Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to an elderly person or a physically handicapped person who has a deteriorated walking function, and a healthy person who encounters some kind of accident such as a traffic accident or an accident while working, and temporarily loses his legs. The present invention relates to a bathtub which allows a disabled person to take a bath relatively easily without the need for nursing care and to facilitate the assistance of these persons when taking a bath.

[0002]

2. Description of the Related Art Conventionally, there are various types of bathtubs of different types and sizes, but it is generally assumed that adults and children (hereinafter referred to as healthy persons) who have a healthy body can comfortably take a bath. It has a structure.

FIG. 17 shows the structure of the bathtub B.
Most of the bathtubs B have a height of 450 to 600 mm, and the height from the floor surface F to the edge of the bathtub B is set so that the bathtub B can easily enter and exit the bathtub B by straddling the edge when bathing. But,
In many cases, the position of the bathtub B is set lower than the floor F so that the height is about below the knee, that is, about 400 mm.
Therefore, a healthy person can easily enter and leave the bathtub by straddling this edge.

[0006] However, even if the height of this rim is a height that a healthy person can comfortably straddle, it cannot be easily straddled by a physically handicapped person or an elderly person who has a disabling leg. It puts a heavy burden on the legs and hands and is dangerous, and it is often impossible to take a bath without a caregiver.

For this reason, it is necessary for a caregiver to help a physically handicapped person or an elderly person who has a leg difficulty in taking a bath. Even if the caregiver holds a bather and takes a bath, It is necessary to support all or most of the body weight, and wet tile floors and resin board floors are slippery and cannot be easily assisted by anyone.

Further, the present invention is not limited to persons with physical disabilities and elderly people who have leg problems. For example, a healthy person may experience some accident such as a traffic accident or an accident while working, and the leg may be temporarily disabled. It is the psychology of the person who wants to take a bath without asking as much help as possible, that is, without disturbing others.

Further, even when assistance is required, it is desirable to reduce the burden on the assistant as much as possible, and a person who has a disability in his / her legs also desires to do so.

Although tools such as handrails and footrests for hanging on the edge of a bathtub are commercially available, it is required to have some strength in the legs and waist when using this kind of tool, and the helper's help Although it is useful as an auxiliary tool used in combination with, it is not suitable for use by people with impaired walking function, and there are many risks. In addition, it is not only unnecessary for a bather who relies heavily on assistance, but also an obstacle.

In order to solve these problems, recently, an opening for opening and closing a bather is formed on the side surface of the bathtub, and an openable door is attached to this opening so that the bather can enter and leave the bathtub. There has been proposed a bathtub having a structure that does not need to greatly straddle the edge of the bathtub (JP-A-3-26221, JP-A-1-170457, and JP-A-2-51608).

[0010]

Incidentally, in the bathtub of this kind of structure, a method is adopted in which the gap between the door of the entrance and exit and the bathtub is stopped by a sealing material such as packing or compression seal.
There is a problem that the hot water easily leaks from this gap due to deterioration due to the expansion and contraction of the sealing material for a long period of time, door misalignment and door deformation, and thermal deterioration of the packing due to hot water temperature, resulting in poor durability.

Further, it is necessary to firmly close the door to the bathtub and lock the door with a handle or the like while compressing the sealing material, but this operation is a considerable force for the physically handicapped person or the elderly. There is a problem such as requiring.

[0012] Furthermore, it is important that the entrance to the bathtub is narrow, and it is extremely difficult for a caregiver to hold the bather in and out of the bathtub. Moreover, the direction in which the bather is held is limited, and the caregiver to be held. There is also a problem that the number of people is limited, which puts a great burden on the caregiver.

The present invention has been completed in view of the above technical problems, and some accidents such as a traffic accident or an accident during work of an elderly person and a physically handicapped person whose walking function is deteriorated, and a healthy person. In addition, bathers, etc. who have temporarily lost their legs and feet can easily get in and out of the bath without the need for care.
It is possible to take a bath in a comfortable posture, and when a senior citizen who is unable to walk or a physically handicapped person goes into or out of the bathtub, caregivers or caregivers should be able to take care or assistance safely in a comfortable posture. In addition, it is an object of the present invention to provide a bathtub which is easy to supply and which is easy to supply without the leakage of the bathwater in the bathtub.

[0014]

In order to achieve the above-mentioned object, the bathtub according to the present invention is formed so that at least a bathing person's entrance / exit portion in the peripheral side surface portion of the bathtub body is formed low. The bathtub frame is attached to the upper end of the side surface so as to be vertically expandable and contractible.

The bathtub of the present invention will be described in more detail as follows. The size and plane shape of the bathtub according to the present invention are not particularly limited, but the bather can dip the shoulders into the hot water in a comfortable position, and the wasteful space is limited as much as possible for convenience of installation and bathing. It is desirable that the plan view has a rectangular shape, an elliptical shape, or a circular shape in consideration of the ease of construction and the ease of use of the structure of the bathtub frame that can be expanded and contracted up and down without waste of hot water.

The bath is made of synthetic resin, rubber, FRP, or metal or ceramic depending on the location.

In the present invention, the entrance / exit location of the bather is formed low on the peripheral side surface of the bathtub body, and the bathtub frame is attached to the upper end portion of the side surface which is the entrance / exit location of the bather so as to be vertically expandable and contractible. Anything that is already available may be used.

That is, in the case of this bathtub, the side surface portion of the peripheral side surface portion of the bathtub body corresponding to the entrance / exit location of the bather is formed low, and the other peripheral side surface portion is formed at a predetermined height. Is configured to cover the person.

On the other hand, a bathtub frame is attached to the upper end portion of the side surface which is the entrance and exit portion of the bather so as to be vertically expandable and contractible. After the bather enters the bathtub, the vertically expandable bathtub frame is moved upward. It can be extended and fixed, and then heated in the bathtub.

Further, in the present invention, it is also advantageous that the peripheral side surface portion of the bathtub body is formed low, and the bathtub frame is attached to the upper end portion of the peripheral side surface portion so as to be vertically expandable and contractible.

In this bathtub, the entire peripheral side surface of the bathtub body is formed low, and a bathtub frame is attached to the upper end portion of the bathtub frame so that the bathtub frame can extend and contract vertically. It is sufficient to extend the bathtub frame upward, fix it at a predetermined position, and then supply hot water into the bathtub.

In the present invention, when a stool is installed in the body of the bathtub, a bather can sit on the stool and take a bath, and can take a bath in a comfortable posture. This is beneficial because it significantly reduces the labor of caregivers and caregivers.

That is, a seating surface (stool) is placed inside the bathtub body.
Is formed so as to project upwards, and the peripheral side surface inside the bathtub body has a height (e.g., about half the height below the knees of an adult) where there is no resistance for physically handicapped persons or elderly people with impaired walking function to straddle their feet. It is formed on the upper peripheral part of this bathtub body,
The lower end portion of the bath tub frame described above is sealed and attached in a watertight manner, and when the bath tub frame is extended upward, the bath tub has a depth suitable for bathing.

In the present invention, the bathtub frame is not particularly limited as long as it is vertically expandable and contractible and ensures watertightness. Specifically, for example, metal such as stainless steel or synthetic resin is used. Further, a bellows shape made of synthetic rubber or the like, a structure in which inner and outer plate materials adjacent to each other are connected by a rubber sheet or a synthetic resin sheet and configured to slide in a watertight state, an outer cylindrical shape There are a thing and a thing made up of an inner cylindrical thing which can be slid in a state where watertightness is secured thereto, and a bag material which stands up when pouring hot water into the inside and inflating it.

The bellows-shaped bath tub frame is used by pulling it up when bathing, and the pulling and pulling down can be done by holding the bath tub frame by hand, and the operation of a wire or string for vertically moving the bath tub frame. It is also possible to have a structure in which the tool is hung from the upper side of the bathtub body or the like, and the operation tool is vertically pulled to manually move the bathtub frame up and down.

In the present invention, instead of this structure, the wire or cord is actuated by driving a motor to move the bathtub frame up or down, or the cylinder is extended or retracted to move the bathtub frame up or down. The structure may be such that the motor drive and the cylinder expansion / contraction operation switch input operation is performed manually,
Alternatively, if the structure is such that it can be operated by a remote controller or automatically by a sensor such as an optical sensor or a far-infrared sensor, usability will be further improved.

In addition, the inner and outer plate members adjacent to each other are connected by a rubber sheet or a synthetic resin sheet and slid in a watertight state. It can be pulled up to and used. Further, the sliding or pulling up or pulling down of the plate material is carried out by holding the bathtub frame by hand, and similarly to the case of the bellows-shaped bathtub frame, a structure for vertically moving the bathtub frame by using an operation tool or the like. It may be configured as.

Further, the bathtub frame, which is composed of an outer tubular body and an inner tubular body which is slidable while maintaining watertightness thereof, moves upward while sliding the inner tubular body when bathing. It can be pulled up to and used. Also, pulling up and down by sliding this inner cylindrical one is carried out by holding the bathtub frame by hand, and like the case of the bellows-shaped bathtub frame,
The bathtub frame may be moved up and down by using the operation tool.

The bathtub frame made of the bag material has a waterproof treatment applied to the bag material, and the shape that swells when hot water is poured into the bathtub frame has a thin width and stands up to a large extent to fill the inside of the bag material. When hot water is poured into the bathtub, the hot water flows out of the upper outlet into the bathtub, and the bag material is kept in a proper tension at all times. Alternatively, it is preferable that the hot water drainage from the bathtub frame is forcibly performed using an intake / drainage pump.

In the bathtub of the present invention, the bathtub body is provided with a heating device capable of heating the bathtub body to keep it warm even in an empty state. Be beneficial.

That is, when the temperature of the bath is low, especially in winter, when the bather does not have hot water, he or she feels uncomfortable because the body is cold, or the bedridden old man, etc. There is a case where the person moves from the bed to the bathtub and moves in the bathtub to take a bath in a place where hot water may be scattered around, but during this movement, the body is often cold and uncomfortable.

In such a case, such problems can be solved by warming the stool or the bathtub body with a heating device such as electricity.

Concretely, there are various methods, for example, stools or bathtub bodies are covered with heating wires or carbon fibers, or an electric heater is provided in the bathtub body.

In the present invention, as will be described later, a watertight bag-like sheet is provided in the bathtub body along the bottom surface and the peripheral side surface portion so as to be vertically expandable and contractible. If configured in this way,
The bathtub frame does not necessarily need to be watertight.

The bathtub of the present invention can be fully utilized even with the structure as it is.
If casters are attached, it is desirable that when a bather has difficulty walking to the extent that he or she uses a wheelchair, the result is that the bather can move to the side of the bed, for example, which further reduces the burden on the caregiver and caregiver.

In the present invention, the bathtub body and the hot and cold water supply device for communicating hot water between the bathtub body are connected to each other via the hot and cold water supply pipe. It is desirable that the hot water can be circulated between them, and that additional cooking can be performed, and the hot water is not wasted.

In this case, instead of using the hot water supply / exhaust device, the hot water can be supplied to the bathtub by using a hot water supply device at home and using a heat resistant hose or the like. As for the shower, for example, the shower in the bathroom can be extended and used.

In the present invention, if the shower nozzle is provided inside the upper part of the peripheral side surface of the bathtub body,
It is useful because it can be used as a shower box as well as a bath.

In this case, if the shower nozzle is attached to the tip of the flexible hot water supply pipe, and the shower nozzle is detachably hung on the upper inside of the peripheral side surface of the bathtub body, the person with a physical disability will be injured. A bather such as a person holds a shower nozzle and applies a shower to any part of the body, and a caregiver or a caregiver holds a shower nozzle and applies a shower to any part of the body of a bather. Therefore, it is extremely easy to handle.

The bathtub of the present invention also includes a bathtub heating device provided for the case where the temperature of the bathwater supplied to the bathtub is low. Examples of this heating device include a fixed heating device fixed around or near the bathtub, and a throwing-type heating device that can be put in and taken out from the bathtub body. Further, in order to enhance the bathing effect, it is also beneficial to have a bath water circulating device and a bath water jet or spring device.

Further, in the present invention, when a watertight bag-like sheet is provided in the bathtub main body along the bottom surface and the peripheral side surface so as to be vertically expandable and contractible, the watertightness of the bathtub is provided by the bag-like sheet. This is extremely beneficial as it will ensure even more.

Further, in the present invention, when a hanging tool and / or a placing section for bathing goods are provided on the inner side of the peripheral side surface of the bathtub body, soap, shampoo or conditioner, towel or sponge is provided at this location. As a result, you can put
These can be easily arranged.

By the way, in the present invention, a holding member for holding the bathtub is provided on the outer peripheral portion of the bathtub so that the bather does not fall down even when leaning against the bathtub, or the shower nozzle is hung on the holding member. Alternatively, the holding member may have a structure that can be used for the handrail of a bather.
