Abstract
A chair bed for supporting an invalid, wheelchair-bound or non-ambulatory person, which includes a seat portion and a hinged backrest attached to the seat portion for adjusting the reclining angle of the occupant, with conventional main wheels, optional rear wheels and 350 degree pivotable front wheels for rolling operation and directional control. The arm rests of the chair bed are pivotally adjustable in two sections and in a preferred embodiment, the seat portion of the chair bed is fitted with a frontal circular recess. A latch element is also provided in the chair bed frame for engaging and locking the chair bed to a receiver mechanism located in close proximity to a conventional or specially designed commode, in order to facilitate movement by the non-ambulatory chair bed occupant to and from the commode.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
