The structures of the actuated member 9 and the actuating part 42c are not particularly limited as long as they are configured to open the discharge valve 7. The actuated member 9 may be actuated by the actuating portion 42c or may be manually operated directly. Further, in the present embodiment, the actuated member 9 moves the discharge valve 7 in the opening direction by rotating the actuated portion 91 about the rotation axis Ax1. The discharge valve 7 may be moved in the opening direction by moving.
作動部４２ｃは、被作動部材９に当接して、被作動部材９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の補助部４２に設けられているが、被作動部材９を作動させることができれば、昇降部材４の補助部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。補助部４２に作動部４２ｃが設けられている場合は、補助部４２が案内部材Ｇに沿って移動するため、補助部４２の被作動部材９に対する位置ずれが生じにくく、作動部４２ｃが被作動部材９に当接しやすくなる。

As described above, in the present embodiment, the lifting device 1 includes the regulation mechanism 8 having the regulation member 81 that moves between the regulation position and the retracted position, and when the elevation member 4 descends from the upper side, 4 has an engaged portion 42a that engages with the regulation member 81 located at the regulation position. Therefore, for example, when the fluid supplied to the drive unit 31 is discharged from the discharge valve 7 and the elevating member 4 tries to descend by the amount of the ejected fluid, the elevating member 4 is supported by the restricting member 81, and the elevating member 4 moves up and down. The member 4 can be prevented from falling. Accordingly, for example, when a person or an object is getting on or off the lifting member 4, it is possible to safely get on and off, and it is possible to eliminate the anxiety of a person such as a bather who rides on the lifting member 4 or an assistant. .. Further, for example, the supply passage 5, the discharge passage 6, the drive unit 31, the discharge valve 7 or the like is damaged, or the connection portion of the supply passage 5 or the discharge passage 6 is disconnected, so that the fluid supplied to the drive unit 31 leaks. If the lifting member 4 is lifted, it is suppressed that the lifting member 4 is lowered from the raised position. Therefore, it is possible to prevent the elevating member 4 from being lowered during the work of placing a person or an object on the elevating member 4, and it is possible to enhance the safety when the elevating device 1 is used.
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８２に移動可能に設けられている。支持体８２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８２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。

The shape and structure thereof are not particularly limited as long as they can be supported, and 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、ロッド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板状体や、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８２に取り付けられている。
The restricting member 81 is movable between a restricting position and a retracted position, and is particularly shaped as long as it can restrict the descent of the elevating member 4 by engaging with the engaged portion 42a of the elevating member 4.

For example, in the present embodiment, the regulation member 81 is configured in the shape of a rod, but may be a plate-like body capable of supporting the load applied to the regulation member 81, or another shape. The restricting member 81 has rigidity that can support the load applied to the restricting member 81 by the elevating member 4 so as to restrict the lowering of the elevating member 4 when in the restricting position, and is attached to the support body 82. ing.
また、本実施形態では、規制部材８１は、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、回転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、昇降装置１が取り付けられる浴槽Ｂａの内面に平行かつ水平方向に進退するように構成されているが、規制位置と退避位置との間で移動可能であれば、規制部材８１の移動方向は特に限定されず、たとえば、浴槽Ｂａの内面に垂直な方向に規制部材８１が進退してもよい。
Further, in the present embodiment, the regulation member 81 is configured to move between the regulation position and the retracted position by linearly advancing and retracting in the horizontal direction. However, the regulation member 81 may be one that moves between the regulation position and the retracted position by rotation, as long as it can regulate the lowering of the elevating member 4. Further, in the present embodiment, the regulation member 81 is configured to advance and retreat in the horizontal direction in parallel with the inner surface of the bathtub Ba to which the lifting device 1 is attached, but it is movable between the regulation position and the retracted position. If so, the movement direction of the regulation member 81 is not particularly limited, and for example, the regulation member 81 may advance and retreat in a direction perpendicular to the inner surface of the bathtub Ba.

In this embodiment, as shown in FIGS. 3 to 9, the regulation mechanism 8 has a guide portion 83 that guides the movement of the regulation member 81 between the regulation position and the retracted position. Since the regulation mechanism 8 has the guide portion 83, the regulation member 81 can move stably between the regulation position and the retracted position. Accordingly, when the restricting member 81 moves to the restricting position, the restricting member 81 is less likely to be displaced with respect to the engaged portion 42a of the elevating member 4, so that the engaging portion 42a is more reliably engaged. Can be The shape and structure of the guide portion 83 are not particularly limited as long as they can guide the movement of the restriction member 81. In the present embodiment, the guide portion 83 is provided on the support body 82 as a tubular body into which the regulation member 81 is inserted. The guide portion 83 does not need to cover the entire circumference of the regulation member 81, and may be a guide wall portion or a guide protrusion that covers a part of the outer circumference of the regulation member 81. In addition, it is preferable that the guide portion 83 has an abutting portion that abuts in a vertical direction (a direction in which a load is applied) on the outer periphery of the regulating member 81. In this case, the contact portion of the guide portion 83 can support the load applied to the regulation member 81 from the elevating member 4 by the guide portion 83. That is, the regulation mechanism 8 has a support portion that supports the load applied to the regulation member 81 by the elevating member 4, and a support member may be provided separately from the guide portion 83.

Further, in the present embodiment, as shown in FIGS. 3 to 9, the regulation member 81 is biased toward the regulation position side by the biasing member S2. In this case, the regulation member 81 can be moved to the retracted position by being positioned at the regulation position by the biasing member S2 and deforming the biasing member S2. In this case, the operation for moving the regulation member 81 to the regulation position becomes unnecessary. Although the biasing member S2 is a coil spring in the present embodiment, the biasing member S2 is not limited to the coil spring as long as it can bias the regulation member 81 toward the regulation position.
また、規制機構８は、図３〜図９に示されるように、規制位置に位置する規制部材８１を退避位置へと移動させる解除部材８４を有している。解除部材８４は、昇降部材４を降下させる場合などにおいて、規制部材８１を退避位置へと移動させる際に操作される（図７参照）。本実施形態では、解除部材８４は、操作部８５により操作され、規制部材８１を退避位置へと移動させている。なお、操作部８５は、本実施形態では、回転軸Ａｘ２周りに回転する操作レバーとして示されているが、操作部８５の形状や構造は特に限定されず、解除部材８４の構成に応じて適宜変更することができる。また、操作部８５は、本実施形態では、手動により操作されるように構成されているが、電動で操作されるものであってもよい。

The release member 84 is operated when the regulating member 81 is moved to the retracted position when the elevating member 4 is lowered (see FIG. 7). In the present embodiment, the release member 84 is operated by the operation portion 85 to move the restriction member 81 to the retracted position. Although the operating portion 85 is shown as an operating lever that rotates around the rotation axis Ax2 in the present embodiment, the shape and structure of the operating portion 85 is not particularly limited, and is appropriately changed according to the configuration of the release member 84. Can be changed. Further, although the operation unit 85 is configured to be manually operated in the present embodiment, it may be electrically operated.

The moving member 84a is moved in a direction parallel to the retracting direction of 81 (see FIG. 7). Due to the movement of the moving member 84a, the regulating member 81 moves to the retracted position side. The shapes and structures of the moving member 84a and the rotating member 84b are not limited to the illustrated shapes and structures as long as the regulating member 81 can be moved to the retracted position side.
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。本実施形態では、押圧部４２ｂおよび規制部材８１の先端部Ｔに傾斜面を有することにより、押圧部４２ｂと当接した規制部材８１が退避位置側へ移動するように構成されている。つまり、押圧部４２ｂは、表面に平滑面を有し、規制部材８１が押圧部４２ｂの平滑面と当接し、その平滑面上を規制部材８１がスライドしながら退避位置方向へ押圧し、昇降部材４が規制部材８１を越えて上昇できるようにする。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。たとえば、押圧部４２ｂのみが傾斜面を有していてもよいし、規制部材８１の先端部Ｔのみが傾斜面を有していてもよい。押圧部４２ｂは、本実施形態では、案内部材Ｇに沿って移動する補助部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。
Further, as shown in FIGS. 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 rising from the lower side. .. As shown in FIGS. 3 and 4, the pressing portion 42b presses the regulating member 81 by the movement of the elevating member 4 in the ascending direction when the elevating member 4 moves upward, and moves it to the retracted position side. Is configured. At the contact portion between the pressing portion 42b and the pressing member 42b of the restriction member 81, the force applied from the pressing portion 42b to the restriction member 81 when the pressing portion 42b contacts the restriction member 81 and ascends and moves. Is configured to have a component in the direction of moving the to the retracted position side. In the present embodiment, the pressing portion 42b and the tip end portion T of the regulating member 81 have inclined surfaces, so that the regulating member 81 contacting the pressing portion 42b is moved to the retracted position side. That is, the pressing portion 42b has a smooth surface, and the restricting member 81 contacts the smooth surface of the pressing portion 42b, and the restricting member 81 slides on the smooth surface to press the retracting position toward the elevating member. 4 is allowed to rise above the regulating member 81. The structures of the pressing portion 42b and the restricting member 81 are not limited as long as the restricting member 81 moves to the retracted position side by the pressing portion 42b when the elevating member 4 moves upward. For example, only the pressing portion 42b may have the inclined surface, or only the tip portion T of the regulating member 81 may have the inclined surface. In the present embodiment, the pressing portion 42b is provided on the auxiliary portion 42 that moves along the guide member G, but if the pressing portion 42b can press the regulating member 81 to move it to the retracted position side, for example, It may be provided on another member that constitutes the lifting member 4, such as the lifting body 41 such as a seat surface.
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 elevating member 4 has the pressing portion 42b, when fluid is supplied to the driving unit 31 and the elevating member 4 moves up to the position of the regulating member 81, as shown in FIGS. 3 and 4, The pressing portion 42b presses the regulating member 81 to move it to the retracted position side. When the elevating member 4 moves upward from below the restricting member 81 by moving the restricting member 81 to the retracted position side, even if the restricting member 81 protrudes to the restricting position, the elevating member 4 remains the restricting member. The movement is not hindered by 81, and the regulating member 81 can be pushed away and raised as it is.
なお、本実施形態では、規制部材８１は、付勢部材Ｓ２により規制位置側に付勢されている。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、付勢部材Ｓ２の付勢力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 this embodiment, the regulation member 81 is urged toward the regulation position by the urging member S2. Therefore, the regulating member 81 moved to the retracted position side by the elevating member 4 returns to the regulating position side again by the urging force of the urging member S2 after the elevating member 4 has passed over the regulating member 81. Therefore, in a state in which the fluid can be supplied to the drive unit 31, the restricting member 81 is positioned at the restricting position before and after the elevating member 4 gets over the restricting member 81. Can be prevented. Further, it is not necessary to perform the operation of moving the restricting member 81 to the restricting position each time after the elevating member 4 is lifted, and the operability is improved.
上述したように、本実施形態では、解除部材８４を有しているため、昇降部材４を降下させる際に、解除部材８４により規制部材８１を退避位置に移動させ、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。
As described above, in this embodiment, since the release member 84 is provided, when the lifting member 4 is lowered, when the release member 84 moves the restriction member 81 to the retracted position and raises the lifting member 4. In addition, since the pressing portion 42b of the elevating member 4 presses the regulating member 81 to move it to the retracted position, the elevating operation of the elevating member 4 becomes simple.
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補助部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Ｓ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と当接する補助部４２の被係合部４２ａおよび押圧部４２ｂの、規制部材８１の先端部Ｔ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の両方が補助部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 the present embodiment, the pressing portion 42b and the engaged portion 42a are provided in the auxiliary portion 42 that moves along the direction in which the guide member G extends. The regulating member 81 is provided on the support S arranged at a predetermined distance from the guiding member G, and the regulating member 81 in the regulating position is fixed in position with respect to the guiding member G. Therefore, the positions of the engaged portion 42a and the pressing portion 42b of the auxiliary portion 42, which come into contact with the regulating member 81 when the elevating member 4 moves up and down, are determined with respect to the tip T of the regulating member 81. Therefore, when the elevating member 4 is lowered, the engaged portion 42a is surely engaged with the regulating member 81, and when the elevating member 4 is raised, the pressing portion 42b is surely brought into contact with the regulating member 81, so that the regulating member 81 is moved. It can be smoothly moved to the retracted position side. Further, since both the engaged portion 42a and the pressing portion 42b are provided in the auxiliary portion 42, the structure of the elevating 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、補助部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補助部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、被作動部材９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、同一の傾斜面上に配置されているが、別々の箇所に設けてもよい。
Further, in the present embodiment, both the pressing portion 42b and the operating portion 42c are provided in the auxiliary portion 42. Since the auxiliary portion 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 member 9 are surely performed. It can be carried out. In addition, although the pressing portion 42b and the operating portion 42c are arranged on the same inclined surface in the present embodiment, they may be provided at different positions.
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、誤って解除部材８４を操作してしまうことを防ぐことができる。
Further, in the present embodiment, the regulation member 81 has an engaging portion 81a that engages with the engaged portion 42a of the elevating member 4 on the tip side. In the present embodiment, as shown in FIG. 8, the engaged portion 42a of the elevating member 4 and the engaging portion 81a are such that when the elevating member 4 is supported by the regulating member 81, the regulating member 81 is The engagement is performed so as to suppress the movement from the regulated position to the retracted position. As a result, for example, the supply path 5, the discharge path 6, the drive unit 31, the discharge valve 7 or the like is damaged, or the connection portion of the supply path 5 or the discharge path 6 is disconnected, so that the fluid supplied to the drive unit 31 is not supplied. When the elevating member 4 is lowered unless the regulation member 81 is at the regulation position, such as when it leaks, the regulation member 81 is prevented from moving to the retracted position. Therefore, it is possible to prevent erroneous operation of the release member 84 in a state where the fluid supplied to the drive unit 31 has leaked as described above.
本実施形態では、被係合部４２ａに係合突起Ｐａが設けられ、規制部材８１の係合部８１ａに係合凹部Ｐｂが設けられている。しかし、被係合部４２ａおよび係合部８１ａ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および係合部８１ａの凹凸は逆であってもよいし、他の係合構造であってもよい。係合突起Ｐａと係合凹部Ｐｂとは規制部材８１の移動方向において係合するので、この係合関係によって規制部材８１の退避位置方向への移動が規制される。
In the present embodiment, the engaged portion Pa is provided on the engaged portion 42a, and the engaging recess Pb is provided on the engaging portion 81a of the regulating member 81. However, if the engaged portion 42a and the engaging portion 81a can be engaged so as to suppress the movement of the regulating member 81 from the regulating position to the retracted position, the engaged portion 42a and the engaging portion 81a will not move. The concavities and convexities may be reversed, or another engagement structure may be used. Since the engagement protrusion Pa and the engagement recess Pb are engaged in the movement direction of the regulation member 81, the movement of the regulation member 81 in the retracted position direction is regulated by this engagement relationship.
また、本実施形態では、解除部材８４が、操作されることによって操作力を被作動部材９に伝達する伝達部８４ｃを有し、解除部材８４の操作によって、規制部材８１の退避位置への移動と被作動部材９の作動とが行われる。
Further, in the present embodiment, the releasing member 84 has the transmitting portion 84c that transmits the operating force to the actuated member 9 when operated, and the operation of the releasing member 84 moves the regulating member 81 to the retracted position. And the actuated member 9 is actuated.
伝達部８４ｃは、伝達部８４ｃが操作部８５によって操作されると被作動部材９に操作力を伝達し、被作動部材９を作動させる。これにより、解除部材８４の操作によって、規制部材８１の退避位置への移動と、被作動部材９の作動との両方を行うことができる。そのため、たとえば、入浴者が昇降部材４に乗った後、浴槽Ｂａの湯の中に昇降部材４を降下させる際や、入浴が完了した後に昇降装置１を片づける場合に昇降部材４を降下させる際などに、解除部材８４の単一の操作により、規制部材８１を退避位置に移動させて昇降部材４の降下を可能にしつつ、同時に流体を駆動部３１から排出して昇降部材４の効果を促進することができる。そのため、昇降装置１の操作性が向上する。
When the transmission portion 84c is operated by the operation portion 85, the transmission portion 84c transmits an operating force to the operated member 9 to activate the operated member 9. Thus, by operating the release member 84, both the movement of the restriction member 81 to the retracted position and the operation of the actuated member 9 can be performed. Therefore, for example, when the bather rides on the elevating / lowering member 4, the elevating / lowering member 4 is lowered when the elevating / lowering member 4 is lowered into the hot water of the bathtub Ba, or when the elevating / lowering device 1 is cleared after the bathing is completed. In this case, by operating the release member 84 by a single operation, the regulating member 81 is moved to the retracted position to allow the elevating member 4 to descend, and at the same time, the fluid is discharged from the drive unit 31 to bring about the effect of the elevating member 4. Can be promoted. Therefore, the operability of the lifting device 1 is improved.
伝達部８４ｃの構造は、解除部材８４による規制部材８１を退避位置側へ移動させる操作時に、被作動部材９を作動させることができれば特に限定されない。たとえば、図７に示されるように、伝達部８４ｃが回転することにより、伝達部８４ｃが被作動部材９と当接して、被作動部材９を作動方向に押圧するように伝達部８４ｃが構成されていればよい。本実施形態では、伝達部８４ｃは、回転軸Ａｘ２周りに回転するカムであり、伝達部８４ｃが回転することにより、レバー状の被作動部９１の底部と当接し、そのまま回転させると、被作動部９１が回転軸Ａｘ１周りに回転するように構成されている。伝達部８４ｃの回転により被作動部９１が回転して、連動部９２を介して排出弁７が開放方向に移動される。伝達部８４ｃの回転軸Ａｘ２は、解除部材８４の回転部材８４ｂの回転軸と同軸であり、操作部８５の回転により、伝達部８４ｃおよび回転部材８４ｂがともに回転軸Ａｘ２周りに同方向（図３〜図９における反時計回り）に回転する。これにより、被作動部材９および移動部材８４ａがともに動かされ、流体の排出と規制部材８１の退避位置側への移動の両方が行われる。また、本実施形態では、板状の移動部材８４ａと、レバー状の被作動部９１とは互いに略垂直方向に配置され、カム状の伝達部８４ｃおよびカム状の回転部材８４ｂは、移動部材８４ａおよび被作動部９１の配置に対応するように、所定の角度ずれるように配置されている。また、カム状の伝達部８４ｃの回転軸Ａｘ２からの長さは、カム状の回転部材８４ｂの回転軸Ａｘ２からの長さよりも短くなるように構成されている。しかし、伝達部８４ｃおよび回転部材８４ｂの角度や長さは特に限定されず、被作動部９１および移動部材８４ａの配置等に応じて適宜変更することができる。
The structure of the transmission portion 84c is not particularly limited as long as the actuated member 9 can be operated during the operation of moving the restriction member 81 by the release member 84 to the retracted position side. For example, as shown in FIG. 7, when the transmission portion 84c rotates, the transmission portion 84c contacts the actuated member 9 and the transmission portion 84c is configured to press the actuated member 9 in the operating direction. It should be. In the present embodiment, the transmission portion 84c is a cam that rotates around the rotation axis Ax2, and when the transmission portion 84c rotates, the transmission portion 84c comes into contact with the bottom portion of the lever-shaped operated portion 91, and when it is rotated as it is, it is operated. The portion 91 is configured to rotate around the rotation axis Ax1. The actuated portion 91 is rotated by the rotation of the transmission portion 84c, and the discharge valve 7 is moved in the opening direction via the interlocking portion 92. The rotation axis Ax2 of the transmission portion 84c is coaxial with the rotation axis of the rotation member 84b of the release member 84, and the rotation of the operation portion 85 causes both the transmission portion 84c and the rotation member 84b to rotate in the same direction around the rotation axis Ax2 (see FIG. 3). ~ Counterclockwise in Fig. 9). As a result, both the actuated member 9 and the moving member 84a are moved, and both the discharge of the fluid and the movement of the regulating member 81 to the retracted position side are performed. In addition, in the present embodiment, the plate-shaped moving member 84a and the lever-shaped operated portion 91 are arranged substantially perpendicular to each other, and the cam-shaped transmitting portion 84c and the cam-shaped rotating member 84b are the moving member 84a. And, they are arranged so as to be displaced by a predetermined angle so as to correspond to the arrangement of the operated portion 91. In addition, the length of the cam-shaped transmission portion 84c from the rotation axis Ax2 is shorter than the length of the cam-shaped rotation member 84b from the rotation axis Ax2. However, the angles and lengths of the transmission portion 84c and the rotating member 84b are not particularly limited, and can be appropriately changed depending on the arrangement of the operated portion 91 and the moving member 84a.
なお、本実施形態では、移動部材８４ａは弾性変形可能な板状体とすることが好ましい。たとえば、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には、昇降部材４が降下するため、規制部材８１の係合部８１ａと昇降部材４の被係合部４２ａとは係合する。このような場合に、移動部材８４ａが板バネ状の弾性変形可能な板状体であれば、操作部８５が操作されたとしても、被作動部材９は作動されるが、移動部材８４ａは回転部材８４ｂから押圧されたときに弾性変形して撓む。そのため、操作部８５および回転部材８４ｂにより、移動部材８４ａおよび規制部材８１を退避位置側に移動させようとする力は移動部材８４ａの弾性変形により逃がされる。したがって、係合部８１ａと被係合部４２ａとが係合しているときに、規制部材８１の退避位置側への移動を抑制することができ、昇降部材４が降下すべきではない状態において解除部材８４が操作部８５により操作された場合であっても、規制部材８１により昇降部材４を支持し続けることができる。
In addition, in the present embodiment, it is preferable that the moving member 84a is an elastically deformable plate-shaped body. For example, when the fluid supplied to the drive unit 31 as described above leaks, the elevating member 4 descends, so that the engaging portion 81a of the regulating member 81 and the engaged portion 42a of the elevating member 4 are Engage. In such a case, if the moving member 84a is a plate spring-like elastically deformable plate-shaped member, the operated member 9 is operated even if the operating portion 85 is operated, but the moving member 84a rotates. When pressed by the member 84b, it elastically deforms and bends. Therefore, the force that tries to move the moving member 84a and the regulating member 81 to the retracted position side by the operation portion 85 and the rotating member 84b is released by the elastic deformation of the moving member 84a. Therefore, when the engaging portion 81a and the engaged portion 42a are engaged, the movement of the regulating member 81 to the retracted position side can be suppressed, and the elevating member 4 should not descend. Even when the release member 84 is operated by the operation unit 85, the elevating member 4 can be continuously supported by the restriction member 81.
移動部材８４ａの材料は特に限定されないが、たとえば弾性変形可能な合成樹脂などにより形成することができる。本実施形態では、移動部材８４ａは、規制部材８１から片持ち式に延び、規制部材８１の基端側から、規制部材８１の軸方向に対して略垂直方向に延び、上下方向に細長い移動部材８４ａの一端側が規制部材８１に固定され、他端側は自由端となっている。本実施形態では、移動部材８４ａの他端側に、回転部材８４ｂが当接するように、移動部材８４ａが配置されている。
The material of the moving member 84a is not particularly limited, but can be formed of, for example, an elastically deformable synthetic resin. In the present embodiment, the moving member 84a extends in a cantilever manner from the regulating member 81, extends from the base end side of the regulating member 81 in a direction substantially perpendicular to the axial direction of the regulating member 81, and is a vertically elongated moving member. One end of 84a is fixed to the regulating member 81, and the other end is a free end. In the present embodiment, the moving member 84a is arranged on the other end side of the moving member 84a so that the rotating member 84b abuts.
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 a method of using the elevating device 1 of this embodiment will be described with reference to FIGS. 3 to 9. 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、レバー状の操作部８５は押し下げられた第１の位置にあり、規制部材８１は規制位置に位置し、被作動部材９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 drive unit 31 contracted is installed in the bathtub Ba. In the present 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 lever-shaped operation portion 85 is in the depressed first position, the regulating member 81 is in the regulating position, the operated member 9 is not activated, 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補助部４２が案内部材Ｇに沿って上昇する。
When water is supplied by operating the faucet 2 which is a fluid supply source, the water is supplied to the filling section F of the drive section 31 via the supply path 5 and the distribution port 32. When water is supplied to the filling part F, the bellows part 31a of the drive part 31 expands according to the amount of water, and the elevating body 41 rises as the bellows part 31a extends. When the elevating main body 41 rises, the auxiliary portion 42 connected to the elevating main body 41 via the connecting portion 43 rises along the guide member G.
補助部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、補助部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の先端部Ｔと接触する。この状態からさらに昇降本体４１および補助部４２が上昇すると、傾斜面を有する押圧部４２ｂが上側に移動することにより、案内部８３により水平方向に案内された規制部材８１は、図４に示されるように、先端部Ｔの傾斜面が押圧部４２ｂの傾斜面に対してスライドしながら、バネ（付勢部材）Ｓ２の付勢力に抗して退避位置に向かって水平方向に移動する。
The auxiliary portion 42 rises along the guide member G, and the pressing portion 42b of the auxiliary portion 42 protrudes to the regulation position as shown in FIG. 3 before the sitting height at which the bather sits. Of the restriction member 81. When the elevating body 41 and the auxiliary portion 42 are further raised from this state, the pressing portion 42b having the inclined surface moves upward, so that the regulating member 81 guided in the horizontal direction by the guide portion 83 is shown in FIG. As described above, the inclined surface of the tip portion T slides with respect to the inclined surface of the pressing portion 42b, and horizontally moves toward the retracted position against the biasing force of the spring (biasing member) S2.
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、バネＳ２の付勢力により、再度規制位置に戻る。昇降本体４１がさらに上昇すると、図５に示されるように、補助部４２の作動部４２ｃが被作動部材９の被作動部９１の先端部９１ａ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および補助部４２はさらに上昇し、図６に示されるように、補助部４２の作動部４２ｃが被作動部材９の被作動部９１を押し上げ、被作動部９１は回転軸Ａｘ１を中心に回転する。被作動部９１の回転軸Ａｘ１と先端部９１ａとの間の中間部に連動部９２が接続しているので、被作動部９１を押し上げられることにより、被作動部９１に接続された上下方向に延びる連動部９２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、排出弁７が開口Ｏ２を開放する。排出弁７が開口Ｏ２を開放すると、駆動部３１の充填部Ｆの水が、第２排出路６２を介して排出室ＣＨ内に流れ込み、排出室ＣＨから開口Ｏ１を経由して第１排出路６１へと排出される。これにより、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。被作動部９１を押し上げられることにより、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 / lowering body 41 further rises and the pressing portion 42b passes over the regulating member 81 in the vertical direction, the regulating member 81 moved to the retracted position side returns to the regulating position again by the urging force of the spring S2. When the elevating / lowering body 41 further rises, as shown in FIG. 5, the operating portion 42c of the auxiliary portion 42 comes into contact with the tip end portion 91a of the operated portion 91 of the operated member 9. At this point, the elevating body 41 reaches a predetermined height position where the bather can sit, but if the water supply from the faucet 2 is not stopped, the bellows portion 31a of the drive unit 31 tries to further extend. At this time, as the bellows portion 31a extends, the elevating body 41 and the auxiliary portion 42 further rise, and the operating portion 42c of the auxiliary portion 42 pushes up the operated portion 91 of the operated member 9, as shown in FIG. The operated portion 91 rotates about the rotation axis Ax1. Since the interlocking portion 92 is connected to the intermediate portion between the rotation axis Ax1 of the operated portion 91 and the tip end portion 91a, the operated portion 91 is pushed up, so that the interlocked portion 92 is moved in the vertical direction connected to the operated portion 91. The extending interlocking portion 92 is pulled upward against the biasing force of the spring (biasing member) S1, and the discharge valve 7 opens the opening O2. When the discharge valve 7 opens the opening O2, the water in the filling portion F of the drive unit 31 flows into the discharge chamber CH via the second discharge passage 62, and the first discharge passage from the discharge chamber CH via the opening O1. It is discharged to 61. As a result, excessive water is suppressed from being supplied to the drive unit 31, and deformation and damage of the bellows portion 31a of the drive unit 31 and the joint between the drive unit 31 and the supply path 5 or the discharge path 6 are suppressed. can do. By pushing up the actuated portion 91, 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、補助部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８５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と補助部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 sitting height (the position shown in FIG. 5 or the height between FIG. 5 and FIG. 8) to elevate the bather. Preparation for mounting on the main body 41 is completed. When a bather is placed on the elevating body 41, the elevating body 41 normally descends slightly due to the body weight of the bather, but the engaged portion 42a of the auxiliary portion 42 is vertically separated from the regulating member 81. Stop at the position you made. On the other hand, for example, when a hole is formed in the bellows portion 31a, the supply passage 5, the second discharge passage 62, or the like, the discharge valve 7 is damaged, or the connection portion of the supply passage 5 or the discharge passage 6 is disconnected. When the amount of water supplied to the bellows portion 31a is small, or when the discharge valve 7 is opened by operating the operating portion 85 by mistake, the elevating body 41 may descend downward. is there. In the present embodiment, even in such a case, since the regulating member 81 is located at the regulating position, even if the elevating / lowering body 41 descends as shown in FIG. The engaged portion 42a of 42 engages with each other, and the lowering of the elevating / lowering body 41 is limited to a predetermined range. Therefore, the bather can safely get on the elevating body 41, and even if the elevating body 41 descends when the bather gets on the elevating body 41, the elevating body 41 is placed at the position of the regulating member 81. Since the water stays, it is possible to prevent the bather from losing balance and feeling anxious when the elevating body 41 descends.
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８５を操作する。図７に示されるように、操作部８５を操作すると、解除部材８４が操作され、規制部材８１が退避位置に移動し、昇降本体４１が降下するときに、補助部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８５が操作されることにより、回転軸Ａｘ２を中心にカム状の回転部材８４ａが反時計回りに回転し、バネＳ２の付勢力に抗して、板状の移動部材８４ａを退避位置方向に押して、規制部材８１が退避位置に移動する。さらに、操作部８５の操作により、回転部材８４ｂの回転とともに、図５に示される状態から図７に示される状態へと、伝達部８４ｃが反時計回りに回転し、回転した伝達部８４ｃは、被作動部材９の被作動部９１の底部を押すことにより、被作動部９１を回転軸Ａｘ１周りに回転させる。
When the bather rides on the elevating body 41 and the bath preparation is completed, the bather lowers the elevating body 41 so as to be immersed in the hot water in the bathtub Ba. In order to lower the elevating / lowering body 41, a bather or an assistant assisting the bath operates the operation unit 85. As shown in FIG. 7, when the operating portion 85 is operated, the release member 84 is operated, the regulating member 81 is moved to the retracted position, and when the elevating body 41 is lowered, the engaged portion 42a of the auxiliary portion 42 is moved. The restriction member 81 is disengaged from the movement path through which the. In the present embodiment, when the operation portion 85 is operated, the cam-shaped rotating member 84a rotates counterclockwise around the rotation axis Ax2, and resists the biasing force of the spring S2 to move the plate-shaped moving member. By pushing 84a toward the retracted position, the regulating member 81 moves to the retracted position. Further, by operating the operation portion 85, the transmission member 84c rotates counterclockwise from the state shown in FIG. 5 to the state shown in FIG. 7 together with the rotation of the rotating member 84b, and the rotated transmission portion 84c is By pushing the bottom of the operated portion 91 of the operated member 9, the operated portion 91 is rotated around the rotation axis Ax1.
被作動部９１が回転軸Ａｘ１周りに回転すると、図７に示されるように、被作動部９１の回転に連動してロッド状の連動部９２が、バネＳ１の付勢力に抗して排出弁７を上側に移動させ、開口Ｏ２を開放させる。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開口Ｏ２を通過し、排出室ＣＨから開口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８５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 actuated portion 91 rotates about the rotation axis Ax1, as shown in FIG. 7, the rod-shaped interlocking portion 92 interlocks with the rotation of the actuated portion 91 against the biasing force of the spring S1. 7 is moved to the upper side to open the opening O2. As a result, the water in the filling section F of the drive unit 31 passes through the opening O2 opened via the second discharge path 62 and is discharged from the discharge chamber CH by the pressure of the body weight of the bather from the lifting / lowering body 41 side. It is discharged toward the first discharge path 61 via O1, and the elevating body 41 descends. As described above, by operating the operation portion 85, 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 / lowering body 41 can be performed very easily. ..
本実施形態では、回転したカム状の伝達部８４ｃの先端部は、図７に示されるように、被作動部９１の底部に設けられた凹部９１ｂに係合して、被作動部９１は排出弁７が開放した状態の所定の角度で維持される。このため、駆動部３１の充填部Ｆから水を排出する際に、操作部８５を所定の量回転させた後は、操作部８５から手を離したままで水が排出される。
In the present embodiment, as shown in FIG. 7, the tip of the rotated cam-shaped transmission portion 84c engages with the recess 91b provided in the bottom of the operated portion 91, and the operated portion 91 is discharged. The valve 7 is maintained at a predetermined angle in the open state. For this reason, when the water is discharged from the filling section F of the drive unit 31, after rotating the operation section 85 by a predetermined amount, the water is discharged with the hand off the operation section 85.
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と補助部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、解除部材８４の移動部材８４ａが弾性変形可能な板状体により構成されているので、操作部８５が操作されたとしても、移動部材８４ａが弾性変形して撓むことにより、操作部８５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、移動部材８４ａの変形により逃がされる。したがって、操作部８５が強い操作力で操作されても、移動部材８４ａが弾性変形して、操作部８５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。
Note that, 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 its descent is regulated. In addition, if the regulation member 81 moves to the retracted position, the elevating body 41 is lowered before the bather gets on the elevating body 41. In the present embodiment, when the elevating body 41 descends by a predetermined amount, the engaging portion 81a of the regulating member 81 and the engaged portion 42a of the auxiliary portion 42 are restrained from moving the regulating member 81 toward the retracted position. Engage as described. In this case, the restriction member 81 is prevented from moving to the retracted position, so that the restriction member 81 remains at the restriction position and the elevating body 41 can be prevented from falling. Further, in the present embodiment, since the moving member 84a of the releasing member 84 is configured by the elastically deformable plate-shaped body, even if the operating portion 85 is operated, the moving member 84a elastically deforms and bends. As a result, the force of the operation portion 85 to move the restriction member 81 to the retracted position side is released by the deformation of the moving member 84a. Therefore, even if the operating portion 85 is operated with a strong operating force, the moving member 84a is elastically deformed, and the operating force applied to the operating portion 85 is less likely to be transmitted to the regulating member 81. Therefore, the engagement between the engaging portion 81a and the engaged portion 42a is less likely to be released, the movement of the regulating member 81 to the retracted position side is suppressed, and the vertical movement of the elevating body 41 is suppressed.
入浴者の入浴が完了すると、操作部８５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 bathing of the bather is completed, the operating part 85 is operated to close the discharge valve 7, and then the faucet 2 is operated to refill the filling part F of the drive part 31 with water, and the elevating body 41 is moved. The bather is raised and lowered from the elevating body 41. Even at this time, since the regulating member 81 is located at the regulating position, the descending of the elevating body 41 is limited to the predetermined range, and the bather can safely descend from the elevating body 41.
