Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to an elevating bathtub for bathing bedridden patients.

Conventional technology There is Utility Model Publication No. 61-24255 as a conventional technology, and the technology shown in this publication consists of a support that is inserted into the bottom of the bathtub, and a member that seals the support and the bottom in a liquid-tight manner using a slider and a flexible membrane. It is formed by

Problems that the invention attempts to solve In Utility Model Publication No. 61-24255, which was cited as a conventional technique,
Since the slider that fits into the column is connected to the bottom of the bathtub using a flat flexible membrane, the slider slides against the column with resistance when the bathtub moves up and down. A flexible membrane pulls up and down the moving body. In this configuration, tension is frequently applied to the flexible membrane, causing fatigue and breakage of the flexible membrane in a short period of time, resulting in poor durability of the flexible membrane.

Means for Solving the Problems The present invention solves the problems of conventional devices, and provides an elevating bathtub with a flexible cylinder that improves the durability of the mechanism that seals the column and the bottom wall of the bathtub. It is intended to.

That is, the present invention has the bottom wall 12 of the bathtub section 11 and the bottom wall 12.
A sealing mechanism part 1 that seals the pillar 3 that passes through the
consists of a sliding body 5 that is fitted onto the pillar 3 in a watertight manner, and a flexible cylinder 9 that is installed watertightly between the sliding body 5 and the bottom wall 12, and includes an upper cover 13a and a lower cover 13.
This is an elevating bathtub having a flexible cylinder, which is attached to the bottom wall 12 with the end b facing the sliding body 5, and the sliding body 5 is locked to the upper cover 13a and the lower cover 13b.

Further, the flexible cylinder 9 is installed between a back plate 10 attached to the sliding body 5 and an upper cover 13a attached to the bottom plate 12.

Embodiments Examples of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 shows a seal mechanism 1 of the present invention. A pedestal 4 is provided at the upper end of a column 3 erected on the base frame 2, and a sliding body 5 is fitted onto the middle of the column 3 in a watertight manner. A dust seal 6 and U gaskets 7a, 7b are held in grooves 8a, 8b, 8c carved in the slider 5 on the sliding surface between the support column 3 and the slider 5.

A flexible cylinder 9 made of a flexible member formed into a cylindrical shape is loosely fitted on the peripheral side surface of the sliding body 5, and the lower end of the flexible cylinder 9 is screwed together with a back plate 10 on the lower surface of the sliding body 5. The upper end of the flexible cylinder 9 is screwed onto the upper surface of the bottom wall 12 of the bathtub section 11 together with the upper cover 13a.

There is an upper cover 13a extending from the bottom wall 12 at a position where a portion of the upper surface of the sliding body 5 is covered, and has a slight gap 16 from the lower surface of the back plate 10 screwed onto the lower surface of the sliding body 5. A lower cover 13b extending from the bottom wall 12 is positioned below.

FIG. 2 shows the elevating bathtub of the present invention. An elevating mechanism section 14 for elevating and lowering the bathtub section 11 is mounted on the base frame section 2 . Furthermore, a device cover 15 is provided upright around the four circumferences of the base frame portion 2 .

FIG. 3 shows another embodiment of the present invention in which the lower end of the flexible cylinder 9 and the upper end of the back plate 10 are bonded to the upper cover 13a. Further, the flexible cylinder 9 may be formed into a bellows shape as shown in FIG.

Function When bathing a patient using the elevating bathtub of the present invention, the stretcher (not shown) on which the patient is placed is placed on the pedestal 4.
I'll put it on. Thereafter, the lifting mechanism section 14 is operated to raise the bathtub section 11. When the bathtub section 11 is raised, the pedestal 4 is immersed in hot water poured into the bathtub section 11, allowing the user to take a bath.

Next, the operation of the seal mechanism section 1 will be described.

When the bathtub part 11 is raised, the lower cover 13b provided at the penetrating part of the bottom wall 12 through which the support column 3 passes comes into contact with the back plate 10 of the sliding body 5 and pushes the sliding body 5 up.
When the bathtub section 11 is lowered, the upper cover 13a comes into contact with the upper surface of the sliding body 5 and pushes down the sliding body 5.

The pillar 3 and the sliding body 5 fitted on the pillar 3 are kept watertight by a dust seal 6 and U gaskets 7a and 7b, and the sliding body 5 and the bottom wall 12 are kept watertight. Watertightness is maintained by a flexible cylinder 9 installed between them.

When the bathtub section 11 is in the up/down state, the lower cover 13
After b and upper cover 13a come into contact with the upper surface of the slider 5 and the back plate 10, the slider 5 is pushed up or down, and the slider 5 slides up and down along the pillar 3.
When the above-mentioned bathtub section 11 is in an up-and-down state, even if a mutual horizontal positional shift or angular shift occurs between the support column 3 and the bottom wall 12, these shifts can be corrected by the flexible cylinder 9.
It is absorbed by the deformation of.

Effects of the invention Since the sealing mechanism is composed of a sliding body and a flexible cylinder, horizontal positional and angular deviations between the bottom wall and the column can be easily and easily absorbed by the vertical deformation of the flexible cylinder. . In contrast to the conventional structure in which a flat flexible membrane is installed horizontally and tension is applied to the flexible membrane in the horizontal direction, the flexible cylinder of the present invention is installed vertically, and the upper end of the flexible cylinder is Also, since the structure is such that the lower end is shifted in the horizontal direction, material fatigue is reduced and durability is significantly improved.

In addition, a lower cover and an upper cover are attached to the bottom wall with their tips having a predetermined interval to sandwich the sliding body, and the sliding body is pushed up and down by these lower cover and upper cover. Therefore, when the bathtub section moves up and down, no tension is applied to the flexible cylinder in the vertical direction, which prevents damage to the flexible cylinder and significantly improves durability.
