Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
184 words
A lifting and transporting device for disabled persons comprising: a. a base member, b. a first substantially vertical column mounted on said base member, c. a second column telescopically mounted relative to said first column, d. a seat, e. said second column having a first means for supporting said seat in an operative position at a substantially right angle relative to said second column and for permitting movement of said seat to an inoperative position, f. said seat being saddle-shaped and having a narrow Part coupled to said first seat supporting means in close proximity to said second column, g. said second column having a second means located above said seat for supporting a pair of laterally spaced armrests in an operative position substantially parallel to each other and to a surface upon which the device rests, h. power means for displacing said second column relative to said first column, and i. means for operating said power means, said operating means being located approximately at the top of said second column for enabling a person sitting on the seat to operate the power means.
Claim 2
Dependent Claim
184 words
A lifting and transporting device for disabled persons comprising: a. a base member, b. a first substantially vertical column mounted on said base member, c. a second column telescopically mounted relative to said first column, d. a seat, e. said second column having a first means for supporting said seat in an operative position at a substantially right angle relative to said second column and for permitting movement of said seat to an inoperative position, f. said seat being saddle-shaped and having a narrow Part coupled to said first seat supporting means in close proximity to said second column, g. said second column having a second means located above said seat for supporting a pair of laterally spaced armrests in an operative position substantially parallel to each other and to a surface upon which the device rests, h. power means for displacing said second column relative to said first column, and i. means for operating said power means, said operating means being located approximately at the top of said second column for enabling a person sitting on the seat to operate the power means.
Claim 3
Dependent Claim
66 words
A device according to claim 1, wherein the means for displacing the columns is included within at least one of the columns and a knob is provided at the end of the second column, said knob being rotatably mounted around an axis substantially co-axial with the column and serving to cause the displacement of the columns at least in one displacement direction by the turning thereof.
Claim 4
Dependent Claim
28 words
A device according to claim 1, wherein the means for displacing the columns comprises a screw secured to one column, and a nut secured to the other column.
Claim 5
Dependent Claim
24 words
A device according to claim 1, wherein the columns form a cylinder and a piston in a lifting device actuated by a pressurized medium.
Claim 6
Dependent Claim
74 words
A lifting device according to claim 1, wherein the base comprises a front part having a pair of front wheels thereon and two arms pivotally mounted about substantially vertical axes on said front part, said arms carrying adjacent the free end thereof a pair of rear wheels in such a way that the distance between the rear wheels may be varied by pivoting the arms in a direction towards or away from each other.
Claim 7
Dependent Claim
42 words
A lifting device according to claim 5, wherein the arms are normally held substantially parallel to each other by a blocking means and have a distance between the rear wheels of the arms essentially corresponding to the distance between the front wheels.
Claim 8
Dependent Claim
43 words
A device according to claim 1, wherein the arm rests comprise a loop essentially having a U-shape, the body part of which is connected to the upper part of the second column and the legs of which extend backwardly relative to said colums.
Claim 9
Dependent Claim
79 words
A device according to claim 1, wherein the second column in the upper end thereof supports two essentially horizontally positioned guides for tubular shaped elements having stop members shaped as handles at their ends to limit the pushing movement of each element relative to the guides, whereby the guides are positioned at such a distance from each other and form such an angle with each other that the elements serve as arm rests for the person utilizing the device.
Claim 10
Dependent Claim
45 words
A device according to claim 8 including means for bridging said tubular shaped elements, means for displaceably fastening said bridging means on said tubular shaped elements at various locations therealong whereby said bridging means supports the back and stomach of the person utilizing the device.
Claim 11
Dependent Claim
25 words
A device as defined in claim 1 wherein said armrests are displaceable for movement to an inoperative position to facilitate the transfer of disabled persons.
Claim 12
Dependent Claim
84 words
A device according to claim 1, wherein the second column has a guide means parallel to the longitudinal direction thereof to guide a unit which is adjustable in the height direction and lockable in a desired distance between the foot rest and the seat independently of the displacement of the column, said unit in the lower part thereof comprising a rail having preferably laterally extending parts serving as a foot rest and the upper part of the unit having a mounting for the seat.
Claim 13
Dependent Claim
28 words
A device according to claim 11, wherein the distance between the foot rest and the seat is adjustable since the rail may be adjusted relative to the mounting.
Claim 14
Dependent Claim
23 words
A device according to claim 11, wherein the foot rest is telescopically supported and adjustable in the vertical direction relative to the seat.
Claim 15
Dependent Claim
89 words
A device according to claim 1, wherein the base compRises another two columns to support a water-closet seat having an open front, said water-closet seat with the main opening thereof being centered relative to the seat, said seat being of such a shape and dimension that it may be pushed down in a vertical movement through the main opening of the water-closet seat from above, whereby guides are provided in connection with said water-closet seat, columns and base for a collecting vessel that is insertable underneath the water-closet seat.
