Description

  The present invention relates to a bathing apparatus.

  In the past, bathing devices have been developed that allow bathers to immerse themselves in hot water in a bathtub while resting on a stretcher for the purpose of bathing those who need assistance (helpers who need assistance) such as the sick, elderly, and physically disabled. (For example, refer to Patent Document 1).

  In the bathing apparatus disclosed in Patent Document 1, the bather is moved from the stretcher laid on the bathtub to the support in the bathtub along with the stretcher. When the stretcher is moved onto the support base, the door on the side of the bathtub is closed, and an appropriate amount of hot water is stored in the bathtub. Thereafter, the supporter is tilted from the horizontal state, so that the bather can be immersed in hot water up to the shoulder. In addition, a support stand inclines so that a buttock side may become down compared with the bather's foot | side on the stretcher.

JP 2008-278980 A

  By the way, in the bathing apparatus which inclines a support stand at the time of bathing, a stretcher also inclines with a support stand. For this reason, depending on how the bathing apparatus is configured, a situation can occur in which the feet of the bather on the stretcher go out of the hot water by tilting the support base. For example, when the inclination of the support base is increased in order to reduce the depth of the bathtub, the foot tip is likely to go out of the hot water. Moreover, when the bather's height on a stretcher is high, the situation where a foot | tip will go out of hot water may occur. If the feet get out of the hot water, the bather cannot warm up sufficiently, and this situation is not preferable.

  In view of the above points, an object of the present invention is to provide a technique that allows a bather to comfortably bathe in a bathing apparatus that tilts a stretcher on which a bather is placed during bathing.

  In order to achieve the above object, the bathing apparatus of the present invention includes a stretcher including a first frame part and a second frame part rotatably attached to the first frame part, and the first frame part. A support portion that detachably supports the stretcher, an inclination angle changing means that changes an inclination angle of the support portion, and a second frame portion in a predetermined direction relative to the first frame portion. A switching unit that switches between a first state that prevents rotation and a second state that enables rotation in the predetermined direction, and the stretcher is placed on a predetermined position of the support unit In addition, the first state is switched to the second state, and the rotation in the predetermined direction is performed in accordance with the inclination change of the support portion (first configuration).

  In the bathing apparatus having this configuration, when the stretcher is not placed at a predetermined position of the support portion, the second frame portion cannot rotate in a predetermined direction with respect to the first frame portion. On the other hand, when the stretcher is placed at a predetermined position of the support portion, the second frame portion rotates in a predetermined direction with respect to the first frame portion as the inclination of the support portion is changed. That is, in this configuration, the stretcher can be deformed at an appropriate timing. For this reason, according to this structure, it becomes possible to fully immerse a bather's body in the hot water of a bathtub, ensuring the safety of a bather.

  The bathing apparatus having the first configuration further includes a sliding support portion that slidably supports a part of the second frame portion when the second frame portion rotates in the predetermined direction. The configuration (second configuration) is preferable. According to this structure, it can prevent that a 2nd frame part rotates rapidly with the inclination change of a support part, and it is easy to ensure a bather's safety.

  In the bathing apparatus having the first or second configuration, the switching unit is in contact with a part of the second frame portion and prevents rotation in the predetermined direction, and the rotation A moving mechanism that slides the blocking portion, and a position that does not block the rotation of the second frame portion by engaging the moving mechanism when the stretcher is placed at the predetermined position. It is preferable that it is a structure (3rd structure) provided with the engaging part slidably moved. According to this configuration, it is easy to reliably operate the switching unit in conjunction with the movement of the stretcher.

  In the bathing apparatus having the third configuration, the moving mechanism includes a shaft portion attached to the first frame portion and the rotation prevention portion, and is a block portion supported by the shaft portion so as to be slidable. The engaging portion is attached to the support portion, and when the stretcher is brought close to the predetermined position, the part of the block portion is pressed to slide the rotation preventing portion. (4th configuration).

  In the bathing device having the fourth configuration, the moving mechanism further includes a biasing member that biases the block portion in a direction opposite to the pressing direction of the block portion by the engagement portion (fifth configuration). Is preferred. According to this structure, when a stretcher is isolate | separated from a support part, it becomes possible to return a block part to an appropriate position automatically.

  The bathing apparatus having any one of the third to fifth configurations rotates the second frame portion in a direction opposite to the predetermined direction before starting the sliding movement of the rotation preventing portion by the engaging portion. It is preferable that the structure further includes a release mechanism for releasing the contact between a part of the second frame part and the rotation preventing part (sixth structure). According to this configuration, since the rotation blocking unit can be slid in a state where the weight of the second frame unit is not applied to the rotation blocking unit, the sliding movement of the rotation blocking unit can be performed smoothly.

  In the bathing apparatus having any one of the first to sixth configurations, the predetermined direction is preferably a direction in which the second frame portion rotates by its own weight (second configuration).

  In the bathing apparatus having any one of the first to seventh configurations, it is preferable that the second frame portion constitutes a portion on which a bather's foot side placed on the stretcher is placed (eighth configuration). According to this structure, a stretcher can be deform | transformed according to the inclination change of a support part, and it can prevent that a bather's foot tip goes out of hot water.

  The bathing apparatus having any one of the first to eighth configurations further includes a support column that supports the support portion so that the inclination angle can be changed, and a bathtub that moves up and down along the support column (9th configuration). It may be. According to this configuration, after the stretcher is placed on the support part, it is not necessary to perform the work of storing hot water, and the bather can easily take a bath.

  ADVANTAGE OF THE INVENTION According to this invention, the technique which a bather can bathe comfortably can be provided in the bathing apparatus which inclines the stretcher which a bather mounts at the time of bathing and bathes.

<Prior development bathing device>

  1 and 2 are side views schematically showing a bath apparatus 100 developed in advance. In FIG.1 and FIG.2, when the bathing apparatus 100 is seen from the side, the part which cannot be seen originally is drawn so that it may partially see.

  As shown in FIG. 1 and FIG. 2, a bath apparatus 100 developed in advance includes a gantry 1 that is fixedly disposed on a floor F and a bathtub 2 that is disposed on the gantry 1. In addition, the bathing apparatus 100 includes a stretcher not shown in FIGS. 1 and 2. The bather is immersed in the hot water stored in the bathtub 2 while being placed on the stretcher.

  On the gantry 1, a column 11 extending in the vertical direction (vertical direction) is erected. The column 11 penetrates the bottom wall 21 of the bathtub 2 in a liquid-tight manner. The bathtub 2 is provided so as to be movable up and down along the column 11. The bathtub 2 is lifted and lowered by a lifting means (not shown) provided on the gantry 1.

  In addition, although the structure of the raising / lowering means is not specifically limited, The raising / lowering means can employ | adopt the well-known structure using an X link mechanism and a raising / lowering cylinder (for example, hydraulic cylinder), for example. The X link mechanism expands and contracts in the vertical direction by the expansion and contraction of the piston of the lift cylinder, and the bathtub 2 moves up and down by the vertical expansion and contraction of the X link mechanism. FIG. 1 shows a state where the bathtub 2 is lowered to the lowest position, and FIG. 2 shows a state where the bathtub 2 is raised to the highest position.

  A support frame 12 is fixed to the upper surface portion of the column 11. The support frame 12 extends greatly from the support column 11 toward one side of the bathtub 2 in the longitudinal direction (the side where the foot is disposed), and rotatably supports the support base 13 on which the stretcher is placed. The center of the rotation is fixedly arranged on the support frame 12 and connected to one end side of the support base 13 (one end side in the direction parallel to the longitudinal direction of the bathtub 2, the left end side in FIGS. 1 and 2). Shaft 14 bears. The support base 13 changes the inclination angle by rotating around the shaft 14. In other words, the support base 13 is supported by the column 11 so that the inclination angle can be changed.

  The tip end side of the piston 31 of the tilt cylinder 3 constituted by, for example, a hydraulic cylinder is connected to the lower surface side of the support base 13. The main body portion of the tilt cylinder 3 is fixedly disposed in a column 11 provided in a hollow state. The piston 31 of the tilt cylinder 3 penetrates the upper surface of the column 11 in a liquid-tight manner and protrudes from the upper surface of the column 11. The support 13 rotates about the shaft 14 by changing the amount of protrusion of the piston 31 from the upper surface of the column 11 and changes the inclination angle. FIG. 1 shows a state in which the support base 13 is horizontal (inclination angle 0 °). FIG. 2 shows a state in which the support base 13 is tilted from the horizontal.

  In addition, a pair of rails 131 for moving the stretcher is provided on the upper surface of the support base 13. The pair of rails 131 extend in a direction perpendicular to the longitudinal direction of the bathtub 2 (a direction perpendicular to the paper surface in FIGS. 1 and 2).

  Next, a usage example of the bathing apparatus 100 configured as described above will be described with reference to FIGS. 3 to 5 in addition to FIGS. 1 and 2. 3 to 5 are side views schematically shown for explaining an example of use of the bath device 100 developed in advance. When the bather M takes a bath, the state change of the bathing apparatus 100 proceeds in the order of FIG. 3, FIG. 4, and FIG.

  When bathing the bather M using the bathing apparatus 100, as shown in FIG. 1, the bathtub 2 is lowered to the lowest position, and the support base 13 is horizontal. In this state, the rail 131 on the support base 13 is located at a position slightly higher than the upper edge of the bathtub 2. The piston 31 of the tilt cylinder 3 protrudes greatly from the upper surface of the column 11 so that the support base 13 is in a horizontal posture.

  Next, a stretcher (not shown) on which the stretcher 4 is placed is placed on the side surface in the longitudinal direction of the bathtub 2 in the state shown in FIG. 1 (for example, the front side of the paper surface of FIG. 1). A bather M is placed on the stretcher 4. Then, as shown in FIG. 3, the stretcher 4 on the stretcher is transferred from the side surface of the bathtub 2 to the support base 13. Two types of rollers R <b> 1 and R <b> 2 are attached to the lower side of the stretcher 4, and the stretcher 4 is transferred to the support base 13 as the rollers R <b> 1 and R <b> 2 roll along the rail 131.

  The roller R1 contacts the upper surface of the rail 131, and the roller R2 contacts the side surface of the rail 131. In addition, a lock mechanism (not shown) that can fix the stretcher 4 is provided on the support stand 13 so that the stretcher 4 transferred to the support stand 13 does not fall off.

  When the stretcher 4 is placed at a predetermined position of the support base 13, the bathtub 2 is raised to the uppermost position by lifting means (not shown). Thereby, as shown in FIG. 4, the stretcher 4 and the support base 13 are immersed in the hot water in the bathtub 2. At this time, a part of the body of the bather M placed on the stretcher 4 is immersed in hot water, but a part of the upper body, for example, comes out of the hot water. That is, the bather M is not sufficiently immersed in the hot water in the bathtub 2.

  After the bathtub 2 is raised to the uppermost position, the piston 31 of the tilt cylinder 3 is contracted. As a result, the support base 13 on which the stretcher 4 is placed is tilted from the horizontal posture by a predetermined angle (for example, about 20 °) as shown in FIG. When the support base 13 tilts, the stretcher 4 also tilts. At this time, the portion of the stretcher 4 on which the upper body side of the bather M is placed is pushed by the bottom wall of the bathtub 2 and bends. For this reason, by tilting the support stand 13, the bather M can be immersed in the hot water while avoiding the bather M's head from entering the hot water. When bathing, the reverse operation is performed.

  According to the bathing apparatus 100, since the support base 13 can be changed from a horizontal posture to an inclined posture using the tilt cylinder 3, the bather M can be immersed in hot water up to the shoulder while suppressing the rising amount and depth of the bathtub 2. Is possible. For this reason, even an assistant who is short can easily perform assistance work during bathing. Moreover, since it is the structure which does not add a mechanism to the bottom part of the bathtub 2 for the purpose of suppressing the raising amount and depth of the bathtub 2, etc., the bathtub 2 is easy to clean.

By the way, the stretcher 4 in the prior-developed bathing apparatus 100 has a configuration in which the toe side of the stretcher 4 is not bent in consideration of, for example, the safety of the bather M when the stretcher 4 is transferred onto the support base 13. Yes. For this reason, when the support base 13 changes from a horizontal posture to an inclined posture, for example, if the body of the bather M is large, the feet of the bather M may come out of the hot water as shown in FIG. there were. If the toes get out of the hot water, the bather M may not be warmed up sufficiently and may not be able to bathe comfortably. The bathing apparatus according to the embodiment of the present invention is devised to improve such points. Hereinafter, a bathing apparatus according to an embodiment of the present invention will be described.
<Bathing apparatus according to an embodiment of the present invention>

  The bathing apparatus according to the embodiment of the present invention has a structure of a part of a stretcher on which a bather is placed, a support base that supports the stretcher in a separable manner, and a part of the structure in the vicinity thereof. Different. The other part of the bathing apparatus according to the embodiment of the present invention is the same as the bathing apparatus 100 of the prior development. For example, the bathing apparatus according to the embodiment of the present invention includes a bathtub 2 that moves up and down along the column 11. The bathing apparatus according to the embodiment of the present invention includes a tilt cylinder 3 that changes the tilt angle of the support base 13. In addition, the support stand 13 is an example of the support part of this invention. The tilt cylinder 3 is an example of the tilt angle changing means of the present invention.

  Hereinafter, a description will be given focusing on differences from the previously developed bathing apparatus 100. Moreover, the same code | symbol is attached | subjected about the part which overlaps with the bath apparatus 100 developed previously, and the description is abbreviate | omitted when there is no necessity for description in particular.

  FIG. 6 is a schematic side view showing the frame configuration of the stretcher 4 provided in the bathing apparatus according to the embodiment of the present invention. As shown in FIG. 6, the stretcher 4 includes an upper body frame portion UF that is supposed to place the upper body of the bather and a lower body frame portion LF that is supposed to place the lower body of the bather. The lower body frame portion LF includes a first frame portion 40 assumed to be placed from the buttocks of the bather to the knee joint, and a second portion assumed to be placed from the knee joint of the bather to the toes. And a frame portion 41. In other words, the second frame portion 41 constitutes a portion on which the bather's foot side placed on the stretcher 4 is placed. In the present embodiment, each frame portion UF, 40, 41 is covered with a cover member (not shown). However, in some cases, the cover member may not be attached.

  The first frame portion 40 includes two types of rollers R1 and R2 on the lower surface side. These two types of rollers R <b> 1 and R <b> 2 are provided so as to roll along a rail 131 provided on the support base 13. In other words, the rail 131 provided on the support base 13 engages with the first frame portion 40 (specifically, the rollers R1 and R2). The stretcher 4 can be transferred from the outside onto the support portion 13 having the rail 131 due to the presence of the rollers R <b> 1 and R <b> 2 provided in the first frame portion 40. The stretcher 4 can be separated from the support portion 13.

  The upper body frame portion UF is rotatably attached to one end side of the first frame portion 40. The upper body frame unit UF cannot rotate downward (in the direction of rotating by its own weight) from a state where the upper surface thereof is substantially parallel to the upper surface of the first frame unit 40 (the state illustrated in FIG. 6). On the other hand, the upper body frame portion UF can be rotated upward from the state shown in FIG. For this reason, even when the support base 13 is inclined, the bather can be immersed in the hot water to the shoulder opening while avoiding the bather's head on the stretcher 4 from entering the hot water. This is the same as the previously developed bathing apparatus 100 described above.

  The second frame portion 41 is rotatably attached to the first frame portion 40. The attachment position of the second frame portion 41 is an end portion on the opposite side to the side on which the upper body frame portion UF is attached. The second frame portion 41 cannot normally rotate downward (in the direction of rotating by its own weight) from a state (the state shown in FIG. 6) in which the upper surface is substantially parallel to the upper surface of the first frame portion 40. . However, when the stretcher 4 is placed at a predetermined position on the support base 13, it can rotate downward. This is a feature of the bathing apparatus 1 of the present embodiment. Hereinafter, this feature point will be described in detail. The second frame portion 41 can be rotated upward from the state shown in FIG. In this embodiment, the state where the stretcher 4 is placed at a predetermined position of the support base 13 coincides with the center position of the support base 13 in the short direction of the support base 13. State.

  FIG. 7 is an enlarged schematic perspective view showing a part of the stretcher 4 included in the bathing apparatus according to the embodiment of the present invention. Specifically, FIG. 7 is an enlarged schematic view showing a portion surrounded by a broken line in FIG. As shown in FIG. 7, a connecting frame 401 is provided at an end portion of the first frame portion 40 on the side connected to the second frame portion 41.

  FIG. 8 is a schematic perspective view illustrating a configuration of a connection frame 401 included in the first frame unit 40 provided in the bathing apparatus according to the embodiment of the present invention. The connection frame 401 includes a belt-like plate portion 401a and four shaft support portions 401b, 401c, 401d, and 401e protruding from one surface of the plate portion 401a. A rotation shaft 411 provided at one end portion in the longitudinal direction of the second frame portion 41 is rotatably supported by the four shaft support portions 401b to 401e. Thus, the second frame portion 41 is rotatably connected to the first frame portion 40.

  FIG. 9 is an enlarged schematic perspective view showing a state in which the moving mechanism 402 is provided on the connection frame 401 provided in the bathing apparatus according to the embodiment of the present invention. The moving mechanism 402 includes a slide shaft 402a (an example of the shaft portion of the present invention) supported by two shaft support portions 401c and 401d provided near the center of the connection frame 401. The moving mechanism 402 includes a slide block 402b (an example of a block unit according to the present invention) that is slidably supported on the slide shaft 402a. The slide block 402b includes a lever portion 402b1 on the lower surface side. A frame receiving portion 403 is provided on the upper surface side of the slide block 402b.

  Two compression springs 402c (see FIG. 13 described later) are fitted on the slide shaft 402a so as to sandwich the slide block 402b. Due to the action of these two compression springs 402c, the slide block 402b is positioned substantially at the center of the slide shaft 402a when no external force is applied. The compression spring 402c is an example of an urging member of the present invention.

  FIG. 10 is a schematic perspective view of the second frame portion 41 provided in the bathing apparatus according to the embodiment of the present invention when viewed obliquely from below. As shown in FIG. 10, the second frame portion 41 is provided with a protruding portion 412 so as to face the rotation shaft 411. The protruding portion 412 abuts on the frame receiving portion 403 when the slide block 402b is positioned at a substantially central portion of the slide shaft 402a (see FIG. 7). For this reason, the second frame portion 41 normally does not rotate with respect to the first frame portion 40 due to its own weight. That is, normally, the first frame part 40 and the second frame part 41 have the relationship shown in FIG.

  As shown in FIG. 10, a lifting dock 413 is provided on the lower surface side of the second frame portion 41. The lifting dock 413 includes a spherical portion 413a. The operation of the lifting dock 413 will be described later.

  FIG. 11 is a schematic perspective view showing the configuration around the support base 13 provided in the bathing apparatus according to the embodiment of the present invention. As shown in FIG. 11, a protruding piece 132 is provided at one end of the support base 13 in the longitudinal direction. The protruding piece 132 is provided in the central portion of the support base 13 in the short direction (width direction). The protruding piece 132 protrudes in a direction substantially parallel to the longitudinal direction of the bathtub 2. A pressing block 133 is fixed on the protruding piece 132.

  As shown in FIG. 11, the support frame 12 is provided with an extending portion 121 that extends in the same direction as the protruding piece 132. A lifting block 122 is fixed on the distal end portion of the extending portion 121. The lifting block 122 is provided in a substantially truncated pyramid shape. The lifting block 122 is provided with a larger length in the short direction of the bathtub 2 than the pressing block 133. The center position in the short direction of the lifting block 122 and the pressing block 133 coincides with the center position in the short direction of the bathtub 2 when the bathtub 2 is viewed from above. In the present embodiment, the center position of the bathtub 2 in the short direction is the same as the center position of the support base 13 in the short direction.

  FIG. 12 is a schematic side view illustrating the operation of the bathing apparatus according to the embodiment of the present invention when the stretcher 4 is placed on the support base 13. FIG. 13 is a schematic top view for explaining the operation of the bathing apparatus according to the embodiment of the present invention when the stretcher 4 is placed on the support base 13. The stretcher 4 is placed on the support table 13 so that the center position in the short direction coincides with the center position in the short direction of the bathtub 2 (support table 13).

  In addition, when the stretcher 4 is viewed from above, the slide block 402 b, the protruding portion 412, and the lifting dock 413 to which no force is applied from the outside exist on the center line in the short direction of the stretcher 4. Moreover, in FIG. 12, the short direction of the bathtub 2 and the stretcher 4 is a direction orthogonal to a paper surface. In FIG. 13, the short direction of the bathtub 2 and the stretcher 4 is the left-right direction.

  The stretcher 4 is transferred to the support table 13 from, for example, a stretcher or a cleaning table (both not shown). At the start of transfer, the protruding portion 412 of the second frame portion 41 is in contact with the frame receiving portion 403. For this reason, at the start of transfer, the second frame portion 41 does not rotate with respect to the first frame portion 40 due to its own weight. That is, the frame receiving portion 403 constitutes the rotation preventing portion of the present invention.

  When the stretcher 4 is placed on the support base 13, the stretcher 4 is brought close to the support base 13 from the side surface of the bathtub 2, and the rollers R <b> 1 and R <b> 2 provided on the first frame portion 40 and the rail 131 on the support base 13 are engaged. (See FIG. 12A). And as shown to Fig.13 (a), the stretcher 4 is moved along the rail 131 so that the center position of the transversal direction may correspond with the center position of the transversal direction of the bathtub 2. FIG.

  When the movement of the stretcher 4 proceeds to some extent, the lifting dock 413 provided in the second frame portion 41 starts to contact the lifting block 122 attached to the support frame 12. In this state, if the stretcher 4 continues to move in the same direction, the lifting dock 413 is lifted by the lifting block 122, so that the second frame portion 41 moves upward (X2 direction) about the rotation shaft 411. (See FIG. 12B). Thereby, a gap is generated between the protruding portion 412 of the second frame portion 41 and the frame receiving portion 403. Since the weight of the second frame portion 41 is not applied to the frame receiving portion 403, the slide movement of the slide block 402b is facilitated.

  When the movement of the stretcher 4 in the same direction is further continued, as shown in FIG. 13B, the lever portion 402b1 provided on the lower side of the slide block 402b and the pressing block 133 start to contact each other. When the movement of the stretcher 4 in the same direction is further continued, the pressing block 133 presses the lever portion 402b1, and the slide block 402b slides along the slide shaft 402a. When the stretcher 4 is moved until the center position in the short direction of the stretcher 4 substantially coincides with the center position in the short direction of the bathtub 2 (the stretcher 4 is moved to a predetermined position of the support base 13), The frame receiving part 403 reaches a position where it does not contact the protruding part 412 (see FIG. 13C). The pressing block 133 constitutes the engaging portion of the present invention.

  In the state shown in FIG. 13C, the second frame portion 41 is not disturbed by the frame receiving portion 403 from rotating downward (in the direction rotating by its own weight) with respect to the first frame portion 40. That is, the second frame portion 41 can be rotated downward with respect to the first frame portion 40. However, since the lifting dock 413 is supported by the lifting block 122, the second frame portion 41 does not immediately rotate downward even when the state shown in FIG.

  With the stretcher 4 moved to a predetermined position of the support base 13 (a position where the center position in the short direction of the stretcher 4 and the center position in the short direction of the bathtub 2 substantially coincide), the support base 13 is horizontally The state is tilted. As shown in FIG. 12C, the second frame portion 41 rotates downward (X1 direction) with respect to the first frame portion 40 as the inclination of the support base 13 is changed. At this time, the lifting dock 413 slides on the lifting block 122. That is, the lifting block 122 constitutes the sliding support portion of the present invention. Due to the presence of the lifting block 122, the second frame portion 41 can be prevented from suddenly rotating downward, and the safety of the bather on the stretcher 4 can be ensured.

  FIG. 14 is a schematic diagram illustrating a state where the bather M is immersed in the hot water of the bathtub 2 using the bathing apparatus according to the embodiment of the present invention. As described above, in the bathing apparatus of the present embodiment, when the support base 13 is tilted, the second frame portion 41 of the stretcher 4 on the support base 13 rotates downward. For this reason, as shown in FIG. 14, it is possible to suppress a situation in which the feet of the bather M placed on the second frame portion 41 get out of the hot water in the bathtub 2. That is, the bather M can bathe comfortably by warming the whole body by immersing it in hot water.

  When the bather M gets out of the hot water, the support base 13 is returned from the inclined posture to the horizontal posture. At this time, since the lifting dock 413 is pressed by the lifting block 122, the second frame portion 41 also returns to the horizontal state. Further, when the support 4 is moved along the rail 131 in order to pull out the stretcher 4 from the bathtub 2, the slide block 402b returns to the center of the slide shaft 402a by the action of the compression spring 402c. For this reason, even if the contact between the lifting dock 413 and the lifting block 122 is released, the second frame portion 41 rotates due to its own weight because the protruding portion 412 and the frame receiving portion 403 contact each other. Can be prevented. That is, separation of the stretcher 4 from the support base 13 (for example, transfer to a stretcher or the like) is completed while the horizontal state of the second frame portion 41 is maintained.

  As can be seen from the above, the frame receiving portion 403, the moving mechanism 402, and the pressing block 133 of the present embodiment rotate the second frame portion 41 in a predetermined direction (downward) with respect to the first frame portion 40. It functions as a switching means for switching between the first state to be blocked and the second state that enables the rotation in the predetermined direction. That is, the frame receiving portion 403, the moving mechanism 402, and the pressing block 133 constitute the switching means of the present invention.

Further, the lifting block 122 and the lifting dock 413 rotate the second frame portion 41 upward (in a direction opposite to the predetermined direction) before starting the pressing by the pressing block 133, so that the protruding portion 412 (second A release mechanism for releasing the contact between a part of the frame portion 41 and the frame receiving portion 403 is configured. That is, the lifting block 122 and the lifting dock 413 constitute a release mechanism of the present invention.
<Others>

  The embodiment described above is merely an example of the present invention. The configuration of the embodiment described above may be changed as appropriate without departing from the technical idea of the present invention.

  For example, in the above, a hydraulic cylinder is used as the tilt angle changing means, but this is only an example. The inclination angle changing means may be configured using, for example, a screw screw driven by a motor.

  In the above, the release mechanism that releases the contact between the projecting portion 412 and the frame receiving portion 403 by rotating the second frame portion 41 upward before the pressing of the lever portion 402b1 by the pressing block 133 is started. Provided. However, this is only an example, and the release mechanism may not be provided in some cases. It is preferable to provide a release mechanism because the slide block 402b can be smoothly moved with respect to the slide shaft 402a.

  In the above description, the lifting block 122 is provided on the support base 13. However, this is only an example. The lifting block may be obtained, for example, by forming a convex portion on the bottom surface (inclined surface) of the bathtub 2. At this time, for example, a roller 414 provided on the lower surface of the second frame portion 41 may be used instead of the lifting dock.

  Moreover, although the case where this invention was applied to the bathing apparatus of the type which the bathtub 2 raises / lowers was shown above, the application range of this invention is not limited to this. That is, the present invention can be widely applied to bathing apparatuses having a function of tilting (inclining) a support base regardless of whether or not the bathtub is raised or lowered.
