Description

  The present invention relates to a bathing aid used by a person with a physical disability, particularly a person with reduced mobility, during bathing.

  When a person with reduced mobility takes a bath, since the tension of the foot does not work, it takes a bath using the strength of the arm. In other words, put your hands on the edge of the bathtub, crawl the legs of the handicapped and support your weight with both arms and shift your body to put your free leg in the bathtub, and then put it in the bathtub Folding your knees, bending your body and sinking in hot water, but for people with weak arms, supporting the weight with both arms is a hard work with great difficulty. Therefore, it has been proposed to use a bathing aid for the purpose of reducing such a burden (see Patent Document 1).

  This conventional bathing aid has an air mat in which an air bag is housed and air supply / exhaust means for taking air into and out of the air bag.

  When bathing using a conventional bathing aid, the air mat with air in the air bag is floated on hot water and placed on the air mat. And the air supply / exhaust means is operated in a state where it is on the air mat, and the air in the airbag is discharged little by little. Then, the air mat is deflated and the buoyancy received from the hot water gradually decreases and begins to sink, so that the body can be attached to the hot water.

  When rising from the hot water, the air supply / exhaust means is operated to inject air into the airbag. Then, the air mat swells, and the buoyancy received from the hot water increases, so that it floats with the body, thereby raising the body from the hot water.

Japanese Patent Laid-Open No. 2002-238773 (FIG. 4)

In conventional bathing aids, the air mat floating in hot water is very unstable, and the act of riding on it is a heavy labor with great difficulty especially for people with reduced mobility.
In addition, the conventional bathing aid has a problem in that it requires a large device such as an air supply / exhaust device, so that the manufacturing cost is high.

  The present invention has been made in view of such conventional problems, and it is an object of the present invention to provide a bathing assisting device that allows a person with reduced mobility to bathe on their own at low cost.

The invention described in claim 1 is “a bathing aid 10 having a rectangular plate shape having a specific gravity smaller than the hot water in bathtub B,
The length x between the adjacent sides 10b, 10b of the bathing aid 10 facing the inner surface on the long side of the bathtub B is set to be shorter than the inner width X on the short side of the bathtub B,

  According to the third aspect of the present invention, “the upper surface 10c of the bathing assistance device 10 is provided with the protruding portion 12 from the side 10a ′ where the protruding portion 12 is not provided or from the vicinity of the side 10a ′. The buttock mounting recess 18 leading to 10a is recessed ".

  According to the bathing aid 10 according to claim 1, the length x between the adjacent sides 10 b and 10 b of the bathing aid 10 facing the inner surface on the long side of the bathtub B is the inner width on the short side of the bathtub B. If the rear side 10a 'between the adjacent sides 10b and 10b is set to be parallel to the short side of the bathtub B, the bathing assisting device 10 is fit in the bathtub B. I can float. And if it moves in front of the bathing auxiliary appliance 10 which floated in hot water and sits down on the bathing auxiliary appliance 10 as it is, the body will slowly sink into the hot water together with the bathing auxiliary appliance 10 by the buoyancy of the bathing auxiliary appliance 10. be able to. At this time, the body is lifted by the buoyancy applied to the bathing assisting device 10 (the weight is reduced by the amount of buoyancy), so the weight applied to both arms on the edge of the bathtub B during bathing is greatly reduced, and the foot is inconvenient. Even a simple person can take a bath alone without placing a burden on both arms.

  Moreover, since the protrusion part 12 is formed in the center part of the front side 10a of the bathing assisting device 10, if the projecting part 12 is sandwiched between the right foot and the left foot, the waist assisting device 10 is directly supported by the waist. The seating position is determined by simply lowering, and there is no worry of losing balance when sitting on the bathing aid 10 and sinking in hot water.

  Furthermore, since the outer peripheral surface 14 of the bathing assisting device 10 is an inclined surface facing toward the lower surface 10d, when the bathing assisting device 10 is submerged in hot water, the hot water on the lower surface 10d side of the bathing assisting device 10 is inclined. Accordingly, the posture of the bathing assisting device 10 is stabilized, so that the bathing assisting device 10 can be sunk straight without tilting.

  The bathing aid 10 is formed of a plate-like member having a specific gravity smaller than that of hot water, and does not require a complicated mechanism such as a conventional air supply / exhaust means. Can be manufactured.

  According to the second aspect of the present invention, when the bathing assisting device 10 is submerged in hot water, the hot water on the lower surface 10d side of the bathing assisting device 10 can be released from the draining hole 16 to the upper surface 10c side. The resistance when sinking the bathing aid 10 is reduced, and the bathing aid 10 is easily submerged in hot water.

  According to the invention described in claim 3, the heel portion mounting recess 18 is provided toward the front side 10 a where the protruding portion 12 is provided on the upper surface 10 c of the bathing assisting device 10, so that the heel portion is It fits into the buttocks placement recess 18 and can sit on the bathing aid 10 more comfortably.

It is a figure which shows the example which provided the buttock mounting recess in the upper surface of the bathing assistance instrument. It is B-B 'sectional drawing in FIG. It is the example which provided the recessed part for legs in the base end part of the protrusion part.

  The present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing a bathing assisting device 10 according to the present invention, FIG. 2 is a plan view of the bathing assisting device 10, FIG. 3 is a side view of the bathing assisting device 10, and FIG. 2 is a cross-sectional view taken along line AA ′ in FIG.

  As these figures show, the bathing aid 10 of the present invention is a rectangle (a rectangular shape or a square shape) formed of a synthetic resin having a density lower than that of hot water stretched in the bathtub B. It is a plate-shaped member and the inside is hollow.

  The bathing aid 10 may be rectangular or square as described above, but a rectangular shape will be described below as a representative example. The adjacent sides 10b and 10b of the bathing assistance device 10 facing the inner surface of the long side of the bathtub B are short sides, and the sides 10a and 10a 'between the adjacent sides 10b and 10b are long sides. The long side 10a is the front side (abdominal side of the seated person), and the long side 10a 'is the back side (back side of the seated person).

  The length x of the long sides 10a and 10a 'is set to be shorter than the inner width X on the short side of the bathtub B, and the short side 10b is close to the inner surface on the long side of the bathtub B.

  The width y of the short side 10b of the bathing assisting device 10 is set to such a length that the user can sit on the bathing assisting device 10. Moreover, the diagonal length z of the bathing auxiliary appliance 10 is set longer than the inner width X of the short side of the bathtub B (refer FIGS. 5-6).

  A protruding portion 12 is extended from the central portion of the long side 10 a on the front side of the bathing assistance device 10. The protrusion 12 has a substantially isosceles triangular shape in plan view and is formed so as to become narrower toward the tip when viewed from the plane, and the tip is rounded. The size of the projecting portion 12 is appropriately set so that the projecting portion 12 is sandwiched between the right foot and the left foot when the bathing assisting device 10 is floated in hot water and both feet are slightly opened in front of the bathing assisting device 10. .

  The outer peripheral surface 14 of the bathing aid 10 is an inclined surface that is inclined inward toward the bottom surface 10d, and the inner angle of the outer peripheral surface 14 with respect to the upper surface 10c is formed as an acute angle. The inclination angle is appropriately set in consideration of resistance when sinking the bathing aid 10.

  The bathing aid 10 is formed with a water draining hole 16 that allows the upper surface 10c and the lower surface 10d to communicate with each other. The drain holes 16 are provided as necessary, and the size and number of the holes 16 are appropriately set in consideration of resistance when the bathing aid 10 is submerged in hot water, as is the inclination angle of the outer peripheral surface 14. Is done. For example, as shown in FIG. 2, one drainage hole 16 may be formed in the center portion of the bathing assisting device 10, and as shown in FIG. You may make it form each (two in total). In addition, the drain hole 16 has a straight inner wall in this embodiment, but although not shown, it is formed in a tapered shape so that the inner diameter of the lower end is larger than the upper end. Also good.

  In the present embodiment, as described above, the bathing aid 10 is made of a synthetic resin and is configured as a hollow plate-like member, but the material and structure thereof are not necessarily limited to the above. It may be configured as a shaped member (closed cell type resin plate), wood may be used as a material, and it may be configured to float by buoyancy when floated on hot water.

  When bathing using the bathing assisting instrument 10 configured as described above, first, the bathing assisting instrument 10 is floated on hot water so that the protruding portion 12 faces forward. Next, as described above, both hands are put on the edge of the bathtub B, and the body is shifted while supporting the weight with both arms while scooping the leg of the handicapped person, and the legs are placed on both sides of the front protrusion 12 of the bathing aid 10. In the bathtub B, after that, the knee of the leg in the bathtub B is folded, the body is bent and it is submerged in hot water. And both hands are put on the edge of the bathtub B, and it sits on the bathing assistance instrument 10, bending little by little. At this time, the position to sit on the bathing aid 10 is uniquely determined by standing so that the protruding portion 12 is sandwiched between both feet.

  At this time, when the hot water surface undulates, the bathing assisting device 10 floating on the hot water may be applied with a force in the direction of rotating the hot water, but the bathing assisting device 10 of this embodiment is Since the length z is set to be longer than the inner width X on the short side of the bathtub B, the outer peripheral surface 14 is immediately applied even when a force in the direction of rotating the hot water is applied to the bathing aid 10. Further contact with the inner wall of bathtub B restricts further rotation. Therefore, it is not necessary to hold the bathing assisting device 10 so that it does not face an undesired direction, and it is possible to sit down simply by standing in front of the bathing assisting device 10 and sitting down.

  After sitting on the bathing aid 10, it is only necessary to leave the body in the bathing aid 10 while supporting the weight with both hands on the edge of the tub B. It will sink quietly. At this time, since the buoyancy (upward force) applied to the bathing assisting device 10 sinks while lifting the body, the burden on both arms supporting the weight is greatly reduced, and even a person with weak arm strength can bathe the body together with the bathing assisting device 10 with hot water. Can sink into.

  In addition, since the outer peripheral surface 14 of the bathing assisting device 10 is an inclined surface in the downward inner direction, when the bathing assisting device 10 is submerged in hot water, the hot water on the lower surface 10d side of the bathing assisting device 10 is along the inclined surface. As a result, the posture of the bathing assisting device 10 is stabilized, so that the bathing assisting device 10 can be sunk straight without tilting. In addition, since the hot water on the lower surface 10d side of the bathing assisting device 10 can be released to the upper surface 10c side through the draining hole 16, resistance when the bathing assisting device 10 is submerged in hot water is reduced. It should be noted that the speed at which the bathing aid 10 sinks can be adjusted by appropriately setting the taper angle of the inclined surface of the outer peripheral surface 14 and the size and number of the drain holes 16.

  When you get out of the hot water, try to float the upper body a little in the hot water. Then, since the body is lifted by the buoyant force applied to the bathing assisting device 10, it is possible to stand up easily without requiring the force of the arm or by simply assisting with the arm.

  Thus, according to the bathing assisting instrument 10 of the present embodiment, it is configured as a rectangular plate that is configured to float by buoyancy, and does not require a complicated mechanism as in the prior art, so it is inexpensive. Can be manufactured.

  In addition, by using the buoyancy applied to the bathing assisting device 10 floated on hot water, even a person with reduced mobility can easily bathe.

  As shown in FIGS. 7 to 8, on the upper surface 10 c of the bathing assisting device 10, the heel mounting recess 18 reaching the side where the projecting portion 12 is provided from the long side 10 ′ on the rear side or You may form from a near position, and in this case, the effect that a seating comfort improves by sitting a buttocks according to the buttocks mounting recess 18 is acquired.

  Moreover, as shown in FIG. 9, you may make it form the recessed part 20 for legs in the base end part (boundary part with the long side 10a) of the protrusion part 12, By providing such a recessed part 20 for legs, it is good. Sitting comfort can be further enhanced.
