Description

[Detailed Description of the Invention] <<Industrial Application Field>> The present invention relates to an elevating type bathing device suitable for use in bathing the elderly or physically disabled or bathing the deceased.
The present invention relates to a method for adjusting the height of the bathtub and the fixed stand on which a human body or corpse is placed to a height that is easy to use.

<Prior Art> Generally, bathing a disabled person involves many difficulties for the caregiver, so the bathtub is raised and lowered by a desired power mechanism, so that the disabled person can lie on his/her back. The stretcher placed on the carrier is placed next to a fixed stand installed in the bathtub, and after the stretcher is transferred onto the fixed stand, the bathtub that was at the lower level is raised to allow the child to take a bath. In this way, an elevating bathing device devised to allow a disabled person to take a bath without moving has already been proposed.

In other words, as this type of elevating bathing device,
As illustrated in Figures 4 and 5, the main body of the device a has internal lifting mechanisms, hot water supply, water supply, drainage control mechanisms, etc.
The bathtub b is supported in a cantilevered state by a fork c or the like, and one end of the fixing base d is supported on the device body a, and the other end is supported on the support e that passes through the bottom surface b' of the bathtub b. The structure is as follows.

However, in the above-mentioned elevating type bathing device in which only the bathtub moves up and down by fixing the column to the fixed column, in order to ensure that the person, such as a person with a disability, placed on the fixed base d, is fully immersed in the hot water of the bathtub, the fixed column is fixed. The bathtub b will be raised to the position where the bottom wall of the bathtub b comes into contact with the platform d, but of course the height of the fixed platform d is determined by the length of the support column e, so no more Bathtub b could not be raised, and the height of the bathtub was set at a predetermined position as shown in Figure 5. Therefore, the caregiver (washer)
Depending on the height and physique of the person, the height of the bathtub b and the fixed base d may be too low, or may be too high, making it difficult to wash. If the height is too high, the bathtub b can be lowered to the desired height, but since the height of the fixed base d remains unchanged, it may become impossible to fully immerse the subject in the hot water in the bathtub b. , there are problems in use.

<<Problems to be Solved by the Invention>> The present invention has been made in view of the above-mentioned problems of the prior art. A column penetrates the wall in a liquid-tight manner and supports a fixed base at the upper end, and is made freely expandable and contractable in the axial direction.
In addition, the length of the fixed base in the contracted state is such that it can be held in accordance with the height of carrying in the stretcher, and the bathtub has a length that corresponds to the height of carrying in the stretcher. After passing the intermediate position, until reaching the upper limit position, the fixed base is raised and lowered by the movement of the bathtub, and the height of the flange surface of the bathtub and the top surface of the fixed base is adjusted. without changing the difference,
The purpose is to allow the user to hold the bathtub and fixed stand and adjust it to a convenient height.

<<Means for Solving the Problems>> In order to achieve the above-mentioned object, the present invention provides a lift-type bathtub supported by a lifting mechanism, and a column supported by a support that penetrates the bottom wall of the bathtub in a liquid-tight manner. A method for adjusting the height of an elevating type bathing device comprising a fixing base, wherein when the bathtub is at the lower limit position, the length of holding the fixing base corresponding to the stretcher carrying height is reduced. The support is formed to be extendable in the axial direction so as to be able to extend from this length to the upper limit position of the bathtub, and to extend the bathtub from the lower limit position to a position corresponding to the stretcher carrying height of the fixed base. After reaching the raised intermediate position, the bathtub is further raised and the fixed base is raised together with the bathtub to the required height to the upper limit position by extension of the support. The purpose is to provide a height adjustment method.

<<Operation>> In the reduced state where the length of the column is the smallest, the column is held so that the fixing platform is adapted to the stretcher loading height.

At this time, the bathtub is held at the lower limit position so as not to get in the way of transferring the subject, such as a disabled person, to the fixed table along with the stretcher.

In this state, the stretcher with the subject lying on its back is placed on a carrier and laid on a fixed stand in the bathtub, and after the stretcher is transferred onto the fixed stand, the bathtub is raised.

When the bathtub rises to the intermediate position, the bottom wall of the bathtub comes into contact with the lower surface of the fixed base, so when the bathtub is moved upward from the intermediate position, a lifting force acts on the fixed base via the bathtub. As a result, the support column is extended in the axial direction, and the fixing base is raised to the upper limit position together with the bathtub, and is held at that position.

In this way, the bathtub raises the fixed base from the intermediate position to the upper limit position, so it can be moved from the intermediate position when used at a low position, to the upper limit position when used at a high position, and from the intermediate position to the upper position when used at a high position. At any position up to the upper limit position, the distance from the opening edge (flange surface) of the bathtub to the top of the fixed base remains constant without changing.

Next, when the bathtub is lowered from the above-mentioned upper limit position, the fixing base is lowered together with the bathtub as the lifting force is released, and is lowered to the above-mentioned intermediate position where it is stopped and held.

On the other hand, the bathtub is lowered from the intermediate position to the lower limit position by the lifting mechanism and is stopped and held at that position.

<<Example>> Hereinafter, an example of the present invention will be described with reference to the drawings.

FIGS. 1 to 3 show an elevating type bathing device as an example that can be used in carrying out the method according to the present invention, and show respective longitudinal sections when the bathtub is at the lower limit position, intermediate position, and upper limit position, respectively. A side view is shown.

The illustrated elevating bathing device is, as is known, equipped with an elevating mechanism driven by a motor or hydraulic pressure, a hot water supply, a water supply, a drainage control mechanism, etc., and is installed on a floor 1 and has an elevating mechanism (not shown). As the main body is operated, an elevating bathtub 2 connected to the main body can be moved up and down using power.

A fixed stand 3 on which a human body can be placed is arranged in the bathtub 2, and the fixed stand 3 is
It is supported by a column 4 that penetrates the bottom wall 2a of the bathtub 2 in a liquid-tight manner and is fixed to the floor 1.

Further, a sealing mechanism (not shown) is provided at a portion where the support column 4 penetrates the bottom wall 2a of the bathtub 2, and leakage of hot water from this portion is prevented by a desired means.

In the present invention, the support column 4 is formed to be expandable and contractible in the axial direction.

The illustrated column 4 is formed by fitting a first column 4a and a second column 4b so as to be slidable in the axial direction, and this sliding portion 5 is formed by fitting a first column 4a and a second column 4b such that they can slide freely in the axial direction.
A small-diameter portion 4c of a required length is formed at the upper part of the second support column 4b, and a recessed hole 4d, into which the small-diameter portion 4c fits, is opened downward at the center of the lower part of the second support column 4b. The small diameter portion 4c is slidably fitted into the holder.

Also, this support 4 has a minimum length l when it is reduced.
is set in advance to a length that will hold the fixed base 3 in accordance with the height at which the stretcher is carried in, and the maximum length is
The length is set to match the height when the bathtub 2 is set at the required upper limit position, or is set longer by an appropriate dimension.

To carry out the present invention using the elevating bathing device configured as described above, the following procedure is followed.

When the bathtub 2 is lowered to the lower limit position A shown in FIG.
is maintained.

In this state, it is preferable that the fixing base 3 be held at a position directly above the bathtub 2 and slightly higher than the flange surface of the bathtub 2.

In other words, the stretcher on which the subject, such as a person with a physical disability, is lying on its back is placed on the carrier and placed on the fixed base 3, and the fixed base 3 is held at a height that makes it easy to transfer the entire stretcher onto the fixed base 3. be.

After transferring the subject onto the fixed base 3 at the lower limit position A of the bathtub 2, the bathtub 2 is raised until the inner surface 2c of the bottom wall 2a comes into contact with the lower surface 3a of the fixed base 3. , this is the intermediate position B shown in FIG.

At this time, as the bathtub 2 rises, the fixing base 3 sinks to the bottom of the bathtub 2.
The subject can be fully immersed in the hot water in the bathtub 2.

That is, this intermediate position B becomes the low usage position of the bathtub 2.

When the bathtub 2 is further raised from the intermediate position B, a lifting force is applied to the fixing base 3 through its bottom 2a, so that the telescopic column 4 extends in the axial direction, raising the bathtub 2 to the third position. It will be raised to the upper limit position C shown in Fig. 3.

In other words, the bathtub 2 can be placed at a desired high use position that is higher than the intermediate position B by a required dimension.

Also, at this time, the fixing base 3 is
follows and moves up and down between the intermediate position B and the upper limit position C, so that when the flange of the bathtub 2 The distance h from the surface 2b to the top surface of the fixed base 3 does not change, so no matter which height is adjusted above, the subject is not placed in the bathtub 2.
It can be fully immersed in the hot water inside.

Also, when the bathtub 2 is lowered from the upper limit position C,
When the subject is placed on the fixed table 3, the support column 4 shrinks due to the weight of the subject and the fixed table 3, and when no subject is placed on it, the column 4 contracts due to the weight of the fixed table 3.
The fixed base 3 can be lowered together with the bathtub 2 and placed in an intermediate position B.

When the bathtub 2 is further lowered, only the bathtub 2 descends to the lower limit position A and stops, while the fixing base 3 stops descending at the height of the reduced minimum length of the support 4, resulting in the state shown in Fig. 1. is maintained.

Incidentally, in the illustrated example, the support column 4 is composed of two first and second support columns 4a and 4b.
It can be formed by two or more pillars slidably fitted together, a pantograph, or any other arbitrary structure.

<<Effects of the Invention>> The present invention allows the heights of the bathtub and the fixed stand to be adjusted as explained above. has an arbitrarily set expansion/contraction stroke in the axial direction, and changes the distance between the flange surface of the bathtub and the fixed base between the intermediate position B and the upper limit position C, excluding the lower limit position A of the bathtub. Without, the bathtub,
Since the height of the fixing table is adjustable, it is possible to adjust the height to the user's preference for ease of use, while keeping the subject fully immersed in the hot water in the bathtub.
