Description

  The present invention relates to a simple bathtub, and more particularly to a temporary simple bathtub for one person.

In recent years, various ideas have been made to improve the quality of life of people who need assistance (for example, elderly people). In particular, when a person requiring assistance takes a bath, it has been practiced that the assistant holds the body of the person requiring assistance and puts it in a bath tub that is permanently installed in the bathroom. In addition, when the bathroom floor is wet, the caregiver holding the person who needs assistance may slide his / her foot.
In order to solve such problems, it has been proposed that a door is provided on a part of the wall of the bathtub so that a person requiring assistance can enter the bathtub without overcoming the wall.
The bathtub of patent document 1 is a permanent thing fixed to the floor of a bathroom, has a rectangular surrounding wall seeing from the upper part, cuts out the width direction intermediate part of the long side of a rectangle among this surrounding wall, and an entrance / exit Is provided.
A pair of vertical grooves are formed at the mouth edge of the doorway, and both ends are fitted into these grooves, and the open / close door is inserted into the nectar.
The open / close door is composed of three partition plates (upper plate, middle plate, and lower plate for partition).
The bathtub of patent document 2 is a box-shaped thing of the upper end opening put on the floor of a bathtub, and consists of a bathtub main body, a rotary door, and a chair.
The bathtub body is formed by standing up a rear plate from the rear side of the square bottom plate, and a pair of side plates with the rear end connected to the rear plate from both left and right sides of the bottom plate, and forms an entrance between the front portions of the side plates. doing.
The revolving door covers the doorway, and has one end in the left-right direction pivoted (referred to as being connected by a hinge) to the front end of one side plate.
The chair is arrange | positioned at the rear part of the baseplate of the said bathtub main body.

I can't. Therefore, after a person requiring assistance enters the bathtub, the doorway is closed with a door, and then hot water is poured into the bathtub. However, it takes time to put hot water in a permanent bathtub to a predetermined water level. Especially in winter, the person who needs to take off clothes is exposed to cold before the hot water in the bathtub reaches a predetermined water level, which may cause physical condition to be lost.
The patent applicant has intensively studied these problems, and has come to consider that the bathtub into which a person requiring assistance must enter should not have an excessively large internal volume and can be filled with hot water in a short time.
In the thing of patent document 2, the front surface of the side surface of a bathtub is an inclined surface to the rear upper direction, and the rotary door is attached along this inclined surface. However, there is a large space on the upper side of the thigh of the person requiring assistance or the lower side of the chair while the person requiring assistance is sitting on the chair.
Furthermore, the present applicant has recalled the need to adjust the internal volume and to quickly set the bathtub by using a bag support that supports a flexible bathtub bag that accommodates the body of a bather in a sitting position from the outside.
The idea of using a bathtub bag for bathing a person who needs assistance exists in Patent Document 3, for example.

FIGS. 12-14 has shown the simple bathtub of 8th Embodiment of this invention. The simple bathtub of the present embodiment includes a bathtub bag 60 that is a bathtub body, a bag support 50, and a seat 58.
The bathtub bag 60 is a bag-like member with an upper surface opening, and includes a bottom surface portion 60a, a rear surface portion 60b, a pair of left and right side surface portions 60c, and a front surface portion 60d. An opening 62 is formed in the front surface portion 60d from the upper end to the vicinity of the lower end. In the illustrated example, the opening 62 is provided with an opening / closing means 63. Although the illustrated opening / closing means is formed as a fastener, it may have any structure as long as it has a waterproof function.
The bathtub bag 60 may be formed from a sheet that is a flexible and waterproof material (such as vinyl chloride resin). For example, the two sheets forming the pair of left and right side surface portions 60c of the bathtub bag 60 and the one sheet extending from the front surface portion 60d through the bottom surface portion 60a to the rear surface portion 60b may be formed.
The bag support 50 is formed by a pair of left and right side support plates 52 and a joint plate 54.
The side support plate 52 is in contact with the side surface portion 60c of the bathtub bag 60 and supports the side surface portion 60c so as not to bulge outward. The side support plate 52 is fixed to the side surface portion 60c.
The illustrated side support plate 52 includes a first horizontal plate portion 52c, a second horizontal plate portion 52d, and a third horizontal plate portion 52e respectively from the upper end portion, the vertical middle portion, and the lower end portion of the first vertical plate portion 52a. While projecting forward, the front end portions of these horizontal plate portions are connected by the second vertical plate portion 52b. However, these configurations can be changed as appropriate. The bag support 50 is formed to maintain an upright state by bringing at least the lower end surfaces of the pair of side support plates 52 into contact with the floor surface.
The joint plate 54 extends in the left-right direction on the rear side of the bathtub bag 60, and both ends thereof are connected to the side support plate 52.
In this connection place, a hinge 57 joined to the inner surface of the side support plate 52 is attached to the front edge of both end portions of the joint plate 54 in the longitudinal direction. The joint plate 54 is a thick plate material, and the end surface of the joint plate is in contact with the inner surface of the side support plate 52 in the state shown in FIG.
Accordingly, the joint between the joint plate 54 and the side support plate 52 changes so that the angle between the two plates changes from a right angle to an acute angle, as shown in FIGS. 13A to 13B. It is formed so as not to change from an obtuse angle to an obtuse angle.
In addition, the joint plate 54 is cut at the intermediate portion in the longitudinal direction and divided into two half plate portions 55, and the end portions of the respective half portions are connected by hinges 57 at this portion. The hinge 57 connects the front edges of the end portions of the connecting portions, and the end faces of the half plate portions 55 abut each other in the state shown in FIG.
Therefore, as shown in FIGS. 13A to 13B, the connecting portion between the half plate portions 55 can be refracted from the linear state to the front side (tub bag 60 side). It is formed so as not to be deformed from the linear state to the rear side (the side opposite to the bathtub bag 60).
Hereinafter, for convenience of description, a connection portion between the joint plate 54 and the side support plate 52 and a connection portion between the half plate portions 55 are referred to as a refraction line 56.
The action of these refraction lines 56 prevents the bathtub bag 60 from expanding in the horizontal direction while resisting the water pressure in a state where hot water is stretched in the bathtub bag 60 in the state shown in FIG. When the hot water in the bathtub bag 60 is drained, it can be folded inward.
In addition, the structure of the example of illustration is only a suitable example, and as long as there exists the same effect | action, what kind of structure may be sufficient as it.
In the present embodiment, as the joint plate 54, a first joint plate 54A, a second joint plate 54B, and a third joint plate 54C are provided. However, these structures can be changed as appropriate.
The first joint plate 54A is installed between the upper ends of the first vertical plate portion 52a. The first joint plate 54A serves as a backrest for the user who is taking a bath to lean on the back.
Further, the second joint plate 54B is constructed between the second horizontal plate portions 52d and the third horizontal plate portions 52e, and the third joint plate 54C is further provided in the lower half of the first vertical plate portion 52a. It is erected between the parts. The second joint plate 54B and the third joint plate 54C of the embodiment are formed at the same height, and also serve as support means for a seat plate 58a described later. The lower end surfaces of the second joint plate 54B and the third joint plate 54C are formed flush with the lower end surface of the side support plate 52, and are provided so as to be able to contact the floor surface.
In the present embodiment, the pedestal 58 includes a seat plate 58a and support legs 58b suspended from the lower surface of the seat plate, and the seat plate 58a is bridged between the second joint plate 54B and the third joint plate 54C. In addition, the support leg 58b is brought into contact with the lower surface of the floor surface. However, these configurations can be changed as appropriate. For example, when the user's weight can be sufficiently supported only by the second joint plate 54B and the third joint plate 54C, the support leg 58b may be omitted. Although the support leg 58b is formed in the support cylinder for weight reduction, forms other than a cylinder (support bar) may be sufficient.
FIG. 12A shows a longitudinal sectional view of the present embodiment. The bottom surface portion 60a of the bathtub bag 60 is as wide as a footrest. The rear surface portion 60b extends to the front surface of the first joint plate 54A along the front surface of the second joint plate 54B and the upper surface of the seat plate 58a. This form corresponds to the lower recessed portion DL referred to in the first embodiment when viewed from the side.
