Abstract
Abstract A device for rising lifting and moving patients or other persons completely or partly incapable of moving, including a stand with at least four arms at some distance from each other, said arms being provided with turntable holding or supporting elements at their ends and at least the outer arms being further provided with means for moving their respective holding elements further from and nearer to the adjacent elements. Said holding elements are formed as elongated plates with rounded cross-section and the outer arms are preferably divided into two partial arms pivotally connected to each other. All arms may be connected to a common horizontal beam vertically movable with the help of hydraulic cylinders.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
86 words
A lifting device which comprises a portable base means and a plurality of motorized adjustable arm units supported by said base means and disposed to engage and thereby support the object to be lifted, said arm units each having a holding element disposed for supportive contact with said object, at least one of said arm units having motorized pivot connection means moveable with the arm unit and accommodating adjustment of the position of the holding element of that arm unit by independent horizontal and vertical movements.
Claim 2
Dependent Claim
86 words
A lifting device which comprises a portable base means and a plurality of motorized adjustable arm units supported by said base means and disposed to engage and thereby support the object to be lifted, said arm units each having a holding element disposed for supportive contact with said object, at least one of said arm units having motorized pivot connection means moveable with the arm unit and accommodating adjustment of the position of the holding element of that arm unit by independent horizontal and vertical movements.
Claim 3
Dependent Claim
31 words
A lifting device according to claim 1 wherein said base means includes a moveable beam and said arm units are connected to said beam in spaced-apart relation therealong for movement therewith.
Claim 4
Dependent Claim
56 words
A lifting device according to claim 1 including a double-section arm unit having an inner arm section supported at one end from said base means for pivotal movement relative thereto about a first axis, and an outer arm section pivotally connected at one end to said inner arm section for pivotal movement about a second axis.
Claim 5
Dependent Claim
26 words
A lifting device according to claim 1 wherein said holding elements extend in a cantilevered relationship from their respective arm units and are pivotally connected thereto.
Claim 6
Dependent Claim
29 words
A lifting device according to claim 1 including fluid powered motorized pivot connection means associated with said arm units and operable to adjust the positions of said holding elements.
Claim 7
Dependent Claim
151 words
A lifting device which comprises a portable base means and a plurality of adjustable arm units supported by said base means and disposed to engage and thereby support the object to be lifted, said arm units each having a holding element disposed for supportive contact with said object, at least one of said arms having pivot connection means accommodating adjustment of the position of the holding element of that arm unit by independent horizontal and vertical movements, said base means including a moveable beam and said arm units being connected to said beam in spaced-apart relation therealong for movement therewith, said plurality of arm units including a pair of double-section arm units each having an iNner arm section pivotally connected to a corresponding end portion of said moveable beam, and an outer arm section pivotally connected to said inner arm section, said double-section arm units being adjustable independently of each other.
