Is provided.

  The blindfold plate 19 has a substantially inverted tray shape having an opening below, and is supported by a support member 50 provided at an appropriate position on the lower surface of the guide rail 21 and protrudes further forward than the front end of the guide rail 21 to move up and down. It has a function to relieve fear by blocking the downward view of the bather on the part 6. In addition, a large number of water passage holes 23 are formed in the surface of the blindfold plate 19 so as to reduce water resistance applied to the elevating unit 6 that moves up and down along the frame 4.

  Next, the elevating / lowering means 24 that moves the elevating unit 6 up and down along the frame 4 will be described. A drive motor 7 is fixedly installed on the right side (right side in FIG. 6) on the base plate 8 of the installation portion 2, and a drive pulley 25 is connected to a driving shaft 7 a of the drive motor 7. An interlocking shaft 26 is mounted between the left and right standing members 9 in a direction parallel to the driving shaft 7 a, and is driven by forward and reverse rotation of the driving pulley 25 at one end of the interlocking shaft 26 on the same side as the connecting side of the driving pulley 25. A driven pulley 28 having the same diameter as that of the driving pulley 25 that rotates is fixed so as to be on the same plane as the driving pulley 25. In addition, belt winding pulleys 29 around which belt-like belts 27 are wound are fixed in the vicinity of both ends of the interlocking shaft 26.

  The belt 27 wound around each belt winding pulley 29 is hung on a relay pulley 30 provided in the vicinity of the bent end of the bent plate 11, and then the end of the belt 27 is attached to the stopper 48 at the upper part of the holding plate 16. The elevating part 6 is supported by the belt 27 in a fishing support state. Therefore, the driven pulley 28 and the belt winding pulley 29 are rotated by driving the drive motor 7 and rotating the drive pulley 25. When the belt-like belt 27 is unwound from the belt-winding pulley 29 due to the rotation of the belt-winding pulley 29, the elevating part 6 moves downward along the frame 4, and conversely when the belt-like pulley 29 is wound up, the elevating part 6 Will move up.

  As described above, each frame 4 has a configuration in which one end of the first pipe-shaped member 13 is fitted and inserted into the other end of the second pipe-shaped member 12, so that there is a step at the fitting portion of both pipe-shaped members. The bath lift apparatus 1 according to the present invention eliminates the step so that the lift 6 does not receive an impact caused by the step when the lift 6 passes through the step position. Means 31 are provided. Hereinafter, the step eliminating means 31 will be described.

  As shown in FIGS. 2 and 4, a substantially hexagonal side view that extends over a predetermined range in the fitting insertion direction of both pipes with the fitting portion of the second pipe-like member 12 and the first pipe-like member 13 being substantially the center. A step difference eliminating plate 32 having a shape is attached to the left and right outer peripheral surfaces of the second pipe-shaped member 12 so as to face each other. The level difference elimination plate 32 has a line-symmetric shape with respect to a line parallel to the center line of both pipe members, and a plate front side surface 32a and a plate rear side surface 32b extending along the fitting insertion direction of both pipe members are The center surface portion is formed in a curved surface that gently swells with respect to the both end surface portions, and the center surface portion is disposed so as to be located at the fitting portion of both pipe members.

  Next, when the elevating unit 6 at the upper limit position (the elevating unit 6 at the position in FIG. 4) moves downward, the rolling element 5 (lower left in FIG. 5) disposed at the front position with respect to the frame 4. Focusing on the rolling elements 5 arranged in the direction (hereinafter referred to as the forward rolling elements 5), the operation of the step eliminating means 31 will be described. As shown in FIG. 7, when the elevating part 6 starts to move downward, the small-diameter roller surface part 5 b of the front rolling element 5 rolls along the front outer surface of the second pipe-shaped member 12 (E state). When the descending movement of the elevating part 6 advances and the front rolling element 5 reaches the vicinity of the start end (upper end) of the step elimination plate 32, the small diameter roller surface part 5b is in contact with the plate front side surface 32a and the front rolling element 5 The large-diameter roller surface portion 5a comes into contact with the plate front side surface 32a (F state). When the downward movement further proceeds, the small-diameter roller surface portion 5b is separated from the front outer surface of the second pipe-shaped member 12 (G state).

  When the front rolling element 5 reaches the vicinity of the end (lower end) of the step eliminating plate 32, the small diameter roller surface portion 5b is in contact with the plate front side surface 32a while the small diameter roller surface portion 5a is in contact with the first pipe member 13. Abuts against the front outer surface (H state). Thereafter, the small diameter roller surface portion 5b rolls along the front outer surface of the first pipe-shaped member 13 (I state). A line segment JJ in FIG. 7 shows a part of the movement locus of the axial center of the front rolling element 5 accompanying the up-and-down movement of the elevating unit 6. This step eliminating means 31 eliminates the step even when the elevating part 6 passes through the step position formed at the fitting portion between the second pipe-shaped member 12 and the first pipe-shaped member 13, and the impact caused by the step. Therefore, the elevating unit 6 can smoothly move up and down without being hindered from moving up and down.

  Further, when the elevating part 6 is moved up and down along the outer surface of the second pipe-shaped member 12, the horizontality is maintained, but the elevating part 6 is moved from the outer surface of the second pipe-shaped member 12. When the first pipe-shaped member 13 is completely moved to the outer surface, the elevating part 6 is in a state where the whole is slightly inclined by about 3 ° from the horizontal plane in the direction in which the front side is inclined downward (in FIG. 5). For example, the state of the elevating part 6 indicated by C). Therefore, if the elevating part 6 is lowered to the lower limit position in this inclined state, a sufficient effective water depth cannot be secured for the bather. However, in the bathing lift device 1 according to the present invention, In order to prevent such inconvenience, horizontal return means 33 for returning the elevating part 6 to the horizontal state is provided in the other end (end) of the first pipe-shaped member 13 or in the vicinity thereof. .

  More specifically, the horizontal return means 33 has a concave member 34 (see FIG. 2) having a substantially concave shape when viewed from the front at the other end of the first pipe-shaped member 13 so as to have a concave shape. The two free end portions 34a of the 34 are screwed to the outer surfaces of the left and right of the first pipe member 13 with bolts or the like.

  Each free end portion 34a of the concave member 34 is formed in a substantially wedge shape in a side view, and the inclination angle of the front surface of the free end portion 34a with respect to the inner bottom surface 3b is set more gently than the inclination angle of the first pipe-shaped member 13 ( 4), when the elevating part 6 descends and reaches the vicinity of the lower limit position, the large-diameter roller surface part 5a of the front rolling element 5 rolls along the front surface of the free end part 34a of the concave member 34. The inclined lifting unit 6 returns to the horizontal state, and the lowering movement of the lifting unit 6 stops at the lower limit position (the state of the lifting unit 6 is indicated by D in FIG. 5).

  In FIG. 2, reference numeral 35 denotes a connecting member having a concave shape when viewed from the front, and by connecting both pipe-shaped members 13 at the other end of the first pipe-shaped member 13, each of the first pipe-shaped members 13 is connected. It plays a role of suppressing unintentional inadvertent rotation and the like. The connecting member 35 is arranged in an upwardly concave manner like the concave member 34, and the connecting member 35 is attached to the concave member 34 so that the vertical position can be finely adjusted. That is, the shaft portion is inserted into the long hole 51 that is cut and extended in the vertical direction of the surface of each free end portion 35 a of the connecting member 35, and the shaft portion tip side is screwed into the surface of the free end portion 34 a of the concave member 34. Via the two screw bolts 52 to be worn, the outer surface of each free end 35a is pressed against the surface of the free end 34a inside each concave member 34 and fixed (see FIGS. 1 and 2).

  Accordingly, when adjusting the expansion / contraction of the length of the first pipe-shaped member 13, the screw bolts 52 are loosened in advance, and as a result of the expansion / contraction adjustment, an unbalance occurs in the lengths of the left and right first pipe-shaped members 13. Even in such a case, the vertical position of the connecting member 35 can be finely adjusted within the range of the long hole 51, and the connection of the first pipe-like members 13 by the connecting member 35 is not hindered. .

  3, 43 is provided on the upper surface of the casing 22, and an operation panel on which various switches such as an ascending switch and a descending switch of the elevating unit 6 are disposed, and 44 is a predetermined interval from the rear surface of the installation unit 2 to the rear. It is a pair of left and right transport vehicle guide rails that are provided in parallel and project.

  Next, the usage method of the bath lift apparatus 1 is demonstrated. When performing the operation of installing the bathing lift device 1 in the bathtub 3, first, each member of the grounding leg 38, the connecting member 35, and the concave member 34 attached to the other end portion of the first pipe-shaped member 13 is used. Remove. The length of each first pipe-shaped member 13 is extended or shortened by appropriately rotating the first pipe-shaped member 13 in a predetermined direction while considering the depth of the bathtub 3 and the slope of the inner bottom surface 3b as necessary. Do the adjustment work. After finishing the adjustment of the lengths of both the left and right first pipe members 13, the members of the grounding leg 38, the connecting member 35, and the concave member 34, which have been removed before the operation, are attached to the first pipe members 13. Reattach to the other end and complete the installation work.

  A transport vehicle 39 on which a bather (not shown) is placed is approached from the rear of the installation unit 2 (for example, in the right direction in FIG. 8), and the installation unit 2 is placed along the side of the carriage 41 along the pair of left and right transport vehicle guide rails 44. The transport vehicle 39 is inserted into the predetermined position, and the carriage 41 is connected and connected to the installation unit 2. Thereafter, an operation of separating the seating part 40 from the carriage 41 is performed, and only the seating part 40 is caused to travel on the pair of joint rails 20 and is moved onto the guide rails 21 of the elevating part 6 (see FIG. 8). When the seating portion 40 reaches a predetermined position on the guide rail 21, a locking device (not shown) is actuated, and the seating portion 40 is locked and fixed to the guide rail 21.

  A lowering switch (not shown) provided on the operation panel 43 is pressed to drive the drive motor 7 of the elevating / lowering means 24, the belt 27 is fed out from the belt winding pulley 29, and the elevating part 6 is moved along the frame 4. And move it down. Even when the elevating part 6 passes through the fitting portion between the second pipe-shaped member 12 and the first pipe-shaped member 13, the step is eliminated by the action of the above-described step eliminating means 31. The elevating unit 6 is not strongly affected by the steps, and therefore, the bather on the elevating unit 6 does not feel afraid and can relax and relax in bathing.

  When the elevating part 6 reaches the vicinity of the lower limit position, the inclined elevating part 6 returns to the horizontal state by the action of the horizontal return means 33 described above, and the elevating part 6 reaches the lower limit position and stops while maintaining this horizontal state. . Therefore, the effective water depth of the bather can be sufficiently secured, and the bather can bathe by bathing in the hot water up to the shoulder.

  In the case of bathing, the lifting switch (not shown) is depressed, the drive motor 7 is driven, and the belt-like belt 27 is wound around the belt winding pulley 29, so that the elevating unit 6 moves up along the frame 4. . Even when the elevating part 6 moves up and down, the step eliminating means 31 acts, so that the elevating part 6 is strongly subjected to the impact caused by the step at the fitting site between the second pipe member 12 and the first pipe member 13. There is nothing. When the elevating part 6 reaches the upper limit position, the ascending movement automatically stops. After releasing the locking of the seating part 40, the seating part 40 is moved from the guide rail 21 onto the joint rail 20 and moved onto the carriage 41. Let them bathe.

  Moreover, even if it is a case where the bath lift apparatus 1 is moved from the bathtub 3 to another bathtub, after removing the connection member 35, the operation of rotating the first pipe-shaped member 13 in a predetermined direction causes the entire frame 4 to move. Since the length can be shortened, the length of the frame 4 is not bulky and the transportability is excellent.

  The present invention is not limited to the above-described embodiments, and various configurations can be adopted without departing from the spirit described in the claims.
