Abstract

PURPOSE:To position a bathtub to desired height which is convenient for a bathing assitant by adjusting the height of a bathtub and a fixing stand without changing a distance between the flange surface of the bathtub and the fixing stand between an intermediate position and an upper limit position excepting the lower limit position of the bathtub. CONSTITUTION:In a bathtub 2, a fixing stand 3 is arranged to load a human body and supported by a supporter 4, which is passed through a bottom wall 2a of the bathtub with a liquid-tight condition and fixed on a floor surface, and the supporter is formed so as to be freely extended/contracted in an axial direction. When the bathtub is set in a lower limit position A, the supporter is held by a minimum length (l) and in this state, the fixing stand is held at the height, where the bathtub can be easily moved on the fixing stand wholly together with a stretcher. Next, when the bathtub is raised and set in an intermediate position B, the low use position of the bathtub is obtained. When the bathtub is further raised and the supporter is extended in the axial direction and set in an upper limit position C, the bathtub can be arranged in a high using position. At such a time, the fixing stand follows up the lifting operation of the bathtub and vertically moves between the intermediate position and upper limit position and a distance (h) between the bathtub flange surface and the upper surface of the fixing stand is not changed. Then, even when the bathtub is adjusted to any height, the objective person can be enough immersed into hot water in the bathtub and operation convenience is obtd.

Description

Detailed Description of the Invention (Field of Industrial Application) The present invention relates to an elevating bathing device suitable for use in bathing the elderly or physically disabled or for warming and moistening the dead. The present invention relates to a method for adjusting the height of a fixed base on which it is placed to a height that is easy to use.

(Prior art) Generally, bathing a disabled person is accompanied by many difficulties for the caregiver, so the bathtub is raised and lowered by a desired power mechanism, and the disabled person is placed on a stretcher while lying on his/her back. The patient was placed on a transport vehicle and placed next to a fixed stand installed in the bathtub, and the stretcher and the other body were transferred to the fixed stand, and then the bathtub, which was at a lower level, was raised to allow the bather to take a bath. In this way, a lift-type bathing device has already been proposed that allows a disabled person to take a bath without having to move.

In other words, this type of elevating type bathing device is shown in Fig. 4.
As illustrated in FIG.
The fixing base d is supported in a cantilevered state by the fixing base d, and one end of the fixing base d is supported on the device main body a, and the other end is supported on a support e inserted through the bottom surface b of the bathtub.

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 seat will be raised to the position where the bottom wall of the bathtub seat contacts the base d, but of course the height of the fixed base d is determined by the length of the support column e, unable to raise the
In the end, the height of the bathtub is determined at a predetermined position as shown in Figure 5, and therefore, depending on the height and physique of the caregiver (washer), the height of the bathtub b and fixed stand d may be too low or too low. If the bathtub is too high, you can lower the bathtub to the desired height, but it is not fixed. Since the height of the stand d remains unchanged, there are problems in use, such as not being able to fully immerse the subject in the hot water in the bathtub.

(Problems to be Solved by the Invention) The present invention has been made in view of the above-mentioned problems of the prior art.
The device has a column that penetrates the bottom wall of the bathtub in a liquid-tight state and supports a fixed base at the upper end, which is expandable and retractable in the axial direction, and the fixed base is brought in on a stretcher in a contracted state. It is configured to have a length that can be held according to the height,
The bathtub is raised and lowered independently from its lower limit position until it reaches an intermediate position corresponding to the stretcher carry-in height of the fixed platform, and after exceeding the intermediate position, until it reaches the upper limit position, By moving the fixed stand up and down by the movement of the bathtub, the bathtub and the fixed stand can be adjusted to the desired height that is convenient for the washing person, without changing the height difference between the flange surface of the bathtub and the top surface of the fixed stand. The purpose is to make it possible.

(Means for Solving the Problems) In order to achieve the above object, the present invention provides an elevating bathtub supported by an elevating mechanism, and a fixed bathtub supported by a column that liquid-tightly penetrates the bottom wall of the bathtub. A method for adjusting the height of an elevating bathing device comprising a stand, wherein when the bathtub is at the lower limit position, the length of holding the fixed stand corresponding to the height of carrying in the stretcher is the length when reduced. and the support is formed to be extendable in the axial direction so that it can be extended to the upper limit position of the bathtub, and the bathtub is raised from the lower limit position to a position corresponding to the stretcher carrying height of the fixed base. After reaching the 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. This is an attempt to provide a method of adjustment.

(Function) In the reduced state where the length of the column is the smallest, the column is held so that the fixing platform adapts 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 physically handicapped 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 there is an intermediate position where it is used at a low position, an upper position where it is used at a high position, and then a middle position where it is used at a high position. At any position from the upper limit position 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.

(Embodiments) Hereinafter, embodiments 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 lifting-type bathing device has a lifting mechanism driven by a motor or hydraulic pressure, hot water supply, water supply,
A drainage control mechanism, etc. is installed inside the device, and by operating a device main body with a lifting mechanism (not shown) installed on the floor 1, an elevating bathtub 2 connected to this device can be moved up and down by power. .

Inside the bathtub 2, a fixed stand 3 on which a human body can be placed is arranged so as to be housed therein.

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 l.

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 strut 4 is formed by fitting a first strut 4a and a second strut 4b so that they can slide freely in the axial direction, and this sliding portion 5 extends the upper part of the first strut 4a to a required length. , and at the center of the lower part of the second support 4b,
A recessed hole 4d into which the small diameter portion 4c fits is formed with a downward opening, and the small diameter portion 4c is slidably fitted into the recessed hole 4d.

Moreover, the minimum length of this support 4 when reduced is preset to a length that will hold the fixed base 3 in accordance with the stretcher carry-in height, and the maximum length is set in advance to the length required for the bathtub 2. , the length is set to match the height at the upper limit position, or an appropriate length longer than that.

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. 1, the column 4 is in a contracted state and is maintained at the minimum length.

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

In other words, a stretcher with a subject such as a disabled person lying on its back is placed on a transport vehicle, and the stretcher is placed sideways on the fixed base 3.
The fixed base 3 is held at a height that makes it easy to move it up.

After transferring the subject onto the fixed base 3 at the lower limit position (A) of the bathtub 2, the bathtub 2 is raised to the bottom wall 2a.
The inner surface 2c of the fixing base 3 comes into contact with the lower surface 3a of the fixing base 3, and 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.
It can be thoroughly crushed in the hot water inside.

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 the bottom 2a, so 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 Figure 3.

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

In addition, at this time, the fixed base 3 follows the vertical movement of the bathtub 2 and moves up and down between the intermediate position (B) and the upper limit position (C). ,
In addition, at any position between the repositions (b) and (c), the distance from the flange surface 2b of the bathtub 2 to the top surface of the fixed base 3 does not change, so the height of the above example Even if the adjustment is made, the subject can be fully immersed in the hot water in the bathtub 2.

In addition, when the bathtub 2 is lowered from the upper limit position (c), if the subject is placed on the fixed base 3, the subject and the fixed base 3
The support column 4 contracts due to the weight of the bathtub 2, or due to the weight of the fixed base 3 when no subject is placed thereon, and the fixed base 3 is lowered together with the bathtub 2, so that it can be placed in an intermediate position (b).

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

In addition, in the illustrated example, there are two pillars 4. Second both supports 4a
, 4b, but it may be formed by two or more pillars slidably fitted together, a pantograph, or any other arbitrary structure.

(Effects of the Invention) In the present invention, the heights of the bathtub and the fixed stand are adjusted as explained above, so that the fixed stand can be supported by a support that penetrates the bottom wall of the bathtub. has an arbitrarily set expansion and contraction stroke in the axial direction, and the lower limit position of the bathtub (
Except for (a), the height of the bathtub and the fixed stand can be adjusted without changing the distance between the bathtub flange surface and the fixed stand between the intermediate position (b) and the upper limit position (c). Therefore, the height can be adjusted to the user's preference for ease of use while keeping the person fully immersed in the hot water in the bathtub.
