In this embodiment, when the operating portion OP1 is not operated and the connecting member 9 is positioned at the valve closing position by the biasing member S1, the expandable portion 71a is in the contracted state and the opening at the upper end of the tubular member 72 is closed. It is closed by the upper surface (valve V) of the tubular member 71, which prevents the discharge of the fluid. Further, when the connecting member 9 is operated by the operating portion OP1 to move to the valve open position, the expandable portion 71a is in an extended state, the upper surface (valve V) of the tubular member 71 is separated from the upper end of the tubular member 72, and the driving portion The fluid 31 passes through the gap between the upper end of the tubular member 72 and the upper surface of the tubular member 71 and is discharged to the first outlet passage 61 through the outlet O1 provided in the tubular member 71 .
筒状部材７１の伸縮部７１ａは、本実施形態では蛇腹状に設けられ、連結部材９が移動した際に伸縮しやすく、流体が流れる隙間の確保を容易にしている。また、筒状部材７１の上端には、連結部材９の下端に設けられたフランジ部９１が取り付けられ、付勢部材Ｓ１の下方への付勢力によって、フランジ部９１および筒状部材７１の上面が、管状部材７２の上端の開口を密に閉鎖するように構成されている。

As shown in FIG. 6, when the lifting member 4 reaches a predetermined height position, the actuating portion 42c operates the actuated portion OP2 to open the discharge valve 7, thereby opening the second discharge passage 62. , the fluid is discharged by moving the fluid to the first discharge path 61 . Therefore, when excessive fluid is supplied to the driving portion 31, the fluid is discharged from the discharge valve 7, and plastic deformation or damage of the driving portion 31 due to an excessive amount of fluid is suppressed. The predetermined height at which the actuated portion OP2 is actuated by the actuating portion 42c is not particularly limited. The actuated part OP2 can be set to operate when the elevation body 41 reaches the upper limit of the preset movement range. This predetermined height position is appropriately set according to the material and size of the driving portion 31, the moving range of the lifting member 4, and the like.

As the elevating member 4 rises, the actuating portion 42c comes into contact with the actuated portion OP2 and actuates the actuated portion OP2. The actuated portion OP2 is configured to open the discharge valve 7 by being actuated by the actuating portion 42c. The actuated portion OP2 is located on the moving path of the lifting member 4, and is provided at a position where the operating portion 42c of the lifting member 4 contacts when the lifting member 4 reaches a predetermined height position. In this embodiment, the operated portion OP2 is arranged such that the operating portion 42c contacts the operated portion OP2 when the operating portion 42c reaches the vicinity of the upper end of the guide member G. As shown in FIG.
本実施形態では、被作動部ＯＰ２は、図３～図９に示されるように、作動部４２ｃにより作動される。被作動部ＯＰ２は、本実施形態では連結部材９に接続され、被作動部ＯＰ２が作動部４２ｃにより作動した際に、連結部材９を開弁位置に移動させることにより、排出弁７を開放する。なお、本実施形態では、被作動部ＯＰ２は操作部ＯＰ１と一体に設けられているが、排出弁７を開放させることができれば、操作部ＯＰ１と別体として設けてもよい。
In this embodiment, the actuated portion OP2 is actuated by an actuating portion 42c, as shown in FIGS. 3-9. The actuated portion OP2 is connected to the connecting member 9 in this embodiment, and when the actuated portion OP2 is actuated by the operating portion 42c, the connecting member 9 is moved to the valve opening position, thereby opening the discharge valve 7. . In this embodiment, the actuated portion OP2 is provided integrally with the operation portion OP1, but may be provided separately from the operation portion OP1 as long as the discharge valve 7 can be opened.
被作動部ＯＰ２は、本実施形態では、昇降部材４の昇降方向に沿って移動するように構成されている。本実施形態では、被作動部ＯＰ２が作動部４２ｃにより押圧され、上側に移動することにより、連結部材９も上側に移動して、排出弁７を開放している。なお、被作動部ＯＰ２は、所定の軸周りに回転動作することにより、連結部材９を開弁位置に移動させて排出弁７を開放してもよい。
The operated portion OP2 is configured to move along the elevation direction of the elevation member 4 in this embodiment. In the present embodiment, when the operated portion OP2 is pressed by the operating portion 42c and moves upward, the connecting member 9 also moves upward and the discharge valve 7 is opened. The actuated part OP2 may move the connecting member 9 to the valve opening position to open the discharge valve 7 by rotating around a predetermined axis.
作動部４２ｃは、被作動部ＯＰ２に当接して、被作動部ＯＰ２が作動する方向に押圧等の操作力を加えるように構成されている。作動部４２ｃは、本実施形態では、昇降部材４の移動体４２に設けられているが、被作動部ＯＰ２を作動させることができれば、昇降部材４の移動体４２以外の位置（たとえば昇降本体４１）に設けられていてもよい。移動体４２に作動部４２ｃが設けられている場合は、移動体４２が案内部材Ｇに沿って移動するため、移動体４２の被作動部ＯＰ２に対する位置ずれが生じにくく、作動部４２ｃが被作動部ＯＰ２に当接しやすくなる。
The operating portion 42c is configured to abut against the operated portion OP2 and apply an operating force such as a pressing force in the direction in which the operated portion OP2 is operated. In the present embodiment, the actuating portion 42c is provided on the moving body 42 of the lifting member 4. However, if the operated portion OP2 can be operated, the operating portion 42c can be positioned at a position other than the moving body 42 of the lifting member 4 (for example, the lifting body 41). ) may be provided. When the moving body 42 is provided with the operating portion 42c, the moving body 42 moves along the guide member G. Therefore, the moving body 42 is less likely to be displaced from the operated portion OP2. It becomes easier to abut on the portion OP2.
また、作動部４２ｃは、被作動部ＯＰ２を作動させることができれば、その形状や構造は特に限定されない。本実施形態では、作動部４２ｃは、図５および図６に示されるように、移動体４２の軸心からの突出量が移動体４２の上端側に向かって小さくなる傾斜面を有している。
Further, the shape and structure of the actuating portion 42c are not particularly limited as long as the actuating portion 42c can actuate the actuated portion OP2. In this embodiment, as shown in FIGS. 5 and 6, the actuating portion 42c has an inclined surface in which the amount of protrusion from the axis of the moving body 42 decreases toward the upper end of the moving body 42. As shown in FIGS. .
昇降装置１は、本実施形態では、図３～図９に示されるように、昇降部材４を支持することにより昇降部材４の移動を規制する規制機構８を備えている。規制機構８は、昇降部材４の降下を規制する規制位置（図５、図８等参照）と昇降部材４が下側から上側へと移動するのを許容する退避位置（図７参照）との間を移動する規制部材８１を有している。本実施形態では、規制機構８は、上述した操作ユニットＵに設けられている。
In this embodiment, the lifting device 1 includes a regulating mechanism 8 that regulates movement of the lifting member 4 by supporting the lifting member 4, as shown in FIGS. The regulating mechanism 8 has a regulating position (see FIGS. 5, 8, etc.) for regulating the descent of the elevating member 4 and a retracted position (see FIG. 7) for allowing the elevating member 4 to move from the lower side to the upper side. It has a restricting member 81 that moves between them. In this embodiment, the regulation mechanism 8 is provided in the operation unit U described above.
規制部材８１は、規制位置に位置するときに、昇降部材４が所定の位置よりも下側に降下することを規制する。規制位置に位置する規制部材８１は、昇降部材４が降下しようとする際に、図８に示されるように、昇降部材４と上下方向で係合して、昇降部材４が降下することを規制する。本実施形態では、昇降部材４は、上側から降下したときに規制位置に位置する規制部材８１と係合する被係合部４２ａを有し、規制部材８１が被係合部４２ａと上下方向で係合することにより、昇降部材４が降下することが規制される。
The restricting member 81 restricts the elevating member 4 from descending below a predetermined position when positioned at the restricting position. The regulating member 81 positioned at the regulating position engages with the elevating member 4 in the vertical direction as shown in FIG. do. In this embodiment, the elevating member 4 has an engaged portion 42a that engages with the regulating member 81 positioned at the regulating position when lowered from above, and the regulating member 81 is vertically aligned with the engaged portion 42a. The engagement restricts the descent of the lifting member 4 .
規制部材８１の規制位置は、図５および図８に示されるように、規制部材８１が昇降部材４の昇降移動経路上に位置し、昇降部材４の降下を妨げる位置である。また、規制部材８１の退避位置は、図７に示されるように、規制部材８１が昇降部材４の移動経路から外れ、昇降部材４の上昇および降下を妨げない位置である。後述するように、昇降部材４の押圧または連結部材９の移動によって規制部材８１が退避位置へ移動したときに規制部材８１による移動の規制が解除される。なお、規制位置にある規制部材８１は、たとえば、図５に示されるように、昇降部材４が上昇した位置にあるときに、昇降部材４の被係合部４２ａに対して、下方かつ上下方向で近傍に位置するように設けられる。
The regulating position of the regulating member 81 is, as shown in FIGS. 5 and 8, a position where the regulating member 81 is positioned on the elevation movement path of the elevation member 4 and prevents the elevation member 4 from descending. The retracted position of the regulating member 81 is, as shown in FIG. 7, a position where the regulating member 81 is out of the moving path of the lifting member 4 and does not interfere with the lifting and lowering of the lifting member 4 . As will be described later, when the regulating member 81 is moved to the retracted position by pressing the lifting member 4 or moving the connecting member 9, the regulation of movement by the regulating member 81 is released. Note that the regulating member 81 at the regulating position is, for example, as shown in FIG. are provided so as to be located in the vicinity of each other.
上述したように、本実施形態では、昇降装置１は、規制位置と退避位置との間を移動する規制部材８１を有する規制機構８を備え、昇降部材４が上側から降下したときに、昇降部材４が規制位置に位置する規制部材８１と係合する被係合部４２ａを有している。したがって、たとえば、供給路５、排出路６、駆動部３１、排出弁７などが破損したり、供給路５や排出路６の接続部分が外れたりして駆動部３１に供給された流体が漏れてしまった場合に、昇降部材４が上昇した位置から降下されることが抑制される。したがって、昇降部材４に人や物を載せる作業中に昇降部材４が降下することが抑制され、昇降装置１の使用時の安全性を高めることができる。
As described above, in this embodiment, the lifting device 1 includes the regulating mechanism 8 having the regulating member 81 that moves between the regulating position and the retracted position. 4 has an engaged portion 42a that engages with the regulating member 81 positioned at the regulating position. Therefore, for example, the supply path 5, the discharge path 6, the drive part 31, the discharge valve 7, etc. are damaged, or the connection part of the supply path 5 or the discharge path 6 is disconnected, causing the fluid supplied to the drive part 31 to leak. When the lifting member 4 is lifted, the lifting member 4 is prevented from being lowered from the raised position. Therefore, it is possible to prevent the lifting member 4 from descending during the work of placing a person or an object on the lifting member 4, and the safety of using the lifting device 1 can be enhanced.
規制部材８１は、本実施形態では、図３～図９に示されるように、支持体Ｃに移動可能に設けられている。支持体Ｃは、本実施形態では、図１および図２に示されるように、案内部材Ｇの側方に設けられた筐体として示されているが、支持体Ｃは、規制部材８１を移動可能に支持することができれば、特にその形状や構造は限定されず、板状体等であってもよい。
In this embodiment, the restricting member 81 is movably provided on the support C, as shown in FIGS. 3 to 9. FIG. In this embodiment, the support C is shown as a housing provided on the side of the guide member G, as shown in FIGS. As long as it can be supported as much as possible, its shape and structure are not particularly limited, and it may be a plate-like body or the like.
規制部材８１は、規制位置と退避位置との間で移動可能であり、昇降部材４の被係合部４２ａと係合して昇降部材４の降下を規制することが可能であれば特にその形状は限定されない。たとえば、本実施形態では、規制部材８１は、細長い板状に構成されているが、規制部材８１に加わる荷重を支持することが可能なロッド状など、他の形状であってもよい。規制部材８１は、規制位置にあるときに、昇降部材４の降下を規制するように、昇降部材４により規制部材８１に加わる荷重を支持することができる剛性を有し、支持体Ｃに取り付けられている。
The regulating member 81 is movable between the regulating position and the retracted position. is not limited. For example, in the present embodiment, the restricting member 81 has an elongated plate shape. The regulating member 81 has rigidity capable of supporting the load applied to the regulating member 81 by the elevating member 4 so as to regulate the descent of the elevating member 4 when it is in the regulating position, and is attached to the support body C. ing.
また、本実施形態では、規制部材８１は、支持体Ｃに対して回転軸Ａｘ周りに回転するように取り付けられ、規制位置と退避位置との間を移動するように構成されている。しかし、規制部材８１は、昇降部材４の降下を規制することができれば、たとえば、水平方向に直線的に進退することにより規制位置と退避位置との間を移動するものであってもよい。また、本実施形態では、規制部材８１は、規制位置において、規制部材８１が回転軸Ａｘから先端に向って鉛直に延びた状態に対して、規制部材８１の先端が昇降部材４に向かって近付き、規制部材８１の先端が回転軸Ａｘよりも上方に位置するように傾斜した状態で保持されるように構成されている。この場合、規制部材８１が水平に保持される場合と比較して、昇降部材４から加わる荷重に対する耐性が高まり、規制部材８１の変形を抑制することができる。また、規制部材８１が支持体Ｃに対して回転軸Ａｘ周りに回転するように構成されている場合、操作ユニットＵの内部でロッド状の規制部材を水平方向に往復移動させて昇降部材４の降下を規制する構造と比較して、規制部材８１の移動に必要な操作ユニットＵの内部での水平方向のスペースを小さくすることができる。したがって、操作ユニットＵの水平方向の幅を小さくすることができ、入浴中に操作ユニットＵが邪魔になることが抑制される。
Further, in this embodiment, the restricting member 81 is attached to the support C so as to rotate about the rotation axis Ax, and is configured to move between the restricting position and the retracted position. However, as long as the regulating member 81 can regulate the descent of the lifting member 4 , the regulating member 81 may move between the regulating position and the retracted position by linearly advancing and retreating in the horizontal direction, for example. In the present embodiment, the regulation member 81 extends vertically from the rotation axis Ax toward the distal end of the regulation member 81 at the regulation position, whereas the regulation member 81 extends vertically toward the distal end of the regulation member 81 . , the tip of the regulating member 81 is held in an inclined state so as to be positioned above the rotation axis Ax. In this case, compared with the case where the regulation member 81 is held horizontally, the resistance to the load applied from the lifting member 4 is increased, and the deformation of the regulation member 81 can be suppressed. Further, when the restricting member 81 is configured to rotate about the rotation axis Ax with respect to the support C, the rod-shaped restricting member is reciprocated in the horizontal direction inside the operation unit U to move the lifting member 4. The horizontal space inside the operation unit U required for movement of the restricting member 81 can be reduced compared to a structure that restricts the descent. Therefore, the horizontal width of the operation unit U can be reduced, and the operation unit U is prevented from becoming an obstacle during bathing.
本実施形態では、連結部材９は規制機構８と接続し、規制機構８は、連結部材９の移動に応じて規制部材８１を規制位置と退避位置との間で移動させる。具体的には、規制機構８は、連結部材９の移動に応じて規制部材８１を移動させる補助部材８２を有している。本実施形態では、連結部材９が閉弁位置に位置する際は、補助部材８２は規制部材８１を規制位置に位置付け、連結部材９が開弁位置に位置する際には、補助部材８２は規制部材８１を退避位置に移動させる。補助部材８２は、連結部材９に直接または間接的に接続され、連結部材９の移動に連動させて規制部材８１を移動させるように規制部材８１に直接または間接的に接続される。なお、本実施形態では、補助部材８２は、一端が操作部ＯＰ１（または被作動部ＯＰ２）に取り付けられ、操作部ＯＰ１を介して連結部材９に接続され、他端が規制部材８１に接続されている。しかし、補助部材８２は、直接連結部材９に接続されていてもよいし、規制部材８１に間接的に接続されていてもよい。本実施形態では、連結部材９が上側に移動すると規制部材８１が退避位置に向かって移動するように補助部材８２に引っ張られ、連結部材９が下側に移動すると規制部材８１が規制位置に向かって押し出されるように、補助部材８２の他端は、規制部材８１の回転軸Ａｘと規制部材８１の先端との間の中間位置で規制部材８１に接続されている。具体的には、補助部材８２の一端の位置が規制部材８１の回転軸Ａｘの位置よりも昇降部材４に対して水平方向で遠くなるように、補助部材８２の一端が配置されている。また、補助部材８２の他端の位置が規制部材８１の回転軸Ａｘの位置よりも昇降部材４に対して水平方向で近くなるように、補助部材８２の他端が配置されている。
In this embodiment, the connecting member 9 is connected to the regulating mechanism 8 , and the regulating mechanism 8 moves the regulating member 81 between the regulating position and the retracted position in accordance with the movement of the connecting member 9 . Specifically, the regulating mechanism 8 has an auxiliary member 82 that moves the regulating member 81 according to the movement of the connecting member 9 . In this embodiment, when the connecting member 9 is positioned at the valve closing position, the auxiliary member 82 positions the restricting member 81 at the restricting position, and when the connecting member 9 is positioned at the valve opening position, the auxiliary member 82 restricts The member 81 is moved to the retracted position.

In this embodiment, the auxiliary member 82 has one end attached to the operating portion OP1 (or the operated portion OP2), connected to the connecting member 9 via the operating portion OP1, and connected to the restricting member 81 at the other end. ing. However, the auxiliary member 82 may be directly connected to the connecting member 9 or indirectly connected to the restricting member 81 . In this embodiment, when the connecting member 9 moves upward, the restricting member 81 is pulled by the auxiliary member 82 so as to move toward the retracted position, and when the connecting member 9 moves downward, the restricting member 81 moves toward the restricting position. The other end of the auxiliary member 82 is connected to the regulating member 81 at an intermediate position between the rotation axis Ax of the regulating member 81 and the tip of the regulating member 81 so as to be pushed out. Specifically, one end of the auxiliary member 82 is arranged so that the position of the one end of the auxiliary member 82 is horizontally farther from the elevation member 4 than the position of the rotation axis Ax of the regulating member 81 . Further, the other end of the auxiliary member 82 is arranged so that the position of the other end of the auxiliary member 82 is closer to the lifting member 4 in the horizontal direction than the position of the rotation axis Ax of the regulating member 81 .
本実施形態では補助部材８２はコイルバネ等の弾性体により構成されている。弾性体により構成された補助部材８２は、規制部材８１が昇降部材４と係合していない状態で、連結部材９の移動に応じて規制部材８１を退避位置へ移動させることが可能な弾性力を有していればよい。なお、補助部材８２は、連結部材９の移動に応じて規制部材８１を移動させることができれば、その構造や形状は特に限定されない。たとえば、補助部材８２は、連結部材９の移動を規制部材８１の回転運動に変換する伝動機構などであってもよい。
In this embodiment, the auxiliary member 82 is composed of an elastic body such as a coil spring. The auxiliary member 82 made of an elastic body has an elastic force capable of moving the regulating member 81 to the retracted position in accordance with the movement of the connecting member 9 when the regulating member 81 is not engaged with the lifting member 4 . should have The structure and shape of the auxiliary member 82 are not particularly limited as long as the restricting member 81 can be moved according to the movement of the connecting member 9 . For example, the auxiliary member 82 may be a transmission mechanism or the like that converts movement of the connecting member 9 into rotational movement of the restricting member 81 .
また、昇降部材４は、図３～図９に示されるように、下側から上昇するときに規制部材８１を押圧して規制部材８１を退避位置へと移動させる押圧部４２ｂを有している。押圧部４２ｂは、図３および図４に示されるように、昇降部材４が上昇移動する際に、昇降部材４の上昇方向の移動により、規制部材８１を押圧し、退避位置側へと移動させるように構成されている。押圧部４２ｂおよび規制部材８１の押圧部４２ｂとの当接箇所は、押圧部４２ｂが規制部材８１に当接して上昇移動したときに、押圧部４２ｂから規制部材８１に加わる力が、規制部材８１を退避位置側に移動させる方向の成分を有するように構成されている。なお、昇降部材４が上昇移動する際に規制部材８１が押圧部４２ｂにより退避位置側へ移動するものであれば、押圧部４２ｂおよび規制部材８１の構造は限定されない。押圧部４２ｂは、本実施形態では、案内部材Ｇに沿って移動する移動体４２に設けられているが、押圧部４２ｂにより規制部材８１を押圧して退避位置側へ移動させることができれば、たとえば、座面などの昇降本体４１など、昇降部材４を構成する他の部材に設けられていてもよい。
3 to 9, the elevating member 4 has a pressing portion 42b that presses the regulating member 81 to move the regulating member 81 to the retracted position when ascending from below. . As shown in FIGS. 3 and 4, when the elevating member 4 moves upward, the pressing portion 42b presses the restricting member 81 and moves it toward the retracted position as the elevating member 4 moves upward. is configured as When the pressing portion 42b contacts the regulating member 81 and moves upward, the force applied from the pressing portion 42b to the regulating member 81 is applied to the regulating member 81. to the retracted position side. The structures of the pressing portion 42b and the restricting member 81 are not limited as long as the pressing portion 42b moves the restricting member 81 toward the retracted position when the lifting member 4 moves upward. In this embodiment, the pressing portion 42b is provided on the moving body 42 that moves along the guide member G. , the lifting body 41 such as the seat surface, and other members that constitute the lifting member 4 .
昇降部材４が押圧部４２ｂを有していることにより、駆動部３１に流体が供給されて昇降部材４が規制部材８１の位置まで上昇したときに、図３および図４に示されるように、押圧部４２ｂが規制部材８１を押圧して退避位置側へと移動させる。退避位置側に規制部材８１が移動することにより、昇降部材４が規制部材８１よりも下側から上側へ上昇する場合に、規制部材８１が規制位置に突出していても、昇降部材４は規制部材８１により移動を妨げられることがなく、規制部材８１を押し退けてそのまま上昇することができる。
Since the lifting member 4 has the pressing portion 42b, when the fluid is supplied to the driving portion 31 and the lifting member 4 rises to the position of the regulating member 81, as shown in FIGS. The pressing portion 42b presses the restricting member 81 to move it toward the retracted position. When the regulating member 81 moves to the retracted position side and the lifting member 4 rises from below the regulating member 81 to above, even if the regulating member 81 protrudes to the regulating position, the lifting member 4 does not move toward the regulating member. The movement is not hindered by the 81, and the regulating member 81 can be pushed aside to move upward.
なお、本実施形態では、規制部材８１は、補助部材８２により規制位置側に押圧されている。そのため、昇降部材４により退避位置側へと移動した規制部材８１は、昇降部材４が規制部材８１を乗り越えた後に、補助部材８２により再び規制位置側へと戻る。そのため、流体の駆動部３１への供給が可能な状態で、昇降部材４が規制部材８１を乗り越える前後で、規制部材８１が規制位置に位置付けられているため、昇降部材４の降下による事故などを防ぐことができる。また、昇降部材４が上昇した後に、規制部材８１を規制位置に移動させる操作をその都度行う必要がなく、操作性が向上する。
In addition, in this embodiment, the restricting member 81 is pressed toward the restricting position by the auxiliary member 82 . Therefore, the regulating member 81 moved to the retracted position side by the lifting member 4 returns to the regulating position side again by the auxiliary member 82 after the lifting member 4 climbs over the regulating member 81 . Therefore, before and after the elevating member 4 climbs over the regulating member 81 in a state in which the fluid can be supplied to the drive unit 31, the regulating member 81 is positioned at the regulating position. can be prevented. Further, it is not necessary to perform an operation to move the restricting member 81 to the restricting position each time after the lifting member 4 is lifted, which improves the operability.
また、本実施形態では、規制機構８が連結部材９の移動に応じて規制部材８１を移動させる補助部材８２を有しているため、昇降部材４を降下させる際に、補助部材８２により規制部材８１が退避位置に移動し、昇降部材４を上昇させる際には、昇降部材４の押圧部４２ｂが規制部材８１を押圧して退避位置へと移動させるため、昇降部材４の昇降操作がシンプルとなる。
Further, in the present embodiment, since the regulation mechanism 8 has the auxiliary member 82 that moves the regulation member 81 in accordance with the movement of the connecting member 9, the auxiliary member 82 moves the regulation member when the lifting member 4 is lowered. 81 is moved to the retracted position and the lifting member 4 is lifted, the pressing portion 42b of the lifting member 4 presses the regulating member 81 to move it to the retracted position. Become.
本実施形態では、押圧部４２ｂと被係合部４２ａとは、案内部材Ｇが延びる方向に沿って移動する移動体４２に設けられている。規制部材８１は、案内部材Ｇに対して所定の距離となるように配置された支持体Ｃに設けられ、規制位置にある規制部材８１は案内部材Ｇに対して位置が定まっている。したがって、昇降部材４の上昇時および降下時に規制部材８１と当接する移動体４２の被係合部４２ａおよび押圧部４２ｂの、規制部材８１に対する位置が定まる。そのため、昇降部材４の降下時に被係合部４２ａの規制部材８１との係合が確実となり、昇降部材４の上昇時に押圧部４２ｂの規制部材８１との当接が確実となり、規制部材８１を退避位置側に円滑に移動させることができる。また、被係合部４２ａおよび押圧部４２ｂの両方が移動体４２に設けられているので、昇降部材４の構造がシンプルとなり、部品点数が少なくなる。
In this embodiment, the pressing portion 42b and the engaged portion 42a are provided on the moving body 42 that moves along the direction in which the guide member G extends. The regulating member 81 is provided on the support C arranged at a predetermined distance from the guide member G, and the regulating member 81 at the regulating position has a fixed position with respect to the guide member G. As shown in FIG. Therefore, the positions of the engaged portion 42a and the pressing portion 42b of the moving body 42 that contact the restricting member 81 when the elevating member 4 is raised and lowered relative to the restricting member 81 are determined. Therefore, when the elevating member 4 is lowered, the engaged portion 42a is reliably engaged with the regulating member 81, and when the elevating member 4 is raised, the pressing portion 42b is reliably brought into contact with the regulating member 81, thereby moving the regulating member 81. It can be smoothly moved to the retracted position side. In addition, since both the engaged portion 42a and the pressing portion 42b are provided on the moving body 42, the structure of the lifting member 4 is simplified and the number of parts is reduced.
また、本実施形態では、押圧部４２ｂと作動部４２ｃとの両方が、移動体４２に設けられている。案内部材Ｇに案内され位置決めされた移動体４２に押圧部４２ｂおよび作動部４２ｃが設けられていることにより、規制部材８１の退避位置側への移動と、被作動部ＯＰ２の作動とを確実に行うことができる。なお、押圧部４２ｂと作動部４２ｃとは、本実施形態では、別々の箇所に設けられているが、移動体４２の同一の部位としてもよい。
Further, in the present embodiment, both the pressing portion 42b and the operating portion 42c are provided on the moving body 42. As shown in FIG. Since the moving body 42 guided and positioned by the guide member G is provided with the pressing portion 42b and the operating portion 42c, the movement of the regulating member 81 to the retracted position side and the operation of the operated portion OP2 are ensured. It can be carried out. Although the pressing portion 42b and the operating portion 42c are provided at separate locations in the present embodiment, they may be provided at the same portion of the moving body 42. FIG.
また、規制部材８１は、本実施形態では、先端側に昇降部材４の被係合部４２ａと係合する係合部８１ａを有している。本実施形態では、図８に示されるように、昇降部材４の被係合部４２ａと、係合部８１ａとは、昇降部材４が規制部材８１に支持されているときに、規制部材８１が規制位置から退避位置へ移動することを抑制するように係合する。これにより、たとえば、供給路５、排出路６、駆動部３１、排出弁７などが破損したり、供給路５や排出路６の接続部分が外れたりして駆動部３１に供給された流体が漏れてしまった場合など、規制部材８１が規制位置になければ昇降部材４が降下してしまう状態において、規制部材８１が退避位置に移動することが抑制される。したがって、上述したような駆動部３１に供給された流体が漏れてしまった場合のような状態で、操作部ＯＰ１の操作により規制部材８１が退避位置に移動して昇降部材４が降下してしまうことを抑制することができる。
In addition, in this embodiment, the restricting member 81 has an engaging portion 81a that engages with the engaged portion 42a of the lifting member 4 on the distal end side. In the present embodiment, as shown in FIG. 8, the engaged portion 42a and the engaging portion 81a of the elevating member 4 are arranged so that when the elevating member 4 is supported by the regulating member 81, the regulating member 81 is engaged. It engages so as to suppress movement from the restricted position to the retracted position. As a result, for example, the supply passage 5, the discharge passage 6, the driving portion 31, the discharge valve 7, etc. may be damaged, or the connecting portions of the supply passage 5 and the discharge passage 6 may be disconnected, and the fluid supplied to the driving portion 31 may be lost. In the case where the regulation member 81 is not in the regulation position, the movement of the regulation member 81 to the retracted position is suppressed in a state where the lifting member 4 is lowered, such as when the regulation member 81 is in the regulation position. Therefore, in a state where the fluid supplied to the driving portion 31 leaks as described above, the operation of the operating portion OP1 causes the restricting member 81 to move to the retracted position and the lifting member 4 to descend. can be suppressed.
本実施形態では、被係合部４２ａは筒状の移動体４２から支持体Ｃに向かって突出した突出部の下端に設けられた凹部である。しかし、被係合部４２ａは、規制部材８１が規制位置から退避位置へ移動することを抑制するように係合することができれば、被係合部４２ａの形状や構造は特に限定されない。
In this embodiment, the engaged portion 42a is a concave portion provided at the lower end of a projecting portion projecting from the cylindrical moving body 42 toward the support C. As shown in FIG. However, the shape and structure of the engaged portion 42a are not particularly limited as long as the engaged portion 42a can be engaged so as to prevent the restricting member 81 from moving from the restricting position to the retracted position.
また、本実施形態では、規制機構８は、規制部材８１が昇降部材４の移動を規制した状態で、連結部材９が規制部材８１に対して相対移動を許容する移動許容機構Ｍを有している。この場合、操作部ＯＰ１の操作によって連結部材９が規制部材８１に対して相対移動し、規制部材８１が昇降部材４の移動を規制した状態が保たれる。より具体的には、規制部材８１が昇降部材４を支持している際に、連結部材９のみが規制部材８１に対して相対移動するため、規制部材８１が退避位置に移動しにくくなる。そのため、たとえば、規制部材８１が被係合部４２ａと係合している場合において、使用者が操作部ＯＰ１を操作したとしても、規制部材８１は昇降部材４の移動を規制した状態を保つことができる。したがって、駆動部３１に供給された流体が漏れてしまった場合など、規制部材８１が昇降部材４の降下などを規制する必要がある状態において、規制部材８１が退避位置に移動することを抑制し、昇降部材４が降下してしまうことを抑制することができる。また、操作部ＯＰ１を操作しても、連結部材９が規制部材８１に対して相対的に移動し、規制部材８１の移動は抑制されている。したがって、規制部材８１が被係合部４２ａと係合している状態で無理に操作部ＯＰ１が操作されて、規制部材８１や規制部材８１と接続された他の部材などが破損することが抑制される。
In addition, in the present embodiment, the restriction mechanism 8 has a movement permitting mechanism M that allows the connecting member 9 to move relative to the restriction member 81 while the restriction member 81 restricts the movement of the lifting member 4. there is In this case, the connecting member 9 moves relative to the restricting member 81 by operating the operating part OP1, and the state in which the restricting member 81 restricts the movement of the lifting member 4 is maintained. More specifically, when the regulating member 81 supports the lifting member 4, only the connecting member 9 moves relative to the regulating member 81, making it difficult for the regulating member 81 to move to the retracted position. Therefore, for example, when the regulating member 81 is engaged with the engaged portion 42a, even if the user operates the operating portion OP1, the regulating member 81 maintains the state in which the movement of the lifting member 4 is regulated. can be done. Therefore, in a state where the regulation member 81 needs to regulate the descent of the elevating member 4, such as when the fluid supplied to the drive unit 31 leaks, the movement of the regulation member 81 to the retracted position is suppressed. , it is possible to suppress the lifting member 4 from descending. Further, even if the operating portion OP1 is operated, the connecting member 9 moves relative to the restricting member 81, and the movement of the restricting member 81 is suppressed. Therefore, it is possible to prevent damage to the regulating member 81 and other members connected to the regulating member 81 by forcibly operating the operating portion OP1 while the regulating member 81 is engaged with the engaged portion 42a. be done.
なお、本実施形態では、移動許容機構Ｍは補助部材８２が弾性体であることにより構成されている。補助部材８２がコイルバネ等の弾性体により構成されている場合、操作部ＯＰ１が操作されると、弾性体である補助部材８２が伸長して規制部材８１に加わる力を緩和する。これにより、規制部材８１による昇降部材４の移動の規制が解除されにくくなるとともに、規制部材８１や規制部材８１に接続された他の部材の破損を抑制することができる。
In addition, in this embodiment, the movement permitting mechanism M is configured such that the auxiliary member 82 is an elastic body. When the auxiliary member 82 is made of an elastic body such as a coil spring, the elastic auxiliary member 82 expands to relieve the force applied to the restricting member 81 when the operation part OP1 is operated. As a result, the regulation of movement of the lifting member 4 by the regulation member 81 is less likely to be released, and damage to the regulation member 81 and other members connected to the regulation member 81 can be suppressed.
つぎに、図３～図９を参照し、本実施形態の昇降装置１の使用方法の一例について説明する。なお、本発明の昇降装置は、以下の使用方法に限定されるものではない。
Next, an example of how to use the lifting device 1 of the present embodiment will be described with reference to FIGS. 3 to 9. FIG. In addition, the lifting device of the present invention is not limited to the following usage.
まず、図２に示されるように、駆動部３１が収縮した状態の昇降装置１を浴槽Ｂａに設置する。本実施形態では、取り付け部Ａを浴槽Ｂａの上縁Ｅに取り付けることにより、昇降装置１が浴槽Ｂａに取り付けられている。このとき、規制部材８１は規制位置に位置し、操作部ＯＰ１が操作されておらず、被作動部ＯＰ２は作動しておらず、排出弁７は閉鎖した状態である。
First, as shown in FIG. 2, the lifting device 1 with the driving portion 31 contracted is installed in the bathtub Ba. In this embodiment, the lifting device 1 is attached to the bathtub Ba by attaching the attachment portion A to the upper edge E of the bathtub Ba. At this time, the regulating member 81 is positioned at the regulating position, the operating portion OP1 is not operated, the operated portion OP2 is not operating, and the discharge valve 7 is closed.
流体供給源である蛇口２を操作して水を供給すると、水は供給路５、流通ポート３２を経由して駆動部３１の充填部Ｆに供給される。充填部Ｆに水が供給されると、水量に応じて駆動部３１の蛇腹部３１ａが伸長し、蛇腹部３１ａの伸長に伴い、昇降本体４１が上昇する。昇降本体４１が上昇すると、昇降本体４１に接続部４３を介して接続された移動体４２が案内部材Ｇに沿って上昇する。
When water is supplied by operating the faucet 2 as a fluid supply source, the water is supplied to the filling portion F of the driving portion 31 via the supply channel 5 and the circulation port 32 . When water is supplied to the filling portion F, the bellows portion 31a of the drive portion 31 expands according to the amount of water, and the elevating main body 41 rises as the bellows portion 31a expands. When the elevating body 41 rises, the movable body 42 connected to the elevating body 41 via the connecting portion 43 rises along the guide member G. As shown in FIG.
移動体４２が案内部材Ｇに沿って上昇していき、入浴者が着座する着座高さの手前で、移動体４２の押圧部４２ｂは、図３に示されるように、規制位置に突出した状態の規制部材８１の下面と接触する。この状態からさらに昇降本体４１および移動体４２が上昇すると、押圧部４２ｂも上側に移動することにより、規制位置に位置する規制部材８１は、図４に示されるように、押圧部４２ｂにより回転軸Ａｘを中心として退避位置に向かって押し出されるように回転する。
As the moving body 42 rises along the guide member G, the pressing portion 42b of the moving body 42 protrudes to the regulated position as shown in FIG. contact with the lower surface of the regulating member 81 of . When the lifting body 41 and the moving body 42 are further raised from this state, the pressing portion 42b is also moved upward, so that the regulating member 81 positioned at the regulating position is rotated by the pressing portion 42b as shown in FIG. Rotate around Ax so as to be pushed toward the retracted position.
昇降本体４１がさらに上昇し、押圧部４２ｂが上下方向で規制部材８１を乗り越えると、退避位置側に移動した規制部材８１は、補助部材８２により、再度規制位置に押し戻される。昇降本体４１がさらに上昇すると、図５に示されるように、移動体４２の作動部４２ｃが被作動部ＯＰ２の先端部に当接する。昇降本体４１はこの時点で、入浴者が着座できる所定の高さ位置まで到達するが、蛇口２からの水の供給を停止しない場合、駆動部３１の蛇腹部３１ａはさらに伸長しようとする。このとき、蛇腹部３１ａの伸長に伴い昇降本体４１および移動体４２はさらに上昇し、図６に示されるように、移動体４２の作動部４２ｃが被作動部ＯＰ２を押し上げ、被作動部ＯＰ２は移動体４２とともに上側に移動する。被作動部ＯＰ２が上側に移動すると、被作動部ＯＰ２と接続された連結部材９が、バネ（付勢部材）Ｓ１の付勢力に抗して上側に引き上げられ、筒状部材７１の内部の管状部材７２の上端と筒状部材７１の上面（弁体Ｖ）との間に隙間が生じる。これにより、排出弁７が開放し、駆動部３１の充填部Ｆの水が、第２排出路６２、および管状部材７２を介して筒状部材７１の内部で管状部材７２の外側となる排出室ＣＨ内に流れ込み、排出室ＣＨから排出口Ｏ１を経由して第１排出路６１へと排出される。したがって、駆動部３１に過剰な水が供給されることが抑制され、駆動部３１の蛇腹部３１ａや、駆動部３１と供給路５や排出路６との接合部などの変形や破損を抑制することができる。また、被作動部ＯＰ２が押し上げられることにより排出弁７が開放して、昇降本体４１を所定の着座高さの範囲に位置させることができる。
When the elevating body 41 further rises and the pressing portion 42b climbs over the regulating member 81 in the vertical direction, the regulating member 81 moved to the retracted position is pushed back to the regulating position by the auxiliary member 82 again. When the elevating body 41 is further raised, the actuating portion 42c of the moving body 42 comes into contact with the distal end portion of the actuated portion OP2, as shown in FIG. At this point, the elevating body 41 reaches a predetermined height where the bather can sit, but if the water supply from the faucet 2 is not stopped, the bellows portion 31a of the driving portion 31 will continue to expand. At this time, as the bellows portion 31a expands, the elevating body 41 and the movable body 42 further rise, and as shown in FIG. It moves upward together with the moving body 42 . When the actuated portion OP2 moves upward, the connecting member 9 connected to the actuated portion OP2 is pulled upward against the biasing force of the spring (biasing member) S1, and the tubular member 71 inside the cylindrical member 71 moves upward. A gap is generated between the upper end of the member 72 and the upper surface (valve V) of the tubular member 71 . As a result, the discharge valve 7 is opened, and the water in the filling portion F of the driving portion 31 flows through the second discharge passage 62 and the tubular member 72 inside the tubular member 71 to the outside of the tubular member 72 . It flows into the CH and is discharged from the discharge chamber CH to the first discharge passage 61 via the discharge port O1. Therefore, excessive supply of water to the driving portion 31 is suppressed, and deformation and breakage of the bellows portion 31a of the driving portion 31 and joint portions between the driving portion 31 and the supply channel 5 and the discharge channel 6 are suppressed. be able to. Further, the discharge valve 7 is opened by pushing up the actuated part OP2, and the elevating body 41 can be positioned within a predetermined seating height range.
その後、蛇口２からの水の供給を停止すると、昇降本体４１は所定の着座高さ（図５に示す位置または図５と図８との間の高さ）で停止して、入浴者を昇降本体４１に乗せる準備が完了する。入浴者を昇降本体４１に乗せると、通常は、入浴者の体重により、昇降本体４１はわずかに降下するが、移動体４２の被係合部４２ａは、規制部材８１に対して上下方向に離間した位置で停止する。一方、たとえば、蛇腹部３１ａ、供給路５、第２排出路６２などに孔が開いていたり、排出弁７が破損している場合、供給路５や排出路６の接続部分が外れている場合、蛇腹部３１ａに供給される水の量が少ない場合、誤って操作部ＯＰ１を操作して排出弁７が開放している場合などには、昇降本体４１は下方に向かって降下する可能性がある。本実施形態では、このような場合であっても、規制部材８１が規制位置に位置しているため、図８に示されるように、昇降本体４１が降下したとしても、規制部材８１と移動体４２の被係合部４２ａとが係合して、昇降本体４１の降下が所定範囲に制限される。したがって、入浴者は安心して昇降本体４１に乗ることができ、仮に入浴者が昇降本体４１に乗った際に昇降本体４１が降下する状態であったとしても、規制部材８１の位置で昇降本体４１が留まるため、昇降本体４１の降下によって入浴者がバランスを崩したり、不安を覚えることが抑制される。
After that, when the water supply from the faucet 2 is stopped, the elevating body 41 stops at a predetermined seating height (the position shown in FIG. 5 or the height between FIGS. 5 and 8) to lift the bather. The preparation to put on the main body 41 is completed. When a bather is placed on the lifting body 41, the lifting body 41 normally descends slightly due to the weight of the bather. stop at the position On the other hand, for example, when the bellows portion 31a, the supply passage 5, the second discharge passage 62, etc. are perforated, the discharge valve 7 is damaged, or the connecting portion of the supply passage 5 or the discharge passage 6 is disconnected. If the amount of water supplied to the bellows portion 31a is small, or if the operation portion OP1 is erroneously operated to open the discharge valve 7, the elevation body 41 may move downward. be. In this embodiment, even in such a case, since the restricting member 81 is positioned at the restricting position, as shown in FIG. 42 is engaged with the engaged portion 42a, and the descent of the elevating body 41 is limited to a predetermined range. Therefore, the bather can safely get on the lift body 41, and even if the lift body 41 is lowered when the bather gets on the lift body 41, the lift body 41 is kept at the position of the regulating member 81. As a result, the bather is prevented from losing balance or feeling uneasy due to the descent of the elevating body 41.例文帳に追加
入浴者が昇降本体４１に乗り、入浴準備が完了すると、入浴者が浴槽Ｂａ内のお湯に浸かるために、昇降本体４１を降下させる。昇降本体４１を降下させるためには、入浴者または入浴を補助する補助者が、操作部ＯＰ１を操作する。図７に示されるように、操作部ＯＰ１を操作すると、連結部材９が上方に移動し、補助部材８２によって操作部ＯＰ１を介して連結部材９に接続された規制部材８１が連結部材９と連動して退避位置に移動する。これにより、昇降本体４１が降下するときに、移動体４２の被係合部４２ａが通る移動経路から規制部材８１が外れる。本実施形態では、操作部ＯＰ１が操作されると、コイルバネである補助部材８２によって規制部材８１が退避位置に向かって引っ張られることにより規制部材８１が退避位置に移動する。補助部材８２は、連結部材９に直接または間接的に接続して、規制部材８１を連結部材９の移動に連動させて移動させるので、規制部材８１が退避位置に位置する状態で、移動体４２を、規制部材８１と接触することなしに、規制部材８１が存在する高さ位置を通過させることができる。しかも、補助部材８２は、弾性を有するために、規制部材８１と移動体４２が係合した状態では、連結部材９が上方に移動することを許容するために、規制部材８１との係合により昇降本体４１の降下を抑制した状態で、排出弁７からの液体の排出を許容することができる。
When a bather gets on the elevating body 41 and completes preparation for bathing, the elevating body 41 is lowered so that the bather can soak in the hot water in the bathtub Ba. In order to lower the elevating main body 41, the bather or an assistant who assists in bathing operates the operation part OP1. As shown in FIG. 7, when the operating portion OP1 is operated, the connecting member 9 moves upward, and the restricting member 81 connected to the connecting member 9 via the operating portion OP1 by the auxiliary member 82 interlocks with the connecting member 9. to move to the retracted position. As a result, when the lifting body 41 descends, the restricting member 81 is removed from the moving path along which the engaged portion 42a of the moving body 42 passes. In the present embodiment, when the operating portion OP1 is operated, the restricting member 81 is pulled toward the retracted position by the auxiliary member 82, which is a coil spring, so that the restricting member 81 moves to the retracted position. The auxiliary member 82 is directly or indirectly connected to the connecting member 9 and moves the regulating member 81 in conjunction with the movement of the connecting member 9. can pass through the height position where the regulating member 81 exists without coming into contact with the regulating member 81 . Moreover, since the auxiliary member 82 has elasticity, when the restricting member 81 and the moving body 42 are engaged with each other, the connecting member 9 is allowed to move upward. It is possible to allow the liquid to be discharged from the discharge valve 7 while the descent of the elevating body 41 is suppressed.
操作部ＯＰ１が上側に操作されると、連結部材９がバネＳ１の付勢力に抗して弁体Ｖを上側に移動させ、管状部材７２の上端と弁体Ｖとの間に隙間が生じる。これにより、駆動部３１の充填部Ｆの水は、昇降本体４１側からの入浴者の体重による圧力により、第２排出路６２を経由して開放した管状部材７２の上端と弁体Ｖとの間の隙間を通過し、排出室ＣＨから排出口Ｏ１を経由して第１排出路６１に向かって排出され、昇降本体４１が降下する。このように、操作部ＯＰ１の操作により、規制部材８１の退避位置への移動と、排出弁７の操作の両方を行うことができ、昇降本体４１の降下動作が非常に簡単に行うことができる。
When the operating part OP1 is operated upward, the connecting member 9 moves the valve body V upward against the biasing force of the spring S1, and a gap is created between the upper end of the tubular member 72 and the valve body V. As a result, the water in the filling portion F of the drive portion 31 is pushed through the upper end of the tubular member 72 opened via the second discharge passage 62 and the valve body V by pressure due to the body weight of the bather from the elevator main body 41 side. It passes through the gap between them, is discharged from the discharge chamber CH through the discharge port O1 toward the first discharge passage 61, and the elevating main body 41 descends. In this manner, by operating the operating portion OP1, both the movement of the regulating member 81 to the retracted position and the operation of the discharge valve 7 can be performed, and the lowering operation of the elevating body 41 can be performed very easily. .
なお、たとえば、入浴者を昇降本体４１に乗せる過程などにおいて、上述のように、駆動部３１に供給された流体が漏れて昇降本体４１が規制部材８１に支持されて降下を規制されているときに、規制部材８１が退避位置に移動してしまうと、昇降本体４１が入浴者が昇降本体４１に乗る前に降下してしまう。本実施形態では、昇降本体４１が所定の量の降下をすると、規制部材８１の係合部８１ａと移動体４２の被係合部４２ａとが、規制部材８１の退避位置側への移動が抑制されるように係合する。この場合、規制部材８１が退避位置に移動することが抑制されるので、規制部材８１が規制位置に留まり、昇降本体４１の降下を防ぐことができる。また、本実施形態では、補助部材８２がコイルバネ等の弾性体であることにより、操作部ＯＰ１が操作されたとしても、補助部材８２が弾性変形して伸長することにより、操作部ＯＰ１による規制部材８１を退避位置側に移動させようとする力は、補助部材８２の変形により逃がされる。したがって、操作部ＯＰ１が強い操作力で操作されても、補助部材８２が弾性変形して、操作部ＯＰ１に加わる操作力が規制部材８１に伝わりにくくなる。そのため、係合部８１ａと被係合部４２ａとの係合が解除されにくくなり、規制部材８１の退避位置側への移動を抑制し、昇降本体４１が急激に降下することが抑制される。
For example, in the process of placing a bather on the elevating body 41, as described above, when the fluid supplied to the drive unit 31 leaks and the elevating body 41 is supported by the regulating member 81 and the descent is restricted. In addition, if the regulating member 81 moves to the retracted position, the elevating body 41 is lowered before the bather gets on the elevating body 41 . In this embodiment, when the elevating body 41 is lowered by a predetermined amount, the engaging portion 81a of the regulating member 81 and the engaged portion 42a of the moving body 42 suppress the movement of the regulating member 81 toward the retracted position. Engage so that In this case, since movement of the regulating member 81 to the retracted position is suppressed, the regulating member 81 remains at the regulating position, and the lifting body 41 can be prevented from descending. In addition, in the present embodiment, since the auxiliary member 82 is an elastic body such as a coil spring, even if the operation part OP1 is operated, the auxiliary member 82 is elastically deformed and elongated, so that the regulating member by the operation part OP1 The force that tends to move 81 toward the retracted position is relieved by the deformation of auxiliary member 82 . Therefore, even if the operating portion OP1 is operated with a strong operating force, the auxiliary member 82 is elastically deformed, and the operating force applied to the operating portion OP1 is less likely to be transmitted to the restricting member 81 . Therefore, the engagement between the engaging portion 81a and the engaged portion 42a is less likely to be released, suppressing the movement of the regulating member 81 to the retracted position side, and suppressing the rapid descent of the lifting body 41.
入浴者の入浴が完了すると、操作部ＯＰ１を操作して、排出弁７を閉鎖した後、蛇口２を操作することにより、再び駆動部３１の充填部Ｆに水を充填し、昇降本体４１を上昇させて、入浴者を昇降本体４１から下ろす。このときにおいても、規制部材８１は規制位置に位置しているため、昇降本体４１の降下が所定範囲に制限され、入浴者は安心して昇降本体４１から下りることができる。
When the bather finishes bathing, the operation part OP1 is operated to close the discharge valve 7, and then the faucet 2 is operated to fill the filling part F of the driving part 31 with water again, and the lift main body 41 is moved. It is lifted to lower the bather from the lifting body 41. - 特許庁Even at this time, since the regulating member 81 is positioned at the regulating position, the descent of the elevating body 41 is limited to a predetermined range, so that the bather can get off the elevating body 41 with peace of mind.
