Abstract:
1. A portable commode, shower, and bath wheelchair apparatus, comprising: a first support frame comprising a first support rail, a second support rail, and four first leg assemblies, wherein the length of each first leg assembly can be separately adjusted, and wherein each first leg assembly comprises a wheel disposed on a distal end, and wherein a proximal end of each first leg assembly is hingedly attached to a different end of a different one of said first support rail and said second support rail, and wherein each first leg assembly can be moved, without using any tools, from a first configuration to second configuration, and from said second configuration to said first configuration wherein when a first leg assembly is placed in said first configuration the leg assembly is disposed within said first support frame, and when a first leg assembly is placed in said second configuration the leg assembly extends outwardly from said first support frame; a second support frame comprising a third support rail, a fourth support rail, and four second leg assemblies, wherein the length of each second leg assembly can be separately adjusted, and wherein each second leg assembly comprises a glide disposed on a distal end, and wherein a proximal end of each second leg assembly is hingedly attached to a different end of a different one of said third support rail or said fourth support rail, and wherein each second leg assembly can be moved, without using any tools, from a first configuration to second configuration, and from said second configuration to said first configuration, wherein when a second leg assembly is placed in said first configuration the leg assembly is disposed within said second support frame, and when a second leg assembly is placed in said second configuration the leg assembly extends outwardly from said second support frame; a mechanical interface comprising a first interface assembly comprising a fifth support rail, a first connector disposed on a first end of said fifth support rail, and a second connector disposed a second end of said fifth support rail, a second interface assembly comprising a sixth support rail, a third connector disposed on a first end of said sixth support rail, and a fourth connector disposed a second end of said sixth support rail; wherein said first connector can be releasably attached to said first support rail without using any tools, and wherein said second connector can be releasably attached to said third support rail without using any tools, such that said first support rail and said fifth support rail and said third support rail comprise a first contiguous support rail; and wherein said third connector can be releasably attached to said second support rail without using any tools, and wherein said fourth connector can be releasably attached to said fourth support rail without using any tools, such that said second support rail and said sixth support rail and said fourth support rail comprise a second contiguous support rail; a seat assembly comprising a plurality of attachment assemblies, wherein said seat assembly can be slidingly attached to both said first contiguous support rail and to said second contiguous support rail by said plurality of attachment assemblies wherein: said first support member, said second support member, said third support member, said fourth support member, said fifth support member, and said sixth support member, each comprise an identical support member radius of curvature and an identical support member circumference; each of said plurality of attachment assemblies comprises an identical aggregate arcuate surface, wherein said aggregate arcuate surface comprises an aggregate arcuate surface radius of curvature and an aggregate arcuate surface length; said support member radius of curvature equals said aggregate arcuate surface radius of curvature; said aggregate arcuate surface length is greater than the multiplication product of (0.5) and said support member circumference said first support member, said second support member, said third support member, said fourth support member, said fifth support member, and said sixth support member, each comprise a cylindrical member.
