  • Patent number: 7111335
    Abstract: A bathtub 12 is supported by a movable unit 14 that vertically moves by the driving power of a motor and by rollers 13 running on a guide slope 15. When not used, the bathtub 12 is stored under a tank 11 in a close to upright position, so that the bathing aid occupies only a small space when not used. To use the bathing aid, the movable unit 14 is lowered and, accordingly, the rollers 13 roll down the guide slope 15. With this motion, the bathtub 12 changes its orientation from a position where the open top of the bathtub 12 is directed obliquely forward to a position where the open top is directed almost upward. The bathtub 12 is automatically driven by the electrical driving power of the motor; the caregiver has only to make some key operations. Thus, the workload on the caregiver is significantly reduced.

  • Patent number: 7107630
    Abstract: A bathing aid is designed to reduce the workload on the caregiver in bathing the physically challenged, elderly or similar persons requiring nursing care. The bathing aid is provided with an upward-opening cover for covering the open top of the bathtub except for an opening for allowing the bather to stick their head through. The cover is supported by arms urged upward by gas springs. The upward-opening cover allows the caregiver to stand whichever side of the bathtub and opens or closes the cover without difficulty. Furthermore, the cover's upward-opening structure is advantageous for reducing the installation space because it does not require the additional side space that would be necessary if the cover is constructed to open sideward.

  • Publication number: 20040034917
    Abstract: The present invention provides a bathing aid, which is reduced in size and does not occupy a large space when not used, and which significantly reduces the workload on caregivers. In an embodiment of the invention, a bathtub 12 is supported by a movable unit 14 that vertically moves by the driving power of a motor and by rollers 13 running on a guide slope 15. When not used, the bathtub 12 is stored under a tank 11 in a close to upright position, so that the bathing aid occupies only a small space when not used. To use the bathing aid, the movable unit 14 is lowered and, accordingly, the rollers 13 roll down the guide slope 15. With this motion, the bathtub 12 changes its orientation from a position where the open top of the bathtub 12 is directed obliquely forward to a position where the open top is directed almost upward. The bathtub 12 is automatically driven by the electrical driving power of the motor; the caregiver has only to make some key operations.
