【発明が解決しようとする課題】
上記従来の椅子では、吸着解除レバーを手で直接操作するために、必要以上に力を入れて該レバーを引っ張ることが多く、該レバーを何度も操作すると吸盤が破損しやすく、耐久性が劣るという問題点がある。
【０００６】
また、座板の周囲に吸着解除レバーが張り出していると、使用者の行動の邪魔になり、誤って吸着解除レバーに触れた時は、意図しないのに吸盤の吸着を解除して椅子が被吸着面から離れるために安全性に問題点があった。特に、身体障害者、妊婦、病人等が使用する場合には安全性が要求されるが、この安全性を図れないという問題点がある。
【０００７】
本発明は、上記問題点を解決する為に創案されたもので、吸盤の真空解除を行って床から離す技術を課題とし、吸盤が破損し難く耐久性があり、使用時には安全性の高い浴室用椅子の提供を目的としている。
【０００８】

【００１１】
請求項４の浴室用椅子は、請求項１記載の浴室用椅子において、
紐状体１６は、保持部９内の区画壁８近くにある軸体１３に取り付け、該区画壁８の内壁と取手体１２間にある軸体１３にスプリング１４を配置すると共に該軸体１３の先端にはストッパ１５を配置し、取手１１を往復動自在に配設したことを特徴としている。
【００１２】
【発明の実施の形態】
本発明の第１実施例を図１〜図３により、同じく第二実施例を図４により説明すると、本発明は、座板２の下面四隅に脚部１７を垂下設し、該脚部１７の下端に吸盤１８を取り付けた椅子に関するものである。
【００１３】
前記座板２は、ＡＡＳ樹脂等の合成樹脂で成形され、該座板２の対向する両側面内方には、取手１１を水平に往復動自在に組み付けた取手格納部４が設けられている。
【００１４】
この取手格納部４は、座板２の対向する両側面内方にコ字状に形成され、軸孔６及びその近傍、例えば、図２、図３のように軸孔６の両側に２個の紐挿通孔５を設けた区画壁８を、座板２の側壁３より内方に設けた取手収納部７と、該区画壁８を介してその内方に、軸孔６の中心と同一直線上に中心を持つ孔１０を設け、コ字状に形成された保持部９とで構成されている。
【００１５】
また、前記取手格納部４には、軸孔６及び孔１０に挿通させる軸体１３を取手体１２に直角に設けた取手１１がスプリング１４を介して往復動自在に組み付けられ、取手１１と吸盤１８の端部間には、取手１１近傍に位置する紐挿通孔５を経由させて紐状体１６が張設されている。
【００１６】
取手１１を手前に引く事により、吸盤１８の真空解除を行なう場合の第１実施例を、図２、図３により説明する。
取手１１は、使用者が手で引張る部分の取手体１２と取手体１２から直角方向に延びた軸体１３で構成されており、この軸体１３は、軸孔６に挿入できる様な外径に形成すると共に、更に軸孔６より小さい孔１０へ挿通可能に先端部から吸盤１８の真空解除に必要な所定ストローク長で縮径した段部１３ａが形成されている。
取手収納部７の形状に沿って、取手１１の軸体１３を区画壁８の軸孔６と保持部９の孔１０に挿通させると、段部１３ａが、保持部９の孔１０に当たって止まり、軸体１３が保持部９外面から所定ストローク突出した状態に保持される。
この所定ストローク突出部分の軸体１３に、所定ストロークに合わせた全長のスプリング１４を被せてから軸体１３の先端にストッパ１５を嵌めて取手１１を取手格納部４に組み付けている。
従って、使用者が取手体１２を手で掴み取手１１を手前に引けば、軸体１３は軸孔６と孔１０にガイドされ水平方向へ手前側に動き、それに伴ってスプリング１４は、軸体１３の先端と保持部９の外面との間で圧縮され、スプリング１４の圧縮状態で使用者が取手体１２から手を離せばスプリング１４の復元力によって取手１１は元の位置に戻る。
また、軸体１３の断面形状を矩形状にしたから、取手１１が水平に動く時に、軸体１３周りに回転する動きが防止されて、取手１１が取手格納部４に往復動自在に組み付けられている。
紐状体１６の一端は、２個の隣接する一方の吸盤１８の端部１８ａに接続され、紐状体１６の他端は、その吸盤１８の端部１８ａから最短距離にある取手１１との間にあって、取手１１近傍に位置する区画壁８の紐挿通孔５へ内壁から外壁（図３上で左側から右側）に向かって通して紐挿通孔５を経由させた後、軸体１３の取手体１２近くの位置に設けた取付孔１３ｂに挿通する事によって取手１１に接続後、もう一方の紐挿通孔５に外壁から内壁（図３上で右側から左側）に向かって挿通してから他方の吸盤１８の端部１８ａに接続されている。
実施例では、２個の隣接する吸盤１８の端部１８ａ間を一本の紐状体１６で繋いでいるが、紐状体１６を１個の吸盤１８の端部１８ａ毎から取手１１に張設する事でも良い（図示は省略）。
【００１７】
従って、取手格納部４に設けた水平に往復動する取手１１を手前側に引き出す動作により、軸体１３の取付孔１３ｂに挿通している紐状体１６は、紐挿通孔５への経由によって、この位置が起点となり取手１１の水平ストロークが紐状体１６に伝わり、該紐状体１６が吸盤１８の端部１８ａを引張り、該吸盤１８の真空を破り、椅子１を固定した床等から離すことができる。
【００１８】
次に、取手１１を奥に押圧することにより、吸盤１８の真空解除を行う第二実施例の場合を、図４により説明する。
取手１１は、使用者が押圧する取手体１２と該取手体１２から直角方向に延びて断面形状を矩形状とした軸体１３で構成されており、この軸体１３は、軸孔６及び孔１０に挿通できる様な外径にされ、区画壁８の内壁と取手体１２間の軸体１３上にスプリング１４をその間隔に入る全長に配置して、軸体１３は、保持部９外面に先端が出る全長であって、ストッパ１５を先端に嵌めて取手１１を取手格納部４に組み付けている。
従って、使用者が取手１１を奥に押圧すれば、軸体１３は軸孔６と孔１０にガイドされ水平方向へ奥に動き、それに伴ってスプリング１４は、区画壁８の内壁と取手体１２間の間で圧縮され、スプリング１４の圧縮状態で使用者が取手体１２から手を離せばスプリング１４の復元力によって取手１１は元の位置に戻る。
更に、紐状体１６は、保持部９内の区画壁８近くにある軸体１３の取付孔１３ｂに挿通してあるので、取手１１を区画壁８側に押圧する動作により、紐状体１６の紐挿通孔５への経由によって、取手１１の水平ストロークが紐状体１６に伝わり、紐状体１６が吸盤１８の端部１８ａを引張り、該吸盤１８の真空が破れ椅子１を固定した床等から離すことができるのである。
もちろんこの場合も、紐状体１６は、１個の吸盤１８の端部１８ａ毎から取手１１に張設する事でも良い（図示は省略）。
【００１９】
ここで、本発明に至った経緯を述べると、図５は、取手１１を手前に引く事により、吸盤１８の真空解除を行う場合の第一実施例と同様な構成の椅子に、取手１１と吸盤１８間を単に紐状体１６で張設した場合を示したもので、この場合は取手１１の水平ストロークは紐状体１６に伝わらないため取手１１を作動させても吸盤１８を引張ることができず、該吸盤１８は真空解除ができない。
【００２０】
また、図６は、取手体を奥への押圧動作により、吸盤１８の真空解除を行う場合の第二実施例と同様な構成の椅子に、取手１１と吸盤１８間を単に紐状体１６で張設した場合を示したもので、この場合も同様に、取手１１の水平ストロークは紐状体１６に伝わらないため取手１１を作動させても吸盤１８を引張ることができず、該吸盤１８は真空解除ができない。
【００２１】
発明者は、結局、図５、図６のように、ただ単に吸盤１８と取手１１とを紐状体１６で連結しただけでは、吸盤１８の真空解除ができないことに注目して本発明を案出したものである。
【００２２】
【発明の効果】
請求項１の発明により、椅子はしっかりと浴室の床や浴槽の底に載置固定でき、椅子を動かす場合は取手を作動させることにより吸盤の真空解除を行い、浴室の床や浴槽の底から吸盤を簡単に離して椅子を移動させることができる。
また、吸盤の真空解除を行う場合は、取手を手前側に引くか、取手を奥に押圧する動作によって行なわれるため、所定ストローク以上吸盤を引っ張ることがないので、吸盤が破損され難く、椅子は長期間使用でき経済性に優れている。
【００２３】
また、取手は、作動時以外は台板の側面より外に張り出さないため、不用意に取手に接触して吸盤の真空解除を行うことはない。特に体の不自由な状態にある、年配者、身体障害者、妊婦、病人等も安全に使用できるものである。
さらに、取手の引出し又は押圧操作で簡単に吸盤の真空解除が出来るため、病人や年配者、妊婦等でも軽い力で吸盤の真空解除操作が出来る。
【００２４】
請求項２の発明によれば、取手は取手格納部を往復動自在にでき、もって吸盤の真空解除も簡単な動作でできる。
【００２５】
請求項３の発明によれば、取手を手前側に引き出す動作により、吸盤の端部に連結された紐状体が引っ張られて吸盤の吸着を解除し椅子を床より離すことができる。また、取手は操作後、自動的に取手収納部に復帰して格納されるので、張り出し部分がなく、引き出す操作であるため、意図しない解除は極めて起こり難く安全性が高い椅子である。
【００２６】
請求項４の発明によれば、取手を奥に押圧する動作により、吸盤の端部に連結された紐状体を引っ張って吸盤の真空解除を行い椅子を床より離すことができる。また、取手体は座板の側面より一切張り出さないため、安全性の高いものである。

[0012]
BEST MODE FOR CARRYING OUT THE INVENTION
The first embodiment of the present invention will be described with reference to FIGS. 1 to 3 and the second embodiment will be described with reference to FIG. 4. In the present invention, legs 17 are suspended from four corners of the lower surface of the seat plate 2 and And a chair having a suction cup 18 attached to a lower end of the chair.
[0013]
The seat plate 2 is formed of a synthetic resin such as an AAS resin, and a handle storage portion 4 in which a handle 11 is horizontally reciprocally movable is provided inside both opposed side surfaces of the seat plate 2. .
[0014]
The handle storage portion 4 is formed in a U-shape on the inner sides of the opposite sides of the seat plate 2, and two shaft storage holes are provided in the vicinity of the shaft hole 6, for example, as shown in FIGS. The partition wall 8 provided with the string insertion hole 5 is provided with a handle storage portion 7 provided inwardly of the side wall 3 of the seat plate 2, and through the partition wall 8, the partition wall 8 and the center of the shaft hole 6. A hole 10 having a center on a straight line is provided, and the holding portion 9 is formed in a U-shape.
[0015]
A handle 11 having a shaft 13 to be inserted into the shaft hole 6 and the hole 10 at a right angle to the handle 12 is attached to the handle storage portion 4 via a spring 14 so as to be reciprocally movable via a spring 14. A string-like body 16 is stretched between the ends of 18 via the string insertion hole 5 located near the handle 11.
[0016]
A first embodiment in which the vacuum of the suction cup 18 is released by pulling the handle 11 toward the user will be described with reference to FIGS.
The handle 11 is composed of a handle 12 that is pulled by a user and a shaft 13 that extends in a direction perpendicular to the handle 12. The shaft 13 has an outer diameter that can be inserted into the shaft hole 6. In addition, a stepped portion 13a whose diameter is reduced by a predetermined stroke length required for releasing the vacuum of the suction cup 18 from the distal end portion is formed so as to be able to be inserted into the hole 10 smaller than the shaft hole 6.
When the shaft 13 of the handle 11 is inserted through the shaft hole 6 of the partition wall 8 and the hole 10 of the holding portion 9 along the shape of the handle storage portion 7, the step portion 13a hits the hole 10 of the holding portion 9 and stops. The shaft body 13 is held in a state of projecting a predetermined stroke from the outer surface of the holding section 9.
The handle 13 is assembled to the handle storage part 4 by covering a spring 14 of the entire length corresponding to the predetermined stroke on the shaft 13 protruding from the predetermined stroke, and then fitting a stopper 15 to the tip of the shaft 13.
Therefore, when the user grasps the handle body 12 by hand and pulls the handle 11 toward the user, the shaft body 13 is guided by the shaft holes 6 and 10 and moves in the horizontal direction toward the front side. When the user releases the handle 12 in the compressed state of the spring 14, the handle 11 returns to its original position by the restoring force of the spring 14.
In addition, since the cross-sectional shape of the shaft 13 is rectangular, when the handle 11 moves horizontally, the rotation around the shaft 13 is prevented, and the handle 11 is reciprocally assembled to the handle storage unit 4. ing.
One end of the string-like body 16 is connected to ends 18 a of two adjacent suction cups 18, and the other end of the string-like body 16 is connected to the handle 11 which is the shortest distance from the end 18 a of the suction cup 18. After passing through the string insertion hole 5 of the partition wall 8 located in the vicinity of the handle 11 from the inner wall to the outer wall (from left to right in FIG. 3) and passing through the string insertion hole 5, the handle of the shaft 13 After being connected to the handle 11 by being inserted through a mounting hole 13b provided near the body 12, the other string insertion hole 5 is inserted from the outer wall toward the inner wall (from right to left in FIG. 3) and then to the other. Is connected to the end 18a of the suction cup 18.
In the embodiment, the ends 18a of the two adjacent suction cups 18 are connected by one string-shaped body 16, but the string-shaped bodies 16 are stretched to the handle 11 from each end 18a of one suction cup 18. May be provided (not shown).
[0017]
Accordingly, the string-like body 16 inserted through the attachment hole 13b of the shaft 13 is pulled out by the operation of pulling the horizontally reciprocating handle 11 provided in the handle storage unit 4 toward the near side, through the string insertion hole 5. This position serves as a starting point, and the horizontal stroke of the handle 11 is transmitted to the string-like body 16, which pulls the end 18 a of the suction cup 18, breaks the vacuum of the suction cup 18, and moves from the floor or the like on which the chair 1 is fixed. Can be separated.
[0018]
Next, a second embodiment in which the vacuum of the suction cup 18 is released by pressing the handle 11 to the back will be described with reference to FIG.
The handle 11 includes a handle body 12 pressed by a user and a shaft body 13 extending in a direction perpendicular to the handle body 12 and having a rectangular cross section. The shaft body 13 includes a shaft hole 6 and a hole. The spring 14 is arranged on the shaft 13 between the inner wall of the partition wall 8 and the handle 12 over the entire length of the space between the inner wall of the partition wall 8 and the handle 12. The handle 11 is attached to the handle storage unit 4 by fitting the stopper 15 to the tip and having the entire length at which the tip projects.
Therefore, when the user presses the handle 11 to the back, the shaft 13 moves to the back in the horizontal direction guided by the shaft holes 6 and 10, and accordingly, the spring 14 moves the inner wall of the partition wall 8 to the handle 12. When the user releases the handle 12 while the spring 14 is compressed, the handle 11 returns to its original position due to the restoring force of the spring 14.
Further, since the cord 16 is inserted through the mounting hole 13b of the shaft 13 near the partition wall 8 in the holding portion 9, the operation of pressing the handle 11 toward the partition wall 8 causes the cord 16 to move. The horizontal stroke of the handle 11 is transmitted to the string-like body 16 by passing through the string insertion hole 5, the string-like body 16 pulls the end 18a of the suction cup 18, the vacuum of the suction cup 18 is broken, and the floor on which the chair 1 is fixed. And so on.
Of course, also in this case, the string-like body 16 may be stretched to the handle 11 from each end 18a of one suction cup 18 (not shown).
[0019]
Here, the history of the present invention will be described. FIG. 5 shows that a chair having the same structure as that of the first embodiment in which the vacuum of the suction cup 18 is released by pulling the handle 11 toward the front is provided with the handle 11. This shows a case where the space between the suction cups 18 is simply stretched with the string-like body 16. In this case, the horizontal stroke of the handle 11 is not transmitted to the string-like body 16, so that even when the handle 11 is operated, the suction cup 18 can be pulled. The suction cup 18 cannot be released from vacuum.
[0020]
FIG. 6 shows a chair having the same structure as that of the second embodiment in which the vacuum of the suction cup 18 is released by pressing the handle to the back, and the space between the handle 11 and the suction cup 18 is simply formed by the string-like body 16. In this case as well, the horizontal stroke of the handle 11 is not transmitted to the string-like body 16, so that even when the handle 11 is operated, the suction cup 18 cannot be pulled, and the suction cup 18 Cannot release vacuum.
[0021]
The inventor of the present invention devised the present invention by noting that the vacuum of the suction cup 18 cannot be released simply by connecting the suction cup 18 and the handle 11 with the string-like body 16 as shown in FIGS. 5 and 6. It was issued.
[0022]
【The invention's effect】
According to the invention of claim 1, the chair can be firmly placed and fixed on the floor of the bathroom or the bottom of the bathtub. When moving the chair, the vacuum of the suction cup is released by operating the handle, and the suction cup is removed from the floor of the bathroom or the bottom of the bathtub. The chair can be easily moved away.
Further, when releasing the vacuum of the suction cup, since the suction is performed by pulling the handle toward the front side or pressing the handle to the back, the suction cup is not pulled over a predetermined stroke, so the suction cup is hardly damaged, and the chair is It can be used for a long time and is economical.

In addition, the handle does not protrude beyond the side surface of the base plate except during operation, so that the vacuum of the suction cup is not released by accidentally contacting the handle. Particularly, the elderly, the physically handicapped, pregnant women, the sick, etc. who are in a state of physical disability can be used safely.
Furthermore, since the vacuum of the suction cup can be easily released by pulling out or pressing the handle, even a sick person, an elderly person, a pregnant woman, etc. can perform the vacuum release operation of the suction cup with a small force.
[0024]
According to the second aspect of the present invention, the handle can reciprocate the handle storing portion, and thus the vacuum release of the suction cup can be performed by a simple operation.
[0025]
According to the third aspect of the present invention, the string-like body connected to the end of the suction cup is pulled by the operation of pulling the handle toward the front side, the suction of the suction cup is released, and the chair can be separated from the floor. In addition, since the handle is automatically returned to the handle storage portion after operation and stored, there is no protruding portion, and since the operation is a pull-out operation, unintended release is extremely unlikely to occur and the chair is highly safe.
[0026]
According to the invention of claim 4, the chair can be released from the floor by releasing the vacuum of the suction cup by pulling the string-like body connected to the end of the suction cup by the operation of pressing the handle to the back. Further, since the handle body does not protrude from the side surface of the seat plate at all, the safety is high.
