Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
130 words
A device usable in diverse environments for positioning a worker adjacent to a structure in such a fashion that said worker can perform useful tasks, said device comprising: a shaped, rigid reaction surface adapted to generally conform to the back of said worker; said surface having extensions adapted to overlie the hip areas of said worker; fastening means for securing said surface to said worker; a single stabilizer arm having a proximal end, a proximal portion, and a distal end; at least one of said extensions having an adjustable connector attached thereto which is releasably connectable to said proximal portion; clamp means at said distal end for providing attachment to said adjacent structure, whereby, the orientation of the worker is adjustably securable by said worker with respect to said structure.
Claim 2
Independent Claim
130 words
A device usable in diverse environments for positioning a worker adjacent to a structure in such a fashion that said worker can perform useful tasks, said device comprising: a shaped, rigid reaction surface adapted to generally conform to the back of said worker; said surface having extensions adapted to overlie the hip areas of said worker; fastening means for securing said surface to said worker; a single stabilizer arm having a proximal end, a proximal portion, and a distal end; at least one of said extensions having an adjustable connector attached thereto which is releasably connectable to said proximal portion; clamp means at said distal end for providing attachment to said adjacent structure, whereby, the orientation of the worker is adjustably securable by said worker with respect to said structure.
Claim 3
Dependent Claim
17 words
The device of claim 1 wherein said surface comprises a portion of a pressure-suit for an astronaut.
Claim 4
Dependent Claim
19 words
The device of claim 1 wherein said surface comprises a back-pack shell suitable for underwater usage by an aquanaut.
Claim 5
Independent Claim
28 words
The device of any one of claims 1, 2, or 3 wherin said connector comprises a quick-release joint which may be alternately connected to either of said extensions.
Claim 6
Dependent Claim
30 words
The device of claim 4 wherein said connector further comprises a spherically adjustable joint with lock means for locking said connector at any given position within a range of positions.
Claim 7
Dependent Claim
12 words
The device of claim 5 wherein said lock means is hydraulically actuated.
Claim 8
Dependent Claim
31 words
The device of claim 6 wherein said arm has a diameter less than 1.50 inches (about 38 mm) and has a gripping means on said proximal portion for enhancing gloved-hand gripping.
Claim 9
Independent Claim
108 words
A device usable in diverse environments for positioning a worker adjacent to a structure in such a fashion that said worker can perform useful tasks, said device comprising: a shaped reaction surface for the torso of said worker; fastening means for securing said surface to said worker; a single stabilizer arm having a proximal end, a proximal portion, and a distal end; said surface having an adjustable connector attached thereto which is releasably connectable to said proximal portion; clamp means at said distal end for providing attachment to said adjacent structure, whereby, the orientation of the worker is adjustably securable by said worker with respect to said structure.
Claim 10
Independent Claim
108 words
A device usable in diverse environments for positioning a worker adjacent to a structure in such a fashion that said worker can perform useful tasks, said device comprising: a shaped reaction surface for the torso of said worker; fastening means for securing said surface to said worker; a single stabilizer arm having a proximal end, a proximal portion, and a distal end; said surface having an adjustable connector attached thereto which is releasably connectable to said proximal portion; clamp means at said distal end for providing attachment to said adjacent structure, whereby, the orientation of the worker is adjustably securable by said worker with respect to said structure.
Claim 11
Dependent Claim
26 words
The device of claim 1 whereby said stabilizer arm comprises a single, rigid, adjustable-length arm having a proximal end, a proximal portion, and a distal end.
Claim 12
Dependent Claim
25 words
The device of claim 8 wherein said connector comprises a quick-release joint which may be alternately connected to more than one site on said surface.
Claim 13
Dependent Claim
40 words
The device of claim 1 or 8 wherein said clamp means further comprises a spherically adjustable joint with lock means for locking said clamp means to said stabilizer arm's distal end in any given position within a range of positions.
Claim 14
Dependent Claim
12 words
The device of claim 1 wherein said lock means is hydraulically actuated.
