BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bathing assistance board for assisting a bathing of an elderly person, especially a person with a handicap who has a disability in the lower body.

[0002]

2. Description of the Related Art Conventionally, a bathing assistance board 100 as shown in FIGS. 11 and 12 disclosed in Japanese Patent Application Publication No. 841922 is known. Note that FIG.
Is a perspective view of the bathing board 100, and FIG. 12 is a sectional view thereof. The bathing board 100 is inserted between upper edges of the bathtub 200 facing each other. The bathing board 100 has a plate-shaped board body 101 and an upside-down face provided on one surface of the board body 101. It comprises a grip bar 102 having a U-shape, and adjusters 103 provided on both longitudinal sides on the back side of the board main body 101.

[0003] The board body 101 is formed in a rectangular shape so as to be installed between the longitudinal edges of the bathtub 200, and the buttocks of a bather are placed on the center of the board body 101. The bather once sits with his buttocks on the board body 101 and then enters the bathtub 200. The board main body 101 is provided with a total of four long holes 120, each pair of which extends in the longitudinal direction from near the short side edge.

[0006] As shown in FIG. 12, the adjuster 103 has a guide rail 104 having a long through hole attached to each of the long holes 120, and a guided plate that can be moved forward and reverse by being guided by the guide rail 104. 105 and the guided plate 1
Rod 1 projecting downward from slot 05 through slot 120
06, an inverted truncated cone-shaped cushioning member 107 attached to the lower end of the rod 106, and a bolt 108 that passes through the guided plate 105 and is attached to the guide rail 104.
And a nut 109 screwed to the bolt 108. The grip bar 102 is mounted on the board body 1.
A pair of lower ends are fixed to each guided plate 105 via a pair of long holes 120 formed in one edge of the first plate 01.

After the board body 101 is bridged between the opposing edges of the bathtub 200, each rod 106 is operated to move each pair of guided plates 105 in the direction away from each other, and the buffer member 107 is moved. By tightening the nut 109 in a state of being in contact with the inner surface of the bathtub 200, the guide rail 104 is fastened by the head of the bolt 108 and the nut 109, so that the movement of the adjuster 103 is prevented.

[0006] In this state, the cushioning member 107 is connected to the bathtub 20.
By contacting the inner surface of the bath 0, the lateral displacement of the board main body 101 with respect to the bathtub 200 is prevented, so that the installation state of the bathing board 100 with respect to the bathtub 200 is stabilized.

[0007]

In the conventional bathing board 100 as described above, first, when a bather tries to straddle the edge of the bathtub 200 while holding the grip bar 102, the user holds the grip bar 102. There is a problem that the hand must be extended from the back to the back, the posture becomes unstable, and the balance is easily lost.

Further, after the bather sits on the board body 101 and then moves from the sitting position to the standing position before moving into the bathtub 200, the toes of the feet are landed on the bottom plate of the bathtub 200. In order to perform the operation, the thigh is pivoted forward and downward about the joint between the femur and the pelvis as a fulcrum. In order to perform such a turning operation, it is necessary to shift the buttocks to the front edge of the board body 101, but this operation is very difficult for elderly people and persons with a handicap. There are inconveniences.

The board body 101 is provided with a cushioning member 10.
7 is in contact with the inner wall surface of bathtub 200 and bolt 108
Is fixed to the bathtub 200 by performing the fastening operation, and there is also an inconvenience that the mounting of the board body 101 to the bathtub 200 requires a troublesome turning operation of the bolt 108.

Further, even if the board body 101 is to be installed on the end of the bathtub 200, the cushioning member 107 is not provided.
0, the board body 101 cannot be moved further toward the end.
There is also a problem that the front portion of the board body 101 at 00 becomes too small.

The present invention has been made in order to solve the above-mentioned problems, and the operation posture of a bather when entering a bathtub is stabilized, thereby smoothly changing the posture from a sitting position to a standing position. It is an object of the present invention to provide a bathing assistance board which not only can perform the bathing operation widely, but also can widen the inside of the bathtub, and can easily mount the board body on the bathtub.

[0012]

According to the first aspect of the present invention,
A bathing assistance board that is bridged between opposed edges of a bathtub and is used to temporarily sit down before a bather enters the bathtub, comprising a board body and a gripping member attached to the board body. The board body comprises a seating area on which a bather sits, and a gripping member mounting area to which the gripping member integrally extended from the seating area in the longitudinal direction is mounted, The grip member has a grip portion protruding forward from an edge on the long side of the seat area.

According to the present invention, since the holding portion of the holding member held by the bather protrudes forward from the long side edge of the seating area of the board body, the bather can temporarily use one hand during the bathing operation. By twisting the body while placing one foot in the bathtub while holding the grip, placing the buttocks on the center part of the board body, the buttocks rest on the hips with the hand holding the grips in front of the body On. Then, by putting the left foot in the bathtub, the bather is seated on the board body. Subsequently, the bather can be immersed in hot water in the bathtub by shifting the buttocks toward the inside of the bathtub while holding the grip bar.

As described above, since the grip is provided at a position protruding forward from the edge on the longitudinal side of the board body,
The bather can hold the grip with the hand extended at all times during the bathing operation, and by moving the body forward with force on the gripped hand, the body is moved through the board body. And can be easily moved.

Therefore, in a conventional auxiliary board in which the grip portion of the grip bar does not extend forward from the board body, one foot is put into the bathtub when the bathing operation of the bather, and the buttocks are placed on the board body. In a state where the body is twisted, the hand holding the grip bar is located behind the body, which not only makes the bathing operation of the bather unstable, but also after sitting on the board body once, standing from the sitting position When the body moves forward, there is a disadvantage that the hand holding the grip bar is positioned behind the body due to the forward movement of the body, and the posture becomes unstable. Even if the elderly and the handicapped have no such inconveniences, they can easily bathe on their own in the case of minor disability, and the labor of the caregiver in the case of severe disability. Is Gensa.

According to a second aspect of the present invention, in the first aspect of the present invention, the holding member mounting area is set to be wider than the stool area.

According to the present invention, the structure for attaching the gripping member to be attached to the board body is simplified.

The third aspect of the present invention is the first or second aspect.
In the described invention, the gripping member is formed by a grip bar extending in a short direction of the board body.

According to the present invention, the gripping member can be reliably gripped with a simple structure.

According to a fourth aspect of the present invention, in the first aspect of the present invention, the board body has an arcuate edge formed by cutting a central position of a front end edge into an arcuate shape. , And the arc-shaped edge portion has an inclined surface inclined forward and downward.

According to the present invention, when the bather is seated on the board main body, the lower surface of the thigh is located on the inclined surface of the arc-shaped edge inclined forward and downward. As the bather sitting in the room moves from sitting to standing,
Since the thighs and buttocks are located on the inclined surface of the arc-shaped edge, it is guided on the inclined surface of the arc-shaped edge without particularly sliding the buttocks forward on the board body. The thigh itself can be shifted downward from the sitting position to the standing position, and the bather can easily move from the board body into the bathtub. Therefore, in the conventional auxiliary board, when moving from the board main body into the bathtub, a difficult operation of shifting the buttocks and temporarily moving to the edge of the board main body is forced, but in the invention of claim 4, Such a conventional disadvantage does not occur.

A fifth aspect of the present invention is characterized in that, in the fourth aspect of the present invention, the downwardly inclined surface is provided vertically symmetrically in the board body.

According to the present invention, since the downwardly inclined surface is formed on the front and back of the board body, it can be used even when the board body is turned upside down. Therefore, it is possible to select which one of the front and back sides of the board body is to be used on the upper side depending on the installation layout of the bathtub and whether the bather is right-handed or left-handed, and the board body is versatile. It becomes something.

According to a sixth aspect of the present invention, in the first aspect of the present invention, the board body includes:
A regulating member for regulating movement to the bathtub is provided on the back side, the regulating member is a rail member laid on the back side of the board body so as to extend in the longitudinal direction or the longitudinal direction and the transverse direction, and the rail member It is provided with an adjuster provided with a lock structure that can be guided by a member and that prevents movement at an arbitrary position, and a buffer member attached to the adjuster so as to face the inner wall surface of the bathtub. It is assumed that.

According to this invention, the adjusters are moved in the direction away from each other along the rail member while the board body is laid between the opposing edges of the bathtub, and each buffer member attached to the adjuster is moved to the inner surface of the bathtub. Then, the board body is mounted on the bathtub by locking the adjuster so as not to move by operating the lock structure. And, in the state where the board body is attached to the bathtub, the adjuster is stopped on the inner surface of the bathtub via the buffer member,
The mounting state is stabilized by the reaction force due to the elastic deformation of the cushioning member, and the inconvenience of damaging the inner surface of the bathtub is avoided.

In particular, by laying the rail member also in the short direction, the position of the adjuster guided by the short rail member is adjusted, thereby positioning the board body in the longitudinal direction of the bathtub. It can be carried out. This positioning also allows the long edge of the board body to be placed on the short edge of the bathtub, which allows the front of the board body to be widened in the bathtub with the board body attached to the bathtub. Become.

According to a seventh aspect of the present invention, in the invention of the sixth aspect, the adjuster includes an adjuster body which is guided and moved by the rail member, and a latch shaft having an external tooth latch penetrating the adjuster body. A locking piece provided on the adjuster body and having an internal tooth latch that meshes with the external tooth latch of the latch shaft; and a locking piece that faces in a direction in which the internal tooth latch meshes with the external tooth latch. The latch shaft is mounted in the rail member so that the adjuster body can move toward the edge of the board body, and the lock structure includes a latch mechanism. It is constituted by a shaft and internal teeth of a locking piece, and the buffer member is attached to the adjuster body.

According to the present invention, when the adjuster body is pressed toward the inner wall surface of the bathtub, the latch inner teeth of the locking pieces ride on the latch outer teeth of the latch shaft, so that the locking pieces act as biasing means. The latching piece moves in a direction away from the latch shaft against the urging force, and when the latch inner tooth faces the next latch external tooth, the locking piece returns to the original position by the urging force of the urging means, and this operation is performed. By continuing, the adjuster moves in the pressing direction.

On the other hand, even if the adjuster body is pressed in a direction away from the inner wall surface of the bathtub, the movement of the adjuster body is prevented because the latch inner teeth interfere with the latch outer teeth.

Therefore, the cushioning member is brought into contact with the inner wall surface of the bathtub by only a simple operation of pressing the adjuster body toward the inner wall surface of the bathtub while the board main body is installed between the edges of the bathtub. Once the buffer member abuts against the inner wall surface of the bathtub, the adjuster body is prevented from moving in the opposite direction once the buffer member abuts against the inner wall surface of the bathtub. The operation of fixing the board body to the bathtub becomes easier as compared with the conventional one in which the board body cannot be fixed to the bathtub unless it is performed.

A pair of such adjusters are provided so that the adjuster bodies can move in the longitudinal direction of the board body, and the other pair can be moved in a manner that the adjuster bodies can move in the transverse direction of the board body. In this way, the board body can be prevented from moving in the short direction of the bathtub by a pair movable in the longitudinal direction, and the pair movable in the short direction can be formed by the inner wall surface on the short side of the bathtub. And the board body is prevented from coming off the bathtub.

In addition, since the position of the adjuster body can be set so that the board body is placed on the short edge of the bathtub, the adjuster becomes an obstacle, and the board body is moved to the short side of the bathtub. On the edge of the board body, thereby avoiding the conventional disadvantage that the space in the bathtub on the front side of the board body becomes too small.

[0033] The invention according to claim 8 is the invention according to claim 6 or 7.
In the described invention, the buffer member is attached to the adjuster so as to swing.

According to the present invention, even if the inner wall surface of the bathtub is inclined, the swingable buffer member is inclined following the inclination of the inner wall surface, so that the buffer member always contacts the inner wall surface of the bathtub by surface contact. Thus, the movement inhibition state of the board body is stabilized.

Next, the bather can be immersed in the hot water in the bathtub 70 by shifting the buttocks toward the inside of the bathtub 70 while gripping the grip bar 30. In particular, in the board body 20, the side on which the grip bar 30 is provided is protruded outward from the edge on the side on which the user sits, and is longer than the other side. 22 is formed, and the grip bar mounting area 22 is formed.
Since the grip bar 30 is provided so as to cover the entire width of the body, the bather twists the body slightly during the bathing operation, and holds the grip bar 30 with one hand in a posture where the buttocks naturally face the center of the board body 20. It is natural and easy to move from the outside of the bathtub 70 to the board body 20 with the buttocks naturally positioned at the center of the board body 20 when one foot is put into the bathtub 70 when the user grips it. Can be

When the bather is seated on the board body 20, the hand is extended forward and the grip bar 3 is naturally lifted.
Since the body is in the posture of gripping 0, the body can be moved into the bathtub 70 very easily by moving the body forward with force on the gripped hand.

Therefore, the grip bar 30 is connected to the board body 2
In the conventional bath assisting board 100 (FIGS. 11 and 12) which is not extended to the front of the bath body 0, one foot is put into the bathtub 200 when the bathing operation of the bather is performed, and the board body 10
In a state where the body is twisted so that the buttocks are placed on the body 1, the hand holding the grip bar 102 is located behind the body, which not only makes the bathing operation of the bather unstable, but also temporarily puts on the board body 101. After sitting, even when changing the posture from the sitting position to the standing position and entering the bathtub 200, the hand holding the grip bar 102 is positioned behind the body due to the forward movement of the body, and the posture is not good. Although there is an inconvenience of being stable, such an inconvenience does not occur in the bathing assistance board 10 of the present invention. It is possible to take a bath easily and to reduce the labor of the caregiver even in the case of severe disability.
