Effects of the Invention As described above, according to the elevating bathing device of the present invention, by operating the actuator, one end of the actuator causes the first swing link and the third swing link to swing in the same direction. The connecting link moves the first support body vertically while swinging in the opposite direction to the first swing link, and at the same time, the first support link swings in the same direction as the first swing link. While moving, move the second support vertically, and
The support link swings in the opposite direction to the first support link as the first support moves in the vertical direction, and the end of the second support link moves on the bottom of the bathtub body, causing the actuator to move in the opposite direction. The other end connects the fifth swing link and the sixth swing link to the first
The connecting link moves in the opposite direction to the actuator as the sixth swing link swings, and the second swing link and the fourth swing link move in the opposite direction to the actuator. swings in the same direction as the first swing link as the connecting link moves, so that the wash basin is moved relative to the bathtub body as the first support and second support move in the vertical direction. It can be raised and lowered.

Furthermore, when the washstand is raised from below inside the bathtub body, the end of the second swing link is located above the straight line connecting the second shaft and the end of the first swing link. , the second swing link acts as a resistance to swing in the same direction as the first swing link of the articulating link, and the other end of the actuator resists the swing of the fifth swing link and the sixth swing link in the same direction. The connecting link moves in the opposite direction to the actuator as the sixth swinging link swings, and the second swinging link and the fourth swinging link move in the direction opposite to the actuator as the sixth swinging link moves. Since the connecting link swings in the opposite direction to the first swing link, the connecting link can swing in the opposite direction to the first swing link by the second swing link, and one end of the actuator swings in the opposite direction to the first swing link. Since the link and the third swing link swing in the opposite direction to the articulating link, the articulating link smoothly swings in the opposite direction to the first swing link, and the relationship between the first swing link and the articulating link is Interference can be prevented.

In addition, it is also possible to raise and lower the washing basin relative to the bathtub body by operating the foot pedal, and the actuator or foot pedal can be freely selected depending on the situation. By arranging a gas spring on the outside of the side and connecting the moving rod of the gas spring to the first swing link, the proportion of the thrust of the actuator can be reduced, making it possible to downsize the hydraulic cylinder and reduce manufacturing costs. It is possible to make it inexpensive.

``According to claim 1'' is added next to ``of the present invention''. (8) Add the following sentence to the end of page 49 of the same. "Furthermore, according to the elevating bathing device according to claim 2 of the present invention, by operating the actuator, the operating rod of the actuator swings the first swinging link, and the articulated link swings the first swinging link. At the same time, the first support link moves the second support up and down while swinging in the same direction as the first swing link. The second support link swings in the opposite direction to the first support link as the first support moves in the vertical direction, and the end of the second support link swings in the direction opposite to the first support link. Since the bottom of the main body is moved and the second swing link swings in the same direction as the first swing link, the washing table can be moved in the vertical direction of the first support and the second support. In addition, by operating the foot pedal with your foot and moving it up and down, the support arm of the foot pedal swings, and the first swing link also swings. It swings in the same direction as the support arm, the actuator acts as a shock absorber, and the wash basin moves up and down relative to the bathtub body, so the actuator or foot pedal can be used to raise and lower the wash basin relative to the bathtub body. The foot pedal can be freely selected according to the situation.''
