Description

[Detailed Description of the Invention] The present invention relates to an elevating bathing device that allows a bather to be safely raised and lowered into a bathtub with a deep bottom.

Generally, elderly people, disabled people, and patients require a caregiver to take a bath in a cleaning bathtub or a therapeutic bathtub.In order to reduce the burden on the caregiver, a lift bath is used to move the bather in and out of the bathtub. Equipment is essential. Conventional lift-type bathing devices carry the bather on a stretcher to the edge of the bathtub, transfer the bather onto a lift stand waiting outside the bathtub, and drive the lift stand after transfer.
It is designed to transfer the bather into the bathtub along with the elevator platform.

However, this type of conventional lifting bath device
An inverted U whose lifting platform has the same length as the depth of the bathtub.
It is attached to one end of the letter-shaped pillar, and this inverted U
The structure is such that a letter-shaped support straddles the edge of the bathtub and moves up and down inside or outside the bathtub. Therefore, when the elevating platform rises, the top of the support moves from the bathtub mounting surface to the two sides of the bathtub. The height is about twice as high, so there are problems in applying it to places with low ceilings, and it is dangerous for caregivers and the like to enter the space in which the pillars can be raised and lowered.

The present invention eliminates the above drawbacks, and by forming two rows of hoistways on supports installed on the side of the bathtub and connecting these hoistways at the top of the support, one hoistway can be connected to the other. The platform is configured so that the platform raised outside the bathtub can be lowered into the bathtub along the other hoistway, thereby keeping the supports forming the hoistway of the platform at a minimum height. The purpose of the present invention is to provide an elevating type bathing device that allows for

In order to achieve this objective, the present invention includes a pillar installed on the side of a bathtub, two rows of hoistways formed on the pillar and located on the inside and outside of the bathtub, respectively, and a platform for carrying a bather. , a lifting platform that can be freely raised and lowered one row at a time on the two rows of hoistways, a lifting mechanism that drives the lifting platform up and down, and a lifting platform that moves up and down one of the two rows of hoistways. The gist of the system is that it includes a switching mechanism that transfers the shaft to the other hoistway side after it has become tight.

According to the present invention, two rows of hoistways are formed on the pillars installed on the side of the bathtub, and the hoistway on which the bather is placed is raised along one of the hoistways located outside the bathtub. Since the structure is such that when it reaches the top of the rise, it is moved to the other shaft side, the support can remain fixed and only the shaft can be moved up and down, allowing the bather to easily move from the inside of the bathtub to the outside and from the outside to the inside. This allows it to be used even in rooms with low ceilings, as long as there is space for the top of the support that is slightly higher than the edge of the bathtub, and since the support does not go up or down, it is possible to perform assistance work even right above the support. can be,
This provides excellent effects such as reducing restrictions on assistance work.

Embodiments of the present invention will be described below with reference to the drawings. Figures 1 and 2 are a plan view and a front view, respectively, showing an embodiment of the elevating type bathing device of the present invention, and Figures 3 and 4 are plan views showing enlarged main parts of Figures 1 and 2, respectively. and a partially cutaway front view.

In Figures 1 and 2, the lift-type bathing device 1 has a bottom surface with two shallow and deep steps in consideration of underwater walking training.
A bathtub 2 having a letter-shaped plane, a column 3 fixed to the side of one longitudinal end of the bathtub 2, and a lifting platform with a stretcher that moves up and down along two rows of hoistways 4 and 5 formed on the column 3. 6 and elevating mechanism 7 of elevating platform 6
It is roughly composed of a diversion mechanism 8, etc.

The support column 3 is hollow, and the pivot post 9 passes through the hollow portion. The rotating post 9 constitutes a main part of the turning mechanism 8 together with a cap 9a fixed to the top thereof, and a chain 12 is driven by the power of a forward/reverse motor 11 via a speed reducer 10.
is rotated in the forward and reverse directions. Further, a wire rope 13 whose one end is tied to the roller-equipped base 6a of the lifting platform 6 is inserted through the inside of the rotation post 9, and the other end of the wire rope 13 is connected to the base 6a with a roller of the elevator platform 6. It is connected to a wire drum 16 in the lifting mechanism 7 via pulleys 14 and 15. The wire drum 16 is rotated in forward and reverse directions by the power of a forward and reverse motor 18 via a speed reducer 17 .

Incidentally, on the side surface of the support column 3, there are rail-shaped hoistways 4, 5 held by four rollers 19 of the base 6a.
are formed in two rows, but these hoistways 4 and 5
can be communicated by a cap 9a provided on the top of the pivot post 9. That is,
The lower end surface of the cap 9a is in contact with the upper end surface of the support column 3, and a rail-shaped communication path 20 formed on one side of the cap 9a allows for lifting or lowering of either one by rotating the cap 9a at an appropriate angle. The configuration is such that it is connected to line 4 or 5.

When taking a bath, a stretcher (not shown) carrying a bather is placed next to the elevator platform 6 at the position indicated by the dashed line in FIG. Next, the caregiver transfers the bather from the stretcher onto the stretcher 21 of the lifting platform 6.
After the transfer, the forward/reverse rotation motor 18 is started to rotate forward in order to drive the lifting mechanism 7. As a result, the wire rope 13 is wound around the wire drum 16, and the base 6a of the lifting platform 6 rises along the hoistway 4 outside the bathtub 2. When the base 6a finishes moving up the hoistway 4 and enters the communication path 20, the forward/reverse motor 1
8 is stopped, and the forward/reverse rotation motor 11 in the turning mechanism 8 is instead started to rotate forward.

When the forward/reverse motor 11 is activated, the rotating post 9 rotates, and thereby the lifting platform 6, which has been raised to the top of the rotating post 9, rotates from the outside of the bathtub 2 to the inside. When the lifting table 6 rotates to a position directly above the bathtub 2, the forward/reverse rotation motor 11 stops, and instead, the forward/reverse rotation motor 18 in the lifting/lowering mechanism 7 is started to rotate in reverse.

At this time, the communication path 20 formed in the cap 9a
is connected to the other hoistway 5 of the rotating post 9, so the base 6a of the hoist 6 moves from the communication path 20 to the hoistway 5 and descends inside the bathtub 2 as the wire drum 16 rotates. do. Lifting platform 6 is support 3
When the elevator descends to the lowest end of the bathtub, the forward/reverse motor 18 stops, and when the driving of the elevator platform 6 is completed, the bather on the stretch bench 21 of the elevator platform 6 is moved to the bottom of the bathtub as shown by the dotted line in FIG. It will be in a state where it has sunk sufficiently into 2.

In this way, the lifting platform 6 ascends along the hoistway 4 on one side of the column 3, rotates on the upper part of the pivot post 9, and then descends along the hoistway 5 on the other side of the column 3. In order to enter the bathtub 2, there is no need to move the pillar 3 and the rotating post 9 up and down, and the lifting platform 6
Only the parts move up and down along the pillar 3. Therefore, unlike traditional lifting bath equipment, in any case,
The movable part does not move to a location higher than the cap 9a, and as a result, it is possible to sufficiently reduce the size in the height direction.

Note that the elevator platform 6 inside the bathtub 2 can be moved out of the bathtub 2 in the reverse order of the previous operation.

In addition, in the above embodiment, as a bather,
The user is not limited to the elderly, physically disabled, or patient, but may also be a healthy person, and a chair or the like may be provided on the elevator platform 6 instead of the stranger 21.

Elevating bathing device 31 shown in FIGS. 5 to 7
is constructed by installing a seat 32 on a lifting platform 6. However, unlike the lifting type bathing device 1 shown in the above embodiment, the pillar 3 is provided separately from the bathtub 2. The material itself can be made of a reinforced plastic material or the like that does not require material strength. This is because there is no need for a part to fix the support column 3 on the bathtub 2 side, and in addition to this manufacturing cost reduction effect,
It is also applicable to the existing bathtub 2 and has great effects. Further, since the support column 3 is separate from the bathtub 2, it is possible to leave the bathtub 2 and store the other parts of the elevating bathing device 31 in an appropriate location.

As explained above, according to the elevating type bathing device 1 having the above structure, two rows of elevating passages 4 and 5 are formed on the pillar 3 erected on the side of the bathtub 2, and the elevating and descending passages 4 and 5 are formed so that a bather can be placed on the elevating and descending baths. The platform 6 is raised along one hoistway 4 located outside the bathtub 2, and when it reaches the top, it is moved to the other hoistway 5 side. It is possible to easily move the bather from the inside to the outside and from the outside to the inside of the bathtub 2 by raising and lowering only the platform 6, and there is a space in which the top of the support column 3, which is slightly higher than the edge of the bathtub 2, can fit. , it can be used even in rooms with low ceilings, and since the pillar 3 does not go up and down, the pillar 3
Assisting work can be performed even directly above the vehicle, reducing restrictions on assisting work.
