Description

[Detailed Description of the Invention] [Technical Field] The present invention provides an elevating type bathing device for a physically handicapped person that ensures a seal between an elevating type bathtub and a support column for supporting a fixed base that passes through the bottom surface of the elevating type bathtub. Regarding.

[Conventional technology and its problems]

In general, there are many difficulties when bathing a disabled person. An elevating bathing device has been proposed in which the person with a physical disability can take a bath without having to move, by placing the person on a fixed stand, transferring the stretcher to the fixed stand, and then raising the bathtub to bathe. .

This type of lift-type bathing device supports the bathtub in a cantilevered manner with respect to the device body that houses the water heater, etc., and also inserts one end of the fixing base into the device body and the other end through the bottom of the bathtub. It is designed to be supported by each pillar. Therefore,
The part where the column passes through the bottom of the bathtub must be sealed liquid-tight, and conventionally the column has been covered with a waterproof column cover such as a rubber bag.

For this reason, in conventional lift-type bathing devices, when the bathtub is in the raised position, the waterproof column cover is sagging inside the bathtub, which reduces the internal volume of the bathtub, and also makes it difficult for disabled people to take a bath. This has the disadvantage that it gets in the way, and that the waterproof column cover deforms each time the bathtub is moved up and down, resulting in severe wear and tear on the waterproof column cover.

The present invention eliminates the above-mentioned drawbacks, and the column that supports the fixing base that is located in the elevating bathtub and is maintained at the stretcher carrying height has a ring-shaped sealing material at the portion that penetrates the bathtub. To provide an elevating type bathing device which is sealed and thereby reliably prevents water from being washed away from a part through which a support is inserted as the bathtub is ascended and descended.

[Means for solving problems]

In order to achieve the above object, the present invention provides an elevating bathtub,
a fixed base supported by a column that passes through the bottom of the bathtub; a slider that is slidable in the axial direction and fitted to the column of the fixed base in a liquid-tight manner; and the slider and the bathtub. The main feature is that the pillar is inserted into the bottom surface of the support column, and a flexible membrane is fixed to the bottom surface of the support column.

[Effect]

According to the present invention, since the sliding contact portion of the slider that is slidably fitted to the support is sealed, there is no need for a waterproof support support cover, which was required in the past, and the slider is fitted with a flexible membrane. Since it is attached to the bottom of the bathtub, it can be used even if the bathtub is tilted due to the weight of the hot water, or if the bathtub is shaken or tilted when going up and down, or if the support column is tilted due to the weight of the bather and stretcher on the fixed base. Even if the slider is in contact with the slider, the effect will not reach the slider, and the slider will always be able to maintain a good sealing condition without tilting with respect to the column.Furthermore, the seal at the sliding contact part of the slider should be a seal such as an O-ring. It can be easily realized using a material, and if the number of sealing materials used is two or more, excellent effects such as more reliable sealing can be achieved.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings. Figures 1 and 2 are front views showing the state when the bathtub is raised and lowered, respectively, of an embodiment of the elevating type bathing device of the present invention, and Figures 3.4 and 1.2 are respectively shown in Figures 1 and 2. FIG. 3 is an enlarged longitudinal cross-sectional view showing a sealing mechanism portion of the illustrated strut.

In Fig. 1.2, an elevating type bathing device 1 is constructed such that a bathtub 4 is connected to a device main body 3 installed on a floor 2 and equipped with hot water supply, water supply, drainage control mechanisms, etc., with two cantilevered forks 5 on both sides. The structure is such that the bathtub 4 is raised and lowered together with the fork 5. The elevator groove (not shown) of the fork 5 is 1. Device body 3
In this embodiment, it is configured to be driven by hydraulic pressure. A fixed stand 6 constructed using a stainless steel frame is disposed inside the bathtub 4. The distal end of the fixing base 6 is integrally connected to an arm 7 extending in an inverted shape from the side surface of the device main body 3, and the tip end is inserted through the bottom of the bathtub 4 and attached to the floor 2. It is supported by fixed columns 8. The length of this support 8 and the vertical length of the arm 7 are approximately equal, and the bathtub 4 can be moved up and down between the lower end and the upper end of the support 8.

Here, a sealing mechanism 9 shown in FIG. 3 is provided at a portion where the support column 8 passes through the bottom surface of the bathtub 4.

This sealing mechanism 9 includes a rubber membrane 1 as a flexible b1g having a size matching a large diameter hole lO formed on the bottom surface of the bathtub 4.
1, a slider 13 that fits into a hole 12 with a larger diameter than the support post 8 formed in the center of the rubber membrane 11 and is slidably fitted to the support post 8, and sliding movement of the slider 13 and the support post 8. It is composed of a sealing material 14 such as an O-ring that seals the part at two places.

Reference numeral 15 denotes a ring depression member for screwing the outer peripheral portion of the rubber membrane 11 to the opening edge of the hole IO, and the rubber membrane 11 is tightened by a bolt 16 that is pushed through the opening edge. Reference numeral 17 denotes a ring depression member for screwing the inner circumferential portion of the rubber film If to the slider 13, which is passed through and tightened by a bolt 18 that is screwed into the slider 13.

In this way, the sealing mechanism 9 configured as described above uses the sealing material 14 to seal the sliding contact portion of the slider 13 that is slidably fitted to the support post 8, so that the waterproof support support cover that is conventionally required is not required. It can be done. Furthermore, since the slider +3 is attached to the bottom surface of the bathtub 4 via the rubber membrane 11, even if the bathtub 4 is tilted due to the weight of hot water, for example, as shown in FIG. 4, the slider 13 will not be affected. Therefore, the sliding contact portion between the slider 13 and the support column 8 can always be kept in a good sealing state. Furthermore, since the sealing material 14 is provided at two locations, upper and lower, on the inner periphery of the slider 13, safety against seal failure of one of the sealing materials 14 can be ensured.

〔Effect of the invention〕

As explained above, according to the elevating bathing device 1, the sliding contact portion of the slider 13 that is slidably fitted to the support post 8 is sealed, so the waterproof support support cover that is conventionally required is unnecessary. In addition, since the slider 13 is attached to the bottom of the bathtub 4 via the rubber membrane 11, even if the bathtub 4 is tilted due to the weight of the hot water, or even if there is vibration or inclination when the bathtub is raised and lowered, the slider 13 can be attached to the bottom of the bathtub 4 through the rubber membrane 11. Even if the support column is tilted due to the weight of the bather and stretcher, the effect will not extend to the slider 13, and the slider 13 will not be tilted with respect to the support column 8 and a good sealing state can be maintained. Furthermore, sealing of the sliding contact portion of the slider 13 can be easily achieved using a sealing material 14 such as an O-ring, and if the number of sealing materials 14 used is two or more, a more reliable seal can be achieved. is possible.
