Elevating convertible wheelchair

An elevating convertible wheelchair, comprising:

• a lower support frame means carrying a plurality of rotating wheels attached thereto;
• a plurality of telescoping leg means fixedly anchored at the their lower ends to the lower support frame means and extending vertically therefrom;
• a seat frame means carried by upper ends of the leg means;
• a backrest means hingedly attached to the seat frame means and moveable from a first, normally vertically oriented position in perpendicular relationship to the seat frame means to a second position, substantially co-planar with said seat frame means, said backrest means comprising an upper cross bar attached at its ends to a pair of parallel elongated tubular members;
• a secondary backrest support means hingedly attached to a free end of said backrest means and moveable between a normally co-planar position with said backrest means to a position substantially perpendicular to said backrest means, so as to support the free end of the backrest means when the wheelchair is converted to a flat bed;
• a means for elevating the seat frame means to a desired level, said elevating means being carried by the lower frame means;
• a connecting panel means secured to at least one side of the wheelchair for covering a space between the converted flat bed and an adjacent side of a regular patient bed;
• and
• a detachable headrest means adapted to be engaged with the backrest means, and wherein said headrest means comprises a pair of elongated rod members, a portion of each of which is telescopically retractably received in a corresponding rail member of the backrest means.

• a release means for releasing a locked position of the backrest means and allowing rotation of the backrest means into the second position;
• a means for elevating the seat frame means to a desired level, said elevating means being carried by the lower frame means;
• a detachable arm rest removably engageable with at least one of said leg means;
• and
• a connecting panel means secured to at least one side of the wheelchair for covering a space between the converted flat bed and an adjacent side of a regular patient bed.
