Some forms of physical disabilities such as emphysema and other respiratory diseases, hiatal hernia, circulatory impairments, make it highly desirable, if not necessary, that persons subjected to such disabilities rest and/or sleep with their heads or feet in an elevated position. “Mattress elevating device”, invented by John J. Bradley and Frances L. Bradley, serves the disabled patients their needs with respect to their treatment at home. This invention was patented by the USPTO on 9th January 1980, bearing the patent number US4181989A.
This invention relates to a device insertable between the head or foot portions of a bed mattress and a box spring for holding the mattress in a raised position. The disabled persons are accommodated in hospital beds where the head or foot portion of the bed can be adjusted upwardly to any desired position.
The principal object of this invention is that the components can be assembled and disassembled easily and quickly without using any tools. After disassembling, they can be packed in a conventional suitcase thereby enabling a person, who must rest and/or sleep with the head in an elevated position, to travel comfortably with the assurance that he has the means for quickly and easily modifying a bed for suitable head elevation. Further, it is simple and economical to manufacture.
