  • Patent number: 7900292
    Abstract: In summary, this device offers many unique features advantageous to the user. This device will be economical to buy and is light and easy for one person to handle. This device is simple and easy to be placed in a standard bathtub and is convenient and easy to operate by the user or an assistant, This device will be comfortable and relaxing as it supports the entire body of the user. This device is convenient and easy to keep in a sanitary condition and easy to remove from the bathtub as desired. The innovations I have made to Ashby's device of 1961 U.S. Pat. No. 2,968,814 renders it feasible to manufacture and market. The fact that it was in public Domain these many years and has not been taken seems to be an indication that it wasn't deemed a feasible item. My innovation of stabilizing platform 20 and being able to eliminate the awkward, vertical, inverted U shaped frame and sides and attachments thereto has made this device simple and economical to produce and market.
