Abstract
Abstract A suspension device for a magnetic transducer including a spring member and a transducer attachment clip engaged by the spring member. Pivot means are disposed between the spring member and the attachment clip to define an axis of rotation. The device may include a retraction member adapted to engage the attachment clip and indexing means between the retraction member and the attachment clip to index the attachment clip when the retraction member engages the clip. The spring member and the retraction member may be integrally formed.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
76 words
A suspension device for magnetic transducers comprising: a spring member; a transducer attachment clip engaged by said spring member and adapted to be affixed to said transducer, said spring member adapted to apply biasing force to said attachment clip; and pivot means disposed between said spring member and said attachment clip for allowing said attachment clip to pivot with respect to said spring member, said pivot means defining an axis of rotation for said attachment clip.
Claim 2
Dependent Claim
76 words
A suspension device for magnetic transducers comprising: a spring member; a transducer attachment clip engaged by said spring member and adapted to be affixed to said transducer, said spring member adapted to apply biasing force to said attachment clip; and pivot means disposed between said spring member and said attachment clip for allowing said attachment clip to pivot with respect to said spring member, said pivot means defining an axis of rotation for said attachment clip.
Claim 3
Dependent Claim
100 words
A suspension device for magnetic transducers comprising: a spring member, a transducer attachment clip engaged by said spring member and adapted to be affixed to said transducer, said spring member adapted to apply biasing force to said attachment clip, pivot means disposed between said spring member and said attachment clip for allowing said attachment clip to pivot with respect to said spring member, said pivot means defining an axis of rotation for said attachment clip, and retraction member means adapted to engage a portion of said clip for applying retraction force to said clip substantially opposite to said biasing force.
Claim 4
Dependent Claim
100 words
A suspension device for magnetic transducers comprising: a spring member, a transducer attachment clip engaged by said spring member and adapted to be affixed to said transducer, said spring member adapted to apply biasing force to said attachment clip, pivot means disposed between said spring member and said attachment clip for allowing said attachment clip to pivot with respect to said spring member, said pivot means defining an axis of rotation for said attachment clip, and retraction member means adapted to engage a portion of said clip for applying retraction force to said clip substantially opposite to said biasing force.
Claim 5
Dependent Claim
57 words
A suspension device as in claim 2 wherein said retraction member means includes indexing means between said retraction member means and said portion of said attachment clip for indexing said attachment clip with respect to said spring member and said retraction member means when said retraction member means and said portion of said attachment clip are engaged.
Claim 6
Dependent Claim
92 words
A suspension device for a magnetic transducer comprising: a spring member; a transducer attachment clip engaged by said spring member and adapted to be affixed to said transducer, said spring member adapted to apply a biasing force to said attachment clip; pivot means disposed between said attachment clip and said spring member for allowing said attachment clip to pivot about an axis defined by said pivot means; and a retraction member adapted to engage said attachment clip to apply a retraction force to said attachment clip substantially opposite to said biasing force.
Claim 7
Dependent Claim
92 words
A suspension device for a magnetic transducer comprising: a spring member; a transducer attachment clip engaged by said spring member and adapted to be affixed to said transducer, said spring member adapted to apply a biasing force to said attachment clip; pivot means disposed between said attachment clip and said spring member for allowing said attachment clip to pivot about an axis defined by said pivot means; and a retraction member adapted to engage said attachment clip to apply a retraction force to said attachment clip substantially opposite to said biasing force.
Claim 8
Dependent Claim
47 words
A suspension device as in claim 4 wherein said retraction member includes indexing means between said retraction member and said attachment clip for indexing said attachment clip with respect to said pivot means and said retraction member when said retraction member and said attachment clip are engaged.
Claim 9
Dependent Claim
22 words
A suspension device as in claim 4 wherein said spring member and said retraction member are integrally formed from a resilient material.
Claim 10
Dependent Claim
28 words
A suspension device as in claim 4 wherein said spring member comprises a first spring element and a second spring element substantially parallel to said first spring element.
Claim 11
Dependent Claim
45 words
A suspension device as in claim 4 wherein said pivot means includes first and second edge portions carried by said spring member and third and fourth edge portions carried by said attachment clip engaged with said first and second edge portions to form a pivot.
Claim 12
Dependent Claim
23 words
A suspension device as in claim 5 wherein said indexing means includes an index tab and an opening for receiving said index tab.
Claim 13
Dependent Claim
47 words
A suspension device as in claim 9 wherein said index tab is fixed to said attachment clip and said opening is formed through said retraction member and wherein said opening is of varying width to thereby guide said index tab into a predetermined position within said opening.
Claim 14
Dependent Claim
236 words
A suspension device for a magnetic transducer comprising: a spring body including a first leaf spring, a second leaf spring disposed laterally parallel to said first leaf spring, and a retraction member generally parallel to and spaced from said leaf springs; a transducer attachment clip engaged by end portions of said first and second spring members and adapted to be affixed to said transducer, said first and second spring members adapted to apply a biasing force to said attachment clip; first pivot means disposed between said first spring member and said attachment clip and proximate said end portion of said first spring member for allowing said attachment clip to pivot with respect to said first spring member; second pivot means disposed between said second spring member and said attachment clip and proximate said end portion of said second spring member for allowing said attachment clip to pivot with respect to said second spring member, said first and said second pivot means defining a pitch axis of rotation for said attachment clip; said retraction member adapted to engage said attachment clip to apply a retraction force to said attachment clip substantially opposite to said biasing force; and said retraction member further including indexing means between said retraction member and said attachment clip for indexing said attachment clip with respect to said end portions and said retraction member when said retraction member and said attachment clip are engaged.
