Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
90 words
Manipulating pliers comprising a frame, a control handle at a first end of said frame, a gripper at a second end of said frame opposite the first end of said frame, and at least one coupling member extending between said control handle and said gripper, wherein said gripper comprises at least one movable gripping member, and further wherein said control handle and said movable gripping member are each coupled to said frame by a rolling bearing arranged between said frame and said control handle and said movable gripping member respectively.
Claim 2
Dependent Claim
90 words
Manipulating pliers comprising a frame, a control handle at a first end of said frame, a gripper at a second end of said frame opposite the first end of said frame, and at least one coupling member extending between said control handle and said gripper, wherein said gripper comprises at least one movable gripping member, and further wherein said control handle and said movable gripping member are each coupled to said frame by a rolling bearing arranged between said frame and said control handle and said movable gripping member respectively.
Claim 3
Dependent Claim
33 words
Manipulating pliers according to claim 1 wherein said control handle comprises a lever, said lever comprising a cylindrical contact surface engaging a first frame contact surface on the first end of said frame.
Claim 4
Dependent Claim
32 words
Manipulating pliers according to claim 2 wherein said at least one movable gripping member comprises a cylindrical contact surface engaging a second frame contact surface on the second end of said frame.
Claim 5
Dependent Claim
21 words
Manipulating pliers according to claim 3 wherein said first and second frame contact surfaces define circle segments and have identical radii.
Claim 6
Dependent Claim
27 words
Manipulating pliers according to claim 4 wherein said first and second frame contact surfaces are positioned on said frame such that their centers of curvature are identical.
Claim 7
Dependent Claim
48 words
Manipulating pliers according to claim 1 wherein said rolling bearings comprise first and second frame contact surfaces and cylindrical contact surfaces on said control handle and on said movable gripping member, and said pliers additionally comprise a plurality of flexible straps to prevent slippage of said rolling bearings.
Claim 8
Dependent Claim
18 words

Claim 9
Dependent Claim
22 words
Manipulating pliers according to claim 6 wherein each flexible strap has a thickness proportional to a smallest radius of the rolling bearings.
Claim 10
Dependent Claim
75 words
Manipulating pliers according to claim 3 wherein said control handle further comprises a control roller comprising said first cylindrical contact surface engaging said first frame contact surface, and said movable gripping member further comprises a gripping member roller comprising said second cylindrical contact surface engaging said second frame contact surface, and said control roller and said gripping member roller are coupled to each other by said at least one coupling element to be substantially torque-resistant.
Claim 11
Dependent Claim
17 words
Manipulating pliers according to claim 9 wherein said at least one coupling element comprises a tension rod.
Claim 12
Dependent Claim
19 words
Manipulating pliers according to claim 9 wherein said at least one coupling element comprises at least one spring element.
Claim 13
Dependent Claim
53 words
Manipulating pliers according to claim 11 wherein said at least one coupling element comprises two spring elements, wherein a first spring element couples said control roller to said frame, and said second spring element couples said gripping member roller to said frame, and wherein said spring elements are in balance with each other.
Claim 14
Dependent Claim
17 words
Manipulating pliers according to claim 9 wherein said at least one coupling element comprises two tension rods.
Claim 15
Dependent Claim
31 words
