[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lift device, and more particularly to an improvement in a lift device used when a care-requiring person such as a physically handicapped person, an elderly person, or a sick person enters or exits a pool or a bathtub.

[0002]

2. Description of the Related Art As is well known, in a pool or a bathtub where a person requiring care, such as a physically handicapped person, an elderly person, or a sick person, may enter or leave, unlike a normal person who is a normal person. It is not enough just to have the facilities.

[0003] Therefore, it is assumed that a lift device for allowing a care recipient to enter or leave the pool or bathtub is provided in a pool or a bathtub where a care recipient may enter or leave. There are suggestions.

Among them, for example, the lift device shown in FIG. 7 is a so-called fixed lift device, in which the lower end is fixed to the bottom floor P1 of the water tank P such as a pool while the inner wall P2 of the water tank P is fixed. A column 1 standing up and down along with
A suspension seat 2 is provided at the upper end of the column 1 so as to be rotatable and moves up and down when the column 1 expands and contracts.

At this time, the column 1 is composed of a cylinder 1a, which is a lower member, and a rod 1b, which is an upper member.
Are set so as to protrude and retract, and the lower end of the cylinder body 1a constituting the lower end of the support 1 may be fixed to an inner wall P2 near the bottom floor P1 of the water tank P, though not shown.

The suspension seat 2 is configured such that an arm 2b for holding a seat 2a is a rod body 1 in the cylinder body 1 described above.
It is assumed that the boom 2c is hung on the distal end of a boom 2c having a base end connected to the upper end of the b. The boom 2c is turned by the rotation of the boom 2c as shown by a rotation arrow in the figure.

[0007] At this time, the base end of the boom 2c may be integrally connected to the upper end of the rod body 1b, or may be rotatably connected to the upper end of the rod body 1b. Is also good.

Therefore, according to the conventional lift device, when the care recipient is sitting on the seat 2a of the suspension seat 2, at least an attendant or the like forcibly moves the suspension seat 2, that is, By turning the support 1 around the center and extending and retracting the support 1, the care recipient can enter and exit the water tank P such as a pool.

Incidentally, although the expansion and contraction of the strut 1 is not shown, in many cases, the expansion and contraction is performed by a direct operation by an attendant of a driving mechanism disposed on a peripheral floor F or the like outside the water tank P or by remote operation. Set to get.

[0010]

However, in the above-described conventional lift device, for example, when a care-requiring person tries to get in and out of a water tank P such as a pool by himself / herself, there is a fear that this may become difficult. is there.

In other words, the above-mentioned lift device is configured so that the care-requiring person can enter and leave the water tank P by forcibly turning the suspension seat 2 by an attendant or the like. It is almost impossible to forcibly move the suspension seat 2 by itself while sitting on the seat 2a of the suspension seat 2.

Therefore, although not shown, for example, a handle and levers are attached to the column 1, and the levers are gripped by the caregiver who is sitting on the seat 2a, and then the force is applied thereto. A proposal can be made to allow the caregiver to turn around the column 1 on his own.

However, depending on how the levers are attached to the column 1, the seat 2a in a state where the care-requiring person is sitting may be in the water tank P.
It is only possible to pivot between above the outer peripheral floor F and above the water surface W indicated by the dashed line in the figure, i.e. to pivot around the column 1 at the so-called same level,
When the seat 2a in a state where the care recipient is sitting moves between the upper side of the water surface W and the water below the water surface W, that is, when the seat 2a moves up and down along the column 1 on the water tank P side, the seat 2a There is a possibility that the occurrence of a turning problem cannot be prevented.

The present invention has been made in view of the above-mentioned circumstances, and an object thereof is to enable a care-requiring person to easily enter and leave a pool or a bathtub by himself / herself.
An object of the present invention is to provide a lift device which is optimal for expecting an improvement in versatility.

[0015]

In order to achieve the above-mentioned object, the construction of a lift device according to the present invention is basically extended or contracted by an external operation while standing in a water tank or on a peripheral floor outside the water tank. In a lift device having a supporting column, and a suspension seat that is suspended at the upper end of the supporting column and is capable of turning while being extended and contracted while being pivotable, the first means includes:
It has an operation lever that allows the person sitting on the seat constituting the suspension seat to grip and perform input operation to rotate the suspension seat around the support column, and this operation lever is held on the support column so as to be able to move up and down It is supposed that it is lifted or lowered by a dedicated support standing on the peripheral floor or the like outside the water tank.

The second means has an operation lever for turning the suspension seat around the support column by a person sitting on the seat constituting the suspension seat and performing an input operation to rotate the suspension seat. Dedicated support column that has a fixed lever whose operation lever is positioned at an appropriate height outside the water tank, and a movable lever that can be moved up and down to the water tank side, and the fixed lever is erected on the surrounding floor outside the water tank. It is assumed that the movable lever is held by the above-mentioned column or a dedicated column so as to be able to move up and down while being held in a fixed state at the upper end of the column.

[0017]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described based on the illustrated embodiment. Even in the lift device according to the present invention, basically, the conventional lift device shown in FIG. Like the above, it is of a fixed type.

Further, as shown in FIG. 1, the lift device according to the present invention also has a bottom floor P1 of a water tank P such as a pool.
A pillar 1 that stands up and down along the inner wall P2 of the water tank P while being fixed to the water tank P, and a suspension seat 2 that is connected to the upper end of the pillar 1 and that rises and falls when the pillar 1 expands and contracts while being pivotable. It becomes.

At this time, the strut 1 and the suspension seat 2 are configured in the same manner as in the case of the conventional lift device. Therefore, the strut 1 and the suspension seat 2 are shown in each drawing except where necessary. Only the same reference numerals are given, and the detailed description is omitted.

Incidentally, when the column 1 is formed of a hydraulic cylinder, the so-called control fluid leaks out. For example, when the column 1 is formed of a hydraulic cylinder, the column 1 may be contaminated with oil due to oil leakage. This is advantageous in that it does not cause

As a result, as long as the support 1 has a predetermined verticality and the suspension seat 2 is not turned unnecessarily, its standing state may be freely set. As described above, the lower end of the column 1 is placed on the bottom floor P1 of the water tank P or the inner wall P of the water tank P adjacent thereto.
Instead of being fixed to 2, the column 1 may be erected only by the bracket structure B connected to the peripheral floor F outside the water tank P.

Next, the lift device according to the present invention is provided with an operation lever for turning the suspension seat 2 about the support column 1 by the care-requirer sitting on the seat 2a constituting the suspension seat 2 and performing an input operation. In the illustrated embodiment, the operating lever 3 is held by the above-mentioned column 1 so as to be able to move up and down, as shown by vertical arrows in the figure.

First, in the illustrated embodiment, the operating lever 3 is assumed to have a shape such as a steering handle in an automobile in plan view, as shown in FIG. It is assumed that a base 3a formed in a circular shape when viewed from the outside is interposed on the outer periphery of the cylinder body 1a constituting the column 1 (see FIG. 1).

At this time, the base 3a is connected to the outer periphery of the cylinder 1a so as to be able to move up and down so as not to be able to rotate in the horizontal direction, and is connected to a stopper provided at the upper end of the cylinder 1a. It is stated that 1c (see FIG. 1) prevents the cylinder 1a from falling off.

Incidentally, in the operating lever 3, the main body 3b connected to the base 3a has a part positioned on the water tank P side on the left side in the figure and a water tank P on the right side in the figure.
Although it is formed in a mode that is divided into a portion positioned outside of the car (see FIG. 2), it may be formed in a free mode as long as the input operation of the care recipient can be performed.

In the operation lever 3, it is needless to say that a grip 3c or the like having an appropriate shape may be continuously provided on the main body 3b.

Therefore, in the lift device according to the present invention, the care-requirer sitting on the seat 2a of the suspension seat 2 uses the operating lever 3 held on the support column 1 so as to be able to move up and down. Thus, the user can turn himself or herself around the seat 2a.

At this time, it goes without saying that the suspension seat 2 is pivoted by the rotation of the boom 2c as shown by the rotation arrow in the drawing.

Although not shown, the column 1 is expanded or contracted by a direct operation by an attendant or the like of a driving mechanism disposed on a peripheral floor F or the like outside the water tank P, or by remote operation.
When the seat 2a in a state where the care-requirer is sitting moves up and down between the upper side of the water surface W and the water below the water surface W, the care-requirer sitting on the seat 2a holds the operation lever 3 described above. As a result, the seat 2a turns, and the care-requiring person moves to the inner wall P of the water tank P.
2 can be prevented from occurring in advance.

In view of the above, when the seat 2a in a state where the care-requirer is sitting moves up and down on the water tank P side, the operating lever 3 can be used as long as the care-requirer sitting on the seat 2a can grasp it. 3 and FIG. 4, it may be held up and down by a dedicated column 4 erected on the peripheral floor F outside the water tank P, as shown in FIGS.

At this time, the dedicated support column 4 is formed so as not to be easily bent by an input operation performed by the care-requiring person. At times, it will be formed so as not to be easily bent.

Also, the main body 3b of the operation lever 3,
In particular, the main body 3b positioned on the left side of the water tank P in the figure is arranged on the outer peripheral side of the column 1 so that the column 1 is present inside (see FIG. 4).

In this embodiment, it is assumed that a plurality of dedicated columns 4 are provided, and a plurality of bases 3a of the operation lever 3 are connected to each dedicated column 4, respectively. By being connected by the connecting rod 4a, it is possible to prevent the operation lever 3 from rotating in the horizontal direction with respect to the dedicated support column 4 without taking any special measures.

In addition, instead of being provided on the peripheral floor F outside the water tub P, the dedicated support 4 is connected to the inner wall P2 of the water tub P or fixedly attached to the support 1 (not shown). May be held.

By the way, as for the operating lever 3, the case where the part positioned on the water tank P side and the part positioned outside the water tank P are integrated has been described above, but the present invention is intended. In other words, as long as the operation lever 3 can be rotated by the person sitting on the seat 2a constituting the suspension seat 2 and the input operation is performed, the suspension seat 2 can be pivoted about the support column 1. Is a water tank P
The part arranged on the side and the part arranged outside the water tank P may be separated.

That is, the operation lever 3 shown in FIGS. 5 and 6 has a fixed lever 31 which is positioned at an appropriate height outside the water tank P, and a vertical lever which is positioned on the water tank P side in the figure. And a movable lever 32 that can be moved up and down.

While the fixed lever 31 is fixedly held at the upper end of the above-mentioned dedicated column 4 erected on the peripheral floor F outside the water tank P, the movable lever 32 is fixed to the above-mentioned dedicated column 4. It is said to be held up and down.

In this embodiment, it is needless to say that the fixed lever 31 and the movable lever 32 may each be provided with a grip 3c.

Therefore, according to this embodiment,
The movable lever 32 that is easily wettable can be configured differently from the fixed lever 31 that is hardly wettable. As a result, for example, a configuration that has water resistance and is easy for a care-requiring person to grasp is provided. This is advantageous in that it can be selected.

5 and 6, the movable lever 32 is held by the dedicated support column 4 and can be moved up and down. However, from the intended point of this embodiment, the movable lever 32 is (Not shown), it may be held by the above-mentioned column 1 so as to be able to move up and down.

As described above, the column 1 constituting the lift device according to the present invention is erected in a water tank P such as a pool, but from the point of view of the present invention, the column 1 is The control lever 3 may be erected on the peripheral floor F serving as the upper end. In this case, the operation lever 3 also functions in the same manner as described above.

[0042]

As described above, according to the present invention, in a lift device having a suspension seat which is lifted up and down by expansion and contraction of a support column while being pivotally supported by a support column, a person sitting on a seat of the suspension seat operates the lift device. Since it is assumed that the hanging seat can be turned by grasping the lever and performing an input operation, the care recipient sitting on the seat of the hanging seat is, for example, held up and down on a column, or a peripheral floor outside the water tank. By using the operating lever held on a dedicated support column standing upright or the like, it becomes possible for the user to turn himself or herself around the support column together with the seat without the assistance of an attendant or the like.

According to the present invention, all or a part of the operation lever is held by the above-mentioned column or the dedicated column so as to be able to move up and down. In addition, since the care-requiring person grips the operation lever, it is possible to prevent in advance the occurrence of a problem in which the seat turns and the care-requiring person contacts the inner wall of the aquarium.

As a result, according to the present invention, the care-requiring person can easily enter and leave the pool or bathtub by himself / herself, and is therefore most suitable for expecting improvement in versatility.
