Abstract

A fingered member for a downhole tool that includes: a circular body; a plurality of fingers extending from the circular body; a recessed region formed in the circular body; a void formed between respective fingers; and a transition zone between the circular body and the plurality of fingers. The transition zone further includes an inner surface and an outer surface.

Claims (31)

1. A fingered member for a downhole tool comprising:

a circular body comprising a transition zone having an inner surface and an outer surface;

a plurality of fingers extending from the circular body;

a recessed region formed in the circular body; and

a longitudinal void formed between respective fingers, and extending from respective ends to the circular body

wherein the fingered member is made from a composite material, and wherein the circular body is annular, one-piece, and configured for fitting around a mandrel, wherein at least one end of one of the plurality of fingers comprises a respective outer tapered surface, and wherein a first annular groove is disposed within the inner surface.

2. The fingered member of claim 1 , wherein a second annular groove is disposed within the outer surface.

3. The fingered member of claim 1 , wherein each of the plurality of fingers comprises a respective outer tapered surface.

4. The fingered member of claim 3 , wherein the composite material comprises one or more of filament wound material, fiberglass cloth wound material, and molded fiberglass composite.

5. A fingered member for a downhole tool comprising:

a circular one-piece body configured for fitting around a mandrel;

a plurality of fingers extending from the circular one-piece body;

a longitudinal void formed between respective fingers, and extending from respective ends to the circular one-piece body; and

a transition zone being part of the circular one-piece body, and further comprising an inner surface and an outer surface,

wherein a first annular groove is disposed within the inner surface, and a second annular groove is disposed within the outer surface, and

wherein at least one end of one of the plurality of fingers comprises an outer tapered surface.

6. The fingered member of claim 5 , wherein each of the plurality of fingers comprises a respective outer tapered surface.

7. The fingered member of claim 6 , wherein the fingered member is made from a composite material.

8. The fingered member of claim 7 , wherein the composite material comprises one or more of filament wound material, fiberglass cloth wound material, and molded fiberglass composite.

9. A fingered member for a downhole tool comprising:

an annular one-piece body configured for fitting around a mandrel, and further comprising a transition zone having an inner surface and an outer surface,

a plurality of fingers extending from the annular one-piece body; and

a longitudinal void formed between respective fingers, and extending from respective ends to the annular one-piece body; and

a first annular groove disposed within the inner surface,

wherein at least one end of one of the plurality of fingers comprises an outer tapered surface, and

wherein the fingered member is made from a composite material.

10. The fingered member of claim 9 , wherein each of the plurality of fingers comprises a respective outer tapered surface.

11. The fingered member of claim 10 , wherein the composite material comprises one or more of filament wound material, fiberglass cloth wound material, and molded fiberglass composite.

12. The fingered member of claim 11 , wherein a second annular groove is formed in the outer surface.

13. The fingered member of claim 12 , wherein the second annular groove is formed in the outer surface proximate to a recessed region.

14. The fingered member of claim 13 , wherein the composite material comprises one or more of filament wound material, fiberglass cloth wound material, and molded fiberglass composite.
