Abstract
Abstract A lockable remote center compliance (RCC) device is provided including: a deformable support structure and an operator member having a first section attached to the support structure and a second section incorporating the free end of the operator member. A frame proximate the free end of the operator member supports the support structure. Locking is accomplished by first and second parts carried one by the operator member and the other by the frame, for releasably securing the operator member to the frame. The operator member sections are moved relative to one another to engage the first part with the second part to secure the free end of the operator member against compliant action.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
121 words
A lockable remote center compliance (RCC) device comprising: a deformable structure; an operator member having a first section attached to said deformable structure and a second section incorporating the free end of said operator member; means for supporting said deformable structure including: frame means proximate the free end of said operator member; locking means including first and second parts carried one by said second section of said operator member and the other by said frame means for releasably securing said operator member to said frame means; and means for moving said sections relative to one another to engage said first part of said locking means with said second part to secure the free end of the operator member against compliant action.
Claim 2
Dependent Claim
121 words
A lockable remote center compliance (RCC) device comprising: a deformable structure; an operator member having a first section attached to said deformable structure and a second section incorporating the free end of said operator member; means for supporting said deformable structure including: frame means proximate the free end of said operator member; locking means including first and second parts carried one by said second section of said operator member and the other by said frame means for releasably securing said operator member to said frame means; and means for moving said sections relative to one another to engage said first part of said locking means with said second part to secure the free end of the operator member against compliant action.
Claim 3
Dependent Claim
24 words
The device of claim 1 in which one of said sections includes a hole and the other a slide member slidable in said hole.
Claim 4
Dependent Claim
23 words
The device of claim 2 in which said means for moving includes spring means which urges the slide member out of the hole.
Claim 5
Dependent Claim
24 words
The device of claim 2 in which said means for moving includes means for applying fluid pressure to said slide member in said hole.
Claim 6
Dependent Claim
30 words
The device of claim 4 in which said means for moving further includes spring means which urges said slide member into said hole against the force of said fluid pressure.
Claim 7
Dependent Claim
14 words
The device of claim 1 in which said means for moving includes spring means.
Claim 8
Dependent Claim
29 words
The device of claim 1 in which said first part includes a plurality of locking pins and said second part a plurality of locking holes for receiving said pins.
Claim 9
Dependent Claim
24 words
The device of claim 7 in which said locking pins are tapered to a smaller width at their ends which engage said locking holes.
Claim 10
Dependent Claim
20 words
The device of claim 7 in which said first part including said locking pins is carried by said frame means.
Claim 11
Dependent Claim
49 words
The device of claim 1 further including anti-rotation means for limiting rotation of said operator member relative to said frame means when said locking means are disengaged and having first and second components mounted one on said second section of said operator member, the other on said frame means.
Claim 12
Dependent Claim
32 words
The device of claim 10 in which said first component includes a plurality of anti-rotation pins and said second component includes a plurality of anti-rotation holes for loosely receiving said anti-rotation pins.
