Abstract
Abstract A chair for immobile patients. The chair has a high back portion, a seat portion that provides a toilet function, and a foot rest portion. The chair is specifically designed so that it is easily maneuvered from its reclined position to its upright position even when a patient is strapped therein. A pair of detachable auxiliary legs are provided that can be added to convert the chair into a wheel chair. The auxiliary legs can also be employed to stabilize the chair against lateral tipping when the chair is in its upright position on the edge of a bed. The seat portion is removable so that a portable toilet is thereby provided independently of the balance of the structural features of the chair. A pair of vertically spaced roller members, interconnected by a continuous belt, are provided to permit easy maneuvering of the chair relative to the surface of a bed when the chair is in its reclined position. The chair permits one person of ordinary strength to move an immobile patient, in the absence of hoists or other mechanical aids.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
355 words
A chair for immobile or substantially immobile patients, of the type having an elongate, vertically disposed back portion, a horizontally disposed seat portion formed integrally therewith, a vertically disposed leg rest portion formed integrally therewith, a horizontally disposed foot rest portion formed integrally therewith, and a pair of upstanding forward leg members operatively connected to said foot rest portion, wherein the improvement comprises: a pair of upstanding, detachably mounted auxiliary leg members disposed rearwardly of said forward leg members, said chair being used as a seat when disposed in an upright position on the edge of a bed and being used as a wheel chair when said auxiliary legs have been attached thereto, a first coupling means comprising upstanding first and second sleeve members disposed rearwardly of said forward leg members, each sleeve member adapted to telescopically receive an associated one of said auxiliary leg members, a pair of vertically spaced, rotatably mounted roller members disposed rearwardly of the back portion of said chair, a continuous belt member disposed in interconnecting relation around said roller members so that said chair, when in its reclining position can be moved relative to a bed surface, by engagement of said roller members and said belt member on the bed surface, a forward cross bar member transversely disposed in interconnecting relation between transversely spaced portions of said chair that at least in part define the seat portion of said chair, a rearward cross bar member spaced rearwardly of the forward cross bar member, and transversely disposed in interconnecting relation between said transversely spaced portions of said chair, a second coupling means disposed adjacent said rearward crossbar member, rearwardly thereof, said second coupling means comprising a first and second sleeve member, both of said sleeve members telescopically receiving a respective end of said auxiliary leg members, and said second coupling members aligned so that when said auxiliary leg members are releasably attached thereto, said auxiliary leg members extend laterally relative to said chair, from the lowermost surface thereof, thereby stabilizing the chair when it is in its upright configuration on the edge of a bed, being used as a seat.
Claim 2
Dependent Claim
355 words
A chair for immobile or substantially immobile patients, of the type having an elongate, vertically disposed back portion, a horizontally disposed seat portion formed integrally therewith, a vertically disposed leg rest portion formed integrally therewith, a horizontally disposed foot rest portion formed integrally therewith, and a pair of upstanding forward leg members operatively connected to said foot rest portion, wherein the improvement comprises: a pair of upstanding, detachably mounted auxiliary leg members disposed rearwardly of said forward leg members, said chair being used as a seat when disposed in an upright position on the edge of a bed and being used as a wheel chair when said auxiliary legs have been attached thereto, a first coupling means comprising upstanding first and second sleeve members disposed rearwardly of said forward leg members, each sleeve member adapted to telescopically receive an associated one of said auxiliary leg members, a pair of vertically spaced, rotatably mounted roller members disposed rearwardly of the back portion of said chair, a continuous belt member disposed in interconnecting relation around said roller members so that said chair, when in its reclining position can be moved relative to a bed surface, by engagement of said roller members and said belt member on the bed surface, a forward cross bar member transversely disposed in interconnecting relation between transversely spaced portions of said chair that at least in part define the seat portion of said chair, a rearward cross bar member spaced rearwardly of the forward cross bar member, and transversely disposed in interconnecting relation between said transversely spaced portions of said chair, a second coupling means disposed adjacent said rearward crossbar member, rearwardly thereof, said second coupling means comprising a first and second sleeve member, both of said sleeve members telescopically receiving a respective end of said auxiliary leg members, and said second coupling members aligned so that when said auxiliary leg members are releasably attached thereto, said auxiliary leg members extend laterally relative to said chair, from the lowermost surface thereof, thereby stabilizing the chair when it is in its upright configuration on the edge of a bed, being used as a seat.
Claim 3
Dependent Claim
83 words
The chair of claim 1 further comprising, a third, vertically disposed, coupling means disposed adjacent said respective leg rest portions of said chair, rearwardly thereof, a pair of hook-shaped members slideably received within respective ones of said third coupling means, bias means for imparting tension to both of said hook-shaped members so that they have a tendency to retract into said third coupling means, so that the chair may be stabilized by hooking said hook-shaped members to the underside of a bed railing.
Claim 4
Dependent Claim
18 words
The chair of claim 2, wherein said leg members associated with the foot rest portion are vertically adjustable.
Claim 5
Dependent Claim
75 words
The chair of claim 3, wherein a pair of elongate, flexible strap members are fixedly secured at their respective ends to the uppermost rail of said chair, on transversely spaced portions thereof, and wherein the distal ends of said members are releasably secured to the frame of said chair adjacent the seat portion thereof so that a patient can be secured in said chair by securing said strap members in crossing relation to one another.
