  Hereinafter, embodiments of the present invention will be described with reference to the drawings. 1 to 3 show a first embodiment of the present invention. FIG. 1 is a front view of the nursing tub 1, FIG. 2 is a left side view of the nursing tub 1, and FIG. 3 is a plan view of the nursing tub 1.

  The entire shape of the nursing tub 1 has a substantially rectangular parallelepiped shape. The nursing tub 1 is disposed on the bathtub 2 and a side surface on the one long side of the bathtub 2 (the rear surface of the bathtub 2) and a pump (not shown). A hot water storage tank 3 for storing hot water to be supplied to the bathtub 2 and connected to the bathtub 2 through a hot water transfer means including a piping member and the like is a main component.

  The bathtub 2 has a substantially rectangular parallelepiped resin or stainless steel container 9 having an opening 4 formed by cutting out the entire area of the side surface of the bathtub 2 in the opposite (front) direction of the hot water storage tank 3. And is supported at a predetermined height. And it moves to the up-down direction between the predetermined upper position and the predetermined lower position via the door moving means 10 (refer FIG. 3) mentioned later, and the right and left facing the front side of the bathtub 3 via the closing means 11 mentioned later A single door member 6 is provided that enables watertight closing between the side wall surface 2a and the lower side wall surface 2a (hereinafter referred to as the peripheral surface of the opening 4).

  The support frame 8 is placed away from the floor surface 5 by four installation legs 26 arranged on the lower surface of the frame 8. The height H1 from the floor surface 5 to the inner bottom surface 2b of the bathtub 2 (container 9) where the care recipient is seated is determined by the care recipient who is seated on a transport device such as a general shower chair (not shown) or a wheelchair for bathing. It is set to a height that allows easy transfer directly to the inner bottom surface 2b, specifically, a height range of 400 mm to 500 mm, preferably 450 mm. The portion of the inner bottom surface 2b where the care recipient is seated is formed in a substantially horizontal shape.

  The left and right inner side surfaces 2d of the bathtub 2 are each provided with a substantially U-shaped handle 7 in front view so that the upper surface portion is located near the upper edge surface 2c and the front surface portion is located near the left and right side wall surfaces 2a. Has been. The handle 7 is to be held by a care recipient when the transfer device is moved from the transport device into the bathtub 2 or from the bathtub 2 to the transport device. In addition, the attachment position of the handle 7 is not limited to the position, and may be provided at any position as long as it is easy for a care recipient to hold.

  As shown in FIG. 1, the door member 6 has a vertically outer dimension and a left and right outer dimension set longer than the inner dimensions of the opening 4 and has a substantially rectangular shape in front view. A seal member 16 made of a soft rubber material is attached in a substantially U shape along the left and right edges and the lower edge of the door member 6 on the side (rear surface side) facing the peripheral surface of the opening 4. Note that the seal member 16 is not on the rear surface side of the door member 6 but on the peripheral surface side of the opening 4 so as to correspond to the left and right edge edges and the lower edge edges on the rear face of the door member 6 moved to a predetermined upper position. You may stick it on.

  Next, a door moving means 10 for moving the door member 6 in the vertical direction between a predetermined upper position and a predetermined lower position, and a closing means 11 for closing the space between the door member 6 and the peripheral surface of the opening 4 in a watertight manner. The configuration will be described. As shown in FIG. 3, the door moving means 10 and the closing means 11 are arranged in the left and right short side directions of the bathtub 2, respectively. Description will be made by paying attention to the configuration of the door moving means 10 and the closing means 11 in the side direction).

  First, the configuration of the door moving means 10 will be described. As shown in FIG. 2, support pillars 12 are erected and fixed over the upper and lower ends of the support frame 8 at positions close to the front surface of the bathtub 2, and a moving member 13 is provided so as to be movable in the vertical direction along the support pillars 12. It has been. As shown in FIG. 3, the moving member 13 is a bent portion 13 a whose one side (door member 6 side) is bent into a substantially U-shape in plan view toward the outer side of the bathtub 2, and the other side is a flat plate. It is set as the surface part 13b.

  The outer peripheral surface of the support column 12 is sandwiched from the front and rear direction by the roller shaft 25 between the flat plate member 17 provided on the opposite side of the flat plate surface portion 13b with respect to the flat plate surface portion 13b and the support column 12, and can be rolled along the support column 12. A four-wheel roller 14 is attached and supported.

  As shown in FIG. 2, the rod portion 15 a whose tip is pivotally mounted at an upper position behind the flat plate surface portion 13 b and the flat plate member 17, the portion 15 a is held so as to be extendable, and the lower portion is the support frame 8. An actuator 15 having a holding portion 15b fixed to the shaft is disposed. The moving member 13 and the actuator 15 described above constitute the door moving means 10 that moves the door member 6 in the vertical direction between a predetermined upper position and a predetermined lower position.

  Therefore, for example, when the rod portion 15a in the contracted state is operated in the extending direction as shown in FIG. 2, the four-wheel roller 14 rolls along the outer peripheral surface of the support column 12, and the moving member 13, that is, the door member. 6 will move upward. The rod portion 15a is electrically controlled such that the extension operation stops when the upper surface 6a of the door member 6 reaches a position (predetermined upper position) where the upper surface 6c of the bathtub 2 is substantially the same height.

  On the contrary, when the rod portion 15a in the extended state is operated in the contracting direction, the door member 6 moves downward. The rod portion 15a stops its contraction operation at a position where the rear lower surface of the flat plate surface portion 13b abuts on a limit switch 27 provided so as to protrude from the lower surface portion of the support frame 8 toward the floor surface 5. At this time, the upper surface 6a of the door member 6 is stopped. The height position (predetermined lower position) is substantially flush with the inner bottom surface 2b of the bathtub.

  As shown in FIG. 2, an upper cam 19 and a lower cam 20 which are bent into a dogleg shape when viewed from the side and have the same shape as each other extend from the flat surface portion 13b and are surrounded by the bent portion 13a. Are arranged so as to face up and down in a U-shaped space 18. One end of each of the upper cam 19 and the lower cam 20 is connected to the door member 6 via a connecting shaft 21 that passes through the bent portion 13a surface that is flush with the flat plate surface portion 13b from the vertical position of the left side of the door member 6. ing.

  The upper cam 19 and the lower cam 20 are respectively pivotally attached to a support shaft 22 inserted over both opposing surfaces of the bent portion 13a at the bent portion, and the other end side is provided to extend in the vertical direction. The upper and lower ends of the elongated cam-shaped cam operation plate 23 are respectively attached by connecting shafts 24. In FIG. 3, 28 is a boss fixed to both the left and right sides of one end of the upper cam 19, and the door member 6 moves in the vertical direction by suppressing unnecessary play in the horizontal direction of the upper cam 19. Sometimes, the door member 6 is prevented from swinging left and right.

  The above-described upper and lower cams 19 and 20 and the cam operation plate 23 press the door member 6 in the direction of the peripheral surface of the opening 4 to press the seal member 16 against the peripheral surface, so that the opening 4 is brought into contact with the door member 6. The closing means 11 for closing watertightly is configured.

  Therefore, for example, when the door member 6 is in the lower position shown in FIG. 2, the closing means 11 does not act, and the seal member 16 is in a non-pressure contact state with the peripheral surface of the opening 4 (see FIG. 3). When the door member 6 at this position is moved upward using the door moving means 10, the upper surface of the cam operation plate 23 contacts the upper surface edge 8 a of the support frame 8 at a certain position.

  Further, when the door member 6 is moved upward, the cam operation plate 23 is pushed downward in the opposite direction to the movement direction of the door member 6 by contact with the upper surface edge portion 8a. As a result, the upper cam 19 and the lower cam 20 are moved. Rotates to the state indicated by the one-dot chain line in FIG. By this rotation, the door member 6 is pressed in the direction of the peripheral surface of the bathtub 2, the seal member 16 is pressed against the peripheral surface, and the opening 4 is water-tightly closed by the door member 6.

  As shown in FIG. 2, the upper cam 19 and the lower cam 20 have the same shape, and the corresponding connecting shaft 24, supporting shaft 22, and connecting shaft 21 are aligned at the same position in the vertical direction. Since the distance between the shafts 22 and the distance between the support shaft 22 and the connecting shaft 21 are the same in the upper cam 19 and the lower cam 20, the upper cam 19 and the upper cam 19 when the door member 6 reaches a predetermined upper position. The distances by which the respective cams move due to the rotation of the lower cam 20 are the same distance, and therefore the pressing forces exerted on the upper part and the lower part of the door member 6 are the same force.

  In addition, although detailed description is abbreviate | omitted, on the upper edge surface 2c of the bathtub 2, in addition to the power switch of the care bathtub 1, the start of the upward movement and the downward movement of the door member 6 is instructed. An operation display unit 29 equipped with various switches such as a door movement switch, a hot water storage switch for instructing the start of hot water storage from the hot water tank 3 to the bathtub 2, and a hot water temperature display unit for displaying the hot water temperature in the bathtub 2 is provided. Is provided.

  Next, the usage method of the care bathtub 1 of 1st embodiment is demonstrated. The door member 6 is moved to a predetermined upper position, and it is assumed that a predetermined amount of hot water is stored in the hot water storage tank 3. The caregiver turns on the power switch and then depresses the door movement switch to move the door member 6 to a predetermined lower position. A care recipient seated on a transport device such as a shower chair is guided to a position near the opening 4.

  A care recipient having a low degree of care required, for example, having a level of care required of 1, transfers from the opening 4 to the inner bottom surface 2b of the bathtub 2 by himself / herself while holding the handle 7 as necessary. In addition, in the case of a care recipient who has a high degree of care required, such as a degree of care required of 3, etc., it may be transferred to the inner bottom surface 2b with the assistance of the caregiver. At this time, since the vicinity of the upper surface 6a of the door member 6 does not protrude upward from the inner bottom surface 2b, it does not hinder the transfer operation of the care recipient and the assistance work of the caregiver. Further, since the height H1 from the floor surface 5 to the inner bottom surface 2b is set to be substantially the same as the seating surface of the transport device, the care recipient is remarkably involved in the transfer from the transport device to the inner bottom surface 2b. Can be transferred easily without labor.

  After confirming that the care recipient has completely entered the bathtub 1, the caregiver presses the door movement switch to move the door member 6 to a predetermined upper position. When the door member 6 reaches a predetermined upper position by the door moving means 10, the closing means 11 automatically operates, so that the caregiver can close the opening 4 in a watertight manner only by an extremely easy operation of pressing the door moving switch. The operation burden on the caregiver's door movement is extremely small.

  The hot water storage switch is pressed, and the hot water in the hot water storage tank 3 is supplied and moved to the bathtub 2. When leaving the bath, the bath water in the bathtub 2 is drained first. After confirming that drainage is complete, the door movement switch is pressed to move the door member 6 to a predetermined lower position. The care recipient needs to transfer to the transport device by himself or with the assistance of the caregiver and complete the bath.

  In the first embodiment described above, the pressing force exerted by the upper cam 19 and the lower cam 20 on the upper part and the lower part of the door member 6 when the door member 6 reaches a predetermined upper position becomes the same force. However, the water pressure exerted on the door member 6 by the hot water supplied into the bathtub 2 becomes lower as the bath member 6 moves upward, so that the pressing force by the upper cam 19 is reduced to the lower cam at the time point. You may make it become low with respect to the pressing force of 20. For example, the pressing force of the upper cam 19 can be reduced by changing the current position of the connecting shaft 21 in the upper cam 19 downward and reducing the distance between the support shaft 22 and the connecting shaft 21. It becomes possible.

  By changing in this way, the repulsive force which the upper part of the door member 6 receives from the seal member 16 when the door member 6 is pressed against the peripheral surface of the opening 4 can be reduced, and the opening 4 can be more suitably opened. It becomes possible to close with the member 6.

  Next, a second embodiment of the present invention will be described with reference to FIGS. 4 is a front view showing the nursing tub 1 of the second embodiment, FIG. 5 is a left side view showing a part of the nursing tub 1, FIG. 6 is a plan view showing the nursing tub 1, and FIG. 3 is a perspective view schematically showing the shape of a door member 31. FIG. 4 to 7, the same or equivalent components as those in FIGS. 1 to 3 are denoted by the same reference numerals, and the description of the components is omitted unless particularly required.

  The nursing bathtub 1 shown in the second embodiment is the first door in which the door member 6 in the first embodiment is formed with a cutout region 30 so that the upper part of the door member 6 has a substantially concave shape in front view. It comprises a member 31 and a second door member 32 having a substantially rectangular shape in front view that can cover the entire region of the cutout region 30 (see FIG. 4), and left and right ends of the lower surface of the second door member 32 Are supported by a horizontal support shaft 33 provided on the first door member 31, and the second door member 32 is rotatable in the forward direction of the bathtub 2 with the horizontal support shaft 33 as a fulcrum (see FIG. 4). The means 11 includes a first closing means 34 for watertightly closing between the first door member 31 and the peripheral surface of the opening 4, a peripheral surface 37 of the cutout region 30 on the front surface of the first door member 31, and the first A second closing means 35 for watertightly closing the rear surface of the second door member 32 ( 5,6 see) is intended to.

  The configuration of the door moving means 10 for moving the door member 6 composed of the first door member 31 and the second door member 32 in the vertical direction and the configuration of the first closing means 34 are the same as those in the first embodiment. Since it is the same, the description is omitted.

  The first door member 31 has a box lid shape as shown in FIG. 7, and a second door member 32 described later is disposed in a space 44 formed by scraping from the front surface to the rear surface direction. On the rear surface side of the first door member 31, a notch whose left and right dimensions are substantially the same as the left and right inner dimensions of the opening 4 and whose vertical dimension is substantially one third of the upper and lower outer dimensions of the first door member 31. Region 30 is formed.

  As shown in FIG. 4, the second door member 32 is a front element and has a substantially rectangular shape, and the upper and lower outer dimensions and the left and right outer dimensions are set to be longer than the respective dimensions of the notch region 30, and the entire area of the notch region 30. It is formed to cover. The peripheral surface of the notch region 30 in the second door member 32 and the first door member 31 on the left and right edges and the lower edge of the second door member 32 on the side facing the notch region 30 (rear surface side). A sealing member 36 that seals water tightly between the two is attached. Note that the seal member 36 is not located at the rear surface side of the second door member 32 but at each edge position of the left and right end edges and the lower end edge of the rear surface of the second door member 32 in a position covering the entire cutout region 30. You may affix on the peripheral surface 37 side of the 1st door member 31 so that it may respond | correspond.

  Horizontal support shafts 33 that protrude horizontally toward the inside of the bathtub 2 are provided at positions slightly above the upper and lower intermediate positions of the left and right inner wall surfaces 45 of the first door member 31 that are orthogonal to the peripheral surface 37, respectively. The left and right end portions of the lower surface of the door member 32 are rotatably supported by a horizontal support shaft 33 (see FIG. 4), and the second door member 32 has the first door member 31 with both horizontal support shafts 33 as fulcrums. Can be rotated in the front direction. In FIG. 4, the second door member 32 shown by a one-dot chain line shows a state in which the door member 32 shown by a solid line is rotated 180 ° downward.

  Next, the 2nd obstruction | occlusion means 35 which obstruct | occludes between the peripheral surface 37 of the notch area | region 30 and the 2nd door member 32 rear surface in the 1st door member 31 is demonstrated. As shown in FIG. 4, the second closing means 35 are symmetrically arranged in the left and right upper direction of the door member 6, but have the same configuration as each other. The description will be made by paying attention to the configuration of the second closing means 35 in the direction).

  In FIG. 6, a locking member 39 is rotatably attached to a pin member 38 that is horizontally protruded and fixed from the upper side of the left side surface of the second door member 32 toward the outer direction in a direction perpendicular to the axial direction of the member 38. Is provided. As shown in FIG. 5, the locking member 39 has a substantially inverted L shape when viewed from the left side, and one part is a grip part 39 a having a length dimension that can be gripped by a caregiver, and the other part is a first part. A hook-shaped locking portion 39b is formed so as to be locked to a locked member 42 formed of a pin member 41 that protrudes and adheres horizontally from the inner wall surface 45 of the door member 31 toward the inside of the bathtub 2.

  The locking member 39 is normally urged counterclockwise in FIG. 5 by a pin member 38 and a torsion spring 40 interposed in the locking member 39. In FIG. 4, 46 is a rotation stopper that prevents the counterclockwise rotation of the locking member 39 by the torsion spring 40. In FIG. 6, the rotation stopper 46 is not shown.

  Accordingly, when the care recipient grasps both the gripping portions 39a and rotates the locking member 39 toward the front surface of the bathtub 2 with the pin member 38 as a fulcrum, the locking of the locking portion 39b with respect to the pin member 41 is released, and the second The rotation of the door member 32 is allowed.
