Description

本発明は、浴室において使用される椅子に関するものである。   The present invention relates to a chair used in a bathroom.

病人、老人、身体障害者などは、入浴に際して、背もたれのある椅子に腰掛けて、体を洗うのが好都合である。そしてこのような椅子は、人が腰掛ける座部と、人がもたれる背もたれ部と、これらの座部と背もたれ部を支える脚部を備えて形成されているが、嵩張るので、狭い浴室で使用する際には、不使用時に折り畳んでコンパクトにできることが望ましい。   When taking a bath, it is convenient for a sick person, an elderly person, a disabled person, etc. to sit on a chair with a backrest and wash their bodies. Such a chair is formed with a seat on which a person sits, a backrest on which a person rests, and legs that support these seats and the backrest. For this, it is desirable that it can be folded and compact when not in use.

このため、脚部を折り畳むことができるようにする他に、座部を上方へ回動自在にして、脚部を折り畳む際に座部を回動させて折り畳むことができるようにし、椅子をよりコンパクト化できるようにすることが行なわれている(例えば特許文献1等参照)。   For this reason, in addition to enabling the leg to be folded, the seat can be pivoted upward so that the seat can be rotated and folded when the leg is folded. Making it compact is performed (for example, refer patent document 1 etc.).

このように座部を折り畳み回動できるようにした浴室用椅子において、座部を水平に倒して腰掛けることができるようにした状態に保持し、安定して座部の上に座ることができるようにするために、座部をこの水平状態に保持するロック装置を備えたものが提案されている(特許文献2参照)。   In the bathroom chair that can be folded and rotated in this manner, the seat can be held in a state where it can be seated by lying down horizontally, so that it can sit on the seat stably. In order to achieve this, a device provided with a lock device that holds the seat in this horizontal state has been proposed (see Patent Document 2).

特許文献2に係る椅子は、図13に示すように、脚部1を前脚8と後脚9とを回動自在に連結して形成すると共に、前脚8を延長して形成した背もたれ支柱11に背もたれ部3を設け、座部2を脚部1に上下回動自在に取り付けることによって形成してある。そして図13(a)に示すように、座部2の後端縁に凹所20を形成し、この凹所20内にロック装置21が設けてある。ロック装置21は、軸22で枢支されたハンドル23を備えて形成されるものであり、ハンドル23の下部に係合爪24を設けると共にハンドル23の後端部に解除操作具25を設け、バネ26によってハンドル23を下方へ回動付勢するようにしてある。   As shown in FIG. 13, the chair according to Patent Document 2 includes a leg portion 1 formed by connecting a front leg 8 and a rear leg 9 so as to be rotatable, and a backrest column 11 formed by extending the front leg 8. The backrest 3 is provided, and the seat 2 is attached to the leg 1 so as to be pivotable up and down. As shown in FIG. 13A, a recess 20 is formed in the rear end edge of the seat portion 2, and a lock device 21 is provided in the recess 20. The locking device 21 is formed with a handle 23 pivotally supported by a shaft 22, an engaging claw 24 is provided at the lower portion of the handle 23, and a release operation tool 25 is provided at the rear end portion of the handle 23. The handle 23 is urged to rotate downward by a spring 26.

脚部1にはロックバー27が設けてあり、座部2を回動して水平状態にしたときに、図13(a)のようにハンドル23の係合爪24がロックバー27に係合し、座部2がこの水平状態に保たれるようになっている。従って、座部2の前端部に腰かけるなどしても、不用意に座部2が上方へ回動するようなことなく、安定して座部2に座ることができるものである。   The leg portion 1 is provided with a lock bar 27, and when the seat portion 2 is rotated to be in a horizontal state, the engaging claw 24 of the handle 23 is engaged with the lock bar 27 as shown in FIG. The seat 2 is maintained in this horizontal state. Therefore, even when sitting on the front end portion of the seat portion 2, the seat portion 2 can be stably seated without causing the seat portion 2 to rotate carelessly.

そして椅子を折り畳む際には、ハンドル23の後端部の解除操作具25を上方へ引き上げることによって、バネ26に抗してハンドル23を上方へ回動させ、ロックバー27に対する係合爪24の係合を解除することができる。このようにロック装置21による係合を解除することによって、座部2を上方へ回動させることができ、図13(b)のように椅子を折り畳むことができるものである。   When the chair is folded, the release operation tool 25 at the rear end of the handle 23 is pulled upward to rotate the handle 23 upward against the spring 26, so that the engagement claw 24 with respect to the lock bar 27 is engaged. The engagement can be released. By releasing the engagement by the lock device 21 in this way, the seat portion 2 can be rotated upward, and the chair can be folded as shown in FIG.

The release operation tool 5 is rotatable up and down between the state shown in FIG. 2 where the stopper piece 67 contacts the outer surface of the fixture 54 and the state where the lever piece 66 is lifted obliquely upward.

そして上記のロック装置4のロック具57と、解除操作具5の間には、レリースワイヤ6が取り付けてある。レリースワイヤ6は可撓性のチューブ70内にワイヤ71を挿通して形成されるものである。すなわち、このレリースワイヤ6の一端において、チューブ70から突出するワイヤ71が図9(a)のようにロック具57のワイヤ連結部60に連結固定してある。レリースワイヤ6はケーシング58の後端部のレリース導出開口72を通してケーシング58から導出してあり、図5、図6のようにレリースワイヤ6の中途部を座部2の下面に固定し、さらに一方の前脚8のパイプ内にレリースワイヤ6を差し込んである。このレリースワイヤ6を背もたれ支柱11のパイプ内に通し、レリースワイヤ6の他端を導出して、図9(b)のようにチューブ70から突出するワイヤ71が解除操作具5に連結固定してある。 A release wire 6 is attached between the locking device 57 of the locking device 4 and the release operation device 5. The release wire 6 is formed by inserting a wire 71 into a flexible tube 70. That is, at one end of the release wire 6, the wire 71 protruding from the tube 70 is connected and fixed to the wire connecting portion 60 of the lock tool 57 as shown in FIG. The release wire 6 is led out from the casing 58 through the release lead-out opening 72 at the rear end of the casing 58, and the middle part of the release wire 6 is fixed to the lower surface of the seat portion 2 as shown in FIGS. The release wire 6 is inserted into the pipe of the front leg 8. The release wire 6 is passed through the pipe of the backrest column 11, the other end of the release wire 6 is led out, and the wire 71 protruding from the tube 70 is connected and fixed to the release operation tool 5 as shown in FIG. is there.

また、脚部1の前脚8と後脚9の間にはバネ7が図4のように取り付けてある。バネ7は、両端の係止用線部7a,7bとその間のコイル部7cとから成るねじりコイルバネとして形成されるものであり、コイル部7cを前脚8と後脚9とを枢支連結する軸ピンからなる枢支部12の外周に嵌めると共に、一方の係止用線部7aを後脚9の後ヒンジ34に突設した後バネ受け部73に巻き付け係止し、他方の係止用線部7bを前脚の前ヒンジ33に張り出して設けた前バネ受け部74に引掛け係止してある。従って、バネ7の弾性力は、前後のヒンジ33,34を介して前脚8と後脚9に、枢支部12を中心にして前脚8と後脚9を閉じるように近接させる方向に回動させる力として作用するものである。   A spring 7 is attached between the front leg 8 and the rear leg 9 of the leg 1 as shown in FIG. The spring 7 is formed as a torsion coil spring composed of locking wire portions 7a and 7b at both ends and a coil portion 7c therebetween, and the coil portion 7c is a shaft for pivotally connecting the front leg 8 and the rear leg 9 to each other. While being fitted to the outer periphery of the pivotal support portion 12 made of a pin, one locking wire portion 7a is wound around the rear spring receiving portion 73 projecting from the rear hinge 34 of the rear leg 9 and locked, and the other locking wire portion 7b is hooked and locked to a front spring receiving portion 74 provided to protrude from the front hinge 33 of the front leg. Accordingly, the elastic force of the spring 7 is rotated in the direction of bringing the front leg 8 and the rear leg 9 close to the front leg 8 and the rear leg 9 through the hinges 33 and 34 around the pivot 12 in the center. It acts as a force.

さらに、背もたれ部3の両側において、各背もたれ支柱11に肘掛け76が取り付けてある。肘掛け76は基部を軸ピン77で回動自在に枢支してあり、水平状態と、上方へ跳ね上げた状態との間で上下に回動できるようにしてある。この肘掛け76は必ずしも必要なものではない。   Furthermore, armrests 76 are attached to the backrest columns 11 on both sides of the backrest 3. The armrest 76 is pivotally supported at its base portion by a shaft pin 77 so that it can be turned up and down between a horizontal state and a state in which it is flipped upward. This armrest 76 is not always necessary.

上記のように形成される本発明に係る浴室用椅子にあって、脚1を開くと共に座部2を水平に回動させた状態で、座部2の上に腰掛けて使用されるものである。このように座部2を水平状態にすると、座部2の下面に設けた凸条部40が前脚8間に架設した係合杆37の上に載置されるが、凸条部40の下面には座部2の幅方向で凹条79が凹設してあり、この凹条79に係合杆37が嵌って、脚部1に対して座部2が位置決めされるようになっている。そして、座部2をこのように水平状態へと下方へ回動させると、まず図11(a)のようにロック装置4のロック具57が係合杆37の上に乗る。ロック具57の下面にはガイド傾斜面80が形成してあり、座部2がさらに下方へ回動されて係合杆37に対してこのガイド傾斜面80が押圧されると、ロック具57はバネ63に抗して枢支軸59を中心に上方へa矢印のように回動し、次いでバネ63の弾撥力によってロック具57は逆に下方へb矢印のように回動して、図11(b)に示すように係合杆37にロック具57の係合用凹部61が係合される。 In the bathroom chair according to the present invention formed as described above, it is used by sitting on the seat portion 2 in a state where the leg portion 1 is opened and the seat portion 2 is horizontally rotated. is there. In this way, when the seat portion 2 is in a horizontal state, the ridge portion 40 provided on the lower surface of the seat portion 2 is placed on the engagement rod 37 provided between the front legs 8. A recess 79 is provided in the width direction of the seat 2, and an engagement rod 37 is fitted into the recess 79 so that the seat 2 is positioned with respect to the leg 1. . Then, when the seat portion 2 is pivoted downward to the horizontal state in this way, first, the locking tool 57 of the locking device 4 gets on the engagement rod 37 as shown in FIG. A guide inclined surface 80 is formed on the lower surface of the lock device 57. When the seat 2 is further rotated downward and the guide inclined surface 80 is pressed against the engagement rod 37, the lock device 57 is The lock tool 57 is rotated downwardly as indicated by the arrow b by the elastic force of the spring 63, and is rotated downwardly as indicated by the arrow b. As shown in FIG. 11 (b), the engaging recess 61 of the locking device 57 is engaged with the engaging rod 37.

このように、ロック装置4に設けたロック具57の係合用凹部61が脚部1に設けた係合杆37に係合されることによって、脚部1に対して座部2を係合することができるものであり、座部2を水平状態に固定することができるものである。従って、座部2が不用意に上方へ回動して転倒するなどの事故を未然に防ぐことができるものである。   In this way, the engaging recess 61 of the locking device 57 provided on the locking device 4 is engaged with the engaging rod 37 provided on the leg 1, whereby the seat 2 is engaged with the leg 1. The seat portion 2 can be fixed in a horizontal state. Therefore, it is possible to prevent an accident such as the seat 2 being inadvertently rotated upward and falling.

次に、浴室用椅子を折り畳むにあたっては、まず、係合杆37に対するロック装置4のロック具57の係合を解除する。この係合解除は背もたれ部3に設けた解除操作具5を操作することによって行なうことができる。すなわち、図9(b)のα矢印のように解除操作具5のレバー片66をピン68を中心にして上方へ回動させると、解除操作具5に接続したレリースワイヤ6のワイヤ71の一端が引っ張られる。このようにレリースワイヤ6のワイヤ71が引かれると、ワイヤ71の他端でロック具57が図11(c)のe矢印のように引かれ、図11(c)に示すように、ロック具57はc矢印のようにバネ63に抗して上方へ回動されることになり、係合杆37に対する係合凹部61の係合が解除される。   Next, when the bathroom chair is folded, first, the engagement of the lock tool 57 of the lock device 4 with respect to the engagement rod 37 is released. This disengagement can be performed by operating a release operation tool 5 provided on the backrest 3. That is, when the lever piece 66 of the release operation tool 5 is rotated upward about the pin 68 as indicated by the arrow α in FIG. 9B, one end of the wire 71 of the release wire 6 connected to the release operation tool 5. Is pulled. When the wire 71 of the release wire 6 is pulled in this way, the locking device 57 is pulled at the other end of the wire 71 as shown by an arrow e in FIG. 11C, and as shown in FIG. 57 is rotated upward against the spring 63 as indicated by an arrow c, and the engagement of the engagement recess 61 with the engagement rod 37 is released.

このように、係合杆37に対するロック装置4の係合を解除して、脚部1に対する座部2の係合固定を解除するにあたっては、上記のように背もたれ部3に設けた解除操作具5を操作することによって行なうことができるものである。そして解除操作具5はこのように背もたれ部3という椅子の最高所に位置するので、かがみ込んだりするような必要なく、立った楽な姿勢のまま解除操作具5を操作することができるものであり、ロック装置4の係合解除の操作を容易に行なうことができるものである。しかも解除操作具5のレバー片66を引き上げて上方へ回動させることによって操作を行なうことができるので、立った姿勢のまま腕を下げて指にレバー片66を引掛けることによって、解除操作具5を回動させる操作を容易に行なうことができるものである。 Thus, when releasing the engagement of the lock device 4 with respect to the engagement rod 37 and releasing the engagement and fixation of the seat portion 2 with respect to the leg portion 1, the release operation tool provided on the backrest portion 3 as described above. This can be done by operating 5. Since the release operation tool 5 is thus located at the highest position of the chair, that is, the backrest portion 3, it is possible to operate the release operation tool 5 in an easy standing posture without having to bend down. Yes, the operation of releasing the engagement of the lock device 4 can be easily performed. In addition, since the operation can be performed by pulling up the lever piece 66 of the release operation tool 5 and rotating it upward, the release operation tool can be operated by lowering the arm while standing and holding the lever piece 66 on the finger. The operation of rotating 5 can be easily performed.

ここで、解除操作具5の操作を容易に行なうことができるように解除操作具5を背もたれ部3に設けるようにした結果、座部2の下面のロック装置4と解除操作具5の間の距離が大きくなるが、レリースワイヤ6がロック装置4と解除操作具5の間に設けてあるので、レリースワイヤ6という簡便な機構で、ロック装置4を解除操作具5によって遠隔操作することができるものである。   Here, as a result of providing the release operation tool 5 on the backrest portion 3 so that the operation of the release operation tool 5 can be easily performed, the space between the lock device 4 on the lower surface of the seat portion 2 and the release operation tool 5 is reduced. Although the distance increases, since the release wire 6 is provided between the lock device 4 and the release operation tool 5, the lock device 4 can be remotely operated by the release operation tool 5 with a simple mechanism called the release wire 6. Is.

また、背もたれ部3の上端の中央部には後方へ張り出した上面が平坦な張り出し部13が設けてあり、図9(b)に示すように解除操作具5はこの張り出し部13の直下の位置に配置してある。また張り出し部13と解除操作具5を片手で同時に掴めるように、張り出し部13に近い位置に解除操作具5を配置してある。例えば、張り出し部13の上面と解除操作具5のレバー片66の下面の間の距離が6〜9cm程度になるように設定するのが好ましい。従って、例えば片手の親指を張り出し部13の上に宛がった状態で、同じ片手の人差し指や中指などを解除操作具5のレバー片66の下側に引掛け、この片手を握るようにすることによって、解除操作具5を引き上げる操作をすることができるものであり、強い力で、且つ片手だけの操作で、ロック装置4の係合解除を行なうことができるものである。   In addition, the central portion of the upper end of the backrest portion 3 is provided with a protruding portion 13 having a flat upper surface protruding rearward, and the release operation tool 5 is positioned immediately below the protruding portion 13 as shown in FIG. It is arranged in. Further, the release operation tool 5 is arranged at a position close to the overhang part 13 so that the overhang part 13 and the release operation tool 5 can be grasped simultaneously with one hand. For example, it is preferable to set the distance between the upper surface of the overhanging portion 13 and the lower surface of the lever piece 66 of the release operation tool 5 to be about 6 to 9 cm. Therefore, for example, with the thumb of one hand placed on the overhanging portion 13, the index finger or the middle finger of the same one hand is hooked on the lower side of the lever piece 66 of the release operation tool 5 and the one hand is held. Thus, the operation of pulling up the release operation tool 5 can be performed, and the engagement of the lock device 4 can be released with a strong force and an operation with only one hand.

ここで、レバー片66には上記のように上下に開口する貫通孔14が形成してあるので、人差し指や中指などの指先をこの貫通孔14に下側から差し入れることによって、解除操作具5のレバー片66を引き上げる操作がより容易になるものである。また貫通孔14に差し入れる指の長さを調整することによって、手のひらの大きさに関係なく、張り出し部13と解除操作具5を片手で容易に掴むことができるものである。   Here, since the lever piece 66 is formed with the through-hole 14 that opens up and down as described above, by inserting a fingertip such as an index finger or a middle finger into the through-hole 14 from below, the release operation tool 5 is provided. The operation of pulling up the lever piece 66 becomes easier. Further, by adjusting the length of the finger inserted into the through hole 14, the overhanging portion 13 and the release operation tool 5 can be easily grasped with one hand regardless of the size of the palm.

上記のように解除操作具5を操作してロック装置4の係合を解除し、脚1に対する座部2の係合固定状態を解除すると、前脚8と後脚9を閉じる方向に回動付勢するバネ7が上記のように脚部1に設けてあるので、バネ7の力で前脚8と後脚9は枢支部12を中心にして閉じる方向に自動的に回動する。そしてこのように前脚8と後脚9が閉じる方向へ回動すると、つまり前脚8に対して後脚9が接近する方向に回動すると(図4(a)のa矢印)、後脚9に連結具10によって連結されている座部2の後端部が下方へ引かれて下方へ回動し((図4(a)のb矢印)、座部2の前端部が立ち上がるように上方へ回動されることになり、図10に示すように、脚部1を折り畳むことができると共に座部2を立ち上げて折り畳むことができ、浴室用椅子の折り畳みを行なうことができるものである。 To release the engagement of the locking device 4 by operating the release operation member 5 as described above, when disengaged fixed state of the seat 2 with respect to the leg 1, pivot the front legs 8 and the rear leg 9 closing direction Since the spring 7 to be urged is provided on the leg portion 1 as described above, the front leg 8 and the rear leg 9 are automatically rotated in the closing direction around the pivot portion 12 by the force of the spring 7. Then, when the front leg 8 and the rear leg 9 are rotated in the closing direction, that is, when the rear leg 9 is rotated in the direction approaching the front leg 8 (a arrow in FIG. 4A), the rear leg 9 is moved. The rear end of the seat 2 connected by the connector 10 is pulled downward and pivots downward (arrow b in FIG. 4A), and upward so that the front end of the seat 2 rises. As shown in FIG. 10, the leg portion 1 can be folded and the seat portion 2 can be raised and folded, so that the bathroom chair can be folded.

ここで、上記のようにロック装置4の係合を解除する解除操作具5の操作は片手で行なうことができるものであり、そしてロック装置4の係合を解除するとバネ7の作用で脚部1の折り畳み回動と、座部2の折り畳み回動が自動的に行なわれるので、浴室用椅子の折り畳みを片手だけで行なうことが可能になるものである。   Here, the operation of the release operation tool 5 for releasing the engagement of the lock device 4 as described above can be performed with one hand, and when the engagement of the lock device 4 is released, the leg portion is operated by the action of the spring 7. Since the folding of 1 and the folding of the seat 2 are automatically performed, the bathroom chair can be folded with only one hand.

このように浴室用椅子の折り畳みを行なうにあたって、既述のように、前脚8と後脚9を枢着する枢支部12が、前脚8と後脚9の下端を底辺とする二等辺三角形の頂点に位置するように設定されているので、図10に示すように、前脚8と後脚9を折り畳んで狭めた状態でも、自立させることができるものであり、壁にもたれ掛けさせたりする必要なく収納することができるものである。   When folding the bathroom chair in this manner, as described above, the pivotal support portion 12 that pivotally attaches the front leg 8 and the rear leg 9 is an apex of an isosceles triangle with the lower ends of the front leg 8 and the rear leg 9 as the bottom. 10 so that the front leg 8 and the rear leg 9 can be folded and narrowed as shown in FIG. 10 without having to lean against the wall. It can be stored.

次に、このように折り畳んだ浴室用椅子を使用するために開くにあたっては、図12に示すように、後脚9の下端の脚ゴム45を浴室の洗い場など床面82に接地させた状態で、背方へ若干傾けて前脚8の下端を床面82から浮かし、この状態で、背もたれ部3の上端の張り出し部13を下方へ押えることによって行なうことができる。すなわち張り出し部13の上面をa矢印のように下方へ押えると、枢支部12を回動中心として背もたれ支柱11が下方へ回動されると共に、b矢印のように前脚8が上方へ回動され、前脚8は後脚9から離れる方向に回動して、脚1が開く。そして座部2は連結具10を介して後脚9に連結されているので、このように前脚8と後脚9が開くように回動すると、これに連動して座部2がc矢印方向へと水平に倒れるように回動し、脚部1と座部2を開いて、浴室用椅子を使用状態に開くことができるものである。 Next, when opening the bathroom chair for use in this manner, as shown in FIG. 12, the leg rubber 45 at the lower end of the rear leg 9 is in contact with the floor surface 82 such as a bathroom washroom. In this state, the lower end of the front leg 8 is lifted from the floor 82, and the protruding portion 13 at the upper end of the backrest 3 is pressed downward. That is, when the upper surface of the overhanging portion 13 is pressed downward as indicated by an arrow a, the backrest column 11 is rotated downward about the pivotal support portion 12 and the front leg 8 is rotated upward as indicated by an arrow b. , front legs 8 are rotated in a direction away from the rear leg 9, the leg portion 1 is opened.
