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 device disclosed in Patent Document 1, the bather is moved from the stretcher laid on the bathtub to the stretcher in the bathtub together with the stretcher. When the stretcher is moved onto the stretcher base, the door on the side of the bathtub is closed, and an appropriate amount of hot water is stored in the bathtub. After that, the stretcher is tilted from the horizontal state, so that the bather can be immersed in hot water up to the shoulder. In addition, a stretcher base inclines so that a buttocks side may become down compared with the foot side of the bather who rested on the stretcher.

JP 2008-278980 A

  By the way, in the bathing apparatus which inclines a stretcher base and bathes, a stretcher tilts with a stretcher base. For this reason, depending on how the bathing apparatus is configured, a situation may occur in which the feet of the bather placed on the stretcher go out of the hot water by tilting the stretcher base. If the feet get out of the hot water, the bather cannot be warmed up sufficiently, which 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 bathe comfortably in a bathing apparatus that bathes a bather placed on the stretcher by tilting the stretcher base.

  In order to achieve the above object, a 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 a bather on the stretcher. A bath for storing hot water in which water is immersed, a stretcher provided so that the first frame portion can be fixed, and a tilting means for changing the tilt angle of the stretcher, and a drive for the tilting means And a restricting means for restricting rotation of the second frame portion with respect to the first frame portion in a predetermined direction (first configuration).

  According to this configuration, the second frame portion is changed to the first frame portion by changing the inclination angle of the stretcher base (the first frame portion is fixed) on which the stretcher is mounted using the tilt means. The stretcher can be deformed by rotating (relatively rotating). Since the second frame portion is provided with a restricting means for restricting the direction of rotation of the second frame portion with respect to the first frame portion when the tilt means is driven, the second frame portion rotates in a direction opposite to the planned direction. It is possible to avoid inconvenience in the deformation of the stretcher by moving. That is, according to this structure, a bather can be bathed comfortably.

  In the bathing apparatus having the first configuration, the restricting unit may be configured to rotate the second frame unit relative to the first frame unit when the tilting unit moves the stretcher in a direction in which an inclination angle increases. It is preferable that the configuration (second configuration) includes first regulating means for regulating movement in the first direction. According to this configuration, it is possible to prevent inconveniences when the tilting means increases the tilt of the stretcher.

  In the bathing apparatus having the second configuration, the first direction is a direction opposite to a direction in which the second frame portion is about to rotate with respect to the first frame portion by buoyancy received from the hot water of the bathtub. A configuration (third configuration) is preferable. According to this configuration, it is possible to avoid occurrence of a situation in which the second frame portion does not perform planned deformation due to buoyancy.

  In the bathing apparatus having any one of the first to third configurations, the restricting means may include the second frame portion of the second frame portion when the tilting means moves the stretcher in a direction in which an inclination angle is reduced. It is preferable that the configuration (fourth configuration) includes a second restricting unit that restricts rotation of the first frame portion in the second direction. According to this configuration, it is possible to prevent inconvenience when the tilt of the stretcher is reduced by the tilting means. Note that the second direction is opposite to the first direction described above.

  In the bathing apparatus having any one of the first to fourth configurations, the regulating means uses a member provided on the stretcher and a member provided on a support portion that rotatably supports the stretcher base. It may be configured (fifth configuration). According to this configuration, the restricting means can be realized easily and at low cost.

  In the bathing apparatus having any one of the first to fifth configurations, it is preferable that the second frame portion constitutes a portion on which a bather's feet are placed (sixth configuration). In this configuration, since the stretcher can be appropriately deformed in accordance with the tilt change of the stretcher base by the tilt means, it is possible to prevent the problem that the foot tip comes out of the hot water when the bather is immersed in the hot water. it can. In addition, it is preferable that the first frame portion constitutes a portion that is placed on the upper side of the body with respect to a portion that is placed on the second frame portion, and the second frame portion of the first frame portion is attached. A third frame portion (for example, a backrest portion) may be rotatably attached to the opposite side of the first frame portion.

  In the bathing apparatus according to any one of the first to sixth configurations, the bathtub is provided so as to be movable up and down, and the stretcher can be switched between a state of entering the bathtub and a state of exiting the bathtub. (Seventh configuration). According to this configuration, after the stretcher (where the bather is placed) is placed on the stretcher stand, it is not necessary to perform the work of storing hot water, and the bather can easily bathe comfortably.

  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 a stretcher stand and bathes the bather who mounted on the stretcher.

Hereinafter, a bathing apparatus according to an embodiment of the present invention will be described in detail with reference to the drawings. However, in order to facilitate understanding of the present invention, the bathing apparatus developed by the applicant in advance and the problems thereof are described first, and then the bathing apparatus according to the embodiment of the present invention is described. enter.
<Prior development bathing device>

  1 and 2 are side views schematically showing a bath apparatus 100 developed in advance. FIG. 1 is a diagram showing a standby state before a bather is bathed. FIG. 2 is a diagram illustrating a state where a bather is bathed. 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 a raising / lowering means is not specifically limited, In the bathing apparatus 100, the raising / lowering means is comprised using the X link mechanism and the raising / lowering cylinder (for example, hydraulic cylinder). 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 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 (an example of a support portion of the present invention) is fixed to the upper surface portion of the support 11. The support frame 12 extends greatly from the column 11 toward one side in the longitudinal direction of the bathtub 2 (the side on which the foot is disposed), and rotatably supports the stretcher base 13 on which the stretcher is placed. The center of the rotation is fixedly disposed on the support frame 12 and connected to one end side of the stretcher 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 stretcher 13 changes the inclination angle by rotating around the shaft 14.

  The front end side of the piston 31 of the tilt cylinder 3 (an example of the tilting means of the present invention) configured by, for example, a hydraulic cylinder is connected to the lower surface side of the stretcher 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. Due to the variation of the protrusion amount of the piston 31 from the upper surface of the support column 11, the stretcher base 13 rotates around the shaft 14 and changes its inclination angle. FIG. 1 shows a state in which the stretcher base 13 is horizontal (inclination angle 0 °). FIG. 2 shows a state in which the stretcher base 13 is inclined by a predetermined angle from the horizontal.

  In addition, a rail 131 is provided on the upper surface of the stretcher base 13 to support the stretcher so as to be movable. The rail 131 extends 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, the operation of the bathing apparatus 100 when the bather takes a bath using 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. To do. FIGS. 3 to 5 are schematic side views for explaining the operation of the bath device 100 of the prior development. FIG. 3 is a view in which a stretcher 4 on which a bather M is placed is added to FIG. 1. FIG. 5 is a diagram in which a stretcher 4 on which a bather M is placed is added to FIG. 2. 4 is a diagram showing a state in the middle of the transition from the state of FIG. 3 to the state of FIG.

  When the bather M bathes using the bath apparatus 100, as shown in FIG. 1, the bathtub 2 is lowered | hung to the lowest position and the stretcher base 13 is made horizontal. In this state, the stretcher base 13 is located at a position slightly higher than the upper edge of the bathtub 2 (out of the bathtub). Further, in a state where the stretcher base 13 is in a horizontal posture, the piston 31 of the tilt cylinder 3 protrudes greatly from the upper surface of the column 11.

  Next, a stretcher (not shown) on which the stretcher 4 (the bather M is placed) is placed on the side surface (side surface in the longitudinal direction) of the bathtub 2 in the state shown in FIG. Then, as shown in FIG. 3, the stretcher 4 on the stretcher is transferred from the side surface of the bathtub 2 to the stretcher base 13. Rollers R 1 and R 2 are attached to the lower side of the stretcher 4, and the stretcher 4 is transferred to the stretcher base 13 when the rollers R 1 and R 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. Further, the stretcher 4 is fixed to the stretcher base 13 by a lock mechanism (not shown) so that the stretcher 4 moved to the stretcher base 13 does not fall off.

  When the stretcher 4 is placed at a predetermined position of the stretcher base 13, the bathtub 2 is raised to the uppermost position by lifting means (not shown). Thereby, as shown in FIG. 4, the stretcher base 13 on which the stretcher 4 is placed enters the bathtub from the outside of the bathtub. At this time, the stretcher 4 also enters the bathtub, but the bather M placed on the stretcher 4 is only partially immersed in the hot water, and a large part of the upper body comes out of the hot water. That is, the bather M cannot obtain a sufficient bathing state.

  When the bathtub 2 is moved up to the uppermost position, the piston 31 of the tilt cylinder 3 is then contracted, and the stretcher base 13 on which the stretcher 4 is placed, as shown in FIG. Tilted to about °). When the stretcher 13 is tilted, the stretcher 4 is also tilted. 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 stretcher base 13, the bather M can be immersed in the hot water while avoiding the bather M's head from entering the hot water.

  According to the bathing apparatus 100, since the stretcher 13 can be changed from the horizontal posture to the tilted posture using the tilt cylinder 3, the bather M can be immersed in the hot water to the shoulder while suppressing the amount of raising the bathtub 2. Is possible. For this reason, even an assistant who is short can easily perform assistance work during bathing. When bathing, the reverse operation is performed.

By the way, the stretcher 4 in the previously developed bathing apparatus 100 is configured such that the foot side of the stretcher 4 is not bent in consideration of the safety of the bather M and the like. For this reason, when the stretcher base 13 is changed from the horizontal posture to the inclined posture, as shown in FIG. 5, the feet of the bather M may get out of the hot water. When the toes get out of the hot water, the bather M cannot be warmed up sufficiently and cannot take a comfortable bath. The bathing apparatus according to the embodiment of the present invention is devised to improve such points. Hereinafter, the bathing apparatus which concerns on embodiment (this embodiment) of this invention is demonstrated.
<Bathing apparatus of this embodiment>

  The bathing apparatus of this embodiment is different from the bathing apparatus 100 of the prior development only in the structure of a part of the stretcher on which the bather is placed and the structure of the stretcher base on which the stretcher is placed and a part of the periphery thereof. For this reason, it demonstrates focusing on a different part from the bathing apparatus 100 of prior development. 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 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. The stretcher 4 includes a base frame portion 41 and a leg frame portion 42 provided to be rotatable with respect to the base frame portion 41. The base frame portion 41 is an example of the first frame portion of the present invention, and the leg frame portion 42 is an example of the second frame portion of the present invention. Further, a cover member (not shown) is appropriately attached to the base frame portion 41 and the leg frame portion 42.

  The base frame portion 41 includes two types of rollers R <b> 1 and R <b> 2 that engage with a rail 131 provided on the stretcher base 13, and is provided so as to be fixed to the stretcher base 13. A backrest frame portion 43 (see FIG. 9 described later) is rotatably attached to the base frame portion 41 on the side opposite to the side on which the leg frame portion 42 is attached.

  The leg frame portion 42 mainly constitutes a portion on which the bather M's feet are placed. The leg frame portion 42 includes a leg rotation support shaft 421 that is rotatably supported by the base frame portion 41. That is, the leg frame part 42 is rotatable with respect to the base frame part 41 about the leg part rotation support shaft 421. In order to exhibit the function as the stretcher 4, the leg frame part 42 is normally desired to extend almost straight from the base frame part 41 as shown in FIG. 6. Therefore, the lock means 50 is provided so that the leg frame portion 42 does not rotate downward (X1 direction in FIG. 6) due to the action of gravity.

  The leg frame portion 42 can be slightly rotated in the direction of the arrow X2 in FIG. 6 (the direction in which the leg frame portion 42 is lifted). However, the amount of rotation is limited by the collision with the base frame portion 41. ing.

  As shown in FIG. 6, the lock means 50 includes a first lock piece 51 fixed to one end portion of the unlocking rotation support shaft 411 rotatably supported by the base frame portion 41, and a leg portion rotation. And a second lock piece 52 fixed to one end of the movable support shaft 421 (the end on the same side as the first lock piece 51 is provided). When the leg frame portion 42 extends substantially straight with respect to the base frame portion 42 (the state shown in FIG. 6 corresponds), one side of the first lock piece 51 and one side of the second lock piece 52 And abut. For this reason, even if the leg frame portion 42 tries to rotate due to the action of gravity, the rotation of the second lock piece 52 is obstructed by the first lock piece 51. Therefore, in the state shown in FIG. 6, the leg frame portion 42 does not rotate downward (X1 direction) due to the action of gravity.

  In addition, although the 1st lock piece 51 is provided in the one end part of the rotation support shaft 411 for lock release, depending on the case, you may provide in the both ends. Moreover, although the 2nd lock piece 52 is provided in the one end part of the leg part rotation support shaft 421, you may be provided in both ends depending on the case.

  As shown in FIGS. 6 and 7, the bathing apparatus of the present embodiment includes an unlocking means 60 that releases the lock by the locking means 50 when the stretcher 4 is placed on the stretcher base 13. The lock release means 60 is provided not only on the stretcher 4 but also on the stretcher base 13 and the support base 12 that supports the stretcher base 13. FIG. 7 is a schematic perspective view showing the peripheral configuration of the stretcher base 13 provided in the bathing apparatus according to the embodiment of the present invention.

  As shown in FIG. 6, the unlocking means 60 includes a lifting dock 61 provided at a substantially central portion in the width direction of the leg frame portion 42 provided in a substantially rectangular shape. The lifting dock 61 protrudes from the lower surface of the leg frame portion 42. The lifting dock 61 is provided in a substantially trapezoidal frame shape in a side view, and a pair of tongue portions 612 projecting obliquely upward are provided on both side surface portions of the lower end portion 611.

  Further, as shown in FIG. 6, the unlocking means 60 includes an unlocking lever 62 provided at a substantially central portion in the width direction of the unlocking rotation support shaft 411. The lock release lever 62 protrudes obliquely downward (in the direction toward the base frame portion 41) from the lock release rotation support shaft 411. The lock release lever 62 is provided in the shape of a round bar, and its tip is rounded.

  Further, as shown in FIG. 7, the lock releasing means 60 includes a lifting block 63 provided on a protruding piece 121 protruding from one end of the support portion 12 in the longitudinal direction. The lifting block 63 is provided in a substantially truncated pyramid shape.

  Further, as shown in FIG. 7, the lock release means 60 includes a lock release block 64 provided on a protruding piece 132 protruding from one end of the stretcher base 13 in the longitudinal direction. The unlocking block 64 is provided in a substantially trapezoidal column shape.

  As an example, both the lifting block 63 and the unlocking block 64 are arranged at the center in the width direction of the bathtub 2 (the arrow Y direction in FIG. 7 and the direction perpendicular to the paper surface in FIG. 1). However, the lifting block 63 has a larger length in the width direction of the bathtub 2 than the unlocking block 64.

  FIG. 8 is a schematic side view for explaining the operation of the unlocking means 60 provided in the bathing apparatus according to the embodiment of the present invention. The operation of the unlocking means 60 will be described with reference to FIG. In FIG. 8A, the first lock piece 51 and the second lock piece 52 come into contact with each other, and the second frame portion 42 does not rotate with respect to the first frame portion 41 by the lock means 50. It is in a locked state. For example, when the stretcher 4 is placed on the stretcher, the lock means 50 is in the state shown in FIG.

  When the stretcher 4 on the stretcher is transferred from the side surface of the bathtub 2 to the stretcher 13, the tongue 612 of the lifting dock 61 hits the lifting block 63 during the transfer. When the transfer of the stretcher 4 is continued in the state where both hit, the leg frame 42 rotates in the direction in which the leg frame 42 is lifted (X2 direction in FIG. 6), and the lifting dock 61 rides on the lifting block 63. (See FIG. 8B).

  When the lower end portion 611 (see FIG. 6) of the lifting dock 61 is placed on the upper surface of the lifting block 63 and the leg frame portion 42 is lifted, there is a gap between the first lock piece 51 and the second lock piece 52. (See FIG. 8B). Thereby, the 1st lock piece 51 becomes rotatable. If the transfer of the stretcher 4 is further continued in this state, the lock release lever 62 then hits the lock release block 64. When the transfer is further continued in this state, the lock release lever 62 is pushed up by the lock release block 64. As a result, the first lock piece 51 rotates (rotates in the X1 direction in FIG. 6) together with the unlocking rotation support shaft 411 (see FIG. 6), and the rotation of the second lock piece 52 is the first. The state blocked by the lock piece 52 is eliminated (see FIG. 8C). That is, the lock by the lock means 50 is released.

  When the transfer of the stretcher 4 to the stretcher base 13 is completed, the lock unit 50 and the lock release unit 60 are in the state shown in FIG. In the state shown in FIG. 8C, the lifting dock 61 is placed on the lifting block 63. For this reason, even if the lock by the locking means 50 is released, the leg frame portion 42 does not immediately rotate relative to the base frame portion 41.

  When the stretcher 13 is changed from the horizontal posture to the inclined posture using the tilt cylinder 3 in the state shown in FIG. 8C (that is, the state where the transfer of the stretcher 4 to the stretcher 13 is completed), the lock means 50 Since the lock is released, the leg frame portion 42 rotates relative to the base frame portion 41. Specifically, only the base frame portion 41 of the base frame portion 41 and the leg frame portion 42 moves together with the stretcher base 13. And the leg frame part 42 will be in the state which turned relative to the base frame part 41 by the effect | action of gravity, and was bent (refer FIG.8 (d)). In this embodiment, the leg frame part 42 is supported by the lifting block 63 even in this state.

  As a result, as shown in FIG. 9, in the present embodiment, it is possible to suppress a situation in which the feet of the bather M placed on the leg frame portion 42 get out of the hot water in the bathtub 2. When the stretcher 13 is returned from the inclined posture to the horizontal posture and the stretcher 4 is transferred from the stretcher 13 to the stretcher, the lock means 50 and the lock release means 60 perform the reverse operation. In addition, FIG. 9 is the side view which showed typically the bathing state of the bather M in the bathing apparatus which concerns on embodiment of this invention.

  By the way, when the stretcher base 13 is inclined from the horizontal state, there may occur a situation in which the leg frame portion 42 is not properly bent downward due to the buoyancy received from the hot water stored in the bathtub 2. If the leg frame 42 is not properly bent downward, the bather M's feet may get out of the hot water. For example, when a cover formed by blow molding or the like is attached to the leg frame portion 42, it becomes easy to be influenced by buoyancy.

  Therefore, in the present embodiment, as shown in FIG. 10, when the stretcher base 13 is inclined from the horizontal state, the first frame that restricts the rotation of the leg frame portion 42 relative to the base frame portion 41 in the first direction. A regulating means 70 is provided. The first direction is a counterclockwise direction in FIG. 10, and is the opposite direction to the direction in which the leg frame portion 42 rotates with respect to the base frame portion 41 due to the buoyancy received from the hot water in the bathtub 2.

  In addition, FIG. 10 is a schematic side view for demonstrating the control means with which the bathing apparatus which concerns on embodiment of this invention is provided. FIG. 10 shows a state where the transfer of the stretcher 4 to the stretcher base 13 is completed (the same state as FIG. 8C). In the state shown in FIG. 10, the stretcher base 13 is horizontal (inclination angle 0 °).

  The lifting dock 61 and the lifting block 63 in FIG. 10 are slightly different in shape from those described above, but their operation is generally the same, so detailed description thereof is omitted. However, in the configuration shown in FIG. 10, a depression is provided in the upper portion of the lifting block 63. Due to this influence, the leg frame portion 42 extends straight from the base frame portion 41 in a substantially horizontal direction in a state where the stretcher 4 is arranged at a predetermined position (when the transfer of the stretcher 4 to the stretcher base 13 is completed). It has been put out.

  As shown in FIG. 10, the first restricting means 70 includes a round bar 71 fixed to the lifting dock 61 of the stretcher 4. The rod-like member 71 extends in a direction perpendicular to the paper surface in FIG. Moreover, the 1st control means 70 contains the bending member 72 obtained by bending a plate-shaped member. The bending member 72 is fixed to the support portion 12 that supports the stretcher base 13 (more specifically, the portion extending from the support portion 12).

  FIG. 11 is a schematic plan view of the rod-like member 71 and the bending member 72 constituting the first restricting means 70 as seen from above. As shown in FIG.10 and FIG.11, the bending member 72 is arrange | positioned so that the rod-shaped member 71 may be covered by the inclination part 72a. As shown in FIG. 11, the bent portion 72 is provided with a notch 72 b, in order to prevent the lifting dock 61 from colliding with the bending member 72.

  FIG. 12: is a schematic side view for demonstrating the effect | action of the control means with which the bathing apparatus which concerns on embodiment of this invention is provided. Fig.12 (a) is a figure which shows the state in which the stretcher base 13 was inclined about 10 degrees from the state shown in FIG. FIG.12 (b) is a figure which shows the state in which the stretcher base 13 incline about 20 degrees from the state shown in FIG.

  When the stretcher 13 in the horizontal state starts to tilt, the rod-like member 71 comes into contact with the bending member 72 as shown in FIG. For this reason, when the inclination angle of the stretcher base 13 is increased, even if buoyancy is applied to the leg frame part 42, the rotation of the leg frame part 42 with respect to the base frame part 41 is bent downward (FIG. 12). In the counterclockwise direction). Accordingly, as shown in FIG. 12B, when the inclination of the stretcher base 13 is increased, the leg frame part 42 is sufficiently bent with respect to the base frame part 41, and the foot of the bather M is It can prevent getting out of hot water.

  When the stretcher 13 is returned from the inclined state shown in FIG. 12B to the horizontal state shown in FIG. 10, the base frame of the leg frame part 42 is used because the lifting dock 61 abuts on the lifting block 63. The rotation with respect to the portion 41 is restricted in the upward direction (clockwise direction in FIG. 12). Therefore, when the inclination angle of the stretcher base 13 is reduced, the leg frame portion 41 returns to a state of extending almost straight with respect to the base frame portion 41.

The upward direction described above is opposite to the restriction direction by the first restriction means 70, and corresponds to the second direction of the present invention. That is, the lifting dock 61 and the lifting block 63 regulate the rotation of the leg frame portion 42 with respect to the base frame portion 41 in the second direction when the stretcher base 13 is moved in a direction in which the inclination angle decreases. 2 It can be said that it is the regulation means 80.
<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, when the stretcher base 13 is moved in the direction in which the inclination angle increases, the first restriction means for restricting the rotation of the leg frame part 42 with respect to the base frame part 41 in the first direction (counterclockwise direction in FIG. 10). May be configured to use a tension spring 90 as shown in FIG.

  In FIG. 13, one end of the tension spring 90 is attached to a part of the leg frame portion 42, and the other end is attached to the unlocking rotation support shaft 411 supported by the base frame portion 41. The tension spring 90 restricts the direction in which the leg frame 42 rotates when the stretcher 13 is changed from the horizontal posture to the inclined posture by the biasing force in the X1 direction (first direction) in FIG. To do. Note that the number and attachment positions of the tension springs 70 may be changed as appropriate.

  In the above, a hydraulic cylinder is used as the tilting means, but this is only an example. The tilting unit may be configured using, for example, a screw screw driven by a motor.

  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. In other words, the present invention is widely applicable to bathing apparatuses having a function of tilting (tilting) the stretcher base regardless of the presence or absence of the bathtub lifting function.
