  Hereinafter, a bathing apparatus according to an embodiment of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a schematic top view showing a configuration of a bathing apparatus 1 according to an embodiment of the present invention. FIG. 2 is a schematic cross-sectional view taken along the line AA in FIG. As shown in FIGS. 1 and 2, the bathing apparatus 1 includes a gantry 10 that is fixedly disposed on a floor F, and a bathtub 11 that is provided on the gantry 10. A bather using the bathing apparatus 1 is immersed in hot water stored in the bathtub 11 while being placed on the stretcher T. FIG.1 and FIG.2 has shown the state in which the stretcher T for mounting a bather was put in the bathtub 11 so that it might be easy to understand the structure of the bathing apparatus 1 of this embodiment. The bather on the stretcher T places his head on the right side in FIGS. 1 and 2 and puts his foot on the left side.

  A column 12 is attached to the gantry 10. The support column 12 penetrates the bottom wall 11a of the bathtub 11 in a liquid-tight manner. The bathtub 11 is provided so as to be movable up and down along the column 12. In addition, raising / lowering of the bathtub 11 is performed by the raising / lowering means 13 provided on the mount frame 10. FIG. Although the structure of the raising / lowering means 13 is not specifically limited, For example, a pantograph mechanism can be utilized. The pantograph mechanism may be driven using, for example, a hydraulic device that operates using a motor. In FIG. 1 and FIG. 2, the bathtub 11 is disposed at a bathing position that is raised higher than the gantry 10.

  The support column 12 is provided with a movable rod 14 provided so that the amount of protrusion from the upper surface of the support column 12 can be changed. Further, in the support column 12, a screw screw 16 that is partially inserted into the hollow movable rod 14 from the lower side and a nut member 17 that is fitted to the screw screw 16 are provided. When the screw 16 is rotated, the nut member 17 moves up and down according to the rotation direction. The lower end of the movable bar 14 is in contact with the upper surface of the nut member 17. For this reason, when the screw screw 16 rotates, the movable rod 14 moves up and down together with the nut member 17 according to the rotation direction.

  In addition, what is necessary is just to utilize the motor etc. which are not illustrated arrange | positioned in the suitable place of the mount frame 10 for the drive of the screw screw 16. FIG. Moreover, the structure etc. which utilize hydraulic_pressure | hydraulic may be sufficient as raising / lowering of the movable rod 14. FIG.

  A shaft 15 is fixed to the tip (upper end) of the movable rod 14. A stretcher base 18 on which the stretcher T is placed is connected to the movable rod 14 via the shaft 15. Specifically, the stretcher base 18 is connected to the movable rod 14 by inserting the shaft 15 into a long hole 18 b of a shaft receiving portion 18 a provided on the lower side of the stretcher base 18. A rail 18c for supporting the stretcher T so as to be movable is provided on the upper surface of the stretcher base 18.

  A support frame 19 is fixed on the upper surface of the column 12. The support frame 19 extends from the support column 12 to one side in the longitudinal direction of the bathtub 11 (the side on which the foot is disposed), and supports one end of the stretcher base 18 so as to be rotatable. Specifically, the stretcher base 18 is rotatable around a shaft 20 supported by the support frame 19. For this reason, when the movable rod 14 moves up and down, the stretcher 18 changes its inclination while rotating around the shaft 20.

  The movable rod 14 and the support frame 19 (an example of the support portion of the present invention) are examples of members that constitute the tilt means (tilt mechanism) of the present invention.

  FIG. 3 is a schematic cross-sectional view showing a state before the stretcher T is arranged on the stretcher base 18 in the bathing apparatus 1 according to the embodiment of the present invention. As shown in FIG. 3, before receiving the stretcher T, the bathtub 11 is normally disposed at a position lower than the above-described bathing position. In addition, before the stretcher T is received, the stretcher base 18 is normally in a horizontal posture in which the rail 18c extends in the horizontal direction. In addition, in the state where the stretcher base 18 is in a horizontal posture, the movable rod 14 protrudes greatly from the upper surface of the support column 12 (see also FIG. 2). In the state shown in FIG. 3, the stretcher base 18 is disposed at a position slightly higher than the side wall of the bathtub 11.

  When bathers are bathed using the bath apparatus 1, first, the stretcher T on which the bather is placed is transported by a stretcher (not shown). The stretcher on which the stretcher T is placed is placed next to the bathtub 11. Then, the stretcher T on the stretcher (where the bather is placed) is transferred to the stretcher base 18. In the present embodiment, a roller R is attached to the lower side of the stretcher T, and the stretcher T is easily transferred to the stretcher base 18 by rolling the roller R on the rail 18c.

  When the stretcher T is placed on the stretcher base 18, the bathtub 11 is raised to a predetermined position by the elevating means 13. At the same time when the bathtub 11 starts to rise or before and after the bathtub 11 starts to rise, the movable rod 14 is lowered and the stretcher T together with the stretcher base 18 is brought into a tilted posture. The reason why the stretcher base 18 is tilted is that the amount of ascent of the bathtub 11 is reduced and the bather on the stretcher T is immersed in the hot water in the bathtub 11. In the present embodiment, the bottom wall 11a of the bathtub 11 is configured to include an inclined surface so that the amount of hot water stored in the bathtub 11 can be reduced.

  By the way, as shown in FIG. 4, when the stretcher base 18 is tilted, one end side (foot side) in the longitudinal direction of the stretcher T placed thereon becomes higher. There is a concern that the tip side of the foot side of T comes out of the water surface. That is, there is a concern that a part of the bather's feet comes out of the hot water in the bathtub 11. Therefore, in the present embodiment, a part of the part on which the foot of the stretcher T is placed is configured to bend (see FIG. 2), and the foot is configured to be firmly attached to the hot water in the bathtub 11.

  However, when the stretcher T is transferred from the stretcher (not shown) to the stretcher base 18, if the leg side of the stretcher T suddenly bends, not only will the bather be uncomfortable, but injury may also occur. Further, it is inconvenient if the assistant has to lift the foot side of the stretcher T when the bather leaves the bathtub 11. In consideration of these points, the bathing apparatus 1 is provided with a stretcher T (on its foot side) in conjunction with the movement of the tilting means (comprising the movable rod 14 and the support frame 19) for tilting the stretcher base 18. Deformation means (deformation mechanism) to be deformed is provided.

  FIG. 5 is a schematic side view showing a state immediately after the stretcher T is transferred onto the stretcher base 18 provided in the bathing apparatus 1 according to the embodiment of the present invention, and is an enlarged view of the periphery of the stretcher base 18. . FIG. 6 is a schematic side view showing a state in which the stretcher 18 is changed from the horizontal posture to the tilt posture after the stretcher T is transferred onto the stretcher 18 provided in the bathing apparatus 1 according to the embodiment of the present invention. It is the figure which expanded and showed the stand 18 periphery.

  In FIGS. 5 and 6, mats and pillows provided on the stretcher T are omitted. The stretcher T is provided with a reclining mechanism, and when the stretcher T is transferred to the stretcher base 18, the upper body of the bather is raised to some extent. For this reason, even if the stretcher 18 is tilted by the tilting means, the bather can keep his head above the water surface. Further, the stretcher T is provided with a shaft S that allows a portion on which a foot is placed to rotate.

  As shown in FIGS. 5 and 6, the support frame 19 that rotatably supports the stretcher base 18 also supports the rotation frame 21 to be rotatable. Specifically, the rotation frame 21 is rotatable about a shaft 22 supported by the support frame 19. One end of the rotating frame 21 is rotatably connected to the stretcher base 18. A shaft 23 is fixed to the other end of the rotating frame 21. A connection bar B connected to the shaft 23 is provided below the stretcher T. The connection bar B is provided so as to be able to slide the shaft 23 and to be rotatable with respect to the shaft 23 while holding the shaft 23. When the stretcher T is transferred to the stretcher base 18, the lower portion of the connection bar B is connected to the shaft 22.

  When the movable rod 14 is lowered (from the state shown in FIGS. 5 to 6), the rotation frame 21 rotates around the shaft 22 in conjunction with the rotation of the stretcher base 18. By this rotation, the side of the rotation frame 21 connected to the stretcher base 18 is lifted, and the side connected to the connection bar B is lowered. For this reason, the stretcher T is deformed by applying a downward force to the portion where the foot is placed. Specifically, in the stretcher T, the portion on which the foot is placed rotates around the shaft S, and the side on which the foot is placed is pulled down.

  On the other hand, when the lowered movable bar 14 is raised (when the state shown in FIGS. 6 to 5 is reached), the leg of the stretcher T is placed on the rotating frame 21 in order to rotate in the opposite direction. The side returns to its original horizontal position. For this reason, it is not necessary for an assistant to lift the leg side of the stretcher T when taking a bath.

  The rotating frame 21 is an example of a rotating part of the present invention, the shaft 23 is an example of a connecting part of the present invention, and these are elements constituting the deformation means of the present invention.

  As can be seen from the above, in the bathing apparatus 1, the bather's body is sufficiently immersed in the hot water in the bathtub 11 while lowering the edge height of the bathtub 11 during bathing (suppressing the rising amount of the bathtub 11). You can make it easy. This is convenient for short assistants. In addition, since the stretcher T is deformed in conjunction with the operation of changing the posture of the stretcher base 18 on which the stretcher T is placed (from horizontal posture to tilt posture, or from tilt posture to horizontal posture), the bather's Comfort and safety can be ensured.

  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, it is preferable that the stretcher base 18 is detachably attached to the movable rod 14 (the support column 12). If comprised in this way, as shown in FIG. 7, the stretcher base 18 can be rotated around the shaft 20 and can be flipped up. The bathing apparatus 1 is a structure which does not need to arrange a complicated and large mechanism in the bathtub 11. For this reason, if the stretcher base 18 can be flipped up, it becomes easy to clean a wide area in the bathtub 11 and is very convenient.

  In the embodiment described above, the posture of the stretcher base 18 can be changed using the movable rod 14 that expands and contracts with respect to the support column 12. The configuration that allows the posture of the stretcher base 18 to be changed is not limited thereto. For example, as illustrated in FIG. 8, a configuration that uses a small cylinder 30 that is rotatably disposed on the support frame 19 may be used. In the example shown in FIG. 8, when the rod 31 of the cylinder 30 is extended (shown in FIG. 8A), the stretcher 18 is in a horizontal posture and the rod 31 of the cylinder 30 is contracted (see FIG. 8). 8 (b)), the stretcher base 18 is tilted.

  Expansion and contraction of the rod 31 of the cylinder 30 is performed by adjusting the amount of liquid (for example, glycerin is preferable) in the cylinder 30. The cylinder 30 is connected to a tank 33 in which a liquid is stored via a pipe 32 passing through the column 12. When the pressing portion 34 included in the tank 33 is pressed and the internal pressure in the tank 33 increases, liquid is injected into the cylinder 30. As a result, the rod 31 extends against the weight of the stretcher base 18. On the other hand, when the pressing portion 34 is not pressed, the rod 31 is contracted by the weight of the stretcher base 18, and the liquid returns to the tank 33. If the pressing portion 34 is pressed when the bathtub 11 is lowered and the pressing portion 34 is not pressed when the bathtub 11 is raised, the posture of the stretcher 18 can be changed in conjunction with the raising and lowering of the bathtub 11. .

  In addition, the configuration of the deformation means (deformation mechanism) described above is merely an example, and the configuration of the deformation means may be changed as appropriate. For example, the connection bar B may remain connected to the shaft 23 when the stretcher T is not on the stretcher base 18.
