Independent Claim
104 words
A lift and transport device comprising: ground engaging wheels; a horizontally disposed base supported on said wheels; a horizontally disposed plate rotatably mounted on said base; a vertically extendable mast secured to said plate; a support assembly secured to said mast and projecting outwardly therefrom; a support element secured to said assembly for supporting a patient; power means operatively connected to said mast for vertically extending said mast; and a rotation limit device interconnected between said plate and said base to limit the degree of rotation of said plate to provide that said support assembly and element is always substantially disposed over said plate.
Claim 2
Dependent Claim
104 words
A lift and transport device comprising: ground engaging wheels; a horizontally disposed base supported on said wheels; a horizontally disposed plate rotatably mounted on said base; a vertically extendable mast secured to said plate; a support assembly secured to said mast and projecting outwardly therefrom; a support element secured to said assembly for supporting a patient; power means operatively connected to said mast for vertically extending said mast; and a rotation limit device interconnected between said plate and said base to limit the degree of rotation of said plate to provide that said support assembly and element is always substantially disposed over said plate.
Claim 3
Dependent Claim
78 words
A lift and transport device as defined in claim 1, wherein said rotation limit device comprises an arcuate indent formed in said plate and facing said base, a base hole formed in said base which is in alignment with said indent as said plate is rotated relative to said base; a pin disposed in said base hole and projecting into said indent thus permitting said plate to rotate through an arc equal to the length of said indent.
Claim 4
Dependent Claim
90 words
A lift and transport device as defined in claim 2 and including a control means operatively interconnected to said pin to move said pin vertically, said plate having at least one hole formed therein in communication with said indent, and said pin secured on one end to said control means with the other end thereof disposed in said at least one hole thus preventing said plate from being rotated, said control means movable to a position wherein said pin other end is moved out of said at least one hole.
Claim 5
Dependent Claim
50 words
A lift and transport device as defined in claim 3 wherein said base comprises a rectangular planar section and a pair of spaced coplanar legs affixed to and extending outwardly therefrom, wherein the space between said legs is provided to permit said legs to straddle the base of a commode.
Claim 6
Dependent Claim
52 words
A lift and transport device as defined in claim 3 wherein said support assembly comprises a generally U shaped support bar having a middle section and two substantially parallel end sections and a collar secured to said mast and to said middle section, wherein said support element is interconnected between said legs.

Dependent Claim
78 words
A lift and transport device as defined in claim 4 wherein said mast comprises an inner post secured on one end to said plate with the other end thereof projecting vertically therefrom, and an outer post telescopically mounted on said inner post, wherein said support assembly is secured to said outer post and said power means is operable to cause said outer post to stroke out on said inner post and to stroke back on said inner post.
Claim 8
Dependent Claim
50 words
A lift and transport device as defined in claim 6 wherein said base comprises a rectangular planar section and a pair of spaced coplanar legs affixed to and extending outwardly therefrom, wherein the space between said legs is provided to permit said legs to straddle the base of a commode.
Claim 9
Dependent Claim
52 words
A lift and transport device as defined in claim 7 wherein said support assembly comprises a generally U shaped support bar having a middle section and two substantially parallel end sections and a collar secured to said mast and to said middle section, wherein said support element is interconnected between said legs.
