Description

【０００１】
【発明の属する技術分野】
本発明は、入浴者が入浴中に失神状態に陥って溺死する事故を防止する溺死防止用浴槽に関する。
【０００２】
【従来の技術】
政府発表の平成９年の人口動態統計によると、一般家庭内の入浴中における溺死者は、２８９１名に及ぶ。心臓疾患者および高齢者が、温度差による急激な血圧変化に耐えきれず、失神状態に陥って溺死していることによる。しかるに、高齢化社会に対応するために、浴室のバリアフリー化、浴槽のまたぎ込み高さの制限、浴室壁面へのグリップの設置、浴槽内底面の滑り止めの設置などが各種検討されている。しかし、入浴中の溺死防止対策に関しては、関心が払われていないのが実情である。
【０００３】
僅かに関連公知技術として特開平６−２３３８０２号公報、実用新案登録第３０５４８８６号公報、実開昭５９−１３４４８８号公報を認めることができる。これらは、入浴者がリラックスして入浴できるよう、浴槽内に背もたれ具を別途付設するものである。そこにおいては、入浴者が背もたれ具に背もたれ状態で入浴中に、湯船内に足元側へ滑り落ちないようにした配慮がなされており、これが溺死防止用にもなる点は評価できる。
【０００４】
【発明が解決しようとする課題】
しかし、前出の背もたれ具の類を浴槽内に別途持ち込む形態は、これを必要としない他の入浴者には無用の長物と化し、浴槽内を徒らに狭くするだけである。それが高齢者にとって正しく使用できず、却って溺死を促すことにもなりかねない。
【０００５】
そこで本発明の目的は、浴槽本体の内面形状これ自体に改良を加え、入浴の妨げにはならずに溺死を有効に防止し得る浴槽を提供するにある。
【０００６】
【課題を解決するための手段】
本発明に係る浴槽は、図１に示すごとく浴槽本体１の背もたれとなる後側内壁面２が、後ろ上がりの傾斜面に形成されており、浴槽本体１の内底面３が、前上がりの傾斜面に形成されている。具体的には、浴槽本体１の内底面３に、左右幅方向に走る段部５が前後間にわたって所定間隔置きに突出形成されている。更に浴槽本体１の内底面３において、隣接する段部５・５間の段面３ａが水平面に形成されている。
【０００７】
または、本発明に係る浴槽は、図２に示すごとく浴槽本体１の背もたれとなる後側内壁面２が、後ろ上がりの傾斜面に形成されており、浴槽本体１の後ろ側には、後側内壁面２の下端から前方に向けて張り出し形成した半身浴用の上げ底面６が形成されており、上げ底面６の前端と、これよりも低い浴槽本体１の内底面３とが、立側壁７でつながっており、上げ底面６が、前上がりの傾斜面に形成されている。具体的には、浴槽本体１の内底面３が、前上がりの傾斜面に形成されている。更に、浴槽本体１の内底面３には、左右幅方向に走る段部５が前後間にわたって所定間隔置きに突出形成されている。
【０００８】
【発明の作用効果】
本発明によれば、後側内壁面２が後ろ上がりの傾斜面に形成されているので、入浴者が前のめりになることはない。湯船で入浴者が浴槽本体１の後側内壁面２に背もたれ状態で入浴中に失神状態に陥っても、浴槽本体１の内底面３が前上がりの傾斜面に形成されているので、入浴者の臀部が内底面３において前方の足先側にズレ動かない。従って、これら相まって入浴者の顔が湯船につかって溺死することはない。浴槽本体１の内底面３に段部５が形成されているので、入浴者が前方の足先側にズレ動くのを有効に規制できるとともに、隣接する段部５・５間の段面３ａが水平面に形成されていることと相まって、入浴者が浴槽本体１内に跨ぎ入る際などに該段部５が滑り止め機能をも有効に発揮する。
【０００９】
浴槽本体１に、後側内壁面２につながる上げ底面６が形成されている浴槽においては、入浴者が臀部を上げ底面６に載せて半身浴をしている際に失神状態に陥っても、浴槽本体１の後側内壁面２が後ろ上がり傾斜面になっているとともに、上げ底面６が前上がりの傾斜面になっているので、入浴者は背中を後側内壁面２に預けた後傾姿勢にあって前のめりになることはなく、常に入浴者の顔面は浴槽本体１の後側内壁面２の上端にあって顔が湯船につかることはないし、臀部が内底面３に滑り落ちることもない。そのうえで、浴槽本体１の内底面３が前上がり傾斜面に形成されていると、本来の入浴中に入浴者の臀部が該内底面３上にあって背中を上げ底面６の前端に預けた後傾姿勢にあるときも、入浴者が失神状態下で臀部が前方へズレ動いて溺死することをよく防止し得る。
【００１０】
【発明の実施の形態】
（第１実施例）図１は本発明に係る浴槽の第１実施例を示す。符号１は、前後長さ寸法が左右幅寸法より大きく設定された浴槽本体である。浴槽本体１は、後側内壁面２が後ろ上がり傾斜面に形成されており、内底面３が前上がり傾斜面に形成されている。後側内壁面２の鉛直線に対する傾斜角度θ１は、１０〜２０°、具体的には約１５°に設定し、内底面３の水平線に対する傾斜角度θ２は、５〜１０°、具体的には約６°に設定してある。後側内壁面２と内底面３とは実質的に直角となるように設定されている。
【００１１】
浴槽本体１の内底面３には、左右幅方向に走る多数の段部５が前後間にわたって適当間隔置きに突出形成されており、前後に隣接する段部５・５間の段面３ａは水平面に形成されている。浴槽本体１の内底に設けるべき排水口は、内底面３の後端において左右の一端側に配する。
【００１２】
浴槽本体１の後側内壁面２は後傾しているので、入浴者は後側内壁面２に背をもたせ掛けて入浴することになる。その際に、入浴者が失神状態に陥っても、前傾姿勢になることはなく、顔面が湯船につかることはない。しかも、入浴者の臀部は内底面３の後端側にあるところ、内底面３が前上がり傾斜面になっているので、体重が加わった状態において入浴者の臀部が内底面３上を前方に向かって滑り動くことがなく、従ってこの点でも入浴者の頭部がズルズルと湯船につかり込むことがない。
【００１３】
内底面３には段部５が形成されているので、入浴者の臀部や脚部が該段部５に突っ掛かって臀部の前方への滑り移動を有効に阻止する。入浴者が浴槽本体１内に出入りする際に、段部５の介在で足裏が誤って滑ることもよく防止する。隣接する段部５・５間の段面３ａが水平面であると、足先側が滑るのをよく防止できることにもなる。
【００１４】
（第２実施例）図２は本発明に係る浴槽の第２実施例を示す。この場合の浴槽は半身浴用になっており、浴槽本体１の後ろ側には、後側内壁面２の下端から前方に向けて張り出し形成した上げ底面６が形成されており、この上げ底面６の前端と、これより低位にある内底面３とが、立側壁７でつながっている。
【００１５】
かかる半身浴用の浴槽において、浴槽本体１の後側内壁面２が後ろ上がりの傾斜面に形成されているとともに、内底面３が前上がりの傾斜面に形成されている。内底面３には左右幅方向に走る多数の段部５が前後間にわたって適当間隔置きに突出形成されており、前後に隣接する段部５・５間の段面３ａは水平面に形成されている。この場合、後側内壁面２の鉛直線に対する傾斜角θ１は約１０°、内底面３の水平線に対する傾斜角θ２は約１０°に設定した。そして、上げ底面６の水平線に対する傾斜角θ３は約１５°に設定し、前記立側壁７の内面は後ろ上がり傾斜面に形成し、その鉛直線に対する傾斜角θ４は約１０°に設定した。
【００１６】
第２実施例の浴槽においては、入浴者が上げ底面６に腰を掛けると、半身浴になる。その際に、入浴者が失神状態に陥っても、入浴者が後側内壁面２に背もたれ状態にある限り、上げ底面６は前上がりの傾斜面になっているので、臀部が上げ底面６の前方へズレ動き難く、従って臀部が内底面３にズレ落ちて顔面が湯船につかることはない。入浴者が臀部を内底面３の後端側に載せ、背中を立側壁７を介して上げ底面６の前端にもたせ掛けた入浴中に、失神状態に陥っても、内底面３が前上がり傾斜面に形成されているので、臀部が内底面３上にあって前方へズレ動き難く、従って顔面が湯船につかることをよく防止できる。段部５は第１実施例と同様の機能を果たす。なお、第２実施例においても、浴槽本体１の内底に設けるべき排水口は、内底面３の後端において左右の一端側に設けることができる。
【００１７】
図示例の全容は以上のようになっているが、例えば排水口は内底面３の前端側に設け、内底面３上の湯水が内底面３の後端側から左右の一端側の排水路を経てて排水口より排出されるようにしてもよい。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a drowning prevention bathtub that prevents a bather from falling into a fainting state while bathing and drowning.
[0002]
[Prior art]
According to the 1997 demographic statistics released by the government, 2891 people drowned while bathing in ordinary households. Heart disease and the elderly are unable to withstand sudden changes in blood pressure due to temperature differences, fall into syncope and drown. However, in order to cope with the aging society, various studies are being made on making the bathroom barrier-free, limiting the height of the bathtub straddling, installing a grip on the bathroom wall, and installing a non-slip on the bottom of the bathtub. However, no attention has been paid to drowning prevention measures during bathing.
[0003]
Japanese Patent Application Laid-Open No. Hei 6-233802, Japanese Utility Model Registration No. 3054886, and Japanese Utility Model Application Laid-Open No. 59-134488 can be slightly recognized as related arts. These are provided with a backrest separately in the bathtub so that the bather can relax and take a bath. In this regard, consideration has been given to prevent the bather from sliding down into the bathtub to the side of the feet while bathing in the state where the bather is resting on the backrest, and it can be appreciated that this also serves to prevent drowning.
[0004]
[Problems to be solved by the invention]
However, the form in which the above-mentioned backrests are separately brought into the bathtub is unnecessary for other bathers who do not need it, and only the inside of the bathtub is narrowed unnecessarily. It could not be used properly by the elderly and could even lead to drowning.
[0005]
Therefore, an object of the present invention is to provide a bathtub that improves the inner shape itself of the bathtub body itself and can effectively prevent drowning without hindering bathing.
[0006]
[Means for Solving the Problems]
In the bathtub according to the present invention, as shown in FIG. 1, a rear inner wall surface 2 serving as a backrest of the bathtub body 1 is formed with a slope rising rearward, and an inner bottom surface 3 of the bathtub body 1 is tilted upward and forward. Formed on the surface. Specifically, on the inner bottom surface 3 of the bathtub main body 1, step portions 5 running in the left-right width direction are formed so as to protrude at predetermined intervals over the front-rear direction. Further, on the inner bottom surface 3 of the bathtub body 1, a step surface 3a between adjacent step portions 5, 5 is formed in a horizontal plane.
[0007]
Alternatively, in the bathtub according to the present invention, as shown in FIG. 2, a rear inner wall surface 2 serving as a backrest of the bathtub main body 1 is formed on an inclined surface that rises rearward, and a rear side of the bathtub main body 1 has a rear side. A raised bottom surface 6 for a half-body bath is formed so as to protrude forward from the lower end of the inner wall surface 2, and a front end of the raised bottom surface 6 and an inner bottom surface 3 of the bathtub body 1 lower than this are formed by an upright side wall 7. The raised bottom surface 6 is formed on an inclined surface rising forward. Specifically, the inner bottom surface 3 of the bathtub main body 1 is formed as an inclined surface rising forward. Further, on the inner bottom surface 3 of the bathtub main body 1, step portions 5 running in the left-right width direction are formed so as to protrude at predetermined intervals in the front-rear direction.
[0008]
Operation and Effect of the Invention
According to the present invention, since the rear inner wall surface 2 is formed on the inclined surface rising upward, the bather does not turn forward. Even if the bather falls into a fainting state during bathing while resting on the rear inner wall surface 2 of the bathtub body 1, since the inner bottom surface 3 of the bathtub body 1 is formed as a slope rising forward, the bather Buttocks do not move to the front toe side on the inner bottom surface 3. Therefore, the face of the bather does not drown in the bathtub. Since the step portion 5 is formed on the inner bottom surface 3 of the bathtub main body 1, it is possible to effectively restrict the bather from moving to the front toe side, and the step surface 3a between the adjacent step portions 5.5 is formed. In combination with being formed on the horizontal surface, when the bather crosses the bathtub main body 1 and the like, the stepped portion 5 also effectively exerts a non-slip function.
[0009]
In the bathtub in which the raised bottom surface 6 connected to the rear inner wall surface 2 is formed in the bathtub body 1, even if the bather raises his buttocks and rests on the bottom surface 6 and takes a half-body bath, he may fall into a faint state. Since the rear inner wall surface 2 of the bathtub body 1 is inclined backward and the raised bottom surface 6 is inclined forward, the bather leaves his back to the rear inner wall surface 2 and leans. The posture of the bather does not bend forward, the face of the bather is always at the upper end of the rear inner wall surface 2 of the bathtub body 1 and the face does not touch the bathtub, and the buttocks do not slip down to the inner bottom surface 3. . In addition, if the inner bottom surface 3 of the bathtub body 1 is formed as a front-inclined inclined surface, after the bather's buttocks are on the inner bottom surface 3 during the original bathing and the back is raised and deposited on the front end of the bottom surface 6 Even in a tilted posture, the bather can be prevented from drowning due to the buttocks moving forward in a faint state.
[0010]
BEST MODE FOR CARRYING OUT THE INVENTION
First Embodiment FIG. 1 shows a first embodiment of a bathtub according to the present invention. Reference numeral 1 denotes a bathtub body in which the front and rear lengths are set to be larger than the right and left widths. The bathtub body 1 has a rear inner wall surface 2 formed on a rearwardly inclined surface, and an inner bottom surface 3 formed on a frontwardly inclined surface. The inclination angle θ1 of the rear inner wall surface 2 with respect to the vertical line is set at 10 to 20 °, specifically, about 15 °, and the inclination angle θ2 of the inner bottom surface 3 with respect to the horizontal line is 5 to 10 °, specifically, It is set at about 6 °. The rear inner wall surface 2 and the inner bottom surface 3 are set to be substantially perpendicular.
[0011]
On the inner bottom surface 3 of the bathtub body 1, a number of step portions 5 running in the left-right width direction are formed at appropriate intervals over the front and rear, and the step surfaces 3a between the front and rear adjacent step portions 5 are horizontal surfaces. Is formed. Drainage holes to be provided in the inner bottom of the bathtub body 1 are arranged at one end on the left and right at the rear end of the inner bottom surface 3.
[0012]
Since the rear inner wall surface 2 of the bathtub body 1 is inclined backward, the bather leans back on the rear inner wall surface 2 to take a bath. At this time, even if the bather falls into a fainting state, the bather does not lean forward and his face does not touch the bathtub. Moreover, since the buttocks of the bather are on the rear end side of the inner bottom surface 3 and the inner bottom surface 3 is inclined upward, the buttocks of the bather move forward on the inner bottom surface 3 in a state where weight is added. There is no sliding movement, so that even in this respect the bather's head does not slip into the bathtub.
[0013]
Since the step 5 is formed on the inner bottom surface 3, the buttocks and legs of the bather hit the steps 5 and effectively prevent the buttocks from sliding forward. When a bather enters and exits the bathtub body 1, the step soles 5 prevent the sole from slipping accidentally. If the step surface 3a between the adjacent step portions 5 is a horizontal surface, the toe side can be prevented from slipping well.
[0014]
Second Embodiment FIG. 2 shows a bathtub according to a second embodiment of the present invention. In this case, the bathtub is for a half-body bath, and a raised bottom surface 6 is formed on the rear side of the bathtub body 1 so as to protrude forward from the lower end of the rear inner wall surface 2. The front end and the lower inner bottom surface 3 are connected by an upright side wall 7.
[0015]
In such a bathtub for a half-body bath, the rear inner wall surface 2 of the bathtub main body 1 is formed on an inclined surface rising rearward, and the inner bottom surface 3 is formed on an inclined surface rising forward. A large number of steps 5 running in the left-right width direction are formed on the inner bottom surface 3 at appropriate intervals over the front and rear directions, and the step surfaces 3a between the front and rear adjacent steps 5 are formed in a horizontal plane. . In this case, the inclination angle θ1 of the rear inner wall surface 2 with respect to the vertical line was set to about 10 °, and the inclination angle θ2 of the inner bottom surface 3 with respect to the horizontal line was set at about 10 °. The inclination angle θ3 of the raised bottom surface 6 with respect to the horizontal line was set at about 15 °, the inner surface of the upright side wall 7 was formed as a rear-inclined inclined surface, and the inclination angle θ4 with respect to the vertical line was set at about 10 °.
[0016]
In the bathtub of the second embodiment, when a bather sits on the raised bottom surface 6, the bathtub becomes a half-body bath. At that time, even if the bather falls into a faint state, the raised bottom 6 is a slope that rises forward as long as the bather is in a backrest state on the rear inner wall surface 2. It is difficult to shift forward, so that the buttocks do not slip to the inner bottom surface 3 and the face does not touch the bathtub. Even if the bather puts his buttocks on the rear end side of the inner bottom surface 3 and raises his back via the upright side wall 7 and leans on the front end of the bottom surface 6, the inner bottom surface 3 tilts forward even when falling into a faint state. Since it is formed on the surface, the buttocks are on the inner bottom surface 3 and are hard to shift forward, so that it is possible to prevent the face from hitting the bathtub. The step 5 performs the same function as in the first embodiment. In the second embodiment as well, a drain port to be provided at the inner bottom of the bathtub body 1 can be provided at one end on the left and right at the rear end of the inner bottom surface 3.
[0017]
Although the entire volume of the illustrated example is as described above, for example, the drainage port is provided at the front end side of the inner bottom surface 3, and the hot water on the inner bottom surface 3 passes from the rear end side of the inner bottom surface 3 through the drainage channel on one left and right end sides. May be discharged from the drain port.
