  However, in the conventional bathing apparatus, since the bathtub and the stretcher move up and down by the same distance, it is easy to feel that the stretcher is moving, and it is easy to give anxiety to the bather.

  The present invention has been made in view of such circumstances, and it is an object of the present invention to provide a bathing apparatus that is less susceptible to the sense that the bather is moving up and down and is less likely to feel anxiety due to the lifting.

The bathing apparatus according to claim 1 includes a movable tub that is a bathtub in which a bather is immersed in hot water, a base that holds the movable tub from below, a movable tub lifting and lowering means that lifts and lowers the movable tub from the base, and a base. Standing up, pivoting the bottom of the movable tank in a watertight and slidable manner, the first link and the second link pivoted in an X shape, placed inside the bottom of the movable tank, and fixed the stretcher And a cross link having a stretcher cradle on the upper side, the lower end of the first link of the cross link being fixed to the bottom of the movable tank so as to be rotatable, and the lower end of the second link being slidable. Connected to the bottom, the upper end of the first link is slidably connected to the stretcher cradle, the upper end of the second link is pivotally fixed to the stretcher cradle, and the column is connected to the upper end of the column. A sliding wheel having a rotating shaft extending substantially horizontally from the side toward the outer side, wherein the first link is The slide ring provided along the length direction of the link has a slide groove with which the slide ring comes into sliding contact, and the first link is regulated by the slide wheel via the slide groove and is moved along the slide wheel. A strut that is connected to a sliding wheel so as to be slidable in the length direction of the link and that does not move up and down when the movable tank moves up and down regulates the first link via the sliding wheel. The link does not move up and down as a whole while keeping the X-shaped crossing angle between the first link and the second link constant, but the first link moves up and down by the support via the sliding wheel. While being regulated, the lower end of the first link is pivotally fixed to the bottom of the movable tank and the lower end of the second link is slidably connected to the bottom of the movable tank. By moving up and down, the first link is pivotally fixed to the bottom of the movable tank. A force is applied to the lower end, and the cross link in which the first link and the second link are pivotally attached in an X shape is the first link and the lower end of the second link or the first link. The lower end of the link and the upper end of the second link are deformed so as to be separated or approached in the vertical direction, the upper end of the first link is slidably connected, and the upper end of the second link is rotated. A stretcher receiving base that is freely fixed moves up and down in a direction opposite to that of the movable tank .

In the bathing apparatus according to claim 2, when the stretcher moves up and down as the movable tank moves up and down , the movable tank moves up and down in the vertical direction, whereas the sliding wheel regulates the first link in the vertical direction. Therefore, the ratio of the lift of the stretcher held by the cross link via the stretcher cradle is the ratio of the lift of the stretcher to the lift of the movable tank. It is characterized in that it is smaller than the ratio of the amount of elevation.

  The bathing apparatus according to claim 3 is characterized in that the elevating speed of the stretcher is slower than the elevating speed of the movable tank.

  According to invention of Claim 1 and Claim 2, since the raising / lowering amount of a stretcher is small compared with the raising / lowering amount of a movable tank, it is hard to receive the sense that the bather itself raises / lowers, and it is hard to feel the anxiety by raising / lowering.

  According to invention of Claim 3, since the raising / lowering speed of a stretcher is slow compared with the raising / lowering speed of a movable tank, the bather feels that it started moving slowly at the start of raising / lowering, and it is hard to feel anxiety by raising / lowering.

The movable tank lifting / lowering means 30 is provided with a hydraulic cylinder 34, and the link 36 and the link 38 are expanded and contracted around the pivot 42 by the hydraulic pressure of the hydraulic means 32 to raise and lower the movable tank 6. The movable tank lifting / lowering means 30 does not need to be in the form of a cross link as in the present embodiment, and is limited by the structure as long as it is a lifting / lowering means capable of moving up and down the movable tank 6 in which hot water is stored. Is not to be done.

  The support column 12 is cylindrical and stands up from the base 10 and penetrates the bottom 6b of the movable tub 6 in a watertight and slidable manner by a watertight structure (not shown). A cylindrical sensor pole 14 protrudes from the upper end of the column 12 that protrudes toward the inner wall 6a side of the movable tank 6, and the upper end of the sensor pole 14 is fixed to the back surface of a stretcher receiving base 80 (described later) with screws 16. Yes. The sensor pole 14 penetrates the upper end of the column 12 in a watertight and slidable manner by a watertight structure (not shown), and the inside of the sensor pole 14 and the inside of the column 12 communicate with each other. A sensor 18 is provided inside the upper end of the sensor pole 14, and the wiring of the sensor 18 passes from the inside of the sensor pole 14 to the inside of the support column 12 and between the fixed tank 4 and the movable tank 6. It is connected to a control means (not shown) provided. With such a structure, the sensor 18 moves up and down integrally with the sensor pole 14 at a position close to the stretcher receiving base 80.

  A cross link 50 is provided on the tank inner wall 6 a side of the bottom 6 b of the movable tank 6. The cross link 50 has a pantograph shape in which the first link 52 and the second link 58 are pivotally attached to the X axis in the pivot 70. The lower end of the first link 52 is pivotally supported by a fixed base 62 provided on the tank inner wall 6a side of the bottom 6b of the movable tank 6 with a rotation shaft 52a. The upper end of the first link 52 is pivotally supported by a slide base 68 having a substantially U-shaped cross section provided on the bottom surface of the plate-like stretcher receiving base 80 via a slide shaft 56. The second link 58 is pivotally supported by a rotation base 58 a on a fixed base 66 provided at the upper end on the bottom surface of the stretcher receiving base 80. Further, the lower end of the second link 58 is pivotally supported by a slide base 64 having a substantially U-shaped cross section provided on the tank inner wall 6 a side of the bottom 6 b of the movable tank 6 via a slide shaft 60. .

  A sliding wheel 22 adjacent to the first link 52 of the projecting portion of the support column 12 toward the inner wall 6a of the movable tank 6 is provided. Further, a sliding groove member 54 having a substantially U-shaped cross section is provided along the extending direction of the first link 52 on the support 12 side of the first link 52. The sliding ring 22 of the support column 12 is in sliding contact with the sliding groove member 54 of the first link 52, so that the first link 52 is slidably connected to the support column 12.

  Two parallel rails 82 are provided on the upper surface of the stretcher receiving table 80. The rail 82 is for sliding the stretcher 90 on the stretcher receiving base 80 in a state where the connecting portion 96 provided on the stretcher base 92 on the bottom surface of the stretcher 90 is straddled. Above the stretcher base 92 of the stretcher 90, a mat-like supine portion 98 and a headrest 98a on which a bather lies are provided. Further, when the stretcher 90 is at the center of the stretcher cradle 80 (position where the stretcher 90 may be raised and lowered in the movable tank 6), the bottom surface of the stretcher cradle 80 at a position directly above the sensor 18 A magnet 94 capable of detecting 18 is provided.

  Next, operation | movement of such a bathing apparatus 1 is demonstrated. First, as shown in FIG. 1, the bather is prepared for bathing in a state where the movable tank 6 is at the position of the base 10 and the stretcher receiving base 80 protrudes above the movable tank 6. Actually, at first, the stretcher 90 is not placed on the stretcher receiving stand 80, and the stretcher 90 is placed on a stretcher that holds the stretcher 90 (not shown) in a self-propelled manner. The patient lies on the stretcher 90 placed on the stretcher. When bathing, the stretcher 90 is placed alongside the stretcher 90 on the bathing apparatus 1, and the height of the stretcher is adjusted to the height of the stretcher cradle 80. Next, the position of the stretcher 90 on which the bather lies is adjusted to a position where the rail 82 of the stretcher cradle 80 and the connecting portion 96 match. Then, the stretcher 90 is slid along the rail 82 in the direction of the stretcher cradle 80, and the stretcher 90 is moved to the stretcher cradle 80. When the stretcher 90 is arranged at the center of the stretcher receiving base 80, a lock (not shown) is applied, and the stretcher 90 is fixed to the stretcher receiving base 80.

  Next, a bathing support person operates an operation unit (not shown) to start raising the movable tank 6 and lowering the stretcher 90 (the stretcher support 80). Specifically, the hydraulic cylinder 34 of the movable tank lifting / lowering means 30 is operated by the hydraulic pressure from the hydraulic means 32 and starts to extend the links 36 and 38 in the folded state upward. As the hydraulic cylinder 34 operates, the link 36 and the link 38 become substantially X-shaped, and the movable tank 6 starts to rise in conjunction with this (see FIG. 3).

  When the movable tub 6 starts to rise, the cross link 50 that was initially substantially X-shaped starts to deform. This is because the bottom 6b of the movable tank 6 on which the lower side of the cross link 50 is supported rises while the first link 52 slides while the column 12 stands up from the base 10 and the height and position do not change. This is because a force is applied to the cross link 50 because it is connected to the support column 12 via the driving wheel 22. Specifically, while the movable tank 6 is raised, the distance between the bottom 6b of the movable tank 6 and the connecting shaft 20 of the support column 12 is shortened. Since it is supported, the cross link 50 starts to deform in the direction of closing up and down. Here, the lower end of the first link 52 and the upper end of the second link 58 are pivotally supported by the rotation shafts 52a and 58a, respectively. The lower end of the second link 58 is slidably supported by the slide shafts 56 and 60 and slides in a direction away from the rotation shafts 52a and 58a.

  At this time, the connecting shaft 20 that connects the cross link 50 and the support column 12 is slidably in contact with the first link 52 via the sliding wheel 22, so that the position of the sliding wheel 22 is the first link. Thus, it slides in the direction of the lower end of the first link 52 along the sliding groove member 54. Here, in the bathing apparatus 1 of the present embodiment, the support column 12 is not connected to the pivot 70 of the cross link 50 unlike the conventional bathing apparatus, and the connection position of the support column 12 and the cross link 50 is the first position. Since the movable tank 6 moves obliquely along one link 52, the distance that the movable tank 6 ascends does not coincide with the distance that the cross link 50 is deformed and the stretcher support 80 descends. The distance by which the stretcher support 80 is lowered is shorter than the distance by which the movable tank 6 is raised.

  When the movable tank 6 is completely raised by the movable tank lifting / lowering means 30, the first link 52 and the second link 58 of the cross link 50 are folded so as to overlap each other, and the stretcher receiving base 80 is the bottom 6b of the movable tank 6. (FIG. 4). In this state, the raising and lowering of the movable tub 6 and the stretcher 90 (the stretcher cradle 80) are stopped, and the bather is immersed in hot water and bathes.

  When bathing is completed, a bathing support person operates an operation unit (not shown) to start the lowering of the movable tub 6 and the lifting of the stretcher 90 (the stretcher support 80). Specifically, contrary to the case described above, the links 36 and 38 in a state where the hydraulic cylinder 34 of the movable tank lifting / lowering means 30 is substantially X-shaped start to shrink downward. As the hydraulic cylinder 34 operates, the link 36 and the link 38 are folded, and the movable tub 6 starts to move downward (see FIG. 3).

  When the movable tub 6 starts to descend, the folded cross link 50 starts to be deformed so as to be substantially X-shaped. This is because the bottom 6b of the movable tub 6 supported by the lower side of the cross link 50 is lowered while the support 12 is standing from the base 10 and the height and position thereof are not changed, while the first link 52 is slid. This is because a force is applied to the cross link 50 because it is connected to the support column 12 via the driving wheel 22. Specifically, when the movable tank 6 is lowered, the distance between the bottom 6b of the movable tank 6 and the connecting shaft 20 of the support column 12 is increased, so that the first link 52 is moved by the support column 12 via the sliding wheel 22. Since it is supported, the cross link 50 begins to deform in the direction of opening up and down. Here, the lower end of the first link 52 and the upper end of the second link 58 are pivotally supported by the rotation shafts 52a and 58a, respectively. The lower end of the second link 58 is slidably supported by the slide shafts 56 and 60 and slides in a direction approaching the rotation shafts 52a and 58a.

  At this time, the connecting shaft 20 that connects the cross link 50 and the support column 12 is slidably in contact with the first link 52 via the sliding wheel 22, so that the position of the sliding wheel 22 is the first link. Thus, the first link 52 slides along the sliding groove member 54 of the first link 52.

  When the movable tank 6 is lowered by the movable tank lifting / lowering means 30, the first link 52 and the second link 58 of the cross link 50 extend in a substantially X shape, and the stretcher support 80 is located above the movable tank 6. (FIG. 1). In this state, raising and lowering of the movable tank 6 and the stretcher 90 (the stretcher support 80) are stopped, and a lock (not shown) that fixes the stretcher 90 to the stretcher support 80 is removed. Then, the stretcher 90 is slid on the rail 82 and is moved to a stretcher (not shown) placed on the bathing apparatus 1. Thereby, use of the bathing apparatus 1 is complete | finished.

  As mentioned above, according to the bathing apparatus 1 in this Embodiment, since the raising / lowering amount of the stretcher 90 (the stretcher receiving stand 80) is less than the raising / lowering amount of the movable tank 6, the feeling that the bather himself is going up and down. It is hard to receive, and it is hard to feel anxiety by going up and down. Moreover, since the ascending / descending speed of the stretcher 90 (the stretcher receiving base 80) is slower than the ascending / descending speed of the movable tub 6, the bather feels that he / she began to move slowly at the start of ascending / descending and hardly feels anxiety due to the ascending / descending. Actually, since the cross link 50 starts to be folded only after the movable tub 6 starts to move, the movement of the stretcher 90 becomes a slow start, and it is possible to suppress anxiety to the bather. In particular, in bathing apparatus 1 of the present embodiment, the stretcher 90 (stretcher cradle 80) has a lifting / lowering distance of about one-half that of movable tank 6 and the stretcher 90 (stretcher cradle 80). The rate of raising and lowering is determined to be about one half of the rate of raising and lowering the movable tank 6, and this ratio makes it difficult for bathers to feel uneasy due to raising and lowering.

  Moreover, in the bathing apparatus 1 of this Embodiment, the height (A of FIG. 5) of the upper edge of the movable tank 6 is made to become the range of about 930 mm-about 960 mm from the floor surface f at the time of the highest rise. . If the height of the movable tank 6 is the highest, the height of the upper edge of the movable tank 6 is the elbow head height of the bathing supporter (the upper arm is drooped naturally, and the elbow is at a right angle). The vertical height from the floor surface to the lower edge of the forearm (when the forearm is stretched horizontally forward with the palm of the bending side facing inward) is almost equal to or lower than the forearm.

  And the raising / lowering stroke of the movable tank 6 is about 270 mm-about 330 mm (B of FIG. 5), and the raising / lowering stroke of a stretcher is about 135 mm-about 167 mm (C of FIG. 5). Within this stroke range, the bather is less likely to feel anxiety due to elevation.

  As described above (see FIG. 6), the bathing apparatus 1 according to the present embodiment includes a sensor pole 14 that is a cylindrical member that protrudes from the inside of the upper end of the column 12 so as to be connected to the stretcher receiving table 80, The sensor 18 is provided inside the end of the pole 14 on the stretcher receiving base 80 side. The sensor 18 detects whether or not the stretcher 90 is at a predetermined position of the stretcher receiving base 80 (a position where the stretcher 90 may be raised and lowered within the movable tank 6). Specifically, when the stretcher 90 as shown in FIG. 6B is in a position where it can be moved up and down in the movable tub 6, the magnet 94 comes directly above the sensor 18 and the sensor 18 moves to the magnet 94. The control means (not shown) raises and lowers the movable tank 6 and the stretcher receiving table 80 by the detection of the sensor 18.

  On the other hand, when the stretcher 90 as shown in FIG. 6C is in a position where the stretcher 90 should not be moved up and down in the movable tank 6 (for example, a position where the stretcher 90 collides with the movable tank 6). The magnet 94 does not come directly above the sensor 18, and the sensor 18 cannot detect the magnet 94. In this case, a control means (not shown) regulates the movable tank 6 and the stretcher receiving table 80 not to be raised or lowered. Thus, the sensor 18 detects whether or not the stretcher 90 is at a predetermined position of the stretcher cradle 80, so that careless lifting of the stretcher 90 and the movable tub 6 is restricted, thereby ensuring safety. .

  Further, the sensor pole 14 penetrates the upper end of the support column 12 in a watertight and slidable manner, and has a sensor 18 inside the end portion of the sensor pole 14 on the stretcher receiving base 80 side. -Since it is connected to the control means (not shown) provided between the fixed tank 4 and the movable tank 6 from the inside of the pole 14 through the inside of the column 12, the sensor 18 and its wiring may get wet with hot water. In addition, wiring is easy.

  As described above, it is possible to provide a bathing apparatus that is less susceptible to the sense that the bather is moving up and down and is less likely to feel anxiety due to the lifting.
