a perspective view illustrating a state in which a rubber band or a reinforcing cloth is attached to the lower body flooring. is there.
As shown in FIG. 13 (a), a cloth having a size covering the entire mat of the bed is divided into two in a straight line transversely at the position of the convex portion of the backrest 1, and the upper upper cloth 61 is divided into two parts. As shown in FIG. 13 (a), the cloth was stretched in the direction perpendicular to the bed axis while providing a gather 64 on the cloth, along the lower edge of the cloth, exceeding the convex width of the central collar 11 of the backrest 1 Attach split section crossing rubber band (bib) body 63 so as to sew in the state, and provide hooks with split corner rubber cloths that fix both ends in the vicinity of both sides of the bed in a cross shape, and mats for upper and lower mattresses The corner portion is provided with a corner stopper rubber cloth 69 so as to face each other at 45 degrees.
Further, as shown in FIGS. 13A and 13B, at least one central rubber cloth hook 65 is provided at the upper and lower central parts of the lower body cloth 62, and a pair of long rubber bands at the upper central part. 66 is provided so as to be symmetrical with respect to the center axis of the bed with a predetermined interval and to extend to the upper end edge of the backrest portion so as to sandwich the convex portion of the backrest portion so that the tip can be fixed with a hook. Keep it. Further, as shown in FIG. 13 (b), on the back side of the lower half cloth 62, a rectangular, trapezoidal or triangular shape having a total width of 25% of the entire width of the lower half cloth 62 and a width of 25% of the width between the pair of long rubber bands 66 at the upper center portion. The reinforcing cloth 67 is fixed to the upper and lower ends, and about one third of the length is adhered or stitched.
Various materials can be used for the cloth for matting, and cotton or vinyl may be used.

In this way, by segregating the divided portion crossing rubber band 63 while providing the gathers 64 on the upper body cloth 61, the gathers act to adjust the margin of the cloth, so that the edges of the cloth are not stretched during use. Open. At the same time, the pair of long rubber bands 66 at the center of the upper end of the lower body cloth 62 hold the patient's body moderately from the left and right when the backrest 1 is tilted, and make the upper end of the lower body cloth 62 smooth when restoring. Acts to raise.
In addition, the reinforcing cloth 67 acts to disperse the force applied to the floor cloth, and an unreasonable wrinkle is generated since an excessive force concentrated on a part of the floor cloth is not applied during the sliding of the center footrest portion. It can prevent or improve the durability of the flooring.
