Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bathtub having a function of deforming when a bather's body comes into contact with a side surface or a bottom surface, and relieving the bather's pain due to the contact.

[0002]

2. Description of the Related Art At present, bathtubs generally used include:
Most of them are made of hard materials such as FRP (fiber reinforced resin), enamel and stainless steel.

[0003] In these bathtubs, when the bather takes a bathing posture, the part where the body and the bathtub come into contact does not deform,
Large pressures are locally applied to parts of the body that abut the bathtub, which may cause pain and discomfort. In particular, when using a bath formed of such a hard material for bathing a person with a disease, kyphoscoliosis and those with symptoms of scoliosis protrude from the back during bathing. Bathing can be quite painful, as the spine and the area around it come into close contact with the side of the bathtub in near point contact.

On the other hand, a vinyl tub that is easily deformed is used for a bathtub used for a special purpose, such as a welfare care bathtub. However, such a vinyl bathtub lacks stability when the bather changes his or her posture in the bathtub, and the edge is easily deformed, so that the caregiver can lean on the caregiver. There is a drawback that caregiving becomes difficult due to lack of strength.

[0005]

As described above, a bathtub generally used at present, which is formed entirely of a hard material, is used when a bather's body comes into contact with the side or bottom surface of the bathtub. Due to local high pressure, pain and discomfort may occur. In addition, vinyl bathtubs used for nursing care bathtubs, etc., lack stability when bathers change their postures, and the edge of the bathtub is easily deformed, so that caregivers can care for them. Since it does not have such strength that it can lean on it, there is a disadvantage that care becomes difficult.

In view of the above problems, the present invention has a function of deforming when a bather's body comes into contact with a side surface or a bottom surface, and relieving the bather's pain due to the contact. It is an object of the present invention to provide a bathtub which has high stability and is hardly deformed at the time of changing.

[0007]

In order to achieve the above object, the bathtub of the present invention is provided with a soft portion formed of a soft material at a part of a bathtub body formed of a hard material, The soft part is provided in a part where the bather's body and the bathtub come into contact when the bather takes a bathing posture,
The bather is characterized in that it deforms when a part of the body of the bather comes into contact with the bather, thereby reducing the pain of the bather due to the contact.

[0008] According to the above configuration, the stability is high when the bather enters and leaves, the edge is hardly deformed, and the bather's body is deformed when it comes into contact with the side surface or the bottom surface, and the bather's body is contacted. A bathtub having the function of relieving pain is realized.

Further, it is possible that the soft portion is formed in an opening provided in the bathtub body portion, and the soft portion is formed by a soft sheet.

[0010] Further, by providing the soft portion on the side surface or the bottom surface of the bathtub body portion, it is possible to alleviate the pain generated near the spine and buttocks of a bather.

Further, by using a hard FRP as a kind of hard resin for the hard material and using a soft FRP as a kind of soft resin for the soft material, the bathtub can be easily formed.

Other objects, functions and effects of the present invention will become more apparent from the following description of embodiments with reference to the drawings.
