Abstract
Abstract A rotary mount flexural pivot is disclosed which is integrally formed from a single piece of feed stock and which uses no mechanical connections. Two hollow cylindrical mounts are axially aligned and at least two flexural members are disposed on the interior of these two mounts, are integrally interconnected with each of these two mounts, and cross to define an intersection. These two flexural members are integrally interconnected with each other along the entire extent of this intersection. The mounts therefore move relative to each other by a relative rotation about the flexural member intersection.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
404 words
A flexural pivot, comprising: a first mount comprising a first hollow cylindrical mounting portion and a first tab extending from an end of said first cylindrical mounting portion, wherein said first cylindrical mounting portion comprises a first interior surface and a first exterior surface, wherein said first tab comprises a first interior surface and a first exterior surface; a second mount comprising a second hollow cylindrical mounting portion and a second tab extending from an end of said second cylindrical mounting portion, wherein said second cylindrical mounting portion comprises a second interior surface and a second exterior surface, wherein said second tab comprises a second interior surface and a second exterior surface, wherein said first tab of said first mount extends into an interior of said second cylindrical mounting portion of said second mount whereby said first exterior surface of said of said first tab interfaces with said second interior surface of said second cylindrical mounting portion, wherein said second tab of said second mount extends into an interior of said first cylindrical mounting portion of said first mount whereby said second exterior surface of said second tab interfaces with said first interior surface of said first cylindrical mounting portion, wherein said first and second cylindrical mounting portions of said first and second mounts, respectively, are axially aligned; and first and second flexure member integrally interconnected with each of said first and second mounts, said first flexure member being integrally interconnected with said first interior surface of said first cylindrical mounting portion of said first mount and being integrally interconnected with said second interior surface of said second tab of said second mount, said second flexure member being integrally interconnected with said second interior surface of said second cylindrical mounting portion of said second mount and being integrally interconnected with said first interior surface of said first tab of said first mount, wherein said first and second flexure members cross at an intersection and are integrally interconnected with each other along substantially an entire extent of said intersection, wherein said first and second mounts are movable relative to each other by a flexing of said first and second flexure members by a rotation of said first cylindrical mounting portion relative to second cylindrical portion substantially about said intersection and wherein said flexural pivot is integrally formed from a single piece of feed stock as a unitary structure which is free from any mechanical connection.
Claim 2
Dependent Claim
404 words
A flexural pivot, comprising: a first mount comprising a first hollow cylindrical mounting portion and a first tab extending from an end of said first cylindrical mounting portion, wherein said first cylindrical mounting portion comprises a first interior surface and a first exterior surface, wherein said first tab comprises a first interior surface and a first exterior surface; a second mount comprising a second hollow cylindrical mounting portion and a second tab extending from an end of said second cylindrical mounting portion, wherein said second cylindrical mounting portion comprises a second interior surface and a second exterior surface, wherein said second tab comprises a second interior surface and a second exterior surface, wherein said first tab of said first mount extends into an interior of said second cylindrical mounting portion of said second mount whereby said first exterior surface of said of said first tab interfaces with said second interior surface of said second cylindrical mounting portion, wherein said second tab of said second mount extends into an interior of said first cylindrical mounting portion of said first mount whereby said second exterior surface of said second tab interfaces with said first interior surface of said first cylindrical mounting portion, wherein said first and second cylindrical mounting portions of said first and second mounts, respectively, are axially aligned; and first and second flexure member integrally interconnected with each of said first and second mounts, said first flexure member being integrally interconnected with said first interior surface of said first cylindrical mounting portion of said first mount and being integrally interconnected with said second interior surface of said second tab of said second mount, said second flexure member being integrally interconnected with said second interior surface of said second cylindrical mounting portion of said second mount and being integrally interconnected with said first interior surface of said first tab of said first mount, wherein said first and second flexure members cross at an intersection and are integrally interconnected with each other along substantially an entire extent of said intersection, wherein said first and second mounts are movable relative to each other by a flexing of said first and second flexure members by a rotation of said first cylindrical mounting portion relative to second cylindrical portion substantially about said intersection and wherein said flexural pivot is integrally formed from a single piece of feed stock as a unitary structure which is free from any mechanical connection.
Claim 3
Dependent Claim
22 words
A flexural pivot, as claimed in claim 1, wherein: adjacent ends of said first and second cylindrical mounting portions are axially spaced.
Claim 4
Dependent Claim
37 words
A flexural pivot, as claimed in claim 1, wherein: said first and second flexure members are each substantially the same length, and wherein said intersection has a length substantially equal to a length of said flexural pivot.
Claim 5
Dependent Claim
71 words
A flexural pivot, as claimed in claim 1, wherein: a length dimension of each of said first and second mounts is substantially parallel with said intersection about which said first mount moves relative to said second mount, wherein said first and second flexure members are each interconnected with each of said first and second mounts along substantially an entirety of said length dimension of each of said first and second mounts.
Claim 6
Dependent Claim
43 words
A flexural pivot, as claimed in claim 1, wherein: movement of said first mount relative to second mount about said intersection causes said first flexure member to bend in a clockwise direction and said second flexure member to bend in a counterclockwise direction.
Claim 7
Dependent Claim
79 words
A flexural pivot, as claimed in claim 1, wherein: said first interior surface of said first mounting portion and said second interior surface of said second mounting portion each comprise a recess, wherein said first tab of said first mount is disposed within said recess on said second interior surface of said second mounting portion and wherein said second tab of said second mount is disposed within said recess on said first interior surface of said first mounting portion.
Claim 8
Dependent Claim
69 words
A flexural pivot, as claimed in claim 1, wherein: said first exterior surface of said first tab of said first mount is radially spaced from said second interior surface of said second mounting portion of said second mount and wherein said second exterior surface of said second tab of said second mount is radially spaced from said first interior surface of said first mounting portion of said first mount.
