Perimetrically loading collet
View Patent ↗A perimetrically acting collet includes a body and at least one mating profile opening in the body. A plurality of resilient members located adjacent one side of the at least one mating profile opening and a profiled body is biased perimetrically by the plurality of resilient members.
1. A perimetrically acting collet comprising:
a body;
at least one mating profile opening in the body;
a plurality of resilient members and a plurality of resilient member openings adjacent one side of the at least one mating profile opening, at least one of the plurality of resilient member openings having at least one bridge; and
a profile in the body, biased perimetrically by the plurality of resilient members.
2. A perimetrically acting collet as claimed in claim 1 wherein the plurality of resilient members comprises a part of the body of the collet.
3. A perimetrically acting collet as claimed in claim 1 wherein the plurality of resilient member openings is three resilient member openings adjacent each other.
4. A perimetrically acting collet as claimed in claim 1 wherein the collet further includes a helical profile capable of orienting the collet when contacting a mating profile.
5. A perimetrically acting collet as claimed in claim 1 wherein the mating profile opening has a positive stop feature.
6. A perimetrically acting collet as claimed in claim 1 wherein the profile is complementary to a mating profile.
7. A perimetrically acting collet as claimed in claim 1 wherein the profile is teeth.
8. A perimetrically acting collet as claimed in claim 1 wherein the profile includes a positive stop feature complementary to a shape of a member receivable therein.
9. A perimetrically acting collet as claimed in claim 1 wherein the collet is a selective collet configured to pass non-complementary mating profiles and positively stop at a complementary mating profile.
10. A perimetrically acting collet as claimed in claim 1 wherein the mating profile opening is about 60 degrees of arc measured around the periphery of the body.
11. A perimetrically acting collet as claimed in claim 1 wherein the body includes a helical profile on a leading longitudinal end thereof.
12. A perimetrically acting collet as claimed in claim 1 wherein the at least one bridge affects the perimetrical bias that the plurality of resilient members places on the profile in the body.
13. A method for engaging a mating profile downhole
comprising:
approaching the mating profile with a perimetrically acting collet, the collet having a plurality of resilient members and a plurality of resilient member openings adjacent one side of at least one mating profile opening, at least one of the plurality of resilient member openings having at least one bridge;
perimetrically deflecting the collet; and
perimetrically engaging the mating profile.
14. A method for engaging a mating profile downhole as claimed in claim 13 wherein the method further comprises stopping traveling movement of the collet by a stop.
